Tuna Sakuma and Ikura Unno wander the city searching for a missing friend until a message leads them to the Black Lion Society’s office. There, wicked men deceive the two adult women into drinking a powerful aphrodisiac and they lose consciousness. They awaken restrained and trapped in relentless forced-orgasm torture, convulsing, wetting themselves, and nearly passing out. Though they desperately resist, the overwhelming pleasure awakens their buried lust and conquers both body and mind, leaving their fate in the hands of their captors.
