Mai is a former water polo player who has trained hard and achieved excellent results in many competitions. Even though she is retired, her well-trained body and firm, big-breasted body are just the right amount of meat, making her the kind of person you want to devour. It seems that her libido increases when she exercises, and she would invite male athletes and have sex with them during training camp. However, it seems that she has never cum, so we decided to make her cum for the first time in her life, and as much as she could.
