Mistress Alpha was fed up with this guy because he was a pain in her ass. She wanted him to understand that she would not let him get away with the nonsense he did. That is why she came with a used condom and told him that if he pissed her one more time, he would have to eat the cum in the used condom and she would make sure he did it as per her cum eating instructions. He got scared and stopped messing with her.
