#6 of Spreading Transformation (ARCHIVED)

Part 6 of my series! Dean finds a bit more of his wild side as Sarah contributes.


"Mooooooauuughhhhhhhh" he bellowed as his mind was overwhelmed with lust. His eyes rolling into the back of his skull once more, but this time not from pain but from pleasure. He arched his back even more sharply as he drove himself into the rabbit. His cock began throbbing more severely, its length distending and turning purple as it was flooded with blood. As it throbbed its base started to thicken, growing with every heavy beat of his heart and convulsion of his small balls. Soon it was prying more and more of apart the rabbits nether lips apart. Their weak throbbing began to liven at the new stimulation.

Neither Dean nor Sarah could see it but they both could feel it as he began pushing deeper into her hot wetness. Sarah grabbed handfuls of his coarse chest fur with increasingly tightening hands as she braced herself. She felt like she was being penetrated for the first time all over again as she felt him throbbing and growing slowly inside of her. The slow progress of his cock stimulating her even more sensually and deeply than James's fast heavy thrusts. She felt him pushing against her walls in a very real way for the first time since she found him. She moaned and arched her own back as she rode the bucking bronco below her. Juices began to spill down her legs as her body was slowly filled with hot throbbing meat.

Deans hands grabbed the rabbits wide hips roughly as he pushed into her with all his might. He felt himself becoming heavier, thicker downstairs as his manhood filled her, pushing into places yet unknown for the raging lust-filled bull he had become. As his penis grew his balls throbbed, they sent something between pleasure and pain to his lust-addled mind. Playing catchup his grape-sized balls began to grow with each throb in their convulsing wrinkled scrotum. Soon they were stretching his sack until it was tightly wrapped around the increasingly virile orbs, his skin stretched thin. His balls grew to the size of golf balls. The skin of his sack turning the same dark brown as the rest of his skin as it struggled to contain his roiling, heaving ball flesh.

"Mauuyyyy....my ballllsssuuuhhhhhhhh" Dean managed to moan through the ever-growing haze of lust. His muzzle spraying a cloud of spittle as it clenched shut in agonizing pleasure. His huge flat teeth grinding as he was filled with immense lust. His giant new nose breathed in her scent, it was driving him wild. It didn't help that he had trouble controlling the giant new tongue that occupied his long bovine muzzle. It was all he could get out as his nuts continued to throb and convulse, sending waves of throbbing pleasure through his body and his deeply submerged cock.

His balls continued to throb and grow as new potent bull seed roiled within them. They gained an almost unlimited capacity for production as they ballooned. Bigger and bigger until they were the the size of two large oranges between his twitching thighs. His sacks skin thickened to accommodate their hefty weight, it's skin still pulled tightly across his throbbing balls.

Sarah was riding him now, her gyrating hips rubbing herself heavily against his heat. Liquid poured out of her, streams of her lubricant mixed with his pre gurgled out of her cunt as she bounced up and down on the bull. She sped up, her whole body began bouncing on the bull as he began thrusting hard in turn. She his thick pole, its girth stretching her large but tight pussy. Inches appeared and disappeared of his throbbing meat, the thick sheath around the base of his penis was soaked in their juices. Sarahs ample breasts bounced with every thrust, eliciting increasing sprays of sweet milk from the engorging mammaries as they slapped up and down. Dean's huge pendulous balls slapping her butt as he thrust his hips in turn, lifting her body with his immense strength, burrowing his cock into hereto unexplored depths.

Sarah felt the fullness of him fill her with every thrust. She craved it, the throbbing heat of his shaft buried deep inside of her. His thick meat rubbed her clit, as waves of squelching hot fluids spurting out her with every thrust. She felt herself getting close, her walls pulling and prying at the massive column of meat extending out of the bulls crotch. Waves of euphoria spread from deep insider her, from her leaking nipples to the tips of her long soft ears. Electricity arced through her body as she felt everything in her body tense. Her vagina pried harder and harder at the bulls erection as her already throbbing nipples pushed out increasingly voluminous columns of milk onto the bulls chest and face. She bit her lip with her large buck teeth as she arching her back. Throwing her head back, she grabbed big handfuls of his thick chest fur as she felt it coming. Her breasts heaving into the air as she edged infinitesimally closer.

Splashes of the rabbits milked coated his thick muzzle, his huge tongue lapping it off of his face. Each taste of the sweet white nectar seemed to drive his libido even higher. The heat inside him felt like molten lava, it coursed through his veins, through his muscles and concentrated in his heavy crotch. At that moment Dean didn't feel like a man or a giant bull, he just felt purpose, and that purpose was singular, to serve his cocks throbbing desire. He was slave to its desire and it desired to be put into the deeper and harder into the rabbit. He obeyed as he thrust harder and faster, his powerful heart was racing, he could feel it in his big cow ears. Dean felt his big balls tighten as he got closer. He could feel his seed roiling up his column, its already substantial girth and length flaring even larger as his thick urethra was quickly filled with hot cum.

He gripped her hips tighter with his large thick hoof hands as he began to cum. He pulled her completely onto his shaft, her thick lips pushing up against his crotch tightly as thick ropes of his bull cum pushed deep into her. Wave after wave cascaded into her cervix and beyond. He gritted his broad teeth as he unloaded into her, his balls convulsing and shuddering as they were all too willing to unload everything they had. His flat tipped cock sealing in his seed as best it could. "Muauuuuuuuuuuuwwwwhhhhhhh" he bellowed loudly as he continued to cum over and over. Deans whole body thrusting deeply into the rabbit.

Sarah was coming as well, her body perfectly timed with the bucking bull below her. She released his chest fur as she felt her walls spasm violently, dumping lubricants into her love channel to mix with the scalding hot spurts of cum from the bull. "Immmm commmmminnnnngggg" she moaned as she grabbed handfuls of her breasts forcing more milk out of her heaving jugs. Her whole body spasmed as she felt herself get deliciously filled over and over. Dean wasn't as big as James but he was at least as powerful. She was pressed hard up against the bull as they rode their orgasms together. Her pussy overflowing with their combined love juices as they squeaked, mooed and moaned through the electricity coursing through their bodies.
