Mai and Ena are elite female mahjong players whose talent has made them famous and earned them countless enemies. Invited to an underground casino match where every 1,000 points costs one milliliter of aphrodisiac, a single drop clouds their judgment and sends them to a crushing defeat. Taken to another room, they are drugged and raped, penetrated vaginally and anally at once, then creampied in their gaping asses. Their pride breaks as their bodies convulse through helpless orgasms, and the once-regal champions end up reduced to third-rate spectacle players who draw crowds by exposing themselves.
