It was a hot, sweltering summer day. My sister and my sister spend time when their parents are away. The air conditioner was broken, the room was too hot, I wore a loose shirt to my chest, my skin was damp. I succumbed to Mia's temptation to show off her breasts and want to do it. In the bathroom, in the hallway, blowing work in the kitchen, brushing fingers, etc. Because of the heat, I kept hitting my little ass many times... Memories of summer with my sister.
