Growing Needs Ch. 08

"Hey!" Mia yelped, snapped from her reverie as she rushed away. She didn't give Bella a chance to persist and turned, bolting back to her bathroom. The door swung wide, hinges creaking as they strained to hold the wood in place. Mia stared, sidelong, at her reflection. Even those who ignored her enormous presence, or who stood past where her bodies met, could see her cocks with a simple glance from the right angle.

She had to respect those who saw and didn't bring it up. How much restraint did they possess for such a feat? Or was it that they couldn't speak out of shock? Regardless, Mia thanked whatever presence might listen for the reprieve, though it didn't change her circumstances.

Her cocks refused to fall silent. They drooped under their weight, throbbing as more length squeezed out from her sheaths, heads flared and drooling pre all over the floor. Entire inches pushed free as she stared. Her balls remained stable, each of the quartet equal to grapefruits and full to the brink with semen.

How would she react if she was still human? Her throat went tight at the idea. She ran her eyes over the familiar shape of her genitals, even doubled she knew each individual shape well. Puberty led to many interesting thoughts and fascinations. Part of her, the human female, had been fascinated by her equine member. Whether the penis showed or not. That fascination led to her first erection, a frustrating and intriguing moment.

Mia giggled and shook her head. Specialists claim growing boys are fascinated with their penises, but once puberty struck, all manner of urges roar to life for either sex. For her, she grew aroused and dismayed by her body after the incident. She would grow entire inches overnight, until she towered over others and her chest outstripped any girl her age or older. Until she researched it, Mia thought she might have the largest bust in history.

The possibility had returned in force. She turned her attention onto the oversized yet well-shaped mountains on her chest, obscured by the veil of her tight shirt, which seemed to bite harder by the second. Despite, or perhaps in spite of, the straps girding them, her nipples protruded over an inch, determined to be noticed. Dull snaps met her sensitive ears as threads of elastic broke under the pressure. Her shirt rode higher, baring the bottoms of her tits.

"It's like puberty all over again," she mused aloud. Her cocks jerked and lifted higher, veins visibly pulsating, feeding off her simmering arousal. The sensation had faded, now a gentle boil in her veins. Mia breathed slow and deep, soothing the heat within. She could handle this. A bit longer and she would leave, get to class, survive the day and flee home. Tomorrow, she'd meet Doctor Roshni and everything would be fine.

The door swung open.

"Oh no," Mia groaned. There, beyond the reflection of her massive form, stood Bella, face red as ever and trailing her juices. How turned on is she? Mia wondered, then pushed the question aside as Bella strode over, resolute. She came to a stop before the centaur, petite by comparison. The girl stared at Mia's breasts, so close she couldn't see past them. Her hands darted to, and grabbed, the shirt, then shoved it up to reveal the glorious, bouncing visage that was Mia's tits.

The centaur jerked back at the reveal and attempt to pull her shirt back into place. It refused. Her nipples poked far out, pushing against the garment. Their spongy shape held firm, as if they detested the notion of being trapped once more. Mia tried again, but her huge teats insisted against such treatment.

"Just great," Mia muttered, then gasped as Bella's hands found her mounds. Fingers, tiny by contrast, disappeared into the plush hills, swallowed by their expanse. Bella rolled her arms against the heavy globes, eliciting breathless moans from the centaur, whose hands hovered over her chest. A hard shove lifted her breasts close to her face, putting her puffy nipples within reach of her lips. Mia eyed the pink towers. Her throat went dry. She opened her mouth and leaned in, tongue extended. A jolt of pleasure met her touch.

They smacked her belly as the blonde pulled away, releasing the pair. Mia righted herself, stunned by what she almost did. She yelped as Bella jumped up and wrapped her legs around the centaur's human waist.

"What're you... ooh," Mia moaned. The stereotypical blonde manoeuvred the hulking tits until one faced her, before latching onto its stiff peak. Mia's eyes widened at the blazing heat pressed against her stomach. Rivers of molten fluid rolled across her flesh, though she wondered if they were mere inklings of Bella's lust.

What followed came as instances. In one, Mia's head reared back in amazed pleasure. The next, Bella's cheeks turned convex. In another, a stronger moan rumbled in the centaur's chest. Her cocks roared to life, so strong they smacked her underbelly. Bella slurped on her breast. Saliva trailed down Mia's stomach and into her fur. The blonde's popped free with a loud, wet pop.

"Tell me you don't want this," Bella said, "Tell me you're not rock, fucking hard right now. Tell me you don't feel how wet," she rolled her curvaceous hips, rubbing her naked cunt against Mia's skin, "my pussy. How much it needs you. How fucking hot and sloppy and bad it is."

"I..."

