"Her huge tits shake a lot when she cheers," says Itsukaichi, a second-year female manager who is rumored to be cute and busty even at other schools. "If she becomes a regular, she can have sex," "She's dating the captain," "She gave the advisor a blowjob," and other sexy rumors are endless because she's so Ke'ai. But Itsukaichi comes to a boys' dormitory where women are not allowed... Romance is prohibited, she is devoted to club activities, and the boys' dormitory is full of physical monsters, sweaty and smells of shampoo, and the members, who can't even masturbate properly, get fully erect just from that smell, and of course there are no condoms... A creampie orgy between the boys from the sports club with no limits on physical strength and stamina and the busty manager!
