Summary: This is a "I Saw Mommy Kissing Santa Claus" kind of story. The Grissom twins witness Sara kissing "Santa", and more, and decide the fat man must go down.

Chapter 1

7:30 Friday Night, less then a week before Christmas.

"I look ridiculous in this thing." Grissom moaned.

"Oh you do not, you look adorable." Sara said as she helped Grissom adjust his fluffy white beard. Tonight was the lab's christmas party and a week earlier names were thrown into a hat to see who would be the lucky person to play Santa. Guess who was the lucky winner.

"Adorable?" he questioned back.

"Handsome? Debonair?....Sexy?" Sara finished with a seductive tone and a wink of her brow. Grissom arched his left brow and smirked.

"Well....maybe this won't be SO bad."

"Tell ya what Santa, if you're a good boy tonight we'll play some reindeer games when we get home." Sara said with a sly smirk.

"Oooo Santa likes the sound of that." Grissom replied as he pulled Sara in tight for a kiss.

Just as their lips touched, 6 yr. old Keri walked around the corner rubbing her sleepy eyes. She stopped short at the site and quickly ducked back around the corner.

"NO!! That couldn't be....Santa?....kissing mommy? No way!! I must have been seeing things." she thought to herself as she rubbed her eyes again. "Mommy said Santa was coming down from the North Pole early to check on kids and get last minute christmas wishes but he NEVER comes to our house till christmas eve. Besides, mommy loves daddy. She'd never kiss Santa."

She had to look again. Slowly she peeked around the corner....no one...."Nah, it couldn't have been. I must have been seeing things."

She walked into the kitchen to find Sara washing dishes.

"Mommy?"

"What are you doing up baby?"

"I was thirsty, could I have a glass of milk?"

"Sure baby." Sara poured the glass and Keri gulped it down. "Thanks mommy....where's daddy?"

"He took Bruno out back for a potty break before we leave for the lab party. Mrs. Roberts will be over any minute to watch you girls while we're out. Now get back to bed ok?"

"Ok mommy, goodnight"

"Goodnight baby"

Keri climbed up the stairs and crawled back into bed, her twin sister Gina asleep in the other bed.

3:36 a.m.

Gina sleepily opened her eyes, the urge to use the little girls room waking her from her sleep. She quietly slipped out of her bed and tip-toed towards the door so as not to wake Keri. She tip-toed down the hall, knowing her parents would be home now, asleep themselves, and not wanting to wake them either.

As she approached the bathroom she could hear noises coming from her parents' room farther down the hall.

"HO HO HO" she heard a deep voice say.

"Santa?" It certainly didn't sound like her daddy's voice.

"You've been a naughty naughty girl Sara. Santa's gonna have to punish you." the deep voice said next.

"WHAT?!!" Gina thought to herself as she scurried to her parents' bedroom door. The door was slightly ajar so she pushed it open just enough to peek her head in. Her eyes grew wide with the sight in front of her.

There on the bed, naked as a jaybird, was her mother. Her hands tied to the headboard behind her head. On top of her was Santa with his white hair, fluffy white beard, and red hat. The rest of him as naked as her mother. Gina thought her mother looked like she was in pain cause her eyes were closed, she had a funny look on her face, and she was moaning.

"What is he doing to her? Why is he hitting her belly with his belly? and where's daddy?"

Gina feared for her mother's safety.

"I gotta stop him. I better get Keri, I can't stop him alone."

As quietly as she could she returned the door to its original position, so as not to alert Santa to her presence, and rushed back to her room as quickly and as quietly as she could.

"KERI!! KERI!! WAKE UP!! SANTA'S HURTING MOMMY!!" Gina frantically spoke as she shook her sister.

"What? What?" Keri replied with a start, "What are you talking about?"

"It was awful. Santa's hitting mommy with his belly and he's got her tied to the bed and nekked. We gotta stop him!!"

"Where's daddy?" she asked as she hopped out of bed.

"I don't know, maybe he did something to him." Gina replied worriedly, "We gotta stop him." Gina grabbed Keri's hand and rushed back down the hall. As they got to the door they paused. Gina faced her sister and arched her brow the same way Grissom would.

Noises were no longer coming from the room.

"Oh No!! Maybe he killed mommy and left!!" Gina exclaimed wide-eyed.

Both girls quickly pushed the door open and rushed in. They looked towards the bed and sighed with relief. In the bed, with the covers wrapped around them, were their parents both safe and sound and asleep. Grissom holding Sara tightly to him.

"Where's Santa?" Keri asked.

"I don't know." Gina replied, "maybe daddy showed up and took care of him."

Out of the girls' sight in a chair rest a red suit. A white beard, white wig, and red hat laid on the floor next to the chair where it had landed after Grissom had removed and thrown them.

"Shhh" Keri whispered with her finger in front of her mouth. She fingered her sister to follow her back to their room. Once back in their room, Keri turned to face her sister.

"Ya know, I saw Santa kissing mommy earlier tonight. I thought I was just seeing things but I bet it was real now. I bet he's trying to steal mommy away from daddy. I bet he tried to beat her up after she refused to go with him but then daddy showed up and saved the daddy."

"What are we gonna do if he comes back? What if we see him in the city?" Gina asked.

Keri thought long and hard.

"Fat man's gotta go down."

TBC...
