Roommate argument

So last night I took a shower at like 12:30 am and when I got out my roommate had come back after being at her bf’s dorm all day with her bf but I didn’t think anything of it bc they’re a couple and I’m really cool with both of them so I was like whatever. Turns out they came to the room bc his roommate started jerking off while they were still in the room (it was kinda funny we all laughed) and then we played uno on iMessage games until like 2 when he started falling asleep. It was fine until this morning. I woke up to her bf’s alarm and this man didn’t wake up and neither did her and it was so loud. Our suitemate texted me like who’s alarm was going off (she’s in the room next to us) and I told her it was my roommates bf so I got up turned it off and then 2 minutes later his next alarm went off so I got up and shook him and I was like your alarm is going off. He mumbled something and I went back to sleep. I woke up like an hour later bc my roommate and him were snoring (we all snore so we call our room the lions den). I got up and peed and I came back to try to go to sleep but I couldn’t so I was watching TikToks and then out of nowhere I hear like wet slapping noises and moaning and I was like oh hell nah so I didn’t even bother to turn around (I was facing the wall) and I waited for the noise to stop but I was literally watching TikToks like it was obvious I was awake. After a couple minutes the noise stopped so I got up got my stuff and got ready as fast as I could so I could leave. My class doesn’t start until 11:10 (I left around 9:45) but I wasn’t about to be in the room while they were having sex. Around 20 minutes after I left my roommate texted me asking where I was (we have the same class) and this is what I said:

(Sparrow is her pet rabbit) (she took a ss of our convo and sent it to her bf)

I was telling my other suitemate about it and she said people make sex noises in their sleep all the time, which I know, but literally the sound of wet skin slapping??? That is a pure sex noise not no sleep noise. She swears that they didn’t do anything but I promise that I heard sex noises bc as soon as I heard it I paused the TikTok I was watching to make sure it wasn’t the TikTok. It wasn’t the rabbit making a noise either and it wasn’t the room next to us because it sounded so close. I wasn’t mad, I was cranky and irritated. Idk whether to believe her or not and to make things worse she has been mad at me and our suitemate Alyssa all day because we don’t believe that her and her bf didn’t do anything while I was in the room.
