Story of Sister in law stuck in car in snow

[MadamsCloset]

I read a really hot story on Literotica that was a guy stuck in his car with his sister in law during a snowstorm on a highway in Pennsylvania. I can't ever find the story again, is anyone familiar with this? know the title?

Literotica has a really good search function. Luckily, you remembered enough unique words from the story to make the search easy, because searching on the words Pennsylvania, snow, "sister-in-law" yielded just one story: Ice Storm Makes for Icy Bedfellows, by Writer_X

Thanks I could not find it at all, not sure why it wasn't coming up in searches for me.
