Isagi crept quietly out of bed, pocketing his phone and padding over to his nightstand. He wasn’t supposed to have his phone back this early, but he’d sweet-talked Anri after their celebratory dinner following the U-20 match. It took a little convincing, but she eventually gave in after Isagi’s persistence. ‘You did score the winning goal, after all. Just don’t let anyone else see you with your phone before tomorrow morning,’ she’d warned.
The sole reason Isagi wanted his phone back tonight, and not tomorrow morning, was for this. He pulled out a midnight blue sex toy, the one he’d been hiding in the bottom of his drawer ever since he came to Blue Lock. Up until this point, his hand was more than enough to take care of his sexual impulses. And the use of a vibrating cock ring certainly required more planning than blowing off steam alone in a bathroom stall. The buzzing sound produced by the motor wasn’t exactly discreet, and there’d hardly been enough time to relax in the days leading up to the U-20 match. There hadn’t been any urge or chances for him to use it.
Until now.
Rin hadn’t joined the team for dinner, a fact that Isagi cared about more than he’d like to admit. He didn’t feel guilty about that last goal, or how he’d stolen the spotlight from Rin. Weren’t they all playing for their own goals and futures anyways? After the final whistle, he’d seen Sae walk over to Rin, speaking for a few brief moments. Isagi didn’t know much about their sibling relationship, but from the way Rin’s face glowed and then promptly fell, Sae couldn’t have said anything positive.
Isagi had talked to Rin alone in the locker room as a way of checking in on him. He wasn’t sure what he’d been expecting. Perhaps the cold shoulder, or a short quip telling him to piss off. Certainly not a death threat, from someone who he’d begun to consider his friend—maybe something more—along the course of their rivalry. The aggression and ensuing frustration he’d felt after leaving Rin still coursed through him now. Practicing alone on the field would relax him, but he craved a different type of release. Those emotions clamored for an outlet, rising in the form of a tent in his pants.
He silently drifted down the empty hallway towards the shower room, checking to see if anyone else was awake. Everyone was sleeping soundly after the most exhilarating match of their lives. Isagi, though, felt like a live wire, his muscles still tense and taut. The sex toy remained tightly clutched between his fingers as he neared the end of the hallway.
The shower room was blissfully empty. He made a beeline for the showers, hurriedly rinsing himself off, his boner tapping insistently against his thighs. Carrying a towel to the deck, he eased into the steaming bath, not another soul in sight. Hot water washed over his shoulders, pouring liquid relief into his tired muscles. Reaching for his phone, he turned on the bluetooth function. It took a minute to pair with the toy, but eventually it buzzed to life, signaling it was ready for use.
Isagi submerged the toy into the water, carefully sliding the ring onto his stiffening erection. It settled around his base with a squeeze, pressing against the throbbing of his cock. This was his first time using a bluetooth-operated sex toy, but it couldn’t be that difficult. He stared at the options on his screen, unsure of whether to test the preset patterns or venture into live control.
Preset patterns seemed like less work, less intimidating. His fingers pressed a sequence at random.
The phone fell from his hands, clattering to the ground. Oh. Oh. Isagi wasn’t expecting such intensity. The room had been dead silent earlier, but now his startled moan was traveling across the rippling water, echoing off the walls. The sensations were entirely unlike anything he’d experienced before, unrelenting and demanding even at this idle speed. He buried his face into his towel to hide his gasps, but the pattern he’d selected was a gradually building tempo of pleasure. Every nerve within his body was engulfed with burning hot desire, craving more, more, more. The tortuously slow pace was enhanced by the silicone circling his cock, constricting and digging into his boner.
Isagi raised his head from the towel with a whine, not noticing the nearby footsteps through the cloudy haze of pleasure building higher and higher. The sequence reached its peak right as somebody’s thighs stepped into his line of sight.
Isagi’s gaze slid upwards, falling right into Rin’s teal eyes.
