The car ride home felt surreal. As the door closed, darkness enveloped us, the only light coming from the distant glow of the dashboard. The soft hum of the engine and the rhythmic bump of the road lulled my parents into a casual conversation in the front seats, but all I could focus on was Matti beside me. The leather of the seat was cool against my slick skin, sticking uncomfortably with each shift, but I barely noticed.
My mind raced, every thought colliding with the next. The weight of everything felt unbearable, yet strangely exhilarating. I rested my hand on the middle seat, close—too close—to his, and as the car swayed with each turn, I let my fingers inch slowly forward. My heart pounded in my chest, loud in my ears, as my fingertips brushed lightly against his skin.
My breath caught. It was the briefest contact, but it sent a jolt through me. I held my breath, waiting, hoping. Would he pull away? Would he meet me halfway? The tension in the car felt suffocating, the air thick with unspoken desires. The soft whir of the air conditioning and the distant sound of the ocean faded into the background as I focused on that sliver of space between us—on the electric charge in the air, waiting to snap.
Then finally, his pinkie finger twitched, it hooked onto mine and clung on as the car jolted on the country road. My eyes strained but I couldn't see Matti through the darkness, but his sun-beaten scent filled the small space between us, his breath ragged. My heart pounded so hard I could almost hear it, as if trying to drown out the voices in my head that screamed this was wrong— there was something thrilling about being hidden from view, the cover of darkness feeling like a twisted blessing
I hooked his finger back, feeling our grip tighten as we hung onto each other in desperation. My breath hitched and my heart pounded as I began to gently pull his hand across the distance between us —the forbidden touch or the feeling of control over him. My breath hitched, and I fought to stay quiet, praying my nervous breathing didn’t betray us. I pulled his hand towards my thigh, it radiated my heat onto his palm as it drew closer, I felt his desire to touch his sister in the darkness, it was deliciously lewd act.
As he made contact with my soft skin I gasped audibly, prompting mom to briefly look back and smile, unaware of the corruption taking place inches from her face.
Matti’s hand clasped my thigh, his fingers digging into my wanting flesh, feeling his sister’s body, savouring my heat. His fingers trembled against my skin, hesitant, almost unsure. I could feel his hand shaking, betraying his nervousness as I slowly parted my legs, little by little as my mouth hung agape, blowing hot needy breaths on the back of dad’s headrest.
I felt his hands wander and explore me, my back arched and my mind emptied, all the self-preservation leaving my body as if my soul was escaping, becoming replaced with a feral instinct and heat. Through my lustful delirium I felt my hips turn slightly offering him access. His hands reached the tender skin of my inner thigh and his pinkie gently grazed the bottom of bikini. My heart jumped and my stomach tensed up as I held back a moan. The sensation of his finger through the fabric, grazing against that special spot. I was lost, my mouth dry and hanging open.
He tried to pull back—maybe he was scared. But before he could, I grabbed his wrist in a flash of desperation. My hand smacked against his with a quiet clap, loud enough that I froze for a second, panic jolting through me. I glanced at the front seat. Mom turned slightly, but then settled back, oblivious. A shudder ran through me as I slowly, deliberately guided his hand back, returning it to the spot where I wanted him.
I felt the heat of his palm searing into the soft flesh of my inner thigh, his nervous sweat leaving a path as it moved closer and closer. I arched my back and held back revered moans as his hand finally touched it. The length of his pinkie finger pressed deliciously into the slit of my steadily dampening pussy. In a flash of desperation, I clamped my legs around his hand, holding him there, every movement he made sending sparks to the sensitive spot between my legs. His subtle struggle only heightened the sensation, the friction against my clit making it harder to stay silent.
I grabbed his wrist and guided his movements as he relaxed, his forearm muscles flexing as he obeyed my instructions with his deliberate strokes. I purred silently as I made his hand trace delicate lines up and down, side to side, through the soft fabric of my bikini. My own brother exploring me like this in the backseat of the car, while our parents sat inches away, completely unaware. The guilt and the unholy crossing of boundaries between their kids unfolding deliciously just out of their sight.
My had still griped his forearm but the movements were now his own. He weaved delicious circles on my swollen clit, making sure to savour the wetness as he run his finger between my labia, pushing the thin fabric against me. I was losing control.
My mind was going blank with the pleasure and the added stimulation of the slick fabric. I was becoming light-headed, delirious with need as I slumped down in the seat, opening my legs till they brushed against his knee. The sloppy and squelching sounds of my soaked pussy being abused were drowned out by the radio, just as I was drowning in the waves of impending pleasure spreading from the depths of my belly. I gritted my teeth and furrowed my brow as my thighs shook, a potent shudder of climax spreading through me as I let go.
