Regardless of how old I looked like, I was still the scrawny 16 year old. So, I attempted to put on the largest pair of boxers I had.
As I tried them on, my body started to feel like it was shrinking. I was covered in some tingly feeling. Paying no mind to it, I just went ahead and feel asleep.
Waking up to my alarm, I got up and expected the big body I had yesterday. To my surprise, I was back to normal.
I thought it was all a dream, so I checked the date. “Sunday”, is what I saw on my phone. I went downstairs and saw that everything I had done was still there.
It had do be some kind of dream, people don’t age and deage overnight.
I shook it off and performed my normal routine again. This time, I wore my own boxers, and went to work.
Later in the day, I couldn’t get the idea that it wasn’t a dream out of my head. So, when I got home, I experimented.
I rummaged through all of my dad’s underwear, and laid them in a line on my bed. Then I laid some of mine on my bed.
I took off all of my clothes, set up a camera to record, and put on a pair of my dad’s underwear. I sat on the floor and started playing video games. As I sat there, the camera I set up recorded me. The second I notice my body is back to the bigger me, I’ll load the video and watch it.
After an hour or two, my body started to feel different again. I looked at myself, and I was growing patches of hair on my body. It wasn’t like yesterday, but it was a growing version. I continued to my game, until it was time for bed.
Around 9, by body was even older, but not as old as yesterday. I actually was starting to gain fat on my body.
I turned off the camera, changed my underwear to my boxers, and looked at the video.
It wasn’t a perfect test, but I was able to see the progress the underwear did on my body. I kept the video, cleared off my bed, and went to sleep.
Waking up, I decided to experiment some more. This time, I was going to wear more than underwear. I went to my dad’s room and grabbed some of his clothes. I tried on some of his underwear again, but added some pants and a shirt and recorded my progress.
Almost immediately I felt growth. Not even half an hour later and I realized I was back to the dad body I had on Saturday. I turned off the camera and watched the video. You can see the progress go way faster.
I took off his clothes and put mine back on, but I wore a full outfit. Shirts, pants, socks and shoes, and boxers. The transformation felt faster, and I was back to my old self again.
I wasn’t sure what to do with this information, other than use it if I wanted to transform faster. The more clothes of someone’s age I had on, the faster it went. So it means the big body I had was me when I’m 38.
A lightbulb appeared in my brain. “If dad’s clothes made me older, then...”
