A ritual of adulthood that persists to this day in Y City, Mountain Prefecture, is a misguided ceremony. The content involves the daughters of the clan offering their virginity to elder relatives in an act of incestuous intercourse.

She was even made to drink aphrodisiacs, losing her self-control, drooling as she straddled her father and was made to grind her hips.
