JUQ-259 Teach my grandson how to be an adult.

The Hojo family has a grandson, Kazuya, who came to Tokyo to take an entrance exam and decided to stay for a while. Maki welcomed him with a smile, but Kazuya, who had a strong sexual desire, asked her to teach him how to put on a condom instead of studying. Maki, who was initially very weak in terms of pushing, couldn't clearly refuse and placed it on his erect penis as instructed. Kazuya, very excited about the first rubber, couldn't hold back. Maki desperately tried to persuade him, but her weak mind and body, unable to push, were overwhelmed by his aggressive caresses and his young, strong manhood.
