I don't see anything that humiliates the third person, like a husband. I only see a very experienced woman in sucking cock's. Look how she handle his balls. For sure it is not the first time that she is doing such a thing with two man's. Non of them is her husband for sure.
Sometimes a woman loves a man, but wants more sexual satisfaction than he can provide. If they really love each other they can agree to let other men fuck her with the husband being able to watch. Being able to see other penises with her blessing.....a wonderful thing for those who have the same obsessions that I have. I would also want to orally clean her and the fellow. This is hot!!!
