Carefully, Fiona reached behind her to the edge where the wooden decking met the side of the hot tub which she was relaxing in.
With her fingertips still wet, she scooped her glass into her right hand and took a healthy sip of her white wine before safely returning the drink to its place behind her. With a look of genuine surprise on her face, she called out to her boyfriend who was sat directly across from her. “You haven’t seen her in a whole year? Callum, I know she’s been away studying, but I can’t go more than two weeks without seeing my sister…”
With his back resting against the smooth plastic interior of the hot tub, Callum reached down with his right hand and adjusted the waistband of his black board shorts before looking up to return to her gaze. “Yeah, I mean…it’s not intentional. You know what it’s like, when she moved up north to study…it’s not like we’re in constant contact or anything. We’ve never fallen out, I mean…I can’t even remember the last time we had an argument or a cross word with each other.”
As one of the jets was positioned directly against her lower back, Fiona allowed herself a small groan of pleasure as she felt the tension starting to melt and flow out of her body. Slowly, she extended both of her legs outwards as she leaned back into her position before responding. “Jesus, Callum…she’s only been up in Aberdeen. We’re in Glasgow, it’s not like you’re halfway around the world. You mean to say that you’ve never jumped on a train and went up to see her for a weekend?”
The question hit Callum in such a way that he wasn’t entirely sure how to respond. He and Fiona had only been dating for the last six months, but as they’d grown closer, Callum didn’t want to come across as callous or uncaring when discussing his own family.
As they sat together, relaxing in the hot tub in his parents’ spacious back garden, the sun had yet to set on the warm Thursday evening. It was the first week of June and both were eager to soak up as much of the good weather as they could, knowing that the typical Scottish summer only afforded a few days of sunshine, at best. As Callum pondered Fiona’s question, it was just after 8:00 p.m. and both had been nursing some drinks in the back garden for the past two hours. Both were students who were studying at the same university in Glasgow and the summer break was a welcome opportunity for them to recharge their batteries.
With a tilt of his head, Callum looked up into the sky and paused to take in the view all around him. His eyes glanced towards the thick rectangular wooden beams that stylishly surrounded the hot tub, which were 20-feet long and ran from the base of the brown decking all the way up to meet the structure over their heads. Plenty of sunshine made its way through the huge gaps in the ceiling as all that covered them were matching wooden beams running across the top, which met the side of the house just under the guttering. The hot tub itself was built into the decking and was the centrepiece of the back garden, with enough room for at least 12 people, and both he and Fiona were planning on spending as many of their summer nights using it as their schedules would allow.
After taking a deep breath and allowing himself to slowly exhale, Callum absently puffed out his cheeks and looked Fiona in the eye. “No, I guess…we’re just not that close. It’s hard to put my finger on it, I suppose we’re just comfortable being apart from each other. But there’s definitely no bad blood or simmering resentments. You’ll see that when she gets here, if anything…she’s kind of…unique? Honestly, babe…she’s one of the friendliest people you’ll ever meet. I could sit here all night and try to describe her and not get close.”
As Callum turned and reached behind him to take a sip of his vodka and coke, Fiona slowly ran her right hand through her damp hair and looked across at him. Dressed in just his board shorts, the sight of his firm abdominal muscles rising above the surface of the water reminded Fiona of the immediate attraction she felt towards him on the night they met. While it took her a few months to honestly lay claim to have gotten to know him, it took her all of five seconds, if that, to realise that she wanted him once he literally bumped into her in a club in the city.
Standing just over 6’1″ tall, there wasn’t an ounce of excess fat on Callum’s frame. He was lean, but his muscles were taut from all the hours he spent in the gym. In that moment, Fiona caught herself daydreaming about the first time she saw him with his shirt off, with his strong arms and shoulders ready to swoop in and lift her clean off her feet. But it was his pretty face that always managed to charm her, with his strong jaw and piercing blue eyes that made her feel like that she was his whole world whenever he gave her a certain look. Meanwhile, as he sipped his drink, the dampness in his hair didn’t ruin its style with the back and sides shaved in really closely, with a long dark brown fringe pleasingly swept back and to the side. To her friends, Fiona’s relationship with Callum was the source of considerable jealousy, and he was all hers.
Cautiously, Fiona tilted her right eyebrow as she let her legs extend back out in front of her once more. “You don’t need to tell me about how friendly she is, I’ve seen her Instagram account. Popular would be the word I’d use to describe her, for a random girl studying up in the north of Scotland…she’s…pretty fucking popular. She’s got nearly 50,000 followers and I’m pretty sure more than half of them couldn’t even point to Aberdeen on the map! Listen, I’m sure she must’ve spoken to your mum about getting her boobs done, but did she reach out to you…even as a heads up…to say that she was doing it?”
All Callum could do was offer the same default reaction to whenever anyone brought up his sister’s cosmetic procedure in conversation. He took a deep breath, shrugged his shoulders and exhaled while he searched for the most neutral language his brain could muster. “No, no… She definitely didn’t consult me at all. I mean…how awkward would that conversation have been? I’m pretty sure the last two people on the planet she would’ve talked to about it would’ve been my dad and I. But that’s the thing, babe…she’s never been shy about anything. I can’t bring myself to go on her Instagram page, but I have to hear about it every time I go on a night out. Every time her name comes up, my mates never shut up about her. And that was before the boob job…now I get an almost daily report from the boys about how much they adore her.”
His sister had only been the topic of conversation for over a minute, but it was the most detail Callum had ever went into when discussing her with anyone. While he and Fiona were both 21, his sister was a year older and about to start her final year at university. But while Callum was honest about getting along with his sister, the minute he heard about her surgical enhancements he knew that things would never be quite the same again. In truth, it was because even he knew that his sister looked absolutely sensational. It was his mother that had mentioned his sister’s procedure to him in the kitchen one day, the previous summer, and his mind instantly went into overdrive…predicting the reaction of his friends when they heard that his gorgeous sister was getting an expensive upgrade.
And it was for that reason that he’d been wrestling with the truth ever since. Was he hiding from her? In his own mind, he caught himself wondering if he was starting to become annoyed at her because of the lurid comments his friends, and complete strangers on social media, were making about her body. Each time he found himself in that mental place, he’d chastise himself as he knew his sister was free to make whatever choices she wished. But it left him feeling like he was in an uncomfortable position through no fault of his own.
The discomfort was written all over Callum’s face as he offered his response, which Fiona detected immediately. Slowly, Fiona stood to her feet to stretch her legs and looked down into his blue eyes. “I don’t know…I’m just thinking about what it must be like for a brother in that situation. All of a sudden, your sister’s flaunting her new assets on Instagram and there are guys from all over the world showering her with likes and comments. I don’t suppose that’s going to be a situation that you’ll ever become completely accustomed to. That said, babe…she’s your sister and she’s going to arrive any minute. Try and take the positives from the next two weeks…your parents are away on holiday and you’ll have plenty of time to reconnect with her. I guess what I’m trying to say is…don’t let a bunch of horny guys ruin your relationship with your family. You only get one family, Callum…”
Slowly, he lifted both arms and draped them over the edge of the hot tub behind him. Once Fiona stood from the water, he was treated to a clear view of her pristine bikini body as droplets of water ran down her flat stomach and upper thighs. She was significantly shorter than he was, standing only 5’3″, and the frame of her upper body was incredibly slim. As she stood before him, she was clad in an elegant navy-blue bikini top, sporting cute white polka dots, with a tight halter neck that helped the top cling to her chest. The close fit helped lift her smaller bust, but the top offered plenty of coverage with only the faintest hint of cleavage on display. Despite the cuteness of her bikini, Fiona had never been thrilled by her inability to fill her bikini top in the manner that most guys she met had truly wanted.
But Fiona didn’t lack confidence as she knew that she looked good. With long dark hair that flowed down her back to just above her pert backside, her deep brown eyes and gorgeous smile almost entranced Callum the first time they met. Her skin was soft and lightly tanned, but when she spun around to reach for her drink, Callum got a clear view of her tight cheeks and generously muscular thighs that were her signature features. Before long, Fiona wriggled her hips and sat back down with the jet positioned against her lower back once more.
Before long, a wry smile appeared on Callum’s face as he sought to change the subject from his sister’s body. “Oh, it’ll be fine, babe. She’s staying until a week on Wednesday and my mum and dad get back from Spain the next day. I don’t know what her plans are for when she’s here, but I’m sure she’ll want us to go for lunch or maybe go shopping. That is, if she can drag me out of this hot tub…if it was up to me, I’d be spending every minute in here for the next two weeks.” With his fingertips tapping against the edge of his glass, he looked across to catch Fiona’s gaze. “She sent me a text earlier saying she’d arrive around 7:00 p.m., so she must be running late. Either way, she’ll see us out here when she arrives…”
The next hour passed with Callum and Fiona sipping their cold drinks and enjoying their music as the sun prepared itself to set. It was just after 9:00 p.m. when the two were sitting next to each other, directly facing the back entrance to the family home. Fiona was holding her phone in her right hand as she was showing him a popular post on TikTok that had her giggling and smiling. It was at that point that Callum heard a faint noise from inside the house, which struck him as coming from close to the sliding doors that opened out onto the decking.
He didn’t think too much of it, besides the fact that his sister must’ve finally arrived. Callum glanced up and took a quick peek at the house, but couldn’t see any sign of anyone. The back entrance to the house was comprised of two glass sliding doors sporting a thin white wooden trim, with two full-length glass windows on either side. While it looked fabulous to the neighbours, it afforded Callum a clear view of who was in the kitchen and he couldn’t see anyone. But it did prompt him to start thinking about what he’d say to introduce his girlfriend to his sister, as the moment was fast approaching.
After another few minutes of laughing with Fiona at the different videos she was showing him, Callum’s focus was immediately grabbed by the sound of the back door being slowly slid open. Both he and Fiona had plenty of time to turn their heads and look towards the door in unison, but the sight of what crept out onto the decking threatened to shatter Callum’s mind into a million pieces.
Out onto the decking strode Libby, Callum’s sister, with her new assets poured into a tiny black string bikini top that was clearly outmatched. The thin black straps were pulled up and tied around the base of her neck, tightening the garment around her sensational chest and helping her breasts spill out from all conceivable angles. Callum simply hadn’t ever seen a cleavage like it in person, with the top looking like it was plucked from Libby’s wardrobe from the days before her procedure. The way the thin fabric of the cups rode up her chest was mesmeric as a healthy view of the bottom of her breasts was visible from under the top, and every tiny movement she made caused the most compelling rippling and jiggling across her chest.
Libby stood a few inches taller than Fiona, at 5’7″, and her long red hair was perfectly straightened which reached midway down her back. Callum had been so used to seeing her with much paler skin, but her body showed off a healthy colour that suggested she’d recently been away soaking up the sun or had been for a quality spray tan. As Libby took another step forward, her tight denim shorts were left completely unbuttoned as the thin black waistband of her bikini bottoms was clearly visible, with the waistband riding up over her hips in line with her navel. Libby’s stomach was toned and flat and her thighs were testing the tight denim that rode so far up them. Meanwhile, as she moved forward, Libby’s left hand was clutching her phone while her right hand was taking care not to spill her drink, which was holding about as much white wine as it could reasonably be expected to. With care, Libby took another few steps, barefoot, until she was standing almost directly across from them at the edge of the decking.
For the first few seconds after Libby’s emergence, Callum’s jaw hung wide open until every alarm in his mind screamed out to him in desperation to compose himself. He knew it was his sister, undeniably, but so much of him felt like he was looking at her for the first time. It was as if she’d been completely transformed, all as the result of the heaving breasts that she was showing off without a care in the world. Callum knew that she’d always been pretty, but her entire aura was overwhelming him in that one moment. It felt to him like every single one of her stunning features were being complimented and accentuated to the fullest by what lay beneath her skimpy bikini top.
