36-year-old beauty and married woman Rei, unable to endure over half a year without her husband due to his work transfer, finds herself overwhelmed by pent-up desire when surrounded by men—her erotic switch instantly flipped. Wearing sheer, sexy lingerie that heightens her arousal, she flaunts her fully unleashed lust. Her nipples become rock-hard, and with every wave of pleasure, she moans, "My nipples feel so good..." Unable to contain her cravings, her desires erupt as she performs an exhibitionistic masturbation, dripping with abundant lubrication, climaxing repeatedly through intense toy play.
