It's time for Mistress Tess and Mistress Melia to bring the pain to the beast. They normally enjoy his roars of pain as he suffers for them but after hooking his flesh with their fish hooks they decide that he needs his mouth stapling shut, not as they'll tire of his roars of pain but simply because they can and it would be rude not to. Strapped down and loving his suffering for them he takes their torment well.
