The look Sans was giving them was dark and controlling, uncompromising. They didn’t exactly want him to feel, uh, harsh towards them, but also, mmm.

He reached out and grabbed the front of their pants roughly, then growled, “get ready to heal.”

With no further warning, another swarm of bones appeared. These weren’t as carefully directed, though. He didn’t even look where he was aiming, just holding Frisk’s gaze as though daring them to object to this sort of treatment.

The shards ripped through flesh and pants alike, but Frisk had learned how to take these hits, pulling their power to corrode their soul, not their flesh. It burned and ached, but he was just taking what he wanted from them, and they couldn’t help but tremble. More shameful sounds of need escaped them.

As they were rendered naked, they reached out and took hold of the save point, feeling the power flood them, their body rapidly healing from the assault.

He looked them over possessively and they took a sharp breath. A bony hand reached out and raked down their body, pushing them back a little for easier access to their pussy. They’d gotten it waxed and hoped he preferred it that way. He didn’t comment and just toyed with them.

It was rough and almost uncaring, his motion, as he flicked their clit and ran a finger around their entrance. They gasped and wriggled at his touch. He lingered there for a moment, grinning at their hopeful face, but pulled away without letting them feel him inside.

He looked contemplative for a moment as he flicked their clit again, then grabbed their waist and roughly forced them over onto their belly. He squeezed their ass, then slapped it, chuckling to himself in amusement. Probably at the sound they made from the slap… they flushed again. He spread their cheeks and their flush deepened. Wait, was he into… uh…

A stinging pain filled them - had he just flicked his finger at their asshole? The hell, Sans! He continued to chuckle, a steady sound of amusement. He grabbed them and flipped them back over onto their back, their legs ending up awkwardly spread before them.

“time to show me,” he said, his voice still low and dark. “show me how you like to be touched and don’t let yourself cum. i want you lost to desire. i want you to know that you’ll only cum when i feel like making you.”

“As you wish,” they said, shivering at the sound of his command.

They knelt before him, ready to worship him in any way he desired. Their embarrassment and pleasure were the tribute he requested, and so with one hand, they rubbed at their clit, and the other clawed down from their neck to their breasts.

“you really like the pain, don’t you?” he asked.

“Y-yes,” they admitted, breathless.

They were getting close, so they moved from stroking their clit to massaging over their pussy, especially around where they were achingly empty. They'd never figured out an angle that felt satisfying with fingering themself, and so they remained agonizingly empty.

“I know you don’t want to hurt me, not as much as I want, so I’m trying not to… not to ask you to do things you don’t want to do,” they said.

“i’m kinda frustrated with you right now,” he said, and they flinched. “maybe hurting you would be more fun than usual - as long as you’re getting off on it.”

Him saying that… oh god, they were too close. They tore their hand from their pussy and tried to shove away the feelings. That was too close, they almost came. Touching themself while he was saying things like this, while they’d been broiling all day and all night… it was too much, they couldn’t handle this!

But once that wave passed, there was something more important.

“I don’t want you frustrated with me,” they said meekly.

“you say that,” he said. “but you’re supposed to obey me and you were trying to defy me, weren’t you?”

As he started to speak, he ran his hand through their hair gently, then suddenly gripped it and pulled them into him. His presence, even through the shirt and shorts, was a pressure on their mind and body, and they couldn’t help but squirm.

“I wasn’t, not really,” they protested, their face against his neck.

He wanted them to suffer, to writhe in need, and they felt their pussy could take a little more again, so they shoved a hand down. And… and… they were lined up, they could feel him, his erection pressing against their hand through his shorts. They wanted… they needed… but they had to be careful…

But they really had to focus, to explain this to him.

“You wanted me to not die, you wanted things that matched my tastes, you wanted me to hurt but only within the extent I could enjoy, you wanted my body to not be seriously hurt at all,” they forced out. “You just didn’t have enough faith in me. You didn’t trust me to give you what you wanted. I am skilled enough, Sans, to do this and have it all.”

“it’s hard to believe you could really enjoy that sort of pain,” he said.

Doubt, again, damn it.

“Test it,” they said, determination blazing as they pulled back just enough to give him a challenging look. “Hurt me, Sans.”

“tell me, frisk,” he said with a grin. “you keep pulling your hand away from yourself. how close are you to cumming?”

“S-so close,” they admitted, pressing into his body harder. “I keep getting so close, too close, but I can suffer more for you, this is so good…”

His hand moved and then they felt a sharp pleasure/pain from their nipple. No, no, too close, damn it! They shuddered against him, holding back their orgasm again with a cry.

“you almost came from that, didn’t you?” he asked.

“Y-yes, almost… god, Sans…” they whimpered.

“i could make you cum just like this, couldn’t i?” he said. “squirming against me while i hurt you.”

They shuddered again, they couldn’t handle this, they were going insane. They gripped his shirt desperately.

“Yes,” they whispered, begging him in their mind to make it stop, to make them cum.

“but you don’t get to cum yet, do you?” he asked and they whimpered desperately. “so i can’t try hurting you right now, because then you’d get off and i wouldn’t get to see you like this.”

He chuckled to himself again as they writhed and whimpered and begged him with their eyes.

“i want you to know how hot i find this,” he told them, setting off another inferno within them. “it’s driving me insane, watching you squirm, hearing those sounds you’re making, feeling you move against me like this. i don’t want this to end, so i’m dragging it out, even though i can’t handle much more myself. i’m pretty close to cracking, and as soon as i do, i’m going to start taking your mouth.”

Frisk had died and gone to heaven. There was no sanity in them now, not on hearing this. He wanted them, he was being driven insane, his control was on the edge of breaking, and when it did, they would taste him and feel him get off with their mouth, and they still wouldn’t be able to cum, and…

There was only fire in them, and need, and desperation, and devotion, and always, always, determination.

With a casual motion, he took off his jacket, throwing it across the room. They suddenly realized they’d never actually seen his sides or arms before and he looked somehow… different. It was the way he held himself. Like his shoulders almost wanted to hunch in. Maybe that there was a nervousness to him.

The impression passed quickly, and he resumed looking like the domineering Sans that they’d been kneeling before today. He gazed at their body with desire and all speculations on his momentary vulnerability burned away. They wanted him so badly.

They pressed up against his body again. He hadn’t objected when they’d felt him while touching themself, but maybe grabbing for him would be too much. Maybe… maybe they could just press against his erection, grind their needy pussy against it, but they couldn’t cum, they couldn’t, they were going to die…

With an odd grin, he suddenly lay down onto his back and pulled them on top. They straddled him, feeling his bulge right where it needed to go, and they couldn’t touch themself, they couldn’t. With him like this, they were too close, again, but they could suffer more for him, they could claw at themself and whimper and writhe.

