That’s why he’s invited them there, for their enjoyment and her shame. She complies, knowing that the watchers behind the mirrored wall that faces her backside are enjoying the scene, enjoying her humiliation as she bends forward, her gown opened, her behind displayed. And then, after she’s done so, after she’s felt him strip her panties off entirely, to move her hands up to spread her cheeks and reveal everything between them. Then tells her in a loud voice to reach back and pull her panties down below her buttocks. He has the humiliation gown completely opened now, and he pauses to admire the view. Who can see her there in that humiliating posture already disgraced, with the greatest part of the mortification still to come. She looks at the mirror in front of her, wondering who’s behind it, looking out at her. She looks straight ahead as he opens the gown to reveal her behind, her red strapped cheeks clenched tight underneath the sheer white punishment panties he’s exposed. Behind her, methodically opening the flaps of the humiliation gown he’s made her put on, exposing the seat of her pantied bottom to the mirrored walls of the punishment room.
She lies forward over the sodomy stool, feeling its hard surface beneath her, listening to him at her rear, preparing her behind for chastisement.
