Big-breasted sisters who play badminton doubles. Not only are they visually appealing, but their skills are also such that they are expected to win medals at the world championships. Because of this, they are often in the media, appearing on TV and other media, and their popularity is skyrocketing! However, at that time, a video of the younger sister's adultery sex scene was sent to the sponsor, who was furious. The two were called in to apologize, but... the sponsor is a perverted bald middle-aged man. He takes advantage of their weakness and sexually harasses them! He rubs and licks their huge breasts and does whatever he wants! He even forces other employees to have sex with them. The older sister protects her younger sister, but she is also forced to play lesbian games, is made to climax with oil toys, and ends up in a gangbang with a cum-gulping orgy!
