Standing in his best friend's kitchen, a sandy-haired, green-eyed, 19-year-old Sean Winters is wearing jeans and a blue flannel shirt over a white t-shirt. He's with his girlfriend and he just wants to go home. After all, it's well past midnight on a Sunday. Most of them have morning lecture in a few hours.

"Babe, I'm... I'm ready to go," redheaded Ella O'Connor drunkenly says, wearing a red and white outfit matching Sean's. With an arm around his waist, she tries to saucily add, "Take me... Take me home and I'll... I'll make it worth your while ... during the drive."

Short dreadlocks above a clean cut fade, Matt Collins leans against the kitchen counter. Wearing a black and white t-shirt and matching jeans, he slides his glazed chocolate eyes from drunk and horny Ella to her smirking boyfriend. "I'd take her home ... if I were you.

Tapping his fist against Matt's, Sean says, "Thanks again for the party, man. But Ella and I are heading out."

"Hey," Matt drunkenly advises, "Your sister was... Ivy was looking for you."

Sean had almost completely forgotten that his sister is somewhere around here too. The last time he saw Ivy was ... an hour ago? She was heading upstairs with the guy who had picked her up from their parents' house (they both still live at home). Scott Sanders? Or was it Scott Saunders? Sean can't remember; he only knows that the blond-haired track and field guy has no idea what kind of headache he's in for with his bitchy sister.

...Or maybe he does if Ivy has already had her fun teasing him and is now looking for another ride home.

Shaking his head, Sean sighs, "Well, if you see her again, tell her I said she can just use all the gas money she still owes me for an Uber or something. Later, man."

"Later."

Sean and Ella then make their way out of the kitchen toward the living room. And as they head to the front door, Sean's mind wanders to his only sibling again.

His fraternal twin sister, Ivy, is a petite, blue-eyed, platinum blonde bombshell with firm handful-sized breasts and a small smackable ass. The problem is that she's hot and she knows it. You see, it all makes her a complete pain in the butt. Especially to Sean. After all, she's always finding fault in everything he does. Also, she was the most renowned, virgin cock-tease in their entire high school last year. Pretty embarrassing stuff for a brother stuck in the same grade, much less the same school.

To be fair, Sean's not sure about now, though. After all, Westend College is huge and only has rumors going around about girls who actually like to put out and generally with a crowd of frat guys watching.

Virgin or not, Sean's still inwardly debating whether his sister is a slut. After all, he had once witnessed exactly what she does with guys. It was at the beginning of last year. In black pants and a red and black t-shirt, a bed-headed Sean had been in Ivy's room. He was silently trying to steal a few bucks out of her many purses and coat pockets for the gas money she always owes him.

However, footsteps in the hallway had freaked him out. So, Sean had hid in his sister's closet. In a yellow off-the-shoulder sundress, Ivy and her jeans and blue t-shirt wearing boyfriend for the day, Troy, had walked into the room seconds later. And as the minutes had ticked by, Sean hadn't been able to look away from what he had been forced to see. Not when dark-haired Troy had laid back on the bed with Ivy sliding onto his lap. And not even as the football player had pulled the top of her dress down.

With her back to the open spaces between the slats in the closet door, Sean thankfully hadn't been able to see everything. But with the mirror above Ivy's bed that thankfully only showed her face and the slow, leisure movements of what he had been able to see of Troy's head, he had seen enough. Regrettably, he had definitely heard enough too. Those wet licking and sucking sounds had been unmistakable. Especially when Troy had obviously suckled and pulled on his sister's nipples hard enough to hear a wet pop each time he had let one of them go.

Weirdly enough, Sean's dick had begun to harden even before he had watched Troy lean back and pull Ivy's hips up and over his face. After lifting the hem of her dress in the front, his sister had put her hands on her headboard. And it had quickly become pretty obvious to Sean that that bastard Troy had moved Ivy's panties to the side as well.

It was all too evident from the wet flicks of Troy's tongue that was heard crystal clear between her thighs. Well, that and Ivy's first little, "hah!" from the initial feel of Troy's spit-slicked muscle obviously running through her damp little folds. And also from the roll of her hips and the flushed and lip-biting look on her face in the mirror.

