The second day approached in December and while the first day wasn't much for Jeff, he knew there was progress going on with his body. When the morning arrived, he bolted out of his bed to check on himself again to see what has changed. Removing his clothes to see himself in his boxers, he could see that there were some subtle, yet noticeable changes.
For one, he started to realized that every few hours, he was steadily aging to get the the age Santa would be in. Already, he could see that he has become nineteen and would be entering college by now. He could see that he gained what he could believe to be his final growth spurt as he sprouted to over five feet. His muscles were starting to show proudly with his biceps and glutes having a young college boy build while his chest started to stood out proudly with his chest hair was steadily spreading on it. Even his stomach was starting to show a light dusting of abs. His face was loosing what's left of his childish look and was starting to gain a chiseled look and his hair looked a little messy as it was looking a tad curly. Though he did got caught by something else. While his upper lip has more hair on it, his chin was starting to show little hairs pocking out of the skin. Again, he thought of removing it, but he knew that Santa would look wrong if clean shaven.
Jeff was amazed at the results and soon posed a little bit. "Damn... Check me out. I'm starting to look like a stud." he said in a voice that was deeper in a baritone voice. He soon started to flex a little bit to show off his college like muscles. He soon gave off a bit of a sigh and said, "It's a shame this could be short lived as Santa is more of a hefty DILF then a muscled man. But I will cherish it for as long as I have it."
Knowing he has a day to look forward to, he went to the bathroom to take a quick shower and put on some new clothes. They were a little tight at first due to his growing body, but at least he doesn't have to worry about any rippage yet. Once he was done dressing up, he headed to the kitchen for breakfast and notice that his family didn't notice a thing, not even the fact that his a young college boy then a teenage high schooler. Nor the fact that eating more then normal.
As for his day, since it was Saturday and there was no school for that day. But it was going to be a busy weekend as his family is planning to start decorating the house, starting with the tree. So the mother and daughter went to the basement to get the tree ornaments while the father and two sons went to get the tree. It's basically a traditional thing with the Kendrick's. While getting the tree, Jeff was surprised at how strong he was. Once they bought the perfect tree, both he and his brother lifted the tree to take it to the car. Normally, he could have trouble carrying it with him. But now, he has no trouble carrying it with as he was equally strong as his older brother. It is something he enjoyed the most.
Once they head to the back home, the long day of decorating the tree and making it look perfect. Sometimes, they took a bit of a lunch break before getting back in fixing the tree. While Jeff was enjoying it, all he was thinking about is what other changes were happening to him. Once the tree was done, they were proud of the work that the family had done. They soon had dinner to celebrate the first part of the Christmas decorating. As they were enjoying it, Jeff's dad gave Jeff a beer as he was asked why he gave him it. His answer was simple.
"You're 21 Jeff. That means that you can drink legally. Thought you knew."
Jeff was shocked after hearing that. Has he aged two years during tree decorating? He need to know.
Soon after dinner, he hurried to his room and took off his clothes again to see what altered. What he saw shocked him. Looking at himself, he could tell that he aged two years after decorating the tree and he looked like he was at his prime in college. Another growth spurt happened, pulling him up to around six feet and was looking like a hunk. His muscles were bulging on his arms and legs as his shoulders were broader to show off his manly chest with more hair covering it and were curling around. His six pack abs were starting to show and could see a treasure trail growing upwards above his privates. His face was completely different as he has a chiseled jawline and more hair growing on his upper lip and chin, creating a short mustache and goatee combo.
Jeff was in awe at the sight of his older, muscular self. "Holy shit... Look at me. I am so fucking stacked! I never imagined that the Chronivac would make me this hot." He soon did a few quick posses and there was a slight difference between what he looked like in the morning and what he saw in the evening. "A shame that I will loose this in the coming days of December. I just wish Santa was a fat jolly man." he rebutted. "I almost felt turned on by this."
The moment he said that, he could feel another stiffy coming on and notice his tend was getting longer. Looking down, Jeff realized that his body wasn't the only one that's growing, but his willie as well. Pulling his boxers down, he was surprised to see that his dick was not only longer, but meatier with his balls looking inflated and his pubic hair was starting to get bushy. Seeing that, he couldn't believe what he saw and said, "Damn... That's one big sausage. Guess there is a side effect with the Chronivac. My little buddy doesn't look little anymore. Wonder how functional it would be."
Immediately, he hurried back to his bed and took out his statch of private magazine. Going to Playboy with a naked woman, he pumped his growing rod, imagining fucking the woman on the magazine. Normally, it would take him five minutes to unleash his load. But with the new shaft, it was done half the time. Immediately relieved, he laid on the floor and was in orgasmic bliss. "Wow... That was one quick release. I wonder with Santa banged while he's not at work..." Jeff thought as he envisioned Santa making out with Ms. Clause.
Quickly, he brushed that aside and put on his pajamas, which were too tight for him, and went to bed. He was having trouble sleeping, as he wondered what the next day would bring went transitioning to the man in red. But he knows that once the 25th comes, it would be worth it.
