Road Trip Sister

"Mu-um, Callum has eaten all of the pancakes again," I said in exactly the kind of sing-song, petulant voice that I knew would annoy him the most.

"You said you didn't want the last one," he replied angrily, pointing to my plate which still had half an uneaten waffle on it.

"I never said I didn't want it," I argued back. "I said I might want it if I was still hungry."

"But you're obviously not still hungry, look at your plate."

"Kids," Mum said in a stressed voice. "We're supposed to be having a nice time on holiday."

"How am I supposed to have a nice time on holiday if Callum eats my pancakes?"

"How am I supposed to enjoy myself if Evie keeps whinging like a brat?"

I made a shocked face and Mum turned on Callum.

"Don't call your sister a brat. Evie, honey, you can have an extra pancake tomorrow morning. Callum, you can help me with the washing up while Dad sorts out the water."

Callum groaned. "I washed up last time."

"You should have thought of that before eating your sister's pancake."

"Now who's being a brat?" I said to him, grinning. He gave me the finger, but unfortunately Mum was looking the other way.

My breakfast finished, I set about relaxing while Mum made Callum help her with the dishes. The RV Dad had hired for our 'last ever proper family holiday' was gigantic, about three times the size of anything you'd be allowed to drive back in the UK. So I was able to hide myself away on the sofa, putting my bare feet up on the cushions and getting out a book, far away from Callum's wrath. I'd rather have gone on my phone, obviously, but Dad had completely banned phones from the holiday in favour of 'family bonding'. Look how that was going.

"Right, everyone, we're all set," Dad said, climbing back into the RV. "In an hour we should be pulling into Fayenneston, Minnesota!"

Nobody mustered much of a cheer. We'd been going more than ten days, touring around the Great Lakes region, but whilst I had pictured a US road trip to mean bright lights in Vegas or luxury relaxation in LA, Dad had opted for small-town charm and backwater attractions. 'The Real USA' he called it, but I don't know what he would know about it, since he'd spent his entire life living in Bedford. He was just one of those people who could be enthusiastic for anything, no matter how mundane.

"Don't all jump up at once," he muttered, getting into the driver's seat.

"We're done with the dishes," Mum announced, and Callum raced off to the back of the RV immediately, as far away from me as he could get. He wasn't a reader; I didn't think he'd brought a single book with him. His real love was playing rugby, which he did for his university first team, but when he couldn't do that (like when he was touring around a country which had barely heard of it), he just played computer games on his handheld PC thingy. I thought that was childish and had told him so several times.

"Fayenneston is home to the US National Museum of the Self-Propelled Crop Sprayer," Dad said proudly, pulling out of the campsite now that Mum was safely seated. "It was invented in Minnesota."

"Sounds really interesting," Mum said bravely. I knew she wasn't interested in self-whatever museums, but she did love Dad and liked going along with his whims.

"Count me out," I said flatly. "I'll stay in the RV and read."

"Suit yourself," Dad said. He'd long since stopped battling with Callum and I about what we did and didn't do. "We could do with a few more supplies, though, so either you or Callum will need to go into town to buy them."

"Bagsy not me." Callum would have his headphones on for gaming so he wouldn't hear until later.

"You can both go," Mum said firmly. "Last time we sent Callum on his own he forgot half the things we needed."

I sighed. "Fine. But you know, he's twenty-one and he manages fine when he's at uni. He's just pretending he's useless so you won't ask him to do things."

"Evie, you're almost nineteen and manage fine when you're at uni," Mum added, so I went back to my book, pretending I hadn't heard her. That was the reason for the holiday: Callum had already got a job lined up for the summer now he'd graduated, so from then onwards we might not all be free at the same time. I thought I was too old for family holidays with my parents and brother, but this one had been compulsory. I couldn't wait for two years' time when I could graduate and live completely independently.

The truth was, Callum really wasn't that bad. It was just fun to wind him up and set him going, and both of us needed a bit more space than afforded by the RV, where we basically all slept in one room. Once Dad had pulled up in the car park of the museum and Mum had given us some cash and a shopping list, we were on our own. And in the warm spring sunshine Callum didn't feel so much like an annoying older brother. I was pleased I'd opted for a t-shirt and jean shorts, because it was almost getting hot.

"I say we buy everything as cheap as possible, dump it back here, then spend the rest of the money," he said, counting the notes. "There's got to be somewhere fun to hang out even in a town like this."

We'd seen enough 'small towns' on the trip to know that they were broadly the same, with similar shops and coffee places. I would be completely happy drinking coffee all morning and watching the locals doing their shopping, moving their cars twenty yards down the road to go into another shop instead of just walking.

"Works for me," I told him.

"If you can stop being a brat for long enough."

I knew he'd still got an insult in there somewhere. He didn't like it when he didn't get the last word.

"It's you that's the brat," I replied sweetly.

"Why don't you just go back to the RV and read your book? I don't need this hassle."

"I would, but Mum is making me go with you because you're too stupid to follow a shopping list."

He looked over at me. Callum had inherited Dad's genes: tall, dark hair, athletic. On the other hand, I was more like Mum: petite, blonde and perky. We were so different that people had a hard time telling that we were related, although there were a few similarities when you looked closely. For fun I sometimes wondered what it would be like if we'd had the opposite genes: I could be a fast rugby player on the women's team, and he would probably be a gaming geek or something.

"American shops are confusing. They call everything something different to what we call it," he explained. "What the hell is 'cake flour'?"

"Probably the flour you use to make cakes, dumbarse."

"How would I know what that was? I don't fuck about in the kitchen making prissy little cakes like you do."

"Why do you think I make cakes? I haven't made a cake since I was about nine."

"I don't know, it's a girl thing, isn't it?"

"So now you're being sexist. Awesome work, Callum."

"Fuck off, Evie."

Did I say Callum didn't feel so annoying out of the RV? Clearly I was wrong.

When we'd walked the quarter of a mile into town and found somewhere to cross the road, the place was weirdly busy. There were cars parked everywhere and big banners draped between buildings, and you could hear a marching band or something playing in the distance.

"'June Jarl Festival'," Callum read off a banner. "What the hell's this?"

I spotted a flyer advertising it and went over to look at it. "'Celebrate our town, June 1st, with a festival of all things Minnesota. Bring your Viking spirit. Food and drink stands, prizes to be won.'"

"It's the first today. So it's some kind of event?" Callum asked, looking at the rows of cars and the blocked street.

"Well done Sherlock."

"Do you want to have a look? I didn't really get enough breakfast so I wouldn't mind some more food."

"You literally ate my pancake and now you're still hungry?"

"You weren't hungry. You said I could have it."

"No I didn't."

We were still bickering on that topic when we reached the main street where everything was set up. Crowds of people were milling around, walking up the street which was lined with the usual types of food truck: burgers, pizzas, hot dogs and so on. A bit heavy for the morning, I thought, but Callum handed over some money in return for two corn dogs.

"Americans do food right," he said in between chews. "Lots of meat."

"Just seeing you eat that is turning me vegetarian."

At the other end of the street, which we strolled up towards, there was an area set aside for fairground rides, children's entertainment and so on. Neither of us was in the mood to be spun around by a clearly unsafe-looking ride, so we kept going, eventually finding a group of people who looked like they were getting set for a marathon or something.

"What's this?" I asked, curious, loud enough to be overheard by an overweight bloke sitting behind a table nearby.

"Fayenneston fifth annual wife-carrying race," he declared in that typical overly loud way that Americans liked to talk. "It's a traditional Viking art, going back centuries."

Callum snorted. "Wife-carrying?"

"It's easy, son. You pick up your wife, or girlfriend or buddy or whoever, and you have to run the course. Fastest pair wins one hundred dollars cash."

"One hundred?" I repeated, impressed. Egg-and-spoon races in the UK usually came with a plastic trophy and nothing else.

"You heard me right. Second place is a fifty, and third gets twenty-five. You interested?"

Callum shook his head. "Nah, not really."

The man looked affronted. "You all are the perfect couple for this! You look like you play football, son. What are ya, quarterback?"

"We're English. I play rugby," Callum explained, looking embarrassed.

"Rugby, huh, well I've heard of that. Still a game for big tough guys, right? And your girlfriend here is so tiny you'll barely notice you're carryin' her. I reckon you'd have a decent shot."

Callum was turning redder by the second and I saw my chance.

"Come on, it'll be fun," I said, grinning. "Do it for your girlfriend? Pleeeease?" I tugged the sleeve of his shirt.

"Well now son, you can't say no to this pretty lady. It's five bucks to enter and I just need your names."