After having crept towards the edge of the hot tub, the redhead finally directed her attention towards the couple who were sat across from her. With a look down at Fiona from her standing position, Libby spoke up. “It’s so nice to finally meet you, I never usually get to hear anything about what Callum gets up to anymore. I’m Libby, and you must be Fiona? Mum’s been the one that told me all about you, trying to get information out of him these days can be like getting blood from a stone…” As she finished her thought, Libby knelt down to place her wine glass and her phone at the edge of the decking, before taking extra care to ensure that her phone wasn’t in danger of falling into the water.
As Fiona sat next to Callum, she sucked down a deep breath as she watched Libby’s bikini top cling on for dear life. She’d taken some time to look at her Instagram profile and knew, to some degree, what was coming, but seeing Libby in the flesh was something she simply wasn’t prepared for. There was a confidence exuding from her that Fiona had never encountered before. To wear an outfit as revealing as that, while having the body and looks to back it up, almost had Fiona shaking her head in disbelief.
Slowly, Fiona stood up in the hot tub to try to better meet Libby’s gaze. Once she did, she marvelled at Libby’s hazel eyes and responded. “Yeah, I’m Fiona…it’s so lovely to meet you. Callum’s been telling me all about you, studying up in Aberdeen? Did you have a nice journey down? Hopefully it didn’t take too long…”
Once Libby had rested both her drink and her phone on the decking, she stood back up and placed her hands on her hips before looking into Fiona’s eyes. “Three and a half hours on a train, then a taxi from the train station to get here. I swear to God, once I saw that you two were out here in the hot tub, I just threw this on and poured myself a drink… Hopefully you two don’t mind if I join you for a while? My whole body is actually aching after sitting on that train…”
Without waiting for a response, Libby took a firm grip of her tight denim shorts with both hands and started wrestling them off her hips and down past her thighs. It took considerable effort for Libby to accomplish the feat, but Callum sat there almost hypnotised by the way her tits were rippling and bouncing with every ounce of effort she was displaying. Once she kicked the shorts to the side, Callum leaned back against the plastic interior of the hot tub as her bikini bottoms were fully revealed. He knew from all his time checking out the world’s hottest models online that there were bikinis that were simply too indecent to be worn in public. As his eyes stared at the tiny piece of black fabric that covered his sister’s groin, he recognised the small designer logo in the shape of a simple white cross that confirmed to him that Libby was wearing exactly that type of bikini…and she was wearing the hell out of it.
After holding his breath for a few seconds to come to terms with the moment, Callum slowly stood up and looked across to Libby. In that instant, he felt his mind being pulled in so many directions at once. He’d heard the expression of an elephant being in the room, but in this scenario, the elephant was firmly attached to his sister’s chest and Callum had no idea how to proceed. If he brought it up himself, it might come across as weird, whereas if he attempted to play dumb…he was running the same risk.
With only a few seconds to form a plan for the evening, he reverted to his trusted default strategy whenever Libby’s name came up with his friends. He’d be as careful and non-committal as possible. With a look into her eyes, he actually had to steady his nerve to stop his gaze from wandering back down to her chest. “There she is…it’s good to see you, Libby. It’s been a long time, feel free to jump in. We were going to go out later, but once we sat down out here…we just decided that we’d chill and have a few drinks instead. There’s plenty of food and drink in the kitchen, Mum and Dad went overboard knowing we’d be here on our own for two weeks.”
Carefully, Libby tiptoed down the three steps into the hot tub and remained standing across from the couple. When she felt the warm water reach up to her waist, Libby let out a soft groan as she knew how much she’d been looking forward to her journey ending and having the opportunity to relax. Slowly, Libby dropped her hips and sat with her back against the side of the hot tub directly facing Callum and Fiona, with her glass of white wine sitting just behind her right shoulder.
Once she was settled, Libby lifted her head and tried to suppress a soft smirk that had been threatening to creep onto her face. With the couple still on their feet, Libby took a long hard look at her brother for the first time in over a year. While he hadn’t underwent a transformation as dramatic as her own, a small gasp of air escaped past Libby’s plump lips as she appreciated the sight of his shirtless upper body. The difference in his shoulders and upper arms was as clear as day as she admired how strong he looked, like he was finally beginning to fill out his frame as he moved into his early twenties. But the sight of his pronounced abdominal muscles, with beads of water running down his midsection, was taking her back to all those nights she spent alone in her bedroom…thinking about just how badly she wanted to let her tongue roll all over his hard body…
It was for that reason that Libby wasn’t happy at all with Callum’s recent attempts at staying out of her way. Like him, she knew there was no feud or disagreement that was preventing them from seeing each other, but she was nobody’s fool. She knew that as soon as his friends starting liking all of her Instagram pictures, with her new chest pouring out of a parade of gorgeous tight outfits, the lines of communication between the two immediately went dead. It was a consequence of her glamourous makeover that she’d foreseen, but she was taken aback at just how determined Callum had been to keep his distance. Every time she’d met up with her parents over the last year, Callum always had a flimsy excuse not to attend.
But when she let her gaze roam upwards from his body to stare into his pretty blue eyes, there was no shame at all in Libby’s mind about the way her body reacted. The same spark of excitement went off in her chest as it always had from before she moved out of the family home. Callum was her little brother, but as she sat there, across from him in the hot tub, she knew without a shadow of a doubt that he’d never looked better. It had never mattered to Libby whether she was seeing someone or not in her own personal life…she always found the time to think long and hard about Callum while she was playing with her pussy…
A few years earlier, she was still at the stage where she’d convinced herself that what she was doing was wrong. But the distance between them over the last year only fuelled her fantasies and she knew that if there was any sign of weakness on his part…she’d pounce on him before he could think straight.
Still standing, Fiona let her right hand drop down and adjust the waistband of her bikini bottoms before she looked down at Libby. “Listen, Libby…I saw some of your pictures on Instagram over the last few days. I mean, I still can’t believe how good you looked in them. But meeting you for the first time and seeing you in person…you look absolutely incredible…” After a quick glance at Callum, Fiona looked back down into Libby’s eyes. “I think you two need to thank your mum and dad for the genetics they’ve blessed you both with…”
Slowly, Libby’s arms stretched out to run along the back edge of the hot tub behind her. As she did, the impact on her chest was a sight to see as her breasts lifted up and placed even more strain on the thin black fabric of her bikini top. After taking a moment to flash Fiona a smile out of courtesy, Libby took all of three seconds to make her mind up about the girl that her cherished little brother had been dating.
There was no denying that Fiona was an attractive girl, with her long dark hair and tight little ass, but Libby didn’t sense that Fiona’s body would present a credible threat to what she had planned for Callum. Libby knew what his tastes were like when he was growing up, with his bedroom walls plastered with his favourite sex symbols. Only, there were no girls on Callum’s walls with a chest like Fiona’s. Instead, it was a who’s who of voluptuous glamour models with sensational tits that were capable of entrancing any man who gazed upon them. Libby knew she’d never forget the two vintage posters he had of Lucy Pinder and Carmen Electra, with their curves bursting out of the most exquisite black lingerie, that even Libby herself had spent plenty of time pleasuring herself in front of. To Libby, Callum’s posters were like a gateway into his mind to understand what he liked…and from the very minute her own surgery had healed…Libby desperately wanted to show off her new curves for him.
With a soft tilt of her head, Libby appreciated Fiona’s lithe bikini body and her mind started to race. For the whole train journey down, Libby dreamt up various scenarios where she’d be able to ensure that she and Callum would have plenty of time on their own to get reacquainted. The one thing she wasn’t prepared to accept was being a third wheel for Fiona to stay over every night and ride Callum’s dick while she slept alone in the next room. As the train got closer and closer to Glasgow, Libby reached the only conclusion that made sense to her. If she wanted to take Fiona off the board, she’d have to take an appropriate course of action. As the smirk finally made its way onto her face, Libby knew that she had just the trick up her sleeve to take care of her…
Together, the three got comfortable and finished breaking the ice with one another. The next hour flew by as the pace of their drinking quickened and the speaker started playing one of Libby’s favourite house music playlists at a slightly louder volume without being a nuisance to the neighbours. It was just after 10:00 p.m. when the sun had finally set and the lights surrounding the decking illuminated the hot tub delightfully.
Callum had managed to get himself back under control once the shock finally dissipated from seeing his sister’s new enhancements in person for the first time. Despite her lounging against the hot tub directly across from him looking like a world-class influencer, Callum was well on the way to enjoying his evening. He actually took heart from the fact that the worst part was over, seeing her in the flesh not knowing what his reaction was going to be. And while he and Fiona listened to her go through her repertoire of stories, all the best parts of Libby were coming to the fore. He remembered how funny and silly she could be, and she always knew how to make him laugh. Even when she was discussing subjects that were a little personal…
As Libby reached the end of her latest story, she took a long sip of wine from her glass and returned it to the decking over her right shoulder. Slowly, she turned back around and looked Callum in the eye. “Honestly, that’s the last time I’m ever going to try and save money on colouring my hair. I’d already noticed some yellow smearing on the straps of my gorgeous little black dress from when I was in the bathroom earlier that night. Now, if I was sober, I’d have known that something wasn’t right…but I was more than a bit tipsy by the time the cute guy finally started talking to me at the bar. To be fair to him though, he wasn’t capable of looking at my shoulders when I had my cleavage practically under my chin… I don’t think he looked at my face for the first couple of minutes…”
With a slow tilt of her head, Libby caught Fiona’s gaze before continuing. “Getting him home with me was the easy part…but from there I had the worst idea that I’ve ever come up with… For whatever reason, I decided that I wanted him to fuck me in the shower… Now, picture the scene, he peels my tight little dress off and the water’s running…and I think I’m starring in some kind of steamy Hollywood movie. I’m drunk and think that I can do no wrong. Anyway, I pull him into the shower in my flat and it’s absolutely tiny. I’m telling you both, you couldn’t swing a cat inside it…but I’m thinking that I’m about to have the most glamourous sex anyone’s ever had…” Just then, Libby slowly, methodically turned her head until she was staring Callum dead in the eye. “Once we got going, I swear…I’d barely touched him and he was already so fucking hard for me…”
The comment hung in the air until Libby was satisfied that it swam inside her brother’s ear and made a home for itself right between his eyes. Only then did Libby offer a playful giggle to disarm the tension and continue her story. With haste, Libby glanced back at Fiona and continued. “So, the water’s running to the side of us and he’s kissing me like he wants to worship me. I kind of drunkenly whispered to him to pick me up, which he did…and I wrapped my legs around his waist. Then he slammed me back against the shower cubicle wall and I felt the warm stream of water on the top of my head. Now, let me assure you both…I was enjoying myself thoroughly and was waiting for the very glamorous sex to start. I could feel his lips and his tongue all over my chest, but the next thing I know he starts gagging…”
With a wicked look on her face, Libby continued. “Well, wouldn’t you know it…but the thick blonde streaks in my hair started running and it was all over my cheeks, my neck…and my tits… The guy had slurped a little of it down and when he realised what it was, he sat me down and stumbled out of the shower. I swear, his dick was still so fucking hard and he started vomiting into the toilet… It was the most ludicrous sight…” Satisfied that she’d reached the end of her story, Libby offered a warm laugh which prompted the couple across from her to do the same, before she continued. “All the while he was trying to apologise and assure me that he’d be ready to fuck me once he was done, but my dreams of glamorous Hollywood sex were literally flushed down the toilet… So, no more cheap hair dye for me on a night out…”
The level of detail that Libby went into had Fiona’s head spinning. Not only was she a stranger who Libby had only met an hour ago, but Fiona couldn’t understand how Libby could be so comfortable talking about her sex life in front of her brother. But it was in that moment that she started to understand Callum’s description of her from earlier. She was just as friendly, bubbly and fun as he’d suggested…but she was so fucking sexy. Fiona felt that the story she just told would’ve been ridiculous coming out of anyone else’s mouth, but when every word slipped past her pillowy lips with that mischievous tone…Fiona knew that was exactly the kind of scenario that a girl with a body and attitude like that would end up embroiled in.
