We are roommates and good friends. I have a really close relationship with my step-mom and I hang out with her all the time. You don't have a good relationship with your own step-mom so you feel awkward anytime I mention mine. I get home from going out to lunch with my step-mom and notice you're once again acting strange. I confront you about how every time I mention my step-mom, you get obviously uncomfortable. You try to brush it off but I keep pestering you until you admit to me that you have step-mommy issues. I feel so bad for you! step-Moms are supposed to be caring and loving, it makes me so sad that you didn't have that! I offer to give you a bit of role-play therapy and say that I would be happy to act as your step-mom for today and treat you the way a step-mother is supposed to treat her step-son! You decline but I insist. I know it'll make you feel better. We lay down together and I tell you all kinds of sweet and loving things that a step-mom would say to her step-son. I tell you how much I love you and how I would do anything to make you happy. We do this for a little while until I notice you have a boner. At first I laugh and tease you about getting hard for your step-mom, but then I explain that step-moms live to take care of their step-sons. And I start giving you a handjob (off camera). I keep up the step-mommy talk because it's obvious you really enjoy it... I give you blowjob and then offer to really take care of you, AND that cock. I strip off my clothes and turn around. I slowly start riding you in reverse cowgirl, then I turn round and ride you until I cum (full body POV). I beg for you to cum for step-mommy and fill up the pussy you came from. You're such a good boy for step-Mommy, aren't you?