⛓ ⛓ ⛓
Rin was uncharacteristically restless, tossing and turning in bed throughout the night. He found himself in the yoga room at midnight, terse, grating breaths leaving his lips as he reflected on the U-20 match. Everything was going perfectly until the last minute.
Breaking the ball free from Sae’s command in an uninterrupted 1v1, then proceeding to thoroughly crush his brother with a ruthless goal of his own—that was something he’d dreamed of executing for far too long. To have Isagi snake through the field and steal that goal was an infuriating slap to his face. The moment Sae uttered those words of praise solely directed at Isagi was the final nail in the coffin. All of the blood, sweat, and tears he'd culminated were lost to Isagi; his efforts went entirely unrecognized by his brother.
Utterly unforgivable. Rin cursed, feeling his temper spike again despite his controlled breathing. Yoga wasn’t going to cut it tonight. He picked up his water bottle, the one he’d so stupidly taken good care of after Isagi handed it to him during their last training camp. Back when he’d perceived Isagi as an ally, perhaps the closest person who could be considered his friend. Whatever their relationship was.
That had completely gone to hell. Isagi was nothing more than his rival now, practically begging to be destroyed after getting between him and Sae.
He approached the entrance to the shower room, so caught up in his thoughts he barely noticed the sounds of someone else in there.
Not just any person. Isagi was sitting in the bath with his back to Rin, propping himself up with his elbows atop the deck. Eyes narrowing, he started towards the showers in the direction opposite of Isagi. Seeing his face would only fuel his fury.
Rin was in the midst of pulling his shirt off when Isagi’s voice finally began filtering through his ears. He stilled, checking to see if he’d heard correctly.
Isagi was whimpering. He at least had the decency to muffle himself with the towel clutched harshly in his grip, but that did next to nothing. Even across the room, Rin could hear his drawn out, unsteady gasps.
Rin hated how those noises beckoned straight to his cock.
Grabbing a towel and shoving it into his waistband, Rin stalked over, prepared to tell Isagi off. He had yet to notice Rin, his unseeing eyes glazed over, fixated on the phone that lay nearby. Rin glanced at the screen, watching as a cursor climbed upward at a languid pace. What the fuck was Isagi doing?
It clicked for Rin as the cursor peaked, plateauing for a few seconds before dipping down. At the same instance he realized Isagi was playing with himself, their eyes locked with an electric jolt.
Isagi choked on his breath, clearly not expecting anyone else to be up at this hour. Panic set in, partially from being discovered by none other than Rin, but mainly from the possibility of not reaching his climax. How the hell was he supposed to finish now, with Rin’s eyes boring into him, observing his every move? Isagi opened his mouth, not exactly sure how he’d explain himself, when the vibrations gripping his cock suddenly skyrocketed.
“Rin?” He’d meant for it to be an irritated snap, but it spilled forth as a moan. Fuck. He needed to disconnect his phone before he quite literally orgasmed in front of Rin. Something fell to the ground—was that the water bottle he’d given Rin in the training room? Think later, act first. The undulating, maxed out pace of his toy was making it impossible to think straight. Isagi’s hand reached sideways, searching for where he’d dropped his phone earlier.
Instead, his palm made contact with a heavily muscled thigh, and he squeezed reflexively. I know I left it here. Where— Isagi’s sluggish gaze zeroed in on the device sitting in Rin’s possession.
Fuck. “Give that back,” he rasped out. His voice was coming out all wrong, the rolling tempo on his cock squeezing out the last remnants of restraint and dignity he had left. He bit his lip feverishly in a desperate attempt to avoid moaning. Isagi was so close. He could feel the pleasure mounting at his base, straining against the ring restricting his blood flow. Euphoria crawled upwards in a teasing drag all the way to the tip of his cock, where it suddenly stopped, receding backwards.
Isagi blinked, stupefied by the abrupt loss of vibration. He pulled his head up, searching for the culprit.
