It Was Always Your Choice
OK, pet. Just so you understand that this was always, always your choice, I'm going to let you do something you haven't done in a long, long while. Stroke yourself, not by command, but in any way, shape or form you want. Use whatever toys you want. There's only one thing that I have command over, the thing I've always had command over, and that is your ability to cum. Drive yourself to the edge as often as you like, but don't strain yourself, because you know your last orgasm before that final lock-up is mine. You gave it to me when you agreed to this whole teasing game in the first place, and again when you moved in as my permanent pet, and a third time when you ordered the device. Only I can tell you when to come.
But you know you don't want it any other way.
There's one other rule, and this one is very important. If I tell you to get soft, you will do it. I know how hard it is for you, and I know you think you know what comes next. You've read those teases online, the ones where the man is asked to get soft only to hear the devastating *click* *snap* of the lock closing on his manhood forever. But that's exactly why I'm going to ask you to do it, and why when you do do it you will be ready to place that lubed-up device on your soft little member. Because then you'll never be sure if that last orgasm is going to happen after all. And because then you will show me that you are ready to give that orgasm up just to be my chastity slave.
