Living Together!

The Authentic Oniichan hentai experience where you live together with a person you affectionally call Imouto, and she refers to you as Oniichan  ─ Living Together!

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.

Game Mechanics (Implemented)

One-handed gaming ;)

Build Trust

Trust is the most critical aspect of this game. If she trusts you, she will be open to going further. Fail, and she might even decide to call Mom! Most of everything you do when you interact with her is also (co-)dependent on her trust in you. Even if she finds you highly sexually attractive, without trust, she will never dare to confess her feelings to you. The best way to build trust is to talk to her, do fun activities with her, and refrain from doing things she dislikes.

Build Attraction

She will only see you as a big brother or friend without attraction. With enough attraction to you, you may initiate sexual activities, and she won't reject you. Without lust for you, anything of a sexual nature will lead to a swift dismissal...and her losing her trust in you! Low trust, high attraction, and you're just a masturbatory fantasy for her. High trust, low lust, and you're friend-zoned. There is a middle ground you have to find. Building her desire for you can be done through flirting, talking about lewd topics and later by engaging in sexual activity that she finds pleasant.

Interest Matrix

She is modelled with a realistic, comprehensive psychological matrix that is randomised using a seed. This means her exact psychology and interests will differ from playthrough to playthrough! Seeded means it is neither completely random nor set in stone. Each of her over half a googol (10^100) of persona types is believable.

By interacting with her, you can discover her interests and even broaden or deepen her interests.

Discussion Topics

You can build trust by finding discussion topics that strike a chord with her, e.g., that are interesting to her. The higher the interest, the more trust you can build with her. You always get 1 Shared Interest that you can choose at the start of a game. You can find out other high-interest topics she likes by discussing with her regularly and on various topics. You get to discuss each topic once a day.

Story Events

You unlock Story Events, usually day or weekend trips, by building trust or attraction. These events can increase her trust, lust or mood for the better or the worse. By bonding with her during these events, you can increase her trust in you or desire for you. 

Lewd Topics

Sexual interest and attraction can be built by discussing lewd topics. She will naturally be interested in these topics as she's of that age. But, being completely inexperienced, she will take time warming up to discuss these topics openly with Oniichan. Her having high trust in you is paramount, especially when you take those first careful steps. 

Mood

Like everyone, Sister has emotions expressed in a general mood. This can be bad, normal, good, happy, embarrassed, etc. Unlike most modern women persons, Sister is well-adjusted, and generally, her mood is normal and stable. Even if she's on her period or not feeling well, her surface mood should be normal most of the time.

But anyone can have a bad day, and your actions can also sour her mood. Luckily, Oniichan can also try to lighten his little sister's mood with games or by cheering her up. Her mood will also influence the trust you can build up from other actions and how receptive she will be to sexual advances.

Menstrual Cycle

She has a menstrual cycle, going through 4 phases on a 21 to 25-day schedule. Her phase in the cycle will influence her mood and her sexual desire. It will also determine her chances of getting pregnant. Certain Oniichans can smell when she's on her period or ovulating. Other Oniichans can try to work out her schedule using the calendar in the room.

Customisable Oniichan

Choose your history with your little sister, each option giving you different advantages and disadvantages when you start a new game. Examples are knowing her favourite discussion topic, having higher trust or attraction, or even knowing when she's on her period.

Career path styles will influence how much money you have to spend and how much time you get to spend with Shiori in the evenings. A student will be home when she's home, giving you maximum exposure time every evening. A part-timer will be home later but has more disposable income to spend on his little sister.

Day - Night and Week Cycle

The game has a perpetual day/night and week cycle. During the days, you'll be at work or at school (or laze around in bed if you're a NEET!). You'll find yourself in her company at home during the evenings. That's when most of the interaction with her happens. Weekends work a little differently since you'll be together all day. That's also when you can enjoy each other's company outdoors and make happy memories together. These activities can cost money but are essential for bonding. 

Depending on the scope of the activity, this features a visual novel story with potential extras. PLANNED: specific weekend activities based on specific interests she may have or develop.

Energy Management

Every action costs energy, and you have a finite pool of energy (indicated by your smartwatch battery). You can also regenerate energy with relaxing activities like drinking tea, soda or bathing. Quality sleep at night is the best way to regenerate a chunk of energy.

Planned Game Mechanics

I want to include this in the game before I call the Alpha done. This list may change in the exact details or by adding/scrapping ideas altogether.

Night-time wholesome and lewd interaction (a major part of the game!)Nude bathing together with wholesome and lewd interaction (a major part of the game!)Additional weekend outdoor activities (an important part of the game).Weekend activities are based on her interests (long-term wishes).Good and Bad Endings: when she gets pregnant by you, the game ends, and there will be good and bad endings. Good endings involve high trust and having enough resources to make it work. New Game+ (either continue after an ending or indeed start over with some inherited benefits)
