For me it went way beyond the sensation of sucking his cock, because IMHO it is the intensity of how he took control. Keep in mind that my wife insisted I meet him alone first, before she did. Afterward, I knew why. I had written about my first experience, and here is part of it:
I was both excited and nervous when I opened the door. His first words, "Strip and get on your knees!" I was shocked, but obeyed. As a sub cuck, I always obeyed. As I knelt, "Eyes down; hands behind your back." He stood before me, still dressed, and definitely in-charge. "Your wife and I have talked quit a bit over the last couple of weeks." I thought, 'she never mentioned that.' "She said that you are a cock-loving cuckold and you beg her to fuck men because you need cock, and you have slept with gay men." We had mentioned that I was a cuck and bi, but not that type of detail. "Well?" he asked; I said "Yes." He commented that although my wife loves sex, she rarely has an orgasm, and fakes it a lot. I was shocked; she never told me that detail. I knew she struggled with orgasms, but not to the extent he talked about. I wondered why she told him and not me. He talked about the times they had phone sex and how badly she wants to be a black man's whore. Admittedly it was hurtful to hear how they had shared without me knowing. He also talked about she needed to learn more about truly cuckolding me. He talked about how he taught other wives to dominated pussy-boi hubbies like me, and how he will own her pussy, but first he will make me his fag bitch. Although those words initially shocked me, his demeanor and commanding presence seemed to make me feel very submissive, more importantly naturally submissive to him. With that he undressed. He stood back and I admired his beautiful black body and he big cock, fully erect! "What do you want white boy?" "I want your cock." "Come over here," When I started to stand, "Crawl bitch!" I had been dominated before, but never like this. I could tell with him that it was not a game. As I approached him on my hands and knees, he said, "You white boys are all the same." "Beg for my cock." As I did, he had me promise to deliver my wife, and that he will own her the way he will own me by the end of the night. At that point, kneeling before him, hungry for his cock, I traded my wife for his cock. I had loved cock going back to my teens, but never like this. As I hungrily sucked his beautiful black cock and worked hard to deep-throat him. I was so turned on. But when he said, "You don't suck like any bi husband I met; you suck like a faggot." That made me even hotter and I guess it showed. "Your wife was right, you are a faggot!" He grabbed my hair and pulled my hair back, "Say it bitch." "Yes I am." "No, say it!!" "Yes, I am fag." I went back down on his cock and sucked him, and at times he face fucked me, calling me his bitch, his fag, his homo. Sometimes sucking cock I would tire, but not his, I loved his big cock and how he treated me. When he came, I struggled to take it all. What dripped out of my mouth, he said, "Lick it up." I did.
