Hey, darling. I was just out shopping for some new lingerie that I think you'll really like. No, I wasn't planning on cooking dinner. Why don't you make yourself something to drink and meet me in the bedroom? I promise It'll be worth your while.
Before I show you my first new set of lingerie, we're going to make sure you don't get the wrong idea about what's going to happen. Since sex night isn't for another few days, I'm going to put your thingy in this cute widdle chastity device. That's a good boy. Now try not to get too hard while step-Mommy models her sexy new floral bra and and panties for you. You might hurt yourself.
I also spent your money on a stunning rhinestone bodysuit fit for a pop-star. This one also seems to make your chastity cage tighter. Well now your widdle stiffy is going to be out of site and out of mind, because I'm going to put it in an adorable diaper! Don't fuss, baby, and step-Mommy will show you the last of the pwetty outfits you bought her today.
This shiny black bra and panty set makes me feel so sexy. How do you feel in your diaper? Hopefully a widdle embarrassed and very submissive. Your life is going to be all about step-Mommy's pleasure from now on. Starting with you watching me masturbate with my expensive new glass dildo! Good boy.
