I think you'll find that the anal sphincter closes up tight during sleep (that's it's resting position) and that this can be quite painful when you are plugged.
The rectum also dries out during sleep, adding to the discomfort.
Personally I find the best stretching device is a set of fingers - they come in 5 handy graduations, and if they're attached to a suitable human being they adjust perfectly to all requirements!
This is one of my most favourite games to play with my partners in bed (with their prior standing permission). See how far I can get before they wake up.

(and then it turns into me getting them off by finding their g spot from the back... so a pretty good deal all round as it gets me off, if we don't just get more serious than that

).
As for dryness, a thick lube that doenst dry out (vaseline isnt great... coconut oil too thin...) would be good. Probe thick is pretty good, but I wish it was thicker (seems thinner these days and super hard to find). When you first put a bit of soap on it to wash it off damn stuff is slipperier than wet ice on teflon -- and sticks in strands like natural thick mucus, wont wash off readily -- or wear away (wish it was that slippery during normal use! I've tried it with the slightest hint of soap, but it still irritates). Some chemist needs to get on top of that and make a bundle in the 'serious about anal' market. (ie this website

)
As for the sphincter + air to inflate a dildo, I've had an inflatable dildo that wasnt like these cheap ones you get these days that are as thin as a baloon - it was much thicker material, and I dont know if they had longitudonal 'ribs' inside it or somehow the construction of the material, but it inflated pretty evenly for the most part. It was really great, I should get another for training my girls

Unfortunately the darn hose shore off the edge cuz of various pressure from use (they never put the hose on the side, but on the end, so you cant sit on it, duh).
Also, I cant be awake ALL night training them you know, gotta rest up for the next day's activities!
