Chapter Text
"I’ve got you," Avery murmured, his voice dropping an octave, abandoning the nervous stammering from seconds ago.
With a terrifying surge of strength, Avery scooped him up as Derlord instinctively locked his legs around Avery’s waist, his arms clutching the slime’s shoulders. He was painfully aware that they were still connected, the movement of the walk jostling Avery deep inside him with every step.
"Avery—ngh—put me down," Derlord hissed into Avery’s neck, though his grip tightened.
"Almost there," Avery hummed, unbothered by the weight, walking with a steady rhythm that made Derlord’s head spin.
When they reached the bedroom, gentleness had never been the intention. He dumped Derlord onto the mattress, the sudden impact knocking the breath out of the knight. Before Derlord could scramble away or even orient himself, Avery was there. He pulled out suddenly only to immediately grab Derlord’s hips.
He flipped Derlord over like he weighed nothing, shoving his chest into the mattress and hauling his hips up high. Derlord scrambled for purchase, fingers digging into the sheets, but Avery was already lining up.
He pushed inside in one smooth, devastating slide.
"Mngh-Fuck!-“
Derlord head flew back as Avery bottomed out, hitting his prostate with a force that felt like a collision. The overstimulation was immediate. Derlord’s body, already primed and wrecked from the couch, couldn't handle the sudden, intense friction. Without remorse, he grabbed Derlord’s waist, anchoring him, and ground his hips forward, ripping another orgasm out of the knight before he could even beg for it.
Derlord shattered. He came violently, dry-heaving against the sheets, his body convulsing in a series of sharp, painful spasms that left him completely boneless.
Silence fell over the room, broken only by the wet, ragged sound of their breathing.
Avery leaned down, resting his cheek against Derlord’s sweating back, his hands soothing over the knight’s trembling sides. "You okay?" he whispered, sounding genuinely concerned despite the havoc he’d just wrought. "That was... a lot."
Derlord couldn't even speak. He just nodded weakly into the duvet. Avery hesitated, then shifted slightly, the movement re-stimulating Derlord’s raw nerves.
"Can we... do you want to keep going? I'm not... I'm not done yet, Der."
Derlord squeezed his eyes shut. His pride was a stubborn, dying thing, but it was still there. He refused to tap out. Not to a slime.
"Fine," Derlord croaked, lifting his head just enough to glare at the headboard. "But... slow...j-just give me a minute.”
"Slow," Avery agreed, sounding relieved but full of awe, "I can do slow. Thank you Thank you-."
He began to move again.
True to his word, the pace was agonizingly sluggish. Avery dragged himself out until he was barely there, then slid back in with a thick, heavy pressure that stretched Derlord open inch by inch.
It was torture.
The slow drag gave Derlord’s body time to recover, blood slowly rushing back to his groin. He felt himself beginning to harden again, pressing against the mattress, but the pace was maddening. He needed release. He needed to focus on something other than the crushing weight of Avery inside him.
Desperate, Derlord reached down. His hand reached between his body and the mattress, fingers brushing against his semi-hard length, seeking the friction that would speed things along.
Avery stopped with a click of his tongue, "Tut-tut.”
Before Derlord could wrap his fingers around himself, Avery’s hand shot out. He grabbed Derlord’s wrist, yanking it back.
"Hey—!" Derlord protested, trying to twist free.
"No touching," Avery said with a hum, “Trust me Der it’ll feel better if you wait.”
”…This is unnecessary…”
“Hmm maybe it is…” He grabbed Derlord’s other wrist, hauling both arms up and behind the knight’s back then gathered them into one of his hands, pinning them effortlessly against the small of Derlord’s back. As a result Derlord’s chest was pushed down while Avery simultaneously hauled his arms up behind him. The leverage forced Derlord’s back into a steep, desperate arch, his hips jutting high into the air, presented and vulnerable, “But I know you like it.”
Derlord could have argued, but it was easier to focus instead on the sensation of Avery’s length holding him open.
There were no gaps. No relief. Just the sensation of being completely, utterly plugged and forced to do nothing but feel every inch, as he felt his own arousal flood back into his aching cock.
That was the terrifying difference between a man and a slime, he thought. A man was solid, static. Avery was...a fluid density. Even without thrusting, his dick was an unforgivable thing, a heavy liquid that had moulded perfectly to every ridge and curve of Derlord’s insides, stretching him open with a thoroughness that bordered on violation.
When Avery laughed softly, Derlord remembered that he had forgot to deny the slime’s claim.
Filled with a sudden burst of bravery, he then asked Derlord a question, almost shyly, “Soooo…boyfriend of mine…” It sounded strange, but funnily enough, Derlord could feel his face get impossibly hotter.
