Recommending Breast Expansion Games Archive (2021)

[Fredricton3D]

Yes, I hate when I'm searching for BE games and they are 75% M2F, that isn't BE in my mind, its gender change which I'm not into.

Meh, for me it depends on how it happens. If it happens after the initial change from m2f, then I still think it falls under BE.

Related: I hate that when I'm trying to look for "inflation" games, a ton of the search results are from off-topic conversations about IRL economic inflation, and when I'm trying to look for "expansion" games, the search results tend to include a lot of stuff about "expansions" for games, or whatever.

Anyway, on-topic: (and no, I didn't check to see if these are mentioned in the thread yet.)

, an online PVP game revolving around transforming yourself or others, it leans pretty heavily on almost roleplaying with other players, but it has a decently extensive transformation system and you can fill your breasts with different things, force people to lactate violently, whatever.

, a text game (with some pictures), again, it's loaded with tons of transformations, which includes a load of different ways to fill or grow breasts, both size and quantity, yadda yadda.
3. Trap Quest, a text Roguelike-ish game where you explore many levels of a dungeon, where everything is either trying to rape, mindbreak, or transform you, and again, there's tons of ways to expand your breasts, either by being hit by loads of bimbofication effects, getting air needles jammed into your boobs, or straight-up magicking up some implants into your chest.

, sure, you're "feeding" the girls, but all the food you give them boosts their boobs, belly, or butt. Making their boobs bigger is the goal 99% of the time, and expanding the other two is only a good thing in certain circumstances, so the vast majority of your time is expanding boobs for the biggest profit. The game plays like a really gimmicky match-3 game that only has one column of things to match, and the dev is adding a combat minigame for some reason, IDFK.

One Question, why does most of the BE Games have so little BE in it or like only a few scenes... I mean there are more than a hand full of People who likes or loves BE-Games or BE in Games

Hope one day there will be a really nice Game with BE in it, but actually really well done. Like with Unity or UE.
Does anyone know If there is a Game that features well made BE in it?

Because most of the Games are VN's or Textbased Games :/ (I mean I like VN's but there are so many that like are half done or so.)

I believe its because game devs use the same poses for their model for multiple scenes. Open any image folder in a renpy game and it will be "Bob talking" and they use that image every time you talk to Bob. Any change in body type requires the game dev to create new poses for every transformation. I know terminal desires has you make a choice of boob size, so the Dev needs to create 3+ sets of poses for every new scene he creates.

Like Stridestar basically said, most devs aren't able to really overdo it with the content because each change to the base character's design means they have to double/triple/quadruple the amount of effort it takes to make the game AND vastly increases the game's filesize. This is all multiplied yet again by if there's any kind of mixing you can do, like inflating breasts while stuffing her, or if there's some kind of character customization mechanic that allows for tattoos or skin color options.
See:

a dev who really ONLY does this kind of stuff (though it's mainly forcefeeding, muscles, and WG, not boobs, sorry.) Each game is ultra simple, usually just one location and one girl in three or four poses, but each of these tiny games take up nearly a full gig.

The only way a game can really support having loads of customization and many breast size options and whatever else is if the dev decides to make the game in a full 3D engine AND have access to models that are built for all those settings, whether by modeling them themselves, commissioning 3D modelers, or using something expensive like Daz3D.
Not only are full 3D kink games fairly rare, but expansion/inflation is still a pretty niche(-ish) kink.

There's ways to do the same thing in 2D. Nursery Dimension is a good example of that. It uses Live2D to have dynamic breast/belly sizes, and all the rigging is made to work with it. The game in itself isn't all that great, but the result as far as a BE game with different poses and animations goes, it's pretty good.

Sure its more effort, but more effort on the rightplaces the people will love it

The permutation explosion is death by art. Imagine doing hair (H), tattoos (T), and boobs (B). Each scene requires HxTxB versions and if you decide to add a feature midway through development, you now have to bug check all past scenes. It is a massive trap that people rarely discuss when deciding to include visuals.

There are some shortcuts that can be taken when doing character sprites as you only generally need 1 "body" per pose and can just add on clothes and other stiff onto, but things like CG artworks you might need more work than just painting over it.

