The final box was wedged into the trailer, the car groaning under its own packed weight. The long journey loomed, but first, a pressing need. I dashed inside, urgency gripping me, and slipped into the bathroom.
The door clicked shut behind me. With a sigh of relief, I hitched up the hem of my mini skirt, the fabric clinging briefly to my thighs before riding high. My fingers found the lace of my knickers, pulling them down just enough before I settled onto the cool porcelain, the first stream of relief a gentle hush. I sat there peeing thinking about Dan my boyfriend and hoping to see him soon as he was on holiday and I haven’t had sex in over a week. So yeah my pussy was hungry for dick.
“Amy! We need to go, now!” Mum’s voice, sharp with impatience, cut through the momentary peace.
I hurried, a quick wipe, the soft tissue a fleeting touch. My underwear was pulled back up, the elastic biting gently at my skin as the short skirt settled back around my hips. A flush, a quick splash of water on my hands, grabbed my handbag and I was out.
Downstairs, Mum was already installed in the passenger seat, Dad in the driver’s. I yanked open the back door, ready to collapse into my usual spot. But the space was gone. My brother, Adam, was practically cemented against the opposite door, a wall of luggage and boxes between us.
“Where the hell am I supposed to sit?” My voice was pure exasperation.
Adam, slouched in his worn t-shirt and grey jogging bottoms, offered a shrug that barely moved his shoulders. The fabric stretched taut over his biceps, a subtle ripple of muscle. “I don’t know, sis. Maybe you can sit on my lap?”
I rolled my eyes, the familiar sibling banter a weak defence against the mounting frustration. The suggestion, however flippant, drew a warmth to my cheeks. I was acutely aware of my outfit: the short skirt barely covering my upper thighs, my legs stretching out long beneath it, and the blouse, left slightly unbuttoned at the top, hinting at the curve of my chest beneath the soft fabric.
“No way,” I stated flatly, the thought of sitting that close, for that long, an instant rejection. My gaze swept over the chaotic backseat, searching for any empty square inch. “Can’t we just rearrange some of this stuff?”
“No,” Dad’s voice was flat, already starting the engine. The car hummed to life, a low rumble beneath us. “We’re not rearranging anything. We’re already ten minutes behind schedule, Amy. Just get in.”
I sighed as I got in the car hovering over Adams lap. I sat down on him as I relaxed with my bum pressed down on his crotch area as I shut the door. Facing forward with my back to Adam.
“Oh, super,” I said, a little too brightly, my voice tight. “Just what I always wanted for a road trip.”
The car rumbled to life, a low hum beneath us. This was going to be a long trip.
“Move your elbow!” I grumbled, already feeling squished. Adam barely shifted, his arm a solid lump against my side.
“You’re the one on my lap,” he shot back, not even looking at me.
“I know that!” I snapped, trying to wiggle a little. But there was nowhere to go. My knees were practically touching the seat in front, I felt awkward on his knees in my mini skirt.
Adam just chuckled, a low rumble beneath me. “Just relax, sis. It’s a long drive. Please don’t wriggle into me like that.”
“Don’t wriggle?” I huffed, trying to find a spot that wasn’t digging into him. “There’s no room not to wriggle!”
We hit a pot hole and it made me shift up and back down against him. My ass rubbed against is crotch as he whimpered beneath me.
“Ahh fuck!” he grumbled, shifting uncomfortably he gripped my hips all of a sudden and I felt something hard against my bum and pussy.
I froze, my eyes wide as I looked down at Adam. His face was flushed, his eyes locked on mine. “What the hell, Adam?” I hissed, trying to squirm away from him. But there was nowhere to go.
“Sorry, sis,” he muttered, his grip on my hips tightening slightly. “I can’t help it. You’re sitting on me in that short skirt, and you’re wriggling around. It’s… uncomfortable.”
I felt a blush creep up my cheeks. I couldn’t believe this was happening. My own brother was getting aroused by my sitting on his lap. I tried to shift my weight again, but it only made things worse. I could feel the hardness against my pussy, and I couldn’t help but feel a strange tingle in my own body.
“Just ignore it, okay?” Adam said, his voice strained. “It’ll go away eventually.”
I nodded, swallowing hard. I tried to focus on the scenery outside the window, but it was difficult with Adam’s hands still on my hips. The car hit another pot hole, and I shifted again, unable to help myself. This time, Adam let out a soft groan, and I couldn’t ignore the way my body was responding to the sensation. He rest his forehead against my back as there was another bump as I felt his dick rubbing against my gash.
I took my phone out of my handbag, and even though I was sat on his knee I had to text him. I didn’t want mum or dad to hear me.
