I was lucky enough to have a girl let me learn how to do this with her body. She had never done it before, so was really nervous about it the first few times we tried. She also said it made her feel like peeing. It helped out lot when I would lick her clit as I was stimulated her insides. That seemed to be enough sensations she just let go and didn't care what the outcome was going to be. I got a really wet face after that
hers tasted sweet. I might just be lucky but I haven't been with a single woman who had a foul odor or taste.
