I must say that the Dust part doesn't factor until wayyyy later. And there is a psuedo-Sin/Lime. Sooo. (Also, pretend that Dust is holding Error. Couldn't find any solo yandere Dust or yandere dust x error. -_-)

~Error's POV~

It's been a few weeks since Ink kidnapped me. He's kept to his promises, for the most part. He's fed me three meals a day, and he uses these meals as a way to bargain for more touch therapy. He hasn't harmed me, and has even let me off the chains, pun not intended, to go to the bathroom and wash up. However, he has to watch me shower or bath, so...I've tried to do it as little as possible.

Ink hums softly as he opens the door, holding a tray of underfell chocolate. I nearly salivate, but control my impulse.

"If you want to get this chocolate, you have to let me work off your pants, perhaps summon something I can play with, and last until I'm done playing, okay?" I look at Ink. He's determined, and when he's like this, the best I can do is please him, because saying no will make him mad. He won't hurt me, but he does scare me when he gets mad.

"Does that sound good, Error?~" I steel my resolve, before slowly nodding.

"5-50und5 f4nt45tic, Ink."

"Remember?~ I have a name I'd prefer you call me~"

"I-inky..." He sighs, smiling.

"Soon you'll call me master. But that's good enough for now." He sets the tray on a table and hums softly, walking over to me, getting on top of me, and grasping my pants, before thinking of a few things.

"Error, will you tell me a few things before we begin?"

1-1ik3?"

"What form will you be summoning?"

"U-uh..."

"It'll change how I play with you." I blush, looking away from Ink as I softly whisper my answer.

"F-f3m413." Ink smiles, nearly giddy as he summons something, keeping it hidden from me.

"Fantastic. Error. How would you like to sixty-nine?" I look at him, something like surprise or maybe shock running through my body.

"I just figure, I'm gonna be doing so much to make you feel good, the least you could do is make me feel good too. However, if it's too much for you, we can save that treat for another day." He studies my face, clearly patient. I think about it.

If I do this, I could focus on him as a way to distract from crashing, which would be good for me.

"5-5ur3...13t'5 5-5ixty-nin3." Ink almost can't contain his happy grin.

"We'll save that for last. There's something else I want to try with you first before we get there, okay?" I nod, and he begins to slowly remove my pants. My breath jolts, but he doesn't pay any attention to it.

Chocolate. Get through this, and you get yummy underfell chocolate.

Eventually he has my pants pulled down far enough, and gently taps my pelvis. I jolt from the tap, a female form summoning reflexively. Ink just sighs softly for a moment.

"So gorgeous, Error." I flush yellow, looking away from Ink. This was a mistake, because next thing I know, there is something slightly cold prodding at my folds.

"Error. I know you're a virgin, so I'll be very gentle with this thing. But I'm sure when I cut it on, you'll enjoy it." I look at him, tilting my head to see a small cyclindrical object in his left hand, and a small controller in his right hand. He smiles at me, and slowly inserts the object into me. I pull on the chains, the feeling both painful and not. It's not pleasurable, but it's not all bad either. It just feels foreign. Ink hums softly, pushing it in slowly, little bit by little bit. He chuckles as a whine or whimper leaves my throat.

"You know, I can tell you've never masturbated like this. You're so sensitive and tight~" Ink's eyelights shine pink, before going back to the soft white hearts they've been.

"Alright. It's all the way in you." He grins, and gets more comfortable, likely holding onto it perfectly.

"So, Error. Are you gonna beg for me to cut this on? Or are you just gonna try and wait my patience out?"

"I-inky...p-p13453." He grins, humming softly.

"Please what?"

"P-p13453 cut wh4t3v3r y0u in53rt3d in m3. P-p13453!" He smiles, sighing softly.

"You're too cute to say no to." He cut it on to the lowest setting, I presume, and immediately a vibration starts inside me, causing a moan to leave my mouth. I feel a crash about to come on, but focus on the chocolate.

"You are handling this really well~" With that, it's cut up to a higher setting. My body tries to curl in on itself from the pleasure, but I can't really do that. Ink giggles, humming softly.

"Maybe I should combine my two plans? See if I can make you cum?" I whimper.

"W-wh4t3v3r p-p134533 y-y0u m-m45t3r." He halts, looking at me, his hearts shining.

