Grandma’s House Walkthrough & Complete Choice Guide

Article content

This Grandma’s House walkthrough reorganizes the complete multi-part walkthrough by MrBubu into a single progression guide. It focuses on choices that affect the story, relationship points, future scenes and route conditions rather than listing every cosmetic dialogue variation.

The original walkthrough covers the game from the beginning through the later content and uses numbered decision labels such as #001, #092 and #320. These labels are important because later scenes may check whether an earlier decision was made.

If you still need the game, visit the Grandma’s House download page.

How Choices Work in Grandma’s House

Grandma’s House uses two important systems throughout the story:

Relationship Points determine whether character-specific scenes become available.
Decision Flags remember important choices and can unlock or block later variations.

A choice that only changes a few lines of dialogue is usually not important enough to appear in the source walkthrough. If a choice has a numbered label such as #001, it can potentially matter later.

Some decisions also establish broader preferences that affect multiple later scenes. Important examples include:

#011 – Sleep sex
#032 – Watersports with Catherine
#066 – Drinking Jamila’s breast milk
#092 – Like girls playing with each other
#109 – Breastfeeding from Jamila
Other character-specific anal, creampie, spanking, BDSM, lactation, watersports and group-sex preferences.

Part 1 – Beginning Routes and Important Early Decisions

The opening section establishes many relationships that continue throughout the entire game. It is worth being generous with Relationship Points early because a large number of later scenes require at least one point with a character.

Shawna

The first important branch occurs on the plane.

Build Shawna’s relationship through the opening conversation.
If Shawna reaches the required relationship level, the bathroom encounter becomes available.
#001: choose between blowjob or sex.
#002: choose the rimming option.
#003: choose to cum in her mouth.
#004: give Shawna your real number if you want her later route to remain open.

Allison

Allison begins receiving route flags almost immediately.

Push or drop the airport conversation depending on the relationship direction you want.
Take her hand in the car to reinforce romantic progression.
#005: offer Allison the remaining wine.
Carry her upstairs after she falls asleep if you want the more intimate route.

Aaliyah

Get her number at the store.
Ask her out when the opportunity appears.
#008: invite Aaliyah over when she offers to visit.
Later, allowing her foot to continue leads to the footjob #018.

Aiko

At the spa, hold her during the massage for #006.
When the sexual route becomes available, choose fuck Aiko #009.
Later, her route introduces anal sex #027.

Betty

Show interest in Betty at the shop.
#007: peek into the changing room.
#010: choose the titfuck.
#021: finger Betty.
Later, choose I like you rather than ending the physical relationship if you want to preserve her route.

Sophia

Choose positive responses when Sophia is introduced.
#012: kiss Sophia.
#022: finger Sophia.
Her route continues through multiple home and sleepover scenes.

Priya and Paveena

Priya’s wedding storyline contains several choices that are referenced later.

Agree to accompany Priya to the wedding.
#013: pick Priya a rose and continue the kiss route.
During Paveena’s sex scene, #014 records whether you creampie her.

Lily

Show interest in Lily at the bar.
#015: choose the golden shower or drinking option if you want the watersports path.
Sleep-sex content also depends on the global #011 preference.

Enable or Disable Sleep Sex

One of the most important global decisions appears early:

#011 – Do you want to enable sleep sex?

Choosing Yes enables later sleeping-character scenes with several different characters. If you disable it, those variants will not appear.

Tanya

#017: determine the pregnancy state based on the earlier sex outcome.
#023: establish whether you are okay with tasting breast milk.
#024: drink directly from Tanya.
#025: tell Tanya you love her.

Fiona

Look for Fiona instead of simply leaving the bar.
Sneak in when given the opportunity.
#016: finger Fiona and continue until she cums.

Sandra

Sandra’s early police route can develop toward either submission or domination.

Invite her inside rather than simply paying the ticket if you want the sexual route.
You can turn the tables on her or submit to her depending on the dynamic you want.
Her scene includes spanking, anal play, blowjob and other options.

Elizabeth and Catherine

Elizabeth and Catherine eventually become one of the largest interconnected routes in the game.

