This is a mostly lazy retrain of my Hyperballs LoRA dataset, on Pony Diffusion XL V6. Its also working pretty well on AutismMix SDXL. I've been making some XL style loras for private use and I threw the same configuration at this concept, using the same configs. Turned out pretty good.

The aforementioned XL checkpoints are already pretty good at hyper proportions, including for testicle sizes, so you don't strictly need this. It might save you a lot of rerolling, particularly for "gigantic" testicles (now consistently larger than the character) and extreme disparity between penis and testicle sizes.

What follows is the description for the 1.5 version of this LoRA which largely still applies.

Redefines most "testicles" to be softball sized at the very least. My goal was to allow for bigger testicle sizes and more contrast between testicle and penis sizes since most futanari-centric models are already primed for huge and hyper-sized penises.

"huge testicles" is intended to make the combined size of the testicles as large as the character.

"gigantic testicles" is intended to make them larger than the character, possibly going off the frame.

Of course, YMMV with the model, lora weight and emphasis used. Trained on NAI animefull, lower the lora weight if it's frying on your merge.

Has penis size tagging so that unprompted penis size will be strictly smaller than the testicles, but you can try for larger sizes. "small penis", "huge penis" and "hyper penis" were used.

Try the following:

• "sagging testicles" - self explanatory
• "testicles on ground", "testicles on floor" - Should help shape testicles resting on a surface (typically the ground)
• "squishyballs" - tag used on pictures where the testicles are visibly deformed from being pressed against something (a limb, a surface, the ground, etc)
• "balls behind" - tag used on pictures where the testicles were located behind the thighs.
• "self sitting", "sitting on balls" - Ow! My Balls! Primarily used on pictures with "gigantic testicles".
• "backsack": The stretch of foreskin that joins the testicles with the groin, visible from behind. Slight overlap with "sagging testicles". Can be used with "perineum","pussy" or "vulva".
• "hyperballs" used to be the activation word common to the entire dataset but I'm having better results without it.

• This is a prune of 3_0 WT at sv_ratio 25 and same original dimension, done to address filesize complaints.
• For ease of use, I added back the metadata lost during the weighed training process, making this the recommended version.
• Results may vary extremely slightly from the unpruned version. The OP pictures were made using the same prompts and seeds for easy comparison.
