Description: I Diego Perez might not be the strongest or the smartest, but I know a good opportunity when I see one. My stepsister Lily Starfire is curvy in all the right places, big natural tits a fat, juicy ass. When I tell her I could use some advice in the bedroom area she basically laughs me off. But then she realizes nobody is going to help her with her math homework, then comes the pinky swear proposal. She helps me get more experience I'll tutor her in math. Opportunity, see? Well that wasn't the only thing that rose when she pulled out her big, beautiful tits. She jerked my cock off it started getting her horny! She climbed on top and slid her wet pussy on my dick, I squeezed her big boobs as she bounced up down. I fucked my stepsister hard from behind, making her big ass ripple and her pussy cum too. I couldn't help it and busted right inside her! She didn't seem pleased, but I'm going to tutor her super hard this week!
