I am a high school teenager from a wealthy family. To improve my health and avoid drowning accidents during this hot summer, my parents hired a swimming instructor for me. She is Sakurai, with a big chest and a curvy body; I was captivated by her charm as soon as I saw her. Being a handsome young man, it wasn’t difficult for me to flirt with a teacher who is still single. We devoted our affection to each other while secretly hiding it from my parents. Every day after practice, in the changing room, she rewarded me with a moment of affection for my efforts, which also helped strengthen our relationship.
