InSaNiTy (fellcest), an undertale fanfic

prologue

He looked out into the forest pondering what might be inside. He had never been in there. His adoptive older brother had told him to stay out because in was dangerous but at the moment he could care less as he walked into the forest. His name was Sans WingDings before he was adopted by his brother Papyrus' Fonts family. Sans had adopted the names Fonts even though the family was abusive. He walked deeper into the forest to numb himself in the cold of the forest air. He felt as though he was going mad.

Papyrus was walking though the town of Snowden when he heard whispering. He stopped to listen to the whispers and he heard them loud and clear 'did you hear, did you hear' 'yea, yea i heard' 'I heard that brat Sans got adopted again by another family' 'what really, but isn't he a homicidal sociopath?' ' yea that's what I heard, I also heard that he killed 20 monsters in New Home before being adopted by the fonts' ' what? Wow his stats must be high' 'I heard the last monsters to adopt him were murdered in cold blood' 'what really?' 'Yea' 'I heard his birth father experimented on him' 'oh, that poor boy, maybe that's why he's a homicidal sociopath' 'Y ea maybe' all the whispers where of fake sympathy and of hatred and mockery in papyrus' eyes. He stormed out of Snowden town to sans' station. When he arrived he saw sans walk out of the forest with a blank look on his face and his eye light to the ceiling. He also seemed to be to being singing and papyrus lessoned

Target on my back
Lone survivor lasts
They got me in their sights
No surrender no
Trigger fingers go
Living the dangerous life

Hey, hey, hey
Everyday when I wake
I'm trying to get up, they're knocking me down
Chewing me up, spitting me out
Hey, hey, hey
When I need to be saved
You're making me strong, you're making me stand
Never will fall, never will end
Shot like a rocket up into the sky
Nothing could stop me tonight

You make me feel invincible
Earthquake, powerful
Just like a tidal wave
You make me brave
You're my titanium
Fight song, raising up
Like a roar of victory in a stadium
Who can touch me cause I'm
I'm made of fire
Who can stop me tonight
I'm hard wired
You make me feel invincible

I feel, I feel it
Invincible
I feel, I feel it
Invincible

Here we go again
I will not give in
I've got a reason to fight
Every day we choose
We might win or lose
This is the dangerous life

Hey, hey, hey
Everyday when I wake
They say that I'm gone; they say that they've won
The bell has been rung, it's over and done
Hey, hey, hey
When I need to be saved
They counting me out, but this is my round
You in my corner; look at me now
Shot like a rocket up into the sky
Nothing could stop me tonight

I feel, I feel it
Invincible
I feel, I feel it
Invincible

You make me feel invincible
You make me feel invincible
Shot like a rocket up into the sky
Not gonna stop
Invincible

You make me feel invincible
Earthquake, powerful
Just like a tidal wave
You make me brave
You're my titanium
Fight song, raising up
Like a roar of victory in a stadium

I feel, I feel it
Invincible
I feel, I feel it

He kept reaping that song over again as he sat down and closed he and looked like he was asleep but the only thing that said other wise was that he was singing. Papyrus approached him and he stoped singing and looked at Papyrus.
"Hello brother" he said with his fake smile that pissed Papyrus off to on end.
"We're going home Sans"
"What?" Sans asked with a weird look on his face.
"You heard me… now come" he said then started to walk home
Sans got up and followed him home. Their parent was never home only on special occasions like Papyrus' birthday which was last week. Even though his adoptive parent adopted him they didn't care for him but that was ok. At least that what he thought, infect his new parent cared for him, he just … just didn't know it. He even thought that his adoptive older brother hated him for some reason, but he just didn't know why. He felt alone like before. He was … always alone, alone in this cruel world he lived in … alone… alone … that word might drive him insane someday. Papyrus knew that Sans had trust problems and he tried to keep his distance so he wouldn't get hurt. The thing was Papyrus had fallen in love with Sans the moment he saw him with his father Chillby. He Didn't want Sans to Know but his urges had taken him and he did things to Sans that are wrong. He Knew that Sans didn't Know what it all meant, but he know that one day understand. They walked into the house and papyrus grabbed Sans' hand and led him to the couch. Papyrus slid down into the couch and wrapped his arms around Sans.
" w-what a-are y-y-you d-doing" Sans ask nervously
"Quite Sans" Papyrus said
I long for your embrace
Every single day
To meet you in this place
And see you face to face

Papyrus sang out in low voice as he pulled sans closer

Will you show me?
Reveal yourself to me
Because of your mercy
I fall down on my knees

Sans sang as he push himself further in to Papyrus' embrace

And I can feel your presence here with me
Suddenly I'm lost within your beauty
Caught up in the wonder of your touch
Here in this moment I surrender to your love

Papyrus sang

You're everywhere I go
I am not alone
You call me as your own
To know you and be known

Sans sang

You are holy
And I fall down on my knees

Papyrus

I can feel your presence here with me
Suddenly I'm lost within your beauty
Caught up in the wonder of your touch
Here in this moment I surrender to your love

Sans

I surrender to your grace
I surrender to the one who took my place

Papyrus

I can feel your presence here with me
Suddenly I'm lost within your beauty
Caught up in the wonder of your touch
Here in this moment I surrender:

Sans

I can feel your presence here with me
Papyrus ends the song

Suddenly I'm lost within your beauty
Caught up in the wonder of your touch
Here in this moment I surrender to your love

"Sans?"
"Yea?"
"Did you go into the forest?"
"Yea… I guess"

Papyrus and Sans fell asleep on couch close to one another. They were so close it was cute. Sans slowly woke up from sleep. As him opened his eye sockets he was scared all the way a wake by the sight of his older brother Papyrus holding him in his arms asleep. He fought the urge to kiss his brother in fear of punishment if he did. So he just lied there waiting for his brother to wake up… Wait…. Wait… Wait… that word was making him mad, insane even
Insanity…
Madness…
