What do you think this slut finds most humiliating about its treatment? That the only reason her udders are allowed to be clothed is to keep them pressed tightly together for use as another fuckhole? Maybe her subserient posture; arms behind her back on her knees and pushing her chest out? Maybe that she’s kept on a collar and leash like an animal?
Or maybe that although she knows all these things are happening to her, and even though she used to be an active supporter of feminism at Uni, as she looks up at her master worshipping him with her eyes and he looks down at her like nothing more than a piece of meat her cunt drips onto her legs making a pool of pussy goo on herself, and she realises that all she is is a sex toy. She pushes her chest out even more for Master and smiles slightly knowing she’s just an object of use, so grateful to be owned by a Man.
