Mary nervously sat there, her fingers still slightly shaking as she once again read the note. It had been handwritten on the joke inside her Christmas party cracker. It simply read, “Flash the boss your panties,” and it was signed, Sir.

She recognised the writing as belonging to her husband, whom she normally called Kris. This was part of their ongoing festive sexual dare game, one they had agreed to play to spice up their sex life over the busy Christmas period.

However, there was one thing that perhaps her husband had not thought of, and that was she was currently pantyless, having earlier taken them off to surprise him.

But this was a dare, and Mary was not going to lose this game to her husband.

She gulped her wine and gazed at the boss, a tall, portly man dressed in his festive suit. Taking a deep breath, she scanned around the partying room, where everyone seemed to be dressed as Santa’s little helpers, and the light came from ten thousand fairy lights. 

With trepidation, Mary slowly eased her legs apart, her eyes locked on the boss. She had never done anything like this before, but she knew her husband wanted this too. It was just another dare, another part of their festive sex game.

As her legs slowly spread apart, nerves ran through Mary's core, her little red Santa dress rising ever higher. The cool air that now teased her pussy did little to douse its molten heat.

Would he look her way? She thought, giving herself three seconds.

On tenterhooks, she counted, “One, two… two and a half, three.”

With a knowing grin, the boss’s head glanced in her direction, and his eyes quickly locked on her open, wet pussy.

Mary dropped her head, embarrassed that she had done such a wanton act, her legs instantly closing now that her dare was complete. But then, in an instant, he was there, towering above her.

She looked up and realised that his eyes were already undressing the rest of her.

“I am Nick,” he announced.

Mary, almost in a trance and lacking belief, smiled at him, her body already craving this powerful man.

“Dance,” it wasn’t a question.

He took Mary’s hand and guided her to the throng of Christmas party revellers.

As they danced, Mary soon felt Nick's hands taking liberties, checking her bottom and pulling her close, particularly when Nat King Cole's "The Christmas Song" filled the air and Nick's hard cock pressed into her.

“I want you,” Nick remarked, knowing they had chemistry together. He then whispered, “Reach into my top pocket,” his hand creeping once again under her short red dress.

She did as requested, finding another note in a small red envelope, which read, “You are to do as Nick demands.” Once again it was signed, Sir.

Mary giggled to herself; she felt relieved and then showed the note to Nick.

With a smile, he promptly took Mary’s hand and led her out into the foyer where a large, well-lit Christmas tree stood. The pile of wrapped presents around its base stirred up thoughts of her husband and that tomorrow was going to be a busy day.

As the outside door opened, the waft of cold air reminded Mary of her knickerless state and prompted her to state, “Nick, there’s a nice, warm, cosy room upstairs.”

“You need to follow Sir's instruction,” Nick remarked as he led Mary through the snow to his waiting transport. “I will put the heating on, and you will soon warm up.”

As she climbed into the back, Mary could feel nine sets of eyes watching her. It felt like she was performing the walk of shame before she had even committed the sexual act. It was a wicked thought that made her feel both naughty and guilty.

Nick gave an instruction, and slowly the autonomous vehicle pulled away; as it did so, a surge of heat radiated onto the couple. 

“Aren’t you worried about it crashing?” Mary remarked as she snuggled up to Nick, his fingers already under her skirt probing her wetness.

“It’s never happened—yet,” he remarked as he pressed his mouth against hers. Their passionate kiss continued, and small moans of pleasure escaped into the night air as his digits continued to dip into her folds.

Mary wanted this commanding man, and his pants were soon discarded. She then took his cock into her mouth, her tongue swirling away before she started to bob her head up and down.

Then, in a swift movement, Mary removed the rest of her clothes and straddled Nick’s lap, his thick, hard cock erect and ready, pre-cum oozing from its tip.

Her wet cunt needed its emptiness filled.

With a groan, Mary sank onto the hardness of Nick’s cock, it penetrating her wanton, needy core. She needed this fuck; it might not have been on the dare list, but she had come this far.

“That's right, fuck me, you slut,” Nick teased.

Lustful moans filled the air as Mary’s body rode his long, fat cock. Nick's hands rested on her two large breasts, gently rolling her nipples.

“Fuck,” Mary cried as she felt Nick’s cock pulsing inside her.

Gazing into each other's eyes, their closeness was evident. They both knew they had a long day of work tomorrow. That this fuck would be the last until after Christmas Eve, the party below a celebration of getting the year’s work done. 

Nick grunted, his erection buried deep inside Mary, and with a primaeval groan, his cock erupted into Mary Christmas, his wife. It triggered her orgasm as she came loudly on Saint Nicholas’s dick.

With her husband’s cock still inside her, and the sleigh flying through the night sky, Mrs. Claus warmly remarked to her loving husband, Santa Claus, “Merry Christmas, darling.”
