Femdom strapon riding with ruined orgasm

The Queen of Femdom, adorned in latex and high heels, commands her helpless male slave to kneel before her. She mounts him, her massive strap-on cock filling him up to the brim. With each brutal thrust, she forces him to walk on all fours, adding to his humiliation. The intense pain mixes with pleasure as he feels his orgasm building. But when he thinks it's close, she cruelly stops, leaving him hanging on the edge of ecstasy. As punishment for his inability to please her, she denies him release, leaving him weak and begging for more. This torment continues until she sees fit to grant him mercy, or perhaps vengeance.
