It just makes you harder inside of that belt, doesn't it? You're being treated like a naughty boy and you like it. The girls of CBT will be well prepared to administer plenty of punishments to you, slave boy, but trust me when I say that you'd better not deserve it when it comes. Of course, no matter what the circumstances, you'll always deserve it. Remember that.
I want you to try a little harder now. Don't damage yourself, but definitely up the ante a bit, OK? Twenty times, this time.
Now forty. Remember that you deserve it.
