Lying on her back with her head supported by the armrest, Anna shifted her legs on top of Ed's lap. Her boyfriend didn't mind her occasional moving around, so he just kept on stroking idly. They were watching TV whilst resting comfortably on the couch in Ed's and his sister Kayla's apartment.

Speaking of his sister, she was half-sitting at the opposite end of the couch. She wasn't very interested in the TV show's episode but, being tired enough from studying, she was looking for anything to pass up the time.

Anna moved around again, joking that she just couldn't find a comfortable position. The noise drew Kayla's attention reflexively. She noticed the look of adoration on Ed's girlfriend's face, and couldn't help but frown slightly. Kayla wished she had a good reason to look at her own, current boyfriend like that. Being reminded of that in her...well, her and her brother's apartment brought more frustration and disappointment than warmth and fuzziness in the stomach.

Meanwhile, Ed continued stroking his girlfriend's legs lazily. He wasn't paying that much attention to the TV show either. It wasn't anything great, nor was it terrible -- just average, mediocre. Anna seemed to enjoy it the most out of the three of them.

He glanced at his girlfriend. Indeed, she seemed fairly absorbed. His look went on unnoticed, and so did his thoughts. He was wondering, in fact, if he was doing fine as a boyfriend. Ed had high standards in every part of his life -- he was ambitious and driven just as his sister was. She was two years older than him and in her dream college, pursuing her career of choice. He intended to achieve nothing less.

Being focused on his future for the most part of his life made him a bit behind in the social department. In fact, he was in his last year of high school and yet Anna was his first ever girlfriend. Not that he had no luck with the ladies, it was just that many of the girls that were the most direct and straightforward weren't the kinds of girls he wanted to associate with. Especially not in a long-term relationship.

Anna was different from them. She was quiet and reserved. Even though she wasn't the most good looking, nor even the most ambitious, she was still courageous enough to ask one of the most attractive guys in school out. It happened a month ago.

Ed accepted, even though he didn't know her very well -- that was what dating was for, anyway. He didn't want a wild, directionless party girl. He wanted a person he could trust, depend on, and spend his life with.

She said she had a boyfriend before, but they broke up. Anna didn't want to elaborate, still hurting from the memory, but from what Ed could hear her ex dumped her for a more attractive and wild girl. Well, as Ed thought, different people mature at a different rate.

Still, as the more inexperienced one, he wanted to be a good boyfriend, to do and be his best. To a romantic relationship he provided comfort, reliance and support...among other things.

"Mmm, haha," Anna giggled as Ed gripped her legs more strongly, massaging them. "I like that."

Kayla looked at them again, frowning. It was an early Thursday evening, perfect time to unwind after an exhausting day. She had her own idea for doing just that, and not being able to do it like she needed to made her daily frustration at the fact quite unbearable. So much that she felt her dissatisfaction quickly turn to anger, which felt like a flash of fiery-hot air on her face. She quickly grabbed her phone, which was lying nearby, and typed in a simple, short text message.

She had a boyfriend of her own, god damn it. He had better be ready to step up.

"I'm going out," Kayla stated simply as she stood up and headed to her room.

"Alright," her brother answered, without looking at his sister.

He didn't wonder where she was going. She was old enough to do whatever she wanted, after all. Besides, he knew her well enough to know she could take care of herself, her being his sibling and all. Ed very rarely had any arguments with Kayla, and they often understood each other implicitly. They knew each other's personalities and quirks, strengths and weaknesses. They helped each other out and knew they could count on themselves no matter what. Very few siblings got along as well as they did.

Truly, the decision to share the apartment as roommates was one of the best they could've made. It was a fairly sizable one, which their rather wealthy parents paid for, so they could live closer to the center of the city and focus more on their education.

As Ed continued idly stroking his girlfriend's legs, making her mutter appreciatively every now and then, Kayla was dressing up in her room. She switched her comfortable, indoor clothes for a pair of tight jeans and a fresh t-shirt. It was very warm this time of year, so she didn't need to wear anything more. Afterwards she added just a touch of make-up of a blood-red lipstick and a slight eye shadow, and finally fixed up her dark hair for an enticing, fully side-swept style.

