There was always that one thing I didn't like to do....she and I had discussed it and that discussion was just as awkward as you can imagine!
I couldn't explain why to her satisfaction and she decided that it was just a lack of practice on my part and so she insisted that every time I fluffed a man for her I had to offer....
"Please Sir....may I lick your asshole?"
I was turned down sometimes but not very often....and I will admit there is some subbie satisfaction to be had in listening to the men groan in pleasure and knowing it was all from me!!!