He reached down and suddenly they felt something that wasn’t cloth. A tingling pressure of magic pressed against them, right against their clit, and a prickle of sensation ran over their entire body. Oh. Oh, was he going to take them now? He was wrapped in their folds, wet with their juices, but not inside, they wanted him, was he about to…?

His hands gripped their waist for a moment and they gasped. But instead of driving into them, his left eye shone blue and orange, just as it had that fateful day, and they felt his magic hold them, pull at them. They didn’t resist and their body slammed into the wall by the bed with a thud. They fell, landing on their hands and knees, and suddenly he was holding their hair tightly, too tightly, they couldn’t move.

He pulled them over to him again and their mouth was right over…

They didn’t have time to admire the glowing blue appendage, its sleek shape, its size, before he thrust it into their mouth.

Right, he’d said that he’d take their mouth once he started to lose control, and so this meant he desired them so much that he…

They shuddered around his cock, loving at it with their tongue, feeling the ridges and head as he forced them to take it. It was hitting the back of their throat, too large for them to take, but they needed a moment to adjust. It felt good, it felt amazing, being used like this, knowing they were a thing for his pleasure, feeling his pleasure against their tongue, pressing against their throat. They heard him groan and breathe harder as he took his pleasure from them.

This was so good.

His cock was amazing, and felt so strange. They’d sucked two guys off before, but Sans was incredibly different. No saltiness - he still tasted like death and magic, but also like lust and pleasure. Again, they didn’t exactly understand how “lust and pleasure” could be a taste, but apparently it was. No random hairs, or smooth skin. It was a sleek thing of magic that was an experience all its own, one for which the word “texture” didn’t even seem to make sense. It was uncompromisingly hard in some ways, feeling like he could drive past even if they tried to slow him down. Soft in others, as the surface seemed as semi-real as the rest of his pseudo-flesh.

It felt like power, and magic, and inevitability, and lust, and death, and they were in love.

They managed to get a handle on things. He wasn’t moving too fast, giving them a chance to breathe between thrusts, if only just. But that meant that they could try their secret weapon. Okay, not secret, but they were sure this would be great.

They focused, pulling on their training, their practice, their memory. They needed to get this right the first time. He wanted to feel them around his cock, he just needed to have the ability to go deeper. And they knew how to do that.

Around his cock, with their tongue and lips, they maintained their defense, maintained their presence, their ability to pleasure him. But in the back of their throat, they focused on the other sensation. A feeling like death, which they knew intimately. A feeling of absolute vulnerability, of absolute surrender, of complete acceptance, of sacrifice and invitation. In that specific place, their soul wasn’t just available, it lay on the altar in tribute to their god.

His next thrust didn’t end at their throat, but pressed beyond, burning and consuming as it drained out their soul. But they felt the desire in it, they felt the sheer presence of magic that was pure desire, pure lust, pure pleasure - that was its purpose, and they felt it within them.

Oh, this was hard. They had to be careful, to keep the pace sustainable, to ensure they wouldn’t die too quickly. He needed to cum first. And they had to stay focused on not cumming themself, which was maybe the harder task.

The sound he made as he bottomed out was something they wanted to remember forever. A gutteral noise, of need, of pleasure, of desire, a thing of madness. He shifted and they discovered he had been intentionally kind to them as his grip went from a pleasantly gentle stinging to true pain, the bones of his hands digging into their scalp. With both hands he forced them, and they focused their entire will on maintaining that effect.

With each thrust, another measure of their soul was stolen away, another measure closer to death. But only a little, and less each time, as they tightened the connection to a small flow. They could maintain this for long enough. They had to brace themself, to be ready, because it would probably be a hell of a lot more intense when he came.

God, they wanted to feel that.

He thickened and grew still larger as he thrust into their mouth, so much so they felt like their jaw was practically going to be unhinged, and their soul was burning even deeper. But they didn’t care, it was so good. And all the power of the sensations magnified with its size - the death, magic, lust, and pleasure alike.

With another gutteral groan that nearly pushed them over the edge, he came. His cock was buried to the hilt and swelled with power, releasing it in a wave of magic directly into their soul. It burned all that it touched, but also carried with it his pleasure…

And that was too much. They felt their own pleasure start to peak in response, but they couldn’t, they weren’t allowed to cum, they threw the walls of their defenses up hard, blocking off the magic absolutely and clamped down in their mind on their own sensations. He was physically “ejected” from their soul, from their body, and they had to pull away. They couldn’t breathe, they had to stop the pleasure from cresting.

Agonizingly, it settled down into an ember of desperate need, but they’d succeeded, they hadn’t come, they’d been good. With a gasp, they reached out to the save point, drawing forth the strength they needed to restore themself.

They’d succeeded. Barely. But they hadn’t died, and while if they’d tried to take it, it’d have been… really really close, they honestly thought they could handle it. They’d discovered on that darkest day that no matter how thoroughly his corrosive magic poisoned them, it could never fully kill them, and so they were almost completely sure they’d have survived. By the skin of their teeth, maybe, but that was really not that important to Frisk. To Sans… probably, but they didn’t have to mention that part.

Besides, they thought, as they grinned at his limp form with a dazed, happy expression on his face, he’d clearly enjoyed himself. They gazed at him happily, memorizing how he looked in this incredible moment. Yeah, they were still on fire and were absolutely not done, but this? This was precious.

They laid down next to him and snuggled close. Maybe it was presumptuous, but surely, after all that, it would be allowed. They laid their head on his oddly soft chest - they still couldn’t fully get over a skeleton having a soft and squishy chest and stomach - and sighed happily. They couldn’t quite feel, uh, content with this much fire in their veins, they couldn’t quite manage to restrain their squirming completely, but it was still nice.

“S-sorry,” they whispered from beside him. “For pulling away like that.”

“you did the right thing,” he said, still with a dopey expression on his face. “i don’t want you hurt.”

“H-hurt?” they asked, confused. “No, Sans, that’s not what happened.”

“it isn’t?” he asked, looking over at them.

Meeting his gaze in his bed like this was really not easy at the moment. A quivering breath escaped them but they managed to stay focused. They had to make sure he understood.

“No, not even close,” they said. “Okay, maybe that’s not true. It was probably closer than you’d like. Er. If I’d taken everything, definitely closer. But I could have taken it all.”

Uh, they needed to get off that point. They tried to corral their thoughts again.

“No, the problem was I lost control. I started to cum, and I’m not allowed, I had to pull away, else I’d be bad, and I realized after that you might have preferred for me to cum then. I should have realized ahead of time and asked what you’d prefer.”

He looked amused and shifted, wrapping his arm around them and pulling them tightly to his chest. It was such a strange feeling. His chest was bizarrely soft, but his arm was exactly what they’d expect a skeleton arm to feel like.

