Thank you guys so much for supporting my content! It keeps me motivated when I get interactions here. For anyone here who liked my AgeRe fic for Underswap, I have more! I have another Tumblr Blog dedicated to age regression fan fictions. I have two intros out right now and I'm working on finishing the one that already has the most interaction.

(I know this isn't what I promised when I said I'd write an Asriel X Reader fic. And it's pitifully short. but I kinda just got an idea and couldn't ignore it. I also can't find it in myself to write lewd things about such a sweet boy! But you know what I can write? Muahahahaha... I blame k-dramas)

Adult Asriel X Reader (Final Part)

“What do you mean that can't be true?! You saw it yourself! Don't you remember what they did to you?” I shouted.

“Wait! How do you know that?!”

“I don't know why, but it seems that a lot of monsters know your story. I thought you knew. Since Alphys revived you as a flower-”

“What?! She did that to me?!”

“O-oh my god… you didn't know?”

“I woke up as a flower in my dad's garden.”

I held my hands over my mouth in shock. It was a horrible thing to discover, but I couldn't let him lose himself in anger.

“I'm so sorry. But! You know, everyone told your story throughout the underground. Everyone thinks of you as a hero. Please. If you just let them go then I know they'll forgive you! Especially if… if you take my soul. You can break the barrier and save them all. This is your story. Not mine. I won't let it be my story. And there's nothing you can do to stop me.”

Asriel's expression softened. But there was still fire in his eyes.

“You said you hate humans. If I took them to the surface and it's even worse than being trapped down here… will… Will everyone turn on me?”

“They'll understand. I know they will. Because monsters are good.”

“I don't think all humans are bad.” Asriel told me with a little smile.

“Then don't disprove that by trying to let me be the hero instead. I'm not giving up.”

“I know. Your soul is the color of determination. I know just as well as you do what that means.”

“Go find some good humans. Okay Asriel?”

Asriel hung his head low.

“I will.”

I felt like I died a lot during that journey. But it barely lasted a second. It was barely enough to even process. In fact, I didn't realize I had ever died before I started to get used to the feeling. But when I made the decision to let myself go, it was different.

My body disappeared again. I could feel my connection with it disappear forever. Yet, I could feel the warmth of Asriel's body. He held my soul, all that was left of me, in his hands. I was so close to his physical heart and I knew that I could sink into it if I wanted. So I did.

When I joined with all the souls, I understood them. I suddenly knew all of their stories. I could hear all their thoughts and communicate with them. In less than a second I learned things about all my friends that I had never known. But all except seven left soon after I joined.

That's right. Seven.

Asriel's Pov

It took a while for the monsters to trust me again. But they forgave me right away. It was painful to realize what I had really done to such good people. And they didn't even know half of it. Because of the power to reset, they didn't remember. I was the only one who knew everything. And I had to take responsibility for that.

I stood near the edge of the cliff we found when we first broke the barrier.

“Alphys… I killed the only good humans I know. If I’m going to live how they wanted…I'm gonna have to make it even by killing the bad monsters.”

(Heya! I've seen all your likes on my post about Asriel. I know it's taken a while but I might get back into writing. I know that I'm usually fully boarded on the smut train but after going through Asriel's story I couldn't bring myself to taint him. I hope you enjoy this anyway! I'll add the next part soon!)

Adult Asriel X Reader (Part 1)

I have done it around 20 times. Reset. Over and over again. Obviously the first time I fought Asriel I was scared. He was so strong. Everything about him absolutely radiated power. The second time I fought Asriel I was still in shock over the fact that he was the tiny, annoying flower I was always followed by. The third time I started to realize some things. He wasn't as strong as he looked. Sure he had ten times the power of everyone in the underground. He was also able to recognize me after I reset. But… It seemed like his memories were only a faint dream. And soon enough he forgot me again. And I won against him every time. It was unfair to me. So I kept resetting. I did everything I could to figure out why everything happened the way it did. There had to be a way I could change it. There had to be a way I could save him. Part of it was pity for him, part of it was the hatred of my species. I think the real reason I wanted to save Asriel was for the people in his life who were left behind. And even the friends he could have made. It just wasn't fair to me that he would have to live without a soul in a body that didn't belong to him. It sounded like torture to me. So I kept fighting him in all his strongest states. I kept asking him for answers. And I kept trying to convince him to give me a chance. But my voice wouldn't reach him.

“After I defeat you and gain control over the timeline, I'll just reset everything.”

I would have loved to give him a chance to do that. But I couldn't die. Even if I tried to. And I genuinely tried. Something in my soul just wouldn't break. So I assumed there had to be another way.

“And you know what the best part is? You'll do it. And you'll lose to me again.”

Did he somehow know exactly what my plan was? To keep resetting like he wanted? But when it would happen he sure didn't seem happy. And he never knew either…

“I'm not ready for this. I'm not ready for you to leave. I'm not ready to say goodbye to someone like you again.”

But maybe part of him did? I could never find out. Because in those moments I was always paralyzed. I could only ever move my soul. After trying, and trying. I could only think of one way to communicate with him. No matter what he hit me with, I'd move my soul as close to him as I could get. I stayed there until he finally noticed.

“What are you doing?! Finally giving up?”

Finally. For the first time in who knows how long, something changed.

“... W- Answer me!”

With a wave of Asriel’s hand I could finally speak. It took me a moment to realize it as I raised my hand to my throat. Almost to check if my body and voice were still there.

“Hey! Tell me why you won't fight!”

I looked back at him. Startled.

“I can't. Not anymore. Don't you know how long we've been doing this? Don't you remember me?”

“Obviously I do! I'm completely in control of resets now! I know everything… you … did. Why. Why do you keep doing this? What's the point?”

“I don't want to lose you either! Don't you get it?! I can't go on knowing I'm leaving you behind. Knowing everybody will. It's not fair!”

“You're damn right it's not fair! That's why I'm keeping you here forever!”

“You can't. What are we going to do? Stare at each other for eternity?”

“You've come this far.” Asriel's eyes narrowed and his tone became harsh. “If you really care so much then why fight me up until now.”

