I would love rec's for any stories with intense unresolved sexual tension. It's okay weather or not it is resolved at some point in the story. Thank you so much!

Try out Whiskey & Wine by Mrs Muir. Its on her personal site. Sorry as guest I acnt post the link. Google 'whenbuffysmiles'

There is a lot of UST in this fic.

In the Army Now by Im_Bloody_English

Summary: Buffy joins the military and heads off to Basic Training. The Boot Camp experience can be rough enough to endure, but there's something, or rather someone that will make her time spent becoming a soldier ten times worse... a Drill Sergeant sent straight from the bowels of hell that takes an instant dislike to her mere presence, Spike. He's evil, he's mean, he hates her but even worse... he lusts for her.

I love a good UST story! I would love any other recs, too. A few came immediately to mind:

Denial by Enemy of Reality

Why We Fight by fer1213

Running Wild by dreamweaver

Dust and West of the Moon, East of the Sun by KnifeEdge also have a good deal

Hope those help! =)