Being with Sans was weird, but they wouldn’t trade it for anything.

Being still was still not happening, though.

“you were good,” he said, and they felt a deep wave of satisfaction at his praise. “you did just as you should have.”

They squirmed happily and made some pleased noises as they snuggled into his side.

“you know, i’m actually a little capable of thinking again,” he said and they grinned.

“Mmm, that’s kind of a shame,” they murmured and started stroking his chest. “It was so hot, what you said, that I was making you lose control.”

He let out a soft sound, almost a sigh, sounding so content. This was so good, in a very different way than the fire in their blood demanded, but still so good. They kinda wished they had cum so they could enjoy it without being quite as distracted, but it was still amazing.

His hand was stroking up and down their back. It wasn’t teasing, or erotic, or anything - it just seemed affectionate. Appreciative.

He was silent and seemed so at peace, so relaxed. Slowly, they settled. Their trembling eased as they embraced the soft sweetness of this moment.

“this is nice,” he said and they hummed in agreement. “sorry for, uh, being kind of cruel to you.”

They giggled and poked him affectionately. That was the most ridiculous thing.

“I can’t cum now, but I’m going to be cumming to that memory so much later,” they admitted breathlessly. “It’s going to be so hard, holding myself back from whatever you’re going to do next.”

“you do seem to have cooled down quite a bit, though,” he said.

“I’m no longer on the edge, but that means I can take more without pulling back,” they murmured, wriggling against him with delight at a thought. “Maybe you could test it, now, how much pain I can take before it becomes unpleasant, now that I’m not on the edge of cumming?”

“you want that, don’t you?” he asked. “you want me to hurt you.”

Even just him saying that… damn it, they were trying not to ruin the serene peace he was feeling, but the fire was not satisfied with this situation.

“It feels soooo good,” they said in a moan. “I didn’t want to admit it before, it’s still so embarrassing, I shouldn’t be like this, but it’s so good…”

“it’s kinda funny,” he said with a little laugh. They felt a sharp pinch on their ass and yiped in shock. He laughed harder and then continued. “i was trying so hard to figure out what your tastes were. what you liked, what you wanted, because i didn’t want to just take advantage of you, i didn’t want to hurt you. but you’re a slutty little masochist who wants to be hurt and taken advantage of. it’s not just your devotion, it’s your fetish.”

Squeak. This was mortifying. It was true wasn’t it, they were a slutty little masochist who’d dragged him into their perversions and this was so bad… but so fucking hot, even just hearing him say it…

They couldn’t face him, couldn’t face this, couldn’t face the melting in their insides at the realization… they buried their face in his side and just hid from everything.

Not that they were safe there. Or anywhere. They’d realized that first day they presented their plan to him that he would embarrass them and, as long as they didn’t give up, there was no escape. Meaning there could never be an escape.

“tell me if i’m right,” he said.

Yep. No escape.

“Y-yes,” they admitted directly to his ribs.

God this was embarrassing.

“you get off on the idea of being used,” he continued. “whether i’m using you directly, or what you’d said before, giving you to someone else for their use.”

No, no, no, no… They had said that, hadn’t they? They hadn’t thought about what it meant, but it was so true. They couldn’t speak and buried their face even deeper into his side. They felt a poke.

“God, yes, Sans,” they whimpered, embarrassed beyond anything they’d ever felt.

“and does it always turn you on when i give you orders? even for non sexual things?” he asked, continuing to softly stroke their back and ass. It felt so nice.

“No, but, it always feels really good,” they said, resting their face on his chest again, but not yet able to meet his eyes. “It feels so… satisfying. Like being given a hug and being told that everything is going to be okay. But, um, if I’m already horny when you give an order, then yeah, it turns me on more. Even if it’s not sexual.”

“so you’re saying, if you’re turned on and i order you to… i dunno, swap out a lightbulb, it’d actually turn you on more?” he asked.

“The lightbulb part, no,” they said. “But the sound of your voice when you order me to do it, the pleasure of knowing I’m of use to you, the pleasure of knowing you want me for something… yes, it would.”

“because, on pretty much every level, you just want to be mine,” he said, his tone thoughtful.

Wait. No. This didn’t have that same sound of despair, exasperation, and bewilderment that had always underlaid those words. He… he wasn’t actually understanding, was he?

Either way, they nodded, feeling a surge of hope.

“for my joy, my happiness, my use, my pleasure - sexually and otherwise. you really, actually desire that,” he said, still sounding thoughtful and understanding, still sounding like he wasn’t just speaking words of condemnation. Their trembling, tentative hope grew stronger. “and not just out of a place of brokenness and a desperate need to feel like your life has meaning, but also out of… more than that. even as an outright fetish.”

Was that the key to helping him understand? He’d thought of this desire as a negative thing that chained them, not a positive thing that eagerly spurred them on, and this perspective finally let it flip?

A strange sort of happy sound, half laugh and half contented sigh, slipped from them as they gazed at him with real hope. The way he looked at them now, with curiosity and appreciation, not guilt and faint pity like he usually did when he spoke of their devotion to him…

Their heart was soaring.

He touched their face softly, a gesture of appreciation and loving gentleness, and his eyes were smiling with equal tenderness. The spark in his eyes shifted as his attention drifted downwards and he looked at their body. The hand that had stroked their face shifted to a finger beginning to trail down.

“i want to explore your body,” he said, his finger tracing past their neck to their chest. “i want to see what you enjoy. you’re going to tell me what you’re enjoying, even if it’s embarrassing, even if you’re afraid you’ll drive me away.”

Their fire approved, but… he needed to understand.

“Please, Sans,” they whimpered. “You… you have to want it, you have to only do things you want, if I’m left wondering, then I won’t… then it won’t be that good for me, but if I know it’s what you want…”

He grabbed their breast and his thumb scraped over their nipple, a harsh sensation that made them squeak.

“i’m not a sadist,” he said.

Seriously? Who did he think he was fooling? Maybe himself, but not Frisk. They were giving him a disbelieving, amused grin.

“well, not exactly,” he amended and their grin widened. “but i love reactions, frisk. you know that. i don’t want to hurt you, but i do want the sounds you make when i hurt you.”

He pinched their nipple and they squealed, wriggling against him.

“i don’t want you to actually suffer, but the sight of your desperation when i’m tormenting you and not letting you cum, leaving you insane with need… i like that,” he said. “i guess it’s a difficult balance, between being a sadist and not.”

Okay, this was difficult, they were still on fire, and his finger was still trailing downwards, and damn it…

“I think you kind of are,” they said, squirming. “You don’t want it to be so much that I’m driven away, that I’m actually having a bad experience, but you want me overwhelmed to the point of breaking.”

