My timing couldn't have been worse.

I opened the door to the apartment I shared with my muscle bound beefcake of a roommate Max, just as his massive tool spurted its gallons of zebra cum directly at me. It was like the most clichéd thing that could have happened to start this whole mess. But clichés have some reason to exist, as much as I hate them

"Gotcha," he rumbled, pointing his fire hose to make sure he covered every inch of me in his cream, and soaking the entire wall and floor in front of him.

"Holy shit, what the fuck man?" I sputtered, trying to wipe the warm, salty, sticky mess out of my face. Had you looked at me then, you would have never thought I was a human, unlike like my roommate. Maybe a weird white goo monster arising from the depths to attack a city in a cheesy monster film.

"Like, come on man, that's not..." I started, before gagging on some of the goop that entered my mouth. The cum began to soak into my skin, making my entire body heat up, my heart race, aches and pains settling into my muscles and bones. It was... weird. It hurt, but it was nice; it was disgusting but pleasurable. My entire body tingled, and it felt weird as suddenly my nose and mouth stretched forward into a muzzle, my ears grew larger and went to the top of my head, and the bones in my legs cracked and reformed, my toe nails growing larger and covering my entire foot in a shiny black hoof.

"Are you turning me into a fucking zebra?" I cried out as white and black fur began to grow out of my arms, and a pain on my lower back suddenly burst into a long, ropey tail. I could feel my crotch swell up as well, my average human cock now taking on a more equine size and shape.

"Oh, so much more than that," Max grinned, his massive cock finally stopped spurting cum, now just leaking everywhere.

I took a deep breath to berate him some more, even though the air was more musk and sex than anything that could be called fresh. But as I breathed in, it felt like all the air was staying inside me, turning me into a balloon. My shoulders grew bigger and more rounded, my biceps and triceps gained more mass, ripping the sleeves of my t-shirt to make room. My chest puffed out, my abs popped out one by one, forming the foundation of an eight pack, only the bottom two showed to the world as my shirt rode up. My claves and legs bulged out with newfound power, the tight jeans barely able to hold back the growing mass. And my groin was burning up, giving me a painful hard on in my jeans.

"What the fuck did you doOOOOO-!" I cried out, as my entire body exploded with muscle and mass. The little bit of a growth that I had before was just the start, a little steam coming off a pot before it reached a roaring boil.

"Going to make you sexy," Max purred, grinning as he watched my distress.

My shirt was shredded as my pecs, arms, neck and shoulders all simultaneously burst out larger, competing for space on my small frame. My body decided that that wasn't acceptable, and just increased my bone structure to hold even more beef. My muzzle was propped up by my massive pecs, so large that it would be impossible to look over them again. My back grew bigger to support it all, but it forced my arms outwards, the muscle unwilling or unable to let them hang against my side.

The jeans I was wearing vanished into a flurry of denim shreds, the zipper mangled beyond repair, the button now imbedded deep into a wall from the force of the sudden growth. My legs and hooves grew larger and bulkier, forcing them into a permanent sumo wrestler stance to give enough room for my calves, enough to support the sheer mass that had become my body. It was all topped off, crowned more like, by a perfectly rounded, firm and perky bubble butt, which was impossible to not flaunt if every move I made. I could hear the floor below me groan and scream from the sudden increase in weight, from one muscle bound zebra to two.

But it was my cock that got the most attention. The average human sized cock was just a distant memory, and even the average equine member I had for a couple minutes was quickly fading away. My meat stick doubled, tripled in length, gushing pre-seed like a faucet to add to the milky mess made by Max that formed a pond around our hooves. I groaned as my balls grew heftier and weightier, turning into massive cum factories like the pair that Max had sprayed me with, pulling down and swinging low, forcing my legs even wider apart. I reached down to grab my new cock, my hands unable to reach around the thick pole to stroke, adding more pre to the mess on the floor.

