In short – What’s new? We have also improved other images where Katy had outdated look and in total over 200+ images with 300+ other image assets were added into this update, making it the biggest update we ever made in a record time with breaking 500+ big or smaller visual changes, tons of bugs fixed and added improvements and over 20 individual animations and 9 sexy scenes. Roughly 2+ hours of new content. We recommend using new game to see all Katy’s features.

Katy’s visual was upgraded (including her body in all her poses, emotions, etc.)

Katy’s story will consist of 5 separate storylines directions:

#1 Main storyline – Brother sister relationship slowly becoming something much more.

#2 Studying together – Studying sessions will eventually get out of hand.

#3 Bathroom peaking – Player will be able to start peeking how Katy is having a bath, maybe help her wash her body, or have a bath time together, naked of course

#4 Night messaging – Being together in the night time, one for other when Katy feels lonely and need her brother’s shoulder as someone she could cuddle to.

#5 Family secrets – Player will see how Katy masturbate and she will see him. Next logical step will be to start experimenting and exploring together how far it goes.

Also from now on there will be possibility to masturbate on the bed and on the chair in your bedroom, watching something in private or imagining someone

New content skipping feature:

More convenient way to jump into the right moment. It can get uneasy to navigate in huge VN story content and it could get a little bit confusing, especially when you are a returning player.

According to Ashe Thurman (Leading expert in VN storytelling) we will prepare a simple solution which will look as following:

Series of questions will tell the game how to prepare the save just for you, by your skipping preferences:

This will enable you to skip huge portions of story (which you already played), granting you GUI, skills, locations, money, forward the calendar and read through tons of conversations.

We are listening to your requests and suggestions closely and this is a sustainable way to expand content jumping in the future for us and for your easier gameplay.

No worries, the questions won’t be more than 7-10 based (Based on your selections)

Skipped content will be fully under your control and ready in 7-10 clicks (you could always go back one step or rollback fully to main menu and change your mind to explore only certain parts of the story branches – at least roughly)

Or even simplified visual form of skipping loads of content within few clicks:

*this does not mean it will unlock everything, you still need to play the story, but worry not as we have made 8 character sex scenes available to watch from the first start of the game (increased from 3)

New redesigned game introduction:

We wanted to give a short preview for new players what is the game about. This way new players can have it easier to see a glimpse of what they can expect by playing.

New backstory and early game dream changes:

For 4 years we had written a backstory of the game that will be important as you progress through the story. It is now story-wise ripe enough to expand a little bit into the mystery of what’s behind the world of sisters with short history and a goal for the player to progress in his own story.

Every compelling story needs a long term goal which hero can chase towards, display strong villain character introduction. The Demon Queen from the dream will be soon finally explained in detail and as a cherry on a cake MissKitty2K agreed to coop. voiceover of the backstory with her sexy voice.

(Yup that’s new feature to read out certain special texts and I have to tell you it looks really good with the visual storytelling, and we hope to use it more in the future for major story moments) You can visit MissKitty channel here, she has over 150M views on PH, all related to VN adult games, you can find her channel here:

To summarize it, this update took huge portion of our heart to make and we are still not satisfied with many little details and ideas on our nice to have list are still missing. The only thing which we couldn’t fully complete at all is the task navigation for some Katy’s quest-lines due to time reasons and lack of testers. This will be however fixed in upcoming update.

What’s next? We need to get some sleep as the average sleep in last 2 weeks of our team members was about 4-5 hours at best, while working 16+ daily which took high toll. So next we want to work on new sex scenes with priority over anything else and put them into the game as fast as possible.

So before jumping into any big update we will make a series of sex scenes with patrons vote to choose from and we will release them right away in shorter releases, hopefully 1st one to happen will be as soon as in 10 days. More info in the post in few days.

Enjoy the new update. Thank you very much for your support.
Whole WOS team.

I just got a new computer that came pre-installed with windows 11, can’t run the application.

World of Sisters developper.

Please send us on our e-mail what error it shows or more info about it, we tried it on win11 before and it worked after I think it’s called confirming to run application from unknown sources first popup.

World of Sisters developper.

We are considering on adding ingame walkthrough, we have beta version of this feature which will be released soon.


Stop donating to this trash!!!
Since Jun 9, 2021 (1+ year) this scumbag on developer managed to poop out of his dead brain 0.17.3 ver.

Mind to calculate how many years or development it will take until the final release at this rate?


Not worth even extracting images.

World of Sisters developper.

There were more than 15 releases since year ago (where story reached only till school, and ended there, we keep adding more stuff), There are thousands of hand made images which we created and put together in form of the VN game. I don’t see what makes you so extremely angry, 95% of all visual novels here are unfinished, our game is free and noone forced you to play. We are also working on the game in our free time. You came here only to hate for no reason.

They want us to start over from scratch because of the new updates thats a headache   :wpds_mad: .

World of Sisters developper.

Game tries to always upgrade the old saves, and if this won’t work you can skip content to any game moment quite easily in a bunch of clicks. (MAIN MENU -> CONTENT SKIP) Have a nice day

Good boi


World of Sisters developper.

2 weeks ago we had patreon vote where people chosen 3 out of 12 proposed sex scenes. So we have 2 new sex scenes made of 3 animations in the works which are going to be released within a week and next patreon vote will happen in the following days on our patreon with 10+ sex scenes / scenarios to choose from. These votes are happening regulary on our patreon. Everyone is very welcome to vote what comes into the game next. Cheers!
