Vampire Mansion

“You are going to visit your family after some time, everything is ordinary except for the fact that they are all vampires, your father is the alpha vampire, the same as your mother. You have four siblings, Emily, Ethan, Kyle and Vanessa, all over a century old. You are the youngest, and surprisingly you were born as an ordinary human. You are fifteen years old, your parents invited you personally. You ring the doorbell and your mother comes to greet you.”
