You must learn to trust me

Last night we were lying in bed and Princess started to touch me. I was very aroused. First, because I did not have an orgasms for some time.
But mostly, because she wanted to please me, although she was tired.

I gently stroke her back while she was in my arms.
"You are my little sex toy" I whispered in her ear.
Usually, she responds something affirmative, but not tonight.
She said: "Urmel, tonight I am too tired and exhausted for this kind of games."

-- Ouch!

This turned me off. Although she continued to stimulate me, I did not want to come anymore. I though, if I let her continue, she is ruling and not me. She would not want that. If I come now, my orgasm is wasted. It will be rushed. Neither of us will enjoy it.
Moreover, I thought, if she is not interested in the role she chose for herself, there is no point in going any further.
I had lost all interest in making love and with it my erection.

Princess noticed that I was suddenly limp as a wet cloth and she asked if anything was wrong.
"What you have just said really turned me off. I think we better stop." I answered.

"I am sorry. I am just very tired."

"I will not use you, when you are exhausted like this. If you want me to be in charge, you must learn to trust me. Sleep now!"

She thanked me, kissed me good night and fell asleep at once.

I am glad and proud that I said no although I could have had it. I said no, because I knew it would not be good. Only good sex is the key to more and better sex.

I am responsible that we only have sex when we both enjoy it. Otherwise, we will fall back into old patterns, where Princess perceived sex as a burden.

When we woke up next morning, we were both relaxed and really enjoyed our intimacy.
