3rd Person POV
~~~

Sans' eyes widened. His blue pupils shrunken and shaking of what he was witnessing.

(Y/n) was ontop on papyrus, tickling him. The both of them were giggling like two insane patients.

" Oh, what about there!? Are you ticklish there?! "

(Y/n) teased.

" Oh, Nono! Stop it! "

Papyrus laughed, clinching his eyesockets shut.
He tickled her back, (Y/n) laughing uncontrollably.

" You stop it! You're gonna make me pee! "

Both of them having tears of joy in their eyes.
Okay this was hurting.

" AHEM "

Sans had finally made his presence known.
(Y/n) stopped tickling papyrus and looked up at him.
She jumped off of the bigger skeleton and greeted them.

" Hi, Blue! How was your day!? "

She asked.
Papyrus sat up chuckling, still having the giggles from their 'friendly' tickle war.
Blue twitched a bit before realizing his queen was asking him a question.

" Oh it was alright! Training was great! How was yours?? "

They asked with a big smile, bags forming under his eyes.

" It was good! I had Papy to keep me company! "

You said happily, looking back at the taller skeleton.
Sans cringed at the nickname.
Sure, you weren't the first to come up with it but, pet names were a sign of liking someone.
And Sans didn't even want (Y/n) to consider anybody besides him close to her, let alone a friend.

" T-thats good. D-dinners ready. "

It was hard to hide the heaviness in his voice but (Y/n) didn't notice anything.  Sans was feeling a sudden slash of betrayal.

" I can tell! Smells yummy! "

You said walking passed him, down the stairs.
Papyrus fixed his sweater, pulling it down.
Sans stared him down. Papyrus felt the pair of eyes. He looked up at his brother and raised his brow.

" What? "

He asked.

" You know what. "

Sans said, his usually cheery aura replaced with a menacing gloom.
Papyrus sighed.

"Sans. This is too much. I feel as if you're growing an obsession with the human."

Papyrus explained.

" So what? I found her! She's mine! My human! Not yours! "

Sans argued.
It reminded Papyrus of when they were younger and would fight over the silliest reasons.

" She's not a shiny toy Sans. She's a human. That's worse. "

Papyrus stated.

" What if Alphys finds out about her? What then? "

Sans didn't say anything. He just pouted.

" I'll think of something... "

He mustered.
Papyrus closed his eyes shook his head. He sighed in frustration.

" Sans are you like this because of a silly little crush? "

He finally asked the big question.
Sans blushed a dark blue.

" Well- I...I wouldn't say crush- I just really really....like her... "

He finished blinking.
Sans had realized what he really wanted. At first he saw the human as a friend till the end, someone who would be loyal to him no matter what.
But now he see's that he wants more than a best friend. He wants...

" (Y/n)? My date? My girlfriend? My wife?! "

He asked himself aloud.
His blue pupils turning into hearts.

" Oh no...Oh no! Sans that wasn't what I was trying to say! I was just asking- "

Sans interrupted with his twisted romatization.

" Wowzers! Me being with my human...our souls binded for all eternity? "

He said to himself.
Sans REALLY like the idea.
Papyrus? Not so much.
Papyrus shook him, snapping Sans out of his little fantasy.

"Sans! Being friends is one thing! Being married is a whole other meatball!"

Papyrus tried to warn.

" Oh...I see... "

Swap glared at his brother.

" Y-you do? Then what's with that weird look? "

Bags formed underneath Papyrus' eyes.

" You're just telling me that so YOU can marry her! "

He accused.

" Whaaat?? Sans that's ridiculous! "

" Don't deny it brother, I've figured it out! But you better stay back because I had a crush on her first! "

He argued.
Papyrus rolled his eyes.
Blue, gave the floor a quiet stomp punctuating the end of this conversation.
He smiled to himself, ' winning ' the argument. He walked down stairs to join the human.
