Parental instincts.

That had always been an aspect of Sans' life. Sans was a parent, he always cared for children and loved raising them. That's why he didn't mind having so many, he loved all of them dearly. Always wanting to do the best for his children, wanting them to live the happy lives that they all deserved. That's what being a parent was about, working your hardest to make sure they could be happy.

Even with their special 'circumstances'. Children of serial killers would have a hard time living a comfortable life, but Sans managed to pull through. The underground had actually been the perfect place to raise them, running to the surface only to buy things that they would need. Underground, his children didn't need to be afraid or hide who they were. It was open and large, perfect to raise his family in.

But Sans did set up some rules about going to the surface. None of his children could ever go up there alone unless they got permission from Sans, and even then they could only go to certain towns that Sans had deemed 'safe'. Sans had to find the locations of all of his old friends and list those locations as 'never visit' for his children and his friends. Some of his children took on his skeleton gene, they could recognize them immediately. Towns with large police forces were also added to the no visit list, for obvious reasons. Other than that, as long as they had their phones on them, Sans sometimes let his children go out and see a movie. He didn't want to deny them from the surface, after all. They were kids, teenagers, they should experience their teenage lives. A few of them even made a couple of friends, which he was proud of. They just couldn't ever invite them over or tell them about their parents.

And Sans often took his children out with him. Going out for birthdays, or just tagging along for shopping trips were all things they did. Sans did start using more resources from the underground, like starting a garden and having Laughing Jack summon some stuff.

It had just been a normal, late night trip to the store with his son. One of his daughters had ate his snacks, again, so Sans decided to take him to the store to buy some stuff. Usually Sans would have just sent his children to go alone, but the last time he did, poor Hewey had ended up in a ditch.

And they had to buy a new wheelchair.

Pushing his sons wheelchair down through the store, Sans glancing at the shelves full of food. At first, Sans had been worried for his child. Seeing the baby be unable to even wiggle his legs, unable to crawl and run, Sans was scared. Scared that his son just... might not make it. Thankfully, a few lookovers from Eyeless Jack, and a lot of research gave more insight. He was paralyzed from the waist down at birth due to a spinal defect, he couldn't move anything below his waist. He wasn't going to die.

It wasn't as if that would stop Sans from loving him any more. Hewey was his own child, just because he had to use a wheelchair didn't mean that Sans would disown him. It just meant that Hewey's siblings like to roll him down large hills. Very, very long and large hills. As a result, Sans was mainly the one who pushed his wheelchair when Hewey didn't want to. Hewey could move his own wheels, but Sans didn't really want to send his son out alone in public when he couldn't defend himself.

Hewey was Tim's kid, a 15 year old with the personality of some old detective who has just seen everything he already could. That was the best description for Hewey. It probably didn't help that everyone made jokes about him being paralyzed, Hewey had just heard everything by that point and was just tired of everything. He got that from Tim, and he got his talking skills from Sans. He was witty and quick with his tongue, and did not accept any sh*t from anyone else. Even though he couldn't attack anyone, he would be able to retaliate quickly with simple words. And if that didn't work, he just threw something at them then ran over them with his wheelchair. It worked enough. There was nothing like waking up one morning at 3 AM to find Hewey running over his other child.

"How about some cookies?" Sans taunted, slowing near some shelves fully of chocolate chip cookies.

"I hate you," Hewey groaned, eyes trailing over the snacks.

"Love you too, sweetie," Sans had said, pointing at some more chocolate items on the shelves. "How about those? I know chocolate is your favorite."

"Dad, I will do the Kennedy assassination on you, I swear," Hewey snapped.

Sans grinned at him. Relocating themselves in the chip aisle, Hewey finally grabbed some chips to satisfy himself of his lack of snacks. It didn't take long before they were out of the store, Sans grabbing a few packets of gum on the way out. Their conversation had consisted of simple topics as they exited the store, continuing out onto the dark street.

Now, Sans wasn't sure exactly when it happened. One moment everything had been normal, the conversation continuing normally. But then the next moment, the air went cold. Something was just wrong, the air chilling.

He heard it before he saw it. The soft humming of a vehicle in the distance, the sound emerging from the darkness down the road. There was a sudden chill to the air, and his chest felt heavy. As if something didn't belong.

"Dad..." Hewey had said quietly, one of his hands reaching up behind him to grip onto his Fathers arm.

"I felt it too," Sans muttered.

It was a different feeling, one he had felt throughout his life. The feeling of being watched, the feeling of something not belonging. But it was much more intense, more there, he couldn't zone it out as he usually tended to. Before, he usually forgot about the feeling of being watched by something that didn't belong, it was so normal since he came to the surface. But now, it was concentrated, filling the air and making a weight in his chest.

Then came the source of the sound.

The headlights shot through the darkness, flickering and broken. The bus containing the lights was old and rusty, shuttering as it drove towards them.The outer red and orange paint was chipping, scratches and dents littering it as if it had just been attacked. The inside was almost pitch black, Sans couldn't see through any of the windows. When it started to approach them, gears started to grind together as it slowed, signaling that the breaks were having pressure applied to them.

"Should we...?" Hewey trailed off.

"It might be another Creepypasta," Sans said, a narrowed gaze watching the bus stop in front of them. "But it might be something else."

