I'm not sure that it's possible, I was testing it out today with a medium punishment pins engaged. I was blown away by the fact that I was fairly easily able to push my penis completely out the back, because the flaccid penis is easy to squish and pull around it makes Houdini moves uncomplicated. I'm at the point now where I really think the only inescapable cage would probably be ones with a lockable PA. What are your thoughts? BTW because I found that I could get out of the device if I absolutely had to I've given the emergency key along with the original to my wife. So now there's seriously no escape, there's basically no way I could get back into the device once I've taken it off so now that shit just got real. 14 days is the longest my Master kept me in lockdown before, but now with a device that allows easy cleaning and breathing I could be in for a mighty long haul. Depends on if she wants the PIV.