I was cumming from my brother’s tender touch, I was disgusted with myself, but that feeling only fuelled the fire of feral lust I felt by breaking this taboo.
I had to clamp his hand with my thigh to signal my release and protect my senses from the maddening over stimulation. His strong hands relaxed and made me shudder as they pulled away, leaving a cold void where they once were.
The air in the car felt stifling, smelling of sex and heavy with the weight of what we had just done. His hand slipped away, but the memory of his touch lingered, making my skin burn with the thought of what I should do.
I could feel the warmth of his body radiating through the small gap between us as I scooted closer, our skin briefly sticking together when my shoulder grazed his. I heard his trembling exhale, the nervous tension rolling off of him in waves. His reaction sent a thrill down my spine—he was vulnerable, and I knew I had him.
“Mom?” I asked, my voice breaking through the silence. Beneath my confident tone, I was a mess inside, trying to hold everything together.
“Yes, sweetie?” My mom’s nurturing voice made my heart pound with the realisation of proximity to my lewd acts.
“Ummmm, How long till we get home? I’m really tired.” My deceitful question stoked the fire in my stomach as my heart pounded. I needed to know how long I had left in this cloak of darkness.
“Well, sweetie, it looks like about 10 minutes… give or take.” My mom answered calmy without turning around.
“Perfect.” I responded with my voice crackling mischievously as my hand wandered to Matti’s thigh. My head was spinning, I felt invincible, drunk with the lustful power I held over my own brother.
The line had been crossed and there was no going back, I wanted to embrace the consequences of my deliberate seduction. Other boys were fine, but I needed something more, it wasn’t just about sex but the primal taboo nature of this forbidden fruit. I wanted to corrupt Matti and myself, this desire burned a hole in my chest as I rubbed my thighs together. What is happening to me?
My breath hitched and my heart skipped a beat as Matti whispered a hushed plea into my ear, his breath hot against my neck; “Please…”
It was over, my hands moved on their own as my fingers grasped the sandy hem of his shorts, tugging them forward with an urgency that matched the pounding in my chest. I felt the slick tip of his cock graze my hand as it sprang free and flopped against his raggedly breathing abdomen.
My heart pounded as I ran my finger against the length of his shaft, my stomach dropping as it just kept going. It was thick and long, it’s heat burning against my finger as I felt his pulse through his erection. My own brother hiding this from me for all this time.
I could hear his stifled moans, and his hands straining against the leather seats, he was desperately clinging onto control. He was frantic at his sister’s touch and I needed to calm him. Make him relax into this special moment.
I grabbed the base of his throbbing erection and pressed my lips to the slick skin of his neck, humming softly. I felt the forbidden intimacy ripple through me as he relaxed and melted into me, his body conforming to my curves as he breathed steadily.
I stole a quick glance at the front seat—mom and dad still blissfully unaware of the sin happening right behind them. My hands stroked gently, up and down, my wrist moving seductively as I savoured his essence.
His foreskin slid back with a slick pop, and I relished the wet heat of his cock, making sure to memorise every vein and contour. The more I played with his cock the slicker it became, my hands wet with my brother’s pre-cum as I tried to keep the noise to a minimum.
My mind raced, lost in the primal throes of lust, hypnotised by the sweet smell of his cock as it grew hotter and harder in my hand. My brother—my own brother—was falling apart under my touch. It was so wrong, so unforgiveable and yet it was all I wanted against all instincts of self-preservation.
I quickened my strokes, feeling him twitch and pulse in my hand, the slickness of his arousal coating my fingers. His breath was hot against my hair, his body tensing, his balls tight against his shaft, ready to drain. I knew he was close and I had to move quickly.
My face ducked down as I pushed my long hair out of the way, my lips sealing against the wet tip of his cock, sucking gently as he released. His body sunk back into the seat as potent streams of warm cum painted the insides of my cheeks, my throat working to swallow all he’s giving me, leaving no evidence behind. I was in a trance, sucking the cum out of my brothers cock and licking the tip clean, tasting the salty-sweet essence of our love.
As I pulled back I felt his breath on my cheek under the cover of darkness, it was hot and moist, leaving a lingering wetness on my skin. Lost in the moment I planted my lips, slick with his taste, on his, sealing us together once more before pulling away, back to my side of the car.
My heart beat like a war drum, the air was humid and the smell of our union spread through the car like a thick mist of passion. I couldn’t wait to be alone with him again.