Bella raised her head high, until she almost met Mia's chin, "I know people don't like me. They don't have to. I'm a slut. So long as I get fucked hard I don't give a shit what people say. So, miss giantess, you can use me in whatever way you want. You can ram both your huge cocks into my holes, ruin me for other men, make me a mess, leave me craving horse cock for the rest of life... it doesn't matter. Just fuck my cunt."

"Bella..."

Again, the blonde cut her off, "I'm also a huge anal slut. Nothing better than a big cock splitting apart my asshole. Except having another one in my cunt."

"Please..."

"And my throat's the best around."

"Stop..."

"I'm the best lay on campus."

"... prove it." Mia whispered.

Bella jumped down, her spherical tits bounced with her landing, and stared between Mia's forelegs. She froze. Mia looked to the mirror, her jaw dropped, as did a cups worth of pre-cum from her erect phalli. Bella's claim would certainly be tested. Ultimate size queens would flee from the sight - or at least quiver in their boots - presented to Mia and the self-proclaimed slut. What person, or animal for that matter, could handle those things?

In answer, Bella walked under Mia's horse-half. She stopped a few feet in, met by a huge, melon-sized glans. The enormous flare tapered toward the bulbous tip, under which a finger thick hole spewed entire ounces of murky pre-cum. It fell to the floor in an inch-deep puddle, expanding across the hard floor. The head alone looked far, far too great a challenge for Bella. To say nothing of the shaft beyond.

While thinner than the flare, her cocks resembled young Maple tree-trunks. Thick, angry veins twisted across the surface, leading to and from the leathery sheath. Pink splotches broke up the visceral black. Every inch glistened in the florescent lighting, coated in a layer of her trapped pre-cum.

"Oh god," Bella said, realising the monumental undertaking before her.

"Gonna back out?" Mia asked.

"Hell no," Bella affirmed and looked into the centaur's reflection, manic grin spread across her makeup painted face. She's insane, Mia thought, while the blonde all but tore through her own clothes. Insane but hot, the centaur added.

Incomparable to her own, Bella's implanted tits remained a sight to behold. They sat high upon her chest, round and obtuse yet proud in their falseness, capped by hard nipples surrounded in a faded pink. Despite their position, the spheres obscured much of her upper abdomen, leaving her svelte waist on display. Her hips appeared manufactured to match her tits, swelling from her torso to form an erotic hourglass shape. They led down into her meaty thighs and tapered to her dainty feet.

If someone told Mia; 'Bella had surgery to try and match her', she might believe it. The blonde could pass for a human equivalent to the centaur, solely for her figure though. Too much separated them for any other similarities. Mia's cocks, for instance, which throbbed before Bella's gaze, tempting her with their inhuman shape and size.

"If we do this," Bella gulped, "I'll be ruined for everyone else. This... these are bigger than a baby, Mia."

"I know."

"They could kill me."

"Uh huh."

"You could actually fuck me to death."

"You can always stop," Mia said, though her cocks lurched and slapped her in response, as if angered by the prospect.

"No," Bella shook her head, voice softer than Mia had ever heard it. The blonde reached up and took hold of one, its size dwarfing her fingers. Such a simple touch forced a high gasp of pleasure from Mia.

"For some reason," Bella breathed, her words breezing against Mia's sensitive glans, "It just makes me want you more." She inhaled and a splash of fluid fell from between her legs. Her legs quivered. She grabbed Mia's second cock and tightened her grip to keep from crumbling. A burst of pre-cum doused her, accompanied by the centaur's blissful moan.

"Then hurry up," Mia said and stepped forward, mashing her twin dicks against the slut's face.

Bella said nothing. She opened her mouth, wrapped it around what she could Mia's cock, gagged at the shot of pre against her throat and released a muffled cry as the centaur pressed forward. Somehow, through means neither could hope to comprehend, Bella's mouth distended around the unfathomable girth. Her jaw stretched as a snake's would, effortless and smooth, accepting the monumental cock.

It stopped against her throat. Bella's eyes darted in disbelief, while Mia's had closed to savour her pleasure. Both held still, enraptured by the impossibility, then the centaur took another step. With her limbs locked, Bella held her ground as her gullet conformed around an elephantine horse dick.

Mia cracked her eye open and stared her reflection. What she saw sent a tsunami wave of lust through her. The tide crashed through every barrier of restraint she possessed, flooded each mental stronghold she had left and climaxed as another step forward. Bella, her lips stretched taut around a cock too big to seem real, gagged and moaned in a lewd symphony as her oesophagus was raided. A clear bulge piped its way down her neck and into her chest. At the front, a distinct flare led the assault.

Yet her other member hung out in the open.

"Don't forget the other one," Mia said. Or was it an order? Even she couldn't say, but it attained the desired effect. Bella's hands found the underappreciated prick and held it firm. The added sensations made her balls quiver, cum sloshing against the insides, thicker and heavier by the second. Despite herself, Mia couldn't wait to bury them both in this girl.