"Damn, I look good," she said to her reflection in the mirror, as she blew herself a kiss. She knew she did.

There was no vanity involved in a statement like that, because Kayla was drop-dead gorgeous. Full, pouty lips, hazel-colored, bedroom eyes, cute, upturned nose, high cheekbones -- you name it. Both she and her brother were fully blessed with astounding genes and they did not squander their potential by not staying in shape. Sometimes they even exercised together, although mostly they kept their own training regiments.

As such, Ed's sister had a killer body. He was a tall man, and she, while a head less so than him, was also on the taller part of the spectrum. She twisted around as she inspected herself in the mirror. She was as fit as an athlete, and as attractive as a supermodel. She stood up on her toes, her muscular legs holding her steadily and gracefully, flexing her mouth-watering, juicy ass. When she tightened her muscles and lifted up her shirt, there was a visible outline of her taut abs.

She worked hard for it, and it showed. And, despite all the fat-burning exercise, she kept her two most eye-catching features.

Kayla was busty. Very busty. She had a cup size that many porn stars paid a lot of money to get. And yet she didn't pay a dime to fake, because she was naturally born with it. Her tits weren't just big, either -- they were as perky as the rest of her body, bouncy and springy whilst remaining deliciously soft. Two small, cute nipples tipped her heavy boobs, fulfilling the sexy, seductive picture as if straight from a wet dream.

She frowned at her irresistibly attractive reflection. Kayla was torn about being this sexy. To her, sex appeal this heavy was a curse in its own way. She shook her head, grabbed her purse and headed for the door. Moments later she passed the loving couple on the couch.

"I'm going, see ya later."

"Yup, stay safe," Ed told his sister, once again not sparing her a glance.

Anna, however, did spare Kayla a glance. A glance that bespoke uncomfortable, ugly-colored feelings which spread like poison in her stomach. A jealous and envious glance. The attractive young woman felt it, as strong and directed as it was, but spared no mind. She had her own interests, and bothering with some other girl's insecurities wasn't one of them.

Unlike his girlfriend, Ed was quite used to his sister. He did of course know she was very attractive to the opposite gender, but he wasn't attracted to her himself. Why? Because, obviously, she was his sister. They shared blood and genes. It being a taboo in modern society was another matter entirely, but not altogether to be ignored.

As such, when most men would downright stare with their jaws hanging out staring at Kayla's massive, heavy rack, Ed was unfazed by women's big breasts. He grew up around his sister, and after many years he was just used to them.

And so, soon after, the tall, handsome boyfriend and his girlfriend of one month were left alone in the apartment. And it wasn't just Kayla who had her ideas about unwinding.

In a quarter of an hour, Ed's slow massaging turned more and more intimate, distracting the young, infatuated girlfriend away from the show. His hands were squeezing less, and sliding more, all throughout her legs and especially on the insides of her thighs.

She giggled every now and then, calming herself down with humor as arousal glazed her eyes, as her heart beat faster whenever Ed smiled and gently positioned her legs to put more weight against his increasingly more pronounced bulge.

They had their first time quite a while ago, and because of that Anna knew what to expect. It was why she was getting this hot, after all, buzzing with pink-colored arousal radiating from her heart and groin throughout her whole body.

Some more minutes passed until the young, lovey-dovey couple just had to retreat to Ed's bedroom.

//

Kayla was furious. It showed in her aggressive, forceful steps, in her angry scowl, in the way she slammed the door to her apartment. She threw her purse angrily, too consumed by her rage to notice anything. After all, she had just broken up with her boyfriend.

'That lying, wimpy piece of crap,' she kept thinking. She poured herself something to calm down, but it didn't help much.

It was always like this. Every fucking time. She finds somebody she's interested in, someone that just might be able to make her happy...and every time she ends up disappointed.

"God fucking damn it, fuck," she kept on muttering curses in between breaths.

It took a while, but she began calming herself down. Deep breathing, clearing the head from unproductive thoughts, steady drinks from something cold...all seemed to help. She needed a calm mind, as always, but...she was still human. There was a limit, and she had reasons to blow some steam.

