«Infertile Husband, Happy Ex-Boyfriend» by Lovelace Anfisa

This is a cuckold erotic work, with explicit sex scenes.

When the news comes through that their failed attempts for a baby are down to her older husband, Samantha berates him for making them wait for the sake of his career. It turns into a huge argument that she ends by saying if he can’t get her pregnant, she’ll find someone who can. That someone is an ex-boyfriend she offers herself to for the night, and she forces her husband to watch as she cuckolds him with a virile, younger man.
