American Woman

[Nyghtfall3D]

Now that I can control physique and breast size with Nano Banana Pro, I decided to have a bit of fun with a couple of non-fetish pieces. For the first piece, I had Nano render it as a candid photo taken with an iPhone. She's the kind of woman I've long fantasized about seeing in a grocery store. She's also wearing a pair of my sandals.

What do you use for breast size? Even the basic models are pretty fluent in those official size designations like A-cup, DD and such. It was so funny when I found that out.

What do you use for breast size?

I alternate between a C and D cup, depending on what I'm in the mood for. I tried DD, but they were too much - I didn't even know I had an aesthetic limit (cheeky grin). This prompt is how ChatGPT taught me to work with Krea's NSFW filters while preserving proportional realism:

Her bust is full and voluminous with clearly projected forward mass, targeting a natural D-cup appearance relative to torso scale. Breasts display realistic weight and gravity: gentle downward pull, subtle lateral spread, rounded lower poles, and natural cleavage separation. No exaggeration artifacts, no compression or fusion, no artificial lift. Bust size scales naturally with ribcage and shoulders—no micro-torso inflation, no floating placement.

Are you writing an AI prompt or a geeky Romance Novel there Nyghtfall?

I'll write whatever GPT tells me will get past Krea's filters, even if it reads like a technical manual for a bodice ripper.

Incidentally, this is how I got that bikini past it:

She is wearing apparel identical to the attached reference image, with accurate fabric tension, fit, and proportions faithfully preserved.

is that the same girl in both images? hard to see proportions with the pose in the first image, but love her shape in the second one. If you long to see women like this in a grocery store, you can come down to TX, I see them all the time

I can't believe NB pro even lets you prompt "breasts" that is usually the key word for flagging

Ask ChatGPT to give me the prompts I can add to any model for a full round F cup size, LOL

is that the same girl in both images?

Yup.

According to GPT, prompts for breasts are doable - even on Krea - as long as, "the language stays anatomical, proportional, and realism-anchored (not fetishy or exaggerated)."

Here's what I just requested for you: give me a prompt to generate a woman with realistically proportioned F cup breasts

This was its response: Here’s a clean, model-friendly prompt you can drop straight into Nano / Nano Banana Pro / similar systems.

And the prompt:

Ultra-realistic photographic image of an adult woman with a tall, athletic-curvy build and naturally proportioned F-cup breasts.

Her bust is full and heavy with natural mass, clearly larger than average but balanced to her ribcage, shoulders, and torso length. Breast volume is distributed naturally with rounded lower poles, soft upper fullness, and clear forward projection without artificial lift.

Breasts respond realistically to gravity: gentle downward pull, subtle lateral spread, and natural skin tension. Cleavage appears only where posture and garment allow, with clear separation—no fused, compressed, or inflated appearance.

Chest width, shoulder span, and waist-to-hip ratio scale appropriately to support the bust size. No micro-torso, no ballooning, no stylization.

Realistic skin texture, natural breast curvature, accurate anatomical landmarks, and believable weight distribution throughout the body.

Shot in neutral lighting with a realistic lens perspective (50–85mm equivalent), natural posture, and true-to-life proportions. No glamour distortion, no anime or fantasy exaggeration.

EDIT: Nano rendered a plus-size woman via Gemini, so I adjusted her physique to something closer to what we like. Gemini rejected it, and Krea blocked it. Apparently, they think an F cup on a rail-thin woman is too unrealistic, and thus, fetishy.

LOL, thanks for trying though. Yeah, ChatGPT is describing a natural heavy women that is proportionate and big all over, not a normal size woman with extra large breasts

I tried parts of that prompt and reworded parts in Krea to see if I would get any warnings or if it would make a difference.

"Her bust is very full and heavy with natural mass, clearly much larger than average and unbalanced to her ribcage, shoulders, and torso length. Bust volume is distributed unnaturally with rounded lower poles, soft upper fullness, and clear forward projection with artificial lift."

Worked well in this Zimage image combined with other prompts, but when I tried it in other images, I got warnings, so there is no rhyme or reason on when or how they flag something, it's all luck
