A Sibling Secret

Kit nudged open the front door, exhausted but pleased. It had been a long day, and after all the stores and appointments she looked forward to just relaxing the rest of the evening. Laden with shopping bags she bumped the door quietly shut with her back, not wanting to wake the rest of her family. Sneaking in late at night wasn't a problem for Kit -- she'd done it many times before, and with more incriminating companions than cans of soup. She didn't make a sound as she laid down the groceries and tip-toed into the livingroom.

Thomas was waiting for her. Well, to a degree. The now post-graduate highschooler was passed out on the couch, his scrawny limbs dimly lit by the flickering of the tv's static. Kit covered her laugh. Her younger brother was so worried about her, about the doctor's visit today, that he'd tried his best to stay up despite himself.

"He never was an all-nighter kind of guy..." she hummed to herself, sneaking up beside him. His sandy-brown hair matched her own, though hers went halfway down her back. People often said they could tell immediately they were brother and sister, and it really showed. It might make things a bit difficult after graduation, considering what Kit learned today. But for right now he slept, attentively awaiting his dear sister's return in his dreams.

Kit carefully slid onto the couch and slipped the remote from his loose hand. The static flickered off, and everything quieted again. The place was just like it was a few months ago when she had snuck her boyfriend into the house while their parents were gone. Just two young bodies pressed close on the black cushioned couch, overlooked by the upstairs ledge and stairs. All alone. Thomas yawned and stretched, brushing his hand along his sister. His fingers stopped just above her lap, and it sent a chill up Kit's spine -- a light touch, just like the night they found out how they really felt about one another.

Things turned out differently than she had planned for sure, but as for how it turned out...

Four Months Ago

The front door swung open as the two college students stumbled inside, too busy kissing to be subtle. Kit and her boyfriend Allan had been going steady for a few months, and things were just really starting to heat up. At college they'd gone at it a few times already, but being back home made such naughty excursions almost impossible.

Not today though. Kit's parents were off on a business trip and only her little brother Thomas remained home. Tonight he'd be studying for his finals, which Kit knew meant he'd be out like a light by midnight. And that meant she and Allan could have fun however they pleased.

And pleased they did. Allan's tongue danced with hers as Kit pulled him backwards towards the couch. Her giggles muffled against his lips when his petting hands seized her behind. They omphed onto the couch, falling back with Allan pinning his wriggling girlfriend to the black leather. Kit kicked over a nightstand, but she couldn't care. Their stealth couldn't hide the brief escapes of their laughs, hums, then groans as they tore off the other's clothes. He peeled her cotton shirt off, she loosened his tight jeans, and soon enough their clothes mingled together on the floor Allan's rubbed his tented boxers against Kit's silky panties, already wet with waiting.

"Mmm, god Allan," Kit whispered when she could catch a breath, "I've missed this so much..." She nuzzled her hips towards him while stroking his naked flanks.

"Oh yeah, I can tell," He replied, nipping her neck, "Think you'll scream for me tonight, Kit?"

"Mmm-mmm," Kit shook her head, "My brother is still here. We can't be too loud, remember?"

"What? I thought you said you had this place to yourself tonight."

"I do, I do. It's just my parents that are gone though. Thomas should be asleep now. He's been -- mmm -- studying for tests," Kit arched up to meet her boyfriend's hand, the one that slipped up under her bra and shucked it from her tits. "But we've got to be quiet, okay? Oh just like that Allan..."

"You say that, but you're the one moaning so loud," the boy smirked and kept teasing Kit's little nipple, tugging on the small pink nub just like he knew she couldn't resist. "Maybe we'll give a show for your little bro, hmmm? Show him what a horny slut his sister really is."

"Allan!" Kit hissed through her teeth, "Don't say that!"

"Say what? That your brother would love to get a piece of his horny big sister?" Allan laughed. Kit scowled.

"I love Thomas, but not like that. Don't say things like that! Just... ooh, just fuck me Allan!"

"Shhh, we don't want to wake up your little bro now, right? He'll have to miss out while I fuck his big sister..." Allan slid Kit's panties down to mid-thigh, not bothering to take them off her before the familiar crunch and crinkling of the condom wrapper filled the silence. Foreplay never was something Allan wasted time with.

