NTR Kishi 01 | NTR騎士 第1話 幼馴染は女騎士 魔術に墜ちる巨乳教官

Korius attends a training academy as a knight in training. The new instructor who appears before him is his childhood friend, Aertel.

"It's been a long time, Korius."

Korius rejoices at reuniting with Aertel, who has grown beautiful and strong. However, Aertel quickly incurs the resentment of a fellow instructor, Locke, soon after her assignment. Aertel falls victim to Locke's machinations to ensnare her, and her mental freedom is taken away. Her ample breasts are ravaged and her purity is stolen right before the eyes of her childhood friend. Locke's heinous acts escalate, and Aertel, while unconscious, has her body, trained as a female knight, educated into a mere female.

The joy of reunion is the beginning of a nightmare. A proud knight, through a despicable trap, has her soul rewritten (NTRed).
