Bright light seeping through his eyelids has sleep abruptly leaving Buck. He squeezes his eyes tight with a disgruntled sound before blinking them open to find the lamp on his nightstand glaring back at him. A lamp he is like ninety-nine percent sure he turned off before falling asleep. He squints passed the light, passed his arms curled up next to his face, to see nothing but darkness behind the window across the room. A pleased smile quirks his lips at the prospect of getting to sleep for hours more. Buck shrugs off the lamp mystery and reaches out to turn it off-
Only to jerk to a stop inches later. The forced stop jars through him. Blinking with confusion, he finally looks at his hands to find thick leather cuffs cinched tight around his wrists, shiny silver locks shut around their buckles. A jolt of panic has him fully awake as he traces the gleaming silver to thick chains that stretch over his head. He attempts to yank his arms down only to be met with the loud clang of said chains against the bars of his head board. Buck’s head snaps back to look. It’s one chain, attached at both wrists, looped through two of the thick iron bars, leaving him about a foot of slack on each arm. The sight has him regretting his IKEA decisions right about now.
“Bout time there, sleeping beauty.”
The voice has Buck’s heart leaping as he jerks over onto his back, arms forced to be raised over his head by the restraints. He blinks at the shadowed figure leaning against the wall across from the foot of his bed.
“What the hell?” He pants, breath picking up with his heart rate.
“Mmm,” the figure hums and slowly moves into the light.
Buck’s heart stutters, his face dropping into a confused frown when a familiar face is revealed.
“Eddie?”
A sharp grin stretches across his best friend’s face.
“Not exactly.”
The warm brown of Eddie’s eyes is suddenly swallowed by pure black from corner to corner- no color, no white, all terror. Buck scrambles back, bare feet tangling in his comforter as he cowers as close to the headboard as he can get.
“What the fuck?” he breaths.
In a blink, Eddie's eyes are back to normal and the thing that’s controlling him is shrugging his shoulders.
“Eddie’s taking a break right now.”
“What the hell does that even mean?!”
Buck’s not stupid but the reality of Eddie being possessed by a demon is a little difficult to wrap his head around.
“Well you see,” Eddie’s body rips the blanket out of where it’s tangled in Buck’s legs, making him jerk back. “Eddie here got drunk and read a very bad thing on the internet about letting go of inhibitions and repression, so here I am to help him go after what he wants.”
“Well I can tell you he definitely doesn't want you controlling his body!” Buck barks.
Not-Eddie laughs, then shrugs his jacket off.
“Too late for that. Eddie read the script- out loud, the idiot. Which means he agreed to let me take the reins until his craving is satisfied, whether he knew that at the time or not.”
Eddie’s boots are kicked aside and Buck becomes acutely aware of the fact that he’s nearly naked, half laying against his bed frame in nothing but a pair of grey boxer briefs. Apprehension trickles down his spine.
“Wha-what craving?”
Not-Eddie smirks. In a move that happens far faster than it should, he lunges forward, clamps his hands around Buck’s ankles, and yanks. Buck yelps as he’s laid out flat on the bed, arms stretched over his head, feet nearly dangling off the end. He shakes off the moment of surprise and kicks out with both legs, dislodging Not-Eddie’s hold almost violently.
“Ah ah.” Not-Eddie tisks with hands held up. “I might be in the driver's seat but this is still Eddie’s meat suit. He’s left with the consequences of anything that happens to it. You just remember that if you want to fight back.”
Buck stills.
Shit.
Not-Eddie pulls off his shirt and Buck stiffens from head to toe.
“What are you doing?” he demands.
A brown eyebrow is raised.
“Come on, Buck. You’re not that slow are you?”
Buck tries to fight the tingling tremor that radiates through him at the low tone. Not-Eddie leans in and grabs the fabric of Buck’s briefs, long fingers wrinkling the garment on the outsides of Buck’s legs. His muscles stiffen and he has to bite his tongue to keep from kicking out at his best friend’s face. Not-Eddie yanks and in one smooth move, Buck is bare and naked. Buck’s head shakes back and forth uncontrollably while Not-Eddie stares, eyes dragging up and down Buck’s body with a hungry glint. Buck’s eyes snap wide when Not-Eddie starts undoing his belt- he doesn’t remove it from his jeans, just unbuttons, unzips and pushes it all down. The growing tent in the black briefs beneath has Buck pulling his knees up to cover himself.
