Growth Spurt Part 1

I'm 23 years old this year. Since birth, I've been entrusted by my parents to take care of my 18-year-old younger brother, Kai. However, things didn't always remain that way, especially when his height started to eclipse mine.

Most of the time, it's him that's taking care of me. That started roughly when he was 9, being roughly the same height as I was at 14! I protested it at first, complaining to my parents about how unfair it was for him to be bossing me around. But there wasn't much they could do other than to remind him that I was the older sibling. Fast forward to now, he's slightly more mature and acknowledges that fact, though he still teases me sometimes for being the 'smaller older brother'. I often sigh at that fact but at least he had some respect for me.

Our rooms were on the 2nd level of the house. Recently, I've had to prepare breakfast for him as our parents are away on a work trip. He lumbers down the stairs, heading over to the dining table to have his breakfast. Passing him the plate of food, I can't help but feel small against him. At my current height of a measly 5'4, he's a foot taller than me at 6'4, and he's already 18. He still has a few years of growth ahead of him, compared to mine whose fate is sealed already. I'd hear of stories from friends giving their old clothes to their younger siblings to wear. It was the opposite for me. Everything, even down to my shoes, were hand-me-downs from him. Speaking of, the only shoes from him that'd fit were the ones from when he was 10 years old! A tinge of envy shoots through my mind looking at him as his large feet slap the ground. He had massive size 15 feet, while mine were a mere size 6. His feet being 13 inches long while mine were shy of 9 and a half inches.

After finishing our meals, he headed off for a run while I stayed to do the laundry. Sometimes, I'd take his clothes to wear. His shirt was so baggy for me, and his pant legs would be bunched up on the floor. I couldn't keep them on without a belt! His socks were also so big that they went quite high up my shin! There was just something about wearing his oversized clothes, my cock would grow erect, though it didn't show on his pants, further accentuating his huge size. Even with just his underwear on, my fully erected cock did not stretch the elastics. God was he big.

Quickly hanging up the rest of the laundry, I went to the nearest shop to grab lunch for Kai before he came back from his run.

Upon returning, I noticed that he was already back seated on the couch. I noticed him rubbing his large soles which were facing me.

"Hey bro, thanks for grabbing lunch!" I quickly averted my eyes from his large feet as my cock started to stir. Prepping up the table for lunch, I set the table mat and called Kai over for lunch. Seated at the table, however, I noticed that his sleeves looked slightly shorter, as well as tighter. Upon closer inspection, I realize his shirt is shorter as well. Curious, I asked him.

"Yo Kai, you feeling alright? Your clothes look smaller on you."

"Oh yeah, I was about to ask you that. Did you set the laundry on the wrong settings, they felt tight throughout my run."

"Nope, same as ever." Strange. They did indeed shrink, but why? I brushed it off as nothing, eating another chicken nugget. Finishing off the rest of it, we both cleared the table and that was when I noticed I was now shoulder height to him. Previously, my eyes were level with his shoulders. Now, it was with his lower pec! Was it so in the morning? I couldn't tell as I was focused on making breakfast.

"Did you... Grow slightly? I'm not normally this short to you." I asked, puzzled.

"What are you talking ab—"
"Now that you mention it... That explains why my clothes and shoes felt so tight just now!"
"Guess my puberty growth spurt still hasn't ended yet!" he said triumphantly as he patted his large hands on my head, easily covering it.

I smacked his hand away as usual. He'd always like to do this for fun, much to my annoyance, as it reminded me of how he has severely outgrown my small self. Despite this, I was still interested in how much he had grown and wanted to measure him.
