The Soldier and the Wolf

When soldier John Wood is invalided out, he doesn't have much to live for- but when he finds a stray dog during a rainstorm, he can't help but take it in. Unbeknownst to him, this dog has a secret: he's actually a wolf shifter, and he's determined to show John just how grateful he is! Warning: this 8100 word short story contains wolf shifters, hurt/comfort, 69ing and explicit oral and anal sex!
