Chapter Text
He could only describe the area he manifested in as desolate. A war? Not possible, it lacked destruction. Buildings were not destroyed so much as they were eroded.
As a servant, he had ample knowledge of proper human history, that included this modern era. Asphalt roads were filled with rubble and store signs dangled over buildings by the last of their screws, an abandoned city.
The rippling energy from his summoning faded away and his eyes rested on the only other person in sight. Skepticism grew in his mind, rather small for a saviour of humanity was he not? A head of sleek dark hair and a soft face.
Not much of a fighter was he?
Richard’s gaze fell upon the man’s eyes, and something stowed in his chest. “I ask thee,” he approached, “art thee my Master?”
The man nodded, holding his hand over his chest. If the command seals weren’t proof enough, the tone of his response made it definite, “Yes.”
He was decisive. The look in his eyes was the battle-hardened expression of a man who has fought countless wars, witnessed the fall of kingdoms, and insurmountable losses. The wear of experience was written on his face, and yet he still burned with determination.
A smile crept up Richard’s face, Yes, he’d be more than fine.
His eyes raked over the man’s figure. God must have blessed him for every good deed he had ever done to have such a beautiful master. A handsome face, lips so supple he wanted to brush his thumb over it, and a full-body uniform that clung to all the right places.
Contradictory impulses raged inside him, torn between an intense desire to protect and ravage him.
Richard let his hand free from his sheath and took the mage’s hand, pressing it against his chest. What things could he accomplish with the last master of humanity? The thought had his heart pounding with anticipation.
“How exciting! My name is Richard the Lionheart and my blade shall be yours, my master.”
His master jerked at his touch. He had such small hands. “Nice to meet you, I’m looking forward to working together.” He had such a pleasant smile.
Richard squeezed him, enjoying the way his palm was large enough to envelop his fist whole. “As am I.”

Ritsuka tossed a few sticks he found into the fireplace. He thought about cooking some of the canned food he found in the abandoned house’s kitchen but decided he should ration his supplies for now.
According to Da Vinci, Mash was “rejected by the singularity”, so he didn’t have much to work with. Thankfully the abandoned buildings had stocks of food he could grab whenever it was necessary.
There were all kinds of stores. Department stores, warehouses, abandoned convenience stores, there was even a gunshop not far from his spot. Not too bad of a situation considering his past experiences.
Da Vinci had briefed him on the situation when communications were still functional.
“The bad news is none of the servants from Chaldea are compatible with this singularity. We can’t send anyone to help.” Da Vinci explained, “The good news is there doesn’t seem to be any major threats in the area, but you should try and summon a servant as soon as you can. You think you can use the leylines?”
“Yeah, I can manage.” Drawing a summoning circle wasn’t that hard, he just hoped it wouldn’t take too much out of him, his face was burning up every now and then. It couldn’t have been a good sign. “I think.”
Da Vinci smiled on screen, “Alright. One more thing, the singularity is minute but it operates on some of its own rules. None of our servants can manifest there because it operates on fictitious traits and rejects certain aspects of reality. Our servants here don’t fit in so to speak. In your case, the trait was assigned to you. Whether this is because you’re human or just compatible with the singularity, we can’t say for sure.”
“Is it dangerous?”
Da Vinci ducked away from the screen, Ritsuka could hear her muttering something to someone but couldn’t make out what it was.
“Guys? You still there?”
“We’re here.” Da Vinci seemed to hesitate, “Ritsuka, are you familiar with the omegaverse?”
“It’s a bit hard to forget.” He says.
Osakabehime featured the same kind of stories during the last Servantfes, he didn’t want to admit he ended up reading all of them in his own free time out of curiosity. Unforgettable was one way to put it, but traumatic would be more accurate.
“Good. That saves the need for explanations.” Da Vinci sighed, “The singularity works the exact same way.”
Ritsuka blinked dumbfoundedly.
“–Yep.” Da Vinci pulled up a chart of his biography, a bunch of complicated charts and diagrams he’d never be able to read himself. “I’ll put this as bluntly as I can, you’re an omega in this singularity. It’s not the best situation to be in, but if things go well, then you shouldn’t face too many obstacles. My main concern is your servants.
“I’m going on a hunch here, but this probably means that any servant you summon will automatically have similar traits applied to them too. We don’t know how dangerous that can be, but as a contingency we suggest you find suppressants some… ….ants ex…., you m…t n… ….ta-”
That was when communications stopped working.
Obviously becoming incapacitated by an urge to nest was out of the question, so the first thing he did was find suppressants. They were surprisingly easy to find, a bottle of pills with incredibly convenient labelling: “Suppressant” with the greek letter Ω beside it.
They were the first thing at every rundown convenience store and pharmacy in the area so he threw several bottles into his rucksack. Better safe than sorry.
