No. This is a very abnormal and unethical plot that is not common in mainstream literature. Most literature focuses on positive values and healthy relationships.
Well, if we look at it from a literal sense, it seems like it's about a mother engaging in inappropriate behavior towards her daughter in public according to some stories. However, this goes against all moral and ethical norms, and such stories are likely to be part of some dark or deviant fictional works.
No. Teaching sex stories to a daughter by a mom is highly inappropriate. Sex education should be done in an age - appropriate, scientific and professional way, not through 'stories' in a family setting which can be very confusing and improper for a child.
There could be a story where the daughter tries to get her mom to take a vacation. She shows her mom pictures of beautiful places, talks about how much they need a break, and uses her affectionate ways to persuade her mom. This is a positive form of getting her mom to do something good for both of them without any inappropriate undertones.
Sharing such stories is completely inappropriate and unethical. These are family relationships that should be respected and protected, and any form of sexual content related to family members is unacceptable in a civilized society.
Perhaps in a story about a family with a cultural background where there are specific traditions of daughters showing respect and love to their mothers in a very demonstrative way. This could be misconstrued as'seduction' but is actually just a deep - rooted cultural expression. For instance, in some cultures, daughters may perform special dances or present handmade gifts to their mothers in a very elaborate and affectionate manner.
One negative impact is that it can cause confusion. A child may not be ready to understand sexual concepts in the form of stories from a mother. It can also make the child feel embarrassed or ashamed.
