Mistress, dressed in form-fitting latex, commands her submissive to bend over. She coats a sleek, black vibrating buttplug in lube, slowly pushing it into his tight hole. She grins as he moans, feeling the vibrations pulse against his prostate. She watches his ass clench and release, enjoying his helplessness. She then slips into a harness, attaching a thick, realistic strapon dildo. She teases him with it, slapping his ass with it, before sliding it in alongside the plug, filling him completely, continuing his thorough, intimate humiliation.
