My sister 'Marie' has been playing dirty games since we were kids. We would connect our penises and vaginas to play, or lick each other's genitals. One day, when I rubbed my penis against her asshole, it slipped right in. Both of us felt good and started moving our hips. From that day on, we played with her asshole every day, and eventually, her asshole became gaping wide. Here is the footage; please watch.
