Yoshinaga Yo is a 53-year-old housewife. She is married for 25 years and is the mother of two children. She has only had four relationships with men, including her husband, but has only cheated on one man in the past. Her partner is a man two years older than her who shares her hobby of karaoke classes. "I used to be relatively indifferent to sex, but this man is what you would call a 'sexual freak' for his age. I was shocked at how energetic he was in bed, like he was a different person." After experiencing vaginal orgasm for the first time, her interest in pleasure increased all at once, and her body became unsatisfied with ordinary sex with her husband. The naked and disheveled appearance of this late-blooming wife in her 25th year of marriage is just too inappropriate!
