Screaming birds sound an awful lot like singing (слэш)

Lord Abraxas Malfoy weds his seventeen year-old omega son to Lord Cygnus Black, but after enduring five years in a dreadful marriage, Lucius has yet to give his lord husband a male heir.
Lord Black has every right to have the marriage dissolved if no child is conceived. But who would want to wed an omega, no matter how noble of blood, if the omega is no longer pure? If he has not been able to birth a child in five years. Lord Malfoy would disown his son after such a disgrace.
Lucius envisions a future in a seedy whorehouse, the only likely outcome after his husband’s dismissal, and makes a desperate decision. He will have a child. By any means necessary. Even if that child does not come from Cygnus Black.
