Luring a naive girl named Hina-chan into the mirrored train set-up, claiming to teach her how to fend off gropers, they proceed to exploit her tight little body, calling it a "re-enactment of harassment."

Before she knows it, her pussy is soaking wet, and they just slide their cock in raw and deep!
