Jon splashed down at the bottom and quickly got up to see who came with him. Zoe stood up out of the water, and gasped when she saw a completely flat, boyish chest with two small, dark nipples on her topless body. Jon looked down and saw Zoe's modest breasts and bikini top stuck on his body. They looked a little silly, especially since he still had his relatively broad shoulders and masculine face.
Before Zoe could say anything, Jon said "Listen, Zoe, you have to swap back with Amanda. If you do that, I'll swap back with you so you can get these back."
Zoe looked pissed off, but she agreed. They trudged back to the top of the slide, and Jon asked the man if Zoe should ride down with him or with Amanda first.
The man made a shaky smile, and said, "Well, I don't suppose it matters much, but the slide will only swap back the last thing it did. If you ride down with someone else, then any earlier changes are permanent. Well, unless you get lucky, I suppose.
Amanda screamed, and said "That's it, you'll hear from my lawyer, assholes!" as she hopped on the slide and went down alone.
"Wait!" yelled the attendant, "You shouldn't go by yourself.... well, that was a bad choice."
