The dry click of the padlock finally giving up felt way louder than it actually was. Despite the docks being pretty much abandoned at this time of day, Sienna couldn’t simply go around stomping like an elephant. The odd security guard or, if the tip she’d received turned out to be true, the people she were looking for could turn up to investigate. Sliding her picks back into their pristine leather case and slipping that back into her pocket, the young private investigator pulled her dark, ash blonde hair back into a ponytail. It left her neck exposed to the frigid, moist air, but better than having her shoulder length locks poke into her eyes in a moment of crisis. Slipping on her leather gloves, Sienna carefully pulled the padlock free, before pushing the warehouse door open. Having a last look around to confirm she was alone, the young woman gingerly took her first steps into the darkness of the building.

It was a moonless night, but even otherwise it would have been impossible to see inside the windowless structure. Reluctant to draw any attention to herself, the girl detective pulled a flashlight out of her tool belt, clicking it on to the lowest setting. Carefully, she directed the beam of light onto the ground in front of her, before sweeping her immediate surroundings. Packaging materials, crates filled with spare parts and large containers were strewn about. Not the most coordinated warehouse, for sure, Sienna thought. But the messy layout wasn’t just a visual annoyance for the young detective; it also meant that danger could be lurking anywhere. Stepping carefully forward, she raised the flashlight to see a couple of metres in front of her. Passing by a container with a rust pattern that weirdly drew her attention, Sienna almost fell forward into the briny, cold seawater lapping at her sneakers. Inhaling sharply, the young woman jumped away from the canal, only to bump into a workbench with her plump behind, sending something metallic clattering onto the concrete floor.

Sienna grit her teeth at the incredulous amount of noise, hand reaching for her pocket knife while shutting off her torch. She didn’t own a weapons licence, leaving her with only a couple of options in the self-defence front; a pocket knife with a blade just barely longer than her palm and a can of illegal pepper spray. Holding her breath for almost a full minute, waiting for the reverberations of the metallic sound to die down, the detective finally let it out in relief. She was alone in the warehouse after all. At least, she believed that for a couple more seconds, right until the echo of a soft moan reached her ears. Excitement gripped her heart almost immediately. The tip had actually paid off! Something was indeed going on in these docks. And Sienna Cross was about to find out. Flicking her flashlight on again, she advanced further into the warehouse, listening for the clearly feminine sounds emanating from somewhere deep within.

Despite her careful examination of her surroundings. Sienna didn’t find any signs that there was anyone else in the warehouse, other than her and the person still letting out the occasional moan, accompanied by a persistent buzzing. Whether intentional or not, the sounds led the investigator directly to their origin, a naked, dark haired woman bound to the rafters above with a long strand of rope, her toes barely touching the moist floor. She was blindfolded and gagged with the biggest ball-gag Sienna had ever laid eyes on, stark naked save for a pair of straps that held a long tube-like thing between her legs. It took the young detective a couple of seconds to unglue her eyes from the voluptuous, struggling female, and another few to figure out that the tube was actually a wand vibrator. Despite the chilling air permeating the room, the captive was dripping with sweat, seemingly having dealt with the vibrations for quite some time. Sienna watched in stunned silence as the woman’s moans reached a peak, thrashing in her bonds as what seemed to be a very pleasurable orgasm ripped through her body.

Taking another look around her, half-covering her flashlight with her free palm, Sienna decided to carefully approach the bound woman. Through the face coverings, she could make out that the woman was quite older than her, somewhere in her late thirties. Even so, she stood taller than the detective, with her melon-sized breasts standing upright. Unable to stop her wandering eyes, Sienna took in the rest of the woman, her hourglass shaped waist, the soft, wobbly rear and the full thighs beneath. She didn’t match the description of the missing girl the young woman had been investigating, not by a long shot; alas, she was clearly in need of help. Taking a quick look around, Sienna crouched, searching for the off switch on the vibe. It took her a moment, seeing as she kept being distracted by the flexing muscles and the moaning of the struggling woman. The moment she touched the vibe, the woman froze, stifling a moan on its way out as her body tensed up. With the buzzing dying down, an eerie silence swept over the room, only to be broken by a quizzical groan from the bound woman.

“I’m here to help.” Sienna whispered. “Give me a second; I’ll have you out of these ropes in no time.”

Dragging over a conveniently placed wooden crate, the young investigator hopped on, leaning over the woman as she sawed through the ropes with her trusty pocket knife. It was a quick deal, as the ash-haired girl kept the knife sharp. The rope snapped and the woman landed on wobbly feet, losing her balance and grasping at anything so as to not fall over. Which happened to be Sienna herself. With both of them toppling over, the woman landed onto the wooden crate with a muffled grunt, while the detective landed on her back, hard. It knocked the wind out of her chest, sending her knife and flashlight flying out of her grasp. She struggled for a few seconds, trying to breathe while simultaneously trying to pick herself up. The naked woman pushed off the crate, illuminated by the loose torch as she reached up to pull the blindfold free and undo the gag. Tired, light brown eyes tried to focus on the investigator, struggling against the light beam. Seemingly dizzy, she leaned her rear on the crate with a thud, a hand covering her eyes.

“Hey, it’s okay.” Sienna said, having found her breath and slowly taking to her feet. “You’re free. I’ll help you get out of here.”

The woman looked over at her again, as if trying to assess her intentions. Sienna stood with her open palms raised to shoulder height, giving her a reassuring smile. Eventually, the naked woman nodded her head, clearing her throat. Before she could speak however, her eyes snapped to something behind the young detective. It was a moment too late as Sienna noticed the light was moving behind her. Turning on her heels, she almost came face to face with the man standing behind her. Jumping back in surprise, the private investigator immediately raised an arm protectively over the naked woman now behind her, while the other slipped into her pocket, in search of a knife that wasn’t there.

“Whoa there.” Said the man in a calm, collected tone. He lowered the torch, allowing Sienna a good look at him. He was of a tall but rather slim build, with salt showing on the sides of his slicked back, pepper black hair. “Calm down, Miss Cross.” He added, holding up her pocket knife as well.

“Who are you?” How do you know my name?” Asked the young detective, her voice cracking more than she would have liked. “I won’t let you hurt this woman any more!”

“Please, there is no need for this animosity.” The man said gently, while taking a step forward.

His leather shoes looked expensive, as did the suit pants and coat he was wearing. Not dressed as your regular goon, that’s for sure, Sienna thought. Which made him even more dangerous in the private investigator’s eyes. She reached for the can strapped to her lower back, pulling it forward and uncapping it with one fluid, practised motion.

“Stay back!”

“As I said, Miss Cross, there is no need for violence.” The man said, though he stopped moving. “I am only here on business.”

“Your business with this poor woman is done!” Sienna said, lifting the can in front of her, ready to press the trigger. “She is leaving with me.”

“But, Miss Cross, my business is with you.”

“What…? We have no business!”

“Your intense reactions tell me that we do, more than you realise.” The man said with the same, calm tone. “As for the woman…”

Sienna felt a sharp sting on the side of her exposed neck, then a short moment of pressure. With wide eyes, she turned to see if someone had snuck up on her, only to find the naked woman smiling widely, an empty syringe between her fingers. In shock, she raised her free arm to touch the stung area, but her hand felt heavy, her movements sluggish. It felt as if it took her a full minute to lift her arm, only for her fingers to feel completely numb as she pressed them against her tender flesh. Feeling like she was moving through jelly, Sienna turned towards the man, pushing down on the trigger of the pepper spray. Her fingers refused, and the can slipped out of her grasp, the man snatching it easily out of the air.

“…She happens to be my assistant.” He continued.

Sienna crumbled under her own weight as her limbs lost all feeling, followed by her lips, throat and tongue. She could just barely move her eyes and eke out a tiny breath; maybe cause a finger to twitch, just barely.

“Mrs Morris, I believe I told you to only use half of the dosage!” The man said. “This amount might have unwanted… side effects.”

Even during her struggling to recuperate, the name uttered set off alarm bells inside Sienna’s head. She had heard of that name somewhere before. It must have been a long time ago though, seeing as she could barely remember where or when.

“It’s fine, Doctor!” Said the woman in an overly cheery voice. “She’s a big girl. She can take it!”

Sienna watched out of the corner of her eye the man press his fingers up against the ridge of his nose, shaking his head in disappointment.

“Please, get dressed and prepare for the transfer.” He said, handing a suitcase to the naked woman, who nodded enthusiastically.

He procured a pair of glasses out of his breast pocket, before making his way to the now paralyzed investigator, sitting down on his haunches and looking her over.

“I’m terribly sorry for this, Miss Cross.” He said while pulling a pair of black, single-use latex gloves out of his pocket and slipping them on. “I was informed of your condition, yes, but not of the severity. Please excuse me as I examine you myself.”

Wielding Sienna’s own pocket knife, the mysterious man slipped a pair of fingers under her jacket collar, pulling it away from her body before ripping through it with the blade. The sharpened knife cut through the jacket and her blouse beneath like butter and soon enough, both articles had been sliced open. With the same, unsettling ease, the man proceeded to cut off both sleeves, before tossing the tattered remains of shirt and jacket aside with little care. It seemed that whatever had been used to paralyse her, didn’t remove her ability to sense and feel things, as evident by the chill running down her spine when her naked back touched the freezing concrete. Unclasping her tool belt and tossing it aside as well, the man then hooked a finger into her jeans, slicing once down each pant leg. Left with only her matching, pearly white underwear, Sienna was horrified at her inability to react while being methodically stripped by the unsettling man. She couldn’t make heads or tails of him and his claims of her ‘condition’, or his smooth and soft demeanour. Something must be seriously fucked behind those eyes, the detective thought. Fear, actual fear, began creeping up her spine. She was at his complete mercy and it terrified her beyond belief.

“There doesn’t seem to be a loss of bladder control.” He announced with an underlining of relief, seemingly to himself. “That is something, at least.”

Her sneakers and socks followed the rest of her clothes, with the man then making quick work of her bra and panties, cutting through all the straps with ease. Now stark naked, freezing and unable to cover up or even shiver to keep warm, Sienna dreaded whatever the hell would follow. Stripping her buck naked certainly wasn’t a sign of good things to come. Tossing the knife onto the growing pile of her belongings, the man reached into his coat pocket, pulling out a notepad and a pen. Flipping it open, he then took the time to stare up and down the body of the naked girl splayed out before him. Sienna felt her cheeks burn with shame and humiliation, but also with anger; anger at herself for falling so easily into this trap, leaving her at the mercy of this outlandish pair.

“There appears to be a clear hardening of the teat, possibly in response to being seen naked.” The man exclaimed, as if stating his ‘findings’ to someone unseen, all the while scribbling away at his notepad. “An intense flushing of the cheek and upper chest, indicating arousal, which…”

He stopped scribbling, only to reach over Sienna’s mound with a gloved hand, and dip his fingers between the cleft of her legs, rubbing over and under the soft folds therein. Sienna felt him fiddling around her sex, looking away in shame and disgust as she was violated in this way. The man touched and felt around until he found the entrance to her flower, running a pair of fingers over it, then pulled his hand free. Out of the corner of her eye, the paralyzed girl watched as he separated his fingers, a string of sticky liquid hanging between them. At first, she thought that he had smeared something over her sex, anxiety rising at whatever it could have been. But then she figured out the more obvious, although worrying answer. The liquid was her own excitement, dripping out of her for some unthinkable reason.

“… is confirmed by the clear secretion of natural lubrication in the subject’s vaginal cavity.” He continued, reminding Sienna of a doctor performing an examination. “There is no doubt, as is confirmed by my preliminary examination; Miss Cross is aroused by her current predicament.”

Sienna felt her blood boil at the statement, glaring at the man in disbelief. Her nipples were hard because of the freaking cold, her cheeks and chest flushed because of her embarrassment at being stripped naked. The so-called ‘findings’ were bogus, a forging of evidence that anyone with half a brain would have figured out were the results of location and not condition. She would have told him as much, if she could. She would have said a lot more than that, in fact, but she suspected that even if she could speak, her arguments would fall on deaf ears; the man and his assistant were clearly not of sound mind. Whatever game the man was playing, he seemed to believe in it wholly, perhaps even conceiving it as truth. Fear clutched at Sienna’s heart. With any other man, she could have guessed what would have happened to her. The way he spoke and his remarks scared her even more than the prospect of being ravaged did.

