This guy was dying to have fun with this mistress and she took advantage of that to lead him on. Instead of the fun he thought that she wanted to have with him, he found himself being tortured and humiliated by the mistress. She started out by giving him a handjob and it later turned out to be that she wanted to ruin his orgasm which she did shortly thereafter.
Mistress Nyx started out with the intention to ruin this guy's orgasm but it turned out to be a full blown dick torture. The mistress squeezed his dick and she made it a painful affair. She slapped it as well and she squeezed his nuts for good measure. The guy was tied so that he would not fight back or resist and he was made to feel pain he had never felt before.
