Just me inspecting the newest city I have taken up into my collection. Neat little things, but yet so fragile at this size. Always gotta be careful not to break anything. :3 Art by: https://www.furaffinity.net/user/furrypur/ #sizesky #macrofurry #macro #furryart #furry

Trynna make up for missin Aggron day. I don't think it'll fit but I'm trying x> The big Gron is @phosaggro.bsky.social ofc lol :)

Art by: @sparktra.bsky.social Big Synth: @pcb303ad.bsky.social What a fun time on this day~ Watch out below ants~<3 Being big is so fun~ No clothes, Holes plugged, ass and thighs swinging, knocking down and crushing everything & anything that's stands in our path~ #macrofurry #protogen

Spent some away time with a lovely blue synth, found ourselves quite pent up after some time away from everything, thankfully @ctsynthad was right there and ready to have a quality afternoon being filled up.

EXTRA WIDE IMAGE AHEAD :3 A synth of destructive weight needs to be well-fed and cared while he's processing all the extra compounds~ Feeling for big large synths recently so y'all have this big lad~ For @kadewolf.bsky.social of his fat synth dragon~! #fat #blob #synth #dragon

After a long day of flattening the northern cities, a change in scenery was needed, down here the ground is much warmer. Shame their cities still turn to craters just as easily. Might go bathe in the ocean after some fun. #blender #synth #macro

Sometimes being a big goober is nice :> Render I made including a lot of friends #synth #macro

Make sure to take your macros out for walks Featuring my lovely bf and pet @neoazureproto.bsky.social who also helped out with the editing. Full res with a little description on my FA see bio.

Taking a seat which had been punished from previous feasts it groaned loudly. Nothing to fear, just an auditory reminder of how much I have gained. This time was different though, it felt like I was getting lower to the floor. (Full on FA) #synth #fatfur Art by @chubbosynth.bsky.social

While clearing out trash around the city, Yuriel accumulated excess oxygen from processing it all. They thought to play a little prank on Jupiter, using that oxygen. Needless to say, Jupiter is rather flustered by the sudden growth. Commission for @sorin-stalbrum.bsky.social! ^-^

Being here for this photo shoot is so tiring. I have not ate a proper meal in what feels like hours but they all say it has only been 10 or so minutes. See the full text on the FA in the comments below. #synth #fatfurs #blob

This fat ass ate one too many pizzas with is compliment of soda and mentos. Now he is on the verge of a food coma and needing some belly rubs. Don't mind all the burps, he is just letting excess pressure out. #fatfur #blender

My first foray into Blender work. PCB can adapt in weight and size to whatever he feels like, don't tempt fate with that cock or else he might make you wish you had a hole as large as that~ CW: Hyper, Donut

just look at this big soft synth~ why dont we show him some appreciation and see how blushy he gets when we start rubbing his fat soft gut~ thingy for @pcb303ad.bsky.social

Did what @ctsynthad.bsky.social asked me to do, may have gone a bit far and made a mess :3 #synth #hyper

Be sure to appreciate the small and big synths out there! Small set of pics for @rixxtheticsynth.bsky.social Synths made by Vader-san

poor bot got a bit too greedy with all his snacks and now hes realising what happens~ thing for me and someone on discord,ill make this a ych for anyone who might want it, $55 for single char(fat one ofc) and $80 for both, dm if youd be interested :3

tried blender on my phone

who knew big puppies could smell this good, atleast dogs have a strong sense of smell~ banana milkshake for the great @.guilio12321

I can't help but love it, even though I got work to do.

Can you help me by holding my balls? They are heavy >//< #synth #hyper #latex

These two lovers enjoy dressing up in all types of clothes, but I think the warmers are staying on no matter what~ ych for @pcb303ad.bsky.social and @neoazureproto.bsky.social

Thicc boi #synth #hyper

Morzsa was invited to try out a new flavour of a weight gain shake :3 Art by the awesome @softakita.bsky.social

This here is why my fridge has stainless steel panels and has the pull area on the side of the door in a little dug out. Although my sausage fingers sometimes get stuck inside, worth it

