I oooh and aaah and moan away...but think about what I'm going to eat for dinner, what I'm going to buy with the money, what I'm going to do the next day...all sorts really!
Last night I was with a client, that I'd say was a very experienced client - lots of feedback and lots of stories about having seen all different types of girls. He wanted 69, and clearly thought he was amazing at it. I kept thinking he will find my clit eventually, but no - he was closer to my thigh! In the end I went for it and pretended to cum - well he'd tried so hard he deserved something! And during this, like you, I was debating what to have for dinner!
