Mistress Nyx felt that this guy needed to be rewarded as he had done what she had asked him to do and done it marvelously. So she rewarded him with jerk off instructions. And to make it even better for him, the mistress undressed and she let him use her tattooed naked body to jerk off. He saw her sexy ass, big clit, her small tits and clean shaved pussy and he could not help but cum.
Mistress Nyx wanted to make this guy jerk off to her instructions. But the guy was not enthusiastic about it so she knew that the only way for her to do so was to force him. So she did not hold back and she had to make sure she forced him to do it. She told him if he did not do it, she would crush his balls and so he did it out of fear.
