Foot Crush Cage Edge Relock Denial

She starts by pressing her foot down hard on your cage, trying to crush it into place and make you feel completely trapped under her weight. Then she opens the cage and keeps you edging for a long time, teasing you right to the edge over and over without ever letting you finish. When your erection stays too strong, she uses her foot to push it down until it goes soft, acting like the session is over before bringing it back up again and continuing the torment. She repeats the cycle of rising arousal and forced collapse until you are exhausted, then orders you to put the cage back on and leaves you locked up again without release.
