Keep him on his knees where he belongs with The Humbler! This wooden bondage clamp grabs his balls and pulls them back between his legs, hurting him a lot if he tries to straighten when bent over, or tries to stand when kneeling…

I think the Hanson Humbler is the gold standard. The hinges are hidden, it latches closed without having to turn wingnuts and/or locks. The lock is very quick and easy to disengage.
