26-year-old young wife Risa appears quiet and serious. She married early and is now in her sixth year of marriage. Her ideal pace is once a week. However, she's grown accustomed to her husband's quickness and can no longer achieve satisfaction. Although she relieves herself through masturbation, she feels limited and seeks new excitement. Risa loves sex and is so sensitive that she gets wet just from holding hands. The moment she's touched, she switches on, transforming into a completely different, lustful woman who reaches climax over and over. Her passion and desire know no bounds—an insatiable young wife without end.
