Companion Mode is finally avaliable for all Patreons to play and test!
What is Companion Mode?
What is Companion Mode?
Think of Companion Mode as adaptive gameplay that grows with you. It is designed to be a highly responsive, personalized experience where your partner actively observes your rhythm, learns what you like, and anticipates your needs.
Getting Started
If it’s your first time diving into Companion Mode, we recommend exploring the customization options first by clicking the disk icon in the top left. You have absolute control over your experience from start to finish.
- On-the-Fly Adjustments: Most settings—including stage durations, arousal levels, and poses—can be adjusted in real-time using the interactive in-game handles and UI.
- Deep Customization: For advanced fine-tuning or to manage your session presets, you can open the full Companion Settings menu at any time.
The Adaptive “Brain”
Companion Mode is powered by a system that actively learns your playstyle to deliver a seamless experience.
- Smart Pacing: The game tracks your time to climax. If your pacing consistently changes, the engine naturally adapts the session to match your rhythm.
- Dynamic Speed: When you manually adjust stroke speed during gameplay, the system takes notes. It gradually learns your preferred intensity for every single stage. Over time, each part of the encounter will automatically default to the exact speeds that fit your playstyle.
Session Stages
Every session flows through five distinct phases: Warmup, Buildup, Main Course, Almost There, and Climax.
- Duration Control: Your global “Time to Orgasm” setting dictates the base length of each stage.
- Progress Tracking: Meters at the bottom of the screen show your real-time progress toward the next phase.
- Manual Overrides: Use the in-game handles to tweak stage durations on the fly, or use the arousal slider to scrub forward and backward through a stage’s progress.
- Coming Soon: Currently, your partner’s arousal directly mirrors your own.
In future updates, she will develop her own independent internal experience.
Poses & Progression
You dictate the action. Using the in-game menu, you can whitelist specific poses for each stage or instantly trigger a pose change.
- Seamless Transitions: When it’s time to move to the next stage, she will ask if you are ready. You can choose to advance or simply say, “Not Yet.” If you decide to linger, the system automatically recalibrates your session timing to account for the extra time spent in that stage.
- Triggering the Finale: Advancing to the final “Climaxing” stage is entirely in your hands. You must manually press the “I’m Cumming!” button or trigger it via voice command.
Voice Control
When Voice Control is enabled, you can communicate directly with your partner. She listens, interprets, and reacts to your spoken cues to adjust her speed and movement.

[ Customization Improvements ]The character customization system has been optimized to reduce slowdown during customization to almost zero across most system hardware configurations – In preparation for the new game mode, we’ve added seamless equipping and removal of clothing items during gameplay. In addition, poses will automatically remove any clothing that is blocking entry for sex, and then put them back on when done.

Added one-piece crotchless lingerie/swimsuit in three patterns.
[ New Poses ]Added missionary legs spread
Added anal variant of Missionary
Added anal variants of Lean on Wall poses [ Mod Support (WIP) ]Stripped Odin dependencies from OhBits and all related assets in preparation for custom story and game mode modding.

This is really important, as this would’ve made it impossible to release a full modding option for people down the line.

– Crystal ball image search should now be working again (We had to completely re-make the backend for this to work again
– Character models should no longer disappear when changing poses
– Breast physics should now properly follow different sized breasts

Please keep in mind that this is merely a sample of what we want the full JOI experience to feel like, and it is by no means a representation of the complete Lustbound game experience.
We plan to explore many more ideas outside of JOI.
For now you’ll get to experience the basic red light / green light gameplay, along with dialogue interactions, Bluetooth sex toy integration and a handful of sex positions.
“But what if I don’t like JOI and that kind of gameplay at all?”
Well…First off, please let us know in the discord feedback channel what exactly you didn’t like. We take feedback to heart, and it can help us focus on making something you all enjoy!
Otherwise, look forward to the upcoming updates. We’ve already heard from many of you that Freeplay mode is important to you, so that is something we’ll be focusing on as well!
≔――――――――――――――≕
A detailed breakdown of what there is to experience in this JOI demo