However, the hair dye and the humour never made it into Fiona’s consciousness…only the key parts of the story did. The implausibly tight black dress. The spellbinding cleavage. The willingness to take a stranger home and fuck him in the shower… The willingness to talk about it to them both while wearing a bikini top that was nowhere near big enough…
Just as those details hammered themselves into Fiona’s mind, she couldn’t stop her gaze from dropping back down to lock themselves onto Libby’s chest. As soon as she did, Fiona felt a rush between her legs as her own nipples started to stiffen. She could’ve counted on one hand the number of times she’d felt sexually attracted to another woman, but what she was feeling in that moment was a breathlessness that only came from being in close proximity to a perfect ten. Libby didn’t just have the body and the pretty face, but she wielded an attitude that she was so proud of being so naughty… At that precise moment, Fiona thanked the heavens that Callum was her brother…because she was absolutely convinced that no man would be able to break free from under Libby’s spell.
As Fiona brought herself together, she didn’t have time to anticipate what kind of response Callum could offer to such a heated story. Slowly, she turned to face him as he leaned forward and called across the short gap to Libby. “Oh my God…how do you keep ending up in those situations? The guy was probably so drunk, I mean…who’d have a reaction like that to a bit of hair dye? Mind you, Libby…you can’t rule out the possibility that your body just repulsed him.”
The smile on Libby’s face was beaming as Fiona watched her stare into her brother’s eyes before she playfully kicked some water at him. At that point, Libby leaned forward with her eyes wide and giggled at Callum, before speaking up. “Oh, you know it was his loss… Don’t worry, Callum, I know that you think your big sister is beautiful. We can’t have Fiona thinking that you’re always so mean to me…” With her grin widening, Libby caught herself glancing at his bare chest before looking back to return his gaze. “Now that we’re reunited, why don’t you just tell me how beautiful you think I am? Go on, Callum…show Fiona how mature you are and how much you’ve grown. Tell your sister how beautiful she is…”
While the comments were so obviously made in jest, Callum slowly stood to his feet and smiled at Libby before walking to the steps and climbing back out onto the decking. After turning back to face the two girls, he called out. “Libby, you’re so fucking embarrassing at times…honest to God!” After shaking his head to deal with the involuntary blushing of his cheeks, Callum glanced towards the back door and continued. “I’ll be about five minutes, just going to grab us some more drinks and I’m absolutely starving. There’s some chicken in the fridge that I’m just going to pick at, I won’t be long.”
With that, Callum walked across the decking towards the back door which led directly into the kitchen. Before he made it even halfway there, Libby let out an exaggerated laugh at his refusal to comply with her request. With a turn of her head, Libby looked across to Fiona and smiled. “Isn’t he just the cutest when he gets embarrassed? Oh, the fun I’ve had over the years teasing him like that. It’s amazing that his little cheeks still get so red after all these years.”
For her part, Fiona felt like she was offered a glimpse through a window into the dynamics of their relationship. It appeared to her that Libby was very much the big sister who didn’t really have any boundaries in terms of what they talked about. But it was clear to Fiona that Libby didn’t just like to talk about sex. It simply radiated from her in a manner that almost any conversation would, inevitably, be dragged back to a sexual nature whenever it pleased her. And all the while, her boyfriend had to endure it despite his clear and obvious discomfort. The reality then presented itself to her that if she was this open with her own brother about her sex life, the chances were that she was even more direct with people that weren’t her blood relative. For instance, Callum’s friends… Immediately, Fiona took a deep breath and understood, for the first time, why he’d want to keep his beautiful sister at arm’s length.
As Callum disappeared inside the sliding door, Fiona shifted her hips until she found a comfortable spot to sit in the corner of the hot tub. With a glance back over to Libby, she attempted to change the subject away from Callum’s embarrassment. “I’ll need to send you a friend request on Instagram, I was going to do it the other night when Callum said you were coming…but I think I just got so enthralled scrolling through your profile.”
With a movement that could only be described as sudden, Libby reached behind her and swooped up her phone into her right hand. Once she retrieved the device, a playful grin formed across her pretty face as the redhead closed the distance between the two until she was kneeling in the hot tub in front of her. “Oh, for sure, add me tonight. As long as you don’t mind me posting a different cleavage picture every few days. Other women can get awfully catty and jealous about that kind of thing. You wouldn’t believe how many girls have made little snide comments about all the attention I get on Instagram. They don’t understand that I do it to make myself feel good…and it never hurts seeing plenty of cute girls in my DMs…” With that, Libby slowly reached directly across Fiona and carefully placed her phone on the decking behind her, which allowed her chest to brush firmly against Fiona’s left arm in the process.
The comment about other women didn’t surprise Fiona as it was almost purred into her face. But the way she just brushed up against her seemed more than a little unnecessary when she could easily have left her phone where it was. But having Libby so close to her only reminded her of the way her nipples had hardened while she listened to her sexual escapades during all those stories. Whilst unsure of her footing with a girl she’d only just met, Fiona tried to think of something to say…but the only thing that was racing through her mind was the sight of Libby’s cleavage just a foot away from her face. With a hint of hesitation, Fiona finally responded. “I mean, I know that I said it earlier when you arrived…but my God, you look absolutely stunning. It’s not like I know a lot of girls who’ve had their boobs done, but I can’t believe how well they’ve turned out. I always figured that the bigger they were, the stiffer they looked, but yours just look…so…”
A soft giggle escaped past Libby’s lips as she held her position kneeling directly in front of her. With her voice lowered, Libby spoke just above a whisper as she looked directly into Fiona’s deep brown eyes. “I know! But that’s the thing, my surgery wasn’t the typical enhancement that can leave them looking quite stiff. I actually had two separate procedures done, the implants themselves and I also had a lift and reshaping done to go up to a 32DD. I didn’t actually know what my options were until I was sat in the clinic having my consultation. But once they started talking about how well they’d sit on my chest and how well rounded they’d be, I paid the deposit right then and there. It cost me £9,000, but I swear, Fiona…I couldn’t be happier with them…” As if she were performing, Libby arched her back and thrust her chest out until her barely covered breasts were positioned directly in front of Callum’s girlfriend’s face.
While not entirely comfortable with the close proximity of Libby’s extraordinary tits, Fiona knew that the conversation was too far advanced to simply escape from it. With a slight catch in her throat due to nerves, Fiona responded. “Yeah…I mean…I just can’t get over how soft they look. They bounce like they’re natural, but the shape of them is just… No wonder you’re so happy with them, Libby…just think of all the cute outfits you can wear to show them off…”
Libby’s giggling intensified as she never retreated an inch from her position, with Fiona close enough to see the outlines of her nipples through the thin black fabric of her bikini top. “Yeah, this last year’s been crazy for me. You should see the amount of money I’ve blown on clothes, honestly…my mum would go fucking bananas at me if she knew. But I’ve got so many gorgeous new dresses and I’m actually starting to think that I’m getting addicted to buying lingerie…” Libby left a very deliberate pause before allowing herself the softest gasp right into the brunette’s face before continuing. “I can’t lie though, the impact on my sex life’s been monumental. All it takes for me is to head to a club with these big tits poured into a nice tight dress…and I can have anyone begging to take me home with them. The guys are the easiest, obviously…but I swear, Fiona…you’ve got no idea just how many straight girls let me pull them into a taxi at the end of the night…”
Fiona heard the words as they were spoken right in front of her, but the innuendo that dripped from them was impossible for her to dodge. With her back squarely against the corner of the hot tub, Fiona tried to lean back to gain another inch of space in an effort to feel more at ease. Having listened to Libby’s stories for the last hour, she figured that Libby was just one of those girls who couldn’t stop herself from making flirtatious comments, even when they weren’t intended. Whether that was rationalising on her part, Fiona wasn’t sure but she started searching for ways to change the subject in as subtle a manner as she could. “Honestly, Libby…after listening to just a few of your stories since you got here…I’m in no doubt that you’re able to get exactly what you want. All I can say is that a night out with you must be quite the experience…”
Another giggle escaped from Libby’s throat, but this time it was less joyful and contained more than a hint of panting as Libby kept staring into Fiona’s eyes. “Oh, believe me…you have to come out with my friends and I one night, you’ll absolutely love it. When my surgery had fully healed and I was able to let these loose on a night out, I couldn’t stop showing them to my friends. Just us girls, obviously…in fact, let me show you what I mean…”
Slowly, both of Libby’s hands crawled up her tight midriff until they found the cups of her bikini top. With her breath starting to quicken, Libby’s fingertips gradually pulled the thin cups to the sides and freed both of her breasts right in Fiona’s face. With a slight husk in her voice, Libby continued. “I just can’t help myself, I’m so proud of them. Every time I meet my friends, all it takes is a few glasses of wine and I’m peeling off my tight bra and giving them a real close look at these big tits. Tell me, Fiona, now that you’ve got a front-row seat…how do they look…?”
There was nothing Fiona could do to stop her jaw from hanging wide open at the sheer brazenness of Libby’s display. Callum had said he’d only be gone for five minutes, and in less than half that time, Libby had summoned the boldness to display the most unbelievable set of tits that she’d ever seen in her whole life. As Fiona sucked down as much air as her lungs could hold, her eyes opened wide as she couldn’t detect a single flaw. Just as Libby had described a moment ago, it was the shape of her breasts that was lighting her on fire as she found herself trapped in the corner of the hot tub. For the size of them, they were almost perfectly rounded and made them appear so full and soft. Her nipples sat just fractionally above the centre of her breasts and Fiona knew, instantly, that they were the finishing touch from the heavens themselves. They were so tiny and sat in the middle of small oval areolas that Fiona had to fight to tear her eyes away from.
Fiona ran the tip of her tongue across her bottom lip in a desperate attempt to moisten it before struggling to find a response. She had very little experience at looking at other girls’ breasts, but there was nothing ridiculous or outlandish about Libby’s new accessories. They clearly had an augmented look, but her surgeon had perfectly captured the essence of what an upgrade like that should be about. Soft, full, rounded breasts that could stop any show dead in its tracks and reduce any man to putty in her hands. It took her a few moments, but Fiona eventually managed to tilt her head upwards to look the redhead in the eye. “I didn’t think you were going to…but…now that they’re right here… Libby, they’re just… I actually don’t know what to say, they’re just…absolutely perfect…”
Libby’s giggling had given way to a slightly laboured form of breathing that did little to mask how much her impromptu demonstration was starting to get her genuinely excited. A short silence filled the air between the two as Libby reached down under the water with both hands and pushed Fiona’s knees down until the brunette straightened her legs. With a knowing look, Libby shuffled forward and placed her left knee against Fiona’s right hip, before bringing her right knee up to do the same with its counterpart on the other side. It was then that Fiona felt Libby dropping her hips and straddling her lap, with Callum’s girlfriend trapped firmly in the corner of the hot tub. The gesture actually caused a sharp gasp to escape from Fiona’s throat as Libby leaned into her new position and left only a few inches between the brunette’s lips and her sensational bare chest.
Slowly, Libby leaned in until her lips were painfully close to Fiona’s right ear and spoke just above a whisper. “You are so kind to say that, they really are my pride and joy. Obviously, I wasn’t able to give you a proper look at them with Callum sitting out here with us… But now that he’s gone for a few minutes, and we’ve been getting on like a house on fire…I really wanted to show them to you…” Carefully, Libby reached down with both hands once more, but this time her hands softly surrounded each of Fiona’s wrists and slowly started to lift them upwards. With her lips remaining at the brunette’s ear, Libby poured a soft giggle right against her soft skin and continued. “This is always what it’s like when I’ve had a few drinks and I’m with my girlfriends. But if you think that seeing them this close is good, wait until you feel what it’s like to have them in the palms of your hands…”
Fiona felt her hands being lifted up Libby’s body, but the only resistance she could offer was to try and adjust her hips. As soon as Libby felt her wriggling underneath her, Callum’s sister simply giggled and pressed her weight back down to keep Fiona trapped in place. Eventually, Fiona’s eyes started to narrow as her hands were raised closer and closer to Libby’s chest. While she resigned herself to being unable to stop what was happening, the sensation of Libby’s curves making contact with her palms actually elicited a long, yearning moan from Fiona’s lips as she felt the heat between her own legs. Libby’s hands were holding each of Fiona’s against her tits as she stared into the brunette’s eyes and allowed herself to rock her hips against her trapped groin.
