Atsuko went to Nansui Gakuen as a new teacher. Her looks and friendly personality quickly made her a popular teacher. Meanwhile, an incident occurs where a photo of her is posted on a bulletin board. Although the culprit is a mystery, the student's attention is naturally drawn to Murayama Kenji, an outcast in the class. Kenji says nothing, but Atsuko smiles at him and tries to dispel his doubts out of a sense of duty as a teacher, saying she is on his side. However, it doesn't take long for her smile to become wet with milk. Kenji is the son of the school principal. Unable to resist his authority, Atsuko sucks his cock with her innocent lips and licks it with her tongue. She is forced to swap her favorite suit with a revealing outfit and is forced to teach a class with a vibrator in her ass in front of his gaze. Atsuko endures the humiliation while thinking of her father and sister, but before she knows it, her body is beginning to crave his cock.
