Definitely not. These kinds of stories are not suitable for public or private sharing. They are not in line with good taste and can make people uncomfortable. Moreover, it might also be considered as vulgar content in many cultures.
Well, we could talk about a story where Khala (aunt) takes her niece/nephew on a wonderful adventure. For example, Khala takes the child to a beautiful park. They explore the different areas of the park, like the flower garden where they see all kinds of colorful and fragrant flowers. They also go to the small lake in the park and feed the ducks. It's a really heart - warming and positive family - related story.
Maybe a story about Didi could be that Didi and I were volunteering at an animal shelter. We took care of the cute puppies and kittens, feeding them and cleaning their cages. It was a very fulfilling experience with Didi.
One can go shopping with an aunt. It's a great opportunity to bond while looking for new clothes or accessories. An aunt might have different fashion tastes, and sharing opinions can be really fun.
Sharing such stories is completely inappropriate. These types of stories involve private and often inappropriate sexual content which violates moral and ethical boundaries in most societies.
No. In a civilized society, we should promote positive values, and stories with sexual content are not in line with the values we should uphold in public communication.