I think the best setting for a BE game is a linear story

 

[cyborgturtle]

Like Stridestar basically said, most devs aren't able to really overdo it with the content because each change to the base character's design means they have to double/triple/quadruple the amount of effort it takes to make the game

for sure, i tried doing it once, in the most basic way, and only had 4 permutations (base, BE level 1, futa level 1, and then BE+futa 1) and it immediately became substantially more effort and also made it a lot harder to troubleshoot/playtest, and then you get the problem that even if you spend two weeks making a crazy variety of possible BE levels, people are most likely going to either blow through it or only ever get one outcome so you effectively spent all that time on something most people won't ever see

The permutation explosion is death by art. Imagine doing hair (H), tattoos (T), and boobs (B). Each scene requires HxTxB versions and if you decide to add a feature midway through development, you now have to bug check all past scenes. It is a massive trap that people rarely discuss when deciding to include visuals.

and this is exactly how i felt (on a tiny scale), and once you've started now you're committed to it, then lets say you have a beach scene and want to include swimsuits, a non-BE girl now has two models - normal and swimsuit, but the girl with optional/sandbox BE levels (lets just say 3 sizes) now has 6

There are some shortcuts that can be taken when doing character sprites as you only generally need 1 "body" per pose and can just add on clothes and other stiff onto, but things like CG artworks you might need more work than just painting over it.

IMO the best/easiest way for something like this is how growth academy does it, it's mostly 2d portraits so every girl has the same poses/emotions, and there'll be a flag for her to use 'size 2' (and so on), then it just overlaps the body portion (or i think more specifically reuses the faces), so it's similar to taking a girl and then slightly modifying her exact same image 10 times increasing the bust size and now you have as many images as needed

I think the best setting for a BE game is a linear story

this is by far the easiest way, and i've been thinking about making BE/transformations much less sandbox-y and instead just requiring people to have a certain body type to activate events lol

 

[CoalBurner]

I think the best setting for a BE game is a linear story

It either needs to be linear, or the complete opposite, where there's a full working character customization system with sliders, or at the very least a paperdoll system.

Part of the reason why it's disappointing that there aren't more mods for it for skyrim

Couple more games to post:

has a little BE, but the game is entirely text-only. The whole game can fit on a floppy disk, tho.
4. some fourth game, I'm drawing a blank, I didn't get a lot of sleep last night, heh. I guess I can put Rack 2 here since there's BE chemicals you can use, but I'm pretty sure everyone okay with furries has already played it.

No clue, I've only put any time into the older games, he had a pretty long hiatus right after the Boobjitsu game and I stopped following the guy until recently.

 

[noctambre]

"Sheroni Girls" is a RPGM that has decent breast expansion it in, Main characters are a alien race that can go super saiyan of sorts and in the process get bigger and bustier. there is also a repeatable scene in the science class where teacher pours a growth serum on your chest and your boobs grow in front of the class. There might be more BE also, from screenshots I've seen, but I haven't found those parts yet myself

did you know were i can find it?

 

[JesseBelmond]

First of all, I shall shout-out Mercury12, R P, Senguj, Sniper69 and everyone involved in the following thread, because they have inspired me to create this post. I'm tired of having to scour the depths of the internet to find games of my persuasion, so I seek to help everyone with this post.

The following list archives all of the games I've played that are related to Breast Expansion , or at least the ones I've recalled and/or found in F95zone and TFGames.
This list includes the knowledge I've managed to gather in the last 2 years of masturbatory practices. Breast expansion is by far my prefered fetish, and I want to share it with my fellow perverts. I've tried to not include games -focused- on sissification/gender-changing/futa in the main list (which happens to be a fair bit of games), nor have I included games that left me too underwhelmed, or were graphically horrible. I may list them at the end. Some of the HTML games might be text based though.

As you will see, my preferences skew a lot towards easy games, that's why I include the first section, in case anyone wants to work hard for their fetish. All the games I've written in their respective game categories I consider to be at least a B (or mid-C for the HTML ones) so at least they are somewhat enjoyable in some facet of the game. I've assigned the tiers based on a subjective and personal basis, basically it's my personal recommendation of the ones I've enjoyed the most.

As suggested by tyuiasdf, the list also classifies the source of expansion into several categories, following the acronym InMPSu:
- [In] _Infection, illness or parasites.
- [M]_Magic, potions or corruption.
- [P]_ Pills, chemicals or science base stuff.
- [Su]_Surgery, chambers or machines.
- Additionally, if I don't have a clue, I'll just write [idk] for "I don't know" (please fill these in the thread), and if it fits none of the above, it'll state [O] for "Other".

