A red-haired woman actively sucks her friend's big and thick penis

Grandmas bag was stolen on the street and she asks her grandson to give him a couple of self-defense lessons, but for some reason they make her excited. As a result, the red-haired lady herself gets into the guy’s pants and sucks his dick before jumping on the end herself and giving herself in a couple more poses. Well, now in general it’s not clear - is self-defense needed for protection or sexual attack?!
