An elite undercover spy infiltrates an illegal aphrodisiac factory with orders to use her mask's high-voltage suicide function if she fails. The mission collapses, and the enemy prevents her death while subjecting her naked body to a hell of pleasure. Her H-cup breasts become toys, undiluted aphrodisiacs trigger relentless orgasms, and her hypersensitive pussy is piston-fucked without rest through repeated creampies. She insists she is not climaxing even while squirting and convulsing. When enemy technicians finally disable her organization's mask, she faces a final choice: betray the organization and confess, or remain trapped until the orgasms destroy her mind.
