searching for spuffy fic where they visit hell dimension

hi im looking for a spuffy fic where some demons are trying to go through the hellmouth so they can get home. buffy doesnt kil them cos they arent hurting anyone. dont remember how she got there but she is in hell but not being tortured or anything like that instead she makes friends with female demon. towards the end of the fics her demon friend is getting married and buffy is her maid of honor and spike is the grooms best man

I believe that's To Hell and Back by Palerider: http://spikeluver.com/SpuffyRealm/viewstory.php?sid=3048&warning=NC-17

ya thats it thanks
