Post-Pacifist life for Mettaton appears to be going quite well for the time being. With his stunning new human appearance, an equally handsome boyfriend, and incredible success on the surface it's hard to imagine wanting more... that is until one short man decides to make life a living Hell for him and threatens to cause him to lose it all.
Set after Pacifist route, human!AU, established Papyton with cheating aspects and slower burn Mettasans. No fontcest.
Alternatively; Nothing is more enticing than what you can't have, and for Sans, nothing could be more painfully true than watching his brother dating a man he despised to his very core. But who is to say that the hatred he felt isn't something more?
Also alternatively; Mettaton cheats after some unrelenting teasing on Sans' behalf and they hate themselves all the more for it, while Papyrus is blissfully oblivious.

N/A; Big shoutout to my betas hell, fae and broke for sticking through this with me and throwing back much needed support, ideas and criticism! And of course thank you to the lovely Evelyn who was my partner in crime for the long haul of this work. You are the best Sans and Papyrus rper I could have ever had the absolute pleasure to work with! Thank you for allowing me to post all our hard work and for turning this dream into a semi-reality.
Human versions of these characters were inspired by Todd-Net's renditions of them, we made a little folder we have made specifically for their art we found relevant. Go check them out, give them a watch if you can, their Undertale work is fantastic if you haven't already seen it around. Likewise I have compromised a playlist with quite a few songs that go hand in hand with this story! Many of the songs won't legitimately fall into place until later on, then they will begin to make sense. I'll go ahead and post the links to the Spotify/Youtube playlists and the art by Todd-Net in the reviews section!
Alright, I believe that is it... Sorry for so much spewing of things before we get down to the nitty gritty! I hope you all enjoy it and we will be updating this frequently as we have almost 300k of content to put out for this fic and it's still in progress!
It has been quite some time since the monsters made the move to the human world, and many of said monsters have found their own places to call home nearby, where they were able to find peace and comfort among their own and their new human company. During the monsters' move to collect their past things and relocate to the surface, some of Gaster's previous workings and machines were found. Alongside them were many plans and blueprints of what King Asgore originally had commission him for. Among the dusty old machines was one that had the ability to completely transform monsters into humans. This machine's purpose was a grim one, as it was created for the sole intention of turning monsters into humans in the hopes they would produce human souls which could then be harvested should it somehow become impossible to obtain them from other humans falling. The technology was never completed, but with the help of a local science research group, humans and monsters completed the project and several of the monsters who wished to be tested were successfully transformed from monsters into what would be their human appearance.
After the transition from monster life to human life, many of Frisk's beloved friends chose to stay within the outskirts of a nearby city, where many small suburbs and perfect little houses stood, just as they would in any good ending. At the edge of the suburbs stood a very tall and lovely mansion fit for a king, owned by none other than Mettaton. Mettaton had successfully made his grand debut as a murderous robot turned glamorous star almost seamlessly after successfully testing the monster-to-human machine. He went on to do several different interviews and quickly became a household name throughout much of the human world by collaborating with many human stars and media across all sorts of shows, though he has yet to create his own studio once more.
In another section of the same suburbs, the skeleton brothers, Sans and Papyrus, found a humble place to call their own in a simple apartment building. Sans found a job on his own to pay the rent and costs of living in the space while Papyrus was still trying to find himself a job. Sans had offered to put in a good word for his brother but Paps wanted none of it. Stubborn and refusing to quit, he was going to find a job himself! Now, if only the human world would accept being a very famous royal guardsman as work experience on his resume... Despite the hiccups, the two brothers have managed to stay afloat. They were also among the monsters who tested their long forgotten father's machine, and successfully started their new lives among the humans as humans themselves!
During their time on the surface, Papyrus and Mettaton had begun to see each other quite frequently and were now very much an item. They tried to keep it toned down so Metta would seem open for his fans, but they were still practically inseparable when they were together. One night in particular, Mettaton waltzed into the skelebros' apartment and left with Papyrus without even so much of a nod in Sans' direction. Normally, Mettaton would've given Sans a forewarning about when they were leaving, where they were going, and when they would be back, as he was usually scolded by the smaller former-skeleton after the fact if he did not. Tonight was quite different though, Mettaton had planned to take Papyrus out and on a tour of his brand new studio for shooting his very own TV shows, on the surface! It was such a grand occasion, and Mettaton wanted to keep it a surprise, even to Sans, so that Papyrus could be blown away. Hell, even Mettaton (although he designed it by hand) had not seen the finished studio yet.
Mettaton and Papyrus had a lovely tour around the entire studio twice, and they later had dinner at a nearby restaurant before going home, all the while completely and utterly content. They were quite oblivious to the chaos that would be awaiting them, or at least Mettaton, when they returned Papyrus home. It wasn't until Mettaton was driving his little El Dorado with Papyrus in the passenger's seat nodding off that he realized Sans did not know where they had been. And Papyrus was so tired... it was well past his bedtime. Metta took deep breaths all the way back to the apartment and gently shook his boyfriend awake so that he could bring him up and help set him to bed. When he walked in with Papyrus, the apartment was completely dark and Sans was nowhere in sight. Mettaton helped to support the sleepy Paps' body on their way to his room and laid him to bed so that he could go right to sleep. Sure enough, as soon as his head hit the pillow, Papyrus was out cold. Metta kissed his forehead and then went to leave the room as quietly as he could, shutting the door behind him. He remained vigilant (or paranoid) as he made his way to the door, still looking for any sign of Sans but unable to see in the darkness. Something did not feel right.
