Work Text:
Hospitals were once an unfamiliar environment for Tsumugi Aoba — before he became friends with a terminally ill billionaire.
Even after several visits, he still doesn't think hospitals are particularly pleasant places to hang out. Regardless, Tsumugi finds himself in the ICU of the most high brow hospital in the city. He can't help but conclude this place is unsettling, sterile and uncanny from the hyper modern decor to the automaton-esque employees that seem to stare right through him.
The entryway to the hospital is one of the fanciest rooms he's ever been in. Tsumugi wonders what infinity fountains, floating staircases, and abstract art installations contribute to the healing process, but they certainly don't make him feel any less out of place here.
Or maybe that's just his anxiety talking?
Tsumugi takes a centering exhale in an attempt to settle himself. He shouldn't be hovering around the lobby anyway, this isn't a casual sight seeing excursion. He's here on important business — Eichi Tenshouin summoned him specifically, and who wouldn't visit their best friend when they're down and out in the hospital?
Tsumugi hurried here so fast he tripped on his way out the door.
But he remembered everything — he quadruple checked to make sure. Tsumugi's backpack is stuffed with unfinished music compositions, manilla folders containing Yumenosaki student profiles and idol uniform sketches. Whatever Eichi might need, Tsumugi made sure to bring it all.
He hurries through the halls, failing to spot anything to help him find his way, until a nurse desk catches his eye. The tight ponytailed woman on duty is casually clicking through computer work. Tsumugi approaches her, and dips his head, “Excuse me, ma'am? Can you help me find my friend's room?”
The nurse's eyes flit up from her monitor and she smiles amicably, “Of course. What's your friend's name?”
“Eichi Tenshouin.”
She blinks, “... I'm afraid I can't disclose any information about sensitive patients without the proper clearance.”
“O-Oh!” Tsumugi sheepishly shifts his glasses, “I forgot, Eichi told me to use a passcode: ‘Bluebird'?”
The nurse cocks a brow, then gives Tsumugi a once over. Her eyes drift from his scruffy mop of raven hair to his humble button up and slacks that are slightly disheveled from rushing here, then back to his nervous smiling big bespectacled face, “... I see. Right this way, Sir.”
The nurse rises from the desk and leads Tsumugi to a sealed double door labeled ‘Staff Only’. She swipes her ID in the card reader, and the lock mechanism clicks open. The nurse bows her head, “Mr. Tenshouin is just inside.”
Tsumugi mirrors the deferential gesture, “Thank you, ma'am.” Then he proceeds alone into the isolated wing of the ICU. A striking white hall stretches ahead of him, a handful of patient rooms pass on his flanks, but only the room at the far end is occupied. Tsumugi approaches the closed door and cautiously raps his knuckles against it.
“Enter.”
It was only a single word — but the confident and noble voice was unmistakably Eichi's. Tsumugi bubbles with enthusiasm, and pushes through the door.
The interior is about three times the size of the average hospital room. There's a massive floor to ceiling window granting a grand view of the city skyline from their lofty vantage. Tsumugi spies the Yumenosaki green on the distant urban outskirts, but their academy and all the drama it contains is just a measly speck from here.
The medical equipment looks state of the art and pristinely maintained. A subtle green like fresh spring is the predominant color of the impersonal decor. There's a picked over plate of ‘hospital food’ on a tray beside the bed — including a medium rare filet mignon and black truffle risotto.
Then, in the corner of the room, Tsumugi spots his friend. Eichi is sitting up in a lounge chair, and prodding at the device he always wears around his wrist. The so-called ‘Eichi meter’ that monitors his illness in real time. The display is currently orange, which Tsumugi knows is only one step away from the red that indicates critical condition.
That's concerning, but Eichi doesn't look ill? No more than usual, anyway. He seems alert and devoid of pain — although he's dressed in a thin hospital gown that exposes the frame of bones in his waist and shoulders, and there's an IV line running to his wrist from a drip feed behind the chair.
When the door opens, Eichi's gaze flicks up from the wristlet. He forms a relieved smile when he identifies Tsumugi, “Good, you're here.”
Tsumigi mirrors a much brighter smile, “I came as fast as I could! How are you feeling?”
That question disrupts Eichi's cordial demeanor. His lips thin back into a grouchy line, “I am perfectly fine… even if this blasted thing claims otherwise.” He gives another irritable poke to the health monitor, then devolves into prodding and glaring at the screen once again, “I think it's malfunctioning.”
