I didn't grow up with any weird and nasty thoughts about my sister, Allie. I always cared about her and took pride looking out for my little sister. But I can't point to any single event or anything weird or out of place that would lead me down the path we would eventually go. However, the summer that I was set to go off to college would change the course of my entire life and I'd like to think that of Allie's too. I left for a summer job at a National Park several states away, returning home the week before Allie was to start her senior year of high school. I still had an extra week off before I needed to be two hours away at my college. I planned on seeing all my old high school buddies and drinking most of the week away.
Allie was only a year younger than me, 13 months to be exact. We both had the same green eyes and black hair, though I always kept mine short and hers was always very long, even by most girls' standards. I'd never noticed Allie's breasts before that summer, but I'd guess they were solidly in the B cup range. She was athletic, but so was I. While I was probably the more outgoing of the two of us; Allie loved to read, not that I'd call her shy, just maybe quieter than me.
I remember getting home in the middle of the afternoon. I had told Mom and Dad to expect me home by dinner, but being a teenaged boy, I'm sure I drove a healthy bit above the speed limit and was at least two hours early. When I pulled into our driveway, I didn't see Mom or Dad's car, not that I was expecting them home at that time of the day. So, I headed inside knowing the only one who even might be home was my little sister. I called out a couple times as I entered, setting all my bags down. Instinctively heading into the kitchen and checking what was in the fridge. I called out a couple more times, specifically for Allie, but didn't get a reply, only our cat and dog seemed to notice me.
I finally concluded that I was home alone and even flipped on the tv for a moment, as I hadn't had access to one in months. Eventually I saw my bags lying in the entryway and I got up, grabbed them, and headed down the long hallways towards my old room. I passed Allie's room, glanced in it, but it was empty and more or less exactly as I had remembered it. Mom and Dad's room was also empty. I made it to my old room and threw my things down. It felt good to be home.
I don't even remember why exactly I got up and went towards the bathroom that I had always shared with Allie. I assume it was to use the restroom, but to this day, I can't say for sure. I remember the door was closed, but I didn't hear anything inside. The image I saw when I opened the door will be forever burned into my memory.
It was Allie.
She was standing sideways initially, looking at herself in the mirror, and she was completely naked. My eyes immediately slid up and down her firm, athletic figure. Her profile could not have been more stunning; her breasts were perky and perfectly proportioned to her body. Her toned thighs curved at just the right moment to cover the apex between her thighs. And her ass... it seemed muscled and soft all at the same time. Her hands were stretched upwards as I finally realized that she was, in fact, wearing something... she was running a towel through her hair.
I don't remember saying a single word, maybe I did, maybe it was the door opening unexpectedly, but for whatever reason, Allie turned to face me.
If I thought the profile of her body was perfect, her facing me was something from an entirely different planet; an even better planet.
Allie's breasts seemed to stare a hole right through my soul. They fit her perfectly, more than any pair of breasts have ever fit any woman before. Her soft pink areolas gave way to two slightly dark red nipples which both seemed to be perfectly hard. I remember a small freckle on her right breast. I remember it from that day and over the next couple of years I would actually use this to aim at as I exploded on her chest. This freckle is above her nipple and slightly off center, closer to her other breast. If you look really carefully, depending on the shirt she's wearing, you can even see it sometimes when she's dressed. As she turned to face me, the slightest little bounce between them both is still the hottest thing I have ever laid eyes on in my life.
My eyes then did what came naturally and followed further down her body. She had a small patch of black hair down there. The same color as the top of her head and the same color as mine. Now I had always trimmed and kept things neat and tidy down there and apparently my little sister was the exact same way. The hair was trimmed closely enough that I could just barely make out the outline of her soft pink lips.
I stared at Allie. I had never seen her like this ever before. In that moment she wasn't my little sister but a woman. A woman that every instinct in my body wanted. A woman that I wanted more than any person in my life before or ever since that day.
I don't remember either of us saying a word. I do remember looking up into her face as her green eyes shot back into mine. Her face was beautiful, she didn't seem shocked or angry or even happy for that matter. There was a quiet, confident look across her face. It's a look I've actually searched for over the years since, but I've never managed to see again. I've even searched for this look on other's faces, but I don't think it exists outside of Allie's on that one August afternoon. And after a minute, or even five minutes, I don't know, something caused my brain to turn back on and I gently took a step back and quietly went back into my room.
My mind raced, the image seared into my brain. "Why am I having these thoughts? That's Allie, my own little sister! Stop it! Fuck, why am I hard?" I screamed at myself inside my head. I stayed in my room for the rest of the afternoon. I heard her eventually leave the bathroom, I put my things away, but I didn't show my face until I heard Mom come home after work.
I went down and saw Mom, talking to her nonstop until Dad arrived home a few minutes later. I had never been so glad to talk to my mom; to talk to anyone, about anything, anything to get my mind off Allie. I helped Mom make dinner the same way I'd done a thousand times before. I set the table, filled glasses and was good, until Allie came down and scampered across the room to the front door. Her hair was pulled back in a high ponytail, she was wearing a soft cream sweater that hugged her body perfectly, with leggings and the type of socks she always referred to as her "cozy socks."
She answered the door to her best friend Lisa, who was an honorary daughter to my mom and Dad. It seemed like she ate dinner at our house more than her own, so her presence didn't come as a surprise.
We all sat down and ate. Mom and Dad controlling much of the conversation as they were both happy to have all their kids back at the same table. They questioned me about every detail of my summer job and upcoming college plans. Allie didn't say much but I could tell she was listening to everything. She seemed happy to have me back home even if it was just for two weeks. I tried not to look at her, at least not too much, but I failed in that.
At Lisa's prompting, Allie mentioned that the two of them were going to try out for the Fall play at school, a murder-mystery thing or something. While I tended to gravitate towards sports, Allie had actually found her calling in theater and drama. I took this as an opportunity to continue one of my long running jokes with Lisa.
