Feel-Good Magic Training 4

Every time she's intimate with her teacher, she's filled with magical power - this is how magic is produced in this world. As a young child, Lulu had her family taken away from her by a magical beast. This led to her enrolling in a magic academy, hoping to become someone who could protect others from the same fate. Upon arriving, she's greeted by Schedar, the sorcerer she admires and the one who saved her life. Thinking she had finally made the first step towards becoming a great sorcerer, she is suddenly confronted with the hidden "secret" of magic. That is... the shocking truth that a sorcerer's magic is born from pleasure! After much deliberation and seeing the state of things around her, she becomes resolute - "Please help me produce more magic!" she cries out. Joined with her professor in a passionate embrace, she is overcome with a wave of pleasure, and along with it a strength like never before. This is the story of how a young girl becomes a true sorceress.
