Sugar Rush

Summary:

Isagi sweetens up Rin's sour mouth. 🍭

(For Blue Lock Halloweek 2024: Sugar Rush!)

Notes:

I’m sure this has been done plenty of times by now, but here’s one more version of Halloween Licky Rin! 🍭

(See the end of the work for more notes.)

Work Text:

Listen… Disregard any facts / reality about Champions League scheduling—just like we do with the Neo Egoist League 😂 Alcohol is involved, but both parties aren’t anywhere close to trashed and are more than willing. There’s one or two pretty minor things (in my opinion, which is relative) I’ll warn for in the end notes, so scrollllll down if you have any triggers or squicks.

This fic does revolve around an...aspect...of Rin that is revealed in the U20 arc, so kinda spoiler for anime-only. Y'all gotta read the U20. (Those poor animators...)

Brought to you by: that scene where Isagi hands Rin a drink being animated, that one ridiculous quote from ch 145, Rin’s fuckass striped turtleneck, sleep deprivation, Charli and Billie’s “Guess” remix basically on repeat (until RinSagi go outside, then it’s Gaga’s “Disease”), inhaling Trader Joe’s Cats and Bats sour gummies, rushing to post something for the event I host. 🥴

You’ll need this for reference if the following quote doesn’t prompt an immediate and visceral reaction: “THE WICKED WITCH OF THE EAST, BRO!!”

The usual list of defined idioms / sayings / things I think might not translate well for readers who might be using translator apps is here. The love for bllk is so global, and I appreciate y’all. 💕

Sugar Rush

🍭

 

“I found you, Waldo. Do I get a prize?”

Rin rolled his eyes, though with far less rancor than he could’ve mustered a few years ago.

Isagi didn’t try to keep the smile from widening on his face. “From behind, I thought you were an off-colored mime. Ya know, with all the stripes.” Rin was already trying to glare a hole through Isagi’s face, but Isagi wasn’t done. “Then I saw the beret was actually a beanie, and it got me wondering. The glasses and lack of face paint really are your saving graces. That shirt might make your eyes pop, but it doesn’t really scream ‘Waldo,’ does it?”

Rin celebrated the conclusion of Isagi’s diatribe with a raised middle finger before recrossing his arms, biceps fit to burst through alternating aqua and white.

Rin really did seem to get prettier every time Isagi saw him.

And it’d been too long since they’d last spent any time together. Socially, at least. Outside of a cutthroat atmosphere.

Once the Blue Lock Survivors group chat had revealed that a majority of them would miraculously be in Japan at the same time and so close to Halloween, Reo’d sent a summons. With the threat of ‘no costume, no entry.’

Reo’s penthouse could’ve held hundreds, yet the party was a relatively intimate affair. Once Isagi’d handed over his coat and rounded the corner, the vast open layout had given Isagi a clear view of the guests: mostly Blue Lock or Neo-Egoist alumni and mutual friends made in the National Team, a number of plus-ones, several foreign Champions League players. Good company, the kind of company who knew how to keep their mouths shut and phones off—had Reo’s staff not confiscated them at the door.

The place was beautiful, of course: all clean lines and sparkling glass, Reo’s custom lighting set dim and phasing through eerie colors, understated decorative classics scattered about, conservative but effective use of fog machines. The space was wide enough to accommodate sections, for a playlist of popular songs remixed with a sinister edge to be diffuse enough for conversations to flow. There were a variety of games for drinking, karaoke for drunken singing, and an open bar. Even confectionary delicacies made before guests’ eyes: cotton candy freshly spun, caramel and candy apples freshly dipped. Expensive and festive yet somehow still a little casual, clearly catered to Nagi’s comforts.

And the costumes… From what Isagi could see, they ranged from thoughtful to lazy to ridiculous.

There was plenty to distract any interested eyes from a little disappearing act, assuming Isagi played his cards just right.

Isagi’s parents had raised him to always greet the hosts of a gathering, but that’d been easier said than done tonight. A group of grown-ass men, Reo and Nagi included, had been huddled around a gigantic marble coffee table before an even grander fireplace. Their voices were raised, their fingers were pointing, and King Barou, his plastic crown askew, was poised to throttle Batman Kunigami by the cape. All over the rules of Uno.

