Work Text:
The sun had long sunk below the horizon, painting the sky in a deep purple. It would have been a great night to lay on the grass and gaze at the stars with a lover, or maybe even to tuck into the couch at home and put on an old cozy movie.
But instead, here Tenna was. Still at the studio, still subjected to the most mind-numbing, mouth-drying paperwork.
It was shit work, forgive his language, but someone had to do it. If he just got it all done, read it all over, he could just send it off to legal in the morning and finally be done with it. Though he loved being able to do the show year after year, this was his least favorite part by a long shot. More than anything, though, being stuck in his office all evening meant no Mettaton.
He had stopped by a few hours earlier to check on him, see when he was coming home. His hair had been mussed and his makeup was smudged from his rehearsal. Covered in a faint sheen of synthetic sweat from the exertion, he had looked stunning. Tenna wanted to take him right then and there. Mettaton had smirked at him, likely able to tell as much by the way his antennas stood up straight at the sight of him alone. His lover had a way of making him lose all sense of his sanity, and Tenna would have it no other way.
He had left him with a kiss and told him he would see him in the morning, wearing a grin that made it seem like that may not be the whole truth. Tenna couldn’t imagine what that was all about, but it was typical of Mettaton to have a few tricks up his sleeve.
As he scanned the dull legal terms on the paper, signed his name here, wrote down some numbers over there, he dreamed of him. His beautiful eyes, the effortless way his jet black hair fell on his shoulders, the gorgeous lines of his smile… Tenna’s mechanical heart soared in his chest. Tomorrow, Tenna would spend the whole day in bed with him, just going over every inch of Mettaton and telling him what he loved about each part most. He would pamper and spoil him beyond his wildest dreams. Or maybe, Mettaton might spoil him as he often enjoyed doing, indulging him in all his favorite old tapes. Either outcome would be bliss after having to read all this coporate junk.
As he continued reading, the words blurred and jumbled before him. Screen dimming, room darkening, his desk suddenly felt like a nice place to rest. Yeah, he’d just take a little break, that’s all…
An indiscernible amount of time later, Tenna woke to a soft knock on the door and a small puddle of drool beneath him. “Come in,” he muttered groggily.
Like an angel or some kind of miracle, Mettaton’s smiling face peered through the crack in the door. He rubbed what would be his eyes, then perked up. “Sweetpea!”
Per usual, he looked criminally good. “Still hard at work, mister?” He sauntered in and leaned in over Tenna’s shoulder. Just the simple touch set Tenna ablaze. “All work and no play…” His hands lingered on the CRT before sitting himself on his desk.
“You didn’t have to come back so late for little ol’ me, Mettaton,” Tenna said, leaning on his hand. “I know, I said I wouldn’t be much longer but—“
“Do you really have to do it all tonight, dear?”
“Well, no, but I figured—“
“It’s no way to spend a Friday night.” A finger played idly with the cup of pens on Tenna’s desk, spinning a marker around the tip of his index. Mettaton had a point. The stack of paperwork was still substantial, but Tenna had made somewhat of a dent. He could theoretically take a break.
Tenna chuckled. “Right, because I’m some party animal?” His finger skimmed the sides of Mettaton’s boot. “I’ll be yours in a moment, let me just finish up this last one and—“
With a devious smirk and a single push of his finger, the cup of pens spilled all over the desk. Markers and writing utensils rolled across the surface and onto the floor unceremoniously.
“Oops.”
Tenna grabbed his hips as Mettaton giggled, sliding him so he sat directly in front of his chair. “You’re ridiculous, you know that right?” He practically pulled Mettaton into his lap, smothering him with kisses. “You’re no better than a cat.”
Mettaton found Tenna’s mouth easily, coaxing him into a lazy, wet kiss. His tongue relished the strawberry sweetness of his lipstick, hungry for more. Tenna hummed as his nimble fingers found the vents on the sides of his casing and gave him a little scratch.
“Hmm,” Mettaton mused, pulling out of the kiss. His lips were wet. “That’s fitting, seeing as you’re my big puppy.”
A whine involuntarily escaped Tenna. His screen flushed pink. Mettaton’s eyelids were low, expression dangerous.
His lover knew the effect that this had on Tenna, all the “good boys” and pet language. He was loyal to Mettaton, so it felt exceptional to be rewarded for that by the person he loved most. It was something special they shared at home, but here? In his place of business, after hours? The scandal of it all only egged Tenna on further. And Mettaton knew this.
Still, Tenna played coy, not wanting the game to end. “How so?”