With a face like thunder, Callum looked at me. "No way. Stop fucking around," he said, in a low voice that the man couldn't hear. "You're not my girlfriend."

I just giggled. "Okay, I'll sign us up," I said, walking up to the man with my biggest smile. He beamed back at me and handed me a printed sheet of paper, and I'd automatically written 'Evie Grange' before realising that we could hardly put the same surnames down. So instead I wrote 'Callum Borg' and made myself laugh. Then I elaborated it into 'Borgenssen' on the Viking theme and handed the sheet back.

"Borgenssen, huh? Well that's fantastic, you must have some real viking blood in you," the man said to Callum. "Just the five dollars and I'll let you have your equipment."

Unable to back out now, Callum handed over the money, still looking daggers at me. This was going to be so funny.

The man gave Callum a belt, which he could use to help support my weight, and sized me for a helmet in case Callum dropped me. I didn't really want to wear it, since it would mess up my hair, but the other 'wives' all had theirs on so I just bit the bullet.

Hanging around in the sun for the official start time of the race was boring, but Callum was getting drawn in by the competitiveness. The course was laid out along the road: there were hay bales to climb over, a rope bridge, a muddy section on a big tarpaulin, that kind of thing. More of an obstacle course than a race. He looked it all over, mentally planning.

"How are you going to carry me?" I asked out of interest.

"Piggyback, I suppose. Or maybe fireman's lift, if I don't need my arms free."

"Sounds like you're actually enjoying this," I teased him, and he shook his head.

"I'm not. But a hundred dollars is a lot of money and most of these other guys are out of shape," he pointed out. "Plus they're all carrying their actual wives who aren't the smallest women in the world."

"Maybe they're doing it to have fun, not win money?"

"I'll remind you about the fun when your face is in my sweaty armpit and you're covered in mud, Evie."

"No way, you're not doing anything weird. Double clap for the whole race."

Double clap was our sibling agreement and we'd had it since we were kids. If we clapped our hands against each other twice, then there was no cheating, no betrayals, no lying. We used it where you needed the other one to keep a secret or not mess up a really important school project. You never broke double clap.

"Okay," he conceded, doing the claps. "Just until the race ends."

When the time came, everyone lined up near the starting line and practised picking up their wives. Most people opted for a piggyback or fireman's lift, but one or two did a strange approach of hanging their wife upside down over their back, her legs around his head, which looked surprisingly stable. I did not fancy being dangled upside down, though, so Callum just stuck to the plan.

"Hold onto my arm with this hand," he explained, tapping it. "Grab the belt with the other and push downwards."

"Have you done this before?" I asked as he crouched down.

"Yeah, we do it in rugby training all the time for a strength workout. Ready?"

Now I was having second thoughts. "Um..."

"This was your idea."

"Okay, okay. Just don't drop me."

In a fluid movement, he took hold of me and lifted me upwards, locking his hand into mine to steady me. Surprisingly, I felt very secure, and even when he took a few experimental steps, then jogged for a bit, I wasn't going anywhere. The only issue was that I looked a bit undignified, with his arm between my thighs and my bum on display. I wished I hadn't worn such tight-fitting shorts.

"On your marks... get set..."

I clung onto him as he lined up at the start line, looking down at the ground underneath us.

"Go!"

When he was really running flat out it hurt, crushing my ribs against his shoulders, and it was hard to breathe properly. Luckily, he had to slow down for the obstacles, which gave me a chance to catch my breath, but also meant being flung around as he climbed, slid or descended. My hair was all over the place but I had no way to push it back out of my eyes or mouth, so I just endured it, watching the asphalt beneath us whizzing past. People were cheering and yelling advice, growing in intensity, and I had no idea how long the race was supposed to last. Callum got around another obstacle, tipping me backwards, and then he was running hard, slamming into my ribs again and squashing my tits. I was completely breathless and half-blind with hair when he came to a halt, panting, and gently lowered me to the ground.

"Did we win?" I asked, unclipping the helmet and shoving my hair out of my face.

Callum looked at me, grinning, and held up two fingers in a V.

"Second?"

"Fifty bucks, baby."

Despite the joke nature of the race, I was actually pretty excited. I almost never won anything, especially not anything athletic, and after we'd both been presented with rosettes that said 'SECOND' on them, there was even a podium like the Olympics. The winner was a tall guy, even taller than Callum, and his petite wife, who both gave us friendly smiles and waves as we climbed up onto the podium and the crowd applauded. Callum locked his fingers into mine and held my arm up in celebration when they announced our names (Callum Borgenssen made me snort with laughter), and I squeezed his hand, happy that, somehow, we actually managed to get some kind of sibling bonding out of this.

A guy with a big camera around his neck knelt in front of the podium.

"Big smiles, please."

We smiled and I tilted my head slightly, self-conscious about my hair.

"And husbands, if we can kiss our lovely wives please."

I felt Callum's hand tense, still holding mine, and my heart went into overdrive. The photographer caught his eye and nodded his head in my direction, waiting to take the picture.

Turning to look up at Callum, filled with a mixture of awkwardness and delight at how embarrassing this was for him, I expected him to say something. But he just seemed frozen, looking back at me, suddenly expecting me to take the lead. Awkwardness was replaced with happiness. This was so perfect. The crowd had started a little chant of 'kiss-her, kiss-her, kiss-her' and I'd never seen Callum more mortified in his entire life. I actually laughed a little, and the noise seemed to rouse Callum. His eyes met mine and there was a flash of anger, and he leant down to kiss me.

On the lips. Hard.

My eyes closed and my lips parted automatically, his hand finding my waist, pulling me close. We weren't just kissing, we were snogging, our tongues rubbing together, both of us enthusiastic, neither of us backing down. There was a cheer; someone wolf-whistled; and we broke apart. I felt more breathless than I had after the race, warmth rising from my stomach. I blushed when I realised my nipples were hard.

"Weren't expecting that, were you?" Callum whispered to me, digging his fingers into my waist.

I didn't reply. I had no idea what to say. I couldn't admit to myself that I'd just had the best kiss of my life with my brother.

The crowd for the race dissipated and to say I was conflicted was an understatement. Half of me wanted to run away screaming and excise the memories of the day from my head permanently. The other half of me wanted to drag him into an alley and kiss him again and again and again. The worst part was that I had no idea what his true feelings were: had he just done it to shut me up? Could you kiss someone like that if you didn't really like them? Was it just a joke that meant nothing to him, or even now, as we walked back down the street together, was he thinking about putting his thingy in my...

Okay, absolutely not. There was no way I wanted anything to do with Callum's boy parts. I'd never let a guy do that to me before and I wasn't about to start just because of one good kiss.

"This seems like a decent place," Callum said, rousing me from my thoughts. I followed his gaze, through a plate glass window into a busy diner. "Busy usually means good," he added.

"Um, yeah. Okay."

We got seated at a table near the back and handed menus, but I could barely read it, I was so preoccupied. I was thirsty, though: the warmth of the day and being outside had made my mouth dry. Or was it because of...

"Hello, what can I get you?"

I tried to focus on the menu. "Um, banana milkshake, please."

"Sorry honey, I didn't hear you."

"My girlfriend will have a banana milkshake," Callum said, louder, before giving me a smirk. I felt my face getting hot.

"Oh, you're English, that's awesome. Are you here on vacation?"

"Yeah," Callum said, smiling at the waitress. "We're having a great time."

"That's awesome. Alright, what can I get you?"

"I'll have coffee and, uh, the double bacon burger."

"Coming right up."

I glowered at him and he just shrugged.

"You started it."

"I did not."

"Evie, you definitely did."

I needed to get him back, somehow. He had the upper hand and I did not like it.

My chance came sooner than I'd expected. There was a display of vintage fire engines and tractors and such things and Callum got weirdly interested in them, but I was bored and wanted to shop.

"Can I have my half of the money?" I asked him, tugging his sleeve to get his attention as he gazed at some boring old car.

"What do you mean, 'your half'? It's all mine," he said, not looking around at me.

"What? We both won, we get half each."

"You just got carried around, I did all the hard work. It's my money."

"Don't be a dick, Callum. Just give me half." I tugged harder.

"No, Evie, you're not getting it. I already bought you that milkshake, anyway."

And just like that, I was furious with him again. Ignoring him, I walked off, stormed off really, all the way to the other end of the street where the food trucks were. I never wanted to see his stupid face again. He was always like this: as soon as Mum and Dad weren't around to keep things fair, he always ripped me off and treated me like shit. The kiss had obviously just been another one of his jokes, a way to show me he didn't care at all.