Nagi, dressed in a comfy cactus onesie, had then popped his head up from Reo’s lap and decided that mocking Barou’s dispute was a great idea: “‘She wore a crown and she came down in a bubble, Do’—oof!”

Wild West Sheriff Reo’d had his hands full. Isagi’d given a wave and a shout, both ignored, as he bypassed the scene.

Right… Egos and alcohol.

That little Uno circle hadn’t included the man Isagi wanted to see most, anyway.

Taller and more eye-catching than ever, Rin was impossible to miss. Isagi’d first seen him chatting with Nanase, who was wearing a Yuki Kawamura Grizzlies jersey, on the far side of the space, along an expanse of floor-to-ceiling windows overlooking the balcony and Tokyo below. Isagi’d slowly worked his way through friendly and masked faces, catching up and chuckling over war stories new and old, accepting a few d'Oeuvres and fancy liquor from the circling waiters. Rin’d seemed content to linger where he leaned against a column, watching the party unfold, letting guests and servers come to him.

Good.

There’d been no need to rush. Isagi’d figured a little patience would make this more fun in the long run.

Until a break in the crowd had given him an eyeful of just how undersized Rin’s top was.

Jesus fucking Christ.

Patience be damned.

Isagi had the perfect view of it now—damn near eye level—as he laughed at Rin’s vulgar gesture and nearly shook the alcohol from the two glasses he held. “Aww, c’mon. It’s a party, I’m just making conversation. And I brought you a refill. Here.”

With only a small grumble, Rin accepted the not-too-sweet rum cocktail and brought it to his lips.

“So what’s with the Macgyvered costume? I thought you liked Halloween. Oooh, did you lose a bet?”

Rin let out an aggrieved sigh. “I’ve told this story too many damn times.”

A grumbled complaint but not a no. Rin always benefitted from a little encouragement.

“Just the highlights, then," Isagi said over the rim of his drink; he tipped it enough for a taste, something to swallow. Just sweet enough. "For me.”

Rin raised an eyebrow but cooperated after another sip. “Take it up with the airline. Most of my luggage is somewhere in Europe; I improvised with what I still have at my parents’ place.”

“See? That wasn’t so hard.” Certainly explained the ridiculously tight fit of that damned turtleneck. Had Isagi seen teenage Rin wear it? He felt like he would have remembered the sight…. “And gold star for pulling together something more creative than buttoning a suit and calling yourself ‘Bond’ like the several Double-O-Sevens I see. Very lukewarm.”

Rin scoffed his agreement.

“At least Agent Karasu brought a little water gun filled with gin.”

Rin conceded a nod. “I’ll give him a pass for that.”

“Once you finally get your suitcase back, you’ll have to send me a pic of what you’d planned on wearing. Bet it was good.”

“Definitely better than breaking a pair of sunglasses just for an open bar and craft cocktails.” Rin took a long, appreciative drag of his mixed drink.

Isagi snickered and made the tactical decision not to call Rin out for clearly also wanting to see his friends. “Not a bad trade, though. Reo’s got good taste.”

“You don’t.” Rin inclined his drink toward Isagi’s Formula One jumpsuit and looked him up and down. “What, one sport isn’t enough for you?”

“Fast cars, adrenaline, and all that.” Isagi grinned. “I’ll take you to a race sometime, show you what all the fuss is about.”

Rin hummed and swirled his cocktail. “I can think of worse ways to spend my off time.”

“I think you’d like it.” Isagi spent entirely too much time thinking about things Rin would like, how he'd like them….

Rin extended a long finger from his glass, face and voice perfectly neutral: “So is this just a generic racing costume, or are you supposed to be wearing someone’s kit?”

Isagi's costume was cheap; its logos were very fake. 

“A friend’s.” Isagi rotated his backwards—authentic—cap to bear its emblem, his allegiance, …and the signature on the brim. He gave the ink a stroke, just because he could. “He’s been nice enough to trade autographs a few times.”

Rin’s eyes narrowed so slightly that anyone else may have missed it.

Isagi flipped his cap back the way it was and tried not to let the thrill, the squeeze and subsequent pounding of his heart, show on his face.

