A "teacher-loving older sister" appears on the train to hunt herbivorous men! She sniffs out the scent of masochistic men and boldly seduces them! Once he gets a rock hard erection, she puts her hand in her pocket and gives him a close handjob! He jerks off in his pants... and it's sticky... He can't resist the devilish technique of the sadistic torture and ends up ejaculating inside his clothes! But it doesn't end there, and the excited slut's demands become even more extreme...
