Definition - What does Arm Traps mean?
Arm traps refer to bondage devices that reduce a submissive's arm mobility. These usually place the arms in a “bent backwards” position. Arm traps are often made of metal. Some include leather sleeves designed to contain the arms. These devices are adjusted to fit the submissive through straps and clasps.
Kinkly explains Arm Traps
Arm traps are designed to be adjustable. So, they should fit most people. They can, however, become uncomfortable. As with all devices used in BDSM or sex play, it is important to agree on a safe word. Arm traps should be used conscientiously, such that the master pays attention to the comfort level of the submissive.
