Another reason might be related to protection. Panties can act as a sort of shield. For instance, if I'm playing around and might accidentally sit on a rough or dirty surface, panties can provide some protection. Mom is always thinking about my well - being in this way.
One possible story could be that mom makes me wear panties because she thinks they are more hygienic. For example, when I'm going for a long day out, she insists that panties made of breathable fabric can keep me comfortable and clean.
A common reason is for medical needs. If a child has bladder control problems, diapers are a must. For example, some kids have weak bladder muscles and wearing diapers helps them stay clean and dry.
It could potentially be part of some very dark and inappropriate power - play in certain extreme and unethical fictional stories. However, this is not acceptable behavior in real life.
Maybe the mom is a fashion designer or has a passion for fashion and wants to experiment with different looks on her son, not really in a malicious way but more out of creative exploration. Also, it could be part of a family bet or a fun challenge within the family to see how the son would look and act in girls' clothes.
In some fictional tales, the wife might not wear panties as a result of a magical or supernatural influence. For example, if there is a spell or curse that makes her feel uncomfortable wearing them. Another aspect could be that she is trying to make a statement about body acceptance and comfort. By not wearing panties, she is showing that she is at ease with her body and doesn't need to follow the typical undergarment - wearing rules. Also, in a story about a character's journey of self - discovery, this could be a small part of her new - found boldness and independence.
One reason could be for comical purposes. The wife might think it's really funny to see her husband in panties and wants to create a light - hearted moment in their relationship.
In the story, she could be making a statement about modern relationships. She wants to be completely open and honest with her husband about her body and her choices. By not wearing panties, she is showing that she trusts him completely and that there are no secrets between them when it comes to her physical self.
It's a rather personal choice. Some might argue it's inappropriate in public settings as it goes against social norms of modesty. But in a private, comfortable home environment, it could be about personal comfort or a form of sexual liberation within the relationship. However, in public, it can make others uncomfortable and may violate certain decency laws in some places.
It's not a simple matter of being appropriate or not. In different cultures, the perception varies. In some Western cultures that are more liberal, it might be seen as a bit of a risque but not completely unacceptable behavior in certain private situations. But in more conservative cultures, it would be considered highly inappropriate. As for reasons, it could be related to body comfort. Maybe she finds traditional undergarments restrictive and just wants to feel free.
One reason could be a medical condition. For example, if someone has a skin allergy to the fabric of panties, it would make wearing them uncomfortable or even painful. So in the story, the character might be dealing with this itchy rash every time they try to wear panties and thus can't do it.
