Growing Needs Ch. 14

Then she forced it in. The walls clenched and pushed against her, before freezing in place, a prelude to a violent ripple and gush of fluids. Rhona quivered against her. She jerked upright and held tight to Mia's face, wrapping her body around it and driving her scent into her nose, while her insides spasmed in a deluge of bliss. Her heart pounded through her pussy and reverbed inside Mia's head, urging her to squirm within her.

"That was awesome!" Rhona laughed when she was released, "Oh fuck, my legs won't stop shaking."

"Glad you enjoyed it," Mia said, then yelped at the unusual touch against her underbelly. She tried looking past her breasts, but their size and the shirt obscured her eyes. Rhona peered over the horizon and sucked in a sharp breath.

"Huge," she said, then glanced back at Mia, "But I guess that's normal, huh?" The centaur shrugged.

"What now?" Mia asked, nervous about pushing too far too soon.

"You made me cum, so it's my turn for you," Rhona said and started pulling on Mia's shirt. She slowly got it up and offer, revealing the mountains beneath. They sat proud on her chest, so huge that they obscured her waist, and revelled in their freedom. The border between horse and human was shadowed by them. Tomorrow, it might be hidden entirely. Not even tomorrow, Mia thought when she noticed her nipples stretch further away. Even now, she grew.

Mia pushed the thought away and said, "Go for it."

Rhona didn't waste time. Still balanced in Mia's hands, she opened her mouth and engulfed a teat, straining to take it. Any other time and it could've been mistaken for a cock, such was its girth and length. Rhona's lips stretched wide, her teeth grazed the tender nub, while her tongue rolled across it, enticing the nipple to swell and fill her mouth. Tiny pleasure-filled nubs lined the tit, each a prime target for her curious muscle. She inhaled and slobbered around it.

"So good," Mia cooed and pulled her friend closer, smothering her in tit-flesh. She gagged at the sudden tug, but soon recovered and lathered her spit across everything in her reach. Her arms stretched to encompass what she could, which left much to be desired. The tiny woman pulled back and gathered globs of her spit, then brought it to the unloved nipple. Like a true cocksucker, she bobbed to and fro.

Spit and tears smeared her makeup and clung to her hair. She thrust herself along the nipple, gagging on each descent, while her eyes glued themselves to Mia's. Mascara ran in smeary rivulets down her cheeks, where they joined her copious saliva, more added on every descent. Her lipstick marked her accomplishment at the swollen areolae.

Mia shifted her weight onto one hand and used the other to trace along Rhona's legs up to her pussy. Still sopping wet, she slid along its folds to the clit, circled the nub, then pushed inside. Rhona yelled and fell to a twitching stillness, before coming free with a viscous pop.

"Let me at 'em," Rhona said with a nod toward Mia's cocks. At their present size, the heads came level with her breasts, hidden for now. She nodded and set her down. The air breezed against Mia's tits, calling her hands to them. Pleasure tingled through her body, a prelude to the cavalcade of delight ahead of her. Her members throbbed and slapped her skin, pre-cum already oozed from their tips, as if stretching for Rhona's touch. She stood close to eye-level with them.

"Fuck, they're huge," Rhona said and hefted one in her hands, then squealed at the burst of pre. It covered her head and shoulders, before drooling along her torso and between her legs. She shivered when her pussy was covered. Her body pulsed with need, like every beat of her heart no longer carried blood, but pure lust. Rationality dictated that she couldn't take one cock and live, let alone two. Desire crushed such thoughts into dust.

Nothing would keep her womb empty much longer. Not what she had learned in biology, or even her self-preservation. Rhona licked her lips clean and dove in. The gushing hole was shadowed by a bulbous peak, forcing her to duck underneath to cover it in her mouth. The following spurt filled her maw and forced its way down her throat, so thick that it clung to her insides. She swallowed, desperate to take more.

But she was human. Even latched onto the source, driven by an insatiable, inexplicable need, the flow overwhelmed her. The urethra alone was the size of a grape, and the force that it expelled pre-cum meant it couldn't be contained. After several gags and failed attempts, she gave up. She, instead, stroked what her hands could reach and licked the rest, lathering it in her spit and banishing any remnants of her own scent. The musk crowded her senses, wafting through her like a dense fog.

