I saw this image on deviant art and fell in love with it (Here is the artist: http://pudgeysabertooth.deviantart.com/ ), and I hadn't posted a story in a long while so I thought, why not? If you find any gramatical errors be sure to tell me in the comments, same for if you have a suggetion. Thanks!
Hope you enjoy :)
