Who should be the fire monster girl (Patreon)

We now have Slime in the Discipline Dungeon, and Cat in the Puppetress Dungeon. But What should we put in the Red Maiden's Lava dungeon???? 

1. Snake girl, 

I feel you will get strangled by her with her long tail, so probably a more bondage-related monster girl.

2. Fire Elemental Girl

A more humanoid design and definitely more fire than snake girl, but is it a bit hard to think of a fire-related femdom play, wax play?
