Kaoru Hirayama, with her fair skin and voluptuous bust, visits the hospital due to abdominal pain, but an unexpected turn of events occurs during the doctor's examination when her breasts are groped. A hospital technician, exuding erotic energy, meticulously applies oil from her breasts to her nipples as preparation for an X-ray, continuing to massage and fondle her large tits. Ultimately, citing a deficiency in male hormones, she is subjected to extreme stimulation as the doctor penetrates her vagina with his penis like an injection. Throughout the process, Kaoru embraces her deeply masochistic desires, fully revealing her allure as a lustful married woman.
