Celeste

I never wanted a new family.

Especially not one with glass walls, a private chef, and a stepbrother who looked like sin wrapped in designer clothes.

The Monroe mansion sat on top of the hills like a crown. Its white walls sparkled under the perfect blue sky. I stared at it from the back seat of the fancy car, holding my old, worn suitcase tight against my chest.

It was the only thing I had left from my old life. The only thing that still felt like mine.

Mom sat beside me, smiling so wide I thought her face might crack.

“Don’t look like you’re going to a funeral, Celeste,” she said, checking her makeup in a small mirror.

“Don’t act like we just won the lottery,” I shot back.

She gave me that same disappointed look she’d perfected my whole life, but said nothing. She was too happy, too caught up in her fairy tale ending.

And why wouldn’t she be?

She’d married Richard Monroe. The man who owned half of California. The man with billions in the bank and a face that still turned heads, even with gray hair. Her dream had come true. Poor girl marries rich man. Rags to riches. Cinderella story.

For me? It felt more like a nightmare dressed up in designer clothes.

The car came to a stop, and my stomach twisted into knots.

The front door opened before we even reached it. A woman in a perfect black and white uniform stood there, smiling like she’d been practicing in a mirror.

“Welcome home, Mrs. Monroe,” she said to my mother. Then she turned to me. “Miss Morgan. Mr. Richard is waiting inside for you.”

“Darling!” a deep, smooth voice called from inside.

Richard Monroe walked down the steps like a king coming to greet his subjects. He probably closed million-dollar deals with that same confident smile and a sharp knife hidden behind his back.

He kissed my mother, and she giggled like a teenager. The sound made me cringe, but I couldn’t look away as I stood there, clutching my suitcase tightly.

“Celeste,” Richard stated, turning to me. His smile was warm. “You look beautiful, sweetheart.”

“Thank you, sir,” I replied quietly, staring at the floor.

“Sir?” He laughed like I’d told a joke. “We’re family now. Call me Dad.”

My stomach twisted. The word Dad didn’t belong to him.

This man? He was just the guy who married my mother for reasons I didn’t want to think about.

“Call him Dad, Celeste,” Mom said sharply. “Don’t be rude.”

Rude. She thought I was being rude. This woman, who never cared about my feelings before, never asked if I wanted to move, if I wanted a new family, if I wanted any of this.

“Dad,” I finally said.

“Good girl,” Richard muttered, looking pleased with himself. “Jace will be home soon. But first, let’s get you settled. Maria, show them to their rooms.”

Jace.

My new stepbrother.

I hadn’t met him yet, only saw one picture on Mom’s phone when she was showing off her new life to her friends. He was tall, with broad shoulders, dark messy hair, and a tattoo peeking out from his collar.

He looked like the kind of boy mothers warned their daughters about.

And now he was my brother.

The word made my skin crawl.

The inside of the mansion was even more overwhelming.

Shiny marble floors that reflected everything like mirrors. Crystal chandeliers hanging from impossibly high ceilings. A staircase so wide and grand that an entire wedding party could walk down it side by side.

Everything screamed money, power, and status.

Nothing felt like home.

I followed Mom as the maid took us upstairs. “Your rooms are on the third floor,” Maria explained. “The family wing.”

Family wing. It felt like we were truly a family, like we belonged here.

She opened a set of double doors to reveal my new bedroom.

I stopped breathing.

It was huge. Bigger than our entire old apartment. Cream-colored walls with gold decorations. A bed so big I could probably fit five people on it. A chandelier hanging from the ceiling. Windows from floor to ceiling with a view of the whole city.

And a closet. A whole room just for clothes. It was bigger than my old bedroom.

I dropped my suitcase on the floor. The sound echoed in the space.

“So this is where you dump me,” I hissed.

“Celeste, please,” Mom sighed. “Can you just try? For me? Just this once?”

