I have lent my slave and I am dissatisfied

I had lent my slave to Lady Dark Nuts and got the Raport of his services from her here some things did not fit on the one hand he was stingy and has booked a too small hotel room but she has already punished that

But what made me very angry was that he couldn't control himself, he actually had an orgasm!!!! Ok, he was dry and ruined, but he still couldn't have one without permission.

That's why I tested him and trained him and spoiled him massively and milked his cock and he was lucky, he didn't come but that's not the end of the exercise... Part 2/2
