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 bathroom 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 asks that she would like to be bigger, and that you be younger like when you lived in his house, and that both have fun and play being very beautiful.
You see that the lamp gives a shine and then you see that your cousin begins to grow, her body develops until she has the body of a 15 years old, her clothes adapt to her new body, and strangely a tail and ears of animal grow, you shrink a little and your age is the same as her, your body feels weaker, thinner, smaller than before, but then you feel 2 mounds appear on your chest, you touch them and you feel they are 2 breasts, you touch your crotch and you feel the absence of your male organ, your clothes become a bit feminized and your pants become a skirt, just like a tail and cat ears, around it changes and you see that you are no longer in your room, but in a more feminine one, you see Through the window, and you recognize the outside you are in your parents' house, as it is ordered, it seems that you live here, you feel scared about what happened, suddenly being a teen catgirl, you never thought something like this would happen.
Your cousin is happy for what happened, she starts dancing, singing, she wants you to be happy just the same, but you still look surprised, she grabs a purse and puts you on, combs you with 2 hair leagues, making you 2 pigtails, grab 2 strange dolls, place one in your purse and start playing with the other, you just stare at it with your face, now a little disgusted and half angry.