As the bus stopped in front of the two, the loud screech made both of them shiver where they were, a sense of unease filling the air. When the doors slowly pulled open, they creaked and groaned in protest from the movements, slightly hanging off of the old model of a transit bus. Although the bus was creepy and old, it somehow had a sense of welcoming to it, as if drawing him in. The feeling washed over Sans as he gripped onto his sons wheelchair tighter. Everything about the bus screamed bad, but he really, really felt like he should get on.

"I don't like this..." Hewey said in a hushed tone, pulling at his Dad's sleeve.

The darkness seemed to clear slightly inside of the bus, as if retreating down from the front allowing for Sans to see who was the driver. Hushed whispering seemed to drift through the open door, Sans unable to determine what they were saying. Everything felt so creepy and wrong about this, yet his legs felt as if he needed to get onto the bus. His bones felt tense, his soul screaming something, almost deafening out the whispering. It had felt as if the whispers themselves were somehow wrapping around his soul, trying to drag it forward into the dark trap before him.

"Dad, dad, dad!" Hewey hissed repeatedly, his voice trembling as his body did.

The driver simply sat, staring down at Sans. Looking at them made his skull go foggy, he could barely orientate what they looked like. Black or brown hair? Whips of hair was there for sure, but the color and length just seemed to slip from his mind. Black clothes, yeah. Definitely black, maybe some red? Or was that green? He felt like he might faint, his legs were wobbling. All he could tell for sure was that there was red eyes, with eyelids peeled back and a grin folding over their face in ways it shouldn't. Skin pulled back, twisting and folding in such painful ways Sans was glad he didn't have skin. It looked like their skin was cracked, sticking out in different places, an uneven terrain of pulled flesh and bulging eyes.

His voice felt choked. Hewey was starting to breath quickly.

"Dad dad dad-" Hewey repeated over and over again, voice cracking as he frantically pulled at his Dads hoodie. "Dad dad dad dad-"

Sans' grip tightened further. "Stop it."

Hewey finally managed to tear his eyes away from the thing in front of them and looked at Sans, but his father hadn't directed that at him. Oh no, he was directing it at the driver.

"Stop what you're doing," Sans forced out.

His teeth started to clatter. His chest felt heavy with a sense of fear, fear that managed to keep his legs rooted against the floor. The whispers insisted that he boarded, tugging at his soul. They were welcoming him, pressing further and further into his mind until it was as if he could only hear them.

"I said stop, you're scaring Hewey," Sans hissed.

The driver reacted, tilting their head until the crack of a bone could be heard. They continued until their head was at a perfect angle, bones snapping, each break sending another shudder down his spine. The whispered became slightly louder, and Sans started to recognize them. He felt tears start to creep up as the voices persisted.

"D-Dad, that's... that's the o-others," Hewey choked out.

His kids, his own d*mn kid's voices. His husbands and wife, his friends, all of them. All of them insisting that he board the bus, pulling him forward. Begging him, that's what they were doing. Begging for help, Addy's little voice crying out. Saying they needed him. Begging him for help.

But there was just something wrong about their voices. They sounded the same, but hearing them didn't sound right. At this point they were drowning out Hewey, whose face was flushed white and had trembling lips.

They continued, the voices did. Saying how they needed Sans, saying they would die.

It was obvious at this point. The driver wanted him to get onto the bus.

"If anything happens, Hewey, I'll use a shortcut," Sans said, voice wavering. "Stick with me kiddo."

It was okay, Sans had the backup plan of his magic to get him out of sticky situations. It would always be his last ditch effort, only the void itself could really cancel out the powers of his own void powers. Sans couldn't just turn away when something could have happened to his family, and his legs felt like they wanted to walk forward.

Looking down at the stairs, he found that the scraping sound hadn't been just from the door. A stairs had folded up into a ramp for the wheelchair.

The driver wanted both of them to get on.

"Hold my hand, okay," Sans whispered, reaching down to grab his son's trembling hand.

His legs were all too willing, the voices begging and encouraging. It was a silent threat, and both of them knew it. His family could be in danger, they wanted him to enter the bus. It was no mistake that they had put out a ramp and parked in front of Sans with the voices of his family, for all he knew one of them could be on the bus. Sans couldn't risk leaving with that threat looming over his head. With the taunting of his families voices, and the red eyes watching, Sans had no choice.

They climbed onto the bus.

《》《》《》

And there's my OC CreepyPasta!

It's just a bus pretty much. It picks people up in the middle of the night and they're never heard from again. So yeahh. It has this aura that makes people near it want to go onto the bus, so while both Sans and Hewey were freaking out, they still kinda wanted to get on. 

And the reason Sans got on was because it was sort of a silent, unsaid threat by the driver with the voices. Kind of like saying either "we have someone you care about" or saying "we know the people you care about, get the f*ck on or they might get hurt". So yeah, Sans got that and knew he could put up a really good fight, and knew that he could get Hewey outta there at the first sign of trouble, so he decided to play along at that point. I won't explain anymore because it'd be spoiling, so I'll keep it to why Sans got on the bus with his son, because they both knew it was a silent threat and Sans knew he could teleport out at the first sign of danger.
