Engaged To My Stepsister, Obsessed With Me.Updated at Aug 13, 2025, 12:35
I agreed to sleep with a stranger to save my mother’s life. The next day, he walked in… as my stepsister’s fiancé. Now he lives in our house, whispers in my ear when no one’s looking, and reminds me of everything we did that night. I swore it wouldn’t happen again. Then the pregnancy test turned positive.One desperate night, Thalia made the biggest mistake of her life. Her stepsister, Chloe, had been secretly switching her mother’s medication, and offered her a twisted deal: spend one night with a stranger, and she’d switch one pill back to the real thing.It was supposed to be quick, anonymous, forgotten.But the next morning, Chloe introduced the richest billionaire, a tall, dangerous man to her. “This is my fiancé, Stefan,” she said.Thalia’s blood turned to ice. It was him.And Stefan? He remembered her, and he wanted more.He moves into their home under the guise of wanting to be close to Chloe, but his eyes are always on Thalia. He corners her in empty hallways, steals moments behind locked doors, and makes it clear he will have her again, no matter the cost.Thalia swears to stay away. She swears she won’t give in.Until one night, she breaks.And then it happens again. And again.She knows it’s wrong. She knows it’s dangerous. But with Stefan, every touch burns, every kiss feels like a sin she’s willing to commit.Until the two pink lines appear…Now, she carries the most dangerous secret of all, a child that could destroy everything. And Stefan? He’s not about to let her walk away.
