I wish I could remember! I think maybe Star Trek: The Next Generation? (I had to go back and type that out, because I didn't know for sure if everyone knew what TNG stood for. Or ST:TNG.) I used to browse the archives of alt.tv.star-trek.creative looking for Crusher/Troi. But it could just as easily have been X-Files femslash. Early XF, when there were no significant non-related women on the show for Scully to sleep with other than Mulder's ex from that one ep, which I don't think anyone ever did anyway. It was all crossovers.
