Svenja's slave is continually used as living seat. She is testing how long he can stand under to be beneath her face sitting ass. Again and again she pressed her butt while firmly against his face, just the way Svenja likes it. Full weight face sitting is something Svenja uses as well to subdue her slave – as an optimal method of education to increase the stamina of her slave. And she will extend the face sitting sessions, whether the seat cushion likes it or not.
