The start of thiis video looked like a guy trying unsuccessfully to play the drums. The three females clearly thought they should have been served pizza while going through this charade. Absolutely pityful.
Those gals should be bare ass naked for each and every swat. I would give a slower pace with a harder swat so that each one is a fresh explosion of pain against her naked rump.
The facial expressions on the girl in the white shirt reminds me of the girl's comment in Slumber Party 57 regarding when her dad spanked her. "It kinda hurt, and it kinds felt good."
