Yumiko Sakura is 50 years old and a full-time housewife. - She has been married to her husband for 25 years and has had a second son, and has been living without any problems, but it is said that the sex life between the couple has completely cooled down. - ``It's not just that we don't have sex...my husband is just my roommate.But I guess that's what ``family'' is all about...''She has had a history of cheating. - I still can't forget the extraordinary night I went to a happening bar for the first time over 10 years ago when I was invited by a friend. - "I was scared at first, but the atmosphere, or rather the stimulation...I was so excited that I thought it was really me."I wanted to experience that excitement and pleasure again.
