Niizuma Yuka plays a female teacher who is well-known in the school for her beauty and has a happy relationship with her husband. However, a delinquent student in her class threatens to destroy her peace. He finds out her weakness and forces her to perform unholy services in the classroom after school. She is humiliated as she is pressed against the blackboard and her skirt is lifted up. Every time the delinquent student's rough thrusts hit her deepest parts, her pride as a teacher sinks into the mire of pleasure. Although she loves her husband, when she realizes her own masochism, unable to escape his young, rough cock, the light fades from her eyes and only lustful ecstasy remains. This is the culmination of NTR, as a beloved wife is filled with her student's semen.
