I pretty much want to rec every Blindfold claim that exists, ever. But! Here are just a few, more will come (haha!) later. Please note the warnings on the fics themselves. (Also, I think a few non-Blindfolds snuck in there too. *handwave*)
Carpal Knowledge by obstinatrix -- (Jared/Jensen, NC-17) -- One of the boys has a wrist!kink that they indulge with the other...oh yes! YUM.
Fundraisers by dragonspell -- (Jared/Jensen, NC-17, 4,420 words) -- Ever since the school went pay-to-play to try and shore up its lackluster budget, the student body has been forced to resort to rather drastic measures: fundraisers. And Jensen Ackles is walking around in a cheerleading skirt and there's no way that Jared can resist that -- despite the fact that Jensen supposedly hates him.
In It for Love by dragonspell -- (Jared/Jensen, NC-17, 136,690 words) -- After a drunken dare, award-winning writer Jensen agreed to on a reality television show to vie for the attention of megastar Jared Padalecki who he's had a crush on for years. Only Jensen doesn't know how he's going to be able to tolerate all the other contestants and their widely varying personalities and he's pretty sure that you're not supposed to be able to get used to somebody filming you 24/7.
No Substitution by rhythmsextion --(Jared/Jensen, NC-17, 5,300 words) -- Jensen's an Omega who's never once felt the desire to bend over for an Alpha. Until he meets Jared.
Not by tryfanstone -- (Jared/Jensen, NC-17) -- Gorgeous take on the alpha canine-ish male/beta male idea running through fandom right now. Interesting insight on social "norms", super sexiness, and beautiful writing. This fic is unique and, even if this isn't your thing, you should give it a read.
Open Your Eyes by fromcainwthlove -- (Jared/Jensen, NC-17) -- mirror!sex, dirty talk/praise, um... manhandling? Also, super sexiness, clear connection and extreme NNNGGHHHH-ness. (Is too a word!)
privacy of storm by mistyzeo -- (Jared/Jensen, R, 2,600 words) -- Snow, boys, gorgeous descriptions, some schmoop. *grin*
September by dragonspell -- (Jared/Jensen, NC-17, 6,170 words) -- Fall was Jensen’s least favorite time of year. Fall meant the Heat and that meant that Jensen had to avoid civilization for an entire month.
