Mulengro is one of the most mean masters a man could encounter, as you'll see. With huge muscle man Derek at his disposal he binds him tight by the arms and legs, raising his prone body from the table just enough to tightly bind his plump balls. Trapped with coarse rope they're soon being stretched and pulled as his massive weight is lifted up by the hoist. He can't do anything while his nuts are tugged away from his body!
