Leon entered into the room looking normal, thankfully for Jake. "What's up Rexy? You've been cooped here since classes ended?" Leon asked. "Uh... Yeah. Nothing going on round these parts" Jake said nervously. "You gotta get out of the dorm on your free time sometimes man. Whole world waiting for ya out there. No need to be shy about the dino look." Leon turned around to close the door. When Leon turned to close the door, Jake noticed that Leon's legs were looking thicker. Not only his legs, but his butt was swelling right in front of his eyes. Jake's tail started thumping on the ground to try and calm his nerves.
"I get it. Your different. But you should embrace it. It's actually kind of cool having a t-rex for a room- oh..." Leon started to feel pressure in his groin. Jake started sweating. "Ugh... Did I eat something funny or something... Wait... It's getting... Bigger?" Leon than looked at his legs. "Wait... Everything looks bigger. Hold on." Leon went to unbutton his pants. Jake tried to stop him. "Whoa! Hold on! Not in the room dude!" Jake protested. "This could be a serious medical issue. Just look away. I don't care if you see my junk." Leon continued to zip his pants down. He noticed his crotch area was bulging out from under his underwear.
"Heh. Could use some more bulk down there- wait... It's pink!" Jake and Leon were wide eyed staring at the bulge in his underwear. Without haste, Leon uncovered his crotch to see a pink bulge of flesh above his dick. "What the hell?" Leon's thought was interrupted with his legs going through another growth spurt. One that burst his pants. "Jesus! What's with this?!" He looked to see his legs were reforming into digitigrade legs as his knees pushed lower into his calves and pushed forward. His toenails were also turning black and spreading around his feet, completely covering his toes into round flat hooves. While his hooves were forming, a lump from the base of his spine started forming, growing longer until it made a slim tail with a black haired tassel at the end.
"Jake... What the mooOOOoo is going-" Leon slapped his hands together after hearing his voice. Not long after his fingernails started turning black and wrapping around his tips. "Did that come out of meeoOOoo?" The second moo sent Leon's face pushing forward, flaring his nostrils outward, turning it into a bovine snout. Another moo came out of his mouth, enlongating his nose, and stretching and pointing his ears as they twitched uncontrollably.
Leon again felt pressure in his groin. "Ohh... Down there again?" He and Jake watched as his bulge grew bigger and spread wider until it was bunched up between his legs. The bulge started protruding lumps with holes in them. Leon's udder was complete along with his change. Leon dropped to his knees, feeling the udder grow even bigger. "Oh god, what the MOOOOO!!!" Leon let out a loud moo as milk started pouring out from his udder. The milk splashed Jake in the face and all over the room.
Jake wiped his face off with his shirt, and shot milk out his snout. He looked at Leon, now panting rubbing his pulsating udder. Jake had to find a way to explain things to Leon and fast.
