Carrie sneaked off to get a male costume. She knew she'd agreed to get a female costume, but she wanted John to know how sex on the other side was like. Hopefully, she'd be able to convince him to forgive her, but she knew John would enjoy what she had planned in the end. She finally found a costume she liked, a two tailed fox, much like Tails himself from the Sonic games, except older. She grabbed the costume, and bolted for the changing room with a pair of breasts before John could spot what exactly Carrie had picked. Carrie stripped, and put on the costume, with the breasts, and then covered up with her clothes. The breasts morphed the costume into a feminine shape, but hadn't gotten rid of the penis. The clothes hid that bit of appendage. Carrie came out, looking every bit the beautiful vixen she appeared to have chosen.
"Alright! Let's get going now!" Carrie said, quickly pulling John with her out of the building before she could take the penis with her. Just like a cartoon character, John's struggle to stay made her stretch, leaving part of her where she wanted to be, and the rest of her with Carrie who was by now already out of the door. John gave up and hung limp after his body parts slingshot back to him, just letting Carrie toonishly drag him to their next destination
