Step Son Fills Up Mommy's Ass

Decided to have a quick cardio session and hop in the shower to rinse off. While I was showering my stepson had a question and saw he was nervous seeing me in the shower. I know hes been looking at me and since his dad was gone, I figured maybe we should have a little fun. I knew he wanted it soon as I saw his massive cock in his pants. I gave him the special treatment and let him stuff my tight asshole before leaving me with a delicious creampie.
