Incest Sex Story: Chapter 1 - Our parents worked late. My hot, seventeen-year-old sister, a real tease to my friends, was in my sex fantasies. I was fifteen, super horny and happened to sport a big, nine-inch cock. I jacked three to four times a day. (Oh, to be young.) Seeing her parade around the house in just her thong panties and midriff tee-shirt was more than a young teen could handle--even if she was my sister. I will detail how I found myself crossing the line, doing things no parent should know about.

I grew up not thinking much about my older sister. It was just us and our parents. It seemed like they worked all the time. Trying to get ahead and build the American Dream. So, once we became more self-sufficient, Leah would babysit me. After school our parents started to be away longer and longer. They usually came home from work at seven o’clock. That left us alone for hours after school.

I noticed Leah, but not in a sexual way until I hit puberty. Or puberty hit me! And man did it hit me. My body changed. I grew slender, muscular and sported a huge, nine-inch cock! I never knew how big it was, compared to other boys my age, until I was in the school shower and caught a couple of friends looking at it. It was flaccid, but still thick and hanging low. They said I had a monster between my legs and started laughing. Probably jealous. I didn’t really know what to say back to them. But I did notice most other guys had much smaller cocks.

A close friend asked me how big my cock was. Guys ask those sorts of things at that age. I had no answer. He told me I should measure it. Measure it hard. So, at home, I got hard—real hard—and set a ruler at the base of my shaft to the dripping tip of my cockhead. Nine and a fourth inches. I had nothing to compare it to. I hadn’t seen much porn then, and certainly not of dicks. That seemed gay, to me. And I was totally into girls, girls, girls.

That night on the phone I told my friend how big my cock was. He was amazed. Didn’t believe me. He said his was six inches. He told me he had to see for himself. I thought, sure, I don’t care. But I knew I wasn’t gay, and either was he, so no problem.

The next day, after school we were in my room. (And yes, Leah, was home, in her bedroom, in case you were wondering. I haven’t forgotten about her. This will all lead to her in time.) So, my friend Troy sat there waiting for me to pull out my cock. But fair is fair, so I told him he had to pull out his cock, too, so I could see. He hesitated but saw the reasoning. So, we both unfastened our belts, unbuttoned our pants, zippers down, pulled down our pants to our thighs, pulled our underwear down past our balls and watched our cocks start to grow. I played with mine to help it along, and then he did, too, with his.

His eyes were wide open in awe as he saw my snake unravel and stretch out more and more. It stood hard and steely, jutting up a bit--the big head drooling pre-cum, the shaft, thick and veiny. Troy swallowed hard.

“Man, you really are that big. Nine inches, huh?”

“Yeah, you want to measure it?”

“Uh, sure, if that is okay with you, you know.”

I smiled. I felt superior. He was my best friend, and we were cool with each other. And we shared a lot of personal feelings, and we talked about Leah a lot. He so wanted to fuck her. I wanted to, as well, but I didn’t tell him that. Too weird. Sick, I guess.

He put the ruler at the base of my cock shaft. I have to admit I was starting to get very aroused in a new way in my mind. This was something we had never done before. My cock was throbbing. And pre-cum was oozing down generously over my cockhead.
