You felt your legs get weaker as his tail slithered behind you and wrapped around your lower body, before entering your back. You felt a sudden sharp pain as it penetrated your skin but after a while, the pain became a strange feeling that can't be described. You felt something being inserted into you from the tail. After a while, you felt something changing and your vision getting blurry. Once you regained your senses, you were now a monster. A creature far more powerful than any human. Not to mention, you were much cuter.