“I don't just care about you! I won't let you hurt my friends either!”

“Oh yeah? So when you reset everything that means that everything they all went through just goes away? You know they can remember. You've seen it.”

Sans was absolutely aware of my resets. And I don't know how many others had the same deja-vu when they saw my face “for the first time.” I could almost tell when they would tilt their heads and hesitate to speak. Like the recognition was just barely registering.

Tears filled my eyes.

“I don't know what else to do! You won't let me just talk to you! I keep trying to- to tell you!-” I sputtered through sobs.

“Rrrrggh! All of you keep saying that! Like talking will solve everything. Like you can just tell me to care again and I'll be able to do it!”

“But you can! You have the souls now! Just let go of my friends!”

“What do you think they'll do when they find out I took the human souls. Aren't you human? Why let me take the souls of your people?”

“I hate humans. Why do you think I spend so much time down here?”

“You hate them? Your own species. Why.”

“Humans are even worse than you all think. That's why I can't just let everyone go to the surface. I know the hell waiting for them.”

“That's… that can't be true.”

Fell Sans X Reader (Final Part) NSFW Warning

So, the next while was spent flirting my way through encounters until I met a familiar figure. Sans had his back turned to me. So it seems I had snuck up on him.

“Oh. It's you again.”

“Ah! Wh- Oh. Hey.” Sans said as he turned around quickly.

“Surprised I'm not dead yet?”

“Well… uh… I've been watching you so… yes. Haha…” Sans said awkwardly as he rubbed the back of his blushing skull.

“I hope you don't think I'm a tease. I'm doing this for my own survival, you know.”

“Er! I know that. And what does it matter what I think?!”

“Because you're my favorite.”

Sans’ adorable eyes went wide as his face became completely flushed in dark red.

“You… You're just a slut!”

“That's so mean!~ I'll prove to you I'm not a slut. I'll never flirt with anyone else if you agree to protect me.”

“Shut the hell up. You're just trying to trick me!” Sans’ voice cracked as he spoke.

“Is that your way of admitting it's working?”

I got closer to him. Sans tried to back away but I put a hand on the shoulder still closest to me and leaned in. The poor thing made the quietest, most adorable squeak in response.

“I'm really thankful to you. For sparing my life that is. Why don't you take me home so I can repay you?” I whispered.

The skeleton stumbled backwards as if his knees buckled.

“Agh! Fine! Just… You can't come up to me again after this. Alright? I have a place you can stay for a bit where nobody should find you.”

“You're such a good boy~”

“Knock it off!”

Someone not far away started talking. I didn't have a chance to process what they said before Sans took my hand and I blacked out.

When I came to, I found myself in a beautiful grassy cave. Brightly lit by glowing blue flowers. Especially after waking up like that, it felt like a dream.

“Where… is this?”

“It's a hidden cave nobody seems to have noticed yet. I've even tested out if anyone knows about it. Left a whole shit ton of money in here. There's no monster down here who wouldn't take it.”

“Did you teleport us here?”

“Yeah.”

“Then maybe it's just impossible to get to.”

“Haha. I didn't find it by teleporting. If I teleported around randomly I'd kill myself getting stuck in a wall.”

Good. That means there's a way out. I don't know if skeletons eat so I don't want him to accidentally starve me.

I laid down in the cool grass. Exposing my midriff to Sans accidentally.

“This is really nice.” I said as I stretched out. “I hope I don't get too cold.”

“Well… I may not have much body heat but I think I can uh… warm ya up.”

“Oh yeah?~”

“W-well! That's what uh. That's what I brought you here for. Right?”

It was a stupid thing to do but I couldn't help but mess with him.

“How rude of you. All you want from me is sex? Are you planning on abandoning me here afterwards?”

“Uh! W-well I-”

“I guess I shouldn't be surprised. People like me are never loved for our personalities.”

I rolled over and crawled up to Sans. I put a hand on his chin and lifted it up to meet my face hovering close to his.

“Promise you'll look at my face more. Okay? I don't want you to like me only for my body.”

Sans' adorable face was flush with deep red. I could see his sharp teeth glint in the dim light.

“Y-yeah. No problem.” He said softly.

“Good. You'll let me take the lead right? I get intimidated by big scary men like you when they try to dominate me.”

“Uh y-yeah? Hehehe uh. Sure. I mean uh. You can do whatever you want.”

“Perfect.”

First, to satiate my curiosity I kissed him. To my surprise, it seemed that Sans had lips of some kind. They were small, but they were warm and soft. I let my tongue poke at his sharp teeth. As I hoped, they were more dull than they appeared. Sans moaned as my tongue entered his mouth. Pretty soon he started to force his tongue deep into me. But I bit down on him.

“No~” I said through my closed teeth.

I pulled my face away from him and said,

“You don't get to do that. Mommy is taking the lead. Got it? Now what do you say?”

“Ughh~ Yes Mommy!”

I pushed Sans down into the grass and started grinding into his hips. Originally I didn't know if he had a penis or not. But I soon found my answer.

“What a good boy. You're already so hard. Did you like my kisses that much?”

Sans nodded frantically.

“I'm glad. Do you want more?”

“Yeah! Uh- Yes Mommy.”

“Where~” I said as I pulled down his pants to reveal a short, thick red cock. It was so vividly colored it seemed to glow.

“Ugghh~ M-my dick. Please.”

“What a good, polite boy you are.”

I started with what I had promised. I kissed the head of his dick all over until I was satisfied. Then I explored with my tongue. His precum tasted very earthy. Like tea.

Is this what magic tastes like? That must be what his penis is made of.

I took the affection up a notch and started giving Sans a proper blowjob. Savoring the taste of his odd, and fascinating member.

“Ahhhh!~ Ahh! Aghhh!”

He's so sensitive. How cute.

His overwhelmed moans eventually turned into impatient whines. I looked up at him, dick still in my mouth. When we met eyes Sans moaned again with an erotic expression on his face as he fell back into the grass. I laughed a little and moved up.

“No! Don't stop.”

“You don't get to tell Mommy what to do. Or else… you won't get to find out what Mommy wants to do.”

