I tie my big cock sex slave to a post with intricate rope, encircling him like a shark and displaying my body to him setting his mind racing. Once he is tightly bound I stimulate his cock and nipples with my e-stim. Rubbing myself against him and jerking his big dick and kissing his lips I get really turned on when I'm making him shake and pant, so I remove my underwear and back up onto his throbbing dick. I want to feel those pulses inside my pussy. I get him right to the edge before pulling away and denying his orgasm. How cruel a Mistress I can be.
