Sisterly Lust is a a choice-based visual novel made in Ren’Py and the first in many I hope to create.


Until recently you’ve lived in a different part of the country with your father. Your parents divorced when you were very little and the family was ripped apart after a fierce custody battle. Your mother took her three daughters home, while your father moved away with you. You haven’t seen your family since and any attempts at communication were very much discouraged by your father.

But now, everything has changed after his sudden death. During your fathers funeral you were approached by a woman you instantly recognized as your mother. She asked if you would be willing to go home with her, meet your sisters and be a family again.

You hesitantly said yes…


The game is built on choices that will have an impact on the gameplay. Each main character has two statistics; Trust and Corruption. Scenes will unfold based on those two parameters. Be careful not to lose the trust of any of your siblings, otherwise your stay at your new home will be a very short one.


All main characters (including the protagonist) can be named, they include the older sister, middle sister, younger sister and mother.


  • Incest (Brother/Sister, Mother/Son, Brother/Sister/Mother)
  • Anal
  • Lesbian
  • Corruption
  • Voyeurism
  • Masturbation
  • Teen
  • MILF
  • Group Sex (Optional)
  • BDSM (Sub & Dom, Optional)
  • Pregnancy (Optional)
  • And much more!

Running the game on Android

You might not be able to start the game due to an error. This could be due to the app not having permissions to write to storage. If you allow Sisterly Lust permission via information screen it should run properly. I'm working on a possible fix in future versions.

So at the end who can leave with you.  Asking about side characters wise.


Very nicely done.  A couple of minor continuity issues I noticed:

If the movie with Rachel doesn't go well, I don't believe that Mrs. Steel shows up in the store, but in a later conversation there's still a reference to "that horrible woman in the store" or something like that.

The first night on Belugio at dinner, the pizzas get eaten, then they are magically whole again in the following scene.

Typo in a conversation with Rebeca, "Your not going to encase it" should be "You're ..."

Thanks for the compliment and spotting those errors, going to fix those in the next release!


I feel like I should say a little more since my post was mostly criticisms and the game is so good overall.  First, I really have no interest in the incest fetish, but your game story is so well-done that it doesn't matter.  Second, the use of internal monologue in the conversations is brilliant and often funny.  Third, I really appreciate the options to avoid some of the more extreme fetishes that I actively dislike.  I'll be sure to report any more issues that I notice.


Don't worry, I didn't construe your initial comments as overly harsh. Really like to get constructive feedback, so it was much appreciated.

If you find more, please let me know, always good to fix inconsistencies, makes for a better final product. ;)


Minor typo/tense in a conversation with Liza: "I seemed to have caught a beautiful" should be "I seem to have caught..."


In a scene with Adriana, "her head bended backwards" should be "her head bent backwards".

So i reached Day 39 and then it skips to day 139. Is that intentional or no?

Yes, it is. Not a bug. ;)

(1 edit) (+1)

The title alone was enough to give me jitters, never thought I could encounter so many of my favorite fetishes in a single game and the story line and humor within certainly didn't disappoint either, even managed to get the good big harem ending

Glad you enjoyed it! Hope you'll like the ending of the game which will be released in December.

(1 edit)

Can't wait for it lol


Probably the best erotic games I've played, very good script and the character design and personality is so good and well done, i will hope that someday foot fetish will join your projects. Very well done videogame! 

Thank you so much! Scenes featuring feet have been requested a couple of times, I'm still thinking of a nice way to incorporate it in a story, as it's not one of my personal kinks.


What an amazing game... Good graphics and excellent story!

Thank you Zhalafi!

i transferred my saves from the browser version of this game to the downloaded game on my pc, but now it says ''to be continued'' at day 143, i guess that isn't the last day right? my character is going out of country. please help, it would be really annoying if i have to do everything again.

There's a browser version of the game?

