My boyfriend Rob is a truck driver, he works nights and as we live quite far away from each other he picks me up occasionally if his run takes him near my home. We always make time for sex, usually when he takes his break and sometimes on the bay whilst his truck is being unloaded. The cabs in the trucks are quite big and the buks are comfortable and when you draw the curtains nobody can see in. Well on this particular night Rob picked me up and we sat and chatted on the way to his drop, the conversation was getting dirtier and dirtier and by the time we got to the bay I was dying to get my hands on his cock. The only problem was the truck was quite an old one and only had one curtain covering the bunk so I told him he would have to make do with a blow job as I was sure we would be seen if he fucked me, rob loves me sucking on his thick cock so he didn't argue and it asn't long before I had the full length of his cock in my mouth, Rob likes to pull my hair and really fuck my mouth while he tells me what a dirty little slut I am and that he's gonna shoot his load right down my throat. In no time at all I got my reward a lovely mouthfull of cum which being the good slut I am I swallowed down, then I licked any remaining spunk from Rob's cock just as he got the green light telling him his trailer was empty, we quiclky tidied ourselves up and started the journey back. As i had work the following morning I told Rob I would stay in the bunk and get some shut eye and he could wake me up when he stopped for his break, I couldn't get to sleep though so i sat up in the bunk behind Rob and stroked his chest while he drove, Rob guided my hand down to his cock so I started to rub his semi-hard on through his trousers, I could feel his cock getting harder and harder so i unzipped his trousers and took his cock out and gave him a wank, as your so high up in a truck there's little chance of being seen unless another truck overtakes you, rob told me to get on the passenger seat and turn my body towards him, I knew what he wanted as he'd purposly asked me to wear a skirt which i normally didn't do as it's really hard getting in and out of the cabs as it is. I sat opposite Rob my skirt hitched up over my thighs, giving him a glimpse of my white lacey thong I slowly stroked my inner thighs and as i started to feel horny i parted my legs wide and moved my hand up to my wet pussy, Rod told me to take my thong off and pass it to him so he could smell my pussy as he watched me playing with myself out of the corner of his eyes. Rob knows I like to be a little sub and love it when he tells me what to do, he started by telling me to rub my clit, making it stand erect, then pull my piss flaps apart so he could see how wet my pussy was, he told me to push two fingers in my sopping wet cunt then a third and then a fourth, which I dutifully did, then he told me to lick my fingers clean, he told me we were nearly at his break stop and that he really wanted to fuck my arse tonight as he thought my pussy was so wet he would barely be able to feel his cock inside me and he would need to be in my tightest hole if he was going to cum again, he told me to kneel on the floor and drape myself over the passenger seat, lift my skirt up over my bum and finger fuck my arse hole so it was lubed and stretched ready for his cock. I was bent over my face pushed into the seat as i pulled my ample arse apart with one hand and got to work on my anus with the other working my way up from one to three fingers. Rob told me we were pulling into the service station and that I was to stay exactly where i was so he could just slip himself in my gorgeous ass, little did I know that another truck had overtaken us a few miles back and the driver had got a full eyefull of my white arse being probed by my fingers. We pulled over and Rob was on me within seconds lifting me to a standing position, he grabbed my hair and pushed my face into the seat, I felt the familiar feeling of his pre cum being rubbed around my ring piece and knew that very soon my tight ass would be filled with every inch of Rob's rock hard cock. I braced myself and tried to relax as Rob rammed his cock up me making me bite my lip to stop me from screaming, Rob's pace quickened and soon he was fucking my ass for all he was worth telling me how much he loved it in my ass as it felt like fucking a virgin instead of a filthy slut who's had one too many cocks. I was so turned on I had to play with my dripping cunt while Rob butchered my arse and just as I was about to cum Rob told me to look up and smile for the guy in the next truck who was having a nice wank while he watched the slut getting her arse filled with spunk. Sure enough I looked up and the guy in the truck next to us was jerking himself off, his window was open and if it wasn't for the fact that our window was wound up I would of been able to reach out and grab his cock, I felt RTob's cock start to jerk, but just as i thought he was going to pump me full of cum he pulled his cock out and yanked my head round to face him and unloaded himself onto my face, telling me he wanted to see me take the other truckers load on my face as well, he wound down my window and pulled my hair telling me to lean across from our cab to his, the other trucker called across and said "you sure it's o.k. for me to spunk all over your misuss pretty little face Rob" Rob replied yes Dave mate like I said she loves it, maybe next time I'll let u fuck her wet pussy too, with that i felt a second load of spunk unleashed on my face, Dave wound up his window and Rob turned me round, he scooped his and Daves spunk up with his fingers and gave them me to lick clean. Then his alarm went off and his break was over, he told me what a good girl I had been and that he knew I wouldn't mind him arranging for his mate to watch as we fucked but he never thought I'd let it go as far as it did. Anyway I'll be back in the cab next week and Rob has said if he is on a similar run to dave again he will set up a meet and this time he'd like to invite Dave into the cab with us and you never know we might get some other lucky driver on his break wank over watching me getting a good seeing too...
