No. Such content is vulgar and inappropriate for public sharing. It violates moral and ethical norms and may also be against the rules of many platforms.
Definitely not. Workplace is a place for professional interaction. Sharing sexual stories, no matter what form, is disrespectful to others and can lead to various problems, like sexual harassment claims or a negative impact on team morale. We should focus on work - related matters instead.
I've not come across such a story. It could be a regional or personal story that hasn't spread widely. Maybe it was made up by someone in a prison setting or by those who have an interest in prison - related fictional tales, but that's just a guess.
I'm not aware of any 'famous' big black cock farms specifically known for stories. Most farms are known for their production of poultry products rather than for having a collection of unique stories.
Sharing or seeking stories with such racially and inappropriately sexualized content is not acceptable. We should focus on positive, inclusive and respectful stories that promote equality and good values among all people regardless of race or gender.
