One negative impact could be the distortion of the brother's view on sex. Since the sister is not a professional in this area, she may convey wrong or inaccurate information. Another is that it can create an uncomfortable and inappropriate atmosphere within the family.
First, it should be made clear to her that this is inappropriate behavior. Then, ensure that proper sex education resources are provided to those who need it in a more appropriate way, such as through schools or professional educational institutions.
I recommend you to read the novel " The Twins of the Storm." This was a modern romance novel about a wealthy family. The main character was a reborn older brother who was running around with his loyal younger brother. In the novel, the older brother admonished the younger brother to do whatever he wanted, and his life might not be magnificent. If you like this type of novel, this book might suit your taste.
