There I was taking pics for Insta when I noticed you had crept into my room and was spying on me. You then try to say what I was doing was inappropriate and yet, you snuck into my room. I think the inappropriate one is you. So much so I decide to teach you a lesson. Chastity device goes on your cock for being a dirty pervert. Now try explaining why you can't have sex on Valentines Day? Somehow, I don't think you want to open that can of worms so you will just suffer knowing that your step-daughter owns your cock.
