It is the start of December as the Chronivac's affects have already started to take effect. Jeff had little trouble sleeping as he wondered how much would change when he wakes up. by the time the morning came and the the alarm was blaring, Jeff immediately bolted up from his bed and hurried to the mirror to see what has changed. Removing his under shirt and pajama pants, he looked to see what has changed. So far, it didn't look like much has changed. He still have that teen body with a minimal build on his body and a round face and some messy brown hair. However taking a closer look, he noticed that a few hairs were starting to poke out of his upper lip. Typical, it is basic teen stuff, something in his mind told him not the shave. Preferably because Santa always has a beard and never shaves it.
All and all, nothing different from him. Jeff believed that it it was just the start of December, so the interesting changes won't kick up until later in the month. Brushing that aside, he left for the bathroom, took a quick shower, and dressed up to go to school.
At breakfast, he was with his family as they were discussing what are the plans for today or tomorrow. Jeff's mom then came up with the idea on decorating the house for Christmas. Jeff, of course, agreed to it as he wanted to help his mom with that, though he was more joyous about that then before. Maybe the Santa changes were kicking in, but he doesn't know it yet. Once breakfast is done, Jeff and his little sister took the bus to their school has mulitple departments from preschool to high school.
As school, Jeff was going through his usual day with him. Going through classes, the gym, even are activities. During lunch though, he felt a little bit of wooziness as vertigo was setting in. Feeling off, he left the cafeteria and hurried to the bathroom. Looking to the mirror, he noticed that he looked a little taller then before, by a few inches maybe. He might be looking a little older as well he could be seventeen instead of sixteen. Looking closer to the mirror, while his face is still the same, he could see the more hair poking out of his upper lip, some growing longer then the others. He didn't think it would grow that fast, but if the program is causing it, he could get use to it. After all, he might look good with a mustache, even a beard when we becomes Santa. Seeing the slow and steady progress, he walked out of the bathroom and moved on with his school life.
Once school was over, he picked up his sister and they both took the bus back and returned home, doing his homework early and having dinner with his family. The strangest part is that none of the family members or his friends didn't notice the minor changes. Preferably because reality was altered to to see Jeff the same to them while he changes into Santa. Another strange thing is that he was eating more food then expected. He already got a second helping as his apatite seems to be changing. Maybe is because Santa eats more food then a normal human. Could explain the constant milk and cookies he consumes whenever he goes from house to house delivering gift. Another thing Jeff needs to get use to.
After dinner, Jeff hurried to the room and locked the door just so he could get his privacy. Immediately removing his clothes, he could see that there were some changes in his body, a little bit, but was still changing. You could see you have grown another year and are now 18, just a full fledged adult. He could see that he grown another couple of inches as he could see muscles starting to show on his body. No fat yet, but it would soon change in the coming days. He could even see some chest hair beginning to grow as a small bit of dusting appeared. Even his face was changing with more hairs sprouting on his upper lip, making it a teen like stache.
He looked at himself and was impressed by it. "Wow... Look at me. I looked like a late teen now, almost college bound too. If this proves that I'm becoming Santa, I don't know what will."
Looking to himself, he felt turned on with his changing body. So much so that he felt something stirring in his boxers. Looking down, he could see something tenting up in the front, knowing what it means. "Well... Someone seems happy. All right, little guy, you want some fun, I'll give it to you."
He soon walked to the bed and pulled something out under the bed. What it was is a collection of Playboy and swimsuit magazines meant for honry teens. It's a known fact that Jeff always masterbates on certain nights and always have his stash with in his relieve some tension. Course, his family doesn't know it as he sneaks them in his backpack. And while he has his girlfriend, he always have to practice when they were getting intimate.
So after getting his magazines out, he took one out and went on the bed, pulling his boxers down to show off his stiff dick. Opening the magazine, he found a good model that looks hot and place his hand on his shaft, strocking it up and down while picture himself making love with the model. It only took a good five minutes before he ejaculated and left a bit of a mess. One Jeff relaxed, he cleaned himself up and put his pajamas on, going through with a few things before going to bed.
And so the night is over as Jeff went to bed. As far as he is concerned, the changes were slowly starting, but not to show that he's becoming Santa. Thankfully, it's the 1st of December and it's a long way to the 25th. Who knows what the remaining days will be like.
