Chapter 8: A Change in Atmosphere

I was glowing the entire way home, my eyes shining through the darkness as we walked uphill towards our holiday home. I could feel Matti next to me, tense and warm, his body silhouetted by the moonlight passing through the trees in the humid night air. The smell of his musk was mixed with the remnants of our encounter, and each time the wind blew I could smell him on myself, it was more intoxicating than the cocktail back at the club.

We reached the main road, the house was in sight, our sanctuary until our next connection. My jaw was tight, the frustrating need simmering inside me again each time I heard him grunt with effort next to me as we climbed the hill. I knew that I’d have to be careful at home, Mom and Dad’s vigilant eyes on us, the guardians of decency. It was almost like a challenge, daring me to push the boundaries further out of their sight.

The weight of guilt hung over me, each stray glance from them sending my heart racing, as if they could somehow sense the depths of our secret. But as much as I hated doing this to them, there was no atonement for something I intended to do over and over again—dragging myself and my brother deeper into this illicit coupling.

We finally reached the dimly lit porch, the surrounding houses sleeping in eerie stillness, but a shiver crept up my spine eliciting a strained sigh at the thought of seclusion with him.

As my hand moved towards the door, I felt a jolt of electricity grounding me. Matti’s hand clamped down on mine. I looked over at his flushed face, his sharp jaw, the mess of brown hair haphazardly swept back, I blushed, an uncomfortable heat spreading through my cheeks at his stern look. He was a year younger yet so much bigger.

“We have to stop.” He whispered. His eyes staring so deep into mine, I felt his gaze tugging at the edges of my frayed soul.

“Why?” I shot back, my volume rising, hurt mingling with raw need. Why didn’t he want more?

“You’re a reckless brat,” He hissed, moving closer, pinning my back against the door, “we could have been caught so many times, but you don’t care.”

My hand reached out to caress his chin as he leaned in, “Don’t act like you didn’t love every second...” I could feel his body shiver at my touch, “Every second of getting to fuck your sweet sister.” A giggle escaped my lips, heat blooming in my cheeks at my own boldness.

His hand swatted mine away, and I gasped as he clamped my cheeks, forcing my lips to pucker until no sound escaped me. His grip was unyielding, yet I melted under his emerging dominance.

“You really are sick, you know that...” His green-eyed gaze darkened, almost animalistic—he fought the tempest within, but I could see it pushing at the edges of his control. Yet he didn’t let it consume him as easily as I did myself.

His grip remained constant as he leaned in to kiss my swollen lips, his taste making my breath hitch, “But, I hate the effect you have on me.” His voice softened, but not his grip. He turned me around, pressing my face into the wall, I instinctively arched my back, presenting to him like an animal in heat, my shorts barely covering my decency as my hips wiggled invitingly.

“This is what I mean,” he breathed into my ear, his cock pressing against the plush softness of my ass, his hands kneading the soft flesh, sending shudders through me. “You can’t even control yourself, can you?”

“Maybe you need to fuck it out of me, big brother?” My voice came out sultry, a brash challenge underpinning my words.

“Are you going to use that big cock to teach your sister a lesson?” I teased, my hips swaying in tight, suggestive circles, revelling in the trail of heat left behind.

“Are you going to fuck me into submission?” I teased, my hips grinding back into him harder.

“I should shut you up right now,” He hissed, turning me around, breaking the sweet contact I was savouring, “Wash that filthy mouth out.” This wasn’t the Matti who arrived here, this was a beast I created and I delighted in it.

I met his gaze with a challenging smirk; he knew I was playing into his desires. Yet, the need to dominate me crashed over his features, tension coiling in his jaw, a white-knuckled grip indicative of the struggle beneath his calm facade—my sweet brother, unravelling.

With a swift motion, he grabbed the neck of my shirt, tugging me downward, provoking a whimper as I fell to my knees before him, an act of both submission and plea, my hands coming together in prayer around his muscular forearm.

“I’m sorry for being such a brat,” I confessed, looking up at him through wide, pleading eyes, glistening in the warm orange porch light. “I’ll be good, I promise.”

“Show me then...” he demanded, shifting the power balance back into his hands as my fingers curled around his forearm, grounding me in this moment of devotion.

I could feel the cold tiles on my knees as I looked up at him, knowing exactly what he wanted, my breaths were quick, my mind racing with the possibilities and the knowledge that behind us was a door, and behind that door were mom and dad, blissfully unaware of the depravity taking place.
