Hey, step-son. You and I have to talk. I’ve noticed that you have been acting differently lately. Not in a bad way, just in a way that says you’ve grown up a little. I’m guessing that you’ve started masturbating. Don’t be embarrassed. Everybody does it. Yes, even me. I do it a lot. It feels good and it’s perfectly natural. While it is perfectly natural, we do have a bit of an issue. The reason I noticed that you’ve started masturbating is that you do it a lot. A whole lot. Whenever I pass by your room I hear you letting out quiet little moans, or you have the porn you’re watching turned up a little higher than you thought and I can hear it. The most serious thing it’s affecting is your academics. You’ve been missing school, just so you can stay home and jerk off, and now your grades are slipping. Now, there are two ways we can go about fixing this. The most severe way is for me to buy you a chastity cage and lock your cock in it. Yeah, you should look scared. That means that you will only be able to take it off if you have the key and I will be holding on to that. You will have to wear it everywhere. At school, when you go swimming with your friends. Or, you can willingly give me control of your orgasms and I will jerk you off from now on. The second option sounds much better, doesn’t it? Having step-mommy’s hands all over that big cock instead of it being locked in an embarrassing chastity cage? So, now that we’re agreed, we should start right away.
