Back Rub for Julia

... and out of her fuck hole. She chewed her bottom lip while in deep concentration, but her eyes remained locked on our scorching hot, incestuous lovemaking. "Goddammit Jack, give it to me harder. I'm about to cum!" My sister's pussy did seem to be getting tighter, and wetter. She started pushing her ass back into me faster, so I quickened my pace, and put more force into my already brutal strokes. I grabbed a fistful of her curly red locks, and pulled until her neck bent back. We were fucking so hard that our sweaty skin made loud slapping noises when our bodies met. It was lucky for both of us that Katie had an ample ass, otherwise both of us would have been black and blue from the force of our impacts. I started to feel something strange in my nether region. Usually when I am really pounding my sister's pussy, I bottom out, because I am a little longer than she is deep. This means that the head of my penis gets bumped very hard repeatedly against her cervix, causing me to become slightly numb; therefore, I become slightly less excited. Usually, slow and steady is the way to make me cum. But now, even as I felt myself to bottom out mercilessly, I began to feel strangely excited, instead of numb. Grabbing her hair must have worked for Katie, because as soon as I pulled her head back, her pussy really started clamping down on my thrusting cock. If she wasn't already cumming, then she must really be on the edge. I figured that one more thing might either push her over the edge, ...

... or at the very least would make her cum harder. I took my free hand off of her hip, drew my hand back, and slapped her ass cheek as hard as I could. There was a very satisfying smacking noise, and I knew that it must have hurt her, because my hand stung like hell. "OH FUCK," Katie cried out at the top of her lungs... and she came. Her insides went into frenzied contractions, which were in no way her usual rhythmic twitching, that were designed to milk a cock of it's semen; but these were insanely intense, and her spasms seemed to envelop her entire body. Her body seemed to seize up, from head to toe, and become rigid. If I wouldn't have been holding her close to me, she probably would have fallen. I had a simple solution to this problem, I let go of her hair, grabbed her by her waist, and pinned her body beneath mine to the SUV's seat. Her cum squirted out covering my legs, the black leather upholstery, and it even sprinkled on the ground around us. I continued to stroke into her as best as I could, but at the same time, I felt my own orgasm approaching like a runaway train. I gritted my teeth to try to keep from cumming. Katie loved the sensation of my hot cum splattering against her insides, and I knew that in her present state that she might not even notice my orgasm, let alone enjoy it. But her wild orgasm took it's toll on me, and I felt my cock begin to jerk, and I poured my hot seed into my sister's greedy belly. "Oh fucking shit, K," I moaned. I couldn't even continue ...