“... Huh? Like it's broken?!” That spikes Tsumugi's nerves. How can anyone know if Eichi's ok if his meter isn't working?!
“Precisely. It's been reporting my condition as dangerous for almost 48 hours now, but I've felt entirely normal the whole time,” Eichi's tone sharpens with frustration for the wrist monitor as he jabs away at it, “Yet in spite of my certainty I am forbidden from leaving this place until this piece of junk gives its blessing.”
“... Oh.” Tsumugi scratches his head, “Well isn't it better to be safe than sorry? If there is something wrong, then you're exactly where you need to be!”
Eichi's eyes flick up from the screen, “Are you insinuating that you understand my body better than I do?”
Tsumugi jolts, “... Huh?”
Eichi barks a volatile retort — harsh enough to displace his carefully lain curtain of hair, “I know my symptoms! And I'm telling you that I am perfectly fine! I don't have time to waste away trapped in here when there's still so much work to be done!”
Tsumugi's eyes blow wide, “S-Sorry, Eichi! That's not what I meant at all! But, a-are you ok? You seem… tense?”
Eichi takes stock of himself — then resets to careful angelic demeanor, “... As I already said, I am fine. Please try to remember that time is of the essence if we want to achieve our dreams. Every second I waste in this place feels like torture when it could be put to use elsewhere.” He clenches his fists in his lap and glares at the wall.
Tsumugi frowns with sympathy, he doesn't want Eichi to run out of time to complete his dream either, and unfortunately, Eichi's time is more finite than most people, “... I understand. You're like, the hardest worker I've ever met, even when you're sick. Sorry you have to stay in the hospital, but I made sure to bring all our stuff with me? I've got all your war plans, so we can work on whatever you want now!”
Eichi's gaze flits back to him, “... Your efficiency is commendable, but that is not why I called you here.”
Tsumugi tips his head, “Oh? Is there something else I can get for you? I'll take care of it, whatever you need-!”
“Are you wearing it?”
Tsumugi's rambling stalls. That seemingly innocent question completely shifts the pressure in the room. Just like that the frail framed and infirm hospital patient wearing only a flimsy pastel blue gown feels immense.
‘It’ could only be referring to one thing.
Tsumugi compulsively fidgets, feeling ‘it’ shift and slide against his clothes. He's used to ‘it' by now, enough to forget about ‘it’ most of the time. ‘It's’ been part of him for a while now, “Yeah, I am. I never take it off, just like you told me.”
“I would like to verify that, if you'd be so kind.”
… Oh.
THAT'S why Eichi called me here?!
Tsumugi doesn't mind being called to heel for ‘that’. He's shocked, but he would do anything for Eichi… and ‘that’ just so happens to be his favorite task to fulfill for Eichi.
He loves serving Eichi's needs.
Cause that's what friends are for, right-?
“Tsumugi?”
Tsumugi shakes away his stupor, “O-Of course! I'll do anything you need me to! But… here?”
“Hm.” Eichi tips his head with an innocent smile, then rises weightlessly from the lounge chair — and rips out his iv. A crimson bead pools from the injection site and trickles down Eichi's arm, but he pays it no mind.
“A-Ah!” Tsumugi yelps, “Is that safe-?!”
Eichi glides across the room and snatches his wrist, “It was just fluids, and I'm more than capable of drinking my own water, even if the damn doctors don't agree. Come.”
Tsumugi complies with that command without protest. Eichi drags him by the wrist deeper into the room, through a peripheral door into the bathroom, then he shuts and locks the door behind them. The bathroom is featureless white, devoid of decor and detail but sterile and sharp smelling as everything else. There's just the bare necessities, a pure white porcelain toilet, shallow porcelain sink, and a small shower stall that does not look up to lofty Tenshouin standards.
The aspiring idols sharing the tiny tiled room paint a harsh contrast. Tsumugi awkwardly tangling his fingers — when Eichi takes point in front of him in a broad stance, then lifts his chin with a stare cold enough to elicit a shiver, “Show me.”
“... Y-You mean-?”
“Take off your clothing.”
Tsumugi shivers again. It's easy to comply with the innate authority in Eichi's voice, even when he uses that gentle tone and volume. It's easy to follow Eichi's orders, even an order that would probably sound disturbing to most people, “... Right.”
Tsumugi's uncertain hands fall on the top button of his shirt, but fail to make any further progress. I guess should do this… sexy, right? He's staring right at me, so I should give him something to look at, right?