“No. No nonono. That’s not-” Buck pants, chest heaving in fear.
“Oh but it is, Buck.” Not-Eddie cuts him off in a condescending lilt.
His legs are yanked out straight again but Not-Eddie doesn’t stop there. Strong legs swing out to straddle Buck at the hips and it takes everything in him not to fight this… thing tooth and nail to get it the fuck off of him. He wants- needs- this to stop but the thought of hurting Eddie makes him even more nauseous than this thing taking control of him. His head is still shaking in denial as Not-Eddie skates his hands across Buck’s chest, sending shivers of what Buck really wishes was disgust along his skin.
Not-Eddie brushes a finger across one of Buck’s nipples, erupting goose bumps. He definitely notices and keeps doing it, one finger brushing softly back and forth until Buck’s nipple is stiff and he has to grit his teeth against the sensation. Not-Eddie leans forward, nudges Buck’s head back to expose his neck and starts nosing at the sensitive flesh. Buck pries his jaw open to protest when Eddie’s lips start pressing teasing kisses to the stiff cord of his neck.
“No. No, Eddie’s straight.” Buck’s rasps, voice quivering.
Not-Eddie hums into Bucks’ throat, kisses getting firmer and sloppy- tongue darting out to leave hot stripes of saliva on Buck’s skin.
“Not sure how straight it is to fantasize about fucking into your male best friend’s ass until your cum leaks out of him.” The demon muses.
A breath is punched out of Buck’s lungs, eyes glued to the ceiling to try to ignore the twitching from his cock at the revelation.
“Not to mention the whole white picket fence, growing old together crap. But that’s not my area of expertise.”
Not-Eddie latches his mouth onto the thin skin beneath Buck's jaw and sucks, harsh and fast, teeth firmly gnawing at the area to make it ache and bloom purple. Buck squeezes his eyes shut and shakes his head as much as he can with Eddie’s mouth attached to him.
“You’re lying.” Buck growls.
Not-Eddie breaks away with a laugh. He settles his hips back so his ass is pressed into Buck's mostly soft cock. Buck's muscles go rigid when Not-Eddie starts rocking in his lap, purposefully working him to hardness with incessant friction. His eyes are dark where he towers over Buck- those carmel brown eyes that Buck adores hot with lust.
It's not like Buck hasn't had his own fantasies about this. Eddie taking what he wants from Buck, using him, touching him, loving him. But this is not Eddie. This can't be what Eddie wants.
The demon licks his lips with a wicked smile, seeming to relish in Buck's fear.
“I'm in his head, Buck. I've seen all of it. Every thought he's buried deep deep down? That's what I feed on. Bringing that to the surface, making it happen however I see fit?”
Eddie's body shivers in ecstasy.
It makes Buck's stomach heave.
Not-Eddie breathes a laugh.
“That's my job. The deal that idiots like your boy make.”
“Just let him go.” Buck begs quietly.
Not-Eddie lowers back over him so their faces are a breath away.
“Not until I'm done with you.”
The statement is still echoing in Buck's head when he's flipped over onto his stomach. The soft impact makes him grunt- the sound nearly drowned out by the clatter of the chain crisscrossing with his new position. Buck blinks into his pillow in confusion, his breaths bouncing back at him heavy and humid. Not-Eddie is somehow still straddling him, his hard dick pressed against Buck's ass like a brand. His body drapes over Buck until his lips brush Buck's ear.
“I've seen how you look at him, pretty boy. He doesn't know what the fuck me eyes mean but I do.”
The lips sear a blazing path as the demon works his way down Buck's body- teasing and light. Just enough to make Buck cock perk up and fill slowly against the mattress. No matter how much he internally screams at it to stop.
“He doesn't realize you've been begging for this for years.”
He pauses at the base of Buck's spine.
“Though he didn't realize he wanted this until a couple months ago so maybe you're both just that stupid.”
The sentence is punctuated by callous hands roughly spreading Buck's ass cheeks.
Buck squeezes his eyes closed, forcing the brewing tears to trickle down his face and hopes for this to be over quickly.
