Whip reward
BDSM idea by Magnuz Binder.
You're fighting to hold your orgasm back, but in vain. The strong little bullet vibrator taped directly to your clit works it magic despite your efforts and you cum, pulling and squirming violently in your bonds. But your orgasm is cut short by your promised reward for it, as I bury the slim whip into your breast, hitting square across your already welted nipple, sending it into agony. I let the whip rest lightly on your other, also welted nipple, waiting for your next orgasm, to deliver your next reward.
