They sit, we tie, it's all in good fun!

Tied Sitting

Three

Third times a charm! Trained on new material(s) and an all around cleaner and better captioned set, now you can just sit back and relax, and not move until someone unties you.

Prompts matter for this one and some seeds do not agree with the concept but when this version gets it right, as it often will, it gets it so right.

A beautiful {Russian|French|Swedish|Swiss|Latina|Austrian|Dutch|English|American} woman is tied sitting {in a chair, {her legs down and open with her knees held apart and her ankles tied to the chair legs|her legs spread wide and lifted, restrained at the {ankles|ankles and knees|ankles, knees and thighs} with {rope|straps} attached to {the wall|a horizontal wooden beam on the wall|a metal frame}}|on a black padded bench with her legs spread {and lifted |}tied with rope to {the wall|a horizontal wooden beam on the wall|a metal frame|hooks on the wall}|a wooden panel on the floor with her legs spread wide held at the ankles by rope tied to the panel in the bottom corners of the frame|bound to a metal chair and tied with rope to a black metal pipe frame|on a {black|red|white|blue|yellow|teal|multicolor|corduroy|tan|orange|green|cyan} couch tied with rope coiled around her ankles, knees, wrists and arms secured tightly to various points around the couch} {in a bondage room|in a living room|in a basement|in the corner of a {red|white|blue|green|rainbow|teal|pink} room}. She is held stable in her pose attached to the fixtures.

Her arms are {at her sides with her hands hidden behind her thighs|up with her wrists bound above her head with rope attached to fixed point outside the frame at the top|straight out to the sides with ropes coiled around her wrists{ and arms||}}.

The view is from the front and the pose is symmetrical. 

She is {wearing a {red|blue|black|yellow|orange|multicolor|rainbow|gold|leather|silver|latex} {blindfold|pair of panties|bra|dress|bodysuit|hoodie|pajamas set|costume|volleyball uniform}|naked with {huge|large|medium-sized|small} breasts and a {hairy|shaved} pussy}.

She has {very long|long|medium length} {blonde|black|brown|dirty blond} hair.

She {has a blindfold over her eyes|has a big smile on her face|has a {red|black} ball gag in her mouth|has a shy expression|looks concerned and lost}.
Lighting is {bright and even|soft and even|dim in the background with a spotlight on the subject|provided by lots of candles}.

Two

Better performing version of this concept, fed with partials, close-ups and more accessories. 5e-5 for ~13 hours. ~ 256, 256, 48. I test the loss curve at the beginning, middle and end of obvious plateaus, in this case the smoothed loss at epoch 70 was ~0.031.

Wildcard Prompt

Front view of a beautiful {Russian|French|Swedish|Swiss|Latina|Austrian|Dutch|English|America|California} woman with {very long|long|medium length} {blonde|black|brown|dirty blond} hair tied sitting with her legs spread on {a chair|a bench|the floor|a pad|a pillow|a gynecology chair|a dentist chair} {in a bondage room|in a living room|in a basement|in the corner of a {red|white|blue|green|rainbow|teal|pink} room}.

{Her arms are at her sides with her hands hidden behind her thighs.|Her arms at up with her wrists bound above her head|The restraints wrap around her {belly and thighs|ankles and wrists|ankles and thighs}, securing her firmly restricting any movement}.

She is wearing {{red|blue|black|yellow|orange|multicolor|rainbow|gold|leather|silver|latex} panties and a {red|blue|black|yellow|orange|multicolor|rainbow|gold|leather|silver|latex} {bra|top|shirt}} and {red|blue|black|yellow|orange|multicolor|rainbow|gold|leather|silver} socks.

Her skin is pale and her body glistens with moisture in the light.

One

~8 full body videos, ~6 ones including the Hitachi magic wand (reproduced with limited success) and a bunch of close ups to teach the right details, this training run is worth the post. I may add more videos and retrain this at some point to try to improve the details, but until then, enjoy the one, the only, the... One.

add the second trigger term "v1bed" and a phrase "holding the h1tach1 magic wand vibrator to her vagina" for the secondary concept.

Potential Future Directions

I have a dream now, of training on my entire BDSM training sets, expanding to various positions, restraint types, settings, clothing, etc... some sort of BDSM Uber LORA. I think that my footage and captioning skills are where they need to be, but it's likely that I'll need to run a very low learning rate for 2-3x as long as I usually do to get something stable. Meanwhile, I'm going back through the footage I set aside looking for more good clips to bonify the datasets; this will take lots of time and captioning needs to be accurate and strategic for results to be good, so I can't rush this at all.

• I may eventually attempt some of the other concepts people have suggested (sex positions++), but many of these already exist and I'm less keen on producing more of the same.

• There are many other BDSM concepts that I'd like to train, but finding high quality footage of clear and focused examples of the more obscure ones is difficult at best.

• I also may eventually train for WAN, but I don't use that model and the time it will take to prep and run those trainings will cost me lots of time and energy, ultimately for LORAs I won't personally use at all, so we'll see. *What I am open to is sharing my datasets. I'm not the possessive/selfish type at all. The only thing is that I have spent tens of hours collecting and captioning these sets, so I reserve the right to be be selective about who I share stuff with.

HunyuanVideo doesn't love being trained on multiple concepts. In my experience this is more likely to result in Frankenstein's BDSM LORA.

Apparently WAN does though. 🤔
