A welcome drinking party for new members of a university circle active in Tokyo is held, initiated by a 20-year-old female college student who already has a boyfriend. The meeting point is the circle representative's home, where the party kicks off. However, as the alcohol begins to wear off, the atmosphere shifts and a game of King's Game starts. Initially involving simple dares like drinking shots, it quickly escalates to kissing and drinking mouth-to-mouth. Eventually, it reaches a bold stage where members are dared to perform masturbation in front of each other. One embarrassed girl heads to the bathroom, only to be suddenly dragged in by a fellow member and forced into a blowjob and cum swallow. When another member leaves to go shopping, someone takes the chance to approach a drunk female college student passed out on the futon. She gets into it, suppressing her moans as they proceed into full-on gonzo sex, leading to an intensely heated scene.
