okay, so this was a SUPER lemon fic that I'm trying to remember. The idea was that Sesshoumaru got cursed to freeze to death by a jilted demoness. Kagome runs into him (avoiding a blizzard) and they're both trapped in a cave until the weather clears. They end up in several chapters of smutty/lemony goodness, because that kept Kagome warm and stalled the curse on him.

It ended with Sesshoumaru killing the demon that cursed him, Inuyasha attacking Kagome for her 'betrayal', and for a reason I don't recall they erased memories of the incident from everyone except Miroku and maybe Sesshoumaru...? I really enjoyed it, there was supposed to be a sequel story but I never read it...

I think you're looking for Oroyukae's Not Impervious

He was supposed to be the most powerful demon in existence; one that none could best in any situation, at any time. That was not entirely accurate, it would seem. One error in judgment at the most vulnerable of times, and all that he knows lay in jeopardy. Just what would said being be willing to agree to in the direst of circumstances?