“There is only one conclusion,” the unsettling man said, back to scribbling at his notepad. “Miss Cross is suffering from an undiagnosed, acute form of nymphomania and shows clear signs of repressed masochism. She is in dire need of treatment.”

Sienna couldn’t believe her ears! What the hell was this man saying? What was this twisted game he was playing? Her heart skipped a beat as genuine terror gripped it at the mention of ‘treatment’. What did he mean by that? What did any of it mean? How had she gotten herself into this mess? The man, seemingly oblivious to the panic that had enveloped the detective, flipped his notepad closed and took a step closer to Sienna’s head, gently gripping her chin and making her look at him. He gave her what could have passed as a kind smile in any other circumstance, but currently only served at scaring the woman even more.

“Do not worry, Miss Cross.” He said softly. “We caught it in time; and, thanks to the tip we received, my assistant and I have the proper means to transfer you to our facility and treat you.”

Having said that, he nudged her face gently to the side, bringing the crate she’d used to help the woman in view. The woman was there now, dressed up in a latex mock-up of a nurse’s outfit. Glistening high-heeled boots ending just over her knees, a pair of thigh-highs connected to a garter belt visible over her rosy-white skin before disappearing under the hem of an extremely short, white skirt. Above that, the straps of a thong were clearly visible as they hugged the woman’s shapely waist. Her entire navel was exposed, with a tight, white button-down shirt covering her ample chest, leaving a ridiculous amount of cleavage visible. Her arms were covered by a pair of elbow length gloves, as was her mouth by a surgeon’s mask. Her dark brown hair had been pulled back into a bun, completing the look of a heavily fetishized medical assistant. A different kind of shiver ran down Sienna’s spine as she took in that distressing sight.

The assistant, as if on cue, turned the crate to its side with a bit of effort and unlatched it, allowing the side to fall down and reveal the contents. A pinkish foam-like material, similar in look to the stuff packing peanuts were made of, covered the walls of the crate, with obvious and very suggestive cut-outs made into it. The man slid a hand behind the nape of her neck and another behind the small of her back, hoisting her up onto her rump and allowing her to see better. Sienna didn’t appreciate the shift at all, as she could now look into the cut-outs. The bottom part had a pair of large, phallic shapes extending from it, with another, shorter and more round metallic part next to them. On the same side, a rather indicative shape of where a pair of breasts would fit had a pair of small tubes attached, right where the nipples on said breasts would be.

“These machines are here to keep your cravings in check during transport.” The man explained. “The crate is also completely soundproof, so don’t worry about having to hold back; you can scream to your heart’s content with no fear of someone hearing. We pride ourselves at being discreet with our patients and avoiding any embarrassing encounters with… less understanding folk.”

Fight or flight kicked in, making Sienna want to scramble to her feet, run away and hide forever in a safe, dark hole. The only thing she could do, however, was move the digits on her right hand; barely.

“I can see she’s already eager to test them out, Doctor!” Said the nurse, while staring into the investigator’s bright, blue eyes. “Her eyes are all wide with excitement!”

“Indeed, Mrs Morris.” The doctor chimed in. “Let’s get her set up.”

Sienna watched on as the ‘nurse’ slid the top off of the crate as well, setting it aside before walking over to help the ‘doctor’ lift her limp body up. With the two of them holding one arm each, they led the detective into the crate, aligning her legs with the shapes in the foam, which seemed to be oddly the correct size for them. They lowered her to her knees, the man grabbing her around the waist and chest, while the woman leaned down and began fitting and tightening strap after strap over the naked girl’s legs. Her ankles were first, then her calves, then the insides of her knees. Sienna was then brought to a sitting position, her lower orifices lined up with the phalluses beneath. She could barely wince as she was plunged onto them, the front one sliding easily between her folds. The one in her rear needed a bit more finesse and some added pressure, but eventually the pair managed to pop it inside her. The young detective wanted to scream in pain, but all she could muster was a stream of air gently flowing out her nose.

“Nurse, I believe I asked you to specifically lubricate the tools for use earlier.” The man said, annoyance colouring his voice.

“Oops!” the woman responded in an almost child-like manner.

More straps were tightened over Sienna’s lower and upper thighs, forcing her even deeper on her invaders, while the smaller metal part pushed up against her clit. Each hand of hers was gently turned into a fist, then fitted into a leather pouch that held her fingers to her palms, what little movement she had regained lost to the inescapable bondage. Her arms were then folded behind her back, a set of straps binding her wrists to opposite elbows, with a larger one being fitted over her arms and under her tits, holding everything in place. Her whole upper body was pushed into the form-fitting opening, her breasts sitting perfectly comfortable in their cut-outs. Even in her panic, Sienna realised that whoever had given the tip-off to the odd pair, had also provided them with more or less her exact measurements. Someone that somehow had intimate knowledge of her and her body. Try as she might, she couldn’t focus enough to figure out who could have been the informant.

The young detective’s eyes widened in horror as she saw what was being prepared for her next. The ‘nurse’ used her gloved fingers to part Sienna’s lips, holding her mouth open for what appeared to be a gag with a small bulb on the inside. The ‘doctor’ pulled her ash-blonde ponytail up gently, allowing for the nurse to tighten the gag around her slender neck, until the part inside her mouth sat comfortably behind her teeth. The bulb itself wasn’t all that big, barely tickling the top of her tongue as it lay flat, but the twin tubes running out the other side were what worried the investigator. As if responding to her thoughts, the man gently took hold of them both, showing her where each one led. The thinner one ended just a few centimetres away, connected to a pump and a valve, while the big one ran all the way to the top part of the crate, seemingly feeding through the inner lining and wood to allow her to breathe.

The ‘doctor’s’ hand palmed the pump and squeezed; immediately, the bulb in Sienna’s mouth began expanding in all directions, filling out the area behind her teeth and pushing down on her tongue. A couple of squeezes filled out her entire mouth, pushing against the back of her throat. Even if Sienna was able to scream, the inflated bulb causing her to gag would make sure she couldn’t. The breathing tube brought a taste of plastic down her gullet, but at least her lungs could fill with precious oxygen. With her body now completely restrained, the ‘nurse’ closed and latched the side of the crate, the foam-like material hugging the young detective firmly, leaving only the upper half of her head still visible. The woman leaned up on the crate, directing Sienna to watch as the man gathered up all of her torn clothes and belongings, tossing them inside a nearby large barrel; all except for her panties. He pulled a plastic bottle out of his pocket and emptied the contents into the barrel, before tossing that inside too. Then, with a dry click, he ignited a lighter, holding the torn undergarment over the flame until it lit up, dropping it into the barrel. Immediately, flames sprung up, licking at the barrel’s brim.

“If you’re wondering, the dosage for your paralysis was indeed the right amount.” The woman whispered, making sure only the ash-blonde could hear her. “I just mixed in a bit of an aphrodisiac. To help with the Doctor’s verdict.”

Sienna watched on in horror as her belongings burned, consigning her to nudity. Her wallet, driver’s licence, her house keys; everything lost. Despair flooded her belly at the woman’s statement, making her sick. In what could be almost considered mercy, she wasn’t made to look for much longer, as the ‘nurse’ lowered a goggle headset coupled with earphones over her eyes and ears, plunging her into a silent darkness. She was left there for a while, counting her breaths to figure just how much time had passed. The smell of her belongings burning was the only other connection to the world around her. At least she wasn’t cold anymore. The young investigator could only hear her own heartbeat, along with the occasional muffled gag as her throat convulsed around the intruder. Ever so slowly, the feeling of control returned to her extremities, allowing her to flex her fingers and wiggle her toes. She could blink, though it changed absolutely nothing; all she could see was pitch-black darkness. Her motor controls would be too late in recovering to help her escape. Hell, she could barely breathe with how tight the foam was around her naked form.

After a few more minutes, or her best approximation of that time, Sienna finally felt something change, but not for the better. Form-fitting foam hugged the top of her head, pushing her down until her chin rested on top of the cut-out made for it. The headset was firmly pressed up against her face, as were the headphones. A snapping vibration let the detective know that the crate had been closed and sealed. In some ways, she was thankful for the paralysing effect still holding on, as it prevented her from hyperventilating and possibly passing out. Thanks to that, the panic and terror, while still gripping her heart and stomach so tight she felt they would burst, had not overwhelmed her. She could still think, though not all that clearly, about her situation. That was until a sudden ping sound played from the headphones, making her nearly jump out of her skin. A second later, her eyes were assaulted with a bright light, forcing the girl to wince and shut them tight. The goggles appeared to actually be a type of VR headset, accompanied by the headphones. As her eyes slowly adjusted to the brightness, Sienna opened them to see an image that sank her heart even more. It was a picture, taken and probably sent via a cellphone, of the crate she was in, locked and sealed tight.

While still ogling the picture, looking for any tells that might alert anyone seeing it that she was inside, Sienna felt the crate shift and move, tilting backwards. The subtle vibrations told her she was being moved on wheels. At the same time, the screen in front of her eyes switched to something resembling a hardcore BDSM porn video, but with the audio set way low. A few seconds into the video, the ‘doctor’s’ recorded voice came in, mixed with the moans of the displayed woman being teased in bondage.

“Welcome to our trouble-free, travel-safe patient transportation device!” Said the man cheerfully, not unlike a salesman on a sleazy car-sales advertisement reel set to play after midnight on TV. “This video is part of our premium service, recorded in our very own studio, and it’s here to help you acclimatise to your new situation. Please keep your eyes on the screen at all times, as there are consequences for missing out, and remember to breathe through your mouth!”

Sienna couldn’t believe her eyes and ears. What the fuck was wrong with these people? Was this some sort of sick, twisted prank? It would explain how the pair knew of her exact body dimensions, as well as their convenient appearance to the location tipped off to her. But nothing else about this felt like a prank. Her personal effects being burned, the violation of her body, not to mention drugging and stripping her could in no way be endorsed by anyone she knew. She shut her eyes, unwilling to keep watching this disturbing show, only to be rewarded with a sudden surge of electricity coursing through her body, making her muscles clench painfully, despite the paralyzer still in effect. Unable to scream, Sienna could only open her eyes wide, a couple of tears forming on their edges. The shock felt as if it came from everywhere at once. Her confusion was not left unanswered for long however, as the recording in her ears cut out, only for another to take its place.

“Please do not attempt to look away from the screen or close your eyes,” said the man in a more stern voice. “There is a sensor in your visor, capable of recognising movement of the eyelids. Any and all digressions will be swiftly reprimanded by a high-voltage current, discharged through a number of electrodes fit into the foam surrounding you.”

Horrified, the young detective peeled her eyes open, letting the teardrops dry out as she stared at the screen in front of her. It didn’t take long for it to resume playing from exactly where it had left off, the concerning but undeniably sexual images assaulting her senses while the explanation of the ‘service’ continued. The recording kept going, explaining in great detail what had already been told to her more or less by the odd pair, that she was being transferred somewhere to cure her of her suppressed sexual and masochistic desires. There were also some wild reassurances of her safety, as well as the validity of the ‘treatment’ and of their work process. By now, Sienna’s eyes were burning and, although she resisted the need to blink, her muscles eventually relented, shutting down for a brief second. The detective tensed up as she quickly opened her eyes, preparing for another shock. But it never came.

“Now, let me explain some of the features one can experience during their transport.” The voice said after about five minutes of prattling on and on about safety. “The first thing you can experience is what all of our patients crave.”

As the recording continued, Sienna felt the intruders inside of her come to life, slowly picking up in vibration intensity. The way her body was positioned by the foam holding her in place made the dildo in her pussy press up against her G-spot, sending signals to her brain that were almost painful. The bound investigator wanted nothing more than to release some of the quickly building pressure by screaming out, or at least let out a moan or a groan, but nothing could escape her throat, save for a loud, whistling breath. All she managed to do was gag on the bulb that threatened to enter her gullet with even the slightest of movements.

“Of course, there are more than one stages of this stimulation.” The man continued. “You will come to know most of these, as they will alternate to keep you occupied during your experience. And remember! There are no orgasms allowed!”

