I go to a college down south and from when I got my own room when I was a teenager, I always felt more comfortable sleeping naked. In school, I live on the ground level in a single room, so I usually keep the blinds close. However, the day this incident happened, I had kept the blinds and window open because it was one of those nice breezy days. That night, I went to a small party among friends and later came back to my room, took my clothes off as I always do, and covered myself in my sheets. I had completely forgotten that my blinds were still open.
I woke up later that night (can't remember what time but it was still dark in my room) with an erection and feeling horny. Naturally, I began to rub my penis under the sheets until the sheets became annoying, so I uncovered my naked body. At this point I should say that when I sleep, my head is facing the opposite direction of my window...that is to say that the window is directly behind me. Anyways, I kept stroking myself until I began to feel the first signs of an orgasm. Then for some reason, I suddenly remembered the window was open and I quickly turned around.
Well, a pretty hot, young, petite brunette I didn't know was just staring at me through the window. As soon as I saw her under the lights of the sidewalk, she quickly began walking away as if she was embarrassed for watching. But if she thought she was embarrassed, she didn't know what I was going through. My heart was pounding, I was completely shaking, and my penis became flacid real fast; it was the first time I was caught jacking off. I tried not thinking about it and going to sleep, but I couldn't keep from recreating the scene over and over. Eventually in the early morning hours, sleep finally took over. I do admit that the next night, I did cum to the thought of her masturbating to what she saw. Unfortunately, I still don't know who she was.
