「You should do it too, big sister. It feels really good, sex.」 I have stepsisters from my father's remarriage. Their names are Miharu and Shion. One weekend, when our parents went out and left the house, my relationship with my sisters changed dramatically. In front of my older sister Miharu, I had a physical relationship with my younger sister Shion, and then also had sex with Miharu. And for the three days our parents were away, we just enjoyed sex.
