My large facility fantasy

We would need to have some type of glory hole set up.
This glory hole set up would have to have the ability for the prisoner to hold your head in place or at least get fingers through outside of hole to hold your head in place so they could really feel like they are owning and controlling your mouth. Even better if there was a way I could move or turn so I could position myself best to take all of the cock… not hitting the back of my throat and leaving it hit like a bottom. The goal is, I want to make sure we can push all the way down my throat based on what they are working with.
I have this fantasy often and wish I could figure out a way to make it a reality. Certainly open to suggestions. Aside from hitting a police officer or doing something that lands me in jail.
The idea of having cell block after cell block make there way past my glory hole after the showers sounds like something I could commit to for a very long time.
Perhaps I could sell my soul to a prison warden or head guard some place.
I would gargle with peroxide followed by a real strong antiseptic mouthwash after each to try and minimize catching anything.