Still steaming, I found a length of brick wall that made up the side of the supermarket and leant against it, waiting. I figured that Callum would eventually need to come here to buy Mum's shopping, but until then he could look at old tractors by himself. The smell of food was making me a bit hungry, but I wasn't going to beg him for money.

To keep my mind off things, I mainly watched the food stall closest to me. It was serving waffles, using a giant bowl of batter and two electric waffle irons, and was staffed entirely by girls about my age. They giggled more than they worked, chorusing "thank you so much!" whenever someone bought a waffle. I worked out that they were raising money for their school or something, but there were more than a few customers attracted by the sight of tight stomachs beneath crop tops and long legs sticking out of athletic shorts.

After a while, I slowly realised that the latest moth drawn to their flame was a familiar older brother. Callum was grinning, watching a blonde girl cooking his waffle, dangling cash in his fingertips above the collecting bin and teasing her. She was laughing, tossing her hair, asking "Oh my God, you're English?", and generally flirting as much as possible with him while he did exactly the same in return. He had the stupidest look on his face and my opportunity was golden.

He was just cracking a joke which had two of the girls on the stall laughing, oh-so-accidentally stretching one arm in the right way to show off his biceps, when I intercepted him, wrapping my arms around him.

"There you are, baby, I was looking for you," I said in my most lovey-dovey voice. "Did you get me a waffle? Oh my God, I love you!" I squeezed him tight and gave the girls on the stall a syrupy look.

They backed right off, smiles sliding down their faces until it was purely business again. I collected the cooked waffle with a smile and took Callum's hand, dragging him away.

"I was going to eat that," he said, watching me take a bite out of it.

"Oh, I'm sorry, you don't want to share with your girlfriend? Or were you more interested in those cute girls than waffles?"

"Clearly it doesn't matter what I was interested in because you were determined to spoil it," he said, snatching the waffle off me. "Thanks so much."

"You're so welcome, baby," I said in a mocking voice, hugging him against his will. "This is the best date ever."

He shoved me away. "Let's just buy the food and get back to the RV."

The next morning was heralded by the sound that everyone dreads on holiday: rain beating down on the roof.

"Doesn't look like it's going anywhere," Dad said, grimacing as he looked out of the rain-streaked windows at the solid clouds. "Probably puts the kibosh on visiting that sculpture trail in the forest today."

Nobody was sorry about that except Dad. Even Mum didn't hide her lack of disappointment.

"Are we just going to drive all day then?" Callum asked, already clearly itching to get back to his games.

"Well, that family I bumped into at the campsite yesterday were full of praise for this giant indoor water park up the road," Mum said cautiously, glancing at me. I gave her a thumbs-up.

"Really? It's not exactly cultural," Dad said, unsure.

"Callum could probably do with the exercise and it's better than being cooped up in here all day," she pointed out.

"I haven't really been keeping up with my exercise routine," Callum added, clearly preferring water slides to doing nothing all day.

Dad sighed. "Well, you're right. It's a good wet day activity."

I clapped my hands. "Great decision, Dad."

"If it has a bar, I'll be happy," he said finally, softening. "We've got a lot of miles to cover before we're done so maybe an easier day would be good for me."

A blessing of being petite and not having gigantic knockers is that I could wear any swimming costumes I liked. I thought about wearing a one-piece which would be better for actually swimming in, but if there was a bar I didn't really want to sit on a lounger in a boring one-piece. Plus Mum would wear one and I didn't want to look like her but younger. So it was a bikini, black with scalloped trim and string ties. Mum would complain it was too revealing but at least it wasn't a thong at the back.

After getting changed at the water park, I bent down to put my belongings in a locker at the bottom of the row. The humidity and smell of chlorinated water permeated everything, and at the last second I remembered to take off my earrings and put them in the locker. When I got up, Callum was standing behind me, hurriedly looking away.

"Never seen a bikini before?" I asked, striking a pose.

"More like I can't believe how bony you are." He shrugged and walked off, leaving me open-mouthed behind him. He was such a dick.

"Okay, we're going to meet back here at three," Dad said, pointing to the giant clock on the wall. "Do not be late."

"Come on," Callum said, pointing to a sign on the wall that said 'Tower Slide of Fear'.

"That looks scary," I pointed out.

"Don't be a baby."

"I'm serious!"

His face softened. "I'll go with you. Show you it's fine."

"No pushing me down it?"

"Promise."

"Or laughing at me?"

"No way. I would never."

I narrowed my eyes. "If you do one thing to piss me off then I'm going straight to Mum."

"I'm on my best behaviour." He held up both his hands. "Double clap?"

I held up my hands too, and we clapped each other's twice. "Double clap," I said, smiling. "Now apologise for calling me bony."

"That was before double clap. I'm not apologising for telling the truth." He smirked and set off towards the slide.

For whatever reason, Callum had decided to actually be nice to me today. He let me go in front of him and he helped me go down all the slides, even the terrifying ones which were pitch dark and sprayed you with icy cold water. There were none of his usual unkind comments about how I swam like I was being electrocuted, or how weirdly short he thought my toes were. He even let a group of seven or eight girls jump in front of us as we were queuing on a staircase for a tall slide, which was basically unheard of because Callum never let anyone take a turn in front of him, not since he was a child. I was about to ask him which alien race he belonged to and why he had abducted my real brother, when I realised that the girls were wearing skimpy bikinis and Callum was at eye level with their backsides.

"Pig," I said, pinching his elbow.

"What?" he asked, affronted.

I gestured towards the girls.

"I'm just being nice." But his grin gave him away.

"Is this why..." The question died on my lips and he looked at me.

"What?"

I was going to ask him 'is this why you've been letting me go in front of you all day', but that would imply that he'd been looking at his sister's arse. And that felt like a weird thing to get him to admit. Not to mention, my arse was okay but it wasn't winning any prizes at the show. But one of the girls in front of us, in a lime green bikini, had a rear so gorgeous it was even making me blush. No wonder she was showing it off.

"Is this why you've got a little problem poking out of your shorts?" I asked, dropping my voice to a whisper.

In a panic, he looked down at his crotch, then when he saw that all was okay down there, he glared at me.

"We did double clap," he said resentfully.

"Okay, sorry. I couldn't resist."

"I get one free shot at you, then, to make it even," he suggested.

"Alright. But you can't save it. You have to use it before we go on this slide."

He looked thoughtful, then an idea occurred to him. "If you wore a bikini like that," he said, glancing at lime green girl, "Someone would call the police because they thought they'd found a skeleton."

"Hilarious."

He was laughing at his own joke. "I think so."

"Back to double clap rules?"

"Right. From now on."

Once we were sick of queueing for slides, we hung out in the wave pool, which was fun because Callum was so much taller than me. When I was being thrown around by the waves, his feet were still firmly on the bottom and it was funny to watch him barely moving a muscle while I fought for my life against the waves and current. Then, having both indulged our childish sides, we decided to explore the swim-up bar.

"You find somewhere to sit," Callum said, mindful of ID requirements.

"Vodka and orange juice, please," I said sweetly, scanning around for a free seating area and also to avoid Mum and Dad. Although if they saw my drink I would just say it was orange juice plain.

"No way they'll think you're passing for 21," he said flatly.

"Oh come on. You won't even try?"

He sighed. "Maybe if you go and wait way over on the other side of the room."

"Alright."

"How are you going to pay me back?" he asked suspiciously.

"I'll find a way. When we get home."

He didn't seem convinced but went to the bar anyway.

I managed to find an enclosed spa pool area that was empty so I claimed it, taking the best seat in the house with a bubble jet right on the perfect spot on my back, no bright overhead lights in my eyes and just the right angle to lean back. The bubbly water washed over me and I felt relaxed, zen and completely serene.

"Couldn't see you anywhere," Callum grumbled when he arrived with drinks. "Thought you'd withered up and died."

"What happened to double clap?"

"That expired when we came into the adult bit of the pool."

I took my drink from him, enjoying the cool touch of the iced drink. Thirstier than I'd thought, I drank the first half in one go, enjoying the kick of the alcohol, and then since, what the hell, it was almost finished, I just saw the rest off as well.

"Steady on, Evie," Callum said, seeing my empty cup. "It's not a race and I'm not getting you another. The bloke behind the bar was suspicious enough the first time."

"I needed refreshment," I said.

"It wasn't that cheap, either."

"Good thing I'm not paying you back, then. Do you know where the parents are?"

Callum nodded. "They're on the far side, talking to some other oldies in one of those hot bath things. They'll never see us from over there."

