A camera-loving service-industry manager in his forties meets Yua, a voluptuous married woman, through her secret social-media account. She posts lewd photos behind her husband's back and craves attention, so he persuades her to visit his home for a private shoot. He carefully films her enormous breasts, huge ass, and thick body in a series of fetish poses. Being watched through the lens excites her far beyond expectations, drawing out the shameless sexual side her husband has never seen and leading to her first homemade sex video and repeated orgasms.
