I thought up a torture method U~U
it's basically social confinement but you are chained to the ground. you're wearing a choker that is just tight enough that it feels like it's suffocating you but it's not, on the choker there are keys, the keys are for the chains on your arms and legs. your arms are behind your back in a way that makes it so when you lean forward the keys dangle just over the key holes and so you need to dislocate several points in your arms in order to actually fit the key into the hole and even then you need to use your chin to actually unlock the chain, than rinse and repeat with the other leg, and eventually (more painfully) you get to you very dislocated arms, the pain would be immeasurable :)
