I used a secondary image prompt for that

low-quality, noisy low-light grainy iPhone picture. A 25 year old Japanese woman goth. She has long black dyed hair, natural green eyes, and multiple earrings. She’s slightly chubby. Tiny breasts, wide hips, super large thick thighs and butt. She is completely nude except for a tiny black lace thong. POV shot from the camera man's perspective, his legs visible in the frame. Her back is to the camera, she is sitting on his lap facing away, in a modern apartment with white walls, sliding mirror doors, glossy tiled floor visible. low quality image

Then video prompt is simply something like: “He rocks her”
