It was my birthday, and as was the custom, I got to populate the fantasy list. For the last 20 years I have been in the forces, which meant I was away from home a lot. According to my wife it was more than a lot, it was too much. But I loved the job, and was happy to lose some of the perks of a normal life style. Of course, this meant sex was less frequent than other couples, but I believed because it was less frequent, it was much more passionate when we did do it. Normally when I returned from a tour, or exercise, we would be at it non-stop. Over the years we had discussed fantasies; fulfilled some, laughed about others, and if truth be known, kept some of our dirtiest ones to ourselves. One night, whilst reading a porn magazine I came across one of those quizzes that asked about fantasies. We did the quiz together, and afterwards had some great sex, talking about what we would love to have done to us, and do to each other. It was nothing too heavy, but very erotic nevertheless. It was almost Kelly’s birthday, and I hit upon an idea. I told her to write down 5 of her most desirable fantasies, I would pick one at random, and without her knowing which one had been picked, I would make it happen for a birthday treat. The game had been a great success. So much so it became a ritual on both our birthdays. Of course we started off with fairly tame fantasies, outdoor sex, dressing up, etc. and I even got to fuck Kelly in the arse for the first time, when she picked that one on my birthday. Well, I carefully wrote down my big five for the year, and placed them in sealed envelopes. Kelly shuffled them, and picked one at random. As was custom, I took the other four, and without opening them, passed them through the shredder in the study. She kissed me, and gave me my presents before heading off to work, taking with her the knowledge of which of my five depraved fantasies she would be performing for me sometime this week. That night she fucked me, and I tried to get her to let slip which fantasy she had chosen. But she just laughed, climbed off me, and began to wank my rock hard cock muttering “no pussy for impatient boys!” until I came over my chest as her fist pumped my cock. It was the next Tuesday, when I was walking towards my house after work, that I noticed something different. There was a car parked on my drive, and it wasn’t Kelly’s. My heart began to race, as my mind began to hope that one of my fantasies might be about to come true. I fumbled my key in the lock, and let myself in, with a cheesy “Hi honey, I’m home”. There was no reply, but a large envelope with a bright red ribbon around it greeted me as I walked in. I quickly ripped it open, and read the letter inside. “Remove all your clothes in the hallway. On the kitchen table you will find the following: Handcuffs, ball gag, dog collar and lead, and a blindfold. Place the ballgag in your mouth and do up the leather strap. Place the dog collar around your neck and do it up. Place the blindfold over your eyes. Finally, cuff your hands behind your back.” I was puzzeled as this didn’t feature in any of my fantasies, but the hardening of my cock pushed the doubt from my mind, and I stripped. Once naked and equipped as per the instructions I waited. I heard the familiar creak of the stairs as someone descended, my lack of vision heightening my ability to hear. A hand lightly brushed against my taught skin, goose bumps raised to greet the gentle scrape of a nail. A hand grasped the lead, and tugged, making me follow. I was lead upstairs and into our bedroom. A hand pushed at my chest, and I could feel the coolness of a chair against the backs of my legs, so I sat down. Hands were at my ankles, moving my feet, tying something around them. So I was bound to the chair, my arms helpless behind me, my cock rock hard and jutting upwards. Then my blindfold was pulled from my face, and my eyes quickly adjusted to the change in light, and the sight before me. There on the bed was my wife. She was naked, and her pussy was clean shaven and red. It was the sort of red that a serious bout of fucking produces. It was raw and swollen, an angry gash of enflamed flesh. She smiled coyly at me... “This is what you wanted honey, a three some, to share me with another man..” With that, my captor stepped from behind me and made his way over to our bed, his big fat cock hard and ready to plough into my wife again. He climbed between her thighs and slid effortlessly into her depths, her pussy so wet and wanton, neither of them needed to hold and guide his meat in. For the next twenty minutes I had to watch and listen to them fuck. I had to listen to my wife’s moaning and pleading for more, to be fucked harder, to be fucked deeper, to be filled with his spunk. I had to listen to the wet squelching noises of their coupling. I had to listen to the loud slapping and grateful sighs as he periodically spanked her thighs and breasts. I had to watch his back muscles ripple as he humped my wife, her breasts heaving and bouncing as he pounded her. I had to watch her legs thrashing about then clinging onto him as she came. I had to witness his cock glistening with juices as it slid in and out of my wife’s hungry pussy. I had to watch, and have burnt into my mind, the vision that was my wife’s eyes rolling to the top of her head and every muscle of his body go taught as he emptied his balls deep into my wife’s belly. After he came, he pulled out and walked over to me. I was transfixed on my wife, her lifeless body limp and recovering from the onslaught she had endured. Her pussy was battered and gapping, her juices and his spunk glistening, catching the light. My gag was removed, and my feet untied. I guess this man figured I was no threat now. My cock had betrayed me, and was rock hard. I guess I could hardly complain. I moved over to my gorgeous wife, eager to slide my cock into that well used cunt. As I moved between her thighs, Kelly looked up and our eyes met. She smiled. “Does hubby want sloppy seconds?” she teased. I nodded like a child who had been asked if he wanted sweets. Kelly smiled, and taking that as an invite, with my hands still cuffed behind my back, I clumsily lowered myself onto my wife. She was soaked with sweat, her hair clinging to her face. My cock found her sopping entrance, and with one thrust I was in. The feeling was unbelievable. The wetness of her flesh, her juices mixed with his spunk. The looseness of her cunt, her inner muscles tired and limp. The heat. It was too much for me, and I felt my cock twitch, unleashing a torrent of spunk, jet after jet coursing into her well used body. I rolled off her and closed my eyes, trying to take in everything that had just happened. The post climax chemicals racing through me, tiredness, guilt, anger, jealousy, lust. A tug on the lead snapped me out of my daze. Kelly was looking at me smiling again. “That was pathetic” she chided. “I guess this means I haven’t given you your fantasy then” she added. “After all, your fantasy was a three some, where I get to be fucked by you and another man, and I don’t think what you just did constitutes as a fuck. Therefore I think we need to do this again, but properly this time!” Kelly was grinning now. I had been pulled up onto my knees now, and was between Kelly’s legs. My eyes darted between her devilish grin and her seeping gash. I had a horrible feeling I knew what was going to happen next. “So hubby dear, I think you better clean me up so I am ready for Mike’s next load..After all we can’t have our guest fucking a dirty, used, cum filled pussy now, can we? “ I could just about hear her laugh, as my head was pushed down between her milky thighs, and my face was mashed into her raw flesh, my open mouth filled with her gloopy offering....
