Step-Mom Needs To Fuck Me Before Date Night With Dad

My Step-Dad has a really hot wife, Crystal, I am not sure where he met her might of been on one of those Russian mail order bride websites. She is really hot, my Step-Dad even bought her a nice pair of fake tits. I was about to jump in the shower after the gym when I accidentally walked in on her getting ready in the bathroom. Crystal invites me in, she wants to have a talk with me. I guess my Step-Dad and her are having issues, she needs some help from me. My Step-Mom tells me my Step-Dad is not satisfying her and she wants to know if I would fuck her before she went out with my Step-Dad. She doesn't wanna leave my Step-Dad and just needs a nice big dick to satisfy her, I guess I need to do this for the family.
