In Shikiyoku INFINITE, the Yarima family women—Mitsuko (mother), Sayoko (second daughter), and Kurumi (third daughter)—are extreme nymphomaniacs taking full advantage of the absent father. Mitsuko and Sayoko routinely bring home men for unrestrained orgies and creampie sessions. Despite her initial resistance, Kurumi succumbs to her inherited "slut genes," seducing her hired tutor during a biology lesson turned hands-on sex education. In "Yarima Delivery," a deliveryman arrives to find naked Kurumi and walks into Mitsuko's ongoing gangbang party, leading to his inevitable participation. "Yarima Taxi" follows a driver picking up a sexy mother-daughter pair fresh from a party; their escalating in-car masturbation and seduction pull him into a roadside frenzy. These stories highlight relentless female desire, incestuous family dynamics, group sex, and public/indoor debauchery, all rendered with fluid animation and explicit detail. Perfect for fans of hardcore harem, MILF, and taboo themes.
