    Summary

    Their universe fused just under three years ago, and Red has been his best buddy since then.

    Sans has been learning all he can about music in order to confess to his best friend, Red. Three songs and he can only choose one to choreograph. It wouldn't be so hard if he only knew what kind of music Red was into.

    Sadly, he receives an unfortunate news that would stop his progress entirely.

    Summary

    In a city run by mobsters, violence is a way of life. Most people want to avoid trouble, so they keep their heads down and their noses clean, but not you. Oh no, not you. You just *had* to try to make a difference, and look where it got you; tied up, blindfolded, and waiting on what you were sure would be your doom. Fortunately for you, an unlikely savior comes to your rescue.

    Summary

    Les monstres ne sont pas exactement l'image que les humains s'étaient — pendant si longtemps — faite d'eux. Certains aspects pouvaient se rapprocher de la réalité, comme des dents pointues, des "déformations", des poils, des plumes, et cetera... Mais aucun livre d'histoires pour enfant n'aurait pu prévoir ce... caractère... si typique du peuple en question.

    En effet. Ce n'est pas tous les jours qu'une nouvelle espèce intelligente apparait sur Terre. Et ce n'est pas non plus tous les jours qu'une nouvelle espèce intelligente apparue sur Terre possède une libido si débordante qu'elle se reflète jusqu'à dans leur manière-même de vivre.

    Les humains sont intrigués.

    Et un certain squelette aussi.

    Summary

    All you had ever wanted was to find something like you. A semblance of somewhere you might have belonged long ago. A piece to hold onto that said you weren't just some freak of nature accident, but rather a living relic to be appreciated.

    Never would you have imagined this.

    Monsters. They were going to be part of your life from now on, flooding your senses and bringing you a warmth you had never found amongst humans. Bringing a brightness to your brother you had never seen. You were light like his wings and you both were free to be who you are finally. Even if it was deep underground where you might never see the sun again. But that wouldn't matter to you. It might never again matter. You were going to be happy.
    But of course you didn't know this yet because right now you were falling. Down, down into the earth with what seemed to have no end. Your little brother wrapped tight in your arms. If you couldn't save yourself then maybe you could at least save him.

    You hit the ground.

    Summary

    Attraction is supposed to be the easy part. Love is supposed to be the hard part. But it's the other way around for Sans as he comes to terms with feelings for you he hadn't thought possible. Especially considering he's lacking certain parts.

    Summary

    Sans brushed a phalange across the golden heart, fighting the tears that threatened to take form.

    From the moment they had opened their eyes they’ve had a past life crammed into their skull. They know what they have to do—but how? They’re not strong enough.

    Huh, Sans paused, there's a thought.

    They weren’t going to let that kid ruin it all.

    But it isn’t as simple as that, it never is.

    Summary

    *post-pacifist route* Monsters came to the surface a year ago and with them, magic ability returned to the human race. You had no idea you were a mage until you suddenly found yourself in a top secret government program, training under a very unwilling skeleton mentor named Sans.

    Summary

    Pen Pals used to be such a fun thing to do, the badly handwritten letters, the mystery of who you're writing to, learning about them little by little with each letter. It was something no one bothers to do anymore, except this year. No one knew how to really establish any connection to the new monster above ground. They have a lot of history and customs to catch up on and one thing that catched their eye was that letter sharing tradition. M-university has started a program to get humans and monsters closer than they've ever been before...

    Summary

    You've never had sex with a monster, and you want to know what it's like.

    Your best friend, Sans, has never had sex at all.

    You don't have to be a mathematician to put two and two together.

    Summary

    Sans is in heat. You're in a meeting at work. Looks like he'll just have to take advantage of what little traces of you he can find in the immediate environment to take the edge off until you get home... which doesn't take as long as he thought it was going to take.

    What a mess.

    Summary

    I received a request to do a little something based on this imagine I did awhile ago:

    Shortie (MT Sans)
    - He has no idea what’s happening the first time his soul cycle rolls around, especially because it’s probably, embarrassingly, before he even asks you out. Why the fuck does he feel like running laps around the property? Why the fuck can’t he stop thinking about hugging you and nuzzling into you and the way you smell and how soft and warm you are? He’s so high-strung and pissed off.
    - He can hardly look you in the eyes the next morning because he spent all night jerking off while thinking about you.

    Summary

    Well, you just made the biggest mistake of your life, and you can't take it back. You can't rewind time like Frisk can, and even if you could... that would just be breaching his trust even more than you already have, wouldn't it? You can't take it back.

    So what do you value more: honesty or mercy?

    Dancing and sex. Two things Sans loves to do with you for romance and fun despite the energy output they require.

    Why did it not occur to you sooner that he might enjoy a lap dance?

    Summary

    Sans never thought that he would meet his soulmate. Ever. But he should've known that, if he was ever going to meet her, he would meet her at Grillby's of all places.

    And he should've known that it couldn't just be simple and easy for him.

    He should've known she would be a human... and his bartender's girlfriend.

    Summary

    Thinking about you always brought him comfort, even in the darkest of times. What could be better than that?

    Well... how about acting out some of those more private thoughts?

    Summary

    The heart wants what the heart wants. Apparently, so does the body. It was bound to happen sooner or later. The question is: What will Sans do about it?

    My goal was to make an obligatory 'heat' fic that's as realistic as possible - but let's face it, we can only do so much with magic skeletons. I can't promise perfection, but I can promise meaningful conversation peppered among explicit sex scenes.

    I hope this is as fun to read as it was to write. Enjoy!

    Summary

    The skeleton brothers are getting a new place after living ten years on the surface. You, Undyne, Alphys, and Frisk all agree to help with the move. It’s going to be a long day, full of time to reflect and zero time to relax. But there’s plenty of time to remedy that in the evening.

    I recommend this to anyone that likes slice-of-life, character exploration, and the occasional sex scene (found toward the end). Hope you enjoy!
