LoRA for tentacles latch on to a woman's breasts. Not with suction, but by grabbing (or biting) and holding on.

Anima_v1: Trained on Anima Base v1, but still works on Preview3 train checkpoints like WAI v1. Triggers are a bit different due to the switch to the Quen text encoder:

Base: tentacles

Double: double breast latch, skindentation

Single: single breast latch, tentacle breast grab,

You can use "skindentation" with single latch and "tentacle breast grab" with double.

Other things that were in the training data that seem to work are "Metroid \(creature\)" and "piranha plant", replace "tentacles" with those and use "__ breast grab", although it's a bit finicky.

IL_v1_D8: Reduced file size version, though it lost the compatibility with "Piranha plant" in the trimming.

IL_v1 - first version for Illustrious, seems to work well enough.

Main triggers (use one or the other, not both):

"double breast latch, tentacles": latching on to both breasts.

"single breast latch, tentacles": latching on to one breast.

Tags that might have some effect but can be unstable: "vines, plant" - makes the tentacles vine like and the grabbers leaf or petal like, "starfish" - biases towards starfish pasties. "Piranha plant" and "metriod \(creature\)" also kind of work, but that may be base model knowledge.