#030: choose whether to spank the loser during the beach competition.
#031: choose the urine option.
#032: enable watersports with Catherine.
#033: allow Elizabeth and Catherine to play sexually with each other.

#033 becomes especially important because many later threesomes and bisexual scenes check this preference.

Jamila

Show attraction and continue helping Jamila.
#034: milk Jamila.
The lactation storyline expands significantly later, so early positive choices are useful.

Annabelle

Progress through Ophelia’s route to meet Annabelle.
#029: choose spanking during the punishment scene if desired.
Maintain positive Annabelle Relationship Points because she becomes involved in many later scenes.

Jasmine

Choose Not if I can help it when her route begins.
Claim your prize when given the opportunity.
Avoid selecting route-ending options if you want later Jasmine scenes.

Riona

Tell Riona to stay and watch when that branch appears.
#040: stay and watch.
#041: tell Fiona to clean you.
#042: eat sleeping Riona.
#043: finger her ass.

Part 2 – Expanding Routes and Preference Flags

Catherine Anal and Watersports

#045: anal sex with Catherine.
#046: pee on Catherine.
Later scenes frequently check #032 before showing additional watersports content.

Mabel

Mabel’s route becomes substantially more sexual during this section.

#047: 69.
#048: rimjob.
#049: spank her.
Later choices allow cum in her mouth or a creampie while involving Lina.

Karen

#052: play with Karen.
#053: choking or spitting in her mouth can establish the rough-sex branch.
#054: impregnate her.
#055: give her a drink.

Minnie

#057: begin the sexual hotel interaction with Minnie.
Her sleeping scene requires both sufficient Relationship Points and sleep sex enabled.
Later choices include elevator and group-related progression.

Elevator Route

#060: elevator sex.
#061: impregnate her rather than pulling out.

The pregnancy choice later becomes one of the conditions referenced elsewhere in the story.

Jamila Lactation Preference

A major long-term preference appears here:

#066 – Okay with drinking Jamila’s breast milk.

Selecting the lactation route enables numerous later breastfeeding, milk-drinking and group scenes.

Aaliyah and Jada

#067: eat Jada.
#068: finger Aaliyah’s ass.
Maintain points with both women because their routes repeatedly intersect.

Polly

Help Polly when she is in trouble.
#070: spank Polly.
Continue positive Polly progression because later scenes often require Polly to be at least 1.

Ophelia

Choose initiative rather than remaining strictly professional if you want her sexual route.
#081: cunnilingus.
#082: enable the roleplay branch.

Jasmine Advanced Route

#080: rimjob.
#083: spank her.
#084: creampie.

Zelda

#085: let Zelda masturbate.
#086: take her home.
#087: enable the anal-related option during the home scene.

Global Bisexual Preference

Another extremely important global flag appears during Catherine’s route:

#092 – Like girls playing with each other.

Selecting Yes enables many later scenes where women interact sexually with each other, including threesome and group-sex variants.

Mila

Mila has several rough-sex and BDSM-style decisions.

#097: fuck Mila.
#098: start rough.
#099: pull her braid.
#100: choke her.
#101: enable pet play.

Shizuka

#088: agree to punish her.
#103: spank Shizuka.
#108: continue until she pees.
#113: let her clean you.

Riona and Fiona Group Route

#104: 69 with Riona.
#105: have Fiona eat Riona’s ass.
#106: cum swap.
The group variants require the bisexual preference #092.

Breastfeeding from Jamila

#109 – Breastfeed from Jamila becomes another persistent route condition.

Choosing the breastfeeding route unlocks many later milk-related options involving Jamila and other characters.

Part 3 – Mid-Game Routes and Larger Group Scenes

The middle section increasingly checks earlier preferences rather than treating every scene independently. Keep an eye on the decision IDs you selected in earlier parts.

Sexual Preference Chains

By this point, the following flags become particularly influential:

#011 – Sleep sex
#032 – Watersports with Catherine
#066 – Drinking Jamila’s breast milk
#092 – Girls playing with each other
#109 – Breastfeeding from Jamila

If a scene does not appear despite sufficient Relationship Points, check whether it depends on one of these earlier preferences.

