I'm using the term "sexpollen" pretty loosely here. The following links are pretty much everything from literal sexpollen to other varieties of fuck-or-die fic. Supernatural roofies, gnomes made them do it, you name it. Pretty much the only thing I'm not including is Pon Farr fic, since I figure eventually that will get a master post of its own.
Star Trek XI
Yellow (LJ Mirror)
By: entanglednow
Info: Kirk/Spock, NC-17, 2840 words
Summary: He prods the foliage to his left, which reacts in surprise by flinging pollen everywhere, and the air is suddenly ever so slightly more yellow than before. Which he figures, in hindsight, probably wasn't the best idea.
Notes: Hot and hurried - a deliciously intense fic!
Supernatural
Come On Now, Bring It On
By: apocalypsos
Info: Sam/Dean, NC-17, 3215 words
Summary: Dean has a slight accident during a hunt. (Succubus powers! \o/)
Notes: Goddamn HOT, this one.
Crystal Blue Persuasion (LJ Mirror)
By: Wrenlet
Info: Sam/Dean, Adult, 895 words
Summary: Fucking wings. And a voice that was, in Dean's opinion, marginally more persuasive than normal but really, it was the wings that irritated him most.
Notes: Such a ridiculously hot read, vivid and immediate.
Devil Driven
By:
sometimesophie / crookedassembly
Info: Sam/Dean, Adult, 6416 words

Notes: One of the first supernatural-forces-made-them-do-it fics I ever read in this fandom, and still one of my absolute favorites.
Fuck or Die (LJ Mirror)
By: casspeach
Info: Sam/Dean, NC-17, 9347 words

By: deirdre_c

The Taste on Your Tongue
By: nomelon
Info: Sam/Dean, NC-17, 3377 words
Summary: I guess you could call this sex pollen fic. Or maybe giant flying slug-monsters made us do it fic. Or just, y'know, porn.
Notes: over-the-top-awesome and HOT.
Top This
By: Leonidaslion
Info: Sam/Dean, NC-17, 4046 words
Summary: Dean's sure he's a top. Only problem is, Sam's pretty sure that's his job.
Notes: One of the hottest things you'll ever read. Seriously. Delicious and off-balance and sexy as hell.
Truer Words Were Never
By: rivers_bend
Info: Sam/Dean, R, ~5,000 words
Summary: to the prompt: something supernatural messes with Dean, making him more honest/open.
Notes: This fic is a marvel of humor, hilarity, sweetness, and Dean being uncontrollably honest and adorable. A favorite, to be sure.
Your mouth was made to suck my kiss
By:
fleshflutter
Info: Sam/Dean (+ sort of Dean/OMC), NC-17, 6828 words
