Mizuki is banned from anything related to sex by his mother, so when he takes the subway and a molester takes an interest in him, Mizuki let them touch him as they please. One day, this man is discovered by Mizuki. The man, Shinobu, is now blackmail by Mizuki: he has to force Mizuki even more, making him dirtier or he's going to the police.
This is wow! Really good.
