Kakeru, who suffers from premature ejaculation, and his girlfriend Maki, who is frigid, find a clinic that can solve their problems. Although they feel a little suspicious, they decide to go as a couple to improve their sex life for each other's sake. The two are led to separate rooms. Kakeru's doctor, Serizawa, is a somewhat seductive woman with large breasts. The treatment begins with teasing handjobs to get him used to the stimulation, followed by deep, slow fellatio… He reacts nervously, and his masochistic nature is revealed, so with each visit, he is toyed with and repeatedly ejaculates. "Aren't you curious about what Maki-sama is doing?" While Kakeru is being pathetically made to cum repeatedly… Maki is being seduced and cheated on by a burly male doctor who is developing all of her erogenous zones…! From the hugely popular circle 'Shirasudon', whose other works also boast overwhelming sales figures, comes a twisted form of love, a new kind of masochistic NTR where depravity and regret intertwine, and it's incredibly arousing…!
