Alpha's Rejected Omega Mate

Mallory's POV: It was Friday night. I was sleeping on the bed when a deep voice whispered in my left ear, “Mallory!” “Hmm,” I hummed and tried to push the figure away. But the person looming above me yanked a handful of my hair. “Ah!” I gasped. My eyes snapped open, and I saw who was above me. He was Ace Lennox, the Beta’s son. “Ace… What are you doing here?” I asked him as I gazed into his honey-brown eyes. “Shush…” He hushed me by placing his thumb on my thin lips. “I came to see how you’re doing. It’s your eighteenth birthday tomorrow. Don’t you think you deserve a birthday gift?” he asked as he stripped off his white top. “What kind of birthday gift is that? Why don’t you wait until tomorrow to present it to me?” I asked him. He shook his head and replied, “No, Mallory. You deserve to have the gift tonight. It’s very special, and I have been keeping it for you.” “What’s that?” I asked him, looking at his handsome brown face. Ace was the Beta’s son. Even though I am an Alpha’s daughter, I lost my respect because I haven’t shifted since I was born. My younger sister, Sonia, has been able to shift since she was fourteen years old. Everyone in our pack looked up to Sonia while they overlooked me. The worst part was that Sonia seemed to bask in it and made it look like I was the bad person. I love Ace and wanted to be his mate, but he does not speak to me during the daytime. He mostly avoids me, and I wondered how he was able to sneak into this room—and into my bed. My room was on the top floor of the magnificent two-story building that was the Alpha’s mansion. So it amazed me that Ace was able to get access in here. “I want to give you a priceless gift, Mallory. But you must promise me that you won’t shout and that you will enjoy it,” Ace said as he removed his trousers. I gulped hard, seeing his full broad chest—his strong, masculine abs—and I felt the urge to touch him. I knew that Ace was going to be my mate tomorrow, and I was wondering what the birthday celebration would be for me, since my father doesn’t like me. “I want to fụck you, Mallory. Just don’t shout, all right. I want you as much as you want me too,” Ace said, his brown eyes glowing in the night. “All right,” I agreed. At this point, it warmed my heart to see that Ace wanted me. I knew that everyone in the pack looks down on me, but seeing that I had someone who doesn't made me happy. “I know that we are going to be destined mates. I want you, Ace,” I told him, caressing his chest. He brought his face closer to mine. Ace kissed my lips hungrily. He was a twenty-one-year-old man, and many girls in our pack crushed on him. Even Sonia, my younger sister, hoped that by the time she turned eighteen she would become Ace’s mate. Sofia and I are only a year apart, because my father had married her mother after my mother died after my birth. We were half-sisters, and my father had to take up another Luna to help protect our pack. My mother was an Omega who happened to be my father’s true mate. When I was born, the pack doctor told my father that I was an Omega too—a weak link of the pack—which disappointed him. To make the whole matter worse, I was unable to shift like the rest of our pack members. I was short and not as tall as Sonia. She was tall, light-skinned, and very beautiful. I wasn’t a dwarf, but I was of average height and not as tall as her. It hurt me that no one wants me, but seeing that Ace wants me—and knowing that he was my fated mate—I agreed to make love with him, hoping that he would give me the best birthday gift. Besides, tomorrow was my eighteenth birthday party. “Are you ready?” Ace asked me. He was now fully naked on my bed. I swallowed hard, not believing that I was doing this with him. He had taken off my nightdress and left me completely naked on the bed with him. “Yes,” I moaned, breathless. Ace prepared himself to thrust into me. By the time he crossed the bridge and thrust into me, I moaned and cried, and he didn’t stop. Ace kept on with his actions until I was about to faint. “Damn it, Mallory! You’re so tight!” Ace kept going as he brought his face to mine. “You’re mine,” he said, burying his face in my neck. He brought out his fangs and bit me. “Ah!” I groaned as Ace climaxed in me. After a while, he pulled out of me and licked the spot where he had marked me on my neck. “I have to go now, Mallory. Happy birthday to you.” Ace kissed my lips and dressed up quickly, just as I heard the sound of footsteps approaching my room door. The door burst open, but Ace had already fled out the window. I wondered if he hadn’t broken his leg. My stepmother, Luna Lily, barged in. “Mallory, what are you doing on the bed, naked, at this time of the night? Were you the one moaning?” She marched up to the bed, met me, and yanked away the bedsheet I had used to cover my chest. “Mallory, you slut! Who were you fụcking in your room?” she growled and dragged me by my left arm, not minding that I was unclothed.
