VN - Ren'Py - Completed - Holstein Girls [v1.55] [CowgirlDev]

TLDR: So imagine Lab Rats but with breast expansion and a few more girls. Also a lot of pregnant sex scenes. Very long and wished the ending had different stuff.


The main character does a similar thing in lab rats where they put a serum in a girl's drink while they aren't looking or something similar. Breast expansion gets anime levels of big but not too gross. Although some of the character render looks wack like there's clipping.

Really enjoyed the many different combinations that can arise. In true sandbox fashion, I found a different bit of dialogue when doing things in a different order (mainly with the mother and daughter and the final ending). The final ending takes into account whatever combination of girls you "max out affection with" and does something different.

Some stuff that kinda sucked was that it was very long with no clear indication of when it would end. [It takes to like day 110 ish to end]. The achievements are tedious to get. 3 Achievements (outlined in gold) unlock a special scene. The solo one is a wedding scene for each girl seperately, the different serum endings follow this new girl taking the drug, and then the all achievements is her pregnant (not worth it).

I wished that there was a few different harem scenes. Kinda sucks that a lot of the poses used is just them doggy style with breast pumps. Wished there was a scene with them wearing cowgirl costume (honestly how did the dev not do this) and a harem wedding scene.

Also speaking of the endings, I was not prepared for the random other fetishes to just pop in. Spoiler, it's futa, egg laying, nipple vagina, insanely massive breasts, and 2 pairs of breasts. The last 2 make sense for the theme but wtf for the others.

These are supposed to be short or something? Well there's no character limit.

This is still one of my favorite BE centric VN ever. It isn't breaking the mold in terms of plot, nor is there any expansive character development. This game just delivers what you're seeking. Despite it being my favorite BE centric VN's, it doesn't quite make the excellent rating. There are a few reasons, but it doesn't have any animated sex scenes; it doesn't have posed sex scenes complete with the player; while it has a lot of leeway in terms of choices, the strict order of events prevents any serious deviations when crafting your own walkthrough; and, on a more personal taste level, the ending is somewhat lackluster. There isn't any sort of checkup on your expansive family, and your lover(s) assumes the same milking position for a "sex" scene.

Either way, it's short but delivers a lot of quality BE for those who have similar interests and tastes.

I loved the plot, the different choices, and the possible endings.

Graphics were not stellar, but the rest of the game compensated for it quite well. Was disappointed by the lack of animations, but better that than bad ones.

Multiple playthroughs, no means to even achieve the solo endings or at least it isn't clear what the prerequisite is to start doing solo endings.

0/5 due to "imagination" being needed for the "sex" scenes.

0/5 due to multiple endings being Laura and (other girl) no solo.

0/5 due to gameplay not being clear enough on how to avoid bad ending.

A solid game, especially if you are into its main kink - breasts expansion. Otherwise, you might soon get bored by repetitive progression and lack of visuals. The game likes to tell, not show, and while the writing is quite good, the images are rare and not great. Still, it's a good experience - playing a finished game that knows what it's doing

This game is extremely hot don't miss understand me, but it is boring and repetitive, maybe 2 hours worth of grinding if you mash thru the text for minimal returns , every character is surprisingly unoriginal, and all the sex scenes are a single image maybe two if you are lucky with cringe worth dialogue, still busted about 3 or 4 nuts over the course of 2 runs but with the large amount of games out there this one is sadly quite average.

Even though it's quite simple I enjoyed the progression.
The render could be better, looks like something from early 2000

Not sure I'll bother to see all available endings in this version, but I did save prior to one of the last branches.

Rated: 4/5
Based on: v.1.55

Great combination of BE, Breeding & cowgirl theme. These games are pretty rare and this one is pretty good.


Only downside is no animations, but still a great game with fun characters and very little to no grind.

Easily one of my favorite games recently. Not bogged down with unnecessary grind or too much plot. Reminds me of Lab Rats 1. Worth it, bought it, need more.

