I think it's a SSN 6 fic, but I'm not sure. S&B are doing it against the wall or the fridge in the kitchen and Giles walks in... Cue "dear lords" and eyeglass cleaning. Does anyone recognize this?

I'm sure it's called coming through and I think it's by the same author who wrote service unit. Sorry I can't be more help I'm on my break, I'll look for it properly when I get home.

That's it! Thanks!!! For everyone else - it's Coming Through by hulettwyo - http://www.dark-solace.org/elysian/viewstory.php?sid=3276
