I'd always been submissive. Was married in my mid-20s to a dominant woman that pretty much had my number from the beginning; She was pegging me within six months of us being together, but it took more than three years before we introduced cuckolding.
We had moved back to Her hometown, and She began to correspond with Her ex. We talked about it, and agreed She should fuck him.
The night it happened, changed my life forever, and left no uncertainty as to my nature.
As i listened, kneeling on His living room floor, to them fucking in His bedroom, i came twice in my pants without hardly having to touch myself at all, i was so aroused.
When the Wife got me home, She had me go down on Her, which instantly got me rock hard again. As a gracious consolation prize, She then let me fuck Her. i remember, while i was inside Her, i mentioned that i'd never heard Her make the kind of noises She had with Her Bull as when i had fucked Her in the past. It was then that She said the words that left me utterly devastated, changed and more sexually aroused than i had ever been in my life:
"That's because He's a REAL MAN."
i immediately came in Her harder than i ever had before.
It took me years to come to terms with the intensity of that night. But I now know that was the first unmistakable proof I saw of my place in the pecking order, and as a dyed-in-the-wool beta-cuck.
