The sun was unforgiving in the sky, its beams turning the ground into an oven and causing the air to waver with heat. The day we moved turned into a whirlwind of boxes and minor arguments, especially between Katie and myself. Katie, being the youngest, always chose the most inconvenient times to declare her independence, and today was no different.
Our car was packed to the brim, and with the trailer attached, space was scarce. Our parents took the front seats, leaving the tight backseat to us.
Katie, boldly dressed in a too-short skirt and a red t-shirt that matched her spirited nature, assessed the cramped space with increasing annoyance. “And where am I supposed to sit?” she asked, her tone edging toward confrontational.
Mom’s voice, calm amidst the turmoil, answered, “You’ll have to squeeze in next to Nathan or sit on his lap. We have to make it work, sweetheart.”
Frustrated and incredulous, Katie reluctantly perched on my knees. “This is absurd,” she muttered, clearly uncomfortable with the arrangement.
As we set off, the usual sibling disputes over music and the heat ensued. But as we drove further and the scenery blurred, a tense silence fell over us. Katie grew restless, her earlier defiance turning into discomfort.
Then, my phone buzzed. It was a message from Katie, sitting right on my lap.
“Why do I have to sit on your knee? This is so embarrassing,” her message conveyed her annoyance succinctly.
Holding back a laugh, I replied, “Because the car’s full. It could be worse, right? At least we’re not on foot.”
Her phone lit up, and I saw a flash of irritation turn into a grudging smile as she read my response. She quickly typed her reply.
“Yeah, sure. Because being squished against my annoying brother is my idea of a good time.” Her message said as she wriggled to get comfy. I decided not to text her just to ask her “Please stop squirming around on my knee.” I said to her as it felt weird feeling her bottom wriggle on my crotch.
Katie paused her movements for a moment, shooting me a look that was part frustration, part amusement. “Well, if you had less bony knees, maybe this wouldn’t be so bad,” she retorted, her voice carrying a hint of a tease. Despite the cramped conditions and the sweltering heat, there was a lightness to her words, a departure from our usual heated exchanges.
My phone buzzed, oh we are back to texting I see, “Why the fuck can I feel, you know your thing strained against my arse.”
My heart skipped a beat at Katie’s text. The car was filled with a tense silence as I read and re-read her words, unsure of how to respond. The weight of her body pressed against me in a way that was increasingly difficult to ignore, and I could feel the heat radiating from her.
I knew that I couldn’t acknowledge her text in front of our parents. But the thought of it made me feel a strange mix of discomfort and excitement. I tried to shift my weight subtly, hoping that Katie wouldn’t notice.
Finally, I mustered up the courage to type a response, making sure to keep my tone casual. “Uh, sorry, not much I can do about that,” I replied, trying to play off my reaction as best I could.
Katie’s phone buzzed again, and I waited anxiously to read her response. “I guess I’ll just have to deal with it, won’t I?” she typed, a hint of teasing in her words.
I felt my face flush as I read her text, and I tried to focus on the passing scenery outside the car. The heat was becoming almost unbearable, and I could feel my own discomfort growing with every passing moment.
The tension in the car was palpable as the miles dragged on. Katie shifted her weight again, her bottom pressing against my crotch in a way that made it difficult to ignore. I could feel myself growing aroused, despite my best efforts to push the feeling aside.
Another message on my phone, “I can feel it again, this is so weird having that pulsating against me, try to control it weird I can feel it against my you know, never mind.”
I couldn’t help but feel my cock twitch in response to Katie’s message. I shifted my weight again, trying to minimize the contact between us. But I couldn’t deny the growing arousal I felt.
The tension in the car continued to build, the silence punctuated only by the buzzing of my phone. I could sense Katie’s growing discomfort, but I wasn’t sure how to address it.
We still got a full day to go before we even get there and now my cock was raging hard strained and wanted to spring free. She moved again, this time she did it on purpose she then spoke up, “Dad” that’s when I thought, is that little bitch going to grass me up until she then said to him, “Can you turn the radio up.”
“Sure sweetie,” Dad responded, turning the radio up a notch.
The music washed over us, filling the car with a new energy. Katie settled into her position, trying to ignore the growing pressure between us. I felt my cock twitch again, the heat in the car making it even more difficult to control my arousal.
She got her phone in her hand again, my phone buzzed it was a message from Katie, “Haha aww am I teasing you” her text said as she moved her ass in circles and pressed down harder on me.
