We’d spent a very plaesant afternoon/evening at a friends barbecue. I was driving and Donna had spent the time drinking and flirting. She was very frisky and kept coming over and pinching my arse. We left there around ten pm and as I drove home she moved her hand onto my crotch and gently rubbed my stiffening cock. “Lets stop off somewhere for some fun” she suggested so I diverted to one of our favourite dogging spots but there was no one there. I drove the short distance home with a frustrated Donna who was sat in silence pouting.She went upstairs to change and came down in her favourite dogging dress and heels. “Come on lets go find someone to have fun with”I nipped up and changed and we were back in the car touring the local spots for action. I soon realised we’d have to go further afield and she agreed so we set off. She pulled the top down as I drove and I pulled up by a few trucks so they’d get a look at her. She was giggling a lot so I knew they’d seen her. I had to pull past the one truck as someone wanted to pass us and she told me to u turn at the roundabout and go back to finish the show off to one particular trucker so I did.As we were approaching him to pass him he indicated he was pulling into a large layby ahead. “Follow him in” Donna said so I tucked in behind him and we parked right in front of his truck. She got out and waved to the trucker who waved back. I got out and walked to the back of the car and leant on the bootlid. Donna came over and firstly rubbed my by now hard cock then freed it and was gently wanking it. The trucker who we found out later was called Mick stood and watched. He was early thirties and was really slim and muscular. She stood facing me then bent over letting the dress ride up showing her perky ass.Though it was quite dark the trucker had left his side lights on so we were quite well lit up. We were hidden from the road by a nice tall hedge so no one could see unless tehy came over. There were a couple of other trucks there but no sign of any other men.Mick was staring at her ass as she bent right over and started to gently suck my cock. I motioned to him that he was ok to come over for a feel and he moved right behind her and slipped a hand between her thighs and gently fingered her wet cunt. I could feel her push back on him as he moved his fingers up her. She put her hand between her legs and rubbed his cock.He looked at me and said “Back in a second”. He nipped back to his truck and came out with a condom. He got his cock out and slid on the condom. He moved behind her and pushed his cock up her. It was a very nice cock. About 7 inch and thick. She moaned quietly as he pumped into her. He got more confident when she was telling him to “fuck me hard!”. “COME ON FUCK ME HARDER. HARDER!”He roughly pulled down the dress top and was really grabbing and squeezing her tits. As he pumped away at her I noticed someone was watching. One of the truckers from another wagon had heard all the commotion and had come out to watch. He rubbed his cock and watched a trucker fucking some half naked slut while sucking off someone.Mick was by now nearly going to cum he grabbed her thighs and punded as deep as he could then shot his load.Donna was panting and had also cum. She paused sucking my cock as Mick moved away. The other trucker moved closer. He was a much older man. Early sixties maybe. Very much overweight. He had by now got his cock out and was wanking. He looked at Mick and Mick gave him a condom. Her thanked Mick and smiled as he came over. He got the condom on and moved behind Donna. He grabbed her by the thighs and slid his cock inside her. This surprised Donna as she had no idea there was someone else there.The new man, more confident that he could treat her a bit rough fucked her hard from the off. He spanked her arse hard and asked her in a hissing voice, “Do you like that? I bet you fucking do” . “She was trying to suck my cock but had to pause so she could yelp slightly as he spanked her. He was having none of it. “Suck that cock you dirty slag I want him to fill that mouth with cum” I grabbed hold of the back of her head and pulled her onto my rock hard cock and mouth fucked her. I only paused when she was nearly choking then I started again. He garbbed her thighs and I found out later had pushed the thumb of his left hand up her arse. He was spanking her with the other one. I couldn’t hold back any longer and shot my load down her throat. Seconds later the man fucking her came. He moved back and dress. He thanked us and walked away back to his truck. Donna was panting and as she stood up i could she she’d spilt half my cum down her face and tits.I made her get in the car and I drove her home on display covered in cum. I made her walk to the house from the car like it too. Dirty slag loved it.
