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!

Bonus Edition

The bonus edition, priced at $15, contains 23 extra sex scenes featuring not only the main characters, but also several of the side girls. In addition you'll receive a set of special renders and a walkthrough guide. 

Language Support

Sisterly Lust is currently available in English, French, Spanish, German and Italian.

Been a while since I last played this, back when the game was finalized.  I see there have been a few updates since, anything new or just bug fixes?

Is there a chance to see the singer again, because I may have missed it, and sorry if you've answered this question already

Actually it's either that no way she will join our harem,since she never came for mc in epilogue,or it is since there is line telling us that she never came,i don't know, actually there is no guide about her.so it's hard to tell.

I thought so, thanks for letting me know 


Good game! I did enjoy this for a couple of days for the low mb required.. unlike other 1gb+ games that's too short.. just disappointed at the sudden jump from day 39-139.. but all in all good game!


Glad you liked it! The time jump is mostly because of the optional pregnancies that are present in the game, they need a bit of time to show on the girls. ;)


Well...that was rather disappointing. After the mother is injured going to the ruins, that was basically game over. From that point on it was all "you wake up" "you go to sleep" until it suddenly ends with everyone having mediocre lives... 

What did I miss?

not enough love points

Well, I followed a walkthrough and got most of it...missed a couple of things despite that...but jolly good game, keep up the good work and all that...

yeah. make sure to never miss an interaction/sexual innuendo with the girls and you should be good

As I remember you only need low trust point for that scene.. mine was like 3 trust points and 2 corruption.. just don't lie to Susan and you'll pass thru it

Can someone please help me with Rachels path?


what exactly do you need help with


This is the best visual novel I have ever played! Thanks :D

Bro there is a Bug that occurs where you automatically don't visit Riley on day 139 and our relationship ends wether we follow her route till this part or not, having 6 wife is nice enough but leaving Riley doesn't feel right, especially due to big . please bro if possible fix it 


Didn't you get a chance to offer her a place to stay on Day 139?

(1 edit)

no bro bug is that part is just skipped (i follow walkthrough) but that scene where you go and meet her in cafe is just not there i guess bug is in code due to which your option of looking for her in mall previously doesn't matter and it automatically selects that we left her,even if we select to look for her

If you leave her to fend for herself in the mall, the relationship with her is essentially over. Or were you able to continue with her afterwards (between day 34 and 139)?

exactly that's the bug,i follow walkthrough so knew exactly to follow her to continue our relationship but regardless of what we choose,bug takes in code as if we let her wander and left her in mall,so the scene in cafe where we invite her or continue our relationship is not there.i guess it's a simple big in code where that choice to follow her or not is taken by codes as not,no matter what we(players) choose.

Could you perhaps send me a save game from that particular playthrough? Is Riley's relationship status set to "Yes" on Day 39 after the mall scene?

(1 edit) (+4)

Came to beat my meat then leave,stayed for the characters and story,left with tears in my eyes.All while my dick was in my hand.This game is great and i cant imagine how long it took to develop.Props to everyone that worked on this project.

The game won't open on Mac in the newest version?


The game could be quarantined by GateKeeper on, in that case you can try the following:

  • Open Terminal.app
  • Write the following command: xattr followed by a space and drag the TFTUV.app or SL.app from the Finder onto the terminal window
  • Press Enter, it should show com.apple.quarantine as a result. If the text is not shown you’ve likely encountered another issue.
  • If the text is shown, type xattr -d com.apple.quarantine  followed by a space and drag TFTUV.app or SL.app onto the terminal window again
  • Press Enter and try to launch the game again.

I think Caribdis has spoiled me with their character models... These ones just looks so off, especially during orgasms scenes where they open their mouths, they look like donkeys. That's not even a joke, they literally look like donkeys...


James is a real friend. love t he game

I don't want to get emails about buying 4 games that are far from finished. I would rather only get an email when a game is finished and the story is complete.

I just finished my playthrough of the game, but I apparently never got this part of it so I don't have a clue as to who this might be (this is just a screenshot from the above pics above)

I haven't played this game in awhile, but IIRC that is a character you meet during your mother's career path.

Adriana is a character who you will be in close contact with if you're accepted by Discreet Inc.

Ah I see thanks, well now I know where I had went wrong with that story path.

Dude, you're missing out.  Some of the hottest content in the game is with this character.

Dude, you are missing out.  She's some of the hottest action.  To get this hottie, you start on Day 4 and find out about Susan's work


It's just a masterpiece! The game was just a lot of fun. Thank you very much!

Game is good, but I'm encountering a problem. The game seems to crash quite frequently on Andriod. Is there any way to fix this?


I love the Dev's other work but I can't play this game if it doesn't have background music. It's a huge dealbreaker for me. Hoping it'll receive an update that adds it sometime soon but I'm not holding my breath seeing as V1.0 has been out for over 2 and a half years.

Yeah  that sucks tho. But there'll be no more updates. The game is finished and I've reached till the end! So u don't have to wait for any further updates i guess.

(1 edit)

Could just find some nice background music online like YT or Spotify. That's what I did.

Artist's intent is very important with BGM, especially in videogames. Using random BGM can hugely affect the mood in a negative way, making a scene feel humorous when it's not, for example.

Any more updates for the game? Eager to see the family become incredibly incestuous!

There is a problem with the 1.1.6 mac release, it won't launch on my M1 MacBook Air, I know it's not my Macs problem as 1.1.4 works just fine, I just accidentally deleted that version.