Maybe tonight really would be the night they’d cross the line they’d been dancing along for so long. It was about time. It was the right time, professionally and personally. The cocktails were working, the atmosphere was right, …and—goddamn—Rin’s longsleeve was at least two sizes too small. Maybe three.

Isagi let out a long breath. Not yet, not just yet. The night was still young.

He brought his eyes back to Rin’s face, not too concerned if he’d been caught staring—that’d only work in his favor. Subtlety hadn't gotten him far enough. Still, he needed to cut the tension before he climbed Rin in front of a full audience. “Is Sae still coming, too?” Yeah, mentioning his brother would do the trick.

“…He’s with the roach tonight, your guess is as good as mine.”

He laughed. Those two had the right idea…. If Isagi were a gambling man, he would’ve put money on them not making it out of their hotel room. It was kinda sweet, really, how horny they still were for each other. Now if the younger Itoshi would just get his shit together… “Please tell me their couple costume is Pest and Exterminator.”

Rin hid his smirk behind the cocktail Isagi’d brought him. “That’s what I told them.”

There it was, the perfect tone to leave on.

“Mmhmm, I’m sure that went over well. Oh, there’s Bachira! I’ve been waiting for him to get here, but bring me a drink later.” Isagi laid a hand on Rin’s arm, Rin let him. “You look good, Rin.” Isagi shifted so his back would block his next move from view, then slid his fingertips just a little higher, from forearm, to elbow, to firm brachialis. He leaned in close. “Even in a shitty, last-minute costume.”

Isagi heard a belated hmmph as he walked away.

As Nanase would say, the ball was in Rin’s court now.

 

 

Leave it to Rin to fight a good thing in the beginning. Two hours later, and he still hadn’t made his move.

Two hours of the satisfying weight of Rin’s gaze following him throughout the party; of occasionally meeting his eye with a smirk or wink just to call Rin out, just to watch how long it took him to look away. Lingering, holding out longer and longer every time… It was fun,—making eyes from across the room, their little staring contests, orbiting but never quite making contact—but Isagi wanted more. Now. Before he chewed a hole through his damn lip.

It was time to force Rin’s hand. Isagi'd hand him a layup or whatever—he had the capacity to follow two sports and two sports only.

He excused himself from Chigiri and Kurona and plucked a bright green gourmet lollipop from a roaming serving tray. He angled himself to give Rin a good—not perfect—view as he unwrapped it and slid it down his tongue, a thoughtful appraisal, before closing his lips around it.

Rin’s gaze had never felt heavier.

Mmmm…

Isagi wasn’t even making a show of his enjoyment; it tasted like sour green apple and caramel. Maybe even brandy? No, bourbon. Oh, it was good. Almost as good as Rin’s eyes honing in on his mouth from the side, blatant and hungry.

Isagi’s hands were woefully empty, in desperate need of a drink, as he slipped out onto the panoramic rooftop.

He bypassed the immense terrace for a more private sliver of balcony to the side. There were half a dozen small, bar-height tables spread across the area with tall torch heaters bordering each. Isagi chose the one furthest to the right, hidden from view. There was still a wall of glass behind him, but those windows belonged to an empty guest room.

No one else was adventurous enough to brave the wind that came with penthouse height. The heaters could only do so much, and the air had only gotten colder. He was alone.

Rin didn’t make him wait much longer. He emerged with two drinks in hand, the French door closing softly to mute the ruckus behind him.

The chase was nice, the chase was fun, but this little gesture of reciprocation…

“What’d you bring me?”

Rin stood to Isagi’s side, close but not close enough, and set the cocktails on the table. “They called it a Dark and Stormy.” A skewer of blackberries pierced the blood red drink like a dagger in an artery; black sugar rimmed the lowball glass. “It’s sweeter than I’d like but not bad.”

Something Isagi would like. He hummed and opened his hand to accept, holding the stem of his sucker like a cigarette. Rin slid it over—and didn’t allow their hands to even graze. Isagi did it for him, just the brush of a fingertip over a knuckle, a muffled tink of the stick on the glass. “…Nothing wrong with a little sugar, Rin.”

“Some of us take our conditioning seriously.”

“How can you be so sour on Halloween?”

Rin didn’t even roll his eyes, he just gave a pleased little smirk.

