Hayao Imagawa, a 30 year old salary man, has lost any hope to find a girlfriend. That’s why he spends his nights close to Momoko-chan, one of those rubber kind of women, to keep him busy.
One of those nights when he is getting inspired, someone whispers a harsh warning right on his ear: ‘At this rate, you’ll die a virgin‘. That’s probably something that Hayao already thought, but being told that at your place, in the dark and by a naked guy, that surprises Hayao more than anything.
The naked guy is named Daigorou, he is a ‘God of Sex’, who gets rid of Momoko-chan right away. Now with no air at all, Hayao starts screaming asking for an explanation.
After many tries, Daigorou is able to tell Hayao that heaven has sent him just to help with this crude reality that is virginity. Hayao is not convinced at all, and Daigorou tries to be clear with him in so many ways.
In the end, the lessons have begun, and Daigorou starts explaining Hayao the importance of being soft and tender when the right girl comes into his life. Of course, a guy with all that hidden lust starts dreaming out loud, even at work.
After a long day, Hayao returns home, just ot be dragged into Daigorou’s insanity. There is no way he can return to his old self, and Hayao must face reality, he needs to find a girlfriend and also get rid of this annoying God of Sex.
