August bank holiday Monday and the alarm went off at six am. I looked out of the window to see heavy rain. Im playing golf in a charity day and its a 2 hour drive. I had a long hot shower, dressed and left the house with plenty of time to get there. The roads were terrible, the motorway had standing water so i kept the speed down to a steady 60/70 and decided to skip breakfast on the way and grab a sandwhich in the club house when I got there. An hour into the journey I took a call to be told the day was cancelled due to weather. I reset sat nav for home went to the next roundabout and started journey home. Its now a typical Bank Holiday, Pissing down with rain and im stuck behind a caravan with visibility reduced there was no way to overtake. A few minutes later there is a load of sparks and the caravan slows to a crawl, indicates left and pulls into a layby, I overtook, looked in the mirror and thought they may need help so pulled into the layby exit, revearsed back and got out the car. You ok mate I said, I know sod all about cars but can offer a lift or use my phone if its any use. The guy looked at me and said thanks mate not many people would offer that now days especially when its pissing down, had a problem with the exsaust when we left, did a bodge job to get us home but looks like I need to do it again and its no fun in this weather. He opened the door of the caravan and had some bits and bobs there to do the job with. His wife then walked down the side under her umbrella and said will it take long Dave, about half an hour love he said. I offered to stay and help and Kathy said Ill put kettle on then. We got started, I really know sod all about motors but I held the pipe, passed bits, cut wire passed tape and all the time was soaked to the skin. I then smelt bacon, put my head through the door to see Kathy cooking bacon, that smells lovely I said, she said you are soaked ill get you a towel, Dave then came to the door, all done I think it will get us home now and Kathy passed us both a towel and said get in out the weather. I sat down and started on the bacon sandwich with both of them. Dave you need to get out them wet clothes have you got a change of clothes she asked me. I did in the car so she suggested I get them and dry off in the caravan and get changed. I grabed the coathanger hanging in the back of the car, walked down the side of the caravan, through the door to be greeted by Dave completely naked with Kathy rubbing him with a towel. Come on mate get you stuff off and Kathy will give you a rub down with the towel to say thanks. I started to get undressed and turned to see Kathy standing in front of Dave when she said your getting hard Dave does that want rubbing to, Dave said we have a guest now see to him first. She walked over to me, wearing a sweat top and jeans, early fifties, quite slim and attractive. My head was in a bit of a whirl as I stood there in a wet polo shirt and a pair of wet underpants. Theyl both need to come off she said as she pulled my shirt over my head, droped it to the floor and then pushed down my pants, leant in to me and said now both of you are a bit hard, looks like my lucky morning Dave and started to kiss me, I heard the door shut and lock. I looked over to Dave who said you OK with this, I said think so as Kathy put her round my cock and started to slowly rub up and down and then kissed me again. Her tounge probed into my mouth and I responded with the same. She broke away and guided me to the sofa. We both sat on the sofa kissing while she fondled my hard on, she then took my hand and guided it to the button on her jeans. I undid the button, slid down the zip and i eased her jeans apart putting my hand down the front of her panties and feeling her warm wet pussy. I played with her clit and she moaned and breathed heavy breaking away from the kiss putting her head now on my chest and licking and sucking at my nipple. We carried on. I looked over at Dave he was leaning against a wall unit looking down at Kathy and playing with his hard cock. Kathy said we should all be naked, jumped up and undressed very quickly. She lay on the sofa, opened her legs and said lick me Stu. I was on my knees and licking her. My god I was as horny as hell now but nothing prepared me for what happened next. As I looked up I saw Dave walk over and put his cock into Kathys mouth I couldn’t believe how fantastic this was. Many will have seen this, but it was my first time, I had fantasised about it but now it was happening and it was everything I thought it would be, and more. I am 100% straight and had often wondered how I would be with another guy, the answer was as horny as hell to the point if Kathy had been able to touch my throbbing cock at that moment it would have been all over and very messy. I was licking and watching Kathy useing her mouth and tounge on Daves cock when she stopped sucking, threw her head to the other side, I felt her body stiffen and vibrate as she had her orgasm, She used the word fuck several times as she peaked and I had to do everything to stop my self from joining her. Dave taped me on the shoulder, your turn mate, I stood up and we changed places, Dave crouched in front of her and slid his cock inside her and started to fuck her slowly, Kathy groaned and moaned while reaching over to my hard cock with her hand she fondled me and then pulled me over to her mouth where she started to lick and suck me just as she came again. Dave carried on and I was now doing everything not to spoil it, my balls were aching and it was becoming almost impossible to stop my self from shooting in her mouth when she came again and so did Dave, shuddering he was filling Kathys pussy full of cum and I Christ me to, Kathy knew and took me fully in her mouth where I came and came. Kathy swallowed, liked my cock as more came and took me back into her mouth again. I cant remember the last time I came like that, it was huge. I sat back against the table, laughed a little and said fucking wow that was special. I grabed the towel again and wiped my self as Dave did the same. Kathy sat up and said I don’t think any of us was expecting that was we. I said youve obviously done this before though havnt you. Lots of times said Kathy but when its unexpected like that and not planed it can be very exciting. We had a another coffee exchanged telephone numbers and I left. I am really looking forward to visiting them both again. So after years of looking for a like minded partner to swing with, it took a wet bank holiday Monday to break my cherry on the swinging with my first 3some. Now looking forward to the next......................and will be working hard to find a like minded lady friend to join me.
