Long before my wife became a "dominatrix", she tried to get me to suck my own cock.
Unfortunately for her, my lack of flexibility prevented me from doing so.
All she could do was jerk me off to make me cum.
However, she failed to direct the spurts into my mouth.
Then she became that loving wife who, like a ......, put spurts into my mouth with one finger.
She did this one after the other, and I had to clean her finger each time.
I couldn't refuse. The way she did it, with love and care, was irresistible. That's the word that best describes it.
