In somebody's hand

When you open your eyes, you're being lightly squeezed, surrounded by something warm. Your eyes snap open, and you realize that you're in a big hand.

You look around, and see that the hand that's holding you is very fuzzy, with grey fur.

Your gaze follows the arm to the shoulder and you're met with an absolutely massive anthropomorphic mouse girl with thin limbs, small yet perky breasts, and big ears. She's so big, you'd only reach up to her shin if you were on the ground!

...Wait...

You glance around at your surroundings and realize that the mouse isn't massive- She's the size of a regular (if kinda short) human! You're just really small!

You look the mouse girl in the eyes. They look so familiar...

...

"...Squeaks?" You say hesitantly.

The mouse girl- Squeaks- Smiles and shouts out loud, "Yes! Yes! You got it!"

You blink at how happy she seems. It makes you smile a little too- At least until you remember your situation.

"Um... Squeaks..."

"Oh, yes?"

"Why am I tiny?"

"Oh, I made you like that! You're absolutely adorable like this!"

"...What."

"Oh yeah, I made you really small! 'Cause you're my pet human now! In fact, your whole family are my pets now!"

"...What."

"Yep! But you're special to me, so I'm gonna keep you with me!"

"...Wait wait wait, what do you mean, we're your pets!?"

"...That's... Exactly what I mean?" Squeaks tilts her head in confusion. It would be cute in any other situation.

"But- But what if I don't want to be your pet!?"

"...Um... I'm not sure. I don't think you get to choose."

"Says who!?"

"I dunno." Then, she shakes her head. "But that's not important right now! What's important is this!"
