Parents Out for the Night (Edited)

Our parents were out for the night and I was left in charge. It was a stormy night and the electricity had gone out, right in the middle of a popcorn and movie.
I had just come inside from smoking a joint and and checking to see that Tim & Caitlin were both OK and that neither of them had lit any candles. both were asleep.

I kicked back on the big sectional couch in the den listening to my battery powered Walkman when Caitlin came down the stairs, flashlight in one hand and pillow in the other asking if she could sleep on the couch till mom & dad got home. She was wearing a flannel nightgown right out of an episode of the Little House on the Prairie. High neck, long sleeves and came down almost to the floor

“Can I sit with you until mom & dad get home?”
“Sure Cait, go get your pillow & a cover”.

Caitlin and I were separated by just over a year chronologically but two years in school, so socially we didn’t know too many of each others friends very well. I knew that a few of my buddies desired to nail my sister and I certainly jerked off to the thought of fucking a few of her friends, especially Moira, a pert gymnastic teammate whose flaming red hair and luscious round butt captured my imagination.

Within minutes she lay down on her left side, her head was in my lap and tucked her knees up inside her pj’s. The warmth of her cheek on my crotch had my dick stirring in no time and I figured I better place a pillow between her head and my lap.

“There how’s that I asked?”

Within seconds her right hand slid below the pillow right onto my cock. There was no doubt about it, my little sister was copping a feel! Something in the back of my lusty brain said, no this is not good, but my dick responded quite differently to her tender touch and began to grow and harden. It only took a few second for my flaccid 5 inch dick to grow to a nice rock hard 7 inches.

I let my right hand begin running up and down her arm from shoulder to elbow, then elbow to wrist until my hand was directly over hers, and held it there in place ensuring that her hand was in full contact with my dick. I lightly ran my hand back up over her right arm, then down the length of her curled up body .
