All Chapters of We shouldn’t be doing this, Step-brother: Chapter 31 - Chapter 40

Sienna The second I saw those headlights through Jaxon’s window, my whole body froze. My chest was still rising and falling like crazy, my skin sticky with sweat and from his cum still on my stomach.“Oh my God, oh my God, they’re here,” I whispered, already scrambling off his bed. My legs wobbled, almost giving out. I grabbed the tissues, wiped myself in a rush, and stumbled into my clothes with shaky hands.“Go….just go,” Jaxon hissed, pulling his shorts on. His hair was wild, his chest still slick with sweat, and even in the chaos he looked unfairly hot.I didn’t have time to think about that. I bolted out of his room barefoot, clutching my shirt halfway buttoned, and dashed across the hall to mine. My heart was hammering in my throat. I shut my door soft as I could and leaned against it, gulping air like I had just escaped being caught red-handed.Downstairs, I heard the front door unlock, then the familiar sound of heels against the tiles.“Hello?” Jaxon’s mom’s voice called int

JaxonThe sound dragged me out of sleep. Soft clinking, drawers sliding, a faint hum of movement downstairs. I blinked, disoriented, my phone screen glaring back at me: 4:49 a.m.For a second, I thought it was nothing — maybe the house settling. Then I heard it again. Pots. Cupboards. Someone moving around in the kitchen.My heart kicked.Mom.I turned my head, and there she was — Sienna. Curled up beside me, her sexy body warm against mine, tangled in the sheets. Her lips parted slightly, breathing slow, innocent in sleep.And we were in her bed. Together. Naked.“Damn,” I muttered under my breath, dragging a hand through my hair.I froze, listening harder. Mom’s footsteps. The fridge door opening. Water running. She was already up, probably prepping breakfast like she always did when she couldn’t sleep. If she came up now, if she even thought to check on us…I glanced at Sienna again. She shifted a little, her thigh brushing mine, her arm draped over my chest like she owned me. My t

SiennaThe morning air felt lighter than the kitchen had, but my chest was still tight with laughter I couldn’t let out. I was grinning without meaning to, and of course Dad noticed the second I reached him at the car.“Why are you smiling like that?” he asked, eyebrows lifted as he took the bag from me. “Something funny in there?”I swallowed the giggle threatening to burst out and shook my head. “Nope. Just… happy it’s revision week at school.”“Uh-huh.” He didn’t buy it, not fully. Dad had that way of studying me, like he could see straight through excuses. His lips twitched, but he didn’t press. Instead, he adjusted his tie in the car window and reached into his wallet.“Here,” he said, slipping a few bills into my hand. “That’s for you. And give some to Jaxon too, don’t keep it all to yourself.”I laughed, rolling my eyes. “I wouldn’t do that.”Dad gave me the classic dad look.“Okay, maybe I’d think about it,” I admitted, and he chuckled, patting my shoulder before climbing into

JaxonThe silence between us got louder. My pen slipped from my fingers, rolling off the desk, but neither of us moved to pick it up.Sienna’s eyes stayed on mine, wide and locked in place. Her lips parted like she wanted to say something, but nothing came out.My hand twitched, wanting to reach for hers.She shifted closer. Just a little. Just enough to send a charge crawling up my spine.“Jaxon…” she whispered.That was all it took—one word in that voice. I leaned in, my chest tightening, every nerve screaming at me to close the space between us.Her hand brushed mine. Her knee pressed against my leg. My breath caught.This was it. The barrier was gone.Then—HOOONK!We both jumped. The sound blasted through the open window, sharp and clear: a car horn in the driveway.“Crap,” Sienna gasped, jerking back.I dragged a hand over my face, half groaning, half laughing bitterly. “Of course. Perfect timing.”We scrambled to our feet, shoving books together, acting like nothing had been ha

JaxonAs soon as I go to my room, I sat there in the dark, the phone screen the only light in my room. My thumbs kept moving, even when my eyes burned."How to reduce cramps fast.""Does chocolate actually help period pain?""What not to say to a girl on her period."I read everything. Articles, blogs, random forums. Half of it sounded useless, half of it made sense, but all of it—every stupid word—I took in like it was gospel. Because it was her. And I couldn’t stand watching her curl up, biting back those sounds that weren’t pleasure this time but pain.I wanted to fix it.And that scared me more than anything else.Because wanting to fix her pain wasn’t stepbrother instinct. It wasn’t something safe. It was something deeper, heavier. Something I couldn’t name without admitting what we’d already done, what we’d already crossed.I let the phone slide onto the mattress, staring at the ceiling. My body was still restless, still carrying the phantom heat of her skin against mine, but my