"Perfect." And with that I stretched out again, closing my eyes, letting the relaxation flood through me. Zen. Serene. The alcohol hit me quite quickly, maybe because of all the exercise, but it was a nice feeling. Like I was floating, which I nearly was in the water. Focus. Zen. Serene.

Callum gave me a two-handed shove out of nowhere and sent me sprawling sideways, sliding along the seat and getting water up my nose.

"What the hell was that for?" I asked, wiping water off my face and coughing.

"You looked way too happy," he said smugly, settling into the exact spot I'd been sitting in. "Oh, and I can tell why. This is a way more comfortable place to sit."

"Callum, fuck off. I was sitting there."

He sat back and closed his eyes just like I had done. "I'll move if you make me."

But he was twice my size. I pushed him and kicked him and tried everything, and there was no budging him. All the while he just lay there, soaking in the water, barely registering my efforts.

"I'll tell Mum," I said finally, my only remaining option.

"She doesn't know who was sitting here first."

"Yeah, but she'll probably believe me anyway."

He opened one eye. "True. But by the time you go all the way over there, I'll have moved and you'll look crazy."

I steamed at him. "Just. Move."

"What's the special word?"

"Please."

"Thank you for asking so politely. The answer is no."

"Oh come on Callum, why are you being like this?"

"Because it's the best seat."

Powerless, I took the nuclear option. I climbed up and onto him and sat myself squarely on top of him, making sure to dig every bony part of my body into him as hard as possible.

"Now try relaxing," I said, satisfied by the grunting and groaning noises he made when I tactically elbowed his ribs.

"Stop hitting me," he complained.

"I'm just trying to get comfortable."

"You really are a brat. You can't get your way so you resort to violence," he said.

I just sat there, leaning back and pretending to relax, squashing his face with my shoulder blade. "Can't hear you. I'm too busy unwinding."

"Brat."

"Can't hear you."

"Brat."

"Can't hear you."

He stopped answering so I just sat there, smug in my victory, waiting for his next move. But he didn't really do anything. I shifted my bodyweight around a bit, trying to provoke him, but nothing. He was giving me the silent treatment, trying to be the bigger person, but I was definitely not falling for it. Wiggling around, I made sure to get him with my heel, elbow and shoulder.

"Fuck," he groaned gently. But it wasn't the kind of groan you let out when someone bruises you with their elbow. It was softer. More... whispery.

I could quickly feel my heartbeat in every part of my body as I had a kind of dawning realisation. The general squishiness that had been under my bum when I'd sat down had turned into something much harder which was pressing into me. And when I moved around, I was rubbing my arse up and down on it inadvertently. Suddenly I was sitting very still and my breathing had sped up.

"Evie..." he said gently, and I felt him put his hands on my waist. I thought he was going to push me off, but he didn't, and we stayed there for another minute or so, the same hard length very obviously still there in his shorts. I tried not to think about the fact that it was his dick. And that I'd probably got him hard like this. He was hard for me. I felt a little rush of arousal of my own. I needed to stop thinking about this. It was just... a biological reaction to someone sitting on his lap. That was all. We were both adults; we could just pretend this hadn't happened.

But that wasn't accounting for my apparently pathological desire to make fun of him.

"This would be fun if I really was your girlfriend, right?" I asked, moving my hips an inch accidentally-on-purpose to see his reaction.

He sounded strained. "Um... yeah." His fingers dug into my waist a little more and I felt his hardness push into me slightly. Also probably accidental. Probably.

I moved my hips again, just as an experiment. No intention behind it. He let out a hard breath.

His left hand dropped to my hip, landing on top of my bikini tie. A few movements of his fingers and it would be undone. The situation suddenly had a new, dangerous edge to it, like we were both trying to see how far the other one would take it. His right hand went upwards, sliding across my skin until he found the lower edge of my bikini, his forefinger touching the scalloping. Another tiny movement and he'd literally be touching my breast. He was so close, daring me to stop him. And my body flushed hot when I realised that I probably wasn't going to. I wanted him to.

Every one of my senses had been completely focused on his hands and the hard part of him pressing into my arse, but whatever still-rational brain cells I had began to raise the alarm. My eyes went back into focus and I watched, helplessly, as I saw Dad coming towards us. He hadn't seen us but it felt like there was half a second of slow motion as I tried to react. And then I did, jumping off Callum like a scalded cat and throwing up a wave of water.

"Oh, there you two are," Dad said, relief in his voice. "I thought you might still be in the wave pool."

"No, we're here," I said, standing as far away from Callum as possible.

"Are you nearly finished? Anything else you still want to do?"

"Um, not really," I said, and Callum shook his head.

"Alright. Shall we go?"

I climbed out of the pool, dripping water, but Callum stayed rigidly immobile.

"You okay, Callum? You look a little bit warm, mate."

"Uh, I just want to spend another minute here. It's really relaxing." He caught my eye and I looked away, trying not to think about the part of his anatomy that had been pressed against me.

"Suit yourself. Come on Evie, your mum is already drying off."

I didn't look back at him. I couldn't trust myself.

Once I'd retrieved my clothes and towel from the locker and wrung the worst of the water out of my hair, I went into a unisex changing cubicle far, far away from the one Mum and Dad were using so I could change. When I tried to lock it behind me, someone suddenly pushed against the door and Callum's face appeared.

"What?" I asked, keeping my voice down.

He put a finger over his lips and stepped into the cubicle, locking it behind him. Callum was still damp from the pool, dripping gently onto the floor. I looked at him, knowing that he wanted to talk and that we couldn't leave it how we had. But I didn't know what to say to him.

And as he stood there, mouth slightly open, looking for the right words, it seemed he didn't know either. There were a few seconds of silence and then the tension snapped.

His body pressed mine up against the partition, his hands on my waist, my hands on his chest, kissing hard. He tasted of booze and I kissed him deeper, more urgently. I felt his hands go down, past my bikini ties until they were on my arse, grabbing, squeezing gently, and I moaned softly into him, pressing myself closer. His cock got hard, rubbing up against my stomach, and I could feel myself getting turned on by it. It felt so... real. So close.

We turned slightly, side-on now, and his hands left my arse and quickly found my tits. My nipples were hard and I pressed my chest forward, the wet material of my bikini top sliding over skin enticingly, suggesting what might happen if he pulled it aside. Our kissing got more urgent, more intense as our tongues rubbed together.

"Callum?"

It was Mum's voice and we sprang apart. She didn't sound that close to the cubicle but just the sound of her voice was enough to have us both panicking.

"Shit," Callum said, grabbing his towel and wrapping it around his waist to hide the obvious erection. A few seconds later he'd let himself out of the cubicle and I sat down on the bench, panting, painfully worked up and horny. I wanted him and he wanted me. He'd been hard for me. Another twenty seconds and clothes might have started coming off, and then...

It didn't feel like a joke any more.

Clearly we couldn't do anything together while Mum and Dad were around, but we both obviously wanted to and the hot secret we were sharing only made everything feel more exciting. We kept catching each others' eyes and smiling, my heart racing.

Once we were back at the RV I could tell I needed another shower to get all the chlorine off my skin, otherwise I was going to dry out. Dad was slightly impatient to get moving but Mum made him see reason, and Callum went off to play his computer games while I went into the tiny bathroom and got myself wet under the shower.

And I meant wet. I scrubbed my skin and hair as quickly as I could, then slipped my hand down between my thighs and found my clit, sighing gently and allowing myself to fully remember what had happened. The hot, intense kisses. His hands on my body. The way I wanted him so much, wanted him to take off my bikini and touch my bare skin. I shivered with excitement at the thought of being naked with him; I'd never really wanted to do that with anyone else before. It was too much exposure. But with Callum, when he was in the mood to be nice to me, I wanted to show him everything, feel him explore me. See his reaction to his sister's nipples for the first time. Know what his face would look like when his fingers pressed into me where I was currently touching, rubbing hard against my clit, my knees bending slightly.

And then... the thought felt almost too naughty to think, but it made me wetter than ever. His cock. He would let me touch it. Caress it and stroke it. Feel it hard and thick in my hand. I blushed when I imagined that he might ask me to suck it. Pleasure him using my mouth. Did he want to look down at his sister's face, our eyes meeting as I wrapped my lips around his shaft? It was so forbidden and yet so nearly reality.

After that? My breath caught and I rubbed my clit hard and fast. Sex. His cock inside me. Fucking me. I'd spread my legs wide and pull him in, my brother's cock so deep in me that I wanted to moan his name, oh Callum, oh fuck, yes, yes-

"Evie, what's taking so long?" Mum yelled through the bathroom door, knocking lightly. "Dad's saying that if we don't get moving soon we might not get to our campsite for the night."

