First of all, it's important to recognize that this is not normal behavior. You might want to distance yourself from such conversations as much as possible. If it continues, you could consider reaching out to a local child protection agency. They are trained to handle situations where boundaries are being crossed in a family environment.
This is an extremely inappropriate situation. You should immediately talk to a trusted adult like a school counselor or another family member who is more appropriate and can help you deal with this uncomfortable situation.
This is a very complex and uncomfortable situation. Such topics are private and not suitable for a mother - child communication in this way. You can write her a letter if you find it hard to talk face - face. In the letter, express your discomfort and confusion, and emphasize that you need a more positive and healthy communication content, such as sharing about daily life, study, dreams, etc.
You should firmly but politely tell your mother that this makes you uncomfortable and that such topics are not appropriate for her to share with you. You can also seek advice from another trusted adult, like a grandparent or a family friend, who might be able to talk to your mother about the inappropriateness of this.
Respect her wishes for now. She might have her reasons. Maybe she's worried about the influence on you. Try to focus on other types of stories.
This is not okay at all. In a healthy family environment, parents should focus on teaching their children positive values, good behavior, and general knowledge suitable for their age. Sex stories are not part of the appropriate knowledge transfer from a mother to a child. It can make the child feel awkward, and it may also cross the line of moral and ethical norms in family relationships.
You should firmly tell her that this makes you uncomfortable and that such content is not suitable for sharing.

Tell your mom not to respond to the blackmailer at all. Keep any evidence if there is any, like messages or emails. You can also seek legal advice. Maybe consult a lawyer who can guide you on how to handle the situation legally and protect your mom's rights and reputation.
Talk to another trusted adult, like a father, grandparent, or teacher. They can help you deal with this situation. Also, you can try to have an open and honest conversation with your mom about how those stories make you feel uncomfortable.
The best thing to do is to pretend you didn't hear it. It's a private matter and you should respect her privacy. Just keep it to yourself and try not to think about it too much.
