I am fully bisexual and versatile, i.e. I get fucked and fuck other guys.  My wife knows and I meet other guys from time to time for sex. We also have guys, white and black as long as they have big cocks to fuck my wife and if they are bi, me as well.  Bisexual My friend, Andy, who I had known for some years had a van with a converted back that he could make into a bed. We would meet each other at a dogging site with the hope of finding other males or couples for sex. If we did not get lucky then we would have sex with each other, either in the woods or his van. I would often suck his cock which was always rock hard and about the same length as mine 7", however his was very thick and about 6" around. After sucking him for a while, we would swap and he would swallow my cock taking me as deep as he could. Once we were both rock hard, we would fuck. As we both liked to give and take cock, we would often swap around. However, if we were outside, I would tend to fuck him as our height difference made it easier, but not always. He would just drop his Jean’s; he was always commando. I would then lube us both up and gently ease my cock into his hole. Slowly building up a rhythm, I often found it difficult to cum, so would often pull out and wank off with him. I on the other hand loved being naked outside, so on a warm summers evening, I would often strip naked and bend over a log or hold onto a tree. I would lube up my hole, he would open me up a bit with his fingers, trying to stretch my arse for what was to come. Then I would brace myself as he would gently slide his cock head in, remember this was over 6" around. This would always be painful as he was so big. Once the head was in, he would slowly work his cock in and out of my arse gradually going deeper and deeper. It would take a few minutes of this and me trying to relax my sphincter muscle for me to take all 7" and for the pain to subside. Then the pleasure would take over, that lovely feeling of being all full up. He could then fuck me deep and hard. If we decided to use the van, often he would lay on the mattress and I would ride him. This was probably my favourite position to get fucked as I could control things. It also meant he could wank my hard cock whilst I bounced my stretched arse up and down. Sometimes, I would try and cum like this shooting my spunk over his stomach. Once I had cum, I would dismount and he would wank himself off, cumming and adding his spunk to the pool of my own, while I gently squeezed his balls. Threesome My friend, Andy and I would often talk about our experiences, he mostly liked meeting couples where the husband wanted his wife fucked by other men. I would also tell him about my wife and I meeting other couples, but mostly men, especially black guys with big cocks. I showed him some pictures of my wife dressed in stockings, bra and panties, also some of her taking black cock. At the time these pictures were only on a small 1”x2" screen of my camera, before smart phones existed. He said he would love to fuck her. I was not sure she would go for him as he was a down to earth builder, a nice guy but a bit rough and ready. He also smoked, which I knew would be a no, no. Anyway, I said if I could take a few pictures of his face and hard cock, I would see what I could do. If we met though he would have to refrain from smoking so that she would not smell it on him. He said he could do that as he wanted to cut down anyway. I mentioned it to my wife and showed her the pictures. Although not keen on the smoking, she surprisingly quite fancied him. I think she liked the idea of a rough, strong 6'6"" builder as a change from me and the more professional types she had generally insisted on. We invited him round to our house for a drink and a chat, not necessarily expecting anything sexual to happen on the first night. My wife, Liz, as usual was all clean, shaved and beautifully made up. When we had started swinging, she had been reluctant to shave her pussy smooth and I would often do it for her, leaving a little tuft at the top of her slit. By now though I had convinced her to let me shave it all off and would do it regularly. She wore lovely red and black lacy underwired bra and knickers with a matching suspender belt and black stockings. Over this she wore a red halter neck wrap around dress, that would split, when she sat down to show her lovely slim legs, with the occasional glimpse of black and red lacy stocking top. I had asked Liz, to sit on the sofa, and invited my friend, Andy, to sit beside her. I got some drinks and we all chatted. Andy was very good and complimented Liz although, he did tend to swear quite a bit while telling some of the stories of his experiences. At one-point Andy went to the toilet, so I asked Liz what she thought and was she up for playing. She said yes, she liked him and wanted things to progress. When Andy returned, she moved closer and let the split in her skirt open showing all of her leg. Andy was not slow and moved his hand to stroke her leg, then moved in to kiss her. Things moved quickly after that and Andy undid the bow at her waist that was holding her dress together. Opening her dress, he squeezed her 34DD