Don't underestimate the power of the big cock, when a woman realize that she choose the wrong stud, a husband with a little dick and uncapable to make her pregnant, what can she do ? Stay with that guy because of a thing called love in the movies but that don't really exist in reality, getting frustrated all her life and ending up by hating him or let herself go and enjoy the fun with a big dick that gives her the enlightment of a satisfied pussy!
I'm an old guy and i have seen so many people around me getting cucked and cucking that i don't care, that's a very frequent thing in real life.
In stories everyone sees the error of their ways and does the right thing in the end, right? Sure. But in real life, people are ignorant. People make all kinds of bad decisions based on all kinds of bad information. Our experiences and desire can blind our logic.
Add pregnancy, motherhood, lifelong goals and ambitions, dreams...Life just gets messy. People rarely make good decisions, especially when so much is at stake. Is it about sexual fulfillment and the size of the cock? Rarely in my experience. But, add in the maternity issues, and all of a sudden the ability to have an orgasm or the size of the dick can easily betray our logical sense.
And there are just some people who are shallow wastes of human existence. Logic means nothing, Love has no meaning. Dedication to a marriage and a partner is worthless. We can get to one ending of this story and call it porn logic. Try to appease ourselves with what we think a woman would actually do. But reality is far stranger than fiction.
