But She's My Sister...

The following story contains themes of incest. If that's not your thing, please feel free to read something else.

Sophie stretched out and let out a soft yawn. It was the type of yawn you made when you had absolutely nothing else to do but bask under the hot, July summer sun. A few streaks of clouds decorated the vast blueness of the sky above, and a gentle breeze kept the heat at bay. But despite the warm day, a shiver ran down her spine. She shifted uncomfortably on the hard pool chair. "I feel like I'm naked,"

Amy rolled her eyes. "That's the point genius. It's supposed to turn you on,"

"Breathing turns you on," she shot back. And she wasn't entirely lying. Amy was her life long best friend that also happened to be the biggest slut she had ever met. For Amy, having sex came just as naturally as it was for Sophie to brush her teeth every night before bed. And as much as she loved her friend, she could almost shudder at the prospect of fucking so many boys. Coming from a conservative christian family that came with its conservative christian beliefs, she had been made to believe that sex was supposed to mean something more than a one-night stand. And after her most recent break up, the young man who had been fortunate enough to take her v card had left her bearing a personal grudge against the entire human male species. And that had been 3 months ago.

"Come on, just relax," drawled Amy. "Your folks aren't home for a few weeks, it's your summer break from college, just-"

"-relax. I know," Her friend was right. She was no longer a kid - she was 19 and attending college, and while her parents would still throw a fit if they saw her prancing about in the bikini Amy had gotten her, she had the right to wear whatever the

fuck

she wanted. And besides, they weren't even here to tell her off. Consciously, Sophie eased her body and settled into the sun lounger. It was her first time wearing almost nothing while she lounged in her backyard for all the world to see.

She considered herself to be relatively tall, and relatively athletic after having been a track athlete back in high school, she liked her dark black curls well enough, and there wasn't much to complain about her high cheekbones and slender jawline. She thought it gave her face some ferocity. But to anyone else, it was immediately apparent that Sophie was an absolute stunner. Blessed with perfect genes, she was every teenager's wet dream with a bust that simply overwhelmed the rest of her sinewy frame. While her 'girls' often took centre stage, she wasn't lacking in the department below by any means either, with a graceful but equally sexy set of curves sculpted by her countless hours at the gym.

And as much as she hated it, her friend was right yet again. Lounging in this atrocious piece of swimwear, knowing her middle-aged single neighbour could be peeking through his blinds at this very moment, was a slight turn on.

"You know what you're doing is weird right?" Alex nervously cracked his knuckles.

"...huh?" Dunley was too engrossed with the task at hand to pay him any attention. The blinds had been slightly parted, and in his hands, he held a pair of binoculars.

When Alex found that he couldn't crack his knuckles anymore, he spoke. "You're watching my sister...sunbathe through my binoculars."

"Yea," shrugged Dunley like it was a perfectly normal thing for 2 eighteen-year olds to be during their summer vacation.

Silence filled the room, and Dunley finally looked up. "Here, take a look"

"She's my sister dude, we've been over this already"

Dunley sighed annoyedly. "Just one look, don't be such a killjoy," He held out the device, and Alex took it uncertainly. He tried to think of something to say but Dunley's impatient expression made him yield and press the device against his eyes. The world suddenly shifted, and his vision had zoomed in on a figure lying on their lounger. And then he noticed the bikini. It was a red little thing which was really just a bunch of string with a few patches of fabric thrown into the mix for good measure. His eyes subconsciously travelled up her long legs to her luxurious thighs before giving in and snapping onto her chest. The flimsy bikini struggled to contain her bust, leaving much of it overflowing- "Alex?" Dunley had a sly smile playing on his face.

"I didn't think she'd ever wear something like that," He had only seen his sister in a bikini a few times, and everytime she had worn something an 80 year old woman with 4 grandchildren would wear, and certainly not this new ultimate slut bikini.

Dunley stood up and dabbed him. "Alright, it's time I fucked off. Remember what I told you?"