Even in the night, Isagi could see Rin’s lips were tinged ever so slightly berry.

Pretty. So pretty…

Oh.

The wheels in Isgai’s head began to turn like a film roll in a projector. He saw a vision so vivid, so moving, he had no choice but to make it reality: this lollipop sugar-coating the inside of that snide mouth, melting Rin into something nice and sweet. Some part of him, some innate sense, knew Rin would be into it, too—probably even more than Isagi.

Shit.

This was his chance to see how Rin’s mouth and always so enthusiastic tongue would behave in a different kind of passion, something far removed from football.

Isagi almost groaned. The image, the fantasy, possessed him; he was a man who’d found his calling.

“You alright?”

“Huh?” Isagi blinked like an airhead, still ogling Rin’s mouth, even as it frowned. “Oh. Right, yeah. I’m fine.” Damn, he had to relax and tap the brakes before he ruined any chance he had at making this dream come true. He'd had to completely forgo subtlety to get Rin this far, but now he needed a more delicate touch. 

“Hmph.”

He had to forcefully remove his eyes from Rin’s pretty lips as they moved around that familiar noise. Up wasn’t an option, Rin would see right through him. Isagi went lower.

Which did not help the fucking cause. Shit, he’d already made this mistake.

But there was a new twist now.

The canvas of Isagi’s jumpsuit was thick. His poor Waldo, on the other hand… The orange glow of the heaters provided just enough light to cast tempting shadows across the muscle of Rin’s chest. A perfectly placed white stripe offered more than contrast: a hint of color, even in the dim, where the thin cotton was stretched beyond its limit over built pecs and tight nipples…. A feast for Isagi’s eyes.

Dammit, Isagi needed something he could sink his teeth into, something he could devour. Some distraction so he could think and assemble the barrage of puzzle pieces.

He tore his eyes away from Rin entirely and brought his cocktail to his wanting lips, an unworthy diversion. He dragged the berries off with his teeth, licked the sweetness off the rim. Their flesh burst in his mouth, juicy and tart in opposition to the crunch of the crystals. Isagi’s racing mind began to slow as he chewed the situation over.

He and Rin drank in silence, slowly, side by side, watching the city beneath them flash and glow in the night as Isagi tried to exercise the same patience he’d managed to maintain all these years. This thing with Rin, beyond the fantasy, wasn’t something he wanted to rush. And he had a plan.

He tilted back his head and his drink. More than the propane flames above, the alcohol warded off the chill of the drink and air, warming his lips and chest. Rin’s assessment was right, it tasted good. Isagi just wanted sweeter.

Isagi set his empty glass on the table, a clink of finality, and returned the lollipop to his mouth. It took a few moments for his palate to appreciate the apple under the residual blackberry tang. It took no time at all for Rin’s eyes to abandon the cityscape.

Good boy, Rin.

Isagi dragged the lollipop down his tongue with a spinning flourish. “You’re staring,” he noted, lips skimming over the candy, eyes on the skyline. “You want a taste?”

“Hardly. How many different ways do I have to tell you I don’t have a sweet tooth?” Isagi could hear the eyeroll.

Isagi turned to face him, took one step into his space, and popped the sweet from his mouth. “We both know I’m talking about more than the sugar.”

Rin only raised an eyebrow as he set his finished drink next to Isagi’s.

Both good signs but not good enough.

Isagi took the next step, he laid a heavy hand down on the table in front of Rin and moved to squeeze between the table and Rin. Rin did as Isagi hoped: he backpedaled to avoid contact. Someone had to take the initiative, even if Rin pretended he didn't like it. Only two more steps, and Rin let his spine hit the glass, glacial eyes just barely wider than their baseline. Before they narrowed.

Isagi gave the lollipop a slow swirl in the air, closer to his own lips than Rin’s, and murmured, “Open your mouth, Rin.”

Rin bristled, like Isagi knew he would: “Fuck off. What do you think you’re—”

“I think you should trust me.” He lifted the lollipop closer to his target and watched as Rin almost raised a hand to slap it away, to spike it to the ground or launch it to plummet over the edge of the glass railing.

Rin glared, shoulders stiff, but he didn’t move.