Walking into the kitchen, an even bigger smile of his face.

" How's the food human?! "

He asked, serving himself and sitting down next to her.

" It's delicious! Thanks for dinner! "

You beamed, taking another bite with Sans' special fork.

He blushed deeply admiring your radiance as bits of food got on your face.
Papyrus sat down as well, his appetite somewhat lost because of the recent argument.
Papyrus looked at his brother, with exhausted eyes.
He scoffed at how pathetic his brother was being.
He has had a few girlfriends in the past but papyrus has NEVER EVER seen such puppy love delusion coming from his own older brother.

What was so special about her?
What was so special about being human?
The most papyrus could understand was that you were different.
He shifted his gaze to you, trying to find any sort of attraction to you.
When he looked at you all he saw was...human.
Like how when humans looked at animals all they see is...an animal.

Papyrus shook the thought of comparing beastiality knowing that was completely different.
He straightened his back, yours and sans' voice muffled by his own thoughts.
He cringed abit before looking at you again, this time looking past appearances.

Okay, she's uhhh humble I guess...
She's friendly... which is FINE.
She's also abit of a goofball.
I'd say her sense of humor is pretty... good.

Papyrus blinked, feeling a sudden warmth in his chest.

' What the hell? '

He thought to himself.
The longer he looked at you the warmer his chest had gotten.
What's going on??
What's happening to me??

His pupils suddenly turned heart shape as he reminisced about the day you two had, full of jokes and humorous banter.
Is this what Sans see's in the human?
Papyrus thought as (Y/n) finally made eye contact with him.

"Is everything alright Papy?"

She asked.
Sans flinched at the nickname once more.
Taking a few gulps of water to moisturize his suddenly dry throat.

"Everything's perfect dollface~"

He responded dreamily.
Sans spat out all his water.

"WHAT DID YOU JUST SAY?!"

He raised his non-existent brows, furious at the younger skeleton.
Papyrus wasnt even paying attention, he was still looking at (Y/n) his dream-like state was gone and was replaced with erupted laughter.

" What are you... "

Sans looked at (Y/n) her whole face being drenched a mix of water and blue glowing monster saliva.
Blue covered his mouth, gasping loudly.
He apologized a thousand times, grabbing napkin to wipe you dry and it worked! Except...

Blue gasped again, your whole face dry but now glowing blue.
He again apologized a thousand times. You assured blue that it was no big deal.

" It's fine Blue! I'll just take a shower! "

You said awkwardly, excusing yourself and walking upstairs.
Blue buried his face in his hands internally screaming. Papyrus's laughter echoing throughout the house.

" How can you be laughing?! I've never been so humiliated! "

He yelled, his voice cracking abit.

" I-is THAT how you make your move on-on the la-ladies!? AHAHAHAHA! "

Papyrus mocked his older brother.
Blue groaned, trying to ignore Papyrus.

"I'll be right back."

Blue huffed, scooting out of his seat and going up stairs.

"Where are you going?"

Papyrus asked, wiping a tear from his eye regaining his composure.

" Helping my- I mean. Helping (Y/n)..."

He stated going into the bedroom and getting towels.

" Oh, let me help... "

He teleported to the 2nd floor.

" What? Noway! Finish your food! "

Blue hissed.

" I JUST want to help, stop being such a baby... "

He said back, raising a brow.

" BABY!? The Magnificent Sans is VERY MUCH mature! Thank you! "

Papyrus grabbed a hold of the towels, and gave a tug, taking them way from Sans.
In return Sans gave him a large gasp. He growled, suddenly blue magic surrounded the towels.
A force pulling them from Papyrus.
Papyrus glared at Sans, orange magic surrounding the towels now, together the magic created a brown color, they played tug-a-war, throwing unmeaningful insults at eachother.

" Ugh, You know how much I hate to play dirty! But you have left me no choice! "

Sans said, wanting this war to end.
Sans summoned a bone and wacked it ontop of Papyrus's head.
