(n.) a surprise technique used by a woman being fucked from behind. The woman buries her face in a pepper covered pillow to make herself sneeze at the same time her man starts to cum. The sneeze will cause her vaginal muscles to grip his ejacualting dick like the airway-constricting hug from fat Aunt Martha little boys try to hide from at family reunions.
My wife’s Sneaky Aunt Martha hugged my dick so tight, I was gasping for air when I busted a nut.