Fiona’s eyes responded by narrowing as far as they could without closing, as she felt the unmistakeable swelling of Libby’s tiny bullet nipples against each of her palms. With every ounce of resolve she had in her mind and body, Fiona actually caught herself gritting her back teeth to avoid letting her fingers close around Libby’s breasts and start groping them. As the moment descended around the two like a nebulous cloud, Fiona’s eyes started to open wide, almost affronted that they were being denied the opportunity to feast on the redhead’s breasts. With a slight tremble in both of her hands, Fiona held out as long as she could before she felt Libby’s hands start to close around hers, persuading her to take a tighter grip of the gorgeous tits whose mere presence had dominated the evening since they arrived.
With no prospect of creating space by leaning back, Fiona slowly started to sink down as Libby continued to straddle her lap so tightly. Soon, the surface of the water could be felt across Fiona’s own chest before Fiona dropped even lower, allowing the water to ripple until it could be felt brushing against the bottom of her chin. For her part, Libby simply held her hips in position as she allowed herself to lean in and maintain the distance between them as Callum’s girlfriend sunk lower and lower into the hot tub. It was only at that point that Libby’s hands freed themselves from holding Fiona’s against her chest, but the brunette’s palms were still locked in place.
It was then that Fiona attempted to gather her resolve and pull her hands away, resigned to the knowledge that she’d been coerced into groping Libby’s chest just like all of her friends in her heated stories. But when the idea crept into her head that she could end up in a story all of her own, one where her boyfriend was oblivious in the kitchen as his sister’s heaving breasts got awfully close to her lips, Fiona couldn’t stop herself and her hands acted all on their own. Slowly, with clear intent, Fiona’s eyes remained wide as her fingers sank into Libby’s sensational curves until she felt her hard nipples scraping against her palms. Her breasts were so soft on the surface, but it didn’t take long for Fiona to feel just how firm they were as her fingers sank so pleasingly into her chest.
Immediately, Fiona knew that she’d made a mistake and began to search for a way to play it off just as Libby had done. That they were exactly as the redhead had described, two girlfriends who were messing around before Callum got back. With a slight catch in her throat, the water continued to stroke Fiona’s chin as she looked up into Libby’s eyes. “Honestly, Libby…I didn’t mean to… When you asked me to touch them…are you sure this is…ok? This is what your friends do with you?” As her words filled the tiny gap between the two, Fiona tried to stare into Libby’s hazel eyes to get a read on her, but Callum’s sister wore a focused look as her breath had started to become ragged. Carefully, Fiona kept searching for the words as her hands remained glued to Libby’s breasts. “You were right though…as good as they look, I can’t believe how amazing they feel…” With a playful laugh of her own to attempt to relieve some of the tension, Fiona continued. “How do you get your friends to stop? That’s what I want to know…”
Slowly, Libby’s left arm brought itself to the surface of the water and draped itself around Fiona’s neck, as her right arm did the same around the other side. With a wicked grin on her face, Libby’s plump lips leaned back in until they collided with the brunette’s right ear and she whispered. “That’s the thing, Fiona…who said anything about them stopping? My good friends…my best friends…they can never last more than a minute of this before they lose control and I feel their lips and their tongue against these tits…” Just then, Libby’s bottom lip made contact with Fiona’s earlobe and firmly brushed against it before the redhead allowed her warm breath to pour against her smooth skin. “As for the strangers? Well, let me tell you something that I find interesting about our nights out. It turns out, all I need to do is take one of those pretty straight girls into a dark corner in the club. Somewhere where I can get up close to them, just like we are now…and I put these tits right in their beautiful face. Here’s a question for you, and I want you to take a moment to think about it properly… How many of those girls do you think were able to resist me when my head would lean in and my tongue would slip straight into their mouths…?”
The intensity of Libby’s question was enough to provide the spark of resistance that Fiona had been searching for, as she softly shook the cobwebs and lifted both of her hands from the redhead’s chest. All night, ever since Libby arrived, Fiona knew that she was a minx. But as much as she had no idea if Callum’s sister was just fucking with her, every fibre of her being knew the answer to Libby’s question. Soon, all Fiona could picture in her own mind was a long line of beautiful girls, all of whom were powerless to stop Libby’s lips from crashing against their own. When Fiona recalled the point Libby had made earlier in the evening about pulling straight girls into a taxi back to her place, the groan that escaped from the back of her throat was long and searching.
With Libby’s hazel eyes locked onto her own, the weight of the silence was starting to feel heavier than the sensation of Libby’s crotch pressing into her lap. After sucking down a deep breath, Fiona got lost in the redhead’s gaze as she responded. “Libby…I get that you and your friends like to play around, I think that’s so cool… But we’ve only just met and I’m not like that… Callum’s going to be back any minute, but even if he wasn’t…” Slowly, both of Fiona’s hands dropped down and disappeared beneath the surface of the water, but they had nowhere obvious to settle except to take a keen hold of Libby’s hips. “I don’t doubt for a second those girls you meet…those girls you seduce…are looking to experiment, but I need to be clear with you, Libby… I’m straight…”
It had only been a few minutes, but Libby’s seductive giggle returned with a vengeance as she leaned back in and her lips returned to Fiona’s ear. “Now, Fiona…you don’t need to feel uncomfortable around me…especially after taking such good care of Callum these last few months! He likes so you much, I can tell by the way he looks at you. That tight little body and that gorgeous smile, trust me…you’d fit in just fine on a night out with us. If it was up to me, you’d be the one that I’d be dragging into that dark little corner of the club…all so I could find the perfect opportunity to do this…” Without a moment’s pause, Libby arched her back and leaned in closer until the erect nipple on her right breast, straining with desire, made contact with Fiona’s bottom lip. Callum’s girlfriend remained frozen throughout as Libby let out a sultry moan and dragged the hard nipple straight upwards, which allowed it to scrape delightfully across both of Fiona’s lips.
Rather than fight the gesture, all Fiona could offer in response was capitulation as her hands tightened around Libby’s hips beneath the surface of the water. The swollen bud had only retreated from her lips by a couple of inches as the redhead maintained her position, but the heat between Fiona’s legs was demanding that she lean back into Libby’s chest and lose all control. Soon, Fiona pictured herself being dragged into the corner of a dark nightclub, with her back trapped against the wall, as Libby’s lips slowly made their way closer to hers. The very thought prompted the slender brunette to actually shake her head in an attempt to come to her senses, something which she desperately needed before Callum caught the two in the impromptu embrace.
After sucking down a few deep breaths, Fiona slowly looked upwards until she found Libby’s gaze. With her throat slightly rasping, she responded. “Look, I get it, I really do…you like to fool around, I appreciate that. But, Libby…you need to understand something… I’m with your brother, and he’s about to walk through those doors any second now. If he does, and you’re sitting in my lap like this…with those tits in my face…” Despite offering strong protestations, the heat between Fiona’s legs started to peak as she recognised that Libby had no interest in retreating out of her lap. As she felt her fingers curl around Libby’s hips once more, Fiona gasped as she continued. “Come on, Libby…I know you’re just messing around…but if he comes out here and sees us like this, Callum’s going to have a heart attack…”
Slowly, Libby straightened her back and started to lean back down, but this time kept her face directly in front of Fiona’s. As she felt the brunette’s hands almost glued to her hips, Libby kept her arms softly draped around both sides of Fiona’s neck and purred. “Don’t worry about Callum, he won’t be back for a bit…and it’s just us girls out here…getting to know each other…” A small gasp escaped from the back of Libby’s throat as she looked directly into her deep brown eyes. “You want to know what I think? Let me tell you something, Fiona…one of my favourite ways to get to know a girl as beautiful as you…is for you to reach up and play with these big tits that you’ve been admiring all night, while you let my tongue slip into your mouth…” Libby barely managed to get her words out before moaning right into Fiona’s face before she steeled herself to finish her thought. “Have you any idea how gorgeous you look right now? I’ve sat there across from you, watching the way that bikini just clings to your body…you’re driving me fucking crazy. I can promise you one thing, when we kiss…it won’t matter if Callum storms out here and catches us red-handed…no one’s going to be able to make me stop…”
With that, Libby let out a soft gasp as she started to slowly lean in, allowing her plump lips to start to close the distance towards the brunette’s. For her part, Fiona had absolutely no room to manoeuvre and could only respond by freeing her hands from the redhead’s hips. Libby’s words were starting to swirl in her mind as she pictured the scene that was just described, with Libby refusing to break the long, slow kiss despite Callum catching them in the act. Just the thought of surrendering in that manner had Fiona’s pussy dripping wet as she couldn’t stop her hands from rising back above the surface of the water and crawling up Libby’s tight body. With only an inch between their lips, Libby paused and held her position, teasingly, maddeningly, as she felt Fiona’s hands reach up until they clamped around both of her breasts once more.
Libby’s eyes started to close as she felt Fiona’s tentative groping start to develop into a more intense act, one which laid bare the brunette’s tortured desire. When Fiona’s fingertips dragged themselves firmly against Libby’s hard nipples, the redhead moaned like a wanton slut, right in Fiona’s face, as she purred. “I think it’s time you showed me just how much you want to kiss me…”
Not even the prospect of Callum returning back out onto the decking could rein Fiona in as her fingers closed around Libby’s seductive curves once more. With Libby’s arms draped either side of her neck, she didn’t have much room to turn her head as Libby’s lips drove forward and planted themselves against hers. The moment they made contact, Fiona could feel Libby start to grind in her lap as the redhead wickedly allowed her lips to smack free before the tip of her tongue slithered out into the open air. Fiona was awestruck as she felt Libby’s tongue slip past her lips and slide gently against her own, while every grope and caress of the redhead’s tits was coaxing the most delicious moans from the skilled seductress.
For the first few moments, Fiona could feel the chaos in her own mind as so much of her was pleading with herself to come to her senses. She knew the direct nature of Libby’s seduction didn’t make it any more acceptable. It didn’t matter that she was so assertive. It didn’t matter that Libby wasn’t taking no for an answer. Fiona knew that the moment she started kissing her back, she was cheating on Callum.
But the realisation never managed to take a strong enough hold in Fiona’s mind. As loud as her internal objections were, they were drowned out by the sensation of the glorious breasts that she was busy kneading and groping while Libby’s tongue was lighting her on fire. Never in her life had Fiona ever come close to kissing another girl, but the way that Libby controlled every element of their embrace was just fanning the flames of Fiona’s arousal.
Fiona’s eyes were closed as she felt Libby’s tongue withdraw, only for her plump lips to press themselves against her bottom lip, surrounding it. Slowly, Fiona felt her lip being gently sucked upon and pulled fractionally outward, before Libby’s tongue returned to slip effortlessly back into her mouth. The kiss never broke for a second as Libby reached up to her chest and surrounded the brunette’s left wrist, before pulling her hand away and dragging it back beneath the surface of the water. Only this time, Fiona’s hand never found its way back to Libby’s hip as it was directed squarely onto her tight ass.
No part of Fiona felt like it was in control as she allowed herself to be teased by Libby’s lips as her hands were groping so tightly against the fullness of her tits and her firm cheek. She tried to tell herself that she simply couldn’t believe how quickly Libby had managed to penetrate her defences, but she knew that wasn’t true. Ever since she arrived, Fiona knew what she was dealing with. A seductress with a scorching hot body and such a beautiful face, with long red hair and an attitude that she would take whatever she wanted. Even if that meant seducing her brother’s girlfriend at the first opportunity.
Just then, as the pace of the kiss had started to quicken, Callum’s voice called out from deep inside the kitchen, seemingly oblivious to the tryst that had developed in the hot tub. “Do you want me to bring any of this chicken out for you both? I can wrap it up and put it on a plate if you want…”
The sound of her boyfriend’s voice caused Fiona to freeze as she slowly opened her eyes and was relieved to see that he hadn’t yet returned out onto the decking. Responding to Fiona’s hesitation, Libby’s lips softly broke free from hers as a thin strand of saliva was stretched to breaking point, before Libby’s head retreated backwards and severed the connection. As Fiona gulped down as much air as she could handle, a wicked smirk crawled onto Libby’s pretty face as she felt Fiona’s hands release themselves and drop back down to her sides.