Eichi's stone faced expression is impossible to read at the moment, but it certainly doesn't seem flirty.
Or patient.
In the end, Tsumugi elects to strip his clothes as quickly as possible. His shaking hands make quick work of his pants as he awkwardly kicks them off, then he pulls the shirt over his head rather than battle the buttons. He shimmies out of his underwear next until he's amassed a pile of clothes on the floor. That leaves him entirely naked.
Except for ‘it’, of course — ‘it’ being the solid gold chastity cage sealed around Tsumugi's cock.
At least, he assumes it's solid gold. He never asked, but it was a gift from Eichi Tenshouin. So it's probably real gold.
His modest sized dick is contained within a rigid nest of gold that guides it into a flaccid resting curve. The metal is shiny enough to bounce the bathroom lighting back, and the cage is sealed by a golden ring locked behind Tsumugi's package. Naturally, Eichi holds the only key to unlock his cage.
Eichi's stern expression softens into a satisfied smile as he admires the nervous statured and cock caged bluebird fidgeting in front of him, "I'm pleased that you followed my instructions.”
Tsumugi presses his pointers together, “Course. I'm happy to wear it.” The cage was a gift from his best friend. Not your average friendship bracelet, but surely infinitely more meaningful by some metrics? Even if it's kinda weird, Tsumugi's cage means a lot to him, cause it's a symbol of his bond with Eichi.
Eichi fishes a handkerchief from his pocket, strides over to his side, and claims the cage with the dainty fabric square. He rotates the chamber to study varied angles with clinical interest. Tsumugi gulps a swallow and stays stiff as a statue while his friend examines his dick, “I don't see any smudges… That makes me very pleased.”
Tsumugi's smile stretches with pride, “Mhm! I'm careful to only touch it when I have to, just in the bathroom and showering, and I always clean it after.”
He isn't supposed to touch the cage — or the contents inside of it. That's, like, the point. If Tsumugi did touch his shiny golden cock trap with indecent intent it would leave fingerprints. That's what Eichi was looking for — evidence of him violating the most intimate order his friend has ever given him.
The cage felt so cold the first time it sealed around his dick. The sound of the lock clicking shut echoed around his ears. He can still recall the sound with ease, the sound of an unbreakable promise being forged.
“From now on, you're only allowed to cum if I give you permission. Do you agree?”
Of course Tsumugi agreed to those terms, it's his pleasure to follow Eichi's orders. He would never question his brilliant friend, even if he doesn't fully understand the purpose of this order.
Maybe it's one more way for Eichi to hoard control? He craves control, presumably because he’s helpless to control his own mortal fate. Maybe Eichi likes removing any doubt from their… situationship? It's not like Tsumugi can betray him if he's literally under lock and key. The cage ensures the bluebird inside can never stray from his owner.
To be honest, it doesn't really matter why Eichi needs this, cause Tsumugi likes it too.
His shiny cold cage is spotless, no matter how thoroughly Eichi searches for a smudge. Tsumugi would never disobey and touch it needlessly, he keeps it shiny as a prized jewelry piece. Even when he wakes up hard or gets a random boner, he's gotten pretty good at ignoring the discomfort until it goes away. Cause he promised not to cum unless Eichi gives permission, and he would never break a promise to his best friend, no matter how uncomfortable it makes him.
Besides, when Eichi does give permission, then he gets to let out all of his pent up frustration. The euphoria of permission is almost intoxicating.
For now, Eichi seems happy to keep him caged and untouchable. He finally relents, slips the handkerchief back in his pocket, and rises to reclaim his noble height advantage, “Well done. You've passed my inspection with flying colors.”
“Great!” Tsumugi bubbles gleefully, “So, um, do you want me to put my clothes back on now?”
“Hehe-” Eichi gives a flighty chuckle into a hooked finger, “Of course not. You think I'd call you all the way here just to inspect you?”
Tsumugi's cheeks burn with understanding, “... Oh.”
That really is why he called me here?! Noble and refined Eichi Tenshouin summoned Tsumugi by name to his private hospital room… for sex.
It feels like a dream, to be honest.
This is far from their first time, but Tsumugi still feels like the luckiest guy in the world whenever Eichi shows interest in him. He's amazing. An angel in the flesh. Confident, intelligent, fascinating. Out of my league-
Simply put, sex with Eichi is a privilege he'll never pass up.
