32-year-old Miho no Sanjo, a mother of one, has a natural inclination to cater to men. However, her accommodating nature seems to have backfired, as her once-manly husband has become increasingly demanding, turning their intimate moments into a king-like play. This realization that she's not his servant has grown within her, intensifying her desire for infidelity, an experience she's never had. "It's embarrassing to say this... but I'm an M-type and crave being dominated," she admits. Her pent-up sexual desire and suppressed abnormal desires are about to unlock the immoral door within this beautiful, innocent-looking wife.
