My homeroom teacher, Mr. Kikuchi, was hospitalized, and a teacher named Hitomi Enjou came to my school as a temporary student. Hitomi-sensei resembled my mother who died when I was young, she was beautiful and sexy, and I started following Hitomi-sensei with my eyes. After school one day, by chance, I and Hitomi-sensei were alone in the classroom, and the teacher's hand suddenly touched my cheek. The touch of the finger felt warm like I felt a long time ago, and I had no choice but to entrust myself to Hitomi-sensei.
