40-year-old Sayumi Horita. An F-cup woman with a bright, cheerful personality and a soft, gentle aura. In the interview, Sayumi comes across as lively and friendly, answering openly and warmly. However, her relationship with her husband has grown stale, and they're currently in a sexless marriage. Although she loves sex and masturbation, she feels unsatisfied and has been struggling with pent-up sexual frustration. Her joyful, candid expressions throughout are incredibly cute and captivating. When touched intimately, her body proves highly sensitive and easily orgasmic—she reaches climax repeatedly, squirting copious amounts of fluid each time from sheer pleasure. Sayumi's smiling, enthusiastic enjoyment all the way to the end makes her a truly delightful presence to watch.
