Somewhere in Tokyo, the organizers have prepared a top-floor suite. It's a secret circle where housewives who yearn to drink the semen of men other than their husbands gather nightly. Tonight, eight men and women, unable to be satisfied by the ordinary, have come to the event. All prying is forbidden; they can simply forget about reality, surrender to a whirlpool of pleasure, and record and share everything they experience in this special space.
