All Chapters of We shouldn’t be doing this, Step-brother: Chapter 151 - Chapter 160

SiennaMy phone buzzed nonstop.Jaxon.Again.And again.I sat on my bed, knees pulled to my chest, trying not to cry again. I hated how much power he had over my mood. I hated that stupid picture. I hated that I kept seeing his smile in it like he belonged somewhere else. With someone else.But most of all… I hated that he had no idea why I was acting this way.Another message came in.Jaxon: Please, Sie. At least tell me you’re okay.I swallowed the lump in my throat and didn’t reply. I couldn’t. Not when my emotions were this raw.A moment later, my phone lit up again—but this time it was Kendra.Kendra: Babe Jaxon just called me 👀He said u haven’t been responding. U good?I wiped my eyes quickly.Me: I’m fine. Just tired.A lie.A big one.But I couldn’t let Kendra dig deeper or suspect anything. Not yet.Kendra: Okay oo. Just checking. He sounded stressed 😂Anyway, tell me if you wanna talk.I typed “sure” and locked my phone.Seconds later, it buzzed again.Jaxon—of course.M

SiennaI woke up with the kind of headache that feels like the night sat on your chest and refused to move. The sun was already leaking through my curtains, bright and loud, but everything inside me felt dim.My bedside table was empty.No phone.No iPad.No smartwatch.Nothing.Just silence.And the echo of my dad’s voice from last night—“Who are you on the phone with? Don’t lie to me. Was it Jaxon?”“You’re grounded. All of it—gone. Hand them over.”“You’re done talking to him.”I squeezed my eyes shut. The memory still burned.A soft knock came against my door. Not my dad’s heavy knock. This one was light, controlled. Lena.My Step-Mum, Jaxon’s mum“Sienna?” she called gently. “Your dad said I should check if you’re awake. Breakfast is ready.”“I’m awake,” I muttered.Another pause. “Are you okay?”No.Yes.I don’t know.But I said, “I’m fine,” because it was easier.She sighed. “Come down when you’re ready.”Her footsteps faded.I dragged myself out of bed and splashed water on

SiennaThe morning dragged like it had weights tied to its ankles.Every class felt twice as long.Every teacher sounded like slow-motion audio.Every friend who waved at me felt like a reminder that I was on lockdown.I kept checking the clock even though I didn’t have a phone to check.By the time the break bell rang, my chest felt tight from holding everything in.I walked out to the courtyard like a ghost—then I heard footsteps running behind me.“Sienna!”Kendra.Before I could turn around, she hooked her arm through mine and pulled me behind one of the pillars near the staircase.“Okay,” she said, eyes wide, breath fast, “what the hell is going on? Your dad acted like a bodyguard this morning.”I closed my eyes.She saw the exhaustion on my face instantly.“Oh my God… talk. Now.”I let out a shaky breath.And I told her everything.How Dad overheard my phone call.How he confiscated all my gadgets.How he grounded me like I was a criminal.How he told me I’d only use the cloned

SiennaI barely got home before the tension inside me snapped. My dad’s SUV still burned in my mind—the horn, the glare, the way he’d stared straight at me. Every time I thought about it, my chest tightened like a vice. I could feel my patience, my fear, my frustration—all tangled together—and I realized something had to give.“I’m done,” I muttered under my breath.My dad was in the living room, pacing like a predator, every step a reminder of control, of the leash he thought he had on me.“You think there won’t repercussion when you were fucking your step-brother?!” he barked. His face was red, veins popping at his temples.“I didn’t—” I started, but my voice cracked under the weight of everything he’d taken from me—my freedom, my privacy, my life.“I’m done listening!” I shouted back, louder than I meant to. “I’m so done with this! I’ll run away if I have to! I’ll drop out of finals if I have to! You can’t control me forever!”For a moment, the room went still. My stepmum, trying t

SiennaThe days blurred.Not soft, not easy—blurred like everything was happening too fast and too quietly at the same time.Tuesday.Kendra slipped me her phone during lunch.I walked to the far corner of the courtyard and called him.He answered before it even rang twice.“Sienna?”My chest warmed instantly.“I can do Friday,” I whispered, heart hammering. “I’ll come.”He exhaled, shaky, relieved.“Thank God… I’ve been losing my mind.”I smiled—small, hidden—before handing Kendra her phone back.The rest of the day felt… lighter.A little.Not enough.But enough to breathe.Wednesday.Kendra and I sat in the library, pretending to study.Her phone was under the table, screen up, brightness low.We texted him together.Kendra: We need to time it right.Jaxon: I’ll get the keys to the lake house by Thursday.Sienna: I’ll leave after 10pm. Dad will be asleep by then.Jaxon: I’ll wait for you. No matter how late.My pulse fluttered.Every message made Friday feel closer.Sharper.More
