A persistent issue with generating images of mermaids in sexual situations is the fact that it's hard to consistently get it to retain the full mermaid form while still keeping true to the prompt. Oftentimes, it will give the mermaid legs even when you explicitly tag out any keywords relating to legs, and that can be a headache to work around.

This is the key reason why I trained this lora to rectify the issue, to simplify things and ensure that it's easier to keep the tail intact while still keeping the sexual content. I may keep developing this lora further to iron out some of the less functional aspects, while diversifying the dataset. The goal is to include as many potential positions as possible so you'll have a good toolbox to use for various sex positions.

With the anima version out of the way, I decided to experiment with more concepts. The one I ended up adding was intertwined tails, which should aid in yuri, futa and general merfolk hetero content, as well as theoretically allow for lamia on mermaid stuff, even if that part is a bit wonky currently, which is ironic considering the vast majority of images teaching the intertwined tails concept was lamia on mermaid content. Either way, you can now use this model to make lamia yuri, so hooray. The concepts I didn't get to include in the Anima version that I really wanted there were mermaid tail/finjobs (primarily the latter since there's barely anything out there to use for it, and it's extremely hard to prompt), as well as cunnilingus (considering that the vast majority of mermaid cunnilingus art is of the mermaid giving the cunnilingus rather than recieving it). I might be able to rectify it in a future release, but for now I'm satisfied.

Illustrious Tags: mermaid sex, legs together, missionary position, cowgirl position, girl on top, tail raised, tail hug

Anima tags: mermaid sex, legs together, missionary position, cowgirl position, girl on top, tail raised, tail hug, intertwined tails

Illustrious version is optimal at 0.8, whereas you may wanna use Anima version at 0.7 to 1 depending on what you want to achieve, but I generally advice against 1 for tail hugs and intertwined tails.