After they had left the house, in far too much of a rush, it had taken quite a while for Sans to calm his anger. His hands rotated in tight circles as he paced by the door, peeking out every now and then to see if they were back yet. But soon enough it got dark, and with a sigh the shorter man flopped into an armchair. With a flick of his wrist, he grabbed a discarded mug up off the floor, placing it gently on the table before closing his eyes. His flesh-covered hands moved towards his head to rub at his temples. The feeling of touching skin to skin was still strange for him. It was warm, tingling almost. It felt like his senses were heightened now, but this wasn't the best time to think about it. With a groan, he flopped back against the chair, twisting to face the wall. If he was towards the door, he would have been unable to pull his gaze away from it.
Running his fingers through his short brown hair, Sans prepared to give up and go to bed when the motor of a car sounded. The man froze, his eye would've been glowing if it hadn't been shut tight. Laying his arms at his side, Sans held his breath as the door squeaked open. He didn't dare to open his eyes, sitting as still as he could. He hadn't turned the lights on, so the house was pitch black as they made their way to his brothers bedroom. Still not wanting to breathe, he waited until Pap's door clicked closed to make his move. He could hear Mettaton moving through the house, most likely looking for him. He flicked on the lamp on the table at his side, and with a dramatic flare he spun his chair around to face Mettaton. Sans mismatched gaze narrowed at the sight of the man, his hands raising as he steepled his fingers in front of his face. For a moment he just stared, until finally a wide grin cracked his face. "We need to talk." He said, far too calmly.
Mettaton stopped dead in his tracks when the light clicked on and he spun around to face the smaller man. He held his breath, trying his hardest to gather himself, but feeling as though his heart would beat right out of his chest. The look on Sans features filled him with a, dare he say, dread that practically had his skin crawling and palms sweating. "Hello Sans, I was just looking for you to say the same thing." He spoke after taking a moment to collect himself so that he, too, could seem calm and cool about the situation. Inside his mind however, everything was telling him to run and scream, to be anywhere but there. He knew better than to keep Sans in the dark about where they had gone, but this was the first time he had stepped this far over the boundary of what not to do. The calm attitude of Sans unsettled Metta far more than he would like, and he could only imagine the utter shitstorm he was about to face.
The near-calm voice of Mettaton only made him smile more until his all-too familiar grin crossed his features. He rose to his feet, rocking back on his ankles as he dug his hands deep into his pockets. "How nice of you to invite yourself out. You'd think this old bag of bones would have been in bed, hmm?" Raising an eyebrow, he stood his ground and looked up at the taller man, before winking and tilting his head in the direction of the door. "Lead the way." They couldn't talk here, not where Papyrus could easily wake up and hear them, and there was a lot to talk about, that much was certain. So Sans just stood there, hands inside his pockets, eyes on the man before him. He could wait all night, but let's face it, he was far too lazy for that. With an impatient huff he took two steps towards the door before standing stock still, waiting for MTT to lead him to his car.
Metta glanced in the direction of Papyrus' room before looking back at Sans, still trying desperately to keep his cool. At least his brother had the decency to take this elsewhere so that they didn't startle Paps out of his sleep. MTT fished through his pocket for his keys and headed to the door, opening and pausing only to step aside for Sans. To make it seem as though everything was in fact fine, to hell if he'd lose his touch in his nerves, he made a slight gesture for Sans to go first, clicking the fob to his car, which made the lights flash once and the doors unlock. "I insist." He spoke quietly but his voice had a tiny bit of bite to it. Mettaton was getting a feel for this man's game, and even if he was afraid of the consequences, he was either not going to play it at all, or play it to the point it breaks.
Sans' hands clenched into fists within his pockets, but he remained stone-faced calm. Letting out a low whistle, he stepped out of the house, smirking as the door shut quietly behind them. Peeking up at Mettaton, he stood up on the tips of his toes, letting his breath tickle the taller male's features. "You insist, do you?" He whispered, his voice gruff for only a moment. He pulled back with a chuckle and shrugged his shoulders, skipping down the steps. "You don't have to break my leg for that." Ah, bone puns. Even in human form they never got old and brittle. Oops, was that another one? Laughing to himself, he shuffled down to the car and pulled his left hand from his pocket to open the passenger side door, letting himself in.
Slamming the car door behind him, Sans sunk into the comfortable seats with a sigh. He had to hand it to MTT, this was a damn nice car. Running his fingertips over the dash, he took in in the rustic, leathery smell of it all. He was actually a bit excited to get to ride in it, but the near stoic grin on his face hid that excitement. It might seem like an oxymoron, stoic grin, but his features held the expression so often that it was hardly unexpected. Leaning back, he glanced at the horizon and waited for the larger man to get in the car, taking one last deep breath, to calm his pounding heart. This was becoming all too real now. For so long he had watched Paps and MTT flit around like some sort of happy couple, leaving him behind. For so long it had been just the two of them, Sans and Papyrus, and now there was this big, beefy hunk of a man between them. Sans let none of these thoughts make their way onto his features though, simply waiting for the night to go on.