Elizabeth, Catherine and Other Women

The Elizabeth/Catherine route begins intersecting with more characters. Choices involving cunnilingus, rimjob, sleep sex, watersports, ass play and group participation can influence later variants.

When the game asks whether women should sexually interact with one another, selecting those options generally requires or reinforces #092.

Annabelle and Ophelia

Continue both routes rather than focusing on only one character. Their individual Relationship Points are later checked for shared sexual scenes.

Asami

Asami develops into a major recurring character with numerous preference flags involving:

Public sexual activity
Watersports
Anal play
Submission and humiliation
Group sex
Interactions with Catherine

If you want her broadest route, continue choosing her sexual options and maintain the earlier relevant preference flags.

Twins

The Twins route repeatedly checks whether their Relationship Points have reached at least 1. Later scenes expand into group sex and bisexual interactions.

Police and Legal Characters

Sandra and several later authority characters build upon earlier dominance/submission choices. When the walkthrough shows a Relationship Point requirement, keeping the character at 1 or higher generally preserves the later route.

Part 4 – Advanced Relationships

This section introduces substantially more multi-character scenes. Earlier relationship and preference choices now matter more frequently.

Anal, Watersports and Lactation Routes

Rather than functioning as isolated scenes, these preferences begin linking multiple characters together.

For example:

Catherine’s watersports preference can unlock additional Asami/Catherine variations.
Jamila’s breastfeeding route expands to other lactation scenes.
The bisexual flag can enable women to eat each other out, clean each other or participate together during sex.

Group Sex Requirements

When a threesome or larger group scene does not appear, the most common reasons are:

One participant has 0 Relationship Points.
You rejected an earlier sexual preference.
A required numbered decision was never enabled.
The scene belongs to a different route variation.

Use Decision IDs as Prerequisites

Do not ignore an earlier decision just because the immediate scene already finished. A choice such as #092 can still be checked dozens of scenes later.

Part 5 – Later Character Routes

The later walkthrough greatly expands the number of characters involved in shared scenes. Relationships involving Catherine, Asami, Elizabeth, Jamila, Annabelle, Ophelia, Debbie, Zelda, Mila and others increasingly overlap.

Keep Relationship Points Positive

Many later scenes use simple conditions such as:

Character is at least 1
Another character is at least 1
Previous choice was enabled

For a broad-content playthrough, avoid selecting responses that explicitly reduce a character to 0 or -1 unless you intentionally want to close that route.

Existing Preferences Continue to Matter

The later parts do not reset earlier route choices. Decisions around bisexual sex, sleep sex, lactation, watersports, BDSM, anal sex and impregnation can continue changing later scenes.

Part 6 – Advanced Choices

Ophelia and Annabelle

Progress both women before their shared content.

#297: facefuck them.
Annabelle and Ophelia Relationship Points determine which scenes appear.

Jamila

Jamila receives several advanced scenes:

#299: fuck her in her sleep.
#300: finger her ass.
#321: drink her milk.
Later scenes include anal and continued breastfeeding content.

The sleeping option requires the earlier sleep-sex preference where applicable.

Asami

#301: have her clean your fingers.
#302: grope her in public.
#303: show off Asami publicly.
#304: give her a drink.
#311: make her pee.
#312: anal sex.

Sandra

If Sandra has at least 1 Relationship Point, later home scenes become available, including #307 cunnilingus.

Debbie and Zelda

Some Debbie content requires the earlier Zelda/Debbie threesome state.

#308: go with her.
#309: drink Debbie’s pee.

Mila

Her rough-sex route continues with:

#313: choke her.
#314: slap her.

Catherine

#315: let Catherine give you a rimjob.
#316: let Catherine clean you.
Her bisexual interactions still depend on #092.

Betty Anal Route

#320 – Anal sex with Betty becomes a later prerequisite for other characters, including Matilda.

