Sister, Sister, Sister Game Walkthrough

Here is “Sister, Sister, Sister” Game Walkthrough:

Chapters 1 & 2

There are multiple ways to get through the game, and I encourage you to experiment. Here, I will detail the two most direct ways to get through the game: the ‘pure Mom route’, and the ‘pure Gwen route’.
These routes will ensure that you see all content currently available in the game.

Pure Mom route:

Insult Bethany in the hallway at school (necessary for the extra scene in the $15+ version). The only other significant choice to make in the first chapter is whether to sneak into Mom’s room or Gwen’s room. For this route, sneak into Mom’s room and find her vibrator in her dresser. Choosing Mom’s vibrator will play the ‘Chloe Masturbating’ scene at the end of the game. The dialogue choice bears no effect on the game, besides a minor dialogue change.

In Chapter 2:

“Well, I did have this weird dream last night…”
“Check out Mom’s tits”
Choose the rest of the dialogue options, then finish breakfast.
“Go find Gwen and Jennifer at the park”
“Be rude”
“The pill”
“Yes” or “No”…doesn’t matter.
Click on the upper cupboard to find Mom’s wine
Click on the lower cupboard to hide it so she has to search for it later
When talking to Jennifer and Gwen, choose either option…doesn’t matter.
“Get closer to the door”
Click thermometer icon
“Raise temperature in Gwen’s room”
Click file folder icon

Choose any option (“Breasts”, “Ass”, or “Pussy”)…only minor dialogue
“Keep going”

This next choice will have a major impact over the next chapter(s)
Click shelf at the top-right of the screen to hide the webcam well
or click the computer or bed to hide the webcam poorly (leads to Gwen bondage ending)
Choose any option (yes, no, of course)
Choose any option (“Are you wearing underwear?”, “How close were you and Aunt Liz?”, “Nothing”).
Only minor dialogue differences. For what it’s worth, the first one is my favorite.
“Sneak a peek”
Pick any options in the twins’ sex scene. I recommend saving at the beginning, as after you get Chloe naked, you can only pick one option (toy, tongue, hand)
Choose any option…only minor dialogue differences (mouth, pussy, ass)
Select the webcam icon
Let the rest of the game play out
If you have the Extra Content edition ($15+ patrons only), the extra scene will play out at the end.

Pure Gwen route:

In the first chapter, insult Bethany, then choose to go to Gwen’s room and click on the clothes hamper to borrow a pair of her panties. (Twins will do the spanking scene.)

In the second chapter:
“Well, I did have this weird dream last night…”
“Check out Mom’s tits”
Select each conversation option before finishing breakfast

“Go find Gwen and Jennifer at the park”
“Be rude” to Bethany
“The spray”
“Yes” or “No”
Choose either option when you run into Gwen and Jennifer
Get closer to the door (bathroom scene is extended due to using the spray)
Click the thermometer icon
“Raise temperature in Gwen’s room”
Click file folder icon
Choose any option (“Breasts”, “Ass”, “Pussy”)
“Keep going”
Click on upper shelf to hide the webcam well
Click on computer or bed to hide it poorly (Gwen bondage ending)
Choose any option (“Yes”, “Sure”, “Of course”)
Go through the vampire scene any way you like. I recommend saving at the beginning, as you can only choose one sex act (hand, toy, tongue) before the scene ends.
Choose any option (“No”, “…your mouth”, “…Chloe’s pussy”, “Chloe’s
Click on webcam icon (scene is extended due to raising temp, and choosing spray)

Chapter 3

This chapter is more linear than the last one, however, there are a couple of specific actions that will determine how things play out in future chapters, including getting to see some extra content.

The only parts that you need to worry about are the conversation with Lauren and searching Jennifer’s room.

General hints for talking with Lauren:

Lauren is sensitive about getting older and likes to be thought of as the ‘cool mom’. Always call her by her first name, and it’s best to be a little coy with your dialogue.

Here are the specific dialogue choices:

Hi, Lauren.
I know, Lauren, I can certainly see where Jennifer gets her physique.
Jennifer left her book at our house last night.
I’m sure I can manage…
Sure thing, Lauren.
While in Jennifer’s room, be thorough in your search. Click on the following items:
Boxes on top of the desk.
Lamp in the corner.
Bookshelf around the door.
Hover around the bottom of the screen and an arrow will appear. Click the arrow to search the other side of the room.
Click on the following items:
Pillows (to hide the recorder…necessary to progress the game)
Click on the large window (it won’t highlight when you hover over it)
Click on the lighting dome at the top of the screen (if you chose the ‘spray’ route in Chapter 2, you will find something in there).
Click the arrow at the bottom of the screen. (It will appear when you hover the cursor over it.)
Click the door to leave.
You will have two more choices to make:
Choose to ‘control’ or ‘be controlled’. Choose whatever you like. It will determine some elements of the next chapter(s) and just comes down to your personal preference of being submissive or dominant.
You can also choose to visit Mom’s room or Gwen’s room. Choose whichever suits you.
The goal in the end scene is to get them completely naked. In order to do that, you can’t order them…you have to give them gentle suggestions. Lead them to do what they already want to do, just as Alessia said.
Have a little fun.

