How I learned about No Nut November part 4

I was soaked in sweat. My clothes were wet, my hair was wet, my — … You get the idea. Some sand from the carpet stuck to my back as I sat back up. Bruno entered the hallway and started licking my cheeks. I got up and looked around. I was standing in my hallway, drenched in my own sweat. Looking at the clock, I decided to take a shower. It was 3 am.
In my bathroom, I got out of my clothes and put them in the laundry basket before turning on the shower. Still half in my realm of dreams, I stepped in but shrieked and jumped out, nearly falling to the floor. The fucking boiler was, and is still today, an older model which needed some time to heat up. I waited for a few minutes and then stepped in the shower a second time. When done rinsing off the sweat, I stayed in the shower for a few more minutes, enjoying the warm water running down my body. Eventually I dried off and put on an oversized shirt, to sleep. Under normal circumstances, I'd sleep naked, but I feel weird being nude around the dog.
I couldn't sleep, though. I just laid in my bed for what felt like hours, not getting rest. Don't get me wrong, I was tired as hell. I just couldn't close my eyes for more than two minutes.
It was about 4 am when I gave up on sleeping and instead threw on a pair of sweats and a hoodie. Then I grabbed my jacket and keys and headed out the front door, taking Bruno with me.

The streets were wet and reflecting the lights of the few lampposts that lid it. Bruno was strolling through the bushes as I walked the pavement, watching the sky. Growing up in a city, I never really got to see the stars at night, and although I've been living here for a while now, I still look up to the sky at night feeling like a kid again. And so we walked for a while. Bruno disappeared from time to time, to hunt a rabbit, I assume, but always returned after a few minutes.
As I was walking towards the town, I came by more and more houses. Most of the windows had the shutters closed, some had the curtains closes and in a few was still light on.
One house in particular got my attention. The curtains were closed only halfway, as if someone didn't bother to close them completely. Through the gap, some moving lights escaped to the outside.
'Probably just watching a movie', I thought, but was still intrigued to get a closer look.
I was right. There was a movie running. A pornographic movie, to be exact. I got closer. There was a couch right behind the window. Then I spotted a very certain movement underneath a blanket and immediately turned away. Someone was lying there on the couch and jerking off.
'Figures', I thought, remembering the kind of film playing on the screen. I looked again. Whoever was having a wank there had removed the blanket, and I stared at his bare cock. Then I thought about how weird I was. Standing next to a random guy's window in the earliest of mornings watching him masturbate.
As I speed walked away, I noticed how this whole situation made me feel. Somehow aroused, yet disgusting. And only then, as the adrenalin shot through my veins, I noticed that I had thrown on a hoodie over my shirt and sweatpants and a jacket, but did not think of panties. It didn't make much of a difference now, as I was almost home by the time I realized.