“Yes, you little shit please stop it,” I typed back, trying to keep my response casual. I could feel my face flush as I read her text, and I shifted my weight again to try and alleviate some of the pressure. But it was a lost cause; my cock was throbbing with arousal, trapped between the confines of my tight jeans and Katie’s firm, bottom.
I then got another text saying, “I ain’t going to lie I was disgusted at first but it’s rubbing against my panties and I like it, if I do something for you, you fucking owe me one.” With that said she slightly lifted and put her head between the two front seats of Mom and Dad, “turn this song up Dad,” she said as I could see up her skirt. Wait what did she mean do something for me?
I was about to text her until she sent another “Come on then idiot, I got him to turn the music up, lower me down when ready be quick.” Omg, she… did she really want me to… you know in the back seat while our parents were there.
I looked at our parents they were fixated on staring at the road ahead and singing to the music. My heart raced as I undid my button on my jeans and pulled my zipper down freeing my cock from my boxers. I gently moved her skirt up a little gently as I stretched her black panties to the side.
As I lowered Katie back down onto my lap, I felt my cock slide into her wet pussy. The sensation was intense, and I couldn’t help but let out a low groan. Katie’s body tensed for a moment, but then she relaxed, her breathing shallow and quick.
“Shh,” she whispered, her eyes darting towards our parents. “They can’t know.”
I nodded, my heart racing as I began to move my hips, slowly sliding my cock in and out of Katie’s pussy. The feeling was indescribable, and I couldn’t believe what was happening. My phone went off again as I continued to gently fuck her. The feeling of my dick sliding slowly in and out of her pussy felt mind-blowing.
Her text said “Oh my god, it feels so good. Don’t stop, Nathan. Fuck me harder,” her body moving in sync with mine. I held her hips tightly as she did like a little twerk as he pussy took my cock in and out.
I began to fuck her harder, the rhythm of our movements matching the beat of the music. My cock slid in and out of her wet pussy, the sensation almost overwhelming. Katie’s moans became louder, her body moving with mine as we lost ourselves in the moment.
The heat in the car was stifling, but it only added to the intensity of the moment. I could feel my climax building, my balls tightening as I thrust deeper into Katie’s pussy. She felt so fucking good, her body responding to mine in an almost primal way.
Suddenly, I felt Katie’s pussy clench around my cock, her body tensing as she was about to reach her climax. I could feel her wetness coating my cock, the sensation pushing me over the edge.
We stopped for a second as Mom turned to us “shouting over the music you two ok back there.”
“Yeah, Mom, we’re good,” Katie replied, her voice shaky. I could feel her trying to steady her breathing, my cock still inside her.
We resumed our movements, our rhythm in sync with the beat of the music. My climax was close, and I could feel my cock twitching inside Katie’s wet pussy. She started to twerk around my cock again this time a little faster. She whispered into my ear, “Fuck, I never knew you had a big one I could get used to this ah feels good.”
The music blaring from the speakers drowned out our moans and gasps, covering up the illicit act playing out in the back seat. I knew that I couldn’t hold on much longer, my climax building with each passing second.
Suddenly, I could feel Katie’s pussy clench around my cock, signalling her orgasm. She quickly put her hand over her mouth to stop herself as her pussy gushed and wet my lap.
It was too much for me, my climax crashing down on me like a wave. As I pushed my face into her back to muffle a deep grunt as I came hard inside her, “Argh,” my cock spasmed as I filled her pussy with my cum.
When I stopped pumping her she got up slightly as my cock fell out of her fully drained as I looked at her pussy. Looked very nice and especially with my creampie I just gave her.
I put my cock away and reached into one of the boxes beside us for a blanket and placed it over my soggy jeans from her squirting. She put her panties back to normal and sat back down. Then she got out her phone and moments after my phone buzzed, a message from Katie.
“Well, that was… unexpected,” her text read, her tone a mix of amusement and disbelief. “I guess we’re even now, right?” she added, a hint of a tease in her words.
The car journey continued, and the tension between us was replaced with a newfound understanding. Despite the cramped conditions and the sweltering heat, there was a lightness to our interactions, a departure from our usual heated exchanges.
As the miles stretched on and the landscape outside blurred, I couldn’t help but feel a strange sense of satisfaction. It was a moment of intimacy that I never expected, a shared secret between us that only added to the bond we shared as siblings.
That night in our new home it was late and Mom and Dad were asleep, I sneaked into my sister’s room.
