It could mean that the boss has some influence or control over stories related to you and your wife. Maybe he has a say in how certain events or situations involving you two are presented or remembered.
It might also suggest that there are stories about how the boss has an impact on your relationship with your wife. This could be in terms of work - life balance, like if the boss gives you excessive work that affects your time with your wife, and these situations have become stories among your colleagues or in your own mind.
It could mean that your friend has some stories or experiences related to your wife. Maybe they've shared some memories together or have anecdotes about her.
Suppose the boss has a habit of calling you during your family time, and your wife gets frustrated about it. The repeated occurrences of this and the resulting tension in your relationship can be a 'boss ownes me and my wife stories'. It's about how the boss's actions are influencing the dynamics between you and your wife.
The statement 'I ducked my wife's boss - True story' is rather ambiguous. 'Ducked' might imply that the person took steps to avoid coming into contact with the boss. It could be that the boss had a reputation for being difficult or unkind. Maybe the speaker had overheard something about the boss that made them want to stay away. Or perhaps there was a personal issue between the speaker and the boss that was related to the wife's work, like the boss treating the wife unfairly and the speaker was afraid of getting into a confrontation if they were around the boss.
If the stories are positive and harmless, you can just let it be. But if it makes you uncomfortable, you might gently remind your friend that your wife is your partner and while they can share memories, the concept of 'owning' stories might be a bit odd. You could say something like 'I'm glad you have memories with my wife, but she's my family and we should respect boundaries.'
The phrase 'owned stories' is rather strange. It might be a creative way of saying that your wife has stories that are unique to her, perhaps like family stories that she has inherited or personal adventures that she has ownership over in the sense that they are hers to share or keep.
It could mean that he had a strong influence or control over the stories related to one's wife. Maybe he was always the central figure or had a powerful say in how the stories about the wife were told.
I'm not entirely sure what this phrase specifically means as 'cum junkie' is a rather vulgar and inappropriate term. However, if we break it down, it seems to be some sort of statement about a person's wife having an excessive or abnormal attraction, which is not a proper or respectful way to describe someone.
She may be using these rough stories as a way to get a reaction from you. Maybe she feels that normal, tame stories don't get your attention as much. However, it's important to communicate to her that this isn't the best way to engage you.
It could mean that she exchanged stories with someone. Maybe she shared some experiences or anecdotes with friends, family members or neighbors. For example, she might have told a friend about a funny incident that happened at work, and in return, the friend shared a story from their own life.
A 'cuckold' usually refers to a man whose wife is unfaithful. So'my wife is my cuckold story' might imply that the story of their relationship is centered around the idea of the wife being unfaithful, or perhaps the man's perception of it, but it's a very strange and ungrammatical way of expressing it.
