Frisk decides they don't want there to be any resets, ever again. Thankfully, Sans is there to help.

The Sun felt strange against Sans' body. Something about it felt familiar like he'd been up here before, which, in all likelihood, he had. He'd be damned if he could remember it, though. He sat on the crest of a hill some ways away from the village where all the other Monsters had set up after escaping the Underground. Sans could see it in the distance, sitting calm and peaceful, without a care in the world. They had no idea that, at any moment, all of this could be reset. The thought disturbed him more than he could describe.

Still, though he thought as he cracked open a soda, the weather's beautiful today. Why not take a load off? Sans sat watching the day go by, so absorbed in his own thoughts that he didn't even notice someone creeping up on him until they tapped him on the shoulder. Sans leapt up and around, almost whipping out an attack until he saw who had come to see him.

"oh, hey frisk, it's just you," Sans with, relieved. "what's up? don't you have something better to do than hanging out with me?"

As always, Frisk was silent. Sans almost admired their commitment to stoicism. No matter what happened, they always seemed nonplussed with it all. Almost as if they could reset any mistake they made with a snap of their fingers or something. They just sat down next to Sans and patted for him to sit down beside them.

Sans sighed, and did as they suggested. "so, i wasn't expecting you, but now that you're here, can i ask you something?"

Frisk nodded, still looking up at him.

"you could reset all of this if you wanted to, right?" Sans said, looking down at the village of Monsters. "don't bother asking how i figured it out - i just want to know the truth. how can i know you're not just gonna take all of this away again?"

Unbeknownst to Sans, this was actually the thing Frisk had come to talk about. Sans had a point - how could he trust them to not reset things again? Moreover, how could Frisk trust themselves to not reset things once they become boring? The temptation to reset would always be there. Already, they'd felt the drive to go back and relive all those fun adventures. One day, they'd definitely give in to those desires.

Well, unless this plan worked, that was.

They got on Sans' lap and gestured for him to open his mouth. Sans just looked baffled. "hey, what's going on? what's all this about?" He felt that this was something new, something Frisk or whoever else had never tried before.

Frisk gestured for Sans to open his mouth, and then patted the skeleton's solid body. They made a heart gesture with their hands and then pantomimed that heart melting away.

Sans looked confused, thinking that he must be missing something for sure. There's no way they were actually suggesting that he eat them, right? Yet, as Frisk reached up and pulled Sans' mouth open, he realized that was exactly what was happening. For a few seconds, he wasn't sure what to do. "hey, uh, are you sure about this?"

"...alright, fine," Sans said after a second of hesitation, grasping Frisk's lower body. "you wanna go in so badly, well, down you go."

His firm hands thrust upwards, sending the top of Frisk's body up into his mouth. Sans felt Frisk filling his mouth, first with their head, and then with their chest as he shoved them in further, hands shoveling them down hungrily. Soon, he'd fit all of them into his mouth except for their slim legs, which he slurped down in short order, leaving nothing of the human on the outside world.

Sans felt them wriggling against his tongue, and he took a minute to savor the moment. The human who'd caused him so much trouble was finally all his. He ran his tongue over their body, feeling how they were beginning to be worked down his throat. Sans smirked as he tasted their earthly flavor, thinking briefly of just how much weight this human would give him in the end.

He began swallowing Frisk down, his throat clutching around them as they were pulled downwards. A thick bulge appeared on Sans' throat as he swallowed, his body attempting to gulp down the entire human at once. The bulge increased in size as more of Frisk was swallowed down, moving from the skeleton's mouth to his tight, constricting throat.

They were definitely the biggest meal that he'd ever had. Sans used his tongue to shove Frisk further down, feeling then slither further and further down his gullet. So close to being his. The skeleton tossed his head back, and let gravity do all the hard work. Immediately, Frisk's descent was greatly hastened, and he felt them slide entirely down from his mouth into his throat.

Sans swallowed heavily, feeling his throat clench and tighten around Frisk, grappling them towards his waiting, starving belly. He traced their final downfall with a finger, feeling as they slipped finally from his throat. The bulge on his gullet vanished as the human was pulled once and for all into Sans' stomach.

Sans collapsed back on the hill, letting out a long, relieved sigh and a mighty belch as he felt Frisk settle down in his belly. Right away, his belly got to work digesting Frisk. Sans' gut let out a loud, prolonged gurgle as his stomach sloshed around its latest meal. He patted his round gut, feeling wonderfully full and satisfied. "woah," said Sans, "that was way more fun than i'd thought it be."


Sans felt Frisk wriggling around in his stomach. He wasn't too sure what was happening there, maybe they were just trying to get comfortable or something? "heh, yeah, get comfortable in there. cause you ain't leaving, that's for sure," Sans said, with a level of satisfaction that surprised him. His gut only responded with a heavy churn. Their form was still solid, but judging by the sounds Sans' gut was making, they definitely wouldn't be for long.


