The little lady having no prior knowledge of sexual matters is given a naughty lesson.

A college student spends his first summer in the countryside. While having difficulty looking for a suitable part-time job in the neighbourhood, he discovers a private tutor advertisement. He quickly gets accepted when he gives a call asking about the position.

To his surprise, he is welcomed into a splendid spacious home, where he begins to tutor a lovely little lady. They get along splendidly as the days pass. Eyeing on her bosom, coming in contact, and finally giving the long-awaited kiss...

"Senpai, I want to learn about sex education too!"

The routine study sessions are ignored, and the naughty lessons are born.
