Getting Worked Over

I am married to a stunningly beautiful, successful woman that I love. We have been married for five years, have a nice home and are actively planning to have children. Are sex life is exciting and fun and part of the reason we haven’t gotten pregnant yet is that we have just wanted to enjoy each other’s bodies for a bit longer. I would never cheat on her with another woman but there is a big issue. Starting about two months ago I started fucking my male Jiu jitsu instructor. I’m not going to pretend that I’m some guy who never even considered being with another guy. I had, in fact, over the years had urges that I never acted on that were based mostly out of curiosity. It started when we were having a private instruction, which I am lucky enough to be able to afford as he is highly sought after as a high level instructor. We had done many and I felt like my Jiu jitsu was really improving all though compared to him I am still a novice. Looking back it was just a combination of opportunity and circumstance that started it. It was late on a Saturday afternoon, all classes were done for the day and were doing a private session. Maria my wife was out of town visiting her family and I had no plans accept to relax at home. Our training session was typical with him showing me techniques, working on the intricacies of them and then him moving to a more intense level where he would thwart my attempts but continually instruct me on my mistakes. This session was much different though as he was playful and laughing with me and I noticed, but wasn’t sure it was purposeful, him grabbing my ass and grinding in to me. At one point I did notice he must have been aroused as I felt a very large bulge against me. I continued to laugh along as it was a fun workout. Finally though, we were rolling pretty intensely and he was on top of me in a mounted position. I assumed he was working toward an arm bar or triangle choke and I was working hard to avoid it although my left arm was trapped under him. Instead of trying to improve his position he opened his gi, untied his bottoms a pulled out his beautiful, long hard dick. He put it near my face and simply said is it okay? It was so sexy and his smell was strong and manly. I just took it in my mouth without response. It took a very short time and he moaned so sexily and then released gobs of his cum in my throat. I was choking an swallowing as fast as I could. My eyes were watering but I was so turned on by his moaning. He finally finished and pulled out and his cum was leaking all over my chin and chest. I was a little embarrassed but he was so cool. He sat beside me for several moments and just kept telling me how much you wanted me and how sexy and attractive he thought I was. He asked me if I had any plans and I said not really because my wife was out of town. He asked if I wanted to shower and go back to his place for a drink. I’ll be honest I was just Infatuated with how big and attractive his penis was. I agreed to have a drink with him. At his place we did have a bout a half a glass of wine but we were quickly naked. He treated me like a beautiful girl that he hoped to swoon and before long we were in his bed, my legs on his shoulders and his heavily lubed, monster of a cock pushing hard on the tightness of my virgin ass. It hurt quite a but the moment he broke through and slid deeply in my ass my life changed. He fucked me so gently and deeply and when he started to stiffened and his dick swelled impossibly inside of me reaching orgasm my own hard dick began to shoot hot cum all over my own chest and abdomen. He moaned so sexily again and released his seed deep inside of me. Well laid in each other’s arms for a long time until after a while I began to stroke his cock some more and when he hardened again I sucked another load out of him. I got hime late in the evening so glad that Maria was out of town. My ass hurt for a couple of days but by midweek I was back at his house him behind me doggie style this time, holding my ass and driving himself deep into my bowels. He said he was by clean but I got tested for std’s anyway to protect Maria. Now several months later the s3x with Maria is even more intense and I love her more than ever. She has thrown hints that something has changed but doesn’t seem angry, jealous or pushy with it. Likely because we have screaming, mind blowing sex 3 or 4 days a week. But I am also infatuated, or in love wit my instructor. At a minimum of four days a week I have his fresh cum in my belly or deep in my ass. He is very respectful of Maria but makes no bones about the fact that my ass is his and he wants it forever. I think about his beautiful dick every waking hour and give myself to him every single time he asks. I may just have to tell Maria and hope she understands and maybe the three of us can ride into the sunset. Unlikely, but right now I am happily getting worn out but the most perfect tiny vagina and the most awesome beautiful big dick.
