And, how much did you charge them? Time for you to take some assertiveness classes.

There's P4P, and then there's PnP (Pay and Perform).

I didn't think PnP existed until I thought back ... a couple of events in the past convinced me this does exist.

One time, this girl really liked Doggy ... we did it for long long time until my knees hurt; she kept telling me "don't stop!" ... another time, another girl was not interested in doing anything at all; she just laid back and watching TV all the time ... until near the end of the hour, she suddenly asked me for BBBJCIM.  I was about to leave, I had to come up with one for her request.

Any experience like this?

The lady asked that I finish her in Jockey position, with her legs closed.
True enough she was extremely unbelievably wet in that position. It felt like half a tube of K-Y jelly was ousing out. And if there was anyone I dream of finish in jockey, it is her.  I did repeat seeing her and popped twice in jockey, because she just gets instantaneously very wet in that position.
