Animate the still photo of the naked woman lying on her back. She holds and masturbates the realistic hard penis rising from the bottom of the frame, using both hands to stroke the long shaft in smooth, continuous up-and-down motions. Her hands travel the full length of the shaft from base to tip and back again in a steady rhythm. Keep the camera completely still and fixed exactly as in the original photo—no zooming, no panning, no tilting, and never zoom her face out or change the framing in any way. Maintain strict POV so only the penis and her hands/torso from about stomach level upward are visible—never reveal any more of the man attached to the penis. Keep realistic skin, lighting, anatomy, and motion consistent with the original photo. Smooth, natural hand movements, subtle body responses, high detail, photorealistic.
