He was very handsome. Divorced, upmarket, educated. Fifteen years younger than Beth. Quite well endowed. Twenty-five years younger than me. He adored Beth. Truly adored her and very excited whenever he fucked her. That made her feel like she was eighteen again. He had been fucking her for about six months now. Normally I’d get to be there to watch and if appropriate to join in. But he didn’t want anyone there, so Beth would describe it to me when she got home and show me an occasional cell phone picture. One of the roughly 50 photos I saw was of her sucking him off. His cock was huge. I thought perhaps nine plus inches. Very thick and smooth. I was both intimidated by the size, yet very turned on because Beth has always liked larger cocks. And she never kept it a secret. He was one of the three or four most physically satisfying men she had ever been with. I’m not a slouch. She easily climaxes with me - out of affection and familiarity. But when you have had sex with someone several thousand times, the fizz tends to go out of the champagne. Especially for her. Over the years I had became her mate, her confidant, her Rock of Gibraltar, her partner in crime. But not her big thrill. He, like a few other men in her life, made her knees weak when she thought about him. Sometimes chemistry, combined with newness, trumps love and fidelity. Were he her age and had we not had children, I would have felt deep concern. But he was so much younger than her that I did not perceive him a danger to our marriage. And having no concerns about our bond, I found her accounts of her 10/10 orgasms with him thrilling. The thought that the mother of my children felt such physical pleasure with him drove me wild. Perhaps I should tell you at this point that it was Beth who introduced me to swinging. Not the other way around. She had dozens of men before I met her, so I had long accepted the fact that I was not the only one who satisfied her or caused the fire in her belly to burn bright. I’m not a cuck. I’m something else. I’m the husband of a hypersexual woman. A woman who sometimes cannot say no to a new opportunity or an attractive new man. And since she traveled a lot on business, over the years those new men added up to many dozens. And then there were our couple swaps and our threesomes. But to return to the moment. Beth knew how much I wanted to actually see her have sex with him. And she has always said that the most excited she got was when I was there to share her. Comforting words, but I had to take them for what they were because when she was on her own I had no way of telling what was really going through her mind or happening to her body. When you are married to a hotwife and she does not treat you like a slave or a cuck, you simply have to assume you are good, but some others are too. When I was there to watch or participate I judged her pleasure with how many orgasms she experienced and on occasion when she asked them to do very taboo things to her. In any case, she finally convinced him that it was important to her that I get to see them. At first he was a bit reluctant, but she implied that if he wanted to continue having her as a lover, it would be wise to say yes. And so it happened. I’m not going to tell you everything that happened that evening. It was hot and steamy, but if I spelled it all out this would turn into a thirty minute long read, and quite frankly, sex sagas can become a bore after 10 minutes. So I am only going to tell you about a short slice. Beth had been having him about 15 minutes. She had her first orgasm on his tongue and her second on his fingers. She was now on her back, spread eagled, with his huge cock plunging deep inside her and then almost completely withdrawing.....and then back in and out. I could see and hear that she was getting close to climax again. That wasn’t unique. Over many years I had watched her hundreds of times having orgasms on the cocks of other men. But he was special. Someone who she told me was one of the very best. I was mesmerized by how his huge cock plunged in and out of her. I knew she was close to cumming. Her sounds, the thrashing of her legs, the look of her face. Suddenly he could hold out no longer and exploded in her. He moaned and thrusted and thrashed and I could hear the squishing if his sperm inside Beth’s vagina. And the thrill of making her young lover cum threw Beth into fifth gear. She reached out and pulled me to her mouth and kissed me and fucked my tongue with hers and screamed her orgasm into my mouth as loud as she could and at that moment, the excitement of feeling her pleasure with him caused me to spontaneously ejaculate. Huge orgasms, all around. Win-win-win. We were all totally drained.
