My wife and I had been into swapping for quite some time and had probably hooked up with about twenty different couples. We had also attended two parties one of which was more of an orgy. It was my first time with more that one woman. Grace my wife had a threesome with two men before we married and had another on that night. We were enjoying this lifestyle and discussed having an open relationship. The only real rule was not to get fixated on one person and always come home. We then agreed that bringing home another person was OK but who ever brought someone home had to use a spare bedroom. It wasn't too long after we agreed to the rules that Grace brought someone home. I didn't know him. He was a big guy, probably in his late twenties compared to our early thirties. I lay in my bed and heard the guy fucking my wife. It went on and on and on. It was about one p.m. before they finally went quiet. Then I was woken by my wife letting out a large groan. I thought he was hurting Grace and was out of bed and about to crash into the spare room when Grace told him not to stop and then groaned loudly again. I didn't know what or how he was doing something to Grace, but it was certainly working for her. Back in bed it was nearly three o'clock when they finally finished. I was glad the next day was Saturday as I had had little sleep. Next morning the guy was sat eating cereals and drinking tea when I entered the kitchen. "You have got one hell of a great wife there," he told me. I told him I knew. "She's by far the best screw I've ever had. Can't wait to fuck her again." I left the kitchen without any tea or breakfast. Fortunately he left about twenty minutes later after kissing and groping my wife. After he had gone I asked Grace what he meant about next time. Grace informed me that was just wishful thinking as she hadn't and wouldn't be invited back. I was concerned and asked had he hurt her. She answered not in the way that I thought and as she stood there she lifted her dress and showed me her naked pussy that was still gaping wide open. She told me that whilst he was no longer than my seven inches, he was probably more than twice the thickness of my cock. Hence the gaping pussy. She said it was good, but was also bloody painful especially when he got too excited and plowed his cock into her pussy. I went and got some nice cream and rubbed it very gently into her pussy to sooth the pain. I had a few one night shags, but not on the same intensity as Grace had. Then we were invited to another party. I already knew this one would result in another orgy. I was fairly keen, but Grace was less enthusiastic, but relented and agreed to go. I found out why during the party. I hooked up with two women and had a great time with all the pussy a man could wish for. Then totally spent and exhausted I went looking for Grace. I found her in another bedroom with two men. One of whom was Mr big cock. I was shocked how his cock was almost turning Grace's pussy inside out as he bulled back and then pushing most of her pussy up into her own love canal. Grace was squealing as he pumped away at her pussy and his accomplice fucked her mouth. The man fucking her mouth came first and held Grace's head hard on his cock until she had swallowed his load. Then Mr big cock unloaded his load deep in Grace's pussy as as he bellowed out his coming. After Grace recovered she dressed and again Mr big cock said something like until the next time. In the car she told me that was why she wasn't keen to go as she feared he might be there. I asked why she had let him fuck her if she didn't want him to. She said that she was with just the second man and was sucking his cock and then riding him. He came in her, he and had her try to suck him back to full hardness so that he could fuck her again. With her arse up in the air she wasn't aware that Mr big cock had entered the room and before she knew it he was burying his cock into her pussy. It was too late to tell him no as he was almost fully in before she saw who was in her and his mate held her down on his cock until is mate was fully in her and plowing her pussy. After they had both cum they swapped and the thin guy had some of Grace's pussy and then I had walked in when Mr big cock was taking a second go. She complained that she didn't want to make a big fuss as that would have ruined my enjoyment. I told her she just had as although I had loved my time with the two women, Grace getting used and abused ruined any pleasure as I would never like to see her hurt. Back home I applied soothing cream for three days until she was no longer sore. I spoke with the host of the party and told how Mr big cock had hurt Grace. He had heard rumors and assured me that he was no longer welcome as was his mate. The hosts were on a much wider swinging and party scene and said they would warn everyone else and get them black flagged. After that Grace stopped seeing other men and I saw just a few more women and then also stopped. I decided to support Grace and we have been together and not swung or met anyone else since. That was nearly fifteen years ago. Better the love you have.