To remedy your problem, you should load the "To be continued" save and rollback (by using the mousewheel or hitting Page Up or Page Down). If you get back to a regular scene at the end of Day 143 you should save your game again and proceed from that point onward.

it didn't work, it still went to the ''to be continued'' screen :(

Ah that sucks. Could you perhaps send me the save file by mail so I can have a look for you? My address is perverteergames@gmail.com

FYI I believe that when a third party adds a browser package to play desktop games, it does not save in the same place. 

I am guessing you have to start over when switching from browser to downloaded.

(1 edit)

I think a third-party likely created that browser version. From what I remember saves are not stored as files, but in the localstorage of the browser. So as Deckardz2019 says, you'll have to start over on the desktop, I think.


Hi first of all I wanted to say that you have created a great game I love the story and the characters i really like this game.

I already played the 0.21v and i just download the last one and i was wondering if i can continu the story directly with in the last version and not start again from the begining?

Thanks a lot Verde! Your saves should carry over from version to version, so you should be able to play v0.22.1 right where you left off in v0.21.


This game is a lot of fun, and the storyline actually draws you in which is rare for a game like this. There were a few times I skimmed over the sex scenes to see how the story was going to unfold afterwords. I can't wait to see what your next project is going to be like.

Thanks Kazamqwe! Hope you'll enjoy the next project, it's heavier on the story, so I hope it draws you in as well.

Does anyone know a guide that shows you the actions to take the achieve relationships with the rest of your family. I played the game fully through but even though i tried to make actions that i thought would lead to a sex scene with the family didnt work. Im probably missing something but i just wanted to know if theres a guide to achieve desired results.

Yes there is one available through Perverteer's patreon

Sister Lust have a lot of stories you can add on, I know you want to move on, any chances someone can help you to keep developing more sisters lust? I will love to keep reading about this family. Thank you for this...

I do understand. The game has been my evening job, alongside my day job, for the better part of two years, so I'm itching do to something else for a while. I'm not ruling out returning to Sisterly Lust at some point, maybe doing a special or something.


Thank you for replying back to me, I do love this novel and im definitely supporting you in the next one.. my imagination is flying with all the scenarios can be done with sister lust.. thank you again.

Hey I've heard about the game and wanna try it out but I'm planning on waiting till the next version comes so I can just play as long as possible. When will it launch?

The next public release will be in December and it will be the last release of the game. I should have a more definitive date for the public release later this month.

Ok cool!

So I updated the game here and downloaded through your website and neither works. I get an error which from what I see on the log is reported as

 Importing _renpysteam: ImportError('No module named _renpysteam',)

I don't know if it is something wrong with your upload or something going on else where but I figured I can't be the only one with issues.

Hmmm, I've never seen that error before, but it might indicate that some vital files are missing from the build. Assuming you're on Windows, do you have antivirus enabled, could it maybe have quarantined certain files from the game?

(2 edits)

Yes I'm on windows and I'll see if I can figure that out as I had this problem with another game too, the only antivirus is what came with win 10 and earlier versions of the game worked.

EDIT: I found a forum about the issue and it is missing files that should be in the game folders. The files are _renpysteam.pyd and steam_api.dll I guess here is the link to the forum


(1 edit)

I've tried one of the downloads and I can't reproduce the issue, unfortunately. The Github thread mentions updating video drivers, but I'm not sure what that could solve as it concerns missing files in the Ren'Py directory. The fact that you have the issue with another game (also Ren'Py?) is however a strong indicator of something interfering on your end. Game optimizers or anti-virus might be the most realistic option, but you already mentioned don't run those.

If you learn more about the issue, I'd be interested to know more about it.

(2 edits)

Yeah it seems to be almost random for me on whether any renpy games will work when I download them and redownloading and installing doesn't fix it. I'm not tech savvy enough to figure this out right now so hopefully someone else can help out.

OK so I just went back through to double check I was actually up to date for windows and I wasn't so now I feel like a complete idiot lol. I updated and now the game is running. Thank you for the help you tried to give me and sorry about wasting some of your time.

No worries, really glad you got it all going! Hope you enjoy the game.

Any info on when the next public build will be available here?  I've been checking back all day :-p

Wondering the same. 0.22 is available to patrons only.

