Mia yelped as the automatic doors slid shut around her rump. She hastily stepped forward and sighed, looking back at her larger than life body, which had only grown further since last night. The centaur hadn't dared measure herself again, fearing how many inches she'd gained in just a few hours. At least she wasn't tall enough to hit her head on her home's ceiling... yet.
"Don't look so down," Annie pepped up, her small face peering out from beneath Mia's floor-consuming breasts, "We'll get you some new clothes, some food and then I can try out my top-secret massage."
"Let me guess, it involves my dick?" Mia asked dryly, though she couldn't resist a smile, "Come on, I'll have to pick out new stuff now." She ushered the petite human forth, while skittishly glancing around at the onlookers. Locals were used to a centaur walking through the mall, although not one that stood over eight-feet tall and had breasts as big as watermelons, which forced her present shirt to stretch futilely around them. The fabric didn't even graze her belly anymore.
Mia was almost relieved that she didn't need to wear any pants. It meant all the eyes that followed her sheath as she walked were insignificant to her, except for the girls that pointed to it and giggled. Their laughter reached Mia's ears without fail, and they always made her face burn. She ducked her head to avoid looking at them, but that only put Annie's hypnotic ass in view.
It filled her view despite being more than six-feet below her. Mia's gaze drifted between each cheek, watching one rise and fall, before the other mimicked it a moment later. When she stops, it looks like a heart, she thought tracing every curve with her eyes. The centaur forced her stare onto the stores, watching for the one place that would stock her clothes.
"Mia?"
"Hmm?" Mia looked around at the sound of her name and soon found the speaker, "Oh, hey Keira!" She waved her over, eager to have another friend around. One that wasn't constantly trying to get into her proverbial pants.
"What happened to you?" Keira gasped as she walked up to the centaur, leaning her head back to stare at Mia.
"Uh, still growing, I guess?" Mia shrugged.
"Makes sense," Keira muttered, looking her up and down with a critical eye, "But why'd your tits have to get so much bigger as well?"
"Pfft, you wanna hug 'em, I know it," Annie piped in, smirking knowingly at the athletic girl.
"Annie," Mia groaned, "So, what're you doing here anyway?"
"Looking for some new sports gear," Keira answered, "I take it you need new clothes."
"It's that obvious?"
"It is when your shirt looks more like a bra," Keira laughed and pointed to a sporting good's store, "That place sells really good spandex."
"I, uh, I'd prefer some normal clothes," Mia replied, nodding to her usual place.
"You're just gonna end up outgrowing them," Keira rolled her eyes. The centaur shrugged and walked to her normal store, her friends following close behind. They strolled through the plus-sized aisles, grabbing the loosest tops they could find.
"What about this?" Annie held up a sleeveless shirt with slits down the side, made to show off side-boob.
"I... think not," Mia chuckled, and picked up a more conservative vest. There were enough eyes on her without showing off unnecessary skin. She slung a few more shirts over an arm, then headed to the changing rooms, leaving her friends to peruse the store without her. The centaur paused and turned back to Annie, "Don't start anything."
"Who do you think I am?" Annie feigned a hurt expression, but she nodded nonetheless.
"Start what?" Keira arched an eyebrow, glancing between them, before stepping up to the centaur with a cocky smirk. She inhaled and released it in a sigh, moving slightly closer, "You smell good, Mia." The track star breathed in again, taking it in deliberately slow, as if sampling the finest bouquet or wine, or an intoxicating perfume.
"It's sexy," Keira commented.
"Uh, okay... see ya in a minute," Mia ducked into the room and shut the door, closing the two out. The roof was fortunately higher than average. She frowned and raised an arm, then sniffed at her armpit, further deepening her wrinkled brow. Nothing smelled different. Was Keira just flirting? She shook her head and hung her potential clothes on the rack, before pulling her tight shirt off with a sigh of relief. Her breasts bounced in their freedom.
The centaur looked at her reflection in the customary mirror. She couldn't see her face, or her shoulders, but her chest and sheath were in plain view. Her size did nothing to affect the shape of her breasts, each just as pert and full as when she was a teenager. Even without a bra, they sat upright, and her nipples poked out at the very peaks. If she was human, what man would be able to resist her? Not that it mattered.
She glanced to the door and listened closely. Mia's hearing was better than most, for reasons that none of her doctors could discern. The best that they could guess was that her human attributes had acclimated to her horse-half, somehow augmenting her senses. She breathed softly and listened to her friends, envisioning them.
Mia smiled at her reflection and began to try on her potential purchases. Men didn't interest her, that much was clear after her times with Annie. One of her hands groped her breast, fingers sinking deep into her supple flesh, as she recalled those instances in vivid detail. The centaur pinched her arm, silencing her thoughts.
"This had better not be a recurring thing," Mia grunted and rubbed the mark her nails had left, then grimaced at the sight of her sheath in the mirror, noting that her tip had peeked out. Even with Annie safely hidden behind a door, she still set her off. Mia ran a hand through her hair, finding that, much like her entire body, it had grown greatly. Her nails also desperately needed a manicure.
A girl's day out, she thought with a giggle. Mia couldn't remember the last time she'd had a day like that. High school was spent in and out of testing while avoiding attention, something that was impossible being what she was. She lowered her gaze to stare forlornly at the long shirt in her hands. It would be too small for her in a day if this growth spurt kept up, maybe within an hour. The centaur tossed it onto the bench that had no use for her.
If life gives you lemons, make lemonade. Mia recounted the old proverb in her head, then chuckled under her breath. Whatever, she decided and pulled on another one. It was tighter than the last and was stretched taut around her chest, despite being the same size as those before it. Making lemonade was easier said than done.
Mia sighed as she set down the final top. They all fit, though that wouldn't last for long. It was strange, but she could practically feel her body growing. She rolled her shoulders, groaning at how the shirt clung to her breasts. There was no doubt that it'd be useless in a day.
"Might as well get a poncho," Mia sighed and put the other clothes on their hangers. She saw no reason to buy more than one, not when she'd only be back for more, "Hey guys!"
"Here!" Keira called and slung something over the door. Mia grabbed it and found that it was a spandex top.
"I told you..."
