I have a confession 👉👈
The text says : "My irl type: Human that will let me hug them". The illustration beneath portrays two cute guys huging romantically. The text next to it says : "My secret type: Human that will let me pump them as big as a bus". The illustration beneath shows one of the two guys blowing up his boyfriend's muscles with the help of an air pump going in his ass, transforming him into an enormous immobile blimp laying on the floor.

While not the Day of Black Sun, there's definitely something putting the Fire Nation in darkness. Iroh has maybe pushed himself too far, pumped himself with too much heat to contain!!

Alex is a VERY powerful juicing machine.

Giftart for Lenn!
A few angles of Alex (a goat, wearing an orange jockstrap with matching sneakers) having anal sex with Lenn (a round blueberry bear with horns) Center: Alex grips Lenn's juice-engorged dick while shoving his face into the bear's balls. He's on his tippy toes, while Lenn is belly up. Lots of "Plap!" and "Slosh" sound effects. Upper Right: Same as center, but alex is gripping Lenn's taint while thrusting. Alex has his tongue out as Lenn's balls rest on hus snout. Upper left: Lenn, whose head has sunken into his overinflated torso, yells "HARDER! Atta boy, THAT'S the STUFF!" Lower right: A worm's eye view of alex's balls bouncing off lenn's butt.

He's finally giving in to the pleasure of the transformation... Only happy thoughts of being a good, ripe blueberry and growing bigger from now on ~💙🫐

#blueberryinflation #inflation
Illustration of a young man turned into a giant blueberry. He's fully spherical, head, hands and feet sunk into his round, taut body, but still growing. He has a very flustered expression, almost crossed eyed in pleasure. He has an erection and is leaking pre. A speech bubble reads: "Ooohh... This isn't... So bad... I'm so f-full... Pressure... Heh, I'm so big, and round... I want... Bigger... More..."

Our poor berry boy can start saying goodbye to mobility pretty soon, he's almost spherical now... But I'd say he's beginning to enjoy it? 🥴🫐

Illustration of a young man turning into a giant blueberry. He's almost spherical now, extremities completely bloated and spread out in an awkward starfish like position, trying to keep his balance as long as possible... His erect dick is poking out of his tattered underwear, and he's blushing, embarrassed about his predicament. A speech bubble reads: "Fuck, I'm becoming totally round... I feel so heavy, I don't know how much longer I can keep my balance!" And another thought bubble reads: "God, why am I so hard right now? This is insane! But... Why does this feel... Good?"

It looks like those pants didn't stand a chance against that juicy butt! 💦

And unfortunately for Alex, I'd say it doesn't seem like this will be stopping anytime soon...

He's turning around to look at his expanding ass ripping through his pants with a concerned expression. A speech bubble reads: "Shit... My pants! What's happening to me? I'm still swelling all over... When does this stop?!?"

Poor Alex here seems to be completely clueless about what's about to happen to him...

But in case you couldn't tell from the size of the canvas... It's gonna be huge! 😏🫐

Comm from @beetle.zone!
Big ol' Texas knows all too well that if you got it, flaunt it, and he sure does got a lot of it!
A downright enormously hyper-muscle, hyper-endowed Texas from Motorcity is winking and flashing a wide, cheeky grin with his buck teeth biting on his tongue. He's raising both his arms up high and giving a double bicep flex. His flame-print speedo is stretched so thin by his towering hard-on, that the glans is covered snugly, but the bands hover over the shaft barely concealing anything. A little star appears beside his face, and little hearts appear over the top of his glans.

"Ya see now, Rat-tail? I told ya I was the Burners' secret weapon, still don't believe it? Might wanna run for cover, cause this ain't even the biggest Texas gets!"
Drawing of a gigantic, exceptionally beefy, bare naked Texas, and a regular-sized Abraham Kane, both from Motorcity. Texas is posed with his left palm and calves against the floor, and his back arched, yet still he still looms over Kane at this size. He's looking down at Kane proudly, reaching his right hand out to his chest, and nudging his chin from below with his index finger. His massive erection, thick as his forearms and long enough to reach his chest, is pulling his flameprint speedo so thin, it could very well snap apart. Torn-up socks with the same flame pattern cover his feet. Kane's leaning with his back and forearms against the wall, and looking back at Texas tensely. He's fully dressed in his white collared shirt, slacks, and shoes, but his hard-on is pitching a noticeable tent. The scene is a plain light blue interior; a generic Detroit Deluxe building. The floor is cracked all over underneath Texas's weight.

