Narrators P.O.V

You were sweating so as Sans too.... You keep shouting from the pain that Sans is giving you and moaned for him to stop but he was sooooo DETERMINED to finish it.

"Sans.... P-please stop~" You said moaning a little.

"Nope" He said continuing at what he is doing while on the other hand SOMEONE was listening through it all.....

~Outside~

"C-Cross! This is really I-Inappropriate thing to do!" Chara said blushing.

"Hush! Chara! This is really good to hear!" Lust You quietly yelled at him hanging her tongue seductively.

"I wasn't talking to you!" Chara also quietly yelled.

"Yeah, yeah! Whatever" Lust You said looking at the door knobs key hole.

"OooOoo~ this is really interesting to see~" She continued sarcastically.

What she see is you were on the bed being pulled by Sans with a corset on your waist while you both are sweating you shouted because he was pulling the corset really tight but why did you moan? It's because you were trying to stop him by saying something really sweet.

"I'm outta here this isn't fun anymore" Lust You added whipping her hair to the side.

"Ok..." Cross said rolling his pupils.

"Yeah she's right I just saw what's in the inside......" Chara said with a poker face.

"What?!? Tell me please? Pretty pretty pretty please? With a..... Chocolate on top?" Cross said doing a puppy dog eyes while Chara is fanboying in the inside.

"We'll they were...."

~Inside~

"There! Done! That wasn't so bad right?" Sans said playfully.

"Wasn't that bad?" You said while Insanity is taking over making you shot up as a ghost.

"WASN'T THAT BAD!?! YOU ALMOST FUCKING KILL ME WITH THIS, THIS SHIT AND YOU TELL ME IT 'WASN'T THAT BAD'!?! YOU HAVE SOME GUTS TO TELL ME THAT-!" Insanity said but stopped when he realized something making Sans chuckle.

"Did you spread your 'Punphobia' in me? Because if you did you'll never see the light ever again!" He continued suffering from the 'disease' Sans have given him.

"Awww~ come on sweetheart don't be such a suffering kid ok? Plus...... GET OUT OF MY Y/N'S BODY YA LIL' SHIT!!!" Sans said his eye socket turn black while his smile grew wider while his razor sharp teeth grew sharper and sharper by the minute making Insanity gulp and left your body.

"You know Red you don't have to do that it scared the living shit out of me....." You said not realizing what you said.

"Sweetheart where did you learn the word 'shit'?" Sans asked returning to his normal face.

"From you and Lust me! Why?" You said in the end by asking him.

"Oh nothing..... Brb k kid?" Sans said using the 'Brb' excuse.

"Ok...." You said pouting while Sans pat your head.

"Good girl!" Sans said teleporting to 'somewhere' if you know what I mean ;) if you don't know his teleporting to Alphys to have a word with her.

"Ummm.... Bye?" You said to no one in particular sighing you went to your closet and pulled out a pirate costume.

"Well..... For my size it's perfect! But people would also think that I'm a kid considering my...... size" You mumbled while blushing putting it on.

"This is kinda embarrassing....." You said looking at the mirror.

Your P.O.V

"Well it's not embarrassing considering your wearing it~" I turned around and saw Sans with a cigarette on his teeth.

"HEY! NO SMOKING! PUT THAT DOWN THIS INSTANT YOUNG SKELETON!" I yelled looking at him while topping my boot on the ground rapidly.

"Heh.... Your not my mo-!" Sans said but I cut him off by kissing his cheek while his face turned into an apple color blush.

"Mmm~ you taste really good~ what type of soap did you use?" I said licking my lip what? IT TASTE LIKE F/D!!! WHAT DID YOU EXPECT ME TO SAY!?!

"Umm..... Just a plain f/d that I just ate at Alphys to bad though they ran out of it" He said scratching the back of his skull I pouted and went outside the door to see Cross and Chara with a poker face.

"Umm.... Hi?" I said sweat dropping.

"So you want to come with us trick or treating? We might get a lot of candies and chocolates" I said to them while Chara nod his head rapidly while Cross just did a simple nod.

"Ok let's go!" I said running to the door with my pumpkin with me I smiled and waited for them to come.

Let's just say that today's Halloween is fun considering Chara ate a lot of chocolates while Cross tried stopping, Sans trying to get out of the people who thought he was wearing a costume, Papyrus for once is getting along with the kids buuuuttttt ehhhh not the adults and I was with Lust me considering she wants to teach me the 'naughty' side and how to get to the 'Bone-Zone' with Sans which really interests me!

👻HAPPY SPOOKY HALLOWEEN EVERYONE!!! Even though it's not Halloween yet but hey! At least this is just an advance Halloween anyway Happy Halloween everyone may your nightmares come true!👻