All the while, pre-cum poured and covered her ebony skin. The ground below became a sloppy mess of slime and mud. Rhona stretched on her tip-toes and tried smearing her tits across the head, then slipped onto her back. As she scrambled to get up, another jet of pre splashed between her legs. Her eyes rolled for a moment in yet another climax.

Last night had been spent aching for this. Every thrust, conscious or not, along her horse-cock dildo did nothing to satisfy her. It couldn't overpower her like Mia's now did. It couldn't dominate her with pre-cum alone. It certainly couldn't make her cum with barely a touch. And she hadn't sampled the greatest part of all.

She rubbed the murky goop from her eyes and stared at the balls several feet away. They swelled before her eyes, descending to the ground despite being metres above it. Mia's legs spread apart for them. Rhona's stomach growled at her. She hadn't eaten since yesterday. What could be better than all those gallons of juicy jizz? She'd heard from Annie how she and Keira had swollen up with cum. And that it tasted incredible.

A looseness fell over her. She didn't relax exactly, but she felt... prepared. Her entire body tingled like electricity crackled beneath the skin. She weathered the storm of pre and latched onto her chosen cock, while its brother twitched and slammed against her head. It almost knocked her back down. Rhona held onto the other for dear life. Strange nodules ran along the shaft, but she didn't question the added grip.

"Suck it, suck it, suck it," Mia said from above.

"It's too big," Rhona whispered back, as if speaking to the cock before her. The words were true. She'd seen watermelons smaller than the head, and that size hardly diminished along the shaft. In fact, she thought and looked to the base, where the leathery sheaths strained around bulbous shapes, it got worse. Rationality whispered for her to leave, while instinct screeched and sang for her to give in. Her body would be a speck on those members. Even now, they dominated every corner of her mind, just by her cradling and tasting one.

The shudder down her spine ran through her pussy. Juices plunged to the muck below. She panted against a cock, drowning in its musk, while the other spattered her back in pre. Her hips rolled to each pulse, grinding along an invisible shaft, and her womb burned. Her ovaries boiled.

One way to stop it, she thought and opened her mouth. When it couldn't go further, she mashed it against the dark glans, felt them give under her force, then her jaw snapped open. She yelped, expecting pain as her jaw distended like a snakes. It never came. Shock and awe gave way to delight when her tongue was doused in pre-cum. Another quiver ran through her body.

Rhona struggled deeper. She wriggled her body, shoved against the ground and pulled on the cock and, exhaustingly slow, she took it further. The cock bent with her body, flexible but unyielding. The gag she expected was another spike in pleasure, then her throat was invaded, already slick from pre, and everything fell into place. All her senses were fixated on Mia.

She hadn't showered. She'd fucked someone recently too. Dried sweat and grime lingered on her cock, from the flecks of crusty seed beneath the head, to the tangy bite of fem-cum further down her shaft. Rhona's tongue lashed around it, sampling everything that she could. Every inch was a wonderfully bitter experience. So strong and virile, it reminded her of cum. But the few times she'd tasted it didn't compare. This was a new plane, another existence entirely.

No one else could satisfy her this way. Her stomach gurgled in invitation, urging her to swallow and stagger onward, until the head popped past her oesophagus. When she tried pulling away, it wouldn't give. She was stuck. Trapped with her jaw impossibly stretched, and her body impaled on her most powerful and recent fantasy. Yet, several feet more stretched before her.

Mia's heartbeat thundered against her own. It was a war drum, resonating in her ears and bones, while Rhona's was a tiny flutter. Just another way that the cocks dominated her. This was her place. She moaned and flexed her body. Mia throbbed inside her and stamped a hoof in approval.

"Keep doing that, oh... I'll cum soon, just keep doing it," Mia said.

Rhona tried speaking but all that came was another moan. It didn't matter. Words didn't matter. She tensed her muscles where possible, tightening the passage down to her belly. Mia pulsed again and undid it all, reshaping her throat to suit her cock. Rhona did it again, holding as tight as possible, while her hands and tongue pleasured everything within reach. Then Mia throbbed. The cycle persisted, teetering Rhona on the cusp of orgasm each time. But Mia was close too.