"You were never here,"

After Dunley had taken his leave, Alex slumped down on the couch. Out of habit he booted up the playstation and opened up GTA. Dunley was the only 'true' friend he'd ever had. He could be a little...different...when Sophie was around but they'd also spend hours grinding League together, talk about girls, and do what other normal eighteen year olds would do. They were both your typical virgin, female repelling nerds that no one wanted to be seen with at lunch, and while Dunley could probably lose more than a few pounds, Alex was skinny to the bone. No amount of eating or working out would get an ounce of muscle in him. They often joked about being destined to die as virgins, but lately, it didn't seem that funny.

The deck doors slid open and Sophie came in with a towel wrapped around her waist. He glanced up. "Don't let Mum and Dad catch you walking around in that,"

She flopped down next to him. "They'd never know unless someone here decides to be a little bitch,"

Alex looked offended. "Come on Sophs, when have I ever snitched you out?"

"Remember that one time at the-"

"Airport? Yeah," he smiled, pausing the game. That had been a long time ago.

"Time flies," she sighed. It had seemed like yesterday when she would run around with her brother, pulling stupid pranks at every possible opportunity. But here she was back from college, and Alex was almost done with high school.

His gaze momentarily flitted down to her chest and immediately scampered back. What he had seen with the binoculars was true after all. "College turned you into a real bimbo huh?"

She punched him lightly. "This bimbo got into Westminster." The move had made her tits jostle, and their motion had not gone unnoticed by him.

A grin broke out on his face. "The one that offers a course on pornography?"

"Maybe you should take it, sounds perfect for pervs like you,"

"You're assuming I need to," He wasn't joking; if there ever was a quiz night on pornography, he'd probably bring home first place, although his parents would probably put him up for adoption the next day.

"Ugh" She wrinkled her face in disgust at the TV. "Aren't you tired of playing the same thing?"

Alex shrugged. "Nothing better to do,"

"Go out for once. Touch some grass, ask your friends to come over,"

"I don't have friends, plural. I have Dunley, and you don't like him." It was a statement, not a question, and his face had lost its joy. His social life was always a touchy subject.

"What? I never said I don't like him," Sophie put on a face of outrage, but she could feel his eyes see through it - they knew each other too well. If she was being honest, the overweight kid with his greasy hair who probably showered only when there was a full moon, gave her the pervert creeps. "Look, it doesn't matter whether I like him or not. He's your friend, and if you like him, that's all that matters."

The boredom he had initially felt had vanished, and the day ahead looked much brighter for some reason. "Thanks, I guess"

#####

Alex heard his sister come in through the front door after her evening run. He waited patiently until she had gone into her room, and as soon as he heard the soft hum of the pressure pump come on, he grabbed the horror mask he had hidden under the couch. It had seen much use over the years, but somewhere down the line he had forgotten about it until he had discovered it this morning. When they were younger, he had always come up with new ways to jump-scare his sister, making her shriek and chase him around the house while he laughed his head off.

Alex made his way upstairs and knocked lightly on her door for good measure. Seeing that there was no response, he gently eased the door open and shut it behind him. The shower was running steadily in her ensuite. As he looked around the room, reminiscing of all the fun times they had during their childhood, the half open laundry bin caught his attention. Out of bored curiosity he innocently peeked inside and found her undergarments from that evening's run shoved in. And before he knew what he was doing, he had pulled out the black sports bra and begun to feel its fabric. Alex didn't need the label that read 32DD to tell him that his sister had a big rack, but the little piece of private information made his crotch tingle, nonetheless. Too far in, he picked up the matching panty. It was still damp with her sweat...and whatever else. Alex could feel something stirring inside of his dick. He lifted the undergarment to smell it, but a little voice in his head stopped him in his tracks.

What the fuck was he doing?

This was his sister of all people. Ashamed, he hastily shoved it back in the bin.

The shower was still running, but it wouldn't run forever. Alex pulled the mask over his head and slid under the bed with ease. Guess that was one perk of being awfully skinny.

After having dried herself, Sophie stepped out, wearing nothing but a cloud of steam from her shower. It had been a long day and the evening run had left her tired. She grabbed her pyjama's, donning the thin pair of silky, lace trim shorts and a simple t-shirt, which was loose but short, and only made much shorter by her breasts, leaving a good chunk of her midriff visible.

