Claire was so excited to be coming home from college for the holidays three days early. She couldn't wait to surprise her family. They expected her to arrive on Monday by bus, but her roommate offered her a ride after she found out Claire's hometown was the same as her boyfriend's.
She stepped out of the car and waved goodbye to Marie with a big smile and watched her drive away. Then the 20 year old breathed the fresh air in deep and turned around, happy to see her childhood home once more. It had been a long first half of the year and she was more than ready for the break.
Figuring no one was home since it was only early Friday afternoon, she let herself in unannounced. As she set her backpack down by the coatrack in the foyer and kicked off her sandals, Claire caught a glimpse of herself in the full-length mirror her mother often used to double-check her attire before leaving for work.
'Not very stylish, but not bad either', Claire thought to herself with a giggle, checking out her reflection. She was wearing an 'ugly' Christmas sweater and sweatpants, choosing comfort for the long road trip over anything else. But at least her black-rimmed glasses were always on point.
Perhaps she'd have time to change into something better before anyone else showed up. Then again, she had gained a few extra pounds as many freshmen do and the baggy outerwear helped her self esteem, so perhaps not.
Marie had assured her that she was still attractive in a 'cute chubby' kind of way. And it was true that most of Claire's weight gain went to her butt and breasts, so much so that last week she found out her bras no longer fit, hence the sweater since she had to go without. But there was still some 'baby fat' on her tummy that made her feel uncomfortable.
The biggest boosts to her ego though were the lustful sidelong looks Marie's boyfriend Chase and Marie herself gave Claire ever since her unfortunate growth spurt. It's one reason she could keep in such high spirits now. While others in her situation may be depressed or worse, Claire was upbeat and even currently a little pleasantly warm between her legs, despite being single.
Just then, she heard some odd sounds coming from the living room down the hall. Clothes shuffling, a sigh, maybe someone sitting on the couch? But no one's home so that couldn't be right. 'Could be Buster getting into Mom's laundry basket again?', Claire thought, shaking her head with a smirk.
So, curious, she tip-toed over to the living room door and peeked in, expecting to see the family's dog amongst a bunch of clothing strewn across the floor. What she actually saw though took her breath away and shook her to her core.
There on the couch was her 18 year old brother Chris, naked with his legs spread wide and masturbating, his clothes tossed all about the room. He was stroking the biggest cock she'd ever seen outside of porn, using both hands. A solid 8 inches at least, she estimated, and thick enough that his hands couldn't close around it completely.
She honestly didn't know what to do. Her breath was gone. Her mind was blank. She couldn't stop watching even though she knew she should. Her only saving grace was that his eyes were closed. If they opened, he'd surely see the top of her head and her wide-eyed stare from behind the door, straight across the room.
And then her mind switched gears suddenly, a million thoughts flooding in, all at once. His big, meaty cock was so beautiful to her, the circumcised head dripping with precum. Was it throbbing? She couldn't tell but she thought so. His balls resting between his legs, looking full to bursting.
What she wouldn't give to be there on her knees, licking all of that, gagging on it, worshipping it. It drew her, allured her, gave her all kinds of perverted thoughts, making her weak at the knees, her pussy drooling inside her sweats. She didn't have the courage to act on any of it, of course. It was wrong, too taboo. But she needed to be touched just the same.
Her breathing ragged, desperately trying to remain quiet, Claire snuck her hands down her body, her eyes never leaving sight of Chris royally fucking himself. She tweaked both nipples through her sweater. They were hard already, and she wished in the back of her mind they could've pushed through the material so they'd be bare to the touch. Then her hands went lower.
She knew she shouldn't do this. It was so wrong. She should go grab her stuff, and go out the door, and knock. Or go hide up in her room and try to forget this ever happened. But instead, she stayed, watching, and her hands only barely pushed at the waistline of her baggy sweats, before those pants dropped to her feet. She stepped out of them and inexplicably kicked them far away, toward the front door.
