It had been exactly a month that you had been back in the house. To be honest at first I was not thrilled. When you moved away to college dad converted your bed room into his study and for about two years your bed stayed in a shed outside. When you asked to move back in after flunking out of school there were only so many places left to put you, one of those places was my room, which is where you ended up.
Tensions were high those first few weeks. Our parents had spent good money sending you off to art school and often I could hear the three of you arguing from what was now our room. We didn't talk much either during those times. If we happened to be in the room at the same time, you were quick to put on your headphones to lie down and pretend you were sleeping. Not that I had much to say to you. At the time I was pretty pissed off about your failure, after all you were encroaching upon my personal space.
At first I tried to ignore it. After all I knew what you were doing, I wasn't a little girl anymore and acknowledging it wasn't going to make the situation any better. It wasn't really bothering me either so why not allow you to have this time for yourself. You had been used to life in your dorm when you could have probably jacked off whenever you wanted, so I had sympathy for you since now you had to wait for me to go to bed. Of course curiosity ultimately got the best of me. It was easy that first time. I had already been facing your direction, your bed, placed directly across from mine was in plain view. The laptop that you had precariously balanced on your lap gave off just enough light for me to catch it all.
The old t-shirt t you slept in was pulled up resting across your chest, and your comforter was thrown to the side. At first all I could see was the thin sheet that covered you moved with your motions, but after a while I can only guess that was too much for you. There was no point in staying covered; after all you thought I had been asleep now for hours. You threw the sheet off and that was the first time I had ever seen yours. To be honest I was shocked. It wasn't that I spent a large amount of time wondering what my step brothers' cock looked like, but if I had ever put any thought into it what I had imagined and what you were stroking were two different things. I think that was one of the reasons I watched you that first night.
It had been weeks since that night and I purposefully stayed awake each night to watch you. I knew your habits like clockwork by then. First you would say your goodnights to me and crawl into bed, facing away from me. You'd lay there for an hour or so maybe even actually falling asleep, and then you would wake up, check the time on your cell phone and then pick up your laptop. You'd play around on Facebook for a while or some other social media site but you'd eventually get bored with that and go to more risqué sites. You'd watch and it wouldn't be long until that bratwurst in your pants would start to rise and push your laptop up. Finally you'd slide your computer down to just above your knees and pull it out. Even at half mass it was a sight to behold. It was thick with a distinct head. I wasn't a connoisseur of cocks but yours was rather beautiful. You'd start of slow, and quiet but eventually you would pick up the pace and that's when the sounds would start. I loved listening to you. Loved the stifled moans you tried in vain to choke down. Loved the way your back would arch or the way you'd move your legs .I loved the way you would eventually throw your head back, ignoring the images on the screen in front of you and I especially loved that final primal grunt as you spilled your seed all over your stomach.
I'd be lying if I said it didn't make me a little excited down below watching you. Although we had grown up together, our parents marring when we were both relatively young, I had noticed how attractive you'd grown. You had beautiful glistening green eyes and a strong gnaw line that looked great with or without facial hair. Since you had been off at school you had allowed you hair to grow longer and now I could say without a doubt that you had the most luscious head of long brown waves I had ever seen. Your body was nice looking too, you had lost a lot of weight when you moved out and it was replaced with muscles. You didn't look like a body builder and with your clothes on no one would really notice but with your shirt off, watching your chest heave up and down as you stared at the ceiling; well...I could tell you had been working out.
I'd normally go to sleep after that, taking care of myself in the morning if I was still aroused by the thought, and often I was. And for a while things went on just like that.
That is until you looked back.
It was a night like any other, I'm sure you remember it. You were in bed. One leg bent at the knee while the other hung over the edge of your bed and you were going at it. Something must have gotten you worked up because you barely paid attention to the pornography you were watching. Your eyes were closed and your head was back and I was enjoying the show. That is until you turned your head and we locked eyes.
I didn't know what to do, which is why I didn't do anything. We gazed at each other from across the room and you never missed a beat. I silently hoped that perhaps it ws too dark for you to be able to tell that I was awake, but there was something about it that assured me that those hopes were all in vain. It seems like it went on forever like that, with us looking at each other but it couldn't possibly have been more than a minute or two before you came. You broke contact with me then, grabbing the towel you kept on your bed, cleaning yourself off and then just as normal you turned around and went to sleep.
It took me a while to go to sleep after that. Something about you seeing me, looking directly at me, shook me. Maybe it was because it made the fact that we were sharing this room very awkward. Or maybe it was because I thought you would have been bothered by it, seeing your step sister watch you jack off like that. I was sure you'd say something to me about it the next morning, that you'd chastise me or perhaps try to smooth the incident over.
But the next day went on like it didn't happen. By the time I woke up you were already down stairs. I avoided it as long as I could, talking to you that day but by the time dinner came around mom sent me to retrieve you from our room and it couldn't be avoided any longer.
"Trent?" I called nervously as I knocked on the bedroom door. I had never knocked before; after all it was my room. You were just a guess here until you got enough money to move out.
"Yeah?" you responded.
"Mom says dinner is ready!"
I waited but didn't hear anything.
"Trent?"
"Open the door I can't hear what you're saying."
I opened the door without another thought, after all what could you have possibly been doing this time of the day? I paused as soon as I stepped into the room. You were sitting on your bed with nothing but a pink towel folded loosely around your waist. There were droplets of water sparkling like glitter on your toned body. I know it must have been obvious that I was caught a little off because you chuckled.
"I hope you don't mind me using one of your towels, all of mine are in the wash."
"No, it's okay." I was having a hard time forming words. God you were really attractive.
"So what were you trying to yell through the door?"
"Mom says dinner is ready."
"Well it's about time." Without saying anything else, without asking me to leave or close my eyes, you stood up, the towel falling to the ground and walked over to the clothes basket you kept your clean clothes in. At first I was shocked, that's defiantly what kept me in the room. We had been raised rather conservatively; the decision to even now let you sleep in my room had caused an argument when it was first proposed. So needless to say I had never seen you completely naked. I watched you, mouth hanging slightly open as you pulled out a black band T and pulled it over your head. You then turned your attention back to me.
"What?" you asked rather playfully. "I know at your age you've seen a naked guy before."
"Well yeah." I paused for a moment as I reviewed your last statement. "What is that supposed to mean?"
"Nothing, god, don't be so sensitive." You pulled out a pair of gray boxers and quickly pulled them up then returned to rummage through the basket again. "I had seen a naked girl by the time I was your age so I was just assuming."
You pulled out a pair of ripped skinny jeans and pulled them on with ease. As you walked towards me your bear feet still left wet prints on the wood floor.
"It's just the human body, nothing to get weird about."
With that you walked passed me and headed down stairs. I thought that was your way of telling me that it wasn't that big of a deal, you catching me watching you. But I had completely misread the message behind your words.
Dinner went well. Your father hounded you about getting a haircut and my mother got him off your back. She thought it was more important to ask you about when it was you were planning on getting a job. All and all it could have been any other night. Except for the way you kept looking up at me. I wasn't particularly active in the evenings chats, The one plus side of your return was that that it gave our parents something to talk about other than me, but even with my silence you kept glancing up at me. It wasn't anything threatening or uncomfortable in fact it was almost seductive. At first I tried to ignore it but after a while it became something like a staring contest. You'd look at me, always smiling, until one of us would look away.