Sean's attention had seriously been split between watching her dress covered ass rocking against Troy's hidden mouth and drinking in the myriad of erotic expressions on his sister's face as she had trembled and moaned. Her heated features had gone through open-mouthed surprise to lip-curled filthy to that lip-biting pleasurably pained expression from before and back again. It had really gotten to Sean's already slowly expanding cock.

After all, he had done it to countless girls, but he had never watched one get her pussy eaten before. At least not live like that (fake shit in porn doesn't count). And especially not his own sister. And Sean had known that he should look away and be disgusted. But he wasn't. In fact, he had to fight the urge to rub his aching cock through his jeans.

But the erotic sounds of a wet tongue continuously lapping up inside of a girl's already soaked pussy wasn't doing him any favors. Neither were his sister's little heated chants of, "lick it," and "eat it."

And as she had neared her peak, Sean had even watched and heard a trembling cunt-grinding Ivy moan out, "That's it, baby.... ...Lick all up inside this wet little pussy....Go on. ...Show me just how you'd like to fuck it."

Not wanting to get caught, Sean hadn't moved or made a sound. Honestly, watching his sister getting her fuck-hole licked out and having heard her dirty words, Sean had found it hard to even breathe. Not until their mom had knocked on the door, thankfully interrupting them. Ivy had disappointingly groaned and hurriedly scrambled off of Troy. And, sitting up, Troy had simply wiped his slick lips off with the back of a hand and fixed his hair.

As for their mother...

She had been completely oblivious as she had merely warned Ivy that she was supposed to keep her bedroom door open when she had guys over.

Not caught, but still forced to leave the door open after that, a still horny Ivy and untouched Troy had just decided to leave early for their movie. Luckily, his sister hadn't needed anything from her closet before they had left. Sean's not sure what he would have done if she had caught him in there with a raging boner. And he's still not sure why he had gotten so damn hard while he had watched his sister with Troy in the first place. It had just happened.

And he had only jerked off to it once ... or maybe five times ... or possibly more. Honestly, it had been so many times now that he's not even sure.

However, what Sean's certain of is that Ivy is into some really messed up stuff. After all, the sick little shit had even kissed him, tongue and all, when she had pulled his name from a hat in a game of 7 Minutes in Heaven. It was during a graduation party at the end of last year.

Back then, Sean had been adamant about not following through with the game. He had only went into Paula Quinn's closet because Matt (wanting to bang Paula) had pushed him and locked Sean in there with his own sister as a joke. Neither Matt nor Sean could have known that a drunk Ivy would then grab him and wetly lay one on him. Sean had even pushed her away, but...

After getting a taste, the twisted little minx had latched back on and...

Well...

Sean's inebriated brain had stopped working for a second when he had heard her quietly beg against his lips, "Kiss me back? ... Please? Just a little? ...I swear I won't tell anyone about it."

Without pulling away, Sean had simply countered, "I can't....It's wrong."

But Ivy's eyes had simply trailed down to his mouth as she had answered, "So? I still want to....Please?...Just let it happen, okay?"

Sean's clouded mind had worked enough to ask, "Why me?"

And then Ivy had told him something that had both warmed his heart and made the blood run down between his legs.

"Because it's you. ...It has to be you, Sean. ...I don't think anyone else will do."

In the darkness, Ivy's messed up need for him had awakened something equally twisted inside Sean. Or, now that he thinks about it, maybe 'awakened further' is more accurate since he had already gotten so hard because of her once before.

Regardless, standing there with her drawn to him like a magnet, it had made Sean hot to know that he had somehow made his own sister horny enough to actually want to secretly make-out with him. And with a pounding heart and a little turned on, he had slowly leaned in.

Their first consensual kiss had been soft and tender ... and kind of nice. But 'nice' had quickly turned into a whole lot more, especially when he had gently opened her up and deepened their exchange. Feeling the first slide of her tongue against his, Sean remembers curling his toes and steadily thinking only two words.

So hot.

And it had been with that thought that he had picked up his perverted sister, wrapped her shapely legs around his waist, and pushed her back into the wall between two sets of hanging clothes. And it was there that he had squeezed his sister's ass while he had licked long and deep into her mouth.

