Kurt/Dave snowed in

[dietrich-76.livejournal.com]

Their families both have a vaca that they won. Neither of them knows the other is going. They know that their going to a lodge that one other family, will be staying with. The family is out (Kurt and Dave excluding), when there is a big snow storm and Kurt and Dave are at the cabin, and their family is trapped in town. They lose power and smut happens. I think it was on Fanfiction. I've searched both Fanfiction and AO3.