Mettaton tapped a finger to his chin, pretending to think. “Let’s see…” He reached for the end of Tenna’s tie, twirling it around his hand as he spoke. “You’re very loyal, you’ve got that silly wagging tail, and…” He yanked the tie forward suddenly, bringing Tenna’s ever-reddening face closer. “You whine an awful lot,” he whispered.
Tenna was on the end of Mettaton’s leash, and he could think of no better place to be.
The CRT sprung up from his seat and pushed Mettaton onto the surface of the desk. One of his lover’s plush thighs slotted between Tenna’s, pushing into his hardening cock. It took everything in him not to start humping his leg like a pathetic animal.
“You drive me crazy, honey,” Tenna muttered into Mettaton’s neck fondly as he made quick work of undoing his belt buckle. “What am I gonna do with you?”
“I can think of a few ideas.”
Gloved hands dove past Tenna’s undone fly and groped his erection, causing the man to gasp. His own hands hiked up Mettaton’s legs, spreading him out on the desk before him.
Shamelessly, Mettaton lifted his hips to chase the friction between them. Tenna joined him and rutted against him, lost in the ecstasy. His pants would be ruined unless he got them off soon, but he couldn’t find it in himself to care. Mettaton whimpered underneath him.
Buttons scattered across the floor as he tore Tenna’s shirt open, wasting no time grasping and groping at whatever he could reach. He notably left Tenna’s tie on, which only thrilled him further, imagining what Mettaton’s intentions for that little detail were.
“My big puppy… you just needed some release, didn’t you?” He played with the dials on his chest, each little twist and poke making Tenna whine. Steam puffed out of his vents, internal machinery starting to heat up a dangerous amount.
“Y-yeah,” Tenna whimpered, giving in to his urges and brazenly humping Mettaton, who had started toying with his sensitive antennas.
“You deserve to feel good, darling, and mmh… you feel incredible… Good boy.”
The crashing of their hips, the sound of Mettaton’s voice— it was nearly enough to put Tenna right over the edge. It became apparent how truly pent up he had become when he was this close hardly being properly touched.
As they rocked, Mettaton’s hair flopping back from his face, Tenna caught sight of the god damned paperwork again. A strange feeling of guilt pierced him.
It was just a break, but he was getting carried away. He was gonna explode at any moment and then, what, do more paperwork? He had hardly earned such a reward!
Pesky thoughts entered his brain, as if a little TV-shaped angel on his shoulder was whispering into a mechanical ear. He drew back from Mettaton, catching his breath. He whined at the sudden loss of contact, mouth hung open with dissatisfaction.
“I’m sorry, I should—“
Mettaton glared up at him, cheeks red and sweaty. “Tenna.”
“Knowing me, I won’t wanna do any of it tomorrow—“
“Tennathy.”
“You know that’s not what ‘Tenna’ is short for.”
His lover huffed an annoyed sigh, pouting. Unfortunately, that irresistible expression only made Tenna want to work less.
“You are killing me, pudding. You seriously can’t pull yourself away just for a few minutes?!”
Tenna leaned down slightly to kiss Mettaton’s boot. “I know, doll face. I’ll make it up to you. Tomorrow, I’m all yours.” Another kiss, slow and devotional. “But this is reeeeally important.”
He retracted his boot. “More important than me?” he quirked a brow.
That was a mistake. Tenna bit his lip.
Tenna knew it was all an act on Mettaton’s part, that he wasn’t that insecure. Still, it was clear that Mettaton had come into his office with a singular goal in mind: to get Tenna to chill the hell out. He had just needed some riling up first.
“I didn’t mean it like that—“
“Welly well. I see how it is.” He sat up a little, brushing himself off. “Though, if you’re so married to your work tonight, I may have come up with a compromise.”
Tenna smirked. “Oh you came up with something, just now? No ulterior motives at all?”
The smaller robot snickered as he slipped out of Tenna’s grasp like it was nothing, moving behind him with unnatural speed so his body was flush against Tenna’s backside. Tenna gasped at the unexpected movement and the hand grabbing his ass. It was a reminder of how much bigger Tenna was, the fact that Mettaton was able to sneak around him like nothing. He swallowed.
“Ooh, did you like that sweetheart?” He couldn’t see it, but he could imagine the exact, gleefully evil expression Mettaton was wearing.
He never stopped being bashful when it came to dirty talk, though, opting for just a mhm instead of Yes please Mettaton never stop touching me I’ll do anything you ask me to.
Another hand stretched up Tenna’s back and pushed him down harshly, leaving him face-to-face with the stack of files.
