Farmer O'Grady stepped out of the barn, mumbling something about needing a drink, and leaving Zack, his adopted son and farm-hand, to administer another sedative dose to the massive bull-creature that he had captured...Willis.
Willis heard the barn door close, and could sense the young man nearing him. In his hand, Zack held a large needle Farmer O'Grady had handed him. The nimble teen approached the minotaur cautiously, his eyes roaming over its massive, nude body with respect and wonder...and some sexual curiosity too as his eyes spotted the monster's huge sheath and testicles.
Opening his eyes a little, vision still blurry, Willis took in Zack's image: a tall, extremely cute, lanky teen, no older than seventeen, shirtless, with tight, farm-built tone to his tanned muscles and an oversized pair of denim overalls draped over his lithe body. Shaggy hair sandy-blond, his bare, hairless chest and dark nipples shone slightly in the dim light with sweat from his anxiousness.
Willis didn't move as Zack outstretched a hand, caressing one of his huge horns, his palm wandering down it across his neck, shoulder, and finally enormous pectoral muscle, which he squeezed. "Wow" Zack whispered, clearly in awe of the bull-man's taut definition.
Kneeling down, Zack then looked carefully at Willis, double-checking to make sure he was asleep. And, seeing no movement from the minotaur, slowly set down his syringe on the barn's hay-covered floor. "I've got a few minutes..." he murmured, assuring himself, excitement in his voice as he added, "You're amazing. I kinda wish I was what you were."
Using one hand to steady himself, Zack weighed with his other Willis' enormous balls. "Geez." he said, admiring the huge orbs, "I bet it feels awesome to have those hanging heavy between your legs. Mind you, my own are big, but damn...imagine, bull balls."
Willis couldn't help but utter a soft, bovine moan, causing Zack to fearfully withdraw his groping for a moment.
As Willis grew utterly still again, Zack once more slowly moved close to Willis, and this time began to exam his sheath. Hand far to small to hope to grip the entire thing, he instead let his fingers roam over its rough hide-like texture, a slight smile creeping over Zack's face as the monster inside began to awaken and push out. "Hot damn." he whispered, "Fuckin' huge. Dude, I'm the biggest kid in my school, and yours makes mine look like a tooth-pick. God, I bet you can suck yourself off when that thing is fully hard. I wonder if you ever do."
Willis couldn't take much more, his bullhood was swelling quickly to a full erection, causing new urges and sensations to flood his mind, and Zack's words were causing him to wriggle in both arousal and slight discomfort -- although he was certainly enjoying the boy's petting.
Snatching the boy's wrist just as Zack's finger slide across Willis massive cock's huge piss-slit, Zack suddenly went wide eyed as he realized Willis was actually awake.
Free-hand quickly trying to snatch up the sedative-filled syringe on the barn's floor, Willis moved one massive hoof and crushed it, his other powerful hand gripping Zack tight.
"Actually..." Willis said, his big eyes fully opening now to stare at Zack, a mischievous grin on his bovine muzzle that Zack couldn't quite register, "...I only recently gained...this (Willis' gaze darted to his cock). Haven't had the chance to test it yet." And, Willis gyrated his hips forward, the near erect shaft and flared head shoving themselves against Zack's exposed chest.
Standing up, Willis lifting Zack into the air, still gripping the amazed teen tightly, he spotted a quite impressive bulge under Zack's loose overalls. "Weren't kiddin' 'bout being big, were you kid." Willis rich voice tried to whisper, as he set Zack back down on the barn's floor, still holding onto him, the teen's face level with Willis' stomach and at least a foot of his thick, pulsating shaft that had risen up his chest to place its wide head between his pecs.
"No...you, you said you only recently became this way? " whispered Zack, afraid but also aroused.
"And, you said you wanted to be like me?" Willis added, a new light within his eyes, "If I make you like me, will you join me? Help me find my brother?"
Zack's jaw almost dropped, his head spinning with the offer and revelation. "Like you?" he said, mouth dry, "Uh, fuck, I'll do anything." he paused, "Wow. You have a brother?"
"Yeah..." said Willis, "He was human too, I think, at one point. Now, I don't know what he is...but he's out in the forest."
