A boy that I was playing with asked to be hung by his ankles so that he could be used orally.
When a boy is hanging from the ceiling by his ankles, he feels vulnerable.
For these reasons, getting a boy up to the ceiling is therefor a worthwhile goal.
I decided to try this out on soundsFun. Making sure that the boy didn't fall seemed like the most important thing. I needed to prevent impact to the head and neck. I preferred to prevent rug burn.
I decided on the standard technique of using combat boots to spread the weight over feet and ankles. A couple loops of webbing and a couple climbing knots safely secured the ankles.
This left the two problems of getting the boy up and getting the boy down. I fantasized about this enough to have considered both up and down.
Getting the boy up I used a set of suspension mitts on his hands which I attached to the same clips as his ankles. Once he had been lifted, I unhooked these one at a time and lowered the arm (and the attached torso) down. After lowering the torso the hands are restrained behind the back.
Getting the boy down is actually a bit more tricky. Lowering onto the head or straight down the spine is really really bad. So I attached a quick hip harness and a single strap around the chest, This strap was then available to use as a handhold when I was lowering the boy after use.
The position is quite useful both before and after the wrists are released.
I revisited this position with lockedSteel during a research and development session. But this time I was better with climbing webbing
He reported that the suspension by ankles and wrists was comfortable. He said that suspension by just the ankles was strenuous, but fun.
