This was the first time I ever looked at her with lust. She was gorgeous and even cuter than thatat this very point in time. I gathered my thoughts as...she gathered herself and I told her she should get into her pajamas. She stumbled to her dresser and opened it and I turned to leave the room. That's when she said you dont have to go, I'm your sister, we are best friends and we dont have shit to hide from each other. I agreed and then asked if she was interested in a glass of water or another. A horizontal wooden rail, about four inches in diameter, was fixed between the posts at waist height and Jill was positioned standing with her belly button pressed against it. The old man was kneeling by her side. "This is my favourite bit!" he said to anyone, "Come on cunty, spread 'em!" Her ankles were pulled apart and tied to the uprights with thin rope.The old man then pushed himself painfully to his feet and moved around to her front were he took her wrists in one hand and placed the loop. She kept on, "I want to feel my daddy's spunk splashing hot in his little girls cunt." With that she pushed her (now) cunt down to envelope all of his maleness. Susan then sat back upright and started hunching her pelvis forward and back on it, grunting with each bottoming out. She started speeding up and hunching harder. As roughly as she was using his cock it almost hurt. It kept him from cumming as soon as he was afraid he was going to. Watching her tossing her head back and forth, her. Within a few minutes I gave up a fair bit into the dog bowl. Thinking that was the end of the session he now ordered me to lick the bowl clean. Then he said that he would leave it there. Just as he had said that there was a knock at the door and it was his neighbour. I was told to get into the shoulders down arse in the air position whilst he let him in. I was a bit unsure of this but stuck with the idea that he was of a similar ilk and not to worry. Up he came to the room and just nonchalontly.