Lily Watersports Route

If you previously chose the Lily watersports content, later options expand into:

#322: pee inside her.
#323: pee in her butt.
#324: pee in her mouth.

Elaine

Elaine receives a substantial late-game route:

#327: eat Elaine’s ass.
#328: fuck her.
#329: Elaine pregnancy state.
#330: double creampie.
#331: clean up.
#332: cum in Elaine’s ass.
#333: fuck Elaine’s tits.

Dean Nelson

When Dean has at least 1 Relationship Point, later scenes include:

#337: spanking.
#339: facefuck.
#340: slap.
#341: anal.
#342: second facefuck option.

Jamila and Shizuka

Later shared home scenes include:

#343: drink Jamila’s milk.
#344: anal with Jamila.
#345: fuck Shizuka.
#346: pull Shizuka’s hair.

Catherine and Asami

If the bisexual preference is enabled, their shared scenes include:

#347: have them clean you.
#348: alternative clean-up arrangement.
#349: have them clean each other.

Helga

#351: drink her milk.
#352: finger her ass.
#353: anal.
#354: sleep plugged in.

Part 7 – Latest Progression and Choice Reference

Amelia and Asami

At the Garage:

#360: choose whether Amelia dominates Asami.

Polly Group Progression

#361: spank Polly.
#362: choose the pee party.

The pee-party variation requires the earlier watersports preferences involving Catherine and Asami.

Abraham

Later Abraham progression includes:

#364: sleep inside.
#365: use her mouth.
#366: anal.
#367: finish on her stomach.

Mabel and Megan

#368: finger her ass.
#369: fuck her ass.
#370: choose between creampie, anal creampie or filling all holes.

Shawna and Catherine Threesome

Shawna’s early route returns much later, which is why the opening choices matter.

#371: tell Catherine to eat out Shawna.
#372: tell Catherine to clean Shawna.
#373: pee in Catherine’s mouth together.

The bisexual portions require #092, while some variations also reference Shawna’s earlier relationship and sexual choices.

Shawna Anal Route

#374: rimjob.
#375: anal sex.
#376: have Catherine clean you.
#377: have Catherine clean Shawna.

GILF Orgy

#378 – GILF Orgy is one of the later multi-character event flags.

As with other large group scenes, earlier Relationship Points and sexual-preference decisions influence which variants are available.

Asami Advanced Route

#379: spank Asami.
#380: allow her to masturbate.
#383: have Asami clean you.

Annabelle and Sophia

The later shared route includes several explicit decision flags:

#384: have Annabelle eat Sophia’s ass.
#385: buttfuck Annabelle with a banana.
#386: let Sophia buttfuck Annabelle with the banana.
#387: feed Annabelle the butt banana.
#388: milk Annabelle.
#389: drink Annabelle’s milk.

The lactation variations require the earlier milk-play preference where indicated.

Sabrina and the Sisterhood

#390 – Induct Sabrina into the Sisterhood continues the Sisterhood storyline if that route has already been established.

Isabella and Catherine

#391: have Catherine clean Isabella.

This variation depends on the bisexual preference.

Debbie and Zelda

#393: anal sex during their later shared scene.

Genevieve and Josianne

Continue Genevieve’s positive introduction and maintain Josianne’s Relationship Points. Their later progression leads into shared content.

Yvonne

Yvonne has a particularly important route decision:

#397: reject her and remove her route.
Alternatively keep her route active and continue the sex scene.
#398: spank her.
#399: choke her.
#400: slap her.
#401: spit in her mouth.
#402: make her clean up.

If you want to preserve Yvonne content, do not select the explicit rejection route.

Catherine Butt Plug and Anal Route

#403: give Catherine a butt plug.
#404: rim Catherine.
#405: anal sex.

Mila Watching Route

#406: let Mila watch.
#407: choose whether Mila cleans you, leaves it dirty or does neither.
#408: choose rough entry.

Kayla

#409: eat Kayla’s ass.
#410: drink Kayla’s milk.
#411: finger Kayla’s ass.
#412: have Catherine clean you.

Amelia

#413: watch Amelia pee.
#414: clean Amelia.

