My step-sister had her friend over at the house for a huge party. I was in the kitchen making something to eat when I had seen them walk in from the living room. I knew her friend had wanted to fuck me ever since we met but I had never acted on it. Tonight must have been my lucky night because it really surprised me when they BOTH dropped to their knees and started pleasuring me. I took turns fucking them both until we almost got caught, and then we went upstairs to my step-sisters room and then finished me off.
