Setouchi Kurage is a kemono artist with a focus on moderately (not excessively) chubby/thick girls. They particularly do a lot with rabbit and sheep characters. Check them out at:

This LoRA was trained on both SFW and NSFW art. It seems to work a bit better with PonyV6 than AutismMix, but both have worked for me.
