Tom squinted to try to make out the shape of something vaguely bovine when he felt a tremendous tightness in the rear of his pants. Staggered, he looked back and was shocked to see his very ass swelling behind him, stretching them to a point of popping the very seams.
"I, I, I, I," he could only repeat while Matt watched Tom's ass grow behind him in pulses. His hips too were starting to bulge out and a growl roared form his gut. Tom doubled over, causing his belt to snap off at the strain. His jeans had started to shred to reveal his boxers at their near breaking point.
"Oh my God dude, what's, what's happening to you?" Matt asked in a panic. He tried to back away but hit the edge of his bed and fell down sitting on his ass.
Tom appeared to be trying to stop it but there was just no force he could muster to do so. Just then, something caught his throat and crawled up it like a bubble. Tom tried to keep his mouth shut, moving his hands to stop what was coming but he felt dizzy and he fell forward. His hands saved him injury, but no sooner than he was on all fours, Tom let out a breath and no sooner than his mouth was open it was out.
"Noorrooo-OOOOOO! MAAOOOOOO!" he bellowed, shocking Matt as Tom was wide eyed and nostrils flared wide. The release came from behind as well with the cow call bringing out a swell of growth that tore his pants and boxers to pieces at last. His hips cracked, "He-help m-m-m-me Matt," Tom managed to say even as the sight before his eyes was one of his face actively pushing out into a snout.
Matt was at a complete loss. Tom was trying to navigate back up to two feet desperately, managing only to turn himself around and get no further.
From behind, Matt saw how much his friend had changed. And was still changing. His cocked was leaking watery cum just as his emptied testicles were pulled into a growing feminine, though bovine looking, sex. Above that, Tom's new pisshole and puckering butthole had him looking positively inhuman.
"Oh, OO, God..." Tom struggled to clench but noxious smells eeked out of his new asshole and signaled the first of many instinctual acts. "I'm soOOOO, sooOOryy," a beleaguered Tom said before he relaxed and plops of cow shit started coming out of him, urine soon after, while his nub of a tail and a pinkish mass at his waist came in.
Matt recoiled, moving further away on his bed until he hit the way. Tom's body started to expand, in both length and weight, while his shirt gave way and hair started to shed. It was the mass at Tom's waist, that was filling and bouncing as Tom struggled with hooves growing in, that Matt put it together.
"You're turning yourself into a cow, dude," Matt yelled at Tom, mad that he had been put in this position.
Tom looked down, his head becoming heavier, and saw his hands disappearing into hard, black hooves and his snout was only getting longer. He tossed his head back, his glasses flying along with several teeth which are quickly being replaced by larger ones.
He closer to cow than man, Matt thought as fur started to sprout and drips of milk oozed from Tom's virgin teats.
"Help me," Tom managed in a series of guttered noises while a fat tongue took the place of his old. The next thing Matt heard was plops behind Tom, only adding to the already large cowpies in the small dorm. Tom's tailed swatted behind him as the small wafted around.
Matt wasn't sure what he could do to help his friend now. Of if he could... or should.
