Hikari-san is the charming shop girl at a small bento shop in town. She greets every customer with her energetic and cheerful smile. But unbeknownst to them, she's actually a wild and lustful woman. Her hobby is to freely devour men after closing time, either inside the shop or at their delivery addresses, making them feel energized. Today, as always, men are coming by, hoping for both a warm bento and some pleasurable sex.
