Hot Tubs are Dangerous!

Sidenote: I wrote this story over a few hours and I wouldn't write off the possibility of a sequel. This is my first story and also first time writing anything close to erotica, so please let me know what you think. I think I got a little carried away so it is somewhat long with big build-up!

------------------------------------

I've never really had a thing for my sister, she's younger than me by 2 years so we were always close in age, but never close at all in a family perspective.

We each lead our own lives completely separate to each other, and I never found her attractive, or even worth looking at. until a few months ago my friends told me "Hey you know, your sister is quite fit you know," and of course it being my sister I was just like-

"Yeah, sure whatever, I don't care." After that I tried to really look, but still couldn't see it.

My sister is fairly slim, nothing like a swimmer's body, but by no means chubby. I would say she is the average height for a girl, maybe 5 ft 6 with long flowing hair. Her chest however was quite unremarkable to most, fairly small, so growing up I never really noticed much change. Her name is Chloe by the way.

Anyway, I guess we go back to the story at hand, or at least how it all started:

A few months ago, my parents decided to invest in a hot tub, we recently had all our backyard renovated and it looked great and spacious. I have no idea what brought on this sudden need to have a hot tub in the backyard, but I can't say I was complaining. For the first month I was too busy with work to even bother with it, I mean the thing took like 3 hours to heat up to a nice hot temperature, and what's the point in lukewarm bubble water, right?

The second month I figured fuck it lets give it a go, our fences to the neighbours are not so big, they're also parted wooden slabs, so you can see through them if you try hard enough. So pretty much walking around the backyard completely nude was a completely off the table. leaving me no choice but to wear swim shorts.

And thus, our tale truly begins...

"Hey Chloe, how long has the hot tub been on?"

"Only about 2 Hours, so it won't really be hot, why? don't tell me you're finally going in?" Chloe said taking a jab at the fact I hadn't yet, which was pretty strange considering it was rare she went in either.

"Yeah sure, why not, not like I have anything better to do right now."

"Yeah well, just don't be doing anything funny in there," Chloe joked, she liked to tease every now and then, but I rarely ever rose to it.

"Oh behave, I just feel like relaxing, I mean it's pretty hot today." Although secretly thinking it's not like anyone would even know if I did.

I went outside and got in the tub, she was right, it was sort of warm but nothing really compared to a hot shower... I put my headphones on and music and just kinda zoned out for a bit, until freezing cold water lands on my head!

"What the fuck!" I shout and look up; there I see Chloe with a bucket laughing

"Glad you finally got in, I've been waiting to do that," she closed the window and I got up and ran upstairs still soaking wet, this was my first mistake... It had been a few years since id had to wear swim shorts anywhere, so I had completely forgotten the issue with these specific white shorts.

I banged on the bathroom door, which was locked.

"Chloe open the fucking door, that wasn't funny I was completely relaxed and zoned out."

All I could hear was laughter on the other side of the door, 2 years my junior she was clearly still a child at heart.

"Oh, come on Bro it was just a joke lighten up, you know you would've done it to me if you would have realised."

"Oh, really huh." Then it hit me, she was in the bathroom, the one place inside the house I could get wet, and I wanted my revenge. I went downstairs and filled up my own little tub of water, nothing as big as a bucket, but something that she would definitely feel the cold from. It only took me a minute or 2 to get it all set up, and as soon as the bathroom door opened, BAM water all over her, and boy did she scream. Unbeknownst to me, she had just taken a shower before she threw water on me and was wearing just a towel. Well with all the water I threw the towel got soaked and fell down... As soon as I realised this, I couldn't help but to stare before the realisation struck her that hew towel had fallen form her chest!

Up until this point, I had been with a few girls in my life, and I had realised that I liked smaller boobs, not like a flat chest, but a nice A/B cup. which coincidentally I just learned my sister was. She realised about 5 seconds later that her towel was now only around her waist and not covering the rest of her and immediately turned around and fixed the towel.

"You twat, what the fuck!"

"Well revenge is a dish best served cold." I said smirking at my quick-thinking pun.