"He's not little. He's graduating in just a month..." Kit mumbled to herself, laying under her occupied boyfriend. It wasn't worth getting into an argument over, despite the instinctive desire to do just that. Thomas was a good guy, sometimes too good. She had to defend him in elementary and middle school from his tormenters who always called him 'Kit's Cat' and 'Tom Thumb' for being small. But in high school he outgrew those names and even his big sister, and she wasn't short by a long shot. But he always had called her 'Big Sis', and he still did...

"Ahhh, there," Allan said finally, stroking his wrapped-up cock a few times before recalling Kit her from her memories. "Yeahhh, time to show you what your brother only wishes he could do." The dark room hid Kit's frown, but it melted away when Allan's hot member slid between her folds.

"Ohh god..." Kit moaned as quietly as she could, "Please... please go slow. I don't want to wake-" Allan cut her off by driving hard into her. Kit hardly bit back her yelp as his condom-smoothed cock jammed inside her. His cotton boxers chaffed against her sensitive mound, and his loud grunting both enraged and aroused her.

"Q-quiet! Oh, ooh, oh!" The couch's leather squeaked as Allan's force nudged her forward bit by bit. Kit grit her teeth, trying to keep quiet and to bite back the pain of his rough pounding, but her moaning still slipped past her lips. "If Thomas is awake..." She thought, "He'll know what's happening down here for sure."

"Like that, huh?" Allan growled, ramming harder into the squirming girl.

"Ummm, oooh, not -- not so hard Allan." Kit looked up at his hard face, wondering if he could see her bitten lip and clenching eyes. Probably he couldn't, but still she gently tried to push his hips back.

"Ugh, fine -- you do it then." Allan pulled out completely and flopped onto his back. Kit blinked and propped herself up on her elbows after an awkward moment. She eyed her boyfriend's cock. Even wrapped in the condom it made her mouth water, and her friends agreed she was lucky to have such a well-endowed guy all to herself.

"Well?" Allan huffed, "Come on -- ride me like a good cowgirl." She wondered if she really was that lucky...

"Let me just cover up first..."

"Why?"

"What if Thomas sees?"

"Then he'll know his sister has bangin' tits."

"I've got to be careful in case he wakes up," she reached for her bra, but Allan grabbed her wrist and held her down.

"Nu-uh. I want to see these bouncing just for me, babe." His other hand fondled her bare breasts. She knew he loved them -- he said they were her best features. He palmed her firm tits, letting them overflow around his fingers, as if weighing and appraising them just as he had done every time her shirt came off. Kit wasn't so sure, but the look on Allan's face told her she didn't have much of a choice in the matter.

So she slipped off her panties entirely and inched forward to straddle his hips. Grabbing the base of his cock, she guided it into her waiting pussy. She tossed her head back and groaned as she slowly sunk down till his balls nudged her bare ass.

"Yeahhh, that's good..." Allan groaned, petting his girlfriend's ample hips, "Now show me why you're my bitch, Kit."

Cautiously, Kit began to post up and down. Lifting her ass and sinking back down made her pussy tighten and quiver so much better than Allan's ramming. But instead of focusing on the pleasure, she glanced at the upstairs banister. It was too dark to see much, but Thomas's room was the first door on the left. Door closed and light off, but still Kit worried. Every downward slide shook her breasts, a sheen sweat gleaming from them in the dim moonlight. Normally she'd never take such a risk, but she had been without Allan for so long, and she always got so horny around this time of the month. She didn't want sex - she needed it.

"Mmmmm, finally getting into it are you?" Kit leaned forward just so, gripping his hard chest and letting her hips work his cock. She didn't answer -- just thrust her chest out over her boyfriend's face and tantalized him with those low-hanging fruits, yearning to be picked.

He didn't pick at all though. Rather he just reclined his head against his folded arms as she pumped faster and faster on him. Finally the girl felt the beginnings of that familiar knot tightening deep inside her stomach.

"Ahhh yesss," She hissed, tossing her long hair and arching up against him. Her whole body tensed, readying for what she'd been craving for weeks. She was almost there. Allan got there first.

"Oh shit babe, I'm gonna cum!"

"No no, wait!" Kit pled, forcing her hips to slow. But he grabbed her hips and slammed her down. Despite her desperate squirming or perhaps because of it, he pulsed and shot into the thick rubber sheath.

