During a company trip party, a drunken coworker sexually harasses the narrator's fiancée, Sumire. When he lashes out, the company president threatens to fire him and orders Sumire to liven up the party if they want forgiveness. The harassment escalates into chopsticks clenched between her buttocks, naked dancing, an obscene legs-spread party game, and walking around with a vibrator fixed in place. Humiliated in front of her fiancé, Sumire arouses the men until they rape her like animals throughout the night.