Mettaton rolled his eyes at Sans' bone pun, feeling maybe the man should try to expand his vocabulary of comedy through the use of human puns now considering he was one. It certainly wouldn't hurt seeing as he has tapped the reservoir of new skeleton material bone dry by now, pun definitely intended. He headed to the car and visibly flinched as Sans slammed the door. "Even if it may seem I am too rich to care, please, don't slam her doors." Mettaton grumbled as he gingerly got into the car and started it up so they could get going. As he backed out of the parking spot, he asked "Where to? I am not actually planning to stop anywhere, I would just like to know how far to drive to replicate how long this will last." Mettaton said as he began to drive, a bored and slightly annoyed look on his face. The nonchalant grin on Sans face was a facade that began to grow old and MTT could not help but be a little daring to test that. "Keep in mind we are both human now, darling, and I've heard car accidents can be fatal. I wouldn't want to hurt this beautiful car either."
Now it was Sans' turn to roll his eyes, turning to look out the window as they drove along. Flipping his head backwards a bit, he let his unkempt hair flop down as he looked at MTT upside down. "However long it takes to get some answers, of course." He said, completely ignoring the ginger touch he gave his car. He even went as far to call it a 'her', which made him want to gag. It was a car after all. His grin did fade at Mettaton's comment about the possibility of a car accident, but his face was back up quickly and peering at the opposite side of the road as they drove. Not that fast either, in fact he was pretty sure they were just tapping the speed limit. Holding back a groan, he licked his now dry lips.
Sans' nostrils flared as he sat back in his seat, that his as wide and toothy as ever as he looked straight ahead. "Did you know I kept my powers when I became human?" The man asked, casually raising his left hand to inspect his nails. Flexing each of his fingers, his blue eye glancing at MTT in his periphery. He might have lazy bones, but that didn't mean he couldn't outlast his opponent. Starting on an off topic would help, eh?
Mettaton kept driving, trying to pretend he wasn't entirely listening, but inside he was set in panic mode. No wonder the fear he felt was that damn strong. Metta didn't want to believe Sans' words, hell, maybe the guy was just bluffing, but deep in his soul it felt like it was true. He spoke up after another long pause, finally, as if he hadn't missed a beat but was simply paused all together until that moment. "I didn't know that actually." He spoke matter of factly as if the words held no meaning to him, but he knew damn well it meant infinitely more than he let on. He continued at a steady speed, preparing to just keep driving for a while. Sans was most likely not going to just let this slip past him, and as much as MTT wanted to believe otherwise, the smaller man most likely had him right where he wanted him. How was he always one step ahead? "I can explain exactly what we did this evening." Mettaton spoke before glancing at Sans from the corner of his eye then back to the road. Anything to just get this over with, get out of Sans' power and move on.
Sans' smile morphed into more of a cocky smirk as he dropped a hand on his lap, letting it slap on his thigh with a loud clap. He moved on quickly to say that he could explain, his eyes narrowing ever so slightly. "You can, can you? You can explain exactly why my brother was out far past his bedtime? And why you left without so much as a word to me about where you were?" He asked, a sickly sweet tone to his voice. And then, without a moment's hesitation, his blue eye flashed yellow and suddenly the smaller man was no longer in the car. In fact, he was a few feet in front the car, and directly in the path of Mettaton's driving, he stood casually with that grin on his face and his hands deep in his pockets again. If MTT didn't stop in time, Sans knew he could escape. But Mettaton needed to see just exactly who was in charge of this conversation, and it sure as hell wasn't him.
Mettaton's heart practically stopped and jumped into his throat as he slammed on the brakes as fast as he possibly could, the car screeching and swerving to a halt just a mere foot in front of the dude. Metta was clearly shook and took a moment to feel if he was still breathing before he brushed his hair from his face to see if Sans was there and if he was okay. If he wasn't scared now, he felt as though he were just a ghost all over again, like he had left his body and returned just from how terrifying the ordeal was. His foot was still slammed onto the brake, holding it completely still for fear letting off of it even slightly would make it go a million miles an hour. The smell of the burned tires on asphalt was all that filled his mind. Sans sure did have his powers still. Mettaton could be sure of that.
With his eye still flashing he stood perfectly still, taking in a deep breath as the car grew closer. Once the screeching stopped, he rose his left foot and gingerly placed it on the front bumper, just enough to lean down and peer at Mettaton through the windshield. Good, he was still alive. His features relaxed, eyes returning back to their normal blue and brown look. With a shrug of his shoulders he bounced off the car, taking his hands out of his pockets to link his his fingers behind his head. Leaning against them, he scoffed slightly as he stood there, not making a move to get back in the car. "Well?" He asked casually, as if nothing had happened. He did ask him a question, after all. And look how nice and patient he was, standing out in the cold night, the moonlight casting an almost eerie glow on him. For a moment, he felt just like his old self. The soft silver glow almost reminded him of his skinless self. Flashing that classic grin, he just... waited.
