I was happy as her lovely boobs bounced as she ran around the block. Seeing me, Ben the name, she twisted her ankle on the footpath.I ran out and help...her into my garage and got her to lay down on a towel and put her foot on a chair. I iced the ankle then noticed she had dislocated it. Mentioning the dislocation, I asked if the running track pants were new or old. She advised very new. I told her the ankle was swelling and the hospital would cut them off her. She looked at me in concern. Cathy. She played with the grass, oblivious to her surroundings. Hearing the warning bell before lunch, she got up and headed for the locker room. She opened her gray locker and began removing her gym clothes placing them in a plastic bag. She was looking in her locker when another girls voice rang out."Her brother is so fine!" the girl said to whomever she was talking to.Kailynn couldn't help but feel a twinge of jealousy."His muscles are so BIG!, I wonder if he's BIG ALL over?" another voice said.. I moved up to those awesome breasts, rubbing underneath them knowing this is one of her pleasure "spots" , the soft moans begin anew. I take those wonderful orbs firmly in each hand as I begin to rise. Now fully upright with my hard cock dancing on your tummy I drew her to me, pressing my lips to hers , immediately we were drowning in passion our tongues twisting and twirling as if for the last time. My rigid cock throbs against her, begging for release.As she pulled away slightly, " I love. I opened my eyes, lying in bed with my little sister curled up against me, her soft permed hair on my chest and neck. I shook her a bit and she looked up at me, a cute smile spread across her face, then a flash of worry, "What time is it?" Quarter after seven. Mom just called us for breakfast."She quickly sat up and tossed the sheets off her, I put my hands behind my head and watched her petite frame as she got out of my bed wearing only a yellow t-shirt and looked for her panties. She slipped.
