Plans for threesome

My girlfriend and I have been together for 18 years and have recently decided we want to tie the knot on our relationship and get married.

10 years ago I told her that I wanted her to feel free in our relationship and that she was allowed to find a second lover. She didn't hesitate and found a ecurity guard who was more than willing to fill her up on a regular basis. She would leave the house every tuesday at 8.30 and go to his place where he would use her and pump his junk into her pussy. She'd come back all limp and tired but satisfied. Tis went on for about 4 or 5 months and she told me that every time she went there he would bang her 3 or 4 times until he burst inside her. The first time she came home I was shaking with the adrenalin. She came over to me and kissed me and said well it happened.

I asked her what it was like and she replied that it felt right and that she would be seeing him regularly from there on in. I lifted her skirt and pulled doen her skimpy pantied and as soon as the gusset came away from her crotch I could see her swollen lips and knew she'd been used and abused by a much larger cock than mine. I bent her over the arm of the sofa and as I pulled my pants down she said "he's still in there you know" as I pulled her lips apart his remnants bubbled and dribbled out so I plugged the flow and fucked her already obviously well fucked pussy until I delivered her fourth or fifth load of the night. She told me a couple of days ago that he used to pay her so my innocent and shy (or so I thought) girlfriend was actually somewhat of a whore, now that was a turn on.

About 8 years ago I was unfaithful to her and couldn't stand the guilt I felt, so I told her about my infidelity and we split up for a few months, but still lived in the same house as it was financialy beneficial and we still had a good friendship. During those few months she started seeing my friend who would come around 'often' and take care of business with her. He'd sit and watch tv with us both until I gave in and went to bed. They would get up to allsorts while I was in bed and I could hear every word and noise that was made as my room was directly above the living room where they were. Their sex sessions would last hours and I was quite jealous that I wasn't involved as I still loved her. Their brief relationship came to an end when his ex girlfriend wanted him back and he ran to her. After a few weeks we reconciled and our relationship has grown passed all the bad history. She recently told me that she only fucked him to get back at me and knew all along that I could hear what they were doing.

Recently, after a heavy night of drinking and while in the throws of an intense sexual session my girlfriend stated that she would like a threesome. I was quite surprised by this and asked her why she wanted one. She said that her libido had returned with a vengeance after starting a course of medication and that she was constantly horny. I asked her whether she wanted mmf or ffm and she said she wanted another cock in the mix. My eyes lit up. It has been a long standing fantasy of mine to see her being fucked and completely used by another guy since hearing her banging my friend all those years ago. When I asked who she wanted it to be it came as no surprise when my friends name came up again. Needless to say I was so turned on by this that I blew my nuts into her. That night was the most intense of any I've ever had and we'd only talked about the situation briefly. Since then we have chatted about it and have spoken to my friend who has agreed to give it a go as long as don't hold him accountable for any negative effect on our relationship.

My girlfriend has since been in constant contact with him and tonight he is coming around with a the view of having some drinks and then getting it on with her. I am so horny recently that my cock hurts as it hasn't been flacid for more than 30 minutes since we asked him.

She has told me what she wants to happen and her plan sounds great. When we come in from the pub she will go to the bedroom and get changed into something sexy, then she'll come down to us and we'll play truth or dare and she wants me to dare her to give him a blow job in front of me. Then once he's sufficiently turned on she'll take him upstairs and I have to stay downstairs for at least half an hour so that they can get settled together. She then wants me to enter the room and join in. Her words to me were "If I'm not too sore to walk in the morning you haven't fucked me hard enough", I don't think we'll have a problem making her sore though. I have plans to keep her up all night taking turns to use her and enjoy every orifice.

I'll update this story once it's happened and report whether I found it as good as I think it will be or whether the wedding is off.
