Holstein Girls

An Adult Visual Novel about breast growth and cowgirls.

Inspired by games like Lab Rats and Persona type games, this game will take place over many in-game days where you will be able to choose whose story to progress in between main story beats. There are 9 total girls who you can romance during the main story.

This is not a short game, partially due to there being 9 girls each with a storyline. It’s a slow burn. If you are looking for a visual novel to entertain you for longer, this might be for you.

This game focuses on breast growth/transformation, lactation and pregnancy mainly, including incest. There are 6 main endings, each specialising in a further fetish (futa, multiple breasts, breast pregnancy, hyper sized breasts, egg laying, and milking), with 10 sub endings in each (harem + solo endings for each girl if you only pick them).

After you complete the game once, you will unlock the ability to skip to the end to make achievement hunting easier, so it is in there, just not on your first playthrough.

It’s pretty hot actually. If you liked Lab Rats and you’re turned on by lactation and impregnation, you’ll enjoy it. On the minus side, there’s the hovering of the pictures, which are often crude & exaggerated, and I would rather there was more focus on impregnation and less on already heavily pregnant bellies.


It’s heavily obsessed about unnaturally large boobs, impregnation and milking. Would have preferred having a more variety of kinks but it’s still good. Wish there were more drawn out sex scenes, instead of just words used to disicribe what’s happening, but again still good. I’m glad that the mc at least is not a totally moron or faggot like most MC’s out there. Giving it a 6/10.

Ridiculously huge boobs from the MC’s actions, with no way to moderate the boob growth without stalling the story line. Way too big to be sexy, imho, and no animation anywhere in the game, let alone any sex animation. The story line did hold my interest enough that I did play through most of the game, but I felt like a sucker in doing so.


Also, this copies the gameplay from Lab Rats but he didn’t know how to balance the time-management stuff to make it more engaging. Lab Rats has three daytime phases and does a good job of having content for all three phases, while this game has too many of the girls in the mid-day phase, which is also the only phase you can make a serum, unlike Lab Rats. If you need a serum in this game, there’s often zero possible interactions with a girl in any of the three time periods.
