Suckosis is a real medical condition in the DSM (Dick Suck Manual). It can involve teeth, but it's not a prerequisite criterion. It's characterized by blowing done with a relentless and single-minded obsession to gluck-gluck the shaft and worship the balls. Nothing can stand between a woman in a deep suckosis and what she needs most: that sticky, wet nut eruption down her pretty little throat. It's often accompanying other conditions, such as Extreme Intra-Vaginal Contraction (See: Gorilla Grip Puss-Puss).
