When Mistress Anouk and Princess Marilyn find their slave only responds well after being slapped, they put him on a slap therapy schedule. They both take their time slapping him. They slap him brutally and consistently. They want him to know they expect his best behavior and when he doesn't perform, there will be harsher punishments. They stand him up and slap him for what seems like hours and then allow him to go on with his day when they are done.
