Yuna has had a smooth life growing up and is famous for her beauty at university. When she is invited by a friend from college to go out for drinks, she is told that the female friend she was supposed to be with suddenly canceled the meeting. The toast is short-lived, but a sleeping pill is added to Yuna's drink and she falls asleep. Her men fuck her as much as they like while she sleeps, and cum inside her. After that, she is made to drink an aphrodisiac, and when Yuna wakes up, she loses her reason and is swallowed up by sexual desire.