Matilda

Matilda’s anal route requires earlier Betty progression:

Betty anal sex #320 must already be available.
#415: anal sex with Matilda.
#416: have Matilda clean you.

Jamila Advanced Route

#417: drink Jamila’s milk.
#418: anal sex.
#420: handjob on the bus.
#421: continue when the bus stops.
#422: drink Jamila’s milk during the store sequence.
#423: finger Jamila’s ass.

Lina

#424: spank-fuck Lina.
#425: pull her hair.
#426: double creampie.

Megan and Sandra

After progressing both routes:

#427: facefuck Megan.
#428: ass-eating train.
#429: anal sex.
#430: cover her in cum.

Asami and Catherine Watersports

The latest Asami/Catherine route continues to check the earlier watersports preference:

#431: pee in Asami’s butt.
#432: have Catherine drink the pee from Asami’s butt.

Svetlana and Catherine

If Svetlana has sufficient Relationship Points and #092 is active:

#433: have Catherine eat Svetlana.

Kayla and Abraham

#434: anal sex with Abraham.
#435: have Abraham clean you.

Fiona and Riona

The later return to the bar checks both Riona’s Relationship Points and the bisexual preference.

#436: have Fiona eat Riona.

Important Global Decisions to Remember

Decision	Effect
#011 – Sleep sex	Enables later scenes involving sleeping characters.
#023 – Okay tasting breast milk	Starts early lactation-related progression.
#032 – Watersports with Catherine	Used as a prerequisite for many later watersports scenes.
#033 – Elizabeth & Catherine together	Enables some shared Elizabeth/Catherine content.
#066 – Drinking Jamila’s breast milk	Important for Jamila’s extended lactation route.
#092 – Girls playing with each other	One of the most important requirements for bisexual, threesome and group-sex variants.

Relationship Points

Relationship Points are one of the most common prerequisites in Grandma’s House. If a walkthrough branch says a character must be at least 1, the corresponding relationship value must be positive before the scene can occur.

Important character variables include:

Character	Console Variable
Aaliyah	`aalPoints`
Abby	`abPoints`
Annabelle	`anaPoints`
Betty	`btyPoints`
Catherine	`cPoints`
Sandra	`copPoints`
Dean Nelson	`deanPoints`
Debbie	`debPoints`
Priya	`docPoints`
Elaine	`elaPoints`
Fiona	`fiPoints`
Genevieve	`genPoints`
Helga	`helgaPoints`
Imogene	`imoPoints`
Isabella	`isaPoints`
Jada	`jadaPoints`
Jamila	`jamPoints`
Jasmine	`jasPoints`
Josianne	`josPoints`
Kayla	`kayPoints`
Karen	`krnPoints`
Elizabeth	`lPoints`
Lily	`lilPoints`
Lina	`linaPoints`
Shizuka	`maidPoints`
Aiko	`massPoints`
Matilda	`matPoints`
Mabel	`mblPoints`
Mila	`milaPoints`
Minnie	`minPoints`
Natalia	`nbrPoints`
Allison	`nnPoints`
Ophelia	`ophPoints`
Paveena	`pavPoints`
Polly	`plyPoints`
Riona	`riPoints`
Sabrina	`sabPoints`

Sister Maria	`smarPoints`
Monica	`snPoints`
Sophia	`sophPoints`
Svetlana	`svtPoints`
Zahra	`szPoints`
Tanya	`tyaPoints`
Twins	`twnPoints`
Yvonne	`yvPoints`
Zelda	`zelPoints`

Cheat Without a Mod Walkthrough

The source walkthrough also explains how to modify Relationship Points and decision variables through the Ren’Py developer console. This is optional and is not required for normal gameplay.

The main reason to use the console is to test another branch without restarting the entire game.

Opening the Console

The walkthrough recommends enabling the developer console through a compatible Ren’Py console method. Once enabled, load a save and open the console using the configured console shortcut.

