Vore and I have a strange relationship. It pushes certain buttons pretty hard, but only in VERY specific circumstances. Vore with finality pushes a completely different set of buttons, my violent protective berserker buttons, and is generally bad, but if it's harmless and fun I can enjoy it. But the kind I really like? Remarkably rare, I've found. Everyone's about the gurgly murder fantasy, when what really pushes my buttons is casual use and lewd exploration. Sexual junglegym, inside and out. I've even got an as-yet-undrawn character JUST for satisfying the urges
Impossible strength. Incredible capacities (Stomach and otherwise), and general occasionally lewd utility push the powergaming buttons in me for their sheer possibilities that never get utilized.
Utility vore. From my lewd burd-in-progress able to move an entire apartment via single-seat motorcycle without any difficulty, to the parent with a utility space to send kids to time-out or for bed if they're out and about late, to casual lewd carriage of goods without pockets or packs. Internal explorations that don't digest you, they're just warm and soft and cozy. It isn't just vore, it's object or people storage/stuffing in general
made a pair of pocket goblins to push these particular buttons for me as well (also a different, goblin related set of buttons, but that's neither here nor there). Well trained, enchanted tummies, with cute little bottomheavy owners to follow you around like the most spacious purse/arm candy ever.
I rather like this as well, the idea of being able to hide someone or something much bigger than you'd imagine being able to be held on, or in this case, IN, someone else. Sometimes in a lewd fashion such as cock or anal vore that is notibly pleasurable at times, but just to hold or carry people or objects. Like the example you gave to hold naughty children in time-out for a length of time. It's a very fun concept and one that's not explored too often, though I've found a smattering of instances of it here and there.