Just as the voice had stopped, both vibrators began a slow, lazy spin, rubbing against the detective’s insides. At the same time, the metallic round object brushing up against her clit began vibrating, though at a much lower level of intensity. The motion of the vibrator in Sienna’s ass caused spasms of pain to travel up her spine, as it was the first thing to violate her rear entrance, except for the tip of an inquisitive finger once or twice. She wondered how anyone, how any woman with a sane mind could even think about having an orgasm under these conditions, but deep down inside, she felt the pressure build up in her mound. Her suffering was accentuated by a sudden feeling of weightlessness, followed by a heavy thud as the crate jostled. From what she could tell, she’d just been lifted and placed onto something. The subtle vibration that transferred through the edges of the crate let her know she was in fact inside a vehicle.

“The electrodes placed in the box are not only present to deter you, dear patient, from closing your eyes; they can also serve a higher purpose.” The voice in her ears continued, accompanied by the ever present moans of the woman in the video. “Namely, a method we like to call nervostimulosis, patent pending. What does it do you ask? Let us demonstrate.”

Sienna’s fingers pushed against the leather holding them tight in a feeble attempt to escape, while she prepared for whatever would come next. For a time however, the voice stayed silent, and nothing happened. Then Sienna felt her abdomen grow slightly hotter, muscles twitching at random. Something similar to the vibrations of the dildos inside her began spreading, and the detective finally realised that it was electricity, working its way through her still numb system and burning away her paralysis. It didn’t take long, seeing as the chemical was already wearing off, for the current to connect with the metal part vibrating against her clit. The moment it did, Sienna felt her clit start vibrating from the inside. It wasn’t painful, like the shock before; it felt more pleasurable in a weird, disturbing way. It was also incredibly intense, bringing her closer to the edge faster than she’d ever been before. If she weren’t gagged in the most brutal way she could imagine, Sienna was sure she’d be moaning just like the woman in the video. The connotation didn’t bode well for her future.

“Last but not definitely not least,” the ‘doctor’ continued, “there is a feature reserved for the more… well endowed patients. Of course, none are left out of our full-body treatment, but the travel kit does come with some limitations.”

Before the sentence was even finished, Sienna already felt a pressure building near her nipples, along with a whirring sound, similar to that of an electric vacuum. She jerked in her bonds when both her nipples were suddenly pulled forward, sucking them into the small tubes she’d noticed earlier. It was not a painful sensation, but there was certainly a lot of tension. Enough, in fact, for the detective to start feeling her heartbeat right on her nipples. Then, as if the suckling was not enough, she felt something akin to a ring of semi-elastic spikes facing inwards begin to drag itself over her stretched nipples in a spiral pattern. Each spin set her nerve endings on fire, making her nipples almost immediately feel tender.

“Teat sensitivity training is a necessary step to bettering out patients. And your journey in self-healing begins before you even cross our doorstep.” The man finished up the presentation, and Sienna could swear she could hear the sleazy smile on his lips as he spoke the last sentence.

The explanation ended and the volume of the video immediately picked up, filling the private investigator’s ears with a myriad of depraved sounds. She watched as the woman in the video was penetrated with a multitude of instruments, was teased and groped by two pairs of gloved hands, and was brought to climax over and over. Despite her dire situation, Sienna felt her own orgasm build deep down below. She had begun sweating, the foam around her heating up. The twin dildos continued their work inside of her, while the circuit that connected her clit, abdomen and the electrode kept vibrating her from the inside, washing away all traces of the paralytic. It didn’t take long for Sienna to reach the edge of orgasmic bliss. She wasn’t eager to be brought to a climax by the devilish machines, not able to handle the absolute humiliation that that would bring her, but the buildup was inescapable. Of course, as the audio had warned her, no orgasms were allowed. She didn’t yet know what that meant, up until she was ready to succumb to the painful pleasure the machines provided her with.

Another dose of high voltage current was released from all the electrodes surrounding her body, which was greatly assisted by the film of salty sweat covering her skin. Sienna jerked violently, the paralytic apparently having worn off by this point, as pain washed over her body. It hurt most near her mound, the electrodes there already directly connected to her nervous system and, most importantly, the little bundle of nerve endings that controlled her pleasure centre. She actually managed to produce a loud whistling sound this time, simultaneously gagging on the bulb, but not much else to relieve the pain. Her orgasm was pushed back right before it came to fruition, leaving her panting and wanting. She was given a blissful moment of peace, before the machines started working her all over again. The relentless assault on all her sensitive parts continued, breaking only for numerous shocks to be delivered, keeping the detective always close to the edge, but never enough to let her cross it.

The cycle kept going for what felt like hours, a new video of the same subject was loaded in the headset, and the endless hum of the vehicle around her was only building up her anxiety. Wherever Sienna was being taken, it was far away from the docks; probably far away from the city too. She wanted to know the answer, but at the same time dreaded it. If she was taken so far away, even if she did manage to escape, how far could she go while stripped naked, exhausted and without even her phone or keys? A sudden stop let her know she’d be getting her answers sooner rather than later. In the relative silence of the foamed box, Sienna began hearing a low hissing sound. It made no sense, as there was no air tank anywhere for there to be pressure loss. Not any that she could see anyway. The answer to that came in the form of taste, as each inhalation through the tube in her mouth left Sienna with a weirdly medicinal aftertaste. It was too late when the young investigator realised she was being gassed. Not that she could have done anything about it anyway. As if to confirm her conclusion, the video feed and all of the machines working on her body shut down, leaving her in darkness. It didn’t take long after that for her to drift off into nothingness.

____________________________________

Sienna came to her senses with a cold shock, her lips already spread and her lungs emptying out into a scream. Her eyes fluttered open, only to be immediately blinded by the bright white light shining down on her. It took her about a minute to adjust to the brightness. In the meanwhile, she felt cold water dripping from her chest, down to her abdomen and making small rivulets around her thighs. She was standing upright this time, limbs outstretched and held apart in a tight spread eagle, by what felt like hard leather cuffs. Finally able to see, the detective spotted the source of the stream that had splashed her awake. The woman in the fetishized nurse outfit was standing a couple of metres away from her, holding what seemed to be a fire hose, the nozzle dripping down onto the white tile floor. Looking around, the detective saw she was inside what appeared to be a communal shower room, not unlike one found in prisons, although tiled in all white and seeming much more clinical in nature. Sienna also noticed the build-up of grime between the worn out tiles, the rust gathering on the shower heads lining the walls and the lack of lighting for most of the room.

In fact, it seemed like the only part that was still being cared for was the corner she was standing in. A couple of bright LED light stands had been brought in to illuminate her and her surroundings, and what seemed to be a rather new-ish copper tub sat behind the nurse character. What was disturbingly not new however were the O-rings that the chains locked onto her cuffs were attached to. In fact, each shower head seemed to have a foursome just like that around it. Though many of them had been corroded through or were outright missing, hers seemed to have been de-rusted and bolted into the wall anew. The weathered, brown leather cuffs that had been locked onto her wrists and ankles with heavy padlocks reminded Sienna of the restraints she’d seen being used on medical patients in movies and TV. None of all this boded well for her. She wasn’t just dealing with bad guys this time around. The ‘nurse’ and the ‘doctor’ seemed to be way too into the whole treatment shtick for it to be a simple scare tactic.

“Wakey, wakey, detective!” The woman chirped, a smile reaching up to her eyes under her surgical mask. “Too much sleep is bad for you, you know!”

“Wh-what…” Sienna began, but was interrupted by a coughing fit. “What the hell is going on? Who are you people?” She asked, her voice trembling more than she’d like.

“Did you sleep through the whole video explanation too, dummy?” The nurse asked again in the same chipper tone that was quickly getting under Sienna’s skin. “The Doctor is going to take care of your condition, honey. He was paid handsomely to do so by… let’s say a concerned party!”

“A… concerned party? What the fuck are you talking about? What condition!?” Sienna cried out in an anxiety induced spew of questions. “Is this some sort of prank? Who put you up to it!?”

The nurse shook her head in feigned disappointment. “This is exactly why you need treatment, sweetie.”

“Treatment? I don’t need no treatment! What I need is for you people to let me go! Right now!” Sienna tried to sound confident in her demands, but her trembling voice only made her sound pathetic. Tears began streaking down her cheeks. “Please, I don’t know what this is all about… I just want to go home!”

The latex-clad woman approached the young investigator, reaching up with one hand to caress Sienna’s cheek, in what seemed to be a reassuring gesture. She wiped away a tear with her thumb, then slipped the digit behind her mask and right into her pursed lips, suckling and moaning loudly in delight. The wild smile on her face, as if she had just tasted the sweetest thing, sent shivers down the detective’s spine. The nurse dropped the hose, stepping closer to the bound girl, her gloved hands reaching down to grasp at her exposed thighs. She pressed her chest up against Sienna’s breasts, pushing her against the cold wall behind her. Sucking air in through her teeth as if in ecstasy, she dug her fingers into the poor girl’s soft flesh, draggin up from her shapely thighs, over her abdomen and right onto her tits, grabbing each one with enough force to make her victim squeal. Sienna turned her head away, trying to escape the woman’s grip, but her bonds had almost no give.

“You’re not going anywhere, sweetie.” The nurse moaned softly into her ear while kneading her breasts forcefully. “I don’t much care for the ‘Doctor’s’ treatments either. I’m just here to enjoy your suffering. So please, go ahead and cry! It only makes it sweeter for me.”

“You’re insane!” Sienna whispered, not daring to look at the woman’s crazy, piercing amber eyes. “I-I… helped you…”

“Helped me?” The woman giggled, a high pitched noise that made Sienna’s ears hurt. “You only ruined my orgasm! Couldn’t you have taken your time to ‘save’ me? I was so close…”

The woman had continued her harsh fondling while they spoke, but decided to finish her violation by pinching Sienna’s nipples between her thumb and index finger, pulling hard and away, forcing the girl to gasp loudly and step forward onto her toes in an attempt to escape the pain. In obvious delight at the younger woman’s suffering, the nurse kept her there for a few more seconds, before finally letting go. Not missing a beat, she picked up the hose and walked back to where she originally stood.

“Now, it’s time to get you cleaned and presentable for the Doctor.” she said, her voice turning cheerful and irritating once again. “He wants to start you up right away!”

She pulled the handle attached to the nozzle back, releasing a torrent of pressurised, freezing cold water, aimed directly at the young investigator’s chest. The stream struck Sienna squarely on her left tit, actually knocking her back into the wall. The cold shock was so intense that the girl opened her mouth to scream, but her breath was simply stuck in her lungs, as if frozen solid. In needless cruelty, the nurse directed the stream over Sienna’s head, making her swallow a good couple of mouthfuls of water in her frenzied attempt to breathe and move out of the way. Left sputtering and coughing, Sienna could only pull against her bonds uselessly, completely unable to escape the rush of water. She managed to eventually get a breath down to fill her lungs, but it only lasted for a couple of seconds, since she immediately began screaming. The nurse laughed at the girl’s reaction, continuing to direct the pressurised stream all over her body, making wavy patterns outwardly from her torso.

Once Sienna’s normally creamy white skin had turned an angry red from trying to warm up, the nurse turned her attention and subsequently the torrent of water to between the detective’s legs, aiming for her pussy. The sheer amount of force made the girl double over, straining against her bonds, her rear pushed up against the tiles behind her. A deep, pained, continuous groan that slowly raised in volume emanated from Sienna, the sudden overstimulation too much for her to handle. She tried in vain to move her most sensitive area away from the stream by awkwardly shifting and shaking her pelvis, as if dancing a perverted dance, but there was no escape. The deviant woman kept aiming perfectly at Sienna’s crotch, though occasionally she’d snap the nozzle upwards, hitting her chest and face.

After another couple of minutes, the nurse finally squelched the water hose and dropped it onto the ground. Placing both hands on her hips, she walked a sassy walk up to her victim, taking great pride in observing her handiwork. Sienna, still panting and shivering from the torture she’d just been forced to endure, hung in her bonds, teeth chattering and breath trembling. Wet strands of dark blonde hair had stuck to her face, dripping down onto her neck. Water droplets still hung to the girl’s body, giving her skin a shining film under the white lights. The latex-clad woman raised her gloved hands, cusping a breast in each palm, kneading her thumbs over the diamond-hard nipples. The girl detective didn’t look up, but she did swallow a couple of times, before drawing in a shaky breath.

