We suddenly invited "Hibiki" to participate as a replacement for a missing product tester. She originally planned to bring a friend, but ended up coming alone. Since the product was targeted toward couples experiencing sexless relationships, we conducted a detailed interview about her marital sex life. She appeared highly intrigued, especially when the vibrating toys were introduced. Starting with a vibrator she'd used in her younger days, she began testing the device. Her willingness increased significantly when her payment was substantially raised, leading her to undress boldly. While she was manually stimulating herself, her pants were pulled down, revealing her erect and sensitive nipples. Though penetration was initially promised to be shallow, it quickly turned into full, deep insertion. Overcome with excitement, she ended up receiving a generous creampie.
