This lora with "Pussy Vagina T2V/I2V" lora together work with T2V.

This is my creampie lora. This one I took longer than all previous loras I have trained, but fortunately I have accumulated a bigger pool of labeled video clips(I manually tag them with help from AI) that I can use towards my next training. It works pretty well and accurate when there's no penis in the picture, but the "pull out" effect will take a few tries to get right because my lora still hasn't figured out what a dick should look at in some angles, theoretically you can pair it with one of the penis loras, but it messes with your generation quality a bit, so just try a few times with different seeds and prompts. I got most of my thumbnails just doing that and it's not terrible.

Example prompt:

She is riding on a penis inside her vagina at the bottom of the screen. The penis pulls away from the vagina and some white translucent cum drips out from vagina in a creampie action.

The key words is white cum drips out of vagina , funnily enough, since I tag every video using "white cum" instead of "cum", you can change the color of the cum and where it's dripping from to get a totally different lora. It's really up to your imagination. But I'm pretty talentless so all the videos I create is just plain sex. :P

With more labeled videos, I'll take another jab at T2V probably starting from breast squeeze. WAN2.1 has a good idea what breast should look like and the physics, but knows nothing at all about penis and vagina, and I think this is why I didn't get a good result with T2V.

Lastly thanks to all the folks who have commented and liked my work, you guys are very kind and I'm having fun.
