How Does 'I Slept My Sister'S Fiance' End?

--- This book is a sequel to "Marrying a Disabled CEO in my Sister's Place", but both stories can be read separately --- "My ex-fiancé cheated on me with my friend. Having his hot billionaire brother as my revenge partner seemed like a perfect plan, but... Maybe it went too far when I ended up in his bed.” Millicent Bianchi has always been known for being a good girl and a kind person. Revenge has never been part of her vocabulary. However, when she discovers that her fiancé had an affair with her friend, Millie decides that's going to change. This man's schemes are threatening her family and, for that, she's going to make him suffer. And, for that, she needs the most unexpected partner possible: Isaac Carnby, her ex-fiancé's mysterious and rude half-brother. This meeting of two revenges should be nothing more than a deal. But... "Tell me, Millicent." he murmured in her ear, until she was no longer able to contain her moan "Tell me you've never felt with him the way you feel with me."

On the night of my sister’s engagement party, my life officially crashes. Again. All because of one name on the invitation. Zachary de Sanctis. My sister’s fiancé. Fiona. My ex, the guy I punched in the face five years ago. Heir to the richest old-money family in Europe. And one tiny detail only God and I know: he’s the father of my twins. For the past five years, I’ve been hiding out in a little town in Oregon, working as the CEO of a IT firm while chasing two four-year-olds who look more like their father than me. Isaac and Isabella: two mini De Sanctis clones with the last name Gómez, razor-sharp mouths, brains that run too fast, and a talent for causing trouble exactly when I need peace. My family knows I came home pregnant and alone. They just never asked who the father is, and I never offered an answer. As far as they’re concerned, I’m still Arabella Gómez, the wild one who lost her way. I thought going to Fiona’s engagement party would just mean a few hours of fake laughing, then a quiet drive back to my glass-walled house in Oregon and two sets of blue eyes calling me Mommy. Until Zach walks into my parents’ living room holding Fiona’s hand… and his gaze stays on my face a little too long. He can’t find out about Isaac and Isabella. Fiona can’t find out her perfect fiancé was mine first. And my family can’t know what really happened five years ago. Hiding a scandal between two rich dynasties is one thing. Hiding two chaotic twins who are basically their father’s face copy-pasted? That’s the real nightmare.

“Give me one reason, Liv.” He stalked toward me, cornering me against the edge of the desk. “One good reason why I shouldn’t bend you over this desk and f*ck you senseless.” My breath caught. “This is wrong, Damon. So wrong.” I pressed my palms flat against his chest, trying to create space. “You’re my brother-in-law…” “Not yet, love,” he whispered, fingers curling around my waist possessively. “You’re still engaged to him, but the man you’ll be getting married to…” Two fingers slipped into my heat, making me gasp. “…is me.” I should’ve walked away. I should’ve resisted. But I couldn't forget what it felt like to be his. * Olivia have the perfect life. The perfect fiancé. Marcus is everything she thought she wanted—sweet, charming, dependable.

One reckless night, I woke up in the bed of Ethan Van Horn — my sister’s ruthless billionaire fiancé. Now I’m pregnant with his child, and our powerful families have only one solution: force us to marry. He despises me for destroying his future. I hate him for treating me like the thief who stole what was never mine. Trapped in his luxurious penthouse, every cold glance turns into burning tension and every sharp word into forbidden desire. But the real danger isn’t the man I’m forced to call husband. It’s my sister — who will stop at nothing to take back the life and the man she believes are still hers.

On the night of my engagement party, I found my fiancé with his hands in my sister’s hair. I thought the betrayal ended there. I was wrong. Minutes later, Ethan stood in front of both our families and announced that he was in love with Ava. My sister. While everyone rushed to comfort them, I became the villain for refusing to smile through my own humiliation. Then Damien Black walked into the room. Powerful. Untouchable. The one man Ethan feared. Before the night ended, Damien handed me a contract. One year. One marriage. One chance to save my father’s company. All I had to do was become his wife. I should have said no. Instead, I signed. Now my ex can’t stop watching me. My sister can’t stop competing with me. And the man I married keeps protecting pieces of me I thought nobody noticed. The problem is that Damien Black is hiding something. And every day I spend with him makes me less certain that our marriage was ever supposed to be just a contract.
