Chopsticked tongue
BDSM idea by Magnuz Binder.
As soon as I release the two parallel chopsticks, joined at each end with rubber bands, they close on your stretched out tongue. I increase the pressure by nudging the rubber bands from the ends of the chopsticks towards the middle, until they straddle your tongue. The sharp edges digging into your tender tongue makes your original efforts to withdraw your tongue too painful to continue, and in the end, you can only stand there with your tongue clamped out of your mouth and your drool flowing generously down your chin, neck and chest.
