Nico, a cosplayer, is captured by the fearsome group "Crazy Penis," who thoroughly train cute boys to teach them what it means to be a real slut. After being restrained, she is teased by the group, who thoroughly train her sensitive micro body, leaving her with a constant erection. To top it off, she is injected with a powerful aphrodisiac, and her anus is transformed into one that can cum in the ass again and again. Nico goes crazy when her rock-hard cock is tormented with a TE○GA drill and her ass pussy is stuffed with a powerful massage gun weapon.