Carefully, Libby afforded herself a look back over her shoulder and called out in response. “Yeah, you better bring it out here as quickly as you can. I’m absolutely starving, all I’ve had in the last few hours is this wine.” Slowly, Libby looked back into Fiona’s eyes as she reached up towards her own chest and pulled the thin black cups of her bikini top back into place.
With her cleavage restored and the healthy portion of her breasts showing from under the small garment, Libby giggled softly and spoke up. “It must be almost 18 months ago by now… I was staying here at the house during my Christmas holiday. Callum was seeing this girl, honestly, Fiona…she was absolutely stunning. She was like a little blonde airhead, but I couldn’t stop staring at her tits every time she came round to see him…” Libby allowed the comment to hang in the air as she remained straddling Fiona’s lap with intent. “One of the first nights she stayed over, it was pitch black in the hallway and it must’ve been about 2:00 a.m. I was lying in bed watching a movie on my laptop when my bedroom door opened and she stumbled inside… Of course, when she realised her mistake, she apologised and went to go back into Callum’s room…”
As Fiona listened to the story, the memories of what she just experienced started searing themselves into her mind. The heat of the kiss and the way Libby’s body felt as her hands roamed all over it, all while she hopelessly surrendered as her pussy got so wet. It felt like she’d just went through an event so transformative that she was a whole new person as she remained there, trapped under Libby’s weight. But the aura that the redhead wielded ensured that she paid the utmost attention as Libby’s story continued, with Fiona’s eyes ensnared by Libby’s gaze.
The short silence felt like an eternity before Libby giggled and continued. “Now, what kind of host would I have been if I’d have just let that little bimbo tiptoe back into my brother’s room? Let me assure you, Fiona…that was never going to happen. Once I pulled her back inside and sat her on the bed, she told me that Callum had fallen asleep. Well, I wasn’t going to let that opportunity slip away, was I? From there, it really didn’t take long for me to rip two pillowcases free and wrap them around her wrists, tying her to my bed…and I spent the next hour riding her pretty face until she started begging me to lick her wet little pussy…”
Despite her best efforts to maintain her composure, the memory elicited a long groan from Libby as her eyes briefly fluttered. After a moment, Libby calmed herself and returned to Fiona’s gaze. “I can’t wait for you to get lost and stumble into my room… I’ve still got the same two pillowcases that I used on that gorgeous little blonde. Mind you, the way you just kissed me…the way your hands felt against these tits…I don’t think you’ll need to be lost to find your way into my bedroom… Just know that once I get you inside, don’t think I’m going to let you out until you feel my tongue dancing across that little pussy of yours…and I’m going to take my time…”
Just as Libby started to finally retreat from her position, crawling out of Fiona’s lap and reaching across her shoulder to retrieve her phone, Callum walked towards the sliding doors and stepped out onto the decking. In his right hand was a large plate with lightly-salted chicken breasts that had been clumsily wrapped up just moments earlier. Fiona glanced across at him as she felt the relief of Libby’s weight leaving her lap, but the guilt of what had just transpired was written all over her face through the intense redness of her cheeks.
As Callum approached the edge of the hot tub, Fiona calculated that he was too close for her to offer a genuine response to Libby’s scorching tease. She knew, of course, that Libby was being straight with her. She had no doubt in her mind that she thought nothing of fucking Callum’s ex-girlfriend while he slept, oblivious, in the next room. Meanwhile, there was no doubt in Fiona’s mind, whatsoever, that Libby wanted her in the exact same way. Bound, struggling, panting with need…as Libby’s glistening pussy dropped itself squarely onto her face. Even as the thought had barely formed in her mind, Fiona cursed herself as she felt the heat between her own legs which simply didn’t care if she ended up cheating on Callum as Libby’s helpless plaything.
As soon as the realisation settled within her own mind, Fiona stood up in the hot tub and started walking towards the steps. Without hesitation, Fiona climbed out of the water and stood up on the decking as she looked into Callum’s eyes. With the knowledge of her own infidelity eating away at her, Callum’s girlfriend knew that she wanted to be anywhere but around Libby at that time. With a slight grimace, Fiona spoke up. “Babe, I know I drove over here tonight, but there must’ve been something in that wine that isn’t agreeing with me. I’m going to call a taxi and spend the night at home in bed, I’ll call you in the morning and we can make plans for the day?”
Slowly, Callum sat the plate of chicken down near the edge of the hot tub as he stood up straight and looked into Fiona’s eyes. “Are you sure? Whatever it is that you’re feeling, it must’ve hit you pretty fast… I can come with you, we can just chill and get an early night if you aren’t feeling too good…”
At that moment, Fiona’s legs started moving almost on their own as she raced towards the back door. “No, no…stay here with Libby, she’s just arrived… You two have got a lot to catch up on, I’ll be fine. Just stay out here, I’m literally going to order a taxi right now and just grab my stuff and go. Once I’ve had some rest and I’m feeling better, the three of us can spend some more time together…”
However, as Fiona practically bolted inside, Libby’s gorgeous face wore the most sinister smile as Callum’s back was facing her. Libby appreciated the sight of Fiona’s tight cheeks as she went into her obvious retreat, but she savoured the victory of having driven her brother’s girlfriend away for the rest of the evening. As Fiona disappeared from view and Callum started to turn back around to face her, Libby was overjoyed by the prospect of Fiona feeling too awkward to return on account of her being there. It was then that Libby teased herself with the fact that she’d be spending the next 13 days at home with her gorgeous brother, all alone with no one to get between them.
A few hours later, it was just after midnight when Callum walked into his bedroom and made sure to close the door tightly shut behind him. After Fiona’s abrupt departure, Callum had spent the rest of the evening in the hot tub with Libby as he struggled to find the strength to stop ogling her sensational curves without getting caught. But as he pulled his wet shorts off and tossed them into his laundry basket, all it took was the faintest recollection of the way Libby’s tits sat so proudly on her chest and Callum could do nothing to stop himself from swelling to full hardness.
With just the lamp switched on atop his bedside cabinet, Callum didn’t even dry the remaining moisture from his legs and feet before he sat down on the edge of his bed. After taking a moment to try and gather his thoughts, Callum swore that he was starting to lose his mind by the way that his sister’s stunning body was captivating his thoughts. At that point, he reached out and grabbed his phone as he desperately tried to disassociate his current state of arousal from Libby’s mesmerising assets.
Frantically, Callum climbed up onto his bed and lay on top of his duvet, completely naked, as his rock-hard dick was throbbing and desperate for release. Initially, Callum opened his Instagram feed where he followed a who’s who of the world’s hottest models, where he was certain that he could convince himself that his straining erection could be attributed towards someone else…anyone else… But as he scrolled down through his feed, with stunning fitness models and influencers poured into the most scandalous lingerie and swimsuits, it felt to Callum like nothing was grabbing his attention, not even his absolute favourites.
Due to the lateness of the hour, Callum dropped his phone down onto the bed for a moment as his eyes briefly closed. But once they did, they failed to open back up as something in the darkest parts of his mind took a firm hold of him as he saw himself standing inside a strange room.
Quizzically, Callum tried to understand what his mind was showing him, but he didn’t recognise much of his surroundings. He was sitting on the black leather couch from his living room in just a tight pair of black boxers, but he was enclosed within a glass box that was no larger than his bedroom. Meanwhile, the thick glass walls and ceiling were positioned in the middle of what appeared to be some kind of control room, with various engineers in lab coats manning their stations all around the perimeter of the area. As Callum looked around, it seemed like he was in a fairly calm environment, but he noticed that some of the instruments and workstations had small plumes of smoke and flashing amber lights that were commanding the engineers’ attention.
As the scene that his mind was painting for him continued to play out, Callum went to stand to his feet before he realised that he wasn’t alone. When he looked up, the figure of Libby suddenly appeared right in front of him as her body was still gleaming from their evening in the hot tub. Her smouldering enhanced tits were threatening to break loose from the tight black fabric of her bikini top, while the way her bottoms clung so tightly to the smooth skin above her hips had Callum almost panting with desire. While Libby’s awesome figure crept closer, Callum froze in position on the couch as her sudden appearance in the strange room resulted in more amber lights flashing all around the perimeter surrounding them.
Once Libby was standing directly in front of her brother in the glass box, with him sat on the couch, she took a moment to look all around the room at the different engineers, lights and consoles. It was then that she returned to her brother’s gaze and spoke first. “They seem to be in some kind of distress… I wonder what it could be that’s gotten them so worked up? Perhaps it’s because you saw something out in the hot tub that’s left you a little hot under the collar?” Slowly, Libby’s right hand crawled up her body until she allowed herself a long, firm grope of her own breast as she moaned right in front of Callum’s face. “If you’re telling yourself that I wouldn’t have noticed all those glances at these big tits…just how hard that big dick got for me under the water… If you’re going to insist on telling yourself those lies, then you’re going to need a new strategy to deal with the chaos that’s about to unfold right here in this room…”
While the fantasy was deeply unsettling to him, Callum knew that he could engage with the image of his sister as he was really alone in his bedroom. But the entire scene felt so real to him, like his subconscious had been stirred in such a way that the lurid picture which it was painting was almost inescapable. As his lips parted, he looked into Libby’s dark brown eyes and responded. “I don’t know why we’re here together…why we’re here in the middle of this room…but there isn’t going to be any chaos. I don’t know what it was, I just haven’t seen you in so long… Fiona and I had been drinking, whatever reaction I had to you was just a complete one-off…”
The smile on Libby’s face conveyed just how little she cared for his objections as she began to twirl around slowly. While she did, Callum’s sister ensured that he got a perfect view of her toned thighs and tight cheeks, with her bronzed skin looking absolutely glorious with just the tiny scrap of black fabric covering her perfect breasts. When she stood back in front of him and looked him in the eye once more, Libby giggled as she responded. “Now that you’re all on your own and your girlfriend’s not there to stop you, why don’t you do what you’ve been dying to from the moment you saw me in this tight fucking bikini? It’s time for you to take a nice deep breath and imagine what it would be like for me to crawl into your lap, with these big tits so close to your face…before I lean in and slip my tongue into your mouth…”
When the sinful words spilled out into the air, more plumes of smoke started to spray out from different pieces of equipment around the perimeter of the room. After a couple of amber lights turned red and more of the engineers started to run across to address the problems, Callum felt Libby creeping closer as she glanced down and saw just how hard his bulge was beneath his boxers. When her movement didn’t stop, Callum gritted his teeth as he visualised Libby crawling into his lap until he felt her hips dropping.
Immediately, Callum’s eyes opened as he lay atop his bed and he leapt up onto his feet. A few beads of sweat had formed on his brow as he tried to comprehend just what his mind had shown him. So much of him knew that Libby looked amazing out in the hot tub, but he was dismayed to find that her imprint had been left on him to the degree where he just fantasised about her while his dick was as hard as it had been in a long time. But it wasn’t just her physical appearance that had enthralled him, as the way her wicked aura descended upon him whenever she talked about her busy sex life was threatening to rewire his brain. As he stood there, alone in his bedroom, Callum realised that whatever spell his sister was capable of casting on him, it was going to be a long two weeks alone with her if he couldn’t pull himself together.
With haste, Callum pulled on his boxers, t-shirt and tracksuit bottoms that he’d changed out of to go into the pool and stepped into a pair of running shoes. He almost had to force himself to think about his girlfriend as he left his bedroom with the intention of going for a late-night run to clear his head. But as he walked out of the front door of the house and closed it behind him, any thoughts he had of Fiona’s wellbeing were firmly replaced by the thought of Libby peeling her scandalous bikini top off while she was alone in her bedroom.
Two days later, Callum was sitting on the black leather couch in the living room as he was spending the early part of his Saturday afternoon watching motor racing highlights on television. The great weather in Glasgow had continued as the resultant heat had led to Callum sitting in just a pair of black running shorts and a simple matching t-shirt.
