Both these people are over eighteen.
My brother, Billy, is a couple years older than me. I came to live with him in the city when I started college, and, since then, we've had a fairly standard roommate-type relationship. At least, that's what I thought...
It all happened when I was on his computer. I wanted to put a bunch of songs from his iTunes on my Kindle, and I've often just gone on his computer for things when he's at work or whatever. I was looking for the folder he keeps that stuff in, when I stumbled on one labelled "Jenny"(my name, in case you hadn't guessed). Curious, I opened it, thinking maybe he had pictures of me from various family events.
What I found was about two dozen TXT files, all labelled "Jenny 1" and so on. I clicked on the first one, and it was some kind of short story:
I've just woken up, and I'm walking through the apartment with a cup of coffee, when I find my little sister, Jenny, out on our apartment's balcony, reading a book, wearing this cute little two-piece number, her red hair tied up in a pony tail. I find myself staring at her large, squishy boobies, then moving down to her soft, pudgy belly, then down to her area, and I moan a little. Suddenly, I feel my cock quickly harden, and almost stick out of my boxers. Finally, I just put my cup of coffee down, and go outside.
"Morning, Billy." I don't verbally respond. Instead, I instantly kneel down in front of her. "Uh, Billy?" I then spread her legs, push the crotch of her bathing suit aside, and start licking Jenny's pussy. "Billy..." My little sister starts breathing hard, and moaning, as my tongue probes deeper and deeper into her quickly moistening snatch. Speaking of that, her juices taste really good, so much so, I might just make a thing of eating her out every day. Judging by the sounds she's making, I don't think she'd object. Finally, I start licking and sucking on her throbbing clit and, I can tell by her voice that she's about to cum. When she does, she lets a high-pitched whine, which I'm half afraid might alert people on the street below. I stand up, and Jenny is smiling gratefully at me. I go inside, and get ready for work.
Needless to say, I was a bit confused and upset after reading that. How long had my brother been thinking these things about me? I felt like I wanted to cry or scream. I probably should've just gotten out of there, and drank until I couldn't remember what I'd read, but something compelled me to look at the next one:
Me and my sister, Jenny, are watching TV one night, and quite frankly bored by the lack of anything on. Suddenly, Jenny crawls over to me on the couch. "What are you doing Jenny?" My sister answers by kissing me on the lips. We start making out, and groping at each other. In the midst of this, my sister moves her hand down, and starts rubbing my already hard cock through my pants. Suddenly, she gets down in front of me, and starts undoing my belt. After she gets that open, she unzips my fly with her teeth, and pulls my pants down a little. She then reaches into my boxers, and pulls out my throbbing cock. Smiling up at me, she strokes it, then leans down, and wraps those luscious lips of hers around the shaft. It feels incredible, as she licks and sucks on my swollen head, and strokes the shaft. My sister slowly coaxes me toward orgasm, until I can't hold it in anymore. My cock contracts like it's gonna get a charlie horse, then it lets go. I can hear my little sister rapidly swallowing, getting every drop of my jism as it comes. After teasing my now sensitive cock with her tongue a bit more, she smiles up at me, and I smile back.
