Unable to conceive, Usui and his wife decide to undergo fertility treatment. After counseling, Satomi makes her husband wait in a separate room and receives a palpation of the female genitalia. A doctor excited by a married woman with outstanding sensitivity who reacts to mere palpation secretly inserts her male genitalia and pours her semen into the vagina. And on the next examination day, when she is stimulated more radically than last time, Satomi finally gets hooked and transforms into a horny unfaithful wife who enjoys thrilling NTR play even though her husband is right next to her.
