Xander takes advantage of weakened Buffy and Spikes finds out.

This has been bugging me. I read this a while ago, Spike is a vampire and Bufy is the slayer. I think ts set after the Spike/Anya thug but I could be wrong. I remember Buffy and Xander hanging out, possibly drinking, and Xander gets it in his head that she wants him or something and ends up forcing her. She's to drunk or weak to fight him off. I think Spike sees her crying and finds it, I can't for the life of me remember what happens after that. I think it was on a diff site but I could be wrong.

It is a buffymeetspike story at the bloodshedverse.

Destroying Entropy by BuffyMeetsSpike
Goes off canon in the middle of Entropy. Buffy goes to check on Xander after the confrontation outside the Magic Box, and she finds her world shaken to the core by what ensues. Will Spike be able to help her pick up the pieces, or has Buffy finally gone over the edge?

This is it thanks guys! So many fanfic sites to keep track of.. Lol.