So Isagi did. He lowered the offending lollipop to a safe distance, placing that hand on Rin’s shoulder. He’d introduced the idea like he’d wanted, like he’d needed to. Like with damn near everything, Rin had to get the bluster—the knee-jerk no that came from spite rather than considerationout of his system first. Rin just needed a little time to let the delicious idea sink in and marinate. Isagi would start with something he knew Rin would like. He'd help Rin loosen his lips and tongue, get him acclimated to the sugar. Isagi laid his free hand on Rin’s too-still chest to press him fully into the cold pane, sliding up his taut shoulder and neck, resting on his wind-flushed cheek; watching the grimace and suspicion fade and his posture soften with every touch. Until Rin was reaching for Isagi’s waist.

Yeah, Rin wanted this.

As long as Isagi had?

That was harder to tell.

Isagi had to stretch to push the broken sunglasses into Rin’s hair and beanie, a stroke through the dark emerald silk at his nape. Holding Rin’s eyes, he put the lollipop back into his own mouth for a quick suck, to make the flavor apparent, before standing on his tiptoes, leaning up and in; barely remembering to keep the sticky sugar out of the fray. In his defense, none of his many daydreams had involved Halloween candy.

Just before Rin’s eyes closed, just before Isagi’s did, he saw a little smile.

The rush of butterflies almost knocked him off balance.

Rin met him halfway, and Isagi's wet lips pressed to his in a chaste first kiss. Something so sweet that, two seconds later, Rin was holding him by the jaw, too; opening with the tiniest sigh, licking Isagi’s lip, inviting him inside. Finally, coming to Isagi with more than a mixed drink. Finally, doing what they’d both wanted for years. Isagi made him work a little harder, only letting Rin taste the sugar on his lips, not his tongue, even when Rin pulled him closer and sucked his lip. Only after he felt the vibration of a frustrated groan did Isagi give Rin what he wanted, what Isagi wanted: a true savoring of the sweet and sour coating Isagi’s mouth and tongue. They were groaning, their hands were pulling, their fingers were digging in—but Rin wasn't trying to take control. He just responded to what Isagi gave him, shit. Rin’s sunglasses clattered to the ground, along with the beanie as Isagi’s weight thumped him into the glass, nearly knocking the lollipop from his grip.

Rin’d had enough of a taste; his mouth was primed for something else now. Isagi broke their lips apart with a shove to Rin’s chest, shaking Rin’s hand from his face, dragging that thin fabric over the rock hard nipple his hand had landed on.

Poor Rin, Isagi’d warm him up soon enough….

The temperature was the last thing on Rin’s mind. Their kiss had released the tension from his muscles, any tightness from Rin’s face. He was breathing heavy, flushed and eager—probably annoyed that Isagi had cut it so damn short. Hopefully suspecting why.

This was it.

Slowly, so Rin knew exactly what was coming, so Rin had time to object, Isagi raised the lolli to Rin’s lips, wet and shining in the torchlight. Isagi held his breath, too afraid to spoil the moment, to break the spell. Rin’s heart pounded beneath Isagi’s palm, his eyes darted twice between Isagi’s and the lollipop, but his mouth didn’t seal. Even with the first touch. Rin shivered,—from the glass at his back and Isagi’s chilly fingers on his body, from excitement?—but he didn’t refuse. Even when Isagi caught the edge of Rin’s loose bottom lip with the globe, dragged it down, and let it bounce back into place.

If that wasn't the most beautiful thing he’d ever seen…

Isagi made himself look back up to search for any apprehension in Rin’s face. The night had expanded Rin’s pupils from the start, but now…

Fuck.

There was so little blue left, overtaken by curiosity.

Isagi’d always known Rin would like the feeling of something filling that mouth, something weighing on that tongue…. Rin just needed to let his ego go, he just needed to accept what Isagi was offering.

Isagi’s breath came out rough as he tap, tap, tapped the sweet against Rin’s lip, the glimmer of his white teeth; asking for permission, smearing sugar and dye as Rin let out his own shaky exhale. Isagi returned his gaze to Rin's. Please, please, please, Rin, he implored with his eyes. Trust me.

The lollipop tilted just a little in his grip. 

As if on instinct, the tip of Rin’s tongue had slipped out to swipe across his syrupy lips, to catch just a taste of the confection pressed there.

