At long last, Laura felt the powerful waves of orgasm wash over her as her own fingers slid in and out of herself, desperately trying to hang onto the pleasure going through her head like a drug. Unfortunately, she eventually crashed back down to reality, and found herself lying sticky and spent, naked from the waist down, on her bed.

Laura pulled her two fingers out of her cunt, staring at the pussy juice covering them dispassionately. She needed to wash them off, she thought idly.

She was sixteen years old, and perpetually sexually frustrated. If you were to ask Laura about Laura, she would tell you that she was too fat, and pimply, and that she needed a haircut. Others would definitely agree that she had shoulder-length black hair, small brown eyes, and freckled skin. Some would even add that she had a pretty, soft face and perfectly-sized breasts.

Pulling on her panties and shorts again, Laura left her room and walked over to the bathroom, wondering if anyone could tell what she had just did. If she smelt of it, she would have to take a shower as well.

Laura reached the upstairs bathroom, which was spacious and carefully decorated (her mom was enough of a nutcase to try and make the bathroom look good.) She turned on the faucet and slowly rinsed her hands under it, then added soap.

"Why are you washing your hands?" Mark asked from the door frame. Mark was Laura's younger brother, by two years, and a constant thorn in her side. He had this constantly arrogant look on his face, and spiked hair that everyone but Laura seemed to find cool.

She cursed. She had deliberately chosen a time when their parents were out of the house (they always seemed to be out of the house, on a date or shopping or wherever) to masturbate, so that no one would discover her. Laura had known Mark would be in the house, but assumed that he'd be glued to that new X-Box game he had just got for days on end, much less another half hour. At least he had arrived after the deed was done

"Um, personal hygiene?" Laura answered with a role of her eyes.

"Oh, give me a break," Mark shot back. "You never wash your hands. You're a complete slob. Dad keeps criticizing you about it, remember?"

"Hey, shut up." She swung her wet hands at Mark, which he evaded tauntingly, but still got hit in the eye with drops of water.

Mark grabbed a nearby towel and whipped at her playfully with it. "So, by the way, who's Chris?"

Laura froze. "Who?" Chris was a cute guy in her class whom she fantasized over repeatedly... including just a couple minutes ago.

"Well, you kept saying his name when you were jacking off back there... like 'ooh, Chris, please screw me now' or something..." Mark kept on grinning despite Laura's growing look of horror. "Wait, would that be 'jilling off' cause you're a girl?"

"You asshole!" Laura cried, before just about full-on tackling him. He laughed as he squirmed under her, tickling her belly playfully. She couldn't resist giggling, and rolled off of him, still shooting him glares of death-- but not as serious death.

And then, somehow, she found herself on her back, Mark underneath her, with his hand down her shorts.

"What the hell, you pervert..." she muttered, but found her body strangely paralysed as she thought she should get up.

"Wow, it is wet down here," Mark commented snidely as he cupped her mound. An obscene jolt wen through Laura's body.

"Mark, stop it," she said, trying to be firm, despite her voice's shaky foundation.

Mark slid his fingers out of her and outside of her jeans. His sister's juices were visible on his fingers. "All right, all right. Just get off of me."

Laura tried to work up the energy to move, but for some reason found she couldn't. It was like her legs were cut off. Despite a hard point pressing against her ass, which she really didn't want to think about, she couldn't make herself get up.

With a shove, Mark sent her tumbling forward, and he got up and brushed himself up. He grinned mischievously. "What happened? Were you enjoying yourself that much?"

"Sh-shut up," Laura snapped, bringing herself to shaky feet. She wondered what had got into her.

"How do you do it, by the way?"

"Do what?"

"You know... masturbate. While we're on the subject and all."

Laura flushed red with anger and embarrassment. "Since you're so fucking curious, why don't I show you?" she hissed. Not really thinking, she marched past him into the open door of her bedroom and yanked down her pants.

Mark followed her dumbly, as she now seemed to be the one surprising her sibling with sexuality. Still, he let a disbelieving grin cross his face.

Even though she had just done it, Laura found a sudden reserve of pent-up sexual energy and frustration that motivated her to frig herself again. Besides, she thought as she slid a finger into her slit testily, it was certainly wet enough now. "See, it more or less involves me sliding my fingers into my pussy here until I come." She didn't usually use such harsh words, but Laura was in a weird mood right now-- half angry, half excited, and definitely passionate.

"Wait, girls come?"

Laura raised her left hand and smacked herself in the forehead with it mockingly. Her right hand was still occupied at her crotch, where her thumb was gently massaging her clit and a second finger was sliding in and out of her slick passage. "Doy. Of course. No wonder you're a virgin."

"Hey, who says I'm a virgin?"

"Are you saying you aren't?"

"No." That still didn't tell her much, as admitting a sexual liaison would be more hazardous than admitting inexperience.

Laura was now thrusting her fingers in and out of her dripping pussy at a pace that surprised herself. Normally it took her at least ten minutes to get up to that speed. She didn't know why, but this stupid small talk with her brother was getting her hotter than her dirtiest fantasies of Chris. With a shrug, she slid closer to him.

"Come here, Mark. Since some poor soul's probably going to end up sleeping with you eventually, I'm going to teach you how to please a woman." Mark was unsure, but his sister's wanton display-- her long, creamy legs, spread out as her fingers energetically dove into her slit, her juices flowing into her garden of black curls-- had made him horny as hell, and at this point he would have done anything that vaguely sounded like sex.

She tossed aside her top, and as Mark had since realized from her nipples sticking out like eraser nubs for the past several minutes, she wasn't wearing a bra underneath. He gawked at his completely naked sister, her firm breasts hanging in the sunlight filtering in from the window, almost invitingly.