"Nooo..." Kit mewled, grinding her hips on her boyfriend futilely, trying to bring herself off. But he grasped her hips tight, cock still twitching and pumping uselessly inside her. The tightening knot in her belly loosened, and soon all that was left was Kit's panting and Allan's satisfied groan.

"Oh yeah, that was good baby," Allan sighed, giving her a little thrust from below. The condom caught all, but even the warmth of his load radiating from it didn't do anything for Kit's desperation.

"I was so close..." Kit moaned. She grated on him, milking his softening cock inside her tight pussy, struggling to revive Allan's shrinking member. Lifting her he grabbed the base of his cock and slipped the condom off.

"What's that look for?" He said when he finally stopped groaning and opened his eyes, "I thought you were cumming with me, fucking and groaning on me like that."

"Weren't you listening to me? I told you to stop but you came anyway!" Kit leered down at him with clenched fists.

"When you grind on my dick like that, you know I can't stop. Don't blame me." Allan casually rolled Kit onto the couch and started pulling his boxers back on.

"YOU pulled me down!" Kit hissed through her teeth, "I tried to stop, but you wouldn't let me!"

"God damn it Kit! I don't get what your problem is. You were horny, we fucked, and now you're mad? What the fuck did I do!?"

"You-! Whatever. I don't want to do this here." Kit covered herself up with her arms while she groped for her clothes. Allan was already dressed by the time she abandoned the search and stood up.

"Where are you going?" Allan asked.

"To my room. Probably to get off like you just did."

"Fine then, I'm not fucking dealing with this again." Allan threw on his coat and tromped out, leaving the front door wide open in the cold night air. Kit charged the door, raging as his engine roared to life.

"You forgot your condom, asshole!" She reeled back and threw the spent condom at his smug face behind the wheel. But her gooey missile missed entirely, arching over the car and flying into the black unknown. She had imagined it splattering like a water balloon all over his windshield, but at least it wasn't around to remind her of the selfish dick who made it.

It was only after the headlights disappeared around the corner when Kit realized she was standing naked on her porch, yelling and throwing condoms into the night. She couldn't have run faster the way she backpedaled then, face getting even hotter as the rest of shivered from the cold. She breathed hard, fisting away salty tears and gulping back the sobs when she heard a shuffling.

Kit froze, then whipped around and crept back into the livingroom. She arrived just in time to see Thomas's door close nearly shut.

"Did he see that? Did he see me? Oh god! How much did he see!?" Panicked, Kit crawled to her panties and bra and threw them on before sneaking upstairs. How much had her brother seen? She couldn't know. Maybe he woke up just at the end and didn't see anything? Kit tried to convince herself that was it, but her heart seized when she heard her name through his door. Hardly breathing or moving, she knelt down and peeked into his room.

Thomas's dim bedside lamp illuminated the room as well as his occupied bed. He certainly hadn't been studying. Pictures scattered over the sheets, some spilling onto the floor, and many more cluttered in a nearby shoebox. He lay amid them, back turned to the door, moving just so slightly under his sheets. He was definitely awake though, and Kit leaned in to hear him whispering.

"You deserve better than that, Kitty."

Kit recoiled and tensed to leap back. But he didn't turn. Instead he continued muttering, "You always bring back guys like that. Why? Why do you always sell yourself short? God damn it sis..." He rolled onto his back, and Kit glimpsed the picture in his hands. It was her.

It hit her. Kit took a closer look into his room and found herself in every photo lying around. Some were normal, her smiling with friends or posing for the camera. But the most worn of them were different: One taken at the beech a few years ago when she got a new string bikini. Another when she dressed up for Halloween as a pirate wench, skimpiness flaunted. And then there was one of her just coming out of the shower, towel just barely covering her still-dripping body. That last one could only have been taken from Thomas's doorway.

Kit's heart started pounding. "Why... why does he have all these...?" The more she looked the more secretly-taken pictures she discovered. Many of them showed off her casual dress in the house, the big t-shirts hardly covering her panties and the sports bras with workout shorts. Thomas had been taking them all these years, she realized -- he always carried his camera around and developed lots of great pictures, but he never mentioned the ones now strewn about his room.