Mettaton remained staring forward, almost blankly, his hands wrapped firmly to the steering wheel and revealing a grip so tight his knuckles were white. His foot was still stationed heavily at the stop, and he tried to regain more feeling. He shut his eyes firmly and he finally spoke "Are you okay?" Mettaton asked Sans, not out of emotionally or anything else but out of legitimate fear for Sans' life itself. To hell if he was in trouble already with this asshole, he did not want actual harm to come of him. How... how in the hell would he explain it to Papyrus if he... if he had hit Sans. His body began to shake as an overwhelming feeling of legitimate guilt fell over him. No more messing around and playing games. He wasn't going to play. "Sans please just get in the car. I'm going to find a place to pull over. Please be okay. Please." Mettaton spoke but didn't make any move to open his eyes or let up off of the brakes. He was overridden with his fear, worry, guilt and shame and he laid it bare for once, no longer trying to act calm. He was too scared shitless to hide anything now. He had to just finish this.
He stood there and kept grinning, but then he noticed something was wrong. His gaze moved to his pale knuckles, the fact that the man's eyes were firmly squeezed shut. His smile faltered, and when he spoke he damn near broke his heart. His whole facade dropped, worry entering his blue and brown gaze. As upset over this as he was, Sans didn't realize just how badly shook up Mettaton was. Sighing, he stepped over to the passenger door and popped it open. "Hey, hey I'm fine. It's okay. I'm..." the short man paused, rubbing his hand on the back of his head. "I'm sorry man." He muttered, bending at the waist to climb back into the car. He clicked in his seatbelt, gently shutting the car door this time. Twisting, he looked at the taller man with a grimace on his face. He could take things too far sometimes, and there were no convenient shaped lamps on some random road.
Mettaton slowly loosened his grip on the wheel and opened his eyes when he heard the door shut beside him. He then finally took a deep breath and started to lighten up on the brakes until he cruised along just a little bit further up the road before pulling over to the side and sticking the car in park. "I'm sorry, too. I didn't actually mean anything by my threat, Sans. I couldn't live with myself if I killed you. What... what would I tell Papyrus?" He asked, his voice so quiet and broken it was as if it were coming from his cousin and not himself. He finally looked at Sans, his neutral grey eyes meeting his mismatched blue and brown ones. "I knew how much Papyrus wanted to see my new studio when I had it ready. I designed it myself but I physically didn't see it until this evening, with Papyrus. I thought it would be a nice surprise to bring him on a personal tour of it, something exciting for both of us..." Mettaton trailed off, a smile gracing his face as he felt his cheeks warm up. He looked away from Sans and rubbed a hand on his face then through his hair before taking a deep breath again. "I just wish... you trusted me more. I'd never do anything to harm him. I... I love him." He confided quietly, refusing to look back in the direction of the smaller man.
The more the man spoke, the more silent Sans became. Yes, Paps. Who couldn't love him, honestly? The big oaf was a even bigger dork, him and his puzzles that he loved so much. Frowning, he rose his right index finger and casually slid the door lock up and down while he blew out a sigh. It wasn't that he didn't trust him per say... okay maybe that was lying but deep down, Sans was jealous. He didn't have anyone besides his brother, and seeing their affection made him want the same thing as well. Peeking over at MTT out of the corner of his eye, he moved his left hand towards the driver's leg. Sans reached out as if he was going to pat his thigh, but hesitated. His fingers pulled back until he dropped both in his lap, abandoning his task at playing with the lock and just sat there. Pushing his long tuft hair out of his face, he glanced outside for a moment more. "I can see that." He said softly, perhaps with a little more emotion than he intended. "I'm glad you guys had fun. I uh, I need to stretch out these old bones." Turning to wink at the man, he stepped out of the car and crunched a few steps into the gravel. What did he expect to happen tonight? "Just, no more late nights. We know how Paps gets with little sleep." Chuckling, with that big grin like nothing was wrong, he walked into the woods.
Mettaton watched Sans disappear off into the woods and turned off the car, figuring the dude would return shortly. Maybe he was also a bit shook from the near-death experience as well, even if his teleportation was in effect. Metta sighed and relaxed more in the driver's seat, his head rested back against the leather. He glanced up at the stars, the real deal for once, and truly wondered how Sans could have had such a change in heart. He just... dropped the fight almost completely and sounded almost, somber. It was off putting. What was wrong? Surely it must be something deeper than keeping Papyrus out past curfew. Was Sans... jealous somehow? Protective certainly but jealousy could be playing a factor too. Metta crossed his arms over his chest and tried to clear his mind of it, he was just glad the ordeal was somewhat over. Maybe. Then again, it could just be another ploy for Mettaton to let his guard down further. He shut his eyes again and his eyebrows knit together. How could he have been so foolish and vulnerable in front of Sans, honestly? He still wasn't convinced the guy trusted him, why should he return the favor? He practically just admitted to him he flat out loved his brother. Ugh. He moved his hands up to rub his face as he sat upright more again. If only he had let Sans know ahead of time this all could have been avoided. He just wanted to end tonight on a good note. As soon as Sans comes back they can just head home and pretend this never happened.
