[Amamiya Mizuki] Genkaku Kijo Kyoushi NTR Manga [Satoru]

A strict schoolteacher with a beauty mark beneath her eye transforms from a harsh disciplinarian who calls her student 'useless' into a panting, lingerie-clad supplicant begging to be claimed. With her student pinning her down, she offers herself with desperate apologies while their principal walks in on the humiliation—a betrayal that only fuels her cravings. The climactic finish soaks her thighs as she swears she'll never let him return her to her old life.
