giles is buffy and dawns uncle

I read a fix here , where Buffy is on her way to her uncle Giles house in London I believe. She hits spikes car I think. And they are stranded and hook up. The next day. Duffy goes to her uncle s and see that Giles buisness friend is spike so she pretends she's engaged to dawns fiance. Spike then finds out and plays a trick in her. That's all I remember.

Is it Into the Storm by Katrina

I think this is what you want:

Buffy is Giles' niece/Make love in his car for body heat

I read a fic a while back where Spike and Buffy meet for the first time when they are driving both driving during a snow storm. Spike saves Buffy and they end up having making love in his car for body heat because the plow can't get through. Buffy's a virgin. Giles is Buffy's uncle and Spike comes to stay with them as an English professor, I think. Buffy is staying with Giles to help him write his newest book by typing up his notes.

Thoughts?
