Brother Sister Story I
“Okay, long drive today,” My Mum said as I put a third suitcase into my car. “How long do you think you can go without stopping?”
“I can go for hours,” I replied. “It’s Grace who will need to stop to pee every 5 minutes!”
“Shut up!” Grace shouted from the front door of our house.
“You two better not be arguing the entire drive there, or we will swap who’s in which car!” Our Mum sighed.
“Yes, Mum.” Grace and I replied in unison.
My car was filled with suitcases while our Mum and Dad’s was filled with food. We were all set for our family weeklong holiday. We were driving to the other side of the country, but it was a drive I was not looking forward to.
Grace opened the passenger side of my car, as she stepped in, and I couldn’t help but gaze at her shapely arse hidden by her tight, blue jean shorts.
“Right, see you later.” I said to my Mum as I got into the driver’s side.
“Ready?” Grace asked.
“Yep, let’s go.” I replied.
—
We were an hour into our road trip.
On the motorway my Mum and Dad had sped off, given that their car was much nicer than mine.
In my car was me driving and my sister, Grace, in the passenger seat. I was 20, and Grace was 18, and we were as close as most brothers and sisters were. She was nice, if a little annoying and more wild than me. However, it was impossible to not notice how Grace had come into her body since turning 18.
She had long blonde hair that shined like the sun, and although she had a slim frame, her chest had become more and more noticeable as of late, especially as she was wearing a loose white vest that blew in the wind, revealing her white lacy bra underneath.
Occasionally I would look across the car and see underneath her vest and get a glance at her cleavage. Yes, it was wrong that I would look at my younger sister like that, but she was hot!
She was sat on her knees, wearing blue denim shorts that stopped very high up her thighs. Grace’s legs weren’t long, but they were toned and smooth, the sort of legs that forced you to stare at them.
More than once on the drive, I accidentally swerved across a lane as I got distracted by her.
“I’m so bored!” Grace moaned, her blonde hair blowing back due to her open window.
“Well, there’s another three days of driving, so get used to it.” I told her.
I didn’t expect this drive to be fun, but being in such close quarters with my sister, whom I was massively attracted to, was making it even harder. With each glance over I panicked that she would catch and ridicule me.
That was until her hand suddenly reached across and took a handful of my crotch.
“Wooah!” I shouted and swerved the car. “What are you doing?!” I shouted, getting the car back between the lanes.
“You’ve been staring at me since we got in the car,” Grace told me. “I was seeing if you were hard.”
Her fingers remained gripped around my growing cock, blocked by my jeans.
With my eyes on the road, I had a quick look down, and Grace’s fingers were tightening and loosening around my cock that was getting harder and harder.
“You alright there?” I asked sarcastically.
Her hand moved away, and I immediately regretted saying anything.
“Not as good as you are apparently.” Grace joked.
Her window slowly rose up until it closed, but I didn’t realise how silent the car was without the window open and the air blowing in.
Grace pulled her hair back behind her head and stretched, her chest pushing up in front of her, and I couldn’t help but look over.
“You’re so easy to tease.” Grace laughed out.
“You’re the one practically shoving your tits in your brother’s face.” I joked back.
“You’d like that, wouldn’t you,” Grace said with a half smile. “Your sister shoving her tits in your face.”
I glanced at her again to see a cocky grin before looking back on the road.
“I wouldn’t say no.” I replied, smiling at myself.
“Perv.” Grace joked.
The car went deathly quiet after that. We had always been comfortable with each other, but something felt different now, as though we had crossed a line and didn’t know how to act.
“Fine.” Grace sighed.
My head turned to the side and back to the front constantly as Grace sat forward.
“What are you doing?” I asked, seeing my younger sister moving in the corner of my eye.
“What you asked for.” Grace replied back, and the seriousness in her voice both frightened and excited me.
Still trying to watch, Grace grabbed the hem of her loose vest and effortlessly pulled it over her head before throwing it to the floor by her feet.
