Mizuka (Suika), a money-hungry gyaru with enormous breasts, tries to earn quick cash by showing off her assets in what she calls “tit work.” Her encounter with an obsessive, big-breast-loving old man quickly escalates from simple flashing to rough breast groping and deep paizuri. Overwhelmed by the intense stimulation, her body betrays her as she falls into ecstasy.

In the second episode, the same perverted man, who mysteriously knows personal details about Mizuka, tricks her innocent older sister Momone (Hundred Sound) by pretending to be a friend. Invited into their home, he aggressively targets Momone’s massive breasts, introducing her to overwhelming pleasure she has never experienced. The once-pure sister melts under his skilled paizuri and sexual advances, agreeing to meet him again while completely addicted.

Based on Obui’s “Paihame Kazoku” doujin series and animated by STUDIO竜M’s, this OVA focuses heavily on huge breasts, titfucking, and the gradual corruption of a busty family by lust-driven older men. Expect raw, breast-centric hentai action with little plot beyond escalating sexual domination.
