TMK Sun Wukong x (sorceress/archer/siren) Reader

There are lemons in this so read with 'caution', and if you want to know what a siren is, well the mlp version is that when the sirens sing, everybody/everypony start fighting with one another, and that's what the sirens feed off of just to make their voices stronger. And you'll end up as a hybrid later on in the story.
