Drinking party with close male friends from university... drunk and unable to refuse, they just keep having sex. "Eh, aren't we all friends!?" Some have feelings for Kana. Others just want to have sex with her. The alcohol gets going... and the guys take turns having sex with Kana. Drunk and secretly having sex with one guy... they all pounce on him... and take turns inserting! This isn't rape! It's a sport of sex with consent! (lol).
