I was with one SP, who is kind of my go to, and I asked to do 69 with her for the first time. It got her attention, for sure (mostly because I had not shown any interest in that in the previous times we met.) After getting into position and getting into the action she seemed to really enjoy it, fake or not it was nice. Then she asked I would keep going on her for a bit and she would continue the BJ after, which was fine with me. She even turned off the music because she said she wanted to focus on that for a while. She let me know what she liked about it and told me a few times that I was pretty good at it, even though I had almost no practice.
It didn't really matter to me if she was lying or if she really enjoyed herself, at the time it made me feel good.
Damn, I really want to book with her again, soon.