My cock jumped as my sister sat next to me in her bra. I cursed the fact that I had to focus on the road, wishing I could properly look at her cleavage.
That was until I noticed her bra being pulled forward. One of Grace’s arms straightened, and I saw her bra drop on top of her vest.
I quickly turned my head, and I saw them. It was just a glance, but Grace’s bare chest was out. They were glorious! Even with only quick looks, I could see their perfect shape and size.
“Are they real?” I asked since they looked too perfectly positioned to be real.
Two silky smooth spheres were attached to her chest, bouncing slightly with each movement. The weight of them made them fall down only slightly, but age was on her side. Perfectly placed were her stiff nipples, and her areolae were large and soft to look at.
“Yes, they’re real!” Grace shouted and slapped my arm.
In the corner of my eye, I could see them bounce, and what I would’ve done to reach across and take her globes into my hands.
Instead, I had to settle for watching Grace’s tanned fingers hold onto them. Her fleshy breast pushed between each of her fingers, her stiff nipple poking through a gap as she pulled on them.
“You know people can see in, right?” I said, noticing plenty of other cars on the motorway.
“Aww, are you shy?” Grace mocked, the little tease!
“Oh, I’m not shy,” I told her. “I just didn’t realise what a slut my sister was.”
“A slut now, am I?” Grace argued. “Well, if I’m a slut, then I’d better be a good slut.”
I could see her playing with her big tits next to me, pulling at her firm, pale nipples. My cock was now at full attention in my jeans, desperate to be freed.
“Would a slut finger herself in a car while sitting next to her brother?” Grace then asked me.
My mouth instantly filled with saliva. Was she being serious? She had always been jokey and sarcastic, but I really couldn’t tell.
“Oh, I guess not.” Grace then said when I didn’t reply, knocking some sense into me.
“Actually,” I replied and saw a smirk on the side of my sister’s face, “a real slut would take all her clothes off before fingering herself, so anyone driving past could see.”
Grace must have been surprised by my comment as for the first time in her life she was silent.
“Fair enough.” She said as her hands went to the button on her jean shorts.
My heart was beating faster than my car as I tried to both watch Grace and the road. I could see when her button was undone, and she unzipped her shorts.
Lifting her firm arse from the seat, Grace pulled the denim material down her luscious legs and kicked it off by her feet.
There she was, completely naked while sitting next to me. From my angle I could just see her pelvis, but her legs were closed, making it so I couldn’t see her sex hole.
Slowly, Grace parted her legs until her knee hit the gear stick in the middle. Fuck, I still couldn’t see between her legs.
I couldn’t believe that my 18 years old full-bodied sister was completely naked with her legs spread next to me.
“Mmm.” She mewed in a high pitched, hushed voice.
I turned my head, and my eyes nearly burst from my skull when I saw her right hand between her legs, moving slowly!
“What?” Grace said in a cheeky voice. “You told me to finger myself.”
Her hand was moving around, clearly circling her clit. I could only imagine the beauty of her lips moistening with every passing second.
A car overtook us, and I watched the man in the passenger seat looking into our car. His face turned from regular to shocked and then to a smile, which made me laugh. To my side, Grace was smiling at him, using her right hand to massage her clit while her left played with her left breast.
Grace’s high pitched quiet moans mixed with her heavy breathing, sending me wild. My car was quickly heating up as her passenger window began to fog up.
“But right now,” Grace whispered and bit her thick, bottom lip, “I’m just rubbing my clit… this is fingering myself.”
Her left foot went onto the dashboard. I saw her perfect, smooth foot with pink painted nails. Her left knee bent as my eyes worked their way down her thigh. I still couldn’t directly see her pussy, but I saw two fingers press inside of her.
“Mmm, that’s better.” Grace moaned.
A car on our left beeped, and we both jumped, but Grace didn’t stop.
“I guess you are a slut.” I whispered with a grin.
