X64 drank some new experimental oil… He’s now swelling into a cute belchy berry! <3 #inflation #burp #burping #belch #expansion #blueberryinflation #blueberryexpansion

X64/Xander anxiously holding his swelling gut as it bubbles and groans, it’s slightly transparent showing the bubbling juice within. His buttocks are also notably full of blueberry juices.

Same as the first image, but X64’s tummy is now visibly forcing bubbles back up his throat, making him let out a huge guttural belch.

X64: ‘BUUURRRPPH!’

BM333 should really look where he’s flying sometimes… #fart #hyper #ass #butt #farting #fartfetish #expansion #analvore

BM333 stuck between X64’s buttcheeks, visibly blushing and struggling between his two enormous mounds of rubber.

X64, now having his bowels loosened by BM333’s struggles accidentally unloads a massive bout of flatulence right onto the poor drone, but judging by his blush and swirly hypnotized eye… I think he likes it~

Too much oil, Xander? #fart #fartfetish #fetish #butt #hyper #ass #farting

Back view of X64/Xander, he’s shyly smiling. He knows you’re staring at his fat ass, which is the main focus of the drawing. He has his clawed hands on his large stomach.

X64: “Oh… umm… Hey…”

Same image as the previous, but this time… his big gut is grumbling and gurgling, not agreeing with all the oil he drank earlier. His expression is now mortified, realizing it’s already too late.

X64’s bowels: “GRGL…”
X64: “Uh oh…”

Same image as the previous, but his booty has given into exhaustion, belching out a huge pink cloud of flatulence. His ass is visibly flapping and rippling as he farts, due to the force. His gut hasn’t shrunk a bit and it’s still rumbling, all that fuel is gonna take a while before it’s all farted out~

X64’s ass: “PHRRRT!”
X64: “OOHHH… UNNNHHH…” [he’s enjoying this, if you couldn’t tell]

shy robot in a tutu :3 #fart #hyper #ass #butt #farting #fartfetish #expansion

Xander/X64 in a pink tutu, with a pair of pink panties underneath, he’s looking at his ass sticking out from the bottom of the tutu and is visibly super embarrassed.

Same as the first image, but now he’s farting.

old drawing I made for pride month #fart #hyper #ass #butt #farting #fartfetish #expansion

Xander/X64 looking back at the viewer, his ass has a big bisexual flag painted on it. The paint is still wet and dripping.

Same image as the first one, but he’s farting, causing the wet paint near his buttcrack to be forcefully ejected off his butt.

Same image as the first one, without the bisexual flag.

Same image as the second one, without the bisexual flag.

Xander inflation, yahoo! #inflation #expansion #belly #bellyinflation #bellyexpansion #airinflation #ass #butt

X64/Xander, shocked and a little embarrassed at an air hose behind him, that’s pumping air up his ass, causing his belly to inflate and expand. His inflated belly is the focus of the drawing. There’s a little icon in the bottom left corner of the back view showing the hose shaking into his ass.

To celebrate both my own birthday tomorrow and @skyofsunnyfox.bsky.social ’s birthday in a few days, I drew Nameless having a little encounter with Xander~ #hyper #ass #butt #buttcrushing #booty

Back view of X64’s bottom half, Nameless (skyofsunnyfox’s OC) is flattened against his right buttock, he has swirly eyes and has notable marks on him from being sat on for so long.

Same as the first image, but without Nameless (x64’s prolly apologizing profusely to nameless)

I need to draw more blueberry stuff, here’s my drone guy with a big berry booty #fart #hyper #ass #butt #farting #fartfetish #expansion #blueberryinflation #blueberryexpansion

BM333/Bumper looking back at his big rump, it’s expanded even bigger, turned a deep dark blue, and is full of blueberry juice which is making his ass visibly slosh and gurgle. All the lights on him have also turned a deep blue.

Same as previous image, but now BM333’s juicy booty is pumping out an enormous amount of wet, juicy, blueberry-scented gas.

dottie flirting with xander #fart #hyper #ass #butt #farting #fartfetish #expansion

DOT85 cuddling up to X64’s belly, meanwhile X64 is embarrassed, looking behind himself at his enormous ass.

DOT85: “you’re so big, blubber boy~”

Same image as the previous, but they’re both letting out big clouds of flatulence.

DOT85: “nnfff…”

An animation I made of a gassy X64 ripping fat braps! (All stomach gurgle and fart sounds used [except the last one] are from Orange Zemenar’s fart fetish SFX pack.) #fartfetish #fart #fartanimation #ass #hyper #butt #booty

Shake it, Dottie! #monobutt #inflation #expansion #assexpansion #fart #farts #fartfetish

Dottie/DOT85 shaking her big round monobutt, it’s notably a lot bigger than it usually is as she inflated it before she starting shaking ass.

Same image as original, but this time, the shading is darker, and the air in her booty is rushing out in the form of a large but soft fart.

DOT85’s ass: “PHLRRT…”
