A busty college girl who has been made to cum with her deep-school technique

Yuka, a serious female college student, is not satisfied with sex, but events occur that destroy Yuka's values ​​about sex. Akikawa, my father's friend, who was a private tutor when he was little, gets drunk and attacks Yuka, who has grown into an adult body. Yuka was confused, but halfway through, she was melted both her body and mind by the skilled techniques of a middle-aged man whom she had never felt with her boyfriend... From that day on, he became a very sensitive constitution that made him feel aroused just by seeing an old man.
