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…
