Growing up I had a friend who was always pushing the boundaries of everything he came into contact with. It often got Wayne into trouble, but he just seemed to float through life and he'd go on to the next exciting thing.

In June this year Wayne turned up on my doorstep having supposedly nowhere to live as his flat was being renovated throughout. I'd not seen him in over four years and he looked amazingly fit and well. Giving him our guest room, I told him he could stay for a while. Two weeks later getting home from work early, I entered our home and heard the sounds of sex coming from upstairs. I knew my wife's cries of joy and knew instantly Wayne was fucking her.

He'd always had a reputation with the women and men, and once during a night out in a club, he'd flopped his cock out getting a young guy to suck on it for a while. So I knew if and he was fucking my wife, she'd be taking a very large cock, way bigger than mine.

Sure enough on reaching the guest bedroom, I saw my wife bouncing up and down on Wayne's huge cock. She was yelling and screaming out as she orgasmed, then Wayne carried on fucking her, thrusting upwards to meet her as she sank down. My initial reaction downstairs was to confront them, but seeing her enjoying his massive cock as she was, I actually found myself, if this is the right phrase, "appreciating" him servicing my wife so good.

I watched for some time looking through the door jam and the door itself. Not once did they know I was there, and I began to feel incredibly turned on seeing my wife being fucked so well. Eventually he spun her over, got her to kneel up and with the view I had, I saw his enormous cock slide up my wife's arsehole.

Not once had she let me fuck her arse throughout or relationship. It was for me a no go zone, yet with Wayne's much much bigger dick, she was more than happy for him to fuck her there. And wow did he fuck her arsehole. I've watched porn, course I have, but seeing a woman, and it being my wife too, up close taking a huge cock up her arsehole, was just so horny and so incredibly raw.

This is the bit to me which has changed my life. Watching him shag her, fucking her so hard with his monster cock up her shithole, I came in my shorts. I'd not touched my cock or realised that I was erect, but my five inch dick had become erect and I'd had an orgasm from just watching Wayne fuck my wife. With a wet patch on the front of my shorts, I walked back downstairs, sat on the couch after cleaning up as best I could and waited, thinking to myself "I wish that was my arsehole taking his cock".

When they came downstairs some half an hour or so later, my wife jumped and began to make excuses. It took Wayne to appear and say "Look at his shorts, he's watched us and cum". My wife's demeanor changed and she instantly told me my cock didn't satisfy her the way Wayne's did. I nodded, told her she was right and then said "Whilst he's here you can fuck him, but I want to watch sometimes, maybe". I never finished the sentence because of what I had in mind, I didn't want to say it out loud. But Wayne knew. It was him who replied "Ok, but I say what goes from now on sexually".

Wayne is still living with us, but not for much longer. My wife craves his cock and I sometimes watch them fucking right there in front of me. And my wife can be such a bitch to me when he's fucking her, calling me little dick and a useless lover. But there is now a twist to my confession.

My wife works late shifts at the hospital. And during her shifts nowadays, it's my arsehole Wayne enjoys fucking far more often then hers. He told me last week his new flat will be ready shortly, and has asked me if I'd like to move in with him. He also told me and I know this to be true, he's always loved me, but never thought I was bisexual like him. The fact is, he's always been a bright light in my life and I've always secretly wanted him. He nor anyone else knows this yet, but over the years I have had one off sexual meetings with men. I'd always been seeking someone to replace my feelings wants and needs towards Wayne, but now I don't need to, as in a couple of weeks I will be leaving my wife and moving into a new life with Wayne.