“Wh-why…?” she asked, voice barely audible over the sound of water running down the drain below her feet. “Why do you… what did I ever do to you…?”

“Why?” the nurse asked, cocking her head to the side. “Because I can. Because having my way with innocent young women like you is fun. Because watching the Doctor work is exciting!”

“You… You’re sick…” Sienna whispered meekly.

“Aww. Thanks for noticing!” The nurse said in that same chipper tone.

She let go of Sienna’s right breast, only to dip her hand between her legs, finding the tensed up folds and slipping a finger between them. She giggled as she ran her fingers over the girl’s slit, absolutely delighted to find it wet.

“You’re not that better yourself, eh, detective?” She teased. “Getting excited from a cold shower? That’s the sign of a real masochist right there.”

Sienna’s cheeks, despite being already red from increased blood flow, turned a deeper shade of crimson at the statement. She kept looking away, but dry-swallowed as she tried to think about why that was happening. The nurse did say she’d injected her with an aphrodisiac; but that was probably hours ago now. The woman’s prying fingers finding her clit and slipping in and around it in lazy, circular patterns caused the private investigator to gasp. She clearly knew what she was doing, seeing as in a few mere seconds, Sienna had to actively keep down moans from escaping her lips. The extended denial she’d received during her stay in the box was probably the thing that was coming back to haunt her right now. But she couldn’t admit that to the latex-clad sadist; it felt too close to admitting defeat.

“And here I was, thinking I’d have to get you all excited to confirm the Doctor’s ‘findings’.” The woman said, as her fingers kept teasing around Sienna’s sensitive little nub. “I guess we only have to get your patient uniform ready then.”

Sienna finally looked up, finding the casual way the nurse admitted to manipulating her… partner? quite surprising. And the reference to a ‘uniform’ had her deeply worried. The woman kept teasing her clit for a few more seconds, clearly delighting in the fact that the detective was trying to keep from moaning in pleasure. She was clearly skilled with her fingers and Sienna dreaded the implications that came with that show-off. For now, all she could do was hang on.

____________________________________

A little while later, Sienna found herself walking down the corridors of what seemed to be a mostly abandoned hospital. She wasn’t walking alone, of course, as the nurse was just a couple of steps ahead of her, wielding a flashlight and tugging on a leash; a leash that was connected to the bright orange collar locked around her supple neck. The scenery around them was pulled right out of a horror movie. Vast, dark corridors with yellowed out walls, an endless amount of openings and twists and turns, leading to all sorts of rooms, hallways and dead ends. Most openings would have once had doors separating them, but now all that remained were either empty spaces with rusted, bent hinges, or worn-out, chipped and broken wooden doors, showing some tiny amount of the faded green colour they’d once been painted with. The ceiling panels above were missing, leaving cut wires, hanging cables and broken pipes visible. A lot of them had simply fallen off, breaking into pieces and scattered among the thousand other debris littering the floor. The vinyl flooring itself was scratched and stained, with large flakes of the material flung about carelessly. Wherever this building was, it had been abandoned a long time ago.

The ash-blonde found it difficult to walk among the rubble, which was occasionally piled up in small mounds that she needed to avoid. But that was not the only problem; the nurse had forced her to wear a pair of thigh-high, high-heeled leather boots, which both had a pair of locking belts holding them in place, one just above the knee, the other around the thigh. Both belts were pulled tight, making the flesh around them bulge out slightly, and were locked with tiny padlocks. The ten centimetre heels made balancing especially difficult, and the fact that a pair of leather, chain-linked ankle-cuffs had also been locked on over the boots made it even worse. Sienna was forced to take tiny steps so as to not trip over the hobble, keeping her balance and avoiding rubble, all while practically forced to stand on her toes. She wasn’t used to heels, having rarely worn them before, but there was no choice here. She could either walk, or fall over and hit the ground face first.

The rest of her thighs, as well as her rear had been left bare, the cold air permeating the corridors licking across her naked skin and causing goosebumps to appear. A thin leather belt crossed under her legs, barely wide enough to cover her folds, while also just wide enough to be uncomfortable between her buttocks. The belt connected with yet another item Sienna had been forced to wear; a leather straightjacket, much like the ones used to restrain patients that were of potential harm to themselves or others. There were a couple of major differences however. One, her arms were tied to each other, wrist to elbow behind her back and two, it didn’t cover much of her upper body. In fact, save for a T-shaped strap that passed between her tits, connecting to her collar and wrapping around her slender waist, the only part that covered any skin at all were the sleeves keeping her arms enclosed. The whole ensemble forced the detective to hold an upright position at all times, in order to keep her balance, while also jutting her chest out.

As if that all wasn’t enough, the nurse had also taken the liberty of adding to Sienna’s torment and humiliation. A large plug had been forcefully inserted up her ass, which furthered her already erratic walking pattern, while a vibrating dildo was stuffed in her pussy, both held inside by the aforementioned belt. A pair of clamps adorned her nipples, each equipped with a tiny bell that jingled in tune with all the padlocks that made sure her bondage was inescapable. Her mouth had also not been spared, as Sienna had been forced to accommodate a ball gag that was a tad bit too big for her mouth. Not even five minutes in, her jaw was already in agony. Adding to all that was the fact that most of the gear on her came in an obnoxiously bright orange colour, broken up only by the black leathers, reminiscent of prison outfits. It also seemed to reflect light, like a safety vest would. Sienna guessed it was yet another security measure; she’d be easier to find in these dark corridors if even a small amount of light would make her light up like a depraved christmas tree.

The nurse didn’t speak at all while they walked, only tugging on the leash whenever Sienna would fall behind. She was humming a tune all the while however. They walked up at least a couple of flights of stairs, which left a burning ache in the young investigator’s soles, and after a while, the bound girl had begun believing that the nurse was taking her the long way round to wherever they were heading. Eventually though, they entered a part of the abandoned building that seemed to be rather well-kept. Or restored to a functional percentage. The fact that new doors, all made of heavy plastic and sporting multiple locks, had been installed in this stretch made Sienna’s heart drop even further. With dread rising up her stomach, she followed the nurse into one of the rooms.

____________________________________

A few minutes later, Sienna had been made to sit on a gynaecological chair. Her ankle cuffs had been removed, only for her legs to be forced into the stirrups and bound tightly with worn brown leather straps, similar to the ones used during her ‘shower’. Her collar had been clipped onto a bar on the back, forcing her to stretch herself out on the chair, legs held wide open, and arms resting in a small gap behind her back. Her positioning practically forced her to look down at her own body, especially between her legs. But, that was probably the worst part, because right under where her legs were bound, sat a wheeled metal tray that had a few too many shiny, steel instruments laid on it. The young woman recognised a few of the tools from her visits to real doctors, but others she simply couldn’t wrap her head around. Whatever their use, Sienna dreaded she was about to find out. The nurse had strapped her onto the chair, smiling underneath her mask all the while, before departing.

“The Doctor will be with you shortly,” she had said in that same chipper tone, as if this were a regular hospital.

She’d been left alone since then, shifting uncomfortably under the fluorescent lights that somehow worked; and that had been about ten minutes ago. The detective tried to wrap her head around her situation, but the vibrations of the intruder still inside her made that somewhat difficult. She didn’t recognise the location, not that she had much info on where exactly the abandoned hospital was. Swallowing her rising panic as much as possible, Sienna decided to keep as calm as she could. Sooner or later, a chance for her to escape should present itself. She only hoped that when it did, she would still be in one piece. The thought of what would happen to her sent yet another shiver down her spine. It did her no good to think this way, but she couldn’t help it.

Interrupting her thoughts was the sound of the door unlocking, followed by the ‘doctor’ walking into the room. He still wore the same suit as before, only this time it was covered by a doctor’s robe. He also wore a surgical mask, much like his partner, as well as a headlamp. He smiled and bowed his head slightly towards her, before walking over to a small sink. He pressed the pedal on the floor and Sienna was surprised to see clean water start running. He washed and dried his hands, before putting on a pair of latex gloves. He wheeled a stool over between her legs and took a seat, before cracking his fingers. The door behind him opened again, and in strutted the nurse, holding a clipboard and taking a stand on the left side of the bound girl. Not missing a beat, she reached out with a gloved hand and began fiddling with the clamp holding onto Sienna’s nipple, flicking it around gently. The man reached up and released the belt running underneath her legs. The vibrating dildo slipped out right away, her folds too slippery to ever hold it in on their own. The buttplug however, that stayed in; and neither of them made any move to remove it whatsoever.

“Nurse,” the man finally spoke. “Please note the substantial amount of excitement flowing out of the patient’s vagina.” The woman let go of Sienna’s nipple, jotting something down on her clipboard.

Emphasising his words, the ‘doctor’ ran his fingers down her slit, collecting her excitement in his fingers, bringing up for Sienna to see. As if I can’t feel it myself! the detective thought. Is he really trying to convince me, after literally having me drugged and stuffed with a toy!? Her thoughts must have been reflected in her eyes somewhat, as the man gave her an easy smile under his mask and nodded.

“Do not worry, Miss Cross.” He said. “We’re going to take care of exactly this problem for you. But first, we need to run some tests.”

If that was meant to reassure her, it failed miserably. Sienna shivered at the thought of what kind of tests these people could think of performing on her. It didn’t seem like she’d have to wait long to find out either. She felt fingers prodding and touching all over her crotch, pulling her lower lips apart, running over her urethral opening, pushing back her clitoral hood. The man picked up a measuring instrument, using to find out the circumference of her clit, the opening to her pussy, even the distance between that and her distended rosebud. Her plug was removed unceremoniously, making her jerk and squeal, but neither of them gave her any notice. The doctor was too busy making observations, and the nurse scribbled them down. The measuring tool was forced inside her rear and used to push it apart, prompting a gasp from the bound investigator. Her cheeks grew red from embarrassment and frustration as the pair continued to debase her body so casually.

With the measuring tool left aside, the man pushed a pair of fingers inside of her, scratching lightly against her G-spot and causing a moan to escape her lips before she could choke it down. Even more embarrassingly, the doctor told the nurse to note down her ‘adverse reaction to stimulation’. He then proceeded to prod and push against her inner walls, as if searching for more weak spots. All the erratic movement inside her still very stimulated sex had Sienna choking down another couple of moans, since she was actually getting excited. The aphrodisiac must have not yet fully gone through her system. Or worse yet, she’d been injected with more of it. A glance at the nurse’s wide, beaming eyes told her all she needed to know.

“We’re almost done, Miss Cross.” The man stated, pulling his fingers out of her slowly. “We just need to test out your reactions to certain stimuli.”

Not even allowing her the time to ponder the connotations of his statement, the man picked up a speculum, showing it to the detective before applying a generous amount of lube all over the blades. Sienna knew it would hurt to have that thing inside of her, but she was prepared, having done this in the past. What she didn’t expect however was the way the doctor inserted it; instead of going in vertically and turning it at a 90 degree angle, it was left facing sideways. The bound girl hissed through her gag as the blades opened her up, just enough to allow the man to look and touch as freely as he wanted. Sienna watched in horror as he picked up a steel, tube-like instrument with a curved bulb at one end. The nurse stepped around as well, obviously wanting to have a better look at whatever was going to happen. A glass vial with a clear, viscous fluid was opened and the doctor dipped the bulbous end of the tool inside, picking up a generous amount of it.

“This is a stimulant enhancer,” the doctor explained. “Very potent, especially when absorbed through the mucous membranes. It might seem counter-intuitive, but an increase in the amount of stimulation received will enhance the ability to achieve climax, as well as the duration and intensity of them. Essentially, it will make your orgasms so intense, that you will be satisfied with way less. But we will need to coat you thoroughly and constantly for it to reach its full potential.”

