Incompetent Magic Teacher Charmes Life Reversal -Vengeful Breasts H-

This is the magic academy of a certain country, Paiots Magic Academy... The incompetent magic teacher, Charms, spends his days being scorned by his students once again. "Am I going to end my life like this... not only failing to accomplish anything, but being ridiculed by people forever...?" As he was lost in thought, he noticed a hidden room behind a bookshelf... As he went further, he found a suspicious room with a suspicious book... Is this... a forbidden book containing ancient taboo magic...?? Hesitantly, he reached for the forbidden book, and a sealed succubus jumped out! Spoiler Huh?? I felt a talent for charm magic, but it's so dull... and a man?? I thought it would be a cute girl with big breasts?? But... hehe, that hatred, that immense suppressed libido... I can feel the potential for all sorts of forbidden magic, not just charm! This encounter will drastically change Charms' life...
