Key Findings
- Condition A (drooling) produced the most consistent “dripping saliva” effect – all 3 samples showed thin strands of saliva dripping from the mouth
- Condition B (saliva string) resulted in tongue-out expressions with saliva, and a wider mouth opening – tongue exposure was present in all 3 samples despite not being the primary descriptor
- Condition C (tongue out + ahegao) made the tongue the dominant feature, with saliva as secondary – ahegao drove the overall facial expression toward ecstasy, reducing the drool focus
- For maximizing saliva volume, use Condition A. For tongue-saliva combos, use Condition B. For overall expression breakdown (ecstasy), use Condition C

Base Prompt
Base Prompt
1girl, 32yo japanese actress, {EXPRESSION}, on all fours on bed, looking at viewer, black lingerie, indoor bedroom, soft lighting
The pose is fixed to all-fours on a bed with eye contact to isolate mouth expression differences. Outfit is black lingerie throughout.
Condition A: drooling
Condition A
drooling, saliva dripping from mouth, parted lips

Observations
- All 3 samples show thin strands of saliva dripping downward from the mouth
- Parted lips was consistently reflected – the mouth stays slightly open
- Tongue is barely visible; the drool flows naturally from the gap between the lips
- The expression has an unintentionally alluring quality with upturned eyes
- The saliva strands are thin and long, following gravity realistically
Condition B: saliva string
Condition B
saliva string between lips, open mouth, tongue visible

Observations
- All 3 samples show significant tongue exposure with an open mouth
- Despite “saliva string between lips” being specified, the output leaned more toward saliva dripping from the tongue rather than strings between the lips
- Mouth opening is noticeably larger than Condition A
- The tongue visible tag reliably produced tongue exposure
- Saliva volume is comparable to Condition A, but the visible tongue adds a stronger fetish dimension
Condition C: tongue out + ahegao
Condition C
tongue out, dripping saliva from tongue, ahegao

Observations
- All 3 samples show the tongue extended significantly
- The ahegao tag drives the mouth to open as wide as possible with an ecstatic expression
- Saliva is present but minimal – just small amounts dripping from the tongue tip or mouth corners, far less than Condition A
- The overall facial expression breakdown is the most dramatic, including the eyes
- Tongue rendering is consistent across all 3 samples, showing high reproducibility for tongue out
Cross-Condition Comparison
| Aspect | Condition A (drooling) | Condition B (saliva string) | Condition C (tongue out + ahegao) |
|---|---|---|---|
| Saliva Volume | High (long strands) | Medium (dripping from tongue) | Low (small amount from tongue tip) |
| Saliva Shape | Thin strands | Strands to droplets | Droplets |
| Mouth Opening | Small (parted lips) | Large (open mouth) | Maximum (ahegao) |
| Tongue Exposure | Minimal | Present | Fully extended |
| Expression Breakdown | Minor | Moderate | Major |
| Fetish Direction | Defenselessness, carelessness | Tongue-saliva combination | Ecstasy, pleasure |
| Reproducibility | 3/3 stable | 3/3 stable | 3/3 stable |
All three conditions show high reproducibility and function as saliva/drooling expressions. However, the direction of the expression differs significantly, so choosing the right one depends on your intent.
Note: Drooling works as a subtle expression achieved with just slightly parted lips. Saliva string is a more direct expression involving visible tongue exposure. Ahegao is primarily about the overall collapse of the facial expression, with the saliva effect appearing as a secondary accompaniment.