"Get me another towel NOW!" She screamed

"No chance! You threw a whole bucket of water at me in the hot tub, this was merely my revenge." I smirked some more knowing full well she couldn't really argue with that... However, my sister decided to play a different angle.

"So, what you're saying is you knew I was about to come out of the bathroom with nothing but a towel on, and decided to drench me making it fall down so you could perv on me?"

Shit! I didn't even realise this. "What? no I didn't even know you were in the shower."

"Oh? really?" She said sarcastically. "Then why is your smirk so big? you're acting like you just won the lottery big brother." I was thrown by this; it's been a while since she called me that.

"Oh whatever, here" I said throwing her a dry towel. "It was only a glance of your tits geez, you know it was an accident."

"Sure, it was, it's a good job were even though."

Wait what? we were even throwing water on each other? Even though I saw her boobs? Win win! Or so I thought...

"By the way, did you completely forget about why you wouldn't wear those shorts on holiday?" She said as she was laughing manically walking back to her room.

"What? What are you talking about" and then it hit me, like a ton of bricks as I looked down at my still wet shorts which were pretty much see through. Shit, I'd never been so embarrassed in my life, let alone because...

"HEY THAT WATER YOU THREW ON ME WAS COLD YOU KNOW"

---------------------------------

The next few weeks or so was business as usual with life. After a night's sleep we both pretty much forgot about the situation. It helped that our parents came home so we didn't have to speak about what happened, especially in front of them. I didn't really have an issue with it, I mean I didn't really want to talk about the fact my sister had been able to see my dick for about 5 minutes in an extremely less than desirable state. I did think about her boobs a few times though, after all, to me they were pretty stunning, I know other guys like big boobs but for me that's just too much.

After the little incident I didn't really go back in the hot tub, I mean the water was only lukewarm so there was nothing really of interest to me, my sister however had taken to using it more frequently. It was a pretty hot summer, and she said that the heat from the tub made getting out nice and cool... Personally I've never liked the heat so I figured I could give it a shot, anything to feel cool.

Since my sister had been using it quite a bit, the water was pretty much always hot, so I figured this time I'd get in while it was hot, and definitely wearing different shorts! All black shorts to be more precise. I knew Chloe was in and our parents were at work, we all had full time jobs, but mine and my sisters' weekends were basically a Tuesday and Wednesday since we worked weekends.

"Chloe I'm getting in the tub, if you throw water on me again, I will actually torture you." I said with a deadly serious tone in my voice.

"Sure whatever, just make sure you're wearing real shorts this time," and then I heard a little giggle.

"Fuck you!" Shit I was hoping she forgot.

I went out to the tub, and learned all too quickly just how hot the tub currently was, I put one foot in and was pleasantly surprised. At this point it might be worth mentioning that the tub was only made for a maximum of 3 people, so it wasn't particularly big and so the water pretty much could stay at a high heat for a while even when switched off.

I had my headphones on and realised that the bubbles were getting them wet, I turned all the bubbles off so I could just lay there in the heat listening to music.

My sister mentioning my shorts was stuck on my mind, or rather me seeing her chest was currently on my mind.

I felt myself starting to get a little hard, but my swim shorts were tight, and he wanted to be free. I knew since because of the slats, that wasn't really a viable option. "Unless I turn the bubbles back on and then you can't even see below the water?" I thought to myself that I had just cracked the master code.

I thought I was being so smart, I turned the bubbles on and pulled my shorts off, leaving them in the water just in case. I decided to just risk it and keep my headphones on with the bubbles, I mean even if they got wet it should be fine right, so I just zoned out again with my eyes closed, my dick feeling nice and free. I couldn't help but think back to what my sister saw, in comparison to a normal day. I mean don't get me wrong, I am nothing special in that department or so I would say, but of all times to be exposed when I was cold?

But then I am rudely disturbed by water being flicked in my face.

"Huh" I mumble as I open my eyes and remove one side of my headphones.

"Move over dweeb I'm getting in!"

"What, why? I was nice and relaxed in here, you never get in when someone else is here," I said very aware of how naked I was.

