(Mostly) games full of inflation, expansion, stuffing, whatever makes women get bigger in various ways, mostly boobs and bellies. The little blurbs might get out of date over time, but there's a decent chance I'll notice and fix it.
Be aware, I probably wont include any completely broken, unplayable games. Also, I'm pretty biased against VNs and RPG Maker games, and there's almost no chance of any male-focused games to show up in here, but a few might.
Very solid, early demo. It's a shmup where you shoot the clothes off a giant woman to make her more nude, and/or shoot the enemies to gain love points which make her boobs grow, or both. The gameplay loop right now is collecting achievements, but the dev plans on adding more girls with more types of transformation/expansion. One's going to be pregnancy, IIRC.
Better art than the last game.
An "organ physics sandbox" where you can inflate, fill, stuff, and optionally burst a girl via her organs, using water, tentacles, whatever.
Pretty basic toy, good for screwing around with every now and then though. Playable in-browser too.
Not for me since it's male only AND another RNG-based game, but it's what it says on the tin, "Russian Roulette, but inflation". IIRC it's a fan remake of a similar, abandoned(?) game on Itch. Better art here though.
Currently (Feb 7, 2025) it's a tech demo with stuffing, vore, and WG. There's a male and female option, but everything in the game is temporary since IIRC the dev plans to swap the model out entirely for a human one like the previous game?
Still interesting to play with for a bit though.
Super basic faux-rhythm game where you spend the whole game looking at the right side of the screen while a woman is fucked or cumflated on the left.
Punch fruits into box, punch fruits IN box, ding the bell, and a giantess appears to drink the juice, her boobs swelling up as she drinks. Very mini minigame, fun for a quick run, despite the jank.
Super basic top-down shooter where beating the game gets you a belly to look at based on how many times you were hit.
TOO basic, IMO, but I'm sure someone likes it.
Couldn't be(e) bothered to do more than one run though.
Lewd breast expansion suika (with other expansion types planned). Easier than usual. Infinite breast growth too, apparently.
As you can tell by the thumbnail, the art is the weak point.
Type words in, get magic coffee, give to her, hope it isn't spooky. A lot of words do things, and about 90% are horror.
There's pregnancy and breast expansion content in here, preg takes 9 cups to get full size. Use sexy words to start sex, and use "human" or "reset" to turn her back to normal.
Almost 100% male, but there's a couple girls(?) to unlock too. It's a WG Roguelite where you eat a ton of stuff and get fat while exploring dungeon floors loaded with lots of RNG death. Beg RNGesus for mercy, and cross your fingers that the silhouette of a character you're looking at turns out to be one you like with a skill you enjoy.
EDIT: also you only have a dude (and a custom slot) to start with, so if you want a girl, hope you unlock one quick.
Hyper overinflate a giant lumpy balloon woman in what's effectively a walking sim set in a small room. Inflate and pop her, or deflate her and have the dev effectively make fun of you for deflating someone in an inflation game.
FEELS unfinished thanks to how little freedom you get in the "plot", you'll think you're missing something, some big alternate path, but nope, that's all there is.
Also, warning: the artstyle is more "horror" than sexy, giving off that veiny bulging vibe people do when they're making fun of inflation fans.
Side-scrolling open world survival game with lots of sex and monsters and whatever. There's also now a cumflation and pregnancy mechanic, though it's super basic and only serves to up the difficulty.
Craft a base, build workbenches, it's that kind of game.
The game's early in development, but seems like it'll be interesting.
Super early in development, but you zap women with science to make them bigger in different ways, and getting to the end of the content (after like 5 minutes) unlocks a shop that gives a few more transformations.
Another one of those "potion mixing games", this one's super simple and there's not much content yet, but there IS a breast expansion mix.
Dev has no immediate plans to update it though.
Haven't played it yet but it's got breast expansion. I'll have to remember to try this out after an update or two.
Shmup with a gimmick where "enemies" split after dying.
I'm not a fan of the gameplay, but the art's got a lot of style. If you dislike the gameplay like I do, there's actually built-in cheats so you can make it easier/babymode.
Loads of style in this game for sure, almost worth just watching a playthrough on Youtube just for the cutscenes.
Grind grind grind so you can feed your levels to a vampire cow lady so she can expand her boobs and give you permanent stat buffs. VERY incremental, tons of resets.
It's not as lewd as it sounds, unfortunately. Also the dev was given a bunch of art for free to put in the game, but the ONLY art that really mattered would've been the cow... but she doesn't have any.
Hilariously easy brothel sim game with no way to lose. Loaded with sex poses to pick from and like, 6 sex categories you need to cater to in the game.
The anal category has where you can stuff things up their butts, and one of the options is pumping her full of air (there's also an enema option), but belly expansion isn't implemented yet.
EDIT: dev abandoned it already, and no, the belly inflation never got added, oops.
RNG-heavy, old-timey dungeon crawler for sissification, TG, bimbo, and submission fans.
There's a ton of random fetishes and kinks in there too, which includes cumflation, breast expansion, and even air inflation. This includes floating off into the sky because your tits are too inflated.
The undo button is paywalled, so just savescum a ton instead.
Sex sim "clicker" game based on that meme build in Minecraft that fucks a sheep with an end rod. Early access, very basic gameplay.
After some updates, there's more to unlock, including a new, NEW bust size toggle and a thigh size toggle too.
Currently, like, 4 girls to pick from now, IIRC. Lots more content than before.
Dev removed the grind for now, thankfully.
Super basic, early-dev "move woman left/right, catch fattening food, skip everything else" game. No powerups, just eat cake and whatever, watch her get fatter.
Simple arcade minigame where you inflate women with a bike pump as they get taller and bustier. Try not to overinflate them, they'll pop and end the game. Good customization.
The goal is to keep the pressure gauge super full without popping her, but the size of each pump is complete RNG so.... ehhhhhhh...
You'll try skirting the edge for the time limit extensions and pop her instead, I don't think there's a safe way to do it.
Put pump in Jirachi's mouth, pump until hugely inflated. Simplest game this dev's ever made, I think. The dev likes secrets but my quick skim of the game didn't find any.
Also it softlocks the game when I hit the zoomed-camera button.
Contains feeding, burps, farts, customization, and both an Eevee and a Vaporeon. Ironically not much belly rubs.
You can plug them up so they can't burp and/or fart. If completely plugged while really gassy, they'll inflate forever, heh.
Couldn't really get into the game myself, but people seem to like it. You feed a lady to earn points so you can feed her in more and better ways.
Simple, grindy, and repetitive, but it's an RPG with different Pokemon getting bigger in different ways as they level. The AI art in the game is about C+ tier, I've seen worse, seen better.
Current content: BE (Nido+Eevee), FMG (Char), AE (Ratt).
Super unfinished text game that's been abandoned. Contains some inflation and a bunch of other fetishes, but the game's just nowhere near done.
You might still get some fun out of it for a little though, I guess.
It's a pretty janky, super-basic clicking game (no upgrades or currency, just clicking) where you pump up famous anime girls by clicking an obscene amount of times, almost a parody amount, starting with clicking a hundred times to go up to the next size, then click a thousand times to go up to the next size, then click a trillion times to go up to the next size, then cli-
Game full of little secrets and an obscenely inflatable Poipole, quite recommended.
A hand pump, two automatic pumps, and even inflation via sucking in air from balloons.
There's also a secret popping toggle. (No gore, just BANG, skinny.)
