Humiliation

I didn't really understand why I was here....my wife sat on the edge of the tub and I knelt by her side as we both watched her lover shave all around his cock and balls!!!
I had initially thought she was going to make me shave him for her....she had done that before and I had told her just how humiliating it was...
But she said nothing as we both watched....
When he was smooth he handed me the razor....and then he turned around!!!
"Lather him up Sissy," my wife said, "You'll be taking care of the rest!!!"
I stared at the razor and wished I could fall through the floor....
