Keep the pecker in the pooper.
From Create Your Own Story
You keep fucking the Nazi general in the ass - you can't take it anymore - you blast a few loads of sperm in the general's anus.
Eventually the general shits on your dick - you pull your pecker out only to find it covered in sperm, blood and shit.
You pull up your pants, fouling them in the process.
The general runs at you - you realize you must use the environment to your advantage in order to defeat him.
