Kakeru, who struggles with finishing too fast, and his girlfriend Maki, who struggles to finish at all, find a clinic that promises to solve both. Something about it feels slightly off, but for each other's sake they decide to attend as a couple. They're shown to separate rooms. Kakeru's doctor, Serizawa, is a bewitching, busty older woman. The treatment starts immediately: edging handjobs to get him used to stimulation, thick slow blowjobs — he twitches and responds, and once his masochistic streak is exposed, every visit becomes another round of being toyed with and going off early. “Aren't you curious what Maki is doing?” While Kakeru is being made to cum pathetically over and over, Maki is having every erogenous zone opened up by a hulking male doctor, and taken from him. A warped shape of love from “Shirasudon,” the hugely popular circle whose other titles sell in overwhelming numbers — a new kind of masochistic-orgasm NTR that genuinely works.
