This page is an English translation, produced with ChatGPT, of an article I previously wrote about how to generate NSFW illustrations using Stable Diffusion. I apologize if the wording sounds awkward.
If you’re uncomfortable with NSFW (sexual) content, please skip this article.
This article summarizes how to generate erotic illustrations using Stable Diffusion XL on ConoHa AI Canvas.

Overview of the Generation Process
- Generate a base image using t2i (text-to-image).
- Refine it using i2i (image-to-image).
Originally, I wanted to provide a universal prompt template, but in practice prompts are constantly adjusted while generating images, so here I’ll just outline the common structure.
t2i Prompt Sample
[Prompt]
1girl, explicit, newest, very aesthetic,
Concept (keep short),
character, pose, etc.,
looking at viewer, white background,
masterpiece, best quality, absurdres,
numbered,
[Negative Prompt]
worst quality, bad quality
Steps: 20
Sampler: Euler a
Schedule type: Automatic
CFG scale: 7
Size: 1050×1400
Model: waiNSFWIllustrious_v140
Replace 1girl with your desired number of characters.
For explicit scenes, removing looking at viewer may produce better results.
At this stage, keep negative prompts minimal so the model can interpret prompts more freely. Also, avoiding detailed body specifications early on often gives better results.
I use 1050×1400 or 1400×1050 to match my iPad screen ratio, but adjust as you like.
The highlighted parts will later be reused in the i2i prompt.
i2i Prompt Template
[Prompt]
1girl, explicit, newest, very aesthetic,
Concept (keep short),
character, pose, etc.,
looking at viewer, white background,
masterpiece, best quality, absurdres,
curvy, huge breasts,smile, blush, sweat, pussy juice, ass visible through thighs, navel, grin,
<Lora>
[Negative Prompt]
worst quality, bad quality, sketch, comic, (monochrome, empty eyes:0.5),
Steps: 20
Sampler: Euler a
Schedule type: Automatic
CFG scale: 7
Size: 1050×1400
Model: waiNSFWIllustrious_v140
Denoising strength: 0.85,
Add preferred body features below the copied t2i portion.
blush and sweat are versatile additions.
Add LoRA models at the end if used.
Add unwanted elements to the negative prompt as needed.
Typical denoising strength adjustments:
0.90 if too much unwanted detail remains
0.80–0.75 if poses change too much
Sample Generation
This time the example uses a reverse bunny suit with an erotic squat pose (actual output uncensored).
The article then walks through how this image was created. Detailed UI instructions are skipped; beginners should consult earlier guides.
Model Used
WAI-NSFW-illustrious-SDXL – v14.0 | Illustrious Checkpoint | Civitai
Use the latest version available.
Initial Settings
Euler a is recommended for this model.
Hires fix is not used here.
Generating with t2i
A base image is generated with t2i using the sample prompt, then refined via i2i.
[Prompt]
1girl, explicit, newest, very aesthetic,
reverse bunnysuit, squatting,
gyaru, presenting pussy, v over eye, rabbit ears, cleft of venus, bowtie, ribbon, nipples,
looking at viewer, white background,
masterpiece, best quality, absurdres,
numbered,
[Negative prompt]
worst quality, bad quality
Steps: 20
Sampler: Euler a
Schedule type: Automatic
CFG scale: 7
Size: 1050×1400
Model: waiNSFWIllustrious_v140
Seed values are omitted. The generated image (edited for display) is then used for the next step.
Refining with i2i
Move to the img2img tab, set:
- Sampling: Euler a
- Denoising: 0.85
- Image size identical to original
Drag the generated image into the input field and apply the i2i prompt.
[Prompt]
1girl, explicit, newest, very aesthetic,
reverse bunnysuit, squatting,
gyaru, presenting pussy, v over eye, rabbit ears, cleft of venus, bowtie, ribbon, nipples,
looking at viewer, white background,
masterpiece, best quality, absurdres,
curvy, huge breasts,smile, blush, sweat, pussy juice, ass visible through thighs, navel, grin,
[Negative prompt]
worst quality, bad quality, sketch, comic, (monochrome, empty eyes:0.5), piercing
Steps: 20
Sampler: Euler a
Schedule type: Automatic
CFG scale: 7
Size: 1050×1400
Model: waiNSFWIllustrious_v140
Denoising strength: 0.85
Because “gyaru” often produces piercings, piercing is added to the negative prompt.
The final output reflects the added prompt details, improving skin shading and overall quality.
Think of t2i as making a draft and i2i as refining details. This method often yields better quality and finer control.
Additional Tips
Character Style
Changing gyaru to jirai kei changes the character vibe. You can apply prompts for existing characters similarly.
Changing Character Count
Changing 1girl to 2girls with style tags allows decent separation of characters in current models.
For Sex Scenes
Add prompts like:
sex, position, 1boy, penis
Landscape images can work better for these scenes.
Finding Prompts
For models trained on Danbooru tags, Danbooru tag search is extremely useful for both NSFW and safe images.
