A Through Milking
Now slut, you're going to produce a sample for me. Don't you dare get excited. We've ensured that it'll be acquired in a way that isn't very pleasant for you at all. It goes without saying that the thought of a full orgasm will not even cross your mind.
We need to make your cock head as tender as possible for this to work properly, so take a very thin rubber band. Snap your tightly bound cock head through the thin latex of the condom a brutal 15 times. Make each one feel like you couldn't bare to take the next. Snap it all over, the tip, the tender underside, the little lips, everywhere slut.
Upon finishing your snaps, remove the band from your cock head and place the vibrator down hard as high as it goes on your cock head. Do not hesitate whore, we need you as overwhelmed as humanly possible. The second you feel an orgasm approaching, pull the vibe away and leak.
I doubt you'll last more than a few seconds...
