Kazumi, a big-breasted married woman suffering from infertility, becomes the target of a corrupt doctor under the guise of fertility treatment. Sensitive and aroused due to being premenstrual, her intimate area becomes wet and increasingly responsive to daily stimulation with fingers and medical devices. The doctors exploit her vulnerable state, gradually luring her into lewd acts until eventually they penetrate her with their erect cocks and creampie her. This malicious exploitation depicts how she is physically and mentally dominated under the false pretense of infertility treatment.