I slowly opened the door to Katie’s room, finding her lying in bed with the moonlight casting an ethereal glow on her face. She looked peaceful, her earlier defiance replaced by a vulnerability that made my heart ache.
I approached her bed, my movements silent as I didn’t want to wake her. I sat down on the edge of her bed, looking at her for a moment before reaching out to gently brush a strand of hair from her face.
Katie stirred, her eyes fluttering open as she looked at me with a mixture of confusion and curiosity. “What are you doing here?” she asked, her voice barely above a whisper.
I hesitated for a moment, unsure of how to respond. But then, I took a deep breath and said, “I wanted to talk to you. About what happened in the car today.”
Katie’s expression changed, a hint of embarrassment flickering across her face. “I can’t believe we did that,” she said, her voice barely audible. “It was so wrong, but it felt… good.”
I nodded, understanding what she meant. “It was unexpected, but I can’t deny that it was intense,” I said, my voice equally quiet. “I don’t know what came over me, but I couldn’t resist the temptation.”
Katie looked at me for a moment, her eyes searching my face for any hint of judgment. But finding none, she said, “I felt the same way. It was like a moment of pure abandon, a release of all the tension and frustration that had been building up between us.”
We sat in silence for a moment, lost in our own thoughts. But then, Katie reached out and took my hand, her touch sending a jolt of electricity through my body.
“I don’t regret what happened, Nathan,” she said, her voice soft but determined. “It was a moment of connection between us, something that I don’t think either of us will forget.”
I nodded, squeezing her hand in response. “I feel the same way, Katie,” I said, my voice barely above a whisper. “It was a moment that I’ll always treasure, a reminder of the bond that we share as siblings.”
We sat there for a moment, lost in our own thoughts. But then, Katie leaned in and whispered, “Can I ask you something?”
I looked at her, my curiosity piqued. “Of course,” I replied, my voice equally quiet.
Katie hesitated for a moment, unsure of how to phrase her question. But then, she said, “Do you think we could… do it again? But this time, in a more… private setting?”
My heart skipped a beat at her question. I looked at her, searching her face for any hint of uncertainty. But finding none, I said, “If that’s what you want, Katie, then I’m willing to make it happen.”
Katie smiled, her relief palpable. “Thank you, Nathan,” she said, her voice barely above a whisper. “I know it’s wrong, but I can’t deny the attraction I feel towards you. And I think you feel the same way.”
I nodded, unable to deny the truth in her words. “I do, Katie,” I said, my voice equally quiet. “And I’m willing to explore this connection between us, as long as we’re both on the same page.”
I stroked her face and said, “Well Mom and Dad are asleep, want me to get into your bed maybe I can tire you out more for a better sleep.”
Katie’s eyes sparkled in the dim light, and she nodded eagerly. “Yes, please.”
I stood up quietly, making sure not to make any noise that would alert our parents. I took off my jeans and boxers, leaving them in a crumpled heap on the floor. My cock was still hard and ready for Katie.
I slid into the bed next to her, feeling the warmth of her body radiating through the blankets. Katie shifted closer to me, her body pressing against mine. I could feel her soft curves and the heat emanating from her pussy.
I wrapped my arm around her, pulling her closer to me. Katie rested her head on my chest, her breath hot against my skin. I could feel her heart beating rapidly, matching the rhythm of my own.
We lay there in silence for a few moments, enjoying the closeness and intimacy between us. But the tension was building, and I knew we both wanted more.
I moved my hand down to Katie’s thigh, slowly sliding it up under her nightgown. Katie shivered as my hand made contact with her skin, her breath hitching in her throat.
I continued to move my hand up, feeling the softness of her skin and the heat emanating from her pussy. Katie parted her legs slightly, allowing me easier access.
I gently stroked her pussy through her panties, feeling the wetness seeping through the fabric. Katie moaned softly, her body writhing against mine.
I slipped my fingers under the waistband of her panties, slowly pulling them down her legs. Katie lifted her hips to help me, her breathing shallow and quick.
Once her panties were off, I moved my hand back to her pussy, Katie moaned louder as I stroked her clit, her body writhing against mine.
I moved my fingers down to her entrance, feeling the heat and wetness of her pussy. I gently pushed my fingers inside her, feeling her walls contract around them.
Katie moaned loudly, her body bucking against mine. I began to move my fingers in and out of her pussy, building up a rhythm. Katie matched my movements, her breathing becoming ragged.
I increased the pace, finger fucking Katie’s pussy harder and faster.
