The centaur shifted from hoof to hoof. They clicked against the hard tiles and rebounded against the walls, echoing in Mia's ears as she savoured having her cock half-buried inside Bella's tight throat. A passage so thin it shouldn't be able to handle her girth, much less hunger for more, but the slut inched deeper. Saliva and pre-cum mixed together within Bella's throat and mouth. The lewd cocktail coated and dripped from Mia's shaft.
Beside the first, her other dick, from which similar sensations nipped at her senses, was given long, loving strokes. Mia's nipples jutted an inch from her broad areolae, brought to life by the burgeoning ecstasy of her twin stimulus. She pushed forward. Bella's lips forced the foreskin to bundle, and the member to bend against her face. The self-proclaimed slut paused and inhaled, somehow breathing around the immense blockage.
"I didn't tell you to sniff my dick," Mia grunted and pulled away, then lurched forth. Her prick slid inside with ease this time, Bella's gullet open and willing, "Just take it... like the slut you are."
Subtle tremors through her dual body bristled Mia's fur. Since when did she talk to people like that? Even to her friends, she was cordial and professional. She didn't insult them. Didn't order them around. Didn't discourage them.
But Bella wasn't a friend. She was the campus whore. Anyone with a penis or a large enough strap-on had slept with her, whether sober or drunk. Entire fraternities had taken her in a single night. So the rumours claimed. What reason did Mia have for being nice to her? None. If anything, she had the right - the duty - to treat her as dirt. It's what she wants, Mia justified.
The centaur blanketed her qualms in her pleasure. She brought her hands to her breasts, cupping and savouring the plentiful flesh. Their shape belied how soft they were. A set of giant marshmallows, she thought, capped with ripe, delicious cherries. She massaged her tits, cooing softly at the mild warmth her touch brought. It couldn't match the wanton blaze Bella's slurps caused, nor the feverish sensation as she stroked the other cock.
Mia tapped her hooves in nervous delight. Mild quivers rocked her overstuffed scrotum, swinging it to and fro, its cargo carried it far. She jerked as Bella shoved forward. Her lips pressed into the sheath, she inhaled the potent musk and made a gargled moan. The centaur reared back with her hind legs, pulling a few inches free, before slamming back inside. Her prepuce slid into Bella's maw as her balls swung forward to smack the slut's chin.
"Oh fuck, that's... that's good," Mia whispered. She glanced back to mirror as Bella kept moving. There, standing naked underneath her belly, surrounded in a sensual stench alien to a human's body, her third partner shoved her nose deep against Mia's crotch. How did it smell to her? Mia had gone to a farm as a child. The horses were clean but in their natural environment. It had reeked in an oddly pleasant way, such that she couldn't place how she felt about it. Bella had no such issues.
She loved it. No one could mistake the wide-eyes, flared nostrils and bobbing motions for anything but lust. Her senses were subsumed in centaur cock. Bella's body vibrated around Mia's shaft as her hands stroked the second shaft, urging heaping gouts of cum to spurt forth. They landed against the slut's naked chest, covering it in moments. She aimed the following shots to coat herself further.
"Do more," Mia groaned. Bella stepped back, a foot of cock slid free alongside a gush of throat and dick slime, and slammed forward again. Her hands darted to her chest and back to the other prick, massaging a layer of spit and pre-cum into its dark length. It glistened with the mixture and expunged greater amounts in return.
Mia rocked her hindlegs in tandem. She snorted and moaned under her breath, basking in the simple act, made implausibly erotic by her unique form. The centaur tried to imagine the view from a human's perspective, from Bella's to be precise, to picture what it must feel like to stand beneath a horses body, atop of which an overendowed human torso resided, and suck a cock bigger than a leg. All while she stroked its twin and inhaled the brutal musk.
But that wasn't her world. She was the centaur. One that stood twice the height of Bella, endowed with two cocks, four balls and a set of breasts too great for oversized watermelons to compare. Bella's head bobbed back and forth, moaning and gagging on a cock larger than her head. By all accounts, the bitch should've been terrified of the challenge alone, much less succeed in conquering it. Her stomach bulged out as it filled with a constant tide of pre.
Yes, Mia thought as she hastened her thrusts. She was someone to be adored. Not by everyone, only those with the gall to take her like this, to impale their oesophagus and spread their stomach for her. And more.
Mia moaned higher and tugged on her nipples. The blissful soreness in her balls worsened. They grumbled and clenched, shooting greater loads of slime into and onto the slut, who worshipped the sensations. Her once trim stomach was no more, now a slow-swelling mound of viscous cock juice. Though it didn't yet compare to what had become of Keira and Annie the day before.
"Oh god, what the hell am I turning into?" Mia murmured. She wanted to fuck this girl, someone whose familiarity bordered on a stranger. Was it safe? Would she tell others about it? What if they wanted to try as well?
The centaur pinched her nipples and yanked on them. She couldn't think like that. Not now, not ever. Annie and Keira - and now Bella - were already willing. Why would she want more? A rhetorical question. The answer pervaded her entire body, from hoof to tail to her head; pleasure. If a threesome had been incredible, then how about a foursome? Or if she took five girls at once?
"Stop that," Mia snapped under her breath. She grunted and plunged hard into Bella, cramming the girl's face into her crotch and forced her to hold the pose. Her neck craned up, its shape overridden by that of Mia's cock, while a throbbing tube led the way down into her pudgy abdomen. The centaur pushed forward, pulling the slut along until they were against a wall. Mia planted her hands there and kicked with her hindquarters. Her rear rose high, extracting almost two feet of dick, and slammed down. Bella retched at the violent penetration.
