Tony has been an out of shape 16 year old guy that couldn't get a girlfriend no matter how hard he tried. This drove him to do perverted this such as going to the lingerie section of stores as messing with bras and panties. He was hit with the transformation and was now a naked human-dog like being. He was still chubby like he was when he was fully human, but he noticed his penis now retracted inside him like a sheath. But that sheath was coming out, because he was still thinking about sex.
He noticed other shoppers had gone through transformations as well. Most were struggling in their clothes. Then his perverted mind hit him. If this happened to everyone, then there had to be transformed women in dressing room, possibly without clothing getting in the way! He took off toward the dressing rooms and snuck into the biggest one at the end. And there was Tracy. Still stunned by the transformation, she doesn't even notice Tony.
Tony looks her over. Tony was never a boob guy, but was somewhat upset that she no longer had a pair. But that ass. Tony was always an ass guy and was happen to see that transformed girls still had full female human asses. He decided to make his move.
Tracy didn't noticed Tony until Tony came in an snapped her thong off with his teeth. She attempted to escape, but Tony had her pinned. Tony's penis had now left its sheath. Besides the sheath, his penis was just like always was, human and not that big. But Tony was able to get in Tracy's vagina, not located in her crack. Tracy couldn't believe she was being rapped by this fat human-dog thing, but that was soon lost as pleasure hit her. This didn't last long as Tony was a virgin and obviously wasn't use to sex. So when he came he came quick and unlike human sex, he felt his penis knot up inside Tracy. Tracy tried to escaped, but knew soon it was no use.
Then she thought, "Oh my God, what if I'm pregnant! And I wonder if were pretty much dogs, if it will be one baby or a litter of them!" She wanted to scream, but all she could do was whine.
