“Ow!” he yelled, as he felt a sharp smack–much harder this time–on his bottom. He involuntarily released his knees in defense, and his legs straightened to protect himself.
“When I ask you to do something, I expect you to listen. That is the second time you…”
She trailed off when she saw his stiff penis bobbing up and down. He tried to cover himself with his hands, pulling his knees together as well.
