Growing Needs Ch. 04

Author's Note: This was a request by my reader, Sovietspyder.

"Hmm," Annie sighed, breath washing over the nape of Mia's neck.

"You better not cum on my fur," Mia warned, twisting her head around to glare thinly at the petite girl.

"Then stop moving like that," Annie retorted, grinding her hips in tandem with the way Mia's muscles worked beneath her. Her grin made it clear that she knew what she was demanding.

"Remind me again why you can't walk?" Mia sighed, continuing to trot along the path leading to her home.

"Because you gave me this," Annie grabbed Mia's hand and laid it on her round middle, which jiggled and sloshed audibly. If the wind blew just right, Mia could smell her cum on Annie's breath.

"Pregnant women still walk," Mia countered, looking dead straight to avoid letting on how nice the constant motion felt. Even the spreading dampness was somehow pleasant, even though she'd have to wash it out from her fur before bed. She didn't want to risk the aroma setting her off in her dreams. Not after seeing her sheer output.

"Yeah, but not when they have a hot, tall and sexy centaur girlfriend to give them a lift," Annie chuckled, leaning her head against Mia's shoulder blades and breathing in her scent.

"Are we?" Mia frowned, stepping onto the farmland.

"What?"

"Are we girlfriends?" Mia clarified, pausing to look over her home. It was a single floored building, just over one story tall, and designed to suit her needs. Grass surrounded it with only a single dirt path breaking up the greenery. It wouldn't be a bad place to have a family, she thought.

"Well, yeah. I don't want to share you with anybody. And I like you for more than just your body," Annie said, wrapping her arms around Mia's waist and locking them tightly, "I think that counts as being your girlfriend. Why?"

"I just..." Mia hung her head and resumed her walk, "Everything's really unclear right now."

"You mean your growth spurt?" Annie inquired.

"Yeah," Mia nodded, noting that the ground was lower than ever, "It's got me worried, you know?"

"What if you grow bigger than a house?" Annie laughed, "Or a mansion?" Despite herself, Mia couldn't help but chuckle at the idea.

"I'm serious," Mia restrained her next giggle, pushing the absurd thoughts from her mind, "How could I have a relationship if I get that big?"

"I wouldn't care," Annie asserted, strengthening her embrace.

"Even if my dick got too big to fit inside you?" Mia turned her head to look her friend in the eye, catching a hint of disdain in her dark irises.

"I'd... I'd miss it, sure," Annie relented, ceasing the movements of her hips, "But it's just a bonus. A really big bonus."

"Yeah, I've heard it before," Mia sighed.

"Really?" Annie's eyes widened, and curiosity bubbled in her voice, "I thought you were a virgin when we fucked."

"You know what I meant," Mia rolled her eyes, "No sex doesn't make for a good relationship. Far as I know."

"Who said we couldn't have any fun?" Annie teased, pressing her lithe body against Mia's human back, while sinking her curvy ass against the equine half, "I could jerk you off with my body, or lick you. Hell, if you got that big, I could finger you."

"Eww!" Mia cringed at the thought, while thanking Annie for her weird mind. Anything more and the centaur might've sported another erection.

"What? I think it's pretty hot."

"We are not doing that. Ever."

Mia stepped inside her home of almost a decade. She scraped any mud from her hooves, while pulling Annie off her back. The walls were a warm oak, contrasted by the white trimmings, and lead into her tiled kitchen where a round dinner table sat. Four chairs rested around it, though she rarely had a need for them. From there, it moved into her living room. A coffee table, couch and large tv occupied the space, though only one of the three had any use for Mia.

"Wow, your place is nice," Annie commented.

"Yeah," Mia agreed, "Gets lonely sometimes, though."

"That's why I'm here," Annie smirked proudly as she plopped onto the sparsely used couch, "How do you clean everything anyway? Can't be comfortable to get so low."

"I have a cleaner come in every month or so," Mia explained, pulling open her pantry to set up some snacks. Almost everything was taken care of for her, unless she made a specific request. Her groceries were always delivered and unpacked while she was at college, any housework was done at the same time, and they even used to have a chef prepare her meals. It had taken three years to get them to tone back.

"Don't know why you want a job then," Annie noted as Mia entered the living room, two cans of soda and a plate of cookies in hand. The centaur folded her legs and descended to the carpeted floor, while she idly grabbed a cookie.

"I explained earlier," Mia mumbled around her mouthful.