It was just after 1:00 p.m. when Callum tried to gather his thoughts as he watched the expensive cars race around the track in a qualifying session. Since Fiona’s abrupt departure two nights earlier, she’d been in touch to let him know that whatever bug she’d come down with had left her bedridden. While his girlfriend’s story was technically true in that she’d spent so much time in bed, he wasn’t to know that the bug she’d come down with was his gorgeous sister. In truth, Fiona had spent so much time in bed setting aside her guilt and playing with her pussy, she’d barely managed to squeeze in the time to call Callum and assure him she was doing fine on her own.
As he lay back against the comfortable leather couch, Callum was immediately distracted by the sound of the living room door slowly opening. When he turned to anticipate his sister’s imminent arrival, all it took was one look at her and his guilt came flooding back from when he fantasised about her after their night in the pool.
Callum simply couldn’t peel his eyes away from her as Libby almost bounced into the living room, with a big smile plastered all over her pretty face. Her long red hair was tied up into a messy bun, with strands of hair flowing down from her fringe either side of her face to meet her chin. But every little step she took resulted in her breasts jiggling and softly bouncing as her thin pink cardigan was offering her enhanced chest very little support. The cardigan was long-sleeved, but the hem was slightly cropped to ride above the waistband of her matching pink pyjama shorts. Meanwhile, the only three buttons on the cardigan were clustered directly under her breasts, which allowed the neckline to swoop so low that the cleavage Libby was displaying left Callum needing to take a deep breath.
When she reached the couch, Libby playfully jumped down onto the seat to his left and spoke up. “I only got up an hour or so ago, I was up half the night texting someone new that I’ve met… Honestly, Callum, I’m going to need you to come into my room and take this phone out of my hand if I do that again. It was daylight outside when I finally went to sleep….” Once she was content that his eyes hadn’t managed to free themselves from her body, Libby giggled as she held her phone in her right hand. But as her bare legs pressed themselves against his, Libby leaned in closer towards him and continued. “Have you got any plans with Fiona today? Is she feeling any better now that she’s got some sleep?”
In his current state of mind, the last thing Callum wanted was to feel his sister’s smooth skin brushing up against his bare legs. However, the thought was only allowed to form in his mind for a moment before he realised that he needed to focus all of his attention on not glancing down at her cleavage as it sat right in front of his face. After sucking down a further deep breath, Callum compelled himself to hold his sister’s gaze as he responded. “I still don’t know what’s going on with Fiona, she called me this morning and said that she’s feeling a bit better…but that she’s going to spend the weekend in bed. I told her that she could stay in my room for the next few days, but she said she doesn’t want either of us to catch whatever she’s got… We never spoke on the phone for very long, but…I don’t know… It just seems like she’s got a lot on her mind and it’s happened out of the blue…”
For a moment, Libby allowed herself to flash her brother a sympathetic look before her natural instinct took over. As the grin crept back onto her face, Libby purred. “That’s such a shame, I was hoping that the three of us could spend so much time together before Mum and Dad get back… Isn’t she gorgeous though? Fiona’s got such a tight little body… It’s probably for the best that she can’t come over, or else you two would be spending all day in bed and I’d be left feeling like a spare part…” As the grin widened across her pretty face, Libby continued. “Not to worry though, that just leaves you and me on our own. We’ve spent so little time together this last year…we’re going to have to get to know each other all over again… If you think about it Callum, it’s almost as if we’ve become strangers instead of siblings…”
Briefly, Callum contemplated Fiona’s thoughts from before Libby arrived. While he knew that both his girlfriend and sister were right, that he hadn’t made the right effort to maintain his relationship with Libby, the events since Libby’s arrival had just reinforced his level of discomfort. Even as he sat there next to her on the couch, Callum was almost dumbstruck by how difficult his sister’s new assets were to conceal. The way the thin pink material clung so tightly around her upper body had him wondering if she truly cared whether her cleavage was inappropriate considering it was just the two of them at home together. As she gently twisted and turned, Callum could clearly see a healthy glimpse of the black lace of her bra as it crept into view, which offered Libby’s breasts an extra degree of lift that she hardly needed.
Once he realised that his gaze had somehow slipped back down to appraise her cleavage, Callum silently rebuked himself as his head snapped back upwards until he was looking into her deep hazel eyes. “You don’t need to worry about that, I’m still the same guy I’ve always been… But you’re right, there’s going to be plenty of things we can do together over the next week or so. I don’t know what Fiona’s plans are going to be…”
Suddenly, Libby shot her right hand out until it landed on Callum’s left wrist as she interrupted and spoke over the top of him. “I’m so glad you said that, because I love going out on a Sunday night… It’s one of my favourite things about Glasgow, there are so many great places to go and I never get to do it anymore as I’m stuck up in Aberdeen. Tomorrow night, you and me need to go for a few drinks and we can have a proper catch-up session… I’m warning you now though, no horrible little student bars…we’re going somewhere with a bit of class so I can dressed up… It’s actually perfect timing because it sounds like Fiona’s going to need a few more days to get over the other night…”
Between the sensation of Libby’s hand clutching his wrist and her bare leg pressing against his, Callum swallowed hard as the same aura that his sister wielded in the pool started to make itself known once more. As he listened to every word that spilled past her plump lips, Callum felt the air of confidence that was exuding from his sister as he responded. “Yeah, tomorrow night’s fine… As long as we’re not out all night though… After listening to all your stories from the other night, I’m not sure I can hang in there if you’re looking for a wild night out…”
Quickly, Libby lifted her phone and swiped with her thumb to unlock the device. After her thumb pressed down decisively on the screen a few times, she offered a wicked giggle as she found what she was searching for. Once she did so, she handed the phone to her brother before she replied. “I was saying to Fiona the other night, I’ve been buying so much new clothes that I’m starting to become a little obsessed… But ever since my surgery, there’s nothing I love more than putting together the cutest looks to show off my new accessories… Why don’t you have a look at the first few pictures on that phone and tell me what you think? Whichever one you think looks best, that’s what I’ll wear tomorrow night…”
Callum didn’t so much pick the phone up as it was thrust into his hand by the mischievous redhead. But once the device was unlocked and it was in his hand, Callum looked down and braced himself for the impact of what he was about to see. All throughout the last year, he’d stayed away from Libby’s Instagram page like it carried the plague as he’d heard all about how great she looked from his friends. But once his eyes focused on the screen, the sight of what awaited him sent a rush of blood to between his legs.
In the first picture, Libby was standing in front of her full-length mirror in what appeared, at first glance, to be a simple grey t-shirt and matching yoga pants. However, it took Callum all of half a second to recognise that the shirt clung so tightly around his sister’s chest that she obviously wasn’t wearing a bra. The shirt sported a high crew neck that completely covered her salacious cleavage, but the hem was cropped to immediately underneath her chest which afforded a healthy view of her flat tummy. Meanwhile, the way that both of her nipples were rock-hard and straining underneath the thin grey fabric almost coaxed a soft moan past Callum’s lips as he marvelled at the size and shape of Libby’s incredible tits under her tight shirt. When his mind dragged his focus away to pinpoint exactly where her nipples sat on her breasts, Callum fought with everything he had to control himself as his sister was sitting right next to him on the couch.
Before he could answer, Libby’s voice lowered slightly as she started giggling right into his left ear before she continued. “I love this look so much. I know, it’s a little casual…and the neckline is really high…but when the shirt’s as tight as that, it just looks hot as fuck, don’t you think? I tried wearing a bra with it, but it kind of spoils the look I’m going for… What do you think though? A little too casual for drinks? Maybe this would be better for going out shopping instead…”
Just hearing her toss in the detail about going braless just added so much heat to the thoughts that were flooding through his mind. At that stage, Callum knew exactly what his sister was driving at. She wanted to flaunt her new assets at every turn, and if that meant her hard nipples were practically on display then that’s exactly what Libby was going to do. Carefully, and as diplomatically as possible, Callum searched for the right words to respond with as he looked back up into her hazel eyes. “You’re right, it’s casual… Libby, there’s no easy way for me to say this…but after your procedure…I don’t think you ever have to worry about whether you look good in any of your outfits ever again… Yeah that’s shirt’s really tight, but it really suits you… I think you look amazing…”
The look on Libby’s face was a sight to see as her eyes lit up and the smile on her face was beaming. “Aww! That’s so sweet, Callum! How relieved are you to finally have a conversation about my new tits? You know, if I find out that the reason my little brother’s been avoiding me for a whole year is because I got my boobs done…I’m going to be so cross with you…”
Without moving from his position, Callum did feel some initial relief at having brought up her cosmetic procedure for the first time. Just as he felt better when he finally saw Libby in the flesh for the first time in a year when she showed up two nights earlier. But as he desperately asked himself if his compliment was too much for the occasion, he honestly felt like he’d managed to find the right balance between being honest and truthful. “Look, Libby… What you need to understand is that all of my friends know about you… Every time we go out, it never takes long for one of them to bring you up in the conversation and you’re all they want to talk about… I don’t know, I don’t have a problem with the fact that you look great… I think I just needed to get away from any situation where people keep asking me about you or telling me about whatever new pictures of yourself in a bikini that you’ve posted to Instagram…”
Slowly, Libby’s right hand crept up until she gently placed her index finger against his lips. Once her gesture had successfully managed to silence his ramblings, Libby looked into his blue eyes and spoke. “I knew that’s what was going on… You know, if you ever went on my Instagram page, you’d see that I’ve never responded to any of your friends’ comments or reacted to them in any way. I’ve got more than enough people following me to spend time flirting with your friends. We used to be so close, you’ve got no idea how frustrating it is to hear that you’ve been avoiding me…”
As her finger dropped from his lips, she kept looking into his eyes as she continued. “You know what, Callum? I’m going to tell you something right now that I want you to remember any time you start to feel awkward around me. Ever since I got these new tits, there isn’t a man on the face of this planet that doesn’t want to fuck me… Not one… All those guys on social media, all their likes, all their comments… I can promise you one thing, there’s no one nicer to a girl with a body like mine than a man who hasn’t fucked me yet… They all say the nicest things, but just because I show off my cleavage in most of my pictures, it doesn’t mean that any of them have got a chance with me. So, if you’re worried about what your friends are going to say about me…or what Fiona thinks…please, don’t let that come between us anymore…”
Callum found himself nodding softly in acknowledgement as he pondered his sister’s advice. But it didn’t take long for the confident nature of her boast about being able to have any man she wanted to settle at the forefront of his mind. Once his mind teased him with the recollection of how he got so hard for her when alone in bed on Thursday night, it didn’t take a massive jump for Callum to consider what it would be like for her to have him in whichever way she pleased. As perverse and taboo as the thought was to him, Callum felt himself starting to fall deeper under Libby’s mesmeric enchantment. While he sat there, attempting to have a conversation with his own sister, all it took was for her to throw in a sultry boast or gratuitous reference to her big tits and Callum would find himself desperately trying to defend himself against the thoughts that would race through his head.
Slowly, Callum gathered himself as his lips parted. “I know, Libby… Honestly, I know what you’re saying… It’s not all bad though… Now that you’re here, it’s starting to feel like old times again. Before Fiona left, she said she thought you were amazing. Having said that, I promise that I’ll make more of an effort to keep in touch with you… All I’m asking is that if any of my friends try and get you to talk to them, please…just ignore them… If even one of them gets your attention for a few minutes, I’m going to be hearing about it for months…”
With a smouldering look on her face, Libby glanced down and dragged her index finger across the screen to swipe to the next picture. As Callum’s gaze dropped to take in the sight of what awaited him, his instant reaction was to allow his lips to part as a soft groan escaped out into the open air.
Libby was stood in the same pose in front of her full-length mirror, but the casual grey t-shirt had been swapped in favour of a stunning gold shirt. The garment was long-sleeved and had a metallic finish which gave the shirt an additional shine, but Libby had only fastened two of the buttons underneath her breasts. As a result, the tight shirt hung open underneath to offer a glimpse of her toned stomach, but her black lace bra was clearly visible as it helped form a seductive cleavage that was well capable of stopping traffic. Meanwhile, both of the sleeves were rolled up past Libby’s elbows and her look was complimented by an equally tight black miniskirt that barely managed to cover her black lace stocking tops. Once Callum managed to peel his eyes away from Libby’s bra and glanced down at her thighs, the sight of the stocking tops almost stopped his heart as he fought the urge to visualise her standing there in her lingerie set.
