You have a point on the taboo factor. No you are not suppose to be spreading your legs or sucking the cock of another man while you are married. Add the taboo of the interracial aspect and it is like you are really flaunting your pussy power around. Yes going against "good" society is also thrilling. It depends on how much you want or happen to have in front of others eyes. To some it is a secretive thing, where others may have the opportunities and want to openly show their cuck lifestyle and , I know from personal experience, it can be a thrilling , humiliating, exciting time in your life. I had the opportunity in a relationship to have my then g/f openly fucking other men. She was not shy about it and her friends and others and a bar we hang out at learned that also. She was just the right girl that loved to fuck, liked variety, and hooked up with me. I worked, she didn't so she had plenty of time to play. I was very happy with this and loved the humiliation of everyone knowing I paid for everything and she was out fucking whoever she wanted. I have come home to an empty house, a locked bedroom door, passing guys out the door, in the driveway, and have either joined in, waited in the living room, or left and came back depending on who it was. But yes the taboo things were extra kickers of fun.
