"Tennis, swimming, golf, billiards... I do anything that interests me," says 50-year-old Minamoto Yuki, a full-time housewife. She has been married for 25 years and lives with her husband and their university-aged son. Now that her son is safely independent and Yuki has a lot more free time, she is trying new things that she couldn't do before. However, the gap in vitality between her and her husband is growing year by year, and this is affecting the frequency of their sex... When they were younger, their sexual activity was almost daily, but before they knew it, it had dropped drastically to once a week. "Honestly, it's not enough at all... I'm only 50. I feel like I have a lot of life ahead of me, am I right?" Today, we'll be releasing that excess sexual energy to the fullest!
