Frisk came on Sans’ cock for a delicious eternity that ended far too soon. And he was already driving them to another as he continued to fill them, to take his pleasure from them. He felt so good within them, thick and hard and tingling with magic. It was more intense than they could have imagined. And they’d given their imagination their best shot.
The half fallen blankets cushioned their legs, so that his bonier parts weren’t uncomfortable at all. His breaths were getting harder and he was getting a sheen of sweat, which they hadn’t seen since their fight on that day. Still weird that he sweated, but they’d honestly forgotten that detail.
He gripped them tightly, digging rough fingers into their skin as he pounded them. But no, that wasn’t fair. They started taking over the movements, riding his cock now that they were sane enough to move at all. He groaned in pleasure as they did so, and they silently thanked Undyne for her grueling workout routine. This was easy and the effort didn’t distract them from their pleasure at all.
A timeless moment of groaning bliss later, he grinned at them. He shoved their hips into the air a small ways, pulling them off his cock…
And then, with a faint shifting sound, he was behind them, shoving them forwards onto their hands. Without any warning, he filled them from behind, slapping their ass as he did so. He laughed at their shocked noises and began to take them in earnest. Once they started to get used to it, he shoved a finger into their ass and laughed again as they squeaked.
The delicious, wretched depravity of it all sent them over the edge for a second time and they screamed again, cumming on his cock and finger both. His cock swelled within them, twitching, and his fingers dug into their hips.
“fuck,” he grunted, holding them close and not letting them move for a moment, his cock pulsing inside them. “i forgot i need to… damn it, frisk, this is distracting…”
“It’s so good,” they said, flopped onto the bed.
“you feel amazing,” he groaned and took a sharp breath. “i almost forgot and was getting close… i need to do the thing. you need to be careful, alright?”
“I will,” they murmured, and then more words fell from their lips in a whisper. “Please, Sans, stay with me…”
“i’ll try,” he said. “i know it’s a bit repetitive, but the first position honestly will probably work best for this. i’d kinda forgotten why i’d chosen it.”
They giggled and pulled themself upright. With another flicker of magic, he appeared below them and immediately thrust inside with a groan of satisfaction. They began to move on him once more, riding him and letting him work his more literal magic.
He gripped them tighter and they felt magic pour from his cock directly into them. Wow, that was unexpected for some reason, and also really hot. It felt… strange. There was the burning pain of a soul attack, like they were accustomed to. But there was more. There was a flicker of feeling, like there were alien emotions just beyond a glass wall. Alien in the sense that they weren’t Frisk’s, but some felt familiar.
Guilt - even muffled as it was, Frisk was well acquainted with guilt. It felt a lot different than their own, though, even if it was still guilt at its core. Fear, uncertainty, self-loathing - these feelings were familiar, too, if only just barely able to be made out. Good emotions, also - it wasn’t all bad, but they couldn’t make those out as clearly. The kinds of good feelings that Frisk intimately knew clearly weren’t the same type as these.
These were Sans’ feelings, weren’t they? Not what he was feeling right this moment, but in general. They were feeling who he truly was inside. A surge of tender care flooded them as they gazed down at him.
They had paused in their movements, which Sans apparently decided to fix. He began to thrust into them again and they were torn away, lost in their distraction.
This pleasure was more tender, now, more desperate in a far different way. Sans clung to them, rather than merely gripping them; he filled them, rather than merely taking them. They leaned in close, their bodies pressed together, feeling his magic flooding them in so many ways - through his cock, through the contact with his semi-ephemeral core, through the strange connection that flooded them with pleasure and burning alike.
The burning wasn't bad at all, but it could kill them in time. Still, it was the same stuff as his core, really - with a bit of time and focus, they found a way to hold their will so that the burning was negligible and the connection was undiminished.
They needed to grab a quick piece of pie, since they'd rather not risk anything with his orgasm, just in case. Eating the pie like this was always such a shame - by bringing it to their mouth and willing to consume it, it faded into magic and healed them without them actually being able to taste it properly. An important skill to develop when trying to heal during combat, if less useful lately. Still, they were safe, now.
They kissed at his neck and fell to this pleasure, feeling it building up and up and up again. He, too, was building up, his cock itself growing thicker with his need. It wasn’t long before they came once more, writhing and convulsing on the feeling of him within, and their orgasm set off his. He groaned and gripped them so tightly they’d have bruises - not that they minded. His pleasure filled them in a strange way, not passing through their flesh, and remaining well contained and perfectly safe, while his cock twitched deliciously within.
They both panted out their fatigue, collapsed together in a happy puddle.
“That was amazing, Sans,” they murmured. “Thank you.”
“it was sans-sational,” he said and that set Frisk into a fit of giggles.
“That was so bad,” they said, unable to stop giggling.
“your pussy quivers when you laugh,” he said with a grin. “it feels good.”
They grinned back, but other feelings were creeping in and their heart wasn't in it. He thought this should probably never happen again. And if it didn’t work…
And… and they didn’t really want to reset. This had been so wonderful, they wanted him to remember.
“Did it work?” they asked.
“i’ve never done this before with a human,” he said. “it was different. i made the bridge, but i dunno. it’s the best i can do. i guess it’s time to see if it worked.”
“I don’t want you to forget,” they murmured into his neck.
“me neither,” he said. “for, uh, multiple reasons.”
“I’m going to try,” they said.
He took a breath and nodded.
They closed their eyes and, as they pushed on the feeling of time, they whispered, “Please stay with me.”
A hint of a black void, and then…
----------------------------------------
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…
It was a delicious minute later that they regained sanity enough to remember exactly when this loop began. Oh that was distracting.
“Sans,” they said as they started to ride him, hearing him groan in pleasure as he relaxed and enjoyed their efforts. “Do you remember…?”
He didn’t look surprised.
“i knew it wasn’t the first loop,” he said breathlessly as they continued to move on his cock. “it felt stronger than other impressions, but also maybe because it’s…”
He trailed off.
“We can try again,” they said. “Make the connection, Sans, and let me give you pleasure.”
He lay back and let them ride him. He was clearly disheartened by the failure, but still enjoyed the sex, so they tried to make it as good as they could. They didn’t really know what they were doing, but at the very least, they could learn to ride him better.
He forged the connection again, but it was vastly weaker. Frisk’s heart clenched in sympathy. This Sans had given up, hadn’t he? Oddly, they made something out in the connection they hadn’t really felt before. Maybe like taking a step back, to see the forest and not just the trees. Just a faint sense of loss - that was what Sans’ soul looked like, when one blurred out all the details.

Frisk’s heart hurt to feel it. They tried to give him what pleasure they could, and when he groaned with release, they didn’t make him face the end. As soon as he began to go limp, they pushed at time and reset.
----------------------------------------
And were immediately blown away by an overwhelming orgasm again. That was distracting in the best way.
Despite everything, it was hard to remain dour after an orgasm that intense. Maybe this wasn’t working, but they could take their pleasure of him again and again, and learn to ride him so well that maybe they could distract him from his own thoughts! Mmm, that sounded fun.
By the time they’d reached loop number ten, they had really gotten the hang of knowing when he was about to cum.
By the time they’d reached loop… number thirty, maybe, they’d gotten good at controlling when, exactly, he came.
By the time their loop count was in the fifties or so, they could thoroughly distract him so much that sometimes he couldn’t make the connection at all. Or, they could push him into making it about as strong as the first loop, but that took some major distraction and edging on their part. This was excellent fun to practice.
By the time the loop count was probably in the vicinity of the seventies, they’d grown thoroughly addicted to cumming on his cock and never wanted to stop. They never grew fatigued or hungry, never had their body wear out, never lost their sensitivity. And it was always the first time for Sans, always overwhelmingly intense, always - at least, now - mind-blowingly good for him. They’d never get tired of the sounds he made when they moved exactly right.
It was so good. But one thought kept poking at them. A type of intensity that they wanted to experience. They shouldn’t, they really shouldn’t, it was so wrong… but as they grew accustomed to the loop, as they started to take the lack of consequences for granted, they cracked.
“Sans,” they moaned, still feeling a thrill that it was him inside of them. “This is so good, but I want… I want…”
“i know,” he said. “it didn’t work.”
Oh yeah, that. And… it totally worked with what they were thinking. Why, they could pretend to be something other than a complete pervert! They gazed down at him, moving with exquisite precision on his cock, making him groan again.
“Let’s do more,” they said. “Let’s combine ideas. Kill me, Sans.”
“what the… damn it, frisk, no, that’s…” he spluttered.
Mmm, no, he didn’t get a chance to think. They rode him the way that would drive him to a height of pleasure, but not letting him cum, trying to distract him. He groaned with pleasure.
“It’ll be so good,” they said, closing their eyes again as they focused on blinding his thoughts with all of their skill. “It’s so good when you kill me, Sans.”
“i can’t kill you during sex, frisk, that’s way too far,” he said, a harsh note in his tone.
God, even just him saying that…
“But it’s good,” they said with another moan. They shouldn’t push, but it was hot, and it wasn’t like he’d stay upset at them because he wouldn’t remember, and it was horrible they were thinking that, but… “I deserve it, Sans, I killed Papyrus. You should kill me. I want you to kill me when I cum… it’s so good…”
It didn’t even make sense. If they deserved something for being bad, they should suffer, but this was pleasurable. It was like they were saying they should be rewarded for killing Papyrus, and it was awful, they were glad he wouldn’t remember this part. They didn’t word correctly when riding his cock, but then, they didn’t think they could be completely blamed for that.
“fuck you,” he said, a different sort of heat in his voice, with a sound like he was growling. “i’ll kill you when i cum.”
They clenched at his words. Holy fuck, that was the new record for hottest thing anyone had said in the history of ever, they couldn’t… another orgasm ripped through them and they cried out with pleasure… and with pain.
He swelled within them, his cock growing ridiculously huge, it felt like it was at the edge of tearing them open. It hurt, but it was so good, and they were continuing to cum around him, squeezing him, but they couldn’t move, he was too big to ride.
They weren’t paying attention properly, and suddenly felt skeletal fingers clenching their throat hard enough for even them to notice the pain of it. They were wrenched to the side, aided by a burst of magic as his eye flickered, an angry expression on his face. Hnng, too many feelings, that was hot, but also bad, they didn’t want him mad, but that’s kind of how he looked when he told them they should be burning in hell, on the first day they truly existed and that was so… that was…
They found themself on their back, Sans aggressively thrusting between their legs, tearing them apart and not managing to fully fit within despite his efforts. It hurt, in a different way, they’d never been hurt like this, and it was also so good, and they were just going to die, and they were also actually going to die, and that was so hot and…
“let me all the way in,” he growled. “let me take your fucking soul.”
Was this another candidate for “hottest thing ever said in the history of ever?” They couldn’t think. That was a problem for future Frisk to deal with. All current Frisk could do was hurt, and be pleasured, and give pleasure, and obey Sans in all things, always.
They would give him everything, and it would be so good. It was hard to focus, but they had to, they couldn’t fail, not at this. It was hard not to give too much, they wanted him to still be crushed by their too-small pussy. They needed to let him just have the depth, as far as he needed.
By a miracle of extreme practice at following through, they managed the focus required. His next thrust filled them and filled them and it was so good, they were going to die…
Er, but literally, actually, whoops. It was intense and pleasureful beyond imagination, but they didn’t want it to end just yet. They twisted, trying to keep some measure of focus, and grabbed a piece of pie, consuming its magic almost mindlessly. The power rushed through them, but some was lost somehow.
Not their concern. It was enough.
They fell back and soaked in the sensation. Sans was amazing in so many ways, and one of which was that he apparently had enough presence of mind to make the connection again. It was clearer than it had ever been, which was a shame, because Frisk was too distracted to actually make any sense of it. A profound, yet distant sense of loss, of old pain, of a deeply rooted isolation. That’s all they could really gather.
It also tore through their life more harshly than before. He'd been trying to control it before, hadn't he?
Sadly, between the burning magic of the connection, and the absolutely amazing, but also draining, sensation of his cock tearing through them, they felt their vitality dropping fast. They reached over and grabbed a second piece of pie, trying to focus enough to slow down the damage.
He began to cling to them more tightly, and they clung back. They didn’t want him to feel alone.
For a time, they just savored the experience, the wildly intense sensation of death, magic, lust, and pleasure driving into their very soul, of feeling Sans’ deepest self, of feeling a wildly oversized cock ripping into them, of feeling Sans holding them close and filling them. The feeling of dreams fulfilled that they never even dared to imagine.
They never wanted this to end.
… and to that end, they needed a third slice of pie.
Another timeless moment of connection flowed through them, as Frisk’s soul was drained into Sans, and Sans’ soul thrust into theirs, poured into theirs, burning them as it consumed them. Pleasure beyond anything Frisk had conceived of flooded them, a mixture of pleasures and pains that they hadn’t even known was possible, and wouldn’t have dared to hope for even if they knew.
And then Sans summoned the blasters.
Their pussy clenched tight at the sight, and they moaned as another shockwave of pleasure coursed through them. It was almost time. They would go from being the thing that Sans used for his pleasure, to being killed by him as he came, to be utterly immersed in his magic.
They couldn’t even think about how wrong it was, and only felt the pleasure at the prospect of experiencing the absolute.
He had been holding himself up, but fell forward onto them, clinging to them with a feeling of desperation - but it was different than before in ways they weren’t presently equipped to comprehend. It wasn’t the tender, near love-making sort of feeling of the first loop, but rather a thing of frenzied desperation and sheer need. But they’d grown to know him at his end - he was fighting to resist cumming. He was trying to stay in this moment.
They didn’t know what specifically had made him not give up this time, but it was so good to have him like this. Their vitality was draining fast, still, so they reached out for the second to last slice and consumed its magic, then fell into just savoring this experience.
It… it hurt in a strange sort of way. They didn’t want this to end, because this felt like their every dream fulfilled. Seeing Sans’ cracking will as the pleasure broke him down, knowing that this was about to be over, and that Sans would forget… it hurt. It hurt, because they wanted him, not just sharing this pleasure in the moment, but for him to stay with them, to remember, to have this pleasure shared for real.
And that pain opened the last floodgates within Frisk’s own soul. Nothing mattered, save loving Sans and giving him everything. Tears began to flow as they cried out his name. They tried to tell him things, about how much he meant to them, about how good this felt, but it wasn’t coherent. Mostly just words and sounds of pleasure and satisfaction poured from them.
It was so good, and they saw he was reaching his limit. Their pleasure mounted and there was no resisting this climax. They felt it take them, and also flow from them into Sans. With whatever scraps of will they had, they tried to strengthen that flow - it didn’t matter if it killed them, after all, as long as they survived long enough for him to cum. They wanted him to have everything - their pleasure, included.
It was too much for him and they felt him fall. His cock burned with magic as it poured into them without any restraint, and while they couldn’t think, they knew that even without his blaster, they didn’t have long to live from that alone. They let go. They let their life, their pleasure, their love, their everything pour into the connections. They let him take it all.
With only faint wisps of life remaining, they heard the roar of his blasters and felt their entire being burn. They smiled, though perhaps only in their heart. The cleansing perfection of their sins burning away, of everything being right and correct in the world, of the true peak of their existence…
The absolute had been achieved. Absolute perfection, pleasure, fulfillment, and completion.
And then this moment of sheerest perfection was interrupted by a healthy body and Sans lying beneath them, a desperate need driving them to move. They didn’t need to think to know what to do, and they fell onto him, feeling him inside and instantly cumming on his cock once again. This was just too much in the best possible way.
Maybe they’d never stop, and would just spend eternity cumming on Sans’ cock, sharing in these moments of absolute perfection with him, and never, ever having to give it up.
