Make your lady happy!
Prepare him for the game by handcuffing him naked on all fours to the bed.
When he's at your mercy, you explain the rules to him:
I found out that I am not satisfied with our sex life.
So I was all the more pleased to see that you want to make me happy. You even promised to do everything for it. I take your word for it!
You will prove to me today that you can satisfy me. You will make me happy no matter what the cost!
Do you understand?
Let's start with a quiz.
I will ask you a question. While I am asking you the question, I will slowly jerk your cock.
If the answer is correct, it continues slowly. If the answer is wrong, I'll jerk you to an edge. But don't you dare to cum!
Don't forget that you have to fuck me to orgasm today!
So think carefully about the answers!
