Predicament bondage
The person is tied in a way that if they move one way it causes discomfort somewhere else, so they have to choose their “predicament.” For example, tying someone’s hair to their hands – if they lower their arms, it pulls hair; if they keep arms up, they strain arms. Another: standing on tiptoe with a rope pulling their ankles up – if they lower heels, it tugs something uncomfortably. These scenarios are very BDSM-ish, creating a game of endurance. Definitely advanced and plan carefully so it’s challenging but not actually injurious.
