The following is based on conversations my friend and I have had. She is the inspiration for this story's character, Marie Poland. Thank you for the inspiration!
My name is Nate Poland. I am 35 years old, single, available, no kids, a writer of erotica. I have always enjoyed what I do for a living even though it hardly pays the bills. No Nobel Prizes are given for writing smut! Haha!
I have a much younger sister, Marie. She is seven years younger than I. Just as I was graduating from high school she was starting to discover boys. Little did I know the only boy she wanted to discover was her own brother! I found this out one time when I was a senior in high school. I'd always been an active kid. Sports were my life. I lettered in baseball and football so I was very well-built. I am six feet tall, 190 pounds, jet black hair and eyes. I have a big chest, back and arms and well-developed muscles in my lower body. It also didn't hurt to have a nice package between my legs which got its own personal workout after I was done with weights.
It was nothing for me to work out in just my briefs, usually with the door open to allow air into my room. I also didn't have anything to hide so long as it didn't bother my family.
My bedroom window faced directly into the master bedroom of our neighbors, the Hendersons. Perry and Diane Henderson lived next to my family ever since we moved there in 1968. They had three daughters, Tracy, a year older than I, Roxanne, two years younger than I, and Beverly, four years younger than I. They were pretty girls. But, we'd known each other so long I never had any more than friendly interest in any of them.
Roxy and Bev took Marie under their wing when I left home since they were fairly close in age. They did typical girl stuff, gossiping about boys, trying on makeup, shopping and the like, and it was always fun to listen to them giggle as I came home from school every holiday.
One day, a couple of years after graduating from college and temporarily living at home again while my apartment complex was being renovated, I was going through my usual routine of curls, squats and bench press. I was standing with my back to the door, doing curls and wearing just my briefs when I noticed a glare in my bedroom window. I quickly rubbed my eyes to see if I could catch a glimpse. But, it disappeared before I could see what it was. I wasn't hard yet so whatever caught their attention couldn't have been much.
A minute later, I noticed the same figure glaring at me as I resumed my routine. Once again, I couldn't make out the figure. I put down the weights, turned around, and walked into Marie's bedroom. Marie was sitting Indian-style on her floor, going through her music CDs, her hair in pigtails, and wearing a little white halter and matching shorts, looking like your average 18-year-old.
I asked if she'd been playing a trick on me while I worked out. Without lifting her head to acknowledge me, she said she hadn't and I must have heard a noise. Without another word, I went back into my room, and was about to finish my routine, when I saw the mysterious figure a third and final time that day. This time, I focused on it long enough to see the white clothing it was wearing.
I immediately put two and two together and presumed it was, indeed, my little sister spying on me. Why she would do this with me I never could understand then.
I decided to pretend not to notice her the next time I exercised. I quickly undressed completely and jerked off before my routine so I'd be working out with an enormous hard-on. I quickly got huge and hard and put on my briefs again before starting my routine. I'd never worked out in this condition before. But, if it settled this game of sexual cat and mouse with my baby sister it was worth it.
15 minutes into my routine, I saw that familiar smallish figure staring at me through my window. Only this time I could make out the face as being that of my sister whose eyes were as wide as saucers seeing my big dick pointing out, bulging through my black briefs. She was licking her lips as she watched me. When she saw I was watching her this time she quickly vanished.
I purposely waited a couple of minutes, finishing my set of curls, before going into her room to try to talk to her. As I lay down my weights, I could hear the distinct low wail of crying. If that was her I felt awful for playing with her like this.
I walked into her room, and saw her laying face down on her bed, wearing a white tshirt and silk shorts, her legs splayed, her body bouncing up and down. She was, indeed, sobbing. All I could do was sit on the edge of the bed and stroke her neck slowly and tell her I love her. She apologized for spying on me, and told me she loved me, too.
She explained that the Henderson girls always thought I was hot. But, she poopooed their remarks until seeing me work out one day. She explained that she didn't have a lot of luck with guys at school, and figured I was as close as she would ever get to having a guy!
I told her I thought she was being too hard on herself. That she was cute, smart, fun, funny and loving, and any guy who didn't see that was missing out on a special girl. With that, she sat up on the bed, kissed me on the lips and told me she loved me. I told her I loved her also, but, this was as far as this would go with the two of us. Little did I know it was far from the end of this with Marie and I!