I stared at her, really taking in her appearance. She was dressed in a designer dress, adorned with expensive jewelry. Her hair was styled impeccably, and her makeup was flawless.

She looked like a stranger.

“This is the best life I could give us,” she responded softly, like she was trying to convince herself. “I did this for you, for us. Can’t you see that?”

I wanted to scream and tell her that I never asked for this. I was happy in our small apartment and didn’t need fancy rooms, designer clothes, or a stepfather with billions of dollars.

I just needed her to care about me. To ask what I wanted. To see me as more than just a burden she had to drag into her new, perfect life.

But I didn’t say any of that.

“Why do you even care what I think?” I asked instead, my voice shaking. “You never cared before. Not once. You never asked if I wanted to move. If I wanted a new family. If I wanted any of this.”

“Everything I’m doing is for you,” she said, and she actually looked hurt. Like she believed her own lies.

“Sure it is.” I laughed, even though nothing was funny. “Keep telling yourself that, Mom. Maybe one day you’ll believe it.”

Her expression turned stern. “This is your room. I need to go find Richard.” She uttered his name like it was something precious. “Unpack, make yourself at home, and try to be grateful.”

She walked out without another word. The door closed behind her with a soft click.

I was alone.

I fell back onto the huge bed and stared at the ceiling. The silence was thick and heavy, pressing down on me like a weight.

I was on the verge of tears, but my anger was too intense to let them fall.

I hadn’t even started unpacking when I heard heavy footsteps in the hallway.

Then my door opened.

No knock, no warning, just opened.

“Are you kidding me?” I snapped, sitting up fast. “Do rich people not know how to—”

The words died in my throat.

He filled the doorway like he owned it, and everything beyond it.

Six feet of solid muscle wrapped in a tight black shirt that showed every line of his body. Gray sweatpants hanging low on his hips. Messy dark hair that looked like he’d just woken up. Sharp cheekbones that could cut glass. Full lips that curved into a cruel smile.

And eyes. Dark, dangerous eyes that looked at me like I was something he wanted to destroy.

Jace Monroe.

My new stepbrother.

His eyes lingered on my body, moving slowly and hungrily, as if he was savoring every moment. It felt like he was committing every detail to memory.

A rush of heat flooded through me, causing my skin to tingle and my heart to race.

I hated it. Hated the way my body reacted to him. Hated that some part of me recognized something in him.

“You’re in my room," he announced, his voice deep and rough, like gravel and honey mixed together.

I blinked, trying to find my voice. “Excuse me?”

He stepped inside and shut the door behind him. The click of the lock sounded impossibly loud.

“This used to be my room,” he muttered, walking closer. Each step was slow and deliberate. Like a predator stalking prey. “Until your gold-digging mother moved in and took over my house.”

Fire shot up my spine. “Watch your mouth,” I snapped, standing up.

“Or what?" He stepped closer, so close that I could see the green flecks in his dark eyes. I could even smell his cologne, something clean, dark, and expensive that made my head spin. “You’ll run crying to your mommy?”

“I’ll kick your ass,” I said, lifting my chin.

He laughed; the sound was cruel, cold, and joyless. “You? You’re barely five feet tall. I could break you with one hand.”

“Size doesn’t matter when you know where to hit,” I shot back.

Something dangerous flashed in his eyes. Something that made my stomach flip.

“This is my house," he said softly. “My room, my life. You and your mother? You’re nothing but parasites who moved in and ruined everything.”

“Oh, I’m sorry,” I said, my voice dripping with fake sweetness. “Sorry for the inconvenience, Your Royal Highness. I didn’t realize you were such a spoiled prince who throws tantrums when things don’t go his way.”

His jaw tightened. “Don’t talk to me like we’re equals.”

“Don’t talk to me like I begged to be here!” I shouted, all my anger spilling out. “You think I wanted this? You think I wanted to move into some stranger’s mansion and pretend to be part of his perfect family? I didn’t ask for any of this!”

