They go into the Observation Deck

“…not really in the mood to be observed, but fine. Let’s go.” The two half-naked girls opened the door.

“Starting here from next year, eh kiddo?” A gnomish-looking elf talked to his younger co-worker. His beard reached well into the ground, while the newest hire was still growing out of his stubble. They were sitting behind a giant computer. In front of them was an empty room separated by a glass wall and door. “Don't worry, I'll show you the ropes.”

“I'm one hundred years old, but whatever,” the brattish elf rolled his eyes.

“Here at the observation deck we determine if a human has been naughty or nice. This room lets us spy directly into the human world to see how they behave.” The old elf pushed some buttons. A Christmas gathering appeared on the other side of the glass, a human family was enjoying dinner.

“Excuse us!” Kim and Harako came running out of the door behind them. “Crap, a dead end!”

“Found you!” Guaria sprinted behind them. “Oh, I'm going to have fun dragging you two out!”

“Look, there's a door there!” Kim and Harako ran across the glass door.

“Oh no, you don't!” Guaria followed them as well.

The old elf coughed while his junior stared in disbelief, mouth agape. Did three half-naked tall women just run into the room? “Anyway, if you want to make a hands-on observation, you must always bring your invisibility cloak or the humans will be able to see you as clearly as you can see them.”

The young elf closed his mouth. “So does that mean that-“

“Oh yeah, those humans are going to see some tits very soon.”

A fork dropped on the wooden floor. The family dinner was interrupted as everyone turned to stare at the intruders that appeared in the corner of the dining room. Two younger cousins hi-fived each other, their grandpas shaking their heads in disapproval. A mother was quick to cover her sons' eyes, even though he was old enough to drink.

The three half-naked women backed away into the corner of the room, with Kim standing in front by sheer bad luck. Even Guaria was confused by the situation and stopped her chase.

“Who the hell invited strippers to our Christmas dinner!?” the oldest matron stood from the table, a woman whose skin had so many wrinkles it resembled a topographic map. Around the room, the rest of the family shook their heads and muttered a thousand variations of "not me".

“Excuse you,” Kim said indignantly. “ We are not strippers! And hey! You! I see you boy! No pictures!”

“Oh, so you just like to break into random houses looking like a slutty Christmas tree?”

“N-no, I can assure you there is a logical explanation-“

“Did you take that gift box from our tree?” Another old woman approached Harako and latched onto the cardboard box. “That was for my grandson, how dare you!” She pulled the box, and Harako pulled back to preserve what little modesty she had left.

“N-no… stop!.... this is my box!”

“Technically, it's Santa's box,” Guaria said, leaning foward against a chair. Sure, she still had no idea what was going on or why she was there, but why not enjoy seeing the two intruders squirm for a bit? “Ow!”

Another grandma slapped her behind with a wooden spoon. “How dare you come to our house dressed like a prostitute elf!” The nonplussed woman grabbed Guaria's panties and pulled them toward the floor. “Stay still so I can teach you a lesson!”

“Ack!”

“Eep!” Meanwhile, the other matron succeeded in recovering the gift box, or at least the half of it that came free out of Harako's fingers. Her grandsons jeered, and the specter could feel her face light on fire. She meekly crouched and tried to cover up with the little square of cardboard she had left.

“And you give me back that ornament, young lady! That's no place for the Lord's crown,” meanwhile, a middle-aged woman forcefully yanked Kim's wreath up her arms. Once more, she was left wearing only her tinsel G string and the hat on her head.

“Eeep!” yelped Kim, hugging her chest and turning away from the boy's cellphones.

“Meep!” squealed Harako as an impish girl pinched her behind while she was busy holding her pathetic cardboard square over her front.

“Owww!” cried out Guaria, as her behind was battered by a wooden spoon. There was no Christmas Magic in the air, and the old grandma was freakishly strong. She could not find the strenght to push her away.
