It started out simply enough, with Missy coming to HELL! because she knows at her core that she needs to be punished. Now the slut is on the bench, a hook in her asshole and her ass suffering all the torments HELL! has to offer at the hands of BrutalMaster.
Look at her face, and see her joy at being of use in her agony when she is asked if she is happy to be in HELL! Her answer shows her absolute delight, even as she is made to scream a moment later.
Missy knows what she is, what she deserves and where to find it.
