Another chapter in Sophie’s search for a new sex improvement drug. With Daniel as her test subject, what will she discover?
SophieTania pulled Sophie into the nearest taxi outside the club and sat down, her beautiful eyes flashing with excitement and expectation. Sophie’s own heart was beating at a thousand miles an hour as she looked back at Tania, not quite knowing how she’d ended up like this but fully enjoying where the night had gone. This was the first time she’d found a girl properly attractive and though Sophie suspected it was something to do with Daniel, she buried that prospect for now.

She gave the taxi driver her address and sat next to Tania with a thump as he pulled away from the club. The two shared a giggle and looked into each other’s eyes, seemingly star struck. Tania placed her coat over their laps and laid a hand on her knee, giving it a small squeeze. Sophie could also feel Tania’s hand rubbing her arm, sending electricity through her entire body and causing a heat to build between her legs. She wanted to be grabbed, handled, she wanted to submit and fully give herself to Tania tonight. As if she sensed this, Tania slid her hand up Sophie’s legs and soon, her fingers were sliding Sophie’s thong to the side and running themselves up and down her pussy.

Sophie let out a small squeal but Tania raised a finger to her lips and looked quickly at the driver. As she began rubbing Sophie’s clit between her fingers, stroking and teasing her, Tania began to talk.

“I didn’t think I’d enjoy tonight as much as I have,” she began, speaking loudly so that the taxi driver could hear. Sophie could see his eyes flick to them in his mirror every now and then and felt a weird thrill every time they did.

“Normally, I just get checked out by guys all night but none of them have the balls to actually take me home. I think they get scared of a girl who gets what she wants, don’t you think?”

Sophie stuttered a reply but couldn’t take her mind off of what Tania was doing to her. She could feel her dress getting soaked with her own juices and was sure it must be leaking through to the seat now. Tania’s fingers were moving in small circles around her clit, occasionally brushing it and sending shocks through her body. Trying to mask her small gasps as hiccoughs, Sophie began to lose herself in Tania’s grasp, hanging onto her breathy words.

“Sometimes a guy just can’t give you what you want, right?” Tania asked, pressing harder against Sophie’s pussy and causing her to dig her nails into the seats. As she focussed once more, she saw that the driver was now looking directly at her, eyes wide. She caught herself smiling at him, biting her lip and knowing that he was now fully erect. Maybe she’d invite him in and let him watch whatever was about to happen. But only if Tania wanted. But maybe Daniel didn’t want that. It was his house, right? Sophie smiled at this. She made a mental note to write down her own psychological changes when exposed to Daniel and his penis.

The car lurched to a stop and Sophie saw that she was outside her own house. Tania loudly thanked the driver before opening the door and stepping out, leaving Sophie to pay him. She bent forward and got her purse out, flipping through the notes she had left.

“How much was it?” Sophie asked, peering through the window.

She could see him grabbing a bit of paper and hastily writing something on it. He turned and she could see his pudgy face looking strained, his chest rising and falling in shallow breaths. Fumbling with the paper, he made eye contact and smiled at her.

“Either £14.50 or you can give me those knickers, luv,” he leered.

Sophie was taken aback by this, not because he was so forward, but because she really wanted to. A thrill ran through her as she hoiked up her dress, pulled her thong down and off her legs, and handed the soaked fabric to the driver. She could smell her own juices on them, which still lingered on her fingers afterwards. The driver scrunched them up and took a deep sniff of them before handing Sophie the piece of paper.

“This is my number if you ever want a taxi ride anywhere. Give me a call and I’ll be more than happy to take you.”

“Oh thank you!” Sophie smiled as she exited the taxi, turning to see Tania already by her front door.

Sophie informed Tania of her new perverted free ride, making Tania grab Sophie by the back of the neck and pull her into a kiss. Tania was a bit taller than Sophie so she had to crane her neck a bit but loved the strong grip on her neck and the feel of her tongue intertwining with her own. She could feel something on it which rubbed the inside of her mouth as Tania’s tongue darted and caressed her own.

“You have a tongue stud?” Sophie asked, after breaking the kiss.

“Enough talk, I need to sit on your face until I cum,” Tania said, making Sophie unlock the door in double time and lead her new experience upstairs.

Daniel

“Ok, get your butt in the air,” Daniel commanded, pulling Yuki up by the hips and giving her arse a nice slap. Yuki cooed as her butt rippled, making her wiggle it a bit more. In the dimmed light, Daniel could see her juices drip down her thigh, mingling with Julie’s saliva after her intensive eat-out session.

“Damn, Julie, you are good at eating out,” Yuki sighed.

Julie could only mumble happily as her mouth was currently filled with Daniel’s thick cock head. She was sucking and licking the last of the cum off his shaft like it was a lollypop, savouring every inch her tongue managed to find. Daniel stroked her luscious hair as he pulled his dick out of her, and smirked as her keen tongue tried to wrap around his cock and keep it close. But Daniel needed it, no matter what a cock-crazed girl wanted. He shifted around and knelt above Julie’s mouth, allowing his balls to brush up against her lips. Instinctively, she began sucking and licking his balls with large slurps whilst her hands slid up and down his spit-lubed dick.

