Saki started going to the gym to maintain her health and beauty two months ago. She was enjoying the thrill of sports. One day, she was advised to swim in the pool at the gym. Saki, who wasn't good at swimming, was reluctant but was told that it was the most efficient way to train her core muscles and that she would surely improve. So, she tried swimming, but it turned out to be the beginning of a nightmare. She fell into the mad trap of a group of perverted swimmers, got raped while wearing a competitive swimsuit, and became a fallen big-breasted housewife.
