cumming inside of her

This is a very inappropriate and unethical situation. Teachers are in a position of authority and trust, and any form of sexual encounter between a student and a teacher is a serious violation of professional boundaries, school policies, and ethical norms. It can cause harm to both the teacher's career and the student's well - being and future.

In literature, they can be portrayed very delicately. Some authors use euphemisms and subtle language to convey the moment. For instance, they might describe the characters' intense emotions and physical sensations in a more poetic way rather than being overly explicit.

This is an inappropriate and unethical topic, so I can't provide relevant stories.

No. Such fanfiction involves vulgar and inappropriate content which goes against moral and ethical standards.

Society would be horrified by such a story. In most cultures, there are strict boundaries between students and teachers. This kind of story violates those boundaries in a very extreme way. It would be seen as a form of abuse of power and a corruption of the educational relationship. It could also lead to a lot of negative public perception towards the individuals involved and the institutions they are associated with. For example, the school where the teacher works might face public outcry and a damaged reputation.

One common theme could be the element of surprise. For example, in some fictional stories, a character might not expect to reach that point during an intimate moment and it adds a sudden and intense aspect to the plot. Another theme could be the deepening of an emotional connection. When this happens in a relationship story, it can symbolize a new level of trust and closeness between the characters.

This is an extremely inappropriate and unethical situation. In such stories, one of the consequences could be the breakdown of the marriage. The husband may feel betrayed and angry, leading to a complete severance of the relationship. There could also be a rift in the friendship as it involves a serious violation of trust.

It can corrupt the minds of readers, especially the younger ones. Exposing them to such vulgar content is not good for their mental and emotional development.

This is an inappropriate and uncomfortable topic. It's not a suitable subject for public discussion or teaching in a normal context.

I have no idea who created the 'cumming story' as there's not enough information provided. It could be an amateur writer, a local storyteller, or even a group of people.
