use the reference image as the exact visual foundation and first frame. Keep the perspective, composition, proportions, and spacing absolutely unchanged from start to finish. No zoom, no reframe. An elegant woman, 28 years old, stays bent forward over the open engine, measuring the oil with the dipstick, her face in clear side profile near the motor. A handsome mechanic, 38 years old, kneels close behind her, shirtless under fully worn blue denim overalls, wearing black work gloves, posture intimate but gentle. She speaks from the start in a low, breathy, provocatively vulgar yet playful and openly flirtatious tone. Clear American English, word for word, perfect lip sync, she says, "I think you'll have to show me how deep the dipstick goes", Her mouth clearly articulates every syllable, While, she keeps her body over the engine and lifts her left leg and put her left feet onto the Radiator grille and exposes her tight vagina toward the mechanic, she glances back just slightly, a teasing smile forming. The mechanic gently rests his chin on her lower back and lightly holds her waist. His expression soft, overwhelmed, and tempted. The dress fabric behaves naturally with movement. The set remains a real mid-1950s Shell repair shop, warm dusty light, strong micro contrast, subtle film grain.
