"Bison Grass" - Bison Transformation Story (Patreon)

Man into Male European Bison Transformation Story | Unwilling | NSFW | 3rd PoV | Painful

Mark never liked trying new things, but this time was different. During the parties usually were different than wherever else and so when Mark’s friend’s asked him to try out bison grass vodka – He finally agreed to.

Little did Mark know that the vodka was spiked with a transformative serum. The man unfortunately failed to notice the weird taste of it and kept drinking while the people around him chanted to continue, shot after shot. The conspirators were actually surprised that Mark lasted so long without either beginning to change or just passing out.

Until the time came for the last shot mark cheered at the audience and when he was about to drink it the glass just fallen out of his hands as they began to shudder and change. “Augh! Wh-at the hell…?” – Mark muttered staggering about and staring dimly at his fingers which started to fatten up and shorten. The entire room except for him seemed to know about what was happening, but some of them still pretended like it was a shock to see the man start to change.

Mark looked down at his belly and saw it start to swell bigger, until it visibly strained his shirt. The man scratched his head with his stubby fingers, at the same moment feeling his fingernails grow bigger. “Gu-ys, I thin-k I’m drunk, because I’m se-eing things…” – Mark groaned as now not just his belly, but his entire frame started to bloat and expand, which forced his clothing to start tear apart in places.

“Oh God Mark, you’re right! We’re calling an ambulance right on!” – Someone from the crowd shouted. Others around just stood there chuckling as subtly as possible and some of them even recorded the scene. The show was worthy of recording as Mark panted in the middle of the room as his changes began to intensify. His human body hair was turning wilder, coarser and denser. Until it fully turned into brown animalistic fur, which slowly kept spreading all over the man’s body and further straining his clothes.

Mark was too drunk to sense that he has been deceived all along. His suffering was exchanged with joy of the masses. He wanted to say something in despair, but a splitting pain in his upper skull halted him. Mark clutched his head immediately, just to feel his skin start to pound in two spots, before promptly splitting open and allowing two sharp, bony protrusion to extend. “Gh- Gh-ahhh! Guys… Don’t just stare, h-help m-eighhhh!” – He screamed in pain as the two protrusions continued to push out of his very skull. His forming horns began to curve intimidatingly as they slowly reached their final lengths. The hair Mark had on his scalp was now distinctly reformed into a clump of dense fur, from which the fur kept spreading and covering his entire head.

“You cahled thle amblhance yhet…?” – Mark lisped as his tongue went out of control and started to elongate. It’s colour changed to grey-blue. The crowd just laughed at the changing man, unable to keep pretending all of this wasn’t staged. Despite being wasted Mark started to realise that it was all their doing. Mark stared cross eyed at his nose as his facial bones began to creak and push out along with his jaws giving him a furry bovine snout. He shook his head from the discomfort and continued to watch his nose change. It began to blacken and swell larger, his nostrils flared out and his entire lower face became plumper and distinctively that of a herbivorous animal – Wet and prehensile. Lastly his ears started growing longer and more swively, just to be covered in rough fur like the rest of his head. At this point it looked as if Mark wore a very realistic bison’s mask.

Mark prodded his face with his bizarre thick nailed fingers, but it felt weird since he practically lost touch in them as they were tipped with big hoof-like nails. If not for the alcohol Mark would have panicked in a more lively manner, but in his mind he really had no idea how dire his situation was. Mark continued to stagger, especially as his feet began to stiffen and elongate, while his toes began to bundle up together and fatten into stubbier digits tipped with swollen toenails that were already turning into cloven hooves. They had yet to grow a lot and so with a few more wobbly steps Mark just came out of his shoes and his socks slid off his strange feet soon after.

The man winced as he felt jutting aches in his entire spine. He felt it thicken in waves and each time it did his body was forced to hunch over more. The worst was his upper back which bent more than anything to form the hump that bison’s have. “Ghrn… Hreellp mhreeeh…!” – Mark pleaded with a strange low voice, sounding almost like a bovine bellow. His vertebrae popped and his neck grew thicker with muscles to support his growing head’s weight.