I sat up and unbuttoned my blouse. But, I stopped before revealing my breasts.

“Now. What do you say when you've been naughty?”

“A-ahh. Sorry Mommy.”

“Good boy.”

I opened my shirt and leaned down again to give a boob job. My large chest easily swallowed Sans' cock. Which he seemed to enjoy just fine. I loved the desperate look on his face as I bounced my tits on him. He started humping me. Just barely. Like he was trying to do it softly enough that I wouldn't notice. I let it slide. But only because it was cute. Suddenly his dick felt very hot, and Sans groaned loudly and picked up the pace. He started desperately humping my chest like an animal. It reminded me of riding a bull. So I took the challenge and moved with him to make the sensation even stronger.

“Aaahhhhhhgghhhh!”

Soon, Sans came to a climax. Red, translucent liquid shot through my boobs. He came so hard it had enough force to even go past my large chest. It was so hard I could feel the way his cock convulsed as it shot out his semen.

“Oh my. You made quite the mess.”

“I-I’m sorry Mommy.” Sans whined.

“That's okay sweetie. Will you take me home so we can get cleaned up?”

Sans nodded and grabbed my hand.

And I suppose that's how I ended up living safely with Sans.

(Sorry this was so short. As you can probably tell Im having quite the writers block and I'm going to be taking a break for a bit. Thank you for supporting me! It helps a lot. I promise I'll be back with more Undertale content and maybe even more content for other fandoms.)

Fell Sans X Reader (Part Two)

So I went back up to confront Toriel. As I assumed she would be, she was in the kitchen.

“Who's Sans?” I said bluntly.

Toriel jolted and turned around.

“H-how do you know that name?! Did you go to my basement?”

“Yes. You shouldn't expect me to not become concerned. You spend a lot of time there and it's suspicious.”

“I'm just… talking to a friend…” Toriel muttered defensively.

“Who is he?”

“He's dangerous and you shouldn't talk to him!” Toriel huffed. “That's why I never open the door.”

“Is he really dangerous? What kinda magic does he have?”

“Well. None right now. He got hurt and he can't use his magic until he recovers. But he's still dangerous. His brother is the captain of the royal guard. If you were seen with him you wouldn't be alive for long.”

“I see. That does make him pretty dangerous.”

I already had my heart set on meeting him. Something about the mysterious man interested me. Or maybe it was being trapped in Toriel's house that was driving me insane.

The next day I once again snuck downstairs after Toriel's usual meeting.

“Hey. It's me again.”

“So? What did Tori say?”

“She said you have no magic. But your brother is the captain of the royal guard so you'll probably do anything to hunt me down.”

“If that was true then why would I be sittin’ here on my ass all day?”

“Hmhmhm~ I guess you do have a point there.”

“You're safe for now. Open the door.”

“You sound like a cartoon villain.”

“If I'm a cartoon villain then the good guy should be able to escape right?”

“You keep accidentally admitting you're going to attack me.”

“Ah! I- No! That was a hypothetical!”

“Oh really?~ So why am I the hypothetical good guy? Do you already think highly of me?”

“N-n-no! I-I- Raaagghh!”

“Hahahaha! You're so easy to fluster. I really do want to see your face now. What kinda monster are you?”

“None a your business! I- I got stuff ta do!”

I heard him start to walk away. Before I could stop myself I opened the door and took a peak at him. He was a short skeleton wearing a warm black and red outfit fitting for the snowy forest outside. He must have had amazing hearing because nearly the second I opened the door he turned around. His eye sockets were so big and cute I forgot to run. They also had a strange feature. One was glowing with a red blazing circle. Like a pupil.

While I was staring, Sans took his chance. My body suddenly felt an extremely strong sensation and I couldn't move at all.

“Hey! I thought you didn't have magic!”

“I didn't. Two weeks ago at least.”

“Rrrg! You bastard!”

How do I get out of this? He seemed easy to fluster before…

So I straightened my back and stuck my chest out a bit.

“Ugggh~ This paralysis feels strange~”

As I assumed, Sans’ magical hold on me immediately stopped.

“H-hey! Do-don’t uh. Do that.”

“Do what?” I said as I strutted up to him. “All I said was that your magic makes me feel strange.”

“Woah! Hey! Wait!” Was all Sans could get out before I swung a closed fist at his jaw.

Somehow, he dodged out of the way.

“Hahahahaha! Shit! You're a spicy woman!” Sans laughed.

I don't know why I thought I could knock him out. He was all bone. But I still had to try. Not that it ended up mattering. I stumbled back and held up my fists ready for a real, but most likely unfair fight.

“Know what? I won't try to capture ya. You're gonna be dead by the end a’ the day anyways.”

“What? You're… letting me go?”

“Yeah. I didn't think you'd be throwing punches. I kinda wanna see how this plays out. But. If anyone asks… You never saw me. Got it? I'll be watching.”

And somehow, the skeleton disappeared in a blink. I didn't know where to go from there. He was right. I couldn't take my chances with other monsters. So I turned around to go back into the ruins… but there wasn't any way to open the door.

“Shit! No! This doesn't make any sense!”

I tried to squeeze my small fingers around the thin gap between the door and the wall but it was too skinny. There was no handle of any sort or even a slightly raised surface I could somehow get leverage on. There was almost no space under the door either. I had no choice but to continue forwards.

In not too long I came across a strange bird with plumage like a snowflake.

“Hey! You're a human! Freeze!”

“Shit…” I whispered under my breath.

I wonder if the same method can get me out of this mess too?

“Hey! You're not stupid are you? Get it? It's a snow pun.”

The stupidity of the situation made me laugh. I didn't expect the little guy to tell jokes.

“Hahaha. How cute~”

“Uh! Um…um… no I'm n-not.”

“What are you doing all the way out here alone?~”

“Uh! I-it's none of your business! Die!”

The bird threw some kind of small useless attack at me but I barely needed to dodge it.

“Poooor thiiing~ If you stop being naughty I can help you get home~”

“Aa-aah I-I don't-” The bird squawked in embarrassment and hopped away.

Maybe this won't be too bad after all. If I can keep this up that is.

