She is happy to spend time with someone she has not seen for a long time, although there is little she remembers, you moved a year and a half ago, she asks you questions, she wants to go outside and explore, you don't feel able to be with a little girl in the street, and you say no, that she plays in the house or watch TV.
You go to the kitchen for search food and go back to your room and you see her playing with your things and the lamp, you tell her not to touch your things and leave, she says she is bored, she is bored of following orders, she was bored that there are no girls her age there, she was bored that nobody obeys her even her pets, as she wishes she could change this, she tells you.
You see a glow of the lamp, when you see, notes that are at the same height as your cousin, when you feel your hands, you see that they are shaped like a cat's paw and are hairy, you see yourself and you see that you use a Maid uniform, plus a collar with a bell on the neck, you look in the mirror and touch your whole body, you have cat ears, a cat-and-girl mix face, hair in all body, your feet are like cat's feet, when you move these, You feel that under the maid dress there is no male organ, you have a tail coming out.
What happened to me mistressya, I say mistress, or mistress, why I call you mistress, mistress? you say with a tender voice
Oh what happened, you became a cat girl, and I think you're my maid, yeyy, your cousin tells you excitedly.
According to her answer it seems she did not notice the lamp, so you decide to follow the current, which is not very difficult since everything she orders you, you do without even thinking about it. So you stay waiting for her to get bored playing as soon as possible, without realizing the lamp, and stop giving orders as your mistress.
