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.

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} *****.|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.

Versions

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 **** very reliably, especially from the front. However, it will render **** 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

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.
