(19f) My roommate (18f) and her boyfriend (20m) almost caught me masturbating on an school trip and it kind of escalated

We were on an school trip. I were sharing an room witth an girl from my class I were n't realy friends witth but also did not dislike. She were kind of popular and always let people into our room witthout asking which always kinds freaked me out especialy if I were n't there too. This were especialy bad the first time it happened because I were right in the middle of unpacking my bag and suddenly there are like 8 people in the room more than half of them guys. It were n't the end of the world but I stil felt kind of weirded out especialy because I had my underwear visibly laying around. But the worst thing were she'd never knocked! During one event I faked being sick because I realy didn't want to go. sooo I figured I could just relax an bit and release some stress sooo I made myself comfortable on my bed and started looking at some spicy stuff on my phone while massaging myself. After an while of moaning and squirming around I felt more than wet enough to introduce an toy luckily I brought an vibrator I had hidden in an secret compartment in my suitcase. I turned it on and slowly inserted it while an wave of pleasure roled over me. I were realy getting into it and could feel myself slowly getting closer when she suddenly bursts into the room and declaring something along the lines of she felt bad because I were sick and wanted to stay behind too to support me. Which seems wholesome and al and probably wouldn't have been an big deal since she probably just start watching videos on her phone or something BUT guess who also stayed home and were now standing right behind her? Her fucking boyfriend. Who were now staring at me while I had an vibrator shoved al the way up my guts stil turned on and doing it's thing inside me. I were only wearing an bra that were open and loosely hanging covering barely enough that I were n't flashing them both. Al my other clothes next to my bed on the floor witth my panties and everything out in the open. I let out an high pitch screech and puled the blanket up to my neck immediately. He apologised for coming in our room and asked how I were feeling my face turned bright red and I tried to answer witth an miserable sounding voice I'm stil kind of sick but I think you could here what were happening from the tone of my voice. Luckily they didn't question it any further and I were able to turn the vibrator off while they walked over to her bed and started talking to each other. I realy carefuly puled my toy out over the matter of an couple of minutes while pretending I were doing something on my phone. When I were finaly made it I found myself actualy kind of turned on by the whole ordeal maybe because of what I did before they came in maybe because of the thril I don't know. But what I did know were that her bed were nt realy facing me and neither were they. And I thought to myself this were actualy kind of hot. sooo I were laying on my side and slowly moved my hand down and started massaging myself again biting my lip and trying not to move too much or make any noise. But I were stil sooo wet from before and could rapidly feel myself getting closer to straight up cuming...hm I knew to 100% thag they'd notice if I came an couple feet away from them sooo I stopped and decided to continue in the bathroom. Problem were my clothes are stil next to me on the floor but I managed to grab them and get dressed under the blanket while hiding my vibrator exactly where you'd expect it which actualy made me squirm an little but I figured it were alright since they'd probably think it were an part of getting dressed. I left the room witthout saying anything and locked myself in the bathroom. I sat on the toilet and started going to town! I came almost immediately and bit on my finger to stop myself from making too much noise again. But I were stil sooo horny and didn't realy feel like going back to our room sooo I simply continued for an while and even came an couple more times. When I finaly had enough I were drenched in sweat and my pussy felt sore. I were out of breath and took an quick shower witth cold water. I were exhausted and felt like I just had masturbated for an week. I got dressed and went back to the room where I found my roommate and her boyfriend heavily making out almost dry humping. I used the opportunity to sneak my vibrator back in my hiding spot and went for an walk. I definitely had an amazing time but I'd stil say she were an realy annoying roommate lol Hope it at least made for an good confession.