Not giving Sienna enough time to let that sink in, the man slipped the fluid-covered instrument inside of her and began running it against her G-spot. An odd, cooling effect washed over the investigator’s insides, like biting on a breath mint. It wasn’t entirely unpleasant, but it wasn’t comfortable either. The bitter, medicinal odour wafted up to her nostrils, mixed with her own smell. Sienna hated being exposed like this and being experimented on as if she were some animal, but the way she was bound left her with no choice. She could barely flex her thighs and abdomen at this point; not even her toes or fingers, seeing as they were all constrained in leather. The doctor took his time, applying a coating of the stuff all over her insides, but paying most attention to her sweet spot, all the while discussing embarrassing details of her sex with the woman standing next to him.

Using a new instrument of similar make, another dollop of the enhancer was scooped up, and generously applied to Sienna’s clit. First the hood, careful circles drawn around it, the cold steel and fluid warming up from her body heat. Then, the nurse stepped up, pulling the hood back with a couple of fingers, allowing for the man to roll the rod around her exposed clit, making sure to cover every last millimetre of it. Then the instrument was tossed into the kidney dish as well and Sienna let out a sigh of relief, thinking the awkward experience was finally over. When another metallic rod, this one thin and narrow, save for a pill-shaped bulb at the end, was picked up, her whole body grew stiff. The detective’s question was answered when it was also dipped into the bottle of medicine, then brought up between her legs. Surely they wouldn’t… The young woman let out a muffled scream and her whole body jerked violently, but she couldn’t stop the tiny thing invading her urethra.

“Nurse, please hold the patient still.” the man mumbled, slowly teasing the sounding rod around the tiny entrance. “We need complete saturation for this to work, Miss Cross. It might be uncomfortable, but it is for your own good.”

The nurse set the clipboard down, then stepped around the stirrups. Lifting her leg over the bed, she gave the bound girl a clear view of her nearly naked nethers before straddling her belly and plopping down. She hugged both of Sienna’s thighs and gripped them tight, holding them against her body and cutting off the last bit of movement the young detective had. With his ‘patient’ now completely immobilised, the man began wriggling the tiny rod, pushing it ever so slowly inside. Sienna, already grunting from being crushed by the nurse’s weight, now began moaning in pain and discomfort, her whole body shaking in response to this most heinous violation. She begged and cried behind her gag, but neither of the fake medical staff paid her any attention. She was forced to endure the penetration of her peehole, the pill-like bulb reaching deep inside of her, distending the sensitive little tube until it found the area over her G-spot. The doctor then began to spread the enhancer around with slow, methodical spins and thrusts, which made Sienna’s urethra feel like it was burning from the inside. The cooling effect of the minty-like substance didn’t help this feeling at all. But at the very least, it didn’t reach all the way into her bladder, saving her the humiliation of pissing herself in front of the cruel duo.

The excruciating ‘procedure’ finally ended after a few more minutes, leaving Sienna entirely spent, a thick layer of sweat covering her skin where it was naked. She hung her head to the side, fully expecting this to be the end of her torment. The doctor even removed the speculum from her pussy as the nurse stood up, making her believe it. It was a lubed up finger tickling her rosebud that got her to snap to her senses again, her eyes wide in horror. No,no,no,no,no! She moaned out in frustration yet again, but it deterred the man none, as he slipped his finger inside her rear, spreading a generous amount of lube around, before splitting her now slippery ring of muscles with the speculum. A high-pitched squeal emanated from deep within the poor girl, rising in intensity as the speculum was widened, exposing her insides once more.

The next thing she knew, was the nurse sliding her gloved hand over the gag, pinching her nose shut and shushing her with a finger of her other hand. Full-blown panic set in as her breathing was completely cut off, making the young investigator squirm and spasm in her bonds, muscles flexing under her creamy white skin, the bells attached to her nipples ringing softly. The doctor didn’t seem to be bothered, or care, continuing with his ministrations, coating yet another rod with the liquid and spreading it on the walls of her rectum with slow, deliberate movements. The nurse flicked her nose with her free finger, pulling focus on her.

“If you stop screaming, I’ll let you breathe, sweetie.” She said calmly, but gave a squeeze to Sienna’s nose, emphasising her point. “Okay?”

WIth her lungs already burning from the lack of oxygen, Sienna nodded, blinking away the tears that had once again formed on the edges of her eyes. The latex-clad woman waited for another five seconds or so, before finally letting go. The girl detective gasped, sucking in air around the gag and groaning softly as her rear was violated yet again. The nurse slipped her hand lower, clasping softly around Sienna’s collared neck, a warning that she would keep her promise. The bound woman kept as still as possible, allowing the man to finish coating her rectum with the enhancer. It took him quite some time and more than a couple of dollops, but eventually he was satisfied, dropping the tool in the kidney dish and releasing the speculum. Sienna let out a guarded sigh as the cold metal was finally removed from her ass, waiting to see what would follow. Indeed, the man was not done, scooping up yet another dollop of the viscous fluid and smearing it all over her quickly tightening rosebud. No matter his gentle touch, the tender skin ached all the same, causing Sienna to moan out. She was halted, however, by a warning squeeze around her throat.

“There we go, Miss Cross,” the man announced while taking his gloves off. “That should slowly take effect overnight. I will see you in the morning. In the meantime, I have to study your casefile.” He added, picking up the clipboard. “Nurse, please escort our dear patient to her accommodations.”

____________________________________

Having taken another slow, torturous walk through the darkened corridors of the hospital, Sienna was finally led to her ‘room’ by the nurse. Well, it was actually more like a cell than a room. A heavy iron door, in a hallway of heavy iron doors, three flights of stairs down from where they had begun was the entrance leading to it. The latex-clad woman opened the door with a key she’d pulled out of her cleavage. Inside, there was no padding on the wall like Sienna expected. The walls were naked concrete, a single solitary lamp lighting up the interior. The room barely had enough space for a single hospital bed, which came prepared with a set of cuffs and straps to hold her down. A small nightstand was near the bed, as was an IV stand, already holding a couple of bags filled with solutions the detective didn’t want to know about. She froze at the precipice, prompting the nurse to tug harder on the leash. Once, twice, then she placed her fists on her hips and looked at the bound girl disapprovingly.

“Come on in, sugar.” She said, her usually chipper tone coloured with a hint of annoyance. “Don’t make me get the cattle prod.”

Sienna hesitated for a moment more, then took the steps necessary to reach the bedside. At the direction of the nurse, she sat down and laid on her back and arms, allowing for her boots to be taken off. With her legs bared, she then moved to lay down properly, getting each ankle cuffed at the ends of the bed. Pulled up to a sitting position, the woman then released her left arm from the armbinder, only to lock it immediately to the bed cuff. Her other arm followed suit and soon enough, Sienna lay on the bed, tied in a spread eagle position, naked save for her collar and cuffs. She shivered as the film of warm sweat on her recently stripped limbs came into contact with the frigid air. The nurse placed her outfit outside, then returned to tighten every strap over the detective’s body. A pair went over her thighs, keeping her from moving her legs at all. Another pair went over her upper arms, locking them in place. A last pair was tightened over her belly and under her breasts. Sienna tested her ability to move, finding she was practically immobilised yet again. The only thing that moved were the clamps, still attached to her nipples, their bells ringing softly.

“Don’tchu worry, sweetie.” the nurse said as she walked around to the IV stand. “You won’t be goin’ nowhere.”

Procuring a bottle of alcohol and some cotton, the latex-clad woman swiped the inside of Sienna’s elbow clean, before carefully inserting a butterfly needle into her vein. One of the bags on the stand was connected to the drop, clear liquid making its way slowly down to her arm. The nurse then moved her hand towards Sienna’s crotch. Already dreading what that entailed, the young investigator tried to close her legs instinctually, but the straps did their job way too well. Her up until recently virgin asshole was assaulted yet again, this time by a thin, phallic bulb. A pump was connected to it, and soon it was blown up to twice its original size, pushing against her inner walls. The second bag of fluid got a tube connected to it, and Sienna belatedly realised what its intended use was. No sooner was the tube connected to her rear than the liquid began filling up her rectum. Finally, the nurse produced a thin steel rod, a much smaller version of the one used to violate her urethra earlier, but with a thicker bulb at the end. The woman pulled her mask down, suggestively licking the sounding rod, before leaning over. Sienna felt the cold metal pushing against her sensitive peehole a second before it was forced inside her, making her squeal in anguish.

“These will make sure you don’t make a mess during the night, hun.” The woman sang, patting Sienna’s belly. “Hold it in for me, okay? I’ll be back for ya in the mornin’!”

Sienna quickly began sweating bullets, her whole body growing more and more uncomfortable by the second. But the nurse didn’t seem to be done with her just yet. Her clamps were pulled free, causing her to scream behind her gag. Letting her adjust to the blood flow for a second, the woman then began spreading a cool, cream-like substance over them, taking some of the pain away. It was only when the smell reached her nostrils that Sienna realised it was the same stuff that had been smeared all over her nethers. The nurse giggled at her bewildered look, but continued to tease the liquid into her hardened, sensitive nipples..

“The Doctor always forgets the nipples, even though he drones on and on about them!” She exclaimed with excitement. “Little bitches like you never seem to appreciate his work at first, so I take it upon myself to add to his lessons.” She pinched a nipple between her fingers, making Sienna moan out in pain. “And what better way than to make your tits as sensitive as your cunt and asshole? I can torture those as much as I want, and the Doctor will be none the wiser!” She winked.

After taking her time toying with Sienna’s tits, the nurse finally wiped her gloves on the girl’s abdomen, before standing up straight. Checking everything over once more, to make sure the detective indeed wasn’t going anywhere, she procured a small clamp from one of her pockets and held it up for the bound girl to see. It had a small vibe attached to it, which she clicked on, filling the silent room with a soft buzz. Sienna shook her head, begging with her eyes and garbled words, but the nurse was undeterred. She reached down between her legs, pulling the clitoral hood back and exposing the slightly engorged nub. With a wink and a smile, she let the teeth snap onto the sensitive flesh. Sienna howled out in agony, jerking so violently that the bed moved a couple of centimetres off of its place.

“Well, that sure got a reaction!” the nurse laughed. “It’ll help ya keep warm throughout the night. And speaking off…”

She walked back to the IV stand, picking up the bag that led to the drop while fishing out a syringe from her pocket. Squeezing the secondary connector tube, she emptied the contents of the syringe through, letting them mix with the solution inside. Winking at Sienna once more, she left, locking the door behind her, abandoning the young detective to a night of suffering. The sting of the clamp faded soon, aided by the vibrations, as did the uncomfortable feeling in her rear. The rod in her urethra, however, kept reminding her of its presence with each breath, as did the ever growing amount of liquid entering her rectum. In just a few minutes, the bag had emptied and her belly had inflated, reminiscent of a woman in early pregnancy stages. The vibrations, although mild, soon had her juices flowing, despite her general agony, leading the investigator to conclude that the syringe held yet another dose of aphrodisiac.

Sleep came rarely for the bound detective, only lasting a few minutes each time, at best. The combination of the vibrations that were not nearly enough to bring her over the edge, with the discomfort in her warbling guts and her rising need to pee made for a hellish situation, but she could do nothing to change it. Sienna couldn’t even tell what the time was, being locked in a windowless, seemingly sound-dampened room. She could only try to sleep and pass the time, but her dreams were haunted by the acts she’d been forced to endure that day, along with the words of the nurse. I’m just here to enjoy your suffering. Cry… make it sweeter… Tears ran down her cheeks when she was awake, as the situation hit her again and again. Then, other kinds of dreams flooded her mind. Dreams of machines fucking her senseless, dreams of being made to cum by the expert fingers of that man…

____________________________________

The next morning, or at least what Sienna thought was morning, the nurse came back. The sleep deprived detective was untied from the bed, only to have the straightjacket forced onto her arms again. The rest of her outfit was nowhere to be found, and although it relieved Sienna to know that she wouldn’t have to balance on those heels, she immediately began wishing to have them back when she had to step barefoot over the debris in the ruined hallways. She was led to the same bathroom as before, where she was finally allowed to relieve herself when the plugs were removed. Yet another cold shower was followed up by the nurse making her wear the ‘patient’ outfit. A shorter walk, that confirmed her suspicions about being taken the long way round the previous day, ended up with them in the same examination room, the doctor already waiting. The young investigator was treated to one more ‘sensitivity enhancement’ session, as they referred to it. Sienna had found it uncomfortable before, but now it was bordering on excruciating. She imagined it was because none of her orifices were allowed any rest during the night; nor was she for that matter. Panting and already feeling exhausted by the ordeal, Sienna was untied from the chair and made to stand.

