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.
