Mayuka Ohara undergoes a gynecological examination as part of her company's health checkup, one that wasn't covered in the standard procedure. Awaiting her is the fate of female employees at SOD—lewd examination items piling on one after another. Measurements of her areolas and genital area, meticulous breast palpation, and fluid tests taken directly from her genitals—all conducted in an intensely erotic atmosphere. Through SOD's signature explicit interrogation method, Mayuka's body is completely exposed and scrutinized as if entirely naked.
