I just published the next LoRA from the poll: BDSM - Tied to bed
This one tends to mess up faces quite often, but if you lower the strength to around 0.65 it works. However you'll get more images with the position not being perfect, or missing ropes then. It was a bit tricky to get done, since most of the source material is quite low-res. That's also the reason for the messy faces.
At least I think so anyways, as it could also be that a few images contained ball gags and blindfolds. I'll do some more testing and try to release an update soon to have better results across the board.
'Gag' is also prompt-able btw, but it rarely comes out good. Give it a go, maybe it works better for you.
It can do both 'face up' and 'face down', if you prompt it for that.
At higher strengths it seems to zoom out more, showing the whole body including the tied feet, which is nice. I recommend only doing that in the 'face down' position for now though, because otherwise you'll have bad faces.
If you use 'close up' you will see the upper body and a bit of the legs, and the face will be mostly fine. With that view it does great in combination with my POV Missionary Vaginal + Creampie LoRA. I had no real trouble with bad faces then either.
As always, these are the settings I used for the previews:
Model: UberRealisticPornMerge
Sampler: DPM++ SDE Karras
CFG scale: 5
Steps: 30
Enjoy!
