His boots made a loud thump as he hit the floor after descending the house's chimney. Dressed in his signature red and white outfit, slightly loose on his powerful-yet-chubby body; strong and handsome face, mostly covered by his billowing white beard, looking around the living room.
He checked his list again. Weird. There was only a first name registered for this house. "Corey". No last names, no age, but still classified as "good"... He would need to have a talk with the elves responsible for this year's list, this was a very big overlook on their part.
But regardless of that, the living room seemed decorated enough, 3 socks hanging from the unlit fireplace. A big Christmas tree with some presents already on its base. Oh, there it was: a glass of milk and some cookies on the small center table. Clearly this was a home that celebrated Christmas, so he stopped worrying about the weirdness of the list.
A bit of practiced movement and he easily hauled the heavy sack over his broad shoulders. Opening it up he quickly found a gift for this "Corey" person, a small light box, and expertly put it under the Christmas tree. And now it was time for his spoils.
He took his time eating the cookies. They were honey and oatmeal flavored, kinda rare as far as Christmas offerings go. When he was finished he drank the milk, thinking nothing of the slight tingle that ran up his tongue while drinking it.
Putting the glass down he turned around and... And..? He blinked, what was he about to do, again? He turned his head and his vision seemed to lag a bit, he felt woozy, almost hazy as he looked around open mouthed trying to get his bearings.
What broke him out from his haze slightly was the sudden flood of sensation coming from his skin. He could feel his clothing rubbing his powerful thighs as he paced around the room. He could feel it rubbing his arms as he felt around his body, and his nipples hardening under the stimulation that his shirt was providing.
This couldn't be normal. He thought, as his hands pressed on his baggy clothes, grunting slightly with every new touch. Something was wrong. He registered, as his grunts started sounding more and more like little moans of pleasure as his hands ran across his soft belly, one grasping at a nipple. I need to find out what is happening. It felt so good as he unbuttoned his coat, exposing his meaty pecs covered in snow-white fur. So good. He stuck one hand underneath the fabric to grasp at a nipple, letting out a long moan. It's wrong. His face felt flushed, his eyes closed in pleasure as he bit his lips slightly, his free hand rubbing lower and lower on his belly. The milk. His other hand brushed against it and his knees buckled in pleasure, his hand squeezed and pulled at his dick as pre started to stain his pants. Oh yeah, feels good.
He felt his climax rapidly approaching as he played with himself through his pants. Must resist. His mouth stood open, his eyes fixed forward as he moaned in his self inflicted pleasure. Can't stop. But as he inched closer and closer to orgasm, he started feeling new things...