Rin sat cross-legged in front of him, an unreadable expression on his face. His fingers hovered over the vibrator controls, analyzing, calculating. Isagi watched, not quite registering that Rin was the one who’d withheld his orgasm, when his fingers tapped the screen again.
A scream was ripped from Isagi's throat. The pleasure he’d been denied came back in full force, reverberating through all his limbs. Isagi balled his hands into fists, pressing his forehead against the cool tiles as the reality of the situation sunk in. If there was anything more embarrassing than Rin walking in on him masturbating, it was this. Being at Rin’s complete mercy, unable to cum unless he permitted it.
He wouldn’t beg. No matter how hard it got.
At least that's what he told himself. Through his ragged breathing and addled senses, he struggled to curse Rin out.
“Turn that fucking thing off,” he spat out, the arching of his back betraying his true desires. Isagi fought for any semblance of control, attempting to steady the uneven panting escaping his mouth. They both knew it was useless. He was utterly helpless, every oscillation of pleasure dictated in the palm of Rin’s hand.
Rin observed with twisted fascination as Isagi’s back curled in a pleading bow, conflicting emotions flitting across his face. There was a specific set of sounds Isagi made when he was about to cum, Rin quickly realized. A slight hitch in his breathing, followed by high-pitched hyperventilating. Rin paused the toy every time he heard that, his eyes darkening with desire at Isagi’s reactions. The agonized pleas that were torn out of his lips each time sent a thrill coursing through Rin’s cock.
A sadistic smile played on his lips as he watched Isagi near his climax over and over again, unable to do anything except go completely stiff, his throat seizing with anticipation. Isagi was so pitiful like this, his limbs jerking and twitching like an obedient puppet. One that only Rin had complete control over.
Rin repeated this cycle, relentlessly building Isagi up just to tear his pleasure away in this torturous game. Beg for it. Isagi needed to suffer more, until he was reduced to nothing but a sobbing mess. Rin’s sadistic side was far from being sated. He blazed with the desire to dominate Isagi, to fuck him until he was entirely subservient to him. Teach him a lesson so harsh he’d never forget the consequences of getting between him and his brother.
That could be saved for another time. He wanted to take Isagi apart intimately, in a place where the two of them couldn't be interrupted. Not in this shower room.
Isagi was babbling something. A quiet ‘please,’ laced with utter shame. Or that’s what Rin thought. He could barely hear Isagi’s voice over the staggering flow of blood threading straight through his own cock. His rival’s face was flushed a deep crimson hue, contorted in aching desperation.
Isagi’s mind was completely fogged over, overcome with the primal need to cum. Embarrassment was beyond him at this point, and so was begging. A part of him believed he should be worried about how this would change his relationship with Rin, and what that could entail. But he was past caring. All he could focus on was the punishing, pulsating pressure wrapping him so tightly. It was unbearable, the blood in his cock circulating and pounding against the constrictive ring.
The vibrator paused once more, sending him into a frenzied state as he chased his release. “No, no, come back,” he choked out. Exhausted and teased to his limit, Isagi reached a hand forward, clutching Rin’s left hand; the one that wasn’t chaining and controlling his climax with casual, deliberate strokes of his fingers.
His hand trembled atop Rin’s, fragile and breakable. Rin assessed him with a cold, indifferent gaze as Isagi tried to catch his breath. He wasn’t done with him yet. Without warning, the toy sprang to life, at a more brutal pace than before. His eyes narrowed as Isagi’s grip tightened, clenching hard enough to bruise.
Isagi felt like he was verging on the brink of insanity. Entire worlds collided before his eyes, ones encompassed in sinful lust, dripping with pleasure. The droplets set his body ablaze, swallowing him up with the promise of his impending orgasm. Close. Close.
Until Rin yanked it out of his reach again.
His head fell forward with a defeated sob. It was too much; the overstimulation was going to kill him. He couldn’t read Rin’s mind or puzzle together what exactly he wanted from him. His last resort was to beg with what was left of his broken voice. Please, please, please.
