Masturbated a little too loudly while listening to my roommate, and now I'm forever embarrassed

This past Friday, I was hanging out in my room playing video games online with my friends. We just finished our valorant session and I went out to get some water and take a breather after losing all night. My roommate has been seeing this new guy for a bit and they were hanging out in the living room. I opened my door loudly to try and give them a bit of a warning that I would be walking through, and it was just as well as I noticed my roommate quickly sitting up and them adjusting the blanket a bit on the couch. I snuck by as quickly as I could and went back into my room to watch some tv.

Maybe an hour later, I heard some giggling and my roommate's door close across the hall. Our rooms share a wall, and it's not the first time she has brought someone over for a quick session, so I knew what was coming. I turned up the volume a bit and tried my best to ignore what was going on next door. But over the next few minutes, it was getting a little impossible, as I started to hear the distinctive sounds of my roommate's moans. I know it's a little weird of me to listen, but I've been a little sexually pent up for a bit. Before I knew it, I had turned muted the tv and my hand was sliding down the front of my pajama shorts. It's been a dry spell for me in that department for a while, and for me, using my imagination like with sexting or listening to others has always been the biggest turn-on for me. I closed my eyes and started rubbing myself, and I felt myself get so wet so quickly. I found just the right spot and was egged on by the rhythmic moans of my roommate next door.

Even though this wasn't the first time I've done this, it felt better than normal, and I involuntarily let out a few moans and gasps as I felt mini waves of ecstasy coming over me. As I kept going, I heard my roommate moaning louder and louder, and then her saying "yes, yes, baby" as she was unmistakably getting closer and closer. I was completely lost in the moment and her cries were so hot that I brought myself to my own orgasm. I kept my eyes closed and kept rubbing myself. A few seconds later I arched my back and came hard. It felt so good that I forgot I needed to be quiet, and cried out, "oh fuck", as I did.

Then the post-orgasm clarity came rushing in, and I realized "oh shit, did I just do that". I froze with my hand still down my pants - it was complete silence from the next room too. Then, in what felt like an eternity of stillness, I heard laughing next door. I don't know if they heard me or if they were lost in their own moment too and were just having a moment together, but I'm too scared to find out.

It's been a few days and things seem to be normal, but I'm still feeling a little mortified it all happened
