I'm not sure specifically what this story is about without more context. It could potentially be a very serious and inappropriate situation if taken literally, but it might also be a figure of speech in some strange or miscommunicated story.
It depends on the type of stories. In some melodramatic or soap - opera - like stories, this might be a more common trope to create drama and conflict. But in general, in real - life - inspired or positive - themed stories, it's not so typical. It goes against the values of friendship and marriage.
It could mean that a man entered the club where his wife was. For example, he was looking for her in the club and finally 'came inside' the club where she was.
One possible interpretation could be that in a story, a male character entered a place where the speaker's wife was located. For example, he came inside the house where the wife was.
In most cases, it's not an appropriate concept. The idea of 'coming inside' has connotations that are not suitable for a respectful relationship, whether it's in a club or any other setting. It gives an impression of overstepping boundaries rather than something positive.
The title 'Seduce by Friends: A Dominatrix Sister Story' gives an impression of a rather unique and perhaps controversial plot. It could be that the friends are in some way influenced or attracted by the sister's dominant nature. This could lead to a series of events that test the boundaries of friendship and family relationships. For example, the sister might use her dominance to manipulate the friends, or the friends might try to use the sister's power for their own gains, creating a web of complicated interactions.
It could be a story about how your big brother entered your life in a significant way. Maybe he moved into your room when you were young, and from that moment, he became a constant presence, sharing his experiences, protecting you, and creating memories together.
One possibility is that it's about sharing a secret place. Your big brother found a cool hiding spot, like a small attic in your old house, and he brought you inside. You both made it your own little world, filled with treasures you collected and stories you told each other.
Rather than sharing a story with such a negative connotation, we should encourage stories about building strong, loving and respectful relationships between spouses.