He totally was. He even outright said he wanted to torment them, like seriously, how in denial could a guy be? But they couldn’t quite accuse him of it. Or maybe they should. Maybe he needed to know this about himself.

“you got me,” he said, his finger reaching their needy pussy, but sadistically - whether or not he admitted it - refusing to touch them in a satisfying way, just touching his finger to their clit and holding it there. “so i guess what i’m saying is, i want to know what will give me the hottest reactions. what tools will drive you to the edge of insanity, what i could do that will break your will and leave you actually begging me to make you cum. for my sake, because that’s what i want to do.”

How the fuck did he not realize he was a god damned sadist. What did they ever do to deserve this?

No, stupid question.

Those flailings in their mind were distant, though, as their body had reacted to this all on its own. Because, as awful as that sounded, it was also incredibly hot and they were going to burst into flames and just die and damn it all. It was so awful, so hot, so terrible, they were going to suffer so horribly, and he would drive them insane, and they wanted to cum so goddamned badly and they were going to teach him how to torment them even more so there would never be an escape and…

Their hands were gripping his shirt, their mouth was half open as if ready for his cock to be inserted, they gazed at him with wild need and they were just doomed.

“H-hurt me,” they said, and they didn’t even know if they were begging or telling him what he wanted to know, and it didn’t even matter, because there was no escape. “Take what you want of me, force me to do things, do things without warning, without asking, so I don’t know what’s going to happen. T-that’s what turns me on more than anything else, Sans, it’s so… so goddamn hot…”

“that much, i’ve figured out,” he said, his voice thick with amusement and heat. “let’s find out more.”

He leaned over on top of them and paused, looking over their whole body. They felt no shame at his gaze, they wanted him to desire them, to touch them, to make them fucking cum, god damn it.

After a moment of just watching them squirm, the pervert, he leaned his head close to their breasts and a line of blue darted out. Thinner than before, the faintly blue glowing tendril was almost whiplike as it lashed against their nipple. They hadn’t expected that, and they shrieked in surprise and pleasure at the feeling. It wasn’t even remotely tongue-like, what the hell!

What else could he shape it to be like?

Hnng, those thoughts were not helping.

His tongue wrapped around their nipple and squeezed it, but then shifted. It had been sort of snake-like - warm, firm, but with a little bit of give, and very smooth. But it grew harsh bumps of uneven size and it ripped over their skin mercilessly, sending waves of sensation that magically seemed to make their way directly to their horribly neglected clit and they were going to lose their goddamned mind.

“Fucking hell, that’s hot,” they whimpered. “B-be careful, I can probably cum from that if you keep it up.”

They wanted to cum so badly, but it’d be at his will, not by accident. They felt his tongue pause in its assault after they spoke. It quivered and shifted its texture and they grinned. That had really turned him on, hearing that, hadn’t it?

And, now that they thought of it, they weren’t completely helpless, were they? If he put his pseudo-flesh - his coherent magic that directly connected with his own soul, with his core - in immediate contact with their flesh… they had options, didn’t they?

Without thinking it through, they chased the impulse, and lay bare their defenses on their breast. His tongue slipped through and he reeled back in surprise as they giggled as his expression.

The pain of it was so good, feeling the burning directly on their nipple like that, feeling the raw, pure magic inside of them, feeling their soul pour into him. That was god damned addictive, is what it was. It wasn’t burningly hostile like his attacks were, didn’t hurt in the same way at all, but was so incredibly compelling.

The pleasure pushed them near the edge again. They were practically bubble wrap, ready to pop at any and every provocation. Their body was just so done with this nonsense, so ready to cum, so eager to cum.

“That was so good, Sans,” Frisk moaned, writhing and arcing upwards to press into his body.

“this is supposed to be about exploring you, frisk, not you doing things that we already know you like,” Sans chided.

Oh. Right. Whoops.

“maybe i should try pushing your masochism a little,” he said with a dark grin that sent shivers up their spine. “not sure it counts as punishment, all things considered, but we can pretend.”

He leaned back and grabbed them, shoving them over to the save point with a chuckle. With a sheepish grin, they saved and then looked at him.

“What are you going to do to me?” they asked nervously, biting their lip as they gazed at him.

“in the spirit of punishment,” he said, letting his eyes go black and making them squirm with nervous anticipation. “i am going to hurt you. i want to know exactly how it feels.”

He was actually going to outright hurt them on purpose, for their pleasure. Not just a little tweak of their nipple, but… but what? It was so wrong that this was so hot, this was terrible, they shouldn’t react like this, but damn it, and he could see it, he could see how much they wanted this, what a slutty little masochist they were and it was going to feel good and he’d know it, because they’d have to tell him how it felt and…

A bone appeared, but not one of the little shards he’d used to wreck their clothes. It was a full sized attack, like the ones that had killed them so many, many times on that dark day. Sharp edged and violent, they could feel the malicious intent behind its craftsmanship from here. This was a real attack, the fuck.

It was so wrong that this was so hot. But also, also, it meant he’d believed them, that he was starting to understand. Their skin warmed all over, feeling utterly naked before him for an entirely different reason as they quivered in anticipation.

“You’re… you’re really going to…” they asked, breathless, feeling stunned.

“shouldn’t we find out what your limits are?” he asked, his tone amused as he playfully balanced the bone on his finger.

Hnng. That wouldn’t be anywhere close to their limits, which was embarrassing and made them blush more. But… but the fact that he was trying, that he was pushing past his own comfort zone for their sake… in a twisted sort of way, this was incredibly sweet and they had no idea how to even begin to react to this.

He gestured for them to come closer and when they did, he casually began to scrape the edge of the bone over their chest and stomach. They felt the faint corrosion take them with every impact, but their skin was fine - they felt another flush of appreciation at the realization that he’d tempered his magic to avoid their flesh, striking only at their life instead. It was hot, way more than it had any right to be, this was so wrong, and what was he going to do?

They could only squirm and gaze at him and wonder and endure anything he wanted to do to them…

His left hand darted forward and grabbed them by the throat tightly, too tightly, they could barely breathe and they gasped and squirmed, helpless before his assault. His right hand moved next and a sharp, burning, cleansing wave of pain burst from their shoulder and wove through their body and it was so good and…

Oh fuck, they were starting to…

They cried out sharply and shook, trying to keep focus, yelling, “No, Sans, stop!”

The bone vanished immediately, he let go of their throat, the pain started to ease, but it still burned in their soul, and they tried so hard to clamp down on the sensations, they were so close to…

“that was…? i’m so sorry, frisk, i thought-” he started to say, but no, no, they couldn’t let him be wrong like that, and they threw themself at him, clapping a hand over his mouth as they desperately tried to keep their body from falling over the edge.

