Sarah's shota corruption

Matthew's parents were away on a business trip for a couple of weeks, so of course his girlfriend had jumped at the chance to come over for the afternoon to hang out. Sarah hadn't seen Matthew in a while, what with all of the work that accounting was piling onto the interns. So naturally, she was glad to have a treat to herself.

She climbed the concrete staircase leading up to Matthew's place, already expecting him to be running a bit late from the way he responded to her text when she asked how far out he was. Arriving, she leaned back against the balcony to give him a few minutes to get here. After waiting around a bit longer, he still didn't turn up, so Sarah decided it couldn't hurt to get comfortable, sitting down to wait a bit longer.

She opened a casual game on her phone as she heard someone climbing the staircase. That wasn't Matthew; this kid had quite careless footsteps. Just as Sarah looked up, a young boy walked through the hall, evidently arriving from school, wearing an oversized jacket, and yet managing to make it tight around the neck.

"Oh, you must be Sarah," he remarked casually, continuing to the door next to where she sat.

"How do you know about me?" She stood, folding her arms expectantly.

He gestured toward his ears, "My brother never shuts up about you. Makes my ear bleed from time to time." The boy shrugged.

"Oh... right, you're his-"

"Brother," the kid interrupted with an obvious expression, not even bothering to look at her, as he pulled his key ring out of his pocket and worked the lock open.

His height didn't even hit Sarah's chin, he looked like any other kid that age - until she looked over his frame beneath his loose-fitting jacket. Sarah was only expecting Matthew's brother to be in a scrawny, prepubescent form. But as the door opened and the young man's jacket swayed freely, there were indications that something was different.

Sarah chuckled and took another look at the kid, giving him a once-over. It seemed his hair and wardrobe were as careless as his walk. The jacket, quite larger than would suit a preteen, from how baggy it was around the waist, was tightened snugly around the shoulders, showing an abnormal width to them. As her eyes travelled further, Sarah's gaze rested on the apparent bulges of pecs showing through the loose neckline, as though his growing chest had brought him discomfort with the collar. Sarah's face grew a noticeable shade of red; was it wrong for her to stare at a child like this? Her boyfriend's little brother, nonetheless?

She tried to ignore how long she'd lingered on his chest and just focused on his overall form, but the image of how big and well-shaped those were just burned in her memory. Was she just pent up? it'd been a while since she'd slept with Matthew, too, what with how busy he was, lately. How old was he anyway? She had no clue, but his face made it clear he couldn't be older than his early teens.

"Are you coming in?"

"Sorry, I was just..." she stammered, quickly turning away before he caught her red handed. "Stuff from work," she gave him one last awkward laugh before deciding it would be best for her to wait inside. Hopefully it wasn't obvious...

But of course, the boy had picked up on the glance that she gave him. As they passed into the apartment, a slight grin passed his lips and he gave a little chuckle. With his recent developments, this child should have expected his older brother's hot girlfriend would actually be perving over him.

"It's Chase," he turned, closing the door behind the two, "if you want some water, the kitchen's to the left."

"Thanks, uh, is Matthew still running late? I'll just hang out." Sarah, doing her best to seem inconspicuous and not a perv checking out kids, took a quick glance around the home. Chase led the two into the kitchen and she plunked herself onto a stool to watch the boy drink out of a mug.

"Said he's still an hour away," the young boy reached over, "you know how bad traffic gets. If you need me, I'll be breaking some sweat," he said, finishing his drink. "Workouts usually take me an hour, feel free to, well," Chase took his jacket off as he moved towards a decently equipped home gym, now in nothing but an overly tight-looking undershirt, leaving it wide open for Sarah. He waited for her eyes to follow his muscled pecs and neck, "look around." He added with a slight giggle.

Was his kid brother flirting with her? "How old are you anyway? Don't you have homework or something?"

"Eleven," he tossed his jacket aside, leaving the door open, "and no, it's a pretty light load today, already done almost."

Sarah's body was tingling with arousal, knowing that she should get the fuck out of there. This wasn't right. It had just been too damn long since Matthew had treated her right; it was driving her nuts and making her have weird ideas. This boy couldn't possibly be fucking serious... "...uhh, wow, that's impressive," Sarah replied, unable to pull her gaze away from his massive upper body.