“Fuck, look at that pretty little hole.” Not-Eddie groans in appreciation.
Buck jerks when a thumb brushes over him.
“Would you just get this over with?” He snaps brokenly.
“Not a chance, beautiful. Eddie wants you to enjoy it. Hell, I want to enjoy it. I'm not just gonna shove it in.”
That thumb circles around the tight furl of his hole, teases with pressure on every second round, but doesn't come close to entering him. Buck's not sure if he's grateful that the prospect of bodily injury is off the table if it means this is getting drawn out.
“In all his fantasies you're nothing but a whimpering mess.” A dark chuckle. “When he makes himself come, it's to the thought of you begging for it.”
Buck can't quite choke back the whine before it breaks free of his throat.
A pleased laugh from the demon.
“Yeah, just like that.”
The teasing thumb leaves- Buck doesn't have time to feel relief before it's replaced with a slick finger pressing into him. Buck tenses and grunts at the sparks of pain the intrusion brings. Not-Eddie slides a hand into Buck's hair. It rakes through his curls too gently, his thumb rubbing a soothing pattern behind Buck's ear.
“Hey, no. You're okay. Just relax, Buck.”
He's softened his voice, used that fond undercurrent Eddie uses to calm Buck down and Buck doesn't want to but his muscles automatically sag at the familiar confort. He chokes on a moan when that finger subsequently sinks in with no more resistance.
“That's a good boy.” The demon's mean lilt is back.
He twists his finger around, testing the give of Buck's hole before starting to fuck him with it slowly. Buck groans in frustration as his body betrays him- cock hard and leaking into his sheets, hole greedily clutching at Eddie's- fuck- two thick fingers. It feels wrong that there's no discomfort, no more pain, just heat and pressure that's making his head hazy. Making it harder to swallow down all the sounds his body wants to spew. Those fingers scissor and pull, stretching Buck open, drawing prickling cold sweat to his brow. And the demon starts talking again.
“I almost didn’t wake you up,” he muses, “You’re an awfully deep sleeper, Buck. Could have just locked you up, spread you open and slipped right in.”
Buck yelps as thick fingers find his prostate and start massaging over it with each inward push. Not-Eddie lets out a pleased hum at the shakes building in Buck’s thighs.
“Would have left you like that. Full of your buddy’s cum and no clue how it got there.”
A third finger presses in- Buck chokes on a whimper.
“You’d love that wouldn’t you, Buck? You’d live the rest of your life filled with Eddie’s cum and be the happiest little puppy about it, wouldn’t you?”
The taunt, along with the orgasm forcibly building in his gut panics Buck enough to try to buck the demon off with a growl.
“Fuck you.”
Not-Eddie doesn’t budge, just shoves Buck’s hips down with his free hand, his other targeting Buck’s prostate pointedly.
“I’m getting there.” The demon purrs.
Buck’s breathing has escalated to burning gasps by the time Not-Eddie pulls his fingers free, his teeth nearly piercing through his lip against a needy whine. A grunt is then punched out of him at the blunt heat presses into him. He’s filled in one searing thrust.
“Guh-”
Buck can’t fight the breathless, broken groans that fall out with each breath. His hands scramble for purchase against the headboard in search of something to ground him against the overwhelming sensation of being so fucking full that over takes him. It’s all so hot and wet- the access lube that he can’t remember the demon adding to the situation dripping down around his balls, the tickling trail rising goosebumps. The knowledge that he’s full of Eddie’s cock makes it all the more intense. The first thrust that follows has Buck smothering a high pitched moan into his pillow.
“Fuck,” Not-Eddie groans in satisfaction, “Nice and tight. Good to know that useless ex-boyfriend of yours didn’t stretch you out before Eddie could.”
The snarky comeback on Buck’s tongue drips out as nothing but drool into his pillowcase, pushed out by the next thrust that leads into a steady, intoxicating rhythm. It takes far too few strokes for the heat of impending orgasm to threaten in his gut. Buck’s eyes snap open and he stiffens his legs- his everything- to fight it.
“No-” he chokes as his hole flutters around Not-Eddie’s smooth ministrations.
Unfortunately, the demon notices.
“Aw,” he mocks, “you gonna come already?”
Buck shakes his head vehemently even as his dick throbs in the contrary.
