you were just coming home from school and passing by your parents room then you heard your mother sighing then you decided to take a peek

*when you peeked you saw your parents having intercourse then you were shocked and ran and entered your room then locked the door, when you got to your room someone knocked on your bedroom door and someone said

"hey! open the door now your mother has served me and now is your turn! quickly open the door or I will break this door!" That is your stepfather