Comm from @whatinsomnia.bsky.social as a present for my buddy @donatzu.bsky.social's birthday, featuring Jupiter (my OC) and his OC Arorás in a downright GODLY arm-wrestling match >:) Who's gonna win?
Two gigantic hyper muscle men are seated and arm wrestling on a very crumpled and dented table in a barred prison, as well as inadvertently frotting below the table, due to the size of their dicks. They are both wearing orange prison jumpsuits and have cuffs around their ankles. Their left arms are doing the wrestling, their rights are behind their backs. Jupiter, on the left, is my space alien character with the ego of a god. He has light blue skin, a graying orange mullet, 2 antennae protruding from the top of his head, rough sideburns, glasses, a flat goatee, and six digits on his hands and feet. The jumpsuit he's wearing is fully opened at the front to reveal his hairy pecs, and has a high collar wrapping around his neck traps. Arorás, on the right, is Donatzu's literal god character. His skin is dark maroon, and his hair is short, slicked up, and dark in the same hue with bright star-like flecks. He has 2 horns on his head, and a full beard, his hairline connected from the chin, to the sideburns, to the scalp. His jumpsuit is torn at the sleeves, and on the back is decorated with with the letters "RGP", standing for Rogue God Prison. Arorás' long, snakey tail protrudes out-of-frame from the jumpsuit's designated hole between the ass cheeks, and curves back into frame with the tip at the height level of his feet.

Thirty years and now he's back: the giant GILF in the Mystery Shack 🥴
Illustration of a hyper muscle Stanford Pines from Gravity Falls emerging from the interdimensional portal in his lab. His shoulders are so broad, and his muscles so thick, that it's quite a tight fit through the portal hole, glowing brightly behind him. His crotch bulge is as wide as his waistline, and sags down to his calves.  He's wearing a cloak, a sweater, sweatpants, and boots, all of which are a dark shade of gray. Additionally, protective goggles cover his eyes, a lighter gray scarf is swaddled around his neck, a strap of a bag reaches across his chest, and lighter gray protective pads cover his knees. Ford is facing towards the viewer and smirking with bravado. His right arm is reaching up to grab the top of the portal's triangle base, and his left hand is grabbing the right side of the decorative ring of glowing constellation symbols, from inside the portal. Both points of contact are cracking and crumbling from the strength of his grip. His legs are bending with his knees jutting forward, his right knee more so, and his heels are scraping down the bottom part of the triangle.  An alternate version of the previous pic. Ford is in the exact same pose as before, but less clothed. The goggles now hang from his neck, revealing his eyes, with eyelids lowered halfway, and pupils looking straight ahead at the viewer. His cloak, bag strap, and boots remain on, but his sweater and pants are off, his massive package snugly contained by just a medium-gray pair of briefs. Another alternate version. Ford is dressed almost the same as the second version of the pic with just one glaring difference: the briefs are off, and his erect shaft and balls are out swinging. His eyelids are slightly lower, and his mouth has opened into a wide, toothy, lip-biting grin.

2024 is coming to a close, so who's the rightful champion to earn the title of thembig's official Biggest Man of the Year? Why, it's Texas; no surprises there! And here he is with some friendly gloating over our two runner-ups, Pete and Ford~
Texas from Motorcity is standing between and looming behind Pete DiNunzio and Stanford Pines. All three men have hyper-sized muscles and erect hyper cocks, but Texas is an order of magnitude even larger then the other two. His arm span is twice as wide as either of them, and his erection rises so high that the head can't even be seen in frame. With his hands reaching out over the smaller two's shoulders, he cheekily wishes them better luck trying to get bigger than him next time. Pete is in a jealous rage, arms craned with both fists clenched. He's cursing Tex out for being so much freakishly larger, going so far as to question how he isn't fainting from all the blood going to his cock. (Ironic coming from him, considering his own hard-on and Ford's aren't any less physiologically impossibly massive.) Ford is gasping in astonishment and curiously reaching over to lay a hand on Tex's skyscraper of an erection. He shortly remarks on how unprecedented it is to witness a being as gigantic as Texas, this up-close and personal, no less.

Mr. Smith, relaxing at the beach before a boat race, didn't understand why he was getting so much attention from you, or what you meant when you asked to "play with that banana". After being more direct, he concedes as long as you make it quick...
An extremely well-built man named Mr. Smith, with hyper muscles and a hyper cock and ballsack, is reclining on a folding beach chair on a sunny day at the beach. Smith has an extremely simple head shape, a regular hexagon extruded around its vertical center, and an extremely simple face to match, mere solid lines as his eyebrows and mouth, and circles with dots in them as his eyes. He has pale, near-white skin, and is wearing a straw hat and a one-piece bathing suit with vertical stripes. His nipples, poking out through his suit, are also hexagonal. He's looking towards the viewer with one eyebrow raised and a bite of banana bulging in his mouth. In his right hand, he's holding that banana with the bite missing. His erect dick is trapped tightly in his bathing suit and reaching up to the underside of his pecs, while his balls hang past his knees. Behind him in the distance is a swath of tropical trees and huts, and to the right of him is the coastline with a few beach towels. A nearly-empty glass of a tropical drink sits on a wooden table beside him. An alternate version of the previous pic. Smith is looking off to his left and his mouth is open in a complacent sigh. His right hand is empty, what with him having finished the banana. His bathing suit is off, revealing his chest and genitals. His exposed nipples and glans are both pink.
