Oono, a devoted foot fetishist, finds himself at the mercy of his office superior, Mistress Risa. She commands him to serve her every whim, from being her ottoman to receiving her precious foot rubs. But Risa isn't content with just making him her human chair; she introduces him to a world of pain and pleasure. She spanks him, slaps his face, and finally, she releases her bladder onto him, marking him as her submissive.
