Chapter Text
When the sun rises the next day, Mettaton is gone.
This doesn't surprise you in the least. He's quite the busy man, what with gaining international fame and all. You're incredibly grateful for the opportunity you had to meet him. And fuck him.
Boy, what a night...
You stretch, hissing as the burn in your lower half kicks in. Your ass is extremely tender, and you're not sure if you'll be able to walk today. While you don't regret anything you did last night, it has been a long time since you did anything like that, and the adjustment is pretty brutal. Worth it though.
You decide not to move too much for now, opting instead to drift off and enjoy the memories of last night.
***
You open your eyes later that morning and smile at the arm clutching your waist. Peering over your shoulder at the sleepy skeleton spooning you, you're filled with a rush of affection for your new husband, so strong it brings tears to your eyes. You carefully turn over to face him, wincing as the slightest movement causing twinges of pain in your ass. You'll have to do something about that soon, but at this moment, you're busy enjoying the way the light catches on his boney face, relaxed and deceptively innocent.
You lean forward and press a kiss to his teeth, tangling your legs with his and absently noting that you're both still stark naked. His breathing changes as he starts to wake up.
"MMM... METTA..."
You giggle, stroking his collarbone. "He stayed longer in your dreams than in reality, it seems..."
He starts, eyes flying open and gazing around the room before trailing back down to you, a blush spreading across his cheekbones. "AH... ER, GOOD MORNING!"
"Morning, sexybones. Sweet dreams?"
He coughs, embarrassed, and buries his head in the sheets.
You laugh mischeviously. "You can't be embarrassed now. It's not allowed, not after we literally fucked Mettaton, the star of the Underground, last night."
"OH GOD..." His voice, though muffled, is pleading.
"Come on, I want to know what you were dreaming about! It's gotta be good if you're hiding from it."
"I... WASN'T DREAMING." He comes back up to look at you, his blush even stronger. "I SUPPOSE I SHOULD TELL YOU. I WOKE UP WHEN METTATON WAS GETTING TO READY TO LEAVE. HE BECKONED ME OUT OF BED AND MENTIONED THAT YOU HAD GOTTEN A LITTLE MORE ACTION THAN ME LAST NIGHT, AND HE WANTED TO RECTIFY THAT BEFORE HE LEFT."
You cover your mouth, eyes wide with amusement and excitement. "You fucked him when I was sleeping?"
"... Y-YES...?"
"Damn..." You give his shoulder the tiniest shove, grinning madly. "I'm so proud of you! Tell me about it! Every detail. No prude-ing."
"OH DEAR..." He covers his face with his hands, but does as he's asked. "WELL... HE WAS DRESSING, AND I CAME OVER, AND HE KISSED ME."
"Yes?"
"AND I WAS NAKED, AND HE STARTED TOUCHING ME, AND I... TOUCHED HIM... BACK?"
"And?"
Papyrus plays back the events of a few hours ago in his mind, shivering at the delicious lewdness of it all. Mettaton kissing his teeth, his jaw, brushing his fingers over his sensitive ribs and trailing down to his pelvis. Mettaton twirling those beautiful fingers in his semi-solid magic, whispering sweetly in his ear. Forming a pussy again, already dripping and ready, and Mettaton's grin in the dim light of early morning as he presses inside, gasping praise and thanks.
"AND THEN HE F-FUCKED ME AGAINST THE WALL."
You blink at the unexpected F-bomb. Papyrus never swears, so this is strange and slightly exciting. "Say that again?"
He takes a deep breath. "HE FUCKED ME AGAINST THE WALL."
You giggle madly, unable to get over this little development. "Damn, don't let your brother hear you talk like that."
"I WILL NOT LET MY BROTHER HEAR OF ANYTHING THAT HAPPENED LAST NIGHT."
"Good plan." You snuggle against him, sighing contentedly. "Was it good?"
"IT WAS..." He coughs again, but he's smiling shyly. "EXCELLENT. METTATON IS QUITE A GENEROUS LOVER."
"Do I need to worry about you leaving me for this excellent, generous, sexy lover?"
He nuzzles your forehead, tracing the naked skin on your side. "I ALREADY HAVE ONE OF THOSE."
"Aww, babe." You lean up to kiss him again, indulging in a few moments of lazy making out, before you ask your next question. "Do you think... you'd want to do something like this again? I mean I doubt we'd ever find someone else who's as good as Mettaton, but it might be interesting..."
"I DONT KNOW." He looks thoughtful. "MAYBE... WE CAN KEEP OUR EYES OUT. I'M NOT TOTALLY AGAINST IT, IF IT'S WITH THE RIGHT PERSON. OH!" He lights up as he remembers something. "I DON'T KNOW IF THIS MEANS ANYTHING, BUT I SAW METTATON TAKE SOMETHING OUT OF OUR LUGGAGE BEFORE HE LEFT."
"What?" You wrinkle your nose in confusion. "From our luggage? There's nothing there that would interest him, unless he wants to try on my lingerie. Which I wouldn't put past him, by the way. What did it look like?"
"A PIECE OF PAPER, I THINK?"
"Hm. Weird. I'll check it out later. I'm too sore to move right now."
His sockets widen in alarm. "OH NO, WHERE ARE YOU HURT? LET ME HEAL YOU!"
"Can't hurt to try, I guess. It's just my butt. From when you, ah, fucked me in the ass last night."
"I DID THINK THAT WOULD BE A LITTLE UNSANITARY, BUT I DIDN'T KNOW I WOULD HURT YOU!"
You giggle, pushing away from him so you can raise your legs and bare your ass. "It's natural to hurt after, especially if you don't do it very often. That's why I asked for a smaller shape, remember?"
