Mia groaned and shut her alarm off as she rolled back onto her legs. She ran a hand through her hair, untangling any knots from her tumultuous sleep, and sighed at the heavy sensation of her cock flopping about. The fact didn't surprise her, not after the slew of dreams reliving every moment with Annie yesterday. A subtle moan slipped past her lips at the memories.
They say that no one forgets their first time. Mia could absolutely see what it meant, for her body distinctly remembered the sensations from less than twenty-four hours ago. She couldn't act on the desire churning in her dual-bodies, however. It was one of the few moments that she lamented her physiology. If she could just reach her cock, then she might be able to experience a fraction of yesterday's pleasure. Just the thought was enough to make her member lurch in longing.
She blew a lock of hair out of her face and trotted into her shower. It was her best bet at ignoring all the wild thoughts pervading her mind. And perhaps even find a way for it to get her off. Mia gently slapped her face, groaning at how one experience could change her so much. Sex and pleasure were the last things on her mind before.
"Ignore it, and it'll go away," Mia murmured to herself, glancing at her mirror along the way. The click of her hooves paused and gave way to deafening silence, the final step echoing off the walls in a poor attempt at filling the void. Her eyes ran over her reflection, or what the mirror could show. It was seven feet tall, designed for her to see everything about herself. Yet now it barely showed her shoulder blades and lower. She couldn't see her rump either.
Despite her sudden burst of height, her breasts looked no less huge on her frame. They still sat with their lower curves encroaching on her navel, but no further. She took a step forward; the fall of her hoof eerily muted in her ears and brought her cock into view. Just like the rest of her, it had grown. To her relief, it wasn't as extreme as her height gain, though it would be hard to miss if anyone knew her previous size. Even her sheath looked a couple of inches bigger. As were her balls.
She took several deep breaths. Her heart reluctantly calmed its frantic gait, the echoed throbbing fading within her enlarged shaft as well. The centaur felt her breasts, only to release them with a coo of pleasure, before touching the rest of herself. Everything seemed normal, no aches or stretch marks on her skin, which unnerved her. Something like this should've hurt or at least showed some strain on her body.
Mia shelved the notion of a shower and rushed back to her room. There was no disorientation or clumsiness despite her new physique, as if her sleeping body had already adjusted her spatial awareness. She ignored the curious thought and grabbed her phone, then frantically dialled Doctor Roshni's number. The centaur paced around her room, growing increasingly impatient at the ringing on the other end. It eventually went to voicemail.
"Great," Mia muttered and tossed it onto her bed. She took another soothing breath, fully aware that letting herself panic about this situation wouldn't help at all, "And it's really not that bad." She continued aloud, once again taking stock of her enhanced form. Her muscles were still present, and nothing seemed out of proportion. If she had a better eye for it, Mia might've even thought she looked better than ever.
"Always a silver lining," Mia assured herself, recounting her parents' favourite saying. If nothing else, Annie would undoubtedly appreciate the extra inches on her penis, assuming they did it again. The centaur bit her bottom lip. They had crossed a line in their friendship, one that movies would have her believe there's no going back from.
Did she even want to? Mia shook her head, uncertain if she was answering her unspoken question or trying to remove the thought. Either way, she pushed it aside and returned to her usual morning routine.
Her shower was made to give her plenty of room to move. The growth spurt compromised some of that freedom, however Mia remained comfortable as she enjoyed the warm water spraying against her, washing away any grime on her coat and her privates. Fortunately, the mundane task took her mind away from her burgeoning desires. Her cock retracted back into its sheath, offering a begrudging throb.
Mia idly ate her breakfast as she looked over her latest assignment. It wasn't hard, just tedious in the worst possible way. She sighed and set it down, already dreading the boredom that would eat away at her. At least it wasn't due in for another week. A smile teased her lips as she entertained the idea of using her volatile body as an excuse, though it would never work. Her college was infamous for giving very little leeway.
