Can't Stop Shaking! | H3 Ending Reaction Booster

Motion Booster handles the process, this LoRA handles the ending — well... one kind of ending. 😏

There are, apparently, quite a few ways to lose control. We’ll get to the others later.

Experimental Preview

Think of this release as a proof-of-concept first.

It is an early experimental version made to confirm that this effect can be achieved in a usable way.

If you test it, please post your results! Different characters, prompts, scenes, and workflows can reveal strengths and problems that I may never see in my own tests.

More feedback and showcase posts = a better improved version later. ❤️

What this LoRA does:

• Triggers strong residual orgasmic trembling

• Focuses on high-frequency, low-amplitude shaking in the thighs, knees, hips and lower belly

• Adds natural full-body responses: arched back, head thrown back, curling inward

• Creates fucked-silly, eyes-rolled-up, completely lost facial expressions

• Supports soft muffled moans, broken whimpers, and heavy irregular breathing

The key idea is strong intensity without exaggerated movement amplitude.

This means it works best for:

• dense fine pulses

• involuntary low-amplitude trembling

• repeated aftershocks

• full-body reaction driven by lower-body trembling

rather than:

• huge leg swings

• violent full-body thrashing

• exaggerated convulsions

How to Use

This LoRA works best as an ending-shot LoRA, not as the main motion generator for the full sequence.

Best workflow idea:

Motion Booster
→ handles the process, rhythm, movement, speed, and continuous action

Ending Reaction Booster
→ handles the stop, separation, and lingering reaction afterward

In other words:

• Motion Booster = the process

• Ending Reaction Booster = the aftermath

Trigger Words

endbody1

Controls the physical reaction.

endface1

Controls the facial reaction.

You can also use both together.

Compatibility

Recommended LoRA weight: 0.85

This version is designed and tested mainly for:

FL2VA

Recommended

REF2VA

Not recommended for this version

I tested it with REF2VA, but the results were noticeably less stable and less convincing than FL2VA.

A separate version specifically made for REF2VA is planned for later.

Consistency Tip

If character consistency starts to drop, try simplifying the facial-expression description and lowering the LoRA weight slightly.

Detailed facial reactions can sometimes compete with identity preservation, especially when using endface1. If needed, reduce facial detail first, then lower the weight.

Training note: This version was mainly trained on cowgirl, missionary, and doggy style. However, the trembling reactions and facial expressions are general and can work with other positions.

Important note: This LoRA was not specifically trained on genitals. For better pussy/cock detail, it is recommended to use it together with other genital detail LoRAs.

How to use it properly:

1. Let the man stop and leave the frame first

2. Then describe her residual reaction

3. Keep the trembling dense and fine — not wild thrashing

4. Combine the shaking with arched back / head tilt / body curling

5. Write her face as overwhelmed by pleasure, not pain

A small tip for anyone training H3 LoRAs:
Let aesthetics define the goal; let engineering validate it.
Action is the process; reaction is what gives it texture.