He scuffed his feet against the forest floor, blowing out a puff of air. Damn, for having more... stuff on he sure felt colder that he ever had. He was about to just head home, he could get there quite quickly, but the short man froze. Looking up at the stars, he smirked a bit. Who was to say he couldn't tease, not even a little bit? Grinning a little bit, he glanced back at the shadowed form of the car. He still had his powers in this body, but maybe if he miscalculated...
With a puff of air he was back in the car, but instead of in the passenger seat he was on his hands and knees over Mettaton's lap. Looking up with that toothy grin of his, he shrugged his shoulders as he shifted his hands to either side of the head rest. "Oops, misshot I guess." Sans only had to whisper, hovering just inches over MTT's warm body. His own felt flush at the contact, his mismatched gaze narrowing ever so slightly. Was this a challenge? Maybe. But he had no intentions of moving any time soon.
Mettaton looked back from under his hands to be face to face with Sans. He practically jumped out of his skin again but didn't make any move to advance or push him away. His grey eyes narrowed as he stared into the other's face, studying it for any clue as to why he was doing this. "Funny, I never knew you could mess up the aim of your teleportation." Mettaton spoke, having expected Sans to already be in the other seat, but instead he was made painfully aware Sans wasn't moving anywhere by the shift of his hands. What the hell was his game? Whatever it was, Mettaton supposed he was just along for the ride, wanting to see who would bend first: Sans to shift off of him or Mettaton to shove him off himself. What an odd competition. Maybe everything was all just a ruse for Sans to play more mind games like this.
The shorter man simply winked playfully, the tip of his tongue sticking out from between his teeth. "Well you know, new body and all. Getting used to this whole skin thing. I'm going to have to switch out my bone-tastic jokes for something meatier." Sans said softly. Shifting so that his knees hugged MTT's legs, he moved forward so that his forehead was just hardly touching the taller man's. "It's all so new and... warm." Exhaling sharply, he inched closer, eyes locking with his silver gaze. But at the last moment he sat up, pulling up until his lower back hit the steering wheel. Glancing over his shoulder at it, he just dismissed the pressure to look back at the very much trapped human below him.
Mettaton felt himself snap back to reality after the intense pull he felt from Sans who was practically sitting on his lap. He inhaled sharply as if he hadn't taken a breath that entire time and he ran a hand through his hair, trying to make sense of his thoughts. What the hell was that? What the hell is on Sans mind? Is he absolutely insane? And why was Mettaton's body reacting so... odd. His heart felt stopped and hyperactive all at the same time and he still felt like he was gasping for breath. And his face felt so very hot with the cold air around them practically biting it. Part of him almost longed to have the smaller man closer to him just to fend off that cold feeling that was so intense. And yet, he was still trapped under him. He looked at Sans, clearly waiting on an answer and trying to look stern and in control despite how he was being stirred on the inside.
However Sans wasn't a fool, he could feel the increase of body heat all around them. The windows at their side started to fog, and he glanced around it with a chuckle. "Yes... skin is oddly... delicate." Sans mused, pressing his hand against the cold window before quickly placing his chilled hand on the base of Mettaton's neck. He hummed as the heat of him chased away the cold, ever so slowly dipping down until his nose ran across the left lobe of the man trapped under him. Inhaling softly, he took in the musky scent of him. There was something else he couldn't place, maybe a cologne of some kind. "So sensitive and soft." He added, his left hand coming up as he ever so softly ran his fingers tips across his angled cheekbones. Sans didn't pull away this time, but he drew back just enough to capture the gaze that was surely on him. With a soft, airy chuckle he lingered there, almost daring to be stopped.
Metta's mind was once again lost and he had all but forgotten his personal vendetta and why he was trying to keep it cool from the start. All he knew was he had someone warm on him that kept the cold air from biting his face and his cheeks. He relaxed a touch more on the seat and shut his eyes as Sans placed his cold hand from the window against his neck. As if welcoming the touch, he tilted his head ever so slightly back, almost inviting Sans closer anyways. The sound of Sans' voice so close to his ear sent shivers up his spine and the heat began to gather in another area that was almost foreign to him. When he felt Sans' fingertips dance across his cheeks his eyes opened and he stared intensely at the bicolored eyes staring back at him. He moved one hand up and rest it against the back of Sans' hand, a silent plea for him not to stop, but for him to proceed with caution. The pause was bringing him back and he was realizing the gravity of the situation.
Sans' eyes grew a fraction wide as their hands collided, a shuddering breath the first hint that he was losing control. His heart pounded in his chest as heat twisted around them like a blanket, making the rest of the world fade away. He couldn't hear anything else except for their breathing, his own a bit more shallow than usual. Sans tore his gaze away from Metta's eyes, dragging them down to those inviting lips. Carefully sliding his left hand out from under his, he trailed a single finger down the crook of his neck, hooking his fingers sharply around his collarbone. Leaning even closer he gently drug his lips across Mettaton's. It wasn't a full kiss, just a whisper of their lips pressing together. As badly as he wanted this, he kept thinking of what Papy would do if he heard. If. That one word brought him comfort... for now.
With a gentle groan, Sans wiggled his legs down slightly until he was more flush with the larger man. His jeans pulled at his skin, less and less room as things started to get... more blood flow. Huffing he ran the tip of his nose across MTT's jaw line, parting his jaws to nip at his sensitive lope. Yes, skin was a lot more fun.
