All Chapters of We shouldn’t be doing this, Step-brother: Chapter 171 - Chapter 180

SiennaHis first thrust was slow, a deliberate, stretching invasion that stole the air from my lungs. A low moan was torn from me, muffled by the bedding. He held himself there, deep, letting me feel every inch of him. “You’re so tight,” he groaned, his voice strained. “So fucking perfect for me.”Then he began to move. A slow, torturous rhythm that built with every snap of his hips. His hand left my back and snaked around my hip, his fingers finding my clit with unerring accuracy. The dual sensation was overwhelming—the deep, filling thrusts and the sharp, precise circles he was drawing on my most sensitive spot. Pleasure coiled tight in my belly, a spring waiting to release.“Jaxon…” I cried out, my fists clutching the duvet.“Let go, Sienna,” he commanded, his pace quickening, becoming harder, more frantic. “I want to feel you come around me.”The command, the feel of him, the sheer animal need—it was too much. The coil snapped. My orgasm ripped through me, a blinding, white-hot wa

SiennaThe moment Kendra drove out of the hotel parking lot, she exploded.“SIENNA. MA’AM. I could NOT sleep because of you two!”I froze in my seat. “Oh my God, please don’t start.”Kendra slapped my thigh. “START? BABE, you were LOUD. I knew you and Jaxon had been doing things before, but girl… last night? Last night you were auditioning for a movie!”I covered my entire face.“Kendra, please— I’m begging you—”“No, because I actually sat up in bed at one point,” she kept going, laughing so hard her braids bounced. “You were moaning like someone’s daughter that has seen Jesus!”“KENDRA!” I screamed, but I was laughing too, even though embarrassment was eating me alive.“And Jaxon?” she said, leaning forward on the steering wheel. “That boy was calling your name like his soul was leaving his body.”My whole face burned. I pushed my head against the window.“I hate you.”She snorted. “You love me. And you love that boy. And your legs are probably still shaking.”I couldn’t even argue

SiennaThe banging started again. Harder this time.“SIENNA! OPEN THIS DOOR!” My dad’s voice was full of rage, trembling with anger.I pressed my back against the door, my chest tightening. My fingers clawed at the edge, but I couldn’t move. I couldn’t open it. Not yet. Not now.“Dad… please… I…” My voice cracked, and tears blurred my vision.“LOCKED AGAIN?!” he shouted, hammering his fists. “Do you think I won’t break it down?”I sank to the floor, hugging my knees, shaking uncontrollably. The step-mom’s quiet sobs drifted under the door. “Sienna… baby… please…”I wanted to disappear. To melt into the floor.My phone buzzed. Jaxon.I answered immediately, voice catching in my throat.“…Jax…”He was quiet for a moment, listening. Then his voice came soft, steady. “Sienna… what’s happening? Are you okay?”I couldn’t speak. The sound of my dad’s pounding and yelling filled my ears. Jaxon heard everything—my dad, my step-mom, the panic in my own breathing.“Pick up, Sienna. Talk to me.”

SiennaI didn't step out from my mum's house.I didn’t step foot in school for a whole week.A whole week of silence.A whole week of pretending I wasn’t breaking inside.A whole week of ignoring Jaxon’s calls, messages, voice notes—everything.A whole week of barely replying Kendra because even she didn’t know how to comfort me anymore.My birth mum let me stay in her house. She barely let me out of her sight.Every morning she checked my phone before giving it to me.Every afternoon she made sure I ate something even when my stomach felt like it was tied in knots.Every night she slept in my room because she was scared I’d cry myself into something worse.I was breathing… but not living.And Jaxon felt a thousand miles away.Not because he wanted distance—no.Because I forced it.And every day I fought the urge to text him, to call him, to just hear his voice and let myself collapse into the only person who ever made me feel safe.But I couldn’t.After what happened… I couldn’t.---

SiennaI woke up the next morning with my phone buzzing nonstop.At first, I thought it was the alarm.But no—It was the notifications.Hundreds.Maybe thousands.I blinked, confused for a moment…Then everything from last night hit me again:Jaxon’s video.The original one.The raw one.The one he’d posted himself before Instagram took it down for “community violation.”“I love my step-sister.”Those words were still fresh in my head.I had seen it the moment he posted it, I had watched it, I had replayed it.Then I panicked and ghosted him again.Now, this morning, everyone else had grabbed it, twisted it, edited it, reposted it and spread it like wildfire.I opened the first notification, and it was a screen recording of Jaxon’s video.Then another.Then another.Some cut the beginning.Some cut the end.Some slowed his voice.Some zoomed into his face like it was a confession video.Some removed the “step” and left only:“I love my sister.”I scrolled through TikTok, and the comm
