"How my Little Sister Stole my Girl fiend"

short story by Rockhead

Growing up my little sister Amy was always a brat. Smart and mischievous, she seemed to delight in nothing more than making my life as difficult as possible. Mom had kept her dressed in the cutest clothes, pigtails, and bows. She was always the center of attention. Despite all the super sweet girly girl stuff, she was very active and a bit of a tomboy. Oh, and I guess nature must have put a little too much testosterone or something into the mix because she has a dick!

Amy was a perfectly normal little girl in every other physical aspect. I know this, of course, being that I am two years older almost to the day I used to help my Mom give baths and had innocently inquired about the difference between myself and her. She had explained to me the difference between boys and girls, and why my sister was special. I also grew up with an understanding of why her difference had to be kept secret.

I honestly never paid it much mind and we went through childhood together as normally as any siblings do. I went through puberty and the corresponding changes that go along with it.

I began to date girls from school and often times they would come over and hang out at my house. As girls often mature earlier than boys, Amy wasn't too far behind me when she began to blossom.

It was about this time frame that I began to notice a strange pattern of behavior from her.

She seemed to have no particular interest in boys either at school or the typical teenage heart-throbs that pubescent girls always woo over. She did however pay quite a bit of attention to the girls that I brought home. She seemed to go out of her way to be around when I would have a girlfriend over and I can't think of a single one that hadn't developed some sort of friendship with her. Occasionally, as my girlfriend at the time sat watching TV, we would begin making out and heavy petting. After a while Amy would always get up and leave abruptly. I wasn't sure why. I naively assumed she was being polite and allowing us some privacy. It took a bit of a shocker to wake me from that disillusion.

One afternoon, shortly after my 16th birthday, we were all sitting in the downstairs living room watching a movie. My girlfriend Sarah, a very pretty and stacked blond from school, were going at it kinda heavy on the couch. I couldn't help notice that Amy was paying alot more attention to what I was doing than to the film. I also noticed that she had the blanket she always snuggled with bunched up over her lap. 'I don't believe it' It finally dawned on me. 'She's getting excited by watching us'. I decided on a little experiment and proceeded to begin groping my unaware girlfriends big tits through her too tight little tank top making hard nipples strain against the thin fabric.

Apparently our little display was too much for Amy as she almost immediately stood and walked up the stairs without a word, still clutching the blanket loosely in front of her.

I waited a few moments after hearing one of the upstairs doors shut and then excused myself to use the bathroom. I silently slipped up the stairs and down the hallway to the bathroom door. It was closed, as I had expected but an almost inaudible, high pitched mewing sound issued periodically from inside. 'I was right!' I thought 'she's in there fingering herself, or jacking off... or both!'. I'm not sure what came over me at that moment but for some reason just knowing that she was doing it wasn't enough. I hadn't thought about her "Differences" for so long this just raised a thousand questions in my mind. I had to see for myself.

The house we lived in was quite old and actually had old fashioned key holes in the solid wooden doors. My family had never been concerned with them though as the rules of common decency had always been strictly enforced. 'To hell with decency' I thought as overwhelming curiosity got the better of me. After a quick glance around, I leaned down to the keyhole and peered through. I wasn't nearly prepared for what I then saw.

I had been right. On that point there was no doubt. She was indeed both fingering herself with one delicate little hand dipped between her legs as well as jacking off her girldick with the other. This was not what shocked me.

Now I've always felt I was an average sized guy maybe a little more than average. About

six and a half inches long, maybe even seven right as I cum. I hadn't actually seen Amy's dick in many, many years and hadn't even considered the possibility that it had developed along with the rest of her body. B
