Christmas Eve!

Light hit Mark's face as it came through the window and woke him up. Rolling over and try to fall back asleep, Mark could only grumble as it proved futile. Sighing, he opened his eyes and looked at the clock beside his bed. It read 10:34 AM and it was then that Mark realized it was Christmas Eve. It had been 4 days since his mom had come home and the family had been enjoying spending time together. However, the happy thoughts were quickly replaced with a bittersweet one when Mark also came to the realization that today was the last day before his sister's deadline. He had mentally given his sister a week to beg for him to fuck her and if she didn't meant the deadline he would approach her about it. Mark had been worried since last Thursday because his sister's previously seducing attitude towards him had been replaced by a normal sisterly one. He was having doubts about whether his sister would approach him and was unsure whether he could talk to her about it without ruining their relationship.

Pushing those thoughts to the back of his mind, Mark rolled out of bed and got dressed before heading downstairs. His mom and sister were already up and in the kitchen. As the family ate breakfast, Molly told her kids that her company was having a Christmas Eve party that night and asked if either of them wanted to come. Both of them gone last year, and with Ashley not being old enough to drink and Mark being one his age, both siblings hadn't enjoyed the party at all. The two politely declined, instead opting to spend the night at home.

The two were kids were decorating the Christmas tree the family had gotten the previous day, when Molly came down the stairs. Mark's eyes bugged out of his head when he saw what his mom was wearing to the Christmas party. Complimenting her ginger red hair, Molly wore a tight red dress that came down a few inches above her knees. The chest wasn't overly low-cut but just barely showed a little bit of cleavage. The thin straps showed off her pale skin, freckle covered shoulders. (https://i.pixxx.co/bKWn4BL.jpg)

Embarrassed by the return of his growing cock, Mark quickly put the tree between himself and his mother and sister. Spinning around to show off her bodacious ass, she smiled and turned to her kids.

"So, what do you think?" she asked.

"Wow, mom! You look hot!" Ashley replied enthusiastically.

Molly blushed and thanked her daughter for the kind words. Turning to her son she asked, "What about you, sweetie? What do you think?"

Peaking out from behind the Christmas tree, Mark's face was flushed which Ashley noticed but only smiled and kept her mouth shut. "You look great, mom." Mark said with a dry throat. He quickly turned back to decorating the tree and urging his cock to deflate.

The kids had finished decorating and Molly was waiting for her ride. The company party was being held at a hotel in a larger city 2 hours away. Rather than drive herself, Molly was carpooling with a few of her coworkers and were planning on spending the night at the hotel. Ever since his mom had come down in her dress Mark's lust had been building steadily and was reaching the point of boiling over. He had tried jerking off but his cock stayed perpetually hard. He had tried locking himself in his bedroom but he couldn't get the thought of tearing the dress off his mom and fucking her relentlessly out of his head. If he didn't do anything to relieve the lust soon, Mark felt he was going to go insane.
