My wife and I have always had an open relationship, even before our wedding. We have always had sex with other partners, some that we knew before we met and some newer ones. While we often fantasised about her having two guys at once, she never had, she thought she wouldn`t be able to handle it and felt she might get a bit sore. We did agree however that if she ever changed her mind then it would be me and one of her lovers. Definitely NOT two other guys , she used to go out regularly for meets with her men friends and I went to meet ladies...always only one to one sex, and we always told each other what had happened. She obvviously had more lovers than me, but that is usually the way in these rtelationships, but it was fine by me and she is very choosy so she wasn`t out a lot. Last week was different, she went out to meet a regular lover, Kev. She got home and told me that when she got there Kev`s cousin Alan was at the flat as well, Kev said it was a surprise for her and they were both gong to have her. Oh no your not she said, one thing is that she shouldn`t be taken for granted and two we had a strict rule about threesomes. Anyway, they had a drink and she agreed that Alan could watch her and Kev and maybe wank off at a distance. This was Ok by them both, so she and Kev got down to business..apparently it was their usual kind of stuff.she sucked him..he fingered her.......they 69`d for a while then the vibrators came out..this was pretty standard stuff for them both. She always gets really aroused with vibraters and sucks cock like a demon while she is getting stuffed with one. She said she was happily sucking Kev while he vibed her pussy.she was getting so into it that she was drifting into her first orgasm and was forgetting she had an audience.Then she became aware that Alan had got closer and was wanking himself and rubbing her nipples with the slimy end of his cock. She started to think about pushing him away but thought it wasn`t really a big deal. She had a fantastic orgasm and got Kev to fuck her while she was still recovering, not wanting the feeling to subside, he started to screw her slowly but she wanted it hard so he rammed into her while she groaned with pleasure then she felt her hand being tugged towards Alan.She said that she felt the urge to wank it so started to pull on him while Kev fucked her hard and told her that she really wanted two cocks...she said that was when she realised he was right..but where was I............she tried to resist the feeling, but the urge became so intense that she either had to stop and come home to me or give in.........well the opportunity was there and Alan was quite good looking.she said she fought the urge but eventually turned her head to take Alans cock in her mouth. She tells me that the feeling of being stuffed at both ends was amazing..she had a fleeting feeling that sdhe wanted to share this experience with me, but her horny side got the better of her and she gave in completely. Apparently she was fucked by them both, got a pussy full of Alans spunk and Kev came on her tits while she sucked Alan back to hardness. They both took her again inspitroast style and sent her home to tell me all about it. She had to go to a bar full of spunk with it running down her thighs, to get up the courage to tell me. At first I was appalled that she had done this without me, but she started to cry, and I felt awful , in the end we decided that it had been good because she enjoyed it so much and no harm was done. Now the best thing is that she knows what she can handle and we have group sessions regularly now...the best was when Alan and Kev came round and all four of us had a fantastic night.
