Seamless perfect loop. She lies on her back on the bed, head turned to the camera, eyes closed, mouth open, tongue out, his cock already deep in her mouth. The only mover is his hips. His hips drive forward until his balls are against her lips, then pull back only until her lips are halfway down his shaft, never further, two hard fast strokes per second, over and over. She does not move at all. Her head stays still. Her mouth stays open. Her tongue stays out under his cock. Her lips stay wrapped around his shaft. Her body stays still. Her arm stays across her waist. Her hair stays pooled on the bed. His body stays still. His balls stay low and small. The only mover is his hips. No camera movement. Keeping the same angle as the still. Nothing grows, nothing merges, nothing slides. Perfect seamless loop of a short hard deep pump.