I leant against the wet wall, panting. "Sorry, just getting the conditioner out," I shouted back, trying to catch my breath. "Almost done."

The tension almost became unbearable. With the rain and the travel, we were almost always in the same room as Mum and Dad, and it didn't help that Callum had no intention of keeping his hands to himself.

We were eating breakfast all together as a family, Mum no doubt enjoying the fact that her kids weren't fighting over the food. But the reason for that was because while Callum ate bacon with one hand, the other was sneaking down the back of my shorts, his fingers teasing the waistband of my knickers. I felt almost permanently turned on and I leant forward to get my juice, allowing his fingers to slide a little lower.

"So, everyone," Dad announced, causing Callum to pull his hand away. "We need to be back at the airport by lunchtime tomorrow. If the weather gets better today then we might be able to visit the historic lakeshore."

Mum looked out at the grey skies. "Doesn't seem too likely."

"Otherwise, we can just have a rest and get a head start on packing," Dad said, sitting back in his seat. "Anything you two especially want to do before we leave?"

I glanced at Callum, who was managing to keep a straight face. "Not really," he said, shrugging.

"Okay, well, let's hit the road when we're all cleaned up."

The rain relentlessly fell against the RV's windscreen and it didn't seem likely that we would be doing anything outside today, but I was still glad I'd worn shorts. Callum seemed to take frequent breaks from his usual games to look at my bare legs and I wished there was more I could do to tease him. But Mum was sitting near me, reading a book, and all I could do was pretend to read mine while actually wondering about whether Callum and I would get any time alone today. Tomorrow was obviously no good: the rush of getting ready to fly back to the UK wasn't going to be full of opportunities for fooling around.

I had all but given up when Dad unexpectedly pulled off the road into a parking area.

"There's a scenic viewpoint of the lake here and the rain is easing off a bit. I know it's not much but it beats sitting around," he said, switching off the engine.

Mum put down her book and got up. "You coming, Evie?"

I pretended to examine the weather. "Um, probably not. My hair will get all frizzy."

"We'll only be ten or fifteen minutes," Dad said, stretching. "But so long as it keeps your precious hair in shape..."

I rolled my eyes but didn't deign to answer.

The second Mum and Dad were out of sight, I went over to Callum. His headset was still on and he was squinting hard at his handheld game thing, pressing buttons rapidly.

"Um, hello?" I asked, waving my hand in front of his face.

"What?" he asked, pausing the game and taking his headset off.

"Mum and Dad have gone out for ten minutes."

His expression changed instantly from mild irritation to desire, and his eyes flicked down over my t-shirt and shorts. "Good," he said, tossing the game machine away and reaching out for me, making me squeal as he dragged me onto his lap, straddling him.

"Mm, hi," I murmured as he kissed my neck, tilting my head back. His hands were firmly on my arse again and I pushed my hips down onto him, rubbing firmly on his jeans until with satisfaction I felt his dick get hard beneath me.

He kissed my neck and jaw and then we kissed properly, our lips meeting, and I couldn't believe just how good it felt to kiss him. It seemed to put my entire body in tune with what I wanted. Pressing down, I found a nice rhythm that provided pressure against my clit and I moaned softly. Callum's hands squeezed my arse again, pulling me in closer.

"Do you think we've got time to...?" I asked in a low voice, my pulse racing as I thought about the possibility that this might be it.

Callum kissed me again firmly. "In ten minutes? I doubt it. What if Mum and Dad came back and we were..."

That image didn't need any further elaboration.

"But we might not get another chance," I pointed out.

"Maybe that's for the best," he pointed out, and he was right. As much as I wanted him right now, would I regret it in the long run?

"Okay," I said, trying to hide my disappointment. I stopped moving my hips and sat up a little.

"Hey, Evie," Callum said, looking at me. "We've still got ten minutes. I didn't want to stop."

I giggled. "Okay. Fine by me."

I'm not sure what it was specifically but I just loved his hands on me. Not just on my arse or my waist, pulling me down onto his hardness, but when he slid them upwards, under my shirt, his fingers gripping my waist and finding the back of my bra strap... I never wanted him to stop.

His fingers flexed and undid the clasp and I felt the material of my bra relax. I couldn't easily take it off without taking my shirt off first, and I was wondering whether this was a good idea when his hands moved firmly onto my stomach, then upwards, going underneath my bra as he kissed me deeply.

My head was whirling. Callum was touching my boobs. His fingers were on my nipples, squeezing and rubbing and fuck, this felt really good. Everything was constricted under my shirt and that enhanced it, keeping his touch firm. He opened his hands and squeezed gently and I moaned into him, flashes of pleasure shooting through me. I rubbed myself on him harder, feeling him push back. And then he let go, withdrawing his hands and leaving me frustrated and needy.

"Fuck," I whispered, disappointed as he put one hand on the small of my back. I thought we were going to stop, but in a rush he used his other hand to drag my shirt and bra upwards, exposing my tits, and his head darted downwards.

"Fuck!" This time it wasn't disappointment, it was arousal as I felt his mouth on my nipple. My brother was actually sucking my tits right now and I was soaking wet as a result. He swapped to the other one, both of my nipples hard, the tip of his tongue teasing them.

Then, inevitably, he suddenly yanked my shirt and bra back down and lifted me off him.

"Mum," he hissed, but even before he said it I'd heard her voice outside, and a second later she was climbing the steps into the RV.

"What are you two doing?" she asked, curious about why we were sitting together as she brushed fine raindrops off her face.

"Callum wanted to show me something on his game," I lied, standing up, very aware that my bra wasn't fastened.

"Oh," Mum said, sounding happy. "Okay. I'm pleased you two are having fun."

The moment she looked away I reached up my back and hurriedly did up the strap. Callum eyed me with a smirk and I made a face at him. It felt like we were never going to get a chance where we weren't interrupted, but as he said, maybe it was for the best.

My boobs tingled with sensitivity and arousal for the rest of the day. They never felt this good when I touched them myself. Somehow Callum seemed unaffected: he definitely kept looking at any bit of my exposed skin he could see, but while I felt constantly on edge, he seemed relaxed.

Midway through the afternoon the temperature in the RV unexpectedly climbed a couple of degrees and I realised that the sun had come out. Everything outside was still wet from the rain but the clouds were clearing, and Dad had a big smile on his face as he turned off the main road in the direction of 'Historic Lakeshore'.

"You two really don't want to come?" Dad asked, sounding incredulous.

Callum shrugged. "I might have a nap. I've seen enough historic wooden buildings in this country to last a lifetime."

Dad turned to me and I tried to think of something plausible. "I'm up to a really good bit of my book, and if I don't read it now, I'll want to read it tomorrow when I should be packing."

"Come on, Brian, let's leave the kids. They're not bothered and it'll be nice just the two of us," Mum said, snaking her arm up Dad's back. "We can get an ice cream."

That prospect seemed to sway Dad. "Alright then. We'll be back by dinner time."

"Okay, have fun," I said, giving them a little wave.

Then they were gone. I looked over at Callum. He was already looking at me. I felt rising nerves as I got up and walked towards him. He got up too, and I hesitated, thinking that we might carry on where we'd left off.

In two steps he closed the gap between us, kissing my neck just below my ear and putting his hands on my thighs. I put mine around his neck, which felt most natural, and then he tensed, scooping me up and pushing me against the bathroom door.

"Callum," I said, alarmed, wrapping my legs around his waist, but he never slowed down. He seemed to support my weight easily, one hand under my bum, my back flat to the door, which left one hand free. Slowly but urgently he pushed my shirt up, over my bra and then over my head, then without pausing he undid my bra again and pulled it off. Being topless in front of him was a thrill, and I gasped when his fingers began teasing my nipples again. But he was overwhelming me with kisses now, more aggressive than ever, the soft wetness of his mouth contrasting with the hardness everywhere else.

With my legs around his waist, I could feel the length of his cock pressing firmly into my pussy through our clothes. Every other time that we'd pressed together like this it had felt like a question: what would happen if there was nothing between us, just skin touching skin? But now the question was being answered. We were going to do it. In a few minutes I would know what it was like to have sex with a guy. With my brother. And just the anticipation was turning me on more than ever.