After that he drew up a summoning circle to summon Richard.
The saber was a bit intimidating, very enthusiastic too. Being around someone like that for too long would be exhausting but Richard was so charming he couldn’t say no to any of his ridiculous requests. A two hour long discussion of why King Arthur was his idol? What the hell, sure.
That was yesterday, now Ritsuka was sitting on the couch while Richard set up the fireplace.
He inched a little further from the fire and tugged at his collar, whatever omega trait made him heat up, he despised it. Burning up at random intervals for no apparent reason wasn’t exactly as exciting as it was terrifying.
“Are you alright master? Do not hesitate to tell me anything, Although I am a King, I am more than eager to nurse you back to health if need be.”
He felt sluggish yet alert, like running on five cups of coffee and zero hours of sleep. “No it’s fine… Just hot.” He sighed, fishing through his rucksack for the pills.
Richard frowned at the sight of the battle and slapped it out of his hands. Most of the contents spilled on the floor.
“What are you doing?!” Ritsuka picked the bottle up, luckily half of the pills stayed inside.
“Those pills are senseless Master, it only delays the inevitable and brings you pain.” Richard crossed his arms, “You would be better off coming to me for help.”
Ritsuka rolled his eyes, “Yeah I think I’ll pass. Thanks though.” He dry-swallowed a couple, it numbed his senses before gradually cooling him down.
Richard stared with an unapproving glare, “Well, the offer always stands master.”
“Mhm,” his eyelids were heavy. “Thanks Richard. I’m gonna turn in for a bit.”
“Not to worry, fatigue never ails me when there is something worth protecting.” Richard smiled, “Get some rest. I will watch over you.”
“You’re the best.”
Richard chuckled at that.
He was getting the hang of dealing with Richard. The saber was a lot more impulsive than most. Similar to some of the berserks on Chaldea, if he took care to listen to him every once in a while he wouldn’t be too much of a problem.
The last thing he heard was Richard tapping his thigh, humming an old ballad from his period. Exhaustion took over and he collapsed on the couch. The pills always made him sleepy but that was a small price to pay, they were practically his lifeline here.
***
Ritsuka was dozing off to Richard’s long-winded prelude to Galahad’s quest for the grail when the familiar heat rose in his chest again.
Grabbing four bottles of suppressants back at the store didn’t seem like an overly cautious decision anymore.
He was nodding along to Richard’s rambling as he fished through his rucksack and felt nothing in the back pocket.
Huh?
Ritsuka dug around, sliding his hand past tightly packed clothes and equipment. The front pocket, the side pockets, the little nook inside the biggest compartment meant for toothbrushes, he went through the whole thing but arrived at nothing.
Oh no. No no no no no.
He tossed the bag upside down, shaking everything out in the hopes that he’d missed something, but in the scattered pile of assorted accessories, equipment, and tools, it was nowhere to be found.
Richard had stopped his story at this point, the way he looked at him was so devout with worry he almost forgot he was still in trouble. “Is everything alright Master?”
Ritsuka struggled to breathe, “Listen, my suppressants, the ones in the small orange bottles… have you seen them?”
“No.” Richard responded bluntly, a bit too quickly to not be suspicious. For all his charm and wit, he was a terrible liar.
“Richard goddamn it, what did you do?”
“Heinous medicine like that is no good master,” Richard spoke with the obstinate tone of a purist, “matters of the body are best managed naturally so I got rid of them.”
Ritsuka’s heart pounded, thrumming what felt like straight-up fire through his veins. He knew far too well how these things played out, and he wasn’t sure if he was ready for that kind of thing.
He’s avoided situations like this so many times in the past, surely… surely he’d make it out this time too.
He eyed his surroundings, to the left was the window, to the right was the stairs to the upstairs bedroom. He could lock himself there for a while but knowing Richard he’d probably try to bust the door open to “help him out”.
Booking it was not going to be an option. He had no Mash, no other servants, no communications, no weird McGuffin or spell that could possibly help him here. For the first time since he’d become a master, he felt like there was nothing to keep this from going further.
“Richard,” Ritsuka panted, “i-it’s too inconvenient isn’t it?” He tried to appeal to reason, the idea of just saying ‘please give me back my pills’ didn’t seem like it would work.
“Nonsense, all you need is willpower.” Richard beamed, taking his hand. “However, if needed, I will make certain it becomes more than an inconvenience, Master.”
This arrogant, fine, tall, and handsome royal prick .
He cursed Richard’s arrogance. For better or for worse he knew Richard meant no real harm by his actions, he was just… headstrong and old school.
“Richard, that’s not-” Waves of heat pulsed from his chest to his throat. He bit his lip. “That isn’t the point.”
