So, about two weeks ago, I stumbled upon FetishFad's "Annex". For the first few minutes, I thought it was just special effects or second-skin-suits, but I looked into it, did some research, and learned about the body's actual inflatable capacity. Doing some more research, I also heard of a lot of "health risks" and "safety precautions" and "training methods" that one has to attempt before inflating.
What are these? Is there a handy little pamphlet anyone has a link to?
