It's very late now. I spent a lot of time running that day, so I decided to stay up late tonight to review.

The room upstairs is very small, almost cramped. It's empty and dark. There's only one window facing the street, and several single beds (my bed is by the window, and my roommate's bed is by the door). There's a desk by the window, a ceiling lamp, a table lamp, a small potted plant, and a cup filled with pens and pencils. I like to study at this desk. This way, I can better feel the cool breeze that blows in through the closed blinds because we usually keep the screen door open.

My roommate wasn't at home, leaving me alone in the room. My strong body was sore from the efforts I made earlier in the day. I've been trying my best to keep fit and pursue the running talent that my family takes for granted. We always compete with each other, but it seems that I always come last. Well, it doesn't matter. Right now, I'm in a learning state. However, the gentle breeze seeped in through the gaps of the closed blinds, along with the soft and rhythmic sounds from the street below, causing my thoughts to wander...

When I felt that familiar tightness in my groin, I was a bit taken aback - my penis began to get engorged. I'm young and my physical condition is good due to frequent running, so this kind of situation is not uncommon. I usually take a bath at least once a day - sometimes more - during two or three showers. The city where I go to school might be very hot, and because I love sports, I have to pay extra attention to taking frequent baths, otherwise not only would I look like I was running outdoors, but I would also give off a distinct running smell. But when I felt physical pain, not just because of running, did I remember that I had rushed to take a bath in a hurry because I was in a rush to study. But now, my studies are very difficult, and there are more than one difficult aspect.

Well, I thought, I have to deal with this matter; otherwise, nothing can be accomplished. - At that moment, I had already read the sentence in my textbook four or five times. I stretched my body and stood up. The gentle, velvet-like air drifted in through the window, feeling very pleasant. I stood sideways, and the bright study lights outside shone like spotlights on me. As a devout Christian, I had always been cautious and refrained from doing anything out of line. I was a virgin, always hoping and praying that one day a beautiful woman would come into my world. But now, she wasn't here, and my thin cotton shorts became harder and bulged as my penis grew harder. In my heart, this was the place to handle things. It would be best to deal with it before my roommate came home. Our small room was not very spacious, so I stood sideways there, with the window on my right, the blinds closed, and only the slats of the blinds were gently swaying in the breeze. I assured myself that no one would be able to see me like this.

I slowly moved my hands towards my lips and gently caressed them. My penis became harder and harder. I let my hands move to my chest, roughly squeezing the pectoral muscles, and then gently teased the erect nipples through the T-shirt. To make it easier to enter, I quickly took off the T-shirt. My body began to get a little moist. As I pulled down the waistband of my pants, I slowly and seductively pulled down the shorts... down... down... The anticipation grew stronger and stronger.

My erect penis popped out, arching upwards, with a series of sharp pains. My shorts wrinkled and fell to the ground. My right hand gently caressed the glans, grasped it, and then moved downwards. My left hand continued to fondle my nipples, alternating left and right. I slowed down and admired my erect penis under the bright light of the small room. It was taut and full, throbbing with vitality, and the tip was slightly moist. I had measured it before and knew that its quality was above average. I longed for the day when I could show it to others.

When these thoughts and fantasies emerged in my mind, my body began to twitch slightly, my breathing paused several times, uncontrollable gasps and sobs escaped from my lips, and my fingers automatically controlled themselves...

The pressure kept increasing until my ears almost buzzed from the intense pleasure. My penis trembled, and my entire body convulsed violently. A stream of white liquid gushed out, followed by another, another, another...

I stood there, my legs trembling, with a wild passion, greedily licking the semen that had stained my trembling hands.

Suddenly, two car horns sounded outside the window. Then the car slowly drove away and the sound woke me out of my trance.

Wait a moment... What? Has anyone parked the car outside?

I quickly pulled up my shorts and put on my bathrobe. The semi-erect penis was still secreting semen. I walked into the darkness and hurriedly made my way down to the street below. There was no one there. I looked up at the window and, in horror, discovered that all the things in the room near the window were illuminated by bright lights, with clear outlines visible. Just a few minutes ago, I was using this bright light to study. The outline of my desk was clearly visible, and there was a familiar cup with a pen and pencil in it, as well as a small plant I had placed nearby. But this meant...

When I realized that these were not the only "objects" that had been so clearly presented just moments before, my heart skipped a beat - during those moments, I was certain that someone had, with a profound meaning, pressed the horn twice before slowly driving into the darkness.

I returned to the upstairs, my mind filled with countless thoughts. Were the honking sounds and the engine noises just figments of my imagination? I still felt that the intense climax just now left me dizzy. Sometimes, changes in one's mental state can make people hear things that don't exist at all. Besides, the streets can be very lively at night, so perhaps the honking sounds weren't even directed at me...

But even this final idea sent a chill down my spine, because I realized that, whether on the street or through the windows of the low buildings across the way, many people might have witnessed my passionate struggle. On the other hand, there was also a possibility that some people might even be too lazy to glance up at the bright window and the clearly visible figure outside it.

For some reason, I don't know if anyone witnessed my unintentional revealing behavior, but this instead intensified the growing excitement and thrill that was building up inside me. Usually, I am very cautious and would feel ashamed of any deliberate exposure of myself. But I knew I was doing the right thing, and this somehow prevented me from experiencing the intense guilt that usually comes with intentional actions.

I admit that when I was standing outside the building, my thoughts began to drift to some dark and obscene places. If that car really stopped right outside my window on purpose, then what exactly happened inside the car while they were watching? Without much effort, one can imagine that these thoughts would only make my heart race again, enjoying that peculiar and lascivious sense of satisfaction: perhaps I could bring some kind of sexual pleasure to a complete stranger - and even possibly share this pleasure during the moment of sexual intimacy.

I stood in the relatively quiet night, surrounded only by the hustle and bustle of the city and my excited and rapid breathing. It wasn't until a speeding car passed by that it woke me up from my sensual daydream.

"All right, no matter who you are... I hope you enjoyed this performance!" I walked towards the door, whispering softly in the darkness.
