double chocolate fountain
When you're hitting your girl from behind in the behind after a day of munching on bratwurst and cans of bushes baked beans. When suddenly she erupts shart all around the circumference of your cock, a wide spray much to your dismay. The pressure of this eruption has forced the cabbage scented diarrhea down your own ureth. Naturally, the only thing left to do is pull your wang-dang out, and stroke out the rest of the rancid fecal juice onto her back, and not neglecting to get some spritzes in her hair for karma's sake. Thus erecting the double chocolate fountain.
After we left the BBQ, Jenny and I had a double chocolate fountain for dessert.