“I guess I am.” Grace replied.
Her two fingers moved in and out of her hole, and I could see her bare foot moving in circles as she fingered herself. From the corner of my eye, I could see Grace’s large chest heaving up and down as her pleasure grew.
My own cock was at an awkward angle, so I lifted myself up from my seat to reposition it to facing up, and this got Grace’s attention.
“Does watching your sister finger herself get you hard?” Grace asked.
“Why don’t you find out for yourself?” I replied cockily.
How wrong this situation was only made it hotter.
Grace’s thin fingers left her little hole, and they glistened in the sunlight before she sat upright again. Her breasts bounced with her movement as she turned towards me.
Her right leg went underneath her, her right knee pressing against the back of the seat as her left foot went back onto the ground of the car.
I turned my head and gasped… finally, I saw it. And it was hypnotic. I had seen a few girl’s pussy in my time, but none were like Grace’s. She had lips that were perfectly placed, as smooth as they could be, and moist from her own juices. My mouth drooled at the sight, and the thought of even touching her sent me wild.
That distracted me until Grace’s hands grabbed onto my belt.
“Woah!” I shouted.
“What, you told me to find out?” She said in a girly, playful tone.
I expected her to simply grab my shaft, not to take it out, but I wasn’t going to refuse her.
Grace easily undid my belt, and her fingers went to my zipper. As she pulled it down, I lifted my arse from the chair, and Grace grabbed onto my jeans and pulled them down.
My aching, hard cock bounced freely, tapping against the steering wheel with precum coating the tip.
“Well,” Grace said to me, “I was not expecting that.”
“What?” I asked, a little nervous now that she had seen my cock.
Then I felt her warm fingers wrap around my shaft tightly, and I throbbed into the palm of my little sister.
“I didn’t think you’d be this big.” She told me.
Her right hand slowly pulled down, and the helmet of my cock pulled down with it before she stroked it back up and squeezed out a little more precum.
“You thought I’d be small?” I asked, a little offended.
“Not small,” Grace corrected, “just, I didn’t think you’d be this big!”
As her warm, delicate hand motioned up and down on my girth, my own breathing began to quicken in pace. Was my sister seriously giving me a handjob?
My cock twitched in her hand as she pulled the entire length to its base and back up to the head.
“You seem to know what you’re doing.” I told her.
I had no expectations that my sister would be a virgin, however she was only a few months past 18, so I didn’t think she would be too knowledgeable.
“Oh, I know exactly how to make a big cock cum.” Grace told me, her voice eradiating with seductiveness.
“Is that what you’re doing here?” I asked hopefully.
Grace increased her pace of stroking my pole, her hand grazing against my abs occasionally.
“Is that what you want?” She asked me, again putting on her girlish voice. “Do you want your little sister to make you cum?”
I smiled, keeping my eyes on the road as I attempted to look at her from the corner of them.
“My little sister is going to make me cum.” I told her firmly.
She giggled at my answer, and her hand pulled away. I panicked, wondering did I take it too far? But then I saw her take the hairband from her wrist and tie her blonde hair back.
“Have you ever had road head before?” She asked me.
I gave a confused look, that not being a term I had heard before.
“It means having your cock sucked as you drive.” Grace said bluntly.
My cock jumped at that.
“No, but I’m always open to trying new things.” I told her.
Was my sister actually going to suck my cock?
But then she undid her seatbelt, and my heart skipped a beat. This was happening! She got onto both knees, her calves going under her arse as she faced me. Once again, I looked at her bouncing tits.
“You focus on the road,” Grace told me, “if I die with my brothers cock in my mouth, there will be some serious questions.”
“You really think you’re good enough to distract me?” I cockily replied.
“Oh Ben,” Grace said, her head moving towards my stomach, “just you wait and see.”
My sister’s blonde hair came into view as I saw the back of her head, and I was only gutted that I couldn’t watch properly. But when I felt a warm, wet mouth engulf around my head, I let out a loud, heavy moan.