Papyrus' magic disappeared as they held their skull in defense.

Sans's smile grew as he tackled papyrus claiming the towels, while slamming open the bathroom door as well.
The two groaned in pain and looked up to see the forbidden sight of a human.
(Y/n) was half naked in her undergarments, face still glowing blue.
Sans's eyes wondered aimlessly up and down your body continuously admiring every last detail. On the other hand, Papyrus was still just as shocked as you.
After snapping out of her own embarrassed trance, (Y/n) quickly covered herself with her arms.

" H-HEY! GET OUT! "

She yelled begining to throw shampoo and anything else in the bathroom she can use as amo.
The two scrambled up and slammed the door closed, behind them, the two of them panting, both looking blue and orange.
The two exchanged glances, while still breathing heavily, they didnt break eye contact till, Papyrus gave a very exaggerated yawn, while 'stretching'.

" I gotta take care of something... "

He muttered, walking into his dark and messy room.
Sans could only guess that ' something ' had to do with below his belt.
He slid down the door still catching his breath from earlier.
He felt his soul, thumping and throbbing, begging to go out into he open, begging to express how it feels and begging for attention.
Sans forced it back into his ribcage, crawling to his own room.

He snatched his pillow and scream into it like some kind of mad man. Plopping down on his bed and staring at the ceiling.
His mind began to play more scenarios.
He imagined himself marching back to that bathroom and locking the door behind him.
Another one where he would ' innocently ' check on (Y/n) just to sneak a peek.
He thought of every option he had in that immediate moment to see (Y/n) like that But he knew realistically, the consequences won't be in his favor.

 His blue eyes glowed intensely, his soul leaving his own body. He stared at the glowing blue heart and thought twice before reaching up and grabbing it. He shivered at the touch, and proceeded to give it a little rub. He exhaled, closing his eyes and relaxing his body.
Unfortunately his 'me time' was over as soon as he heard the bathroom door close, followed by soft footsteps.
He snapped out of his trance and shoved his soul back in like he did before. He abruptly sat up on his bed, legs crisscross applesauce, hands resting between his legs.
You knocked on his door. He blinked and said

" C-come in? "

You open the door, still wringing out your hair in the towel they rudely given you earlier. 

"See? THATS what you're supposed to do instead of barging in!"

You said crossing your arms.
Sans blushed once more and thought up a lie. He couldn't let you know they were fighting over you.

" Well, it's always been just Papyrus and I living here, and we're both pretty familiar with skeleton anatomy so it's not as weird if we use the restroom at the same! "

He lied.

She just blinked at him abit confused.

He cleared his throat again.

" What I mean is, since you're going to be here for a while! Maybe the two of us should get naked and learn each others anatomy? "

He suggested innocently.
You threw a pillow at his smiling face, giving out a

"OOF"

" Nice try Blue, but I know you're not as innocent as you come off! "

She said in ' a matter of fact ' tone.
Blue pulled off the pillow, and put it on his lap

" H-huh? I don't know what you mean!"

He tried to save your perception of him.

" There's no need to lie! Papyrus told me, you've had a few girls in your room before! "

You said, hanging up the damp towel.

Sans thought about his past girlfriends. It's true he has had a few girls up here on his bed but, the farthest they've ever gone were intense makeout sessions.

" Sorry! But my brother is lying to you! Don't believe a single thing he says! He can be tricky at times... "

They warned.

" Besides we never even made it past '3rd base' as you humans call it! "

They defended.
You thought for a moment.

" 'As we human's call it' ? "

You asked, repeating his words.

" Ofcourse! Us monsters usually call it....um... "

He blushed a dark blue.

" Something else... "

" Soul Play? "

You both said at the same time. He jolted at your words.

" Oh my stars! Who taught you that?! "

His face engulfed with devastation.

" Ahahaha! Papyrus did! "

You laughed at his reaction, thinking the expression on his face was priceless. 
