No. It is completely unethical. Forcing or asking a family member, especially a sister, to be involved in creating or submitting erotic stories violates boundaries of appropriate family relationships and is a form of exploitation and abuse of the family bond.
Definitely not. It is an inappropriate and unacceptable behavior. Everyone has the right to their own privacy and freedom, and forcing someone to be involved in creating or submitting such inappropriate content is wrong on many levels. It can also lead to a breakdown in family relationships and trust.
First, you should stay calm. If it was truly an accident, have a civilized conversation with your neighbor. Explain how this made you and your wife uncomfortable. Maybe ask him to be more careful in the future and respect boundaries.
There is no logical connection between a dress accidentally ripping and erotic stories. A ripped dress can happen due to various reasons like getting caught on something, a manufacturing defect, or normal wear and tear, which have nothing to do with erotic stories.
First of all, you should sincerely apologize. Then, try to have an open conversation about boundaries and privacy. Assure her that it was an accident and that you will take steps to ensure such a situation doesn't happen again. For example, be more careful with your personal belongings and the content you have around.
You should not provide her with such inappropriate stories. Erotic stories are not suitable for sharing, especially not with a sister. You could suggest some positive and family - friendly books or stories to her instead.
Literature typically focuses on positive values and relationships. Stories with such inappropriate content are not the mainstream and are not worthy of promotion. So no.
You should immediately protect your sister. Report the person who is doing this to the authorities. It's important to make sure your sister is in a safe environment away from the person who is trying to force her.
