country club horror

it's the 70's. i'm with my best friend (who looks like me) and dad at a country club he belongs to. We're teenagers. Parents are divorced. We have long brown hair. Dad is golfing. We decide to go down to the pool. We are trying to decide if we are going to be "good girls" or not. We see a hot tub full of people and they ask us to join them. They are in their middle to late 30's and are all pretty weird (table 9). We get in the tub and they say "let's play a game, it's called #2". We realize it's a naughty game that you play with the person across the tub from you. Mine is some nasty lady. I get out of the tub and claim that I need to check in with my dad so he doesn't worry. My friend stays behind. Later I go back to our room to find my friends clothes on the floor so I assume she's been back for a bit. I see a door I didn't recognize before. A guy comes out of the door and he's bringing in power tools. I know he's going to hurt me. I try to sneak out and down the stairs. The janitor catches me and he's in on it. They drag me into the room and the guy says "do you know what a pinky promise is". I of course do, but am not sure what he means by it. He slices my pinkies with a razor blade and sews them both together. I pass out from the blood and pain. I wake up on some railroad tracks and I see my friends body. I'm pretty out of it but I manage to get up and start walking...then I wake up.