He gave his belly a firm slap, wondering just how much weight he'd get out of this, if Frisk ended up going through with it that was. Muffet had said something once about how large she'd become after eating a human. Perhaps it's the same here…? If he hadn't spent so long afraid of this human resetting things, Sans would almost feel bad for thinking that way.


Sans let out a burp, and felt his gut clench and soften around Frisk. Well, before he got to all of that fun, first he had to finish digesting them to begin with. "hope you like what you're feelin' buddy," he said, with a pat of his belly. "i definitely am!"


Frisk felt the warm walls of Sans's belly contract and tighten around them. Already, the skeleton's body was getting to work digesting theirs. Frisk felt themselves growing weaker as the gut sloshed and churned around them, his juices beginning to work them away into just fat on his body. It would be better this way, they told themselves. This time, there would truly be no more resets. This was the thought that the human hung onto as Sans' belly clenched around them, and properly got to work breaking them down.


Sans pressed his hands into his belly, kneading his gut as he felt Frisk start to soften under his hands. Already, his jacket and shorts felt tighter on him, as if that human had already begun to fatten him up. Sans leaned all the way forward, and came to a rest on top of his belly. He pushed his hands into the sides of his stomach, feeling it churn hungrily as the human inside began to break down. "wow, sounds like you're already in the thick of it, huh?" Sans said with a chuckle.


If Frisk said something in response to this, it was impossible to hear it. Sans' insides were well and truly growling now, consuming everything inside of them. He squished his belly, feeling his hands able to sink in deeper, meeting less resistance with every passing moment. Sans still felt vague kicks and movements coming from within his tummy, but they seemed to be growing weaker.


Shameful saliva dripped from Sans' mouth as he felt Frisk melt away within him, their Soul being absorbed and churned into just more weight on his body. He felt his pants continually stretch with new weight, pushing further and further outwards, until they finally started to rip from how big- boned Sans was getting.

Frisk felt themselves being absorbed, their very being and Soul becoming part of Sans and his increasingly-large body. In spite of themselves, their body kicked and struggled. But they swallowed whatever fear they had left. If this saved their friends and the Underworld from being reset, it would all be worth it.

"woah, no struggling now," Sans said with a smirk. "we had a deal! besides, i think you look a lot better this way." He gave his ass a smack, watching how large it'd become with a good deal of pleasure.

With a clench, Sans felt his gut suddenly shrink as a good deal of Frisk was pumped away. His belly let out a loud glooorp as Frisk started being properly worked into nothing more than just thick sludge in Sans' gut, destined only to be pumped away into his body and make him that much larger.

Sans gripped his belly again, his jacket growing ever more ill-fitted to his increasingly fat form. He could tell that his entire body was getting a makeover from all of this human weight. His thighs and ass were growing round and wide - something he wasn't looking forward to having to explain to Toriel and the others. And his stomach, as expected, seemed larger than ever.

"ahh, feels like there's less of you in there with every passing moment," Sans grinned with a spank of his belly. Before he went through with this though, wouldn't it be for the best to make sure it's what Frisk really wanted? "sure you don't wanna like, travel back in time or something? cause this is the last time i'm gonna ask."

His belly only gurgled in response as, with one final slosh, what was left of Frisk was fully churned up. Now there was nothing left but to fully absorb their body and soul into his own body, forever sealing their fate. Sans' body began to swiftly grow larger and wider, absorbing all of that thickening human into his own form.

Sans' guts continued pumping and gurgling, though the skeleton's attention was swiftly drawn elsewhere. His pants were, in short order, ripped apart entirely, his rear and thighs growing far too large for them to handle. He had to spread his jacket all the way open to avoid it being ripped apart by his rapidly-expanding belly. Already he could hear the insistent questions as to where Frisk had gone, and as to where he'd gotten all this new weight. Well, for the latter, he could always just blame Papyrus' cooking.

The skeleton stood up, struggling to maintain his balance with all of that new weight he had. He slapped his belly and belched, sending up a scrap of Frisk's shirt. Sans couldn't help but chuckle. "heh, seems things finally caught up with you, huh?"

His Alphys-sized belly didn't say anything in response. He admired his new big bones for a minute. Everything from his thighs, which had swelled to being as wide as a monster's sword was long, to his wobbly ass, which was big enough now to serve as its own bench. He gave his thighs an admirable smack, examining that they'd gotten far bigger than he ever imagined they would be - thick enough for him to bust a skull between, certainly. There was a skeleton joke in there, somewhere, but Sans didn't feel like searching for it.

He reached around and felt up his ass, each cheek large as the belly on a regular monster. Sans was a bit disappointed that his signature shorts had been ruined by all of that extra weight, but eh, in the grand scheme of things, it didn't matter much, did it?

No, he figured, it didn't. He felt his genuinely huge belly slosh and shake with weight, and felt a comfort knowing that he'd fully absorbed all of Frisk. Now there wouldn't be any more resets, and he could finally live out his days in peace along with his friends, knowing that it wouldn't be taken away from them this time.

"well," Sans said, turning back towards the village, "thanks for that, frisk. i won't let it go to waste."