Take off your top.
Aren’t you getting a little hot?
Let the rest of the scene play out.

Chapter 4

There are multiple ways of completing this chapter, and the choices that you make will determine outcomes later in the game.

There are three ‘dates’ that you can choose from, but you can only go on two dates in a given game. The three dates are Mom (Lucy), Lauren (Jennifer’s mom), and Jennifer.
The Lucy and Lauren dates are the only ones that have action scenes, but you should choose the Jennifer route if you want to develop her story further later on.


General hints – Lauren is lonely and only wants to be reassured that someone cares about her and thinks she looks young and pretty.
Walkthrough – Choose the following conversation options to get the best ending of the Lauren date.
I came to see you
What about?
How could he cheat on someone so beautiful?
He’s an idiot
How sexy you are
Age doesn’t matter


General hints: If you try to do this date first, she will tell you that she needs some time to get ready. Go do one of the other dates, then come back afterward. She is scared that you are going to move away and forget about her. She primarily wants to be reassured that you aren’t going to leave her forever. Like Lauren, she likes feeling youthful and attractive. She also likes seafood and wine, and love old-fashioned chivalry.

You look great!
I’ll miss you, too
I’ll visit frequently
Have some wine
You look young
Order for her
Tell her about Bethary
Thanks for the date
Continue the date
At this point, you can do two of three actions. If you spy on her, the date will end prematurely. You should get her a glass of wine, and change clothes (in any order).
Zombie movie
Get closer
Carry her to bed
Take advantage


In order to play this one through to the end, you will have to have searched Jennifer’s bookshelf in chapter 3
Supernatural Romance
Let her choose
That’s it! After you complete two dates, let the game play out to the end of the Chapter.

Chapter 5

The path for Chapter 5 is pretty straightforward, and deals exclusively with Addison. For a general hint, the best way to handle Addison is to be truthful with her. She already knows more than you think and is pretty good at sniffing out deception. If you asks you a question, she likely already knows the answer.
The goal of this chapter is to build a relationship with Addison (by gaining points) this will make her comfortable enough to have some fun with you at the end of the chapter.

That being said, here is the walkthrough!

What are you doing awake?
Good morning.
But why build a big city house in the middle of the country?
Tell the truth
Yes (truth)
That was so fucking hot!
Is this all you do?
Yes (truth)
The next question will add to your overall score with (a) particular character(s) depending upon how you answer.
Big (Mom and Lauren)
Small (Gwen)
In between (Jennifer)
All of them (Addison)
After this, the path branches depending upon whether you are on the bondage path. If you are on the bondage path, simply play through the last scene. Otherwise…
Yes (truth)

Chapter 7

Admit to spying on her
I saw you with Mom
After this scene, the game goes to a free-roaming section.
There are three things you need to do here:
Go to Liz’s bedroom. (Down arrow, then top left arrow)

Go inside (watch the scene play out)
Next, go find Gwen and Jennifer (down arrow, up arrow)
The sex
Next, go find Liz in the kitchen (down arrow, down arrow)
Click the bottle of whiskey on the counter
Truth or Dare game:
The rules of the game are as follows:
There are four levels of truths and dares. If you pick a truth or a dare of a level higher than the level you are on, they will refuse. If they refuse too many, they quit the game and you lose.
Here are the levels:
Level one truths:
What’s the furthest you’ve gone?
Has anyone seen you naked?
Have you seen anyone else naked?
Level two truths:
Have you ever spied on anyone to see them naked?
What sex act have you always wanted to try?
Do you have a crush on anyone in this room?
Who in this room would you most like to kiss?
Level three truths:
Have you seen anyone in this room naked?
Have you spied on anyone in this room while they were naked?
Have you kissed anyone in this room?
Have you fantasized about anyone in this room?
Have you kissed anyone of the same sex?
How often do you masturbate?
Have you ever fantasized about someone of the same sex?
Do you shave your pubic hair?
Describe your first orgasm
Level four truths:
What is Gwen hiding on her computer?
Jennifer, what is your greatest fantasy? ($15 patron only scene)
Level one dares:
Close eyes while they take their tops off
I want to see your best dance moves
Kiss (Jennifer will kiss you)
Level two dares:
Take your tops off
Feel up your partner
Level three dares:
Take off your panties
Touch my cock
Touch your partner’s pussy
Kiss (Gwen will kiss Addison, Gwen will kiss you, Jennifer will kiss Addison)
Level four dares:
Spank your partner
Spread pussy
Spread ass
After you finish the game, let the final scene play out.
There are many, many ways to play through the Truth or Dare game and it make take more than one playthrough to see all the content. One obvious goal is to get everyone naked. There are also some full scenes hidden in there that are triggered by certain ‘truths’:
What is Jennifer’s greatest fantasy?
Describe your first orgasm (for both Jennifer and Addison. Only other team can ask Addison, though).