He had even used his clawed hold on her rear to press her panty-covered crotch against his throbbing bulge. Tongue eagerly sliding against Ivy's, he had ended up dry-humping his own sister hard against Paula's closet wall.

In the end, he had found the situation erotic as hell. It was so wrong, but her lips had been so soft, and she had been all too eager. And his covered cock had been so hard rubbing against her satin panties with her skirt pushed up around her waist.

...Just kissing Ivy and rocking their hips together had made him extremely hot and his own sister so wet that he had quite literally smelled her arousal. With the both of them shaky with lust, Ivy's hands had been all over him as well: in his hair, on his back, and all over his ass. Near the end, his grinding had even had Ivy trembling and close to an orgasm too.

Sean knows that if they had been given just 2 minutes more, his sensitive sister would have definitely cum all over the front of both of their clothes. But seriously making out with Ivy while they simulated wall sex had only lasted for so long.

Well, it had lasted until a laughing Matt had started banging on the door. Thankfully, it had been his way of letting them know that he was about to open the hinged piece of wood. Ivy had scrambled off Sean, wiped her mouth, and merely straightened her clothes. And when they saw the light of Paula's bright bedroom again, Ivy had just strolled out and played it off like her and her brother had just been standing there waiting for Matt to let them out.

As for Sean, he had hurriedly went straight to the bathroom. He had vaguely thrown out something about having to urgently take a piss as he went. But it had mostly been to hide his erection--and so he could quickly beat his meat. Sean had cum so hard and so fast while remembering his sister's taste and touch. He still recalls how thick and copious his sperm had been as it had splashed into the toilet bowl's water. Jerking lightning fast, he had even gotten some on the rim, the raised lid, and the surrounding floor as well.

Even so, when he had cleaned up and made his way back out into the party, he had also adamantly went with Ivy's lie. And he still swears to this day that he will take it all to his grave. And he had also sworn to Ivy later that same night that it would never happen twice. Well, that and he had made her promise never to mention it to him ever again.

Truthfully, because it was so wrong, that time with his sister is still the most dirty and erotically taboo thing he has ever done. Even now. Even with a wild Ella. And he can still always fall back on the memory to get himself off quick and hard when he needs it. Especially during the nights when he's having a hard time going to sleep or when Ella blue-balls him. His girlfriend calls it edging that will make sex the next time they meet up all the better. Sean just calls it torture.

Yes, Sean knows that it's pretty sick to stroke it to what he and Ivy had secretly done in that closet. But he tells himself that it's fine as long as they never actually do it again.

As for Ivy?

Leaving Matt's upstairs bathroom and Scott Stinson to clean up the inside of his soiled boxers and pants... Well, she has been waiting almost a whole year for a chance to do erotic things with a stubborn Sean again. After all, her twisted desire for him is definitely lingering since it wasn't just born overnight.

No. Certain events have happened in the past that led up to her coming on to her own brother in Paula's closet. One has to do with a family outing and the other has to do with her best friend's older brother.

During a weekend vacation at Myrtle Beach, Sean had left Ivy alone in their shared hotel room on the first night (their parents had a separate suite). Invited by a group of random girls during the day, he had gone to a party on another floor. During the wee hours of the morning, Ivy had then gotten woken up by her brother stumbling back in. Completely wasted and blue-balled by the girl who had invited him, Sean had felt hot and in so many ways.

Forgetting that Ivy was even there, he had stripped from the door all the way to his bed. And then he had slid right under his covers....But he hadn't gone straight to sleep.

Even groggy, Ivy had soon realized what the movement under her brother's covers had meant. Too mortified to do or say anything, she had just laid there in the dark. And she hadn't been able to turn over, either, because she hadn't wanted him to look over and find her awake. So, between lowered lashes, she had just watched him. Well, she had both watched and listened as Sean's hand had worked his cock hard with quick strokes under his blanket.

...Ivy still remembers her brother's rasped chant of, "Oh, fuck" that had only gotten louder and quicker as he had continued to beat off.

Halfway through, she had watched Sean push the blanket right off his hips and naked torso. Even in the dark, she had seen that her brother's hard cock had curved upward with his bulbous head almost reaching his bellybutton. And its girth had been equal to three of her combined fingers.

