Chastity for a long time.

Naughty, naughty, naughty boy. I told you not to pleasure yourself.

And what are you going to do as soon as I take this off of you?

Seriously? I'm going to be locked up for good.

That's that. That's it! Don't even make a face.

You're trained not to do that. Do you want me to punish you some more?