Fell Sans X Reader (Chapter 1)

Apparently, I was the first adult human to fall into the underground. I figured it out when I came across a scary looking goat woman.

“Oh! You're… you're a human. But… You're much older.”

“Excuse me? I can imagine I'm around the same age as you!”

At least… if that's how age works for monsters…

“Oh! No no. I'm sorry I meant… I've never actually seen an adult human before.”

“Oh… really? Is that why you all seem to be acting so strangely around me?”

“Well. Humans aren't necessarily liked.”

The goat woman told me of the history between humans and monsters, and introduced herself as Toriel. I introduced myself in turn, and asked if monsters were dangerous for me to be around.

“I'm very sorry but… I'm absolutely sure they will try to kill you. Not only do most other monsters have an extreme animosity towards your kind, but… well. We may have devised a method to escape to the surface. But it requires a human soul.”

And that's how I became Toriel’s roommate for quite some time.

“Y/N~ I made breakfast. Don't sleep in too late or it will get cold.”

But I didn't appreciate all the belittling behavior from her. I understood that she was very lonely but that wasn't an excuse to coddle me.

“You can eat as much as you want. If it gets cold I can make breakfast myself.”

I regret being so rude but I was growing very tired of Toriel's attitude. She got huffy with me that day and once again I heard her stomp down to the basement.

That really is an odd basement.

Toriel's basement had an absurdly long hallway that led to an ornate door. And that was it. I had no idea what Toriel would be doing down there. She would spend hours there with no word about it. I decided to finally check it out. I hid just down the hall as I heard Toriel walking up. Once she made it to the living room I quietly ran down the stairs and down the hall.

I don't know if I'll catch what she's always doing down here. If I don't see anything I'll confront her directly.

I made it to the door and was unsurprised to find nothing out of the ordinary.

“Dammit. *Sigh* I guess I'll have to try again later.” I said to myself.

“Hey. Who the fuck is there?!” I heard a gruff, deep voice beyond the door.

“Ah! I- is this what she's always doing? Um.” I spoke up more. “Hello. I'm Toriel's ahh… roommate. I'm sure she's told you about me.”

“No she hasn't. Who the fuck are you. Toriel hasn't said anything about someone else being back there.”

“She… hasn't?”

That definitely sounded strange. But my thoughts were interrupted by a loud slam on the door.

“Eeek!”

“Are you gonna answer my question or not?!”

“I-I-I'm Y/N! I'm a human that fell down the mountain and ended up here!” I sputtered out without thinking.

“...you're a human? Hmmm. Ya know what. That actually makes sense that Tori didn't say anything about cha’. Hey. Why don't cha open the door? Let's talk this out kiddo. I'm not that scary.”

I told him my age.

“O-oh. Um. Sorry ma'am-er! That doesn't change anything! Open the door.”

“Even if I didn't know you're probably planning on immediately killing me, I would never open the door for someone so rude.”

The man behind the door growled. “So she told ya about that then?”

“Yes. I may not like it much here either but I'm not stupid enough to walk right into a death trap. I know monsters have magic too.”

“Ya? So you know what my magic is?”

“No. I don't know who you are.”

“Go ask Tori. Ask her what she knows about Sans.”

“Is that your name?”

“Yup. Go on. I'll wait. I got nothin' else ta do anyway.”

“I… I don't think she'd like it much if she knew I was here.”

“Ha! What. Ya scared of her?”

“It's not that. She's just… Hmmm… A bit controlling.”

“Is she tryin’ ta keep you there or somethin’?”

“Haha. I wouldn't be surprised… Hmmm. Maybe I will ask her about you then…”

Sorry this is short! I wanted to put it out so you all had an idea of what this story will be about!

Fannon Sans: I FUcKIng LOvE KetcHUP!

Cannon Sans: can ya stop giving me these? I don't actually drink ketchup. it was just a party trick. I washed out the bottle and put something else in it.

"Really? What did you put in it?"

"Juice? That's kinda childish."

"You drink wine?"

"I don't believe that for a second."

"Okay fine! It was straight vodka dyed red!"

Sans X Reader X Grillby (Final Part)

NSFW Warning

And then I leaned in and kissed him.

I wasn't usually into the idea of making out with my fuck buddies, but I couldn't help it. The idea of completely overwhelming Sans with affection sounded really hot to me. As soon as I noticed Sans begin to calm down, I let my tongue explore his mouth.

“Mmmnnnn!~”

Both Sans and Grillby were so much more expressive that night. It was really entertaining.

“Aaah! N- wait! Y-you're gonna put it in there?!”

Suddenly Sans pulled away from me to shout at Grillby. Having an idea of what was going on, I looked behind Sans. Grillby's orange, glowing hand was lower on Sans' ass than it was before. If I leaned over more I would have been able to very clearly see Grillby's pointer finger inside of Sans' asshole.

“Aa-*gasp!* ahhhhh!~ Noo!~”

The way Sans' body shook and the shocked expression on his face tore me away from the sight of his ass being pleasured. Sans closed his eyes tight. He looked like he was trying to calm himself down. I wasn't going to have that. I knelt down beside Grillby and lightly licked what I could reach of Sans' balls. The ever polite Grillby then released Sans' dick from his mouth and moved to licking it so we could work together. As I was hoping, when I looked up at Sans' I caught him looking down at both of us with the most adorable shocked expression.

“Y-you guys… Ahhh!~ Wait! I- Haah~ I c-can’t cum like this!”

“Mmmnn *suck* I think you can. But I'll help a little.”

Grillby started pinching and fondling Sans' balls as we tongue battled for who would get to have him. It didn't take long before a sheer blue liquid sprayed all over our awaiting faces.

“Aaahhhh!~”

“See? I told you I could make you cum that way.”

“Tha-*huff* That's not what I meant!” Sans insisted, his face bright blue.

I was so excited to see what his semen tasted like, I pushed Grillby's face away with my cheek and happily sucked on Sans' cock.

“Aaahhh!~”

“Oh you're a very rude little boy. So selfish. Do I need to punish you?”