God, he felt good, and they felt like they only had the barest tatters of control, they were still right on the edge, they were going to explode, they couldn’t breathe. Without choosing to, their body was pressed against him, writhing, but they couldn’t let themself cum. Not yet, not yet.

“You have to learn to trust me, Sans,” they said, burning and dying and still burning with his magic, it hadn’t faded. “That wasn’t too much pain… I almost came, I was starting to, and I’m not supposed to yet.”

They gazed at him desperately, wanting him to understand.

“I want you to make me cum, I need you to make me cum, but I want it to be on purpose, I want you to decide to do that to me, not by accident,” they continued, still quivering, still pouring their fire out into him. “And you wanted to know how it felt.”

He nodded, an odd look of… surprise, maybe, on his face. God, they were still basically on the edge, his magic was only now fading from its burning in their soul, like holy fuck. They would grind against him mindlessly, but then stop, they couldn’t cum, they couldn’t, they couldn’t…

“I felt you… you, Sans, your magic, your power, your intensity, your might, inside of my very being, helplessly run through by your strength,” they said, the words flowing strangely easily. “Pain isn’t important the way it used to be, it’s just intense, and if it’s on my body, it can be unpleasant, but in my soul, it’s now to the point that I just… it just doesn’t matter. It isn’t bad, it’s only overwhelming. And it was overwhelmingly you. Within me, burning me, flooding me with your soul’s magic, consuming me. The pain heightened it, blended with it, tore through my mind.”

“tell me,” he said. “how close was that to your real limits? of how much pain would be pleasurable to you.”

They could finally breathe again and gazed at him, wondering if they should tell him the extent of their insanity.

“I still think you don’t want to know,” they said.

“tell me anyway,” he said.

And how easy that made everything.

“I have no idea where my real limits are,” they said, freely and still too immersed in the fire to feel real embarrassment. “Not when it comes to magic damaging my soul, anyway - my limits with physical pain are, maybe not sane, but closer to it. Let’s just say that that little strike wasn’t anywhere close, and frankly, I don’t believe it’s possible for you to willingly approach them.”

Physically, yeah, it wouldn’t be all that difficult for him to reach their limits. Even the stabbing trials were decidedly unpleasant. But with magic? As hot as they were burning right now, they were pretty sure they’d cum if he pulled a blaster on them and killed them. Though they would die and reset too fast to finish cumming, so they'd just start to fall over the edge and then be right back to being so desperately needy and holy fuck that was hot and…

Damn it, they needed to not think about that right now, and really, how fucking insane were they?

But he didn’t look at them with revulsion, with disgust, with horror, or any other reaction they’d been afraid of. His smile turned gentle, for some reason, and even appreciative. They didn’t understand. Was he confused at how insane they were? They were confused at how insane they were, like, what the hell. But he didn’t look confused, either.

He looked… oddly happy. Relieved, maybe. They didn’t understand… was he actually okay with the depth of their masochism? They’d… they’d never expected that.

He reached out and touched their face again, gently brushing his fingers over their cheek and they smiled. It suddenly occurred to them… if he wasn’t capable of kissing, that might kind of be his equivalent.

“i’m glad you told me,” he said, continuing to brush his fingers softly on their face. “i’m going to tell you now how i want you to cum. you’re going to stay like this, needy and insane, for a little while longer.”

Being told exactly how they would cum… this was so fucking hot and also so weird in context with his affectionate smile, but that was also good, and they were just going to helplessly sit here and melt while they listened.

“i am going to resume exploring your body and you’re going to continue to stop me every time i am getting close to making you finish, showing me how to drive you even further into lust and madness.”

Yep, they were going to die. They would reach the limits of The Madness of Frisk and would discover that sheer horniness could, in fact, cause spontaneous human combustion.

“you’re going to resist giving in,” he continued gently, with that terrible, awful, deliciously erotic order, and they squirmed.

Fuck him to the depths of hell, they were doomed. Also literally fuck him, because mmm.

“i don’t want you to do the devotion thing, of clinging to your insane determination to get through this, because i do trust that you could resist anything that way, but that’s no fun,” he said, and they had to admit this was a fair point. And also appreciated his simple acceptance of it. “i want it to be more… natural than that. i want you to resist as much as you feel like you can, with your own natural limits. i want to see if i can break you and force you to beg, and as soon as you do, i’m going to take you and make you cum on my dick.”

He was going to make them complicit in their own torture, he was going to be getting off on their suffering, he was going to force them to actually try to resist it, he was going to break them, and only then… fucking hell…

They wanted to cum so badly they could cry and he loved that, the sadistic bastard.

And fuck them, so did they.

“of course,” he added in a casual tone. “it’s possible that i’ll crack first and i’ll just take you. i wonder if i’ll warn you first. maybe we’ll just have to play that by ear.”

So at any time, without warning, he might…

Another lash of fire took them, and they couldn’t breathe, damn it, Sans! They thought he wanted them to be sane, didn’t he always complain about how insane they were, this was so not right, but… fuck, they didn’t want him to stop. Their mind was a molten puddle of lava and nothing but a vessel for his sadistic pleasure and they were loving every moment of it.

“oh, one last thing,” he said, pulling them close and speaking into their ear. “it’s selfish, but i’m hoping you lose this little game.”

They couldn’t breathe, they couldn’t think, he wanted them broken from lust and begging, they could right now, but no, they were supposed to resist, but… fuck.

But one thought managed to stick around despite the inferno. The understanding of their plan that maybe he hadn’t fully comprehended, that they could be in a loop of having him inside of them, as they used their power to see if the connection was forming.

They wanted that, they would cum as much as they wanted to, they needed to remember that.

“I-I just have to remember to save right before,” they said, trembling.

He laughed lightly in their ear.

“i love that about you, frisk,” he said.

The fire was instantly cleared to make room for something far more fundamental to their soul. It still burned them, but those words…

Sans loved something about them.

“i’d completely forgotten about the entire reason we’re here,” he admitted. “i just want you.”

Feelings that were too complex for their poor, molten soul flooded them and they trembled against him, moaning as the feelings tried to come out. He wanted them, he cared about them, he wasn’t just here for the reset thing. Well, that was a main reason for his original motivation, but right now he was here because he wanted to be, and no other reason. Because he wanted to be with them.

He sighed and hugged them tight to his chest.

“hey, frisk,” he said, pulling back a little.

The amused, dark lust of his voice was absent, and he sounded… tentative? Nervous? They blinked and looked at him, curiosity pushing back the flames.

For all that they wanted him - and fucking hell, they wanted him - this was more important.

“i, uh…” he said uneasily and their focus sharpened yet further. He was confessing something? “what you said, it reminded me of a thing. who’d’ve guessed, i got distracted again.”

