I am a high school student in a fairly wealthy family. To improve my health and avoid drowning accidents in this scorching summer, my parents hired a swimming teacher for me. She is Sakurai, with big breasts and a plump figure, as soon as I saw her I was captivated by this charm. As a handsome young man, it was not difficult for me to court a single teacher. We devoted our feelings to each other but secretly hid it from my parents. Every day after practice, in the changing room, she would reward me with affection for my efforts and to help our relationship grow stronger.