"Awe, Error. But First." He uses magic, probably to hold it where it won't slip further into me and where it won't slip out. He then waves the controller, cutting it up to max. I moan, trying to curl in on myself, before stretching myself as far as possible. He smiles, before removing his pants and summoning a female form as well, getting onto me in such a way his mouth is at my womanhood and his womanhood is in my face.

"Now, Error. I'm pretty sure you know what I want?~"

"Y-y35, m-m45t3r." Ink sighs contentedly, placing his mouth against my clit and begins sucking. I moan softly, but follow his lead, sucking on his clit. However, I can't hold in the moans from the vibrating thing, and so moan against his clit repeatedly. However, he seems to enjoy this, moaning against my clit. Eventually, however, he sits up, sitting completely on my face.

"Dear Error, might I recommend sticking those tongues of yours deep inside me?~" He tilts his head, and gets up, turning around and placing his womanhood against my face again, but now we can look at each other. He grins.

"There, now I can see how sexy you'll look, covered in my cum~." I take his suggestion, sticking my many tongues inside of Ink. The reaction is immediate as he throws his head back and moans. The vibrating thing causes me to moan as I continue to tongue-fuck the skeleton above me. Within seconds, I climax from the stimulation of the vibrating thing, impressed by how long I managed to last. However, I am now feeling too much pleasure, now just moaning against Ink's clit. He quickly climaxes on my face, grinning down at me.

"Won't you be a good boy and clean me up? I promise I'll do the same for you~" I moan, barely able to keep my eyes open. However, I do as he requests, slowly slurping on his cum as I continue moaning. When he is sufficiently clean, he lifts up from my face, heading back down to my womanhood.

"Mmm, sooo dirty~." He leaves the vibrating thing inside, using his magic to pull the chocolate over to me.

"However, you've been such a good boy, so here." He uses magic to feed me the chocolate, before sucking on my clit again. I moan, slurping up the chocolate. He hums sadly and thoughtfully.

"Error. How kinky will you go, before I cause a crash this time?~" I try to look at Ink, but can only see a chocolate bar float towards him. Then suddenly I feel him rub it against my womanhood, spreading the chocolate all over my clit and even slightly into my folds, touching the vibrator and pressing it slightly up and against my clit. I moan louder, jolting at the feeling. He grins at me, excitement in his eyes as he begins licking and sucking all over my womanhood. I'm still slurping up the chocolate in my mouth, as he works his way down and pushes the vibrator up against my clit while leaving it within me, somehow. I moan loudly, crashing.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~Still Error's POV~

I slowly blink awake, finding myself clean and my pants back on me. My memories are kinda fuzzy, but I can recall Ink removing my pants and getting me messy. A loud boom erupts upstairs, and sounds akin to it continue until it all suddenly stops. Then the door to the basement is kicked in. In walks my savior, Dust. He runs over, snapping the chains holding me and picking me up.

"Did that fucker do anything to you?"

"H-h3 did 4 1-10t 0f t0uch th3r4py...5-50m3 0f it w45..." I tighten my grip on Dust, nuzzling my face into his jacket. It smells of recent dust.

"Well, that fucker won't hurt you anymore." I slowly look around Ink's house, my eyelights shrinking when I see a small pile of dust, his scarf and brush laying nearby.

"I made sure of that." I cuddle my face into Dust's jacket, my mind going a million miles a second.

With these anti-magic cuffs, I can't fight Dust. How'd he find me? Why'd he kill Ink? Ink wasn't hurting me. What can I do?

Dust gets outside of Ink's house, before teleporting to a house in an AU, probably his house in DustTale. He leads me inside, setting me down gently. I take a couple steps, finding my waist hurts.

"You okay?"

"Y-y34h." I get up the stairs, smiling at Dust as I head to his room.

"T-th4nk5 f0r 54ving m3." He nods.

"You can have Paps room." I stop in place, smiling.

"B-but I'd r3411y f331 54f3r in 4 r00m with 4 10ck." Dust furrows his brow.

Did I fuck up?

"That makes sense. Take my room, I'll take Paps room." I smile, sighing softly in relief.

"R3411y, th4nk y0u, Du5t." He nods, and I make my way to his room, locking the door, and sitting against the door, tears welling up in my eyes as I look at the cuffs.

How will I get out of this?