Mettaton moved his hand that was previously touching Sans hand up to the side of his face as he felt their lips just barely touch. He truly wanted to press his lips flush to Sans but he couldn't bring himself to close the rest of the gap. And his mind began to wander somewhere else as something else started to make itself known. He felt Sans shift down to be even closer and inhaled sharply at feeling him brush against his junk. Whether or not Sans had meant to didn't quite matter, either way, it felt damn good. He let out a soft groan as he felt Sans nip at the soft flesh of his neck and he moved his other hand behind Sans, gripping him and trying to pull him closer against him. His other hand that was at the side of Sans' face shifted to the back of his head and pulled it against him gently, all the while Metta tilted his head back to give Sans better access. It all just felt to good, and he decided that he'd proceed only if Sans would, and the man didn't show any signs he would stop. He knew it would absolutely break Papyrus' heart if he found out but... just one time couldn't hurt. Mettaton had always been so careful around them both. He hadn't even gotten this far with Papyrus yet, and yet here was his brother who was usually the one giving the former robot such a hard time for even a simple peck on Papyrus' cheek. It felt so ass backwards. Was Sans trying to make a point? Was he... Mettaton gave up on finishing coherent thoughts as he pressed himself to Sans, giving in completely. To hell with fighting if this felt so much better.
It threw off Sans only a fraction when Mettaton opened himself more. With his hand on the back of his head he inhaled sharply, digging his round face into the crook of his neck. He left a furious trail of nips across the skin there, his hips rocking ever so slightly to push up against him. Sans' own bulge grazed against his, a sharper groan nearly lost against his neck. One hand gripped the back of the headrest while his other left phantom trails down Metta's side, cupping the curve of his hip. Just as he rocked back to finally lock their lips together, his left ass cheek hit the horn.
Sans jumped, nearly jarring Metta right in the balls. Pulling back sharply, he panted, his cheeks flushed from all the action. Looking down at the bigger man, everything came tumbling back in. His brother... this would kill him. His sharp intake of breath had nothing to do with being turned on anymore as he carefully picked himself off of Mettaton. He hesitated, wanting so much to taste him, but he knew he couldn't. Not to Papy. Licking his suddenly dry lips, he took a few deep breaths to calm himself. He just sat there in stunned silence, too shocked to do much of anything. As much as he just wanted to teleport away, his body felt like stone. What the hell just happened? Sans had wanted to react on the few inklings of feelings he had had, on the sense of being alone and watching his brother with the man at his side. And then he had gone and done this. Closing his eyes he leaned forward until his forehead gently collided with the dashboard.
Mettaton came back from the honk of the car's horn and took a few moments to gather himself and calm the hell down. He moved a hand up to hide his face, everything feeling way too hot now for his liking, but nowhere near hot enough. His face was completely flushed and despite the pain in his upper thigh from a near miss of ball shattering, he was still painfully aware of the bulge making his pants feel ten times smaller than they were before. His heart calmed enough to the point he'd be able to drive so he sat up more and rubbed the back of his neck, not even glancing Sans' way. "Back home?" The taller of the two offered as he got ready to turn the ignition. His voice was practically wrecked, gravelly and dirtier than it normally is, almost as unfiltered as the apparent erection pressing against his pants. As hard as it was, he had to bring them both back to normalcy. This was nothing. Just a... reaction from a near death experience surely. Humans tend to latch to each other if they both experience something traumatizing right? This was just a natural human response. Surely. Nothing would come of it, Mettaton thought as his internal monologue ran. He had his boyfriend, Papyrus. Surely... surely maybe he could soon teach him what he just learnt. Yeah. If that felt so good, it would be bound to do something for him. See? Now it is a learning experience too. A learning experience that will never be addressed again. Mettaton was so wrapped in his thoughts and the feeling in his groin that he had forgotten he was awaiting an answer from Sans.
The cool leather dash was of little comfort to his overheating body. His breath was still unsteady, and Sans fought to control it all. He didn't look up when Metta asked him if they should go back home, nodding where his head was resting. A quick glance at the other man let him know that he wasn't looking his way, so with a sigh he rose back up and leaned heavily into his seat. "Yeah um... take the long way." He said softly, looking down at the very noticeable growth in his pants. He couldn't walk into the house like that, not on the chance that his brother had woken up. Refusing to look over again, he drummed his fingers gently on the side of his seat. He may have been pushing for this to happen, but he wasn't quite expecting the chance of MTT being into it. Swallowing firmly, Sans looked straight ahead as he waited to get this night over with. With his cheeks still flushed and his body still far too warm, he rolled down the window just enough to hang his head out of it. The brisk air felt nice, and he needed to calm down anyways.
