Sans always imagined what he'd say to his Dad, if he ever met him. If he'd scream. If he'd cry. The imaginary conversation came up a lot. Sometimes he'd practice in the bathroom, pacing back and forth as a little child, pretending the mirror was his Father as he'd rant to it. Just spew out everything. With the fact, under his breath, that he actually did wish for an explanation. No matter how evil his Dad was, Sans never met him. He knew it was nothing but a fantasy, yet he'd imagine a world where his Father wasn't evil.

But it was nothing besides a fairytale, huh?

His Dad pretended to be a teenage guy to get closer to Sans. If it was for simple bonding, or just to be included, maybe, just maybe, would Sans have understood it. But Mee - Gaster didn't stop at that. Of course he didn't. No, he had to go further. Flirt with Sans. Hold his hand, ask him out. Toby Fox, it was so much worse when he knew that was his Dad! Even remembering what happened, despite it being a day ago, made his face scrunch from disgust. His Dad. Sans had been attracted to his own Dad. He was going to hurl.

Wait, where was Sans? Why did he feel so weird?

Sans shuffled, feeling unfamiliar clothing press oddly against his body. It hugged him unnaturally, causing Sans to try and peel it away as his eye sockets pulled open. The clothes didn't budge.

Instead of being passed out on the forest floor besides Grillby, like he was before, he found himself in a bed. Not his old mattress, but a wide and expansive bed. As if Sans could start rolling, and his tiny size would never reach the end of the sheets. Purple curtains were draped across the bed, blocking out any other view of whatever room Sans was trapped inside of.

What in the actual f*ck was he wearing?

Sans never would have changed, that was for sure. Instead of wearing his favorite color or blue in his hoodie, with plain pants, he was dressed in something far more weirder. A purple dress that looked more like a gown than a male's outfit. His back ribcage was practically shown with how lowcut it was, and it pooled out across the floor. Trying to simply move was a hassle, there was no way he'd be able to run or build any speed with this many ruffles. It would have looked nice on him if Sans was trying to look like a girl, but he wasn't.

When he attempted to pull his arms back, he found them bound together by a bright, purple circle of magic around his wrists. What was the deal with purple?

Wait, didn't his Dad have purple -

Sans, trying to stand, stumbled back down as he found his shoes to be unstable. Once he managed to push aside at least five different layers of fabric from his stupid dress, he found high heels tightly strapped onto his feet. Yeah, no, he wasn't doing that.

The heels came off after a second try. He kicked them to the other side of the bed, scurrying over the edge and flopping to the floor like a bag of potatoes. Now free from his bed and curtain prison, he glanced up, looking around his room.

No, no, no!

He recognized the room. It as the same room they had saw on the tour of the castle, when they visited Sans' supposed inheritance. But it was in much more shape than when he last saw it. The vines were gone, and the old, dusty furniture was replaced with new polished items. A fireplace, previously cold and barren, now burst with a light bundle of purple flames.

No. Sans would not accept this. He wouldn't accept where he was, what he discovered, what was happening.

Run away. He had to run away.

Sans managed to push himself from the carpeted floor, forcing his magic to teleport him somewhere else, anywhere else. Instead, his feet sparkled, only for a moment, before the usual sparkles fizzled and his soul suddenly wretched forward in pain. He leaned against the wall, wheezing, and promptly vomited.

This wasn't right. He wasn't supposed to - Why was he here? Why didn't his magic work? Sans was happy, darn it, his life was good! Why did his Dad have to burst in and ruin everything?

Seeing that his magic was practically useless, Sans had to leave through a different strategy. He rushed to the balcony as fast as he could, pushing open the doors to try and escape. There had to be some sort of gutter pipe he could climb down, or something of the sort, right? Under the burst of wind, he looked around, trying to find any pipe to climb down.

There!

Sans saw one, and made his way towards it. He could -

What the f*ck was that?

Before the skeleton even had the chance to cross the distance, something flew up from under the balcony, snarling at him loudly. It was horrifying. Some type of attack, made entirely of bones. A full on dragon. A full on f*cking dragon. It stared down at Sans, before landing on the edge of the balcony, essentially guarding it. Sans tripped over the stupidly complex dress, sprawling out onto his back before he tried his best to practically worm his way back inside from the looming danger. Once behind the glass doors, he used his now bare feet to push it shut. No thanks.

Admittedly, he was now freaking out. Not only did Sans almost go on a romantic date with his own Father - that alone caused him to shudder - but now he was trapped inside of the castle by his Father. Great. Just great.

Sans went over everything that happened, what Grillby had told him. His Dad wanted to - to his own kid! What kind of sick, perverted man was he? To do something that twisted was just horrifying.

