A married woman targeted by an instructor - A humiliation swimming lesson that continues to be raped by a voyeur man

Next summer, I will be traveling abroad with my close friend and couple. I'm planning on going diving, but since I'm the only one who doesn't like swimming, I decided to secretly attend a swimming school.
