This is a retrain of my Hyperballs LoRA dataset for Illustrious and Pony models. These checkpoints are already pretty good at hyper proportions, including for testicle sizes, so you don't strictly need this. However, 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, not unlike the "oversized balls" tag.
It effectively 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.
Of course, YMMV with the model, lora weight and emphasis used. As per any hyper-oriented models, other factors that might affect generated size would be the presence of backgrounds, pose, layout, aspect ratio and whether you're prompting a generic character or a character known to the model - the latter usually causes models to try and keep closer to their canonical proportions.
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:
"clenched balls" - (version 4+ only) Draws that characteristic pouch of scrotum inbetween the two testes usually meant to imply cremaster contractions.
"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 scrotum 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.
Description
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.
Tested working on https://github.com/lllyasviel/stable-diffusion-webui-forge. If this doesn't work in your setup, please refrain from downvoting before trying the unpruned version.
Original unpruned version notes:
Used weighed training to diminish the effect of dataset noise and improve anatomy.
Added a few more "self sitting" examples to the dataset to address popular demand. It is still not very reliable at it, but should be easier now.
Modified some "testicles on floor" and "testicles on ground" examples to better shape the testicles when they are resting on the ground, causing them to slightly flatten under their own weight. This can help avoid the "two orbs" look when prompting those tags at high weights.
