Focused on her task at hand, and on wiggling out of those constricting bonds, the girl was far too occupied to notice anything amiss, not even the goblin using her disgustingly from afar.  It was hard for her to do her job properly, the goblin stank to high heaven besides the fact that she didn't really want to be doing this.  Wait, of course she did.  Didn't she?  Yes, she did...it was a favor...for a friend.  That's right, that was it.  A favor for a friend.