“Good. I’m not done with you.”
The threat is snarled into Buck’s ear before he’s abruptly ripped from the edge of orgasm and twisted onto his back hard enough to knock the wind from him. His hole is left cold and empty for all of heartbeat before Not-Eddie roughly shoves Buck’s thighs apart and slams back in. Stars are dancing behind his squeezed eyelids in threat of unconsciousness by the time he’s able to suck oxygen back into his taxed lungs. The first exhale ends with a guttural moan when Eddie’s cock punches into his prostate dead on. He manages to deescalate the sounds to bitten off whimpers at the electric pleasure ripping through him with each mean thrust. Luckily, the lack of constant pressure against his cock keeps the threat of orgasm at bay.
Not-Eddie settles his weight down, pressing their chests together, their combined sweat making a slick drag between them. Hot breath rushes over Buck’s scrunched up face.
“Aw, c’mon Buck. Show me those pretty blues. Eddie wants to see them.”
He hadn’t realized his eyes were squeezed shut until the demon’s taunt. Buck lets out an argumentative grunt through clenched teeth, refusing to give into his request even as the weight of his gaze burns into his face. A moment later, Eddie’s body jerks and chokes on a gasp that makes Buck frown.
“Buck.”
Eddie’s voice-his real voice- has Buck’s eyes snapping open and ignoring the shadows caused by the abrupt lighting change. His best friend’s face is pinched in a mix of agony and pleasure, his hips still pistoning into Buck. Their gazes clashing makes the filthy sounds filling the room fade away. Buck focuses on the clear brown eyes in front of him, the lingering sense of other temporarily absent.
“Eddie?” Buck whispers.
“I’m sorry- fuck- I’m so sorry, Buck.” His voice is broken by involuntary moans. “I ca-I can’t make him stop.”
He stops with a choked off sob as his eyes well with tears.
Buck feels his own eyes match.
“Hey, shh. Eddie-ah- it-it’s okay.”
“I love you. I’m so fucking sorry.”
They both devolve into moans as tears drip down their faces.
“Fuck. Eddie. I love- I love you too.”
Eddie surges forward and presses their mouths together- teeth clacking, tongues tangling, the taste of him mingling with the salty tang of their desperate tears.
It’s cut off too soon when Eddie rears back with another gasp, hips stuttering through a thrust with closed eyes before they flutter back open with a grin. The return of solid black makes Buck’s gut sink- as much as it can while the demon hammers into him.
“Alright, that’s enough of the warm fuzzies.”
Not-Eddie clamps his hands on Buck’s thighs, the tight grip pushing them farther apart. He loses track of time after that- minutes, maybe hours pass as the demon picks up his thrusts. The room heats, swamped with the combined sounds of their skin meeting with force, the slap and obscene squelch of lube harmonizing with Buck’s broken moans and whimpers, Not-Eddie’s deep grunts and groans. Buck keeps his eyes pinched shut, the memory of Eddie saying he loves him playing on repeat behind his eyelids to hold him through until this nightmare is over.
A hand wrapping around his cock in a nearly too tight grip has him jerking back into the moment with a surprised cry. The demon laughs through a moan and starts stroking, his grip smoothed by the river of precome that has been flowing from his slit.
“No-fuck-” Buck chokes against the overwhelming surge of sensation.
Not-Eddie grins at him, pace not slowing.
The orgasm flares like a wildfire- once contained behind a mental wall with the lack of stimulation to his cock- now raging to the forefront and refusing to be choked back.
“That’s right, pretty boy,” the demon taunts, “come for me.”
Buck shakes his head desperately against the words even as his hole clamps down before the dam bursts and his cock spills all over Not-Eddie’s hand, ropes of cum reaching to Buck’s chin as he curls in on himself as much as he can with the restraints. Choked moans are ripped from his chest as he drowns in waves of shameful pleasure that feel neverending.
“That’s it, give it to me.” Not-Eddie growls as he works him through it.
Sparks of pain start to lick up his cock from overstimulation when his orgasm slowly fades, making him squirm and whine against the hand wrapped around him. The demon gives a firm squeeze to his softening dick before releasing him. Buck sobs in relief even as his prostate continues to be battered. Not-Eddie then plants both hands on either side of Buck’s head and lowers his face until their noses brush, forcing Buck to stare into his sweat slick face. Buck is too wrung out to even flinch back.