Chapter 8

This chapter is pretty linear, so the walkthrough is very straightforward. Each correct response adds to your score. You have to reach a minimum score in order to unlock the full end scene, as well as the $15 patron only scene. Here are the correct responses:
It was bullshit
Yes, I can do that for you
Yes, you can trust me
Everything’s fine
Play dumb
Don’t tell her
Invite her to come
Choose either ‘Men’ or ‘Women’ (your preference)

Chapter 9

Chapter 9 is pretty straightforward, but here are the choices to make in order to see the most content.
“Yes, Gwen is…” or “Yes, Jennifer is…”
Choose either one. This will have an impact upon later chapters
“Yes” or “No”
Again, either choice is ok, but will have a bearing upon later chapters.
“I want to dominate her” or “I want her to seduce me”
This determines the scene at the end of the game. I recommend saving here so you can reload and try the other option.
“It’s sexy”

Chapter 10

There are three possible endings in this chapter. The walkthrough will cover the most direct way to get each of them:

Gwen and Jennifer ending:
Note: This ending is only possible if you are not on the bondage path with Gwen.
● Ether wake Addison or don’t. It has no bearing on the game.
● Find Gwen
● Jennifer
● Has she been acting…’different’?
● Find Jennifer
● I had a good time
● Does this change anything?
● So…this is an ongoing thing?
● Go see Jennifer
● Choose Jennifer or Gwen. Has no bearing on the game.

Addison Ending:
Note: In order to get this ending, you must not have had sex with Jennifer in Chapter 8! The only other thing you have to do is to mess up with Mom/Liz and Gwen/Jennifer.

Here is one way to do that:
● Wake Addison or don’t. Has no bearing on the game.
● Find Gwen
● Jennifer
● Has she said anything about me?
● Find Liz
● Tell her about your night
● Yes
● Find Mom
Note: If you had sex with Jennifer in Chapter 8, the game will end here. Otherwise, you’ll get the Addison ending.

Mom/Liz/Addison ending:

This is the ending that I personally consider the ‘best’ one, but it really comes down to personal preference.
● Wake Addison or don’t. Has no bearing on the game.
● Find Liz
● Tell her about your night
● No
● Find Mom
● I had a good time
● Dream (You’ll get a slightly different scene depending upon whether you chose to dominate or be seduced by her in Chapter 9)
● Yes
● Yes
And that’s all! Note that you can turn down sex with any of the characters before you actually go through with it. Choosing who to have sex with, as well as who not to have sex with will have an impact on future chapters.

Chapter 11

The first few scenes play through with no player choices.
When you reach the scene when Lauren catches you spying on Jennifer:
Keep watching
(This will open up another scene with Lauren in Chapter 12 and is necessary of you plan on achieving her ending)
At this point, you will have one of two different scenes depending upon whether or not you are on Gwen’s ‘bondage pathway’. If Gwen comes and joins you on the bed, you are NOT on the bondage pathway:
Truth or Dare OR Hiking (both will get the same result, but if you say ‘Hiking’ you will get a little more dialogue)
Like I want to hug you

If Gwen shows up in bondage gear, you’re on the bondage pathway:

In this scene, you only have the option to Speak or Say Nothing. You’ll get the same ending no matter what you choose, but it will have a bearing on Gwen’s behavior in the future.

Chapter 12

This chapter contains three distinct endings, as well as optional scenes, depending up current or previous choices.
If you achieved the Mom/Addison/Aunt Liz orgy ending in Chapter 10, the chapter will open with a scene involving Mom and Alessia.
If you achieved the Jennifer/Gwen ending in Chapter 10, it will instead open with a scene involving Jennifer and Alessia. The Jennifer intro will have slightly different dialogue depending upon whether you are on the bondage pathway.

After the opening scene, you will visit Mom’s room. If you want to achieve the Mom ending in this chapter, say the following:

If you didn’t have sex with Mom is Chapter 10, the Mom ending in Chapter 12 will be impossible. Otherwise, say the following:

“No, you don’t”
“I want to expand our relationship”

Important! If you say “I want things to be like they were”, it will close off the ‘Mom’ storyline and it will be impossible to achieve her ending in the last chapter. This might be a desirable outcome if you want to try to achieve a different character’s ending.

