When you are anally doing a female, and sneakily squeeze your PENOR (penis) out of her rectum, continuously grunt as if you are still giving it to her...then you take HER puppies penis and put it in her rectum, still grunting as if it's yours.
Then you scream "WOOF!", and run out the door naked...
Estimated Time :32 seconds if puppy is nearby.
"Man, I so totally used puppy play to ditch that fat chick last night."
