****** Brother ******

Summary
     Papyrus finds his baby brother missing four days into his heat. What
     will the swap Papyrus do to get him back I wonder?
Notes
     I don't remember the name of the fic but it got creepy and had rape
     so I made a sequel that was worse. It was where Swapfell Papyrus took
     swap sans during his heat and so now here's the continuation that is
     worse. All of this is triggering so be careful
See the end of the work for more notes
Brother
It had been days. Papyrus had known when his brother went into heat and it had
been days since that started. Normally monster heats lasted only a week or so
and four had passed. Papyrus groaned in frustration. Normally he tried to leave
his brother alone for the duration of his heats. He would stop in once or twice
during the time to check on his brother. It was a thing of courtesy for Sans
and also to stop himself from taking advantage.
He loved Sans, more than anything. Each night he would do things on his own or
even just get hard thinking about his brother. That shining hope in his eyes,
his desire to help everyone. He loved all of it. But he couldn't get hard now
because fear pulsed through his veins.
It was day four and there was no sign or smell of his brother. That meant that
someone had taken him. His poor little baby brother. The images flooded his
head. Some other monster pounding him mercilessly. Taking him. Stretching him.
M a k i n g h i m s u f f e r. And he couldn't take that.
His darling baby brother who was going to become big and strong as a guard
member before settling down to have a family. He was aiming so high and now
someone had taken that from him. Papyrus could feel it, and that person was g o
I n g t o b u r n I n h e l l.
Slim stretched happily. His two mates looked so cute swollen with his babies.
Blackberry had long ago accepted it and was a very nice mate to him actually.
Almost like a female wolf. Little nips of love to his legs and tail whenever he
didn't something wrong and a strong growl. He was perfect, and that was why
Slim had bit him. He wanted a mate like that.
But then going through the woods he had smelled a delicious blueberry scent and
chased it to his newest mate. He had been hesitant at first but then begged him
for more. He even tried to reassure Slim of his pregnancy in case he was
worried. He did tend to cry a lot though. Slim knew the feeling though. Not
being able to share the news with one’s pack was very sad indeed. He had
smelled a few familial scents on the Blueberry though. He knew that sometimes
offspring were rejected so he couldn't let him leave his cabin.
Bang
The door busted in loudly and a tall skeleton stood at the door. Slim was
instantly between the intruder and his mates. “You won't take them from me!
They're mine!” Slim growled like an alpha wolf.
The intruder simply chuckled with his eye lights shining brightly. It was like
Slim had just told the funniest joke in the world. “You seem to be mistaken,”
the stranger laughed. “You have something that belongs to me,” he said simply.
Slim growled and threw a wall of bones at the monster. He dodged out the door
and threw a few attacks at him. Slim dodged them easily. This monster was no
match for him! He charged forward ready to attack when a cry of pain caught is
attention. It was Blackberry who was clenched around his heavily swollen belly.
A large bone spear was lodged deep inside of it and the pups- the pups were so
dead! He growled feeling his rage growing. They didn't deserve this. They
weren't even born yet.
And that's when the bone dissipated.
Sans awoke to shaking from Blackberry. He found it odd how the other’s ecto
body had dissipated. “Where are the pups?” He asked without thinking and not
really wanting to know anyway.
Blackberry grinned back. “They’re gone. So is the bastard who did this to us,”
he replied. “Hey look at yourself kid, you're fine too,” Sans looked down to
see his ecto body gone. That's when he noticed the magical fluid spilled across
the floor. His was a soupy blue while Blackberry’s was a crusty red. Sans
almost puked when he realized that all of the pups inside of his red eyed
alternate had dusted on exit. He vomited with that realization. All of those
potential lives were destroyed just for their freedom.
Once he was done, Blackberry patted him on the back. “Let's grab a shower real
quick and get the fuck out of dodge,” Blackberry told him. And he did mean
fast. Sans only got cleaned with a washcloth and some of the warm sink water.
Then he was back in his guard uniform and they were walking in a random
direction in the snow. Then they back tracked and created a branching path.
Then they went back and branched off of that. They kept doing it for a few
hours before they eventually just kept walking one direction. Without
backtracking. They walked for about an hour before they made it to the river.
Not much after that they found the river person. “But we’re by snowdin,” Sans
protested.
“He’s going to search for us, we have to lie low,” Blackberry explained. Sans
nodded in response. “Hotland please,” Blackberry told the river person. They
nodded as the two skeletons climbed aboard.
Papyrus victoriously stood above a pile of dust. “Please just spare me and my
puppies,” Slim cried. Papyrus couldn't help but grin as he ripped him apart
bone by bone until the ground was stained with marrow and the screaming had
stopped.