The fire crackled, filling the quiet desolate space between them. He couldn’t help but wonder why the city was abandoned in the first place, or where he was supposed to go from there, suddenly feeling the kilometers of emptiness surrounding the two of them.
“You’re burning up.” Richard stared, an intensity to his gaze that made Ritsuka’s shoulders tense.
Richard tucked a lock of his hair behind his ear, burrowing his nose into his neck with a deep breath. Ritsuka leaned into it, he didn’t even realize he was willingly baring his neck.
“The more you repress this, the more painful it will be.”
Richard sat closer, their thighs brushing against each other. Richard loosened the collar of his own shirt, a thick must permeated through the space between them.
“I cannot bear doing nothing when you are like this in front of me. Let me quell the fire burning inside you, master. Let it out.”
A sharp almost alcoholic scent shot up his nose and Ritsuka’s knees buckled. An aching emptiness coiled low in his stomach and the last of his resistance snapped. A thick heady scent burst from his body, sapping his strength away with it.
He didn’t realize how much he’d been holding back this whole time. The relief that came with letting it all go was so dizzyingly warm he almost fell forward.
Richard caught him just in time and pulled him flush against his chest, pressing their bodies together.
A light flush colored his servant’s face, “You smell incredible… like the flowers and dew from my homeland.” He licked a stripe along the column of Ritsuka’s neck, before sucking on the crook of his neck. “I want to breathe every inch of you.”
“Wait I… I-” Ritsuka huffed, every touch, sound, and sensation threatened to send him under. “Ah fuck, I can’t take this anymore….”
Richard crushed him into the couch, the cushions sinking under his weight. The crackling fire filled the silence that came with every other touch, embers danced around the fireplace. Shadows wavered with the flicker of the firelight.
His voice deepened, “Is that a yes?”
Ritsuka shuddered, sounds too drawled to denote any form of resistance.
‘Use a command seal’, his mind screamed. This was a dangerous situation, any form of escalation or loss of control was a risk he shouldn’t be willing to make. He knew that, and yet, he didn’t have the willpower to do it.
His servant didn't even try to reign in his impulses, kissing every inch of exposed skin he could find.
Richard pulled at his shirt more desperately with each touch, failing to tug the custom tailored wardrobe over Rituska’s head, awkwardly pulling his face.
He mewled, stomach coiling at the cold fingers trailing down his stomach. “The back. There’s a button on the back.”
Ritsuka heard the click of it unclasping and Richard tossed it aside. Richard smashed their lips together like he was trying to eat him alive.
Richard’s favorite thing to do was very clearly kissing, not stopping for even a moment’s breath. It was warm and sloppy, his tongue rolling around his mouth to taste everything inside.
Drool spilled down the side of Ritsuka’s mouth till it was pooling on the floor. It was frenetic. Cathartic. Just letting it all go for once in his goddamn life…
His mouth went slack, his toes curling, his body convulsing at the lack of breath, dick straining against his pants as it throbbed to full-mast.
A string of saliva connected them when Richard pulled out, he pecked Ritsuka one more time before pulling his chin down, letting the warm liquid of his mouth drip down onto his master’s tongue.
“This is how we did it when I was alive, master. Swallow, the more you do, the easier everything else will be.” Richard rasped before kissing him again. He could feel Richard driveling into his mouth, forcing him to swallow lest he wanted to choke on it.
He gulped it all up, fully at Richard’s volatile whim. Richard wasn’t lying, swallowing it all was helping, but unlike the suppressants it made his body burn hotter, like it was trying to exacerbate the flame till it burned itself out.
A stickiness dampened his pants, he could feel it leaking out of him. He didn’t even know that was possible. Suddenly he felt hyperaware of every little sensation around the area.
In that moment it became clear to him that he was experiencing something that couldn’t and shouldn’t have ever occurred, a carnal fantasy that wasn’t supposed to exist, and God did it feel like it. So good but somehow so wrong.
Richard peeled off his jacket and shirt. Ritsuka was almost ashamed at how impatient he was to see Richard’s lightly sculpted figure.
Hands slipped into his pants and the mage’s indecision was gone, eyes closed and back arched slightly as Richard worked his hand through the snug fit of his pants and boxers, brushing against his twitching cock.
“Just take them off.” Ritsuka begs.
Richard scrunched Ritsuka’s pants down to his knees. Obviously it wasn’t enough, because when he pushed Ritsuka’s thighs apart they got in the way. He growled and yanked them clean off, neither worrying about where it landed.
Red eyes raked over his figure voraciously, “You’re so beautiful master, I wish I could have you all to myself like this all the time.”
Richard fumbled with his belt, eyes firmly on his as he freed his throbbing dick.
Ritsuka’s eyes glazed over him like it was a show, raking over taut muscles, abs, the v-line that trailed to Richard’s dick… he had to swallow the lump in his throat just to breathe.