"Oh yeah," Annie took her own and took a bite from it, looking around the room. Conversation dimmed to a silence as Mia turned the tv on, flicking through channels for something to watch. Though she didn't speak, or truly acknowledge Annie's presence, Mia was glad to have her around. Being alone meant having to think or study, neither of which sat well with her.

"Go back!" Annie exclaimed, "I love this show."

"Steven Universe? Isn't that a kids' thing?" Mia inquired, though she shrugged and set the remote down.

"Well, yeah. But it's cool," Annie insisted as she slid to the floor, crawling over to drape herself over Mia's horse-half, "Not as cool as you, but still pretty awesome."

"You make me sound like a superhero," Mia snorted. She leaned into Annie's body slightly, savouring the warmth and touch.

"Well, you could be."

"Yeah, sure."

"No, really. I mean, you've got the origin story and everything. Now you're growing taller as well. You could totally be one," Annie gushed, "What'd your alter ego be, though?"

"Horse Girl," Mia offered dryly, "Centaur Gal, The Incredible Semi-Human..."

"Spoil sport," Annie chided her, "I think you'd look sexy in spandex."

Mia arched a dubious eyebrow, "I doubt a horse would look good in spandex."

"Sure, it would," Annie assured her, patting the furry lower body, "Especially your cock. Imagine it bulging out your suit, just enough detail to get me going."

"You realise if I became a superhero, you'd technically have to share me with everyone, right?" Mia smirked when Annie's eyes widened.

"Never mind," the petite girl quickly declared, turning her attention back to the screen. Mia's lips remained titled into a content grin as she did the same. They remained there for hours, leisurely eating the plate of snacks as they talked about whatever caught their attention. Only the bright burning gold of the sunset alerted them to the time. Mia stood and stretched.

"You should probably get back home," Mia groaned as her joints popped satisfyingly.

"Guess so," Annie reluctantly agreed, "I do have a test coming up."

"Want me to run you back?" Mia inquired, kicking her legs out to make sure they hadn't fallen asleep.

"Yeah, sure," Annie accepted with an excited, mischievous grin. The centaur only sighed at her obvious reasoning and walked through to her front door. Rather, she tried to. Mia grunted as her forehead struck the doorframe, leaving an obvious mark in its wake.

"Ow," Mia grumbled, rubbing the spot with a pained and confused frown, before she noticed that she was taller than her doors. They were specifically designed for her, being a foot over the usual average.

"You alright?" Annie walked over out of concern, only then seeming to notice that Mia's chest was higher than before. The tip of her head barely reached Mia's breasts, which more than matched Annie's head in size.

"I'm too tall for the doors," Mia lamented, lashing the other concerns away from her lips. It was bad enough that she might worry Annie with this unconcealable development. She didn't want to project anything else onto the girl, not when they were just conjecture on her part.

"Yeah, and I can't reach your boobs with my face," Annie similarly mourned.

"What?" Mia barked, caught off guard by the response. She couldn't resist laughing at the petite girl, who now looked almost half Mia's height. Just ignore it, Mia told herself as she indulged in her friend's predicament.

"Don't laugh," Annie pouted, "Now I can't suck your nipples whenever I want to."

"No worries," Mia cajoled her giggling into calming down as she hugged her small friend close, "When we're alone, I'll gladly pick you up to get at them."

"Are you making fun of me?" Annie scowled.

"Nope," Mia said and lifted her until her face was level with the huge mounds, "See?"

"Whatever," Annie sighed, a grin teasing her lips, "I'll hold to your word, got it?"

"Yeah," Mia nodded and lowered her back down, "Thanks."

"Don't mention it," Annie smiled, "So, uh... I was thinking... just now... that maybe I should stay over?" She offered, shyness cooling her features as she tried to keep her eyes locked on Mia's, awaiting her response.

"Don't you have that test to study for?" Mia objected, though her reluctance was obvious. She could all but hear her anxiety muttering in her subconscious, waiting to fill her head with fears about her uncontrollable physiology. Like an angry snake lurking in the shadows, she thought. The last thing she needed was to be left alone with it.

"I can do that wherever."

"Okay," Mia smiled gratefully, "Just tell your family you're here. Don't want to be suspect number one if you turn up missing."

"Who the hell would mess with an eight-foot-tall centaur?" Annie chortled, though pulled out her phone and called her parents. Mia ducked into the kitchen and pulled out what she needed for dinner that night, all while listening to the tone of Annie's parents. It was warm and strict, even through the static of a speaker, a combination that only parents seemed capable of pulling off. The centaur reached into her shirt, grabbing her cell phone from her tight cleavage. She smiled softly at the image of her parents.

