Description
It was Summer, my sister and I came home the sun was already rising after a full night partying with friends. We didn't drink that much but we've made a lot mixtures. When we got home, my sister let the keys fell on the floor, when she bent to pick them up I could see her waist and part of her ass. I instinct was to brag her by the waist and rub my cock against her ass. I simply did it, no second thoughts at all. She didn't even tried to stop me so we ended up on the couch.