I nodded. Still attached to Sans' dick, I could only hear as Grillby got up and walked behind me.

*Slap!*

I was expecting him to hit me, but I wasn't expecting it to hurt so bad.

“Mmmnnnphmm!” I screamed through Sans' cock.

“Ah fuck…” I barely heard Sans' whisper above me.

Suddenly my pants were pulled down and Grillby shoved his penis in my ass.

“Aaah! Wai-gaaahhggg!”

It was a bit too big to shove in like that, but I couldn't communicate it through Sans' thick cock. I shook my head but that only got Sans more excited. Exactly as Grillby fully entered me, Sans grabbed my hair and deep throated me. It was only seconds before my body tensed and I came onto the floor.

“Mmmn~ You're having that much fun already?” Grillby teased as he ran a finger along my dripping cock. “But I'm not letting you go. You're gonna be a good boy and let us use you until we're both done.”

I tried to shake my head but Sans' grasp on me was firm. I knelt there and took it like a good boy until Grillby came in my ass. I didn't have time to scream before Sans quickly followed suit and I choked on his cum.

“Haha. Yeah. Come on. Swallow it up. This is what you wanted. Right?” Sans taunted.

I collapsed onto the floor… and I don't remember anything else until I woke up in Grillby's bed that morning.

“Mmmnn… Grillby? What are you- ah! Am I-?!”

“No no no little boy. Lay back down.” Grillby chided as he gently pushed my body back onto the pillows.

“You fainted last night. I think we were a little hard on you. I'm sorry. We forgot how fragile humans are. Sans and I are going to make it up to you today. Okay?”

I was so tired I simply nodded and fell asleep once again.

(Sorry for the short final part. I've been having writers block lately. I'm going to make that Fell Sans fic and then I might take a break for a while. Thank you all for your support!)

What's getting him horny now?! Is he a sadist?! Oh God. This was a huge mistake. A sadist and a monster is a very terrifying mix!

“Haaah!~”

I wasn't wanting to get beat up that night, but Sans wasn't very powerful. If he wanted to hurt me he'd have to put in a lot of effort. So the fear wasn't overpowered by my lust.

“Hey. Grillby. I think he's had enough.” Sans told us suddenly.

No! You choose now to be a wet blanket again?!

“Ohhh…” Grillby sighed. “Do you think I'm being too hard on your friend?”

“Nah. It's not that. I just think you should take off his shirt now. And maybe we can make him sit with us like that for a while.”

“What?!”

“Ooohhh Saaans~ You're finally joining the fun. I'm so happy.” Grillby said as he slid his hands up my hips and took hold of my shirt.

“A-aah!”

He pulled up on the shirt with such force I couldn't keep my arms down. And he successfully undressed me. I was now standing in only my underwear, socks and shoes. Sans made an expression of slight interest at the sight of my naked chest, and casually put an arm on the bar and leaned over a bit. Still very obviously checking me out.

“Wha-ha-ah! W-what’s the deal with you?! Why are you- l… looking at me like that…” I asked shyly.

“What. Have a problem with it? I can stop and you can put your clothes back on. Maybe I was right. Maybe we shouldn't try to force anybody tonight.”

“Rrrr! If you think you're getting revenge or somethi- Hey!”

I forgot Grillby was behind me. He picked me up easily and sat me down on one of the bar stools.

“Now be a good boy. Maybe Sans will strip down too.” Grillby offered.

“Yeah. Tell me you want to see me naked and I'll do it.” Sans told me.

“What?! You're kidding.”

I knew he just wanted to see me squirm. And I knew I couldn't muster the courage to say it without faltering. I had to choose between my pride and my penis. The correct choice was obvious to me.

“C-can I- er. Uh… I really want to see you naked. Sa… p-please.” I whispered.

“Oooh. What was that? Were you wanting to say my name?”

“Uh!” I quickly turned back to my drink. The condensation dripping down the glass reminded me it was nice and cold. So I took a sip to cool my hot and bothered body.

“Do it. Say my name.”

“S…sans…” I murmured, eyes still fixed on my drink.

A flash of blue light appeared on my left side. Before I could figure out what it was, my chair gave out from under me somehow. I fell onto the floor.

“Look at me and say it.”

I looked up and Sans hooked his pink slipper under my chin. Forcing my head up at an uncomfortable angle.

“Sans!” I panted.

*Tszzzz*

“Fuck!”

Sans and I turned to see Grillby leaned against the counter tripping over himself doing… something. Sans looked over and I stood up to see what it was. Grillby ran to the back of the bar behind a wall. Sitting on the bar was a small blob of something orange-ish red and kinda black. I reached over to touch it and...

“Don't. That's magma. Heheh. I guess Grillby was drooling. Like… literally drooling at us.”

I snickered at that just as Grillby rushed back into the room with a large silvery towel. He put it over the magma as a small fire had started on the table.

“Rraaagghhhh.” Grillby growled.

I had never seen him so mad. Before that night I hadn't seen Grillby showing much emotion at all really.

“You're really fired up today.” I accidentally joked.

“Pftt Hahahaha! Nice one man!”

“Ah shit. Heheh. I didn't mean to make a pun.”

Sans was far from his sadistic, horny mood now. I wasn't getting anything else out of him. I sighed and turned to Grillby. He looked furious. He pointed to Sans and said,

“You. Strip. Now.” In a terrifyingly demanding voice.

Sans simply shrugged.

“Eh. I don't like to break promises. Guess this might as well happen tonight. Sorry Y/N. Hope this doesn't make things awkward.”

Sans hopped off the bar stool and slid off his jacket.

“Heheh. Don't worry. You can go back to your own place after this and drink until you forget it.” I offered.

“And what about you?” Sans asked as he pulled up his shirt. Showcasing a set of thick ivory ribs and… a blue jello-y looking torso underneath it?

“Uhhhhhhhhhhh.”

“Hey. Don't get all flustered yet. I haven't even gotten to the good part.”

“Wh- uh.”

I was shocked to hear that Sans had confidence in his package. He slid off his pants and showed me exactly why. Underneath his pants were no underwear. Which I didn't understand since he had a somewhat normal body, but he was also sporting a mostly erect penis.

