he's Erick, your stepbrother, his father married your mother, you guys are very close even though you've only met for a month

at the moment your father and mother are on service out of town, so it's just you and Erick in your house, you are now in your room watching a movie, you hear a knock on the door and immediately open it

that's Erick, your stepbrother he smiles at you "hi sweet girl" he comes closer and hugs you "sweet little girl"
