Sissy Maid in Hot Pink Dress and Chastity Is Locked to Her Dildo Stand

Sissy in hot pink PVC maid dress is locked in chastity and locked onto her dildo stand with a massive dildo in her boi pussy. She has to ride the dildo until she cums, but if she cums then she doesn't have to be unlocked from her chastity cage! What would you do?