A low chuckle emanated from Rin, undeniably pleased with Isagi’s display of submission. The sides of his lips curved upwards in a derisive manner. “I couldn’t hear you, Isagi. Ask properly." His command carried a condescending lilt, contempt oozing off his words.
Isagi's lips parted to sound his request, but something within him hesitated. He hiccuped a sob, pressing the back of his hand into his mouth as his body quivered. Rin leaned forward until their faces were dangerously close, using his fingers to start the cycle on the vibrator again.
“Say it, Isagi,” Rin hissed, looming over him as Isagi convulsed.
Isagi's next words tumbled out without a second thought. "Please let me cum, Rin." A distressed whine escaped his lips, his pupils endless pools of mindless lust. Rin drank in the sight of tears streaming down Isagi’s face, brought forth by his relentless, unforgiving edging.
"Your orgasms belong to me now. Do you understand?"
Isagi thrashed, barely lucid through the overstimulation. Panic flashed through his eyes as he noticed Rin's fingers threatening to stop the vibrator.
"Isagi." A warning.
Rin was expecting a verbal confirmation.
"I—" Isagi heaved, not fully processing what he was saying. But then the toy stilled, and all of his hesitations drained out of his mind.
"I understand, fuck, just please let me cum." Isagi's reddened cheeks were dripping with tears, splashing into the water below. Something inside Rin snapped.
He finally obliged, shifting the vibrations to the highest setting and holding them there; granting Isagi permission to cum.
Rin wouldn’t go easy on him, though. He’d never be soft on Isagi again after the events of last night’s match. Rin hated how his facade of control always seemed to slip when he was around Sae. He hated that Isagi’s name coming out of Sae’s mouth was what pushed him past the edge on the field.
Isagi was going to suffer for that. He fisted a rough hand into Isagi’s hair and wrenched his head back hard as Isagi cried out in pained shock. Rin towered over him, leering, his aura oppressive and domineering. Absolutely nothing was going to escape him. He planned on watching every millisecond of Isagi’s orgasm.
Isagi struggled uselessly, the unnatural position forcing him to stare directly into Rin’s eyes as he came, pain and pleasure crashing in an overwhelming tsunami over his senses. His breathing hitched, spilling over in trembling, shallow gasps as he went utterly limp in Rin’s hold.
He didn't let Isagi break eye contact, his grip tightening every time Isagi's gaze so much as faltered. Rin soaked in every detail of Isagi coming undone, heat continuing to pool below his core and settling between his legs. There was something so enticing about Isagi writhing beneath him. That spent, humiliated look in his eyes because of what Rin had done to him.
“I own you, Isagi. Don’t you fucking forget that.”
Rin finally released Isagi’s hair. He drooped like a wilted flower, exhaustion evident in his laboured breathing. It was as if a set of floodgates had opened during his orgasm, leaving him utterly subdued after the liquid ecstasy had run its course. His eyes were fluttering shut when a firm hand tilted his chin upwards.
Rin’s eyes surveyed Isagi’s tear-streaked face, roaming over his flushed cheeks and drool-slick lips with barely concealed satisfaction. Watching Isagi beg and cry for him had excited him more than he’d anticipated. His erection still throbbed insistently in his lap, demanding to be taken care of.
Good thing they had two whole weeks ahead of them.
He drew Isagi close, whispering a sinister promise into his ear. “I’ll see you over the break.” Rin seared a possessive kiss against his collarbone as Isagi shuddered beneath him. He quelled the impulse to lick the glittering tears off Isagi’s face, deciding he looked prettier with them staining his skin. Maybe next time he’d leave a permanent mark.
In one smooth motion, Rin stood up, leaving Isagi in the water as he strode away. He knew he wasn’t imagining the rings of desire burning into his back.
Isagi’s wrecked gaze followed him all the way out of the shower room.
