I didn't see a lora of this concept for Anima, so I made one.

Trigger is "tentacles under clothes"

Optionally use "see-through" to make the tentacles visible underneath the clothes.

Works with a range of outfit types, though for bodysuits and leotards you need to avoid "skin tight" and use "impossible bodysuit/leotard" instead.

Doesn't support sex completely under the clothes. Might revisit if that's a big gap in capability.
