Stepmommy has a new rule for you, because you might be in college, but I'm still your step-parent. I remember college and your college experience is NOT going to be about slutting around, or getting someone pregnant. You are going to study, and that's that. Now let's put on your chastity cage. Your dick can be such a distraction for you, getting you into trouble, making you do things you normally wouldn't do. We'll keep it all locked up under my key so you can focus on your classes like a responsible boy.