Unlike the reveal of the first picture, Libby remained silent as she allowed the silence to build. With her lips still positioned at his left ear, Callum felt her warm breath pouring against his skin as he realised that he had to offer some kind of coherent response to his sister’s stunning outfit. “I mean…wow…that’s got to be it… You look incredible in that picture… Are you sure that it isn’t a bit much for a Sunday night? Seriously though, you look absolutely amazing…”
Libby’s giggling continued as she allowed her lips to gently brush against her brother’s ear. “I’m glad you like it because that’s exactly what I’m going to wear tomorrow night. That person I was texting last night, I’ve been texting her on and off for the last month. Once I knew I was coming back down to Glasgow, we agreed to meet for a quick drink tomorrow night. She’s going out with her friends tomorrow, but she’s insisted on dropping in to meet me… It’s very hard to say no to her, but you’ll get the idea once you meet her. Every time she speaks to me, she never takes no for an answer… Trust me though, Callum…she’s fucking gorgeous… Once I sent her that picture you’re staring at, she said she can’t wait to meet me…”
The revelation that his sister had been up half the night flirting with another woman only poured petrol on the flames of Callum’s arousal. He’d heard some of Libby’s stories about other girls in the hot tub, but the suggestion that she was being pursued by another stunning girl was making it hard for him to suck down enough air and control the reaction between his legs. In that moment, he gritted his teeth as he managed to turn away from the phone and look back into his sister’s hazel eyes.
For her part, Libby was enjoying the way her gorgeous brother was reacting as she sensed he was turning into putty in her hands. Once she realised that he couldn’t find the words to respond, Libby softly giggled before she continued. “I met her on a dating website, I sent her a quick message once I saw her picture…but ever since then, she’s been pretty relentless. Do me a favour though, don’t swipe away from that picture whatever you do… The next one in the gallery is what I sent to her last night…only the shirt and the bra were lying on my bedroom floor… It’s hard to describe the way she talks to me, she’s just so fucking dominant… Once she told me that she wanted me to send her a picture of these big tits, I’d started peeling off my clothes before I even realised what I was doing…”
Despite having been in Libby’s presence for a few days where he’d heard all about her recent sexual exploits, the complete lack of boundaries she was exhibiting with him was absolutely intoxicating to Callum. As he glanced back down at the phone in his hand, his brain told him that all he’d have to do was swipe the screen and he’d be presented with the majestic sight of his sister’s expensive upgrade. While his black shorts weren’t particularly tight, there was nothing Callum could do to suppress the swelling between his legs as he felt his hardness start to build. As horrified as he was that his body had reacted to Libby in that way, Callum panicked and tossed the phone down onto his sister’s lap as he quickly stood to his feet. However, once he got there, he couldn’t stand facing her in case his state of arousal became obvious to her.
At that stage, Callum resigned himself that he simply had to get out of the room and compose himself. After taking another deep breath, Callum started walking towards the living room door as he called out to Libby. “Whoever she is, she’s going to take one look at you in that outfit and she’ll love what she sees… I haven’t showered yet today, so I’m going to take one now and try to cool down. It’s so clammy with this heat…”
Just like Fiona did when she left so abruptly two nights earlier, it was Callum’s turn to go into full retreat as he stepped out of the room and left his sister sitting on the couch. As the same wicked smile made its way back onto Libby’s face, she glanced down at her chest and was satisfied that enough of her cleavage had been exposed by her tiny pink cardigan. Once she relaxed and lay back against the leather couch, she afforded herself a few moments to revel in how easy it was to get her brother so worked up. When her head found a comfortable spot against the arm of the couch, Libby tried to imagine the way in which Callum’s dick would swell to full hardness, all because of the way she was flaunting her body at him. At that moment, it didn’t take long for the thought of his hard cock to leave her pussy dripping wet.
Just over half an hour later, Callum opened his bedroom door and stepped inside before he swung the door closed shut behind him. With just a damp towel wrapped around his waist after his second shower of the day, Callum reached down and turned the lock just above the door handle to ensure that he wouldn’t be interrupted.
Every little movement carried a sense of urgency that conveyed just how much he had on his mind. After he pulled the towel from around his waist, he tossed it straight into his laundry basket as he leapt up onto his bed. But as he did, he exposed just how hard his cock was as it was throbbing and desperate for his attention. With a firm tug, Callum yanked his duvet cover off the top of the bed and tossed it down onto the floor as he lay down on his thin cotton bedsheet.
No sooner had his head hit his pillow than his right hand reached down and took his full length into his hand. As his eyes began to close, Callum knew just what kind of effect Libby’s body was having upon him, but there was no way that he was prepared to fully accept that fact when he needed to jerk his cock so badly. The next few moments saw Callum frantically searching his memory banks for anything that he could use to jerk off to, anything that he could convince himself was the reason why he needed to do it so badly. However, just like two nights earlier, when his eyes fully closed, they didn’t open back up as he felt his mind pulling him away once more.
After a few extended moments, Callum found himself back in the same glass box that he fantasised about previously. The glass walls and ceiling left him completely encased in the centre of the control room as he was sat on the same black leather couch as was in his living room. Unlike his previous fantasy, Callum was completely naked as his dick was just as hard and throbbing as it was in reality. However, the various engineers manning the instruments and consoles around the perimeter of the room were in a state of far greater distress.
Each of the green and amber lights surrounding the area were red and blinking in unison. As Callum turned his head to take in the scene around him, he could see that the engineers were struggling to contain the situation as various jets of steam and plumes of smoke were shooting out from various consoles and pipes. As Callum tried to focus on what was going on, the sound of an alarm or some kind of warning was ringing, although it was partially muffled by the glass walls and ceiling of the enclosure he was seemingly trapped inside of.
After he took in the scene that his mind had conjured for him, the familiar sound of Libby’s wicked giggling filled his ears as she appeared directly in front of him once more. Once Callum’s eyes locked onto her astonishing body, the chaos around the perimeter of the room couldn’t force him to look away as she was clad in a gorgeous black lingerie set. Her enhanced tits were threatening to pour over the top of the delicate lace cups of her bra, which was pushing her breasts up into a cleavage that was almost hypnotising. The thin black straps of the bra were stretched so tightly that they didn’t rest upon her smooth skin down past her shoulder, while the waistband of her tiny black G-string rose up and rested an inch above her hips. But as she crept closer to him, Callum adored the way her black thigh-high stockings clamped around her juicy thighs, with the elasticated tops only being a couple of inches long and snapping into place against her tanned skin.
Just then, the glass wall to Callum’s left went completely dark for a few seconds, before it was replaced with a giant digital clock which used enormous white font on a jet-black background. As Callum tilted his head in bemusement, the clock was set for a paltry two minutes before it started to count down.
As Callum remained seated on the leather couch, with his hard cock pointing straight up towards his torso, Libby started to shuffle closer to him as she looked into his blue eyes and spoke. “You were in such a hurry to escape this room the other night…but that’s not going to happen this time… I’m in your head, Callum… I know what you really want and that clock’s counting down the seconds until it finally happens… All of these new feelings you’re struggling with, I can understand how they can make it difficult for you to comprehend what’s going on…but you get what’s happening here, don’t you? You’re about to do something you never thought you’d ever do…and it’s going to change your whole life forever…”
Callum knew that he was lying on his bed while he was alone in his room, so made no fair attempt to cover his straining erection as the image of his sister was finally stood right in front of him. But as he pictured himself looking up into her eyes, his fantasy felt so intense as he called out in response. “I told you the last time, I don’t know what’s going on… I don’t know how you’re able to get into my head or how you’re all that I’m able to think about… I’m with Fiona, but even if I wasn’t…you’re my sister, Libby… Whatever this is…whatever my mind’s trying to show me…none of it’s real and nothing like this could ever happen in reality…”
As the clock continued to tick down, Libby couldn’t conceal her wicked grin as she looked down at his throbbing cock as she allowed the tip of her tongue to brush against her lips. “Did you enjoy me showing you those pictures earlier? All those little outfits…there’s so much more that I’m going to show you… I chose every single one of them because I wanted to get that big dick nice and hard for me… It’s only been a matter of time, Callum… Ever since you saw me walking into that hot tub in that tight fucking bikini…there’s no way that you’re going to be able to stop thinking about me… Tell me something though, if you’re so happy with Fiona…why are you thinking about me in this gorgeous little lingerie set? I’ll tell you why, it’s because when that dick gets so fucking hard…it’s because you want to feel it slide into my tight little pussy while I put these big tits right in your mouth…”
The sinful accusation only compelled Callum’s dick to throb with approval as he took a deep breath. Even hearing the fantasy version of his sister say those words out loud was enough for him to want to reach down and start massaging his hard cock, but the rational parts of his brain were screaming at him to compose himself. So much of him knew that he could never jerk off to his sister, that if he did so he’d be crossing a line that he could never return from. After he gasped, Callum looked into her eyes and replied. “If you’re really in my head, you’d know that I’ve never thought about that for a second… We can’t do this, Libby… We both know how wrong it is, it doesn’t matter how beautiful you look… It doesn’t matter how fucking hot you are… I can’t think about you when I’m like this… I can’t think about you when…”
Despite his protestations, Libby stopped him dead in his tracks as she stepped closer and straddled his waist. After hovering for a few moments, Callum’s sister lowered her hips decisively and sat squarely in his lap as she allowed herself a long glance at the clock over her right shoulder.
With just over 45 seconds remaining, the scheming redhead turned and looked her brother in the eye before she purred at him. “Doesn’t that feel better? That big hard cock is so close to my wet little pussy… You don’t need to fight this, there’s nothing wrong with knowing what you want… The way you want me to peel this bra off and for me to feel your tongue against my hard nipples… The way you want me to lean in for our very first kiss, while your hands clutch and grope at these big tits… The clock’s counting down because your mind already knows what you’re going to do… Believe me when I tell you, Callum…knowing that you’re thinking about me while you’re jerking that big dick…it’s so hot, babe… What other sisters walk around in front of their brothers like I do? All those stories about me having the wildest sex… Don’t try and deny it, you know the truth… You know that I want you just as badly as you want me… We’re perfect for each other…”
Carefully, Callum turned his head to look at the enormous clock as it ticked ever closer to zero. When only five seconds remained, Callum felt Libby’s fingertips under his chin as she turned his head to face her once again. As she looked into his eyes, her head started to lean in as she whispered to him. “I don’t care about Fiona, nothing’s going to stop me from riding your big dick until I explode…”
The words barely had a chance to register within Callum’s mind as he felt Libby’s plump lips colliding with his within his perverted fantasy. But as he lay atop his bed in reality, the moment where the countdown reached zero was when Callum was powerless to stop himself from stroking his hard length as he imagined Libby’s tongue slipping past his lips until it was writhing against his. His eyes were closed so tightly and his breathing was ragged, but the sheer pace of how he started pumping his hand across his cock signified just how complete his surrender truly was.
Within his fantasy, Libby controlled every moment of the kiss as she let her tongue delve deeply into her brother’s mouth before it slowly withdrew. As she reached behind her back with both hands until she found the clasp of her bra, she unhooked the tight lace garment with ease as she pulled the bra from her upper body and tossed it down onto the floor behind her. Once Callum was treated to the sight of his sister’s wonderful tits, with her tiny pink nipples swollen and pleading for his affections, his whole body froze as Libby leaned in and brushed her hard nipple against his lips.
While one of the glass walls had been replaced by the giant digital clock, Callum was only vaguely aware of the engineers who had left their stations and were thumping against the glass with all of their might. Each one of them was calling out to him, desperately trying to force him to come to his senses and break free of his sister’s seductive spell. But once Callum’s lips closed around Libby’s tiny bullet nipple and he began to suck, more jets of steam and plumes of smoke were released into the room. The scene had started to resemble a control room in the moments before a devastating meltdown, one where the consequences would be irrevocable.
