Callisto is a monster hunter. It is her duty to rid the world of any dragon, monster, and any other magical creature roaming these lands. This is why, week after week, she shows up at the tower to fight the witch of the plains.
The fact that the witch roughly tops her anytime Callisto inevitably loses is just a bonus, really.
(A 10k words-long F/F erotica story.)
