a slave melts to her hands and knees, keeping her back straight, head raised, eyes looking straight ahead. Spread your thighs widely, raising your buttocks into the air

quotes

He knelt me there. "Put your head down, to the floor," he said. "Clasp your hands, firmly, behind the back of your neck." "Yes, Master," I moaned. He was then behind me. He put his hands, under my arms, on my breasts, sweetly and firmly. Then he moved his hands back, caressing my flanks. My head was down. My fingers were together, behind the back of my neck. I was in his collar. It was steel, I could not remove it. I belonged to him. My body hurt, from his whip, that of my master. My head hurt, from my hair, where I had been conducted, unceremoniously, to this location. "Please, Master," I sobbed. "Not like this! Not you, please!" "The slave is pretty," he remarked. "Oh!" I cried. "Oh!" "You have a lovely ass," he said. "Ohhh!" I said. "You may thank me," he said.
