"You know this is wrong," I whispered. Lucas looked at me the way he always does right before he closes the distance between us. "Yeah," he said. "I know." He kissed me anyway. We are stepbrothers. Our parents sleep down the hall. Every single thing about this is a disaster waiting to happen. But Lucas Hart has been living in the room next to mine for four months, and somewhere between the late nights and the secrets and the way he looks at me like I am the only person in the room who is actually real to him, this started feeling like the only thing that was real. I was not supposed to fall for him. He was not supposed to want me back. We told ourselves we would stop. We lasted four days. Now the walls are closing in. People are starting to notice. Our parents are happy and we are about to destroy everything they built. But I have spent my whole life disappearing to make other people comfortable. Lucas is the first thing I have ever wanted to keep.

My Stepbrother, My Sin Chapter Fifteen: Messing Around
POV: EthanI stared at the message on my phone, my heart beating fast. “I just arrived. Where are you?” The words from Julian made my stomach twist. What the hell was he doing here? He was not supposed to show up at my new school. I had ignored his texts for days, hoping he would get the message and stay away. Now he was here, in the same building, waiting for me.I kept walking down the hallway without looking up, my mind racing. Why now? After everything with Lucas, the last thing I needed was Julian appearing and making things more complicated. My thumb hovered over the reply button, but I did not know what to say.I didn't see where I was going. My shoulder slammed hard into something solid, like a wall. My phone flew from my hand and hit the floor. I looked up quickly, ready to apologize, but my words died in my throat. It was not a wall. It was Lucas.He stood there, tall and broad, holding my phone in his hand. His eyes were dark as he looked at the screen. My heart jumped.“Ar

POV: Lucas“Who the fuck is Julian?” I asked again, my voice low and sharp. The movie credits were still rolling on the TV, but I no longer cared about the film. My hand stayed tight on Ethan’s knee as I stared at him, waiting. The name on his phone screen had lit something ugly inside me.Ethan quickly turned the phone face down and shifted away slightly. “It’s not something important,” he said, his voice quiet. “I have a reason for keeping it like that.”I leaned forward, heart pounding. “A reason? Since when do you keep secrets from me, Ethan? We live in the same room. We share everything now. Or at least I thought we did.”He looked uncomfortable, eyes fixed on the dark TV screen. “It’s from my old school. Just someone I used to know. Nothing serious.”His words didn't calm me. If anything, they made the discomfort grow. I couldn't help but wonder when this started. When had Ethan begun hiding parts of himself from me? The thought twisted in my gut. I had not seen him with any gir

POV: LucasEthan was on his knees.The sight of him like that, naked, flushed, eyes wide with shame and desperate need hit me harder than any game-winning shot ever could. My cock throbbed painfully against my loosened pants as I stared down at him. He looked so fucking conflicted, lips parted, chest rising fast, like part of him still wanted to run. But he didn’t. He stayed right there, trembling.“Crawl to me,” I repeated, voice low and rough. “Say my name.”His face burned red. I saw the fight in his eyes, the way his hands clenched on the floor. He hated this. Hated how much he wanted it. But slowly, painfully, he started moving forward on his hands and knees, whispering brokenly, “Lucas… Lucas, please…”Each crawl made my blood run hotter. When he finally reached me, I tangled my fingers in his messy hair and guided his mouth to my cock. The first wet heat of his lips wrapping around me pulled a deep groan from my throat. He was hesitant at first, but then he took me deeper, t
Last Updated : 2026-06-05My Stepbrother, My Sin Chapter Twelve: I Tried To Push Him Away
POV: EthanLucas held my wrists tight above my head, pinning me against the wall. My heart pounded so hard I could feel it in my throat. His body pressed into mine, hot and solid, and I could barely breathe. The towel had slipped off completely, leaving me naked while he was still fully dressed. His eyes locked on mine, dark and full of something I couldn’t name.I breathed hard, chest rising and falling fast. My mind spun. Why did this feel so familiar? The pressure of his hands, the way his hips pushed against me, the heat of his breath on my neck. It was exactly like the dream. But the longer I stared at him, the clearer it became. That wasn’t a dream. It had really happened. We had done this before. Lucas had been inside me, touching me, making me moan his name. And he had pretended like nothing changed between us.The realization hit me like a wave. My face burned. “It wasn’t… it wasn’t a dream,” I whispered.Lucas’s lips curved into a small, dangerous smile. He didn’t deny it.

POV: EthanI woke up with Lucas's arm draped over my waist. His breath brushed the back of my neck, warm and steady. The sheet tangled around our legs. Sunlight snuck through the blinds and painted stripes across the bed. For a second everything felt normal, like any other morning. Then the memorie

POV: LucasI could not get that night out of my head. The wrestling over the controller, the way Ethan had looked up at me on the floor, the way my body had reacted like it knew something my brain refused to admit. I told myself it was nothing. Just the newness of having someone else in my space al
