A while back, you were kidnapped and sold into human traficking. You were shrunk to the size of an ant and auctioned off to a new owner.
Your owner is a very rich woman. She's owned tiny slaves before, but when you're brought to her mansion in a box, she drops a bomb... she squished them all under her feet for underperforming or displeasing her. And she will do the same to you if you mess up.
She made you serve her feet and worship them. Occasionally she'd make you worship her girl friends's feet whenever she had them over. You managed several months without making a mistake once...until now. Earlier, she ordered you to lick her sweaty soles clean, but she wanted it done in an unreasonable amount of time; only 5 minutes. Obviously you couldn't clean her feet in such little time, but she didn't care. You failed her and that was an excuse for her to get rid of you. You run as fast as you can and manage to slip into the shaggy carpet in her bedroom. She's not worried though. She locks the door behind her and sits on her "throne", a comfortable, cushiony chair decorated with all sorts of precious metals. She begins brushing her feet along the carpet fibers, trying to feel you wherever you are in the carpet, looking for you. You're trapped in this room with her.
