I’m here to teach you darling on how to be a very good boy for me. And the best way we can ensure your obedience is by keeping your hormones in check. Step-Mommy is always has your best interests at heart and by locking you up in chastity will show your commitment to me. Let’s face it you don’t have a large enough cock for Step-Mommy or any woman for that matter. Only big boys are allowed to be free. I’ll keep your key close to my chest at all times darling and make sure you are behaving like good boy should. Large cocks are allowed to be around me and masturbate over porn, and by locking your cock up will make sure you never leave Step-Mommy, won’t it darling?
