Jeff liked how he looked and had exactly what he wanted though, there was no smooth transition from hairless teen to being more than the average man in face/body hair. It dawned on Jeff that he'd either need to undo it, regularly shave every visible part of his body daily till he's 17 or 18, or he needs to make everyone think he has been hairy all along by using the reality change option.
Jeff scoffed... Part of his excitement was being able to show off his newly acquired facial hair to his friends, but a bigger part of him was excited to be recognized as no longer being a boy in general, at a glance. Meaning not undoing it, and not shaving it every day which he knew he wouldn't be able to keep up with. Reality change it is. Jeff put his dad's shaver back, in a minute, it would mold itself into whatever a hairy Jeff would have molded it into anyway, all he needed to do was get back to the chronivac.
"Jeff! I heard a weird noise inside the house!" Lisa called referring to the shaver buzzing from her parents room when her parents aren't home... It was a miracle she noticed considering that her music was blaring...
"She's better than a fucking guard dog." Jeff muttered under his breath, in frustration... Half truths work best. "You caught me, I was playing with dad's shaver... I'm going to need one someday and wanted to know what brand he trusted." It was plausible...
A moment later he heard the door slam feeling her eyeroll. She was disinterested, excellent, and a close call. Jeff made his way back to his room and the Chronivac greeted him just as he'd left it, except for a pop up saying that the prior transformation was completed. He was given the option to dismiss the popup or modify it... He chose modify and selected the option to alter reality. He opted to accept, and a few seconds later, he felt a wave pass through.
Returning to the main bathroom and searching the drawers, he found a shaver similar to his dad's that he knew wasn't there a moment ago. Flipping through his phone he saw his selfies, all accented with various styles, even colors, of facial hair. It seemed like his body hair started taking off around 10 or 11 and by freshmen year he was shaving daily, he recalled being excited about going into high school for the simple fact that he wouldn't look so out of place having facial hair... unlike being the only one in middle school with beard shadow.
Jeff's facial hair was styled. trimmed sideburns connecting to a chinstrap, merging into a trimmed goatee/moustache. It wasn't his original goal but between 12 and 14 short sideburns were all he was allowed to keep, so he (alternate Jeff) had sated his sideburn desire and now was desperate to try other styles. It was also dyed turquoise which seemed off, but he understood that when he's older he might not have the freedom to experiment...
Jeff took the rest of the day as it came, the reality change seemed to extend beyond the Chronivac's 20 foot radius and neighbor's didn't seem to question who he was. Dinner was normal, though Jeff was both used to, and enamored with the sensation of eating with facial hair. He could feel it on his mouth, every time he opened to take a bite, every time he chewed... it was there, but seemed normal, all together it was odd...
The next day at school Jeff noticed he was slightly more recognized by people, but the day was less out of the ordinary than he'd hoped. He drove home, worked on his homework, and went about his normal 16 year old life.