Too slow/grindy/complex/little BE for my taste, but still worth investigating (Sorry if I'm too harsh with them!):
- A New Dawn (RPGM) [M]: I think I should revisit this title, but it was a bit too dragged out for the amount of transformation it offered.
- Adventure High (Flash) [M]: It includes some transformations of certain companions via hypnosis.
- Alchimia (Renpy) [M]: It's still early in its development, and there is only one BE scene, but it's a good one (just progress through the main story). The art style is also fresh and unique. Everyone should keep an eye out for this project, it's very promising and could make the Renpy list in the future. (Thanks to JDFlash for the suggestion!)
- Apocalypse (Renpy) [O]: One girl increases her breast size when she gets excited. Furthermore, Cyrl's harem sex scene includes the choice of having her breast enlarged or not. Nancy has two small scenes where her breasts become bigger after wearing the Captain Marvel costume. Finally, both Gwen and Debra have FMG and BE when entering the alpha-ray machine (Description updated thanks to EpicLust's input). Good game.
- Autumn Boulevard (RPGM) [M]: As almost all RPGM games, too long.
- BE Witches (exe) [M]: One of the games I should revisit now they've enabled the cheat menu, honestly, I didn't get to the BE part on the first try.
- Bimbo High (Renpy) [Su]: There's just one instance of a girl getting a massive surgery and you get to pick her size. Really easy "hands-on" game, huge breasts.
- Bound by Lust (Renpy) [M]: Very little BE, but it's a really easy game, and quite good.
- Caliross (RPGM) [M]: Basically too long.
- Career in Transformation (Renpy) [Su]: Abandoned Renpy game with a single scene. It's literally 3 minutes long, but maybe you like it. It had promise, but there's not much. (Thanks to tyuiasdf for reminding me of the existance of this game)
- Cloud 10 (HTML) [idk/P?]: TiT 2.0, too complex, too long. Has better graphics tho.
- Contamination: Corrupting Queens Body and Soul (RPGM) [M]: Short game, quite easy to get some scenes, maybe give it a try, could have made it into the list to be fair.
- Corruption of Champions II (?) [M]: I don't really get the appeal of this game, but everyone seems to enjoy it, so I include it.
- Cracking the Second Strain (Unreal Engine) [In]: Really meh game, the zombie stuff doesn't convince me too much, moderate difficulty.
- Cummy Bender (Unity) [M]: Another promising new project. Later in the game you get the chance to buy a scroll that temporarily increases Korra's breast size wantonly for the "Milk" scene.
- Defenestration (RPGM) [Su]: In this case, it's a mix of the first three issues, but I guess if you like that type of game, it's really good quality.
- Divine Adventure (Renpy) [O/M?]: Later in the game, Vados can temporarily increase her breast size when doing paizuris.
- Dungeon Slaves (RPGM) [M]: Potions cause major BE, but there's quite a bit of bestiality and it gets old quick, for me at least.
- Good Girl Gone Bad (Renpy) [Su]: If you fall to the dark side you'll end up getting a pair of implants. Futhermore, there's an ending where the main character gets even bigger (you have to go full corruption) (Description updated thanks to tyuiasdf's input).

