Synopsis
A smoothly-animated Live2D onahole simulator about jamming a massive dick inside a certain strong-willed tengu lady.
Yes, show that thunder birb who’s boss, and delight in her lusciously animated reactions in real time.
The penetration controls make it feel like it’s you that’s dolling out the divine dick punishment!
Her movements, breaths are fully synced with the sound effects for an ultra realistic experience.
This simulation has no cheap machine-generated loops; it’s all been hand-tuned for maximum ERO.
* Have a look at the trial version if you’re not convinced!
Customization? How does ball gags, blindfolds, piercings, squirt intensity, body-scribbling, dick-size/intensity, hair color, skin color, breast size, and clit size sound? There are approximately 50 customizable parts in total!
Click and drag to control…
– Head
– Body
– Ass
– Breast
– Male performer
Fiddle around with her body, see how she moves, and you might just find a new favorite position!
[Emotion Engine!]
The heroine’s expressions change naturally depending on 3 parameters: Pleasure, Pain, and Stimulation.
Sudden intense movements can ramp up the pain if you want to play it that way, but the choice is yours.
Check the top left corner to check these parameters:
Yellow: Stimulation
Heart: Pleasure
Red: Pain
If you’re having trouble controlling the parameters, a setting is included for displaying the Emotion Graph,
which makes it easier to understand the exact effects of intensity, etc.
Of course, it’s great fun fiddling with her body, but this time, things have been taken up a notch with the multi-recording function!
Record your specific motions for each part, and combine them to easily create your own original animation!
[Trial Version]
You can verify your system compatibility via the trial version.
The specs are a bit high due to the real-time processing going on.
Sometimes running on Android will cause an insufficient memory error.
The trial version is missing some setting options.

Editorial Review
NejicomiSimulator Vol.4 occupies a distinct niche within the onahole simulator space—specifically, the high-fidelity Live2D segment where animation quality and mechanical interactivity are primary draws over narrative. It’s a category that’s seen significant refinement in the past few years, with developers increasingly competing on smoothness of animation and granularity of control rather than plot depth.
What distinguishes this entry is its emphasis on hand-tuned responsiveness rather than algorithmic shortcuts. The developers explicitly reject loop-based animation in favor of real-time synchronization between penetration depth, character audio, breathing patterns, and visual feedback. The tengu character’s expression of defiance-turned-surrender—suggested by the “strong-willed” framing and the “divine dick punishment” premise—appears designed to create a power-dynamic fantasy with visible character arc, even within a mechanics-focused simulator. The inclusion of roughly fifty discrete customization parameters (body dimensions, accessories, visual modifications) suggests this is built for users who want sustained replay value through configuration variation rather than a single “perfect” scenario.
The multilingual support (Japanese, English, Chinese Simplified) with APK inclusion indicates serious production infrastructure, while the trial version availability reflects confidence in the core mechanics.
This will resonate most with players who prioritize animation fluidity, tactile control feedback, and visual customization depth over character writing or extended scenario variety. The physics-simulation approach and emphasis on synchronized audio cues suggest it’s engineered for immersion rather than novelty.
For onahole simulator enthusiasts seeking hand-crafted animation quality and robust mechanical control options without compromise on repetition, this delivers technical competency in its category. Casual genre explorers may find the mechanics-first design alienating, but the trial version efficiently filters audience fit.
