This pairing has recently become my new obsession and I'm constantly on the lookout for good Samifer fics close to your description. Unfortunately it is not so easy so if you have any recs I would be grateful, too!

My favorite ones so far:

Fear of Falling by Hallucifer
https://www.fanfiction.net/s/9936627/1/Fear-of-Falling (https://www.fanfiction.net/s/9936627/1/Fear-of-Falling)

Summary:
Cage!fic. In possibly the worst place in creation, with only a bitter and angry Michael still wearing Adam for company, Sam decides sticking with Lucifer is better than nothing. But with memories of what he learnt about Lucifer while his vessel in mind, Sam finds that maybe the devil's companionship is not as bad as it seems. Eventual Samifer.


I cannot even begin to tell you how awesome and touching this story is. I was actually somewhat depressed and fell in bit of a reading slump when I finished because it seemed like no other fic would ever compare and hit me like that.


Loved You First by Hallucifer
https://www.fanfiction.net/s/9697222/1/Loved-You-First (https://www.fanfiction.net/s/9697222/1/Loved-You-First)

Summary: Lucifer wanted so much for Sam to understand. If he'd just been able to explain, to give his side of the argument. If he could have just let Sam know how much he truly cared for him. Lucifer addresses his thoughts to Sam on everything he truly wanted to say.


Every Heartbeat by suchanadorer
http://archiveofourown.org/works/625133 (http://archiveofourown.org/works/625133)

Summary: From his cage, Lucifer can only see glimpses of Sam's life.


Learn to Fly by devilsduplicity
http://pickthelock.livejournal.com/6304.html (http://pickthelock.livejournal.com/6304.html)

Summary: Lucifer holds Sam hostage at a strange hotel. It's not as bad as Sam thinks.


And I'm sure you have already read

I have combined the PDF's with art into one single PDF file for myself if you would like to have it.


Lastly, I would like to rec a very fun, lighthearted cagefic that is not Samifer but simply Sam, Lucifer, Michael, Adam making the most out of their time together and actually enjoying themselves (not like that, it's gen ;-) )

Sam's Hell by Ella M. Nite
https://www.fanfiction.net/s/6629158/1/Sam-s-Hell (https://www.fanfiction.net/s/6629158/1/Sam-s-Hell)

Summary: For a hundred-and-eighty years Sam's soul has been down in the cage with Lucifer, Michael and Adam. Thank goodness for the rules ... otherwise Sam thinks he might have been in agony the entire time.


I hope you enjoy and have found a few fics you haven't read yet!

Hey, wow, thanks for the fics! Honestly, I wasn't even expecting a reply because I know that not many people read samifer, so thanks!
I just finished reading the first fic (yes, I have read the Fourth Wall series ^^) and you're right, it's really good (I'm totally going to go with the headcanon that Sam jumped in the last chapter D:).
Unfortunately, like you said, there arent many fics under this genre, so I can't really rec anything much for you...I'm pretty sure the ones that I have, you've already read.

Since you said that Fear of Falling was your favourite samifer fic, I would like to share mine.. I'm sure you've already read it, because it was quite popular with the Samifer fans on fanfiction.net... Stairway To Heaven (https://www.fanfiction.net/s/9065863/1/Stairway-to-Heaven) by SnarkyMuch2
Summary: AU. To save his brother, Sam makes a deal with the devil. The creature he expects and the man he actually encounters are two different beings, and soon he will have to choose between what he knows is right and what his heart desires.

If you haven't read it....Seriously, I can't begin to tell you how much I loved this fic. To date, it still remains my favourite ever Samifer fic, and I still go back and read it, because I love it so much. Like you, I was kind of depressed after finishing it because I thought I'd never be able to find another fic to compare. And I haven't so far (it's actually really depressing because the author promised us a sequel and she suddenly disappeared and hasn't come back).
Anyway..word of warning when you read it..carry a box of tissues, because you're going to need it! D:

So apart from that, like I said, I really don't have any good samifer fics in that genre. I do have two short fics, by Fightlikeagirl (actually I'd recommend all of her/his fics), but they're more to do with possessive!lucifer (who's a little bit obsessed with Sam), than a Lucifer who's actually in love with Sam.

