Wrists over Head to Back [Level 1]
Notes and Resources:
This is a quick, easy, and very sexy tie. It's one of my favourite ways to start a bedroom bondage session.
As I mention in the video, this works best as a short-term position. A lot of people will have their arms start to lose circulation just from being pulled up and back, especially if you tie it tight enough to be inescapable (which is difficult or impossible on many people). If you tie it more loosely, they'll tend to be able to lower their elbows, and/or poke their head under an elbow to get their wrists some freedom of movement.
To use this as a longer-term position, pull the wrists back not to the very limit of flexibility, and then add rope around the arms that fills up the space under the elbow that the head could otherwise go through.
