I know he wants my ass! I see him looking at it all the time. Maybe I do it on purpose sometimes just to tease him. to make him want me more. He doesn't look at his girlfriend's ass the way he looks at stepmom's. I hear him jerking off at night and I know he is thinking about my big thick jiggly ass. It turns me on and gets me so wet knowing how much he wants me. I invite him into my room one night. I know it is wrong but I let him touch it and watch it jiggle until he cannot stand it anymore and he is inside of me! I keep my crotchless panties on while I let him slide in and out. When I finally take my panties off he starts stroking his cock with them while he watches me stand over him before I lower myself back down onto his cock and let him rub oil onto my ass and hotdog it for a bit before I ride him again with my shiny big ass. I let him feel my mouth wrapped around his cock for a little while until we fuck some more. I cum so hard. I want to feel his cum on my ass.