As soon as Sans had said the words, Mettaton started up the car and shifted it back onto the road so that they could start the way home. The slippery metal of the steering wheel was a bit hard for him to grip on from how much his palms were now sweating, and in an attempt to calm himself and dry them he took turns rubbing off the sweat to his jeans. He bit his lip as part of him just wanted to rub his hands closer to his own crotch to relieve the feeling there instead of fighting it the old fashioned way of ignoring it. His hands met a state they were fine to drive and he picked up the speed, completely centered on the road and trying to let his thoughts be left in the dust behind his cars twin bullet tail lights. He just hoped poor Papyrus was asleep still not to notice either of them were gone. The boy needed his sleep, Metta thought endearingly as he rested back in the seat. The thought of Papyrus, just contently fast asleep as he had left him made him feel calmer already. Heck, maybe some of his own lip gloss left a little mark. A small smile graced Mettas lips as he kept driving before his eyes widened and he looked at Sans. "Sans, wipe your lips." He all but demanded. If even one little trace of him was on Sans, he felt he'd all but die if Papyrus saw.
Sans was so focused on the road ahead of them that he jumped slightly when Mettaton spoke. Wipe his lips? Blinking, he pulled down the visor and flipped open the lid, seeing a shimmer on his lips that wasn't there before. Despite himself, the short man smirked. "Lip gloss, really MTT?" He asked with a breathless laugh, wiping his lips across the sleeve of his hoodie. The pressure of his own arm against his still sensitive flesh nearly made him quiver, his body begging for release after all that heat.
Putting the visor back in place, the man glanced at the dark houses as they neared their building. When he glanced at their apartment, he startled when he saw a light was on. Shit. Shit shit shit. His hand flew over to Metta's closer thigh without thinking, squeezing it tightly. "Look." He growled, a warning as he tipped his nose towards the shuttered window. If Paps was up... Peeking down at his own pants he saw that he wasn't quite calm enough to go inside yet, but his brother probably heard them pull up. Fuck. What were they going to do now? In alarm he looked at Metta's gray gaze, his own wide in shock. He needed a cold shower, but there was no way of squeezing passed his brother at this point. Letting out a gentle groan he pulled back and flopped against the seat, watching to see if the shutters would move.
Sans took a deep breath, trying to think of something to get himself back to normal. It was hard though, the lingering lust scent around him not helping in the least. While his window was still down, the crisp night air wasn't enough to cool his bones. One bone in particular. Daring to look around, he could climb out the fire exit in the back and let himself into his room, but if he was caught sneaking in... He was damned either way, the thought of hiding and being sneaky only managed to excite him more. He hoped that the ex-robot had some ideas because he was running dry.
Mettaton bit his lip at feeling Sans grab his thigh and squeeze it, giving him a sharp look and erasing the relaxed state he was in previously. Rigid as a rock, Mettaton turned into the parking lot and took a nearby spot to their apartment. He ran a hand through his hair and let out a sigh, there was no denying he couldn't get away with this, Papyrus was awake, it was just a matter of how they could proceed. "Can you use your teleportation?" The former robot asked the former skeleton sat beside him, looking over at him again to make sure he didn't spot anything else on him that could get him caught. All there really was left, from what Mettaton could tell, was the tent he was sporting in his pants. Metta looked back at Sans' face to make sure he wasn't staring for too long, his own face flushing a bit at knowing he had left this effect on him.
His heart beat in his chest slightly at the sharp look Metta gave him, feeling his eyes on his very prominent boner. It took him awhile to find his words, he couldn't choke out anything until his gray gaze met his bi-coloured one. "I could, or..." he whispered, leaning a little bit closer. It was intoxicating to see just how much of an effect he had on this human, so much more evident now that they were human. "Or we could find a quiet spot and just get this over with." There was a dangerous note to his tone, daring the man to keep this going. He could easily just teleport into the bathroom of their house and hop right into the shower, telling Paps that he didn't want to wake him up. The poor boy was too gullible to think he would be lying. But where was the fun in that? His eyes roamed heavily over the others form, lingering on the fact that he was still very much aroused. It would get rid of this for both of them, and MTT had to know that too.
Metta stared into Sans face, studying it as if trying to find out if he had really meant it or not. Was he honestly trying to get them in trouble at this point? "Papyrus is already awake, I don't know if that would be a wise idea." He spoke in a moment of clarity, watching Sans look over his body and taking in the same results that MTT had previously seen from Sans. As much as he was already terrified of getting caught and breaking Papyrus' heart, he truly couldn't help but feel more aroused just thinking about getting this done and over with, without Sans simply teleporting or Mettaton having to drive the way home and sort his issue himself. He looked away from Sans and shut his eyes as he weighed it. "You should just teleport. This should never have happened anyways. Papyrus would be devastated." Mettaton spoke softly, trying to keep his tone more even. "I don't know if you were just joking all this time or if this was something you wanted, but I don't want to hurt him." He said as he opened his eyes to look back at Sans again, his own words calming himself a little as well.
They did nothing to calm the shorter man. There was a new hunger in his eyes, the idea of getting caught by anyone adding more danger to this whole element. Metta's voice may be under control, but he needed to tell the rest of his body. An impish smile crossed his lips as he wiggled closer still, snapping his fingers to lock the car doors. He could honestly leave at any point and time, but that didn't mean that Sans wasn't going to at least try to get what he wanted. While the honest and true thought of breaking his brothers heart made him hesitate, but the pressure down under was enough to chase even that thought away.
