No, he is just a slave, who cares?

He lies there as if he was still waiting for something... You look at him, his penis is still erect... You spit on it and tell him:

Lily: You pathetic slave, you are no more than a toy to cause people pleasure, don't expect me to make you cum. You may go now.

Now that he has brought you some pleasure, you can depart. You meet Johanna outside, she gives you a strange look, but doesn't ask about what has happened inside. She can imagine, as she had sex with Peter many times before, but seeing her lady do it so casually with a slave has left a certain distaste for her... But her opinion is not of your concern.
