My sister was staying with me while she was home on vacation. Me, her, my friend and his wife went out to a club and when we went to leave we had a flat. It was really cold and my friend and I changed the tire while the car was running so the women wouldn’t be cold. My sister and I were in the backseat and when I got back in the car I touched my sister with my ice cold hands, she jumped and then took them and put them between her legs saying let me warm them up. She on jeans but my right hand was literally in her crotch and I jokingly rubbed it with my little finger, she adjusted and pushed my hand tighter.
We were driving along with my right hand still between her legs in full masturbation. I did it until we were dropped off. When we got in the house my sister asked me if I wanted to finish it. We had sex that night and again in the morning. I never felt guilt about it, I think because we are adults and she asked me, well, she asked the first time, in the morning it was my ideal. lol.