Sans had to get out. As soon as possible. He wasn't staying here with someone that batsh*t crazy. No way.

But how was he going to get out? That dragon thing was guarding the balcony, so that certainly was a no go. Should he try the... door that wasn't there, apparently.

There was no door.

Nothing. Noda. No door, no windows, nothing connecting to the hallway. The balcony was the only way out, all other doors remained nonexistent. How did... Sans remembered there being a door for sure during the tour, where was it?

He tried to find it, feeling up along the wall with his bound hands, but found no such luck. He was not staying here to fulfill any weird, perverted fantasies his Dad had. No. No way.

"Let me out!" Sans yelled, pounding against the wall. "You hear me old man? Let me -"

"Well, I'm not that old Sans."

A scream almost echoed from the boy. But he pushed it down, and turned.

When Sans looked, he found his Father. Not the fake human, the real skeleton. He was tall, and broad, with wide shoulders and a broken skull. Sans knew what he looked like, as much as he didn't want to think about the man that abandoned him.

"Hi... Dad," Sans hissed, tail curling against his back as he took a step away.

"Oh, don't be like that. Weren't you the one that complained that I abandoned you?" Gaster tilted his head to the side. "It wasn't even my fault, since I believe Grillby told you everything."

"Yeah, he did," Sans said. However, that jolted a spike of panic throughout him. "Wait, did you -"

"Kill him? Rape him? Feed him to the bears? He was unconscious, much like you were, so I could have done anything. Anything at all. Very tempting." Gaster pressed a hand against the side of his face, giving a snide grin. "I think I'll tell you after you do something for me."

"Do what?"

Sans felt fear over Grillby's wellbeing thump throughout his soul. Gaster didn't... he wouldn't... Please be okay, Grillby. Please.

"I want..." Gaster leaned forward, and despite his body now being tilted at a ninety degree angle, he was still taller than Sans. "A kiss."

Ew.

Sans revolted back, almost gagging at the mere thought of kissing his Father. He didn't even love him as family, he was an evil tyrant!

"Then you'll tell me where he is, right?" Sans would put the wellbeing of his friends over his anyday, anytime.

"Of course."

Gaster stood, patiently and confidently waiting, because he knew Sans would comply. And Sans did. For Grillby, for Grillby -

He forced his body forward and landed a small clank onto Gaster's face. The simple touch made Sans shiver with disgust. Gross. Gaster wasn't warm at all, his bones were cold, almost freezing. He didn't have that warm, gentle touch Grillby had. The kind that made Sans want to curl against Grillby more. This feeling made Sans want to huddle up and vomit again.

"You call that a kiss? I understand I'll be your first, but still -" Gaster harshly grabbed Sans' chin, forcing him forward, "- It was pathetic and stupid."

If it wasn't that gross the first time, it definitely was the second. Gaster forced Sans into another kiss, this time long and harsh. When Sans tried to pull away, Gaster kept him put, digging one of his fingers into the side of Sans' mouth and digging a summoned tongue into him. It didn't feel pleasant at all. It was gross, as if a slimy snake wormed its way into his skull and he couldn't get it out. His legs tried to kick out, and he wanted to scream. It was horrible. His first kiss, stolen by this vile, disgusting Father of his was accompanied by the taste of vomit still present in Sans' mouth.

The moment Gaster let go, Sans dropped to the floor, choking back the urge to puke as he pressed himself back against the wall. "No no no no - I was - my first..." Sans pressed a hand against his mouth, staring down at the floor.

"You were going to give it to me anyway, I don't see why you're freaking out. You liked Meer."

Sans was going to throw up again. He swore he was.

"Where is Grillby?" Sans demanded.

"Oh... I don't know," Gaster said, shrugging. "I left him there when I took you. It could be anyone's guess to if he's alive or not."

"You -" Sans curled a hand against the ruffles of his dress, shaking with anger. So Sans didn't even have to do that? "You bastard!"

"Ah ah ah." Gaster tsked as if Sans was a misbehaving puppy, shaking his finger back and forth. "I don't think you realize your situation. I wouldn't have simply kidnapped you here without a plan, I am known for those."

Which meant Gaster had another horrifying thing to reveal to Sans, didn't he?

Why couldn't things have stayed good? Sans was happy! He and Chara got along, he had friends, had a future, and it's all gone because his Dad was a psycho! Sans wasn't sure if he wanted to curl onto the floor or just break out sobbing. Maybe he should do both.

"So, first off, let's get some ground information out of the way. Yes, I was pretending to a human teenager to have sex with you. And yes, I do fully intend to conquer all realms to rule over everyone. But first, I do need a heir. Which means I need to breed one." Without even asking if he could touch Sans, he lightly ran a hand over his skull, as if he intended to pet Sans. Please don't. "Naturally it'd be the best idea for you to. Not only would we keep our bloodline pure, but it'd provide me with a cute little wife."

