I'm not sure what my gorgeous wife saw in me; although my friends said it might have been the fact that I'm independently wealthy from my parents inheritance. For whatever reason, I was glad that a nerd like me was able to snag a sexy (36D-25-36) wife like Sultana. For the first several years of our marriage, my wife was sexually frustrated which she made known to me on numerous occasions. The source of her frustration was my relatively small cock. Although 5" long when I'm fully aroused, it is very thin and almost invisible when it's soft. On more than one occasion, she threatened to reveal my lack of manhood to our friends unless I did exactly what she wanted both in and out of our bedroom. It was in this manner that she got the complete upper hand with me, eventually using me as her sex-slave. She enjoys x-rated B&D videos and has modeled our lovemaking over some of the scenes in those movies. I knew I should have protested stronger, but to tell the truth, I rather enjoyed playing the surrogate hubby that was forced to lick his wife for hours before being allowed to enter her. Often, after I had brought her to climax with my tongue, she simply had me play with my cock until I spilled my seed in my hands and lapped it up for her viewing pleasure. As I said, I didn't find her domination of me all that bad, until the day that she brought a black man home one evening. They entered the living room where I had been vacuuming (at Sultana's demand) laughing coyly together and with their hands all over one another. Sultana introduced Nate to me as a really good friend that she had meet at her health club. If I had any doubts as to their real relationship, they were erased when Nate said to me, "Your wife tells me that you can't satisfy her with your puny cock. Lets see it, white boy." My initial reaction was shock, but that was followed by an overwhelming feeling of humiliation as my face turned a crimson red. There was something in his voice that told me he was very serious and his strong muscular frame told me I'd better do as told. It didn't help matters that Sultana demanded, "Well, what are you waiting for?" I took my little dick out (only about 1 Ç" long in it's limp state) as Nate and Sultana had a hearty laugh. "Show him what you have, baby," my wife casually told this black stranger to me. When he did, I was privileged to see the largest cock I had seen up to that time. My wife told me that she wanted to show me what a real man could do for her. I was shocked as Sultana removed all her cloths (except her nylons, garter belt and high heels) and proceeded to get on her knees and give Nate a sloppy long blow job! She apparently had no concern about my reaction to all of this! After sucking him off and swallowing all his cum (something she had never done for me) she told me to sit down because I hadn't seen anything yet! I guess she was right, I was amazed that even though he had just blown a load of cum into my wife's mouth he was able to get another immediate hard-on and enter my wife's pussy, doggy style. My mouth dropped open and I could not react (although my little dick was actually beginning to grow to its full 5" size) Needless to say, I observed her first orgasm from a cock, which I had never been able to give to her. When they were finished, Sultana told me that it was my turn to do what I do best. I knew what she meant but was reluctant to lick out her pussy, knowing it was full of Nate's cum. Nate's command of, "Get to it, white boy." was enough to convince me to do as told from my wife. Nate laughed and whipped his wet cock off on my bare ass as I bent over to suck my wife to her second climax of the evening. Nate stayed the night in our bedroom with Sultana and I was relegated to the spare bedroom to listen to their lovemaking all night long. Since then, Nate has become a regular visitor to our home along with several of his well endowed black friends. I can't deny that my Sultana is well satisfied now, walking around with a broad smile on her face most of the time. However, I don't enjoy the amount of humiliation I'm forced to endure from Nate and his friends. I'm often made to suck them first to get them up for my wife (especially after their third climax with her) and Kevin (a bi-sexual friend of Nate's) will often use my ass and tongue for his deviant pleasures. I know that I've allowed all this to get out of hand, but I knew if I lost her I'd never be able to have another women as beautiful and sensual as my Sultana. I'm trapped to be her and her black studs love-slave.
