I have sucked cock for over 35 years and still to this day absolutely love it. You name it and i've sucked it, from forcibly sucking huge ones on my knees to 69'ing other cucks with tiny ones to glory holes in my younger days. But willingly sucking cock in front of your wife for me is the ultimate. Its intense, humiliating, very emasculating and puts me in the submissive headspace I constantly crave. When i've done it without a partner, still fun, but not nearly as exciting.
