Mistress Lilli does not like to humiliate people unless they deserve it and that is why she went out of her way to pay this guy to lick her spit. She had the option of doing it to him without caring what he felt but that was not her so she opted to pay him to endure it as she would not be guilty. He would be compensated for it and so it would be fair.
Mistress Lilli does not like this guy. He was super annoying. She had given him a chance to correct himself but he did not. She had no choice but to punish him and she did not hesitate to do it. She spat into his mouth and she also kicked and trampled his balls. She let him go after she had pinched his nipples. He was in pain and he was also humiliated.