Gently, Callum lowered me to the floor, letting me put my weight back on my feet as he undid my shorts and pushed them down. I kicked them into a pile with my shirt and bra, then in another frenzy of kissing and touching I pulled off his shirt, undid his belt and pushed down his jeans. I ran my hands all over his arms and his chest, feeling his athletic muscles and also the softness of his skin. It was the same with everything about him: soft and hard together. His cock was pointing straight up in his boxers but when it came to it, I was too afraid to touch it. Using my body seemed natural, but using my hand... Strangely, it made me nervous.

But it quickly didn't matter. Callum kissed me again, more softly, holding me for a moment, then curled his fingers around the waistband of my knickers and tugged them down, letting them fall from my knees to my ankles. I flicked them away, naked and ready. It was really going to happen.

Callum scooped me up again, carrying me, reminding me suddenly of the race and how incredibly different our relationship had felt then. But maybe there had been something there. An underlying tension beneath the sibling teasing. I couldn't give it any more thought: he threw me down on Mum and Dad's bed, on my back, and I looked up at him. My legs were spread, my nipples standing up hard on my chest, my mouth open, panting. He drank me in, smiling, stepping closer, pausing for a moment to pull down the blinds next to the bed.

This was where we passed into unfamiliar territory for me. Fucking your brother was probably unfamiliar for most people, admittedly, but I hadn't fucked anyone else and wasn't exactly sure what to do. I'd seen porn, obviously, but somehow blowjob-missionary-cowgirl-doggy-facial didn't seem to be how this was going to work for us. Would he put it straight in? Did we need some kind of foreplay?

Unexpectedly, though, Callum took one more look at me before climbing onto the bed between my thighs, putting his hands under my bum, my legs up on his shoulders and...

Oh fuck. He was eating my pussy. And it felt really, really good. Amazing. I moaned out loud as his tongue pushed up against my clit, flicking over it, stimulating me exactly where I'd wanted to be stimulated for hours. Days. Ever since that first kiss, in the warm sun on the podium. I hadn't realised how good someone else's mouth on my clit would feel. And he was only just getting started.

His eyes found mine, looking upwards, moving gently up and down with his tongue. Callum was hot. And he was my brother, which made this even more intoxicatingly good. It felt wrong but so fucking right. I moaned again, my thighs spreading wider, giving him closer access to my wetness and he took advantage. Long, slow licks all over my pussy drove me wild, teasing me, making me desperate for more. And then he'd focus on my clit again, sucking, rubbing, anything to get me to writhe on the bed and dig my heels into his back.

My hands felt useless: I didn't need to guide him. So instead I grabbed my boobs, partly holding them to stop them moving on my chest as my hips pushed into him, but partly squeezing and pinching my nipples to heighten the pleasure. I'd never been so rough with them before but Callum was taking me to another level, my body sparking all over with pleasure.

"Callum, I... keep going," I begged, my voice sounding strangely hoarse. I needed him to keep licking my clit. I knew I couldn't cope if he stopped. But he didn't stop; he gripped my thighs and licked hard, flicking back and forth over and over until finally I reached the peak and everything went off at once.

It was like being weightless, because I didn't need to control my body any more. My muscles took over on their own, tensing against him as I came on his tongue. I just lay back and felt the sensation wash over me, the shaking enhancing it, until I came down the other side and finally let out my breath in a huge moan of satisfaction.

"Fuck, Evie," Callum said as I nudged him away, too sensitive to continue. His mouth was wet and I knew it was from me, but I didn't care and I used my legs to push him up the bed until he was lying on top of me. We kissed, his tongue especially tasting of pussy, but it tasted so fucking good. I never wanted to stop kissing him. I loved his weight on top of me, his arms around me, the enticing prospect of his hard cock up against my stomach again.

"Callum?" I asked, breathless.

"Yeah?"

"Will you fuck me now?"

There was a moment's hesitation in his expression as he looked at me. "Are you on birth control?"

I nodded. "Yeah, I'm on the pill."

"Okay. Great." He smiled, the hesitation gone.

I helped him take his boxers off as much as I could, then let him throw them off the bed. He adjusted how he was lying, raising his hips, and I gasped when I felt a smooth, hard tip bump up against me.

"Relax," he said gently, kissing me again as my legs tensed up either side of him. I tried to do as he said, not overthinking it. I didn't want it to hurt, but-

Another bump, and he reached down to guide it. I braced myself.

"Evie. Relax," he repeated, brushing his lips against my forehead.

I nodded wordlessly. Deep breath. It wouldn't be bad. It might hurt for a second but it would be like an injection. Over before I knew it. Probably. It was supposed to feel good, eventually. But what if-

The head of his cock pushed into me. He paused, then pushed again, more of it going inside. The pain never came. Only unbelievable pleasure. Holy fuck: no wonder the girls at uni were practically obsessed with dick. If this was what being fucked felt like... yes please.

He stopped moving when he was all the way inside. Being full of him was the best feeling in the world, and I kissed him quickly.

"You okay?" he asked, staying still.

"So fucking okay. Really good."

"Should I...?"

I giggled, which felt slightly strange with a cock inside me. "Please fuck me, big brother."

As well as eating pussy well, he fucked well. Slow, smooth, easy thrusts in and out, holding his weight on his arms, alternating between filling me and making me moan, and pulling back, making me want more. He gained speed, turning me on even more, reaching a point where he was really fucking me and our bodies were slapping together. My moans were so frequent it was almost like one long noise, and his grunts were clearly getting louder and more excited.

"Evie, I..."

"What?"

"I'm close. I'm going to cum."

Oh fuck. This was it. A guy shooting inside me for the first time. My pussy making him cum.

"Okay," I said, readying myself.

"Ask for it," he said, moving fast and hard.

It took me half a second to understand what he meant. "Oh, yeah, uh, can you cum?"

He managed a smile. "Ask nicely, I meant."

I took a second to collect myself. This needed me to be my sexiest self. Dig deep to find the dirty part of me.

"Will you please cum in your little sister's virgin pussy?"

His sudden moan, rapid movements and the feeling of his cock pulsing over and over told me that I'd done the right thing. His cock pushed deep at last, as deep as he could, his breathing rapid, and then he relaxed. I kissed him and he kissed me back, gentler now, a warm glow building from my core.

"I didn't realise you were... that you hadn't done this before," he finally said, looking into my eyes.

"It's okay. I really liked it," I told him.

"Fuck... it's kinda hot, Evie. I just took my sister's virginity."

He broke into a big smile and I smiled back.

Callum was anxious that we didn't get cum all over the sheets on Mum and Dad's bed so he used his boxers at first, planning to just ball them up and wash them when we got back home, then he found some wipes. Cleaned up, he climbed back into bed next to me and put his arms around me, letting me rest my head on his chest. It all just felt so perfect. I couldn't have asked for a better way to have my first time. More than anything, I felt oddly peaceful. Like it was just he and I, the only two people in the world.

"Evie?" he asked in a gentle voice which I heard partly through his chest.

"Hmm?"

"I think we should make this a holiday-only thing."

I nodded. I knew there was no way this could work long-term, especially as once we got back to the UK I had to go back to uni and he had a job to start. "I think you're right." I was easier to see now I wasn't desperate to fuck him every single moment.

"Is that okay?"

"Yeah."

We left it at that.

"Why do I have to repeat myself a million times? You are all responsible for your own passports. Callum has his; why haven't you got yours?"

Mum was really exasperated as I dug frantically through my bag. "I definitely packed it, I remember!" I protested. "It's here somewhere."

"Well somewhere isn't really cutting it, darling. People are waiting."

"I know, Mum, I can see that."

She pursed her lips to stop herself saying any more. I just couldn't think where I had put the passport, and having Dad and Callum hanging around by the check-in counter, muttering to each other wasn't helping.

"Yes!" I yelled, far too loud, when I triumphantly found it in a little-used side pocket. Mum snatched it out of my hand and marched off to give it to Dad, while I desperately stuffed everything back into my bag.

"Nice work embarrassing us," Callum said, elbowing me as we walked over to the security lines.

"You're the embarrassment," I countered, but I didn't have a good comeback and it showed. Callum just laughed, so I lashed out and kicked the wheel of his suitcase, sending it off balance so it spun out of control. As he righted it, I sped past, getting into the queue before him.

"Mum, Evie kicked my suitcase."

"Callum called me an embarrassment."

"Shut up both of you."

Once we were through security and had found our gate, it was still half an hour until boarding so I offered to get everyone coffee, assuming they paid me back. There was a chain cafe about two minutes' walk away and Callum offered to come with me to help carry.

"And anyway, you still owe me for that drink at the water park, so you can buy my coffee," he pointed out as we walked.

"Fine. Just order something normal and not a ten quid triple mocchiato monstrosity."

