Once you cumm inside your partner's mouth she/he will spit it up into the air. You try to catch it in your mouth then you make the choice to spit or swallow.
The act involves your erected meat stick tickling the prostate gland of a pony. This can be any pony, but the pony must be alive, and it must be conscious you sick bastard. When you have almost reached point of testicular eruption, withdraw your manhood, position yourself to the side of the pony and swing your dick so your pearly mess arcs towards the neck of the pony. The object here is to try and lasso the pony with your baby gravy. Having your sperm beam loop around the pony's neck equals success.
