Class continued as per usual. Miss Harper exposited on information useless to Mia, her focus skittish as it darted about the room, tracing one set of eyes to another. Dedication kept some centred on their studies, while the majority gawked in Mia's direction. Boys followed her breaths with careful precision, watching the rise and fall of her oversized chest, while girls found their fascination torn. The centaur understood why. All too well, in fact.
Her fingers threatened the pen in her hand and her teeth ground together. Though impossible, she swore people were touching her through their stares. They massaged her tits, digging their fingers into the hole to make it wider, as others coaxed her cocks from their homes. She scowled at herself and flicked her tail. The silken hairs brushed against her black, leathery scrotum.
She snapped the pen, jaw locked against her traitorous moan. Idiot, Mia berated herself. Stupid. Dumbass. Moron. She should've taken the chance when Miss Harper offered it. Escape had come within her reach, yet she let it pass her by. Any attempt to leave now would draw extra attention, some she could do without. Mia glanced to the opposite side of the room, where Bella's persistent stare remained.
How could leave with those hawk-like eyes trained on her? Worse, Bella wouldn't hesitate to follow. For what? Mia decided not to guess, afraid the answer might exacerbate her situation. Her shirt groaned, her sensitive ears alert to the noise. No one else heard it.
"Wake up," Mia moaned under her breath, head in her hands, "Please let this be a dream?" Her request fell silent, replaced by the strenuous pulling of her shirt. Its elastic material thinned against her breasts, defining her nipples with growing clarity. A girl, seated in front of her, noticed with bug-eyed awe.
Mia ignored her, but the heat in her face refused to go unnoticed. Nor the fire smouldering in her equine-half, rather, in her cocks and balls. Worse for her balls. A simple breeze equated to a firm squeeze, a brush of her tail made her think a hundred tiny fingers caressed her, and the constant bubbling sensation of her cum... what was happening to her?
Miss Harper stumbled in her speech, bringing the centaur's gaze to her flushed appearance. A moment passed before she stuttered back into her lecture, though her eyes lingered on Mia. No, the doubly endowed centaur thought and followed her instructor's gaze. Sure enough, it came to a rest on the ever-stretching hole in her shirt, through which entire inches of cleavage were visible. Each breath bared more.
Everyone's staring, Mia thought. Nothing new, from this morning to her early teens. It took years following her accident for the locals to treat her as normal, and longer still for some. No one stared as her classmates did, though. Annie and Keira drifted into her mind, their faces embroiled in lust at the sight of her hulking cock, then at her dicks. One girl licked her lips, another gulped and a third unbuttoned the top-half of her shirt.
Mia's nose twitched at a familiar odour. Strong and plentiful, dampening the atmosphere and tantalising her sinuses. She held onto the breath, let it swirl in her lungs, the aroma so strong it sat on her tongue. Tangy and sweet. Intimate yet unknown.
"Hmm," someone sighed from in front of her. She tilted her dead down and saw a girl, eyes fixed on her like the others, with her hands buried in a pair of shorts. Under the tight fabric, her actions were obvious. Knuckles raised and fell in a rhythmic pattern, their descent punctuated by a subtle moan. She lifted the waistband and revealed a series of web-like strings between the garment and her skin. The strange familial scent wafted to Mia, stronger than ever.
Another person moaned nearby. Mia didn't want to see. What good would it do? How could she, or anyone, mistake that noise? If she looked, then she'd see another girl fingering themselves. Or would it be a boy, she wondered. Would they try stroking their dicks to the sight of her, to the fact that she stood entire feet above even the tallest student... to her giant cocks, still wreathed in their fleshy prison.
She twisted her head to determine who made the noise. What did she expect to find? One of the dedicated students masturbating, someone she knew, or another random onlooker. Perhaps Annie had snuck in? There shouldn't have been any surprise for who was responsible.
