Like MILF model, this can be adapted to SFW, ecchi or NSFW output. [tag for it appropriately, adjust settings/weights as needed]. Made with retro art ranging from 1990s through 2015-ish. Images obtained under fair-use, free web images used only.
recommended settings:
weight: 0.4 to 1.2
CFG: 4.0 to [max]
steps: 20 to 60
may need to lower settings to achieve more SFW end work. Made using wide range of images.
