I 20[M] go down on girl on a couch in front of other people [MF]

So title kind of says it all, granted…but how about I fill in a few more details.
Her name was Pira. I knew her through my work study job in the dining hall. She was a little trailer trashy and people made jokes about how she was slutty. But they had no evidence except for the way she dressed, I guess. She had dirt curly blonde hair and a tattoo on one arm. I didn’t care if she was a slut or not, was focused on other girls at the time. I still wanted to get with her though. She and I got into this thing where we gave each other a different kind of high five whenever we passed in the halls. I came up with some good high fives. Made her laugh. So that was the beginning of it I guess.
Later I ran into her at this house party off campus. Actually she ran in to me. Came up and put her hands on my shoulders and made me spill my beer. She was super apologetic and it gave me the upper hand on things that night. So just get into a situation where a hot girl makes you spill your beer and you’ll be fine or something lol.
We hung out with a couple of her friends, drank more and smoked some of my weed. We ended up making out in the kitchen, awkwardly against the counter. Then I said we should get out of there and she agreed but was pretty out of it…eyes glazed, body-tired. So we sat down on the nearest couch–by now its the end of the party and people have either mostly gone home or to sleep- and just cuddled for a while. At some point I thought fuck it, nobody’s watching and I’m bored, let’s just hook up on this couch. I was concerned that she’d fallen asleep on my arm, but when I kissed her she made an humming sound and said “right here?” I asked if that was cool and she said “Uh…whatever?” And laughed. We made out on the couch, me on top, and I moved down her neck and her chest. No real plan here, just seeing how far we could go. I made my way down to her bellybutton and unbuckled her belt and her pants. Worked my hand around her mound on the outside of her underwear. She panted and chuckled some. I fingered her for real for a while before going down on her. Her top was still on…her pants were just completely off. Rubbing against my neck while I pleasured her.
Pira rubbed at my head and made fluttery moaning sounds while I licked and fingered and…this might sound ridiclous, I know, but it was only when I came up for air to get a better position that I realized there were actually other people in the room. As in, those mounds of sleeping bags off in the corner actually were people sleeping. I know because I saw one of them move. It freaked me out for a second…I looked at Pira and her eyes were shut and she seemed to have no idea. So I just thought, K, whatever, they’ll never know. And dove back between her legs. She rubbed the back of my head and got wetter and moved her legs around. I changed my tongue up from sides to sides to ups and downs. Finally she said “fuck fuck fuuuucck…” and she twisted around on the couch and her legs drew together. And almost at the same time I heard some dude say, “what the fuck…I can’t believe you guys. Get out of here.”
Then Pira was suddenly alert to the situation and got up and said “Oh my god…what?!” Pretty loudly. She got dressed and I went out with her and said I didn’t know there was someone there…she said it’s cool, I know, it’s cool, I just want to get home now. I offered to take her home and she declined.
Do I feel a little weird about this? Yes. Was it still kind of funny? Yes. Have I told people about it? Not