Change Relationship Points

The general syntax is:

characterVariable = value

For example:

aalPoints = 3 anaPoints = 2 cPoints = 3 jamPoints = 2 ophPoints = 2 shwPoints = 3

Typing the variable without assigning a value checks its current value:

aalPoints jamPoints shwPoints

Change Important Decision Flags

Decision flags usually use 1 for enabled and 0 for disabled.

Sleep Sex

sleepSex = 1

Disable:

sleepSex = 0

Watersports with Catherine

catWatersports = 1

Bisexual Content

bisexualEnabled = 1

This corresponds to the important #092 – like girls playing with each other choice.

Jamila Lactation

jamLactation = 1

Jamila Breastfeeding

jamBreastfeed = 1

Betty Anal Sex

day140bettyAnal = 1

Shawna Anal Sex

day151shawnaAnal = 1

Catherine Anal Sex

day154catAnal = 1

Latest Decision Variables

Some of the later walkthrough decisions use the following variables:

amyDomAsami = 1 day149pollySpank = 1 day149peeParty = 1 day150abbyAnal = 1 day150catCunniShawna = 1 day150catDoublePee = 1 day151shawnaRimjob = 1 day151shawnaAnal = 1 day151gilfOrgy = 1 day152milkingAnnabelle = 1 day152drinkMilk = 1 day153yvonneSpanked = 1 day153yvonneChoked = 1 day153yvonneSlapped = 1 day154catButtPlug = 1 day154catRimjob = 1 day154catAnal = 1 day154kaylaRimjob = 1 day155kaylaBreastfeed = 1 day155kaylaAssFingered = 1 day155matildaAnal = 1 day155jamilaAnal = 1 day156catPee = 1 day156jamilaHandjob = 1 day156jamilaHandjobContinue = 1 day156jamilaAssFingered = 1 day156linaSpankFuck = 1 day156linaPullHair = 1 day156linaDoubleCreampie = 1 day156meganFacefuck = 1 day156assTrain = 1 day156meganAnal = 1 day156meganBukkake = 1 day157asamiPee = 1 day157catDrinkAsami = 1 day157catEatSvetlana = 1 day157abbyAnal = 1 day157abbyClean = 1 day157fionaEatRiona = 1

These commands should mainly be used when you understand which route you are modifying. Forcing a late decision without its earlier prerequisites can produce a save state that does not match normal progression.

How to Get the Most Content in One Playthrough

If your goal is to unlock the largest possible amount of content without repeatedly restarting the game, the safest general strategy is:

Build positive Relationship Points with new characters whenever possible.
Avoid responses that explicitly reduce a character to 0 or -1 unless you intentionally want to reject that route.
Enable sleep sex if you want all sleeping-character variants.
Enable Catherine’s watersports route if you want later watersports content.
Accept Jamila’s lactation and breastfeeding routes if you want the later milk-play scenes.
Choose that you like girls playing with each other if you want the largest number of threesomes, lesbian scenes and group-sex variants.
Keep major characters such as Catherine, Elizabeth, Jamila, Asami, Annabelle, Ophelia, Sandra, Shawna, Fiona and Riona above 0 Relationship Points.
Pay attention whenever a choice is associated with a numbered decision flag because that choice may be checked much later.

Why a Scene May Be Missing

If you cannot trigger a scene shown in the walkthrough, check these conditions:

The required character may not have enough Relationship Points.
You may have rejected an earlier route.
The scene may require a specific decision flag.
Sleep sex may need to be enabled.
The bisexual-content flag may be required.
A watersports, lactation, anal, BDSM or other preference may need to have been established previously.
Another character involved in the scene may not have enough Relationship Points.
The scene may have an alternative version depending on an earlier decision.

Walkthrough Coverage

This guide combines all seven supplied Grandma’s House walkthrough PDFs into one searchable resource. The source walkthrough follows the game from its earliest content through the later storyline and records only decisions that can affect the story, character relationships or later scene availability.

The numbered decision system is intentionally preserved here because choices made near the beginning can still be referenced much later. Sexual terminology such as anal sex, blowjob, creampie, rimjob, threesome, watersports, breastfeeding and sleep sex is also retained where it represents an actual game choice or route condition.