What could possibly have distracted him. It was a mystery for the ages.

“I couldn’t imagine why,” they said with an amused smile, then prompted him. “A thing?”

“uh, i should probably… i mean… i should maybe say stuff, tell you things, like, uh,” he said, adorably awkward. “the reason i’m still wearing stuff is because, uh, i feel kinda… uh… i dunno. exposed or something if i don’t.”

Ah, yes. He needed to emotionally connect, and so he was confessing his vulnerability. They wanted to kiss him, but that wasn’t an option. But their fire was very friendly with feelings of love, and stepped into the other room for these feelings that filled them now. They hadn't forgotten, certainly not, but their lust was simply a background need that somehow sharpened their focus, purging away irrelevant parts of their other feelings. It was oddly… easy.

“Vulnerable?” they said, supplying the word with a small smile.

“uh, yeah, probably,” he said.

He was so cute, this was amazing. They touched his cheekbone softly, affectionately. It was the equivalent of a kiss, right?

“I don’t want you to be uncomfortable, Sans,” they said warmly.

“kinda need to be vulnerable with you, though, right?” he asked awkwardly.

He didn’t need lips to be kissed on the cheek. Surely that was more the equivalent of a kiss, and surely that was allowed by now. Right?

They leaned in slowly and kissed his cheekbone with all the love they could pour into the gesture. They pulled back a little and smiled at him.

“It’s your core you’re most uncomfortable with, right?” they asked, and he nodded. “Maybe just taking off your shorts?”

“you just want easy access to my dick,” he accused, sounding amused.

The fire knocked politely at their clit and they grinned.

“This is true,” they admitted. “But also, I want you to feel good.”

He was silent for a long moment, looking away.

“i haven’t, uh, been with anyone since the incident,” he said, sounding subdued. “didn’t expect to feel this awkward.”

If they could kiss his cheek, they could kiss elsewhere, too. They moved down and kissed at his neck, amused at kissing invisible magic, but still trying to pour love and acceptance through the gesture.

“What would feel best for you?” they asked, continuing to kiss down his neck, to his collarbone.

“uh,” he said, sounding completely lost.

They giggled into his collar, kissing at him again. It was adorable.

“You’re really cute when you’re awkward and not being all dommy,” they said, gazing at him lovingly.

And they saw the most amazing thing. His cheekbones started glowing blue like the hell, that was so cute.

“i have no idea what you’re talking about,” he said with a huff.

“And you blush blue, oh my god,” they said, grinning and giggling.

“i have options. i can do things to you,” he said gruffly.

Hnng, they were very easy to distract right now, but they would try, this was soft and sweet and more important than the fire, no, it really was.

They bit their lip and tried to focus.

“This is true,” they murmured. “Anything you want, Sans, always. No matter if it seems unfair. Really. Wear your clothes if it’s more comfortable, or doff them if you’d rather. I am yours, either way.”

He sighed and leaned back, pulling them to his chest. They were snuggling, yay. If only they could have enjoyed an orgasm first. This was a strange sort of torment, but they couldn’t actually complain.

“i… i know,” he said quietly. “this is hard for me, but the fact is, frisk, i trust you more than anyone else.”

That was funny and sweet, and they laughed happily. He must be distracted right now, still.

“That’s not true,” they corrected him teasingly. “There’s Papyrus!”

“no, frisk,” he said, resting his head against theirs and just breathing into their hair.

Wait. What?

“i haven’t told him things,” he said, his tone soft and serious. “i can’t. i haven’t told you everything, either, i guess. but… i mean, i still don’t wanna talk about a lot of that, especially right now, but… the idea of it, it’s less scary with you than him.”

Warmth of an entirely different sort flooded them at his words, not washing away the fire, but relegating it to completely unimportant signals from their body. They inhaled, almost a gasp, as the understanding filled them.

He… he really trusted them that much. More than Papyrus. Despite holding them at arm’s length, despite trying to deny their devotion, despite encouraging them to be something else, despite all that… in the end, they had truly earned this depth of trust.

They trembled, their heart aching, and they hugged him with desperate joy and love and feelings they couldn’t possibly have put into words if they tried. The warmth reached their eyes, which watered, and a moment later they sniffled a little.

“Oh Sans, I…” they whispered and trailed off. They needed to tell him, but what words could possibly… “I’m feeling so many things, I have no idea what to say, or…”

He laughed lightly.

“you don’t have to say anything,” he said, stroking his hand through their hair, the touch so gentle and loving. “i already know.”

They felt seen, they felt understood, they felt… overwhelmed by the joy of all these feelings.

“i want you,” he confessed.

Yes, yes, the fire was definitely still filling them. They trembled from that, but also, this didn’t sound like lust. Or, not just lust. They listened, with warmth in their heart.

“sexually, as a friend, as a companion, as a rock in my life, as a confidant…” he said and they were going to burst from sheer joy. “and as something that i can trust will be mine, that will obey me, that i can just have absolute faith in.”

They were falling, they were flying, they were fulfilled. On some level, he had truly accepted who they were, and absolutely everything was right in the world. Tears began to overflow.

“i don’t know what feels more wrong - you being like this, or me wanting it. but if i’m ignoring that problem and just being real… the fact is, i do want it.”

In the end, the only thing that had stopped them was Sans’ fear that this was wrong. He, himself, wanted them. In the ways they wanted to be loved… maybe they weren’t hearing him right, maybe they were misunderstanding, but it sounded like they had it. That he loved them.

They squeezed him and trembled, tears dripping onto his shoulder. He sighed and ran his hand down their back.

“heh, sorry,” he said, sounding awkward again. “i guess my timing is kinda awkward.”

They laughed, their soul singing with amusement, with pleasure, with mirth, with joy.

“Don’t be ridiculous,” they said, a smile on their face and love in their heart. “This is… the nicest thing you could have possibly done. It’s even better than the sex.”

“you sure about that?” he asked, his tone dropping a little.

He shifted and they felt his erection press directly into their clit and they were immediately back to being about to die, gasping at the sensation.

“Both are nice,” they managed.

But, no, they would not be distracted from this. Uh. Not completely, anyway. They turned to face him and kissed his cheek again, though with more of a blend of love and lust this time.

“Thank you, Sans,” they murmured.

“yeah, yeah,” he said awkwardly. “maybe let’s just do the thing where i make you scream instead of all this sappy crap.”

They laughed at that, and the laughter grew in them. Soft at first, and then possessing them, their joy and mirth too much to be contained and just pouring out of them. They shook from their laughter so much that they fell from his embrace, collapsing onto the bed. He watched them, an adorably goofy grin on his face.

“Oh my god, Sans, you drive me insane,” they said once they finally got their laughter under control, beaming at him.

