A serious and innocent girl's trouble

Marinaka, the girl of the age, was troubled without being able to follow all the class topics of her classmates. On such a day, I visited my teacher's home on a holiday to teach my teacher about sex. However, she was a good quality teacher who was familiar with the customs every week, and she first paid her to the teacher's home to go to the manners she had reserved, but she was so obstinate that she took advantage of her curiosity and played the body of the development process. Marinaka also accepts the teacher really, and the body is gradually ruled.
