Every slave slut must be properly trained to worship her Master's cock. She must do it without her hands, but only with her mouth and throat. A slut must be able to keep a cock in her throat for as long as her Master wants it. If the bitch is not trying hard enough during training, she should be encouraged with hard face slaps. Of course, cock worship also includes aftercare, since the Master unloads his jizz down the slut's throat.