“that isn’t saying much,” he commented dryly, grinning right back.

“True,” they said, softly, lovingly.

He accepted them in all of their insanity. They sat up and moved to him again, running a hand down his chest. They were going to stop on his stomach like before, but…

The fire tugged at their hand and they bit their lip, wondering. If they weren’t allowed, he could stop them. They could trust him, they didn’t have to be so afraid of doing the wrong thing. They let their hand rest on his erection, despite the lack of invitation to do so, and it throbbed at their touch.

Okay, they were distracted again.

“So, for your clothes,” they asked, gazing up at him. “Do you want me to take them off?”

“uh… sure,” he said, still sounding adorably awkward.

Despite the searing lava insisting on tearing off his clothes and immediately jumping on his dick, they stayed focused. The love was softer and less demanding, but more important. And he was afraid. Feeling vulnerable was hard. They would make him feel safe with them.

Softly and gently, they ran their hands down his chest. They moved slowly, to make sure he never felt too overwhelmed. With a soft caress, they began to lift his shirt. They bent down and kissed at the strange, soft, semi ethereal invisible flesh of his core, feeling resistance at their lips but also not quite the sensation of contact.

Licking at him was even more interesting, a funny tingling pressure on their tongue that almost pulled giggles from them, but they didn’t want him to feel like they were laughing at him. The taste was of magic and death again, but more… burning, somehow. Like spiciness, not like pain.

They rose slowly, pulling his shirt up as they went, and once they reached his shoulders, he obligingly lifted his arms. They pulled off his shirt, stretching upwards, and then suddenly moaned when they felt his tongue on their breast, gently squeezing and then sharply striking their nipple.

He was horribly taking advantage of them, the bastard, and that was so hot and they wanted to beg him for more, but no, damn it, they were going to do this right. They trembled, but tried to glare at him. But there was too much love and amusement and affection on their face, there was no way the glare actually worked.

Harumph.

They would not be stopped. Maintaining their gentleness and speed, they turned to his shorts. He rose to his knees a little so they had space to work with as they slid his shorts down. His cock sprung up the moment it was freed and their breath caught.

Okay, this was impossible to ignore. They couldn’t help but stare, captivated, desperate, hungry.

“hey, look. its a BONE-r,” he said with a grin.

They couldn't help but giggle and groan at the terrible, terrible pun, and grinned up at him. Making the bad joke seemed to have made him more comfortable, and they couldn't help but beam at him.

But not for long. Something was demanding their attention irresistibly.

His cock glowed a faint, ethereal blue, seeming to throb softly. It looked oddly humanlike - though, they supposed, if he was a human skeleton, that made sense, actually. Mushroom head, gentle curve, though none of the texturing - it was all just the faint blue glow. It looked a little smaller than when he'd taken their mouth, but then, they knew damned well that he grew larger when he was falling more to his lust.

They wondered how large he could get and their mind stuttered.

It was interesting, too, how the glow faded towards the base, the very bottom of the shaft completely invisible. It was like a floating, erect cock made out of light was just hovering in front of a skeleton and that was so weird and cool.

They wanted so badly to… to do everything. To kiss it, to lick it, to explore with their hands, to suck it again, to feel it throb in their mouth as he came again, to feel it inside of them…

They couldn’t breathe, they were going to go insane. No, no, they could focus. He might let them, and then things would end faster, and that just wasn’t acceptable.

It throbbed and thickened, growing brighter. The way it did when he was overwhelmed before. He saw them staring hungrily at his cock and it was turning him on more and… okay, okay, damn it, they could do this.

But… but maybe…

Their will was cracking as they leaned forward and kissed his cock, trying to stay gentle, to stay restrained, to not throw themself at it in desperation, in worship, in need. Just a kiss, feeling the tingling pressure on their lips, lightly touching their tongue to him and tasting everything, and then pulling away, not taking him into their mouth.

Fucking hell this was hard.

Heh. So was he.

They finally succeeded, getting his shorts the rest of the way off, and tossing them aside. He looked so oddly nervous and uncertain, a bare skeleton with a pale blue glow at his cheeks and a throbbing glow at his pelvis. He was adorable.

“we got distracted by something different this time, but you know the plan,” he said, grinning at them.

Right. The cruel, awful, tormenting plan of doom that was going to make them erupt and die as the first human to ever die of pure, overwhelming lust.

Their face flushed and they squirmed eagerly.

“also, uh, it occurs to me - you aren’t cold, are you? i do have blankets,” he said.

Uh huh. He was definitely suddenly aware of the possibility of them being a little chilly now, and it had absolutely nothing to do with him feeling exposed.

“Sure, blankets are nice,” they said, unable to resist smirking at him.

The blankets were just in a pile at the foot of the bed, so they reached over and pulled one up, wrapping it around their shoulders. It was hugely oversized. They weren’t sure if they should offer it to him, too, or…?

He laid down on the bed on his back and gestured to himself.

“c’mere,” he said.

They moved on top of him, his cock right beneath them. Would he just take them now? He’d said he might.

They quivered in uncertain anticipation. Would there be torment, or pleasure? Or both?

“on my face,” he said and they flushed.

They swallowed as they moved upwards. In this position, he was covered with the blanket, too. They knelt, knees beside his head, their pussy inches from his mouth.

This was going to be awful and they wanted it so badly.

“you need to stay here and stay in position,” he said, his voice fully back to the thick amusement and desire it had before. “you can writhe some, of course, but you can’t escape me. you have to submit to whatever i’m doing to you, unless i’m about to make you cum, in which case you must stop me. and, of course, you must keep me informed about the effectiveness of everything i try.”

This was going to be so bad, they were going to explode. But fucking hell, his words stoked the fires even higher. How long before their will crumbled? They had to try, they had to…

They managed to express their understanding, though it sounded more like a squeak than words. They held themself in position over him, making sure they could hold this pose for a while.

“and don’t forget,” he said, almost as an afterthought, “none of that is a real order that you have to obey - it’s what i want you to do. as soon as you can’t handle giving me what i want, as soon as you’re starting to crack, and you beg for your own sake…”

His tongue pressed up against their entrance and they let out a desperate gasp. As soon as they cracked and were greedy, they’d have him, but… but he wanted to torment them, and…

And then it began.

His tongue was a marvel, an instrument of pleasure and torture they couldn’t have imagined. It moved deftly, with strength and ease, gliding over their pussy, their clit, the rim around their entrance, with agonizing precision. It shifted as it moved - sometimes a smooth caress, sometimes throbbing, sometimes fucking vibrating like that was fair, the hell. The texture changed, too, again and again - squishy, soft, steel cord, ribbed, studded, what might have been maybe mini bone blades that only touched their soul and not flesh, it was just ridiculous.

