They work together to do chores for a larger mistress who isn't mean to them but who is a few sandwiches short of a picnic in the head.

But they are both stuck in this small white space. There is nothing but them there.

The mistress reaches in and picks them up out of the White Room with black curtains near the station. Turns out they were in this subspace slacking on their duties.

Nope sorry, theyx are still stuck in this tiny white space. Buty anything can happen to them in there.

Hehe, Or perhaps Mary Ann slowly become more of a arstocratic lady, eventually becoming Mariechen's new mistress. Complete with some height growth and hourglass expansion for Mary-Ann? :3

Thats something we can work to. ^^

Yeah and her Maid's Dress becomes more fancy and puffy too. XD

Maybe she ends up taller than Mariechen, as a bit of a silly height "Role Reversal". XD

That may be a thing I leave up to choice.

Quite the delight to see these two together, and though both seem a little awkward in one another's presence ( which yeah, I get, especially Mary-Ann's concerns~), and I am curious what will happen to the pair of maids in this out-of-space/time/context bubble of non-reality...though I recall some fun shenanigans with a certain pair of wabbit women some time ago (*sing song* ~Con-Tin-Nui-Ty, BOOM!~).

Though if I were to make a suggestion (although, my bias is likely to show though), I'd imagine they might get hungry after awhile, and perhaps some tucked away nibbles in apron pockets to tide their hunger...of course, Mary-Ann's snuck-in snacks would be from Wonderland and depending on the nibbles or drinks (which I imagine normally Mary-Ann would know better to eat random food from Wonderland given well, Wonderland, but desperate times...), likely lead to sudden changes in size which could likely make things worse, but such 'little problems' (Ah Shrinking puns~) could help break the ice a bit better and they come out better friends =D. Well, maybe...depends on where things go and whatever puppet master behind this decides to get more involved or pull more folks into the exchange. Either way, I'm quite intrigued where it'll go next =D Even over in Patreon~

Thank you! Yeah, was thinking about some size stuff.
Maybe I´ll do something multiple chioce that may turn into a CYOA.

Oh, that'd be fun =D!

A box of cleaning supplies lands near them.

What are they going to clean? They have to open the box and inspect the contents to puzzle it out.

If they don't the white space will just stay the same, and the box will just sit there.

Interesting! That goes to the list!

A growing kitty. She reminds me of previous ginger kitties in your character roster or line up.

I have a thing for cute kitty cats.
