Goddess Nika was shocked to notice that she had smelly feet. She, however, saw it as an opportunity as opposed to something to get her pissed off. She summoned her slave and she asked him to lick her feet and her socks. He was shocked at what she asked him to do but one look at her face and he did all she asked without any further question. And that is how she came to have a fetish for stinky socks.
