Peter Parker in Sunnydale

[ladyhatshepsut.livejournal.com]

I'm looking for a story where Peter Parker, aka Spiderman, falls through through a rift in space and lands in Sunnydale. He meets Xander and Spike first and gets along with them but Buffy and the other have a very snide and suspicious attitude toward him. He makes up another batch of his web fluid and helps the gang capture a tribe of demons. Peter ends up going to L.A. and Angel's with Spike and Xander. It's Xander/Spike/Peter. I thought is was called Dimensionally Challenged but can't find that title anywhere.
