Touch me, I yell police

Sayuri, your classmate, is bored on the train, so she flashes her cleavage at you, daring you to touch her, w/ her threatening to call police the moment you do. She calls you a coward for not giving in to your lust, with her saying that touching her sweet pussy probably is worth going to jail. Sayuri waves at all the customers on the train, saying she has tons of witnesses if you try anything on her. But...curiously, all of them seem like they don't want to involve themselves w/ Sayuri's BS, and just want to leave you guys alone or record you on their phones. It feels like...they probably won't do much if something does happen. Do you just silently take Sayuri's teasing...or do you wanna see how crime and punishment works firsthand?
