The next day you wake up tired of having played many girlish things, when you do you see the room the same, but smaller or you are bigger, you think you returned to normal and you go to the mirror, but you look disappointed, you are still a girl, but now a teenager, your hair tied like 2 long pigtails, you feel somewhat grateful since you don't have big breasts, which would make you nervous.
That time a teenage girl with cat ears and pink hair enters, remember, she is your cousin in your converted body and now as a teen, you talk to her and ask for an explanation of what happened.
You see, I woke up early, you were so nice to me, despite what happened, giving me an excellent day so I wanted you to have a good day today with me again, and since I heard you not like being a little girl, maybe be older you like, also I would like to be older, but not so much, I do not want to lose all my childhood, so I managed to enter my mother's room and use the lamp so that today we can spend it like a sleepover of big girls to your taste; you hear something angry about what she did, you tell her that you spend this with her, but as a guy, then she responds that because of the brightness after the desire, her mother noticed, she took the lamp from her, left it in her room under lock and threw her out of there, and that she is not allowed to play in her room because she is her niece, and that she would only return her to you,her daughter, and left.
You turn something happy, and angry and go to your room with her, you sit in an armchair and you start playing video games with your cousin, on this girl's day.
