BM/WF (Black Male / White Female) Cuckold Interracial Breeding Sex Erotica
 

I'm looking for recommendations for BM/WW "Black Man / White Woman" adult literature or erotica that includes the following themes:

• A relationship involving a white woman, her white male partner, and a black male lover of hers
• Pregnancy resulting from the relationship with the black lover
• Exploration of complex emotions and dynamics in this situation

Any book or story recommendations with these exact elements? Bonus for detailed scenes and emotional drama. :p