He stared at me. Then he moved closer. So close I had to tilt my head back to look at him.

“Here’s a rule for you, little stepsister," he murmured in a low, almost whisper-like voice. “Stay the hell away from me. Don’t talk to me. Don’t look at me. Pretend I don’t exist. If you get in my way or try to play happy family with me, I will make your life a living hell.”

I should have been scared, backed down, and apologized. But I didn’t.

“You came into my room,” I said, my voice steady even though my heart was pounding. “You approached me. So maybe you should follow your own advice.”

His eyes flashed. “I’ll walk into whatever room I damn well please. This is my house.”

“Then next time,” I snapped, meeting his stare head-on, “knock first. Or I’ll scream loud enough to wake the whole neighborhood.”

His lips curved into a cruel smile. “Scream all you want, bitch,” he said, leaning down until his lips were inches from my ear. “Nobody’s going to save you here. Nobody cares.”

“What’s that supposed to mean?”

He pulled back and looked at me again. This time with pure disgust.

“You’re not even pretty,” he said slowly. Each word was meant to hurt. “So flat. So boring. So plain. I don’t know what game you and your mother are playing, but it won’t work on me. I see right through you.”

The words stabbed into me like knives.

He looked at me like I was nothing. Like I was dirt on his expensive shoes. Like, I didn’t deserve to breathe the same air as him.

And for one horrible second, I almost believed him.

Before I could say anything—before I could think of a comeback or defend myself—he turned and walked out.

The door slammed so hard the windows shook. Picture frames on the walls rattled.

I stood there, frozen, my hands shaking, heart racing, and body feeling like it was on fire.

What the hell just happened?

My skin was still buzzing from how close he’d been. From the heat of his body. From the way he’d looked at me—like he couldn’t decide whether to kiss me or destroy me.

This wasn’t just tension between step-siblings.

This was war. And I wasn’t planning to lose.

Moonbunnie

He was off-limits. I should hate myself for the way my heart raced whenever he looked at me, but I couldn’t. I wanted him. I wanted him so badly that I’d do anything to keep that desire buried… until it became impossible. Welcome to my first forbidden stepsister-and-stepbrother romance. I hope you’ll join me on this journey—comment, like, and share what excites you. Your support means the world to me. Thank you!

    Aria“Damon, I can’t accept this.”“You will. Because you have no choice.” He looked at me like I was nothing. “You knew our plan from the beginning. You knew what we were trying to do—get rich, have a good life. Jace was perfect for it. His father was loaded, and we were going to take everything. But you—”He stopped, and the disgust on his face made me want to die. “You ruined everything. Damn you.”“I’m sorry. You’re my everything, Damon.” I swallowed what was left of my pride. Despite the pain screaming through my body, I got out of bed. I fell to my knees on the hard floor. I crawled to him like an animal. I grabbed his leg and held on. “Please don’t throw me away. You’re all I have.”“You’re wrong, Aria.” He looked down at me like I was an insect. “You still have your Kelvin.”“He meant nothing,” I sobbed. “He was just... just something to pass the time. If I’d known, I never would have done it. Please, Damon. Remember where we started. Remember when we had nothing but each othe

    AriaWhen I opened my eyes again, pain hit me immediately. My head was pounding. My whole body felt like it had been broken into pieces.My vision was blurred, and everything appeared hazy.“You’re awake,” someone uttered.I turned my head slowly toward the voice. It hurt to move. There was a woman I didn’t recognize standing next to me.“Who are you?” My voice came out rough, barely working.“Don’t stress yourself, Miss,” she said gently. “You’re too weak right now.”Too weak. Then I remembered. Damon. The whip. The blood.“Am I dead?” I asked. Part of me hoped I was. At least then the pain would stop.“Dead? No,” she answered. “You’re alive, Miss. You’re just very weak.”We were still talking when the door opened.Damon walked in.My whole body started shaking. I couldn’t control it. Terror flooded through me like ice water in my veins.“One thing I love about bitches like you,” he said casually, sitting down in the chair as if nothing had happened. Like he hadn’t almost killed me.