(Renpy) [O]: Honoka breasts expand a couple of times. The thing with this game is that each girl caters to a different fetish, so there's a bit of everything, but that also makes it a bit too little in general.
- Harem Hotel (Renpy) [O]: You can get modules for the android starting in the mid-game. Really good game with tons of content, just not much BE.
- Holiday Island (Renpy) [Su]: One girls has the option to go away from the island for some time in order to get implants, but honestly I like almost every other girls better than her, great game.
- Irresistible Johnson (Renpy) [P]: This is a brand new game based on temporary BE due to your chemically enhanced sperm. It's very promising, and will most likely jump into the main list once it's further developed. (Thanks to Kazutoyo for suggesting the game)
- Katie's Corruption (Renpy) [Su]: Barely has one scene if you choose all the corruption options. Minimal, but technically BE content.
- Last Hope (Unity) [M]: As JDFlash has reminded me, it has one Harry Potter themed dream scene involving potions. And all girls are pretty busty. A bit grindy though.
- Lunars Chosen (Renpy) [M]: Very few instances and very little BE, but it's a fun experience.
- Max's Big Bust 2 - Max's Bigger Bust (Renpy) [M]: There's just one scene (that I'm aware of), but it's within the first 5 minutes of gameplay, and it includes 3 characters changing at once, one of which chages their gender, but the scene is really nice.
- Mythic Manor (Renpy) [M]: There's one girl who can steal breast sizes, and does so a couple of time in the late game, extremely good game.
- Nampa Beach (RPGM) [idk]: The translation is so bad I don't even know what should I be doing half the time, the day-night cycle is absurd and I still don't know where the BE comes around, but some recommend it, so try it if you want.
- Ooze Wizard Apprentice (HTML) [M]: This one is a bit foggy in my memory, but I remember it works a bit weird, but it's ok.
- Orange Trainer (Renpy) [Su]: From the creator of Paprika Trainer, this game is based on the Star Wars Universe. You can buy a surgery table for 1000 hypermatter (which can be easily manipulated in a save editor if it gets too grindy), but the change is very lackluster, the "big" option is like a DD, there's no animation and it's just not a game I'd play for its BE content, but it's fun otherwise..
- Ordinary Day 2 (RPGM) [P]: Way too long until anything happens, got raped by a dude in the process and stoped playing there and then.
- Panacea (Renpy) [P]: Couple of varied transformations, quite good, also some muscle growth which is also a nice fetish.
- Paprika Trainer (Renpy) [M]: You can craft BE potions with strange vines. Really tedious to farm and the increases are small. I recommend using a save editor and cheating the process for the time being. However, the Dev has told me they're going to make it easier in later updates. It's a really fun game though.
- Parasite Infection (HTML) [In]: Honestly, just like CoC, and I don't find the alien theme too appealing.
- Peasant's Quest (RPGM) [M]: I don't even know how I should progress in this game.
- Queen of the Seas (HTML) [idk]: Got stuck at least in three separate playthroughs, and thus I've never made it to the part where you may get transformed, and even then it's just Avatar Generator graphics, so it wasn't worth it for me. You may differ though.
- Sugar Baby Galore (Renpy) [Su]: One of the girls gets "real-size" breast implants in the later stages of her storyline.
- Take Over (Renpy) [Su]: At the very end of the game you can transform the body type of characters in a sort of chamber, needs heavy investment, and tbh, I cheated to get money and reduce suspicion.
- Terminal Desires (RPGM) [Su/In]: This game is so fucking slow I never got to the BE part, however, maybe you have the patience to do so.
- The Thickening (Renpy) [M]: Futa alert! However, I still find this game really attractive, great renders. Just ignore the penis of the protagonist.
- Trap Quest (?) [idk]: Honestly, installing it is such a hassle I gave up, maybe if I were more invested in the game I'd give it a try, but people do recommend it.
- Trials in Tainted Space (Flash) [idk/P?]: Same as CoC and Cloud10.
- Unyielding (Unity) [M]: Not too many instances of BE, but still fun overall. You can mostly speed through the game.
- Victoria's Body (RPGM) [M]: Way too inconsistent and grindy for my taste.
- Wartribe Academy (Renpy) [P]: One of the servants (who is a very femenine boy) can be transformed into a woman. However, none of his male private parts are ever shown in any scene prior or during the transfomation, so do with that information as you please.

Unity Games:
- Debauchery in Caelia Kingdoms [M]: Several characters can grow their breast via potions, way easier than it seems. You can avoid most genderbending content. (A Tier)
- The Pill [P]: Easy to swallow game! Basically just BE, maybe a bit grindy to get all endings, but I believe there are cheat sheets to aid you in your quest. (A Tier)


RPGM Games:
- In the Hamlet of Loli Bigtits [O]: For all I care, one neko-loli has 4 stages of growth, don't think it has anything else BE related (and I couldn't care less). It's real good. (A Tier)
- Ordinary Day 1 [P]: The graphics are a bit outdated, but it's an easy game with quite a few transformations actually. A bit slow though.
- Succubus Covenant Generation One: The Cursed Forest [M]: Quite challenging, but saves aid greatly. The BE mechanics are a bit weird, just save before and after defeating AND BANISHING each boss enemy, then reload the save and defeat them once again, but now surrender to them every time. Combat consist of attack->light of avalon->attack a couple of times->heal->light of avalon->repeat. (S Tier)