“You’ve been working so hard, puppy. Don’t you think you’ve earned a treat?” His soothing, dulcet voice sifted right through him, making his limbs turn to jelly under his loving touch. And his tail, the damn thing, couldn’t help but wag eagerly at his enticing words.
“Keep doing your important paperwork, then. It’ll be like I’m not even here,” Mettaton drawled from behind him.
Tenna’s heart pounded in anticipation. The words became even more nonsensical than before when all he could focus on was the hard-on in his pants and the faint sounds behind him. Belt buckles jingling and clicking, elements sliding into place…
Realization washed over him. He bit back a smile.
He picked up a loose pen and pretended to care about the paperwork, rereading the same lines over and over again. Mettaton pulled Tenna’s pants and underwear to the floor in a single, coordinated motion. He took his time, running his hands over the swell of Tenna’s ass, feather light touches making the large robot tremble beneath him. After spending all day at work towering over his employees, he loved to feel so vulnerable and small.
Mettaton ran a tongue along one cheek, leaving him with a kiss. A dopey grin stretched across Tenna’s face at the thought of one of his lipstick prints staining him there.
“Oh, sweetness… Let me take care of you.” His lips trailed further inward, nearing Tenna’s hole.
Tenna was “reading” a document, something about funds being allocated to each department for the new season. His grip on the pen was unsteady. When Mettaton’s warm mouth licked at his entrance, he moaned, making his signature scribble across the page at the new touch.
“O-oh! Mettaton!” he whined dumbly. The pleasure was too much, too good as he continued swirling his tongue around his eager hole. He almost wanted to run from the feeling before it all ended too soon, but Mettaton’s strong arms had coiled around his legs. The fact that Mettaton had him just where he wanted him only made Tenna feel even hotter.
His tongue worked him open, taking his time to slick up Tenna. A hand reached to grab Tenna’s cock. When Mettaton finally touched him, running a thumb along his weeping tip, the CRT could no longer pretend to care about anything else.
“P-please, Mettaton…” he whispered into the dark room at the slow stroking of his cock. “Please…” Hoping to sneak a glance at the magic happening behind him, he turned his head as far as he could manage.
“Mmh, what was that?” Mettaton’s mouth was replaced with two fingers, prodding at his hole.
“Please, can you…”
He sunk in deeper and Tenna bit his fist. “Come again?”
“F-fuck me, please, I need you so bad, sweetheart…” He stopped caring about the words he was saying, he knew he meant them wholeheartedly even as his face grew hot and flushed.
Mettaton pulled his fingers out and Tenna clenched at the absence, feeling desperately empty. He tutted. “Oh, but I thought you had work to do?” Tenna loved it when he was petty.
Hopping up onto Tenna’s chair for more leverage, that was when he finally caught glimpse of Mettaton’s grand plan. He had fastened a custom-made, fully-sensitive attachment to his body. Tenna was well acquainted with its weight and stretch, and the memories flooding back to him at just the sight of it were enough to make him drool.
Mettaton giggled. “Well, I suppose you’ve been good enough. Hands on the desk, dear.”
Instantly folding, Tenna set his hands out in front of him.
He felt the tip of Mettaton’s cock tease his entrance. The room was quiet enough he could hear both of their internal motors working a little harder to keep them functioning. It delighted Tenna to know that Mettaton was having just as wonderful a time as he was.
His movements were slow, deliberate. Tenna groaned as he slowly stretched him out. Every sense was on fire, stars forming in his vision as he got deeper. So intense, his mind could only conjure one single word: Mettaton.
He didn’t move upon bottoming out, instead just letting out a long exhale. “You’re so tight, dear.”
Tenna’s heart stuttered.
When Mettaton’s hips finally started rocking, it was as if all Tenna’s prayers were answered. He lost himself in the stretch, in the slow drag of his cock inside him, the pure ecstasy when he’d hit that spot. The small grunts and whimpers coming from his lover’s mouth were quickly becoming his favorite song.
“You feel so good, darling… Doesn’t it feel good to take a break?”
“Mmh, s-so good, oh…” His claws were beginning to carve into the desk, wrinkling all the important paperwork he had been drooling on. He didn’t care.
A hand tugged gently at the collar of Tenna’s necktie. Mettaton grabbed hold and pulled taut, arching Tenna’s back and somehow positioning him even deeper inside. A needy moan tumbled from Tenna’s mouth, but he needed more.
The smaller robot continued thrusting himself inside at a steady, slow pace, delighting at the effect it was having on Tenna. Pathetic moans and whines fell from Tenna’s speakers, unintelligible pleas uttered every time Mettaton pulled all the way out and promptly slammed back in.
