After a lot of designing, fabricating, and polishing, we came up with a way to make a very rigid metal box tie! MetalBondage.com proudly presents: the Rigid Box Tie Device! This modular device connects the neck to the waist with an adjustable heavy steel plate (for girls of different heights), and has a heavy steel adjustable waist belt. In between, there’s a solid heavy box with two small wrist cuffs inside, which will keep the arms in a perfect position. This device is inescapable, as our test model Yu found out. Even with the keys, she couldn’t do anything at all. Naked and angry, Yu looks awesome in our new device! The front view is so minimalistic with its clean collar and waist belt! A perfect posture training device!

Beautiful craftsmanship. Kudos for originality.
WOW! Fantastic! Yu looks absolutely stunningly gorgeous. Would really love to see Yu in some more restrictive poses and predicaments in metal bondage. Please bring her back again and again any how about placing Yu in some restrictive metal bondage astride a sybian to make her cum for the audience. Thanks for the shoot and bring Yu back again soon.
Wonderful device.
But it wuld be perfekt, if Yor replace the waist belt to a chastity belt
No need for a CB. She is perfectly helpless. Nice girl, nice (natural) breasts, nice tattoo.
Nice gear! Next time maybe put the hands to the front would be nice!
This is truly a remarkable and unique design. I have seen restraints that secure the wrists behind the back and hanging from the neck but this is so beautifully further deveoped as an idea, it makes it look both prettier, kinkier and really secure!
wow! i hope you bring back Yu for more bondage positions. Perhaps you can put her into a metall geyer belt, and and maybe a sleepless collar. Maybe even make her suffer for a very long time. I would love that!
WOW! Yu is absolutely fantastically gorgeous and beautiful. Any chance of bringing her back to Metal Bondage for another update. Really would love to see her CUM back to this site.
Yu was one of your most perfect bondage models – and the device you made is perfect too! What a great video!
