Ok, without pictures, I'll explain this as well as I can.

|___________/ | Arael Inside |
The idea here is simple. Arael was brought out blindfolded, so she had no idea "empty hole" existed at the time. She was put into the coffin, blindfolded, bound, and gagged... VERY lightly. The idea was for her to manage to struggle her way out of the bondage, gag, and blindfold within the first minute or two, while there was still plenty of air. A transmitter of a baby monitor was inside the coffin in the corner, so I was listening intently, planning to abort if she wasn't able to struggle out of the bonds within the first few minutes.
I was confident she'd be able to. I'd given her "practice" in the proceeding weeks, by putting her tight places and refusing to let her go when I was finished using her, instead making her work her own way free. The job I did on her today was little more than tying her hands behind her back with rope and putting on a ball gag.
So, once she got free, it was her role to start struggling and trying to escape, which she of course tried to do, scratching at the lid and heaving and screaming her lungs out.
I knew from a test run with myself in the box with no dirt that that the air in the coffin would, not run out, but become dangerously low-feeling after a little under twenty minutes. I decided to call it 18, just to be safe. Given that she was struggling and screaming, Cutting it in half seemed wise.
Finally, I knew from dry runs that I could reliably remove all the dirt and get the lid off in under 10 seconds thanks to the empty hole. For safety purposes, I decided to triple that, and add a second person to observe and assist, in case something happened to me or I needed help. To everything said and done, I came to about 8 minutes of her being buried.
That wasn't bad, but I felt I owed her more than that. The biggest problem was that there was actually significantly more air in the box than 8 minutes worth, but she couldn't get at it - it needed more air flow. I looked into adding an air tube down the coffin she could breath out of, but it was relatively ineffective. It was long enough that she would basically be sucking on her own exhaled air backflowing up the tube. We needed additional airflow. I added a second tube by her feet flowing out to where the empty space was, and that helped, but not enough. It only added about two minutes or so during my own test run before I started feeling low on air.
I stumbled upon the solution perfectly by accident when my friend went to go skiing in colorado and showed me this.

When I attached the carbon dioxide tube to the air tube in empty space, it literally doubled the time I was able to stay down there, at least. I say "at least" because I stopped the trial after about 40 minutes because I started getting claustraphic, and unlike Arael, I'm not the least bit claustrophobic. It enabled me to keep her under for a long enough time to make her fantasy come true, and it didn't even interfere with my plan to bury her naked.
So, in short, these were the safety precautions.
-An Avalung, to maximize the time she could spend buried and remain safe.
-Two air tubes, to increase circulation.
-A baby Monitor
a) She had an abort safeword
b) If I ever stopped hearing her for 15 seconds at a time, I would immediately free her
c) Every 4 minutes I asked if she still remembered her safeword
-An extra person in case anything happened topside
-Private property to avoid intrusion or interruption.
-Empty space to facilitate VERY rapid removal of dirt, while still allowing her to feel like she was buried under feet and feet of dirt (as she was)
and finally and most importantly
-a grand total of 11 dry runs and self tests, so I knew exactly what would happen and how it would go. Additionally, with numbers, I always rounded (extravagantly) for safely)
Vital Statistics -
She was buried for 18 minutes before I freed her.
She was buried under three and a quarter feet of dirt.
She got free of her bonds after 2 minutes, struggled to be set free for the next 3. After that, she started begging to be let out after 7 minutes, downright sobbing after 9 minutes. Her sobbing continued even while she thanked me and hugged me and did... other things after I let her out for the next half hour or so.
She told me "thank you for letting me live, master." Between that and telling me all the dirty things she would do to me willing if I let her out when she was begging, it was pretty much the hottest thing I've ever experienced.