Daniel grabbed a hold of Yuki’s large butt and pulled her cheeks apart, exposing her soaked pussy and tight arsehole. The idea of plunging into her tight arsehole danced across his mind but a more primal urge filled him.

Breed this woman. Fill her with your seed.

With a grunt, Daniel took hold of Yuki by the hips and pulled her towards him, feeling the heat radiate from her pussy. As his dick touched her pussy lips and spread them ever so slightly, Yuki let out a whimper. Daniel stroked her head comfortingly and bent forward so his mouth was next to her ear. His dick slid across her pussy and his balls pulled ever so slightly against the firm sucking sensation of Julie’s wet lips.

“What’s up?” Daniel asked, squeezing Yuki’s shoulder blades with one hand whilst keeping a hand on her hips. Good hips. Wide hips. Hips he couldn’t wait to squeeze as he unloaded his cum into this Japanese beauty.

“Please go slow, you’re very big,” she whimpered, leaning back ever so slightly.

“Oh baby,” Daniel moaned as he began to reposition, “I’m going to use you however I want.”

With that, he let go of her shoulders and guided his dick firmly into her overflowing pussy. Yuki tightened up and squealed as the head of his dick pushed into her wonderful body. Daniel spread her cheeks once more and thrust once more before pulling out. He built up a rhythm, getting deeper with each thrust until he was able to fit two thirds of his tireless dick into Yuki. With each motion, he could feel Julie’s eager tongue lap at his swinging balls, her hands still sliding up and down the base of his cock.

Leaning forward, Daniel grabbed onto Yuki’s boobs, feeling them fill up his palms and shake with the constant motion of his hips. Her nipples were bigger than Julie’s, bigger and thicker; his fingers squeezing and twisting them as he tried to push deeper into her. She was so tight and was clenching with each squeeze he would give to her nipples, making it hard to fill her up with his full cock, but he knew he needed to.

Daniel was losing himself in pleasure. He didn’t know where he’d gotten this energy from but he was infatuated with sex. The feeling of delving deep into Yuki, her excited yelps filling the room, the slurping of Julie trying to tease the cum out of his balls once more. He wanted nothing more than to breed these two gorgeous girls and yet he was still in Uni. He didn’t actually want to breed these two did he? But then he began thinking of their breasts swelling with milk, their bodies becoming rounder and fuller, them giving into him entirely. Who cared if they were getting pregnant? They were his sluts tonight.

Between his legs, he could feel Julie begin playing with Yuki’s clit and now her yelps had become guttural grunts as this asian beauty began pushing her arse back in rhythm with him, trying to get Daniel as deep within her as possible. Soon, his pelvis was slamming into her thick cheeks and Yuki was letting out a constant moan which rose and fell with Daniel’s thrusts. Julie was licking his balls feverishly now, pushing him to the edge.

Cum in her. Make her yours.

Daniel grabbed onto Yuki’s hair and began slamming into her, not caring for anything else other than pleasure. Yuki was screaming now. “Yes! Baby! So fucking big!”

“Cum for me,” Daniel said and pulled her back so that she engulfed his dick. He could feel the orgasm begin to shake Yuki’s thick frame as Julie’s fingers were hurriedly flicking Yuki’s clit and began to unload his cum. Yuki shook and bellowed as her hands collapsed from beneath her, leaving only her arse in the air. Daniel held on and pushed as deep as he could, feeling her tense and spasm around him. She milked his dick with her insides, making stars flash in front of his eyes. She felt so damn good. All he could do was pour more cum into her, breed her, make her his own.

As she began to stop shaking, Daniel picked Yuki’s limp body of the bed and brought her ear close to his mouth once more.

“You feel so fucking good, baby,” he moaned into her ear.

“You feel so good. I can’t believe you feel so good inside me,” Yuki said, her words almost melting in the heat she moment.

“I bet you need a break, huh?”

Yuki hummed a yes as an orgasm aftershock rushed through her body. Julie’s fingers were slowly playing with her clit, it seemed.

“That’s ok, baby, your cum will make great lube for Julie’s titfuck.” With that, Daniel kissed Yuki on the lips, swirling his tongue around her mouth to taste all the juices that had graced it this evening, and pulled out of her.

His still hard cock was now throbbing at the outstretched mouth of Julie. She pushed her large tits together, her cleavage looking unbelievably inviting, and licked her lips. Daniel pushed Yuki to the side and dove in once more.

Sophie

Tania’s fingers were woven through Sophie’s hair and she was holding her lapping tongue against Tania’s clit. She moaned and cooed as Sophie intermingled sucks and licks in with the laps which her lover for tonight seemed to be enjoying. Sophie was enjoying it too. She was a soaked mess, a waterfall in fact, between her thighs. Tania had sat on her face when they had first entered Sophie’s room but had now turned so she was lying on her back and Sophie was lying on her front, her hands spreading Tania’s lips and ever so slightly rubbing them.