Sans hovered an inch or so away from Metta's face, his palms resting on the center console while he kicked his knees up onto the seat. "You know as well as I do the fastest route to calm us both down. In fact it's the most bone-ficial way to see us both out of this." MTT could take that as a boner joke or a literal bone pun, he didn't care either way. Leaning his weight onto his left side, Sans snaked his right hand to Mettaton's belly. Gingerly he flicked up his shirt only an inch, tracing small circles on his skin, just by the hem of his pants. His brown and blue gaze never left his, tongue running slowly across his own lips. There was no denying they both wanted the same thing, but MTT would need a little more convincing.
Mettaton watched as Sans drew closer, and caught the sheer hunger in his eyes, which made him feel even more like he was just under his power. He glanced back as he heard the cars door locks shut them in place and when he turned back, he found he was practically just an inch away from Sans. He looked down as Sans began to trace against his stomach, inhaling sharply the first time his hand was closest to the hem of his pants. He looked back at Sans, his gaze almost like a reflection of how he felt. "We should not." He spoke, trying to stay clear despite the excitement that was pooling under Sans touch. He would have never thought he could leave him feeling this way, but even if Mettaton didn't want to break Papyrus' heart, there was the nagging thought that Papyrus wouldn't be his first if Sans did something with him on a whim that didn't even mean anything... and he couldn't let that happen. MTT brought his hand to Sans and held it still so he wouldn't trace on his skin anymore, all the while holding his gaze, his silver eyes showing how desperately he wanted this to be, but not under the circumstances.
"Doesn't mean we can't." He whispered, his hand now trapped under the firm grip of Metta. Humming, he wiggled just a touch closer as he exhaled softly, his breath tickling the other's face. He could see the desperation, but under that was that damn lingering hesitation. Sans paused, it wasn't like he was going to force himself on him, that wouldn't be fair. But with a soft glow to his blue eye, he easily pulled off MTT's hand without actually touching it. Now free to move he quickly and all too eagerly traced the shape of his bulging cock through his pants. He groaned in longing, keeping his eyes locked. If he really wanted Sans to go, he only had to tell him to stop. As hungry as he was to taste him, he wasn't a monster... anymore. With his heart racing in his chest he touched his forehead against Metta's gaze trailing down to those shimmering lips of his. Just one word, that was all it would take.
Mettaton restrained from making any noises all this time, studying Sans' eyes as the man moved just a little closer. His eyes widened when he watched Sans' eye glow subtly and felt his hand be moved away from his magic. He was about to tell him to stop but was caught off guard when he let out a soft moan, a result of feeling the hand he once held in place now tracing his erection through his pants. His eyes narrowed as he stared at Sans, his silver pools of irises begging for more. His breath came sharp and uneven, and his heart was racing faster than it had before. There was no denying this was so close to what he wanted, but... He moved his hand to Sans' neck as if drawing him closer, but trailed his hand down to the center of his chest before pushing him away. "Stop. Please, Sans. Not like this." He spoke, his voice practically a moan, but he had to get the point across even if he couldn't get to do so in a steady voice.
It was hard to stop with the sounds he had heard, making him want to move on. His hand came up to his neck, making a shudder pass down his spine. But with the firm push on his chest he paused with a hum, raking his fingers across his junk before withdrawing his hand. Studying the man for a moment longer, he closed the gap between them and roughly pressed his lips against MTT's, crushing them together with force. It only lasted a moment before he chuckled, teleporting out of the car and into his apartment. He looked at himself in the mirror, his cheeks flushed and a more than noticeable boner sticking out. Groaning, he flicked on the shower without moving, twisting his hand as if he was turning the knob.
"SANS? Is that you?" Came Paps call, making him open the door to peek out.
"Yeah bro, just went for a walk and I'm going to shower. Sorry if I woke you." Smiling in his usual fashion, he clicked the door shut and hopped into the shower.
Mettaton, after Sans had left him in such a wrecked state by raking across his junk and jumping him with such a strong kiss, was left sitting in his parked car for another moment, realizing he had the moment as Sans had just left and vanished into thin air. He checked his reflection of his face in the rear view mirror and saw how absolutely wrought with lust he was, and part of it really scared him. Despite how out there he was, he had kept clean as a whistle in all reality despite resolving things himself occasionally. Hell, his robot bodies never even had any sort of sexual organs in them at all. And so, the man staring back at him in the mirror was almost one he didn't even recognize aside from the fact he was human. He looked away and ran his hands through his hair to try to tame it a little more before scratching his head. What the hell was he going to do? He loved Papyrus with all of his heart and he could never hurt him. He wanted him to be his first and nothing would come between that. But Sans... until tonight he had never even given Sans more than a side glance as far as this. He always had Papyrus and his own life to live, he had never known Sans had ever felt this way. Up until he had met Papyrus, he was too self absorbed to care much about anyone else in his life, other than a very few handful of individuals. And even then romance was more of an idea, a fantasy, never something really obtainable or... in this case, physical. It felt so very surreal. His heart longed for Papyrus but Sans has his body begging for something else. Watching the bedroom light from where his car was parked, Mettaton sighed then turned on the car so he could ride off towards his mansion. He just hoped this didn't give Sans any other ideas. It was hard enough as it was tonight, and he still needed to take care of the tent in his pants Sans left him with.