“You have performed most excellently, Miss Cross.” the man said, looking at Sienna behind his lowered glasses and over the clipboard. The detective felt a sudden urge to punch his glasses in. “The enhancer seems to be taking effect already, judging by the excitement you’ve shown today. We will continue like this and monitor your improvement. In the meantime, you cannot be permitted to climax whatsoever. But we do need to work on your sensitivity in more ways than one. Nurse, please bring her to the isolation room.”

“Gladly, Doctor!” the dark-haired woman exclaimed with joy. The doctor turned and left the room, leaving Sienna alone with the nurse once again. “Come on, slut,” she said, “let’s continue your tour of the facilities.”

Pulled at the end of the leash, Sienna followed the nurse out of the room and down the hallway. This time, thankfully for her tired toes, the trip only lasted a minute or so. Past another heavy plastic door lay a padded room, reminiscent of the cells they kept the clinically insane in. Although apprehensive, the bound girl walked inside with no hiccups, too scared that the nurse would follow through with her threat from last night. Inside, the room was naked save for the padding lining the walls, a small cabinet and a contraption that hung from the ceiling. Two metallic arms connected to a hexagonal ring via a swivel bar. A spider web-like pattern had been fashioned over the ring using a multitude of ropes. The nurse locked the door behind them, before removing the chain between the detective’s ankles. She made the girl spread her legs while standing with her back against the rope web, then proceeded to tie each ankle to a strand with thick zip-ties. Her calves were tied next, as were her thighs, once right over the knee and once right under her crotch. Her waist was tied to it with a pair of belts, one over her navel, the other over her ribs. Sienna was too tired, too exhausted to fight back, not that she was given much choice.

As soon as the straightjacket was removed and her arms were free, her left wrist was wrenched over a rope with a surprising amount of strength. Secured with a zip-tie as well, her other arm was tied off with little effort on the nurse’s part. Each finger on each hand was also tied down, followed by the elbows and the shoulders. A final belt was fed over her chest, squishing her breasts lightly against the belt on her ribs. Her collar was re-attached so that it would hold onto the ropes, and a pair of ties were used to keep her jaw and forehead bound as well. Sienna was left naked, save for the high-heeled boots, and was literally tied from head to toe. She couldn’t budge a single millimetre from her position. All she could do was follow the nurse with her eyes. It somehow felt worse than being paralyzed, as she could flex her muscles and try to move, but failed to produce any result whatsoever. It was a terrifyingly helpless feeling.

“How’s that, darlin’?” The nurse asked in her usual, cheerful tone as she walked up to Sienna’s front. “Can’t move, right? I bet it feels wonderful to a masochistic bitch like you. And we’re not even at the good part yet.”

The woman reached up, grasping a handful of each exposed tit and kneading the soft flesh with her fingers for a couple of seconds. With a smile and a wink, she pushed and Sienna fell backwards with a scream of fear. The hexagon ring swivelled with her, bringing her to a stop in a horizontal position, leaving her suspended entirely in the air. The latex-clad woman walked slowly around the ring, giggling at the adverse reaction and enjoying the way Sienna’s tits wobbled with each panicked breath. From the cabinet, she produced the same set of goggled and noise-cancelling headphones that the young investigator had worn during her transfer. They were fitted over Sienna’s head, but not set in place completely yet. The why was answered immediately, as the nurse presented her with a pair of inflatable plugs, same as the one she’d gagged on. Using the lubrication that now constantly dripped out of her folds, the nurse forced one plug up her rear, followed by the second one in her pussy right after. Both pumps were squeezed simultaneously, growing bigger and bigger inside her, the soft wall of flesh between them nearly crushed. Only when Sienna gritted her teeth on the gag and groaned out from discomfort did the woman stop pumping.

“These’ll stretch ya out nicely, hun.” she said with amusement. “I’ll be back for ya when it’s dinner time!”

The headset was pulled over her eyes, as were the headphones over her ears, plunging her into a silent darkness again. It only lasted for a few seconds, though, as the screen began playing a recording of a different woman suffering at the hands of the duo. She was subjected to the same procedure as Sienna was, which made her realise her own suffering was probably also being recorded. For whose benefit, other than to show and scare new victims, she couldn’t tell. Maybe that concerned party?

Being suspended in the air while tied to such complete immobilisation, with no way to experience the world around her, no sound, no smell, no vision, not even a draft of air on her naked skin; it made her hyperfocus on the video shown and the sounds that came from it. There was nothing else, save for the feeling of being stuffed like a christmas turkey, which only added to the bizarre feeling of arousal that had begun spilling over her body. Was it the ‘enhancer’ that had finally started to work? Was it the aphrodisiac getting pumped into her veins every so often?

Or perhaps… this was something she did actually want. No! I can’t think like that! Sienna cried to herself. This is how they win. I have to resist this, whatever it is. But to what end? Nobody knew where she was. Perhaps if they’d brought her phone along, someone could have tracked it over the GPS signal. But it had burned, along with everything else she had. Her only real hope was for them to make a mistake. But the nurse was always extremely careful with how she handled the ash-blonde. And the doctor seemed like he actually believed he was helping her. She could try tricking them into believing she was agreeable. But the sadistic bitch wouldn’t believe her, not that easily. There was no real option, but the young investigator refused to give up that easily. There was always hope… right?

____________________________________

Sienna could tell it had been hours by the way her stomach grumbled. Suspended in a world without feeling, she had begun losing her mind in the depravity she was forced to watch. It was only when the fifth, hour-long video in a row finally switched off without warning that she knew she wasn’t alone anymore. As promised, the nurse had appeared once again, this time hopefully to take her somewhere she could eat. Using a pair of safety scissors, the nurse made quick work of all the straps holding her down, before forcing her back into the straightjacket. The overfilled plugs were removed, as were the headset and headphones.

Connected by a leash once more, the pair made their way to something that resembled a cafeteria of sorts. Most of it, like the rest of the building, was destroyed; but there was a little part in the corner that had been properly cleaned. Seated there on the table was the doctor, waiting for them with reading material in hand. Next to his feet lay a silver bowl, filled with some sort of greyish food. Sienna could only guess it was gruel. The nurse led her there and clipped her leash to a bolt on the floor. Her gag was finally removed and Sienna grunted in pain as her jaw was finally allowed to close. She spent the next couple of minutes working it out and appreciating the lack of pressure against her teeth.

“Please, Miss Cross, do not hesitate,” said the man, gesturing to the bowl. ” It may not be much, but I can assure you that it is safe.”

Sienna looked up at the man, disbelief clearly written in her eyes. The minuscule amount of food did not seem like it would be satisfying for her appetite, but it was better than nothing. Unsure of how else to approach this problem, the detective spread her knees under her, lowering her body as much as possible. She would still have to dip her chin in the gruel, but what other option did she have? As humiliating as it was to have her eating on the floor like a dog, it wasn’t the worst thing she’d been put through. Her cheeks flushed with colour as she smeared her face, but at least it tasted good. She could feel two sets of eyes on her as she ate, ogling her naked body. Sooner than she would have liked, the meal was over and she straightened her body, looking at the doctor. The man, not noticing her stare right away, finally lowered his clipboard and gave her a quizzical glance.

“Is there something you would like to say, Miss Cross?” He asked. The nurse made to stand but the doctor stopped her with a wave of his hand. “Are you still hungry?”

“I-I… yeah…” Sienna whispered, looking away. She felt ashamed for having to ask her tormentor for more food, but her stomach growled even harder now that it’d finally gotten something to digest. “Cou-could I please… have more?”

“No,” The man said with a smile, “But I can give you something else instead.”

Pushing his chair back, the man spread his legs and zipped down his pants, pulling out his semi-erect manhood. Out of the corner of her eye, Sienna noticed the nurse settling back into her seat with a big, excited smile, clearly visible despite her mask. She felt her cheeks blush even more and absentmindedly tried to scamper away, but the leash was too tight. She looked away from the man, trying to keep the hardening penis out of her eyesight.

“Aww, she is so bashful!” Chirped the woman. “I love it!”

“Have you not done this before?” The doctor asked, leaning forward. “I can have Mrs Morris demonstr-”

“N-no! No, it’s not… I have done it before…” the young investigator continued, hating herself for being so ashamed of this whole situation. She shouldn’t be the one explaining herself! “Why… I asked for more food…?”

“I can assure you it is a most excellent source of protein.” The man chuckled. “And, as part of your rehabilitation, we must get you accustomed to such acts. It is imperative that you learn how to please others, instead of focusing on yourself. And for an acute case of nymphomania such as yours, this is the most efficient way.”

“You cannot be serious!” Sienna finally spat, her eyes wide with disbelief.

“I would have provided you with a different subject.” the doctor continued without missing a beat. “But we have been short on male patients and donors as of… well, forever.”

Sienna glared at the man, bewildered by his words. She didn’t have any reason to believe that this was a legitimate process, much less so after what the nurse had told her. But how did sucking cock have absolutely anything to do with medicine at all!? She opened her mouth, but before she managed to utter a single word, the nurse, nearly jumping out of her seat, slammed the gag right into her gaping mouth.

“You will not disrespect the Doctor this way, slut.” She growled into Sienna’s ear. Then, unclipping the leash from the floor in one fluid motion, she turned to the man. “I will take Miss Cross back to her quarters, Doctor. I believe she is tired!”

The doctor nodded, zipping up his pants and turning back to his reading material. Sienna was forced out of the cafeteria, anger and hunger churning in her stomach at the same time.

____________________________________

Sienna’s daily life became routine. Every morning, she’d be walked to the showers, forced to take a cold wash, sometimes with soap, most times not, and then she’d be moved to the examination room. There, the doctor and the nurse would use the same methods to ‘enhance’ her sensitivity. The first few times, the whole ordeal would only grow more and more painful. But after a week, the young investigator began to indeed feel more sensitive. Not in a painful way, but more… pleasurably. Whether it was the chemicals they forced on her, or the constant edging and denial she was put through, Sienna couldn’t tell. All she knew was that after ten or so days of this treatment, her pussy would just not stop dripping, not even for a second. Her desire had been growing steadily, as had any hope of rescue declined. After the twentieth, or so, day she lost count, and all hope that this would end in any way other than her accepting her new life.

Sometimes, the pair would leave her in an adjacent room, tied to a similar chair, but with no bottom. Instead of the careful touch of the doctor, she was left to the mercy of machines, most of which only had one purpose. To move and grind and fuck a specific part of her body. They were always left on the lowest setting, never to allow her a climax by accident. But they worked over every orifice of hers relentlessly. It was a whole different thing to be assaulted in this way, her heightened senses going haywire after mere minutes of this treatment. Day by day, she felt herself grow more and more accustomed to these violations. It was deeply unsettling to her just how fast that had begun.

After the enhancement, she’d be moved to the sensory deprivation room, where she’d spend most of her time. Unable to feel anything at all, save for her own orifices expanding under the pressure of the inflatable dildos, played dirty tricks on her mind. Sienna could swear that at times she could feel fingers caressing her body, hot breaths travelling across her navel or her sopping crotch. Sometimes there were teeth and biting, sometimes there were tongues. She’d watch countless women, of all colours, shapes and sizes go through the same ordeal as she was, and wonder if any of them were still here. She’d only ever seen the doctor and the nurse, but they had to be doing something else all day, seeing as they kept leaving her alone. But whenever the nurse came for her, she would examine her own body, and find no trace of any touch, tooth or tongue. Was she losing it?

The cafeteria became yet another place she’d see often. Most of the time, the pair would both be there as she ate, but sometimes, sadly, the doctor would not come. Sienna had given in after the first week of near starvation, and taken the offer. The first time was awkward. She’d never sucked on a dick before, or really seen one up close for that matter. Silicone ones yes, but never a real, flesh and blood one. Her lovers had always been of the female persuasion. The young woman had tried to suck on it like one would on a straw, which left her cheeks in pain for the rest of the night. Having to ask for the man’s cock to suck on was embarrassing enough. Not managing to make him cum with her mouth was even worse. The man had ordered the nurse to give her some pointers after that fiasco of an attempt. Which only meant more night-time activities for the young detective.