So far, Tania had been very domineering; a constant source of dirty talk and moans that detailed exactly what Tania wanted done to her. Sophie was only too happy to oblige. She wanted to please, relishing each orgasm that she brought her lover. As she sent Tania over the edge once again, Tania pulled her up so she could lie beside her before locking lips with her.

The kiss sent shivers through Sophie. It was like touching a live wire. She was truly alive and loving every moment. Sophie wrapped her arms around Tania’s naked and powerful body. Her hands gripped her strong shoulders and ran up into her hair, feeling affectionately stroking it. She felt in love with this girl and yet had only just met her. God damn, everything was so hot. Tania was hot. Her power was hot. The flood between Sophie’s legs was hot. What Tania wanted to do to her was incredibly hot.

Tania broke the kiss. “You’re incredible,” Tania sighed, her accent making her sound cute despite her raw power.

“Just tell me what you want me to do,” Sophie said, her hands beginning to venture down to Tania’s clit once more. As they brushed Tania’s belly button, Sophie felt her wrists being ripped away and pulled far above her head. Tania took a phone charging wire and began tying Sophie’s hands to her bed frame, a big smile on her face.

“I want you to fucking lie there and not cum until I say so,” Tania snarled, finishing the knot and dragging her fingers down Sophie’s body. Gentle strokes soon turned to lustful gropes as Tania tried to caress every part of Sophie’s body. Sophie soon felt Tania’s thin lips latch onto her nipples, nibbling and sucking on them as her hands cupped and squeezed Sophie’s full cups.

“How big are these fat tits?” Tania asked, her tongue lashing the tips of her nipples as her hands ventured further down.

“Thirty-four Double D,” Sophie answered, her breathing becoming heavy. She could feel she was about to cum any second but she needed to hold back, she couldn’t disappoint Tania.

Tania’s fingers began tickling her labia, splitting it apart and grazing the edges of Sophie’s clit. With each touch, Sophie’s body would tense up and shudder, forcing small shrieks to burst from her mouth. Despite Tania’s dirty talk, Sophie didn’t want anyone else in the house to hear Sophie cum. They’d know how submissive she’d become. They’d know her desires. They’d think that they could do the same to Sophie.

Is there anything wrong with that?

Sophie mulled this over for a second before she was ripped away; Tania’s dexterous fingers were beginning to poke into her whilst her thumb played with Sophie’s clit. With her other hand, Tania slid two fingers into Sophie’s mouth, which she sucked and slurped hungrily. As Sophie lapped at her fingers, Tania matched her rhythm and began fingering her, her fingers curling up and stroking her G-spot.

Sophie moaned and sucked harder, hoping to be matched by Tania. She wasn’t disappointed. But she could feel the orgasm quickly approaching. With a panic, she spat out Tania’s fingers from her mouth, and looked at Tania kneeling above her. A lust was burning in her eyes which intensified as Sophie began to helplessly realise that she wouldn’t be able to stop cumming.

“Tania… I’m gonna…”

“I know, honey, cum for me,” Tania growled.

The flood gates opened as pleasure pulsed through her body like a seismic shift.

“Oh thank you! Thank you! Thank you!” Sophie yelled, straining against her restraints as her bottom half writhed around in ecstasy. Sophie’s eyes were clenched so hard that she was beginning to see colours and shapes flash before her. Shocks flooded through her, repeatedly wrecking her body with absolute pleasure. This was all that Sophie ever wanted. She just wanted to cum. She wanted to serve. She wanted Daniel to fuck her. With this realisation, her cunt began to spasm, wishing it was gripping Daniel’s large dick. She loved her creation. With that, Sophie began to black out.

Morning light filled the room as Sophie awoke to movement beside her. As her eyes opened, she saw the gracefully strong form of Tania, wearing only a thong, crouching beside her bed.

“Hey, beautiful, what are these bottles and syringes doing beneath your bed?” Tania asked, holding up an example of each in her hands.

With a shock, Sophie sat up straight and tried to come up with something quick.

“Why were you going through my room?” Sophie finally asked.

“Don’t change the subject, babygirl, what’s with the syringes?” When Tania said babygirl, her heart fluttered slightly.

“Sorry. Ok, just promise you won’t freak out,” Sophie said, defeated.

Tania paused, thought for a moment and nodded approvingly at Sophie. Butterflies were fluttering within Sophie – a whole flock of them. What would Tania say? Sophie wanted to lie but… she couldn’t. Something was making her want to obey her; the same bit that melted when Tania called her babygirl.

“So… I’m currently injecting Daniel full of a drug that’ll make his dick bigger. He’s my guinea pig. I sneak into his room at night and give him his dose.” There was a pause. “Please don’t think I’m weird.”

Tania smiled.

“Oh babygirl, I’m afraid that’s very weird,” Tania moaned, “but it’s also incredibly hot.”
