Gabriel wakes from his sleep, not that he was able to sleep anyway since it is Christmas Eve. He throws off the covers and throws his feet over the side of the bed. Slowly he creeps to the door and opens it a crack to peer down the hall. The light from the living room is the only one on that he sees. Tonight is the night Santa was coming and he hoped to get a peek at him.
He pushes the door open a little more, taking his time as to not make any noise. Then he slips out into the hallway and toward the stairs. At the top he peers down and sees a figure already sitting there halfway down. He already knows who it is; his twin sister. Jenny.
They were home for Christmas Break from college and like every year they crept down stairs to see their mother fucking Santa. He creeps down the stairs catching the attention of his sister. She puts a finger to her lips and he settles down next to her.
"Look," she whispers. "It's actually him."
Gabriel looks through the slits of the hand rail to see their mother sucking on Santa's cock, with her full breasts hanging down beneath her, swaying in time to her motions. Santa's face is contorted in pleasure and his hands are grabbing at the couch cushions.
Santa then sits up slightly and rolls their mother over onto her back. He moves down her and peels off her lacy panties and then buries his face deep in her pussy. A soft moaning sound escapes their mother's mouth as Santa licks her pussy.
Gabriel glances over at his sister. He can see that this erotic scene is having an effect on her. She is squirming in her nightshirt and her breathing sounds a little uneven. Her entire focus is on the sights in the living room and she is lost to what is going on around her.
Gabriel moves behind her and rests his hands on her hips. He then moves his hands up and down her side slowly. After a few passes, he slips them under the hem of her shirt and is running them up and down her bare torso and then up to cup her very round and firm breasts. They feel quite soft under his hands, with small nipples on the tip that are rock hard.
Jenny leans back slightly against Gabriel's body, never taking her eyes off the action in the living room and allows his hands to roam all over her full breasts. Sensing this capitulation, Gabriel sends one of his hands down lower. He finds that her cotton panties are already soaked with her juices and when his finger touches the outside of her pussy, Jenny gasps in pleasure.
