Author's Note: Unabashed smut. I might've accidentally gotten some plot in it along the way.

This was written for the Fallout Kink Meme, for this prompt:

HOW ABOUT SOME FUCKING TOUGH LOVE BETWEEN TWO FUCKING TOUGH MEN BECAUSE THEY'RE THE MOTHER FUCKING TUNNEL SNAKES AND BITCHES CAN TAKE THEIR SHIT ELSEWHERE BECAUSE THESE TWO FUCKING MANLY MEN NEED TO GET THEIR DIRTY FUCKING TUNNEL LOVE ON. IN FACT, BITCHES CAN JUST GET THEM SOME BOOZE AND FUCK THE FUCK OFF BECAUSE NO BODY AND NO THING CAN GET BETWEEN LW AND THE BUTCHMAN. TITS ELSEWHERE THANKS, AND LEAVE THE POMADE.

This pairing/concept grew on me like a tumor and what started as a one-shot turned into a series. It's published here as a single story for simplicity's sake, but please note that this is a series of interconnected vignettes rather than a single story arc.

TL;DR: Think of these as episodes rather than chapters.

Rated M for language and sexual content.

UPDATE:

If you've returned recently, you may notice that this series is marked as complete. I've had a lot of people ask me if/when I'm going to write more of this, and I appreciate that so, so much. I cannot say enough thanks for all the support and readership and comments I've had for this fic series over the years.

Thing is, this fic is over five years old. I am in a very different place as a writer now than I was then-stylistically, skill-wise, subject matter I'm most interested in, and so forth. And while I have loved writing about Butch and Jay, this is a series that's very hard for me to get back into now without looking at that early writing and becoming extremely self-critical of it. It's very hard to think about writing any more for this series, and thus drawing attention back to it, without a lot of rewriting to bring the rest of it to my current standards, which would be no small task. And it's a task I just don't have the heart for anymore. I have other stories, in Fallout and in my other fandom, that I feel a lot more investment in these days.

So as it stands, this series is no longer ongoing. It was always that, a series of interconnected fics, rather than a single story arc, and each is complete in its own right. If the inspiration and desire ever returns to come back and give it a proper update/rewrite, I certainly will. But as of now, this is Tunnel O' Love, the whole of it, for better or worse.

Thank you again for reading and for your support over the years. I truly appreciate it.


"Fuck," Butch spits, shoving Jay against the wall of the empty dining room. Jay says nothing, just bites Butch's neck in a way that's probably going to leave a mark.

This may not have been exactly what Jay had in mind when Butch asked him to join the Tunnel Snakes. Hell, it isn't what Butch had in mind either – well, not in the front of his mind, anyway – but fuck if he's gonna back out now. He had some initiation prank in mind for tonight but it goes clear out of his head as Jay yanks down the zipper of his Tunnel Snakes jacket.

"Who told you you could lay your motherfucking hands on my jacket?" Butch growls.

Jay shoves Butch's hands off his shoulders and yanks the jacket roughly down Butch's arms. The leather hits the floor with a smack. "What now, DeLoria?" Jay smirks.

In all their eighteen years, Jay's been the only one in the vault who doesn't take Butch's shit. Fuck, Butch knows his own bullshit is bullshit, he's not a fucking moron. It's the fact that no one else seems to, that he can leer and elbow his way around this fucking steel rat maze with nothing more than a few dirty looks, even from the goddamn Overseer. Because even he knows what's up. No one says shit to Butch DeLoria.

'Cept for James Junior here, only no one calls him James Junior because he'd punch them in the kidneys if they did that, reminding him whose kid he is, because let's face shit, nobody likes the fucking doctor, with his bitch accent that no one else in the vault has, and his fucking patronizing doctorvoice he uses on everyone like they were his kids, too. Jay has the good sense not to like his dad, even if he still loves him because he's his dad, and well, shit, that's what you do. Like, Butch still loves his mom in spite of everything but that doesn't mean he's gonna let her drunk ass or anyone else push him around.

Jay gets that. Jay's been mouthing off to his dad and everyone else since he could talk. Butch still remembers the first time Jay said 'fuck' to him personally, when they were like ten or some shit. In this room, in fact, like five feet from where they're standing. Go fuck yourself, Butch. I'm not giving you my sweet roll. Jesus, the whole room had gone silent. Butch grins involuntarily at the memory, and grabs Jay by the shoulders again.

Jay's always had a fucking mouth on him, and right now Butch wants that fucking mouth on his cock.

He tries to shove Jay to his knees, but Jay's not going down, the little fucker. Jay spins him, pinning Butch to the wall. "That how it's gonna fucking be, DeLoria?" He's got Butch's jumpsuit unzipped to the crotch and is shoving Butch's white undershirt up, bunching it under Butch's armpits while he bites at his nipples. This kid and his fucking mouth, Butch thinks, groaning as Jay's hand plunges into his underwear.

"Fuck," Butch snaps at the sudden friction as Jay yanks his cock out, all the while giving his nipple a hard suck. He's already throbbing like a mofo, has been from the minute Jay laid his hands on him.

Jay drops to his knees. About goddamn time.

Butch's vision swims for a moment as Jay grabs him in a rough fist and plunges his mouth onto the head of his cock. Teeth graze the sensitive underside and Butch curses again, grabbing fistfuls of Jay's hair, which if anyone did that to Butch they'd piss blood for a week because you don't fucking touch the Butchman's hair, but Jay doesn't do the pomade thing, wears his dirty-blond curls loose and lets them fall into his face and refuses to get a trim just to piss off his old man. It makes him look careless and sloppy and, Butch has to admit, pretty fucking hot. Girls try to touch it, like Wally's bitch sister, and unlike Paul who thinks getting chicks to hit on him is the fucking point of life, Jay just jerks his head away and tells them to fuck off and take their flirtygirl bullshit elsewhere, which is also, Butch thinks, pretty fucking hot.

