Secret Therapist

Shino is the owner of a brothel that offers women a therapy service. Wanting to show that he can treat men as well as women, he participates in a television show and meets a young actor named Izuki.

A few days later, Shino has a meeting with a masked client in a hotel and he realizes that he is none other than Izuki! Using all his know-how, Shino discovers that the young actor is a premature ejaculator and tells him that he will let him ejaculate as long as he wants to make him feel better. Izuki, who wants to appear seductive but is actually rather naive, finds himself falling prey to Shino's sweet words. This is how a gentle therapy begins between the charismatic Izuki and the handsome therapist Shino!
