I met this girl at a party back in October, I could tell she was into me but I didn't find her all that attractive so I didn't try to do anything. This past weekend my boys and I had a party so I invited her to have more chicks over. As the party was starting and we had about 50 people over she noticed me and came up. She asked about my room so I took her there because the door is connected to the main living room and I wanted the other girls at the party to see me take her in there. We sat on the bed and chatted and I again intentionally made no moves. After about 15 minutes in my room, I wrapped it up and told her that I'm going to go talk to my boys so she would get away from me.

About 15 minutes later, she again comes up to me and introduces herself to the 4 friends I was talking with. We had over 100 people over, most of which were cute girls, so I wasn't too fond of this chick clinging to me. Unfortunately, shortly after, the cops came because of a noise complaint and 80% of the people left. At that point, between me being pretty drunk, this chick having her tits out, and me realizing that there weren't any baddies left, I decided to say fuck it and take her to my room again.

I escalated to fucking and right when we start she says something about her friends waiting for her. I just ignored it and carried on. She again brought up her friends once or twice and after about 20 minutes of fucking her hard she basically said to wrap it up. I told her we'll finish soon and tried to cum but I wasn't anywhere near ready and a minute later she essentially told me to stop and started to get dressed. I told her that I didn't finish yet but I didn't want to push it too much with the current social climate so I just got dressed too.

Between all the times I've been with a girl, I've never had something like this happen so I'm trying to wrap my head around it. Her friends really were waiting for her as they were the last ones left once the party died so I know she didn't make it up. I could also tell she was enjoying it but I also got the vibe that she was inexperienced so maybe she didn't realize how weird it was to just stop halfway.

Is this a matter of her not respecting me enough as an alpha and being that worried about her friends? I'd like to avoid this happening in the future so any insight would be appreciated
