"Not cool man! Not cool!" yelped Julius as the last shreds of clothing fell from his ursine body.
"You got what you deserved" smiled Cody, his mouth expanding into a muzzle. He crouched and ripped off the remnants of his clothing. "You'll get to like being a bear. I know I do." He reached down and rubbed his now exposed crotch. "Let your beast out."
"N-No, no!" roared Julius, staring with shame and horror at his once slim body, now fat and covered in white fur. "You can't do this to me!"
"I already have. Take a look in the mirror."
Julius turned his head and saw a large white man-bear reflected back at him. He groaned.
"Cheer up Jules" said Cody. "Look, Calvin's joining us too." Calvin had taken the precaution of stripping beforehand, and walked naked across the room to the chips and dip bowls. He dipped a chip and ate it, rubbing his belly with his hand. "Mmmmmm Cody, this dip sure tastes good. You should cum in all our food from now on!" He laughed as his body inflated and furred over, and yawned to show off his growing canines and snout. With a clawed soon-to-be paw he reached over and rubbed Cody's bear cock.
"Does that make you horny Julius?" he asked.
Julius leaned against the wall and slid down in defeat. "I'm straight" he whimpered.
"Too bad, 'cause we're gonna have fun with you anyway!" With that the two brown bears sprang on top of the white bear, who weighed less than them, and Calvin pinned Julius down while Cody stuck his cock in the latter's mouth.
"I jizzed in the dip while I was in human form. Let's see what'll happen to you when you taste me after I've transformed!"
With one hand Cody held Julius's head as it bobbed up and down on his cock, while with the other he massaged Julius's reluctant dick to calm him. In a few minutes Cody hit orgasm and began pumping his semen into Julius's mouth. He pumped so much that Julius began choking on the pearly goo, and the two brown bears released him. Julius swallowed the cum and staggered across the room, collapsing onto the floor. He gasped as he felt his body start to change yet again...
