I settled down in front of the wide screen TV to be an interested observer. Right on 3pm the door opened and Marie led the Doberman, Berny, into the r...om. Again she was naked with just her shoes and the mask. She released Berny’s lead and stood patting her pussy. Immediately Berny advanced and began to lick her pussy. Marie moaned and closed her eyes. “Yes good boy” she said, her voice showing the emotion of the moment. She quickly sat down and again Berny feasted on her delicious pussy while. When she calmed down enough to talk she said,” That was wonderful.” Then we heard a noise. We froze and then I got up and went to the door quietly, when I opened it her very hot sister meg came tumbling through the door!! “Meg!!!” Mary said in a shocked voice. When she realized what happened she tried to get to the door I grabbed her arm and pulled her to the bed. She was shocked and said,” What are you going to do? You’re not mad are you?” I sat her on the bed and I pushed her back, I. I tried to stand, but my leg simply buckled beneath me, and I landed back on my arse. Fortunately by then the excruciating pain had subsided to an agonising ache.I spied a park bench about 20 yards along the path and crawled over to it, dragging my leg as if it was broken. I managed to heave myself up onto the bench, and then must have passed out because I came to in grey daylight, with a wispy, freezing, fog enveloping me.Although it was only early October the country had been experiencing. “Bend over!”I bent over the bench, my feet on the ground, legs spread two feet, ass pointing up, waist down, my chest, face, arms resting on the bench.“I want you to fuck me as hard as you can, make me scream” I demanded.Trevor grabbed my soft narrow waist with his strong calloused contractor hands, he had a strong grip.I wouldn’t be able to escape that grip even if I wanted to, which made me feel dominated by a strong man, to serve his needs, making me feel like a slave woman serving his.
