After all this talk of pain... I think we should start with pleasure. I've never seen a man in pleasure before, so show me. Show me how you would stroke that thing if it were up to you. While you strip naked, I will state the obvious. You will NEVER orgasm without my express permission. If you ever feel an orgasm start to come on you will remove all stimulation and ruin it. You want to know what the punishment is for spurting out that stuff without my say so? I can tell you now that I will make you remember your failure for a long long time, boy.
Get on your knees and stroke it, now.
