"Her huge tits jiggle wildly when she cheers," says Itsukaichi, a second-year female manager who is rumored to be cute and busty even at other schools. Because she's so cute, rumors about her are endless: "If you become a regular, you can have sex," "She's dating the captain," and "She used to give blowjobs to her advisor." But then Itsukaichi arrives at a boys' dormitory where women are not allowed... Romance is forbidden, she's devoted to club activities, and the dormitory is full of sweaty, stamina-boggling Itsukaichi smells of shampoo, and just the scent of it gets the club members, who can't even masturbate properly, fully erect. Naturally, there are no condoms to be found... A massive creampie orgy between the boys on the sports team with no limits on stamina or energy, and the busty manager!
