Chapter 1: Twin Sin

Damien’s POV

The party was dying down, but the cool night air still carried the faint thump of bass from inside the frat house. Fairy lights strung across the backyard cast a soft glow over everything. I spotted Lila right away—my twin sister, standing close to Ethan as he leaned in and kissed her cheek, his hand resting on her waist.

My blood heated instantly.

“Ethan,” I growled, striding toward them.

Lila’s eyes widened. “Damien, don’t—”

I didn’t wait. My fist connected hard with his jaw. The sharp crack echoed as he stumbled. I grabbed his shirt and shoved him backward onto the grass. Straddling him, I drove my fists into his face again and again, feeling the warm slickness of blood on my knuckles.

“Who the fuck do you think you are, cheating on my sister?” I snarled between punches.

“Damien, stop!” Lila cried, her hands pulling desperately at my shoulders. Her touch was warm, her breath coming fast against my neck. Only then did I let her drag me off him.

She glared at me, cheeks flushed, chest rising and falling quickly. Without a word, she helped Ethan up and led him toward the campus clinic, her arm around his waist.

A few minutes later, I heard her footsteps hurrying after me as I headed toward the parking lot.

“Damien, you shouldn’t have done that!” she shouted, catching up. Her voice was sharp with anger.

I turned to face her. “Stop defending him, Lila.”

“Why shouldn’t I?” she shot back, stepping closer. Her eyes flashed as she glared up at me. “I can barely recognize his face now because of you. Who gave you the right to beat him like that?”

“I saw him at the club last weekend,” I said tightly. “Kissing another girl. I was trying to protect you.”

“Protect me?” She let out a bitter laugh, her breath warm against my skin. “You destroyed his face, Damien. That’s not protection. I never asked you to fight my battles.”

She jabbed a finger into my chest. “Stay out of my relationship. I trust him… and I love him.”

Those words hit like a punch to the gut. The thought of her loving anyone else twisted something dark inside me. She should be mine. Only mine. I hated the image of her in his arms, hated knowing she wanted him.

“You really think that girl was just his cousin?” I muttered, rubbing my forehead. “Open your eyes, Lila. He’s playing you.”

“I don’t care what you think,” she snapped, her voice trembling. “Stop poking your nose into my business. Just stop.”

She turned and walked away angrily, her hips swaying in that short dress. The faint scent of her vanilla perfume lingered in the air.

I slammed my bruised fist into the nearest tree, the rough bark biting into my skin. Pain shot up my arm, but it did nothing to ease the frustration burning through me—or the heavy ache I felt thinking about her.

This wasn’t the first time I’d lost control over one of her boyfriends.

And I knew it wouldn’t be the last.

Lila’s POV

I slipped quietly into Ethan’s dorm room later that night. The space was dimly lit, and the air still carried the faint smell of antiseptic from the clinic. Ethan lay on his bed, his face bruised and swollen, a cut on his lip still visible.

“I’m so sorry about what Damien did,” I said softly, sitting on the edge of the bed. “He didn’t know Katrina was your cousin. He even asked me to apologize for him.”

Ethan gave a bitter chuckle. “We both know your brother doesn’t apologize.”

He looked at me for a long moment, his eyes narrowing. “People on campus have been talking about you two.”

My stomach tightened. “What are they saying?”

“They say he’s in love with you. Obsessed.” His voice turned cold. “And I’m starting to believe it.”

“That’s ridiculous,” I whispered, shocked. “He’s my twin brother.”

“Is it?” Ethan challenged, holding my gaze. “Because the way you look at him… and the reason you’ve never let me sleep with you… I think it’s because you’re saving yourself for him.”

Heat rushed to my face. “How can you accuse me of that?”

But deep down, I knew he was right.

I had always felt something more for Damien—something dark and forbidden. It wasn’t normal sibling love. Late at night, when I was alone, I’d touch myself while imagining his strong hands on me, his hard cock sliding deep inside me, his voice growling my name as he took me completely.

Even sitting here now, the thought made warmth pool between my thighs and my nipples tighten against my dress.

Every time Ethan tried to get close, all I could picture was Damien instead.

This secret desire scared me, but the ache only seemed to grow stronger… and I wasn’t sure I wanted it to stop.

Ethan let out another dry chuckle, folding his arms below his chest. “I knew it. I wasn’t wrong after all. Look at you—you can’t even deny it. Geez, Lila.”

“I didn’t deny it because the accusation is baseless and senseless,” I said firmly. “Why would I ever be in love with my own twin brother? The guy I shared my mother’s womb with. I can’t believe you’d even think I’m capable of something like that.”

“Okay then, prove it,” Ethan said with a smirk, pushing himself up from the bed.

I stared at him suspiciously. “Prove what? And how?”

“Prove to me that you’re not in love with your twin brother. Prove to me that you’re not lusting after him.” He stepped closer, his fingers lightly tracing my exposed shoulders. “Shh, don’t talk. I’m not done yet,” he whispered huskily, pressing a finger to my lips.

“You must be wondering how I want you to prove it,” he continued, his voice low. “It’s simple. Let me take your virginity tonight. Let me pop your cherry.”

My eyes widened in shock, even though a part of me had suspected this was coming.

“You’re not going to do it, right?” he asked, smirking.

“I will do it, Ethan,” I replied, determination hardening my voice. “If that’s the only way to prove I’m not lusting after my twin brother, then fine. I’ll do it.”

“Okay…” he drawled. His finger ran slowly down the length of my curvy back as his lips traced soft kisses along the curve of my neck. I felt uncomfortable—deeply uncomfortable. Why did being intimate with my own boyfriend feel so wrong?

Ethan reached for the zipper of my dress and began pulling it down. I took a sharp breath and caught his hand, stopping him.

“I knew it,” he exclaimed, pulling away with clear disgust on his bruised face. “I knew you were lusting after your brother.”

“Say whatever you want,” I glared at him, my voice tight with anger. “But I’m not in love with my twin brother. I’m just not ready for sex.”

I huffed, turned sharply, and marched out of his room, slamming the door behind me. My heart pounded as I walked down the hallway, the mix of frustration, guilt, and that persistent forbidden heat still simmering inside me.
