I have encountered some hubbies who do not want me to kiss their wives. I have always prided myself on my kissing skills, and so I can understand the fear or concern over it. When a wife kisses me, she is instantly wet and aroused.
I don't want to get sidetracked on this discussion, but kissing alone isn't what makes the scenario an act of submission. It's started with a kiss, but my deep voice, making commands in her ear in a whisper, as I tell her what I am going to do to her body, usually follows.
But before any of the physical, I have established real communication lines with the wife and hubby. We know where we all stand. The hubby knows his role and that how to be loving and supportive to his wife. Without this element, all the kissing in the world isn't going to be sustaining. Its a hot night- but it's not full cuckolding.
And to me, the ultimate act of submission of a wife to a Bull is giving herself completely over and saying "I'm yours!"
As a Bull, I feel responsible to ensure that my "hotwife" gets the pleasure she deserves and she can go to her hubby for the love and relationship aspects. She gets the best of both worlds in my opinion.
