Anyways... Enjoy and Merry Christmas :3
-----------------------------------------------------------

He's late. Undyne, Alphys, Asgore, Toriel, Frisk, Flowey, Chara, Papyrus and even Grillby is here, everyone BUT him... We had decided to throw the Christmas party at Toriel's and everyone except Sans even slept the night so that Santa could drop all their presents off at once. Papyrus said that he wanted to help him anyway he can and it was fun. My lazy boyfriend had said that he was busy for once and couldn't come until the morning. It's eleven o'clock.

"WHERE IS HE!? HE SHOULD HAVE BEEN HERE THREE HOURS AGO!"

"H-He probably is sleeping i-in again..."

"He promised me Alphys that he'd be here early and you know him and promises."

I sigh and stand up, going to the door and grabbing my jacket. I quickly throw on my gloves and scarf too as it looks freezing outside.

"I'm going to go get him."

"Tell the Comedian that he had better have a good reason why we have to wait for him or i'm gonna fill his room with spiders again."

"We agreed that you wouldn't kidnap Muffet's spiders again Chara and i'll tell him the rest."

I walk out the door and quickly throw on my hood, it's snowing again and i'd rather not have wet hair when I get back. It sticks to my back and Sans always questions why that's annoying, guess he would never truly know why. I stomp my way through the snow and quickly end up at the wooden house, covered in lights and even has everyone as snow sculptures out the front. Sans even made the trouble to make the shape of his head before falling asleep. I smile and use my spare key to get inside.

"Hello? Sa-... Oh my gosh what have you done?"

He is sitting in the middle of the lounge room floor, his face a large blue blush and his arms, legs and even his rib cage is tangled in (f/c) ribbon. He struggles a bit then slumps over, he must have been up for hours trying to get out.

"i... uh... tried tying a ribbon around your present with magic and it... somehow did this..."

"Somehow..?"

I give him a skeptical look, we both know that he can control his magic quite well, even under extreme pressure. 

"um... i uh... looked at themistletoeandthoughtaboutkissingyouunderit..."

I couldn't help but blush slightly while his doubled and now his face looks like a blue bauble that is looking down at the ground. Chuckling, I walk over and kiss his teeth, making him glow a little brighter before kissing back. I cup his skull in my hands as I kiss him while he just relaxes into it. Sadly humans need to breathe so I pulled back and smiled at him.

"You don't need mistletoe to kiss me Sansy."

"heheh..."

I see him wrapped up in the ribbon again and smile as I get an idea.

"Want to help me prank everyone?"

"that would an awesome christmas present (y/n)!"

An hour later we arrive back with all the presents that Sans had made 'last night', while in reality me and him made them in an hour. Everyone looked relieved when we returned.

"THERE YOU ARE BROTHER! WHAT TOOK SO LONG!?"

"sorry bro but i got a little... tied up."

He gently tugged at one of the ribbons which made several people in the room groan in annoyance while I laugh along with Sans and Tori. We hand them each of their presents and wait.

"opens yours first tori."

It was obvious that it was a frying pan as you could clearly see the shape. She unwrapped with a very small smile, that was until she saw what was laying inside the pan.

"One hundred and one types of pies!? Well thank you San-!"

She opens the book and a spring inside flings a whipped cream pie right into her face, everyone burst into laughter while Tori chuckled and licked some of it off.

"I can't believe you..."

"sorry, i couldn't resist."

She shakes her head with a smile and goes to the kitchen to clean her face. Sans uses his telepathy to open the door and bring in a big box inside.

"merry christmas bro."

"OH! SANS THANK YOU!"

He quickly opens it and finds a smaller box, he looks confused and looks inside to find another smaller box. Ten minutes later he's left with a small box that fits in his hand, he sighs and opens it and there's a VERY small bone inside.

"THANK YOU SANS..."

"only the best for you bro. your turn alphys."

She actually looks terrified. She very slowly and shakily opens hers and pulls it out, a jar of cut beetroots sit inside while a picture of Dre is taped to the top. Her face turns unimpressed and glares at him.

"what? everyone loves beats by dre..."

"SANS, ARE ALL OF YOUR PRESENTS LIKE THIS?"

"no, chara's is different."

She gives him an evil glare as she throws the box onto the ground, then stomps over to him.

"I am NOT going to give into your stupid pranks today Sans! Your ruining Christmas for everyo-... What is that..?"

She looks down to see an army of spiders crawling up her leg, she screams and runs outside to roll in the snow.

"justice. a gift from me and muffet."

"Sans no one else is going to open your gifts. Keep them you lunatic."

"SORRY BROTHER, BUT YOUR GIFTS AREN'T REALLY... JOLLY THIS YEAR..."

Sans suddenly gets a disappointed look and looks down, I can't help but feel bad for him so I grab onto his hand but he pulls away from me.

"fine. i'll go to frisks room and take away all those gifts too..."

"Huh? You had gifts in my room Sans?"

He stands up and sadly walks towards the stairs, talking as he walks up them in an even sadder voice.

"doesn't matter. you won't like those either..."

He disappears into his bedroom while gets guilty looks, I just feel bad now. I sigh and stand up to go to the stairs.

"Good job guys."

I stomp my way up and follow him into Frisks room, slamming the door behind me as silence follows.

~~~~~No One's POV~~~~~

The group all sit around the lounge room and stare up at the bedroom. Frisk is the first to stand up just as Chara walks back in.

"Where did the Comedian go!?"

"Calm down Chara, he was just trying to play a joke. On everyone but you."

"He knows i'm scared of them Frisk!"

Frisk shakes his head and gets his determined look, making Chara groan as she knows what's going to happen.

"We're going to apologize aren't we..?"

"Yes!! Now everyone come on!"

They all did get up but they still look guilty, not as enthusiastic as Frisk was about apologizing to Sans who they all know has depression already. Blame Chara for that. They all walked up to Frisk's room to see that the door was slightly open. Papyrus was the one who slowly pushed it open then turned on the lights in the pitch black room. It was filled with presents, the floor was unwalkable, the beds were covered and Sans was laying in the middle of all of it in a hammock with (y/n) beside him. Both smiling brightly.

"merry christmas guys. it's sans-tastic isn't it?"

The group were all too surprised to groan, even Papyrus had his jaw as far down as it can go without it falling off completely. 

"SA... SANS... WHAT..."

"i wanted to make this an unforgettable christmas so i did this."

"But it was my idea for him to prank him. Mettaton would be jealous of our acting skills..!"

After a few more seconds of awe Sans rolled the glims in his eye sockets before using his telekinesis to bring all the presents downstairs, including the hammock he and (y/n) were on. The whole time the group were unwrapping them he was asleep after using so much magic but everyone understood and let him sleep. (Y/n) leaned over and kisses his forehead.

"Merry Christmas Bonehead..."

And in return they were crushed by a skele-hug by their sleeping boyfriend, tipping them out of the hammock and jolting him awake.

"wh-what happened!?"

(Y/n) just laughed and hugged him back, kissing his teeth for a second before deciding to just lie on the floor. What a great Christmas, finding him tied up in a little bow in the morning was probably the best present this year.