Katie’s moans filled the room, her hips bucking against my hand as I finger-fucked her with reckless abandon. I could feel her pussy clenching around my fingers, her wetness coating them as I plunged them deeper inside her.
“Oh fuck, Nathan,” Katie gasped, her fingers digging into my arm as she held on for dear life. “I’m so close, don’t stop.”
I had no intention of stopping. I wanted to make Katie cum harder than she ever had before, to show her just how good it could be between us.
I could feel my own arousal building, my cock throbbing painfully as I watched Katie writhe in pleasure. I wanted to be inside her, to feel her pussy wrapped around my cock as I fucked her with everything I had.
But for now, I was content to make her cum with my fingers. I could feel her walls tightening around me, her breathing becoming ragged as she approached her climax.
“Oh fuck, oh fuck, I’m gonna cum,” Katie gasped, her body trembling as she reached the edge.
And then she did, her pussy clenching around my fingers as she came with a loud, guttural moan. I could feel her wetness coating my hand as she rode out her orgasm, her body shuddering with pleasure.
I slowed my fingers, letting Katie come down from her high. She looked up at me, her eyes glazed with pleasure and her lips swollen from our kisses.
“That was… amazing,” she whispered, her voice hoarse from her orgasm.
I smiled, feeling a sense of satisfaction wash over me. I had made my sister cum, and it had been even better than I had imagined.
“I’m glad you enjoyed it,” I said, brushing a strand of hair from her face. “I want to make you feel good, Katie. I want to give you pleasure like you’ve never experienced before.”
Katie smiled, her eyes shining with gratitude. “You already have,” she said, snuggling closer to me.
We lay there in silence for a few moments, enjoying the closeness between us. But I knew I couldn’t wait any longer. I needed to be inside Katie, to feel her pussy wrapped around my cock.
I moved my hand from her pussy, sliding it up to her breast. I cupped it gently, feeling her nipple harden under my touch. Katie moaned softly, her body responding to my touch.
I moved my other hand down to my cock, stroking it gently as I watched Katie. She looked up at me, her eyes heavy with desire.
“I want you inside me, Nathan,” she whispered, her voice barely above a whisper.
I didn’t need any more encouragement. I moved over her, positioning my cock at the slit of her cunt.
I pushed inside her, feeling her pussy resist at first before giving way. Katie moaned loudly as I filled her, her pussy clenching around my cock.
I started to move, slowly at first before building up a rhythm. Katie matched my movements, her hips bucking against mine as we fucked.
The room was filled with the sound of our bodies slapping against each other, our moans and gasps echoing in the darkness. It was primal, raw, and intense.
I started to fuck her harder, my balls slapping against her arse as I pounded her pussy. Katie’s moans grew louder, her fingers digging into my back as she held on for dear life.
I could feel my orgasm building, my balls tightening as I approached the point of no return. I didn’t want to cum yet, I wanted to make this moment last as long as possible.
But Katie had other ideas. She wrapped her legs around my waist, pulling me deeper inside her. I could feel her pussy clenching around my cock, her walls milking me as she approached her own climax.
“Oh fuck, Nathan, dump your load in me,” Katie gasped and moaned I add to put my hand over her mouth as I hammered her cunt.
I couldn’t hold back anymore. With a final thrust, I exploded inside her, my hot cum filling her pussy as she milked every last drop from me.
We lay there in silence for a few moments, our bodies spent and sated. I pulled out of her slowly, feeling her pussy clench around my cock as I left.
Katie looked up at me, her eyes shining with gratitude and satisfaction. “Thank you, Nathan,” she whispered, her voice hoarse from our lovemaking.
I smiled, feeling a sense of contentment wash over me. I had made my sister cum, and it had been the most intense experience of my life.
“You’re welcome, Katie,” I said, brushing a strand of hair from her face. “I’m glad I could make you feel good.”
We lay there for a few more moments, enjoying the afterglow of our lovemaking. But eventually, I waited for her to nod off before I went back to bed.
I got out of bed slowly, making sure not to wake Katie. I pulled on my clothes, feeling a sense of satisfaction as I looked at her sleeping form.
I left her room, closing the door quietly behind me. I made my way back to my own room, feeling a sense of contentment and happiness that I hadn’t felt in a long time.
I crawled into bed, feeling the warmth of the blankets around me. I closed my eyes, drifting off to sleep with a smile on my face.
I had found a new connection with my sister, one that would change our relationship forever. And I couldn’t wait to see where it would take us.