Mark wasn’t able to withstand all this and finally collapsed onto the floor snoutfirst with a loud thud. His trousers promptly exploded in a few more places revealing more of his increasingly furry and muscular legs. The man’s spine kept throbbing, especially at his tailbone which meant only one thing. New thick vertebrae began to form and add up to the unfusing tailbone. Slowly a ropey tail wormed its way out of the man’s tattered trousers and started flailing about. The newly grown tail quickly got covered in bushy fur.

Mark slowly lifted up his body, which felt really strange as most of his body was now quadrupedal and he lacked human extremities, which were replaced with fully developed cloven hooves. His head low in shame, Mark looked around at the people around him one last time. When they saw his bovine visage they laughed out loud and so Mark didn’t ask them for help anymore, giving up hope on that.

Mark stood there on all fours, feeling his body grow bigger and taller than people around him. His torso started to crunch and broaden, which almost immediately forced his shirt to split in two and fly off his massive body. Mark’s shoulder blades creaked and expanded, locking his forelimbs in front of him, right on the ground. As the man’s torso continued to widen and expand his legs shortened a bit and became stockier, but filled with powerful muscles. The man’s ribcage popped bigger as every organ inside him ballooned out and changed more or less into a more herbivorous setup.

The man’s hips started to crack and widen too, forcing his flattening buttocks to spread and his jeans to finally tear apart entirely and fall of him, in the process exposing his puckering butthole to the audience behind him. Mark gasped when he felt something he wanted not to think about. His furry groin started to alter, but luckily his silhouette was so broad and furry that little was seen by the spectators.

Mark grunted as his genitalia began to grow bigger. His balls started to swell larger and full of potent virile bison seed. The furry scrotum’s skin began to darken and similarly did the man’s foreskin, which began to peel back and reveal an elongating pinkish shaft. Mark’s foreskin rearranged and began to envelop his lengthening cock partially, forming a fuzzy sheath which attached to his bloated belly. At its end formed a tuft of longer fur, which was another clear sign that reassured everyone around of Mark’s unchanged gender.

Mark panted exhausted of the transformation, but he still felt the growth surges. With each one the humans around him seemed more puny. The slightest of instincts that begin to build up in Mark’s head, combined with the fact those people did this to him made him furious. Mark started snorting angrily through his bigger nostrils. People around him noticed the abrupt change of his behaviour and some of them were visibly shocked if not straight up scared of what their bison turned friend would do.

Mark swayed his head as his body gained its final animalistic contours. His skull started creaking and malforming drastically, making him roar in discomfort which just scared the crowd more. His cranium flattened and forehead sloped down, his skull turned more bovine as jaws surged outwards further giving him a proper muzzle. Inside it his human teeth began to grow thicker and harder to fit his new diet habits. The brown, shaggy fur covered his entire body by now. Lastly the man’s eyes turned dark brown, which signalled the end of his transformation at last.

People around were unsure of what to do now as they haven’t planned it all out to such extent. Some of them started backing away and leaving, while others just stared at the animal in the middle of the room. Mark started scraping the floor with his right forehoof. His friend Daniel chuckled nervously and approached Mark timidly. “Listen Mark, I know you may be mad…” – He started as he stared into Mark’s furious eyes. “But… This is supposed to be temporary so chill, alright? It was all just a prank br-“ – Daniel didn’t finish as he was swiftly slammed by a powerful swing of Mark’s head and sent flying across the room.

The people in the room started screaming and began to run out of the building, leaving only Mark and Daniel inside. Daniel flew a neat distance away and hit a table, but was very much alive and so he attempted to flee from his crazed friend like the rest. Mark ran at him and pinned him to the wall. Then gestured with his head at the vodka bottle. “You’re insane! You want me to drink it?!” – Daniel asked shocked. Mark nodded and prepared to swing at Daniel with his head again. “Shit…! Okay, okay. Just calm the fuck down! I’ll drink it… It was my idea to spike it after all, I guess I… Deserve it…” – Daniel admitted, knowing that he wouldn’t leave the building with a fucking bison preventing him from that. Daniel shivered, but after a lengthy while took a sip of the vodka and slid down onto the floor waiting for his own transformation.

Whether the two of them would actually change back was uncertain, but now the two of them were in this together…