"Right, that's all set," Annie announced, stepping inside to stand with the centaur, though she struggled to peer over the kitchen counter. Anything that Mia used regularly was adjusted for her previous height, forcing her to hunch over to make sure she could reach everything, "What'cha making?"

"Figured I'd do a mushroom risotto, seeing as how I have an important guest," Mia explained as she worked her knife with experienced hands. From the right view and light, faint scars and callouses were visible on her fingers, a testament to her time sustaining herself.

"Hot, cooks, and knows how to fuck," Annie listed off, "Complete package."

"Thanks," Mia grinned, staring down her friend... "Could you do me a favour tonight?"

"Sure," Annie quickly agreed.

"Measure my height every hour. I think I'm growing constantly. Not just overnight," Mia explained, almost certain that the mushrooms below her were further away. She frowned at the thought, hoping that it was just that; a thought.

"No problem, but I want something in return," Annie lowered her voice, sliding closer to the centaur until her bountiful hips pressed into Mia's leg, "I want you to fuck me again."

"That won't be hard," Mia laughed, setting her knife down to fold her human body in half, until she was almost within Annie's reach, "Especially if you show me that ass."

"Gotta admit, I never pegged you for an ass girl," Annie noted, leaning up to press her lips against Mia's, inhaling the soft, earthy tones of her musk, "Want to fuck it sometime?"

"I'd tear it apart. For real this time," Mia added, recalling how implausible it was for her to penetrate Annie at all. The last thing she needed was to put her in hospital, or possibly kill her.

"You'd be surprised what people can fit up there with enough practice," Annie revealed, "And I don't mean right away. Let's wait until you're tired of my pussy."

"Like that's ever gonna happen," Mia scoffed as she slipped her hands into Annie's pants, feeling her naked ass cheeks. It was muggy inside her clothes, the source of which she had no misconceptions about. The centaur dug her fingers into Annie's ass, breath hitching at how firm, yet supple it was. A gentle sigh of pleasure caught her attention.

"Fuck, your hands feel good," Annie cooed, pushing her rear out and into those perfect fingers, "But I know something that'll feel even better there." There was no doubt in Mia's mind as to what she meant. She bit her lip and glanced at her mushrooms. Her stomach growled, unhappy with the meagre offering of cookies.

"After dinner," Mia eventually said, pulling away while raking her nails gently along the smooth flesh, "But no penetration, or sucking, or anything that might set me off. Okay?"

"Seriously?" Annie pouted. Her leg twitched as if ready to stomp.

"We've got the day off tomorrow," Mia reminded her, "So, once everything's finished here, and I get my clothes, we'll have some fun... Maybe tonight, if you behave."

"Yes, Mom," Annie rolled her eyes, then wrapped her arms around Mia, "I can wait. So long as you're mine, then I don't care." The centaur looked down, though she couldn't see her friend over the swell of her bosom. A laugh rocked her chest as Annie leaned back to peer up at her.

"How's the view?" Mia chuckled.

"It'd be better without the shirt," Annie criticised, sliding her hands under the tight garment, "And the bra."

"Naked sleepover?" Mia inquired, biting back a moan as Annie's hands moved across her skin. Her body seemed like it was trying to overcompensate for her growth spurt, saturating her body with nerve endings, yet the only pain she felt was from the door. It almost made laugh to think that her body somehow knew when it was being touched, responding like an eager dog or cat.

Annie face lit up, "Really?"

"We've fucked, I don't think it's any worse," Mia reasoned, licking her lips as Annie's fingers found her bra, nails gliding over skin along the way,

"You sure my big, beautiful ass won't distract you?" Annie teased with a shimmy of her hips, bring Mia's eyes to her curvaceous rear. No matter how often she saw it, the sheer scope never failed to amaze her. A waist so small that only Barbie could beat it, that exploded into hips any mother would be proud of. Not to mention the shape. Mia returned her hands to Annie's cheeks, before slipping her pants down to let her drenched snatch into the air.

"Fuck, Annie," Mia gasped at the musk that filled the space around them, "How wet are you?"

"Enough to fill a cup," Annie moaned as she stepped out from her pants, "But it can wait a little while." She added as her fingers worked to unhook the myriad of clasps keeping Mia's breast confined. They barely had any give, forcing her to strain just to undo one.

