Step-Son and step-mom used to fuck. Step-Son got a gf and decided he no longer wanted sex with me. But after 2 months his gf is not fucking him. He wants to fuck me again. I decide we can fuck but only on my terms. He will do what I want and be happy about it. I start taking off my clothes and telling him he can't take his clothes off or touch himself. He watches me spread my legs and bend over spreading my ass while talking dirty. He is hard but still not allowed to touch his cock. Finally I am ready to fuck and he gives it to me. He fucks me and I ride his big dick.
