HI! I’m Hannah, nice to meet you!
So this is my ever-growing collection of slutty scenes of me shipping the various Sans AUs.

It’s totally 18+, very sexually explicit, and will feature SansxSans and SansxOC ships.
It’s literally smut, it’s in the title.

Please keep in mind, the sexual orientation and even gender of various characters will be either changed, altered, or just ignored for the sake of personal pleasure. It is not meant to insult, belittle or disregard anyone, it is literally just me exploring sexual ideas and scenarios in a safe constructive way.
If that’s something you don’t agree with then I 100% understand and advise that is not the fic for you. 😀

Keep in mind that abusive scenes or scenarios might be in here including Yandere’s, emotional abuse, rough displays of BDSM, and so on.
I will do my best to avoid gore but I can’t guarantee that with AUs like Horrortale.

SansxFrisk, SansXPapyrus, and FriskxChara will not be included. Granted I have no issue with aged-up content or literally anything you choose to write.
Not my circus, not my monkey’s.
BUT just because I’m indifferent to you doing it, doesn’t mean I feel it’s ok for me to do it. I only really do aged-up content for pinups but yeah, none of that here.
THOUGH I will include brothers if it’s both of them going after one person. Like Dream and Nightmare pursuing my OC and then having a threesome.
Anything strictly Dreamare/Fonstcest will be separate from this so you can filter it out with the tagging system. 

So no incest in this but maybe in other stories.

Also furry variations maybe in here too, no Sans will be 100% an animal but they might have stuff like ears, a tail, and the knot/pocket. So think Lamia/ Naga’s, werewolves, furries, bird people.

How this will work is that each 1-3 chapters will be a unique scene or scenario. Some I will just daydream, some I’ll get inspired by a chatbot and others may be sex scenes from my own AU that I didn’t want to put in. Either way, most are like mini AUs focused around sex that I’m too lazy to write a full AU for.
However, if there’s a section you really enjoy and want to hear a full story please leave a comment! I’ll be more than happy to expand these lil saucy samples into a fun smutty story.

Because of this, I will use the notes to credit AUs/characters and any chatbots I used as references. I will also put the theme and what kind of sex at the top in the notes. This way you can skip chapters and just get off to the stuff you enjoy.

Also you do have my permission to take plots, ideas, and scenes and take them and expand upon them. I just ask that if that chapter(s) has a reference please credit them and me.

You can also make fanart, change it up, do whatever.

Go ham. I genuinely don’t care, I’m just here to pop my pearl.

Chapter Text

Error was in the anti-void, knitting diligently, his mind focused on his work. That is until Ink and Blue popped in from a puddle of ink.

Groaning he glanced at Blue who ran happily through the space, leaping onto his beanbag with unbridled enthusiasm. Ink followed behind, happily diving in after him, playing together. Error stood up, scratching his brow he walked to them and leaned over his beanbag.

“Could you guys maybe stop being so loud? I’m trying to do something.” They looked at Error, all smiles.

“Error, why not join us?” 

He rolled his eyes.

“Join you? Humf, I’d rather stay here and knit.” 

Blue glanced at Error shyly.
“I mean can we at least take you to the park? We could see the lake and the ducks.” He gave him a small hopeful smile.

Error stared at Blue which made him blush, Blue couldn’t handle Error’s intense gaze, it made his chest tumble into knots.

Raising his brow he huffed at Blue’s odd reaction while Ink watched on with a mischievous grin.

Standing up sharply, Ink smiled happily “OH MY! I totally forgot I needed to do something! Error could you take Blue home later when he’s ready?”

“OH COMMON! YOU CAN’T BAIL HIM ON ME!” Crossing his arms Error looked at Ink infuriated “He’s your friend, you do it.”

Knocking on his own head Ink played innocent “Oh Error you know how bad my memory is, once I’m gone I’ll probably forget! Not to mention Blue so wanted to hang out with you.”

Looking to Blue, Ink gave a small suggestive wink which made Blue look away embarrassed. Looking from Blue to Ink, Error could tell there was something going on which made him even more frustrated.

“You two are planning something! Tell me what’s going on!”

But Ink just happily made a puddle. “Oh no, I gotta go BYEEEE”. Then he was gone.
They both just looked at the spot in silence, Blue sitting nervously while Error could only eye him suspiciously.

“Well… You got me alone… What do you want?”

Looking up at him sweetly, Blue smiled “I just wanted to spend time with you…”

Rolling his eyes he sat next to him on the beanbag. “Fine, wanna watch Undernovella together?”

Nodding happily Blue beamed at the idea. “Yes! I’d love that.”

Sitting next to each other they silently watched, with Error glancing suspiciously at Blue. Eventually, Error stared a bit too long and quickly diverted his gaze.

