Less and less a secret...
I met my wife when I was 30 and she was 23. While she wasn't a virgin when we met, she was very naive and had been taken advantage of her whole life.
She very much enjoyed oral sex, giving mostly, and I was awakened every morning by her hot mouth.
She would bring me lunch at work and while I ate it in my car, she would describe her day so far, and then suck me off before I returned to work.
She had confessed to me when we first met that she did not believe in monogamy. Too many people end up sneaking around and cheating, so why even expect someone to be different?
I had observed how much she loved giving oral sex and regularly commented on whether she had had enough, as she always seemed frustrated after I came. I tried to hold off, but she was just too intense. She would end up masturbating and when I asked her what she was thinking about when she came, it was always the same. Sucking a group of guys.
I encouraged her to explore her fantasies as long as she was discreet about it.
She assured me her oral needs were her well kept secret.
Before long, she no longer had time to meet me for lunch. She was "busy", and I needed to be more understanding.
Long story short, she is now known as the town cocksucker and my life is a mess.
She wins, you lose!