“Fucking hell.” I grunted. She was seriously doing it. My sister was sucking my dick!
To my side, I could see her arse in the air, pointing at the window, a perfect heart shaped behind. A car drove past, and I was jealous of the view they got of my sister’s pussy and arsehole!
“Jeessuuss Christ!” I moaned as Grace lowered her mouth deeper onto my cock.
Her lips were heavenly, and they felt moist, soft and plump in the most desirable way. How she wrapped them around my hard meat sent my head wild, and I did in fact find it hard to focus on the road.
Her soft, wet tongue pressed against the tip of my cock, sliding across my slit, sending shivers of pleasure throughout my body.
“Mmmm.” Grace moaned around my cock, making the rest of my length vibrate.
This was already by far the best blowjob I had ever received. Then her head pulled up, and cold air hit my glistening, spit covered cock.
“Sorry,” She whispered, “it’s not the best angle. Next time if we’re in the proper position, I’ll take you down my throat.”
Fucking hell! What happened to my sister?!
I went to reply, but her lips around my cock took me by surprise, “Oooooh that’s okay.” I moaned.
Her gentle tongue swirled in circles around my head, examining every inch. Grace’s left hand went down to my balls, cupping them and stroking them gently.
“Fuck, Grace.” I moaned.
I thanked God that I didn’t need to change gears and interrupt this incestuous blowjob.
“Mmm.” Grace moaned around my cock, and then her head pulled up with a pop. “Your cock is delicious.”
“I’m glad you think so.” I said with a laugh.
Her left hand played with my heavy balls as her right hand began to stroke up and down my spit covered cock.
“You’ll think the same when you taste my cunt.” Grace told me, proving that she wanted to take this further.
“Oh, I can imagine.” I replied.
All I wanted to do was close my eyes and enjoy her pleasing my cock, stupid driving!
The car on our left beeped, and two lads were looking in, clapping and cheering. Grace turned her head and looked past her bare arse towards them.
“I’m sucking his dick!” She shouted before turning back to me.
“You’re fucking nuts.” I joked.
Her hand gripped my wet shaft tighter as she wanked me.
“Give me a warning when you’re gonna cum,” Grace told me. “I’ll swallow, but give me a heads up.”
“Okay.” I panted.
Grace flicked a few loose strands of her blonde hair back before leaning back down.
“Fuuucking hell!” I moaned once more as her thick lips gripped around my member.
Up and down her blonde head moved, taking more of my cock than I ever imagined possible.
“Mmmmm!” Grace kept moaning around my cock.
As she took me deeper, feeling her throat wrap around my cock, I felt her tongue run against my sensitive, smooth skin.
My left hand that wasn’t in use landed on top of her head, and my fingers mixed into her silky blonde hair.
Grace opened her mouth wider, and I felt her head go down lower. More of my shaft was filled with warmth from the inside of my mouth as she took me deeper and deeper.
“Gllg!” Grace gagged, and her head pulled up. “Fuck, thought I could take more.”
“Just need practice.” I joked.
She turned her head and looked up at me. Her lips were gleaming with spit as she smiled, her shining white teeth on show.
“Good point.” She replied.
My sister’s head turned back around and went back to sucking on my dick. This time she was going at it like a wild animal. Her head bobbed up and down violently, mixed with her own slutty moans.
The silent car was now filled with my sister slurping around my dick.
I needed to feel more of her, so my left hand left her head and moved onto her smooth, toned back. Grace had an amazing back, smooth skin without a single imperfection. I kept creeping my hand lower down her back as she guzzled on my cock, and I eventually reached the top of her arse cheeks.
Pushing lower, I aimed to reach her pussy. Grace must have known as she moved her body forward, getting me closer. My hand sunk lower, and my fingertip pressed against her smooth, tight arsehole.