As her hot, boiling anger receded, as if burning grass leaving black, lifeless ashes in the flame's wake, so did she begin to feel empty. She was angry, yes, but that did not help her feel any better, merely to enable her to swallow her disappointment.

It seemed she would have to, as she always had to in the end, take care of herself on her own.

But, then...

"Aaaah! Oh my gooood, baaaby!"

Kayla froze, surprised. The feminine moan she just heard startled her.

'What was that?' she thought to herself.

At the new, unexpected turn, she had gotten distracted from her internal distress. Her focus shifted, and she started hearing...noises.

Clearly sexual noises.

Her eyes widened, her mouth opened in an O-shape. Was that...what she thought it was?

She began walking, or rather sneaking towards the source of the noises. She felt her cheeks turn red and smile turn into wicked surprise. She knew her brother never caught her having sex or anything like that, nor did she catch him. They were rather discreet about those kinds, staying out of each other's way.

Until now.

'Seems I got him first,' Kayla thought to herself with amusement. 'Let's just...see how's my little brother doing, hm?'

The noises grew louder and louder behind the closed door to Ed's room. His sister came closer and closer, until she finally ended with her ear against the smooth, wooden surface.

"Oh my goood...Ed...oh my gooood!"

Kayla listened on. Her surprise, which shifted her entire focus onto her brother having sex with his girlfriend began turning, through curiosity...to interest.

There were rhythmic, loud slaps of flesh against flesh, and just as rhythmic sounds of honest, feminine appreciation.

'Wow, she's loving him...he must be going at it real hard,' Kayla kept thinking. She couldn't help, but wish...despite the slight sense of wrongness that came with the thought...that maybe, just maybe...she wouldn't mind being pounded like that herself.

After all, the whole reason she felt frustrated day in, day out, breaking up with one boyfriend after another...why she broke up with her current one and came home fuming with anger and disappointment was...

Kayla needed to get laid. She needed to get fucked hard, like a slut. Like a whore. She was ambitious and her college wasn't the easiest, it was full of stressful crap. She persevered, but not without pressure leaving its toll. Furthermore, besides being and feeling hot and fuckable, she was in her prime. She had always known party girls, getting it wild and crazy regularly with random guys, but she stuck to working for her future and career.

She thought those girls were making a mistake, that there would be time for later. Perhaps that was true, but secretly...Kayla envied them. They might've been making a mistake, but even though they didn't even come close to being Kayla's irresistible level of sex appeal...they were getting nailed by studs all day.

Anybody Kayla found just couldn't fuck her like she needed. She was hot, sexually aggressive and demanding. She knew what she wanted. But guys just couldn't control themselves around her...as if she was just too hot for them.

And so she felt sexually frustrated for as long as she could remember. She was bored with masturbating herself to the same old orgasms. She was bored with lifeless toys. She just needed a real man to use her like a slut. She needed a real man to fuck her like she wanted.

But, at this very moment, it wasn't Kayla who was getting fucked. Despite the hot and sexy woman deserving it so bad, it was Anna who was having the time of her life.

Kayla knew Anna, and she wasn't impressed with the young girlfriend. She didn't seem to have any major drives or motivations, she was quiet and, frankly, spineless. And she definitely was nowhere near Ed's league when it came to attractiveness. Kayla told her brother he could do better, so much better...but he didn't listen.

And yet this undeserving, plain and boring girlfriend was in heaven, while Kayla was in hell.

As she listened on the moans of unbelievable pleasure, Kayla wished and wondered. Wondered how Anna must be feeling right now...wishing it was Kayla feeling that.

'If only I could find someone like my brother...' she mused inside herself.

She closed her eyes, and listened to the noises of hard, intense sex. Her interest turned onto arousal as she fantasized about being fucked as well as Anna was. They must've been going at it for a while now, and yet it was still so intense.

Kayla didn't feel very illicit, or naughty...she didn't think about it. She was just so, so fucking horny. Her hand slipped between her thighs, where her young, neglected, tight, dripping wet and boiling hot pussy's muscles contracted and relaxed, wishing someone would just stretch them for a while...some hunky man with a rock hard, throbbing cock...

"Oh, god...Ed...oh my god, I love you...I love you so much! Ahhh! You're like...ohhh...splitting me in two, baby!"

