My stepsister made me cum by sitting wildly on my dick.

We were confined at home due to the high cases of Covid in our region, my parents were always very afraid. That's why it was increasingly difficult to find time with Shauna to relieve ourselves of our lust. Shauna then had a brilliant idea, saying that we would do a Netflix session of animated films, as our parents obviously don't like them. With that we managed to have some private time and she knew how to take advantage, she soon sat on my dick and made me cum twice in a row as well as cumming a lot on my dick.
