I found this pic in my drive, probably from a user. Sorry, I don't remember the original creator. My credits here and thanks.
So, I decided to push the limits of grok trying to do a BobJob. The BobJob is the supreme fantasy of thick hair lovers. As a thick hair lover, my personal favorite length is waist length, but probably the long bob until the shoulders is the supreme expression of what hair thickness is.
I remember old Timiblaky 3D Art. He draw a lot of "BobJobs". The concept is really exciting: A man with his erect penis is standing on his foot and a seated woman with a really thick bob shake her head and make him cum only rubbing her penis with the weight of her thick hair. With blut sharped ends it's probably the best bob to do this. I don't know if it's possible to perform... I've never seen an bobjob in all his glory. Probably never filmed. But with this pic I tried to do it using Grok. Grok is probably the best AI for SFW hair videos. Grok understands perfectly the physics of the hair movement, and don't have problem with the fetishes not fully sexual (without sex or nudes).
That's not perfect, but is really nice.
THE FILES:
The prompt I used:
Camera fixed. Nothing changes in the picture. The wood stick with roundedn end is fixed to the wall, does not move, does not change at all. She shakes her head turning left and right brushing the wood stick with her hair. She is the only element moving. She looks right and she doesn't turn to see the stick
The wood stick is always buried in her hair.
ENJOY
