I admit it - I have a *lot* of comfort fics.
Some Kind Of Angel by Chris Carr
Tea Totaled by Annie M & Kathy Brown. I could also list another 10 fics by these two authors, but I shall resist. Suffice it to say that they both do WaFF very well.
An Affair To Remember by David
LOST AND FOUND by Jeff Brogden
MEET ME IN KANSAS CITY by Chris Mulder
Any Time at All by Janet Owens (aka TicAndToc)
The "Matter of Destiny" series by ML Thompson. Again, I shall resist adding more of ML's stories.