She walked over to her table and was about to pick up her phone when a hand grabbed her shoulder. "WRAHH!"

Sophie shrieked. A jolt of sudden fear ripped through her and she spun around to face a long-toothed monster. She shrieked harder.

Alex ripped off the mask and burst out laughing. It had worked like a charm.

Unfortunately, Sophie didn't find it as amusing - far from it. "Alex, you fucking incel!" She charged at him with the intention of giving him a piece of her mind, but having expected the move, he dodged her easily and ran out and down the stairs with Sophie hot on his heels, still laughing. With practised ease he jumped onto the landing, skipping a few steps, and jumped the last 5 steps.

Alex looked back to find her sister having a much harder time running down the stairs with her unsupported rack wildly joggling about. The sight had made him pause momentarily, and that was all Sophie had needed to pounce on him. They crashed down onto the floor and wrestled the way they had often done years ago.

Her fury was still shimmering hot. "It's not funny Alex!"

"You're kinda heavy, " he wheezed, still smiling. She had managed to come on top and had him pinned to the ground with her body.

"And what the hell were you thinking when you hid in my room?" Alex had to admit that his sister looked cute when she was angry. Scary too. "Are you even listening?"

"It's kinda hard to focus when I'm being crushed to death," he rasped.

"I was naked in there you perv,"

"I swear...I didn't see anything. I was...under your bed," The smile had left his face. "I swear,"

The anger vanished, just as fast as it had appeared - it had only been an innocent prank, the type they'd pull off on each other when they had been kids. So why was it any different now? She grew conscious of her position and untangled herself and stood up to adjust her hair.

"You almost killed me," complained Alex.

She shot him an angry glare. "Serves you right," She felt bad for having overacted, but it was not within her to apologize. Instead, in a gentler tone she asked, "You wanna watch something together?"

"As long as you don't smother me,"

Sophie rarely went around the house without a bra, much less her night clothes. For one, her mother would not allow it, and her dad would disapprove by averting his eyes in discomfort. But they weren't here to tell her off, and she had already settled down on the couch and didn't fancy a trip all the way back upstairs. The TV cast a bluish hue against the rest of the dark room as

The Ugly Truth

played on Netflix. But as the night got colder and the scene with vibrating underwear came on, she wished she had dressed more appropriately. The chill among other things had made her nipples harden and the t-shirt did little to conceal the outline of her chest. She hoped it didn't bother Alex who sat next to her.

Don't make it weird. He's already seen you in that god-forsaken bikini remember?

She was right - this was her brother, who was she kidding? Relaxing, she snuggled up and leant against him. His skinny frame stiffened and slackened a moment later. It was warm and bony, but comforting nonetheless.

"I'm sorry for scaring you earlier." He spoke softly.

It wasn't everyday she got to hear her brother apologize, and his sincerity reached her heart. He could be an uncaring rascal on the outside, but deep down, she knew he was just the sweetest, harmless, innocent boy he had always been. "Don't be. I missed your jump scares,"

"Missed you too Sophs," That was all Sophie had needed to drift off to sleep in the middle of their movie.

Once the credits had started rolling, Alex realised that his sister was already fast asleep. He had been sternly ignoring the graze of her right breast on his arm, and it was time he moved. He gently eased her head onto the couch and went up to bring her a blanket, knowing she would have done the same for him.

He moved to cover her up with the blanket in his hand but stopped. He had avoided gawking at her before, scared that he might get caught in the act, but his curiosity had grown impatient. When he had been hiding under her bed and watched her cute feet walk around, it had sent a thrill of excitement through him knowing she was completely nude. A simple peek would have let him glimpse what treasures she possessed, but fortunately he had managed to keep those intrusive thoughts at bay.

Alex had switched on the lights, and he could now clearly see her figure, sleeping peacefully on the couch. Despite the t-shirt being loose, gravity had pulled it onto her chest and he could make out the dark outline of her nipples gently poking through. He moved in for a closer inspection and as he stood there, blanket in hand, it occurred to him that his sister was a woman. It was a strange discovery and before he had always seen her as just his 'sister', as if the two were somehow mutually exclusive. She had actual breasts, and quite an impressive rack at that and what looked like a killer ass in those lace trim shorts. Dunley had been right, she was hot. But she was still his sister.

