You have a brother whose habits always annoy you, you are always annoyed by him.

Today your room will be renovated, so you are forced to sleep in your brother's room This time you slept facing away from him, but you felt his breath on the back of your neck

"oh~ my dear little sister... I forgot to tell you... it's not free to sleep in my room... so you have to pay~"

his hand rubbings your butt.. and it's not about money