Chris was moaning louder now, one hand moving from his cock to his balls, fondling them. His other hand would occasionally stop stroking his big fuck stick to slap it across his tummy, making wet smacking sounds and leaving slick trails of precum that went higher than his belly button. His spying sister idly wondered if he could fuck that hole of his. Like her, he was 'cute chubby' for a boy his age, so his bellybutton was slightly deeper. Some would say he had a 'dad bod'.
In fact, unlike his previously slimmer sister, Chris was always cute chubby. Unassuming. It's part of the reason she was caught so off guard by his huge man meat. Claire never thought of him in that way before.
Though, now she understood his never-ending line of girlfriends. They either wanted him like she now did, or each became intimidated seeing him so he'd have to find another. She could only wonder which.
Her panties were soaked through when her fingertips touched the front. She watched his thumb glide over his cock head, and her thumb did the same over her own clit. Frustrated with the thin, wet cloth in the way, and not really thinking, she tugged hard at her panties twice with both hands until they ripped loudly from her body.
She gasped at the sound, her eyes bouncing from Chris's cock to his face, praying he didn't hear her, and scolding herself for her impulsiveness. She waited for the longest few seconds of her life, but his eyes didn't open and he didn't stop. She was in the clear. She sighed thankfully. Maybe he was moaning at the time.
Claire watched her not-so-little brother jerk his cock faster from her semi-hidden spot, and her own fingers easily slipped inside her pussy and she mimicked his motions, fucking her twat just as fast, imagining fucking him. Her other hand, still holding her torn apart panties, stuffed them in her mouth to muffle her moans, and she began sucking her juice off the cloth.
Then those fingers grabbed the hem of her sweater and lifted it up over her head, dropping it behind her back. They kept lifting the sweater up and over until her head came out from under the collar, freed, leaving most of the material dangerously bunched behind her neck, her arms the only remaining connection still in the sleeves. With her heaving chest bare, and the rest of her nude from the waist down, there would be no way to quickly cover up if caught and the thought alone almost made her orgasm.
With his eyes still closed, much to Claire's relief, Chris then did something she didn't expect. First, his hand travelled up his body, from his balls, up along his lengthy cock, stopping briefly to cover his fingers in a copious amounts of precum. Then it kept going, his fingertips leaving a wet trail up his tummy to his chest, circling his left nipple.
Her free hand did the same along her own body from pussy to breast as she watched him, shivering as she covered her left nipple in her juices. She desperately wanted to suck on that big tit too, but her mind was in a state of submission to her brother's unknowing guidance so she waited.
She watched. She mentally pleaded. She fucked four of her fingers faster, her thumb over her clit in a blur, her other hand pulling on her tit so much it nearly hurt. The mild pain and incredible pleasure overwhelming. And she waited.
Then he did something she never thought she'd see. As if reading her mind, he leaned down and licked, then sucked his own nipple, his hand helping lift it. She hastily did the same, stuffing as much of her own breast in her mouth as she could, her panties still gagging her, overflowing over her tit-flesh with drool and remnants of girl cum. She delighted in the fullness she felt from both ends. Stuffed.
She came hard in that moment, pure bliss and abandon, like she'd never felt before. She wanted to wait for her brother but she couldn't. She moaned into her tit and against her panties, and bit down hard enough to make her wince, though the cloth kept her from breaking skin. The sound barely escaped, a muffled whimper.
Needing to breathe, her mouth opened wide, her breast dropping with a wet smack against her body, her tattered underwear flittering gently to the ground. Her free hand reached behind her to the waist high cabinet along the wall for support. She caught her breath for a moment before realizing in the commotion she lost sight of her hunky brother, having closed her eyes in the heat of passion.
She looked his way again. His eyes were open! Fortunately for her though, he was looking out the big bay window and seemed to somehow still be unaware of her lusty presence. Maybe because she had backed slightly away from the doorway, to be against the cabinet. She sighed in relief, thanking her lucky stars that she still saw spinning around her.
