Back Rub for Julia

... understand. "Lay down, big bro. I want to do this for you." He laid back, and within about three seconds, Katie had straddled him. Apparently, she was in the mood for some cowgirl action. Jack definitely was not going to argue about it. His cock slid in between her thighs, and he thought that he understood what she was laughing about now. She was soaking wet. The insides of her thighs were coated with her lubrication. "Damn, K. You must have really enjoyed blowing me." She smiled down at him. She looked so innocent, so vibrant, so alive. He couldn't believe that he had waited so long to be with his sibling in this way. They could have been together like this for a year, or more, if he had only read the signs. No, that wasn't quite right. He had read the signs. He had noticed his sister's attempts at flirting with him; but he had either misinterpreted them, or discounted them as being a figment of his overactive imagination. Looking back at Katie's actions, her behavior was a clear indicator of her feelings toward him. The simple fact was that he had just been too thick headed to recognize what was going on. Katie interrupted his analysis by firmly grasping the base of his large shaft with her small hand.

Jack tried to answer, but when he went to speak, nothing escaped his lips but a hoarse moan. He just nodded at his sister. She laughed. He enjoyed banging Julia hard and all, it had really excited him; but this was heaven. "Jack." He forced his eyes to focus on his sister's face. "Just cum whenever you feel like it, sweetie." He nodded again, and closed his eyes. Some men close their eyes so that they can fantasize that they are with someone else, but that was not Jack's intention. He just wanted to feel her pussy flex on his steel hard rod without getting lost in her eyes, or focusing on how beautiful her hair was, or by getting distracted by one of a thousand other things about her. He was hyper aware of who he was actually with; and if he was never with anyone other than her ever again, he would still die a happy man. Then Katie started doing just what he had hoped for when he closed his eyes, she began to flex her vaginal muscles in rhythm with her strokes. She would slide him into her slowly, all the way inside, until his head would bump her cervix. Then she would contract her pussy, and slowly move herself upward. She called this technique "milking."
