Dress-up

[killedkelly.livejournal.com]

I read this fic the other day that made me laugh, but I can't for the life of me remember where it was or who it was by. It was a fanged four bit, with Spike (William?) dressing up in Angelus' clothes as the older three vampires bathed and had sex. Angelus caught him in the act and was acting all nice and 'Daddy-like,' being all patient instead of ripping him to pieces. I remember that Angelus started treating him like a little kid, which freaked him out a lot. I think the older vampire bathed him then tried to take him temperature or something. That's all I can remember. Any help is appreciated.
Thanks! XD