Zack nodded, "Know the forest pretty well...use to play a lot out there when I was younger. So, you can really do it, you can make me like you? I mean, a huge bull-mons...er, I guess minotaur?"
Willis could tell he had caught Zack's full attention, and gently letting the teen go from his grip, his free hand now wandering to his fully erect cock, gripping it best he could, he nodded his massive bovine head. "Yeah..." he said, a slight shiver crawling down his spine as he began to stroke his huge tool for the first time ever. "God..." he muttered under his breath, "This really is good. Hadn't done this yet..."
Zack grinned widely, "Well, before you get to far into it. Can I at least join you? Come on, change me."
Zack began to push one of his overall suspenders over his shoulder, but Willis stopped him. "Hold on." he said, "What are you doing?"
Zack looked up into the huge minotaur's face, "Well, you're going to change me, right? Into a minotaur? If I turn out to be nearly your size, I'll burst right through these clothes. Bet that'd be uncomfortable."
Willis grinned, his hand still stroking his hard cock, "Actually..." he said, "It's kinda hot. Keep the clothes on. I'll utter the spell right now."
Stepping back, Willis re-uttered the spell, as best he could from memory, and amazingly so, not missing a beat. When it came time to mention the creature to transform into, he nodded to Zack, who giddily shouted out, "MINOTAUR!"
Silence fell over the barn, and Willis leaned against the wall, his stroking increasing, his hips rutting his massive organ into his firm grip as both hands now began to slide up and down his wide shaft. Precum soaked his huge dick, and bestial sounds started to usher from his throat as he kept his gaze fixed on Zack.
Zack kept looking at himself, checking himself over, expecting the change to happen at any minute. And, finally, it did...
Zack let out a loud groan as he fell to the ground, his hands hitting the straw-covered barn's floor as he held them out to stop his fall. Looking behind him, he saw his bare feet were no longer feet at all, but fused into single lumps that was darkening into hooves. He felt his chest expanding, fur growing across his form, he let out a "AAAAAAAAAAAAAAGH!" as his horns painfully pushed through his skull, his ears elongating and shifting position.
Willis could feel himself getting closer to release as he eagerly watched Zack undergo the same transformation he had last night.
Zack felt his suspenders explode off his body as his chest reached massive proportions, his huge biceps swollen with power. The pain he had been feeling was also quickly being replaced by pleasure as his crotch area began to grow and expand. This, especially caught Zack's attention, as his already well-packed groin was now straining against his overalls, threatening to rip and unleash the truly massive giant within.
"Fuck." he said, Zack's voice rich and deep, "Oh, fuuuuuuuuck!" he bellowed, as his overall's crotch gave way just as his face was pushing out into a muzzle. Beneath Zack, a huge, veiny brown python plopped onto the ground, larger already than what Willis was stroking. And the balls at its base were nearly twice Willis' own size.
"Wow...hot." Willis said, "Guess the minotaur's attributes enhanced what you already possessed, eh ki...?" His voice wavered as he felt himself on orgasm's edge, cum boiling from his large ball's deep depths.
Zack's enormous organ folded up quickly into a new sheath, and shoving himself clumsily into a stance on his new hooves, Zack chuckled as he watched Willis body tense, knowing the other minotaur was about to shoot his seed.
"I said I was big..." Zack noted, voice now a low baritone, "And, now, I guess I really am."
Zack felt the final parts of his transformation pleasurably complete, his shredded overalls falling to the floor as his tail sprouted and his full coat came in across his dark hide.
Zack basked in his nudity, like Willis had done.
Glancing over his body admiringly, Zack turned his gaze on Willis just in time to see huge gobs of cum erupt out all over the other bull-man's chest, then the ceiling, and finally dribble across the floor in what looked like over a pint of thick, white cum.
Zack's own monster was awakening, but just as he started to reach for it, he heard Farmer O'Grady's voice, "You got that creature sedated yet, Zack?"
Leaving his swollen bull-dick alone, Zack crossed the barn and grabbed Willis by the shoulder. "Lets go..."
Smashing open a hole in the barn wall's pliable wood, Willis and Zack moved quickly through the tall grass separating the farm and nearby forest, charging full-steam towards it to escape Farmer O'Grady.
"Time to look for your brother, dude." Zack told Willis.
