When a firmer approach is necessary, keep your sub in line with this adjustable wooden humbler. Your sub will be bent over and restrained, keeping him on his knees and completely submissive to you. The humbler is elegantly designed and shaped to fit snugly against the buttocks, using it as a base while the scrotum is stretched through the adjustable opening. Wing screws at each end of the humbler allow you to open and close it. If your unruly sub tries to stand up, the pull on his testicles intensifies and becomes noticeably painful. This will prevent him from standing and keep him bent forward. He will accept whatever you wish to give him. Is this a reward? This is your territory. You decide.
