love these requests! these are pretty much my favorite kinks :)
i've only seen one fic with number 2 in it and i don't think i saved it, but if you have any links to fics under that category that you've already read, i'd love them.

here are some recs for you:
1. Five times Dean made Sam come in his pants. (http://lyra-wing.livejournal.com/60745.html) - hot and funny
That Point (http://cmere.livejournal.com/145397.html) - "Don't start that shit with me again, Sam. It's like you want me to kill you."
Someone Else's Blood (http://sevenfists.livejournal.com/45347.html) - Fanfic cliche #62: Character X and Character Y have to pretend to be dating! (also has semi public sex)
3. Bulletproof (http://smokeringhalos.livejournal.com/12331.html) - Sam has three bulletproof kinks, and Dean has one of his own.
4.The Sunless Land - High-school AU, in which Sam and Dean don't know each other. But, of course, not everything is what it seems.
Summer Blackout (http://nutkin.livejournal.com/10015.html) - When Dean is seventeen, they spend five months being normal.
Fix(ation) Series (http://drvsilla.livejournal.com/tag/fixation) - Preseries, Sam has a oral fixation and likes to suck Dean's thumb.
all i wanna do is make a mess out of you (http://blue-soaring.insanejournal.com/5148.html) - He's got Dean, who's a handful of needs barely met, a lot of wants never asked for, who's push come to shove.
Famous Last Words (http://blue-soaring.insanejournal.com/3558.html#cutid1) - It's rare enough that he wants to tag along on a regular salt and burn that no way was Dean telling him no.
(Not) Right in the Head (http://blue-soaring.insanejournal.com/3024.html#cutid1) - t's the longest fifteen minutes of his life before he finds something worth stopping for. **one of my favorites, scorching hotness
The Second Law of Thermodynamics - Dean used to be a geek, Sam's failing physics, and they both suck at communicating
Paperwhites in bloom (http://estei.livejournal.com/20171.html?style=mine) - Sam gets the point, he just doesn’t listen.
Again (http://plutogirl10.insanejournal.com/2064.html) - I was prompted with "Dean-and-Sammy-with-John-in-the-next-room". This be it.
Another Chapter (http://sinuous-curve.livejournal.com/27498.html) - They’ve been through the routine a hundred times growing up; they come, they stay for a moment, and then they’re gone…but it never really gets easier to deal - This is not a perfect story, but it has some beautiful and true moments that make every imperfection worth it.

i'm in the process of doing some hardcore organization of my fic bookmarks, so these are just sort of off the top of my head. i know i have a lot more, especially for 4 and 5. i'll probably be back to rec some others.

enjoy! (http://lyra-wing.livejournal.com/66128.html) (http://impertinence.livejournal.com/271657.html) ()