”…What do you like about me?” The question itself was even stranger, so awkwardly timed that Derlord ignored it all together, chalking it up to be a hallucination considering… their current position. Surely Avery wasn’t expecting a thought-provoking conversation mid-fucking?
"Ah-Avery," Derlord gasped, his hips twitching violently, trying to grind down against the mattress, trying to find any friction against the weight burying him. The position didn’t allow for it. "M-Move..."
“I’m… I’m still waiting for an answer Der…”
Derlord tried to push back to chase the sensation pooling in his abdomen, just enough to force something, but Avery’s response was immediate. His hands tightened around Derlord wrists, forcing him still.
Still no movement.
“Y-You can’t be serious.”
“It’s just… Is that the only thing you like about me?” Avery asked quietly from behind him, voice mild, almost thoughtful as if he weren’t buried to the hilt inside of him. “The strength thing, I mean.”
Derlord scoffed, shivering underneath Avery’s solid grip on his arms, “You are ask—asking now of all times?”
“You’re the one who said to slow down!” Avery huffed defensively.
“I said, slow down. Not-stop—mmN!-“
Derlord’s retort died in his throat, as Avery shifted slightly by accident, his hips jerking instinctively backwards from the overstimulation of being stretched open. A useless motion that only served to impale him further on the static weight of Avery’s cock. The friction was blinding.
“Still waiting,” Avery prompted softly with a grin.
“F-Fucking…” Derlord swore under his breath as he grit his teeth.
Knowing about Avery’s patience was a lot different from being subjected to it. Derlord had always secretly admired it. The way Avery could wait things out, sit with discomfort despite being so hyperactive, the way he would let moments unfold without forcing them. It was… admirable.
In theory.
In practice…Avery’s patience felt cruel.
Derlord’s jaw clenched. “I hate you.”
Avery only smiled wider. “Aw, Der. Don’t be like that. I’m just curious… Do you want to stop?”
“—Y-Your!…Your kindness.”
“My kindness?” He murmured happily with a breathless laugh, “You think that I’m kind?”
Derlord’s jaw clenched, “In an annoying way. Not in a… performative way or a way that benefits you—Nngh!-“
He was cut off by a low moan that ripped out of him as Avery shifted his weight further. Not a thrust, just a heavy, downward press of his hips. The movement forced Avery deeper, the flared head of his cock pressing relentlessly against the swollen, oversensitive gland of Derlord’s prostate and just resting there. He started a punishing pace, each drawn out roll of his hips lighting up Derlord’s nerves.
“Interesting,” Avery murmured, blush creeping further down his neck, “Keep going Der.”
Derlord let out a shaky laugh, “Fuck—ngh— you.”
“Wow. Rude,” Avery chuckled, leaning down to bite gently at the sensitive junction of Derlord’s neck and shoulder.
Avery stopped once more. Derlord was going to strangle him after this was all over.
“You need to learn how to apologise…”
Derlord instantly went still. His composure was beginning to fail as he stared down at the sheets and pinned them in place with a trembling glare. Clarity hit him as he suddenly felt humiliated by how badly he needed the motion back.
“You have to be joking…”
Silence stretched. Avery waited. He was, as Derlord had feared, infinitely patient.
Fuck his life.
“…I apologise.” he ground out.
Avery tilted his head, Derlord could hear the smirk in his voice. “Didn’t quite catch that.”
Derlord’s fists clenched. “…I’m sorry…Avery,” he repeated quietly as he forced the words out.
“It… it won’t happen again.”
Derlord couldn't see it, but he could feel an infuriating smile against the back of his neck.
“That’s better… Good boy.”
Avery’s other hand slid down Derlord’s spine in reward as he leaned back, settling it firmly on the small of the knight’s back. He pressed down.
The angle shifted and so did the pressure on Derlord’s prostate. It doubled.
Derlord’s breath left him in a silent rush. He felt tears prick at the corners of his eyes from the sheer overwhelming muchness of it. He was impaled, pinned, and helpless. To make matters worse, he couldn’t feel his own ass pulsating around Avery’s dick with wet clenches that went unanswered.
“So I’m kind…” he said warmly. “What else?”
Maybe kind wasn’t fitting. Evil and sadistic felt correct.
“…Y-Your Ha—patience.” He could only frown at his own admission. Even now, being taunted and held hostage by that very same patience, Derlord still appreciated it immensely.
“You listen. You do not flinch or shout when I am… sharp.” Derlord paused with a frustrated huff, but continued nonetheless, “You assume I will—c-come around instead of demanding that I change.“
Avery resumed, slower now as a reward, savoring the way Derlord melted at the mercy.
“Haa—…This is- ngHh!-…unfair…”
“What is?” Avery hummed, clearly already too pleased and clearly already aware of what he was doing. He halted to a stop after a few more beats of silence and Derlord groaned in annoyance.
