Tyler saw that while caught up in his lust, Madame Illusia had spun the wheel for him once more. She smiled gleefully as the wheel slowed. Tyler watched the needle stop on the section that read "Dog".
"Down you go Tyler! Down like the dog you are!" Madame Illusia proclaimed. Tyler fell forward onto his hands, and heard something snap. He tried to get back up, but his hips wouldn't let him. To his horror, he realized that he was quadrupedal now. And he looked down to watch his hands become paws.
His palms grew thick callous like lumps, that then turned into black pads. His fingers shortened as claws broke through his nails. His thumbs pulled back into dew claws. Tyler felt a familiar prickling sensation was fur grew from his sweaty pores. The fur was the same color as that on his horse legs. But this fur was much longer, and thicker. Like a dog's should be.
Tyler felt balls smack against his horse legs. His penis quickly slid from his sheath, and rub against Tyler's torso. He whimpered like a dog when he realized that he wouldn't be able to stroke himself ever again. Not with paws, and not since he was stuck on all fours.
He bent his head down and saw his horsecock's dripping hole staring back at him. Tyler needed to do something about how hard it was. With every change, it was like his body was beginning for more. But this time Tyler couldn't do anything to help himself.