Sans found the situation anything but humorous.
His pupils changed from light blue to purple once more.

" What?! Papyrus?! He-??? " 

Was all he can muster out, his mind going a 100 miles per hour.
With all the flashes and busyness going through his head at the moment. There was one word, in BRIGHT red colors. Tainting his mind and only seemed to get bigger every second.

  B E T R A Y A L

He couldn't possibly believe that his brother would stoop so low as to teach his human about Soul Play behind his back!
He closed his eyes shut.
No- He could believe it... He just couldn't believe he was stupid enough to trust them alone with them...
Papyrus had a reputation of burning monster woman but he didn't think that extended to humans...

He tried to shake off this horrible feeling in his stomach.
He then tried to respond but all that came out was a croak, a voice messed up by the the tight dryness consuming his throat.
How cruel.
(Y/n) gave him a weird look.
He panicked some more not wanting to make a fool out of himself. He gulped down hard trying to moisturize his throat so he can speak properly.

" U-u-um "

he stammered and tripped over his own words.

" I'm glad Papyrus taught you that. Did he say or do anything else regarding that topic? "

Sans tried his best to sound cool, but his throat was strained.

" Well, he wanted to show me by summoning my soul! But we never got to it! "

You tapped your chin recalling today's events.
The sentance soothed Sans' anxiety but also made his blood boil.
Papyrus was doing it again...

" That's good! Soul Play is a VERY intimate thing honestly! It's best you do it with someone you trust with all your heart and soul! Someone who's always there for you no matter what! "

Sans was hoping he was getting his point across.
(Y/n) thought for abit before blushing.

" Ugh! So he WAS tricking me! "

You huffed, facepalming.
Sans was satisfied with that response!

" Yeahhh, My brother isn't that reliable! Harmless! But is constantly pranking all monsters! Mwehehe! "

Technically, Sans WASN'T lying about that.
He turned to you, your hand still resting over your eyes.

" Hey... (Y/n)... It's alright! I'm sure he didn't mean anything malicious... "

Sans put a comforting hand on your shoulder. You sighed and smiled at him before yawning.

" Anyway, You seem tired (Y/n)! You better get to sleep! "

Sans advised. You gladly listened, laying down on the blankets Sans had been sleeping on these past few nights.
He was about to protest but ultimately decided to just let it go... for now.

" Good night Sans... "

You smiled, allowing yourself to begin dozing off.

" Sweet dreams, My friend "

They hummed, smiling down at you.
This time Sans didn't even wait for your snores to come. He sat on his bed staring dead at the wall, the other side being Papyrus' room.
His conscious argued with one another. He pondered on whether or not he should let this slide.

' Papyrus will take it too far! He always takes it too far! '

' He will take her away from me '

' He's going to hurt her '

' How dare he treat her like a joke '

Sans knew of his brother's... not nice behavior. His laziness always got the best of him and he ends up hurting people without giving a shit...

Maybe in another timeline he'd threaten his brother.
Maybe in another timeline he'd kick him out of the house.
Maybe in another timeline he'd hurt him really bad.
He shooks those terrible thoughts out of his head.

' Whatever! He talked about Soul Play and put his filthy hands on her! No biggie! It's not like he actually took advantage of her or hurt her or forced himself on her! It's fine! Everything's fine! '

The more he lied to himself about how he felt the more intense those feelings became. He smiled widely at the wall, bags forming under his eyes.

' I love my brother! And he loves me! He wouldn't hurt me or my dear (Y/n)! '

He nodded ecstaticaly, trying his best to calm down.
His body shook as if it were shivering.
Sans just laid back, staring at the glow-in-the-dark stars he taped to his ceiling long ago.
He inhaled deeply, closed his eyes and just thought of you.
Your smile, your face, your kindness....
Just you...
He eventually stopped shaking and was able to think about his brother without having an aneurysm.
He rested a hand over his soul.
If just the thought of you can calm him down this quickly... it must be fate.
