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)
- Dwindling Away (RPGM)
- Eileen ~The Curse of Futanari Succubus~ (RPGM)
- Event Girl (HTML): It is another HTML gender bender / feminization but forced game with BE by surgery. The protagonist got trapped in a machine and he wakes up in a future where he's a woman and must pay for a huge debt. ~Agent Cooper
- The eWardrobe (HTML)
- Four Elements Trainer (Renpy)
- Free Cities (HTML) + (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).
- Friends Of Mine (HTML)
- Hard Times in Hornstown (HTML)
- Hentai High School+ (?)
- Here Comes the Messer (RPGM)
- High Jinx! (Renpy)
- Human Alteration App (HTML)
- Jack-o-nine-tails (QSP)
- Key of Egg (RPGM): I haven't played this yet, but judging from the preview pictures, it looks like there is some BE. ~Crimson Emperor.
- Lacto Escape (RPGM)
- Lilia's Livelihood ~Girl, Tentacle and the Wonder Island~ (RPGM)
- Lilith's Throne (Java)
- Locked Away (Renpy)
- Magical Camp (RPGM)
- The Making of a Slut (HTML)
- Nursery Dimension (Unity): Made by the same people who created Lilia's Livelihood and Rain's Rave. (Not finished yet) ~Crimson Emperor.
- Perverted Education (HTML)
- Press-Switch / Illia's Mansion (Renpy)
- Rain's Rave ~The Girl Who Writhes Among Tentacles~ (RPGM)
- Secretary (HTML)
- Sheroni Girls (RPGM): Has decent breast expansion it in. The main characters are an 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 the teacher pours a growth serum on your chest and your boobs grow in front of the class. ~JDFlash.
- SiNiSistar (Unity): You get it as part of a bad ending later in the game ~Flesh Prison.
- The Sissy Girlfriend Experiment (HTML)
- S.L.U.T. Academy (HTML)
- Succubus Reborn (Unity): There are 2 cards that can do that, (giant emulsification and mik's miracle). The girls also learn paizuri, through the knowledge of oppai ~decker2 (Thanks to BigJohnny as well). Note that you need a translator to play this game in English.
- Succubus Tales Chapter 1: Nicci's Revenge (RPGM)
- Succubus Tales - Chapter 2: The Relic (RPGM)
- Suddenly A Girl (HTML): Another game from the author of Sheroni Girls. It's been updated consistently and is also a gender bender corruption game. You start as boy that got transformed in to a girl by your stepdad. You can start with different body types and in last update got a Bimbo transformation path. ~Agent Cooper
- Summer of Shame (?): It is a gender bender/ feminization/ sissyfication game with also BE by pills and medical procedures. The protagonist got one size bigger in the latest patreon update. ~Agent Cooper
- Vixens Tail: Duskvale (Ren'Py)
- Has a breast expansion potion with at least 1 scene. Also most of the characters are futa. ~Crimson Emperor.
- Witch Trainer: Silver Mod (Renpy)

(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.

Thanks for that list;
Just a correction for my ongoing game Apocalypse which you have kindly listed, there's more than "just one girl increases her breast size when she gets excited". Cyrl's harem sex scene does include 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.

Thank you so much for responding! I'll update the list accordingly.

You removed your previous line "one girl increases her breast size when she gets excited" which is on top of what I listed.

One add is Good Girl Gone Bad has an ending where the main character goes even more. I think it should be in the main list. But you have to go the corrupt path to get it.

"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

Thank you for your contribution! I've added the game to the list.

Gave a 5 star rating for the thread. This is a great growing resource.

I would like to request that you add the type of transformation included in the game because that might change which games people try. Some people like magic or pills or surgery. Would be very helpful to have those details included. You could even use symbols like PS for plastic surgery, M for magic and C for chemicals and pills and alien technology. Maybe we need more letters I don’t know.

I'll think about that system and implement it asap, definitely worth looking into it.
