Kisaragi-sensei no Sakusei Chiryou!

Yuu Satou, a 19-year-old who recently broke up with his girlfriend due to erectile dysfunction, visits a men's clinic. There, he meets Dr. Kisaragi, who diagnoses him with psychogenic ED and offers a special "milking treatment" to help him recover. Yuu Satou continues his treatment with Dr. Kisaragi. She performs oral sex on him, swallowing his semen. On the third day of treatment, she exposes her breasts and performs a paizuri (breast sex) on him, leading to another ejaculation. On the fourth day, she masturbates him while exposing her crotch, and he ejaculates on her face and body. Dr. Kisaragi continues Yuu's treatment, engaging in vaginal intercourse in various positions. After multiple rounds, she changes into a revealing bunny-like outfit for the next phase of treatment. Yuu and Dr. Kisaragi continue their intense sexual encounter. Kisaragi, wearing a revealing bunny outfit, rides Yuu and takes him in various positions, including missionary and doggy style. They engage in passionate kissing and deep penetration, with Yuu ejaculating inside her multiple times. Kisaragi also performs fellatio on Yuu, deep-throating him until he cums in her mouth. The session is filled with intense pleasure and exhaustion for both. Yuu Satou reaches his limit and ejaculates inside Dr. Kisaragi while she is wearing a bunny outfit. Later, he visits her office again, explaining that his ED is cured but he now has the opposite problem, being constantly aroused and thinking about her. Kisaragi then suggests starting a 'semen extraction treatment'.
