I absolutely love this. Martha teasing the Doctor is hilarious. This fic is incredible you got the character's spot on, that's exactly the way a scene like this would have gone. The Doctor is hopeless he can't see that Martha is teasing him and he's making it worse by not having a clue that she is poking fun at him. The licking fetish so spot on and it is so like Martha to tease him about that, even more when she discovers that, licking is a fetish of his, and when he's embarrassed. The TARDIS talking to Martha is just fantastically awesome. It really goes to show that whatever the TARDIS says goes.
