Lucas was lying naked on his bed, slowly stroking his cock, as he imagined it was someone else's hand jacking him off. Like most days, his mom was at work and his sisters were at cheerleading practice. He closed his eyes and pictured Sophia Berkshire, captain of the varsity cheerleading squad, she was about a year younger, but way hotter than any of the girls with whom he had graduated. She'd been best friends with the twins since forever, and had slept over countless times. Lately, the girls' pajamas had gotten more and more revealing. More often than not, he thought about her creamy skin under satin, or the beautifully budding breasts under her cheerleading uniform. Her long, slender fingers wrapped around his throbbing cock, sliding up and down as her naked breasts swung with the motion. And she would bend down and take him in her mouth. Lucas began cumming, sliding his hand over the head of his cock and using the cum to stroke his orgasm to completion.
That's as far as his fantasies ever got. He'd never even seen a girl naked in person, much less touched a breast or had a girl show any interest in him sexually. He'd been allowed to date for years, but he never quite managed to ask anyone out, let alone land a girlfriend. As he grabbed a towel and started cleaning up, he heard the door open as Emily and Elisa got home. He'd taken a lot longer than he'd thought. That had been happening a lot lately. He quickly wiped up and threw his clothes on, laying back down on the bed.
"Wake up, dork."
"You're always sleeping. It's not like you do anything."
Lucas opened his eyes to his sisters standing over him. They were identical twins, and he was one of the few people that could tell them apart. Well, until recently anyway. When they'd turned sixteen, they were allowed to start dating, just like he had been, but in the two years since, they never seemed to have the time. He guessed they wanted some individuality. Emily still wore her dark brown hair long, but now it had layers, which, meant almost nothing except that it looked really good. Elisa had chopped hers off, shocking everyone. It barely reached her shoulders, now, and did this flip out thing at seemingly randomly spots. She was beautiful. They both were, actually. The guys were probably killing each other for the chance to get close, but the girls always focused on school and cheerleading before anything else. Their green eyes, and milky white skin had always gotten them attention, but now their breasts were becoming very obvious under their uniforms.
Realizing that he was getting horny again, and that it was because of his sisters, he forced himself to focus. He shrugged up at them.
"I guess it's just boredom. I was about to hop on the computer and game a little." Which was half-true, he was going to look at porn, but never got that far.
"Well, mom called. She'll be late again, so we're on our own. If you run to the store, we'll cook.". She handed him a slip of paper.
"Sure, sounds better than cereal or frozen pizza."
It was a little weird that they'd be so eager to help, but not so much so that he thought twice about it. They'd all always gotten along. After their dad left, they all banded together, and made it through the ordeal. The girls just didn't have the same interests or friends that he did. What few friends he had anyway. They always got along, but they simply never had anything to fight about.
The girls went into the next bedroom, which they still shared, and probably would until they went off the college. Lucas was attending the community college while he worked part-time. He doubted he'd be able to move out anytime soon. As he opened the door to leave, he realized he had forgotten his wallet, and went back to get it. From down the hall, the twins hadn't closed their door all the way and he could hear them talking.
"We've got maybe half an hour, so we can't get too carried away." While he could tell them apart by looking at them, Emily and Elisa sounded exactly alike.
"Okay, but, I want to taste it again."
Are my sisters doing drugs? He thought to himself, creeping down the hallway. As he peeked through the cracked door, his eyes widened, seeing the twins taking off their shirts. Emily leaned in and kissed Elisa on the mouth. He could see their tongues working around each other. His cock immediately began straining against his pants. They worked each others bras off, and at the sight of their milky white breasts he almost exploded in his boxers. Terrified of being caught, he got his wallet and slipped quietly out the door.
All that night, he couldn't stop thinking about what he'd seen, and even got caught staring at the twins' chests, though they didn't call him out on it. He jerked off twice that night, picturing his topless sisters making out.
The next day, he got out of class and rushed home to jerk off some more before the girls finished cheer practice. He looked up some twin porn on the internet, but, he barely looked at it, closing his eyes to picture his sisters. He felt somewhat guilty about his thoughts, but couldn't help himself. They got sexier every time he thought of them.
"We're on our own again." Elisa announced, when they got home.
"I gotta drop off some notes with my lab partner, but if you want to repeat last night, I can grab some stuff on the way home." At that, the girls smiled at each other, and Lucas knew what kind of repeating they were thinking about.
As they went into their room, Lucas opened his window a crack, and popped out the screen. Luckily, they lived on the first floor. He let the door slam behind him. And walked around the building. Making sure no one was looking, he snuck through his window, and replaced the screen. In the hallway, he couldn't believe his luck, the door was cracked again.
The twins were already topless, and Elisa had her mouth on Emily's nipple, sucking and licking it while Emily moaned and ran her fingers through Elisa's hair. Kissing her way down Emily's smooth, flat stomach, Elisa worked Emily's skirt and panties off at the same time.
Lucas could barely breathe. He couldn't believe what he was seeing. This was so much more than he could have hoped for. He freed his throbbing cock and began stroking it, his eyes fixed on Emily's beautiful pussy. She was shaved, and her lips were smooth. It was already glistening with her wetness when Elisa began licking all around it, and then dipped her tongue inside her twin sister.
"Oh, oh, oh, oh god. Please! Lick my clit.".
Elisa obliged, driving her mouth down just above Emily's dripping pussy, who arched her back and grabbed Elisa's hair in her fists.
"Oh fuck, fuck, yes, eat me, Ellie. Suck my clit!" Elisa slid her hand inside her skirt and started fingering herself as she worked Emily's clit. Eagerly, the girls squirmed, any skill or finesse overlooked in the overwhelming urge to feel pleasure.
Lucas braced his hand against the wall as he stroked his cock, his cum surging as his orgasm approached. He realized his error, when Emily looked up at the motion.
"What the fuck! Lucas!" Elisa's head whipped around and she, too saw her brother, frozen outside her door, hard cock in hand, before he bolted into his room, and locked the door.
Breathing heavily, all thoughts of masturbation fleeing from his mind, he couldn't even begin to think what the consequences of this might be. A few minutes later, the soft knock he was dreading came at his door.
"Lucas, we need to talk." He just sat on his bed, not knowing what to do. "It's not like you can hide in there forever. We need to talk about this before mom gets home tonight, so we might as well get it over with."
When he opened the door, Lucas saw that his sisters had changed into shorts and t-shirts. He stared at Elisa's mouth for a moment, seeing that it was still glistening a bit with Emily's pussy juices.
He backed up and sat at the head of his bed, as his sisters took spots at the other end. He looked down at his knees, waiting for them to say something.