    Aria“Why did you do it?” Damon’s voice was quiet when he asked, but that scared me more than if he’d yelled.I’d just finished telling him everything—about Jace throwing me out, about the scene at his office.“I’m sorry,” I whispered, my voice shaking. “I tried so hard to make him forgive me. I begged him, Damon. I got on my knees and begged, but he wouldn’t listen.” Tears started falling down my face. “He called me a bitch.”Damon moved closer to me. My heart started beating faster.“He’s right,” Damon muttered.“What?” I stared at him, not believing what I was hearing. “What are you saying?”“He’s right.” He looked straight into my eyes, and I didn’t recognize the person looking back at me. “You’re a slut. A lowly bitch.”“Damon,” I breathed out his name, like saying it would make him stop. It hurt so much more hearing it from him than from Jace. Jace hated me now, but Damon—Damon was supposed to love me.“You’re a bitch,” he screamed suddenly, and his hand flew across my face. The

    Mina“Do you like what you see, Jace?” I whispered, climbing onto his desk. I spread my legs wide, showing him everything.His eyes turned black with desire. The control he’d been holding onto snapped.“You’re such a naughty girl,” he growled, grabbing my legs. Without warning, he thrust inside me hard.“Ahhh!” I screamed as pleasure exploded through my body. He didn’t go slow or gentle. He fucked me like he was angry, like he wanted to hurt me and pleasure me at the same time.“Just like that. More,” I begged, my body shaking with each thrust. The room filled with my gasps and moans, the sensations overwhelming yet intoxicating.The desk scraped against the floor. Papers fell. I didn’t care. Nothing mattered except this feeling, this moment.Suddenly, he grabbed my hands and pushed me down flat on the desk. He turned me around roughly and entered me from behind. His fingers dug into my hips so hard I knew they would leave bruises.The desk creaked beneath us. My moans got louder. His

    MinaI spent an hour that morning choosing my dress. Not just any dress—the red one that hugged every curve of my body. The one that made men stop and stare. I put on my best makeup, painted my lips the color of blood, and looked at myself in the mirror.Perfect.Jace wouldn’t be able to resist me. Not today. Not when I looked this good and hot.My heart was beating fast as I walked into the office building. I could feel eyes on me, and I loved it. Every single one of them was looking at me like I was a goddess.“Good morning, Mina,” my coworkers said when they saw me. Their eyes went wide.“Good morning,” I answered sweetly, walking past them with my head held high.“You look so beautiful,” Joy said, her mouth hanging open a little. “You look so hot. Do you have a date with someone?”A date? I almost laughed. No one else was good enough for me except Jace. Soon, everyone would call me Mrs. Monroe. Soon, I would have everything I deserved.“Yes,” I lied smoothly. “After work.”Everyon

    Mina I fixed my hair, straightened my clothes, and put on my brightest smile. No one could see. No one could know how Jace treated me. “You’re back,” Celeste said when she saw me. “Yes.” I picked up my bag, keeping my voice normal. “I’m going to the restroom.” I rushed to the bathroom. I looked in the mirror. There they were—dark bruises already forming on my neck, like ugly purple flowers. I reached for my bag to get my makeup when Joy and the others walked in. “Mina, what the hell happened to you?” Joy’s eyes went straight to my neck. I opened my mouth to say nothing, then stopped. An idea formed in my head. A perfect, beautiful idea. “It’s nothing.” I looked down, like I was ashamed. “It’s not Celeste’s fault. It’s mine.” “What?” Joy’s face turned red with anger. “Don’t tell me she did this to you!” “No, she didn’t.” I shook my head quickly. “Please, it wasn’t her.” “You’re too kind, Mina,” Angel said, her voice hard. “Too kind. We know she’s the one. She proba
