When you shart and jizz at the same time.

Me and my GF just got back from Bernies Burritos and things got a little steamy in my car and in mid thrust I had a Mount Saint Helens. She then proceeded to lick my butthole.

Mount Saint Helen 

This sex act is highly contagious. It involves seducing a nun with two men. Both of these will feed the nun with cheesy gordita crunches laced with laxatives. Afterwards, the two men will pour chili down the nun's ass and proceed to ass fuck her. Soon, she will not feel good as her stomach starts to ache and this is when you should prepare for eruption. The two men lay below the nun and the nun finally let's out the biggest, bloodiest shit, erupting onto the mens' face while proceeding to announce verses from the bible. This sex act reenacts the Mt St Helen eruption in 1980. This sex act is highly encouraged as you become closer to god and understand the full capability of a volcanic eruption.

Hey man. You wouldn't believe what sister Lisa let Dan and I do. She let us try a Mount Saint Helen on her.
