Overview

Meet your love interest (nameable). She’s referred to you all her life as Oniichan (relationship changeable). Affectionately, you also call her your little Sister (also changeable)!

You cohabitate in a small studio apartment. You’ll have to get along in this small area where you’ll spend a lot of time together. Through interacting with her, you build up a relationship that’s based on trust, friendship . . . and more! Talk to her and find out her favourite topics, play video games, and take her with you on day trips. Through your actions, she can come to trust you more, and, of course, you can also build her sexual attraction toward you. But be warned! You can also lose her trust in you.
Living Together! is a laid-back game intended to be played with one hand. Please enjoy this simple Oniichan game.​

Changelog

v0.60

• Added a Pregnancy Endingsequence where she confronts you with the “positive” results:
  • You are ‘tested’ from her point of view and she will make a decision whether to stay or leave.
  • There are 4 tests (mate potential, her ambitions, home stability and economic viability) and you must pass all of them for her to stay.
  • Failing even one of the tests will mean she leaves, resulting in a bad ending.
  • The tests include the following minimums: 400 Trust, 300 Attraction, 180 days living together
  • The other factors are weighted, so there is no one formula that passes the tests
  • Hedonistic and Nihilistic Oniichans (Restaurant date) cannot see themselves taking the role of a father and will always fail the test.
• Added “Good Ending 1: An Expecting Couple”
• Added 4 Bad Endingsif you chicken out after a pregnancy confrontation and make the decision for her.
  • These are seriously bad endings and not lighthearted at all. Will monitor player reaction to these.
• Added a Pregnancy Epilogue of circa 150 days:
  • Epilogue starts a few weeks after the confirmation.
  • You can spend around 150 days together until the baby is born
  • The birth date is not set in stone but will happen between 2 weeks before and 1 week after the 150 day expectancy.
  • Added pregnant evening interaction
  • Added pregnant epilogue day job for weekdays
  • Added bathing routine for the pregnant epilogue with washing and sex scenes
• Fixed small graphical errors in bathroom scenes
• Fixed a small error in the trust and attraction gain curve around level 6
• Fixed an issue with “story mode” staying active after you have sex with her while cooking dinner
• Having vaginal intercourse in the bathroom now also tallies towards the total times she had vaginal intercourse.
• Removed various leftover code from previous patches that made using previous version saves work for the current update. All these have now been removed and cleaned up. This means that very old saves (a couple of patches old) will not work correctly on 0.60 and above.

v0.60b (patch)

• Fixed the game going to the pregnancy epilogue when playing a game in the weekend or vice versa, the game exiting the pregnancy epilogue back to the normal game mode when doing the same.
• Fixed error “ScriptError: could not find label ‘running_commentary_day’.” when visiting the grocery store during week days.

v0.55

• Added Anal Sex at night (unlocked along with vaginal sex):
  • From the “From Behind” position
  • Requires 30ml of lube
  • You can buy lube at the pharmacy in the shopping mall.
• You can now have vaginal sex with her when she’s cooking dinner.
• Having sex with her in the pool now correctly takes 1 nut charge.
• Minor bug fixes

v0.54

• You can now revisit the swimming pool after unlocking vaginal sex for an optional, animated sex scene in the crowded pool (Public sex fetish)
• You can now set the difficulty mode as part of the new game setup.
• You can now have intercourse more than once a night if you still have loads left.
• Fixed drinks sometimes not giving energy (happened if your current energy was exactly as much below maximum energy as the drink added).
• Fixed error “Image “character_interaction_screen_weekend” not found”, when she leaves for her part-time job on Sunday.
• You can now exit out of the transfer funds screen in the Big Brother Bank App without needing to transfer money.
• The Fighting Game is now available through the DAMPF App.
• Fixed Dr. Poppers having a 100% chance of making her pee.
• Various typos in recent additions/events fixed.
• The night-time smartwatch now shows up like it should when going into the night scene after nutflex
• Fixed if she rejected you at night because she is menstruating, the speech bubble would stick permanently.
• Possible fix for “TypeError: type str doesn’t define round method in new_day_behavior.rpy” in around line 700-1200 (776 in 0.50).
• Coming back from the Emergency Prescription Service now changes the background back to the house.
• Mom’s call now correctly states she will be working on Sunday, not Saturday.