All thoughts were brushed away when she stepped out into the open air. Regardless of boring assignments or her absurd growth spurt, the joy of running couldn't be taken from her. Her legs worked like a fine-tuned machine, pounding the earth into the shape of her hooves, as they carried her forth. Everything was just right that day.
No stray animals or branches to get in her way. The wind was blowing against her back, and the sky was clear. Mia closed her eyes, indulging in her other senses for just a second. Her gallop made her cut through the air, parting it like a bullet. For the briefest moment, she could almost believe that she was gliding. Her nose picked up the mud and bark around her, mixed with the natural wildness of the animals spread throughout. She smiled to herself when she heard a human's grunt.
The expression tightened into a frown as a moan soon followed. Mia slowed her gait, coming to a stop just a few feet from the sidewalk. She opened her eyes and scanned her surroundings, undeniably curious by the strange sounds. The centaur knew that some people liked to fool around in a public space, but she never thought it'd happen so close to her. It wasn't hard to spot the couple amidst the earthy brown and green of the forest.
A girl had her panties hanging from her ankle, while she was being held against a tree. Her partner had his pants around his heels, while his hips thrust wildly against the woman. Both seemed oblivious to the possibility that they would be seen, as the girl made no attempt at subtlety. She demanded more and more, arms and legs locking around the man.
Mia couldn't tear her eyes away. Every moan the girl made was like a shove to her subconscious, forcing all the sounds Annie had made to the forefront of her mind. The centaur gulped and licked her lips, envisioning herself and Annie in much the same position, constantly on the fringe of being caught. A pulling sensation yanked her back to reality as the breeze brushed against her peeking cock.
"Fuck, fuck, fuck," Mia grumbled and rushed away, leaving the couple to their fun.
She stepped onto the campus with a heavy exhale of relief. Crisis averted, Mia thought as she trotted toward the main building. Her friends stood or sat at the base of the stairs, awaiting her arrival. It was Annie who spotted her first, waving to the spontaneously taller centaur. The others turned their eyes to her, smiling welcomingly. Then all their expressions turned to shock as she neared them.
"Hi," Mia said, unable to think of anything better given their amazement.
"Hi," Annie answered and walked over to stand beside Mia, finding that she was barely eye level with the centaur's nipples now, "You've grown."
"I'll say," Rhona added, finally recovering, "What're you now, girl? Eight feet tall?"
"No idea," Mia flushed as the ebony girl stepped close and critically eyed her body, visibly taking note of how much large Mia's breasts had grown.
"Fantastic," Keira muttered, stomping over with a mock scowl on her face, "Why couldn't you just be a giant from the start?" She clapped onto Mia's horse half, which now came to her eyes.
"It's nice that you can still surprise us," Annie said, catching Mia's eye with a wink as the petite girl's hands stroked along the centaur's silky fur.
"Y-yeah," Mia flushed, looking away to avoid her own fantasies, though it was impossible to completely remove the visage of Annie's delectable ass from her mind. She choked back a moan as Rhona's hands abruptly latched onto her breasts. The warmth of her hands seeped through Mia's shirt, which rubbed against her tender flesh.
"How the hell are they so perky?" Rhona wondered aloud, still fondling the huge breasts.
"S-stop," Mia gasped and stepped back, pushing Rhona's hands away. The centaur wrapped her arms around her chest, both to protect them from the dark-skinned woman and to hide her erect nipples. They gradually calmed under her fear of embarrassment, though she remained no less cautious of Rhona's perverted hands.
"Sorry," Rhona apologised and pocketed her hands, "I like to touch."
"I know," Mia groaned, recalling their first meeting after Annie introduced them. Rhona had wasted no time and groped her then as well, though it hadn't been nearly as intensely pleasurable as that moment. Not to mention that it had only been playful all times prior, rather than the flirtatious and despicably licentious touch from recent months.
"Just be glad you have something to grope," Annie added, smiling up at the centaur.
"Yeah," Keira agreed, then glanced at her home. We'd better hurry up. Our classes start soon... I'll race you inside, Mia."
