I ended up having a girl come over to my place. She invited herself, which was cool. That's when the red flags started showing up. Conversation was chill and then turned into me hearing about her personal issues. Like how she was on antipsychotics and whatnot. Also my cat didn't like her. Now I may be silly about my cat, but my cat likes everybody. The last girl I dated my cat loved her. Wouldn't come near this one. The last girl my cat didn't like turned out to be beyond batshit crazy, so I value his opinion.

She had already told me she doesn't get along with any girls.

I almost told her to go home. But crazy is good in bed and I'm in a bit of a dry spell so I figure eh why not. Anyways we get to fooling around making out. She says we're not gonna have sex but we can fool around. That she's feeling selfish. (at this point she's mentioned to me that "I'm a tease").

I tell her I am selfish too, and that if I do her a favor I expect one in return. Migrate to the bed, I make the mistake of giving her hers before I get mine. I go down on her, and she tells me how good I am, oh my god your so hot, blah blah blah.

Finish up, fairly certain she came. Definitely seemed to enjoy it.

So, she puts my dick in her mouth for like ten seconds, before she tells me she doesn't want to do it because she doesn't feel comfortable. Told me she warned me she was a tease.

At this point, I've already ignored like five red flags and I really was not into being blue balled. So I told her she should go.

The expression on her face was pure shock and disbelief. She said we should finish watching the movie. So I told her, no, I don't want to. I told you if I'm doing you a favor I expect one in return. To which she responded "Oh, but you got to go down on me." I told her that it was fun but it doesn't do much for me.

That's when the hamster kicked on. "Oh but I didn't even come from it." (which is why you were telling me how good I was at eating you out.) I told her too bad for her I would have been more than happy to make it happen. I got some shit about "Oh sorry I'm not a slut" (You came over here and was more than happy to let me eat you out. The polite thing to do is give me some head in return.).

Then she left.

tl;dr Went down on a girl who was throwing red flags and was promised a blowjob in return. She refused to give me the blowjob so I kicked her out of my apartment.
