Monster Maid 3 - Slime Teeth (Nude) (Patreon)

Don't worry - she can make her teeth softer or harder at will. They're more like specialized sex organs that double as self-defense mechanisms. They generally become more supple when she's aroused and rock hard when she's angered.

Progress gif attached as well! Though there aren't too many stages to it because I get sooo fucking immersed in these Halloween girls. It's surreal. '_'
