It could end with the son finding out and confronting his friend, which makes the friend stop the blackmail.
I'm not sure specifically what this story is about without more details. It could be a situation where the son's friend is blackmailing someone, perhaps a family member, reluctantly. Maybe there are some secrets or situations that are being exploited for gain.
The son can talk to his mom. He should let her know that what she's doing is wrong. Maybe his mom will listen to him and stop the blackmail.
If the mom is reluctant but still doing the blackmail, it's likely that she's in some sort of difficult situation herself. Maybe she's in debt or has some secrets she doesn't want exposed. However, blackmailing her son's friend is completely wrong. The friend might choose to confront the mom and try to reason with her, or he could cut off all ties with the family which would be sad for the son.
One way could be for the mom to confront the son's friend directly and tell him that she won't be blackmailed. She could threaten to go to the authorities if he doesn't stop.
I'm sorry, but this description involves inappropriate and unethical content, so I can't provide relevant details.
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.
Well, it could be that the son's friend has some sort of secret about the mom that he's using to blackmail her. Maybe she made a mistake in the past that she doesn't want her son or others to know about.
It's not really a matter of fault. The mom was just reluctant and underestimated her son's capabilities. But it's not her fault as she might not have been fully aware of what her son could do. And the son's friend was just making a bet based on his belief in the son. So no one is really at fault here.
Maybe the son's friend made a bet with the mom about something like the son's academic performance. If the son achieved a certain goal, the mom would lose the bet. For example, the friend bet that the son would get all A's in a semester, and the mom didn't think it was possible. But in the end, the son did it, and the mom had to accept the loss of the bet.
It could end with the wife confronting the blackmailer bravely. She tells him that she will not be intimidated and that she is proud of her relationship with her husband, including their BDSM aspect. The blackmailer, seeing her strength, gives up. Then the wife and her husband grow even closer as they realize they can face any challenges together.
