I deliberately expose my pregnant belly, which grows every day, on a crowded train / 日々大きくなる妊娠腹を満員電車でわざと露出させて生活します

A friend asked me out by dressing 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.
