5 other girls

You gasp when you see the room. It could've been an average living room, if it wasn't for the bodies of five limp girls in the center. All of them were hanging from rafters by ropes tied to their hands. They were in various states of undress. All of them were around your age. At your intrusion, four of them looked up. The last girl just hung there, possibly dead. The son shoved you forward. You stumble, but recover. The father reaches into the pack behind him and pulls out a rope. You struggle slightly, but freeze when the father pulls out his gun. The son finishes tying you up and watches you.
