She had fucked it up. Mia trotted through her home, ducking to avoid the 'low' doorways, and settled before her tv. She couldn't settle on anything and left it on a random documentary, though her mind stamped any information out, too caught in what had transpired with Rhona. No one had denied her like that, or at all, since this ridiculous growth spurt started.
Even now, her shirt tightened against her chest. If she looked down too long, she could see the slight wrinkles straighten and the design distort around her breasts. The neckline dipped as if pulled by weights to reveal more of her cleavage. Mia removed it with a huff and stared at her bra destroying mounds. Nothing in the stores fit. They were barely enough to reach her areolae before the straps' elasticity gave out.
Those concerns could wait. What she needed to focus on why she behaved as she did. Any number of possibilities arose, each plausible and deniable in equal measures. Hormones were the likely culprit, given what her body had become. That's right. It wasn't her fault, but her body's. If she hadn't become a stupid experiment, if that crash hadn't happened, then none of this would be a problem.
She'd be a normal girl. A gymnast if all went as planned, maybe on her way to the Olympics. Her coach had claimed she was a prodigy after all, and she practiced longer and harder than anyone she knew. Except Keira. It was a miracle that she slept with how often she worked out.
Mia folded her legs and leaned against her horse half. The fur was soft under her fingers, but layers of muscle, thicker than any she'd touched before, ran beneath it. This was a horse's body after all, a stallion's at that, of course it would be stacked with power. At her size, she could outrun any prized racehorse. Oh, that sounded great. To feel the wind in her hair, rippling her fur, carrying her tail and breaking against her sheaths would calm her.
"It's not that late yet," Mia murmured and climbed to her hooves. She went to grab her shirt, but left it, "Not like anyone will mind." Her closest neighbours were a mile away. She stepped from her home and into the fresh air. A few circuits around the land, then she would get some food. The pantry and fridge should be stocked, since the suits who catered for her hadn't messed up from day one.
She went to the border of trees around her land. The leaves tickled at her fur. A breeze stiffened her nipples in the cooling weather, while her eyes drank in the orange splendour of the sunset. Her house cast a stretched shadow to her. That would be her marker.
Mia broke into a gentle gait. Without another person on her back, she could focus on her muscles and let them move as they wished. They pushed against her hide, lifting and falling to a building rhythm. Each cycle swung her balls, which made her sheaths bounce in place, while her breasts followed their lead. As she built to a gallop, the air turned to a whistling gale as it broke before her.
Sky and tress blurred together. She upped the tempo. Her hooves thundered into the ground, leaving dense imprints for her to follow. The air chilled further against her skin as sweat snuck to the surface. Stray drops were flung from her bounding chest, which clapped off-beat to her hooves. Each slap of moistening flesh tempted her thoughts, luring them to other pleasures.
Tendrils of air glided past her sheaths. They snuck teasing licks at the peaks of her cocks, ushering them further into the wind, while her balls became matted in sweat. It was almost uncomfortable to have such a strong current against her pricks. She knew someone who could solve that. Several people in fact. Any would be glad to be strapped to her belly, while their own bulged with seed and cock, all while she rejoiced in her freedom. It would heaven.
She could have someone to each cock. They'd make out while she ran and fucked them, rubbing their sweaty forms against her underbelly, marking her in their scent and vice versa. But, unlike theirs, her odour wouldn't fade. They could shower, use whatever lotion they wanted, but they'd still wake and smell of her. And they'd want more. Any one of her friends would line up again to be drenched in dick sweat and filled with cum.
Mia panted as she came to a stop. She needed to cum. She twisted her body around and saw her erections, each throbbing visibly, lusting for a pussy or ass or mouth, or any combination of the three, to be stuffed into. The day had passed, however. She couldn't call her friends at such a time. Annie needed to study, Keira would be working out and Rhona... probably wanted nothing to do with her.
She supposed Roshni was an option. As was Diana. But they were off hours. What reason did they either have for coming to her? Sex was a good one, though she didn't want to impose. A blatant lie. Every neuron in her body flared in need. A need that couldn't be satiated without someone's help.
Dejected, Mia returned to the house. Her cocks bobbed and slapped into her stomach, each connection was a glimpse of pleasure, though not enough to get her off. Perhaps she could talk Roshni into getting a 'relief worker' stationed at her home? She doubted Annie would mind. It bordered on a medical need. Given what she could ejaculate already, she dreaded to think what might happen if she stored up for days on end.
The house seemed smaller than when she left it. Which should be impossible. She couldn't be growing that fast, but she wasn't so sure. Her shirts in in the past week had grown tighter as the days wore on, and it would explain why her libido wouldn't shut up if her hormones were so active. That being the case, what was the point in buying clothes? She should just buy a poncho and leave it at that. It'd make touching herself easier.
"Jesus, what's wrong with me?" Mia sighed. She leaned against a wall, keeping her weight off her dual erections. Just the slightest pressure and pre-cum oozed out. Sweat dried on her skin, leaving a dense, musky odour in the air, but a shower seemed too much effort. She yawned and shuffled to her bed, careful of her shafts, and settled in. It was early, but she would rather sleep than suffer her arousal.
Sadly, sleep can be brittle, shattered by some random noise or an overbearing thought. Mia jerked back to consciousness, groggy and annoyed. Darkness recessed in the window, her tv the only source of light. She rubbed the sand from her eyes and stifled a yawn. Well, she was awake, so she should at least get a drink.
"Oh, great," Mia said. Her cocks were still hard. They seemed almost angry at her for leaving them. Her dreams must've fuelled them too. She had faint recollections of Annie and Roshni's tiny bodies grinding against her massive one, teasing her until her balls were bigger than them. Why couldn't it have been a wet dream?
"Shit!" Mia yelped when her head hit the ceiling. She'd grown in her sleep. Of course. Now she couldn't stand upright in certain parts. Hadn't they said the ceiling was raised for her? Most were about eleven feet high, hers was closer to thirteen. If her growth didn't stop soon she'd need a new place to live. Like a stable.
Some parts were taller than others to her fortune. She moved to the kitchen and stretched, sighing at the satisfying crack of her joints, and the heavy jiggling to her bosom. As she looked to them, taking in their new size - which dwarfed her head, which likely shamed basketballs - her gaze glimpsed a black, flat shape. Mia shoved her glorious melons apart and saw a welcome, if shocking sight; her cocks had reached her front legs.
"Wait, then that makes them, um... a horse is about as long as a person is tall I think, so... Holy shit," Mia twisted her human half to see how her equine form stretched from view. Her tail swished to and fro, tickling her enlarged testes. She gulped. If she was hitting her head, then she was about thirteen feet tall, therefore her body was about as long. Mia grabbed a pitcher, filled it with water, and glugged it down.
"Okay," she said after a deep breath. Her stomach rumbled in response. She'd forgotten to make something before falling asleep, "Got it. Guess I'll just make pasta or something."
Fifteen minutes later, she held a plate stacked high with penne and a tinned sauce. Another, identical plate rested on her table, waiting for its turn as she inhaled her meal. A third, emptied dish rested beside it. She'd put on a random sitcom in the meantime. Wasn't bad, not hilarious but amusing enough.
As she finished the third plate, someone knocked on her door. Good timing, she thought and carried her dishes back to the kitchen, her stomachs full and relaxed. Like other impossibilities, her horse stomach had acclimated to her human diet. It would be a nightmare otherwise. What would she even order at McDonald's? The cheeseburger with a side bale of hay? She shuddered at the thought of it.
