The Janitor Used Me

So it happend when I was 13. Back in the days I was doing a lot of sport and stuff. I was pretty good at sprinting so my sports teacher allowed me to use the gym on my own after the afternoon sports class was over. I did that for a few weeks and usually the janitor would come around 5pm and tell me to wrap up for today. The Janitor always looked a bit creepy to me, he was like around 1.90m and had a lot of muscles. So one day I was practicing at the gym and it was around 4:30pm. I was feeling tired that day so I taught ill leave earlier, but first I needed to go to the bathroom. There were 5 urinals and I picked on towards the midle. So while I was lowering my pants I noticed to bathroom door opening. It was the janitor, he looked at me with a neutral face, said hi and took the urinal to my right. Since I was a kid I can't really take a piss if someone stands besides me, so thats the reason I only use urinals when I'm alone. So I was standing at the urinal with my dick in my hand and trying my hardest to pee. On my right side the janior was peeing and talking to me. It was really uncomfortable talking with someone while trying to pee. I really didnt listen to what he was saying but after a while I realized that his face has gotten angrier and that he was done peeing a long time. So I said that I did not listen and asked what he said. He looked into my face and said something like "you are the reason why I'm getting off late of work blablabla". I was kinda scared and apologized, still unable to pee. He said that he does not give a fuck about my apology and that I needed some punishment. I said that I was sorry once again and that I wanted to leave. He pulled up his pants went to the door, pulled out his huge keyring and locked the bathroom door. I was shocked and turned my body to the door, still with my pants down. He was moving towards me in an aggressive manner which scared me very much. I said that I dont want to get hurt, he laughed. He came up to me and told me to take off my shoes, pants and undies and then he grabbed me by my armpits with his huge hands. Just like that he was lifting me into the air, I was squirming but there was no chance to escape. While holding my thin little 13 year old body into the air he walked towards the wall pinning me against it. I was still squirming and telling him to stop but he didn't. So I was pinned against the wall, basicly nude and had no chance to escape at all. He was very close to my body and he agressively told me that I should rest my thighs on his shoulder and be quiet. He added if I was thinking about telling anybody he would beat me until I couldn't run anymore. So I was there, my hands pinned against the wall, my legs resting over his shoulders and then it begun. He took my cock and my balls in his mouth. He was swirling around with his tongue like crazy eventually getting me hard. I hadn't thought about sexuality much around this time, but I realized I was getting r**ed. I was so scared. After what felt and eternity my dick begun to feel different. I was shaking and my dick felt incredibly warm. By that time his mouth relentlessly sucking my cock gave me huge pleasure. So I instinctively started lightly pounding back at his lipps. His movements got faster and "deeper" and a short time later my body violently startet shaking. The amount of pleasure inside my dick was something I hadn't felt before. He literally burried his face in my crotch, pressing as hard as he could against me while I pumped my first squirts of semen down his throat. After that he let go of me and told me that every thursday afternoon I needed to come in the gym bathroom, otherwise he will get me kicked out of school. So for the follwing three years I did what the janitor said, visited the bathroom every thursday afternoon and was forced to empty my balls in his mouth every time.
