She is happy to spend time with someone she has not seen for a long time and be in your house, 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 outside a few minutes 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 and say I wish I had some stuffed animals to play and that are magical so you can play like me; suddenly the lamp gave a shine and 2 plush animals appeared, one of 1 pink cat, another of 1 green rabbit.
She is going to grab the rabbit and starts playing with it, she wants you to join her so she throws you with the stuffed cat, you grab it and examine it, you stop watching it and you see your cousin her hair seems to be a little longer and something comes out of her head, rabbit ears, you tell her what you see and she is surprised at this, then she laughs and tells you that the same thing happens to you, you go to the mirror and you see your long pink hair , cat ears appear to you, but something else happens to you, you start to shrink until you reach the same height as your cousin, your body is weaker and softer than when you were that age, when your clothes change also becoming a children's dress , long pink stockings, feminine underwear that when you feel it you notice the absence of a lump, you give a childish cry and you start talking to your cousin.
In this children's discussion at one point you tell her who will take care of things and explain what happened if an adult arrives, she responds that she wishes she could take charge, you observe that she was still holding the lamp and it shines again.
Your cousin begins to grow until she will the age you were, with a developed female body and her clothes adapt to it, she is glad of this, while the lamp stops working, you make a sad and angry girl face.
You get tired of reneging, she tries to calm you down with some concern, knowing what she did, causing you to get on her legs, you just remain angry and worried that you will do now.
