Gravenous Glutton: belly stuffing + pregnancy management (updated 10/25/25)


alternate non-itch download link: 744.17 MB folder on MEGA

This is not my first game, but it is my first adult game, and I made it because I realized that a horny game developer should not need to wait for someone else to create a game that caters to their fetishes (while omitting the ones that they don’t have). I made it for myself, but it ended up being sexy enough that I decided to publish it.

The goal is simple: make her as big as possible. The mechanics, however, are designed to be more complex than just “spam eat until belly meter is full, look for capacity upgrades, get to max size, start gooning”. Key features include:

  • stomach capacity AND intestine capacity
  • stomach and intestine capacity increased up to 3x by stretching the stomach
  • belly changes shape as contents flow from stomach to intestines (afaik i’m the first person to do this and I hope it becomes the new standard)
  • 40-day pregnancy, growth occurs automatically at 4:00 and is heavily reduced if daily calorie requirements for a healthy pregnancy are not met
  • birth (no special cutscene, just basic animations)
  • impregnation minigame with controls designed to be mechanically similar to something you already know how to do IRL (skip by pressing enter)
  • multiples up to 3, not luck-based, awarded based on how well you did in the minigame
  • temporarily exceed capacity limit after fasting
  • exceed capacity limit even further with up to 5 stacks of munchies
  • belly touching, with jiggling, tummy sounds, moans, and hiccups
  • random fetal movements
  • hidden achievements that unlock upgrades
  • belly stuffing streams that earn money based on how much food you eat and how much bigger you get in 1 hour. features interactive feeding
  • medications that can be bought with money and provide benefits like increased hunger, instant digestion, restoring missed growth, and a special secret
  • local saves for PC and android
  • worryingly detailed descriptive text

Planned features/updates include:

  • some use for excess calories
  • ability to restart without wiping your old save
  • even more worryingly detailed descriptive text

Things I will not add:

  • significant weight gain
  • breast expansion (not because I don’t want to, but because of technical limitations with koikatsu)
  • air and water, probably
  • anything involving another person, I am socially inept

you want weight gain? too bad! you guys already get PLENTY!!! do you have ANY idea how difficult life is as a belly fetishist who prefers 2D and isn’t into weight gain??? go make your OWN game and leave me alone to spam refresh on akane’s pixiv page
(I am open to minor weight gain, but nothing more than what Bready from Nikke is packing)

big ups to fierylion for establishing the prototype for this genre (A Bellyful Life), even if he doesn’t know me and isn’t interested in developing this type of game anymore. I pay my dues to the OG.

Have fun! The game is not hard, but you should be.

So far, it’s short and simple and the payoff is very much there! Definitely worth a shot if you’re into stuffing.

I know some of these words.

Follow that strong vision, Baconfry! I look forward to seeing where this project goes next!

Art and text are great

Is it possible to view achievements?

it is now~

I also have support for local saves, but I’m keeping that version separate on itch while I develop the in-game settings menu where, among other things, you’ll have the option to start over with a new save if you want

This update is good.
