Expansion, inflation, stuffing, vore, preg games

a collection by Yttreia 路 last updated 2025-09-06 07:17:43

(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 The little blurbs might get out of date over time, but there's a decent chance I'll notice and fix it.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.

Same as the last Poipole game made by this dev, but now there's a third size stage and the camera zooms WAY out even further.

Idle game made in RPG Maker where you slowly grow women's boobs with milk.

Super short, simple story with a girl being inflated against her will. Not much to it, but eh, it's like five minutes long.

RNG-focused minigame about stuffing various objects into women. Very simple game. Has a cheat button in the options menu.

Roguelite sex. Upgrade your sex to sex better. There's impregnation and tons of cum, but no pregnant bellies and no cumflation. Kinda wonder if the dev will add those eventually. The gnolls are tubby though.

Tiny minigame starring "the girl JoJo". Very basic gameplay, complete it in like 30 seconds.

Barebones RPG Maker game for a Game Jam, but contains a lot of big hyperpregnant bellies. Beatable in like 15 minutes max.

VN about asset size theft. (Haven't played in a while though.)

Jank thanks to being so early in development, but it's a sex sandbox that contains both BE and cumflation. Pretty good size cumflation too.

Annoyingly simple, but short and sweet inflation, expanding a Jolteon with electricity and making her cum.

Breast expansion and tentacles, but hooo boooy that's a lot of waiting, very slow.

A linear kinetic novel where you "text" with various girls and they end up inflating their bellies. Art is all AI images/videos, if that bothers you.

Super unfinished Jam game made for a Jam that only ended up getting one submission (this), haha.

Anyway, bunnies, sex, cumflation, egglaying, sell eggs, upgrade stuff, hire more bunnies, pregnancy everywhere.
Very buggy, but the idea's there and it's still probably worth a try.

Chat with the only woman from that other game I reviewed; befriend her, avoid saying anything to piss her off, then expand her boobs. There's also a paid $1 upgrade that lets her boobs go a bit bigger and I understand it also unlocks a popping ending?

Yttreia says

Decent collection of Rodrigo's minigames. All free (minus a couple demos). Not super sexual, but there's plenty of inflation. Fun dev to watch, I think he's mostly on dA and BodyInflation these days.

Very simple expansion story idea generator that spits out ideas for basic plotlines and such. Probably doesn't belong in the collection though, TBH.

One of Milkis2000's more basic "games", basically just an "expand button" that fills her belly and tits with water, plus a rub button and a belly jiggle button.

One of those "make food to fill orders for people" games, but the "food" is all fat dog things that you swell with fillings.

Basic and simple WG clicker, though the "WG" has a bit more of that "inflated", rounded look. UI stinks and the game's TOO simple, but it's so short that you don't play long enough to suffer.

Also the game's images AND coding are done via AI, which probably explains the UI.

It's a CYOA but with fetishes and a hamfisted puzzle minigame that constantly interrupts you to pad the play time.
You can 100% it in about half an hour to an hour, as each "run" is really short.
Great art, great animations, great humor, great size for the inflation path.
Best played on Steam for the achievements.

"We have Super Deep Throat at home", the game. Built-in cumflation/milk mechanics, and character customization.
Kinda jank, not as moddable as SDT, and the dev's got some stick up their butt about trying to hamfist some VN thing into it like some kid adamant about jamming a triangle peg into a circle hole.

Create slime girl (guy TBD) with sliders and colors and toggles. Big, small, shapely, flat. Not much to say, TBH. Good sizes.

Yttreia says

RNG-heavy inflation/GTS/BE game based loosely on Big Time from Burger Kurger.
Pump girls (like 6 I think?), try not to pop them, get them dangerously close to popping and deflate them a bit for free timer boosts.
Clothes ripping, boobs growing.
Lots of character customization for the player, too.

WARNING: you will hate the RNG aspects. Good luck.

Your miles may vary depending on model picked, but it's an AI CYOA text/story generator focused on expansion and pregnancy and such, even having built in stats and a 3D character viewer. It's highly recommended you connect your own AI and not use the dev's for a lot of reasons.

Hate these kinds of games and wont play them, but it's a "make potions to satisfy customers" sim game, but with a fuckload of expansion kinks crammed in, ranging from breast expansion to blueberries.
A bit more "puzzle-y" than most.

Yttreia says

Use three slime women to unbirth matching slimes and bring them home while you avoid black slimes. Huge bellies. Simple gameplay. Dev seems to have given up on finishing it, though. Still worth a play.
