Rina initiates a video call with her ex-husband and her son, Shota, while wearing a revealing bikini. Encouraged by her new partner, Kenya, she decides to show off for her former family. Rina explicitly teases them by masturbating on camera. She then proceeds to perform oral sex on Kenya while her ex-husband and son watch. The video call eventually concludes with a "To Be Continued..." message.
