Well, in my case it has nothing to do with my husband. He is aware I'm adulterous, and he begrudgingly accepts it as it was originally his idea, but my activities out home belong to my intimacy (and that of my lovers, of course). And the joy and bliss of the total, natural union with my black man is a pleasure reserved just for us both.
(Okay, tbh it's true I've had oral sex after having been filled, but only by my best female friend and partner in crime, as I've done to her; but only in some very special occasions on which we and our men have decided we want a full party. When one crosses the line and wipes out shame and delivers herself to pleasure it's not a difficult thing to test some new things when in the right mood.)
