Hello, I'm looking for fics in where Buffy and Spike are caught in the act. Human or not, and preferably a long history. I hope for many suggestions, thanks!

In Heat by nautibitz

Just What is Real by Laure Alexander (v short though)

Nanny Spike and Aunt Buffy by Ravenesque

In the Bunnyverse I think it is in Heart Don't Lie by nautibitz that they are overheard.

Winters Storm by greyangel (they are overheard in this one)

Doing it for Daddy by Goldilocks (not available online but I have a copy in word if you pm me)

Want by Spikeschilde (v short again)

I'm just rereading the fabulous Yellow Brick Road series at the moment and they are caught in the act in the third in that series.

Yellow Brick Road series by Holly
A series rewriting Season 3, beginning with an alternate version of Season 3's Helpless, in which the Council locks a drugged and powerless Buffy in with a certain bleached-blond vampire who already has two Slayers under his belt. Continues there in unfolding Spike and Buffy's journey through acceptance, trust, and eventually love.

And of course there are the 'Where The Wild Things Are' rewrites which I think all have them walked in on.

Where The Wild Things Are by Jerzeyanjel
Another Riley free version of Where The Wild Things Are. Very smutty. And I mean very!! NC-17. Dont read if you cant handle!!

Possession by Ameeya (Holly)

Wild Things by nautibitz
Mid-Season 4, Buffy and Spike are compelled by forces beyond their control to get naked and do 'the wild thing' for hours... in Riley's bed. What will happen when they finally snap out of it?

Uncontrollable by sweetprincipale sequels Unmentionable and Unknown (WIP currently being written)
Set during S. 4"Where the Wild Things Are". Buffy and Spike end up being trapped in the Lowell House during the peak of the sexually driven "manifestation."

Thanks so much, i will read them all

You're very welcome and there are a lot of my favourites in there. What can I say, I'm a great big voyeur when Spike's involved.