boobs and started kissing her neck. This always makes her swoon and she was soon taking his top off and stoking his chest. Andy moved his hand down and inside her knickers, all the time kissing her mouth, neck and now her boob. He soon had her dress off and her bra, allowing him to suck her nipples. Liz was trying to get his Jean's open and managed to extract his hard cock. Grasping it with both hands, she pushed him back and slid down until she could lick the huge head and then suck him. Given his size she could barely get the head in her mouth. This continued for a few minutes, then Andy moved her so that she was half laying on the sofa with one leg on the floor. Andy moved between her legs and started licking her pussy and clit. I had let Andy know previously in our conversations what Liz liked and he was doing all the right things. I in the meantime, got undressed and in between wanking my cock was taking a few pictures. After about 5mins of licking Liz's pussy, Andy moved up so that his rock-hard cock was next to her pussy. I think she thought he was going to enter her as he pulled her around so her arse was on the edge of the sofa. What he did was new to me, he took hold of his cock and put the head just inside her wet pussy lips, then rubbed the head up and down very fast with his hand. This made her cum very fast and squirt, like I would do with my fingers on her G spot. Once she had cum and everywhere was wet, he pushed his cock right in and kept her cumming by fucking her hard and fast. I was right beside him kneeling on the floor with my hand on his arse urging him on. After a few minutes he paused and I suggested we adjourn to the bedroom. Where we resumed, he licked up her juices before fucking her again. This time I got behind him and after licking his arse hole to get him wet, rubbed my hard cock up and down his crack whilst he was fucking and kissing Liz. We then swapped around and got Liz kneeling. Andy got in front so she could suck him and I fucked her from behind. We had now been fucking her for about an hour and a half, so I decided to let myself cum, filling her cunt with my spunk. Liz collapsed on the bed, so Andy turned her over and licked her pussy and clit, making her cum again and sucking all my spunk out. She then decided to get on top of Andy and ride his cock and with him pushing up into her, they both came again, Liz first and then Andy. At this point we all rested, I went and made coffee while they sat and chatted on the bed. I could hear Liz giggling from downstairs and thought how well the evening had gone. Since then we have met regularly, sometimes Andy will pick her up and take her out in his van. They will go for a drink in a country pub as a couple, then he will take her somewhere quiet in the country. Sometimes if the weather is nice, he will have her outside laying on the grass or bent over a tree branch. Other times it will be in the van. Each time they will take a picture or two and send them too me. He will always give her a good fucking and then send her back with a cream pie for me.  When she arrives home, I like to have her kneel over my face so I can lick her out, while she relates in detail what they have been doing, then I will have her and fill her with spunk again. Other times we will just have a threesome and either I will fuck him while he fucks Liz or the other way round. If we got the chance, we would both fuck her cunt at the same time and all try to cum at the same time and we will both get down there to clean her and each other up as we both like cum. Andy knew I would like to DP Liz and sometimes he would give her a massage with some cream or oil. Eventually working down to her arse, I would add some lube and he would work his fingers into her, letting me know how many he had in her. All to no avail, she would pull away if he got his cock anywhere near her arse. We did very successfully try DVP her, both in her cunt, she would often ride his cock and lean down to kiss him. I would come up behind and with some lube on my cock push in alongside his cock and he remember was 6" around. This would really stretch Liz, which she loved. We all enjoyed it a lot, I would often cum first and then let them finish. We tried that several times, the best one was when Andy and I kept still and he helped push Liz back and forth on our cocks. We actually managed to all cum together, a fantastic achievement, sadly never to be repeated. Liz was a big squirter, if I could convince her to let go. She was always frightened of the mess she would make on the bed. I would ensure she was on a couple of towels often Andy or I would hold her arms out of the way so that she could not stop us. Then one of us would work her "G" spot, either me with two fingers or Andy with his cock head, until she would cum squirting all over the three of us. I have had her juices hit my face and I would be three feet above her. Like all good things, it ran its course and after about 7 years, Andy was the only one we were seeing but not regularly. He came round one evening and was very course in his language and manner, Liz felt she was just being used and that was the end. It was great fun while it lasted.
