Ms. Kasumi, who was blackmailed by a sneaky janitor, forced into a physical relationship, and completely manipulated. The man's demands escalated, starting to train her within the school. Forced to drink semen, swallow urine, have unprotected sex with creampie, restrained and forced to orgasm, among other things, in a debauched training session, the true masochistic nature of the once earnest Ms. Kasumi awakened. Abandoning her teacher's pride, she let saliva and male fluids flow freely within the sacred school, falling into a depraved hole begging for more.
