In order to take the university entrance exam in Tokyo, I decided to stay with my uncle who lives in the city for a while. His wife, Yuu san, is a career woman who graduated from a prestigious university, a cool and sophisticated woman who is not found in the countryside where I live. However, she was cold towards me and always forced me to do chores. One day, while cleaning the bath, I turned on Yuu shower and saw her bra and her large breasts, which made me feel embarrassed. She mischievously leaned in close and asked me, "Are you a virgin?"
