Yuna, a popular beauty who has lived a charmed life and is well-known at university, gets invited to a drinking party by her classmates. When they arrive, they're told their female friend bailed last minute. Before they can even raise a toast, she's drugged and falls asleep. The guys take advantage of her unconscious state, relentlessly fucking and creampieing her. Later, she's given aphrodisiacs, and when she wakes up, her inhibitions are gone, and she's consumed by lust.
