Put him in latex sensory deprivation

You tell Markus ot put in a tight fitting black body suit. Luckily for him, it has a penis sheath, tight as it may be. Once thats on you can only see his head, you decide to amend that. You Think about putting on several layers and gradually strip him of his senses. You first have him put on a hood that still shows his whole face. Then over that, a hood with holes for the nostrils, mouth and eyes. Then no mouth hole, and finally no eye holes.

Markus hearing is muffled now, but still pretty good. His speech is also muffled, but discernable. You now decide to make him more helpless.

You pick out a pair of latex mittens, they act as a tight bag for Markus´s fists. Next you grab him by the dick and lead him over to your bed. Time to finish his deprivation. You fetch a leather harness gag with just an empty panel over the lips. You place this on his head and strap down the panel Tightly. Next, you cuff him in a spread eagle position on your bed.

You stroke his now erect 8,2" cock and watch him buck his hips, he´s **** now.

You stop and just lie down next to him. He winpers but you don´t care. He´s your Servant now, you decide when he cums.
