Cash-strapped adult classmates Riho and Misono take jobs together at a breast-themed hostess club. Though usually plain and overlooked, they reveal spectacular H- and J-cup breasts and eagerly serve customers with their tits. When both fall for the same customer, each secretly offers him off-menu bareback sex to win his attention. Still unsatisfied after work, they compete for his raw cock outside the club in a reverse threesome that ends with creampies.
