Head Sitting with Goddess Samantha

A true slave makes himself useful. Goddess Samantha particularly enjoys slaves who can serve as her human furniture. Specifically, the strong and silent type that can serve as her human stool or chair. Often she enjoys sitting on them for hours and doesn't want any noises or whining or complaining to distract her. Goddess Samantha demonstrates how this can be done, as she sits full weight on her slave's head for almost 5 minutes. Can you pass the test and become Goddess Samantha's human furniture? Can you last even a minute under her magnificent ass?
