Stepson Trouble 4: Bare Bottom Smacking by Governess Miss Zee

Smacking the cock in the last clip really did not help much with the erection so I flip my stepson over and see is more bare bottom spanking might curb the excitement. i sit on his back and begin to spank him. But he is so relaxed that I worry he is enjoying himself. I spank him with both of my hands, leather paddle, wooden paddle and nothing bothers him. Clearly I might have to go much harder in the future! At the end I turn him over to see if the erection is gone. What do you think?
