To be honest I am not happy with this model but it is the best LTX2 one I got so I want to share it with you anyway.

IMPORTANT!!!

Best to be used with a strength of 0.6.

In addition you should use the LTX-2 NSFW Best Breasts Lora at 0.3 strength.

I used the phrase: "a young woman with small breasts is standing, she looks down on her breasts in shock as her breasts grow. Br3ast3xpansion"