“My turn.”
The demon’s voice has gone breathless, hips stuttering. It only takes a few more hard thrusts before his eyes flutter shut, hips grinding deep, and a near roaring groan fills the room. The warmth spreading through him as he’s filled with his best friend’s cum forces a weak moan from Buck’s lips. Not-Eddie’s heaving breaths wash over his face, little twitches of his hips forcing his cum deeper. He lets out a pleased hum when they finally still. The room lays quiet except for their labored breathing for only a moment before the demon places a quick kiss to Buck’s forehead that makes him grimace, then settles back on his knees- cock still nestled inside Buck.
“You done now?” Buck grumbles.
“Hmm, almost.”
Not-Eddie leans over and grabs something from the other bed side table then returns to Buck- who can’t quite make his eyes focus on the dark blob in the demon’s hand. Not-Eddie leans back, hand and object disappearing between the two of them. There’s a brief period of cold and emptiness as he shifts back and his softened cock slips free- and then Buck’s confusion is quickly dispelled with a gasp. His hole is swiftly filled again, what was clearly a plug now nestled snuggly inside of him. Not-Eddie’s face brightens with glee as he flicks the flaried base of the plug making Buck jolt from the vibration against his prostate.
“There,” the demon sighs, “nice and full.”
Buck’s limp body stiffens yet again when the demon lays Eddie’s body across Buck. Another kiss is smacked to his cheek before he pulls back and winks at Buck.
“Thanks for the good time, pretty boy. Have fun with your happily ever after or whatever.”
Eddie’s body goes limp, eyes rolling back into his skull before Buck can respond. A gruff ‘oof’ is pushed out of him at the impact of his best friend’s body pinning him to the bed. The fear awakened by stillness from Eddie’s body overshadows the lewd slide of their skin from the mess of cum on Buck’s chest.
“Eddie?” Buck pants.
Eddie jerks once and then his chest expands on a long gasp. Buck sighs in relief as Eddie scrambles up onto his hands and knees to hover over Buck. The panic flittering in his brown eyes is soothing to witness, proves to Buck that his Eddie is back.
“Buck, I-”
Buck cuts off the breathless rush with a soft question.
“Did you mean it?”
Buck’s teary eyes flick between Eddie’s, watching as his brows pull down in confusion.
“Mean what?”
Buck swallows thickly but forces the words out.
“That you love me.”
The answer will either fix this entire night or break Buck to his core.
Eddie’s eye soften. He shifts and brings a hand to Buck’s face. His thumb brushing reverently against Buck’s birthmark has his breath stuttering.
“‘Course I meant it.”
Buck’s tears spill over in relief.
“Yeah?”
“Yeah. I love you, Buck. I’m sorry it took all of this for me to say it.”
Buck shrugs, a small smile ticking up his lips.
“Could have been worse.”
Eddie chokes out a laugh through his own tears. He keeps his hold on Buck’s face when he kisses him softly, love and devotion poured between their lips. Buck pulls back before either of them can deepen it.
“Any chance he told you where the key is?” He shakes his hands so the chains jingle pointedly. “Arms are kinda going numb.”
Eddie laughs and pulls away- Buck whines in protest.
“Key’s in my pants pocket, baby.”
Buck huffs but allows him to climb off the bed and retrieve it without further protest. Eddie makes quick work of unlocking the restraints. Finally free, Buck rubs at the reddened skin.
“Here, let me get that too.”
“Get what-”
Eddie’s fingers brushing against the base of the plug have him slamming his legs closed- as much as he can with his best friend kneeling between them anyway. Eddie raises a brow at him. Buck mimics the action.
“Nuh uh.”
Eddie’s gaze darkens with lust.
“No?” He asks, voice low.
Buck's shrugs. Smirks.
“Heard you had a thing for filling me up.”
“You don't seem to be complaining.”
Buck's smirk widens into a grin.
“Nope.”
"You're welcome."
The disembodied voice echoes through the room, the snarky comment making them both jump and look around with wild eyes. Buck jerks his gaze back towards Eddie and points an accusing finger at him.
“You are banned from the internet.”
“Yep.”