After this, you will go to Lauren’s house where there is the possibility of a sex scene with her. If you did NOT spy on her in Chapter 11, this scene will be impossible to achieve. If you DID spy on her, say the following:

“Our last visit” or “I’ve missed you”
“Your pretty face”
“I’d like to stay”
“Spy on Lauren”
“Keep watching”
“Answer her”
“Jennifer’s room”

Let the scene play out.

After this scene, you will return home to find that it is evening and Gwen and Jennifer are sitting in your living room. If you are on the bondage path, you have the option of joining both of them. If you are NOT on the bondage path, you have the option of joining Gwen only. The choice is yours, but if you turn them down, you won’t see the bondage ending or the Gwen ending.

If you are on the bondage path, simply join them and let the scene play out.

If you are NOT on the bondage path, say/do the following:

“Join her”
“I like spending time with you”
“Apology accepted” or “You don’t have to apologize”
“We shouldn’t…”
“Let’s take this somewhere else”

Then let the rest of the scene play out.

If you had sex with Mom in Chapter 10, AND complete the Gwen ending in Chapter 12, Mom will be standing outside your door as you finish. This will have repercussions later on.

If you went through the ‘correct’ dialogue path with Mom earlier in the chapter, she will visit your room that night for some action (giggity). If you also achieved Gwen’s ending in Chapter 12, the dialogue will be slightly different.

And that’s everything!

Chapter 13

This chapter has a few ways that things can play out, depending upon earlier choices. Also, some scenes are optional, again depending upon earlier choices.
I’ll cover only the scenes in which you make choices, and what the choices you have to make to get there. (They may be out of order in the walkthrough).

Visiting Lauren’s house (this scene is mandatory):

Your mother still cares

Talking with Gwen:
Pick any options
Asking Mom on a date:

This scene only happens if you scored with Mom in Chapter 12 and​ she didn’t see you with Gwen

Like a ‘real’ date?

Talking with Alessia and the Twins:

When Alessia tries to mind control you, you can either Resist​ or Submit​. It’s your choice, but will have an impact on the story in Chapter 14.

Answering the phone:

If Mom saw you with Gwen, she will call and ask you to come pick her up. Immediately following that, Jennifer will call and ask you to come over. If you accepted the date with Mom, only Jennifer will call. The choice is yours, but will lead to a different ending and will have an impact later on.

Date with Mom:

Do you know everyone here?
​ (You can pick any response here, but this selection gives you the option of having anal sex with Mom at the end)

Like flash me in public?

I’m trying something new in this chapter. If you ‘fail’ the date, you can go back and try again without having to reload the game.

Having sex with Mom:

If you didn’t get too drunk at the bar, you can come back home for sex. This scene is straightforward, but if you asked her about Alessia​ at the bar, you can select whether you want to Fuck her pussy​ or Fuck her ass​. The choice is yours.

Going to see Jennifer:

This scene occurs if you go see Jennifer after she calls you.

Why haven’t they?

You can go home with Jennifer or go pick Mom up. Your choice. If you continue with Jennifer. If you take her home with you, the two of you will have some fun with Gwen.

At the end of the chapter, you will get a different scene depending upon whether you chose to Resist​ or Submit​ to Alessia earlier.

Chapter 15

Chapter 15 is pretty straightforward. The parts where your choices really matter are during the Jennifer hypnosis scene and the ending.

Jennifer Hypnosis:

If you chose to submit to Alessia previously, you will get the hypnosis scene with Gwen. If you chose to resist, you will get the Jennifer scene. Here is the most direct route to get through this scene:

Put your clothes on

Put your arms down or I want to see you

Yes or No

Let the rest of the scene play out.

The Ending(s)

There are three points that you can achieve an ending. The first is a mini-ending and wraps up the Alessia storyline. When you visit her in the forest, choose accept her offer (submit to her) or decline her offer (force her to submit to you). The choice is yours and has no bearing on the other endings.

The final ending comes down to several factors.

Several chapters ago, you had the opportunity to tell Lucy that you wanted a ‘normal’ relationship with her. If you did that:

And you had sex with Addison before you left her house:

You will get the Liz and Addison ending.

If you did not have sex with Addison:

You will get the Jennifer ending

If you did NOT tell her you want a ‘normal’ relationship AND Lucy saw you have sex with Gwen in Chapter 12:

You can choose between Mom, Gwen, Both, or Neither (Jennifer)

If she did NOT see you have sex with Gwen:

You can choose between Mom, Gwen, or neither (Jennifer)

Secret ending:

In order to achieve the secret ending, you have to play through the entire game while remaining a virgin. You can have oral sex and anal sex, but any vaginal intercourse and you won’t be able to achieve what I have come to refer to as the ‘Psycho Ending’ 🙂

This was originally planned to be the ‘true’ ending to the game, but I decided to go in a different direction. I liked it so much, however, that I decided to slightly rework it and leave it in as a hidden ending.
