You fall to the floor and wrap your tail around to your front. You are overcome with the strange desire to pet and play with your own tail.
You start to pet it and it sends waves of pleasure through your body. You become oblivious to all things around you as your mind becomes completely focused on your tail. Several hours pass before you calm down enough to inspect yourself again. Your tail has become even fluffier and softer, and your arms are now covered with a coat of gray fur.
