Hello, My step-son!
It sound strange to hear Me calling you like this? Well, you know, I've married your step-father, so you are now, officially, My step-son and I'm your Step-Mother.
I wish we will have a nice and loving relationship, so we will be a happy familly! Therefore, you will have to do as I want, in order to please Me. If I am happy, your step-dad will be happy and keep paying your bills and this is mean you'll be happy too!
Now, let's put the cards on the table: I know you are one of those weird, perverse, feet lover! I saw you sniffing My shoes and My stocking while masturbating! How disgusting ...hahaha ...you don't know how lucky you are because I love handsome young men like you and I love having a good foot massage!
So, here is what I expect from you: you will worship and adore My feet, any time I demand it!
Your dick will be lock in chastity device and I'll hold the key and you will have an ejaculation only with My approval.
If you manage to make Me happy, you will be rewarded. I don't accept a negative answer and I don't accept disobedience! From now I will rule this house, I will rule your life and your sexuality!
These being said, kneel and begin sniffing and kissing My feet! My feet are so perfect, so you should be grateful that your Step-mother let you indulge your pathetic fetish!
