The boss knows that the secretary has a lover and the ending

Natsu, who is alert and reserved, has a shy personality that cannot be refused. One day, he confessed to Sato, who was in the same department, and they started dating. Natsu, who usually wears plain glasses and has messy hair, is noticed by his manager when he sees Natsu's skin tone, and the excessive sexual harassment begins the next day. Natsu, who couldn't refuse, gradually grew breasts and immediately fell into pleasure as she was trained on her constitution.