If the game doesn’t run on macOS it could be quarantined by GateKeeper, in that case you can try the following:

  • Open Terminal.app
  • Write the following command: xattr followed by a space and drag the TFTUV.app or SL.app from the Finder onto the terminal window
  • Press Enter, it should show com.apple.quarantine as a result. If the text is not shown you’ve likely encountered another issue.
  • If the text is shown, type xattr -d com.apple.quarantine  followed by a space and drag TFTUV.app or SL.app onto the terminal window again
  • Press Enter and try to launch the game again.

thank you it seems to work

I tried this and its still not working, any advice

(1 edit) (+1)

Ok I finished the game after 30 hours playing. 
I was completly glued to the story and manage to get my (the?) perfect ending.

This was one of a kind experience. Although incest isn't my thing, I was stunned by the love between them. 

Good job for the game and good luck for your next games !

Question Does the Game/VN link with steam? if so are all the Scenes on steam? is there more Here than on Steam?

No, there's no particular link (not sure if that's technically possible). Apart from the Steam achievements, the paid version of the game here on itch.io is the same.

ok thank you.

Hi its impossible to me to doawload the game (im on android) you have a possibility to this problem ? Thx for response 

Have you tried the direct link from my website?

Hi. I want to know. I'm 5h into the game and just noticed the 15$ version. 
If i upgrade now, did i missed some scenes ?

I just decided to start over with the full version. The walkthrough is really nice ! 

Glad to hear that! If you were 5h into the standard edition you'd likely have missed some extra scenes by the way.

Can i upgrade my gamesave to the extra scenes edition? I already started with the normal version and dont want to lose my progress

on pc download the save file then transfer to the new version android you can try and do the same but its easier to download over the current version

I love this game, I especially love Bella she is the best and possible sexiest sister even while pregnant although she hates the MC at first. I first played the free version and only developed a relationship with Bella and only Married her. Then I got the full version and Married all the Sisters, the Mother, and Iris. I think I should play it again.

But the one thing I don't get is why won't Rachel let you have a relationship with Riley and won't Marry you unless you break it off with her, I hated to end my relationship with Riley but I wanted to Marry Rachel and have her not back out.

What is the story with Rachel and Riley I don't get it..

okay is it your actual family or your step family????


Wow wow wow wow just wow. This game is so indescribably amazing.


-Amazing plot and story

-Hot characters that have real-feeling personalities

-Tons of kinks :)

-Reminds me of college kings, another amazing NSFW game.


-No sound (really the only con aside from minor visual bugs)

I just finished the free edition with marrying Bella and some of the characters stayed with us in belugio and I'm ready to pay $15 for the bonus package.

The most interesting characters to me were Sasha, Sabine, and Miley. I was enthralled from the moment I saw them all in the dream and I just LOVED the story and how they came to visit for the wedding. I really would like to see a prequel to this game focusing on the time with these three as they were easily my favorite characters and I think they have a lot more to offer.

I have a little theory that Sasha represents 'the game itself' or like your lustful subconscious or something. A subtle entity that knows why you're playing this game and urges you to explore new things and 'have all of them' in a sense. This kinda clicked with me towards the end when I was kinda regretting my decision with Bella because I wanted to see the other paths and remembered a line Sasha had said. Sasha seems to give off this motherly, mysterious almost eerie aura and that's something that stuck with me.



i somehow got 11 of the characters pregnant :-{}


Animated intimate scenes?


I cried at the end. I happily married the 3 sisters and the mother, also Adriana. I make 3 of them pregnant, i didnt with bella, i think its because of the dominant relationship. It was a nice travel, very enjoyable. Good game.

Does anyone know how to fix a blurry game?


is this a VR game/is there a VR version?


is it posable to marry all your sisters and mother?




man the space game is ight but i'd love to see another game like this

Hey, downloaded the free version, was convinced and just bought the bonus version.

Great game, good plot. May I suggest making different bundles for different platforms? I'm on macOS and I can deal with the current bundle but users are used to having only one .app to care about, I think it would be a better user experience this way.

Congrats on the game!


In favor of splitting the releases, I'm on macOS 12.4 (Monterey) and SL.app doesn't launch the game. Gatekeeper is globally disabled on my machine, and I have to execute SL.app/Contents/MacOS/SL each time. Launching SL.app doesn't do anything, doesn't even write a log.txt.

Actually, the icon appears and disappears on the dock so quickly that the last icon is slightly moving and coming back to its place. No time for SL app to fully appear.

(1 edit)

have you found a fix for this yet? getting the same problem

Edit, dev commented on this issue already, worked.

"If the game doesn’t run on macOS it could be quarantined by GateKeeper you can try the following:

  • Open Terminal.app
  • Write the following command: xattr followed by a space and drag the TFTUV.app or SL.app from the Finder onto the terminal window
  • Press Enter, it should show com.apple.quarantine as a result. If the text is not shown you’ve likely encountered another issue.
  • If the text is shown, type xattr -d com.apple.quarantine  followed by a space and drag TFTUV.app or SL.app onto the terminal window again
  • Press Enter and try to launch the game again."

Not about gatekeeper, it's already disabled system wide. I'm currently launching manually SL.app/Contents/MacOS/SL.

How many different endings are there?

too many

(1 edit)

i just downloaded the android free version but it just showed the end scene 'thanks for playing'

You probably saved your last game on that particular screen. You might be able to rollback though and continue forward without seeing that "Thank you for playing" screen.

it worked thank you, the problem ( well its not a problem) was the loading scene, because i have played the pc version i try pressing randomly but it wont skip unlike the pc version, i have to wait for the loading scene. thanks for the reply <3