Richard leaned forward, grinding his cock against the cleft of his ass. “Master… I don’t think I’ll ever get enough of you. I would rather gaze upon your eyes than the stars above, the way they scrunch whenever I touch you and the blood rushing to your cheeks…” He shudders out an exhale, “You drive me to the brink of madness.”
Ritsuka was blushing hard enough that nothing he said would have made it any worse, so he just begged. “–Fucking hell, Richard just stop talking and fuck me already.”
Richard’s eyes darkened. “I’ll make this quick for you.” He popped it in slowly, only stopping once he was hilted inside.
“Ngh! Fuck .” Ritsuka threw his head back into the couch. Ecstatic now that the ache inside was finally, finally starting to quell. “Richard. You were right, this feels s-so… nghhh-!”
The intensity almost ran him unconscious. He felt every ridge, the way it throbbed inside him, gradually chipping at the deep-seated hunger that had been eating at him since he first rayshifted.
It was so much his ears rang, slick ran down his thighs where they were connected. His vision darkened at the sides.
“Breathe.” Richard seemed to remind Ritsuka as well as himself.
“You…” Richard growled, “Damn it all, this feels better than I anticipated.” Richard closed his eyes, sweating bullets with his hips flush against Ritsuka’s. He grunted every time his hole clenched around him, fingers digging deeper into Ritsuka’s waist, resisting the urge to move.
Ritsuka rolled his hips, desperate for friction, but Richard snarled and held him there. “Stop.” he hissed.
“P-please move already!” Ritsuka whined.
Richard bit his lip, shaking his head vehemently.
“Why not?” He groaned, “I’m dying over here….”
“I have overestimated myself, Master. The slightest touch more and I will not be able to guarantee your safety, I’ll lose control…” Richard moaned, failing to hold his breath.
“Then lose control,” Ritsuka pleaded languidly, “I’ll reign you in if I have to, that’s my job isn’t it?”
He yelped as Richard folded in half, pistoned into. He could barely register the blinding ache in his lower back because of how full he felt.
Ritsuka wrapped his legs around Richard’s waist, pumping his own dick to Richard’s pace as he chased more of those shocks that made his entire body convulse.
“Master~” Richard husked obsessively, grinning sinfully at the sight of Ritsuka jacking himself off to his ministrations.
Richard’s voice slipped him further and further into a euphoric state. His insides felt like they were melting away, but more accurately they were getting churned up by the man pounding into him so hard the couch creaked against the floorboards.
Richard kissed his face, trailing down his neck till he arrived at the crook of his neck. He started sucking again, teeth grazing against his skin with each lick.
The pace shifted, erratic and animalistic. The couch creaked along with the ungodly sounds of Richard squelching into his slick entrance.
Ritsuka could feel the base of his shaft begin to swell, catching on his rim with each thrust.
“Richard I-I’m gonna-” He babbled as he painted his stomach and chest in his own release.
Slick gushed from his ass, spilling out of where they were connected. A small part of him worried that wouldn’t go back to normal after he got back to Chaldea.
“Ah!” Ritsuka spoke slowly, voice pinched by moans. “F-fuck, Richard you need to pull out.” Ritsuka mewled with so little conviction it didn’t even convince himself.
Richard growled, baring his teeth against his neck.
“-Ah! Hey no, get off!” Ritsuka pushed his head away, but his feeble human strength didn’t do much.
His servant’s pace slowed, thrusting in harder and deeper, doing his to press himself flush against his ass. The swell at the base of Richard’s dick struggled to pop in.
Ritsuka had to hold his breath to ground himself and remember that he needed this to stop before they did something they’d regret. He wasn’t sure if knotting him would result in something taking root inside but he wasn’t about to try and find out.
He used a command seal.
For a moment, Ritsuka was afraid, it didn’t seem like it was working. Richard growled, the veins of his arms and hands bulging as he resisted the command. But then he pulled out, settling his erection on Ritsuka’s stomach and jacking himself off to completion.
Thick scalding ropes of cum shot all over him, searing his stomach, chest, and face. It even got into his hair. It gave off such a sharp smell he could vaguely taste it.
Richard fell on top of him, chest rising and falling with each breath. The warmth of their coupling radiated around the room.
Richard only got off when the fire went out, he put his clothes back on and mumbled something about getting more kindling and that he’d return as soon as possible before going out the door.
“Fuck…” Ritsuka took a deep breath. He struggled to wrap his head around everything. The burning ache in his stomach had faded, but he remembered vividly the way it felt being fully impaled on Richard’s cock.
The flush on his face returned. He wiped the cum starting to thicken off his cheek, promising to never let himself be as lecherous as he was today.
At least he had an excuse…