Kayla moaned in unison with the oblivious girlfriend. Ed's hot, naughty sister wished so hard she could feel the same.

She was so horny now...as if her anger's scorching, black flames died out instantly, their smoking remains turning into glowing rays of curiosity, drawing her attention to this enticing show right behind Ed's room door. And then, hearing such promises and announcements of pleasure, the rays reversed, heading straight into her innermost, neglected depth...melting them like the Sun does snow...turning the dripping wetness into liquid pleasure and arousal.

Kayla couldn't help but fantasize...just a bit...that it was her being fucked. That it was her entranced in a heavenly state of pleasure and ecstasy. That it was her moaning her stud's name...Ed's name.

She gripped her pussy strongly. It felt so wrong to...fantasize about her own sibling. Her hunky, ripped brother, throwing a fuck of a lifetime into his hot, sexy sister? Her eyes shot wide, and her throbbing pussy blazed with arousal and pleasure.

She didn't know why she was feeling like it...like the horniest woman on Earth. Whether it was just her pent-up arousal, her rollercoaster of emotions...or the illicit taboo that was so fucking appealing.

Kayla wanted to see it. She didn't want to fantasize anymore, she didn't want to wish...she didn't just want to hear, she wanted to see it.

She wanted to see what a real, intense fuck-session looked like.

Her heart was beating like a jackhammer, her blood was rushing so hard she could almost hear it rushing in her arteries. She bit down hard on her lip, rubbing her blazingly aroused pussy fiercely.

She slowly pushed down on the doorknob. Then she pushed forward, trying to make it as slow and as quiet as possible. And then she saw it.

Her brother was naked, with his back at an angle and towards the door...towards Kayla. She couldn't help but notice how defined his muscles were, glistening with sweat as he fucked his girlfriend doggy style.

Anna was lying down as much as she could, just taking it. Only her behind was up, while her arms lied motionless as she was leaning on the side of her face. She appeared too exhausted to move.

'Oh god,' Kayla thought.

That was it. That was what she wanted to feel. Too exhausted to move...too exhausted to think...too exhausted for anything but feeling her body melting in an ocean of lustful emotions and sexual pleasure.

It was too much for the sexually frustrated sister. She couldn't pry her eyes away from the hot spectacle. Desperate to cum, she pulled and tugged on the jeans, trying to take them off as quickly as possible. Moments later Kayla moaned as her fingers sunk into her hot, tight pussy. She felt it squelching lewdly as she pleasured herself in tandem with her brother's intense fucking.

Her horniness and arousal were sky high. The taboo of masturbating as she fantasized about her brother nailing her, his own, hot-as-fuck sister to the bed turning her on something wild.

She watched the undeserving girlfriend and felt almost determined to step in, kick her out and take her place...letting her handsome, studly brother fuck someone attractive for a change.

'Oh, god, brother,' Kayla thought to herself. 'I want you to fuck me like that...so bad...'

"Ed! Ah...ah! Ed, I'm going to...I'm going to cum!"

"Cum, baby. I want you to cum," Ed cooed. His voice was smooth, strong and tense. He put in real effort to prove himself as a lover.

Kayla's eyes were wide open as she stared at her brother. She couldn't believe how aroused she was. When her brother told Anna to cum, Kayla felt...like he said it to her.

She felt she had to reply...quietly if nothing else.

"Yes...fuck, brother...make your sister cum!" she stifled her voice, biting her lip hard.

"Cum for me. Show me how much you like it," Ed commanded.

"Fuck, fuck, fuck!" Kayla answered on tight, short exhales.

"Aaaaaaah!" Anna moaned.

Kayla felt her dam breaking, and all the feelings and emotions that were boiling inside her exploded. Her pussy flexed and throbbed, dripping wet as she felt a strong orgasm rip through it. The hot, horny sister felt as if not able to handle all her pleasure...as if her hunky brother forced some to it to spill out. She cursed and cursed, inhibiting herself to not vocalize her pleasure and alert her brother to her presence, riding out her orgasm.

As noises, and overwhelming waves of pleasure died down, Kayla realized what precarious position she was in. She just fantasized about incest, about fucking her brother...and loving it.
