On a crowded commuter train, a married woman's honey-like waist and soft yet toned figure caught everyone's attention. Surrounded by men who couldn't take their eyes off her, they began touching her without hesitation, making it impossible to look away. When the train reached the station, she stepped off with a slight sway in her step. Watching her, I decided to follow. She seemed to work as a librarian. As she stood selecting books in front of a shelf, I stared at her back. Suddenly, a man who appeared to be her superior approached and said something. Apologizing, she was led into another room. Once again, I secretly trailed behind. The man stripped off his underwear, and right there, she offered her body, beginning to suck his penis. Her expression carried a strange sadness, yet also a sense of pure devotion. Panicking, I quickly hid behind the bookshelf. After a while, she turned, looked straight at me, and smiled. "Hey, I know you were watching earlier..." Her words sent a tightening sensation through my chest.