Through damp eyes, Rhona saw the balls dripping with perspiration. The skin became taut and gleamed from the strain inside. Four oblong shapes so huge that she could curl up inside one in comfort. Her pussy clenched. She could practically live in them, swimming forever in a sea of jizz. Or would it turn her body into more cum? Use her life to create more of Mia's ambrosia.

Her thoughts shattered in ecstasy. The pressure inside her stomach pressed against her womb, which bore down on her cunt and scraped the walls together. She went limp on Mia's cock, yet it held her upright. All its flexibility vanished, leaving a slab of meat-covered iron. She shook and moaned and slobbered, unaware of the world around her. Including Mia's rising moans and the audible rumble in her balls.

The weight in her gut, bloating until she felt she would explode, and the agonising ecstasy with it were all that Rhona recalled when she recovered minutes later. It was the sensation of Mia's cock being pulled free that roused her, bringing to light what she'd done. Her jaw pulled back into place. She rubbed at it, certain the pain would start, but felt only her swollen lips and slop-covered cheeks. She touched her throat. The skin should be loose, stretched by Mia's sheer size. It was smooth as ever.

Her chest. Normal. What about her stomach? Massive. Rhona stared at herself. Remnants of Mia's orgasm ricocheted in her system, a powerful tingle like a low electric current. Her pussy throbbed once more. She couldn't count the number of times she'd already cum, and she wanted more.

Not just more. She craved it all. The mind-shattering sensations of having her face stuffed with a single cock... what would it feel like in her pussy? With both cocks at once. Just the thought pushed Rhona to her legs, which bucked under the new majesty of her stomach, easily large enough to lean on. Mia stepped back.

"Fuck me," Rhona said the instant their eyes met. The ache she expected began, but not in her jaw, or her chest. It permeated her waist and hips, burning hotter the longer she waited. If she took too long, then it would incinerate her insides. Or so it felt. She couldn't take the chance.

"I'm not sure how," Mia said. Rhona's mind darted around. She couldn't just turn around and expect Mia to mount her, their heights didn't match, but there had to be something. Didn't her neighbour have a trampoline? Not a large one, big enough for an only child to enjoy. Certainly big enough for Rhona to lay upon and get fucked.

"Do you see a trampoline next door?"

"Yes," Mia nodded, then realised what Rhona intended. Short on other options, or the patience to consider them, the centaur grabbed it with ease. School was in session and the parents worked, so they had no issue. Once in place, Rhona clambered onto it. The unsteady footing sent her falling upon her belly, just as she wanted, which left her sopping cunt defenceless against Mia's wishes. The height wasn't perfect, too tall, so her back brushed Mia's underbelly as she stepped over. She didn't care when the cocks fell to either side of her.

They had grown. Rhona had a good eye for subtle changes, this was no different. Mia wasn't simply having a growth spurt; she was always growing. Taller, stronger, fiercer, sexier... How could she even think to deny that?

Mia reared back until her cock heads were poised to either side of Rhona's backside. Then the first problem arose of how to get inside her.

"Fuck," Rhona bit her lip, desperately trying to think of how to work it.

"Need some help sis?" Rhona didn't turn at her sister's voice, or answer, "Ashleigh, help move the other one."

"Okay," came Ashleigh's timid voice. She wondered if she was still unconscious. There she laid, half-supported by her cum-filled belly, which jiggled with every motion of the trampoline, while her shemale, centaur friend and sisters worked to fuck her into oblivion. It couldn't be real, yet as she felt pre-cum splatter her pussy, she didn't care. For all that concerned her, she could be chained up in an asylum while cumming her brains out to a fantasy.

So long as Mia fucked her.

Birds scattered at her shriek. Rhona tore at anything in reach, her eyes rolled, her tongue lolled freely, and cum dribbled down her chin as she came. The folds of her pussy, loosened by an entire night of fucking her dildo, became taut as she was filled beyond human reasoning. All logic dictated that she should be pushed around at best, yet her pussy opened. It embraced the dual horse cocks.

