Model creator: ArtisticWaifu.

Trigger words: waifumilk, lactation or lactating

Option words: grabbing own breast, cup under breast, lactating into cup, lactating into glass, glass under breast

[If you want only one breast lactating, prompt her some clothes and put "one breast out" in the prompt, or try to cover the 2nd with hands or else for this version.]  Optional: Adetailer & High-Res Fix.  Its a bit unstable cause of the Dataset. known issues in this version:  not too easy to make only one breast lactate when fully topless. (both breasts out) hands are biased towards grabbing breasts. [you can still prompt them differently] sometimes grabs wrong breast sometimes misses the cup. :D sometimes cup/breast position wrong. hands could be better sometimes. not too versatile in poses, but feel free to experiment.
