Kokoro, a female college student who loves to drink, is drinking non-stop at her usual club drinking party. Her junior, Takeshi, who's drinking with her, gets drunk and falls asleep, missing the last bus. Seeing Takeshi's confusion, Kokoro suggests spending the night in her room. On the way to Kokoro's room, knowing Takeshi is a virgin, and feeling sexually frustrated, Kokoro seduces him. However… she ends up being repeatedly brought to orgasm by his exaggerated energy.
