Tiffany noticed something was wrong when she began growning hair all along her body. She lifted up her hands but stared in horror as it changed into a paw. Soon she became a Labrator retriver.
Tiffany's room changed into a storage closet with a doggy bed lying in the center.
She pushed herself off of Kyle and ran down the hall. She had to find a computer and try to fix this. She got into the kitchen before running into a pair of feminine legs. She nervously glance up and saw Amy staring down at her with her arms crossed.
"So, 'sis'," she grinned, "Try to steal my boyfriend, huh? Well, now you get your punishment! You want to act like a dog in heat, that's what your going to be!"
She turned and saw Kyle staring at her. "Amy, what's going on?"
"And you tried to cheat on me? Well, I'm going to make sure that you never leave me again. Your change should start soon."
Kyle suddenly felt a weird feeling through his body. He shrank and disappeared in his clothes. Tiffany watched as Amy pulled off the dress she was wearing, leaving her only in her bra and panties. She hesitated, then smiled at Tiffany. "What do I have to feel embarresed about? You're just a dog now." She pulled off her underwear and reached inside of Kyle's clothes and pulled out a cream-colored bra and panty set. She pulled them on, feeling a wave of ectasy wash over her.
"Oh my gosh!" she grinned, "This is like having an orgasim every second! I need sex, now!"
