First shot at a breast LoRa and first posting of NSFW here. Trained on Caucasion breasts, but seems to work with other skin tones okay. Produces firm, natural shaped breasts, not blobby, or generic looking like so many generated by Flux. Of course, results will vary by checkpoint.

Works without a trigger, but you can use brst-nip, breast, areolae, nipple

Edit/Update: Done some testing with other breast LoRAs and this plays well with saggy, and somewhat okay with breast size LoRAs.

Klein version: Very dependent on model/checkpoint. Images are using Flux2-Klein-9B-True model. The only way to really alter breast size is with one of the sliders out there. The natural breast shape is retained, regardless of size. The texture of the areolae can be influenced with prompting (bumpy areolae will add that, otherwise smoother textures will be generated). The excellent breast size slider LoRA I used for the sample images has been removed from Civit for some reason. If there are no more out there, I may train one.

Please post your generations here. Love to see your work, let me know what you think!