Night time was one of the things Sienna dreaded most. With the absence of the doctor, the nurse had free reign to do whatever she wanted. Most nights, that simply meant leaving her with clamps, vibrators, gags and plugs, or a combination of some, even all when she fancied it. With the additional order to give her blowjob advice, oral trials became one more thing the detective had to deal with. Whether it was choking, licking or sucking on a realistic dildo, or having the latex-clad woman smother her with her pussy, rubbing it into her nose until she came, her oral skills developed surprisingly quickly. And what’s worse, she found out she liked performing them too. In the back of her quickly decaying mind, she wondered if the nurse hadn’t just been using more drugs on her, but she didn’t really care anymore. If it meant she could satisfy the man, and gulp on the hot, sticky cum she’d begun to crave, she was fine with it.

But, there were also the nights that the nurse had other ideas. Nights where she led the detective back towards the usual rooms, or even a couple of new ones. A few times, she’d been strapped back into the gynaecological chair, and the nurse had used all the tools to simply torture Sienna to her heart’s content. Inserting other sounds into her urethra, with more or even bigger bulbs, or spreading her with the speculum so much that it would test the elasticity of her orifices. She’d even use the tools to torture all of the areas that the enhancer had been working on, making Sienna scream and howl into her gag for hours. But she never dared to tell the doctor. She was afraid that the man simply wouldn’t believe her, or worse, he wouldn’t care.

She’d even tasted the dreaded cattleprod. On the night Sienna had denied the doctor for a third time, the nurse had strutted off with her in tow, leading her to a new wing of the old building, far and away from their usual trawl. There, she’d stretched the young woman out in a large, soundproofed room, after stripping her naked. Sienna had never seen a cattleprod before, but she had heard of them. The sheer length of the thing, and the frightening, jittery sound it produced scared her way more than the thin, probing rods ever did. She had wondered why the latex-clad woman had taken away her gag at first, but when the first zap danced across her buttocks, she knew the answer. Her scream was deafening, and it could have easily travelled across the whole building, were it not silenced by the walls of the room.

The nurse had taken her fill of sadistic pleasure by torturing her for hours, zapping her, teasing her, even whipping her with a nine-tailed flogger at one point. Sienna must have fainted, because she woke up tied to her bed, hyperventilating from the shock. Searing pain crossed her back, thighs, calves and soles; none had been spared the taste of the whip. She found solace in the fact that the evidence would be irrefutable, that the doctor would finally know. Perhaps he’d bother to stop it. But when the nurse came for her, Sienna could walk just fine. Her back didn’t hurt, not any more than usual. Nor did her legs. Confused, sleep deprived and stimulated nearly out of her mind, the young detective concluded she had been hallucinating the event. But if that was true, just how much of this was real? She never really did find out.

____________________________________

After a couple of months, Sienna was allowed to use the tub instead of being showered. Hot water instead of cold, soaps, oils, conditioners. Her obedience and willingness to participate in all the activities that were ordained had landed her some minor benefits. But even as she lay in the water, soaking and enjoying heat for the first time in a long while, she felt an uncomfortable feeling growing in the back of her head. She caught herself naturally putting her arms behind her back when she was allowed to suck the doctor off without bonds, and walking on her toes when walking to her morning bath without her boots. The more obedience she showed, the more freedom she was granted. But it felt… wrong, somehow. The first night she was allowed to sleep with no bondage, she couldn’t even get a wink of sleep. She longed for the hot, weird, sex-flled dreams she’d started having after her arrival. Each night a different lover, each night a unique experience. Were they really dreams, hallucinations or actual events, she had long since given up on finding out. She merely wanted more.

The month after that, Sienna’s sensitivity was deemed as high as it could reach. Thus began a new cycle of programs for her. The sensory deprivation room, or her meditation chamber, as the ex-detective had begun thinking of it, stayed the same. But her training shifted, to a regiment that better suited her heightened needs. At first, it was the same machines that had been working the enhancer in her, this time cranked to high. She could feel every ridge, every nook and cranny of the life-like dildos that were used. Sienna could feel them rub and poke and grind against her most sensitive spots, with no breaks, no change, no mercy. The words of the doctor rang true in her head then. Back when she had just arrived, from her life before, she would have found this excruciating, inhumane, a cruel torture. But now? Now she only wanted more.

After being denied for months, the first couple of thrusts at full speed and vibrations made her cum the most intense, explosive climax of her life. Before the first orgasm could even subside, a second one was growing in its place. Wave after wave of pleasure washed over Sienna’s entire body. Her muscles clenched and stayed firm; her jaw dropped and couldn’t close up again. Her breath escaped and didn’t return. And her mind; her mind began seeing the truth. This was all she was made for, this was what all the training was for. This immense, unstoppable pleasure knocked on her so hard, she had an out of body experience. Floating above herself, watching the relentless machines work her over and over. Later, she wondered if it was just another hallucination, a way for her mind to cope with the intensity. But, in the end, as had been the trend, she didn’t really care.

The worst and simultaneously best part of her new treatment was when she was being treated with the nervostimulosis machine. Essentially a modified defibrillator, with pads that would be stuck to her lower abdomen, mound and a single clamp that would always be attached to her clit, it would provide a constant stream of electricity straight through her nervous system. It felt so numbingly good, working on her clit and G-spot from the inside. It was by far the most intense sensation, even when compared to stimulation from her enhanced erogenous zones. And the orgasms were pure bliss, since the current would keep stimulating the nerves all the way through the climax, intensifying the feeling to a new apex. Sienna wasn’t aware that she could actually squirt, not before she had had her first orgasm with that machine. She’d seen it in porn before, but never could she have imagined the sheer amount of release she could produce. She quickly understood why all those women in the videos she had watched were being so loud during this treatment. And she quickly understood just how addictive the feeling could be, as she would crave to return to it mere minutes after she was taken away.

____________________________________

Sienna was absentmindedly sucking on the plastic phallus in her mouth, swirling her tongue around it while keeping the pressure on with her lips, just as she had been taught. She’d been relaxing on the web of ropes, suspended high above the world, watching yet another lucky girl like herself undergo the miraculous treatment. She now understood all of the moans of pleasure, the screams, the cries. Because she had passed over to the other side, and had finally seen the truth. She squirmed in her bonds as the woman in the video came, squirting with such pressure that the camera lens got wet and lost focus. A pang of jealousy filled her; she had yet to cum that hard.

When the next video loaded in however, the loose connections in her porn and sex addled brain sparked for a split second. Brief as it was, the spark set off her old intuition, the one that had served her so well, back when she was a private eye. A woman that looked suspiciously like the nurse was the subject of the video this time. Sienna recognized the eyes, those bright amber gems that burned with desire and delight every time the girl suffered. But it wasn’t the fact that the nurse had been through the treatment that made her stop and think, for the first time in a long while. No, it was the location tagged along with a timer on the corner of the screen. Maybelle Psychiatric Clinic. The name scratched at the back of her head. She’d heard it, or rather, read it somewhere before.

A couple of hours later, whilst sucking expertly on the doctor’s real cock this time around, Sienna was still playing around with that thought, that she knew the name from somewhere. She bobbed her head and weaved her tongue, making sure to run it across the underside, before snaking it out to lick at his balls. The man quivered, the telltale sign that he was close. Taking a deep breath, Sienna dove in, taking his whole length down her throat, moving only back and forth enough so that she’d bring him over. He groaned, his palm landing gently on her head as he grabbed ahold of her hair. Knowing all too well what would follow, Sienna choked herself purposefully, taking his hot, sticky load directly down her gullet, staying there long past his final orgasmic spasm.

“You have become quite the expert, Miss Cross.” The Doctor complimented her as she pulled away and swallowed all the remnants of his taste. “I see Mrs Morris taught you well. Perhaps it’s time for you to move on?”

“Doc-doctor,” Sienna coughed, before settling back on her knees. “Doctor, I… I don’t think…”

“What’s wrong?” the man asked, leaning forward with what seemed like genuine concern on his face. “You can talk to me, Sienna.”

“I… want to stay… here. With you.” Sienna finally said, focusing her eyes on his. “I don’t want to go back out there. Not now that I know what… what pleasures can be found.”

The doctor was silent for a moment, his eyes darting between hers. Finally, he blinked the confusion away and leaned back in his chair.

“You are not the first of our patients to ask for a permanent place, Si… Miss Cross.” he finally said, looking past her, towards the rest of the cafeteria. “However, there is only one position that is permanent here, and that is Helena’s… I mean, Mrs Morris’s. All our other patients have left this facility and rejoined society with great success. Mrs Morris keeps contact with all of them, and gives me regular updates.”

“Then… Then perhaps I could stay as a student?” SIenna asked, undeterred by the look on the doctor’s face. “An assistant to your assistant? I can be good with paperwork!”

The man shook his head, a sad expression on his face. “I’m afraid I cannot do that to you, or to Mrs Morris.”

“Ca-can you at least… you know, think about it? Please?” Sienna begged. She would have fallen to her hands as well, were they not tied behind her back.

“I can hold a discussion with Mrs Morris,” he relented. “I’ll see if there’s anything we can do. But I can’t promise anything.”

Sienna nodded, laying her head on his lap happily. Their little sessions in the cafeteria had quickly become her favourite time of the day. In her mind, however, names, locations and their connection swirled, trying to find their right place.

____________________________________

That night, Sienna found herself tightly tied to her bed once more. As per usual, the nurse had tied her arms and legs to the corners of the frame, then had pinned her down with the straps. This time however, her gag had not been replaced, letting her jaw rest. As for the rest, other than the usual plugs and the IV, she’d been left to her own devices. Ever since the first time she’d been allowed to cum by the doctor, Mrs Morris had eased off with the toys that would leave Sienna frustrated.

Put in that unique position for once, Sienna had just enough mental capacity to work out the thing that had been bothering her all day. Maybelle Clinic. She’d read about it in the news, more than once. She pushed and pushed through the haze in her mind, trying to figure out why it was bothering her so much. It must have had something to do with one of her cases. But why did she have two distinct memories of reading about the same place? Squeezing her brain, she managed to remember one more detail, but just enough to set the two memories apart. The first time she’d read about the Clinic, someone infamous had been admitted to it. And the second time…

The door to her room burst open, and Sienna jerked violently, letting out a frightened yelp. Standing in the doorway was the nurse, fury clearly visible on her face behind the mask. She slammed the door shut behind her and walked up to Sienna, a gloved hand gripping her chin forcefully.

“You conniving little bitch!” She spat, her free hand pulling her mask down. “Who do you think you are, huh?”

Sienna tensed up, genuinely afraid from the sudden outburst. Tied the way she was left her entirely unable to defend herself as well. The nurse let her chin go, only to land a backhand against her cheek. The slap knocked Sienna’s head to the side, but it snapped her out of it.

“Wait, wait!” she begged. “Wha-why are you angry?”

“Why am I angry!?” the nurse asked, spittle flying from the force with which she spoke. “You are trying to get rid of me! For a second, fucking time in your miserable life.”

“Se-second time?” Sienna asked, shrinking into the bed as much as she could. “When did I ev-”

A second slap shut her up, followed by a third that made her cry out. The nurse gripped her cheeks with one hand, pushing her fingers in against her teeth, forcing the girl to open her mouth. A ring gag was forced behind her teeth and cruelly tightened until it held her mouth agape by biting into the sides of her lips. The latex-clad woman hopped onto the bed, seating herself high on Sienna’s abdomen, their faces almost touching. Out of her pocket, Sienna noticed the nurse pulling out a two-prong taser. The woman moved her hand behind her back, pushing the metal prongs against Sienna’s navel.

“You don’t remember me, do ya darlin’? Not even after all this time?” She hissed through her teeth. “I don’t know if I should find that insulting or hilarious.”

Sienna glared up at the woman, entirely flabbergasted. The name Morris had reminded her of something way back when she’d first been captured, but she’d never figured it out.

