When I was 26, my fam rented a house at the shore. Me, sister, and step bro stayed in the same room for a few nights. I was on the floor and it was hurting me. So in the middle of the night, I asked my step bro to slide over so I could get in. At the time step bro was 18. I should say we had all drank a bit the previous night. So some decisions might not have been thought through.
When I got in bed, I said I was cold, so we kinda snuggled. I could feel him starting to get hard. It grew and I could feel it between my ass cheeks. Soooo I started a slow grind. And he did too. We grinded for several mins. It was building. Both panting. Grinding. Harder. I then heard him breath short breaths. I could feel him cumming. Made me cum too.
We stayed there the rest of the night. Never spoke of it. That was 25 years ago. I think about it often.
