I hadn't planned it, hell most of the time I can barely stand to be around her, but this time, this one time something happened and well, for a brief moment I saw her completely differently than I ever had before. Throughout high school she was my kid sister, actually more popular than me, she got to be a real pain in the ass. I was so glad to finally graduate and go off to college and get away from her for a while.
Of course I really didn't count on her following me to the same college a few years later, but at least there she was in her dorm and I was off campus in an apartment. She seemed to have grown up a bit and now when we ran across each other on campus it was as least cordial. I actually looked forward to the holidays and the long break we'd have. I thought it might actually be nice being near a real, civil human being for a change.
Thanksgiving went fine, but with all the Christmas shopping and all, we didn't see a lot of each other, but the few times we were around each other, like at Thanksgiving Dinner and then on the weekend watching football, we got along very well. Just like any normal brother and sister which was an abnormal thing for us. Perhaps she was growing up a bit.
Anyway, Thanksgiving ended and I got buried in finals. She must have been too because I didn't see her until I pulled into the driveway at our house for the start of Christmas break. She had finished a day earlier than me and came home right after her last test. I finished mine and hung around until my grades were posted.
I was in a good mood because I had received three A's and two B's, not quite the dean's list, but close enough. Sis' grades weren't as good, but what can you expect from a freshman. She did get one A, two B's and two C's, not earth shattering but reasonable for as much playing around as she must have done at the dorm.
We both had most of our shopping done by then so there wasn't much for us to do but hang around the house. Things went well as we helped our parents decorate the house and get ready for the week of Christmas when we expected our grandparents to stay with us for a few days. Even mom's obsessive cleaning wasn't too bad with sis and me helping out.
It wasn't until later in the week when dad was at work and mom had gone out shopping, leaving sis and I at home alone that I wondered if the old, evil sis had suddenly come back. Everything was fine until I went into my room and I found my laptop was gone and my desk basically ransacked. "Oh fuck, the bitch is back," I moaned to myself.
I headed straight to her room and barged in without knocking or anything, shouting, "Where the hell is my laptop and why did you ransack..." I stopped mid sentence because I saw her on the bed wearing only panties. The computer was propped up on a pillow beside her and she was rubbing her nipples with her hands.
She looked up at me and said, "Damn, I thought I locked that. Anyway I needed to borrow your laptop, I knew you had some good porn and well, I just needed to, well... this. Of course you had a password so I had to mess up your desk searching for it."
I hadn't moved and really didn't hear anything she said, my eyes were now focused on her, more specifically her panties which had an enormous, darkened wet spot. Before I could move or do anything else she said, "At least lock the door."
Without moving my gaze, I reached over, pushed the button on the door and shoved it closed. I then took a step closer to the bed, oblivious to everything but the wet spot. My cock was getting hard and most likely poking out in my pants but I didn't move.
