I was working away from home much to my wife's annoyance. There was a party at some friends house that my wife wanted to go to, but as I was away she wouldn't go on her own. I had told her that it was alright to go on her own. Kay our friend would see that she got home safely. Annie said she wasn't sure. We left it like that. Then we had a breakthrough on the job and what was a ten day job suddenly turned into a four day job. I tried to ring Annie to let her know, but each time I rang our phone line was engaged. The next morning we did our final checks and tests and found that it was all working correctly. It was just a matter of fitting all the covers and safety devices back on. Mike said that he had nothing else to do so myself and Alf could make our way home. So I set off for home. I arrived home at a little after eight on the Saturday evening, Annie wasn't home so I guessed that she had gone to the party. After a quick shave and shower I decided to make my way to Kay and Phil's house and catch up with Annie at the party. By the time I got there it was just after nine o'clock. The party was in full flow and heaving with people, most of whom I didn't know. As I got a glass of beer I asked Kay where Annie was. She told me that she was here somewhere, the last time she had seen Annie was when she was talking to Herman. I didn't like Herman, he was a pig of a man who always thought he was right. I thought that Annie didn't like him either. Perhaps I was wrong. Sipping my beer, I wandered around indoors but couldn't see her. So I wandered out to the garden and still couldn't see her. Back indoors I wandered upstairs and looked in the bathroom and the bedrooms. I still failed to find her although I did find Herman shagging Lilly, one of Annie's friends. I wandered around asking people I knew if they had seen Annie. Nobody had. Then I went back into the garden. Still no signs of Annie. Then I spotted a man come out of the shed at the far end of the long garden. I sat sipping my beer wondering where Annie had gotten to. Then a second man exited the shed. I was intrigued at what they were doing in the shed and wandered down to the shed. Even before I got to the shed I could tell that there was still people inside due to the cheers and other noises that came from the shed. Then I heard a groan. I knew that groan, it was my Annie. Stupidly I wondered what had made her moan. I looked through one of the dirty windows. I was shocked my Annie was spread across a table. Her dress was missing and her tits were hanging out of her bra and they were being fondled by two men as another was between her legs and pounding his cock into my wife's naked pussy. There was two if not three other men in the shed. All of them were in various stages of undress, but all had their cocks out. Then one of the men stepped forward and fed his cock into Annie's mouth. She seemed to be greedily sucking on his invading cock. I wanted to go into the shed and smash the hell out of these men that were violating my wife. But when I tried to move my legs wouldn't move and I could not take my eyes off of the scene before me. The man fucking my wife came, and as he withdrew a large amount of cum came out of my wife's pussy and ran down her arse and dropped onto the floor. The man quickly redressed as another stepped forward and roughly slammed his cock into my Annie's pussy. Then the man was leaving. As he left he saw me watching and said that I should get in there as this ones a game bird and that she needs lots of cock. I was shocked and couldn't say anything. Then the man with his cock in Annie's mouth came. He too dressed and stood watching as another man filled Annie's mouth with his cock. One of the men playing with Annie's tit suddenly wanked his cock on her tits and spunked all over them. He too dressed and stood watching. The man fucking Annie came in her and was soon replaced by another man. "Fuck me, she's fucking soaking down there and talk about sloppy. It's like waving a banana in a tunnel," the man said as he fucked my wife. The man fucking my wife's mouth came and some trickled down her cheek and into her hair. The last man took his place and started roughly fucking her mouth. Both men finished pretty much at the same time. Now all of the men were either dressing or dressed. I heard one say, "what we going to do with her?" I heard another say, "Leave her someone else might need a fuck." with that they were just about to leave the shed. I quickly moved to the back of the shed out of sight. I watched as they all sauntered up the lawn towards the house. I went back to looking through the window. Annie was still laid there not moving. I heard noises behind me and saw two more men coming down the lawn. I walked up the lawn as if I had just come from the shed. "Was she good," one of them asked. I muttered yes and then the men entered the shed. I went back to the window. One of the men already had his cock in Annie's pussy and was roughly plowing her pussy. The other man was just about to stick his cock in Annie's mouth. Then I could see her sucking it in. After a few minutes the men swapped places and fucked her pussy and mouth until they both came. More spunk ran down Annie's arse and her cheek. This time I left and went back into the kitchen. I got a stronger drink and as I poured it a man I didn't know spoke to me. "Have you been to the shed yet?" he asked, "There's a cracking bit of stuff in there doing a turn for anyone that wants one." I told him I had already fucked her. "Bloody good isn't she?" he said as he walked away. I was stood thinking what I should do about Annie when Kay entered the kitchen and asked if I had found Annie. I lied and told her no I hadn't and that I thought that perhaps she had gone back home and perhaps and I should head off back there to catch up with her. She kissed me on the cheek and thanked me for coming and then walked away talking to another guest. I decided to take one more look in the shed before deciding a course of action. Back at the window, Annie was now standing and was bent over the table and one of my so called mates was was behind Annie slamming his cock into her pussy. Worse still Annie was thrusting back at his cock, obviously enjoying it. I discovered that I had a hard on and thought about taking a turn. Noise coming from the kitchen had me hiding behind the shed again. Then I decided to go home before I got caught and humiliated that my Annie was being the center of this party. I drove home and sat thinking about what I had seen. This only made my cock throb harder and eventually I had to relieve myself. It was almost eleven o'clock and I decided to get in bed. As I lay there I had to wank myself a second time. I was slowly dozing when I heard a car pull up outside the house. I went to the window and saw two men getting Annie out of a car. She could hardly stand and one of them held her against the car to stop her toppling over. Then he was kissing her and his hand had gone up her short black dress and was obviously playing with her fanny. The other man joined him and turning her sideways he became her prop by leaning her against himself. His hands were wrapped around her fondling Annie's tits. I thought they were about to fuck her right there outside my house on the pavement where any neighbor could see. Then a car headlights started to light up the road. The two men removed their hands and helped her to the front door and after a few minutes I heard the key in the lock and the door open and shortly shut again. I heard their car drive away. I could hear Annie stumbling around downstairs and went down to her. She looked clean and smelt as she does when she comes straight out of the shower. Somebody had spent the time to clean her up. I helped her to ascend the stairs and undressed her. I removed the dress and her bra. Her panties were missing, someone had kept themselves a trophy and her tits looked red where they had been mauled so much and her pussy was also very red and still gaping open from the heavy use it had been put through. I lay her in bed and covered her over. She was asleep in seconds and was snoring. I went and got into our spare bed thinking about what had happened. Do I kick her out, telling her what a dirty slut she was or do I keep it to myself and hope that it was a one off. I have no idea what time it was, but I did eventually get to sleep. Next morning Annie was up getting herself some breakfast. I noticed that she was walking rather gingerly, taking small steps. "Hi hun. Didn't expect to see you yet, you were meant to be away for several more days," she said as she handed me cup of tea. I told her that I got back very late last night and slept in the spare bed. Then I asked if she had gone to the party. "Yes only for a short while. It wasn't very exciting," she lied to me. I sat there drinking my tea wondering if I should tell her I saw her or try to forget about it.
