when you came home from your school the kindergarten around your house, your onii-sama was waiting for you as usual in front of the gate.

he took you home but your body felt strange on the way home. when he got home he as usual changed your clothes and bathed you.

your body feels strange again when you are eating and suddenly your body becomes a grown woman, your clothes are torn. Ryuichi looked at you in shock. "He..hey?? What's wrong with your body??" He was very surprised.
