Presets are also available, allowing you to enjoy diverse play with a single click right after purchase.
Other characters’ save data can also be loaded. The part-load function, which allows loading only a portion of the save data, makes it easy to create a vast number of combinations.
There are 26 basic positions available. Natural motion through physics calculations allows you to choose from five types of hip movements besides pistoning, and you can finely adjust the speed and movement size. By making slight adjustments to the hip position, you can enjoy changes in motion.
You can finely set and save & load your preferred facial expressions. It is also possible to create and continuously play facial expression sets.
You can adjust the size and softness of the breasts, and interact with them using mouse controls.
You can finely adjust the neck angle and gaze. With the left and right neck movement function and random function, you can add natural accents to the movements.
Clothes can be freely put on and taken off, and you can adjust the hair color, tanning level, and tongue color.
The camera can shoot freely from any angle and distance within 360 degrees. Post-processing allows you to capture images with a three-dimensional feel by blurring the background.
You can perform a five-point simultaneous attack by inserting into the vagina and anus while vibrating the rotor and interacting with both nipples.
Enjoy playing in various scenes such as bedrooms, bathrooms, courtesan rooms, classrooms, infirmaries, and hot springs.
You can freely orgasm at any timing with the timer and one-touch operation. By adjusting the expressions and the frequency and intensity of convulsions, you can control the behavior during orgasm.
You can adjust the color, brightness, and position of the lights.
You can choose from five voice actors and adjust the pitch and sound effects.
If your display and hardware support it, you can enjoy smooth behavior at up to 120FPS. The display supports any ratio, including portrait and landscape.
* Precautions
Depending on the combination of parameters, there may be cases where the character’s behavior becomes unnatural. Please understand this in advance.
* System Requirements
This software is for Windows only.
The required machine specifications vary depending on the screen resolution and target FPS, but if it is around Full HD 60FPS, you can enjoy it comfortably with an entry-level GPU. Please check the trial version for operation.

Editorial Review
3D sex simulators occupy a peculiar space in the adult doujin market—technically accessible tools rather than narrative-driven experiences, yet increasingly sophisticated in their physics engines and character customization. This entry sits firmly in that simulation-focused category, positioning itself as a physics-driven playground rather than a story-based work.
The standout feature here is the parametric customization system. With over 100 adjustable parameters, the save-and-load architecture transforms what could be a static simulator into something closer to a modular composition tool. That part-load function—allowing users to mix and match saved configurations—is genuinely useful for generating variety without starting from zero each time. Twenty-six base positions across six characters suggests breadth, though without detail on their distinction or animation quality, it’s difficult to assess whether variety translates to replayability or mere numerical padding. The dual approach of preset configurations for quick gratification and deep customization for tinkerers addresses two different user types effectively.
The inclusion of voice and animation alongside the 3D models hints at production effort beyond bare-bones asset recycling, though the synopsis frustratingly cuts off mid-sentence, leaving questions about animation fidelity and voice acting scope unanswered. The bilingual support (Japanese and English) widens accessibility in an otherwise niche segment.
This appeals specifically to players who view adult content as interactive parameter exploration rather than passive consumption—users drawn to spreadsheet aesthetics and creative control over raw mechanical systems. Casual players seeking linear, story-inflected experiences will find this approach sterile and uninviting.
A competent tool for customization-focused enthusiasts willing to invest time in its parametric depth, though depth without transparent information about animation quality and character distinctiveness remains a calculated gamble.
