Brutal Dildo

The field where I am writing this right now has a label, simply "Description*". The label also has a description... you know, that little line of text below a title or label. The description for Description reads:" Tell us what your model does"...

Well... I'd really rather not, but you know what they say! A picture says a thousand words, and videos, I assume, are at least as wordy... so just look at the showcase, okay?

If you download one of the showcase videos and drag it over ComfyUI, you'll get the prompt and a workflow.

I have no idea what I am doing.

You thought I was done?! HA!

I put a better action phrase into the captions and simplified them for a win win of better tighter... captions. I tested a few epochs and got up to 47, haven't tested past it yet, this thing is magical.

Revised Wildcard Prompt

A beautiful {Russian|French|German|South Korean|Dutch|Swiss|American|Swedish|Austrian|Ukrainian|Portuguese|American|Canadian|Colombian|Australian} woman is using a brutal dildo inside her {vagina,vaginal dildo riding|anus,anal dildo riding},

She is naked{ except for {{black|pink|red|blue|green|orange|yellow}socks|a bracelet|a {black|pink|red|blue|green|orange|yellow} {bra|hat|scarf|shirt|tube top|tank top|sports bra|}}|},

she is {barefoot|wearing {black|pink|red|blue|green|orange|yellow} {thigh|knee}-high socks|wearing a {black|pink|red|blue|green|orange|yellow} shirt},

She is squatting, bouncing her hips up and down vigorously, pumping the shaft of the {red|green|blue|orange|yellow|black|white} {horse-penis|scaly|notched|tentacle-shaped|ribbed|spiked} dildo inside her,

Two.WAN

Same run as One, just a different epoch. I extracted many, tested all, cried, in part from the beauty and in part from the failures and came up with epochs 24, 48 and 53. They kept coming back with interesting renders. 48 seemed hellbent on proper dildo penetration, so that became ONE. Today I work-shopped better prompts and found a real winner. It'll probably unleash 48 as well, but 53 got this massive habit of creating massive dildos, but it was missing some consistency. Well! Pop in (pun intended) this huge (pun intended) Wildcard template update and BAM (pump intended), whoa, holy f--k that's not possible!

Epoch 24 is not uploaded, but I kept it. It has a certain flexibility that 48 and 53 lack, but also produces much smaller dildos, hence it not making the cut. If you're curious though, maybe I'll upload it.

One.WAN

I automated some caption transformations to save time so this run had a couple caption issues, however this epoch was strangely capable. I'm weary of my dataset but finding clean material where models aren't dressed weirdly or covered in tattoos is tough, so I'll need time, precious precious time! :P

Wildcard Prompt

A beautiful {Russian|French|Swedish|Swiss|Latina|Austrian|German|Dutch|English|Irish|Portugese} woman moves her hips up and down while an upright dildo remains firmly inserted inside her vagina throughout the motion.

{low angle, ||} {front view

She is {happy and blushing|wincing|furrowing her brow and grinding her teeth|screaming from pleasure|extremely surprised|moaning from pleasure}. She has {large|medium|small} breasts and a {hairy|shaved} pussy.|back view}

She has {very long|long|medium length} {blonde|black|brown|dirty blond} {straight|curly|wavy|pony-tailed|pigtails|styled} hair and is {squatting|kneeling} {against a simple {space|black|white|red|blue|pink|teal|rainbow|multi-color|tie-dye|mandala} background|at a look out point above a night cityscape|in a modern bedroom|in a white tile bathroom|in a shower stall|in a tent with open door flap showing snowy mountain peaks|in a living room|in a dirty basement}.

She is completely naked {with glistening wet skin from oil and profuse sweat with no tattoos|except for {a colorful crop top|a beret and dark thigh-highs|a vivid color bra|a beanie|a collar around her neck|bracelets and hoop earrings}}.

While the dildo is mostly hidden inside her the whole time, it is {giant|huge|thick|massive} {black|red|white|beige|multi-color|pink|purple|blue|glass} and {notched|ribbed|horse penis shaped|dragon penis|tentacle shaped|smooth|irregular|spiked|bumpy}, evident when her hips rise.

Brutality

I'd say this is the final version but I thought Three was going to be the penultimate LORA for this concept. Truth is that even this one has some weaknesses, namely that it doesn't do anal very reliably, especially from the front. However, it will render anal from the front if you add "leaning back" to the prompt, I guess that one video showing that pose made it a rule.

-You lean back, straight up your ass!

This version was trained on a cleaner set with better captions. I changed to 24FPS from 25PFS. 6e-5 was my learning rate with a smoothed loss just under 0.03 for the best performing epoch (90, although 80 was doing really well too). 21 videos total, equally distributed between front and back views for 50 frames per video. Total training time was ~18 hours.

Other versions

4.2.0

The runner up! As I zeroed in on optimal captioning strategies, this run did the trick nicely with much better faces. Enjoy!

front

All front view, mostly low angle, 5e-5, 256x256 and 432x240 for 50 frames. This one delivers brutally. Try "notched, scaly, horse, tentacle" with various bases. No back views trained at all. Works very well and seems very flexible. The lower resolution might be hurting things like hands though...

back

I finished training this a couple days ago but my tests were not delivering the results I was hoping for. Multiple concepts are harder for LORAs to hone in on and this run didn't impress.

However, this version does the back view very well, while front does front views better, so if that's what you're going for, you can probably skip back. It is what it is...

Three

Because I found that back will place the dildo in front of the woman and not always inside. and not a single one of my videos was not 100% focused on the penetration, clearly something went wrong.

I studied the concepts and dived deep into the subtle effects captioning and prompting provide to this process. I learned even more about captioning, including some very non-intuitive things, all detailed at length in my training guide. I think the fruits of my labour and patience with training a multi-concept LORA have mostly paid off, or maybe my prompts are just better... (Narrator: His prompts were better.)

Prompting Tips

I changed the Wildcard template:

• I had to remove "in and out". That was counterproductive.

• I had to add "inside her vagina" right after the key phrase, that seems to really have the right effect.

• Mentioning that the shaft is "pumping back and forth" disconnects it from the description of the dildo itself, which I think also helped things get rendered in the right places.

Prompt in natural language. Describe the most important parts of your concept right up front, leaving deeper tokens as modifiers rather than scene definers.

Anything you write, the model will try to render, so make sure you actually want to see what you are describing. Sometimes you want to imply things that aren't actually visible or think about how the model sees it, versus what your understanding of the scene is.
