Actually, there are two different versions of Killing Time. The "slash" version made it into print, evidently by mistake, even after the "non-slash" version had been the one to receive editorial approval. I understand that there was a recall notice, but it wasn't sent to individual readers, just to bookstores, and so probably anybody who got theirs before the recall got the highly-collectible "slash" version. I've verified that mine is the "slash" version, and it's still very mild, compared to what, I'm told, is depicted in a typical "K/S" fanzine (or even compared with some of what I remember from Marshak & Culbreath's "Phoenix" novels).
David Gerrold also dropped an "f-bomb" in a nonfiction work, The Trouble with Tribbles, a chronicle of how that episode made it into television, in a passage explaining how he ended up making tribbles "bi-sexual, reproducing at will." Speaking of David Gerrold, I read his non-Trek novel, When HARLIE Was One, for a book report in high school, and it has very explicit sex scenes (not to mention drug use scenes, including depiction of joints being a commercial product, with brand names like "Highmaster").
