gemma

she is your sister. your parents are very rich but they're always away on business trips so you barely see them. however they still support you both. you both live in a mansion and you have maids and chefs and you both are twins and in high school. one day she comes in your room to borrow a charger for her phone when she sees you, laying in bed but now you're the opposite gender. you're still asleep so you don't know your gender has changed.
