Bending Brothers Get Big! (Mako and Bolin) + short story! (Patreon)

Mako and Bolin had always been an athletic pair of brothers, but never took working out overly-serious. But after losing pro-bending match after match, Bolin decided to finally start working on his body. With a stronger body- he'd be more agile and quick on the filed! His body saw results fast, especially in his arms! He even tore off his sleeves just to be more comfortable with his extra bulky arms! He ran to show off to his older brother trying to convince him to work out with him! Mako was unsure at first but Bolins constant flexing had convinced him to join his younger brother.

For the next couple of months, the brothers spent all their free time lifting and working out. Bolin focused less on agility and more on size and power! Mako kept his training quite simple, at least compared to Bolin. Bolin was hitting new PRs nearly every day! Along with eating the whole kitchen he put on a TON of muscle on fast! The younger brother seemed to be catching up to his older brother in height too... and fast! Who knows why they were getting taller too?! Mako was much more toned than his younger brother. His broad shoulders got broader and his pecs had become a nice shelf on his chest. Their undershirts were stretched across their growing bodies as the two boys lifted more and more.

The following months the brothers saw some huge changes in their physiques! Mako had put on a ton of muscle onto his frame, along with growing slightly taller! His pecs had made it quite hard to pull his undershirt over... Bolin on the other hand had become a GIANT! The younger brother had gained over 150 pounds and 9 inches in height! He had surpassed his older brother in nearly every aspect! His pecs and abs had grown so big and blocky it was starting to get hard to move around gracefully. Even the boys voices were getting deeper, their grunts sounded like guttural growls. It would be a disservice to not mention their growing manhoods... The brothers had never been small down there, but recently it seems they've been supersized down there too! Their boxers can barely combat their meat now! Bolin had become especially huge down there, not only longer but extremely thick! it became quite the nuisance when working out- whether his balls slipped out or having to deal with a boner mid-workout. The pair had become a bit too comfortable around eachother- relieving themselves around eachother whenever they had to.

The day of the final Pro-Bending tourney was nearly upon them. With the help of some special supplements, used by Bolin, Mako was able to explode in size just like his younger brother. His unreasonable mass had surprised everyone around him. Practically being a giant at his new size. His abs popped out of his torso and his arms were pushed out by his monstrous lats. Below was his enormous manhood. The supplements had helped it grow to an obscene size, now Mako learned the previous struggle of is brother. Speaking of which- Bolin had become a BEAST! The younger bro was constantly eating or lifting, helping his grow to an astounding 8'7. He was barely able to fit in their room without hunching over- even then his traps and back would still crash into the ceiling! His gut had hidden his monstrous abs, but his other muscles bulged obscenely every where else. His monster manhood had destroyed many toilets too... perhaps he was getting too big for his own good. The two boys living together had become a struggle, especially with food! Despite becoming quite famous in the pro-bending fanbase, they still struggled to get enough food to fill up- but the two always found a way. even if it involved violence or stealing...

The Final Pro-bending Tourney of the season was finally here! The boys had armed up their doses and amped up their training to 100! in just a couple of weeks the boys grew nearly over 2 feet taller! They can't even weigh themselves anymore! They were more pumped than ever. It was almost scary... Their stomps crushed the floor beneath them as they made their way to the ring. Their opponents shivered in freight as they started up and up... and up at the ginormous seething, bulging boys. Matches ended just as fast as they started with these two. Despite looking effortless, they boys were still dripping in sweat- although at their size they were always sweating. Their monstrous manhoods were barely contained by there custom-made speedos, falling out and flashing the audience and opponents a multitude of times.  Even up until the finale they pummeled their opponents to the trophy! Their deep voices echoed through the stadium, vibrating through each row of seats. Their celebration even shook the stadium a bit. however Bolin's ginormous hands had managed to crush the trophy on accident... The giant boys didn't care they just continued to flex and moved onto the nearest buffet to clear the kitchen!
