These two busty sisters are active in badminton doubles. Their looks and talent make them a strong contender for a medal at the world championships. As a result, they're frequently featured in the media, appearing on TV and elsewhere, and their popularity is skyrocketing! However, a video of the younger sister's adulterous act is sent to their sponsor, enraging them. The two are called in to apologize, but... The sponsor is a perverted, bald, middle-aged man. He exploits their weaknesses and sexually harasses them! He fondles and licks their gigantic breasts, doing whatever he wants! He even forces them to have sex with other employees. The older sister defends her younger sister, but she's also forced into lesbian play, made to orgasm with oil toys, and ends up in a gangbang where she swallows semen! She even apologizes with her body.