"I'll order whatever I want, thanks."

I knew he'd pick something ridiculous. I just knew it. Mum and Dad both just wanted Americanos, but I knew Callum wouldn't miss his chance.

"Get me a... strawberry mango iced tea, caramel shot, hazelnut shot, double shot of espresso."

"No Callum, that's disgusting. I'm not doing that."

"You owe me, Evie. I'm not ordering anything else."

"Well I'm not ordering that," I said, firmly.

"I'll tell Mum about you owing me for a drink and not paying me back."

"Fine. Just... fuck off. Fine."

The woman at the counter barely managed a smile as I approached.

"Three regular Americanos, please."

"Okay."

"And my boyfriend," I said, loud enough for Callum to hear, "Says he wants a strawberry and mango iced tea, shot of hazelnut, shot of caramel, double shot of espresso."

The server looked at Callum. "You sure?"

"Definitely."

"Okay. What's your name?"

"Evie."

"Ivy?"

"Yeah."

As Callum and I collected the drinks, he deliberately trod on my foot.

"Boyfriend?" he hissed. "Not that again."

I grinned. "Tough shit, boyfriend. I can say what I want."

"Be careful what you wish for, Evie," he said, using his free hand to swat me on the bum as we walked.

"Callum!"

"What? Nobody knows us here."

"But still."

"Not my fault your bum looks amazing in those leggings. If you really were my girlfriend I'd be doing a lot more than just smacking that arse."

I could feel myself blushing. "Seriously, Callum. I thought we said-"

"The holiday isn't over until we get home," he said, dropping his voice.

I laughed nervously. "True..."

"There's a family bathroom near the coffee place. Meet me there in three minutes."

Before I could reply, we got back to where Mum and Dad were sitting and handed them their drinks.

"Just going to run to the bathroom," Callum said, not catching my eye.

"Alright," Dad said, checking his watch.

I let a couple of minutes pass, fiddling anxiously with the tag on my bag. "I think I need to go, too."

Dad sighed. "It's fifteen minutes until boarding opens. Don't take ages."

I dashed off, retracing my steps until I spotted the family bathroom Callum had mentioned. Going up to the door, I knocked gently.

He opened it and I stepped inside, really hoping nobody had been watching.

"There's no cameras or anything? I don't want to get arrested," I said, still feeling nervous as the door closed behind me..

"Not that I can see," Callum said, putting his hand on my waist and kissing me. I kissed him back, putting my arms around him, and then yelped a little when he slapped my bum again. But then his hands slid confidently down my back and into my leggings, under my knickers. I moaned gently, kissing him harder.

"We don't have long," I pointed out after the kiss.

"True." We both looked around, but there were no surfaces to sit on, and I wasn't sure I was capable of standing-up sex in under ten minutes. Particularly because Callum was so much taller than me.

"What do you think?" I asked, unsure.

"I... don't know," he admitted.

"If I was your girlfriend, what would you want me to do?" I asked, giggling slightly as I kissed him again.

He looked a bit embarrassed. "Would you... wank me off?"

I smiled and nodded. "Okay."

He undid his jeans and pulled out his cock, which was already hard. In the harsh lighting of the bathroom this was the first time I'd really seen it, and I realised that this was the cock that had been inside me. I'd been fucked with it. My brother's cock. It was... essentially like every other cock I'd ever seen, which were only in videos. Hard. Throbbing. Slightly damp at the end.

I wrapped my fingers around it and began to rub. Callum groaned so I kept going. It was surprisingly intuitive; hand around the shaft, go up and down. I tried varying the speed and intensity until I found something that wasn't going to give me cramps, and then I focused on kissing him, continuing to stroke it.

"Fuck..." Callum breathed.

"Is this okay?"

"Yes. It really is."

I carried on, kissing him, stroking him, waiting for him to give me my next cue.

"Evie? Um... it's okay if you don't want to, but... would you suck it? Just for a bit?"

I nodded again. I had wondered if we might be going in this direction. But I was okay with it. Excited, even. My first blowjob.

Dropping onto my knees on the hard tiles, I just dived straight in, putting it in my mouth before I could overthink it. His cock tasted really strongly of him and was more rubbery than I expected, and I licked slowly, getting it nice and wet so it was easier to rub my lips over. It was quite hard to fit it into my mouth without accidentally biting him, and I was just thinking about how to relax my jaw when he groaned.

"I'm going to cum, Evie."

It caught me by surprise, but I knew I couldn't let his cum get on my clothes at all, and I didn't have tissues ready to catch it. Maybe he'd planned it this way, but there was no real alternative to just keeping my lips tight round it and swallowing as his cum flooded my mouth, his cock flexing as it did.

The taste was... extremely intense. As soon as I was sure I'd swallowed it all, I coughed, my eyes watering a bit, and I stood up.

"I need coffee," I told him with a laugh as he looked at me, concerned. But when we got back to Mum and Dad and I had a few weird tasting mouthfuls of cum-coffee, I felt good. I wasn't a virgin. And I'd sucked a guy off and swallowed it. I felt sexy and naughty and experienced. But, I realised with mounting horror, I felt really fucking horny. And I was about to get on an eight hour flight with my parents.

"Technically it's my armrest," Callum said in a know-it-all voice.

"No, because I have the window seat, so the armrest on the right is mine," I said, getting annoyed as he kept his arm rigidly in place, covering the entire armrest and not moving an inch even when I pinched him.

"Mum, Evie's trying to hurt me."

"You two, stop it," Mum said wearily, not bothering to remove her eye mask. "If you don't sleep you'll be exhausted when we land."

"How am I supposed to sleep without an armrest?" I asked, digging my nail into Callum's hand.

"Mum, Evie's trying to hurt me again."

Now Mum flipped her eye mask up. "That's enough," she said sharply, giving both of us the evil eye. "Evie, you're almost nineteen. Callum, you're twenty-one. You're both adults and far too old for this petty bickering. Put that armrest up: nobody is having it."

"But it's my armrest," Callum complained, so Mum just reached across him and pushed the armrest up and out of the way.

"Sleep, now. If I hear another word from either of you, the consequences will be severe."

She put her eye mask back on and pointedly ignored us.

"Well done, idiot," I hissed at Callum, too quiet for Mum to hear over the drone of the engines. I grabbed my blanket and tried to get comfortable underneath it.

"It's alright for you, you're tiny. I barely fit in the seat," Callum said. He was right: the best sleeping position he could fit in was sitting and trying to lie back. I was small enough that I could almost lie fully on my side, or tuck my legs up underneath myself.

"Too bad, so sad," I taunted him, keeping my voice down, but when he stretched his legs out into an area of legroom I wasn't using, I didn't complain. He shuffled and fidgeted for a minute, then began breathing evenly, and to my annoyance he had fallen asleep. That was another parental gene: Dad and I could barely sleep in a feather bed with silk sheets, while Mum and Callum could be sound asleep in the middle of a warehouse rave.

I kept my eyes closed, trying to think sleepy thoughts, but my brain, no doubt saturated in sex hormones, kept returning to what we'd done in the bathroom. Right this second, I had Callum's cum in my stomach. It had come out of my brother's balls and I'd swallowed it straight from his cock. I'd made him cum with my mouth.

Now I was getting wet. I tried to think about something else, something boring, but I just wasn't tired. Callum had cum inside me twice now. My mouth and my pussy. It had been the best thing ever and I had no idea how I was going to survive without it. Did he feel the same way? Did he see me and think 'there's my sister, she's had my cum inside her, I can't wait to do it again'? Fuck, I really wanted it. And trying to sleep was only making me more horny, not less.

Callum shifted in his sleep, his arm bumping into my thigh on the seat. I lifted my blanket and put it over his hand. He didn't react, but my pussy was definitely in need of attention and his hand was about six inches away.

"Callum?" I asked, nudging him.

"Huh?"

"Are you awake?"

"I am now," he said, not opening his eyes.

I leant in close to his ear. "I'm really worked up," I said, as seductively as possible, putting my hand on his.

Now his eyes opened. "Really?"

He was too loud so I shushed him. "I need help."

When he turned his head to look at me, he was smirking. "Mile high club?"

"Ew, no, the bathrooms are disgusting on this plane."

"You don't have to use a bathroom."

"How do you suggest we do it with Mum right there, then?"

"Good point. I'm going back to sleep."

Frustrated, I squeezed his hand. "I don't mind that she's there... we just need to be quiet."

He gave me one of those knowing smiles that I hated so much. "Wow, Evie, you've really changed. I thought you were the perfect daughter?"

