I'm a married man and have been for over eight years. All of which I've had gay affairs on the side. It started with a friend of my wifes who stayed with us for a while, just before we got married. A drunken night and a chance to explore sexually, happened because my wife was working her night shift. Purely by chance I flicked onto a gay soft porn film, we watched some of it and her friend asked me if I was aroused. I couldn't hide the fact I was really, as my boner was obvious in my shorts. Swapped blow jobs and my asshole being licked, I fuzzily accepted his invitation to try anal sex. And boy did I fucking love it. Every inch of his eight inch cock found its beautiful way up my rear and by the time he was ready to cum from ramming his cock hard up my butt, I'd already shot my load all over the sofa I was lay on. Him filling my anus was the start of five weeks of gay sexual exploration with him and five weks of daily longing to be fucked and fucked hard. Eight years on and over forty different men later, I still get the exact same thrill from having a guy fuck me as hard as he can give it to me. I always play safe now until I know I can fundamentally trust a guy, even then I only swallow their cum and won't have them cum inside my asshole. The one guy I do allow to fill my bowels after all these years, is my wifes friend who continues to fuck me when he's in town.
