You have been such a good boy for step-Mommy. You got your grades up, you've been helping me with chores around the house, (sometimes without me even having to ask!), and I am just so proud of you and so happy with you. I know I promised you a reward if you did the things I asked, and now I'm here to give you that reward. It's ok, I've seen you looking at me, and I know you've been trying to sneak a peak at me when getting out of the shower. This will just be our little secret, just keep it between us. And if you can keep being a good boy for step-Mommny and you keep up with your chores, and keep those grades up, next time maybe I can use my mouth or something else. I'm very curious to know how your big cock would feel elsewhere.
