Prompt

A woman in her 20s with long white hair, naked in an overcrowded, dimly lit passenger train carriage. She is enjying having sex between two men, all standing. The man in front of her has his penis inside her, his hands holding her thighs, lifting her legs around his waist and dangling them to the side. The man behind her is having sex with her, anally, his hands gripping her hips and breasts for leverage. The window blinds cast diagonal shadows across their intertwined bodies. The woman's face abstracted, head tilted back slightly, her white hair cascading down, blending with the ambient light and shadows. The motion blur of the train in motion subtly visible through the windows, adding a sense of dynamism. The scene captures a raw, sexual tension, with long shadows and stark contrast highlighting the curves and movements of their bodies against the industrial, urban backdrop of the train carriage.