“Mmmff!” Grace gasped around my cock before pulling back out. “Don’t even think about it!”
I smirked, looking at her.
“I thought you were a slut?” I asked as her right hand was wanking my cock.
“I am,” Grace laughed back, “but your massive cock is not going in my arse!”
“We’ll see.” I joked.
Grace laughed before taking me back into her mouth.
I rubbed her little puckered hole and felt her growl around my cock. I laughed to myself, but I wasn’t about to finger my sister’s arsehole if she didn’t want me to.
I reached further down as Grace pushed her hips forward, and then I felt it. My fingers touched her wetness. Her warm, thick juices covered her soft, smooth pussy lips. Fuck, they felt good!
As much as I could reach, I wasn’t able to reach far enough to properly rub her clit.
Instead, I rubbed my finger around her lips until I found her tight hole and slowly pushed it inside of her.
“Mmm.” Grace moaned around my cock as I sunk my finger to the first knuckle.
I hated the fact that I couldn’t finger her properly, but I did the best I could. Three quarters of my finger was inside of her pussy, pushing in and out, feeling just how tight her cunt was as it clutched onto my finger.
“Mmmmm!” Grace moaned again as I fingered her.
Her mouth never stopped working either, going up and down on my cock. Occasionally Grace would gag, but that never stopped her.
Steam began to cover the front window of my car. Quickly moving my one hand from the steering wheel, I turned up the air con which quickly demisted the car.
Then I went back to looking at the road while I enjoyed this amazing blowjob as I lightly fingered my sister.
Until her mouth pulled back up, but she kept her lips near the head of my cock.
“Okay, the fingering is just teasing me,” Grace moaned. “Let me focus on your cock, and then you can make me cum properly when we stop.”
“Fair enough.” I replied.
Her pussy gripped around my finger as I pulled it out. Staring at the shiny finger coated in my sister’s juices, I couldn’t resist pushing it into my mouth. I tasted my sister’s pussy, licking my finger clean as she put her sole focus on making me cum.
Up and down her head bobbed, moaning and gagging around my cock.
As I just focused on the blowjob, I soon felt my balls begin to tighten in her hands.
“Okay, I won’t last much longer.” I warned.
“Mhmm.” Grace moaned back as she kept deep throating me.
My cock began to twitch in my sister’s mouth as my legs twitched. My body tensed, and I struggled to keep my eyes open as my orgasm hit me.
“Fuuucckkkk!!” I roared out as my cock expanded and fired into my sister’s mouth.
“Mmmm!!” Grace moaned as I coated her tongue.
Shot after shot of my thick creamy cum filled her mouth. It seemed to never end. My body twitched, my cock pulsated, and Grace kept on taking my cock down her throat.
It was the largest load of cum I had ever released, and Grace didn’t miss a single drop. She let every bit of my cum swallow down her throat and continued to moan around my shaft.
“Mmm.” Grace moaned as my body stopped shaking.
Her wet tongue continued to swirl my sensitive, stick head. With one last deep throat, she pulled back and sat back in her seat.
“Mmm, got to say, you have delicious cum.” Grace said as she pulled the seatbelt over her naked body.
Although my balls had been thoroughly drained, I still admired her big tits being pressed by the seatbelt.
“Well,” I said as I pulled my jeans back up, “that just happened.”
“Oh please,” Grace joked, “You’ve been staring at me ever since I turned 18.”
My face reddened.
“You noticed that?” I asked.
“You’re not exactly subtle.” Grace joked.
I couldn’t help but laugh. Was I really that obvious?
“How long until we stop?” Grace asked me.
“Not sure, a few hours, why?” I asked back.
“Because I’m horny as fuck, and you owe me one!” She said and giggled.
My cock began to stir again at the thought of making my younger sister cum.
“I suppose I can agree to that.” I told her.
Our brother and sister relationship definitely had taken a turn. Maybe this road trip wouldn’t be as boring as I thought it would be.
To be continued…
