After the sports festival, the popular women of Class 3-A gather in their classroom for an adult school role-play after-party with snacks and drinks. The festive mood loosens their inhibitions, their dirty talk turns into lesbian play, and a male classmate secretly watches. When they catch him, they pounce on his cock instead of scolding him, taking turns until everyone is naked and the room becomes a full-blown orgy. Knowing this may be his only chance with the class's hottest women, he fucks them with everything he has, without condoms, filling them with creampies until they pass out from exhaustion.
