No, they are not very common in mainstream literature. Literature usually focuses on more positive or moral relationship models. But in some niche or experimental literature, such stories might appear to explore complex human emotions and relationship taboos.

The husband, though initially hesitant, respected her decision as he trusted her. This shows how in some 'wife first cuckold stories', communication and trust play a huge role.