"I'm not your wife, I'm your kid!" Sans tried to slap is hand away, but Gaster grabbed the purple binding magic, easily stopping that attempt.

"Not yet you aren't. But you will be, soon. I get everything that I want, and I want a nice little wife who swoons over me and begs me for more in bed. One who'd let me do whatever I wanted to her cute little body and would thank me for it. Obviously, you're not there yet. The Cheshire Cat was only attractive at the time because of her age and cat features. If it wasn't for those ears I'd have no interest in her whatsoever. But I decided to have sex with her to produce my perfect bride. I would have simply kidnapped her and try again if you grew tall and uncutesy, but you've remained small and cute, so I don't need to."

Each word said made Sans only want to push him away more. He had to get away somehow. He had to run and run and never look back.

"That's where your desirable traits end. All I wanted was a cute little feline kitty cat to be my dotting wife while I conquered the world. And, well, if you don't participate..." Gaster trailed off, looking towards the window. "Your sister has a rather cute face. She'd be a fine replacement."

Was he seriously using Kitty as a threat?

"Don't you dare touch her!" Sans snapped, trying to lunge at Gaster. "She's my sister, don't you dare -"

"Calm down, as long as you participate I won't do anything to her. I wanted you first, she's simply my backup wife if anything happens to you. So keep that in mind, you're replaceable. Expendable. You are more preferable of you two because of your age and features, but if you become too much to handle, I can simply dust you and kidnap Kitty. So comply, my little wife."

He was using Kitty as a hostage. The threat was blatant. It was the victim situation, in a sense. Let someone else get hurt, or take the pain yourself. And Gaster knew Sans would volunteer himself over his sister. Sans always would, as would she for him.

"Fine."

Gaster hummed happily, as if his mood suddenly did a complete 180, and rubbed the side of Sans' cheek affectionately. Sans tried his best not to flinch away, trying to comply with this demon man before him. For his sisters safety.

"What was that dragon thing, outside?" Sans asked.

"Protection. So you don't try to escape. It'll let you be on the balcony, but if you try to leave, it'll stop you. That includes any attempts of suicide, it'll simply catch you and drag you back. Not to mention it'll be watching you whenever I'm away, to ensure you aren't doing anything I wouldn't like."

Sans couldn't even kill himself. Gaster was going to be watching him that closely, huh?

"And these clothes, did you change me while I was..." Please no please -

"Simple magic. I had things to do."

Whew. If Sans found out his Father undressed him while he was asleep, he would have burst out sobbing.

Still, none of this was good. Sans couldn't leave, couldn't even control if he lived or died. And if he didn't obey Gaster his sister would be next on the chopping block. Sans was stuck. There was nothing to do but listen to this sicko and try to figure out a plan.

"And what about everyone else. Are they -"

Gaster growled in annoyance, snapping a hand against Sans' mouth and clasping his jaw shut. "Pretty wives shouldn't ask many intellectual questions. It's not very attractive. F*cking shut it now."

Okay, he was sexist too. Just another reason for Sans to hate him. Glad to know years of utter hatred were not wasted.

Seeing that Sans wasn't up for an argument, Gaster smirked. "Good, you're a quick learner. That'll be put into use. If you continue to behave well without many screwups, I'll make sure out first time isn't painful for you."

Was he talking about... No. Ew. Ew.

"Relax, I'm not going to do it yet. It's always better when they're begging for more. You aren't quite ready yet, either."

Sans blinked back tears. He wanted to shove Gaster away, but he didn't want to risk Kitty's safety. His chest felt thick, as if he was being crushed by the weight of a thousand trucks.

"Please don't," Sans choked out.

"Oh Sans, it's too late for that. You're the one who didn't want to follow your destiny. So this is your fault, I'm simply holding you responsible."

He froze. "W-What?"

"You rejected the book. You rejected your destiny. If you hadn't done that, Mettaton wouldn't have released me. Your friends wouldn't be suffering right now if you hadn't. In fact, I would have been dead. If you had played along with the story. But you were selfish, and now all of your friends, your family, have to suffer. That's why you're here. To make up for your stupid decision by breeding a new Evil tyrant. Because that's all you're ever going to be useful for."

This time, Sans couldn't blink back the tears. Gaster watched, smile wide, as if he enjoyed watching Sans fall into despair, and perhaps he did. With a wave, he disappeared in a flash of purple, leaving Sans alone all over again.

On the floor, Sans stayed. Sans sat in the silence, hearing the grumble of a dragon outside, and begged for help. He let out a sob, high and desperate for something, anyone, to come and save him from this fate.

But nobody came.
