“Come on, Jules,” I whispered again. “We’re too loud. Someone’s going to hear.” I don’t know why I bothered.
Soon, she was about to cum. She was really grinding my cock now. I could feel the wetness of her pussy through both of our clothes. She took her hands off the headboard and began to play with her giant tits. Her face was flushed and glistening with sweat. Her breathing was getting very short and quick. She began gasping and her whole body began shuddering. She began to cum, and it was only then that she broke her gaze from the TV and looked me in the eye. It was all too much for me.
I looked down and watched the small pearl of cum squeeze through my briefs, getting larger and larger with each burst. I pushed my hips up hard, trying my best to feel like I was cumming deep inside my sister. I grabbed her hips and pulled her down. She didn’t bother to resist me this time. It felt like I was cumming for an entire minute. She was still in the throes of her own orgasm.
Our movements died down, and there we both were. She was flushed, and still breathing heavily. Her hair was mussed and her shirt was crooked. I sat there with cum dripping down the front of my underwear.
“Jesus Christ, Jules. What was that?” I asked. I didn’t know what kind of answer I expected, but whatever it was, I didn’t get it. She stood up without a word and fixed her shirt and hair quickly. She then turned to walk out, grabbing a towel off the floor. As she walked out the door, she turned to me, threw the towel in my lap, and said:
“You better clean yourself up.”
