When mistress Valentina caught this guy doing the wrong thing and he did not want anyone to know. So the mistress did what she does best and she blackmailed him. But she did not want money as he thought she did. Instead, the mistress gave him cum eating instructions. All she wanted was to see him jerk off and when he was done, eat his own cum. He had to.
Mistress Valentina had never made someone eat cum before and it was hilarious for her to do it. She had a lot of fun as she watched the slave eat cum using her instructions. She had scared him earlier to make sure that he would obey her and do what she instructed him to do. That is what made sure that the entire exercise was smooth sailing for the mistress.
Mistress Valentina had an interest in trying cum eating. So she tried it by making this guy eat his own cum. He was not told that that was what he was going to do. Rather, the mistress had the guy think that he was just getting jerk off instructions, which he got at first. But when he came, they continued and turned into cum eating instructions. He had to do it.
Mistress Valentina had this guy where she wanted him to be. He was turned on seeing her hot body especially tattoos and big tits. He wanted her but that was not an option. So he was forced to jerk off and she was gracious enough to give him jerk off instructions. Besides that, the mistress told him to eat his cum or someone else's and he chose to eat his own cum.
