Hikaru, troubled by infertility, is recommended by her stepmother to undergo a uterine examination by her stepfather, an obstetrician-gynecologist.

She's trained into a wanton sex doll, experiencing uncontrollable climaxes... Under the guise of a medical examination, they create time for each other, with constant ejaculation. Is the child conceived her husband's or...?
