I've used a dataset of 26 videos with 24fps and each of them about 5~seconds long to train a model for doing thigh sex. It has been trained on the Wan 2.1 14B 480p i2v model. From my testing the concept works on both humans and interspecies.

It works with Buttjob too. Just use "thigh sex" as prompt.

I didn't test if its works with T2V, so feel free to experiment.

There is not really a trigger word, but your prompt should contain "thigh sex".

Example:

A video of a man and woman having thigh sex. 

Adding "thigh sex" additionally as tag seems to help too:

thigh sex. A video of a man and woman having thigh sex.

Important:

Please make sure to credit the LoRA. Turns out WAN LoRAs are expensive to make.
