All Chapters of We shouldn’t be doing this, Step-brother: Chapter 11 - Chapter 20

SiennaKendra had barely stopped fanning herself from cheering on the sidelines when she leaned closer to me. Her eyes followed Jaxon as he jogged off the field, Ava’s voice ringing loud in the air as she called his name and clapped like she owned the spotlight.Kendra sighed sharply. “Are they back together?”I blinked, caught off guard. “What?”She tilted her chin toward Ava, who was practically bouncing in place, smiling at Jaxon like he hung the moon. “Jaxon and Ava. Don’t play dumb, Sienna. You saw her out there screaming his name. She looked like his personal cheerleader.”I forced a shrug, trying not to let my nerves show. “She cheers for anyone who gives her attention. Don’t overthink it.”Kendra folded her arms, lips tightening. “Don’t tell me not to overthink. I like him, you know. And if Ava thinks she can just slide back into his life, she’s wrong.”Her words stung in ways I couldn’t admit. My chest tightened, but I brushed her off with a half-smile. “Relax, Kendra. You’re

Dad’s voice carried up the stairs, firm and sharp.“Sienna! Jaxon! Downstairs. Now.”Then he headed down the stairs back to the living room.We both froze. My stomach tightened. The way he called our names wasn’t just casual. I glanced at my mirror, brushed down my hair quickly, and hurried out of my room. Jaxon was already at the top of the stairs, his jaw stiff. We exchanged a look, that silent what did we do this time? kind of look, before making our way down.When we reached the living room, Mom was already sitting there, her hands neatly folded on her lap. Dad stood beside her, looking way too serious for a weekday evening.“You two sit,” Dad instructed.I sank into the edge of the couch, my heart pounding like I was about to get grounded. Jaxon leaned back beside me, playing it cool, but I could tell even he was a little tense.Then Dad cleared his throat. “Your mom and I will be out of town this weekend. An urgent trip we can’t skip.”My eyes darted to Mom. She nodded, calm bu

SiennaThe front door clicked shut behind us, and for the first time all day, silence filled the house. No parents rushing around, no noise from the street, no distractions. Just me and Jaxon standing in the entryway, still flushed from the excitement of the football match.He tossed his bag onto the floor carelessly and looked at me with that sexy boyish grin, the one that always sent my stomach flipping. His hair was messy from the game, his shirt half untucked, sweat still clinging to his neck. I didn’t even have time to say anything before he stepped closer, closing the distance between us like he had been waiting for this moment all along.“You know,” he whispered, brushing a strand of hair behind my ear, “all through the game, I couldn’t stop thinking about this. About us… finally being alone.”My heart thudded hard against my ribs. The cheers, Ava’s voice echoing in the stands, even Kendra’s forced smiles...all of it melted away now. It was just us. His eyes darkened as he pull

SiennaWhen Jaxon finally dropped his phone onto the nightstand, I couldn’t stop laughing. The kind of laugh that bubbled out of me until my stomach hurt.“You’re insane,” I whispered, smacking his chest again as I curled into him. “Do you know how close that was? My dad literally asked for me.”He grinned lazily, that half-smirk that always undid me. “Relax. I had it under control. You think I’d let them catch you in my room half-naked? Not a chance.”I shook my head, still giggling, but my chest warmed at the way he said it. He sounded so sure, so protective, like I could actually trust him with every secret.We ended up talking for hours after that. About school. About the match. About stupid memories from when we were younger. And somewhere between the laughs and the little touches, sleep finally pulled me under while I was nestled in his arms.When I woke again, it was still dark, the soft glow of dawn slipping through the blinds. Jaxon was still asleep, looking so handsome and s

SiennaThe music was loud enough to rattle the picture frames on the wall. Someone had dragged in extra chairs, the coffee table was crowded with cups, and the whole living room smelled of chips, soda, and cheap cologne.I sat on the edge of the couch, nursing a drink I didn’t even want, my eyes betraying me every time they flicked toward Jaxon. He sat across the room, Ava practically draped over him like she owned him. Her laugh was too high, too eager, every word she spoke aimed at keeping his attention on her.Kendra sat beside me, sipping slowly, her jealousy written all over her face. Her eyes kept darting between Jaxon and Ava, narrowing whenever Ava leaned in too close. I knew that look. She wasn’t jealous of Ava because of me. She was jealous because she wanted Jaxon for herself.And then there was Tyler. Too close. Too persistent. He leaned in with his dumb jokes, brushing his shoulder against mine, his breath tickling my ear when he whispered.“You’re smiling again,” he said
