Stripped and spanked OTK in a friend's house kitchen.

One time, at a friend's house, she looked at me sternly and said, "Follow me into the kitchen."
There, she said, "Get naked." 
Then I saw the big brush in her hand.
I stripped, and went over her lap.

It didn't take long for her friends to come in, to see what all the noise was, and they stood and watched the whole painful session.
