"Holy fuck, I'm huge!!" the bodybuilder was in awe of the now tiny warehouse, he was given a test growth serum. Fellow giant and test subject Charlie looks up at him, much taller and stronger. "He's way bigger than me, this is gonna be fun." He chuckled.

Daddy called for his boy to come and look out the window beside him. The city buildings towering up and out of their view. Daddy put his arm around his boy's shoulders and commanded him to touch his thick muscles.

The boy obeyed, feeling how strong his Daddy is. Groping and massaging until his Daddy raised his hand. The ring on his finger started to glow.

"Don't stop, my boy. Surrender yourself to Daddy... and make me GROW!"

The boy obeyed, feeling his briefs loosen and drop as he shrunk! All his size getting absorbed into his Daddy who was stretching taller and taller above him!!

Two days have passed and Daddy has drained so many boys of all their size in that time. It only took three twinks for Daddy to grow too big for his puny apartment!

The 18ft Daddy marched out, dressed only in a California King bedsheet, down to the warehouse gym on the corner. There he found more boys in awe of the gigantic muscles on his towering frame. Bigger boys... More to absorb...

As Daddy grew bigger and bigger, so did the crowds! He stretched 5-stories, 10-STORIES TALL! The crowds groveling at his feet just to make Daddy even bigger!

As Daddy reached the up PAST the height of all these skyscrapers, he knew he was UNSTOPPABLE!! Nothing was gonna stop him from continuing to grow and GROW and GROOOOW!!!

"Come to daddy, boy. Look up at that tower. Now touch daddy's muscles... Imagine me growing up like a skyscraper!"

*grow* *GROOW*

"MMFF- that's it, my boy! Surrender your size to daddy!

β€”March 1stβ€”

I woke up to my morning wood spilling out of my boxers. My dick was so big and hard, I couldn't wrap my fingers around it, but it felt so good to try... My swollen tip was glossy with thick precum as I massaged my shaft.

And then my cock flexed itself bigger... That's when I realized what day it was. The first day of Macro March...

My growing dick was just the beginning. Soon, the rest of my body would start to grow as well. I only had a few hours to get prepared and get out to somewhere with enough room for me to grow!

β€”March 4thβ€”

My growth has been non-stop for the past four days. Every inch of me bulging and stretching as I grow bigger and BIGGER!!

I outgrew my apartment by noon on the first. And outgrew my buddy's warehouse by sundown on the second. My massive growing limbs and exposed cock refusing to stay cramped in any space!

Today, my growth spurts have been more relentless than ever! In one single spurt this morning, I stretched 10 FEET taller! My bulky shoulders pushing against the sides of skyscrapers! I was a MASSIVE FREAK of nature tiptoeing through downtown. But the cold steel does feel great to rub my colossal dick against...

And it was only March 4th... Soon this city will dissappear under my foot, and I'll still have more to grow!!

Matt found he was much more massive than he was when he went to bed last night. All of a sudden his body began to pulse bigger and bigger - and it was then that Matt realized it was the start of Macro March. And his growth is just starting!

This influencer started off filming a simple thirst trap of an ab cramp, but little did he know what it was really doing to him. By time he noticed, he craved more...now he posted his growth and watched the post blow up. But now he can barely move from filling his kitchen up...

Chatting last night with @caseystudy.bsky.social about progress and how insane it can look when you see a picture from 11 years ago, before I ever touched a weight (and he has an insanely dramatic blow up himself). 2015 I was a very different person in general, physically and mentally.

Weaponizing a mutant surely is a bad idea, specially if you dont take enough caution in the process

His growth went out of control , the nearby city is in trouble, they need heroes to save the day
