I Bare my bottom to be whipped by strict grandma

Grandma caught me diddling myself.
She told me to take of my pants and shorts.
I watched her bend over and reach into a bottom dresser drawer.
The sight of her white knickers got my winkie hard, again.

I bent over the bed.
My winkie went soft after first stroke of her whip across my buttocks.
After five strokes, I was sobbing.
She stopped at twenty.
She told me to strip naked and go stand in the corner.