v0.53

• Orgasm from vaginal intercourse: She can now reach orgasm from Missionary vaginal sex if she starts masturbating. She won’t always do this, and it’s up to her to do. She will also only masturbate if you start and keep up with slow thrusts; going too fast will make her stop.
• Bathroom Vaginal Sex: you can now have vaginal intercourse with her in the shower room, after you have washed her front.
• Emergency Anti-Conception:you can now order a morning-after pill through your Phone Browser using the Emergency Prescription Service. You can order 1 pill every 30 days, and it has an 80% chance of preventing pregnancy. It does not work if a fertilised egg is already implanted (after 4 days).
  • If you are using a pre-0.53 save, allow 1 day to pass before using the Emergency Prescription Service (see location tracker).
• Nighttime missionary sex animation timings slightly tuned for going slower.
• She likes slower thrusts during intercourse, which makes her arousal go up (important if she wants to cum from vaginal)
• Internal: “current location” tracker. The game now has a location tracker that stores where you are (day, evening, weekday, weekend) and uses this to send you back and forth to outside locations. For instance, going to the Emergency Prescription Service, the game now knows where to send you back where you started. This is a new, internal feature. Expect bugs.

v0.52b (patch)

• Fixed error while choosing to stay inside at night after doggy style.
• Temporary fix for error during evening bj because of a missing animation frame. The frame has been taken out of the sequence for now, and will be added in the next content update.

v0.52

• New Weekend Activity: LARP Event: an optional light fetish event in the form of a fantastical short story for you to enjoy. Unlock it by first doing the Ryokan event and having played the weekend board game at least twice.
  • The number of times you played a board game is a new variable, so it only starts counting with the new update on old saves. Something to work for.
• Added short 3-frame cut-in section for the weekend board game activity.
  • Playing the board game with her at least twice is one of the unlock requirements for the new LARP event.
• added experimental “sunglasses” toggle overlay for flashing animations, reducing glare by ~50%.
• Slightly increased pull-out timer before you cum inside her, both normally and when she encourages you. This makes it easier to pull out in time.
• Fixed error while choosing to stay inside at night after doggy style.
• Temporary fix for error during evening bj because of a missing animation frame. The frame has been taken out of the sequence for now, and will be added in the next content update.

v0.51

• Vaginal Sex: Cowgirl. You can now let her ride you. If she is particularly horny and ovulating, you might have to beat the pull-out timer twice (or just let it happen).
• Vaginal Sex: Doggy. You can now have sex with her from behind. You have more control (longer pull-out timer) while thrusting faster in general.
• Live Inseminations overhaul: live inseminations now exist each as separate entities, each with a 3-day lifespan inside of Imouto’s vagina. Each insemination that is still alive contributes to her conception chance based on that insemination’s age and Imouto’s fertility. This is a more comprehensive approach than being a simple factor in a single equation result being rolled against. The chances/risks of her getting pregnant are practically the same as the original intent.
• Night time vaginal sex now has the same requirements as the Ryokan event in 0.50b (250 Trust & 200 Attraction).
• Imouto will now get more aroused during penetrative sex (wetter) up until orgasm is close. Just like with fingering, starting slow at first and going rougher once she’s worked up is the best way. She will still need either oral or digital masturbation to push her over the edge (future updates will have her masturbate herself while you’re thrusting).
• Contextual wake-up remark: Imouto may now plead for vaginal sex when she wakes up at night, if she’s horny enough.
• Imouto may now strongly encourage you to ejaculate inside of her when she’s ovulating and if she’s aroused enough. Her remarks will speed up the pull-out timer.
• Imouto’s Part-Time Job moved to Sunday to allow for the Ryokan visit.
• Fixed a UI issue where her Menstrual Cycle would be included in the SISTER app regardless of Oniichan type.
• Fixed small continuity error that made it possible to ejaculate raw while wearing a condom from one moment to the next.
• Added memory predictions to night time intercourse animations, pre-loading them into RAM just before the scene is entered. This should make loading the scene after choosing a sex position slightly longer but make the transitions between animations faster.
• You can now stop fingering her in the bathroom before she reaches orgasm.
• Small bug fix where her hygiene level would progress past 100%.
• Fixed grey screen frame when visiting Hanami after the first time.
• Fixed some transition issues between Nutflex & Chill and the nighttime sex scene.
• Fixed bug where visiting Hanami for the second time would load the evening scene even if it was still morning or afternoon.
• Fixed error “character_solo_masturbated” when peeking on her on the toilet masturbating.

v0.50
DEV NOTE: SAVE OFTEN! Pregnancy mechanics is very experimental.

