The billiards hall "Sayama Billiards," run by the legendary hustler "King Sayama," was once wildly popular. But business has declined, and Sayama is desperate. Only two unruly female customers keep coming in—"Yumi Kazama" and "Naho Hazuki." Frustrated by their behavior, Sayama turns to his ex-wife, Ryouko, and decides to host a mixed-gender tournament. On the day of the event, voluptuous milf beauties in tight outfits gather at the hall. The fierce competition is about to begin.
