Ruined for step-M0mmy

Sweetie, you LOVE listening to Me guide your stroking sessions. I know you're a good boy and you wait all week long just for step-M0mmy to tell you how to do it. You are so obedient, so submissive, so weak for step-M0mmy, and you love it that way. Well, honey, step-M0mmy loves it, too! I love knowing how deeply devoted you are to Me, how I'm on your mind all day every day, and to keep it that way, I've got a special ending to our stroke session today. Don't worry! You still get to cum, and I'm not locking you in chastity. It's just something special, and guaranteed to keep you nice and submissive for Me.
