Mule Slap
Similar to a "Donkey Punch" but done during oral sex. While receiving oral sex from your partner slap your thighs together as hard as you can with their head right in between them. Make it count and try and do it right before you orgasm for that "little extra" as they clench up around your genitals. Best done while laying down on your back and your feet flat on the bed or surface you are laying on to give you optimal slapping power.
"I was going down on my girlfriend last night and she totally mule slapped me right when she was about to cum and made my ears ring."