Isagi groaned, hot and loud in the cold desolation of the balcony.

Rin’s eyes widened, his fist clenched in Isagi’s costume—like he’d surprised himself, like hadn’t realized until Isagi’s reaction—but opened his mouth anyway.

That simple thing had Isagi’s blood rushing, careening toward his dick.

God, he needed to take this inside, horizontal.

Isagi pressed down to show what he wanted, that the lollipop was meant to stay, until Rin’s lips closed around it. That would hold Rin over for now. His hand slid down Rin’s shoulder and arm to the fingers clutching his jumpsuit.

Isagi’d feel worse about using one of the guest rooms like this, …if Reo and Nagi hadn’t disappeared an hour ago. If Isagi wasn’t well on his way to being as hard as all the marble in the place and Rin’s hand didn’t feel so big in his as he led them through the doorway. Isagi flipped on the lights; Rin locked the door behind them, both pairs of shoes clunked to the floor as they kicked them off in unison.

Fucking finally.

He tugged Rin toward the bed and pushed. The lolli almost flew from Rin’s mouth with the springy rebound, but he went willingly; he let Isagi crowd him higher up into the pillows, let Isagi straddle him and pointedly lower his body weight where it felt so good.

Rin really liked being the one pursued, didn't he? Isagi shoulda realized ages ago and saved them the goddamn time.

Rin’s eyes darted to indoor entry. He slurred around the object in his mouth, yet he showed no interest in removing it: “Zhe owher—”

Isagi cut him off with a hand to his cheek, turning Rin’s gaze and mind back to Isagi. “You didn’t keep a close enough eye on me, Rin. I locked it from the inside earlier.” Isagi smirked as he ground his ass down into Rin’s rapidly filling dick and took hold of Rin’s wrists, planting them on his outer thighs; working Rin up, demonstrating his expectations. “When I unlocked the one to the balcony. So relax”—Isagi stroked into Rin’s hair, watching the realization of premeditation dawn in Rin’s eyes, before kissing him again; just the corner of Rin’s mouth, until he slid his tongue in to flick against the sucker, against Rin—“and let me fuck your mouth.”

Rin let out a startled little noise around the lollipop, making it bobble against his tongue and lips, as his hips pushed into Isagi’s ass, as his hands pulled them closer.

Being right had never felt so damn good. Nothing had felt so good.

Isagi plucked the stem from Rin’s mouth and held it just off his lip. “Can I, Rin?”

With just a moment’s hesitation, Rin nodded.

Blood was rushing to his head as Isagi traced Rin’s Cupid’s bow, making the pretty arches shine. “Say it.”

“Fuck, just do it.” A tepid glare and an exaggerated grumble that did nothing to conceal his anticipation. Not when he'd pressed his lips a little closer, a little stickier, with each word. 

Warmth overtook him as his exhale came out choppy, as he leaned in close, a tantalizing friction through canvas and dark wash denim. “If you want it, show me. Lick it.”

Rin’s tongue caressed the candy bottom to top, top to bottom. No stalling, no wavering. Just two flicks of his tongue, and Rin's glare was collapsing under the weight of his desire. Isagi’s dick throbbed in his pants as Rin’s shoulders sank into the mattress, as his long lashes fluttered, as his tongue curved around the globe. 

Isagi could barely breathe, he could barely believe his eyes. He'd imagined his fingers in Rin's mouth—how much Rin would enjoy the pressure, the sensation—but this… He needed every fragment of focus he had left to keep a stutter from his voice and hips. “Good. Keep your tongue out,” he ordered as he pressed inside. He dragged it slowly up and down Rin’s tongue, careful not to go too far as he painted a green stripe; as he got Rin used to the intrusion. And Rin was just…letting it happen. Hazy eyes looking up at him through his lashes.

God.

Where was he supposed to look? The dyeing of Rin’s mouth or the steady death of sense and inhibition in Rin’s eyes?

