i modified my prompt for :

Cinematic close-up shot of an ultra-realistic, erotic NSFW scene featuring a stunning female facing back-left. A nude male enters from the right, masturbating his extremely large, erect penis. He positions himself behind her. His penis makes lots of cumshots made of very thin ectoplasm translucid realistic cum strands shoots from his penis and lands fully on her hair, covering her hair in lots of cum, the cum remains on hair in a sticky and gooey way, slightly thicker with each new strand of cum. The scene emphasizes the detailed cumshot on her hair, highlighting detailed wet hair and sticky hair. Soft, consistent lighting enhances the warm, sensual atmosphere, with seamless transitions for a dynamic, cinematic experience.