"A little while," Mia agreed, barely hiding her desire as her cock pulsated inside its sheath. Her belly snarled at her arousal, cowing it into submission, "But first, I really need some dinner."

"Yeah," Annie nodded, then yelled victoriously as she undid the final hook, "But there's no harm in an appetiser, is there?" As she spoke, she lifted the shirt up until Mia's tits burst into the open. The petite girl reached up on her tip-toes and captured a nipple in her lips. She immediately suckled on it, just like a baby would, then let go just as quickly.

"Tease," Mia gasped, glancing down at her saliva slickened nipple. It twitched against the open air, seemingly seeking out the warmth from a moment ago.

"You know it," Annie giggled, "We can do that and more later." She promised with a sensual smirk, eyes smouldering with her burgeoning desire.

"I take it back," Mia shook her head, pulling her shirt off and tossing to the side, "You're a fucking cock tease. Now shoo, I need to make dinner." She waved her hand at Annie, urging her back into the living room. The small girl pouted, but she did as she was told and sauntered away, her ass swaying widely before Mia's eyes. Every other step offered a tempting glimpse of Annie's tight pussy. The centaur took several deep breaths once alone.

If she were normal, she would've been fingering herself. As it was, her cock was semi-erect and already leaking pre. Mia returned to her task, focusing on anything but her prick and the hottest ass that was just a few feet away. Once her stomachs were sated, then she could indulge as much as she liked. She shook her head, sighing at how impossible her libido was becoming.

At this rate, she'd be getting erections in public. She almost did. Mia pinched the bridge of her nose, wishing that it would cut off the flow of desire, but of course it didn't. The best she could do was try and ignore the constantly simmering lust, at least until the time was right. She took a long inhale through her nose, testing the aroma of her meal, however it was tainted in Annie's potent musk. It would be almost impossible to resist her all night.

"Dinner is served!" Mia announced, setting a regular sized plate in front of Annie, while she settled down with at least four portions worth.

"Jesus," Annie gawked at the sight, "I know you need to eat a lot, but that's a fuck ton."

"I know. If I was still human, I'd be fat as a whale by now," Mia laughed, patting her trim belly.

"Well, I mean, look at me. I got this big off nothing but protein," Annie joined her, patting her still engorged stomach, setting her surface jiggling as the cum sloshed about inside. Her eyes strayed to Mia's underbelly, thinning in seductive longing. They ate in relative quiet, though Annie couldn't resist moving to show off her lustful pussy to Mia. The centaur's eyes strayed often, each time becoming harder to look away.

"I'm stuffed!" Annie announced, leaning back into Mia's couch, legs spread wide and her pussy on full display. Her arousal had dissipated with the meal, however it remained as an ember, always ready to catch any hint of fuel and explode into a wildfire. It was obvious by her eyes, always glancing fitfully to the centaur. Mia could practically read her thoughts with just a glimpse. She could almost smell it as she walked into the kitchen, only just remembering to duck her head under the doorframe.

Mia found her tape measure and brought it back in, "Annie?" The petite girl looked up, then stood and walked over.

"Every hour, right?" Annie inquired, taking the tape and sliding it down to Mia's hoof. The centaur stepped on it as her friend, and failed, to reach the top of her head. Mia took the measure back and finished the job, "Holy fuck, Mia. You're eight feet two inches."

"Seriously?" Mia blinked disbelievingly at the statement, then recalled the door. It made sense, but it didn't mitigate the shock at all. How could she have grown so much over the day?

"Want me to measure something else?" Annie grinned, waving the tape measure around her lustful smirk.

"No," Mia shook her head, dreading to think of how big her cock might be, "Let's just find something to watch."

"Can we snuggle?" Annie asked, fluttering her eyelashes.

"Sure," Mia nodded, then sat on the floor. She gestured for Annie to sit in front of her, the small girl fitting perfectly against the centaur's human body. Mia's breasts rested heavily on Annie's head, their soft expanses deforming against her, yet they retained most of their shape. Her friend didn't mind in the slightest, nuzzling up against them with a content sigh.

An hour later and Mia was measured again. Half an inch was added to her already formidable height. The next hour and it was half that amount, much to her relief.

"Okay, we can stop now," Mia said after seeing the time.

"You sure?" Annie yawned, then glanced at her phone; 3:22AM, "Oh shit, yeah." Mia stood, taking the warmth of her breasts from her friend. They looked bigger, though it was hard to tell. At least their growth was slower than her height.