When Libby felt Callum’s lips and tongue worshipping her breasts, she leaned down and wrapped her hand around his hard cock. Carefully, she positioned it until his bulging head was pointing upwards before her other hand ripped her tiny lace G-string clean off her own hips. It was then that she waited until Callum’s eyes opened before she dropped her hips once more and took his rock-hard dick so deeply inside her tight wet pussy.
Meanwhile, as he lay atop his bed back in reality, Callum could only process the end of his sick fantasy for a few moments before it drove him so far over the edge. With his hand jerking and pulling at his hard cock, his eyes opened wide as he couldn’t stop himself from groaning into his empty bedroom as he shot the first of many ropes of his warm seed up into the air. His heart felt like it had stopped due to the intoxicating combination of his monumental orgasm and the knowledge that he’d just masturbated to his gorgeous sister. But as his cock spasmed and shot the remainder of his cum up into the air, Callum sensed how much trouble he was in as he’d simply never experienced an orgasm like it in his entire life. Once he was able to suck down enough oxygen to think clearly, Callum was left in no doubt, whatsoever, that he was starting to lose his mind.
The following night, Callum found himself standing in the corner of a busy bar in Glasgow City Centre. It was just after 10:00 p.m. and both he and Libby had spent the last two hours catching up over drinks as they’d previously agreed to. The bar which Libby had chosen was quite trendy and popular with young professionals, and Callum only needed to look around to see that the clientele was classier than that which frequented the many different student bars across the city. However, despite it being a Sunday night, the bar was much busier than either of them had anticipated and they’d snuck off into a corner where there was the most space available.
As he was stood leaning back against the brick wall behind him, he’d taken Libby’s advice and chosen to wear a nice black long-sleeved shirt which he’d paired with his favourite light-grey trousers and black shoes. He knew that he looked good when he stared at his reflection in the mirror before he left, but when he finally saw his sister wearing her outfit in the flesh, he started to understand just how Libby had influenced him to such a degree that he’d started playing with his hard dick while he thought about her.
Libby’s gold shirt looked sublime as her long sleeves were rolled up past her elbows and the garment looked to be much tighter than it did in the preview picture. But every time the two were engaged in conversation, Callum struggled to maintain eye contact with the beautiful redhead as her shirt was purposefully designed to show off her incredible cleavage. Each time she twisted or turned her upper body, Callum was treated to the most delightful bouncing of her breasts as the tight black lace bra did its best to contain Libby’s prized new accessories. Meanwhile, whenever the hem of Libby’s tight miniskirt rode fractionally upwards, Callum was afforded a tantalising glimpse of the same black lace stocking tops that he’d pictured his sister wearing in his impromptu fantasy.
In that moment, Libby was stood facing her brother as she took a slow sip from her drink before she sat it back down on the table next to them. With a grin on her face, she looked into Callum’s blue eyes and spoke. “See? I told you she was absolutely gorgeous, didn’t I? I know she said she could only drop by for a half hour or so, but I really don’t think she’s going to be in any hurry to go back to her friends. Isn’t it hilarious though that she thinks we’re a real couple?” The comment coaxed a soft giggle past the redhead’s lips as she failed to disguise the glint in her eye before she continued. “I only need you to play along until she leaves, but you should take it as a compliment… If she believes you’re pretty enough to be dating me, that’s quite a high bar to clear…”
Despite his mind having been pulled in a million different directions since Libby walked back into his life three nights earlier, his sister’s quip was enough for Callum to start laughing as he appreciated the humour of it. Once he looked into her eyes, he replied. “Don’t get me wrong, Alicia’s absolutely amazing…she’s everything you said she’d be and more… I guess that I’m just a little surprised that she’s your type… Not that I’m saying I know what your type is…but the tattoos and the fit muscular body wasn’t what I was expecting. Fiona would kill me if she heard me saying this, but I can’t remember the last time I saw someone look as good in a dress as Alicia does…”
Hearing her brother’s reaction was enough for Libby to tilt her eyebrows in appreciation as her smile widened. After a brief pause, Libby replied. “She’s obviously hot as fuck, but it wasn’t until I started messaging her that I realised there was more to her than meets the eye. I think she realised quite early on that I respond really well to my partner taking charge of me… I’m not normally the submissive type, but when Alicia flirts…she makes it very clear that she likes to be in control… It didn’t take her long to send me pictures of stainless-steel handcuffs before she’d say that they were just for me… I wasn’t sure if we’d ever get to the stage where we’d actually meet, but when she walked up to us in that gorgeous dress…I’d knew straight away that I’d let her handcuff me to any bed she wanted to…”
Callum never had so much as a moment to prepare himself for Libby’s heated comment and it resulted in him feeling a pang of approval from between his legs. It had only been three days since he’d been reunited with his beautiful sister, but she’d made so many lurid comments that dripped with innuendo that he couldn’t stop himself from becoming aroused each and every time she did so. But as he pictured the image of Libby’s incredible body writhing in the tight cuffs as she was bound to his headboard, Callum had to shake his head briefly to bring himself back to his senses.
With his back still leaning against the brick wall, Callum responded as best he could. “You’re going to need to tell me what I’m supposed to say if she asks any questions about us. If she thinks that we’re a legitimate couple, have you told her anything about us that I’d need to know? All you told me so far is that I’m supposed to know all about how you pick up girls like her on dating apps…and I’m fine with it… Mind you, if Fiona ever brought someone like Alicia home, I don’t think I’d be able to last long enough to get her out of that dress… She looks incredible…”
After she turned her head to look towards the bar, Libby smiled as she saw Alicia returning to where they were standing with their three drinks in her hands. Quickly, she turned back to face her brother as she responded. “Don’t worry about any of that, she’s coming back over. Just follow my lead, she hardly knows anything about my supposed boyfriend. I only told her I had one because she was coming on so strong at the start, I was trying to find a way to give myself an escape route that made the most sense. But when I told her I was seeing a guy, she just told me that it made everything so much hotter for her. I’m telling you now, Callum…she’s kinky as fuck… I honestly don’t think she’d give a fuck if she knew we were actually related…”
The next hour passed as Alicia stayed much longer than she originally intended to. Once the clock moved past 11:00 p.m., the three of them remained in their spot in the far corner of the bar while their drinks rested on the table next to them. The only change to their immediate surroundings was that more customers had ventured inside the bar, which made it easier for the three to blend in.
As Callum remained in his spot leaning against the brick wall behind him, Alicia was stood facing him as Libby had positioned herself to his right-hand side. Once Alicia turned her head to address his sister, Callum had ample opportunity to appreciate the sight of the mysterious girl who’d made no effort to conceal her attraction to his sister. Alicia was the same height as Libby, standing at 5’7″, and her body was almost poured into a wonderfully tight blue dress. While her breasts were only fractionally smaller than his sister’s, her natural chest was supported by a matching blue bra that the thin straps of her dress made no attempt to conceal. Meanwhile, the plunging neckline of her blue dress displayed a cleavage that had almost every man in the bar breaking his neck to appreciate whenever she walked past.
However, as Callum caught himself staring at the girl, it was the smaller details that really added up to give her the unmistakeable aura that she possessed. Her long dark hair was deliciously wavy and afforded Alicia a carefree look as it flowed all the way down to reach the top of her tight ass, while both of her arms were almost entirely covered in various tattoos which never threatened to detract from her sensuality. Meanwhile, her plump lips looked sensational as she purposefully wore heavy makeup that made her lips and eyes stand out in the most alluring manner. As Callum’s eyes roamed across her face, he kept being drawn back to a small mole on her left cheek which accentuated her look perfectly. But as pretty as her face was, her body was undeniably world class. Her shoulders, back, legs and ass were all toned and strong, which let Callum and Libby know that she spent more than enough of her time in the gym. After Callum glanced back up and dragged his eyes back up her body, her simple black plastic choker was the perfect finishing touch as he struggled to tear his eyes away from it.
He’d only zoned out for a moment, but Callum had lost track of the girls’ conversation when he caught Alicia turning her head back towards him to speak. “You know, Callum…when Libby told me that she was seeing someone, I knew that he’d have to be quite something to hold onto a girl like that. But you’ve got no idea how relieved I was to hear that you two are in an open relationship, because once Libby sent me that first message and I saw how she looked in her pictures…there was no way that I was ever going to let her get away from me… It’s cool what you’re doing though, I haven’t been in an exclusive relationship for years. When I was on my way here tonight to meet you, I didn’t know what to expect…but looking at you now, Callum… You’re fucking gorgeous… Now I understand why Libby keeps boasting about how much time you two spend fucking each other’s brains out…”
The compliment caught Callum completely off guard, but when he tried to process the kind of things that Libby had told her about him, what they’d gotten up to in bed with each other, it sent a rush of blood between his legs. He’d barely managed to come to terms with the fact that he’d spent an entire afternoon in bed jerking off while thinking about his sister’s scalding hot body, but the very idea that Libby had told the glamorous Alicia that they’d been having sex just made Callum wish he was alone in his bedroom once more.
While his thoughts were scattered and racing through his head, Libby giggled as she stepped directly in front of Callum until her own tight cheeks were pressing against his groin. As Callum was leaning against the wall, he had no room for manoeuvre as he watched his sister look into the brunette’s eyes. At that moment, he was almost floored by the way that Libby allowed herself to lean back into him until her ass was practically grinding against his cock, before she reached out and placed both of his hands squarely on her hips. From his position, he had the perfect view to peer down Libby’s stylish gold shirt as he saw almost the entirety of the redhead’s black lace bra as it struggled to contain her exquisite breasts. Instinctively, Callum tried to drive his hips forward to create some separation, but once again Libby surprised him by playfully pushing her cheeks backwards to trap him in place against the wall.
Callum knew that Libby wanted him to play along, but he started to panic as his cock couldn’t be controlled as easily as his hands were when his sister placed them on her hips. As his eyes started to narrow, the realisation that Libby was about to feel the full force of his throbbing dick pressing against her was threatening to tear his mind apart.
At that stage, he heard Libby starting to giggle as she stared into Alicia’s eyes and spoke. “Oh, I know just how gorgeous he is…and he’s all mine… I know how lucky I am though that he lets me meet up with other girls… One of the first things he told me after we started dating was that nothing gets his big dick harder than seeing me in bed with another woman… It’s not something that we’ve done a whole lot, but whenever we have…it’s just so hot knowing how hard he gets watching me lick another girl’s pussy… All it takes is for me to have one little kiss with another girl and he’s ready to fuck me for days afterwards…”
Callum was so shocked at the bold statement that escaped past his sister’s lips, to the point where his eyes wanted to dart all over the place. However, once he made eye contact with Alicia, he saw the sultry look on her face as she was delighted with what she was hearing. As Callum stared at her, Alicia looked into his eyes and responded. “Is that right, Callum? Well, trust me when I tell you this, you won’t have to wait very long before you see your girlfriend’s tongue slipping across my tight little pussy… Libby and I have been texting for almost a month and I can’t wait to get my hands on her perfect body… I’m going to need to leave here in a few minutes as my friends are waiting on me, but I hope you don’t mind that Libby’s already invited me over to your place on Tuesday night… She’s practically begged me to bring my handcuffs with me, so I can’t wait to see how hard that big dick gets when you watch me ride your girlfriend’s pretty face… Having said that, after meeting you tonight, Callum… Just thinking about your hard cock driving inside Libby’s pussy has got me so fucking wet…”
Slowly, Callum’s jaw started to hang as he felt like he’d been separated from his senses. So much of his mind was calling out to him, silently assuring him that this was all a misunderstanding because of Libby’s insistence that they pretend to be a couple. However, the absolute conviction of what his sister and Alicia had purred at him was so strong, Callum felt like he could taste it at the back of his throat. But as shocking and as direct as Libby’s taunting was, the moment Callum dreaded had arrived as his cock was completely hard and throbbing. When he felt Libby press back against it until her cheeks brushed across his entire length, his eyes started to narrow as he braced himself for her horrified reaction.