Max rumbled over, each footstep shaking the foundations of the house, before reaching out to grope my shot glass sized nipples and basketball sized biceps. "Man, you're looking good now," he snorted, bending over and licking some of his cum that was stuck on my neck.

That tongue made me shudder, thrusting my hips forward and launching a huge spurt of pre across the room, soaking the side of the couch in front of me.

Max grinned, reaching a beefy hand behind my head and pulling me to his muzzle, and a wet, sloppy, muscle jock kiss ensued, our tongues wrestling with each other to enter the other's mouth. Max tweaked my nipple again, while I let one hand off my cock to flex my new, powerful arms, feeling the strength and power rushing through my body. his other hand reached to fondle my balls, the huge orbs overfilling his hands, sloshing as more and more zebra cum was made. Fuck, this was awesome.

Max finally pulled away, with a glimmer of lust in his eyes and a goofy grin on his face. "Why don't we give that thing a test run?" he asked, grabbing and squeezing my cock. I let out a bellow of ecstasy, and he barely had time to turn around before the flared head of my dick was pushed up against this perfect ass, probing for that sweet spot.

Since it's not exactly easy shoving a something into a hole when you can't see it, I pushed Max down, flopping him over the edge of the couch, allowing me to admire his rear end for all of three seconds before I crammed my equine log into his tight tailhole. Max cried out, his cock spraying more pre from his flared tip. My thick length, using my own pre as lube, easily slipped deep into the man that made changed me. It was like shoving a log into a pencil sharpener with how tight he was, but fuck if I was going to pay him back for this.

"Oh, fuck yeah," Max groaned, out as I pushed in another half a foot of my cock. "I knew you would - oooooo - be great addition."

"What?" I snorted, reached up and grabbing his back, before thrusting my hips forward.

Max was about to answer, but my thrusts, slamming up against his prostate, must have distracted him. "You know those - fuck that's deep - those guys like me? Huge and sexy zebras? Always hanging out together in the gym?"

I rammed my cock balls deep in his ass, making him squeal like a little pony. "Those jocks?" I pulled out half way, before slamming in again. "I thought you were all just..." I grunted, digging my hands as deep as I could into his fur, trying to find a handle on those mountains of rock hard muscle that covered his entire body.

"Working out? FuuuuUUUUCK THAT!" Max cried out as I hilted him again, and again, making him whinny and moan, his ass clenching even tighter around my pole. I bit my lip, trying to not scream like him.

Max got a moment to catch his breath as I rocked my hips, making my shaft piston in and out of his well-abused hole. "By the time we lift weights, we are so fucking horny we just start screwing each other." He grabbed hold of the couch, rocking his ass back to take in my cock as I pushed forward. "All this is just because of the best fucking gay sex orgy you will ever see!"

The thought of a bunch of other guys, all zebras, muscled up and well hung, all getting it on in a pile of fur and sweat and muscle and cock and cum...

"FUCK!" I cried out as I imagined myself in the middle, slamming my hips into Max's ass again, and piledriving his rear as fast as my new body could handle. Max was withering and groaning, his cock constantly pouring out so much pre seed that barrels of oil couldn't handle all the man juices around my hooves.

"Hell ya!" Max said, sweat dripping from every inch of his body. "Fuck me! Fill me up!"

"I'm...gonna..."

"Do it!"

I tossed my head back and brayed as loud as my lungs could muster, and my cock spewed all its bounty into Max's butt. Max also came again, the sticky, white-hot flood of spunk washing over my hooves and flooding our apartment in his mess and musk and sex.

I had no idea when I finally stopped shooting loads into his rear. It could have been minutes or days for all I cared at that point. When I finally did pull out, a waterfall of cum followed, adding to the mess around us. We looked at each other, an almost perfect mirror reflection of muscle bound, sweat drenched, hyper endowed, sexed-up zebras.

And then it was my turn to be pounded. Then Max again, then me. Back and forth all night.

And I couldn't wait to find a scrawny guy to change into another muscle zebra.
