Every time the train sways, my cock gets sandwiched against the panties of the woman in front of me. With each motion, the tip of my dick brushes closer and closer to her pussy hole—almost entering, yet never quite slipping inside. This incomplete state only heightens the excitement even more. I'd sacrifice passion, youth, emotion, my entire reputation—anything—just to feel that unbearable tension of almost penetrating her. Even without full insertion, the sensation amplifies the pleasure exponentially. Please note that due to the focus on grinding, there are relatively fewer scenes of her playing with my cock.