Renpy Novels:
- Betrayed [P]: Some instances of expansion, not too many though, but it still is worth playing just for the BE content. (A Tier)
- The Breaker [P]: Just one instance (technically two) but H-O-L-Y S-H-I-T, please don't spoil yourself. (A Tier)
- Deviant Discoveries [P]: Maybe a bit meh until you can start transforming people, but the transformations themselves are great. (A Tier)
- Doll City [M]: A sequel to The Doll House, this game contains 4 transformations as of the last update. Gameplay is a bit strange, it's episodic but sometimes it glitches and redirects you to an earlier stage. Therefore I recommend saving after every encounter. (A Tier)
- The Doll House [P]: Prequel to Doll City, short, includes 3 BE scenes. Rather uncomplicated indeed. Great time. (A Tier)
- Give an Imp a Chance [M]: Short but sweet game. (A Tier)
- Hypnosis [M]: Extremely enjoyable game, more realistic proportions. (S Tier)
- Lewd Sibling Duo [P]: Abandoned game, hella hot though.
- Maiden of Milk: Breast Expansion [M]: Abandoned game, quite short but interesting nonetheless.
- Moniker Smith's Bloodlines [M]: Really good game with tons of expansions of all the good kinds, 10/10 if you can tolerate just a tiny bit of blood. (S Tier)
- My New Neighbors [M]: Once again, tons of expansion, awesome game. (S Tier)
- Rad Science [P]: Abandoned game and technically includes genderchanging, but holy molly is it graphically pleasing, if you catch my drift. (A Tier)
- Sarada Training: The Last War [O/M?]: The graphics are meh, it's grindy af, but there's a fair bit of BE.


HTML Thingies:
- Bimbo Life Coach [Su]: Standard "Porn" game, but a better one at that. Extremely grindy at times.
- Candy's Legacy [Su]: Standard "Porn" game, but a better one at that too.
- The Company [P]: Standard "Porn" game, but a really good one at that. (A Tier)
- Enchanted [M]: Standard "Porn" game, but a better one at that. A bit grindy.
- Fake AI [O/M?]: Your typical Avatar Generator game, still nice sometimes.
- Inner Bimbo [Su]: Standard "Porn" game, but a really good one for its age.
- Paradise Heights [M/P]: Honestly, this game barely made it into this tier, there's a bit of BE here and there, but at least it's not porn!
- The Repurposing Center [Su]: It's text based for the most part, but quite good and easy.
- Who Wanna be a Bimbo [O]: Your typical Avatar Generator game, still nice sometimes.
- Whoremaker [P]: Standard "Porn" game, but a better one at that. Really grindy.
- XXXivilization [M]: Grindy but really good (maybe just a playthrough is enough, there's no replay value tbh). (A Tier)

Executable:
- Chichi Miko!! [O]: Every character gets several scenes, one at a time (save when you get the choice to pick one character and then reload when you finish each storyline). Such gigantic bosoms, great game. (A Tier)

Other Mentions (M2F, Futa, games I have not played [but have seen mentioned in posts, and thus I cannot confirm 100% the quantity and quality of the implementation] and so on) (TL;DR Buyer Beware!):
- A Struggle with Sin (RPGM): It's one character named Natasha, but they get huge and I loved it ~True Draco Heritage.
- A Virtual Taste of Unfaithfulness -Young Wife's Indulgent Life (RPGM): Haven't played much of it, but a BE scene occurs fairly early in the game. ~Crimson Emperor.
- Accidental Woman (HTML)
- The Allure of Wanton Cove (HTML)
- CNT University! (RPGM)
- Crisis Point: Extinction (?): It has a breast expansion status that you get by getting caught by a special vine in specific zone leading to a change in every sex scene. Too bad the boobs deflat after you cum. ~Sinicero
- Degrees of Lewdity (HTML): It has a solid body part expansion / shirinking system. ~Sinicero
- Dungeons of Oblivion (Unity)

(HTML) + Neo Free Cities (Unity): As recommended by Yatzeh and fallenarc. These are more or less 3 versions of the same game. It's a game about slaving that includes lots of customization and body modification. The Unity version is an early alpha, whereas the HTML versions require image packs (more info in this thread).

(Current list length: 118 games)

In conclusion, probably I'm leaving out a lot of games, or maybe I've considered them so bad they are not worth including, who knows (at this point, not even me tbh). I hope anyone who visits this thread can manage to discover at least a single new game they haven't played, I know I've definitely had after researching thoroughly through the back-streets of f95zone and TFGames.

Thank you for your attention, please feel free to expand our collective knowledge further in the comment section.

Hi, i have discovered "Hypnosis" thanks to this thread, and i'm looking for an other game.

I enjoy "moderate" et slow BE like in the beginning of Hypnosis, but with a different graphical style.

With HS models, clothes are fixed and always at the good size, i wonder if it's possible to have tight clothes during the BE.

For now, i'm going to try Endowed