"That was before you fucked me," I whispered, and he let out a low gasp. Carefully, I lifted his hand and put it on my thigh properly. "Everything is under the blanket," I said, softly and encouragingly. "I'll try not to make any noise."

He didn't hesitate, moving his hand confidently onto my pussy through my clothes. I gasped, then bit my lip. Now I was being too loud.

His fingers began to move, finding my clit and rubbing firmly, and I closed my eyes, focusing completely on making no noise whatsoever. But the more he continued, the more the seam of my knickers began to annoy me until I couldn't take it.

"One second," I told him, lifting his hand away. Without dislodging the blanket, I lifted my hips up and pushed my leggings and knickers down to my knees. I didn't love the feeling of aeroplane seat on my bare arse but I didn't have a lot of choice.

Once I was done, he went back to rubbing my clit and fuck, this felt a lot better. His fingers quickly got wet from me and moved easily over me, the sensations running through me quickly growing in intensity. Not moaning or making any noise was getting more and more difficult, but Callum wasn't slowing down or stopping. I began to realise that, unless I stopped him, he was going to make me cum, and I didn't think there was any way I would be able to do that silently. But I also wasn't going to make him stop.

The solution was for me to bury my face in his shoulder with an extra layer of blanket between us. Then my breathless noises were muffled enough that they were lost in the background noise of the aircraft, and I could focus entirely on what he was going to my clit. Which felt so, so good. I was so wet and desperate and I just needed him to keep going and going until I could finally get some release. And he did, moving his arm to a slightly different angle so he could keep up the pressure on my clit, his fingers moving rapidly back and forth while I took desperate occasional breaths outside the blanket muffler, like a swimmer surfacing for air.

"Yes, yes," I murmured, wondering if I was straying into the territory of being too loud, but not really caring as my body went rigid and his fingers pushed me over the edge. I went very light-headed and saw dancing patterns in front of my eyes as I orgasmed, and it felt like the seat was spinning with me in it. Maybe a consequence of the altitude or something, or maybe Callum just had the power to make me feel that good with his fingers alone. Either way, I panted and dug my fingers into him as I came down, feeling so much better than I had ten minutes ago.

Once my knickers and leggings were back on, I slipped my hand down onto his crotch to squeeze his hard cock through his trousers, wondering if we could get away with more. But a steward came past, dealing with a call from someone in the row in front, making me hurriedly pull my hands away. By the time we were back to being unobserved, I could tell Callum had fallen asleep again, and this time I supposed it wasn't worth waking him. In any case, I was a lot more concerned about being caught by someone now I wasn't sitting in a haze of sexual desire.

There was a certain bittersweetness to arriving back in London. It did feel really good to be back to familiarity, with cars on the correct side of the road and English accents everywhere. But on the other hand, as I watched Callum dragging his suitcase off the moving belt, I realised that, per our agreement, our physical relationship was over. It somehow felt too early to review it, to decide how I would remember it. I needed some space and some distance, first. And in any case, I'd only managed a couple of hours' sleep on the plane and I was too tired to think about anything in depth.

Since I was so jet-lagged, I did manage to curl up in the back of the car once we'd set off driving, snuggled under my blanket, and got another ninety minutes or so. With four suitcases to shift, we'd driven to the airport, but Dad was clearly now regretting needing to drive back. The dark circles beneath his eyes and his grey skin tone suggested he hadn't slept much more than I had.

It had just started to get dark when Dad pulled off the motorway, murmuring something to Mum that I couldn't hear. It was too early to be getting home so I sat up and paid attention, wondering if we were stopping for something to eat.

"Sorry, kids, I'm too knackered to drive all the way back," Dad said once we were parked, turning in his seat to face us. "I can never sleep on planes. Any volunteers to drive the rest of the way?" he asked, not sounding hopeful.

"I haven't passed my test yet so I can't go on the motorway," I pointed out.

"And I'm not insured, remember?" Callum added.

He looked at Mum.

"I'm tired too," she said. "Let's just book a couple of rooms at a hotel and we'll carry on in the morning."

Ten minutes of parental fussing over a tiny phone screen later, Mum looked cautiously at the two of us. "All they have available for you two is a family room with one double bed and one single. Please don't argue over who gets which bed - it's better than no bed at all."

It felt like years since I'd slept lying down so I would have taken the single bed very happily, but Callum spoke first. "Evie can have the double," he said, shrugging. "I don't mind. I slept a bit already."

We ate dinner all together but Dad and I were clearly flagging, so we skipped dessert and went upstairs to our rooms; Callum and I were on the third floor, Mum and Dad on the fourth. I felt a little thrill, after weeks of living in an RV, when I unlocked the door to an actual hotel room and surveyed the proper beds and full-size bathroom.

Callum chucked his stuff on the single bed while I rolled my suitcase up to the double, looking at the big pillows and fresh sheets with excitement. The only thing I needed before a nice long sleep was a shower, and I turned to ask Callum whether he wanted to go first.

He was looking at me with an unreadable expression, and I instantly wondered whether he was regretting the choice of bed. There was no way I was going to let him take it off me. I needed this.

"Thanks for taking the single," I said, smiling, tactically reminding him of what he'd told Mum.

"I'm not sleeping in it," he said, reaching down to his waist and pulling his t-shirt over his head. I was annoyed that he was going to make us swap beds the moment Mum and Dad were gone, which was such a petty move. But he was also really fucking hot without his shirt on. I was paralysed with indecision.

Callum strode over and kissed me, putting his hands on my waist and holding me tightly. I kissed him back, smiling, so happy this was still happening.

"What about our agreement?" I asked in a whisper after the kiss, meeting his eyes.

"Fuck that. We've got a whole night together. We can do anything we want."

That sounded like everything I had ever wanted.

Neither of us made it as far as the shower. After undressing each other, his fingers worked their magic on my clit until I was wet and clinging to him, and then he threw me down onto the bed, my arms and legs flailing to keep my balance.

"On all fours," he said, slapping my bum as I tried to get up, giggling. I did as I was told, excited to try a new position for the first time. He was too tall to kneel on the bed behind me, so he stood on the floor, my legs either side of him, and I let out an unrestrained moan of pleasure when he slid his cock into me. This felt so much more intense than lying on my back, and his cock seemed somehow to be even deeper.

"Oh, yes, yes," I said as he started to fuck me, my tits bouncing with the impact each time he pushed deep into me. I could feel his hands on my hips, gripping me and pulling me into him, but I wanted more. I backed up onto him, pushing my hips back as he pushed forwards, and I heard him moan. Clearly this was working for both of us.

"Evie, fuck," he said, slowing down his movements, but I kept going, flexing my thighs so I could bury him inside me over and over, my moans coming faster than I could keep up with. "I'm... you're going to make me cum."

I just laughed happily. "I want it."

"You want your brother to cum in your pussy?"

"Yes, fuck yes, cum in your sister. I need it."

He grunted and held me tight, thrusting in again hard and fast, so relentless that it was all I could do to keep my hips in place as he came inside me, hardly slowing down at all. Then he pushed deep and held his cock there, filling me entirely. So far he hadn't lasted very long when we were together, but I took it as a compliment. Clearly having sex with me turned him on so much that he couldn't control himself.

With a noise of soft satisfaction, he finally pulled back, and I stayed in place for a second, my eyes squeezed closed, missing the feeling of his cock. Then I pushed my thighs together and felt a drip of hot cum slide out of me, and something about that sensation was so overwhelming that I fell forwards, lying on my front, not caring one tiny bit about the state of the sheets.

"You look fucking hot, Evie," Connor said, running his hand over my leg.

"I can't believe we... again," I said, giggling and turning to look at him over my shoulder.

"I know. Listen, I'm just going to have a quick shower. Don't go anywhere."

I looked at the four walls of the hotel room theatrically. "Where would I go?"

But in the end, I did ignore what he said. He was taking too long in the shower and I was still feeling fucking horny. I wanted him. So I got up and went to find him, pushing open the unlocked bathroom door.

"Evie?" Callum asked, surprised.

"I'm having a shower too," I told him, sliding open the door to the shower cubicle and getting blasted with warm steam.

"Great idea," he grinned, rinsing off soap, his cock hanging soft between his legs. I needed to change that, so I cupped his wet balls with one hand while kissing his muscular chest.

"Round two?" I suggested, looking up at him through my eyelashes.

"It's only been five minutes or something, give me a chance."

"What if it was for your sexy little sister?" I asked, moving my hand from his balls to stroke his shaft, feeling him pulse with sudden arousal.

It didn't take him long to get hard again. For me.

THE END