Aggghhh! He's huge! That's not fair! I can't believe of all people he'd be the guy with a big dick!

Sans' member looked about five inches. Which isn't impressive, but the girth was insane. I could tell he was still not fully up yet either. So it had to be six or seven inches at most.

“Oh God…” I muttered without thinking.

Sans' penis twitched at my accidental compliment.

“Aw Jeez. You're makin’ me blush.”

“Errr uhhh. I just uhhh- I didn't know skeletons would have those.”

“Yup. You look like you don't believe it. Are you wanting to come make sure it's real?”

“Well now that you say that~ I'm almost convinced it is fake! I better check.” I said, nodding.

“You might have to get in line. I think it's only fair if Grillby checks first. You okay Grillbz?”

Grillby was standing dead still, staring at Sans. He didn't seem like he had that much alcohol before, but he was clearly plastered. I couldn't think of any other reason he would be acting so differently that night.

“Um…” Grillby shook his head and looked up at Sans’ face. “Yes. Sorry. You're just so… captivating.”

“Ah!-”

Now a compliment like that got Sans going. He stuttered nonsense and looked down to the floor. Only to quickly notice that his dick had swelled in appreciation of the compliment.

Good to know. Sans has a bit of a praise kink. I wouldn't expect such a laid back, lazy, kinda sloppy guy to be a sadist with a thing for praise. I'd expect that from Mettaton or something.

Grillby passed me and took hold of Sans' shoulders. He slowly slid his fingers down Sans' arms, down his blue jelly torso, and paused just above his dick. Knelt on the floor, Grillby started gently running his fingers up and down the thick shaft.

“I can't believe you've been hiding this from everyone. Scared you're gonna break somebody with it?”

“Mnn…Heheh. It can't be that big.”

Sans was maintaining his confidence, but it wouldn't last very long.

“Oh that's riight~ My little skeleton has never seen a pussy before.”

“Hey. Don't call me-”

“Pft. Wait, really? You've never seen one at all?” I interrupted.

“Hey! It's not like I could have just-*gasp* G-Grillby! Aaahhh~”

And Sans was interrupted once again by Grillby now putting his mouth around Sans' cock and slowly sliding forward towards his ecto-torso. Sans stumbled backwards but Grillby quickly put his arms around his ass, holding him up. Sans yelped softly as his bright blue butt was suddenly squeezed and rendered immobile. The expression on Sans' face was so passionate I could only assume he had never received a blow job before. I couldn't hold myself back anymore. I went up to the two, and moved next to Sans. He watched me with a mix of fear and embarrassment on his face. That expression only became more apparent when I put a hand on his cheek and turned his face towards mine. I wanted to see how he'd react before I did anything.

“W-w-wai- aaah!~ Y/N. Ah! Grillby!~ Haaahhh-mmn?!”

And then I leaned in and kissed him.

Reader X Sans X Grillby (Part 3)

NSFW Warning

“Why are you two talking about me like I'm not here?” Grillby interrupted.

“Eheh. Sorry.” I apologized.

“You're being weird today Grillbz.” Sans butt in. “What are you trying to do?”

“What do you mean? I'm just having fun tonight.”

“Nah. I don't believe you. Are you trying to get in bed with us?”

Grillby's expression gave everything away. Still, he tried his best to keep his secrets.

“Now why would I do that? I wouldn't risk ruining your friendship. That would be terribly awkward. Wouldn't it?”

I shrugged as Grillby slid us two tall red drinks. I personally didn't think it was weird to have a drunk fling with a friend. If feelings got involved then it would be weird.

“I can't believe you. We're not your toys ya know.”

“Not yet.” I said before I took a sip of the drink.

“Ugggh. You're way too horny.”

“Heheh. I can't help it. I'm a man. Hey, that reminds me. Do you gotta dick?”

Sans spit out his drink and Grillby started literally roaring with laughter. I laughed along with him but I didn't stop the pressure on Sans. I stared at him until he answered me.

“You don't need to know. So I don't need to tell you.”

“So like… it doesn't matter if I grope you because I don't know if you have genitals.”

“That is not how it works!”

“So if I take your clothes off, it's okay if I see you naked. Because I'm under the reasonable assumption you have nothing you need to hide.” Grillby joined in.

“No! You're not stripping me!”

I didn't know how far I could push the subject. Sans wasn't threatening to leave but I didn't think he would threaten to. I was pretty sure he'd just go.

“Yeah. I don't wanna see that anyway. It probably looks weird as hell.” So I tried a different strategy.

“Dude. That wasn't cool.” Sans said.

Just as I planned, my comment infuriated Grillby. He slammed a hand on the table and leaned in towards me.

“What gives you the right to comment on someone else? Are you directing attention away from yourself?”

“What?!”

Sans snickered. That didn't go as planned at all. I was hoping Grillby would start defending Sans’ honor by complimenting him and gushing over him. But instead my four inch was at risk of exposure.

“If you want a dick to be seen I have an idea to accomplish that. Why don't we take a look at your body then? Since you seem so excited to use it tonight.”

“Woah! Hey! T-th-there’s no need for that!”

“Heh. Know what? I think I'll let this slide. Since you seem like you deserve it.” Sans said as he sat back in his chair and took a sip of his drink.

“What?! Hey! What happened to you u not wanting to do that! I-I’m not gonna strip for you guys!”

“You're gonna have to, little boy. Or I might hurt you when I burn off your clothes.” Grillby threatened.

“Aah! Nooo! You monsters are crazy!”

“Heh. Humans. You guys are such pussies. It's just a little fire magic.”

One thing I've learned about monsters is that they get seriously hurt a lot and they don't seem to mind it. Assault and serious injuries aren't really a big deal to them. It's just part of their culture. It keeps them strong.

Grillby put out his hands and made a groping motion as he came around the bar and started moving towards me. Sans was laughing his ass off as I backed away from Grillby. My body started shaking very obviously. It seemed to entertain the two.

“Poor little boy. You really don't want us to see your dick. Do you? Hmhm~ Is it that small?”