Tugging Jay's hair, he tries to thrust himself deeper. Jay seizes Butch's hips with both hands and shoves him flat against the wall, holding him there as his rough tongue swirls, and god, those fucking lips. He looks damn good down on Butch's cock, and Butch tries to thrust again, but Jay keeps him locked against the wall, digging the heels of his hands into Butch's hips and pressing his elbows into his thighs. He's gonna have bruises. "Fuck," Butch gasps again as Jay sucks hard, his lips sliding up the shaft until Butch is deep in Jay's throat. He has to hand it to the kid, whatever his workout routine is, because his arms have Butch pinned so tightly to the wall he can't move his hips at all, and he's trying, straining against Jay, wanting to fuck his hot mouth. Instead he fists Jay's hair harder and snarls, "Fuck, Jay, your fucking cocksucking mouth," as Jay's tongue works him and the ache in the pit of his gut twists tighter and pleasure burns along all his nerves.

And Jay pulls off.

"God damn you," Butch gasps in frustration. The fuck is with this guy? But Jay's up again and pulling down the zipper on his own jumpsuit as he shoves his hips up against Butch, who feels a cock as hard as his own jabbing him in the hip. "Shit, this how you want?" Butch hisses, and goes to work pulling Jay's jumpsuit off his arms and down his waist, and shoves his hands under Jay's white t-shirt, pinching a nipple and enjoying the kid's gasp. If Jay wants to get fucked, then goddammit Butch is gonna fuck him, and good.

Jay smirks but pulls Butch's hands off him long enough to get Butch's jumpsuit down and pull his own t-shirt over his head. "Who the fuck came up with these things?" Butch mutters. Would it have been so much fucking trouble to issue vault uniforms that came in two pieces, so Butch wouldn't have to worry about tripping over his own sleeves as he shoves Jay toward the closest red booth? "This how you want it, huh?" He yanks Jay's suit down further, and his underwear with it. Jay lets himself be pushed around so Butch can grind against that tight ass, panting with anticipation. Butch has the decency to spit into his hand before reaching around to give Jay's cock a few strokes. He's not a total asshole. Jay sags against him, groaning.

Then he grabs Butch by the arm and hauls him around in front of him, and before Butch knows what's happening he's on his back on the red bench and Jay's crawling on top of him with that fucking smirk on his cocksucking lips. "You bitch," Butch spits, and Jay drops that mouth to Butch's cock again and drags his tongue up the shaft, the sensation smothering any further protests that might have risen in Butch's throat. A few more long drags and Jay stops, kicks off his boots and wriggles the rest of the way out of his jumpsuit, straddles Butch with one foot on the floor and one knee jammed between Butch and the back of the seat, and slides down on him so smooth Butch wonders fleetingly if Jay's done this before and with who, because Butch has actually never done this, and. . .god damn. Butch's eyes roll back and he groans at the hot tightness gripping him. "Fuck, Jay. Fuck." He pushes upward, and this time, Jay lets him push. He's sweaty and gonna stick to the damn seat, but who could give a fuck, with his dick deep in Jay's ass like this. Jay rolls his hips, grinding on Butch, and then grabs Butch's t-shirt to drag it over his head and toss it aside.

Butch and Jay have been beating the shit out of each other their entire lives and Butch knows his rival's tight, compact body pretty damn well by now but it's still fucking awesome feeling the squeeze of Jay's taut thighs around his hips, watching Jay's muscular chest heave with his motions and heavy breaths, his broad hand pushing back the curls falling in his face. He'll look good in the leather jacket but Butch knows he hardly needs it; Jay could walk around balls-ass naked all the time and still no one would fuck with him. Jay would look like a badass if you painted his nails and put ribbons in his hair. He's a natural.

He leans down to bite at Butch's neck and shoulders, grinding so fucking slow it's agonizing, until Butch gasps, "God damn you, Jay," and grabs his ass to make him move faster, harder.

Jay laughs and straightens, pushing himself up and slamming back down so fast Butch's vision goes fuzzy at the edges. The tension in his body spirals tighter as Jay rides him hard, harder, so fucking hot and tight, sliding faster and faster on him until Butch comes with a strangled cry, his whole body shuddering under Jay. Jay smacks his hip, hard. "Who's the bitch now?" he gasps out as he comes in hot spurts across Butch's bare chest. "You son of a bitch," Butch mutters, breathing heavily, but he doesn't mind, not really; it's pretty hot, actually.

Jay laughs again and slides off, and the intense drag makes Butch shudder again. He climbs off Butch and starts to grab his clothes, using his own t-shirt to wipe off Butch's chest as Butch peels his back off the vinyl-covered bench and sits up.

They get back into their clothes. Jay collects Butch's jacket and throws it at him. Butch catches it and tosses it back. "Take it. You're in." He's got a spare in his room his was planning to give to Jay, but he kind of likes the idea of Jay wearing his jacket, even if no one else knows it.

Jay smirks, triumphant, and shrugs the jacket on like he was born to wear it. Fucker.

Footsteps in the hallway. It's Crazy Beatrice in the doorway, squinting in the darkness, probably up for a midnight snack or some shit. She opens her crazy mouth to say something, probably something stupid like What are you boys doing up so late? like it isn't fucking obvious. Jay doesn't have his boots back on yet and his sticky t-shirt is still lying bunched on a table, and even Butch's hair is a little rumpled from being on his back in the booth.

"The fuck you looking at?" Butch snaps. "The motherfucking Tunnel Snakes, that's what. Fuck off."