I typed quickly, my thumb flying across the screen. “This is so weird, your thing is hard and rubbing against my you know,” I wrote, and pressed send.
My phone buzzed in my hand, and I looked down to see Adam’s response. “I know, sis. I’m sorry. It’s just… you look so good in that outfit. And you’re so close to me. I can’t help it.”
I took a deep breath, trying to steady myself. This was my brother, after all. We were family. But the way he was really hard under me, the way his hands were still gripping my hips… Every bump made my cunt tingle.
My hands shaking as I text back, “I can tell dad to turn the radio, do you wanna you know. I can ride it.”
My phone buzzed right away, “holy shit, really.” That is all he put with a wet emoji and a purple eggplant dick emoji too.
I shouted out, “Dad can you turn the radio up.” As I lifted off his lap a little enough for him to get his cock out. I lifted my skirt a little and pulled my knickers to the side.
Dad cranked the volume, filling the car with some old-school rock. The sudden blast of sound was exactly what we needed. I glanced back at Adam, his eyes wide and eager. My own heart thumped against my ribs.
I leaned forward a bit, wiggling, trying to guide him. It felt… huge. My mini skirt was practically up around my waist now, and the cool air from the car’s vents hit my bare thighs. Adam helped, guiding himself against me, and then, with a soft squish, he was in.
A gasp caught in my throat. It was tight, so tight, and a strange heat spread through me. Adam let out a low groan, his hands gripping my hips again, not gently this time, but firmly, possessively. His breath was hot on my back.
“Oh god,” I whispered, barely audible over the music. I didn’t dare move much, just settled fully onto him. Every tiny bump in the road, every sway of the car, sent a ripple through me. I could feel his hardness pressing deep, filling me in a way I hadn’t felt in a week.
He shifted slightly, his hips pushing up. My pussy tingled. This was so wrong, so messed up, but a part of me, the part that had been wanting Dan, couldn’t deny the rush. I leaned my head back against the seat, trying to look normal, like I was just tired. My cheeks burned. We were actually doing this, right here, in the car, with Mum and Dad in the front.
I started to rise up and down on his cock. Each small bounce made him groan, a low sound swallowed by the music. My mini skirt was bunched up around my waist, keeping my secret safe from Mum and Dad, who were oblivious to the insane thing happening just behind them.
Adam’s hands gripped my hips harder, guiding me up and down on his cock. It felt so wrong, but so good at the same time. I tried to keep my breathing steady, tried to look nonchalant, but my body was betraying me. I could feel a heat building inside me, a strange pressure that was both terrifying and exhilarating. I glanced over my shoulder at Adam, his eyes locked on mine, his face a mask of desire. I bit my lip, trying to hold back the moan that threatened to escape.
I leaned forward more, pressing my chest against the back of the front seat, trying to look normal. But inside, I was shaking. The friction, the fullness, the absolute shock of it all was overwhelming. He started pushing up harder, faster.
He started pushing up harder, faster. A sharp gasp caught in my throat, almost a whimper, as a sudden jolt went through the car. “Everyone alright back there?” Dad’s voice cut through the loud music, surprisingly close. I tried to answer as Adam kept beating his dick in and out out my snatch.
“Y-Yeah, ahh we… we are… fine!” I choked out, a little too loud, my voice thin. My cheeks felt hot. Adam paused for a split second, his breath catching, but then he started again, slower, deeper pushes that made me clench my teeth. My knickers rubbing against is shaft as his dick went in and out my wet twat.
Adam’s hands gripped my hips tighter, his fingers digging into the soft flesh as he started to move faster, harder. The car hit a bump and I let out a gasp, my pussy clenching around him as he thrust up into me. I could feel every inch of his cock, stretching me, filling me, making me feel so full it was almost painful.
“Mmm, fuck, Amy,” Adam groaned, his voice low and husky. “You feel so good, sis.”
I bit my lip, trying to hold back the moan that threatened to escape. My mind screamed at me, reminding me this was Adam, my brother, just metres away from Mum and Dad. But my body, oh god, my body was a traitor. Each thrust sent a shiver through me, a primal need that overshadowed every rational thought. My pussy was slick, hot, and stretched around him, desperate for more.
“Mmm, fuck, Amy,” Adam groaned, his voice low and husky. “You feel so good, sis.” His words, whispered against my back, sent another jolt through me, a mix of shame and intense excitement. His fingers dug harder into my hips, urging me to move, to take him deeper. He shifted slightly, his hips grinding against my lower back, pushing his cock in further with each movement. The sensation was intense, almost overwhelming.
