I obviously can't speak for others, and we've had the same mid 50's, white bull for nearly 5 years now. We are all on very equal terms in public, and anyone whah seen us in public or at restaurants would never guess in a million years i'm a cuckold to my wife and him.
Once we get behind closed doors, we'll make a few drinks, put some music on, then they start to make out and get undressed. Withinn 10 or so minutes, I usually get on my knees and start sucking his cock... and to be honest, I think we go through this same routine to set the mood, dynamic and establish an alpha/ beta hierarchy in the room for the next couple of hours. I have sucked his cock many, many times sometimes while fingering his ass, sucked his balls, rimmed his ass, and always swallow every drop of his cum... but once we are done, we'll get dressed, chat some more and we go back to our normal selves, he'll kiss her, give me an embracing hug, thanks us, then just go our own ways until next time. I think its mainly our mutual repsect for each other, is the reason we still play 5 years later.
