I'm not sure what specific "black cock regret story" you are referring to. It could be a very personal or regional story. Without more context, it's difficult to share a relevant one.
Another theme might be misunderstanding. Perhaps someone misunderstood the significance of the black cock in a cultural or traditional sense. They didn't treat it properly and later realized their mistake and regretted it. In some cultures, black cocks may have symbolic meanings that if not respected, can lead to feelings of regret.
Maybe the husband had a fantasy of having a huge cocker spaniel (cock as part of the breed name). He thought he could handle a big, energetic dog. But when he actually got one, it turned out the dog was too much for him. It chewed up all his furniture, dug holes in the garden, and he just couldn't train it properly. His 'huge cock' (cocker spaniel) fantasy went all wrong.
The title is really unclear. It seems to be about a husband and a sexual fantasy that backfires. But the term 'black coxk' is really strange. Maybe it was a typo. Without proper correction, it's hard to make real sense of it. It could potentially be about a story where a husband's sexual - related fantasy has an unexpected and not - so - good outcome, but that's just a very rough guess.
Well, perhaps it's a story where someone has a recurring nightmare about a black cock. In the nightmare, the black cock might be associated with bad omens. For example, every time it crows, something bad starts to happen in the dream world. It could be that the sky turns dark, or there are strange noises, and the person in the dream is constantly trying to escape from this situation related to the black cock.
The husband had a fantasy of getting a huge St. Bernard dog. He always thought they were majestic and friendly. He finally got one, but his small apartment was not suitable for such a large pet. The dog had no space to move around comfortably, and it kept bumping into things and knocking over furniture. His dream of having this 'huge cock' (referring to the big dog) turned out to be a disaster.
