Several vibrations roused her. One after the other, incessant, like the barking of a small dog. Mia leaned up and frowned, looking for the source through bleary eyes. She rubbed the sleep from them and saw her phone close by, flashing its message notification at her. Grabbing it, she found that all were from Annie.
Hey, have you seen Rhona? She's not in class.
She's not answering her phone. Text me back asap.
Think she's sick? I wanna check on her, but I can't skip today. Could you?
Mia?
Mia?
Giant centaur girl? You there? Don't tell me you lost your phone in your tits or something. But I'll be happy to fish it out for you.
Mia rolled her eyes and typed a quick reply, then reread Annie's texts and guilt wormed around her. As did something else. Pleasure flickered amidst her concern, tugging her attention down to her lower body. Roshni laid, still asleep, with her body curled around the sheaths and her face half-swallowed by an opening. The black mass of Mia's cock kept her head from being engulfed, in exchange for dousing her in pre-cum.
She shook her head at the sight and went back to her phone. Then stopped and looked again. Last night, she recalled Roshni being tiny, perhaps half the size of her phalli. The doctor was just shy of five feet tall. Mia's sheaths matched her in length and trounced her in girth. She rubbed at a tender spot atop her head with a glance at the ceiling. Getting around would be a nightmare.
Before she could worry about that, however, she wanted to check on Rhona. Yesterday afternoon, the expression on her friend's face, how she seemed hurt and scared by Mia's approach, sank through the centaur's mind.
I'll try looking in on her later.
She sent a quick 'hello' to Rhona, then tossed it onto a chair and extracted herself from Roshni's hug. She left her slumbering on the floor and shuffled from the room, hunched over to avoid the roof. Her bathroom, which had taller walls, felt cramped now and made relieving herself awkward. After floundering, she exited and took stock of what became of her body.
"Oh my god," Roshni's half-muttered statement was adequate.
"Yeah." Mia glanced at her discarded clothes, then at the bag of fresh purchases. She tried and failed to pick them up, until she managed to kick them up with her leg. Most wouldn't fit over her chest, but a few might. She pulled one on and sighed when it snapped against her waist above her navel. The stretch fabric stretched taut over her skin, moulding to the mountains of her breasts and lean musculature.
Why even bother? Modesty meant nothing after everything she had done, and not when her most outrageous aspect bounced and swayed between her legs. All it'd take is a lapse in judgement, a passer-by caught unawares, and they'd be smothered in her dick. Then, if it was a woman, chances are they'd follow nearly everyone else's example. Another otherwise normal woman turned into a slut.
That'd be nice... Mia dropped the bag and chewed her lip. She shouldn't think that. Sleeping with random strangers went too far. Her friends, or acquaintances in some cases, was fine. They consented to it. They liked her, perhaps with one exception, and knew her beyond what she was.
But the thought of turning a stranger into a complete slut just by their being in her path... She went back to her phone, a distraction. Annie hadn't responded, but at eleven AM she would be in class. Rhona had no excuse if she was absent. Mia plopped back onto the floor and stretched her human muscles, then grimaced at how the shirt creaked around her tits.
"What's wrong?" Roshni asked through a yawn. She stayed curled on the ground, cheek propped on a palm and watching Mia with hooded-eyes. Satisfied exhaustion saturated her. From the grin teasing the corner of her lips, to the way her legs splayed open, unabashedly showing off her ruined pussy.
"I messed things up with a friend," Mia said and sent another text.
"It'll be okay," Roshni inched forward and rested her head on the centaur's powerful form, "You're a good person."
"I'm not so sure. I started flirting with her and... I don't know. I didn't even think she'd say no."
"It's to be expected," Roshni ran her fingers through Mia's fur, a gentle, comforting scratch, "But I expect it's frightening. You'd have to be crazy not to be unnerved by someone like you. I imagine some people smell you before they see you, then it arouses them for no other reason. Like yesterday, I haven't felt that turned on in years. Possibly ever. I doubt anyone could really refuse you if you tried."
"Rhona did," Mia said, harsher than she meant, "I even made her cum and she... This isn't right. For all I know she was abused or something. Whatever's happening to me, it's fucking with my brain, Roshni." Her words trembled at the memory of how she'd taken Roshni last night. Even if she had refused, would that've stopped her?
"You're still Mia," Roshni said and stood up. At her full height, she only came eye to eye with Mia's nipples, which gave her pause, "Oh, the injection didn't work."
"No."
"I'll keep working on it. For now, you should work on setting things right with Rhona. I doubt she likes this any more than you do."
"I'll just fuck up again."
"I don't think you will. Just be honest with her. If that means you want to fuck, then it's better that she knows."