But there's something that gives Tsumugi pause. It's not that he doesn't want to do it — but his gaze still flicks automatically to the orange warning screen displayed on his friend's wrist monitor.
Eichi notices, and his eye twitches, “I told you, I am fine.”
Tsumugi gulps around a bundle of nerves, “I-If you're sure?”
“... You know what I need. I will feel better than ever if you give it to me. So will you help me, or not?”
“... Of course I'll help you.” Tsumugi wants it too, and surely Eichi knows his limits, “So h-how do you want me-?”
Eichi's cold fingers snake around his wrist once more, then he uses his arm as an anchor to spin him towards the sink. Eichi presses the captive arm into his back, flattening his tummy on the sink porcelain, then looms over his shoulder, “Don't worry, I'll guide you.”
Tsumugi's heart leaps with excitement for their sudden proximity — and from Eichi's whispered promise to personally lead him to shared glory, “Ok! Please, do!”
Eichi strips the glasses from Tsumugi's face, and sets them on the sink. Then his nose brushes through Tsumugi's shaggy hair as he hovers near his ear, “It's better this way, wouldn't you agree? To let me dictate your story? Right down to the climax.”
Tsumugi eagerly nods, “Absolutely! You're so smart, I trust you to know what's right way more than me!”
“Good. That's wise of you.” Eichi releases his wrist. Four feather light fingers glide down his spine then nimbly invert when they reach his rear, “I'm going to start now.”
“O-Ok! Do whatever you need to! I'm happy to help!”
Eichi pants a hot breath of enticed approval. A brief delay to fetch a bottle and apply the contents, then a pair of lubed fingers cup under his ass, squish to test the firmness, then slip between his cheeks and elicit another shiver, “I know what's best for you, Tsumugi." His body tenses instinctively when cold and lithe fingertips prod his rim, but Eichi isn't deterred. The first joint of a finger jabs into his tightly sealed hole, “I know you better than anyone.” Tsumugi gasps and hunches forward harshly enough to loosen his entryway. Eichi capitalizes, and dips his finger into the knuckle.
“Ah-!” The tension gets to him, Tsumugi lets his weight fall back onto Eichi's chest and rolls his hips to guide the finger in and out of his body, “I know you do! You're m-my best friend!”
Eichi doesn't deny that, and that's enough to preserve Tsumugi's joy. The finger worms around his ass as he guides it to slip in and out. Eichi gazes down at the weightless little bird that's collapsed onto his chest with an expression that seems… amused? But happy too. And that's all that matters.
Tsumugi turns forward, and finds a beautiful image reflected in the mirror over the sink. Two aspiring idols, intimately close. An angel bestowing grandeur upon the mortal raven he's taken under his wing. Eichi admiring him from his slight height advantage while Tsumugi swoons from just a single finger. The little bird is smiling ardently, casting a visage of his pure joy in the glass — but then Eichi's stare joins his in the reflection.
When their eyes lock in the mirror, Eichi forms a cold frown, and the prep halts.
Tsumugi furrows. What's wrong? The reflection looks beautiful to him, but something about it obviously upset Eichi.
Does he not like their aligned faces, the stark mismatch between noble and common? Tsumugi's buck naked body, unremarkable in every way except for his beautiful golden cock cage? Or… was it the image of Eichi's frail framed body, captured in the mirror wearing only an unflattering blue hospital gown?
Not clear. But something soured his mood.
“Are you ok, Eichi-?”
A hand falls on the back of Tsumugi's neck, and pushes his face down into the basin of the sink until he's entirely bent over it, “Stay down.”
Sadly, Tsumugi loses the lovely view in the mirror, but he settles for this compulsory eye full of white porcelain, “OK. I will.”
He can't see anything, but he hears shifting fabric. Then an opened bottle cap and more lube spreading followed by stroking flesh. Then he feels heat prod his rim, but the probing point is wider than a finger this time. Eichi's tip tests his nerve riddled tightness.
“I-I'm ready.” Tsumugi bows his spine to offer himself.
“Mmm.” Eichi's honeyed hum scrambles any focus left in his brain. A hot tip threads the needle of his neuroticism — then Eichi thrusts his hips and Tsumugi receives a surge of smooth penetration.
It's euphoric to be filled by him. No matter how many times Eichi fucks him it's a hit of pure elation every time. Tsumugi giggles with excitement into the sink while Eichi delves until he's balls deep, flattening his ass and pinning him to the sink. Then his satisfied groan bounces around the surrounding tile.
