When we were growing up my sister always felt she had the right to boss me around, even though she was only about one year older. Even though I'm now eighteen, she has somehow managed to retain that power over me.
Growing up together, we always shared the bathroom, and, even though you might think that would have changed by the time we were both almost twenty, she still felt she had the right to walk into the bathroom at any time, even if I was using it.
She was very annoyed with me when, on one occasion, I had locked the door while I was taking a piss. From the time onward if I was taking a shower, shaving or pissing, I always left the door unlocked.
The very next time, when I was shaving, she came into the room, pulled her jeans and panties down to her knees, and sat down for a piss. I glanced at her in the mirror, and felt excited by the idea that her pussy was exposed.
But when she had finished, she stood up, pulled her jeans back on, and, after running her hands under the bath tap, simply she left.
Another time, I was standing over the toilet, pissing noisily, when she pushed the door open and went over to the sink. She was wearing nothing more than an oversize t-shirt, which only just covered her ass cheeks. As I reached the end of my piss, I looked across the room at her. She was leaning forward over the basin, intent on the shape of her eyebrows. I couldn't help noticing that, as she bent forward, the shirt was pulled up, revealing not just the curve of her ass cheeks, but a hint of lips of her pussy between her legs. It made me feel so horny, knowing that I was looking at her naked pussy, even though couldn't see it clearly enough to make out any details.
And there I was, standing looking at her like that, my cock in my hand, and as far as I could tell, nothing at all was happening as far as she was concerned.
I really couldn't make us my mind whether she was just teasing me or if she wanted me to make a move, to touch her. It was even possible that she was oblivious to the effect she was having on me altogether.
When I was with her it never occurred to me to do anything, but when I lay in bed at night, replayng those moments in my head, I felt stupid for having done nothing and I would resolve to act.
A few days later I was standing at the washbasin shaving, when she came alongside me; even gave me a nudge to move over so she could use the sink at the same time. She was wearing a t shirt, as she often did at night, with no bra; I could see her nipples pressing against the fabric. Without hardly a thought, unable to resist the temptation, I reached out my fingers to touch her.
Immediately, she brought her forearm up protectively in front of her, and with an offended frown, asked me indignantly what I thought I was doing.
So I never knew quite what the situation was; I put up with it because I lived to catch the glimpses of her body that I was allowed, and there were also days when she would make something extraordinary happen.
There was one evening when I was in my room, writing code on my computer. Of course being at a computer, even if you find programming as exciting as I do, and I honestly do, there are still times when you find yourself distracted by porn of one sort or another. And so I ended up lying on your bed, with one hand on my dick, and the other hand searching for something truly inspiring.
It was then that I heard the smallest of knocks on the bedroom door and, without any waiting for a response, the door opened and my sister's face appeared.
She stood there for a moment, surveying the scene, before asking, "What are you doing?"
Feeling ridiculous and embarrassed, I was trying to pull up my boxers to cover my now limp penis at the same time.