"Yeah, I guess," Mia said. Not that it would be easy. Rhona might not even want to see her, much less talk, if her lack of texts were anything to judge by. She wouldn't know without seeing her again, though. The thought picked away at her nerves, joined by her inane desires, both whispering in her ears why she shouldn't and should go. Desire had an easy victory, however, for all it needed was to remind her of Rhona's ass when she walked away, or how it felt on her back. For the wrong reason, Mia left her house.
The walk played like a nightmarish dream. Rhona lived in a small suburb, surrounded by apartment blocks on one side and fields on the other, which led to a small farming district just on the fringe. Mia could've cut through them, even taken a run to distract herself, but the farmers were uneasy around her. They claimed that 'she made the animals restless', so she clopped along the roads. A sidewalk wouldn't fit her anymore, and the road struggled already.
Several times, she missed a car underneath her until the heated metal brushed her sheaths. People complained about it, but soon dwindled as the touches tore at her self-control. Women's whispers rose above the traffic, increasingly lurid as they discussed her genitals. Taller cars were the worst. Her balls rubbed across them, sometimes shaking with the vibrations of a stereo.
It wasn't long until her pre-cum flowed. Her cocks remained tucked away, but the tide wouldn't be denied. Windscreens were splattered in murky pre, and unlucky drivers with their windows down got a heady dose. None complained. Even the nun she spied on a street corner was silent at the sight.
"Oh thank god!" Mia gasped once she was free of the busy roads. The suburb stretched a short way before her, devoid of activity with children and their parents away. A few cars remained, one of which she recognised as Rhona's sisters. It sat in the driveway of a Victorian inspired home. Two stories tall, shingled roof and ornate window planes. The front door was an oaken brown and tiny compared to her towering stature.
She glanced through the first-floor windows and flushed when she realised what that meant. Long breaths, she thought and did her best to calm her heart. At her size, it must sound like a drum. Mia stretched down under the alcove and pushed the doorbell, then carefully extracted herself.
"Hell...o?" One of Rhona's sisters, Jasmine if Mia recalled correctly, gawked at the centaur. Anyone would. Though the novelty of a real-life myth had long since worn off, meeting a house-sized one was fresh. Not even a day old.
"Hi, um, is Rhona in?"
"Yeah, sure," Jasmine didn't move, but for her eyes, which raked in Mia's form with a shameless hunger. Her nostrils flared as she spotted the sheaths, bloated from her cocks, "I'll just get her." The door shut and Mia waited. And waited. She caught hints of an arguments, words that no sister wanted to hear, then silence. Jasmine returned, flushed and wide-eyed.
"She's being difficult," she sighed.
"Her room's at the back, isn't it?" Mia asked.
"Yeah."
"Do you mind if I go round? I just need to talk to her a bit."
"Just don't wreck the fence. Dad might have a stroke and Mom will probably blame us. Don't think they'll buy 'it was a fifteen-foot centaur'."
"No," Mia chuckled, hiding what the statement did to her. She didn't think she was that tall, but not far off either. Two-story houses measured perhaps twenty feet, more with the roof, and she already stood level to the windows... Mia pushed the thoughts aside, though her stomach continued twisting and churning.
"See ya," Jasmine said.
"Yeah." The houses were spaced far apart to her relief. Mia straddled the property line, cautious of the bushes and flowerbeds on either side, and found her way into Rhona's backyard. Her hindlegs stopped a foot shy of the fence at the back, lined by lush shrubberies. Vibrant ivy crawled along the house's drains and framed the window she wanted, through which she saw a naked Rhona scrutinising a shirt. What she wouldn't give to feel it around her cocks.
Shut up, Mia chided herself and fixed her attention on anything beyond Rhona's nudity. She couldn't let herself drink her in. Even glancing at the ebony delight before her was too risky. Her breasts sat high on her chest, slightly flatter than in a bra, but capped with plump nipples that begged to be suckled. Like a pair of delicious chocolates just staring her in the face.
And those hips. Mia sucked in an unconscious breath as her eyes betrayed her, raking in the arch and dip of Rhona's lower body. Her cocks twitched in memory of how her friend's ass had felt on her back, accompanied by the heat of an unsated pussy. Unsated... and unmarked.
"Shit!" Mia jumped at the hiss from the room. She thought Rhona had seen her for a second, then realised that she'd turned her back to the outside. Mia gulped. Smooth muscle streamed down her back and into the cascade of fat on her rump, layered atop a set of thighs designed to wrap around someone's sides. She wiped at her chin. When had she started drooling?
Rhona threw down the shirt. Instead of a simple thump, Mia heard it splatter against the floor. Her friend fretted about, hands in her curls as she stared at something outside Mia's view, "Why isn't it enough?" She said, almost a plea.