I'm not sure what else to say. Just padding this review to get to the 200 character limit and make the website happy.

Okay, so this is just a very good, and fairly short game. And the mechanics are fairly straightforward, once you know them, which isn't 100% explained in the game, only about 90%.

But still, good.

The main character isn't super nice, he is feeding essentially an aphrodisiac to people, BUT, he's not an asshole about it, and there isn't shown a darker side to it, not really. The closest thing is one of the sub endings for one of the characters, where she goes a little mind breaky, but beyond that, the game is great.

Here's a bit of a breakdown:
Each morning and evening you pick what you do; Talk to a girl (maybe give her a bit of the breast growth serum), train a little, get some more serum, etc.
You can see the progress with the girls, and there is only a choice in which girls you go for. So don't worry about making mistakes.

Then, at some point, maybe you've corrupted all the girls, and they walk around with tits bigger than god, you get a choice of how else to physically transform them, afterwhich you get the ending.
And the choices for the extra transformation are just the perfect cherry on top. I'm personally very much into one of them. So yay me.

Aside from that, the characters are nice, the models are fine (Not great, not bad, not boring. Just fine). The story is decent enough and fairly light hearted. So if you're looking for that, and some very good breast expansion and lactation porn, this is probably the best there is.

I liked it enough that I paid author a little bit, despite the game being free.

A very compact experience. You want big tits? We got em. You want impregnation? We got that too. You want cowgirls? Check and double check.
The only time it varies from its initial concept is the various endings, which all throw a wrench in the works of the core concept, if I may offer my opinion. Of course, you have the option to avoid adding anything strange in the final moments, but it leaves me with a lackluster feeling, like your choices are to take a massive leap or stay where you are. It's my singular gripe with the game—the rest is excellent—aside from the fact there's not more of it.
I also have two other minor notes:
Don't worry about calendar management—I wasn't being particularly smart with it and I made it a couple of days to spare regardless—getting all the girls to 10 and reaching essentially the 'max stats' required for the achievements.
Grammatical errors are few and far between, and mostly consist of capitalization being lacking at the start of some lines. Some other lines are also a bit confused as to who's saying them, but it's easily ignorable.

Great game with plenty of kinks. I'm not a boobs guy but I still enjoyed what this game had to offer. Holstein Girls is pure fetishism and I liked it a lot.

The dialogue is pretty spicy. Good maledom games are hard to come by, and this is one of them. The incest content also doesn't hold back at all, which is great. The characters say some pretty depraved shit regarding incest and I loved it. It's nice when a dev isn't tied to Patreon's guidelines, which allows them to just write whatever they want.

Despite Honey Select's limitations, this developer clearly went above and beyond with the presentation of the kinks. I don't know how to explain it. Let's just say you get exactly what you're in for.

I also love how your progress with certain girls affects some of the lines you see. There's some good replay value here.

It pains me to give this game only 4 stars, because I've never played anything quite like it. The reason why I don't give this a perfect score is because some things are a bit lacking, especially the endings.

I've done three harem playthroughs so far, always picking a different serum modification for the ending, but the endings play out the same way regardless of what modification you choose. The changes are purely cosmetic, and sometimes not even that. What disappoints me the most is how even the dialogue is all the same with minimal differences.

The sex scenes are a bit strange. They don't really happen within the environment. There's just a static background image behind the girls as they "float" in different positions. MC's body doesn't even show up. I don't know why the sex scenes are like this, but it makes them very uninteresting to look at. The text is infinitely better when it comes to sexual content. The standing sprites are nice, but the characters are stiff as they lack different facial expressions and poses. The game also lacks breast collision, which means the girls' arms can go right through their tits in very obvious and jarring ways.

It's also very hard to tell whether you've seen all of a certain girl's scenes, because there is no indication anywhere other than the X/10 relationship progress. There is no CG gallery either. I mean, the sex scenes don't even have conventional CGs, so that's no surprise.

