Christine lies on her side, eyes open, staring into darkness. She’s pretending to sleep, but she can’t, she’s too excited. Too horny. It’s almost time.

Bill stirs. He leans over and plants a soft kiss on her cheek, whispers “Don’t wake up.” She smirks as she listens to him stomp across the room, open the door and close it again. She gives it a few minutes, then flicks on the light and gets up herself.

She pulls off her pyjamas top first, freeing her big juicy tits, causing them to bounce, then she slips her bottoms down. Nude, she crosses the room, a smile of excitement on her face. She opens a drawer and the lingerie is waiting, a red sheer negligee with white fur trim, matching thong, stockings, and a santa hat. She pulls them on, piece by piece, and takes a moment to admire herself in the mirror.

She slips out the door and makes her way down the stairs, careful not to make a sound, not to wake anyone else up. She reaches the bottom, walks down the hall and peeks around the door.

There he is. Santa Claus is kneeling in the middle of the room, reaching into his sack and carefully arranging presents around the tree. She bites her lip and places a hand on her thigh, and slides it up under her negligee to touch the front of her thong. She smiles, feeling the dampness there already.

“Anything in that sack for me?” Christine asks from her hiding place.

Santa jumps theatrically, then jumps and smirks at her. His tone is at odds with the look on his face as he begins to speak in an artificially deep voice, “Ah, Christine, you frightened me.”

Christine steps out from behind the door and crosses the room, step by step, with a pout on her face, “I’m sorry Santa, I try to be a good girl but you know how hard it is….”

“No, Christine,” Santa says, “There’s nothing for you in my sack. You know you’re on the naughty list, you’re always on the naughty list.”

“Why?”

“You know why. I see everything. You know I saw you cheating on your husband. There was the young man at Debra’s wedding who you snuck up to your hotel room after dinner, he bent you over the bed and fucked you silly.”

“Ben didn’t mind. We have an open marriage, he encouraged me to do that one.”

“There was that time you sucked your married boss's cock and swallowed his big hot load for him in exchange for a promotion.”

“Mmm,” Christine places a hand on Santa’s chest, “I bet Santa jerked his hard cock while he watched that one?”

“There was that girls trip with Sue and Tina, where you pretended you had a headache so you could stay back in the room and get tag teamed by those locals.”

A momentary look of panic crosses Christine's face, “I didn’t know you knew about that one?”

Santa grins widely, happily, “I’m Santa Claus, I know everything. I know you’re on the naughty list, you’re not getting anything from this sack,” he pats the bag full of presents behind him to make the point.

“Oh?” Christine asks, grinning, as she reaches between Santa’s legs and finds his cock. He’s rock hard. She slides her palm down the front of his shaft until she finds his balls, “What about this sack? Is there something in here for me?”

Santa shrugs, a happy smile on his face.

Christine places her hands on his chest and gently pushes him back to sit on the couch. She pulls her negligee up over her head and tosses it on the ground, then grabs her tits in her hands and gives them a gentle squeeze. She straddles him and he takes her tits in his hands and spends a few moments exploring them. He takes one nipple in his mouth and kisses and sucks on it, causing Christine to moan.

“Does Santa like my tits?”

“Santa loves your big naughty tits Christine. Mrs. Claus has nothing on these.”

Christine smirks in satisfaction, then reaches both hands down to undo his trousers. She kneels on the ground, and watches in delight as his cock springs up in front of her face. She bursts out laughing as the tiny fake beard wrapped around the base.

“You think there’s something funny about Santa’s pubes?” he asks.

She moves her hat out of the way so she can catch his eye with a look of mock disapproval, then opens wide and lowers her head. She keeps eye contact with santa as she grips his cock with her lips and slowly slides them up and down the length of his shaft.

“Oh fuck yes, suck Santa’s cock like a naughty slut housewife,” he tells her as he massages the top of her head.

Christine loves having his cock in her mouth. She takes her time, sliding up and down, savouring his taste, his smell. She’s intensely familiar with this cock, if she wants she can make him cum in her mouth in minutes, but that’s not the plan for tonight.

She releases him, stands up and slips her thong off down her legs. She rips the little beard off his cock, then straddles him again. She takes his it in her hand and points it upwards at her opening, “Does Santa want to fuck?”

“Santa really wants to fuck,” he says, as he pulls her into a kiss. His hands explore her ass, tits, back, thighs, as she lowers herself onto him.

“Oh fuck,” she squeals softly, as his cock penetrates her. She grinds her hips back and forth on top of him, grunting and moaning, doing her best to suppress the sounds, the bobble of her hat flying around her head in time with her motion.

“You know fucking Santa is naughty, right?” Santa grunts as he reaches down between their bodies to find her clit. He rubs her frantically as she grinds on his cock, and soon she needs to bite down on the back of her hand as she cums, her body jerking uncontrollably as she struggles to contain herself.

She comes down, breathing hard, and relaxes. They smile at each other, then she starts again, bouncing up and down on Santa’s cock, his pleasure her only concern now.

“Am I a better fuck than Mrs. Claus?”

“Oh yeah, absolutely. Am I a better fuck than Bill?”

“So much better!”

He cums suddenly and she stops bouncing, and relaxes, watching with a smile as he fills her pussy. She kisses him on the cheek, then climbs off him. She pulls her thong back on to not make a mess, then gives Santa a kiss, “See you next year.”

She grabs her negligee and leaves Santa sitting there bottomless in a daze. She quietly makes her way back upstairs, slips her pyjamas back on and settles back into bed.

A while later Bill quietly opens the door.

“Hey baby,” she says softly.

“Oh, sorry, I didn’t want to wake you,” Bill settles into bed next to her and pulls her into his arms.

“That’s ok, I was awake. Where did you go?”

“I, uh, I have to admit I snuck out to fuck a slutty housewife behind her husbands back.”

Christine grins and reaches between his legs to find his soft cock, “It feels like she left you satisfied,” she teases him.

She settles onto her side to sleep, contented, with Bill spooning her.

“I think Santa came,” Bill says.

“I’m pretty sure he did.”