They tried to speak, they did, but fuck, it wasn’t fair, he was watching them smugly, and he knew damn well when they were about to cum, he kept bringing them to the edge, the bastard, it felt so fucking good.

But he never went inside them, he kept almost doing so, getting so close, teasing around the entrance, but never… they were a hollow void, aching, they needed something within, they wanted it so badly they could cry, but they could still resist, they still weren’t quite broken, even if they wanted to sob and beg relief.

Their pussy was nothing but fire and pleasure and their mind was almost lost when he decided to torment them in an entirely new way. His hand had occasionally caressed their ass while he worked his dark art, but suddenly they felt his finger caress their asshole and they flushed, shrieking in surprise. And maybe moaning a little, too, not that they’d ever admit it.

It was so wrong, but so fucking hot. His tongue disappeared and their legs clenched, but they held their position steady. His finger was still lightly stroking their asshole as he spoke.

“tell me how that feels,” he growled, his voice a dark command, and then his tongue punished them again with delicious pleasure.

“I’ve… I’ve never… ah…” they moaned.

How the hell were they supposed to speak when he was doing this to them? They couldn’t breathe, but they had to speak, they’d gotten an order, they couldn’t just not do it.

They almost managed to speak again, getting the first syllable out when suddenly his finger went a little into their ass… and fuck them, they almost came from that. And he knew it, too, the bastard, his tongue pulling away from their twitching clit like the absolute monster he was.

“Oh my god, Sans, I can’t…”

They couldn’t breathe, they couldn’t think, there was only fire and need and pleasure and his awful tongue and finger and they were so fucking good…

They couldn’t escape, they couldn’t pull away, they were trapped on the edge, doomed to writhe and whimper with need, squirming on his face.

He chuckled, laughing at their suffering.

But no, damn it, they would not be defeated. They would answer his goddamned question.

“It’s good,” they managed with a moan. “Fuck, Sans, it’s good, I’ve never… it’s so wrong, but it’s still good, I don’t want you to make me cum like that, it’s so wrong.”

They couldn’t cum from that, it would be the worst, and then his finger thickened and shoved all the way in and they almost… no, no, no…

“But fuck, no, please, that wasn’t an invitation to, ah…”

They were so embarrassed, this was so dirty and wrong, but they were going to die, they couldn’t...

“do you want me to stop?” he asked, a knowing laugh in his voice, his tongue disappearing with his words, now with only his evil, wriggling finger keeping them at the edge.

“No,” they said, confessing the awful truth. “Please… Sans… I can’t… I can’t take much more of this… god…”

His tongue returned and squirmed right at the entrance to their aching, desperately empty pussy.

Please, please, please…

It slipped in slightly, sending sparks through their veins, but only just pressing within, not the fullness that they wanted, that they needed…

A sound tore from their lungs, almost a scream, a cry, a desperate plea, they didn’t even know. Their body trembled.

“Yes, god, Sans, please… I… god… I need…” they said.

His tongue disappeared again and they could just cry, whimpering, but his finger continued to torment them.

“you need something?” he asked, amusement thick in his tone. “maybe this?”

As soon as he finished speaking, they felt something new. They looked down, and his tongue was… it was ridiculous, is what it was. Long and thick, not even vaguely pretending to be tongue-like, it pressed against their body as it kept extending from his mouth, moving upwards all the way to their breasts and licking at their nipple.

He could have done that inside them if he weren’t such a goddamned monster.

Part of their mind noticed that this thought made absolutely no sense and they told it to shut up.

The rest of them had other things to say, apparently, they didn’t even know what was coming out of their mouth as their fingers dug painfully into their thighs.

“Oh my god, yes, Sans, please, I need… I need you inside of me… I need to cum…” they whimpered.

He hummed, a sound of cruel satisfaction and his tongue briefly disappeared before pressing against their pussy, right against the entrance. It was so thick, now, almost as thick as his cock would be, was he going to… it would feel so satisfying, oh please…

They could feel the clenching as their body tried to somehow pull him inside, they needed him so badly…

They felt him begin to slide inside and they quivered with delicious anticipation. Would they finally have some true satisfaction, some true relief from the torment, was it finally…?

But as soon as his tongue passed within… somehow, it wasn’t there. They felt it go in, actively sliding into their body, but it was… what, disappearing once inside? Yet, their mind couldn’t stop the anticipation of the fullness from feeling him slide in, brains weren’t meant for this sort of mind-fuckery, they couldn’t… they couldn’t…

A scream tore from them, a sound of sheer madness and driving need, and they choked, their body convulsing, this was too much…

They couldn’t take this. Their knees trembled and they partly failed to do as they'd been told, moving from their position, if only a little. They fell forward, their hands by Sans’ head, gazing at him in desperate insanity, with only need remaining.

They didn’t know if he was ready for this to stop, but they… they just couldn’t…

“Please… god, please, Sans, I can’t… I can’t take anymore… I need… I can’t take it, I need you inside of me, please, no more, I need you…” they stammered out, and desperately hoped he could see it on their face, they couldn’t, they really couldn’t handle any more.

He looked smug as hell as he gazed at them. And then, with a familiar shifting noise, he was further up the bed. Before they could fully comprehend what happened, his hands were on their waist and his cock was pressed right up against their entrance. They trembled.

“oh?” he asked. “you want this?”

“Yes, please, Sans, please fuck me, please…” they whimpered, hoping that this was the end.

He moved slightly, pressing the tip inside them just the faintest bit, and then held still. The tingling hum of magic tormented them, they wanted to feel it all… They writhed, they squirmed, they couldn’t breathe, was he really going to torment them more?

But he was simply holding still, like he was waiting for something, and still with that smug grin on his face. They gazed at him, begging him with their eyes, please, please, please…

“aren’t you forgetting something?” he asked, his grin widening even more.

They stared. Memory. They needed to remember something.

Oh. Right. Their eyes widened at the memory of what they were going to have, and they looked over at the save point, then back at Sans. Were they really… was it really over, would they finally…?

He laughed, the sound rich with mirth and lust.

“i’m going to fuck you as soon as you’ve saved,” he said.

As soon as… they probably almost pulled something as they desperately lunged for the save point. But it was right beside them, that wasn’t really necessary, but still. They shoved their hand into the glow, trying to remember how determination worked for a moment, and then as soon as the wave of vitality from time poured into them…

Pleasure scorched them, flooding them, tearing through them as Sans thrust fully inside. No teasing, no taunting, just complete and utter satisfaction for their tormented body.

From the first thrust, they fell and fell, screaming as they were thrown beyond the edge, cumming so hard they almost blacked out, and he thrust again and they were nothing but a thing of pleasure, convulsing on his cock as he kept thrusting, as he gave them everything, everything…
