My Stepbrother, My Sin のすべてのチャプター: チャプター 1 - チャプター 10

POV: EthanI stood in the driveway with a cardboard box pressed against my chest, staring at the big house that was supposed to be my new home. The sun beat down on my neck, and sweat already stuck my shirt to my back. Mom laughed at something her new husband said, her voice bright like I had not heard in years. She looked happy. Really happy. That should have made me glad, but it only twisted something tight in my gut.This whole thing had happened fast. One minute it was just the two of us in our old apartment, the next she was flashing a ring and talking about blended families. I had met Mark a few times before the wedding, but today was the first time I would actually live with him. And with his son.The front door swung open and Lucas stepped out. I knew who he was right away. Everyone at my old school knew Lucas from the rival basketball team across town. Tall, broad shoulders, easy confidence in the way he moved. He wore a plain gray t-shirt and shorts, hair still messy like he

Chapter 3 ControllerPOV: EthanI kept my eyes on the sketchbook even after Lucas asked the question. My pencil stopped moving. The words hung there between us. Does it bother you? Of course it bothered me. He stood there without his shirt, skin still damp from practice, and I could not pretend I had not noticed.I closed the sketchbook and set it on the desk. "I just think we should keep some space. Since we have to share everything now."Lucas pulled on a clean shirt, but the smirk stayed on his face. "Space. Right. In a room this size."He dropped onto his bed and picked up the game controller. "Come on. Parents are out again tonight. Let's play something before they come back with all their happy family talk."I hesitated. Part of me wanted to stay at the desk and hide behind my drawings. But another part, the one that kept replaying his question, wanted to see what would happen if I did not hide. I grabbed the second controller and sat on the edge of my bed.We started with a r

POV: EthanI stood at the front window and watched the car pull away. Mom waved one last time from the passenger seat. Mark honked twice like it was some big celebration. They were gone for the whole weekend. Anniversary trip. Just the two of us in the house.The door shut behind me and the silence hit different. No parents downstairs. No pretending at dinner. Lucas came up behind me and locked the door. His hand brushed my shoulder on the way past."Finally," he said.We ordered pizza and ate it on the couch in the living room. We did not talk much while we ate. Every few minutes our eyes would meet and we would both look away fast. The TV played some old movie neither of us cared about. When the pizza box was empty Lucas carried it to the kitchen and I followed him upstairs.In our room the air felt thicker than usual. I sat on my bed and pulled my hoodie off. Lucas stayed by the door for a second, then came over and sat on the edge of my mattress instead of his own. His knee presse

POV: Ethan"What the hell are you doing?"The voice cut through the haze like cold water. I jerked awake, gasping, hands flying away from my lap as if I’d been burned. The sheets were twisted around my legs. My heart slammed against my ribs so hard I felt dizzy.Lucas was sitting on his bed, cross-legged, watching me with that lazy, amused smirk I’d hated since elementary school.My brain short-circuited. In the dream he had been on top of me, inside me, whispering things that made my skin burn. Now he was five feet away, fully dressed, looking far too entertained.“You were moaning my name,” Lucas said, voice low and mocking. “Then you started touching yourself. Kinda hard to miss.”The room tilted. Heat exploded across my face, down my neck, all the way to my chest. I looked down — I was still in my pajama pants, but they were tented and damp at the front. No. No no no.I yanked the sheet over myself, mortified. “Shut up.”Lucas tilted his head, grin widening. “What? You embarrassed

POV: Lucas"What are you doing, bro?" Marcus asked, his voice laced with confusion.Yes. What am I actually doing? Because right now, I stood right between them, raising my hand like I was about to play referee in some stupid game. My shoulder was still pressed close to Ethan's, and I could feel the heat coming off him.I adjusted my shirt, trying to look casual, and asked, "Where are you two going?"Ethan let out a short laugh, shaking his head. "I don't remember when you became my father that I have to report my every move to you."The sound of his laugh caught me off guard. This idiot looked like more than the innocent face he always put on. There was a spark in his eyes, like he was enjoying pushing my buttons. It made something twist in my chest.My fist clenched hard at my side. For a second, I really wanted to punch that look off his face. Marcus must have noticed because he placed his hand on my shoulder.“Relax, man. Ethan is new, so I’m just going to show him around the sylla
