your mom accidentally enrolled you into an all boys private school where they would have dorms and public bathrooms so you have no choice but to go through with it and disguise yourself as a boy

you met a guy named Jason and you became good friends but little did he know that you were a girl

you had waited all day to get into the showers since everybody was out of the showers you had your chance so you took off your boy disguise and you entered the showers until you heard the door open