I am seeing that 0.21 stops before any wedding proposal or island escape. Do you see the same?

The scheduled release happened when I was already asleep, but I've updated the builds here too, so you should be able to play v0.22.1 right now!


Thanks! First off, on 21.1, I finally played through my favorite arc- the Bella Sub + Liza (with Meghan and Riley) path. Unbelievable. As good as full harem is, and Bella love, this one is rockin. There are a few inconsistencies here and there (dialogue with Riley implies a relationship with MC's mom for example), but not many.

I am going to play the new version tonight, 'cause I can't wait, but I am also going to toss in some cashola later this week in thanks for such enjoyable content.  

FYI - When traveling abroad, Google thinks that "perverteer" is a slavic word and tries to translate my results into another language. Thanks Google.

Thanks a lot for that great review! Hope you'll enjoy the latest version just as much.

And Google is really weird sometimes. ;)

after i come back from holiday the game just kind of ends and i cant do anything else Day 21 ish

Maybe you accidentally ended the relationships by walking in on people?

How do I open the zip file on android? I can download it from browser but I can't open the zip file even with winzip. I can't use the mega link because the file is too large.

Android shouldn't be a zip package, but an apk. This article details the steps to sideload an APK onto your Android device: https://www.greenbot.com/article/2452614/how-to-sideload-an-app-onto-your-android-phone-or-tablet.html

I mean I often download apks without issue, but the one I get when I click this game download is labelled. zip

Ah right. Seems itch.io automatically zips Android packages when uploading to their server. I'm not sure how to handle zip packages on Android, but you could try downloading from my own website: https://perverteer.com/downloads/ You can download the straight APK from there.

(1 edit)

Hi there is a problem when i try to download the game each time it is downloaded to a certain point but then it stops and it shows me error-forbidden.(btw im on pc)

That might indicate a problem with itch.io's servers. Do you have trouble downloading the game from here: https://perverteer.com/downloads/ ?

Thanks a lot for the reply i ll try to dowmload it from the link

I downloaded on android and got "app not installed". Help

Did you allow installations from unknown sources? You can enable this here:

Settings > Security > Unknown Sources

If that doesn't help you could try to disable Google Play Protect if it's enabled.

Open "Play Store" > Menu button > "Play Protect" > Disable "Scan device for security threats".

Also, did you rename the apk or execute it from an SD-card?

I've also built a arm64 apk for another user with install problems, maybe you could give this version a try: https://mega.nz/#!8PAxhYpJ!7RDJaLiLEA5592t_PUBplFp2BG126dn2AG3ejGkG4fY


Just popped by to say this game is awesome! By far the best written game of its kind. Not to mention the incredible models. I've got to ask, visually, are any of the ladies inspired by real people? Fingers crossed at least Susan is designed upon a real woman! 

Keep up the great work, can't wait for the next installment! 


Thanks Rob! The girls weren't inspired by real people, but do resemble the type of girls I really like (Rachel and Bella). An curvaceous Susan sadly doesn't exist in the real world, I'm afraid.

Next installment will drop here soon in about four days!

Amazing! Thanks for the reply, I'll keep my eye out for it. I'd be lying if I said I wasn't gutted but maybe one day I'll find my Susan 🤣

Deleted post

The public release will be v0.22.1, so yes the bugfix is already included. Wouldn't be fair otherwise. ;-)

The most intense game i ever play, i have finished 4 walk-through of this game ,but does anybody know is it Rachel the only one who can get pregnant? I have try to not creampie in Rachel as the result nobody will get pregnant. But one of my acquaintance who played this game told that he can get Bella pregnant. Sorry to say but pregnancy sex give me the real intense to keep playing this game. So let me know how to get others to pregnant, By the way keep up with this great work. Look forward for next update. Tehee

It's possible to get any of the main characters (Bella, Liza, Rachel and Mrs. Smith/Susan) pregnant. The steps to get there differ a little per girl and are resolved through a conversation with them. In the upcoming public release creampies will also be requirement for the pregnancy routes.


Tq 4 the info, look foward for the update. Great work ever sir/madam 😊

You're welcome and thanks a lot!

