Every man dream
I read a manga about this exact thing. Whenever this boy puts on a swimsuit, he’ll turn into a female until he takes it off, and then he’ll turn back male. His sister will grow a penis, whenever she wears male swim trunks. I remember them experimenting with different suits, because depending on the suit, it could make his breast bigger or smaller. I don’t recall the name of the manga

He..well guess she might like what’s under that suit when it comes off
