ifex
I died on my wedding night, locked outside my own gates, watching my fiancé marry my stepsister while the world burned. Then I woke up. Three months earlier. Before the wedding. Before the outbreak that would tear my city apart. Before I ever trusted either of them. This time I remember everything — the date the collapse begins, the people who let me die, and the secrets my stepsister is willing to bury an audit to protect. I have three months to turn foreknowledge into power, expose the betrayal before it happens again, and survive what's coming. But I'm not the only one who saw this future coming. Damian Vale has been preparing for months, for reasons he won't explain, and every move he makes lands one step ahead of mine.

“Fuck, Claire… you’re still so tight for me,” Marcus groaned, driving his cock deep into her from behind. He reached around and rubbed her clit in rough circles while he fucked her, his other hand tangled in her hair. Claire came hard, crying out as her pussy clenched around him. That was only the beginning of three sisters, one man and secrets that will destroy everything. Evelyn thought she had the perfect marriage—until she discovered her husband Marcus had been sleeping with her middle sister Claire for years. The betrayal shattered her, their marriage collapsed and they divorced. Claire tried to walk away after everything and Marcus came begging, pulling her back into his bed with the same addictive sex that ruined her the first time. Meanwhile, youngest sister Lila carried the heaviest secret of all: she was a night club stripper with another name. She had a one night stand with her oldest sister’s husband and eventually got pregnant with his child after a series of raw, desperate encounters at the strip club where she danced. When Evelyn’s best friend Sophie found out Claire and Marcus had resumed their affair, she didn’t tell Evelyn. She blackmailed Marcus into her own bed instead. “You want my silence?” she told him as she sank down onto his cock. “Then you’ll fuck me whenever I want.” The lies and secrets held for a long time until Claire discovered Marcus had been sleeping with Sophie too. She told Evelyn everything. Sophie retaliated by revealing Claire’s resumed affair. Evelyn became furious and lashed out on them, then Sophie became defensive and expose Evelyn’s deepest secret; years earlier, Evelyn herself had an affair and abandoned the child that came from it. In the end, no one is innocent.

Betrayed by my Husband, So I Took His Sister - undefined novels & stories
Nyxenite
I had stopped pretending the night Sebastian sailed past our bedroom door for the third time and didn’t look back. I had married him to keep my father’s company intact. Out of my father's desperation. The vows were for the cameras and the board, everything else was ledger entries and quiet compromises. He chased his affairs in public while I held the facade. He saw my composure and called it martyrdom. He never figured out that my calm was armor, not devotion. Then Samantha came home, twenty-three, luminous, curious, the kind of warmth that made places in me I’d kept cordoned off ache. She drifted into my life with easy laughter and careless questions. A sister-in-law, that became my obsession. We started with late-night talks, her voice soft in an empty house, her hand brushing mine while we pretended we were discussing nothing at all. Those small touches stopped being accidental, but deliberate. While Sebastian was busy elsewhere, I took his sister. Not to win anything on a balance sheet, not to score a victory, but to finally have the means to protect who I am, and who I love. Samantha was bewildered at first, shame and curiosity tangling on her face, but the way she leaned into the moments we stole told me more than words ever could. It was messy and urgent and selfish. She became my refuge and my ruin. The tenderness I had once sold to survive became a liability I was suddenly proud to bear. When the scandal around Sebastian crescendoed, I didn’t hide behind the marriage or the name. I stepped into the light, shoulder to shoulder with her, exposed and fierce. I traded anonymity for that, truth wrapped in possession, and I, Mikayla Stonefield, would have done it again.