Tilting his head Blue scooted a bit closer, “Are you ok? I can leave if I’m making you uncomfortable…”

The look of sweetness and pure worry made Error gulp. His chest tightened and his breath hitched softly at the sight. Turning away he soft said “No… It’s… It’s alright…”

Smiling Blue stayed close to Error but not enough to touch him.

Breathing deeply Error finally spoke. “Blue… Why did you want to hang out?”

Looking a bit nervous Blue blushed “Because I wanted to?”

Raising his brow he could tell Blue was hiding something “Yeah that doesn’t answer the question, you’re acting…Weird…”

Sighing Blue braced himself “I…I like you Error, I like being around you.”

“Well, that’s dumb.”

Blue couldn’t help but giggle at his sharp response.
“Error contrary to popular belief you’re actually a fun person to be around. I genuinely admire you.”

Flushing blue Error had no idea how to respond to that, he just buried his head in his scarf.
The compliments, his gentle smile, it sent his mind reeling. But more than that Error was curious. Looking to Blue Error got in closer, his body trembled but he couldn’t help himself.
Leaning back Blue looked at Error in shock as he crept forward, eventually laying back onto the beanbag enough for Error to be leaning over him breathing deeply.

Blue softly trembled, his small frame was dwarfed by Error who had him effectively pinned.
Though he didn’t stop him, a part of him wanted this. He looked up at Error who stared at him.

“Do you want me Blue?”

Blue nodded.

“Do you want to be with me?”

Blue nodded and with that Error leaned in closer, with a trembling hand softly caressed Blues's face. His soft touch made Blue sigh, leaning into his hand his eyes fluttered shut. His touch made his body burn, longing to feel more of his affection.
“Error…” he gently moaned.

Unable to control himself, Error leaned in slowly and kissed him. The sound of him moaning his name made his heart pound, igniting a passion in him he’d never known.
Softly caressing Blue's sides, the softness of his ecto-body gently quivering to his touch.
“Fuck, you’re so sensitive…”

Gripping the curves of his waist he deepened their kiss, allowing their tongues to fall ino a passionate dance as Blue navigated Error's plethora of tongues. Each desperate to explore his mouth, the feeling making his eyes roll back.

Pulling away Error removed his jacket and sweater, revealing his torso. Leaning forward Blue softly kissed his body. Exploring the dips and curves, each small lick leaving trails of fire across his ectoplasmic skin. Looking up at Error his gaze felt erotic and made Error pant in horrid longing. 

Softly petting Blue’s head he looked at him softly. “Do…Do you want to go further?”

Nodding, Blue softly caressed the aching bulge in his shorts. His girth struggled to break free from its confines, leaving Error moaning.

“Don’t… Don’t tease me…”

Smiling Blue softly pulled down his shorts, his cock was finally free, stood proudly leaving Blue staring at it in awe. 

Blue blushed at its sight. It was bigger than he expected, a whopping 14 inches long and 2 ½ inches wide. Blue gulped, genuinely intimidated by his size but despite the fear he couldn’t help longing to have it fill him. His mind rushed with thoughts of Error dominating him.

Error smiled “Do you like it?”

Nodding, a small smile grew on his face. The thought made him even more hungry for Error as he trailed his tongue over the tip, forcing Error to moan. Then slowly trailing along the shaft as his hand teased the tip moving down to small strokes that made Error almost shatter in his grasp.

Finally, he slid it into his mouth, taking it all the way into the back of his throat, softly gagging as its size strained his jaw. The feeling was nothing like Error had ever felt, it was so good it practically drove him mad with desire. Taking Blue’s head, he thrusted forward, desperate to feel the wet embrace of his throat. Surprised Blue gripped onto him tightly but eventually submitted to it. 

Drool dripped from Blues's mouth as Error continued, lost in the feeling of pleasure as Blue gripped onto his ass, his eyes rolling back to the feeling.

Finally, with a groan of pleasure, Error bucked forward, filling Blue’s mouth with his hot load. 

Squeezing his thighs he swallowed, savoring every drop as Error looked down at him softly stroking his face.

Blue’s tongue lulled out and dripped as Error removed himself. He was on his hands and knees looking up at him, obediently waiting to serve Error with a needy lustful gaze.

Error’s breath hitched at the sight, seeing Blue submit to him made his tender member already hard and throbbing.

It softly dripped with his desire.

“Lay down on your back.”

Obeying him without question Blue laid there vulnerable, his body softly shuttered with anticipation.

Crawling over him, Error undressed him, savoring every soft curve as he slowly exposed him to his hungry gaze. He could feel Blue gently squirm and sigh to his touch, his eyes practically begging to be filled. 

Smiling Error licked down his body, his tongues sweeping over his skin to his awaiting cock. 

