I tore my girlfriend's leggings to fuck her doggy style in her pussy

When my cute stepsister MilaSolana does yoga in my room, I always get a hard-on for her delicious figure and ass. Well, today the girl asks me to help her, and I’m trying to drill the hole between her legs as best I can to get laid. Having lubricated what I can with massage oil, I insert my end between the girl’s buns, and then she takes the initiative into her own hands... and not just her hands!
