The series documents the escalating sexual rivalry between the busty Paizuri Cheerleading club and the beefy Sakunyuu Ouendan. Their feud is settled not on the sports field, but through a series of erotic competitions centered on their respective specialties. The cheerleaders, led by their stacked captain, leverage their massive, sensitive tits for intense paizuri, sliding dicks between their oiled-up breasts until their opponents erupt in pleasure. In response, the muscular Ouendan squad showcases their sakunyuu prowess, aggressively milking the cheerleaders' huge udders, suckling and pumping their nipples until they gush streams of milk in ecstatic defeat. Each episode escalates the stakes, introducing new techniques and more extreme scenarios. The competitions range from one-on-one paizuri duels to group milking orgies, with the narrative focusing on the raw, uninhibited lust and the climactic moments where one team's sexual skill overpowers the other, resulting in cum-drenched victories and milk-soaked submissions.
