Atonement of the Lustful Mother #2 (TYPE.90)

After a serious accident, Nagumo Kazuki returns to school only to fall back under the sadistic control of Ayumi, an older nurse who rapes him in the restroom and blackmails him into total submission. She drags him into a storage room for relentless sexual domination, mocking his involuntary arousal and forcing him to degrade himself until his will is broken. The school officially appoints her as his constant monitor, allowing her to maintain a professional facade while she continues to torment him in private, solidifying her absolute control over every aspect of his life.