"Kitty..." Thomas sighed, commanding Kit's eyes back to her brother. He had called her Kitty since he was little, and he was the only one that Kit allowed to do that. He engrossed himself in a particularly worn picture in his one hand, but where his other one was Kit couldn't see. That is, until he pulled back the sheet.

"Mmmm," Kit's brother groaned, stroking his cock to his big sister's picture. Kit's mouth fell open -- Thomas thought that way about her!? Thankfully her voice froze along with the rest of her, so Thomas kept stroking his hardening cock and staring at Kit's picture. "I'd be so much better to you, sis..." he murmured, his precum shimmering and dripping down his knuckles. He had been masturbating for awhile.

"That fucker!" Kit screamed in her mind, "How can he say that!?" Kit had half a mind to bash open the door and beat his senses back into him, but she couldn't. She couldn't move from the spot, or even close her gaping mouth. Her eyes trained on her little brother, particularly on his far-from-little cock as he coaxed it to life.

"What a fucker!" Thomas growled, fist gripping around his shaft, "He didn't even care about her. Didn't even try to feel up Kitty's thighs... her pussy..." His pumping milked another bead of precum from his engorged member. Kit watched transfixed as it spilled down his shaft. "I bet he never even ate her out... none of them did. Sis would taste so... sweet..."

This wasn't real. Kit rooted to the spot, listening to her little brother say such dirty things about her. Things he shouldn't have known. It was true none of her boyfriends ever offered to go down on her, and she honestly thought she didn't want them to. But when Thomas said it like he did, with that lusty growl in his voice, anger flared up in Kit's chest at all her ex's for never trying. But her brother... He wanted to. He wanted to taste his big sister.

"God Kitty," Thomas breathed. His pumping sped up. "That asshole was right -- I would fuck you. Better than him, better than -- ugh! -- all of them!" Kit's head spun. He really had seen the whole thing. Seen her with Allan, seen him take her, seen his sister riding him. That was why he did this now, Kit realized. He wanted his sister. He wanted to fuck her.

Kit found her hand in her panties before she knew what she was doing. Allan left her hot, but Thomas was making her boil over. A part of her demanded she stop. She knew how wrong it was to get turned on by her own brother, but she couldn't help herself! Her panties were soaked -- Allan didn't even have that effect on her when he was fucking her. But her little brother did, just with his words. And his cock. She'd seen bigger and smaller before, but none in her eyes were as mesmerizing as Thomas's cock while his hand polished over it.

"God bro..." she breathed hotly, wondering what it would be like...

Thomas seized up and whipped towards the now wide-open door, "Wha - S-Sis!?" His eyed fixed on Kit's, and time stopped. Kit's hand ceased burying itself in her panties, and Thomas's hand petrified around his twitching cock. Neither moved, as if the scene would go unseen by them both.

Finally Thomas took the initiative, "Kitty! What the hell -- what are you doing there!?" He threw his sheets on, as if he could still hide the fact that he was wanking to his sister. It didn't help that he dropped the photo he was staring at onto his lap. Kit stood up and recovered her hand from her moist panties.

"Um..." she said, "I heard something, so I came to... came to..." She shook her head to stop herself from staring at his cock tenting the sheets. Regaining her composure her hot flush of anger revived all at once. "I mean, what do you mean 'What the hell'? What the hell is all this!?" She threw her arms out over the picture-strewn room. Thomas shoved what he could back into the box, but the damage was already done.

"I -- I uh, I was-" he stammered, shoveling pictures wildly. Kitty stomped forward.

"They're all of me, huh!? God damn it Thomas! When did you take all these?"

"Here and there... I guess... Hey!" Kit snatched up the one he was staring at so intently before he could stop her, determined to see just what a pervert her brother really was.

It showed her laying passed out on the couch downstairs, her shirt bunched up under her breasts and shorts crumpled from a night of partying. Her hair splayed out every way underneath her, and she was fast asleep. That was all -- it wasn't even revealing beyond that, and its focus was on her peaceful face, a little smile crossing her slightly-open mouth.

She remembered that night in bits and snatches. When she was a senior in highschool she snuck home after getting really hammered, and must have crashed on the couch. When she awoke the next morning, she found herself covered up in one of her soft blankets. She thought it was her parents who did that, until they found her and naturally chewed her out for being so irresponsible. All these years she believed she simply forgot wrapping herself up that night, but the blanket wasn't anywhere near her in the picture.
