more or less, girlfriend gets the skinsuit for the boyfriend. He wears it around. He has some female masturbation session. When the experiment is meant to end, his girlfriend sprays him with the suit remover. It doesn't work because while wearing the suit you may become stuck if you have sexual actions that lead to climax. This is because technically you have both sexual organs. Therefor when he came as a woman he also came as a man an self fertilized. LOL. Not sure if he can turn back after the birth, seems like he can't, but either way the last little bit seems to be a separate story with the same guy. The two wish that she could have his dick and she gets his dick, he becomes a woman. Again gets pregnant. Not sure though. All from google translate, so take it with a grain of sand.