The candy clinked like blown glass against Rin’s teeth as Isagi flinched. “Wider.” He didn’t recognize his voice, breathless yet firm and intent. He pushed it against Rin’s cheek to make a vulgar bulge. Still, Rin’s mouth remained loose and willing, tongue resting on his bottom lip as Isagi’d directed; no resistance, only pliant and sweet…. Aside from the unconscious little jumps of his hips, Rin was just…taking it. Isagi couldn’t keep any air in his lungs, his heart couldn’t keep up. He ran the candy along the roof of Rin’s mouth, hard palate to soft, back and forth; then just a little further, just enough to stimulate a gag. Rin groaned and nodded for more. “Yeah, feel it, Rin.” Isagi went deeper, and Rin arched into it, whining up to the ceiling once the reflex—once Isagi—let him, grinding his hard cock into Isagi. “No, no, look at me. Look at me and keep going.” It took a moment for his words to reach Rin, but he brought his chin back down, bucking into Isagi all the while. “Don’t stop." Isagi’s hand dug into the pillow for balance. “That’s the only way you’ll come tonight.”

Rin’s tongue made a useless flap against the candy as he fucked up harder into Isagi, nearly jolting Isagi from his lap.

Shit, Isagi was already hot and sticky. He pressed the candy down on Rin’s tongue—“Hold this for me”—to free up his hands and planted his knees more firmly on either side of his restless Rin to avoid being flung off the bed entirely as he unzipped his jumpsuit and shoved the sleeves off his arms.

Which only made Rin more desperate, putting those powerful thighs to use, driving into Isagi’s ass like his life depended on it. Like enough enthusiasm might just get him inside.

Mmm. Rin wasn't exactly wrong about that. 

“You gotta hold on to me tighter, Rin.” Rin’s renewed grip on Isagi’s legs neared painful. “Yeah, just like that.” Isagi leaned over Rin once more and reclaimed his new favorite toy; tightening his core to withstand Rin's hips, to keep his hand steady. “Now suck it.” He pushed the candy in, reached down to hold Rin’s face still where he wanted it. Rin released the candy on the backswing with a satisfying pop for the first few repetitions, but Rin began struggling to create a seal with his lips. The successive pops grew wetter yet quieter. Isagi wasn’t complaining, Rin couldn’t get enough. Isagi fucked Rin’s mouth with it over and over, until Rin was drooling from the corner of his glistening lips, bright sugar and saliva sliding down his chin as he let out tiny sounds of pleasure. On the next withdrawal, Isagi pulled all the way out, thumbed up the stream of spittle, and fed it back to Rin. Rin didn’t hesitate, he licked the syrup from his finger like an instinct—and Isagi barely managed to stay upright, leaning more and more forward to grind his dick into Rin’s stomach, to watch.

Keeping Rin’s skin clean was a lost cause. Rin had gone completely lax, melting more quickly than the candy in his mouth; his tongue lolled as Isagi played inside, as the globe gradually shrank. Even Rin’s thrusting had mellowed, continuous but subdued, leaving Isagi to move his ass for both their sakes. Rin was only occasionally remembering to make himself swallow, like it was no longer a reflex, just a distant afterthought; like he just couldn’t string the connections together. Like he was too focused on the feeling of Isagi fucking his mouth, making him gag, rubbing them together, to give a fuck.

“I didn’t know you could get like this, Rin,” Isagi breathed. The Rin beneath him was so simultaneously like and unlike the Rin he knew on the pitch; equally as out of it but so far from crazed and bloodthirsty. “I love it.”

Rin’s tongue hardly moved in response, just a hum. His wet eyes were so far out of focus, gone. Tears had collected in his lashes, his fingers were barely maintaining their grip on Isagi, green had trickled down his chin to stain the first stripe of his turtleneck….

“You’re so beautiful,” Isagi whispered as he removed the lolli. He held Rin’s face and squeezed just a little as he leaned in even closer, an idea he’d never even considered flooding his mind. Something dirty, something filthy. Something he knew in his gut Rin would love. “Focus, Rin. Look at me. Watch.”

Isagi sucked the candy into his own mouth, spun it on his tongue, but didn’t swallow. God, it tasted good. He popped it from his lips as he carefully pressed the thumb and index finger of his dominant hand into the hinges of Rin’s jaw. Slowly, so Rin could understand, so Rin could refuse, Isagi parted his lips just a little, just enough for his spit to begin to flow with gravity. Rin’s eyes went wide, recognition then cognizance rushing back. His hips went wild with a groan, abs and thighs pushing all the harder for friction, nodding as frantically as Isagi’s hold would allow.

