On A Friday Night During The Summer While Our Parents Were Out Of Town, My Sister And I Were Planning

On a Friday night during the summer while our parents were out of town, my sister and I were planning to go to a party. It was nearly time to leave when I entered her room while she was getting ready. “Oh sorry, sis!” I said, “thought you were done”. She replied,“I don’t mind bro, you are the most qualified to see this body, ya know. ” She hopped on the bed. “I was thinking, I don’t want to go to the party that bad… We could have more than enough fun here, just us two.. ” She began bouncing, her pretty pert breasts swaying while she looked at me with a mischievous grin. “Why don’t you hop on here with me, and I can bounce on you? ”
