Leftover Pie
When your girl is riding you and you cum inside of her and she cums at the same time. You then stay in that position for 5 minutes until you are limp. Then and only then do you pull out and let the juices seep over your coffee table and into your anal cavity. Realizing you have nothing to wipe it with, you wait 30 minutes to reach home, also realizing that your means of transportation is the same means that you have had intercourse inside. When you arrive at your destination, go straight into the bathroom and take off your boxers, hold it up to the light, and you will notice a wet line from the tip of the iceberg to the end of your tail; Leftover Pie.
Man, I had to wait a whole 30 minutes to smell my leftover pie.
