My Step-Sis is a Slut. Oops, I fucked my step-sister!. My step-sis wanted to know if I had a big dick... Well, she sure found out when I put my 10'' up her tiny little ass and pussy!. I caught my step-sister having fun with the pool stream. Her small cunt needed a big dick so we played doctor right there in the family pool!. My step-sis was watching TV half-naked in the living room. She was so hot that I fucked her on the parent's couch....
