Having sex with an older sister is completely unethical and goes against moral and social norms in almost all cultures. Incestuous relationships are not acceptable as they can cause a great deal of emotional and psychological harm to family members and violate the basic principles of family boundaries.
In society, such a situation would be met with extreme condemnation. It can disrupt the social fabric as families are the basic units of society. The family members involved may face isolation, not only from their immediate family but also from friends and the wider community. It can also have a negative impact on the mental health of family members who are not directly involved but are affected by the knowledge of such an inappropriate relationship. And from a legal standpoint, depending on the jurisdiction, it can lead to criminal charges.
One appropriate story could be about how the wife's older sister helps the couple during their wedding preparations. She might use her experience to offer advice on choosing the right venue, the best flowers, and how to deal with family politics during the big day.
In general, it is not appropriate. Sex education is a sensitive topic, and it is better to be taught by parents or professional educators. Siblings should maintain appropriate boundaries, and this kind of teaching might cross those boundaries and make both parties feel uncomfortable.
