Tanaka Nene's H-cup big tits are the highlight of this 4-hour endurance iron-man race. The film is rich in content, with powerful tits, nipple torture, and bondage scenes, but the length of the film makes some parts feel a bit slow. Nevertheless, it is still possible to take a good look at the naked body of this sex athlete, and there are plenty of angles for tit lovers. However, there are some disappointments, such as the fact that there is only the first part of the film, and the triathlon-style costumes are missing in the second half.
