I guess the words is wrong. "lacting"

Works beautifully at 0.7.

Here are some tips, use 'close up' or 'half body' for some very interesting effects, if you know what I mean 😳

Also 'from behind' and '1boy' if you want the guy to do the milking.

Works well at 0.5-0.7. For stability, I advise lactation in coffee cup, coffee cup on the table, (glass under breast) puffy nipples, one breast out, from below, hanging breasts, breast grab, leaning forward, flows into a glass, holding coffee cup, pull clothes, pulled by self, from below, hanging breasts, breast grab, leaning forward,flows into a glass,holding coffee cup. The previous commentator already wrote, but I will repeat after him close up or half body It’s better to add (spill past the glass) to the negatives, but even in this case there is a chance that it will flow past

The lora decreases image resolution significantly. Also the concept success rate is fairly low.

According on the suggestions in comments, this is the best prompt word I have tested: half body, from side, from below view, leaning forward, 1girl, big breasts, table, solo white coffee cup and saucer, cup on table, (cup under breasts:1.2), puffy nipples, nipple, cloth open, breasts out, (bare breasts:1.2), hanging breasts, grabbing own breasts, milkingself, (lactating into container:1.2), (flows into container:1.4), looking down

However, it is evident that this model is OVERFITING!! U must reduce the LoRA weight to 0.5 and dont use other LoRA

Fortunately, I found other LoRA can make a good pictrue U want and better than this: [Projectile Lactation - Concept] ← click

This is my generation work: Click Here See This Post

Use prompt: <lora:projectile-lactation-ponyxl-lora-nochekaiser:1>, from side view, table, solo white coffee cup and saucer, cup on table, cup under breasts, lactation to cup, looking down, face to cup, projectile lactation, lactation, grabbing own breasts, forced lactation, hand milking, excessive lactation, forced orgasm

U can did it too
