Reverse Footjob, Upside Down Footjob, Footjob from Behind, Ass-view Footjob... Whatever you call it, here it is.

Strength 0.5~1.0 for both High and Low.

I usually start at 0.7 for both and adjust if needed.

GENERAL TRIGGER PHRASES:

Footjob. Her feet are upside down. 
The woman begins performing a footjob on the man. She moves her feet up and down. 
She moves her feet in long strokes, all the way up to the tip of his penis.

TWO MAIN ACTION PHRASES:

These phrases have a greater effect when using the NSFW checkpoint.

She uses her toes to grip the man's penis. The woman is squeezing the man's penis using her toes.

Start with this phrase. It is the 'weaker' phrase, but is often strong enough.

If this phrase is not strong enough, you will know because she may not rotate her feet correctly, toes may look really messed up, or she may twist her body around and grab the cock with her hands (Wan often interprets 'grip' and 'squeeze' as involving the hands).

If that phrase doesn't work, or gives weird results, then try the next phrase:

The woman brings her feet together on either side of the man's penis.

This is the 'stronger' trained phrase.

This phrase makes her wrap her toes more fully around the cock, but in some contexts it may make the toes look weirdly long, so I only use this if the first phrase doesn't work.

Trained mostly on toejobs, but depending on foot position in start image, she may perform a solejob.

It will struggle if your start image has feet in an impossible position, but she will still try.

I usually just start with a cockless image, use the nsfw checkpoint, and let the model decide where to position the cock.

Some preview videos were made with the NSFW checkpoint, some with base wan (FP8 scaled). See video metadata for checkpoint. Civit metadata is currently fucked, so you'll just have to guess which checkpoint was used.

I generally turn up CFG a bit when using this lora.
