Sister In Law Erotica Novels & Stories

My mom, who works as a lawyer, decides to take me to court just because I refuse to donate my platelets to my younger sister, Lindsey Finch. I explained to her that I have a blood clotting disorder, and having an extremely low platelet count would put my life at risk. But she screamed at me through tears: “Can’t you just stop pretending? Do you really have to let your sister die? How could I have raised such an ungrateful wretch?” I lost the case, and my platelets were forcibly taken. I suffered a massive hemorrhage and died a miserable death alone in a deserted corner.

In my previous life, at the mate selection ceremony held by our pack, the Silvermoon pack, I saved a wolf that had suffered a crushing defeat in a territorial war. He turned out to be the Alpha heir of the Sunfire pack, Julian Sterling. To repay me for saving his life, after Julian returned to his pack, he immediately announced that I would be his future Luna. Within a year, I gave birth to a pure-blood Alpha, which was extremely rare in the Sunfire pack. Julian was overjoyed, and he named me his Luna after his father passed on the leadership to him. I not only had a mate who was outwardly loyal to me, but I also held an unparalleled position. As for my sister, Rosalie Ashford, she chose Jacob Blackwell, the courageous Alpha heir of the Stoneridge pack, to be her mate. However, she suffered because of her betrayal, and in the end, she was sent back to the Silvermoon pack. The pack believed that Rosalie had tarnished the glory of the pack, so they banished her. I took pity on her loneliness, so I brought her to the Sunfire pack's territory. However, she grew jealous of me. She killed me with silver-infused poison, and she even threw our pup off a tower, killing him. When I open my eyes again, I have returned to the day of the mate selection ceremony. I watch as Roselia runs without hesitation toward the dying wolf in the woods, Julian. Hence, I know that she is reborn as well. However, she has no idea that while it may be easy to save an Alpha, it's exceedingly difficult to bear his pure-blood descendant. Being the Luna of the Sunfire pack is anything but easy!

I have a duty to uphold my family's reputation, image, and power. It all became mine the moment I entered an arranged marriage with Tad Davenhall. But behind the perfect smiles and flashing cameras lies a life built on control and pressure. My marriage to Tad was never about love or loyalty. It lacked both. And more. The first time I saw Timothy Davenhall was at my family's Gala. The moment our eyes met, I felt our souls connect. He was mysterious, calm, dangerous, and everything Tad wasn’t. One look from him, and it felt like my skin was on fire. In that moment, I knew I had to stay as far away from him as possible. But fate doesn't care about boundaries. Now my marriage is crumbling, and while one man looks at me like I’m a burden he can’t wait to discard, the other looks at me like I’m the light to his dark world. Loving him means breaking every rule. But staying means losing myself completely. Still, either one of those choices destroys us both.

My mother has volunteered at our neighborhood church for over a decade. Christmas drives, Sunday service, any neighbor in trouble, she's the first one there. Everyone says God sent her to us. She thinks so too. She says God wants her to be generous, so she is. The thing is, when no one's watching, the generosity always comes out of my pocket. After she remarried, she doted on my half-sister Serena. Serena picked up a box of cold medicine for her, and Mom handed Serena the keys to my Tesla. Serena mentioned she needed to renew her car insurance, and Mom wired her the surgery fund I'd been saving for two years for my daughter Emma. That afternoon, Emma collapsed on the floor, lips turning blue, gasping for air. Her medicine was crushed into the carpet. Mom fished the last pill out of her pocket and dangled it in front of me. "Apologize to your sister, and I'll give Emma the pill." I got on my knees. But that same day, she gave away the cardiology appointment I'd spent three months getting. She gave it to Serena. What she didn't know was that the name on the appointment was her own.

Warm lips pressed against the sensitive skin of my neck, just below my ear, sending waves of shock down my spine. “After promising me a hot fuck, you decided to ditch me, huh Clara?” a low, male voice murmured into my hair as his hands slid down, palms flattening against my stomach, pulling me flush against a hard, solid body. I wanted to push him away, probably punch him in the face also but I'm Clara. He thinks I'm her and I have to be her. I took a deep breath, a wide smile on my face as I turned in his arms, finally looking at him. To my surprise, he was handsome, dark hair, strong jawline and I could see the confidence in his eyes. He knew Clara...maybe intimately. "I thought she has Jeremy, does she just fuck around now", I thought. “I got held up, I'm sorry,” I managed, forcing Clara’s sly smile onto my face, praying it looked convincing. “Uh-huh,” he said, his voice a low rumble. He didn’t believe me, but he didn’t care. His hand came up, his thumb brushing my lower lip. “You owe me, Clara. Big time.” ****************************************** Jenna has always had the perfect life, Her mate, Damon...the Alpha of the pack who accepted her, a pack that wanted her as their Luna.....
