Even as the years pass, their desire remains undiminished... Satsuki, a married woman overwhelmed by pent-up longing, and Riri Koda, a passionate woman in her fifties—both driven by intense lust. Unable to endure her sexless marriage any longer, Satsuki is seduced by Riri into a world of forbidden pleasure. Their lips entwine, fingers explore, leading to an intimate union between women.