Wow- Tsumugi can't see anything but sink. And this soulless clinical room is the opposite of romantic. And it's cold enough in here to make his nipples perk. And he obviously can't touch himself with the cage keeping his pleasure contained.
But none of that matters. Feeling Eichi's cock slot smoothly inside his body is one of the hottest things he can imagine. Which means he can't help but get turned on — and because of his cage, that's not ideal.
Tsumugi's cock swells with excitement, and consequently strains against its golden confines. He's only half hard, but his usually cozy cage is already feeling uncomfortable. Chastity cages aren't supposed to hurt if they're properly sized, but Tsumugi's cage is… a little too small.
But it was a gift? He doesn't want to insult the beautiful gift Eichi gave him by complaining about it. So he endures the discomfort.
He's already swollen enough to stuff the golden snare. That's ok. He's come to like pain when it's a gift from Eichi. Every struggle he endures only improves the reward after. He's happy to endure anything to earn Eichi's permission. If Eichi gives him permission to cum, the climax feels about a billion times more intense than just an average orgasm.
That's a load bearing ‘if’ — but Tsumugi would rather earn his release. His pleasure means so much more if it's a gift from Eichi.
Tsumugi whines from equal parts pain and elation, but compliantly presses into Eichi's hips to assist the penetration.
“That's good. Stay just like that for me, little bird.”
The praise perks his cock up again, but the cage traps him in a flaccid angle and punishes his pleasure.
Eichi starts slow. Slipping out of his ass then pressing to his core. Driving repeatedly until boney hips squish him against the cold sink after every languid press. He repeats the leisurely fucking, as if savoring Tsumugi's unconditional surrender, and feeding off his needy whimpers.
Then the hand holding his neck snags a handful of Tsumugi's raven hair, and yanks.
A harsh thrust, and more gifted pain.
“EICHI!” Tsumugi yelps.
“Hgh-” Eichi's breathy grunt echoes.
Rougher now. Eichi uses his hair as an anchor and fills his gut with frustrated friction. He's not always this aggressive, but obviously he has some irritation to work through.
Tsumugi sincerely hopes that by the time Eichi is finished their joy is mutual. In the meantime, he grits his teeth, and drips a couple of hot and hazy tears through his sealed eyes that plink when they hit the sink.
Tsumugi's hands are clutching the sink for balance tight enough to turn his knuckles white. He can feel Eichi's other hand propped beside his on the sink, close enough to his to brush thumb and pinky every so often. But the fleeting touches aren't enough. Tsumugi would love to be guided by both of those brilliant hands-
As if Eichi is remarkable enough to read his mind, a second hand grips his waist, hoists it to a harsher angle then the grip in his hair shoves his cheek flat to the sink. The next penetration splits stars through his vision.
Harder still. The sound of their slapping skin echoes around the bathroom as Tsumugi is filled with a blur of penetrations. His tears flow, and he whines with pain.
“Such a sorrowful song you're singing… but I thought you loved assisting me?”
“I do!!”
“Then shouldn't you be grateful for this opportunity?”
“I-I am! So grateful! Thank you, Eichi!”
Anything for you. Anything to be useful for you. That's all I want to be-
Tsumugi yowls for more as rivers run down both cheeks — Eichi shoves him down and renews his force with an eager growl.
Getting fucked by Eichi is so hot. Eichi's so hot. Tsumugi can't even see him, but he can still hear his aroused panting when he finally finds a pace that satisfies his volatile mood. He can feel both silk soft hands treating him with the firm guidance he desperately needs to lead him to their shared destiny. It's all so fucking hot-
“You love this, don't you?”
“Yes! YES-!”
Tsumugi's cock bulges against his cage. It hurts really bad now. He's hard enough to ache even without thatches of metal digging into his dick. Pain is outweighing pleasure. He can't focus on much beyond the agony crushing his cock. His headspace is empty of everything but the ecstasy of pleasing Eichi-
Then a cell phone rings — and the ruthless fucking instantly stops.
The stock ringtone bounces around the small tiled room. A bizarrely artificial sound when Tsumugi's ears were filled with their shared sex sounds only seconds ago.
Without a word, Eichi pulls out — leaving Tsumugi alone, bent over the cold sink and despondently empty. He turns his head to watch Eichi stalk away, lift his phone to his ear, and accept the call.
