Full nelson sex position for Wan I2V.
All the videos in the showcase were created using variations of this basic prompt: "fullnelson. A video of a man and woman having ass sex in the full nelson position. The woman is on top of the man and is being penetrated by the man's penis in her ass. The man is thrusting his penis hard and fast into the woman's ass repeatedly causing her feet to to bounce up and down in rhythm to the man's thrusts."
The LoRA works for both ass and vaginal sex, just change your prompt to reflect which one.
Works well for the complete full nelson position with the hands behind the neck, or with just the man holding the legs back. In my testing I found it can work decent for the reverse cowgirl position too.
It was trained on as diverse of angles of the full nelson position as I could find, it should work on any angle from front facing to side profile view. It was trained on 28 videos for about 56 hours on the 480p 14B I2V model using two 4090s and diffusion-pipe.
