Pull off their nipple clamps while they blow your cock

Get ready, this one is going to hurt!

While you receive a very nice blowjob from your opponent, you grab hold of their nipple clamps. You keep them in your hand for a moment, so they have time to anticipate your next move, which comes when you give them a sharp tug. The clamps are ripped off, and your opponent lets out a little gasp of pain.