“This is Tenshouin.”
It's almost creepy. Business as usual? — even though they were interrupted in the middle of that frenzied fucking. Even though Eichi is currently half dressed in a hospital gown that's hanging open in the front to free his standing erection. When he notices Tsumugi observing his appearance in such an absurd state, he turns his back to avoid his eye, but the gown looks ridiculous from behind too…
In spite of all that, business as usual.
It's like a slap to the face. Eichi just set him aside like a miscellaneous distraction even though Tsumugi felt like they were sharing cloud nine a moment ago. But Eichi knows what's best. That call must be important.
The voice through the phone is too garbled to understand, but Eichi is intently listening. His eyes widen, and he nods, “... Yes! That's wonderful news! With your cooperation I will be able to proceed to the final phase of production!” He chats back and forth with the caller, “... Oh. An… in person meeting?” Another mumbled message that only reaches Eichi's ears, “I agree. As soon as possible would be ideal. Time is of the essence.”
Meanwhile, Tsumugi just waits. Until Eichi needs him again.
But to be honest, his tightly caged cock is killing him. Maybe I can just… shift it? Not for pleasure, but just to lessen the pain? That's not against the rules right? Tsumugi reaches between his legs-
“STOP!” Tsumugi's head whips back over to find Eichi fervently glaring at him with the phone still held to his ear, “Do not touch that.” Tsumugi balks, and gives a sheepish nod in understanding. Eichi resumes cordial business demeanor, and turns away to resume his chatter, “Forgive me, my pet was misbehaving. What were you saying?”
The phone call drags on while Tsumugi stays still as a statue and tries to think about anything other than the cage. Maybe his arousal would go down if Eichi's voice wasn't so beautiful, but that voice is gonna define the idol industry some day, and it captivated Tsumugi a long time ago.
Naturally, he endures the maximum constriction until the business is complete.
Finally, Eichi wraps up the call, “Thank you so much for your assistance in this matter. I will see you soon.” He hangs up, treads back over to the sink, and pouts like a grumpy child, “You almost did something reprehensible while you thought I wouldn't notice. I'm disappointed in you.”
Tsumugi pales, “I-I swear I wasn't trying to touch myself! It just-” His lip wiggles pathetically around his admission as his eyes fall to the floor, “it hurts. I'm sorry, Eichi.”
Eichi's playful pout dissolves into a blank facade, “... I see. Your cage isn't supposed to cause you pain.”
“... I know. I didn't wanna seem ungrateful, but it's really tight when I'm turned on. It's not bad when you're distracting me, I guess I kinda like the pain then? But it's all I can think about otherwise. I'm sorry.”
Eichi ponders that explanation. Then he pinches Tsumugi's chin, and guides him to rise until he's standing up straight and their faces are nearly level. Eichi's unreadable eyes flit over his worried features, "... I forgive you.”
Tsumugi ogles starry eyes back, then bobs his head, “Thank goodness! So, was your phone call good news? You sounded happy.”
“Yes. It was,” Eichi's eyes flit to his periphery as he reflects, “a Genuine Revelation.”
“Huh? What do you mean?”
“You'll see soon.”
That excites him. Eichi's surprises are always beyond his wildest dreams. Tsumugi clutches his fists, “Alright! I can't wait!”
Eichi tilts his head and mirrors a cherubic grin, “Me either. Now…” The hand holding Tsumugi's chin glides around to support the back of his neck, “May I resume where we left off?”
“Of course!” There's nothing he wants more, “Anything for you, Eichi.”
“Then I have one more favor to ask of you.”
“What?”
“Close your eyes, and do not open them.”
“Ok.”
Just like that, Tsumugi is ceremonially blinded. He seals his eyes, regretfully denying himself the view of their perfect unity in the mirror — but then Eichi guides him once more, and that's all he needs. Eichi's glorious vision is enough sight for both of them.
Arms tangle around him, then his naked back melds to Eichi's slim chest. This time Eichi reciprocates the pressure when they fit together. A spindly fingered grip seals around Tsumugi's throat to trap him in intimate proximity, then Eichi guides his cock until he finds the hole, and slips easily back inside.
Tsumugi croons with pleasure when he's filled again. Eichi is firm, but not aggressive anymore. Hands clutch around his throat and seal over his chest as Eichi determinedly builds friction between them. Tsumugi endures another round of ignoring his own neglected dick in favor of focusing on the one inside of him, but there's an abundance of Eichi to distract him from the ache now. He's back on cloud nine again.
