Some parts I couldn't understand but theres the gist: High school couple where the girlfriend is clearly dominant. She gets better grades, is better at sports, etc... She was humiliated by her boyfriend by being seen in the page 3 costume by her classmates. Blames the guy. To make amends, she forces him to wear a bodysuit and share the same humiliation she felt. He puts on the suit and to his surprise his voice changes and he can feel every sensation on his skin. Girlfriend explains to him that her father is a Nobel prize winner in chemistry and she had his laboratories help to make the suit. She then proceeds to play around with his new body until he's overwhelmed by pleasure. When he wakes up he's in the aforementioned cosplay costume and to his surprise his girlfriend is wearing a suit that has transformed her body into his former self. They go to town until she is driven crazy by pleasure and asks to be raped. Concludes with him asking how long he'll be trapped in her body. She says that it's usually one day, but in his case he has to wait until graduation in three weeks.
