Insane sexual domination with a thirsty slaveboy

As you can imagine not all of my clients look young and cute. It is always a surprise when someone opens the door. This time it was a nice surprise. A handsome young man was waiting for me and he only had one problem: he lost his job and owed about 30 000 CZK to a bank. Those rather small loans are common here in the Czech Republic but still they can cause serious problems to the lender when he gets late with the installments. So you can guess what I offered him. He agreed to it and took it even with some sort of special humor. So I decided to play a little bit with him before the real sex gets started. After all I want to teach them a lesson they won´t forget in order not to get into debts again. Everything went fine until I started to fuck him...
