An internal health examination held at a company in Tokyo. The doctor in charge of the examination obsessively targeted big-breasted female employees, touching their nipples during examinations and engaging in despicable acts. These acts were secretly recorded as masturbation videos and are now presented in a carefully selected collection. The footage captures how these accomplished career women were drugged and rendered unconscious, then sexually exploited without consent. The videos clearly show the doctor using a speculum to open the vagina and performing creampie after creampie deep into the uterus.