3/3 Finale He is sooo big~ 🎨= @thewilldpink.bsky.social Give them all the love for this 10/10 art #blob #weightgain #hyper #fatfur

Misty invited me to his recently created Discord server, but it seems that he forgot to tell me how small it was! Now I gotta try and navigate through these cramped spaces... great! >:c Art by: @mistybadplace.bsky.social #furryart #furry #nsfw #macro #sizesky #bulge

I decided to get a huuuuge upgrade in my hardware recently! Though the drawback of this is, that I had to get new XXXXL boxers to accomodate for it. Hope they'll hold and won't tear! :3 Art by: @grosspotoo.bsky.social #furryart #furry #nsfw #hyper #bulge

Feel that every morning, wake up and realize how hungry I am, even after having a large meal at midnight. Always need more

Imagine all the calories id get from this uranium alone~ the good thing is these are super fun to snack on~ just a quick doodle i wanted to make

Portals are my tool of choice to grow and shrink myself, but turns out a certain MistyBun triggered a slow but long lasting growth spurt which lasts even through sleeping. Guess I gotta watch the doorframe from now on... Art by: @mistybadplace.bsky.social‬

Big Protogens need biiig meals to sustain themselves.. but sometimes I overdo it.. Nothing a nap in the forest can't fix! Though the surroundings might get flattened a bit when I roll over. ;3 Art by: @grosspotoo.bsky.social‬ #sizesky #macrofurry #macro #furryart #furry

poor bro is being subjected to inflation cliches #fatfur

Another surge, another day spent trying to keep myself from being so worked up. Found a lovely building to use as a toy. Cum all over and building smushed is a great day for me. Just don't be to close or else you might be in the flood zone~ #furry #synth #macro #vrchat

Renders by my bf who is in it @neoazureproto.bsky.social He found me on top of a high rise, couldn't resist him picking me up, not like I wanted to. Being on such a soft and squishy paw is such bliss, all I wanted to do was express how much I love him. #furry #macro #protogen #synth

Happy 8/8 🫧🫧🫧 Don't have time to make any full render's so here's something I got made from my friend @mistybadplace.bsky.social a while ago and some other past stuff. I expect to see ton's of preys, preds and LOADS of bulging belly's~ >:3 #voreday2025 #voreday #furry #vore

An art comic piece I got from my friend @sparktra.bsky.social ^^ Using landmarks as toys feels so nice~<3 Hard for us macros to see these towers or buildings and NOT help ourselves~ Nice of these people to hand them over~<3 #macrofurry #nsfw #furryartwork #protogen

Apparently it's national underwear day, Time to celebrate! That doesn't mean I have to wear them though right? :3 Sometimes its nice to be naked and let the air flow~ Not like it matters, since most pairs rip & tear because of my size and waist~ #furry #protogen #paws

national underwear day guys this is it this is my day also featuring @velvetbutfreaky.bsky.social and @nebulaproot.bsky.social

Heard it's national underwear day~ It's not much but I got jock on to vary things up, don't trust it too much know, it is barely holding on. One more large meal and it is snapping off~ #furry #furryart #fatfur Art by @chubbosynth.bsky.social

Apparently it's national underwear day? Well then! Have a delivery of some macro underwear directly (in)to your door(frame) :3c Art by: @mistybadplace.bsky.social #furryart #furry #nsfw #sizesky #macro

H-heya guys, got myself into a subby mood and let Neo have fun~ Art by @webberthederg.bsky.social #collared #leashed #buttplug #furry

After my first surge I kinda got out of control, thankfully I was able to find something to satiate my needs while being a macro, sure they won't mind their precious tower being missing up my ass~ Art by @sparktra.bsky.social #furry #macrofurry #analplug #buildingtoy

Look at this year's shark week coverboy! He sure knows how to entertain . . . Sketch for @skullyxl.bsky.social

i dont think fat dogs and latex clothing is the best fit together, what do you think~ i might make this a ych, if yall want one send me a dm, ill probably just take a limited amount (price can be discussed and such)

Heya folks, I'm PCB303. I'm a fatass synth who enjoying spreading love and food. Many shenanigans are about but don't worry, you're not on the menu unless you ask. Below are some of my many sizes. NSFW ones below.
