In ancient myths from various cultures around the world, we find stories about the afterlife, the relationship between humans and the divine, and how to live a virtuous life. There is no room for such offensive 'guy sucks cock stories' as they go against the very essence of what ancient myths were created for.
I'm not aware of any positive or appropriate stories with such a vulgar concept in mainstream literature. Literature usually focuses on more positive, moral and inclusive themes.
Rather than delving into such inappropriate stories, we should encourage a society that promotes love, respect, and positive interactions within marriages. There are so many wonderful aspects of married life to focus on, like mutual support and shared dreams.

Movies usually approach interracial relationships in a more positive and respectful way. There are films that explore the connection between a black man and a white woman, but not in the offensive way the title implies. One such example could be 'Jungle Fever' which delves into the complex relationship between the two characters from different races, dealing with issues like family reactions, cultural differences, and the power of love.
