"I haven't had many sexual partners, so I probably haven't had an orgasm yet."Minami Masaki, 30 years old. She is a married woman who works as an office worker and has been married for five years. Her current husband is her fourth sexual partner, and the previous three were boyfriends she dated in junior high school, high school, and college. "When you don't have much experience with each other, you don't know if you're good or bad. I feel relieved if the other person feels good." Minami says she was hooked on pleasing her partner by trying out what she learned from watching adult videos. In fact, she has a stronger Kokoro about sex and an interest in adult videos than most people. "I want to know the limits of how good I can feel, so I'd like to cum today."
