Chad zoned out at his desk. His cock tenting his pants was uncomfortable, but showed no sign of relenting. He bit his lip, and closed his eyes. Suddenly, the pain was gone, and he could feel his bare buttocks against a cold surface. He opened his eyes, and looked down his clothing was gone. He looked up the classroom was gone. He was in some sort of cage. Three walls were corrugated metal, as was the roof, and the fourth side was a chain link gate. His cock throbbed. He looked down at it. It wasn't his cock - well, it was, but it was different now. A red triangular pointy cock emerged from his increasingly hairier sheath.
"Ha ha, it worked. Well, Chad, you cost me big, now's your chance to make it back for me, and if you do, you'll earn your humanity again. If not?" shrugged Rico, a punk-ass classmate wearing only a muscle shirt, torn blue jeans and boots, he continued, "Well, if not, I guess, I drop you off at the animal shelter, where they will cut your balls off, and if no one adopts you in 30 days, well, you get to find out if all dogs do go to heaven."
Chad growled.
"That's the spirit, jock boy! Get good and mean. Your stupid 100 yard run won your team the championship, but cost me $4800 in winnings. Now you're going to be my entry for dog fighting contests. You got added motivation to kill the other dogs or at least defeat them, you want to be a real boy again," snarled Rico waking the metal kennel with a stick.
Chad tried to shout, but he could only manage barks.
"Okay, boy, you've shown your teeth, you look hilarious, oh, I should be vidding this!" Rico said pulling a phone out of his back pocket. He began filming, as Chad continued to change into a big dog.
Chad realized he was now standing on all fours, and his feet and hands were now paws. He jumped up on the chain link gate and made the whole kennel rattle.
"Yeah, work out your anger, but remember, Chad, I own you now, so don't even think of biting me or guess who's never going to be human again? You gotta obey me, if you want to be human again," Rico explained. He pulled a pair of soiled yellow briefs out of his jeans, and shoved them through the cage opening, saying, "Here get used to the smell. I wore them for two weeks to get them really ripe. This is the scent of your master, memorize it, and obey, and maybe we'll even be buddies after you win me twenty grand."
Chad stopped barking, and then barked twice.
"Oh, good boy, you have been listening and you still understand me. Wasn't sure if you'd completely dog out or not? Yeah, you cost me $4800, but turning you into a dog, and back again is not cheap, plus I got expenses dog food, entry fees, time spent training you, and I need to make a profit, so I figure once you've earned me $20,000 in winnings - after expenses- I will turn you back. Got it?"
Chad barked, and then dropped back from the gate he had been leaning his paws on, and whimpered softly.
"Glad we came to an understanding."
Rico turned off the phone, put it in his pocket, and walked away. Chad stared at the dirty underwear on the floor of his kennel. He sniffed them. Rico! Master? He grabbed the underwear in his teeth, growled and shook them violently. Rico left him until the next day. Chad relieved himself in the corner a couple of times. Then he curled up with the well-chewed underwear as his pillow and went to sleep.
