The only thing that moves is his hips, and his cock with them. Everything else is still — including her hips. THE ONLY MOTION — HIS HIPS, his hips push forward, driving his cock straight down into her mouth and deep into her throat, then pull back, drawing his cock back out to exactly where it started. It repeats the same stroke, short, hard and even, no pause, no change of rhythm, no change of depth. His cock never leaves her mouth — the top of the stroke stops while the head of his cock is still inside her mouth, and the bottom of the stroke buries it in her throat. Every stroke travels the same short distance and returns to the same starting point. THE LOOP, perfect loop. The last frame is identical to the first. It repeats seamlessly. NO SCALING, his cock and her face stay exactly the same size. Nothing grows or shrinks. HIS BODY, his hips are the only part of him that moves, and they move only forward and back in one straight line. His legs do not move. His knees do not move. His thighs do not move. His feet do not move. His torso does not move. His shoulders do not move. His arms do not move. His hands do not move. His head does not move. HER HIPS — SEPARATE AND DEAD WEIGHT, her hips are separate from his hips and his thrust does not reach them. They are heavy, pinned and dead weight. They do not move at all. They do not follow him. She does not react. They do not rock, do not sway, do not bounce, do not roll, do not shift forward, do not shift back, do not lift, do not drop. Her butt stays pressed into the sheets. Her hips stay in exactly the same place from the first frame to the last. HER BODY, she is completely still. Her head does not move. Her neck does not move. Her face does not change. Her expression does not change. Her eyes stay as they are and do not open or close. Her mouth stays where it is, open around his cock by the same amount. Her lips stay where they are. Her throat does not bulge and does not move. Her shoulders do not move. Her arms and hands stay where they are and do not move. Her breasts do not move. Her chest does not move. Her stomach does not move. Her legs do not move. Her legs stay folded back over her head the whole time and do not unfold, do not lower, do not straighten, do not drift. Her knees, feet and thighs stay where they are. Her whole body holds the same shape from the first frame to the last. THE BED AND BACKGROUND, the sheets do not move or ripple. The mattress does not move. Nothing in the background moves or changes. THE CAMERA, completely still. No pan, no tilt, no zoom, no push in, no pull out, no shake, no drift, no angle change, no height change. The framing stays exactly the same. THE LIGHTING, does not change. No flicker. The shadows do not move. The brightness and colour stay the same. RULES, nothing morphs, warps, stretches, melts or wobbles. No new objects. No body parts appear or disappear. Nothing changes shape or size. The only thing that moves is his hips — not hers.
