I (a high school student) living in Tokyo used to be a truant. To refresh myself, I spent the summer vacation alone at my relative's house in the countryside. There, I met my cousin Miho, who is ten years older than me, and she jokingly said, 'Want to just stick it in a little?' Taking her seriously, I couldn't hold back my desire and ended up having sex with her every day, ejaculating inside.
