Haruki is a normal guy with normal grades and looks, a twin sister and of course still a virgin. However, one thing that set him apart from others is his vibrator fetish. Of course, it’s not something that he would tell others, so he has kept it a secret for over 10 years. At his school, there are two girls out of his league: the beautiful and smart honor student Fumika who is respected by all, and the cute and lively Natsuya, who most guys want as their girlfriend. For some reason, they have vibrators under their panties and the remotes are in his hands!? Moreover, it wasn’t just to satisfy his fetish, but it’s also the key to solving the girls’ problems?
