That's too bad that you haven't had the opportunity to fulfill your cuckold fantasy. I would take that fantasy any day over just about every other fantasy!!!
She loves to have other men's cocks inside of her, stretch her married pussy and fill her up with their semen. Its just the way it is, this is sex to her, its fulfills her sexual desires. She won't have it any other way, it wouldn't be sex to her or me for that matter. The scent of another man's cologne on her neck and body, his freshly ejaculated semen in her married pussy and mouth, that's what its all about!!
