John touched the medallion to Mandy's uniform.
"Great choice," said Amy.
Amy wasn't a bit surprised that John had chosen Mandy's clothes. She knew how much he liked sports, and every guy Amy knew enjoyed watch girls play sports for... slightly different reasons. She caught John staring at Mandy's chest and legs on a few occasions before that night. Besides Sarah, Mandy was the girl John talked about the most.
Amy watched as the medallion began to glow. As the magic took hold, John felt a strange sensation. Mandy was the same height as John and her athletic build meant that Johns body started to grow in more ways than it shrank as he slowly transformed into a copy of their athletic friend.
Amy looked at John's new body with interest. It was funny to see Mandy's face looking down at John's male clothes. "How about you put on her soccer uniform before stretching your current clothes beyond recognition?"
"Won't it be weird if I show up to a sleep over in a soccer jersey?" John almost choked on his own words. He forgot that he now possessed Mandy's voice.
"I guess that's fair, but you and Mandy are half a foot taller than me, and her breasts certainly aren't going to fit into any of my bras." As Amy spoke, she poked John on his left breast and chucked at his reaction.
"Then why offer Mandy as an option? I'll going to look like an idiot!"
"Shows what you know about girls. Sarah loves Mandy and they share clothes all the time. Tell her you didn't expect to get out of soccer practice in time and I'm sure she will loan you more than enough clothes to be comfortable for the rest of the night."
John pouted. He had a thing for Sarah and the thought of physically wearing her clothes for a night would have been enough to give John an erection, if such a thing was still possible. "Fine. Let's get this over with."
"Get his over with?" Amy asked, amused. "It's 4 pm, when do guys typically have sleepovers? How about you calm down and join me and my family for dinner first. It will give you an opportunity to learn what it is like to be Mandy before being thrown into the deep end."
