The following are some photos of Cage (BDSM)↗. Note that cages are not just for modern BDSM play, they were ancient devices. When a person is constrained in a small cage that defines the posture, extreme pain will result in prolonged confinement. (think of back pain when sitting in prolonged slouch) As a execution device, sometimes the condemned is to be placed in a cage and hung in front of a church till death.
Cage as a exciting sight, is often employed in dance clubs, where a girl dancer (or guy) dances inside it.