Hey does anyone knows why the game dosent want to boot up? Its just saying that Sl.exe is missing or something. What sholud I do

Your antivirus software could have flagged the .exe and quarantined it. If you exclude or whitelist and unzip the package again it should probably work.


I've just completed my third playthrough and I'd like to express my utmost respect for Perverteer's work on Sisterly Lust.
This game blows my mind on so many aspects, it's so smart !

Yes its lewd nature succeeds in providing more than its share of fap material.
But what keeps me playing is all the care to put the scenes together in a logical, progressive way, whatever choices you make and with not one but more than seven primary and secondary partners.
Each of them has a very distinct yet credible personality and is charming in their own way.

Through the story, I really liked how the author deconstructed incest, a very taboo and immoral theme, to a point that in the end, when you think about it thoroughly, there's no reason to view it negatively as long as all parties consent and have fun.
I seldom played a game that encouraged open-mindedness and critical thinking that well.

The player is always free to make choices that feel right to them but it's easy to see where the author stands.
And I must say I'm almost 100% aligned with the values, attitudes, behaviours and religious/political views promoted here.
(apart from the first steps of a certain path with one of the sisters which is borderline consent-wise)

I would rate this game 9/10 because perfection is unattainable and there's always room for improvement.

Perverteer, you well deserve my money.
I'm willing to help you with development on an ongoing basis.
What would be the most profitable way for you ?

Wow Max, thanks a lot for the thoughtful review and the compliments! If you'd be willing to support me on an ongoing basis, Patreon is currently the best platform. I'm on SubscribeStar too, but you'd be missing out on the extras and devlogs I post on Patreon.

(1 edit)

No worries mate, keep up the good work. 

Patreon it is then ! Sorry but I'm not familiar with it, I can neither find you there nor find any link to your Patreon page, even on your website. 

How should I do ? (I'm sure other people would like to know too)

Edit: OK, found you on https://www.patreon.com/perverteer
But I had to manually add /perverteer after the home address. No results found for "perverteer" in their search bar.

The Patreon guidelines are pretty strict about types of sexual content and as itch.io hosts the taboo edition of the game I'm a little hesitant to link to it. Patreon also blocks 18+ content by default, so lewd projects are virtually undiscoverable on their website. It really sucks, but I guess it's something we have to cope with. :(

Thanks for becoming a patron, your support really means a lot!

That is shadow banning by Patreon.  May I suggest checking out Perverteer's page at subscribestar.adult?  I found that to be an awesome place to get any extra content.

Hey quick question, I'm an android user and I'm trying to figure out how to backup my save data. Is it in the app or on this website? Thanks again, and I love your work. Really do enjoy the app. 

Thanks so much! I think you can just copy the save files to an external card with a file explorer app on Android. The saves should be located here: SD:/Android/data/com.perverteer.sl/files/saves/


I just wanted to state how much I enjoyed the game. Cannot wait for the next updates. 

Just wanted to ask a few things however. What are the expected release dates for v0.22 and v0.23? Will v0.23 be the last update for the game and what are your plans for after the final update?

Thanks! The next update (v0.22) will be released here on October 27th. I'm taking some extra time for the last release (v0.23) to get all the endings right. Patrons will get their hands on it sometime in November and it will drop here in December.


Great story, great cg, great script.

I can hardly play other games after playing this one, this game sets new standard for me, it's so good!

Oh and one more extra point for Sweetroll ;)


Thanks so much! Hope you'll enjoy the other project that's cooking here, more on that later this month.

10/10 simply

far the best erotic novel in times....  i've one sugestion... can you devs add footjob scenes and add the footjob in the fetish session. im hope you think about that, its the most popular fetish, 

especially with Rachel, it would look really cute

Thanks a lot Iluminous! Feet are indeed a very popular fetish, I'll think about it, but the inclusion will probably in the next project.

is there anyway to change the names after ive started playing? im pretty far in and didnt realize it would be nice to have my own name in the dialog

Starting from v0.21.1 (available here) you can change the names of the girls on the statistics screen (top right corner of the screen). It's also possible via the Ren'Py console, but that's a little more involved.


