“As a plastic surgeon, I’m always tickled by the look clients give me when I tell them I’m all natural. Nobody believes me but I swear it’s true! Hell, a lot of the guys I work on ask for a BBL as big as my bum, but they’ll never be as large as me. I’ve got a pair of glutes that can’t be recreated!”

[ANIMATION!] Haze loves to tend to his exotic species of plants and fauna in the Greenhouse, even if he was a bit clumsy with them at times. Turns out provoking strange glowing mushrooms can elicit an unexpected spore cloud to render the agitator incapacitated...by making them grow massive.

When you get to Herc's size, you're gonna need an attendant at the bath house. Someone to reach the hard to get to places cos your muscles are so big they get in the way. Someone to scrub the deep chasm between your massive pecs...
Hercules waddled along through the bath house, immense balls dragging behind him, using his powerful thighs to push his fat cock forward too. He struggled to see past his jiggling pecs, in search for an attendant. He was relieved to see a little guy carrying a bucket and called him over.
"Ah, so you'll be helping me bath today?" he asked hopefully. The guy stared in shock, eyes roving over Herc's godly body. He nodded. "Sweet, my mobility's really gone down since my last growth spurt."
Despite himself, Herc felt a throb of pleasure go through his cock. Having all this muscles could be a pain sometimes, but it felt so good when he grew. Not to mention, just the sheer weight of his mass, the power he felt with even the slightest movement... Even if it did mean he struggled to reach certain places...
"Not to mention, you know, having my dick drag on the floor all the time..." he said aloud. He sighed, setting his pecs jiggling once more. Gods they were feeling full.
"Uh..." he continued, "I could really do with a milking too. I'll even let you drink some too."
The bath attendant held his bucket protectively over his crotch, hoping to his his boner. Not that his twig could match to the mammoth TREE before him! He couldn't believe his luck though, to get to help was this...this god!

There's trouble in the mines and without the town's usual wizard to help protect them, apprentice mage Seb calls on the new sorcerer to help out. His idea of helping involved giving Alex the fighter a little...boost #StarGrew
There's danger in the air as the mines near town are acting up. Usually it would be up to the local wizard Rasmodius to keep them under control, but since he's gone missing, it's up to the villagers to help themselves.
Local Necromantic Wizard Sebastian calls on the town's newest resident, a Sorcerer by the name of Greg. While he's trying to enlist the sorcerer's help, Greg seems to be more distracted by one of the locals practicing his sword forms. Shirtless. 
All this talk of strengthening wards doesn't sound productive to Greg, and after seeing such a strong fighter in motion, he decides to use his magical speciality to provide a more...hands on approach.Alex is surprised to find himself blowing up like a muscle balloon! He drops his sword in surprise as he hefts his new massive set of pecs, but his body is still growing bigger! Soon the straw dummy he'd been sparring against is swept away by his enormous cock, which proceeds to bash through his training grounds too!
Greg pats himself on the back, thinking the town saved now they have such a behemoth to protect them. Until Seb points the giant guardian is too big to move and is no where near the mines!

What happened to that boy?! You swear, just last year, he was a sweet little twink. Harmless. But you can hardly recognize this MASSIVE HULKING BRUTE standing in front of you now!! This can't be real... but it sure feels real... #musclemorph 📈 @juicedcatboy.bsky.social
Looking back at old pictures, you still can't believe this is the same guy. He used to be a sweet young boy. Skinny, but sweet.

Now look at him... He TOWERS over you with his HULKING frame! His pecs are bigger than his head! His arms are as thick as your torso!! He was a GIGANTIC, muscled freak of nature!!

He did confess to you, he's still not done... He's hungry to grow even more and then MORE!! He was UNSTOPPABLE!! How big was he gonna get?!
