"No matter how good a couple's relationship is, there are some things you can't do with your husband," says Kaede Kikuta, 46, a full-time housewife. She is married for 22 years this year and is the mother of two children. Kaede still has sex with her husband twice a week, but she says she has cheated on him a few times in the past. "Sex with my husband is great, but in the past it has become a ritual to maintain our relationship...I can't feel the heat rising up inside me like I used to, and the feeling of wondering what will happen to me, unless I'm with someone else." Before she knew it, a "rape desire" had begun to grow within her. Every time she went to a hotel with a man she met on a dating site, she would enjoy the thrill in Kokoro, thinking, "Today, I'm going to be messed up by a dangerous person." However, everyone she had met so far had only been kind. Today, she will be experiencing sex with two different types of actors, yin and yang, light and dark, and both extremes!
