Since I don't know exactly what'mom sis bata stories' mean, it could be that 'bata' is a person, a place or an event. If it's a person, the stories might be about the relationship between a mom, a sister and this 'bata' person. For example, how they helped each other, or had some conflicts and then resolved them. If 'bata' is a place, the stories could be about their experiences in that place.
One common 'mom catches son and sis' story could be when they are up to some innocent mischief like trying to bake a surprise cake for her without permission and making a huge mess in the kitchen. Mom comes home early and catches them covered in flour and with ingredients all over the place.
I'm afraid I can't share such stories since I'm not familiar with the concept of'mom sis bata stories'. It could be very specific to a certain family or community.
Typically, 'taboo mom and sis stories' are not designed to convey positive moral lessons. These stories often involve abnormal or unethical relationships which are frowned upon in society. But hypothetically, if we were to look for one, it might be that in the face of difficult family situations, communication is key. But this is really just trying to find something good in a generally bad concept.
No, it is completely unethical. Such themes involve incestuous relationships which go against basic moral and ethical values in society. Incest is not only considered taboo in most cultures but also can cause serious harm to family relationships and the psychological well - being of those involved.
Once upon a time, there was a granny who lived with her daughter - in - law and grandson. The granny was very kind and full of wisdom. One day, the son got into trouble at school. His mom was so worried but didn't know how to deal with it. Then the granny sat down with the mom and son, and told them about her own experiences when she was young. She said that facing difficulties was normal, but how you dealt with them was important. She gave the son some good advice, like being honest and trying his best to make up for his mistakes. And from that day on, the son listened to his granny more and became a better person.
Sharing or giving Viagra to a son by a mother is extremely inappropriate and unethical behavior. There should not be such real stories in a normal and healthy family or social environment. Viagra is a medication for a specific adult use, and this situation violates basic family ethics and medical ethics.
Maybe the son shares fictional stories that involve characters' facial expressions. For example, he might tell about a character in a book who had a very surprised face when they saw a magical creature. It could also be stories where the description of facial features plays an important role in the plot, like a detective noticing the nervous twitch on a suspect's face.