Get your head out of the gutter Alex

he berated himself, and finally covered her up with the blanket.

Another day, another session of tanning. Except this time, Amy was out for the day. Probably getting railed by some guy, she mused. Truth be told, Sophie was bored. And horny. Which was a potent combination that she was all too well aware of. Her folks were out for a few weeks, and she had intended to make the most of this rare freedom but had so far failed to do so. It had been a long time since she had last had any steamy action with a guy - too long. Sure, she could hit up someone, get her ass handed to her. But after her recent break up, she didn't think she could stand another guy. But unfortunately, that didn't stop her from being horny, which sucked.

"Sophs, I'll be out for a while," called out Alex from inside.

She couldn't remember the last time she had had the entire house to herself. "Sure," she yelled back. She could feel the thin straps of her bikini cut into her slender shoulders as it attempted to contain her bust, and the little G-string left very little to the imagination. Against her wishes, her hand had begun to crawl down, and it wasn't long before she found herself slowly and subtly but surely rubbing her desperate snatch through the fabric of her bikini. The G-string quickly grew damp under her touch. An idea suddenly found its way inside of her. An idea so crude that she felt disgusted with herself, and yet, there was no denying its excitement.

Leaving the thinking for later, Sophie found herself going up to her bedroom on autopilot. She opened her wardrobe and rummaged through its contents before finally finding it. With its packet still intact, was the vibrator she had been given for her eighteenth birthday by Amy. Back then, she had no use for it, and as silly as it sounds, she had been too scared. She believed she was on the more sensitive side of things. Yet, without hesitation, Sophie ripped off the packet, and held the well-built device in her hands. It looked expensive and felt expensive. There was even a small remote control that had been included.

Real neat Amy.

After confirming that it worked, Sophie made her way back down. She wasn't planning on doing it in her room -that would simply be too vanilla. With her heart racing, Sophie pushed herself up onto their countertop. The large marble countertop was where they had breakfast every morning with everyone seated around. Before her thoughts could knock some sense into her, she tugged the G-string aside to reveal her clean shaved slit with its lips flared up and moist, drooling for what was about to come. The chunky vibe took some time and effort to disappear into her unaccustomed opening which had seen very little use, but her growing wetness helped. She undid her bikini top, and appreciated the way her tits sprang out eagerly.

Swinging her legs up, Sophie lay down. The marble felt cold and unyielding against her supple body. Taking it slow, Sophie dragged her hands up her waist, passing her toned midriff, the ridges of her ribs before the slender terrain unexpectedly changed as her hands met her firm but large breasts which rested heavily against her chest. It had been a while since had gotten this worked up. Pinching her nipples, she attempted to palm them, but try as she may, her hands were too small for the task. It was time then. Using the small remote, she switched on the vibe, and it obediently sprang to life.

Holy shit, this is a hundred times better than my fingers.

The water works had begun, and she could feel her juices dripping down the already drenched G-string. What would her parents think if they saw her grooling on their expensive countertop where they had breakfast together as a family every morning? What would happen if her brother came back and saw her moaning and squeezing her tits in the middle of the house? The last thought sent an unexpected tingle down her body as it dawned on her that she could be caught any moment.

Alex had been half-way up to the local game-store when he realized he had left his wallet, and Apple pay was only convenient when you had money in your account. Kicking a nearby stone in frustration, he cursed and turned back. The last few weeks had sucked. With school closed for the summer, he had quickly grown bored, and even some his favourite games had failed to keep him entertained. 7 Hours of league of legends could quickly turn pretty sour. He had expected things to get better once Sophie came back from college. But she had changed. She was no longer the older caring sister who had always worn baggy t-shirts and loose shorts around the house, running around and teasing him. Once their parents had taken off on some business trip, that ungodly bikini had come on. The first time he had seen it, he had nearly lost it. After that day, he had begun noticing things that had previously gone unnoticed - the way even her baggiest t-shirt failed to hide her nipples from protruding when she went braless around the house, the way her chest moved when she came down the stairs...It was driving him mad.
