Unaware that she could….

So it was my second time doing oral on a girl. She was my gf,
She had reddish brown hair,freckles and blue eyes.
We both had a free day so we spent most of the day fucking. We had a long foreplay sess and she gave me oral… After that she slowly took off her panties to reveal that she had shaved. (I like them bald for oral.) Quite ignorant of how to do it, I just went for it and made up it as I went along… So I did oral on her slowly and I figured I’d get faster.
If she didn’t like it she was good at faking but, I kept going on her. I liked how wet she was. Then I figured I’d suck on her lips really hard. She doesn’t really moan but, she was moaning then.
Then all of the sudden I felt this snot like substance on my tongue… Pulled out and there was this white clear stuff.. I didn’t know vaginas could make snot. Oh sure I know what periods are but, snot? She looked at me and I looked at her not wanting to kill the mood I swallowed it and asked if she wanted more. She said yes and I gave her some more but, in my head I was wondering… “So girl cum is like this huh??? Wait what if its not…Is she gonna die? wait. I swallowed it.. Am I gonna die? and then finished the night with some anal. She liked anal more then vaginal penetration.