He pulls himself up and sits cross-legged in front of you. Rubbing his hands together, a green glow starts to appear, and he lowers one hand to your asshole. Though you've felt it before, it's still strange to be prodded by his boney phalanges, but not unpleasant. There's a tingling sensation as he gently massages around the sore area, and despite still being tired from last night, you start to get turned on.
"I'M GOING TO NEED TO DO A LITTLE BIT INSIDE JUST IN CASE."
"Ok. Give me your hand."
He does, and you bring it to your mouth. Sucking on the fingers and coating them with a generous amount of saliva, you quickly give them back. "There. That'll be lube enough."
He's staring at you, orange cheeked again. You sent him a cheeky grin. "Oh, you liked that? You dirty skele!"
He chokes, unable to take your teasing, and goes back to his task. Sliding his phalanges gently over your opening, he pushes one inside, stroking the inside of your ass and sending healing magic into the area. It's no longer painful- in fact, it feels incredibly good. You're starting to get wet, and it's only a matter of time until he notices.
And... there it is. He blinks, removes his hands, and smiles down at you. "YOU WERE ENJOYING THAT, I SEE." Then, to your surprise, he leans forward to whisper in your ear. "WHAT A DIRTY HUMAN."
What? How? When did he perfect that sexy, deep tone? You lower your legs, blushing deeply, and stare up at him. "Well? Are you going to take care of your dirty human?"
He doesn't answer. Instead, he dismisses the healing magic and scooches backwards. Still holding your gaze, he leans down to place his mouth over your folds.
Well. This got interesting very quickly.
You gasp as his tongue flashes out to taste your arousal, and his sockets seem to gleam. Without warning, he digs in, drawing out your moans and cries with practiced ease.
Most people still think Papyrus is innocent. Even knowing he has a girlfriend (now wife) they just assume that you baby him just like everyone else. If Sans had any say in it, that would be the truth. But he doesn't, and the fact is that your supposedly innocent skellie is very, very good with his hands and tongue.
He curls that long tongue around your clit and squeezes, while the fingers that were not involved in healing your ass curl inside your pussy, hitting exactly the right spot that make you shout his name.
"God, Papy, fuck yes! Right there, touch me right there, oh fUCK YES!"
Your belly tightens and releases, your orgasm washing over you with bright sparks in your vision. You clutch the sheets, panting and grinning, as Papyrus withdraws and lays down beside you again.
"Is it your turn?" you ask breathlessly, trailing a hand over his ribs.
Unexpectedly, he shakes his head. "I DONT THINK I COULD PULL OUT MY MAGIC IF I TRIED. MAYBE TONIGHT."
"Mm, thoroughly fucked by your favourite robot is a good enough excuse to not be able to get it up in the morning. I forgive you this time."
"THANK YOU. FOR MAKING THAT HAPPEN."
You grin wickedly, stretching out and not feeling sore this time. "Oh, Papyrus. It was definitely my pleasure."
***
Later on, when you've showered and peed and pulled on one of Papyrus's old orange sweaters, you trail over to your luggage to try and figure out what Paps was talking about. Nothing is missing from inside your bags, but as you turn to dismiss the strange event, you realise that the name and address card from your luggage tag has disappeared.
You can't help the gleeful giggle that escapes you. Mettaton has your contact details. Which means he definitely enjoyed himself enough to consider doing it again.
You spend the rest of the day tidying up. There's not a whole lot to have cleaned, since monster jizz evaporates by itself eventually, but as you shake out your sheets, ready to have them replaced by the hotel staff later, fine glitter flies through the air and settles over everything in its path. The strong scent of strawberries wafts along with it, and you sigh. "I could get used to this."
"STRAWBERRY-SCENTED SEX?" Papyrus asks as he comes up and wraps his lanky arms around your waist from behind, his bones still slightly damp from the shower. Hearing those words from him makes you burst into giggles.
You blow sparkles from the sleeves of your sweater, grinning. "Glittery gang-bangs."
"ROOTING THE RECTANGLE."
You snort. "Oh my god, Papyrus. You kiss your brother with that mouth?"
"NO. I ONLY KISS YOU WITH THIS MOUTH." He nibbles on your ear as if to demonstrate, knowing full well that it's a ticklish spot. You shriek as expected, batting him away.
Its late afternoon when you finally leave to see some more of the city. You leave the room neat, but looking like a craft-project threw up on it. It's nothing that a hefty tip left for the cleaner won't clear your conscience of.
***
When you finally get back to America and try to settle back into routine, you do as you both agreed: keep your eyes open for potential additions to your bed. But the standard has been set too high, and eventually, you decide to be content as you are.
Your monster friends are constantly pressing you for honeymoon details. You tell them the touristy things you did, leaving out everything that they actually want to know. They all press for more lurid details. Not directly, but the loaded questions are pretty obvious.
Papyrus can't quite hide his embarrassed excitement, especially when Sans and Undyne demand to be told everything. Sans just wants more things to be angry at you about. Undyne is Undyne, and quite honestly you would consider confiding in her if you know she would be chill about it. Papyrus desperately wants to gloat about your adventures, but it's not something he can expect anyone to understand.
"What happens in Paris stays in Paris," you always reply, grinning devilishly to rub salt in the wound. It's immensely satisfying to see the frustration of the asker, who knows there is a story to be had.
About six months pass before there's any word from Mettaton. Alphys happens to mention that he's coming to her place for some routine maintenance, and your heart skips a beat. You can't stop the flush that overtakes you as memories flood your mind, but Alphys doesn't seem to notice.
A few days later, there's a knock at your door, and there he is, looking surprisingly nervous. You pull him inside and text Papyrus to cancel his plans for the next few days.
Your house sparkles for weeks.