The silence stretched. Avery was still humming a maddeningly smug tune as he settled his weight against Derlord’s back, clearly prepared to wait out the entire afternoon if he had to.
Derlord pressed his face into the mattress, cheeks burning hot. He was trapped. He was humiliated. And worst of all, he was still agonisingly, desperately hard.
Derlord let out a frustrated exhale that ruffled the pillowcase. He knew what Avery wanted, even if he knew that Avery himself didn’t know what it was. The specifically humiliating key that would unlock the movement again.
He could be embarrassed later.
Derlord slowly turned his head so that he could look up over his shoulder. He fixed Avery with a glare, purposefully trembling to make himself look more pitiful, although he didn’t really need to pretend that much.
Avery jolted at the sight. Derlord’s face was flushed a blotchy crimson, at the corners of his eyes—unshed tears of frustration. He was furious. Or rather, that was the intention behind his glare.
“Der?—” Avery’s breath hitched, his voice faltering slightly at the intensity of the gaze from behind the visor, “A-Are you okay?”
He most definitely was not okay. In such a position, apparently he wasn’t allowed to make any demands. But that didn’t mean Avery wasn’t immune to… tactics of motivation.
Derlord swallowed hard. His lip trembled. He needed it. And now.
“A-Avery,” Derlord choked out. The words were stiff, dragged out of him by force. “I need… I need you to move. Right now… Avery please?”
Avery’s breath hitched instantaneously.
Derlord glare wavered, dissolving into pure need as Avery remained completely still.
“Fuck I— A-Are you happy?-“ He hissed, voice pitching up into a mortified whine, “I… I can’t take it anymore, it-it hurts.”
Avery had expected a, ‘Move. Now.’ Or his other personal favourite, ‘Fuck off.’
He most definitely hadn’t expected a desperate whimpering ‘please’.
All of Derlord’s embarrassment instantly converted into smug triumph as he watched the core of Avery’s face bubble into a shade of pink.
An undeniable blush.
Derlord let out an unbearably smug noise. Avery almost pushed him away out of spite. That was until Derlord shifted his hips a little, slow and deliberately whiny.
He’d left his pride back at the couch…it could be retrieved later. And like a shark smelling blood, he went in for the kill.
“A-Avery please…fuck me already…until I pass out? I can take it, I’m ready. Haven’t I been good? Please—”
“You!-…Okay,” he said finally, quiet and a little shaky, “Okay. I hear you. I just—wow… Der you…”
Once again, he fell silent.
Infuriated to no end, Derlord had opened his mouth to prompt Avery to finish his sentence, the words instead flew out of his mouth as a broken choked out moan when Avery pressed impossibly close then pulled out just as slowly.
The drag left Derlord breathless. Panic flared through his mind at the sudden emptiness as his ass fluttered weakly around nothing, “Ahh, shit—W-What-“
Avery slammed back in with the force of a meteor.
“—nGhhhfmph!“
The scream was muffled into the mattress as his head jerked forward, but the pleasure was absolute. The friction finally hit the itch inside of him as Avery abandoned patience entirely and started a punishing rhythm. He used the leverage of Derlord’s pinned arms to control the angle perfectly, driving deep and hitting the exact same sensitive spot over and over again. Derlord couldn't scramble away, he couldn't close his legs. He could only take it. Fucking finally!
"Ah-Avery—slow—wait!" Derlord gasped, his hips twitching helplessly from the overstimulation as he was pounded into like there was no tomorrow. He cursed when Avery actually slowed down a little.
“S-Shit shit shit fuckkkk nmghHh!—no-no,ah- don’t, ah, stop-“
Avery let out a broken chuckle at that then picked up the pace quickly, the wet, slapping sound of their bodies filling the room. The friction built rapidly giving Derlord no time to acclimate, forcing embarrassingly wanton ‘ah’s and ‘mphs’ from his throat. Derlord hadn’t even registered that the moans were coming from him, but once he did, he slammed his face into the pillows, biting down on the fabric to smother the wrecked, sobbing noises.
Avery felt the vibration of the muffled screams against his chest and frowned.
"D-ah-Der don’t hide," Avery reached forward with a shuddering breath, his other hand still secured firmly around Derlord’s arms, “I want to hear you.“
His free hand settled at the red tufts of hair of the crista on top of the helmet. With a sharp, demanding tug, he yanked Derlord’s head back and up. Derlord gasped, his neck and back arched painfully as his face was pulled away from the safety of the mattress. He was suspended completely by Avery strength and cock drilling into him from behind, his mouth open and exposed to the air.
“"Let... h-hah... let go nGh!—" Derlord tried to snap, but the words fractured.
