Rino Sakurano sometimes gets groped on her train to school. She wants to call the culprit out, but fear of a violent reaction always silences her. Then one encounter feels completely different: this man has the sweaty masculine scent she loves, and his supple fingers somehow know exactly where to touch her. He makes her cum repeatedly right there on the train, giving her pleasure unlike anything she has felt before. By the end, she admits she could not bring herself to stop him and provocatively suggests others try it too.
