All Chapters of We shouldn’t be doing this, Step-brother: Chapter 21 - Chapter 30

SiennaThe moment the doorknob turned and the sound of footsteps crept in, I stood up instantly from Jaxon’s lap, my heart racing like a drum.I bent over the coffee table, pretending to scrub a non-existent stain the guys had missed during cleanup. My hand shook as I rubbed at the spotless wood, praying my face didn’t give me away.Behind me, Jaxon shifted suddenly adjusting his shorts that couldn't hide his hard and obvious erection. He cursed under his breath, leaning forward to grab some empty cups from the table, angling his body to hide his erected dick.And then...Ava stepped into the living room again.Her hair was messy, her face pale, and she carried that same dazed look she’d worn all morning. “Uh… hey,” she said, rubbing at her temples. “I, um… I came with Caleb last night and totally forgot my wallet at home.”I forced a smile, my chest tightening. “so what do you want us to do now?.”She moved around the room looking lost until her gaze flicked toward Jaxon. “Oh, ..… Ja

SiennaI waited, staring up at him, heart pounding as though my life depended on his answer. Jaxon finally exhaled, his hand slipping from my hair.“I… I don’t know, Sienna,” he said. His voice was low, careful, but the words cut through me like glass.“You don’t know?” I whispered, forcing a weak laugh that didn’t sound like me. “That’s your answer?”He sat up, rubbing his face with his hands, clearly frustrated. “I’m just saying… it’s complicated. What we’re doing… what this is… I don’t know how it ends. Or if it even can.”The lump in my throat burned. My chest felt heavy. I pulled myself away from him, ignoring the way his eyes followed me. “Okay. Got it.”I stood, gathering my clothes. My legs felt weak as I slipped them on quickly, refusing to look back. He didn’t stop me. Didn’t grab my hand. Didn’t say anything.In the bathroom, I leaned against the sink, staring at my reflection. My cheeks were still flushed from everything we’d done, my hair a mess. And my stomach… sticky fr

SiennaTyler’s smile broke the moment the word boyfriend left my mouth. He blinked at me, once, twice, like he couldn’t believe I had just said it out loud. His jaw clenched and for a second, I thought he was about to argue.“You’re joking,” he said, voice tight.I shook my head. “No, I’m not. I meant what I said.”He opened his mouth again, but before things could get ugly, Jaxon stepped forward, his arm brushing against mine, solid like a wall. He didn’t say much, he just stood there, tall and unbothered, watching Tyler with that look that said don’t push me.Tyler’s eyes darted between us, his chest heaving. Then, with a sharp scoff, he turned on his heel and stormed off, the flowers and half the gifts still clutched in his hands.The second the door shut, I let out a long, shaky sigh. My heart was still beating fast.Jaxon turned to me slowly, his lips twitching. “So…” His voice dropped into that teasing tone that always got on my nerves. “You have a boyfriend now? Hm. Who is he?”

SiennaThe creak of the door made my heart stop.Dad stepped out of their room, rubbing his eyes. He was in a T-shirt and sweatpants, laptop tucked under one arm. “Couldn’t sleep,” he muttered to himself, heading downstairs. I crouched low against the hallway wall, barely breathing, watching his shadow stretch long under the dim light.My palms were slick. One wrong move and everything would crash.From behind Jaxon’s door, I imagined him standing there, tense, waiting. I could almost feel his eyes through the wood.Dad’s footsteps padded down to the kitchen. A soft clink followed; the sound of water pouring into a glass. The fridge door opened, then shut. The quiet hum of his laptop starting up reached me a moment later.I pressed my back against the wall, shutting my eyes. Maybe he’d stay downstairs. Maybe I was safe.But then the floor creaked again. Heavy steps climbing the stairs.Panic clawed up my throat.I scrambled silently toward my door, twisting the handle. I didn’t slip i

SiennaAs soon as we got home, we had lunch arguing over who should eat the last slice of pizza we had ordered. After lunch, the house became unusually quiet. No voices, no footsteps, no clinking dishes from the kitchen. Just the faint hum of the AC and the rapid clicking of Jaxon’s game controller upstairs.I sat curled on the couch, the TV flashing colors I wasn’t even watching. My fork from lunch still lay on the plate beside me, but I wasn’t hungry anymore. My mind had drifted somewhere else…somewhere I shouldn’t even go.It happened weeks after our parents had married. I remembered it so vividly, like my brain refused to let me forget.I had gone upstairs to ask Jaxon something…I don’t even remember what now. But when I pushed his door open, it wasn’t words that greeted me.It was him.Leaning back on his bed, phone in his hand, his breath heavy and uneven. His fist moving, slow then faster while holding his cock, his lips parted in a soft groan. I could hear muffled sounds of mo