Sans attempted to say something but he couldn't get anything out through his laughter.

“Grillby please! You don't have to do this!”

“Ohhhh don't you want me to? I thought you were trying to get in our pants. It's only fair you sacrifice yourself to us first.”

“Noo! Why do you have to say it like that?!”

“Aw come on bud." Sans said. "You're not scared of us. Are you? Come on. What am I gonna do? Throw a bone at you?”

“You're not the one I'm scared of! I'm still one man against two and one of them is made of fi-*gasp!* H-how!?”

Something on my lower back tingled and before I could figure out what it was, my pants were pulled down to my ankles. But nobody was behind me.

“Awww. I was right. Poor thing~” Grillby cooed in a demeaning tone. “You know what? I should stop bullying you. Hmhm~ You're unfortunate enough. You already got what you deserve.”

By that I'm sure he meant I was so obviously small just looking at my underwear there was no need to remove them.

“Heheh. Your face is so red." Sans laughed. "I didn't know humans did that too. Cute.”

“Hey! Don't call me cute!”

“Oh it's much too late for that.” Grillby said as he slid next to me and grabbed my crotch.

“Eeaaa!”

Grillby, a tall man especially compared to me, leaned down next to my face. Still groping me, he whispered in my ear.

“Y/N. I'm sorry. I shouldn't have been so mean about your size. I'm sure once you're erect you’ll be quite delicious- ah. I mean, impressive.”

“A-aahh~ wha… mmnnn~”

My flacid friend was quickly gearing up to show Grillby it's full size. But that also meant that Sans would see too. I didn't mind that idea before I was put on display in such a humiliating way. I tried hard to mask my expression and noises but I hadn't been touched like that in so long. I didn't want to see how Sans was looking at me, but eventually I couldn't take not knowing. I didn't hear him laughing so maybe he wasn't. But seeing him look disgusted would be even worse. I opened one eye and looked up at Sans sitting on the barstool. When he caught me looking at him… Sans smirked and looked me up and down in a way that made me get even harder. I didn't think he was capable of making such a sexy expression.

What's getting him horny now?! Is he a sadist?! Oh God. This was a huge mistake. A sadist and a monster is a very terrifying mix!

Reader X Sans X Grillby (Part 2)

“Well… mmn. I'm sure Sans won't mind if you stay.” Grillby said.

“Woooah. Grillby. Let's not get too crazy.”

Suddenly, I was curious about something.

“You don't want him drinking but you'll agree to be alone with Grillby drunk? Are you guys secretly fucking?” I asked.

Sans’ face went pure blue. He hid behind the table.

“I don't think we went that far. But I definitely wouldn't mind~"

“Hahaha what the hell? What happened? Is that why Sans has been weird all night?”

“My sweet boy~ Are you ashamed of me?” Grillby teased as he looked over the bar.

“Come on sweet boy.” I joked. “Answer the man.”

“Yes. I am.”

“Well we better fix that! More alcohol for everyone.” I said.

I was intending on scaring Sans off so I could have Grillby to myself. But apparently I underestimated Sans' protective nature.

“No way. Nobody is getting any more alcohol. Come on Y/N. Enough fucking around. Let's get Grillby in his house.”

“Stop talking about me like I can't hear you.” Grillby grumbled.

“I know you can hear us. I just don't care. Come on.”

Grillby looked over to me.

“Y/N. Sans is such a party killer. Right?” He said.

“Couldn't have said it better myself.”

“I know Sans. I've known him for years. He just needs a good time. Don't you think?”

“Heheheh. As long as you don't leave me out of it.”

“Oh. Yeah? Giving me a taste of my own medicine now?” Sans sneered.

“Oh~ I'd never leave a cute little boy like you out.”

“Uhhhh. Eheh. I uh. I'm not sure about calling me little boy. I'm a man you know?” I said.

“Okay! I think I've had enough. Drink yourself to death if you want to Grillby. Come on Y/N.”

“What? The hell makes you think I'm leaving? You go.”

“Not a chance.”

Sans has a serious look on his face.

He's not… jealous. Is he?

Before we realized, Grillby had snuck around the counter and grabbed me by the waist. He towered over me by at least a head and a half. 

“Uh!”

“Grillby! Fuck off!”

Now Sans seemed pissed. But by his glare I couldn't tell who he was mad at.

“You're not gonna leave me alone with this maaan~ Right Sans?”

“Hell no!”

“Ohoho?”

“Uh!” Sans had apparently spoken without realizing. His protectiveness and jealousy was now on full display. Grillby backed away from me and went up to Sans instead.

“You only have one option, Sans. Stay with us and have fun for once. I miss you. Why do you think I did so many shots while your back was turned?”

“What?! You did that just to get my attention?!”

“You won't give it to me otherwise. I like to be doted on too some days.”

“Ah! I'm not-”

“If you'd rather leave I'll let Y/N stay with me and make sure I'm safe. You'll be careful with me. Won't you Y/N?”

“No promises~”

“Rrrr. That's it. You're not holding me hostage here. I'm not gonna be tricked into doing something gross with you. Especially not both of you.”

“Jeez Sans. What a way to put a guy down.” I said.

“W-what the hell?! You'd actually do that?!”

“I was considering it. I'm a little too sober for it right now but in a few more drinks I think it'll sound like a great idea.”

It was a little cruel to say, but I was feeling very honest at that level of drunkenness.

“Fuck you.”

“That's what we're hoping for~”

I was oblivious to Sans' rage, but thankfully Grillby wasn't. I probably would have died if Grillby didn't walk in between Sans and I, kneel down and hug Sans around the chest.

“Don't be mad sweet boy. Please let me have fun. Just tonight. Please? I'm begging you.” He said in a sweet whispery voice.

“U-uuh! I-I…”

“I'm an adult Sans. I'd do it anyway if I wanted to. Don't pretend that you have to protect me.”

Sans sighed and turned his head away from Grillby.

“Fine. Just don't go too crazy if I'm gonna stay. Alright?”

“Yes!” I cheered.

“That means you too!”

“Haha alright alright. We’ll go easy on you.”

Grillby and I shared a look. A look that meant we were lying.

