Seems like the site has some great models under the hood. I tried hard to recreate it, only to fail repeatedly. That said, I had problems making it do what I want.

In case you want to try, the prompts are: First one:

{
  "seed": 2139636250,
  "prompt": "complex 3d render ultra detailed, 1girl, (PureErosFace_V1:0.6), 20 yo, ((beautiful Korean naked woman, full body, pussy centered in image, pussy exposed)), (sharp focus on pussy and breasts), perfect face, perfect hands, sitting, looking at viewer, front view, real human skin, vibrant details, hyperrealistic, beautiful background (restroom), octane render, 8k, best quality, masterpiece, an extremely delicate and beautiful, extremely detailed ,CG ,unity ,wallpaper, (realistic, photo-realistic:1.2),Amazing, finely detail, masterpiece,best quality,official art, extremely detailed CG unity 8k wallpaper",
  "negative_prompt": "fat, paintings, sketches, (worst quality:2), (low quality:2), (normal quality:2), lowres, ((monochrome)), ((grayscale)), bad anatomy, DeepNegative, lowres, bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, worst quality, low quality, normal quality, jpeg artifacts, signature, watermark, username, blurry, bad feet, cropped, poorly drawn hands, poorly drawn face, mutation, deformed, extra fingers, extra limbs, extra arms, extra legs, malformed limbs, fused fingers, too many fingers, long neck, cross-eyed, mutated hands, polar lowres, bad body, bad proportions, gross proportions, text, error, missing fingers, missing arms, missing legs",
