A guy gets his dick worked over by someone using their feet, usually rubbing the shaft between the soles or sliding it along toes and arches. The art tends to linger on close-ups of feet wrapping, squeezing, and stroking, with precum smearing and a messy finish on the toes or top of the foot. Sometimes it plays into domination vibes, with the partner staying seated or standing while the guy jerks and squirms below.
