I had been away for 9 days on a training course in edinburgh,accompanied by my colleague Jo. We are both mid 30's fit and married, but had enjoyed 9 days away from home with new people and all the mild flirting that goes on.As it was a beautiful day i decided to go home the pretty way, down the A702 to meet the M74 then onto Chester.I am lucky as my company car is a convertible, so top down and away. After about 15 miles we stopped at some roadworks, and I heard some flattering comments comong from the van behnd us, from the drivers window I saw a pretty face and Jo who had been havind a converstion with them shout " If you can catch us , you can have us" fortunately the lights changed and the van soon become a dot in the rearview mirror. We laughed and the miles increased, and i forgot Jo's offer until we can across another set of roadworks. We waited there for what seemed hour and to my horror the van became a larger dot in the mirror again. " What did say" the pretty face shouted to Jo ," If you catch us you can have us" again my luck was in and the lights changed again. soon the signpost we saying M74, 3 miles. But within sight of the junction yet another set of lights and we waited. The van caught us up and the prtty face got out and came up to us. he was early 20's very fit, he smile and said" I caught you twice now can I claim my reward " I nervously looked at Jo who smiled and said " If you catch us a third time OK" Again the lights changed and we were on our way. we stopped for coffee on the M6 about 2 hours later and to my horror as we came back the car "the van" was parked next to it with the boy sitting on the bonnet. " can i have the reward please" I noticed the van was infact a camper van with trailer, but Jo didn't and said " OK where would you like US" Before i could say anything the side door of the camper opened and 3 more faces appeared " In here" they shouted. Jo pushed me in and I heard he say " Come on this is going to be FUN" After about an hour I emerged from the van, after being fucked by 4 men while watching them all fuck Jo who laid alongside in the campervan bed. There had been a gangbang in the service station car park and only we knew about it. My pussy ached, my throat sore from sucking. When i got home hubby said did I have a good time andI said "yes"
