What are the possible motives behind blackmail into a 3some fantasy story?

Financial motives can also be there. If the wife discovers that the husband has some hidden money or is involved in some financial wrongdoings, she might blackmail him to get a share of the money or to make him correct his financial behavior. For instance, she could threaten to expose his tax evasion to the authorities if he doesn't give her a certain amount of money for household needs.

One possible motive could be financial gain. The blackmailer might think that by having this kind of control over the CEO, they can extort large sums of money. Another could be revenge. Maybe the blackmailer has some personal vendetta against the CEO or the company and uses this extreme method to cause damage.

Well, motives in adult blackmail can be diverse. Greed is a significant one. The blackmailer sees an opportunity to make easy money from the victim's fear of exposure. There could also be a psychological motive where the blackmailer has some sort of personality disorder or just enjoys causing distress to others. In some cases, it might be related to a competitive situation, like in a business or personal rivalry, where one person tries to gain an upper hand by blackmailing the other.

One possible motive could be financial need. Just like in the story of Mrs. Thompson, she might be in a difficult financial situation and see blackmail as a way to get quick money. Another motive could be revenge. If an older woman has been wronged by someone in the past and she discovers a secret of that person, she might use blackmail as a form of revenge.

One possible motive could be revenge. The student might have been bullied or unfairly treated by the teachers and sees blackmail as a way to get back at them.

Money is a primary motive. Crime lords use extortion and blackmail to amass wealth quickly. They target businesses, for example, demanding protection money, knowing that businesses often prefer to pay rather than face potential harm to their property or employees.

Jealousy might be a motive. Maybe the coach was never as successful as the jock in his own high school days. So, he blackmails the jock to make him feel superior. He could force the jock to miss important games or not get the proper training, just out of spite.

Another possible motive is revenge. Maybe the miss teacher once rejected the blackmailer's romantic advances in the past. In this fantasy story, the blackmailer could be a dark wizard who has been nursing this grudge for a long time. He decides to blackmail her by threatening to expose a secret she has been keeping, such as she has a hidden family of demons which in the world of the story would be a great scandal.

Perhaps he has a mental disorder that makes him unable to control his violent urges. He might not even fully understand his own motives, just acting on some dark impulse within him. Another possibility is that he is being controlled by some external force, like in a horror story where a curse or an evil entity is making him commit the slaughters.

One possible motive could be for a prank. People might want to give their friends or family a big scare and then have a good laugh about it later. For example, like the stories where friends plan a fake abduction to surprise the victim with a party or some other fun event.
