Normally, I'm a very jealous man, so the events of the last couple of months leave me puzzled. Excited and angry, but also puzzled. I've lost girlfriends because of my jealousy. I had it under enough control to ask Wendy to marry me, even though I knew she'd had a previous lover. She told me before the first time we made love several weeks before I asked her to marry me. She wouldn't tell me anything about him, just that she could never marry him and that it was over. My jealousy made me press her a little for more information, but she refused to tell me anymore. Control over my jealously kept me from pressing too hard, and Wendy didn't break our engagement. I always felt extremely lucky, as Wendy is an absolute doll of a woman. She's short, but she has a beautiful face, a magnificent bosom, an outstanding bottom, and great legs. She's also funny and very intelligent. Wendy comes from a large family of Catholics. Her mother is gorgeous, too, despite having lots of babies, which kind of let me know what Wendy would look like when she was older. All of her sisters and brothers are good looking, and most of those older than Wendy are already married. The one who isn't was in the military. He served a couple of tours overseas, and missed our wedding. Anyway, my story really starts a couple of months ago when Wendy and I held a small party for our family and friends to celebrate our one year wedding anniversary. Wendy's brother, John, was out of the military and was the only person at the party who hadn't been at the wedding. We all enjoyed ourselves, finishing three bottles of a very good wine. People began leaving before it got too late, all of them congratulating us on our happy marriage. Finally, everyone was gone except for Wendy and me, and her brother John who was living with his parents until he found a permanent place to stay. After everyone had left, John asked if he could kiss Wendy as he wasn't at our wedding and didn't kiss her when she was just married. Of course, I gave my permission. The kiss John gave Wendy was not the kiss a brother gives to his sister. It was a kiss a man gives to his lover. And Wendy kissed him right back. The kiss started with them standing by the sofa. Wendy's arms went around John's neck, and John's arms went around Wendy's waist. After a little bit, John's hands started wandering, up to caress Wendy's big breasts through her dress, and down to caress her beautiful bum. To my amazement, I got hard watching them. I was extremely jealous, but I also wanted to see how far they would go. Wendy made no objection when John raised her skirt and slid his hands to the top of her panties. In fact, she ground herself harder against him. He pulled her panties down, and she stepped out of them. He ran his finger along her slit, and it came out really wet. Wendy's pussy was obviously ready for his cock. Wendy let go of his neck to unzip his pants and pull his cock out. My cock was straining my pants. I was angry, but I was also as horny as I'd ever been in my life. I knew if I didn't stop them, John would be fucking his sister, my wife, right in front of me! I didn't stop them. Wendy lay back on the couch, spread her legs, and pulled John's cock to her pussy. John has a big cock. I usually have to really work to get Wendy's pussy wet and loose enough to take my cock, but John's even bigger cock slid right in. Wendy helped. She put her legs around John's waist to pull him in and raised her hips to make sure he was all the way in. I could tell that she was having an orgasm while she was rubbing her clit against John's pubic hair by the way she was shaking and moaning into John's mouth as she kissed him. I came just after Wendy started coming. Actually, I started coming just after I realized that John wasn't using a condom. Wendy and I had been trying to start a family since we'd been married with no luck, so I knew wasn't using birth control either. Just that morning, Wendy had told me that she was ovulating today. Realizing that it might be her own brother's sperm fertilizing Wendy's egg made me come. I was extremely angry and jealous, but I was also shooting off in my shorts! Wendy's orgasm triggered John's. He clinched his butt cheeks as he squirted his sperm into my wife, his sister. When I could stand, I went behind and could see John's sperm oozing out of Wendy's stuffed pussy. I got my cock out, and when John got off Wendy, I got on her and slipped my cock into her spermy pussy without saying a word. Wendy looked surprised when I bent down to kiss her, but her legs went around my waist and her pussy tightened on my dick. She started coming again almost immediately, triggering my orgasm, adding my second load to John's first load in Wendy's womb. When we had all calmed down, Wendy asked, "Are you going to leave me?" I said, "No. John's your first lover, isn't he?" Both Wendy and John said, "Yes." I asked, "Did you use condoms when you were together?" John said, "Yes. I know it's against our religion, but I didn't want to get Wendy pregnant." Wendy added, "We couldn't get married. We still can't. Besides, I really love you. Aren't you jealous?" "Extremely. But I'm also extremely excited. Watching you two was the most exciting thing that's ever happened to me!" I said. "So you're not going to try to hit me?" John asked. "No. I doubt if I could anyway, but I really don't even want to," I said. "So what are we going to do?" my beautiful wife asked. "Well, why don't you call your parents and tell them you're spending the night here, John. Then let's all take off our clothes and go to our bedroom," I said. "Are you sure?" asked Wendy. "I don't want to hurt you." I said, "John never fucked you in your beautiful bottom, did he?" "Nooo," Wendy said. "Well, I think that since John got your pussy cherry, it's only fair that I get your anal cherry. Besides, if we do it right, I think you'll really enjoy having John in your pussy and me in your ass at the same time!" I said. * * * Well, John lives with us now. He has the spare bedroom to keep his things, but all three of us sleep, well use, the same bed. I got Wendy's anal cherry, and she enjoyed her experience with two cocks in her at the same time. She still does. Oh, and Wendy's pregnant. Two months pregnant. I think John got her pregnant on our anniversary. I had myself tested, and my sperm count is low. Of course, it could be low because I deposit so much of it inside my beautiful and loving wife. As I work all day while John stays home to help Wendy with the house, I think he's fucking her more than I am. He's since told me that fucking Wendy without condoms was the best thing that ever happened to him. I think I agree. Wendy and I plan on having many babies. John will help making them, but he'll also be changing a lot more diapers than I will be.
