You stare at yourself, horrified. How is this even possible?? You are unable to move anything. As you stare at your reflection, you slowly slide back into the wolf's sheath, enclosing you in darkness, warmth, and a musky stench. You feel yourself jiggle slightly as your host walks off into the forest.
Sometime later (you can't really tell time while enclosed in a sheath), you feel yourself stiffen. Light blinds you as you emerge from your sheath. You aren't fully stiff, however, and find yourself staring at the grass on the forest floor. A pressure rises from the back of your "throat" until a yellow, salty liquid jets out of your mouth. It tastes awful, but there's nothing you can do to shut the flow off. After what seems like forever, the stream of urine slows to a dribble. Your host sits on his haunches and immediately proceeds to lick your cock face, making it difficult to see but also removing much of the acrid taste of urine. The stroking of his tongue against your body causes you to stiffen slightly. Then the wolf stands up again and resumes trotting, leaving you to slide back into his warm dark folds.
It's almost impossible to comprehend that you are nothing but a body part to this wolf now, to be used for sex and pissing. You might have cried if you still had tear ducts.
