I get to my door and there is a "Don't Disturb" tag hanging on the knob. Key to lock and I enter. She must really want it I think to myself. I enter a...nd head for the bath room, brush my teeth and take off all my clothes. My cock is getting hard just thinking about what is about to happen. I walk into the open bedroom and see my sister lying in my bed. I go over to her and pull down the sheets she had covered herself with, she lets out a quiet moan. I gently slide beside her, and give her a hug.. She'd checked herself in the mirror. She didn't look odd or weird."I got made co-captain of the basketball team," Jody announced."Well, good for you," her dad said."Huh! Girls' basketball," Steve sniffed."What's that supposed to mean?" Jody glared."How could you even make a basketball team, short stuff?" Mark grinned."I'm not short, okay!" She was exactly five feet three, no matter how she tried to exaggerate it."You ain't no giant," Jason laughed."Midget basketball," Steve chortled."Fuck you. With a curt, unfelt 'Thank you, ' I dismiss the school ma'am and move to the rack of books behind my desk and find the tome I was reading the last time and heave the heavy, leather bound book back to my desk and settle down to read."Don't stare." I hear a voice whisper to my left and a young child's voice answer "But mummy, that lady is following the words with her finger and her lips are moving, you said only little girls do that when they read."I ignore the brat as it is dragged away,. I also thought it odd that I hadnt felt Billy come inside me so I wondered why he had stopped. I then felt his big strong hand gently teasing my clit and his cock rubbing between the cheeks of my bottom. His rubbing increased in speed and as I was coming down from such an intense orgasm, I was quickly right back up there and barely noticed the pressure pushing on my arse hole. Billys cock, still well lubricated from my pussy, push slowly but firmly against my rear entrance and before I was.
