SONE-940 On the seventh day of secretly adding an aphrodisiac to his homeroom teacher, a young female teacher close in age, she had transformed into a lustful woman who kept wanting her student’s attention. Nanatsumori Riri

Riri is a beautiful and popular female teacher who is admired by her students. In her class were two male students who excelled in chemistry. The potion they created in the classroom was a very powerful formula that made people obsessed with desire and left them feeling intensely aroused. They did not realize it yet, but it was a groundbreaking stimulant.

After they carelessly gave it to Riri as a joke, a few days later she collapsed in the classroom in an emergency. When they hurried her to the infirmary, Riri was dazed but still flushed and overheated. Seeing her like that excited the students, and they began releasing their youthful desires through intimate encounters with her.

As this became a regular pattern, Riri, with only hazy memories, visited the science club room and discovered the formula for the potion, then called the students back to the classroom. The mistakes made in their school days by the chemists who would later become famous were an emotional and provocative chapter of youth.
