Elite international agent Amane Michelle comes to Japan to investigate a dangerous new aphrodisiac frequently used in train molestation cases. Acting as bait on a packed commuter train, she is attacked when an operative forces drug-coated fingers inside her panties, triggering uncontrollable orgasmic withdrawal. She wakes in the organization’s hideout, where her tall, slender body can no longer resist or refuse the pleasure. Surrounded by the molestation gang, she is gradually overwhelmed and completely defeated by the drug’s effects.
