Version 1.2 Update: Higher quality and expanded dataset. It can now do cumshots where the woman keeps sucking and you can see the cum dripping out of her mouth. The I2V version can handle images where a penis does not start out in the image.

Note that all of the previews were created using the lightx2v (self forcing) lora. You may get better movements without it, but I didn't do much testing without it. The workflows I used can be downloaded by getting the "Training Data".

T2V tips: It actually seems to still maintain motion very well at 0.7 strength, and you'll get more facial variety that way. I seem to get best results at 0.95 strength for whatever reason. You can add in a penis lora to help it out.

I2V tips: If the penis does not exist in the starting image, you probably want to add a penis lora to your workflow so it has a better shape. You can trigger it with something like:

A penis appears from the bottom of the frame centered at the bottom and pointed straight up.
If you want cum to appear:

White cum shoots out of the penis.
This was trained on 4 different angles, here is how to trigger them:

A woman is lying on her stomach between the legs of the viewer and performing oral sex on a man. Her head moves up and down as she sucks the penis.
An overhead view of a woman kneeling between the legs of the viewer and performing oral sex on a man. She moves her head back and forth as she sucks the penis.
A woman is leaning over a man positioned in between the legs of the viewer and performing oral sex on a man. Her head moves up and down as she sucks the penis.