“Der-hey no, don’t be embarrassed,” He used the grip on the helmet to hold Derlord steady as he drove forward, abandoning all rhythm for pure need, “You-… You sound incredible-ha…so sweet—“
The new angle allowed him to bottom out completely with every thrust, the heavy slime adapting perfectly to Derlord’s interior, stretching him to a terrifying fullness. Derlord couldn't fight it. Robbed of any form of cover, held up by his only means of defence, the sounds spilled out of the visor.
"A-Avery—fuck!—wait—uhh!"
Every thrust knocked the breath out of him as his dick bounced against his own abdomen, amplifying the pain and the pleasure until he couldn't tell them apart.
"Too, ngHh... d-deep... c-can't..." Derlord’s voice was gone. He was drooling behind the helmet, his tongue heavy and useless. "S-st... ah! Don’t sto-mNgahhh-... please!—"
He was incoherent, his eyes rolling back. He couldn't even form sentences, just broken noises that pitched higher with every inch Avery claimed.
"Almost," Avery groaned, his own control shattering as he heard the moans echoing from behind the metal, "That's it, Der—so so good for me-“
Avery slammed into him, tightening his grip on the crest, then used it to pull Derlord back into the thrusts. The depth was absolute. It felt as though Avery bypassed every physical defense Derlord possessed, sliding past the usual friction to hit a spot so deep inside him it felt like he was being touched in the throat.
The sensation was simply too much. Avery wasn't even touching him in the front. He didn't have to.
“NGHh! Fuck!!—“
He came hard, completely untouched for the third time.
Derlord’s body convulsed as the orgasm ripped through him, static exploding behind his eyes. His hips buckled as his cock spilled exhausted ropes of cum whilst Avery fucked him through it, burying himself impossibly deep before following Derlord straight after.
"S-Shit, so tight!-" Avery gasped, his forehead dropping to rest against the back of Derlord’s helmet. "Can’t stop, s-sorry can I- inside—“
Avery’s cum flooded into him. A heavy stream of heat released deep inside the knight, filling the space Derlord didn't even know he had left. The grip on the crest of the helmet vanished. Derlord’s head dropped like a stone, slamming face-first into a damp pillow with a metallic thud. His arms, no longer pinned, flopped uselessly to his sides, fingers twitching faintly against the sheets. He groaned weakly as Avery’s release rolled into him in pulses.
"Sorry, Der... notch, doing so well, thank you-" Avery praised, his voice thick and wrecked with pleasure, riding out the endless waves of his own climax, “S-Shit I’m— Almost done, h-hang in there.”
Derlord couldn't answer. He just lay there, twitching and leaking, completely full of Avery, listening to the praise as he floated. The feeling of being bloated alongside the constant pressure pouring against his prostrate dragged any coherent thought away from his mind. The way his body jolted sporadically out of his control to accommodate the intense pressure building up in his abdomen, was the last thing he felt before the overstimulation sent him under a haze.
Derlord resurfaced slowly, blinking in the light of their shared bathroom. He registered the lapping of water on his skin as he felt soft vibrations of Avery’s humming on his back. A steady pressure moved over his scalp, fingers working slow circles through his hair, just firm enough to ground him.
It was unfamiliar…it felt nice.
“There you are,” Avery murmured above him, voice low and fond. “Welcome back, sleepyhead.”
He made a sound similar to a grunt of approval, the soothing sensations at his scalp reminded him that speaking was optional, so he let his head sink further against Avery’s chest instead of replying.
Avery let out an amused huff at that, “Pfff-Commander Derlord…bested by a head massage and a bath.”
Derlord’s eye cracked open with a twitch. Avery just couldn’t let him have nice things.
Derlord’s hand slid up towards one of the hands massaging his scalp, hesitant and clumsy, until his fingers brushed Avery’s.
“Shut up.” He grasped Avery’s hand firmly and removed it, weaving their fingers together and pulling it into his lap.
Avery’s breath hitched, heat slamming back into his face, “I- I can’t wash your hair very well with one hand Der…”
“You… are complaining?” He loosened his hold on Avery’s hand slightly as if he was going to let go, “Very well—“
Avery’s hand locked up immediately, stoping Derlord from pulling away, “I-I didn’t say I couldn’t do it!”
Derlord hummed this time, unmistakably smug but reciprocated the motion. He brought Avery’s hand up to his lips, almost shyly, and pressed a soft kiss to the back of his palm before pulling it back down to his lap.
“That’s what I thought.”
He heard Avery groan weakly from behind him as he rested his forehead against his shoulder, his free hand snaking around Derlord’s waist, “No fair…you’ve always gotta get the last word in huh...”
“You are still surprised?”
Avery sighed dramatically, then pressed a kiss on the back of Derlord’s neck anyway.
“One day,” he warned fondly, “I will win.”
Derlord smiled to himself, eyes crinkling at the edges slightly.
“Unlikely.”