"What's the problem, its big enough for 3 people in here, oh wait are you going to try and perv on me again? sorry I'm not into incest."

"Funny, I see your boobs for 5 seconds and I'm the one into incest, meanwhile my dick was pretty much exposed for 5 minutes and you didn't even tell me." I don't know why, but saying that started to turn me on a little and I could feel myself after recently calming down, starting to rise again.

"Your right bro that WAS funny huh" she said with a smirk, clearly taking a big at how small I was... Which I hated right now.

"Whatever, get in or don't just leave me alone." I did an eye roll and started to face away from her.

"Aww and here I wanted to play a game, maybe even show off my new swimsuit to you!"

At this point I actually looked at Chloe and realised she was actually in a bikini, a blue and white striped bikini which fit her body perfectly, it had little bows tied onto each hip and I was guessing the back was just one tie also. "This is bad" I thought, I'm completely naked (which she can't see) and she looks like that! Maybe I could just put my shorts back on? And then I remembered the last time I came into the tub and my sister said "no funny business." If she saw me putting my shorts on now, she would totally think I'd been jerking off in the tub! No way in hell that was happening. Okay, I'm just going to have to bear with it and stay in here longer than her, surely, she will get bored in no time and just leave...

"Why would I care about your swimsuit, I already told you I'm not interested" I said, not even convincing myself right now and blushing a bright red.

"Oh, okay then, good, I have nothing to worry about then!"

She sat down across from me and I put my earphones back on, every few minutes she would kick me and ask me something, or tell me some work gossip, clearly, she was bored... None of it was really interesting and to be honest I was too focussed on trying to make my dick calm down and not look at my sister. Until she started to get impossibly more antsy and childish.

She started throwing water at my face and my headphones were getting soaked, so naturally I had to take them off.

"Bitch what the fuck they're expensive you know!"

"I don't know what you're talking about, it was the bubbles just getting more violent."

I knew she was lying, because the bubbles didn't jump in my face the first 15 minutes I was out here.

"Oh, okay then," and naturally I retaliated by throwing water at her, which she did not like in the least.

"What are you doing dickhead, I don't like my hair getting wet in here!" She said in a high pitch screech.

"Oh, it wasn't me, the bubbles got more violent." I said with a complete shit eating smirk.

"Sure sure, not like I just watched you do it!" She proceeded to stand up, probably a little too fast, because she didn't realise thanks to the water, her bikini bottoms were pulled down a little and I got an eyeful of her treasure trove of a nice strip of brown pubic hair. Of course, she immediately realised and fixed it and I was quick enough to look away before she noticed me... but I was hooked. I'd never been with a girl that had any public hair, not by choice, but girl's these days like to keep it all shaven and I didn't mind either way, but if I had to say I had a preference, then neat pubes all the way.

"Shit" she mumbled; I knew full well what she was talking about but I had to act innocent.

"What now?" I asked pretending to be innocent.

"N... nothing, forget it!" She quickly left the tub.

"Thank God!" I thought, crisis averted and I could breathe. My cock was rock hard and the image of her pubes on my brain, I wanted to get out and go beat this monster away. Alas I was too slow to even put my shorts back on and my sister came back outside, she was carrying something but with my back to her I didn't see what exactly it was, it was just an intuition.

She sat back down, this time she was closer to me and I was confused about why she was closer, and what did she go get? Was it cold water? no it can't be, it wasn't a tub that she brought? And I thought I was safe, until she leans around the side and pulls out the fucking garden hose!

"I know you saw, now you must beg for mercy." She said in a humiliated tone of voice.

Fuck! "I don't Know what you mean, saw what?" I said, desperately not wanting to be sprayed by the freezing cold hose water.

"Okay then bro, looks like your time has come to an end."

And she lets lose the hose on the power setting spraying me, as soon as I felt the cold water on me, I had to stop it, I jumped across the hot tub and tried to wrestle it off of her, it wasn't particularly hard, but she was persistent.

"You bitch, why would you even do that, like what the fuck Chloe."

Still trying to wrestle she said "You saw and wouldn't even own up! Something had to be done."

I was done now... I didn't really want to wrestle with my sister, I didn't even realise the situation we were currently in but I wanted to end it.