• New Weekend Activity: Ryokan. Take Imouto to the onsen inn where you make love to her for the first time.
• New Night Time Lewd Activity: Missionary Vaginal Intercourse. She needs to be wet before you can penetrate her.
  • You can have intercourse with and without a condom. Doing it raw gives you the option to pull out, with a short timer to do so once you know you’re going to cum.
• Added a Difficulty Levelselector in the Options screen with a Normal and an Easy option:
  • The new Easy mode prevents many of the trust and attraction loss events from happening, such as negative conversation outcomes, not having food, or getting caught peeking. Easy Mode also grants the Player a 5000 Yen Universal Basic Income. This turns the game almost into an AVN with a few extra clicks to chat with her.
  • Normal mode is the same as the last balance overhaul in 0.45. Per May ’25 statistics, most players succeed in unlocking all content in 2~4 hours in Normal mode.
  • I hope this resolves the need for people to install 3rd-party “QoL” mods and then blame me for the issues they cause.
• All Options are now available in the in-game Phone options app the same as the main menu options.
• Options Menu now has a tooltip for some of the options to explain what they do.
• Condoms now serve a function in preventing pregnancy during vaginal intercourse.
• You can now stop fingering or licking Imouto at night before she orgasms.
• Fixed an issue where the speech bubble would remain after being rejected by Imouto at night.
• Revised Budgeting window in the Big Brother Bank app correctly shows the cost of Liabilities, and with a clearer layout.
• Revised Psychosomatics section layout in the S.I.S.T.E.R. app.
• Updated Imouto’s fertility to its “initial final” iteration for the release of vaginal sex. It now reflects realistic conception chances.
• S.I.S.T.E.R. app’s Sexual Activity “Conception Chance” window updated to show Imouto’s fertility in % instead of giving the complicated internal formulas.
• Updated the Save/Load screen layout and background for much better readability. This ends the running meme of the whole UI looking sleek, except the saving/loading.
• Added a split second fade/black frame between switching views for night time lewd activities. This prevents ‘ghost images’ from appearing for a glimpse.

Modding / Translation Support

• The game now detects language folders in the “/tl” folder and adds them to the in-game options Language selector
• Added Font: Noto Sans Simplified Chinese
• Added Font: Noto Sans Mono for community translations in Cyrillic, Greek and Devanagari
• Added Font: Noto Sans Thai
• Added Font: Noto Sans Japanese (Kanji, Hiragana and Katakana)
• Added Font: Noto Sans Korean
• Added Font: Noto Sans Arabic

  • Requires you to finger Imouto 5x prior and have 200 Trust and 160 Attraction.
  • Costs 1200 Yen
  • Unlocks blowjobs.
  • There is a very high chance that you will discover an undiscovered Lewd Interest Topic during this activity.
  • Going to Hanami will calm Imouto and prevent a bad mood from naturally occurring for 3 days (you can still ruin it yourself, though).
• Added a hint that certain buttons in the smartphone open your browser to an external link (substar, x/twitter and adventgames).
• Balance: All first-time Weekend Activities except jogging can now raise a Bad Mood as well (to Normal).
• Balance: All repeat Weekend Activities except jogging will now improve Imouto’s mood by 1 level.
• Narrator update about discovering a High Interest Topic should now only appear once, upon first discovery.
• Small UI improvements to Grocery Store layout
• Possible fix for a second Imouto appearing in front / behind her and Imouto while bathing or fingering her.
• She should now be willing to bathe together more consistently.
• She should now only be ready for fingering after NutFlex & Chill
• Alcohol (being drunk) can no longer goad her into penetrative or masturbatory sex before it is unlocked (to avoid internal code conflicts).
• Weekend Activity Requirements:
  • Karaoke now requires 80 Trust and 80 Attraction.
  • NutFlex & Chill now requires 120 Trust and 120 Attraction.
• Small increase in music volume for Night Time Lewd Activity track.
• Waking Imouto up at night while she’s on her period will no longer result in an instant rejection, but a warning she doens’t want to that night. It’s best to go to sleep.
• Imouto will reject NutFlex & Chill if she’s on her period.
• Fixed bug where you technically couldn’t go to sleep after waking Imouto up during the night (would only happen at a point in the game where she’d reject you anyway).

v0.43c

Fixed: infinite loop cycling through the fingering scene at night.

HODL App: “Available Balance” renamed to “Limit”

HODL App: All Options are now leveraged at 400% using other people’s money. You lose only the price change or up to your investment. But, you win the price change times 3 if you guessed correctly. These “other people” have their money in what they think is a mutual fund, but HODL is using it for decentralised Options trading using you and many others like you. Some say the real leverage is 450% and HODL skims off the remaining 50%.

Day Traders: New Game Checkings Account Balance increases by ~300%. You start with large amount of capital from getting lucky before. Trade Options wisely with it now.

Day Traders New Game Savings Account will now be 0 as they need everything for their trading.

Going on a picnic after the first time will now correctly add 15 Trust.

Christmas Special (Weekend Activity when you play between December 15 and December 31st)

Fingering mechanic disabled. It is now an animated event.

Several animation timing touchups to night-time fingering

Tweaked and added Imouto exclamations during fingering.
