Now now, be nice. Little Samantha's not a monster... per se. She's just a little half-breed. Not her fault that her daddy was an incubus and that things like to do naughty things to her.
(Character's name is Samantha Grey. Art was commissioned from Nitrotitan as referenced in the tags.)
To be fair, the one going down her throat is actually connected to the air outside, so it may have given her a breathing tube which pumps air into her as it fucks her throat. The look of panic/surprise might just be from being encased in a sentient goo that means to have its way with her.
