Tessa's head is swimming from the feelings welling up between her legs.  Her insides are on fire, the precum igniting her every nerve ending.  Despite this she fights the demon Ignacius as much as she can, trying to close her legs.  Her eyes are rolling to the back of her head as wave after wave of pleasure crashes upon her.  "Not...nooh...noot until you promise me...what I want."  Her sobbing gasps of pleasure show just how much willpower she has, that despite everything she's trying to negotiate and take what she wants.
