Diane ties me to a bench 8

One evening, I arrived at her place.
She looked at me through squinted eyes and asked, "Did you masturbate today?"
"Uh...yes...."
"I cannot tolerate that behavior.  I will let you off with half a punishment, for admitting it, but you will be punished. Strip, naked."
I did and she led me to a bench, had me lie down on it, and tied me down, and 

I moaned and sobbed as the cane struck my buttocks.