Bella stared back. Skirt raised and pussy on blatant display, swollen mons and moist, puffy lips, as one hand filled her insides while its counterpart fiddled with the hooded nub. Her fake tits heaved in their constraints, ill-suited nipples poked against the fabric. She rolled her hips with her hands' motions.
"Fuck me," she mouthed. Mia drilled her stare into the near-blank pages of her notebook, lowered her head and hunched her shoulders. Sights were easy to block, so long as she concentrated, but sounds and smells portrayed another problem entirely. Her senses caught it all. Clothing rustled, people moaned, sighed or chatted about her. They clouded together, drowning out the specifics of the other.
Her nostrils flared, unbidden, and drew in waves of potent musk. Lust circulated her sinuses, turning through her head to mask her thoughts in a dank haze. Her cocks throbbed and pushed, massive heads peeking from the sheaths. Warm air caressed their bulbous tips, slipped into her wide urethras and breezed across her sensitive insides.
Two paths faced her; stay or go. One led down a messy road and the other led to safety, its meandering way riddled with possible issues in the form of a person. Mia didn't so much as glance at Belle, certain she still stared as she masturbated. Leaving would signal the deviant student to follow, intent on fulfilling whatever fantasy compelled her fingers.
How long was left? It couldn't be long, though she hadn't checked the time since before class and Mia didn't dare glance up from her desk. What awaited her, row after row of horny students, wouldn't help. At all. Did minutes remain? An hour? Seconds?
She had to leave. Soon.
Every second, as best she could estimate, made it worse. The desire. Mia's balls pulsated, ached and churned, a direct extension of her cocks. Faint tremors ran across her genitalia, from base to tip. Something hot beaded atop her pricks, rapidly cooled by the air, then slid across the broad head.
Oh fuck, oh fuck, oh fuck...
Mia forsook the risk and raised her head to the clock, positioned several feet over Miss Harper's desk. Ongoing masturbations continued in her periphery, tugging on her determination. The time, she repeated in her mind, just find the time. Her eyes fixed on the clock hands. How long...?
Miss Harper clapped her hands and broke the centaur's focus, "And that's all for today. Uh, if any of you were paying attention, reflect on what's been taught today. And Mia..."
Mia stood, abandoning her notebook for the sake of a hasty retreat, and walked from the room. Each click of her hooves resonated throughout. Her hindquarters swayed, tail swishing with nerves, as did her overstuffed sheaths, strained against their wards. The centaur ducked under the door, forcing her chest out. A loud rip drowned out the doors hissing shut. She grimaced down at her chest. A long chasm split her elastic top, now held together by her oversized teats.
She trotted into the empty hallway and down a corner. Hundreds of feet crowded her hearing, each marching toward their respective doors, owners muttering to one another. Mia's custom restroom came into sight, an unassuming swing door with a plaque of a centaur's silhouette hung on it. A single bolt locked it to the other students, placed so high that most would need a ladder. She reached it as anyone would grab their handles.
Sterile white met her gaze as she slipped inside. Under orders from her doctors, the college prioritised hygiene for her bathroom, leaving it clean of any filth she, or her friends, might introduce. She didn't care to know why they ignored the recent messes, or how much they paid the janitors to keep quiet about it. Other priorities demanded her attention. She stepped into her single mirror's sight and sighed at the fate of her shirt.
Useless, the garment soon found itself stripped from her form and crumpled on the linoleum floor. Mia frowned at her reflection, watchful for the tell-tale sign of her persistent growth, and yet nothing caught her eye. No random lurch in height, or fluctuation to her bust, muscles or arms. Was it so minute she couldn't see it? Perhaps the hints were obvious and she ignored them.
"I'm going mad," Mia muttered. Growth spurts themselves were far from uncommon, even for someone in their early twenties, yet nowhere in her life had she heard of someone growing by the second. It's impossible, she thought. Unless she recorded a video and studied it. That would work. Too bad she'd left her phone behind.
"Yo, Mia," Annie stepped inside.
"Holy shit!" The centaur whinnied, blushed and whirled on her friend, eyes wide.
"I knocked," Annie said.
