Sienna“Jaxon, stop..” My voice cracked, half-whisper, half-plea.My back slammed against the cold garage wall, his chest crushing into me, his scent drowning out the grease and motor oil.“We shouldn’t be doing this,” I breathed, fists pressing to his chest, trembling.“Why not?” His voice was low, rough, vibrating through me. His hands cupped my face, thumbs brushing my cheeks like he owned them.“You know why.” I swallowed hard. “The house. The rules. Them.”“Fuck the rules.” His smirk was dark, dangerous.“It’s not just rules. This… us…” My nails curled into his shirt. “It’s wrong.”“Is it?” His forehead touched mine, breath hot on my lips. “Because it feels like I’ve been waiting my whole life to be this close to you, Sienna.”My chest squeezed. “You’re an idiot.” I blushed“Maybe.” His mouth twisted into a daring smile. “But so are you for pretending you don’t feel this.”I opened my mouth, but his lips crashed into mine before I could answer.It wasn’t soft. It wasn’t patient.

SiennaThe room still smelled of him when I slipped out of his bed. My legs trembled as I pulled on my clothes, skin still humming from where his hands had been. The sheets clung to my thighs like they wanted to hold me there, but I forced myself to move.I paused at the door, my chest rising and falling too fast. What had we just done? My lips still tingled, swollen from his kisses, and every step I took down the hall carried the weight of a secret I had no idea how to bury.The house was quiet. The kind of silence that makes every creak in the floorboards sound like thunder. I pressed a hand to my chest, trying to calm the wild beat of my heart. No one could know. Not now. Not ever.I slipped into my own room before dawn had even softened the sky. My fingers brushed my lips again, and I shut my eyes, replaying everything. The way he pulled me close. The way I couldn’t say no. The way I didn’t want to.When morning came, I forced myself to act normal. To wash my face, fix my hair, an

SiennaThe kiss changed everything.We went back to pretending. We had to. Slamming doors, throwing insults, fighting over who got shotgun in the car. But it was just camouflage. Underneath it, the truth hummed like static.Every time he walked past me, I felt it.Every brush of his hand was a spark I tried to smother.Every look across the dinner table was too long, too sharp.I filled pages in my journal, my handwriting jagged, desperate.I hate him.I hate his mouth.I hate how much I want his mouth.I hate that I can’t stop.At night, the house turned into our playground. Parents asleep. Doors closed. The kitchen light flicking on like a secret signal.One night, he leaned against the counter, watching me smoke by the open window.“You’re still smoking,” he said.“So what?” I exhaled a thin stream into the dark.“Nothing.” His eyes didn’t leave mine. “You just… you look sad.”I scoffed. “I’m not sad.”“Yes, you are.” His voice dropped. He stepped closer, slow. “I see it.”I hated

SiennaThe world stopped spinning.My dad stood in the doorway, holding a basket of folded laundry, his face calm but unreadable. He looked at me first, then at Jaxon, then back at me again. My heart slammed against my ribs so hard it hurt.“What’s going on?” he asked, voice steady, eyes narrowing just slightly. “Why are you two in here with the door closed?”The laundry room shrank around us. The air grew heavy, thick. My throat burned with the scream I couldn’t release. It felt like a bomb was ticking inside the room, each second pulling us closer to disaster.Before I could even breathe, Jaxon moved.He was calm, collected, a master of lies wrapped in skin. He took a deliberate step away from me, breaking the closeness we’d just drowned in. He smiled smoothly and easy like it had been practiced, but it didn’t reach his eyes.“Hey, Victor,” he said evenly, gesturing at the dryer. “Sienna and I were just trying to get some clothes out of the dryer. Door was a little stuck.”I blinked

SiennaIt was too late for anyone sane to still be awake. The house had gone quiet hours ago, wrapped in that strange kind of silence where every tiny sound seems like a scream. The old clock in the hallway ticked like a hammer, each second louder than the last, beating against my nerves.Ava had only been here three days, but it felt like three months. Three endless days of her laughter echoing through the walls, of her perfume clinging to every corner, of her sitting just a little too close to Jaxon, smiling at him like she still owned him.And me? I wasn’t even a person anymore. I was a shadow in my own home, invisible, suffocating, unraveling piece by piece.By the third night, something inside me broke.I was in the kitchen making a sandwich I didn’t even want, dragging the knife through the bread with too much force, when Jaxon walked in. His hair was messy, his eyes ringed with exhaustion, his shoulders weighed down like he carried the whole world.For once, he didn’t look like