Compared to Error’s it was far more average, 8 inches in length and 1 ½ inches in width, it twitched with every lick and touch that set his aching body ablaze. 

He couldn't help but pant as Error got closer, until finally his tongues eagerly wrapped around his shaft, gently stroking him. The feeling made Blue softly shift his hips forward begging for more friction as his body sercume to the unfathomable bliss. 

Gently caressed Error's head, he softly guided him to his weakest spots looking at him with genuine care and admiration.

Grabbing Blue’s hips Error went lower, his tongues teasing the tender skin of his sack and finally to his tight hole. 

Moaning to the feeling, Blue gripped the fabric of the beanbag. Filled with fear and desire Blue gasped as Error teased its rim, demanding entrance to his depths. 

Gasping his body relaxed, spreading his legs fully to allow Error full access. 

Taking advantage he pulled his hips up, letting his tongues worm into his ass, causing Blue's leg to spasm and his toes to curl. 

Once confident Blue could take his monster of a cock, Error softly set him down. Using his cum from early he stroked himself, spreading it like lubricant around his member. Leaning over Blue he positioned himself and gently probed the entrance. 

Grabbing onto Error's arm nervously he watched. Looking down on Blue, Error stopped. 

“Are you ok? We can stop if it's too much. “

Looking away bashfully, he blushed “No, I'm ok. But let's take it slow… “

Nodding Error gently entered him, moaning at the feeling of his tight body wrapped around him.

Gasping, Blue struggled to breathe, his size was overwhelming. The mix of pain and pleasure confused his senses. 

Seeing Blue struggle Error stopped, letting him catch his breath. After a moment to adjust he gave Error a soft nod. With the signal to continue, Error fully sheathed himself inside Blue, both panting and trembling at the mere connection.

Trying not to cum immediately, Error breathed deeply, his cock twitching making Blue softly moan. 

“Error…”  He gasped, looking up at him with his tongue lulled out as he panted.

Being spurred on but his words Error began to move, slowly at first, savoring the feeling of Blue’s tight hole gripping him. He couldn’t help but groan, his body felt so good and he could barely hold himself together.

Looking down at Blue he was shattering beneath him, his moans filled the room as he drooled. His eyes glazed over in pure ecstasy as Error claimed him. Seeing him so fragile in his grasp made him pound him harder, the slapping of flesh could be heard as Blue arched back, sweat dripping down his temple. 

Error smiled, gripping Blue's twitching cock, causing him to jolt forward. “Error…It’s too good… You’ll make me cum…”

Looking down at Blue his grin twisted as he stopped, making Blue whimper in need “No… Why did you stop?”

Leaning down he gripped Blue’s chin forcing him to match his gaze “I wanna hear you beg…Tell me you’re my little slut…”

With ragged breaths Blue stroked himself, spreading his legs. “Please… Please fuck me… Please make me your little slut…” He stroked the tip of his cock, desperate for release looking up at Error, his eyes pleading for his attention. 

Smiling Error moved again softly stroking his face “Good boy…” Taking his shaft in his hand Error stroked him as he thrusted harder.

Then taking his legs together, Error put them to one shoulder and leaned in, his cock reaching into the most tender spots of his ass, causing Blue to scream in pleasure.

“That’s right…Cum for me… Cum for me my lil slut.” Blue panted, his body tensing to his commands. Finally, his cock burst, cumming spurting out onto his stomach.

But Error wasn’t done, removing himself from his hole, Error guided Blue to get on all fours. Looking back at Error weakly, he leaned down and spread his ass. His hole throbbed and his cock softly leaked the remnants of his seed.

“I’m yours Error, fuck me… Let me pleasure you…”

Panting Error forcefully thrusted his cock back in, growling with a ferocious desire that consumed him, pounding into Blue’s small frame. Gripping his hips he went as hard as he could, forcing Blue to cum again and again until every drop was spent. Leaving nothing but Blue dazed, his face twisted in pleasure as his body softly convulsed.
It was like a high, everything felt like a dream, a beautiful pleasurable dream.

With a final thrust Error filled him, every pulse sending waves of bliss through Blue. Error panted, sweat beaded down as he looked at Blue’s state. Smiling he pulled away, leaving his ass gaping, dripping with thick streams of cum.

Then sitting back Error guided Blue into his arms, holding him sweetly as he rested against his chest. Softly stroking his head and shoulders, letting him come down from the high of their lovemaking. Blue looked up at Error, dazed and trembling from the experience. Error looked at him softly, kissing his head as they cuddled in postcoital bliss.

Chapter Text

The castle stood quiet, it’s dark bricks decorated with stars and moons almost glittered in the moonlight.
Inside the centermost ballroom Nightmare sat on his throne alone, staring off lost in his head. The boys were gone, off on another mission, leaving him to his own devices. 