Then, something unprecedented.
For the first time ever, Eichi's palm slips down his naked tummy — and melds around the cage. Eichi clutches the golden cock trap in his fist as he maintains the pace of fucking him from behind.
It's the most maddening thing Eichi's done to him yet. Tsumugi can feel sublime body heat permeating through his cage. Like a heavenly aura radiating on him. The hand isn't giving any actual friction to relieve his tension, but it's euphoric to be so close to contact. Eichi Tenshouin is almost touching his dick-!
But, wait… won't this leave fingerprints?
It definitely will. But it also can't be against the rules if Eichi is doing it? Eichi knows best, so it must be fine.
Tsumugi smiles from ear to ear, and savors every gifted sensation. Eichi's fist crushing around his cage, the boney hips repeatedly squishing his ass flat to claim as much as he can. Eichi moaning right beside his ear and nibbling on his jaw as Tsumugi cries from his gaping mouth.
Take it all. My sight, my body, my pleasure. Anything for my best friend-
“Ah~!” Eichi's climax culminates in a heavenly chorus that bounces around the bathroom. Fingernails claw into Tsumugi's throat as intimate pulses of heat seep into his body. That's extremely hot too. Eichi's cum inside of him is physical proof that he was useful for him.
Eichi's face collapses against his hair as he catches his breath. Then, audible confirmation of his wish come true, “You've made me very happy, Tsumugi. You may open your eyes now.”
His joy is so potent that his eyes shimmer when they open, “I'm so glad to hear that.”
Just a bit more guidance. Eichi turns them face to face, “For everything you've done for me, you deserve a reward. You've earned this.”
The sound of clicking metal echoes in Tsumugi's ears — then a much louder metal clank when his golden cage falls away and lands on the tiled floor.
With the turn of a key, his hyper sensitive cock is abruptly freed from its vice. Tsumugi cries out in relief and collapses to his knees when the pressure is removed, but he still peers up at Eichi for reassurance.
“Go on. Enjoy it.” Eichi gives a slight smile that could only be described as ‘fond’, then slips out the door of the bathroom.
The instant it closes, Tsumugi follows those orders. He falls on his rear with his back flat against cold tile, then reaches between his legs, and claims his dick in his fist.
It's all so fresh in his mind. Every erotic detail. And Eichi is still close too. He can hear his slight footsteps right on the other side of the door, and he can easily recall all the intimate details from their most recent coupling. Tsumugi jerks and jerks while appreciating the phantom touch Eichi's hand left around his throat, and the haunting echoes of feminine moans he always makes when he nears his end, and the stretch and mess he left inside-
It doesn't take long. A rocket-like strand of cum fires through Tsumugi's fist, and he cries like he's been reborn. One more gift from Eichi. He strokes strand after strand until the clinical white bathroom tile is marred with his mess. It's been weeks since the last time he was allowed to cum, and the relief is so immense that it draws a couple more tears to his eyes.
A knock on the bathroom door makes his head whip up, “I'll be going now, make sure to clean up.”
“... Wait, what?” Tsumugi's head whips around, “Going where?!”
“I have a meeting to attend.”
He scrambles to the door and yelps back, “But I thought you couldn't leave? What about your gauge-?!”
“An important meeting. I can't afford to miss it, our dreams hang in the balance. Please inform the nursing staff that I've checked myself out when you're finished, I'm counting on you.”
Tsumugi hears the outer door of the hospital room open. He's going already-?! He must've gotten dressed while Tsumugi was occupied, “W-wait! Aren't you gonna put my cage back on?!”
“... There's no need.”
The outer door shuts, and heel clicking footsteps tread away down the hall
The glow in Tsumugi's chest fades along with his friend's absence. Eichi really left? Which leaves naked him stranded in the middle of a cold tile floor with a handful of cum and cock.
But this isn't right? Eichi always puts the cage back on himself afterwards, to make sure it's secure.
At the moment, the beautiful golden symbol of their bond is just laying on the ground like refuse. Tsumugi gasps, and scrambles over to reclaim his cage from the floor. He regrets leaving it there, his treasured belonging shouldn't be treated so haphazardly-!
But then he makes an observation. There are two golden objects shining on the empty white tile. Tsumugi hovers over them on all fours with wide wavering eyes that struggle to understand what they're seeing.
His cage — and the key that unlocks it.
Eichi left both behind.
