Nao Jinguji is married and she is living happily, but her premature ejaculating husband is poor in bed and she feels unhappy. So much so that she doesn't even know what an orgasm feels like. Into this combination, the smart ass uncle noticed what was going on and decided to step in to help her with her sexual problems, without her even asking for it. She quickly realized the difference between her husband and this guy, who despite being a scumbag, was extremely talented and knew how to please her.