Nothing You Do at Gunpoint (http://archiveofourown.org/works/557567?view_adult=true)
Summary: If he had any sense, he would have called the police weeks ago.

You Are The Bullet In The Chamber Of The Gun (http://archiveofourown.org/works/642189)
Summary: "You're not the Devil," Sam says, trying to sound more confident than he feels. He loathes these calls, but he's the only one Lucifer will speak to. "You're a sick, deluded murderer, Luke, you're not the Devil."

I'm pretty sure you would hav read this, but still, won't hurt :P

Break, Fill, Overfill (http://libraryofsol.livejournal.com/135453.html) by Libraryofsol is good.
Summary: Sometimes it's not about what you can see.

Apart from that, there is this other fic...but the possesiveness protectiveness that Lucifer has towards Sam is only briefly touched on and it's an eventual Sastiel fic, so I don't know how much it'll interest you. It's still a realy good read though so I'll share it with you

The Art Of Tying Bonds With Scissors (http://archiveofourown.org/works/1059499/chapters/2123227) by lysanatt
Summary: When Sam unexpectedly bonds with Lucifer, a high-ranking traditionalist alpha, Sam's beliefs about free will are put to the test. But bond or no bond: there is no way Sam will let biology get the better of him. When Castiel, Lucifer's younger brother, makes an offer that Sam literally cannot resist, Sam knows it's his chance to be free of Lucifer for good. Still, living with one mate while being unhappily tied to another is like tying bonds with scissors: it's doable, but it certainly isn't easy.

Yeah...
Anyway..again, I really appreciate the recs you gave me! Even though I wasn't much help, I hope you enjoy the fics I recced for you (if you haven't already read them)

I'm glad you liked Fear of Falling and found a few recs you have not read it yet.

And thanks so much for the recs you gave me, most I don't know yet. I'm rather new to this pairing and am always thrilled when I find another Samifer fic that fits. You would think there would be more out there... Sadly, most stories I find seem to be only one-shots. They are great, too but sometimes you just want dive into a long story and don't reemerge for a while.

Here is another one, a really long AU that I have heard is really good but I have not started it yet and so I don't know if it fits your criteria:

We Found Love (In A Hopeless Place) by TalesFromPerdition

Summary:

Dean and Sam Winchester struggle to survive when their alcoholic father abandons them. Castiel Novak has turned to drugs in his own father's absence. As their lives spiral out of control, can their new friendship save them, or will it be a catalyst for destruction?

http://archiveofourown.org/works/415182/chapters/689746 (http://archiveofourown.org/works/415182/chapters/689746)

Thanks for the mention of Scissors <3. You might have seen these, then, but both feature a possessive and needy/loving Lucifer, and a Sam who is not (at least at first) interested:

A Young Writer Marked for Death (http://archiveofourown.org/works/2439464) (58K)
Summary: Being an aspiring writer in Paris isn't easy, and with Adam wasting away from consumption, Sam's life sure is difficult. It could be worse, though: Adam could be dead or they could both be back in Kansas where they would end up in jail. Monsieur Lucifer could have asked them to leave Le Cabaret Perdu when he discovered the less than flattering poem that Adam wrote about him. Instead Sam makes a surprising deal with Lucifer that is going to change Adam's life — and his own.

The Temptation of Sam Winchester (http://archiveofourown.org/works/606821) (30K)
Summary: Sam is doing time in Hell, Detroit's new, experimental prison. Caught in the battle between rivaling gangs, Sam finds out exactly how brutal prison life can be. To survive, Sam must make the choice between two gang leaders, the cruel Crowley and the ruthless Lucifer. Lucifer, however, is the master of alluring offers, and soon Sam finds himself falling into temptation.

So I was going through my old posts on this site, and I came across this reply back to this post, and even though I'm a year late (my lj isn't linked to the email account I normally use, so I don't get notifications, so I'm sorry about that ^^), I just wanted to say that yes, I have actually read both your fics and I absolutely loved them, so thanks so much for writing them, because you are one of my favourite writers ^_^
