The NOS button on a broad is located in the cheek. It is best activated with an open hand slap, which squeezes the cheek between the palm and teeth. It releases a shot of adrenaline and pushes the whore harder towards the finish line.

Don't confuse this with the MUTE button that is located in the vicinity of the ear and the hinge of the jaw. It is deeper in and requires a firmer strike, preferably via backhand. You need to follow through with this one and try to lead with the bottom knuckle of the middle finger.

Next weeks lesson will be Soft Meat Shots That Won't Leave A Bruise.