“What a good boy you are, Tenna. Taking me so well.”
“Unnhh…” He was putty in Mettaton’s hands. “T-tighter, please…”
Mettaton’s grip on the tie fastened, straining against Tenna’s neck. The pressure was delicious, and only further closed the distance between their bodies.
“F-faster…”
“Awfully demanding tonight, aren’t we Mr. Tenna?” The CRT huffed a shaky laugh in return. “Well, you’re lucky I love you so much.”
Before his heart could properly soar at Mettaton’s words, the smaller robot’s hips were slamming into him at breakneck speed, punching deep guttural sounds from Tenna. Every thrust hit better than the last, but his pace was so great Tenna hardly had the reaction speed to keep up.
“F-fuck, Mettaton!” he exclaimed, claws shredding the paper below. Hopefully that wasn’t too important.
Mettaton let out a dramatic gasp. “My, my! What a potty mouth.” He didn’t relent.
“So good, it’s so good, mmngh…” He was surely talking nonsense now. He was somewhere else, the words coming before he could even process saying them. “You’re perfect, please, t-touch me…”
Wordlessly, Mettaton snaked a free hand to Tenna’s painfully hard cock. The larger robot shivered and bucked into the touch as best as he could, given the leash Mettaton had on him. He stroked at a feverish pace. Tenna clenched around him.
“S-so eager… you’re such a good boy, Tenna,” Mettaton panted from behind. His speakers crackled and whined, fans roaring loudly under his chassis. He was moaning freely now, his hips slamming into Tenna at an uneven pace.
Tenna wailed in ecstasy. “Ahh, ahh, I’m s-so close, I’m not gonna—“
Mettaton was right there with him, grip on his tie tightening ever so slightly. “Me too, love. Let it all go, puppy.”
The loving, ruined tone of Mettaton’s voice was all he needed. As the grip around his cock increased in speed and pressure, strokes matching time with Mettaton’s thrusts, Tenna came undone.
All the tension escaped his body as he came into Mettaton’s fist with a yell, body heaving and shaking as all his pent up stress melted away. As he clenched around Mettaton’s cock, he soon joined him in climax, pumping Tenna full until he had nothing left to give.
He fucked him through it, slowing down as they both reached the limits of their stamina. The tie fell loosely as more air entered his lungs. Tenna felt so comfortably full, not wanting Mettaton to be anywhere else but inside him.
Laying on the desk, he caught his breath as Mettaton fell forward onto the expanse of his back, drawing small, content circles on the soft silicone skin. He pet the top of Tenna’s head softly, minding the sensitive stems of his antennas. “You’re wonderful,” he whispered into his skin.
Mettaton slipped out, leaving Tenna feeling quite empty, but he continued petting him to ease him into the sensation. Some of Mettaton’s release trickled down his leg.
Tenna stayed in place, completely spent and utterly debauched. Mettaton rested atop him, limply clinging to him like some kind of backpack. Their chests rose and fell as one. Their fans whirred in sync.
“You’re… amazing…” Tenna panted, screen smooshed up against the flat surface of the desk. Mettaton rolled off so he could lay next to him.
“You’re not so bad yourself, sweetness.” The smile that spread across Mettaton’s face was as sweet and warm as pie, hopelessly lovestruck.
He always knew what Tenna needed, even if Tenna didn’t know it himself. Just like how Tenna would always be there for Mettaton’s needs, they took care of each other. Tenna had never felt so loved and cherished in his life. The thought used to scare him, but it didn’t anymore. Now, it was the most freeing feeling in the world. To let himself be truly known by another person was the most wonderful thing.
“I love you so much, Mettaton.” He pulled him closer by the chassis into a slow kiss. Nothing more, just deep, passionate, and full of promise.
As they pulled away, Tenna brushed some hair from Mettaton’s eyes. The look returned to him was tender. “I love you too, Tenna.”
That night, Tenna brought the stack of mostly in-tact paperwork back home. Him and Mettaton would sort through it together in the morning, and then it would truly be done, once and for all.
But for now, Tenna would only think about the warm, clean sheets of his bed, the softness of his favorite pillow, and the calm, cool air sifting in from the night sky. He would focus on the comforting, familiar heat of Mettaton’s body wrapped up in his, deep in sleep. He would savor the lingering taste of strawberry lipgloss on his tongue. Tenna pressed his nose into the sweet scent of his lover’s fruity shampoo and drifted into the quiet of sleep.
