Best FF Use of a Really Challenging Version of Hide and Seek: Hide and Seek, by jamjar. Eight Days of Luke, Luke/David. What do you mean you haven't read Eight Days of Luke? Go read it at once. I'll wait here.
All done? Then go read this story, which beautifully conveys the, um, special challenges of a relationship with a god.
Best FF That Proves You Don't Need a Vibrator When You've Got Flash: Face of Total Need, by Weirdness Magnet. Justice League, Superman/Flash. I never wanted to read a Superman slash story, because ew. I certainly never wanted to read a Superman with a sex toy story, because ew ew ew. But Weirdness Magnet wrote one so good I had to read it and like it, and don't think I don't resent it. This story has the perfect use of Flash's powers in a sexual scenario, and it left me giggling helplessly. Hee.
Best FF Featuring Some Serious Violations of Professional Ethics: Iris, by Janete. Alpha Flight, Northstar/Sasquatch. (Note: You can read this one without reading the books - I did - but if you have an urgent need to know more about the characters, click on the links.) I don't know what it is about the unholy combination of Jane St. Clair and Te that produces such excellent mutant sex stories, but I sure am grateful for it. Sasquatch's beast transformation may not be what he wants during sex, but it does make things interesting.
Best FF That Shows Us That Angels, Like Primates, Enjoy Social Grooming: Cumulative Effort, by magpie. Good Omens, Crowley/Aziraphale. See, with angels, it's all about making the effort. And once you get into the habit (no Satanic nun jokes, thank you), well... This one made me snicker. Quite a lot, really, and that's one of the reasons I'm reluctantly growing to love Good Omens FF.
Best FF That Follows the Noble Comic Book Tradition of the Angst-Ridden, Agonized Superhero, Although I Don't Think Even That Would Make Stan Lee Approve of This Story, Thank God: Perseus, Still, by Janete, the Amalgamated Queen of Mutant Sex. X-Men comics, Skin/Chamber. (Because it takes a special, twisted mind to keep up with the X-Men comicverse, links are to character bios.) We got yer mutant angst right here, folks, because these authors know that if there's anything more tormented than a teenager, it's gotta be a mutant teenager. This story has the most use of mutant powers during sex of any of these stories, and though you'd think it'd be vaguely oogy, it's so not.
Best FF Use of Various Orange-Based Beverages, Including Orange Julius, Which I Didn't Think Even Existed Anymore: Palooka, by Pares. The Sentinel, Jim/Blair. Jim's senses are, obviously, something most FF writers take into consideration when they're writing sex scenes, and frankly I have rarely seen any special ability so uniquely suited to bedroom activities. It's like the series creators said to themselves, gee, what combination of characters and traits could get us the most slash fiction in the least amount of time? And the answer was The Sentinel. But even in a fandom filled with mutant-sex stories, "Palooka" stands out, winning the "Phenomenal Use of Jim's Senses" special Sentinel slash award. (Of course there are special awards. I'll be doing a whole nominations set on them, just as soon as I figure out what the rest of them are.)
