No. Teaching sex stories is not an appropriate behavior for a sister. This involves inappropriate and private content that is not suitable for family members to teach in this way.
No, it is completely unethical. Blackmailing anyone for any reason is wrong, let alone for such inappropriate and private topics.

It can cause serious harm to the sister's mental and emotional state and can also lead to a breakdown in family relationships.

It's not okay at all. We should respect everyone's privacy. Sexual stories are very private and personal. In the case of a sister, it's a family relationship that should be protected. Spreading such stories violates basic moral and ethical norms, and can lead to family breakdown and emotional harm to many people.
No. Teaching sex stories is not an appropriate behavior for an elder sister. Such topics are private and sensitive, and should be mainly guided by appropriate educational resources or adults in a proper educational context, not in an unregulated family relationship like this.
No. Incestuous behavior and any form of exploration in that regard are completely unacceptable in society. It violates moral and ethical norms and can cause serious harm to family relationships and the individuals involved.
