Try and cut a hole in her pocket and climb down from under her clothes. Shrunk in an Amusement Park chapter 6 by Louka31

You grip and tear at the material of the shirt trying to make an opening until sure enough, you make a small hole on the inside of her shirt. You poke your head through the hole and survey your surroundings.
You're head is pressed up against the cup of her black laced bra. Compared to you, its larger then life.
Looking down, you can make out her slender figure be hugged by the shirt.
Her shirt is tucked into her pants.
You hear a voice that startles you,

"Where do you think you're going? You're needed at the ferris wheel to relieve Tammy."

"But I just told Tim.." You hear your captur protest.

"Just get to it." The voice faded as you feel the woman groan and march towards what you assume to be the ferris wheel.

Now's your chance. You burrow and wiggle your way into her shirt and cling to her bra. You shimmy until you position yourself in between her giant boobs.
They feel so soft and warm to the touch, and it doesn't seem like she knows you escaped her pocket yet.
You decided its time for some payback. She won't be able to get to me without making a scene in public.
Now how should you enjoy yourself...?
