The reason a female student is forced to stay behind every day hides a secret motive: being alone with her teacher. By giving special treatment to the unpopular girl, the teacher gradually seeks to monopolize her heart. An intense kiss becomes the turning point that deepens their relationship. Unable to suppress his desire, the teacher grows aroused by the softness of her young body. Drawn into a forbidden relationship, the two are driven by uncontrollable impulses, constantly fearing exposure, yet drowning in illicit pleasure. The touch of their lips and tongues brings a sweet, sinful experience filled with taboo desire.
