Back Rub for Julia

... using this technique. With the earlier excitement having driven him insane with horniness, he knew that he wouldn't last long inside of his sexy sister. After only a couple minutes, he couldn't take concentrating on these glorious sensations any longer. Jack opened his eyes, because if he didn't get a little distraction, he would probably be cumming in a matter of moments. Katie might have said that he could cum anytime, but sex just wasn't right if both partners didn't get to ride the train to "O-town." He knew how orgasmic his sister was, and he felt the way her insides were quivering after just a couple of minutes of hot cowgirl action. This position was one of Katie's favorites, because it allowed her to pick exactly what spots would be stimulated, and for how long.

Katie, for her part, felt Jack's cock flex, and the heat of his semen flooding into her belly, and immediately began her own climax. It was sudden, and violent, almost squeezing her pussy tight enough to push her sibling out. Katie fought to continue the rhythm as long as she could, but finally gave in to her own spasms, and collapsed on top of her brother satiated. They lay in a silent heap for several minutes; both of them were sweaty, and exhausted from their exertions. Katie kissed Jack's chest softly, and traced intricate patterns in his sweat with her tongue. Jack enjoyed the tickling sensations, until Katie bit down hard on the skin of his chest. "Owww!" Jack howled. "Fuck, K. What was that for?" Jack lifted his sister, and saw angry red teeth marks, on the skin just above his heart. "Sometimes women need to mark their property."