“I think we can start off with some special drinks. Right Grillby?” I said.

“Woah hey. I thought you said-” Sans started.

“We mean drinks that taste good. Not shots.” Grillby clarified 

“Oh okay. That sounds good actually.”

Grillby went behind the bar again and started mixing three drinks. I caught Sans nervously looking around the empty restaurant. 

“Hey. Seriously man. Why are you all uptight and nervous? Is there something going on I don't know about?” I asked.

“Uptight? Now that's just mean.”

“It's not like you to be such a wet blanket.”

“Haha. I hope not… uggggh. You really want me to tell ya?”

I smiled.

“Alright. So a couple years ago I fell asleep at the bar here and Grillby got bored and started drinking. I woke up to him… uh…”

Sans turned his face away from me. He was probably blushing.

“K-kissing my head. Heh. Uhhh so I woke up and asked him what he was doing and he started uhh ya know. Just. Acting weird.”

“Yeah? Did you guys have sex?”

“Ahhh. Not really. We got to his room but he fell asleep before I did. And ya know. I kinda have the feeling he wasn't wanting to.”

“Really? He's been really flirty. I would have thought otherwise.”

“I dunno. He's different today.”

“Why are you two talking about me like I'm not here?” Grillby interrupted.

Reader X Sans X Grillby (Part One)

After a long week looking for jobs in Snowden, my friend Sans and I decided to spend a well deserved night at his favorite bar. Grillby's. The food was fine. It was your regular run of the mill diner food. But the reason Sans liked it was because he was really close with the owner, Grillby.

Grillby was a loner type. He was very quiet and polite. Despite the way he looked, he really did have a bad case of background character syndrome. Another thing about Grillby is that he's hot. In two ways. First, he's a fire elemental, and he's also… beautifully sculpted. As a human, I didn't find myself attracted to many other guys in the underground. Maybe Sans a little bit. But only in a “I'm drunk enough to hit that.” Kinda way.

“Hey. Come on. You said you wouldn't make it weird.”

Sans pulled me out of my thoughts suddenly. I was embarrassed to realize I was staring at Grillby.

“I'm sorry! I can't look though?”

“It's weird.”

Sans was a real wet blanket about certain things. But usually he's probably the most fun person to hang out with. He loves pranks, walking around, going out to eat and he's always down to hang out. Even if he's working.

“Fuckin’ hell. You think everything is weird. Come on dude. Lighten up. Let's get some drinks in you.”

“Heh. I bet you a hundred G that you'll get drunk before I do.”

“Oh yeah? Bet.”

A couple hours later we completely forgot about the bet. Sans was a really slow drinker and we wanted food first so it took us a while to even get tipsy. The worst part is that a couple people in the bar joined in on the drinking fest and they beat us by a long shot! It was just starting to turn into a bit of a party. Sans was a very fun drunk, but I had never seen him get drunk at Grillby's before.

“Hmmm… we should head back.”

“What. Does your ass bone hurt? Come on. It's only… uuuhhh.”

I looked around for a clock. While both Sans and I were turned, we didn't know what was happening behind us. Suddenly the bar erupted in a chorus of cheers. We looked around to find what everyone was so excited about. It seemed that Grillby was taking a shot. A couple in fact.

“Grillby no!”

But for some reason Sans was extremely against this. He hopped on top of one of the barstools and tried to take the last shot out of Grillby's hand. But after a couple drinks, Sans was much clumsier than usual. His hand slipped and his skull crashed onto the hard surface of the bar.

“Oooh! That's gotta hurt.” I reacted.

Grillby put down his shot and cradled Sans' head with his hands. I was just close enough to make out Grillby's concerned mumbles to Sans.

“Ooooh nooo~ My sweet boy. Did you hurt yourself?”

Did he just say sweet boy?! Oh my god. Grillby is a Daddy. Oh shit. I'm doomed. We really should get out of here. Besides, I don't want to have to watch Sans get all that attention from Grillby instead of me!

“Grillby. I'm fine. Let go of me. What is this?”

Sans batted Grillby's hands away and looked at the abandoned shot. He smelled it first, and immediately recoiled from the strong scent. Then he tasted a bit.

“Fuck! Grillbz! What is this!?”

Grillby was not aware of Sans' question. Still concerned about his slightly injured chin. Without a word, Grillby put one hand on Sans' cheek and the other on his chin. He carefully tilted Sans' head up to inspect him.

“A-aah! Knock it off.”

“Haha! What the hell happened to him Sans?” I laughed.

“Never let Grillby get drunk. He's gonna- ugggh. Do thith all night.” As Sans spoke Grillby's head lolled to the side as he pinched both Sans' cheeks and smiled at him. “And he usually keeps trying to drink if you ever take your eyes off him.”

“I don't see anything wrong with it. Heheh. Where's my phone?”

“Don't. Fucking. Think about it.”

“Hmmm. I guess you look okay. You don't sound hurt at least.” Grillby slurred as he pet the side of Sans' head.

“Ahhh. Stoop.” Sans tried to bat away Grillby's hand, but it only made the fire monster more determined.

“You're a bad boy.” Grillby reprimanded.

Sans' already big but narrow eyes suddenly became round and wide. “D-don't say that out loud!” He looked around anxiously to see if anyone heard.

The whole bar was already laughing. I actually felt bad for him. He seemed to be pretty humiliated by Grillby's sudden urge to dote on him. Sans hopped off his stool and went around the bar to where Grillby was. He started cleaning up the shots so I helped him by pushing them forward. After all, he was pretty short. I didn't want him to embarrass himself more.

“Awwww Saaaans. Why are you cleaning up? I wanted to drink with you.”

“You can drink when you learn how to handle your alcohol.”

“I think you're just embarrassed. Hmm~ I can fix that.”

Grillby came out from behind the bar and started insisting that everyone leave. Pretty much everyone agreed, with best wishes for Sans to “get some”.

“Y/N. Why are you leaviiing?” Grillby whined.

“Haha. I thought you wanted everyone to leave.”

“Well… mmn. I'm sure Sans won't mind if you stay.”
