A fast, tight, intense loop. She starts exactly where she is now. She drives her mouth all the way down until her nose is buried in his balls, balls deep, then comes back up to exactly the starting position — not all the way to the tip, his cock head staying inside her mouth — then slams all the way down balls deep again, back to the starting position, again and again, hard and fast. Each time she drives down, more thick cum spills from the corners of her mouth and drips down her chin, building up more every stroke. Her head slides, it does not rotate — her chin stays up, she does not tilt her head down, she does not look down. Her jaw does not drop, her mouth stays sealed around his cock, her tongue stays inside her mouth. Her expression stays exactly the same. Her eyes stay half-lidded and locked on the camera, never closing. He stays completely still. Her body stays in the exact same pose. Camera static, frame static, background static, lighting static.
