There shouldn't be. Our society values healthy, consensual and proper relationships. A story like this goes against the basic values of respect, propriety and legality in human relationships.
A story about an older woman mentoring her son's friend in a positive way, like helping him with his career choices or teaching him a valuable life skill.
A woman had a friend whose son was extremely talented in painting. His name was David. The woman often visited her friend's house to see David's latest works. One time, David was preparing for an important art competition. The woman encouraged him and helped him to find some unique inspiration from nature. In the end, David created a masterpiece and won the competition.
A woman knew a friend who had a son. The son was a bookworm. One day, the woman visited her friend and saw the son completely engrossed in a thick novel. She asked him about it, and he started to tell her all about the story, the characters, and the hidden meanings. The woman was amazed by his knowledge and passion for reading. They then started a small book club together just for the two of them.
In most cases, it's unethical. A best friend relationship is based on trust, mutual respect, and non - sexual affection. Once sexual activities like a blowjob are involved, it can change the dynamic completely. For example, if one person has different expectations afterwards, it can create a rift. Also, it may make other friends uncomfortable if they find out, and can even lead to the breakdown of the friendship group.
It could end with the married woman and her son's friend going their separate ways amicably. Maybe the son's friend moves away for college or a job opportunity, and they part as good friends.
Perhaps the story involves the married woman noticing that her son's friend is going through a tough time at home or school. She decides to offer support and guidance, which in turn leads to a series of events that change both of their lives. For example, she might help him with his college applications and in the process, he helps her rediscover her long - lost passion for writing.
He should communicate clearly. He could directly tell the married woman that her behavior is inappropriate and making him uncomfortable. For example, say something like 'I respect you as my friend's mother, but your actions are not okay'.
