For some of my subs, a simple rest sack is not enough. Some of my subs need more secure bondage of which I am happy to provide. In the case of this one, he required a leather rest sack, numerous leather belts up and down his body and finally, a big heavy metal chain running from head to toe with pad locks affixed to each and every belt buckle. Only the person with the key can let me him out now, and that person is me. Personally, I prefer to leave him right where he is.
