The Hojo family whose nephew Kazuya, who came to Tokyo for the entrance exam, decided to stay for a while. Maki welcomes him with a smile, but Kazuya, who has a strong sexual desire, asks her to teach him how to put on a condom instead of studying. Maki, who was originally weak against pushing, could not refuse clearly and put it on his erection cock as he was told. Kazuya, who was excited about the first rubber, could not stand it. Maki desperately persuades, but her mind and body, which are weak to push, are overwhelmed by his aggressive caresses and young and strong cocks.
