Your nerdy girlfriend Stella arrives wearing her tight new jeans to show off her round ass for you. She knows how much you love her ass, so she shakes it around and spanks it just to tease you! As she strips them off, she thinks you're just wanting a closer look... but what she doesn't know is that you have always wanted to bury your face right in her ass and take a big sniff! She's surprised when you tell her this, but it totally turns her on and she starts masturbating while you jack off to her smelly butthole.
