A friend's son was struggling to focus on his studies, so his father hired his acquaintance's wife, Marina, as a private tutor. Marina was a beautiful and cultured woman, but her unexpected appearance—extra large breasts and glasses—made the son instantly fall for her. Instead of studying, he began trying to grope and touch her body. Seeing his lack of progress, Marina decided to take a more provocative approach, using erotic lessons to boost his academic performance. An intense story unfolds between Marina and the friend's son, where learning and desire collide.
