The second installment in the comic collaboration series, co-produced by Sanwa Publishing, features Mei Kase as she transforms into an aggressive seductress devouring men on the train! The moment she experiences sexual humiliation on a train for the first time, she's overwhelmed by unprecedented pleasure, turning the train into her sacred space from that day on. By day, she's a dignified, bespectacled beauty teaching at school, but in secret, she becomes a lustful woman chasing ultimate ecstasy—ejaculating on every passenger during wild train orgies. Captivated by group sex on the train, her intoxication with pleasure is vividly portrayed.