Which is what he wanted, he didn’t want anyone to be around when he was like this.

Standing up he huffed as he looked at his tendrils, they wiggled and writhed against his will. Normally they’d obey without question but recently he’s been overwhelmed. His mind raced with longing and lust, making him unable to concentrate on his work while also making his tendrils harder to control. He didn’t want them to see him weak, especially Killer who was so loyal he knew he’d hop on the chance to hop on him.

The idea made him shudder as he turned into the endless hallways, their wall decorated with paintings, the floor lines with fine red decorated carpet that contrasted against the blues and purples of the castle interior. He walked trying to burn off the nervousness he felt. But he was so lost in thought he had no idea where he was, looking around he found a strange ornate door, it was a giant mirror with door handles that split in the middle.

Pushing it open he was astounded at the sight, a hall of mirrors laid before him. The glance reflecting the glow of the moon and the vines of roses that grew overhead, intertwining into the decorative rod iron. He stepped in seeing himself reflected into infinity, the mirrors fashioned in a way that created a complex illusion of space. He looked at himself earnestly, his tendrils rising and twitching erratically, his goopy body and his cyan eye gazing at himself.

He sighed resting his head on the glass, not sure what to do with himself, not sure how to make himself feel normal. But before he could turn away one tendril grabbed his arm. A bit annoyed he pried it off himself until another did the same. In a panic, he tried to rip them off 

“THE FUCK!! YOU OBEY ME!! STOP THIS IMMEDIATELY!!”

But his threats meant nothing as they pressed him against the glass, two pinning him as the other rubbed him through his pants, forcing him to groan.
He squirmed in their grasp, trying to pull away “NO! YOU CAN’T DO THIS!”
Until they wormed their way into his shorts, their touch forcing his ecto to form, allowing them to wrap around his hard cock, stroking him.

Taking his wrists they lifted him in the air, removing his shorts. He tried to protest but one slid into his mouth shutting him up. He moaned and struggled until one gently started to tease his ass, gently prodding at his hole until it slid in, making him groan loudly. He tensed, trying to kick at his tendrils until they hit the best spot in him, making him arch back as his eye rolled.

He looked over to the mirror seeing himself in utter bliss, his face contorted in pleasure, the scene surrounding him and he couldn’t take it. He couldn’t stand the sight of him in such a state. Every ounce of pride died as he could that on a carnal level he wanted this.

His whole body started to heat up. He relaxed into it, drool dripping down his mouth and the tendril fucked his face, his tongue lulled out. His legs now limb moved with each thrust as he periodically convulsed.

It was almost maddening, he didn’t just feel himself but the pleasure of the tendrils ontop of that. It all felt so good, that he could barely handle it. He could feel himself getting close, he panted and moaned as it left his mouth. Leaving trails of drool to drip down his face and chest.

Arching back he came, his cock throbbing out thick ropes of cum that littered the floor in his ecstasy. While his orgasm spurred on the tendrils, their cum filling and covering him in another harsh wave of bliss that left him a blissful mess.

Still holding him up he looked high off the feeling, smiling manically as they gently set him down.

Stripping off the rest of his clothes he smiled letting his ecto shift into his female form, his large breasts and ample curves now fully there, he couldn’t help himself. 

His pussy dripped in longing as he fingered himself wildly, cum dripping from his ass. Looking at his tentacles he moaned out desperate pleas for more.

“Fuck I can’t stand it! Please fuck me! Fill me! I need more…” Sitting on the floor he spread his legs as his tendrils overwhelmed him, their touch caressing his body as he gently jerked a few of them off. One went to his pussy teasing the entrance with strong laps. He squealed in pleasure, fully lost in the moment. “Do it… Fuck me…” He panted out, his voice ragged with longing.

As if responding to his pleas it entered him sharply, pounding into him without mercy. Making him throw his head back with a yelp of surprise. The feeling of fucking and being fucked makes his body shake, being driven to orgasm over and over as each ride filled his tight pussy. But he couldn’t get enough. Fucking himself harder the feeling making him cum again further swelling his stomach, making him look almost pregnant.

He panted as his pleasure filled the halls echoing throughout the empty castle, leaving him a cum filled mess.

A few days later Killer, Dust, and Horror returned home, chatting amongst themselves Killer stops and takes a whiff. He smiles madly and bursts out laughing as they walk to the ballroom where Nightmare sat, looking much happier than before. The others told them about the mission, gave reports, and explained the results.

But Killer raised his hand excitedly, interrupting Dust who glared at him annoyed.

“HAY BOSS! Why the fuck does the whole castle smell like fucking cum?!”

Dust face palmed Horror wasn’t paying attention and Nightmare blushed cyan as he stared at Killer in horror as Killer went off upset he wasn’t invited.