But her pussy rained harder than ever.
Mia panted, her breath condensing against the tiled wall. Its surface reflected her visage with a bleared out sheen, offering a peek at her flushed features and wild-eyed desire. Her pink hair scattered across her face, clinging to her cheeks with the budding beads of sweat, while her lips hung apart. She looked untamed, like an animal in heat.
"It's your fault," Mia said, glancing back to the mirror and at Bella, whose face was smeared in sweat, tears, cum and spit. That's right, the fault lied with Bella for riling her up, and with everyone else in the classroom. None did anything to help alleviate her growing unrest. She couldn't help but feel this way because of them. Which left the responsibility of relieving her to Bella. Who better than the campus slut?
But this would be a one time indulgence. She'd see her doctor tomorrow and get a grasp of the situation, then she could work on controlling it, if nothing else. For now, however, she would gladly abuse Bella's body until the slut gave out or she was satisfied. Just this once.
Mia repeated her earlier plunge. Her balls swung forward, carried by her thrust and their immense, growing weight, to slap Bella in the chest. The slut moaned and swallowed around Mia's dick, overtaxed throat working around its enormity, urging it to swell her belly further. Over four feet of cock, riddled in veins larger than novelty pencils and capped in a head wider than a melon, rammed down Bella's gullet and into her stomach. The organ sloshed with Mia's abundant pre.
"That's right," Mia breathed. She ground her tits against the wall, her hands preoccupied with maintaining her balance as she kicked back and slammed into Bella. The smack of her balls against flesh made her cocks throb fiercer, "Take it you fucking slut. Suck all that horse cock. Stroke another. Make me cum down your teeny-tiny mouth."
Bella's moans heightened at the degradation. She angled the second cock toward her chest and wrapped her faux boobs around it. A sublime coating of their fluids lubricated the prison as it stroked up and down. She kept one arm around her bosom to it in place, while the other caught Mia's balls and massaged them in turn. Mia moaned in approval and hastened her bucks. Each time she slid down, her cocks felt one another through Bella's tender skin.
"I'm gonna cum soon," Mia said, "Then I'm gonna fuck you properly. I'm gonna inflate you with my cum. I'm gonna cover you in it. You're gonna look pregnant with my babies. My foals." Bella's suction strengthen as she leaned into the next thrust. Her arm bobbed her tits as the spare hand encouraged a greater load. Each oval ball swelled with the impending release, expanding by the second. Larger than a soccer ball, then a basketball, then to a prized pumpkin.
How many trillions of sperm was she producing? Her balls were tight, her black flesh shiny from the strain of its four burdens, all churning and grumbling for release. Bella's lips travelled across near every inch of Mia's cock, sucking as it withdrew and gagging upon entry. Drool hung off her chin and broke against her tits, aiding the second behemoth in fucking the obtuse mounds. Regardless of authenticity, Mia savoured the dual attentions.
"Fuck," Mia bit her lip and hung her head, focusing on maintaining her control, "Not yet, not yet." Beneath her, a murky puddle spread. The product of her and Bella's copious fluids, too much for any one person to create. Too much for an orgy to create. Only she, with her mind addling musk and cocks, could bring about something as spectacular as this.
She paused with her prick buried within Bella. The slut retched and squirmed, but she didn't move away, despite her nose being thoroughly trapped against Mia's crotch. Fine hairs tickled her nostrils and painted it in the centaur's scent. Her throat retaliated and tried to push the giant out, to no avail. Its flared tip remained lodged in her rounded stomach, the veins throbbed against her heart, overpowering its beat with Mia's own, while its shape dominated Bella's chest and throat. Bella took a long, ragged breath as Mia reared back.
"Cumming!" Mia announced. Her flare, already enormous, exploded upon its entry into Bella's stuffed belly. Its shape became defined against her gut. The rest followed suit. Mia's balls seized and retracted against her body. All four fed one another with an endless sense of bliss. They pulsated and sloshed against each other.
"Oh, fuck!" Mia's hands flung to her tits and held them against her face, stifling her ecstatic shriek. The onset of cum slowed in her mind, as though her sperm rich gunk were too thick to be expunged properly. It welled up in her balls and shoved into the tubes. They separated between the two members, though the majority travelled through the first. Had the second not finished forming yet? She wondered in her blissful state.
She couldn't estimate how much jizz traversed her shaft. Litres? Gallons? Bathtubs? The thought seemed ludicrous, yet her very existence defined such a term. Her cocks burgeoned as the load moved, shrinking when it passed from inch to inch. Mia's shriek sputtered as she tried to moan. Her seed was hotter than she'd ever felt before. It set light to her nerves, which fed on the agonising bliss.
An orgy of sensations assaulted her hyper sensitive form. The moist, tight seal of Bella's throat, the bitch's rigged tits, the magma rising through each of Mia's cocks, her balls pumping said magma, the trills of ecstasy dancing across her skin, her moans and screams vibrating her huge chest, to the simple act of her fingers sinking into her boobs. Trapped in slow motion, within that hive of bliss, she would swear a second orgasm was building already.
Then everything went into fast forward. Not the type where it skips entire seconds, but where time simply steps up a pace. Her cum rose to the flares of her pricks and bulged out the peaks, before exploding into and onto Bella. Mia's mind dimmed as the sensations shifted into overdrive. Everything she had processed in a careful pace, now bombarded her. Fittingly, it felt like a series of bombs detonating across her form.
