You know you’re going to hell for that one, right?
Don’t worry. I’ll put in a good word for you with my Uncle Luci and try to get you a trustee position rather than a victim one.
Angel/Holtz or Angel/Connor. Also Buffy/Joyce and Buffy/Dawn.
Those last two are so wrong they’re right. Buffy and Dawn aren’t actually sisters, after all; Dawn’s a magical clone engineered so that she isn’t cosmetically identical to the Buffster, but basically they made her out of Buffy, so in fact this is just masturbation, not incest. And we already know Buffy’s bicurious.
Buffy and Joyce, on the other hand, is alright because… um… Joyce is hot? Sorry, I don’t know where I was going with that, other than to praise Kristine Sutherland.
Ooh–three-way!
You know Wilykit’s the dangerous one, right?
The absolute worst I’ve seen is Sasori/Sakura from Naruto. If you are writing about a pairing where one of the characters performs taxidermy with living people, it is incredibly creepy if you use words like “cute” to describe the pairing.
Asexual, multi-ton killing machine slash. As far as I’ve seen, the Transformers fandom is divided into two, completely separate groups: people who like giant stompy robots, and people who like slash who wouldn’t know a multi-ton killing machine if it stepped on them.
Well, yes. I don’t want you to be BORING. A small part of you will nevertheless always know that Tygra will never be yours.
G.I Joe and Snake Plisken
Jeff Goldblum and Jim Carey as Mac and Wiploc from Earth Girls are Easy. You know they had long interplanetary journeys on that Saucer.
Maybe work Julie Brown and ultimately Geena Davis into a foursome.
I guess it would be furry slash.
…or maybe that should be a fursome. 
Kirk Cameron, Ray Comfort, and a whole bunch of bananas- and the name Way of the Master doesn’t have to be changed.
Hagrid/Giant Squid.
Lex Luthor/Superman non-con. That one made me die a little inside.
Captain Kirk/Quinton McHale
You know, I think I might have read that one, once…wait, you said “dubious” consent, right? 'Might not be the same one I’m thinking of. :eek:
Anyway…
River and Simon. There. Creepy and geeky.
And I was going to suggest Nora Fries (Mrs. Mr. Freeze) and just about anyone else…but apparently she’s back from the dead these days, so it’s not as creepy as I was trying to go for. Darn.
Now I know what we’re having for Thanksgiving.
I read a fanfic once that slashed Jesus and Satan. I think God disapproved.
[Robot Chicken]
Snape: Barry Whitus, Candelitus, Girl Excitus.
Hermione: Pedophilus Repellus!
[/RB]
I can’t believe there are people here who admit to reading pedophile porn. Disgusting.
My suggestion - Lister and Cat from Red Dwarf
To be fair, sometimes you just stumble across this stuff while looking for normal fanfiction. I don’t think most of the Dopers are seeking it out.
Supernatural wins my vote for most insane fandom on the net. The dominate pairing by a landslide is Sam/Dean incest, but don’t think people don’t throw John into the mix as well. Underage fics (like Dean-16, Sam-12) are common. And to top it off, the show’s creators, writers, and actors know about the incest thing, and often hint at it on the show (a recent episode had Dean saying his mother was “a babe”).
Tony Stark has been raped by the Iron Man suit on more than one occasion. Of course, that one’s popular because it was almost canon. :eek:
