(Okay so at the time of writing this Errorink is the winner with smut. Chances are I'm gonna do the other two as well, but I needed to know which one to focus on most. Why am I not surprised that Errorink won?

Are y'all okay? Are y'all horny?

I do not condone anything that Error is doing in this smut. This was honestly the best I could come up with. I don't know how to write a yandere smut and make it healthy.

Also, additional note: How would y'all feel about some... Errorink404 smut? Error x Ink x Error404? Eh? Eh?)

"YoU'rE sUcH aN iDiOt, InK."

Error's voice was sharp and cold as he stormed down the hallway, dragging Ink along behind him. Ink was muttering something repeatedly under his breath, clawing at the floor. Desperate to grab ahold of something-- anything-- that would postpone what was going to happen to him. He'd been so close to escaping from this prison that Error put him in. He'd been so close, and yet his victory was so far away.

Error opened the door that led to the basement and stormed down the stairs, not bothering to pick Ink up. The smaller skeleton yelped as his chin started to thump against each of the steps. When they got to the bottom of the staircase, Error picked him up by the back of his shirt. The basement was the room where Error would put him if he misbehaved too much, so there were lots of things down here for his punishments. Ink yelped again as he was thrown to the ground, but Error paid his pain no mind.

Instead, the glitch went over to the chair in the room. It was directly beneath one of the bright, unshaded lights of the basement. This chair had been used for several purposes, primarily to keep his victims tied down while he tortured them. He sat down in the chair and pulled some strings from his eyes, shooting them out to wrap around Ink. He pulled his darling over to him, hoisting him up so he was laying across his lap.

Error ran a hand along Ink's back, wondering what he should do to him this time. He'd thought about spanking him, as that was the usual punishment he got. Enough to make his bones sore and in pain, bruised and sensitive to even the lightest of touches. He wanted it to really leave an impression on Ink this time, so he would think twice about trying to escape from him. He wanted him to feel pain like he'd made Error feel. Unfortunately for Ink, he came to the conclusion that spanking wouldn't be enough to satisfy his anguish.

It was a shame. Error really didn't want to hurt him, but if a spanking session along wouldn't be enough to make Ink remember his place, then so be it. This wasn't the first time he'd have to go a step further, but he hoped it would be the last. He truly didn't take any pleasure in hurting him. However, he had to make sure that Ink could grasp the concept of how pain he put him through every time he showed his resentment towards him or tried to escape. Even now, Ink was struggling to get away from him.

Error brought his hand down on Ink's rear. The slap echoed off of the walls and back into both of their ears(?). Ink's head snapped up and his back arched, so much fear shining in his heterochromia eyes. Error knew that it was wrong to put his hands on him like this, but he didn't care. Ink deserved this. It was all his fault that this happened, all of it.

Ink was the one who caught his eye. Ink was the one who was nice to him regardless of how much of an asshole he was being. Ink was the one who let things get to this point. Ink was the one who tried to run away from him, who caused him this pain. Ink was the one who caused all of this.

(Error, one of my favorite young bloods, go get some fucking therapy.)

"ShUt Up," Error hissed at him, delivering another smack. "ThIs Is YoUr PuNiShMeNt."

Ink whimpered as he gripped the edge of the chair, biting down on his lip. Error was being aggressive and harsh with him, more than enough to convey his point. The spots where he slapped Ink were stinging. Ink opened his mouth to beg him for mercy and his forgiveness, Error beat him to it. The glitch grabbed his cheek and pinched hard, fingertips digging in a bit, and he made Ink look at him. Ink gulped at the sight of such a cold, cruel, and empty expression.

"YoU tHiNk YoU cAn JuSt AsK fOr MeRcY, hM? ThAt YoU cAn GiVe Me SoMe HaLf-AsSeD aPoLoGy AnD eVeRyThInG wIlL jUsT bE fInE?" He questioned, dropping Ink's head back down. "I aM bEiNg MeRcIfUl RiGhT nOw. I cOuLd ToRtUrE yOu AnD bReAk EvErY pArT oF yOu If I wAnTeD tO. So Be QuIeT, yOu StUpId LiTtLe BrAt."

Once again, Error's hand made contact with Ink's body. Ink couldn't help the pained yelps that came from his throat with each hit. He bit harder on his lip and forced his head down, fearing that the sight of him crying would only push Error to go further. Apparently, his efforts to suppress his wails and tears meant nothing to Error, because he grabbed him by the neck and forced him to sit upright. The next thing he knew, he was sprawled out across the floor of the basement, cheek stinging in pain.

"YoU rEaLlY aRe A dUmB lItTlE sHiT, aReN't YoU? Is YoUr OnLy BrAiN cElL tHe SiZe Of A pEa?" Error sneered at him, glaring daggers. "I'm ThE oNe WhO iS iN cHaRgE hErE. I oWn YoU."

Ink whimpered again. He missed his life before Error dragged him into this hellhole. He missed running around with Dream and Blue, hoping from one AU to another. He missed the light yellow and comfort of his Doodle Sphere. He missed the regular fights between the Star Sanses and Nightmare's gang.

Another wretched sob left his throat as Error stood up from the chair, grabbed him by the back of his shirt and started to drag him along the ground. There was an old mattress in the basement for nights when Error would lock him down there. It didn't have any sheets or pillows, only a thin and tattered blanket. Error threw him onto the bed and Ink flinched when his back hit the wall.

He hoped it was over now, that Error had decided to pity him. He felt dizzy and the pain from the spanking was setting in quickly. Error grabbed onto his arm and turned him over, forcing his ass into the air. Ink hoped he was just... ugh, admiring... the work he did to make him ache like this.

"EcTo. SuMmOn It."

Ink's eyes snapped open at those words. He looked at Error with wide eyes, like he was silently pleading for him to reconsider. Whether he understood Ink's message or not, he didn't show any reaction to his effort. Instead, he only slapped Ink's already stinging rear again, making him cry out.

"I sAiD sUmMoN iT."

Hot tears rolled down Ink's face as he obeyed Error's command. He willed up some magic and conjured his ecto-body, although he tried to do it as slowly as he could without stirring up more of Error's wrath. Error grabbed his shoulders and forced him up onto his hands and knees, getting behind him on the mattress. He tensed up when he heard a sound of a cap opening. Ink's breath caught in his throat as Error started to push his fingers inside of him. His body froze and the tears started to fall faster, but Error evidently didn't care much about his comfort right now, if at all. 

"YoU sHoUlD rEaLlY tRy To ReLaX. Do YoU wAnT mE tO sHoVe My WhOlE fIsT iNtO yOu?" Error asked him with a snarl. "BeCaUsE I'lL dO iT... aNd YoU kNoW I wIlL, dOn'T yOu?"

Ink nodded with what little strength he could muster. His body was fighting against him, but he tried to force his hole to relax and stop clenching. One of Error's fingers shot inside of him, sending pain through his body. It was nowhere near the pain that would come if it had been his fist like he threatened, but it still hurt. His body wasn't ready for it, but Error didn't care. In his eyes, Ink deserved to be in pain right now.

He added in a second finger shortly after. He knew that he would most likely cause Ink's ecto-body to tear and bleed a bit, but he didn't really care at the moment. He wasn't going to kill Ink, he knew that much. He used his two fingers to spread Ink's hole open a bit, just enough for what he was planning to do. He grabbed the bottle of lubricant, which he'd applied to his fingers not too long ago, and squirted some of it directly into his hole. His eyes narrowed when Ink's hole started to clench again, looking at the shorter's face. Ink quickly averted his eyes.

"Oh StOp ThAt," Error scoffed. "If YoU wAnT sOmEtHiNg To CrY aBoUt, I'lL gIvE yOu SoMeThInG tO cRy AbOuT."

Ink nodded his head and murmured a 'mhm', but in his head he was giving a sassy remark to his words. It wasn't his fault his body reacted that way to pain. However, he had to keep that thought to himself. Otherwise Error would fulfill his promise on giving him something to cry about.

The sound of moving fabric made him look behind himself, but he wished he hadn't. Error had conjured up his own ecto-body, his cock visible. He hadn't even bothered to remove his clothes. Error didn't see a reason to remove his clothes. All he was going to do was fuck some sense into Ink. Remind him of where he belonged and who he belonged to. Remind him what pain and consequences were. And then he'd leave him down here for the night, in a possible pool of his own blood, cum, and liquified magic.

"R-Ru-u-r-u-u," Ink tried to say, his formed ecto-tongue feeling limp and thick in his mouth.

He wanted to say no to him and to beg him to stop. He would promise him, swear to him, that he would be good and wouldn't try to run away again. He would tell him that he would listen to whatever he said and do whatever he told him to. He would accept any other punishment than this. But Error didn't want to hear anything he had to say. Ink lurched forward, hiccuping and choking on his breath as Error's hand made contact with his bruised bottom.

"YoU rEaLlY dOn'T kNoW hOw To ShUt Up, Do YoU?" Error asked with a growl, pressing the tip of his cock against Ink's entrance. "SuCh A sTuPiD sQuId. ThAt'S wHy YoU sHoUlD jUsT dO aS yOu'Re ToLd."

He started to push into Ink's body, gripping his hips as he forced himself through. Ink's back arched and his head tilted back, sharp cry of pain slipping past his clenched jaw. It was obvious how much pain he was in, from his fingers digging into the mattress to the fact that his pupils were shaking. Error was just as obvious with how little he cared about the pain, if at all. He didn't wait for Ink to adjust or even let him adjust in the slightest, as he was already starting to move.

Ink's body snapped into a fight or flight response, desperately trying to get away from Error's assault. He wailed and sobbed and flew into a hysteria, hyperventilating as his body flared with pain. It was easy for Error to keep him in place, however. Those medicines he'd had Fell!Sci create to bring Ink's natural strength down and make him physically weaker were really paying off. If Ink knew what they were he would've never agreed to take them, so he'd had to mix them into whatever Ink ate or drank, including his vials.

"StAy StIlL, dOlL," Error grunted. "YoU bRoUgHt ThIs UpOn YoUrSeLf."

That did nothing to make Ink stay still or stop hyperventilating, and Error had only just started. He was groaning at how tightly Ink's walls were squeezing him. It was actually almost hurting him, like his body really was trying to force him out. Ridiculous. Ink was his darling and was meant to fulfill each and every one of his desires. Whether that be by satisfying him as a romantic partner, as a servant, or as a living cumsock.

(Error no. Therapy. Actually therapy won't save you in this story.)

At some point, the inner walls of Ink's ecto-body were starting to rip and tear. Liquified magic oozed out of the internal injuries and acted as another lube, slicking up the passage even more. But the rubbing of the magic against his torn walls only caused Ink more pain, but he had no choice other than to endure it. The mixture of liquified magic started to mix with the lubricant that Error had squirted into him earlier and the inky blood starting to seep out from his injuries prior to now. It dripped out of his hole each time Error thrusted, soaking into and staining into the already dirty mattress.

Error settled on a rhythm with his thrusts as he moved in and out of Ink's ecto-body. Ink's body had given up on trying to escape him, much to his satisfaction, but he hadn't stopped crying or hyperventilating. Any other time he would've taken pity on him and comforted him, but he was far too pissed to give a damn now. But now he could settle for one hand gripping Ink's hip, continuing to move his own hips quickly.

"Oh KiKi, FuCk..." He groaned. "YoU fEeL sO fUcKiNg GoOd..."

Ink lowered his head into the mattress out of shame, but this only raised his ass higher. Error grinned at this. Not just how Ink's ass got raised higher, but his clear shame and guilt from the situation. He bet Ink was silently lamenting all of his poor choices in that tiny mind of his. Not only that, but the way his body was reacting was making him feel good too. The way his body was moving in response to Error's invasion of it made him feel all tingly inside. Such an odd feeling.

Error thought back to whenever he and Ink had fucked prior to this moment. That was before Ink had discovered his true nature and his fascination-- no, obsession-- with him. There were several things they'd done then. He'd have a hand between Ink's legs while he fucked him, groping and toying with his clit or cock, whichever he had summoned. Other times he let Ink ride his cock and set his own pace, bouncing on him until he orgasmed on his own. Of course there was also the fingering, hitting his fingertips up against Ink's little spot to drive him crazy until he came.

But now wasn't the time for making sure that Ink felt good or even orgasmed. He'd made Error feel dreadful and just awful, so he was just returning the feelings. Ink had to suffer too. It was satisfying to see him struggling beneath him, both to stay awake and to take all that Error was giving him. Error had told him several times to keep his mouth shut, but now he actually preferred how he was sobbing out both his name and his nickname.

"I lOvE yOu," Error groaned out, not really caring if Ink understood him or not. "I lOvE yOu So MuCh, KiKi. ThAt'S wHy I'm DoInG tHiS, aLl Of ThIs-- BeCaUsE I lOvE yOu."

Ink didn't verbally respond with anything other than a garbled sob of his name, but he did nod his head in acknowledgement. That made Error's chest tighten as that warm feeling he always got around him skyrocketed. He started to speed up his thrusts, his cock occasionally twitching. Ink howled in agony as his walls were torn more. Error cooed as he allowed himself to pity Ink now, now that he learned his lesson.

He grabbed Ink's hips again, tighter than before, and started to pound into him. To him to felt like pure bliss, but to the captive beneath him it felt like pure hell. Error leaned down to press himself against Ink's back, flattening him against the mattress even more. He bucked his hips forward and went in deep, sighing in satisfaction as he came inside of him. When he pulled out, his cock was covered in the mixture oozing from Ink's hole.

"YoU'rE sTiLl StAyInG dOwN hErE fOr ToNiGhT," Error told him as he stood up, pulling his shorts back up. "I'lL cOmE gEt YoU iN tHe MoRnInG."

He pressed a kiss to Ink's cheek as he pulled the blanket over him. He turned on his heel and walked back up the staircase, the door closing heavily. This left Ink submerged in the pitch darkness of the basement, as Error had turned off the lights before closing the door. His ecto-body faltered and collapsed in on itself, letting the rest of the fluids stored within him spill onto the mattress. He clutched the blanket tightly, entire body shaking as his sobs echoed through the basement.

How had he ever come to love such a cold-hearted, sadistic bastard?

(*handing out holy water guns* You all may go and corner Error, you all may go and corner Error. In fact I encourage you to go and corner Error. Go and corner Error. Do it. You know you want to.

Maybe take this crowbar too--)