It had been worth every second on effort. The mutt had fallen for his trap and
chased him into the woods. Sans thought he never listened but oh boy did he. He
built a trap to capture that would have made his bro proud.
But now it was time to return the hero. He just had to clean up first so that
his bro wouldn't be scared of him. So he teleported into the bathroom and
removed his clothes. He slipped into the shower to scrub the evidence of his
sins from his body.
“W-what?” The raging dog’s ears fell flat as he made a shocked face. His limbs
were bound tight and pulled away from his body. He couldn't pull away because
of the strain that would put on his neck. Even his tail was caught in a metal
clamp which bled orange with marrow.
“You thought you were the hero, saving poor little monsters from heat.
Impregnating then with your little r a p e babies,” Papyrus growled as he came
horribly close.
There was deep rooted fear flashing in those beastly eyes. “You're a strong
little wolfie aren't you?” The skeleton vigorously shook his head as his eyes
screamed no. Papyrus grinned. “I'm going to break you how you broke Sans and
then make it ten times worse,” he growled.
And that's where the other’s downward spiral of agony began. He pulled a knife
out of his pocket and ever so gently cut into the wolf’s shoulders. As he cried
out in pain, Papyrus bit him. He teased the other into a mess of heat and
nerves as he left little cuts and nicks along bones and fur. But just as the
other reaches the peak of arousal, Papyrus plunges the knife deep into his
butt.
The dog screamed and begged him to stop as the blade was plunged in and out.
His magic poured from the abused orifice as the other monster pleaded for him
to stop. He could have. Papyrus had every opportunity to walk away, but he
didn't. Instead he made it worse for the other. Growling into his ear about all
the pain he had caused his Sans. How the innocent little blueberry had begged
him to stop but he had caused his brother pain like this.
When he felt the monster couldn't take much more, he grabbed a screwdriver from
his pocket. It was just a little flat head used for small screws he would
tinker with on his machines, but sharpened to a point in case ice was where it
shouldn't be.
So he shoved the screwdriver deep into where it shouldn't be. The Wolfy
skeleton cried out in agony as his dick was shredded from the inside with
Papyrus’s movements. The wolf quickly tried to dispel his organ, but to no
avail. Some of the liquid from Sans’s heat was still on him. It made it to
where he was helpless to stop this. And Papyrus enjoyed that. He wanted this
bastard to feel all of his brother’s suffering in his final hours of life.
Papyrus realized that the shower had gone cold and he was still just scrubbing
away that bastard’s dust. He checked his now mostly clean bones that had come
from nearly an hour of scrubbing. No, now was the time to retrieve his brother.
So he short cutted back to the cabin. Much to his surprise it was empty. He
could see the crusty magic from the unborn children he’d slaughtered earlier
and some other magic that looked like his brother’s. He hadn't gotten rid of
that one. Did that mean the other skeleton had?
Papyrus searched the floor for more dust and even the snow around. The other
skeleton being kept here had popped his brother’s belly without killing him,
and by the prints in the snow even hurting him. Perhaps the other was a stray
or survivor that the dead rapist had picked up. He definitely looked like one
from the gutters of society everyone pretended not to know about. Papyrus
thought that it might be a good idea to keep him to. Make Sans see him even
more as the benevolent older brother who always had his best interest at heart.
He really did, but sometimes it was nice to make his brother love him a little
bit more, and this piece could bring him close to capturing all of his
brother's heart just as the tiny skeleton had captured his.
Sans was dragged into a shabby little lean to shelter. They had traveled for
hours, first through the town and then even deeper underground. They had
climbed through a crack in the wall that led to the old architecture. Before
the new city could be built, some digging monsters had expanded on the ancient
homes hidden there. And they were crawling with all manner of rough looking
monsters. Most looked terrifying with LV of five or higher. Others cowered in
the corners and grabbed what scraps they could. Some wore skimpy clothing and
sold themselves to monsters who looked like they wanted to dust them.
Blue couldn't help but hide next to blackberry. Everything was the opposite of
what he believed in. No one helped here, there was only harm. “I want to go
home,” he whimpered.
“You can't. If he hasn't found you yet then that means he doesn't want you,”
the blackberry growled. Blue saw a flash of menacing orange as a hand dropped
onto Blackberry’s shoulder.
“I think you're wrong pal,” Papyrus’s face was now relaxed back into that same
lazy expression. His eyes stopped glowing and he looked perfectly fine. It was
his brother.
“Papy!” Sans cheered and jumped into his arms. Papyrus caught him happily and
held him close.
“Let's go home,” Papyrus said with a knowing wink at the Blackberry. The
skeleton shuddered, remembering the scene from before but could do nothing as
they were blinked away to the skeleton brothers’ house.
