Story about a family that goes on vacation to a cabin at a lake. Father, Mother, 3 daughters, and a son. The basic story; The extremely controlling mother plans the vacation entirely, and insists on doing all of the packing herself, to set up everything else. Everyone ends up with no underwear at all, and all of the girls clothes are extremely revealing. The cabin ends up being a single room with 2 large beds, and all 4 of the kids (between 12 and 17 iirc) are forced to sleep in the same bed, while their parents are in the other bed having sex half the night. At some point the only underwear the girls have turns out to be single use disposable panties that get destroyed in the washing machine at the cabin. In the end, the brother nails both of the older sisters, and the father does the youngest with the mother's encouragement. All of the girls end up pregnant, and the mother blames it all on the kids.
I think this was first found on ASSTR, but I can't find it anywhere.
