It still a very chaotic Lora but now you have some control over it with keywords, look at the pictures for reference, here is the deal:
1 - keyword "boob tentacle" is intended to make the tentacle wrap around the boob and give a firm squeeze, the classic grab.
2 - keyword "nipple tentacle" is focused on the tip , to tweak a nipple, is intended for flat or small chest but works on larger ones too.
3- no keywords, regular prompts like "tentacles, tentacle sex, and others" it is intended to call upon the regular red tentacles and do regular tentacle stuff.
4- keyword "large tentacle" this calls upon the pink large one, that infamous one from the first 3 ovas, good stuff.
the keywords for nips and boobs cannot be combined as they do diferent things, overal expect a lot of chaos, lots of re-dos and inpaintings, but it works far beter than before!
enjoy.
