It seemed like it took hours to go back to sleep. It wasn’t until I was settled did I realize my butt was bumping against my sister who had gotten under the covers too. Sex I went over the top and started spewing a second load into her. As her butt crunched my balls her eyes flew wide and she gasped “Oh!” Watching and hearing her reaction pumped me up even more so I did it again. “What the hell?” I turned to Tina, “There’s only one bed.” She peered around me to look at the sleeping arrangements. I tried not to look at her but I caught a glimpse of her firm round butt and long shapely legs while she had her back to me. Her tits were soft and warm on my skin, her stomach and thighs pleasantly pressing me into the bed. As I built up the courage to open a new line of talk, I could feel my nuts pulling up tight and my prick filling with hot blood.