"This? Of course..." Chase grinned to himself, knowing full well the effect he was having on Sarah. With the vast amount of extra room that his growing frame was taking up, this preteen was filled to the brim, stuffed full, with mouth-watering beefiness. His smooth shoulders already strained and thickened, filling and flattening to accommodate a rapidly bulging pair of masculine traps.

Chase walked to the bench and lay down on his back, taking the bar, pressing it above his head to test out the weight on the machine. "Too light? What's this..." He groaned, propping the bar up, and then sitting up. "I guess Matt's been doing the same sets this morning," he huffed and laughed a little.

The eleven year old hopped up from the bench, walked to the some discs in the corner, and loaded more weight onto both ends. "The truth is, this shit is getting pretty easy for me," he boasted, heading back to the bench, "can you believe he's even struggling with my warm up weights? Guess I'm growing a lot more than he can." He was flexing his torso knowingly, pushing his chest out and shoving his shoulders back.

"He certainly is..." Sarah's eyes widened. Eleven years old, and already a stronger man than his own older brother? Her skin began to warm under her clothing from Chase's impulsive flexing. He looked so smug, acting as though it was normal that a grade schooler could lift so much. "I'll let you get back to work, then."

Sarah made an excuse about needing the washroom, and scampered to the nearest toilet. In the cramped, closed space, she closed the toilet lid and seated herself, facing the seat to prop her feet on and start stripping. Her jeans slipped down past her legs and gathered in her hands, which she then folded up and dropped on the floor.

While her brain was conflicted and shouting at her to put it all back on, her loins were gushing from the little display outside. Sarah leaned back, pushing her back onto the door. One hand supported the inside of her knee, while the other slipped its digits past the damp fabric between her thighs, stroking a single finger back and forth over the parted lips, taking a moment to tease the hardened clit.

Fuck! Her brain demanded, imagining Chase standing before her, the clothes torn off his sculpted torso, holding that cocky grin while he strutted his beefy frame up and down. No, wait, no that didn't seem right. Why did her body want a man of that size? Why would he be so tempting for an adult woman, such as herself, when the appeal of boys his own age didn't even exist for her?

What is happening to her...? She pleaded to the blank ceiling. "Uuuungh..!!" A jolt went through her, causing her legs to cramp up, as her cunt shuddered. Her fingers still rubbing circles along the button, she moaned out her first orgasm, shaking as she struggled to muffle the noises escaping her mouth, trying not to alert the child out in the open.

Was the scent of her body pouring into the air? Her flushed red cheek, straining to keep in her moans as she came to the thought of a man much too young to even date, was not helped by the heat building in her abdomen. The man in her fantasy was, in fact, a primary school student and a pervert was jerking off inside the apartment he and his brother shared.

She came again. Sarah panted, forcing her body to stop and calm down. It felt shameful how fast she'd come just to the thought of some dumb brat who just so happened to have been packing an astoundingly powerful physique for a kid his age. She rested against the cool surface behind her, as though hoping it might sweep away the shame of how wet a literal child's innocent arrogance made her.

Her thoughts wandered back to Chase: his heavy and deep-chested form, and just how much beefier his silhouette was compared to any grown man's. He was the very kind of body she'd been starving for: one that was perfectly stuffed, bulked out, and swollen, leaving little space in his outfit as his figure continued to pump. She could imagine his powerful limbs bulking into thick, ropy masses of muscle, expanding out and towering above, built for destruction. She imagined him being twice the man her boyfriend ever was, not a big stretch.

Arousal stirred deep within her and she cursed. That little bastard was way too young. Why, when any good sense reminded her of that, was he occupying her thoughts in the worst ways. Shit, this was wrong, but her loins couldn't agree on this. Sarah was utterly embarrassed to be reduced to fantasizing a grown man's muscular body onto an eleven year old kid, and was upset at herself for feeling this way about a fucking child.

Though she couldn't get it to change, the hard facts hadn't left her: in the eyes of the world, he would remain an underaged kid to her, no matter how big and adult his body was becoming. His oversized limbs, which would put his brothers' arms and chest to shame, looked cute, so much that it infuriated her. In reality, he was barely a bit tall for his age, but was occupying half the room in her mind. It wasn't fair, especially as every time Sarah wanted to remind herself of this, all the sights and images her mind conjured up were that of the massive, hulking physique attached to his childlike features, gazing at her with all the respect and subtlety of a hormonal teenager watching porn for the first time.

All the parts inside her, and the voice in her head, were all at war with the fact that he was not a real adult. Was that, however, going to stop her?