Honestly, Ivy had been surprised that it was that big. And actually seeing Sean's fist sliding up and down on his thick dick, Ivy had felt her clit start to throb and her core start to ache. Too scared to move and too mesmerized to look away, she had simply watched.

And she had continued to stare as her brother's working hand had made his hips start to lift off the bed. Grip sliding down to the base of his cock one last time, Sean had squeezed himself hard. And when he did, she had watched wave after wave of thick, white ropes shooting all over his stomach, chest, and corded neck.

When he had cum, Sean had even given a strangled and drawn out, "Uuuuuungh! ...Hah! ...Ah! ...Fu ... ck," while his head had pressed back into his pillow.

Ivy had never heard that type of pleasurably pained sound come out of her brother's mouth before. And it kept replaying in her head as a sated and cum covered Sean had simply drifted off to sleep. Laying there, staring at the dripping seed covering her brothers pink and pebbled little nipples, Ivy had found herself wondering why she had felt pooled heat between her legs instead of disgust.

Unfortunately, that wasn't the only thoughts she had while laying there and staring at the spunk cooling on her brother's naked and lean body. She had wondered what he tasted like (both his cock and his cum). And her thoughts had also drifted to what he might sound like if he was awake to watch and feel her licking him clean. ...Only so she could try and get him off again, but this time with her mouth.

Fortunately, Ivy hadn't acted on her incestuous fantasies. No. She had merely decided to silently cover her filthy brother up with his blanket ... before she had rubbed her throbbing clit almost raw and finger-fucked herself back to sleep.

As for the other incident that had helped awaken her dark desire for her own flesh and blood sibling...

It had all really started after Ivy had heard her best friend, Jill, ragging on her 20-year-old brother, Kenny, for having incest porn in his browser history. She had been staying over at their house the night it had happened. It was a small affair that Kenny had fobbed off as simply being curious. The incident had died right then and there once Jill had only managed to find one single incest video link in all of his computer's nasty history.

...But Ivy's mind hadn't been able to let it go.

Later when she was in her own home, curiosity had killed the cat. Or slayed her pussy as Ivy had used her laptop in her own room to look up exactly what the fuss was all about with incest porn.

Now, Ivy was already quite familiar with regular pornographic material at this time. After all, she had been using toys to smutty stories for a while. But the first video she had watched that started out with the 'brother' secretly fingering his 'sister' while their 'parents' were in the front seat of the car...

Even though she had easily figured out that it had all been pretty much fake...

With her dildo suctioned to the seat of her computer chair, Ivy had never rode her favorite toy harder before. God, Ivy knows that if she hadn't broken her own hymen with it months before then... Well, she knows it would have hurt like hell. But it hadn't. It had felt oh so good, and it and the incest video had even managed to make her squirt all over the chair's white varnished wood.

...It was something she had never done before.

The funny thing is that, after that first video, Ivy had watched more than just sibling sex. She had even tried dabbling in a few father and daughter and mother and son plot-lines. But, although hot in their own messed up way, they really hadn't done much for her.

....Weirdly enough, though, every brother and sister video she had watched afterwards had always gotten her wet and horny as hell.

Then again, they were the only ones where her tainted brain had tried to overlay her own image on top of the female pornstar's.

And those same videos had made her slowly realize some things too. Like the male actors, her own brother's body is actually lean and nicely muscled. And from that time watching him jerking off in their hotel room, she knows that Sean's cock is equally long and thick and shoots buckets of sperm just like them too.

And the moment she realized that Sean is actually a hot hung stud... Well, instead of overlaying just her own image over the girls, her brain had also begun to overlay her brother's naked image over the guys.

And after only playing a couple minutes of the first video where it had happened, Ivy had quickly clicked off the film. But not because she had been disgusted. She had stopped the video of two siblings passionately kissing because she had gotten so turned on. Not from what they were actually doing, but from imagining that she had been kissing Sean.

...And she had liked it so much so that she had even wet her panties without touching herself.

And just like that, she couldn't hide from the truth. She was secretly attracted to her own brother. And possibly had been since watching him jerking off in their shared hotel room. Or maybe even earlier. And realizing this is what made Ivy start to change.
