A cuckold's ultimate degradation unfolds as he kneels before his Mistress and her bull, watching them fuck passionately. He's ordered to follow the bi-fetish cum-eating instructions, his face inches from their grinding bodies. The bull grunts, his cock throbbing, and the Mistress guides him to cum onto the cuckold's tongue. He hesitates, but a swift slap from the Mistress reminds him of his place. He tentatively licks the bull's cum, his face twisting in disgust, but the Mistress praises him, "Good sissy. Now lick my pussy clean."