The heads burst inside, slamming her walls with pre-cum, before barrelling deeper. Through her cervix and into her womb. They pushed on her oversized stomach, forcing the semen to redistribute. But she was numb to it. Any sensation outside pleasure was shrouded in an iron cage. Her womb stretched and her ovaries flared as Mia's pre-cum found its way into them. Her orgasm reignited and didn't end.

Mia hadn't considered Rhona's sisters. Now she wished she had. Having people around to help was a dream. She rocked her body against the impaled girl, while her siblings pulled her further down. Rhona's pussy didn't relax after entry, locked in a state of ecstasy that burgeoned with every square foot of cock inside her. Her moans faltered into screams, then faded as she came to the trampoline's edge, and Mia's sheaths.

The centaur bucked her hips to an instinctive rhythm. Rhona didn't weigh enough to do much, but she managed short, powerful thrusts. The elastic floor helped, as it forced Rhona to bounce into Mia's every thrust. Mia savoured the sensations of the scraping wetness, of feeling Rhona's heartbeat through her pussy, of having both her cocks buried once again. Nothing compared.

But it could be exceeded, she soon found as Jasmine and Ashleigh joined the fun once more. With their sister insensate, they turned their attention back to Mia. The centaur couldn't see them beyond her body, only feel it as they embraced her hulking balls. Both girls moaned and ground their naked bodies against her sack, uncaring of the grime that lingered on the taut skin. Before she was done, they'd come away reeking of her musk for days or weeks to come.

Or worse. She'd forgotten about the cum she'd shot earlier, pooling within the garden. If they fell in it, then the smell might never go. No, she realised, they'd want more of it. From the source. Mia shivered and mangled her tits as three girls became enraptured by her very existence. She heard the twins whispering to each other, but couldn't make it out.

They didn't keep her guessing long. One climbed onto her balls -- had they really grown that huge? -- and embraced her hindquarters. Then licked her asshole.

"Oh fuck!" Mia jerked at the wetness on her untouched area. It never felt so sensitive before, although no one had tried such a thing before. And she hadn't used it since her growth began, like her body had devoted everything to maintaining her development. Not that the girl could know that. Even so, she did it again. This time her fingers joined the fray.

"How's it taste?" She couldn't tell who it was. Ashleigh or Jasmine. She hadn't spent much time with either.

"Strangely sweet, and a bit sour," the speaker's breath tickled Mia's hole, urging her to buck against Rhona. Her balls churned and swelled, "It feels nice too."

"Think you could fist her?"

"I'll try." She did. Moments later and Mia's spit covered hole opened up to a girl's hand, then wrist and forearm, all the way to the elbow. The girl felt around, as if searching. Then Mia yelled and her entire body convulsed. Her prostate! Whoever it was squeezed the organ, then brushed another. Mia's legs locked into place, lest they crumble beneath her. They squeezed the two glands.

"Cumming!" It was all she could say before everything went white. Her orgasms prior to it seemed pitiful examples of her true prowess. She felt those like crashing waves or explosives lining her body, intense and addictive. This was torture realised into absolute bliss. All her senses went dark, leaving her with touch and nothing else, like her body wanted to experience it all.

Semen raced through her cocks and exploded forth instantly. Yet she felt it all. The sensation of cum rising from her balls, into her dicks, violently swelling them and setting fire to her most sensitive points, cemented itself in her thoughts, before blowing apart at the first shot. Veins and tendons rose across her form, every muscle working in unison to unleash the biblical flood of seed.

Rhona's sister squeezed again. Mia wanted to tell her not to, but her voice wouldn't work beyond incoherent babbling. All she could do was stand there, caught in an orgasm that threatened to tear her mind asunder. And she wasn't sure she wanted it to stop.

Something pushed against her belly, harder with each release. The trampoline creaked beneath her, springs straining until they snapped, and Rhona fell with a hard splat. The pressure on her stomach was gone, then returned after a few spurts. She lost count after the first two. The hand in her ass slipped free, yet her orgasm didn't end. Cum had ceased flowing but her cocks still flexed as if she had any left.

"That was awesome!"