“Your meddling got me arrested a few years ago, you fuckin’ slut.” the nurse explained, fingering the trigger for the taser. Sienna screamed as electricity coursed through her body, but the nurse slipped her middle finger past her teeth, making her gag on her own scream. “You ruined my life!”

She pressed the trigger again and again, shocking the ex-detective all over her body. Sienna squirmed and spasmed under the assault, garbled screams barely escaping the finger choking her. She pulled against her bonds in panic, but they were as tight as always, offering not a single centimetre for her to take. The woman’s anger faded with each scream of her victim, a sadistic grin slowly replacing her frown. Eventually, she’d had enough, placing the prongs up against Sienna’s neck, her finger lingering over the trigger threateningly.

“But I made something out of it anyway.” She finally said. “I took an insanity plea, which landed me in Maybelle…”

It finally clicked. Helena Morris. She was the main suspect of the second case that Sienna had ever worked with, back in her late teens. They’d never met face to face, but the detective had seen a picture or two of her after she’d been arrested. Back when she had opened her first office with her companion and almost fiancee. But that was a different, painful memory altogether. Helena had been engaged in work with a group that would traffic vulnerable women. Sienna had stumbled upon her when investigating a missing girl case for a distressed mother. Her partner had advised her not to take the case, as it was probably just a teenager on a drug bender and wouldn’t have been a good look for their office. But Sienna was never one to turn down a client, especially one that genuinely believed that her daughter hadn’t just run away.

Her investigation led her to many a weird and dangerous places, even getting her captured and interrogated by a pair of sadists, much like the ones that had been her captors for the past few months. Her partner had shown up and rescued her; she’d always been there to save her ass when something like that happened. All of it eventually led her to this one person, Helena Morris. She was the head nurse of a ‘shelter’, a front for the group to exploit those most vulnerable. Sienna, fueled by righteous fury, had brought the police down on the place, getting her and some of her underlings arrested. Later, she came to regret that decision. If she had waited, taken her time to collect information and evidence, she could have dealt a much bigger dent into that operation. The case did bring a lot of light and fame to her office, but Sienna had always felt that it was one of her biggest mistakes. And now here it was, back to bite her in the ass.

“…That’s where I met the good doctor.” The nurse continued to explain. “It didn’t take long for me to convince him that his unorthodox methods were working. And here we are, after all this time. It’s been fun, extracting my revenge on you, Miss Cross. But since you’re trying to blow my cover, I think it’s time I pack up and go. I have made more than enough money thanks to that gullible idiot of a man and all the victims he so graciously provided.”

She clicked the trigger, sending the worst shock yet through Sienna’s jaw, making her teeth chatter against the steel ring. Laughing in sadistic delight, she tossed the taser back onto the bed and pulled a syringe out of her pocket.

“No aphrodisiacs this time, hun.” she said, slowly getting off of Sienna. She reached for the IV bag. “You’re gonna be overdosing on this stuff before the sun’s up. It’s been fun se-ARGHH!!”

The nurse began screaming, the syringe flying out of her grasp as her whole body spasmed violently. Behind her, the doctor had burst into the room, holding her own taser against her back. He fried her long enough for her to keel over, unconscious. He let the taser drop and break on the floor, his eyes wide with a mix of anger and anguish. Looking down at the nurse for a second or two, making sure she was actually out of it, the man then turned to look at Sienna.

“Are you okay, Miss Cross?” He asked, undoing her gag. “Did she hurt you?”

“Ugh, yes, Doctor.” Sienna said, her throat still sore. “Doctor, you need t-”

“Don’t worry.” He said, waving his hand in a calming gesture. “I was on my way to tell you that we perhaps could have worked out your request. I was standing outside and I… I heard everything.” He trailed off, sadness spreading over his face. “I’m sorry. I wasn’t aware of the danger… the danger I was putting you through.”

“Oh… thank god…” Sienna said, breaking down into tears.

“Shh…” The man whispered as he leaned over to hug her. “It’s okay, I got here in time. You’re safe now…”

____________________________________

A few days later, after a couple of lengthy discussions with the doctor, Sienna found herself wearing her usual bondage outfit, but with a new addition. On the belt that crossed between her legs, a new, life-like dildo had been strapped on tight. It was currently plunged to the hilt in the nurse’s quivering flower. Every so often, the ex-detective would pump her hips, giving a tiny bit of stimulation to the woman bound before her. Helena’s arms were extended over a table, tied off to each corner with a pair of leather cuffs. Her legs, similarly, were tied to opposite ends of the same table, leaving her rear and crotch entirely exposed. She was facing down, tits pressed against the cold metal. A soft scraping sound could be heard whenever she moved her upper body, which Sienna knew were the clover clamps the doctor had put on her.

The nurse would occasionally moan or grumble from behind her gag, but the pair had no way of communicating, seeing as they were both gagged. During her discussions with the doctor, Sienna had suggested that they try to get her to spill as much information as possible about her associates and their business. It was probably too late to save any of the other women, but perhaps they could do some damage to the operation with knowledge from the inside. The nurse had refused to tell them anything, of course, but that had deterred the doctor and his new, probationary nurse none. Helena had been put to a regiment much stricter than the one Sienna had been on, constantly being at the whim of the machines in the room next to them, being treated with the same enhancer, or being left at the disposal of the new nurse.

Sienna had taken to her new duties with added gusto, eager to prove herself worthy. She’d been spending most of her non-sleeping time with Helena, giving her a much needed taste of her own medicine. She’d been in constant denial for nearly a week, with almost no rest and non-stop teasing. When it wasn’t Sienna fucking her with a strap on, it was the machines, or an inflatable plug, or a vibrator. Sometimes, they’d even strap her to the nervostimulosis machine, setting it to deny her with a shock whenever she’d get close. Helena had clearly tasted the bliss of that machine, as she would scream the hardest when she was denied from it.

When Sienna wasn’t in charge of Helena, she’d be put through her usual regiment, albeit with lesser hours. And although the doctor was kinder with her nightly treatment than the ex-nurse was, he spared her none during the rest of the day. But Sienna wouldn’t have it any other way. She’d often request to be tied alongside Helena, with both of them suffering the pleasure and attention of the man now completely in charge. Secretly, Sienna also loved to show off the fact that she was allowed to cum to the ever denied ex-nurse, often looking her straight in the eye when climaxing.

It was one such set-up today as well. Both women were bound, and attached to each other. Helena’s hair had been fashioned into a ponytail, a rope looped and fed through it that connected to Sienna’s collar. The doctor had tied them up before leaving them there to stew for a bit in their own juices. He would be coming back to finish the job, but he wasn’t in any kind of hurry. Sienna had spent that time thrusting deep into the woman in front of her at unsuspecting times, or pulling back on her collar, and subsequently on Helena’s hair. She’d never been a particularly vengeful person before, but hearing the ex-nurse scream whenever she tormented her brought her sadistic glee, setting butterflies off in her stomach. After a long while of Sienna tormenting the woman at her mercy, the door finally opened and the man walked in.

“Hello, ladies.” He said with a smile. “Hope you haven’t been waiting long!”

Not expecting a response, he walked right up behind Sienna, unzipping his pants and pulling out his already throbbing hard erection. Sienna couldn’t blame him. The sight of two women bound to each other as they were must have been quite erotic. She wondered how he had resisted just fucking them from the start. That thought vanished as soon as he rubbed his engorged, red-hot glans against her dripping folds. A deep, needy moan escaped her lips as she ground herself against him, trying to get his manhood to slip inside. At the same time, the ex-nurse sprawled on the table groaned in disappointment as the phallus inside her was pulled out. Sienna felt the doctor’s cock twitch as he was met with the chorus of moans. Planting a hand on either of her hips, the man took hold and thrust forward, slamming himself and Sienna’s strap-on home. A trio of moans, each in a different level of pleasure echoed in the room.

The ex-detective arched her back as the man pulled out, keeping her in place while he slammed right back in, her insides so slippery that he almost met no resistance. He was as big as any of the dildos used on her the past months, and even thicker than that. His underside would grind against her sensitive G-spot which each thrust, making her legs quiver below her, threatening to give out. Her first climax came not even a minute in, making her spasm and squirm with the intensity. In the meantime, the bound woman was grinding her own crotch against Sienna’s fake cock, groaning and moaning but clearly not receiving as much stimulation as she craved. Smiling in delight, the ash-blonde pulled back while pushing against the man behind her, before letting her crotch be thrust forward again, plunging the strap-on deep. She was rewarded with a reedy squeal of desire from Helena. Waiting for a couple of thrusts more, Sienna pulled the same move, making the ex-nurse moan again. It was difficult to focus on giving a fraction of the pleasure she was receiving to the woman, but she tried anyway.

Sienna came again, the real, burning hot, flesh and blood cock in her feeling so much better compared to the dildos she was used to. Here and there, despite taking her own pleasure more seriously, she pulled back and gave her rival a taste, just enough to keep her close. The doctor began picking up speed, his twitching cock betraying the arrival of his own climax. Deciding to tease the ex-nurse more, Sienna pulled back once more, but the man shifting his hands to grasp around her chest and hair made her lose her aim. Helena screamed as the strap-on slipped inside her rear, too wet from her excitement to be stopped by the puckered ring of muscles. She thrashed and groaned, but her hair was also being pulled back, just as Sienna was by the doctor, leaving her unable to pull herself away. Grinning with sadistic pleasure, the new nurse pushed forward, letting the thrusts of the man guide her own cock deeper into the woman.

With a growl, the man pushed inside and came, his release spurting deep inside Sienna. At the same time, Helena cried out and tried to scramble more onto the table as the strap-on was buried all the way up her rectum. The way she was bound, it was futile, but Sienna could understand the need to try. The doctor pulled out with a satisfied groan, letting his cum drip onto the floor. He ran his hands over Sienna’s shoulders, who turned around to wink at him. Wordlessly, the man zipped up his pants, smiled and made for the door. The women were clearly not done, and he would let his new nurse have her fun. Now in full control, Sienna pulled back, humming that same tune the woman below her used to hum when she tortured the ex-detective, and thrust back in, eliciting a squeal out of Helena. It would be such a long night for her.

A few weeks later, somewhere else in the city, a video of Sienna suffering in her early stages of training came to an end. The young woman watching pulled her wet fingers out of her pants and smiled with glee. Clicking the X button with her free hand, she navigated out of the ‘PROJECT COMPLETE’ email thread and clicked the ‘Re: Additional services?’ thread. Confirming the address posted, she made her way to the exit of her office, picking up her jacket on the way. WInter had just rolled in, and the docks were cold at this time of night.

Riley Hansen, the best P.I. in town after the disappearance of her old partner, lover and eventual rival, entered the docks. It amused her that the meeting point for this arrangement was the same as the fake info she had fed Sienna almost a year ago. She’d thoroughly enjoyed watching her bitch of an ex suffer at the hands of one of her first bags. The karmic justice alone had kept her high for weeks. And the hours of videos she’d been provided with had kept her satisfied for the past year. But when she received the news that the training was done and that there would be no more updates from Helena, she felt a pang of disappointment that grew with each passing day. Eventually, she decided that she wanted to see just how much Sienna had changed first hand, and no price would be too large. Besides, she had plenty of work now.

The warehouse was dark, prompting Riley to turn on her trusty flashlight. Walking among the scattered crates and containers, the young redhead made her way to the back, where she’d been instructed to meet. A faint, soft buzzing sound, accompanied by soft moans reached her ears the further in she walked. Checking her surroundings to make sure no other people were around, she pressed on. Behind a large container, she came across a sight she definitely wasn’t expecting. A naked, blindfolded, dark-blonde woman was bound to the rafters above with a long strand of rope, her toes barely touching the moist floor. Between her legs, a wand vibrator was buzzing away, making the woman writhe and moan in pleasure behind her gag. Getting over the initial surprise, Riley smiled. She would recognise those moans anywhere.

“Hello, ‘Enna.” she said softly, reaching over to switch off the vibrator. “None of that right now. I don’t want you cumming just yet.”

The naked woman jerked in her bonds, head jolting upwards in surprise, clearly recognising the voice. Riley giggled in delight, watching her rival fight with her bonds. She never saw or heard the man approaching her slowly from the darkness. Nor did she notice the smile spreading across Sienna’s lips.
