A downloadable game for Windows, macOS, Linux, Android

Looking for a fresh porn game? Chest Expansion delivers exactly that — a porn adventure available on Windows, macOS, Linux, Android.

Breast Expansion is a minimalist inflation breast clicker game where you click and click until her boobs grows. This game is a spin off of Abdomen Expansion!

HOW TO PLAY

As I've mentioned, this game is a simple minimalistic clicker game. 

However, that's only on the surface!

This game has a "Birth" feature in which you effectively reset the game in exchange for a permanent boost. Gamers have two options on this:

  • ASSIMILATE: Each point of this gives a permanent bonus auto clicker.
  • CONSECRATE: Each point of this gives an increase to all upgrades.

SUPPORT ME!

Hi, Abdomen Expansion is my first game! I made this game in around 2 months as my first game as I learn the free and open-source Godot Engine.

I hope you guys support me on this game! More updates will come soon!

its so sad that the game is now free because of Collective Shouti wanted to get the game by buying it (not that i have the morey sadly) not because its going to fall apart ╯︿╰

NGL, $7 for one of the most basic, grindy, click-heavy clickers on the internet is just bananas. Might as well spend an extra $3 and buy Atlyss instead.Can't believe I didn't notice the price on the other one, yeesh.Man, for how click-heavy your games are, you might as well pay us for wearing our computer mice out, heh.Take a look at any of the major clicker games out there.There's all kinds of upgrades for both active play and idle play, and various upgrades work off percentages, or interplay off each other. In most of these games, you get MOST of your income via idling or by some little side minigame thing, and heavy clicking is only necessary for players that build that way (or in the case of Cookie Clicker, those click frenzy things.)Seriously, I can click about 18/sec, but I don't want to, my mouse is (relatively, for me) expensive and I'd rather not put 1m clicks into it or make my carpal tunnel worse.Go play a couple decently-rated idle/clicker games, get inspiration from them, this "plus click plus idle plus click plus idle" stuff is what you'd find in some no-effort rip-off mobile clicker game full of diamonds and ads that is only this simple so the dev can just use math to make the game go on forever to milk people of their money.
