Fascinated by my aunt...

``Three months have passed since I started living at Aunt Erika's house to attend medical school in Tokyo. Before I knew it, it was summer vacation and I was stuck at home every day, busy with assignments.One day, my aunt came to my room and asked my mother. That night, I couldn't sleep well and went to the bathroom. When I passed by my aunt and uncle's bedroom, I heard her lewd voice. When I looked inside, I saw her writhing in a different way than usual."