I started to move more freely, a slow, deliberate rocking motion, mimicking the car’s gentle sway on the highway. My skirt was now a crumpled band around my waist, my bare ass sliding against the coarse fabric of his jogging bottoms. The cool air from the vents hit my flushed skin, a stark contrast to the burning heat between my legs. The music, a classic rock anthem, pounded in my ears, a perfect cover for our illicit symphony of gasps and muffled grunts.
“Oh, Adam,” I whispered back, my voice barely audible, thick with desire. I leaned further into the front seat, pretending to be utterly engrossed in the passing scenery, but my focus was entirely on the hard, pulsing length inside me. The rhythm built, faster and faster. His breath hitched behind me, and I could feel the tremor in his hands gripping my hips. I tightened my muscles around him, pulling him deeper, wanting every last inch.
The car hit a series of smaller bumps, causing me to bounce harder on him. Each jolt was a direct connection, a deeper thrust. A choked moan escaped my lips, quickly swallowed by the blare of a guitar solo. I pressed my forehead against the headrest, trying to compose myself, but it was useless. My body was taking over, chasing the incredible sensation that was building rapidly between my legs. The pressure was immense, radiating from my core. I could feel the blood rushing to my cheeks, my neck, my chest.
He moved his hands from my hips, sliding them under my skirt, his fingers brushing against the side of my bare ass, then the inner curve of my thigh. He squeezed gently, possessively. The simple touch amplified everything. My knees were pressed against the back of the front seats, my legs spread wide around him. I could feel the slickness of my own wetness running down my inner thighs, a tell-tale sign that I prayed wouldn’t be noticed if I had to move suddenly.
“Almost there, Amy,” Adam breathed, his voice ragged. I could feel the vibrations of his words through my body. He shifted his weight, adjusting the angle, aiming perfectly for my clitoris with each powerful thrust. The sensation was exquisite, a sharp, burning pleasure that threatened to rip a scream from my throat. I clenched my jaw, biting down hard on my lip. My vision blurred slightly, the passing trees outside the window becoming streaks of green.
Suddenly, Dad slowed the car, indicating for a turn off. “Just pulling into the service station for a quick break, kids,” he announced cheerfully, oblivious.
My heart leaped into my throat. A service station? Now? I froze, every muscle tensing. Adam, sensing my panic, paused his movements, his cock still deep inside me, throbbing. His grip on my hips tightened again, a silent reassurance. The car rolled to a slow stop in the parking lot, the engine quietening. The music seemed deafening now, covering nothing.
“Right then, everyone out for a stretch,” Mum said, already unbuckling her seatbelt.
Oh, god. This was it.
“Just… a minute, Mum,” I somehow managed, my voice a strained whisper. I couldn’t move. I was still impaled, my legs feeling like jelly.
Adam, surprisingly calm, shifted slightly, his hips pushing up one last, firm time. It wasn’t a full thrust, more of a deep, final press. That single, deliberate motion was all it took. A wave of pure, concentrated pleasure crashed over me, hot and intense. My hips bucked involuntarily, a silent shudder running through my entire body. My fingers splayed against the seat in front of me, gripping the fabric for support. My pussy clenched, milking him, and I felt the warm gush of his release deep inside me, flooding my already sensitive flesh.
A soft, almost inaudible groan escaped Adam’s lips as he too shuddered, his body going rigid behind me for a split second before relaxing. He gently pulled back, his cock sliding out with a soft schlick. The sudden emptiness was both a relief and a pang of loss.
“You okay, Amy?” Mum’s voice was closer now. I could hear her door open.
“Y-yes, Mum! Just… stretching,” I gasped, my voice still trembling. I quickly pulled my skirt down, trying to smooth out the wrinkles, my hands shaking. Adam was already pulling up his jogging bottoms, his face still flushed but his eyes clear, a faint smile playing on his lips. He passed me a tissue from his pocket, and I gratefully took it, wiping myself quickly, thankful for the discreetness of the car’s dim interior.
“Come on, Amy, let’s go get some snacks,” Mum called, her voice cheerful.
I took a deep, shaky breath, trying to calm my racing heart. My legs felt weak, my inner thighs still slick and tingling. I rearranged myself, trying to look normal, like I hadn’t just had my brother’s cock inside me moments ago. The radio was still playing, a gentle background hum now. I turned to Adam, meeting his gaze. There was a shared look of utter disbelief, exhilaration, and something else… something dangerous and thrilling.
“Coming, Mum!” I called out, my voice surprisingly steady. I opened the car door, stepping out into the bright daylight, feeling a strange mix of lightness and lingering intimacy. The world outside the car seemed utterly unaware of the secret we had just shared, a secret that would now forever bind us in ways I couldn’t have imagined. This long journey, it seemed, was only just beginning.
