Mistress Tess has Her slave strung up in the dungeon, but to add a bit of interest She's placed him in a stress position with his balls locked in a humbler. This position has the delightful result in his ass being presented for Her cane. Mistress Tess recognises that this is a tough position for him so She kindly slips off Her panties and stuffs them in his mouth to make the beating that much more enjoyable.