Fuck.

Isagi had to keep himself from shuddering, from fucking hard into Rin’s tight stomach beneath him, as he watched Rin try to extend his tongue for a target; as the muscle rapidly began to weaken, fighting not to go limp again…. Those little whimpers of frustration and need…

Groaning as he did it, Isagi let his candy-colored spit fall into Rin’s mouth. Rin trembled at the impact, his eyes and neck rolled back, his hips worked. But his mouth didn’t move; he waited for direction, for permission. He kept his tongue flexed until Isagi pulled him forward by the jaw, looked him straight in the eye, and told him with a final squeeze, “Good boy. Now swallow.”

For a long moment, it looked like Rin truly didn’t remember how, fuck. But somehow, through true dedication, Rin swallowed…and managed to keep his mouth open so Isagi could watch his tongue and throat work from the inside. So Isagi could enjoy the view. 

He was dizzy, his head was going to explode.

Isagi almost collapsed to Rin’s chest as Rin moaned, open and honest, but he caught himself and his candy just before he crashed, before he jolted them from the dream. He tugged down Rin’s high collar to taste the sugary mess of his skin, to suck in a series of marks; meeting and matching Rin's grinding, Rin's gasps. Rin’s mouth had looked so pretty with something in it; it would look even prettier with something bigger, something that could stretch his lips and fill him up. He sucked harder before pulling off with an obscene sound, a poor imitation of his latest impulse, and licked up to Rin’s ear. “Want my cum next?”

Rin let out a rumbling groan and moved at lightning speed, a man resurrected. Like Isagi weighed nothing, Rin hauled him up by the ass to sit on his chest, lurching Isagi’s spine into a graceless bow with the momentum. He nearly lost the lollipop as he held his racing cap to his head through the whiplash, as he barely caught himself on a massive thigh. 

Shit, maybe he shoulda dressed up as a cowboy.

Damn, Rin.

Rin was yanking at his jumpsuit before Isagi even had a chance to right himself, before he could stick the candy into his grinning mouth for safe keeping.

Now that was more like the Licky Rin he was used to, taking what he wanted. And Rin wanted.

Rin was nuzzling his boxer briefs once they were exposed, licking up the front, tonguing into the wet spot with a groan, continuing past Isagi’s waistband to his navel; spreading Isagi’s legs even wider, sucking in his own dark bruises as Isagi pushed into him and moaned around their sucker. Rin kissed and marked and licked back down so his teeth could catch on the elastic and peel it down and awa—

There was a thud on the hall door, the handle was jostling— 

“Don’t break it, dem—!” 

The lock gave.

A priest and the subject of his exorcism came stumbling into the unholy scene.

No one breathed, no one moved, no one made a sound as the silent horror settled around them like mist.

The door closed with a soft click.

…Oh, shit.

Anybody but them

The blood was swiftly draining from Isagi’s face and dickbut not fucking swiftly enough.

No, no, no—!

Isagi’s waistband snapped back against his stomach, and like a knee to the diaphragm, it popped the lolli from his gaping mouth to land in a splat on his very naked, very arched chest. The candy tumbled down in slow, sticky motion…until it reached its only natural end: the tent in his underwear.

Fuck him.

In unison, the Itoshi brothers breathed out an “Oh my god” as the demon cackled.

“I knew it!” Shidou wheezed, doubling over with such delight that he nearly flung the plastic devil horns from his head. “I knew you two were fucking!”

I...don't really have an excuse for this. Hope you enjoyed my first RinSagi fic, and happy Blue Lock Halloweek (Twt | Bluesky | Tumblr)...and happy Swalloween!

Gold star if you find the almost direct quote from the manga. Lemme know if I need to add more tags or anything (I was russsshing), or if I should write more of these two. 🥴

(Why do all four of my bllk fics involve characters being pinned to walls and at least the mention of a hotel room?)

Notes:

Content warnings / squicks

Spit in mouth
Food (lollipop) used to trigger gag reflex in a purely sexual manner / to simulate oral sex
Wet & Messy
You could make an argument for a hint of subspace, but that wasn't really on my mind as I was writing it. I was thinking just Licky Rin with a very satisfied oral fixation. 🍭
