A hugely popular series in the FANZA doujin manga section, "My Tokyo Sex Life," is made into a live-action film with Ran Kikuno, a tall, big-breasted woman who exudes the allure of a seductive adult! Hamanei, a man who is troubled by such a strange symptom that he suddenly gets hard anywhere, anytime. It interferes with his daily life, and he decides to visit the hospital. At the doctor's instruction, he is asked to "submit his semen" for examination... But he can't come out because of the unfamiliar situation and tension. "…No good, it won't come out at all…" His head goes blank with anxiety and shame, and finally he exhausts himself and falls asleep on the bed. "Are you okay?" When he wakes up to a gentle voice, standing there is a super beautiful nurse with huge breasts that seem to spill out from the gap in her white coat. "If you don't mind… shall I help you?" One word was said with a soft smile. The next moment, Hamanei's heartbeat jumps up. The heartbeat and breathing echoing in the examination room―― Is this treatment, or is it temptation? An unstoppable erection, an irresistible impulse. The forbidden medical chart woven by a man with an 'erectile constitution' and a 'big-breasted nurse' is now opened――.
