A Back Rub For Julia Ch. 06

... began wiggling her ass invitingly. Sister or not, she was the most beautiful woman that I had ever seen. She rested her face against the bed, so that she could use both hands to spread her ass cheeks. She arched her back, exposing her dripping wet snatch to me. I required no further encouragement. My boxers hit the floor in record time. I knew what she needed. She wanted to be fucked as hard as I could manage. My sister liked pain, and while I wasn't overly experienced in rough sex, I was a quick study. I positioned myself behind my erotically posed sibling, and grabbed her roughly by the pink belt that she wore. I aligned myself with the entrance to her slick tunnel, and used the belt to slam her roughly against me, impaling her on my cock in one swift stroke. The almost instantaneous filling of her tight little pussy with my thick prick made her scream into my mattress. Luckily, my parent's bedroom is at the other end of the house, so her muffled cry probably wouldn't be heard by them. I bottomed out inside her violently with over two inches of man meat sticking out of her passion fruit. I hit bottom inside her so hard that my tip went numb.

I continued to stuff her muff as best as I could during her orgasm, because I knew that continued pumping would only increase her pleasure. It was a long, hard orgasm; and when it stopped I paused outside her to give us both a break. "God, Jack. You make me feel like such a filthy slut." I didn't exactly know how to respond to this. "I'm sorry Katie. I didn't mean to..." "Don't be silly, big bro." She interrupted me with a chuckle. "I just meant that you make me want to be extra slutty for you." She peeked around at me, her eyes were riveted to mine. "You know that I'd do anything for you, baby." She paused, and her eyes sparkled extra bright in the moonlight that steamed in through my window. "Do you want to fuck my ass?" She smiled, and wiggled her ass teasingly. "C'mon Jack.
