Kyoko Hanamiya and big-titted newcomer Ruka Itoi headline this lavish collaboration set in a notorious underground brothel apartment in Osaka's Minami district.

Newcomers and regulars alike surrender their minds and balls as the pair tease, dominate, and drain them until they are completely spent.