Keep in mind that I haven't played the latest version that apparently has bugfixes and some new scenes, but I believe everything I said here is a solid representation of what this game did right and what it did wrong. I'll keep an eye on it, though. Maybe I'll be pleasantly surprised with future updates. This game gave me 23 hours of entertainment so far and there's definitely potential for even more.

Gameplay is okay even if you have no real choice but an illusion of choice.
Girls are okay, visual are okay.

I got two main problems:
1) the way the girls appear as image above the background, and not "in" the scene.
2) the fact that for a game about breast expansion, the author didn't care at all to manage the collision with the breasts. Scenes are the same with big or little breasts. But when an arm can go easily to the pussy for a masturbation scene with little breast, the same do not work with bigger breasts.
Since breast expansion is the main purpose of the game, that makes every image with big breasts broken... and that means more than half of all the images i already saw.

Too bad.

Not a lot of games out there that do breast expansion, and even less that do it well. Game does a pretty good job with a reasonable story. There' s no real freedom in how big or small you make them if you want to see their story which is ok but could use some work. Also sometimes the jumps in breast size would be bigger than expected (which is fine again) but would be nice if the progression was slower and more controlled. Would even think that having the ability to temporarily grow or alter sensation would work well. Would love to see more games like this but either with more incremental adjustments or customizability.

Like Lab Rats 1 for hucow fetish. Has music, decent writing without grammatical/spelling errors and couple of ending variations. Structured like an OG trainer so lots of content as well.

Kudos to dev for not feature-creeping and releasing a proper full game. Respect.

I mean, it checks all my boxes, even some I didn't know I had. It's got decent writing, the models look good (yes, even the...unique ending ones), its got multiple endings, and some uncommon fetishes. Overall? fun game, good for those who like to hunt for achievements and endings and such.

If you like cowgirls and breast expansion/lactation/pregnancy, you'll love this. It's well-written and has a good amount of content. My only beef is that the endings feel like they are more or less interchangeable except for the specific fetish renders, but the core game more than makes up for that.

My first impression of this game was "Yet another one of those boring, poorly written games with a thousand characters and lazy models done in that same generator that everyone uses"

What I found was relatively decent writing and well posed models. Which combined with the satisfying fetish content made this one of the better games I've played this year.

If you're into breast expansion, pregnancy, lactation or corruption, especially involving incest, this is a title you are going to want to play. It sets up and delivers very well and it's not nearly as grindy as people say, considering the writing is on the better side. Just turn on skip unseen and mash control if you're impatient.

Great game, impressed by the full release. Fetishes are well implemented and characters are fun. I personal found the interactions between the women engaging. Hope for more from you in the future. It would be nice to have a galary option (sorry if it does have this I have not finished the game quite yet)

Overall I can only give it 3 stars and I will explain why:

Here we have a game that is quite grindy and that could be improved quite a bit on many aspects, just to name a few:

-Ability to skip a day, skip to final day.
-More work on the menus
-Be able to produce more serums at once.
-Being able to select the girl directly (rather than having to clic multiple times to see each girl).

These are just a few improvements that would make the game feel a bit better, overall the list above are just quality of life improvements, however the game could have been expanded quite a bit, especially on the transformations aspect.

To be fair all the game is just about breast expansion and lactation, then we have a few endings (futa, multiple breast, breast pregnancy, hyper sized breasts, egg laying), you basically choose the ending you want and... that's it.

It's an okeyish game, nothing more nothing else. I can't say a lot about it cause of that, you basically make serum -> drug girl -> see event and repeat until the end. No special gameplay or something that would make me try to get all endings unless some quality of life improvements are made.

To end just to answer a few questions:

Q: Is there any futa on male scene?
A: No, there isn't any futa on male, there are just 1 or 2 scenes about futa x female thought.

Q: Is x fetish optional?
A: Breast expansion and lactation aren't optional, those are the main themes of the game.

Q: When do I get the ending?
A: The game ends at day 115, that's when you choose the ending.

Hope this review helped.
