I deliberately expose my pregnant belly, which grows every day, on a crowded train

A friend asked me out on a date dressed a little more grown up. I wore revealing clothes and eye-catching makeup that I had never worn before. I wasn't surprised to find the men around me looking at me.

When she got off the last train, which was already running late, a man approached her from behind, led her into an empty public toilet and raped her.
Later she discovers she is pregnant and, to lure out her rapist, decides to ride the train in revealing clothing.
