I ventured back to my local park to meet up with Dave and Clare this week for some more open air sex. I wore a t-shirt and jogging pants, no pants and trainers. My wife Sue knew where I was going but did not feel she had the bottle to do it just now. She was open to the idea of having sex with another male and me. She was comfortable with me going off and fucking another woman. I got to the wooded area and went down the path, as I approached the area from last week I could see they were already there. I then saw Clare was naked on her knees giving a blow job to another bloke, also naked. Dave was naked and putting a blanket on the ground. I joined them and stripped off. I walked over to Clare and the other bloke and offered her my semi erect prick. She then took it in turns sucking us both. She then got up and went over to the blanket and got on all fours. Dave handed the bloke a condom. He put it on and got down behind Clare and entered her. As he fucked her I Knelt beside her and played with her tits, especially her swollen nipples. The bloke fucking her lasted about 5 minutes and came as he fucked her. He pulled out, pulled off his condom full of spunk, thanked them, gathered his clothes up and left. I then laid on my back on the blanket and Clare rolled a condom onto my 8 inch erection. She then lowered herself onto my prick and rode me. It then started to rain, with thunder and lighting. As we were in the woods we all thought we should pack up and go, to be on the safe side. I then suggested to them we could continue at my house a few minutes away. I told them my wife wouldn’t mind. I secretly thought it would be a good way to spring it on Sue and get her to join in in our own house. We dressed and they followed me to my house. We arrived, soaked to the skin. Sue let us in and I introduced everyone. Sue directed everyone to our conservatory and told everyone to take their clothes off. She said she would wash and dry them. The three of us stripped off and stood naked in front of Sue. I could see she was looking at Dave’s penis which was flaccid at 6 inches and he was shaved smooth. Sue said she would get us some clothes, but Dave told her not to bother as he was comfortable being naked. Sue took all our clothes and went to the utility room. Dave commented on Sue’s figure and large bust. Sue returned and told us to use the downstairs shower to freshen up. Dave then asked Sue if she was going to join us. To my amazement she said she would. She then went with Dave to the shower room. Clare walked over to me and started to wank my prick and asked if Sue was into women. I told her in all our years of marriage she never suggested she wanted to try being with a women. I was now fully hard and fingered Clare, rubbing her clit and finger fucking her. After a couple of minutes we headed to the shower room. As we entered I saw Sue naked in the shower with Dave. His prick was rock hard as he was soaping Sue’s body, paying particular attention to her tits. She then soaped his prick and balls, wanking him. They then kissed passionately. Clare got on her knees and sucked my hard prick, licking me up and down my shaft and licking my balls. Dave and Sue got out of the shower, so Clare and myself got in and washed each other. Dave and Sue dried each other, then he turned her around and bent her over and slipped his prick into her pussy and proceeded to fuck her. Sue was moaning with delight. Clare and I got out of the shower, dried and I bent her over and fucked her from behind. After 5 minutes of fucking I suggested we go up to our bedroom and continue there. We all got on our king size bed. Dave and Clare were kissing and fondling each other, while I was kissing and sucking Sue’s swollen nipples. Clare got on her back and Dave got between her legs and fucked her. He reached over and fondled Sue’s right tit. I moved over and eased my prick into Clare’s mouth. Sue then got on all fours and offered her arse to Dave. He slipped his finger into her pussy, then moved it into her arse hole. Sue was moaning with delight, she likes a bit of anal. Dave pulled out of Clare and started to fuck Sue from behind. I moved across and offered her my prick. She was now having her first spit roast. Dave was fucking her hard and she came with a loud shout. I then moved over to Clare and got between her legs and sucked her pussy and clit. She came after 5 minutes of me licking her clit. Dave was still fucking Sue and slapping her arse cheeks. He then pulled out and came in several spurts over her back. Clare knelt up and wanked me. As I came, she opened her mouth and took most of my cum in her mouth. She then moved over to Sue and kissed her. This was first for both of us seeing her kiss another female. As they kissed, Sue took some of my cum into her mouth. They kissed and felt each others tits and pussy. Both Dave and I watched the show, wanking our pricks. When they finished, we all showered and stayed naked. Dave and Clare accepted our offer of staying for something to eat and stay the night. During the evening both girls were fondled and fingered by Dave and myself keeping our pricks hard. At night Sue went with Dave into another bedroom for the night and I spent the night with Clare. During the night I fucked Clare twice and brought her off twice. I could also hear Sue being fucked for most of the night. After breakfast and they had left Sue told me she had been fucked in her pussy 3 times and twice in the arse and had 5 orgasms. We have exchanged phone numbers to meet again at their house for some fun. Sue now wants to go to a club or arrange for either a couple of couples to come to our house or even 2 or 3 men so she can try a gangbang. She is a changed woman. We now have sex every day, sometime twice. She has become a right old nympho.