I took the hose with one hand and with the other I dunked her head under water.

"Stop being a pain in the..."

Then I remembered I was naked... And I had just shoved my sisters head right into my raging hard cock. Luckily, I don't think she even realised it was my dick and she just fought off my hand pushing her under the water. She let go of the hose to use both hands to fight me. She was overpowering me since I still had the hose in my hand. She pushed me back against the side of the hot tub and I just got a face full of bubbles, followed by her chest being pushed against my face. I could feel my cock against her ass, it wasn't nestled between her crack but it was there and I was hoping to God she didn't realise it. I was so turned on I didn't want to fight back too hard or risk being caught and ending this little slice of paradise. I pretended to fight back, moving my hips to slightly grind against her, I could swear she was moving her hips to join me, but surely there was no way.

"Chloe knock it off you know I'm stronger than you, I will win," I said pretty much into her chest, still being pushed against me.

"No, you won't or you would have by now!" She was being persistent still.

Well, now that I took as a challenge! "Okay I guess it's go time then little sister!"

With all her weight on top of me, I stood up, her hands still griping both my wrists, her legs wrapping tightly around my waist as I stand, my dick feeling immense pressure as it feels like her entire weight is forcing it down.... all I could think was "surely she knows by now, surely she can feel my dick between her cheeks, surely she must be able to tell I'm naked."

Hang on a minute, naked? I realised I couldn't feel any fabric between my dick and my sister's ass, all I could feel was pure skin and wispy hairs?

Shit her bikini bottoms must have fallen off, is this a blessing or a curse? I was so turned on but no way in hell was I going to commit incest with my baby sister!

I fought my better urges and didn't push my luck.

"Well, well little sister, who's stronger now," I said trying my best not to sway my hips as I could feel pure warmth emanating from both our exposed groins.

"I don't know what you mean, I'm clearly the victor here!" Her voice extremely shaky.

"Oh, fine then, if this is how it's going to be," I said completely caving to the situation.

I let whatever happened next to be out of my control, I could not take it anymore, this terrible sister of mine was driving me crazy.

I jumped up with all the strength I had left to shake my sister, and I don't know if it was a mistake, or what my subconscious planned all along, but I could feel myself be enveloped by pure warmth, with a large moan from Chloe, it was so easy with little resistance... She was clearly crazy wet and it was not from the hot tub!

"Shit Chloe that wasn't supposed to happen. I am sorry." I said moving my hips slowly forward being unable to resist.

"You're going to be sorry mister" she said as she moaned "you Said incest wasn't your thing, and now you go ahead and penetrate my poor little pussy."

At the sound of the word pussy coming from my sisters mouth I could have orgasmed on the spot, right there and then inside my sister's cunt, but I didn't, I had to enjoy this and drag out whatever I could.

"Yeah, well, you don't seem to mind now do you sis" I said as I walked with my dick still sheathed inside her and placed her on the edge of the hot tub.

"Well right now you need to take responsibility for this little situation you have gotten us into." She said with a devilish tone to her voice.

Wait what? she wanted me to fuck her? really? I was not going to argue!

"Take responsibility huh, and how would you have me do that sis," I said as I pulled my cock out of her, so only my tip was inside. She moaned and I could feel her pussy tighten, begging me to fill her back up.

"You know full well how" she said, her mouth coming to my ear as she whispers "You better make me cum after you made me commit incest."

That was it, all I needed to hear. I slid my cock back inside her, as she moaned in pleasure, a wave rode over me and I knew that after all this build-up, I'm not sure how long I could last. I frantically and animalistically plunged my cock in and out of my sister, meeting her thrusts as she tried her best to reciprocate from the edge of the hot tub.

"Chloe, I can't believe your pussy is this good! I never even thought about this before, but damn you are sexy"

"Just shut up and fuck me!" She said begging me to carry on. I started pounding into her harder as she asked and I could feel her tense, which was only good news because I could not last much longer.

Then I felt her whole body convulse and she started to twitch, I could feel her pussy tighten and loosen around my cock and I couldn't take it.