Maybe the best erotic visual novel i've played by now. Despite the fact that i'm kind of new in this genre, i strongly recommend it! 

- Plot: 5/5      - Graphics: 5/5    - Game lenght: Long enough to keep you playing for a while.

Apart from the fact that the game itself can take you long to finish, the developer focuses on being able of choosing very different paths trhough the tittle. So you can actually go back and try for another ending. 

Hoping for perverteer to keep working on it!


Thanks for the glowing review, really appreciate it!

Ok I've tried everything but I can't ever get the game to download or run for Android. I got the file extracted but it refused to download. I've been trying to play this for months and it hasn't worked even once for me.

That really weird. There are a lot of Android players and the game seems to run fine for them. Am I correct the game doesn't install? Do you get an "App was not installed" error? What kind of Android device (arm, arm64 or something else) do you have and what version of the OS are you running?

(1 edit)

I know I keep coming back and . Yeah the game doesn't install and I get "there was a problem parsing your pacage" after trying to download the extracted file. I'm on a Motorola g6 and the os is android 9 I believe

Did you allow installations from unknown sources? You can enable this here:

Settings > Security > Unknown Sources

If that doesn't help you could try to disable Google Play Protect if it's enabled.

Open "Play Store" > Menu button > "Play Protect" > Disable "Scan device for security threats".

Also, did you rename the apk or execute it from an SD-card?

I allow installations from unknown sources and have Google play protect disabled. Also I haven't renamed the file or executed it from the ad card. 

I'm really at a loss in this case. Do you have antivirus installed on the phone, or anything that could interfere with installation? It could be that your device is incompatible. I've built a arm64 apk for another user with install problems, maybe you could give this version a try: https://mega.nz/#!8PAxhYpJ!7RDJaLiLEA5592t_PUBplFp2BG126dn2AG3ejGkG4fY

I want to ask a question, i'm playing the game on my android so if I install the latest version 21.1. will my save data be safe or not?  

(1 edit)

Yes, you should backup your saves, unfortunately. They're stored on the SD card somewhere. This should be the location:


I don't own an Android device, but you'll probably be able to copy the files using a file manager application.

Thank you so much. I already found my save data, now i can install the newest version without worries.

Great, glad you got it sorted out. Enjoy the update!


I just wanted to say this is probably the most amazing free erotic visual novel I have found.  You will find me on your patreon in the near future good sir/mam.  Thanks for all the effort you have put into this and not abandoning it.  I look forward to checking out your next masterpiece from the raw beginnings :)  

Thanks a lot for the kind words and for considering to become a patron! The public release of the new project will also be posted here, hope you'll enjoy that one just as much!

dear creator, when is expected date of next version release ?

v0.22 currently on Patreon will be released here on October 27.

Good story but it's very frustrating, if you miss even one plot point you lose 25-50% of the game within the first 10 days or so. Even being careful I've completely lost Rachel every single game and had to start over. There needs to be some sort of way back if you miss something. Some way to pick up a lost relationship.

I'm sorry to hear that. The relationships are a series of choices leading up to the actual relationship being flagged. There's Ren'Py's rollback feature of course, but that only rolls back up to a certain amount of scenes. The best way is to save early at key points, I'm afraid.

How do you view your relationship status with the characters

There should be a heart icon on the top right corner of your screen. You can enable it in the settings if you don't see it.

(3 edits)

Is this the last scene so far?

And also why so far nothing has happened between me and Rachel ?

Note: I have the latest version

Yup, that's the last scene.

I guess you missed the opportunity to have a relationship with Rachel. You need to set up a movie date early in the game and be generally supportive of her ideas and not boast to her.

Is this opportunity occurred before ana or alina scene ?

I want to go back and take this opportunity,
so before any scene or girl or day
I will find my chance with Rachel.

You can propose the movie date on Day 4 if your trust is high enough (at least 4). The date itself happens on Day 6 and is the first time you can sleep in her bed after the date.
