Sorry for the non-explicitness, I originally drew Fang and Claw here back when I’d first gotten into pokemorphing and was still keeping them clean.  
The Annapuma and Unipuma of my various Pokemorph stories, the Pooch Sisters are the mischievious muscle who typically torment my various good guys, typically Poke-Man or Evan and Fargo. While they aren’t stupid, they ARE prone to acting on feral instinct instead of any forethought, which is why they are typically paired with a more logical partner, such as Romero to Houndour or Buzwhirrclick the Magnemite…of course, between vamping the hapless males or using them as chew-toys, they still typically end up getting their own way, which is part of why they aren’t considered more of a threat.  
I love these girls…so why haven’t I drawn more porn with them, anyway?
