I asked her if something was wrong. Her reply was a surprise to me. “I haven’t had a good orgasm in a while, and the vibration of the truck is exc...ting me.” I asked her if she wanted me to pull over and help her with that problem, she gave me a shy smile, and I knew the answer. Turning off into a road side park, I closed the curtains on the cab to give us some privacy, and stepped into the sleeper with her. In no time, her clothes were off. Her freshly shaven pussy was glistening with her. It was too much and I orgasmed again. I really was becoming a real slut, and I loved it.He finished, but did not release me till he had stuck a butt plug up my arse. I knew what was coming next, because up till now he had only shared me with Steve. He untied the ropes.“Go to Steve and let him finish you off. You may take the car, but do not wear anything else.I stood up and with the slightly unstable step you get with a butt plug up your arse moved out to the car. I drove to Steve’s shop,. ” I was totally gone. I went completely limp and gave myself over to the waves of doggy pleasure until Rex finally stopped, panting almost as hard I was.“Just stay still till the knot comes out and he will walk away but stay there, don’t get up. It’s my turn, I fancy some doggy sloppy seconds.”“Please Sir please let me get up I am shattered.”“Just do as your told doggy bitch.”I couldn’t really deny that name could I. I had just freely given myself to a dog. Begging it to fuck me even harder.. She milked the last few drops and offered her fingers to my mouth which I duly licked clean. ‘Good boy’ she said kissing me on the lips gently. ‘Hmm you taste good, no wonder you ate in all up’. She gave my ass a squeeze and walked out.I looked at the mirror, covered in my cum, panties now around my ankles and wondered, what the hell just happened!? I pulled up the panties and put my clothes back on, not even trying the new stuff on I bundled it all up and headed back to the shop floor leaving.
