Back in 2015, we got snowed in with my big sister during a blizzard. Crazy strong winds and shitloads of snow. High school has closed before things got bad and mom got a text telling students not to come in for the week. Sadly the power was out, roads were closed, and the snow made it hard to open the front door.
Our parents were out of state visiting my grandma after an operation and my big sis was left in charge. Dad called and told us what to do and where all of our stuff was. We apparently didn't own a generator, the thing I always thought was it was in fact a broken A/C dad used for parts. We turned all the taps a little to prevent them icing up, pull the window shutters and close the curtains for insulation etc.
We were fine, plenty of food in the cupboards and plenty of snow to put in the chilled goods outside, plus I had a solar charger for my phone because I like camping. Also plenty of firewood and candles in the basement.
I used the fireplace log holder and a huge pasta pot to make myself hot water for a bath, but Sister also wanted a bath. Because the house is old we have one of those old cast-iron tubs that's a little wider and deeper than the shower tray tubs you see these days. It's good because it holds a decent amount of water and is actually meant for adults to have a bath in.
I joke and tell her she can either get in or make her own because this took an hour to make.
She says "Whatever freak, move" and gets in anyway. Oh we're really doing this? I stare at the wall whilst she gets in; she sits in front of me with her back to my chest and we laugh to ourselves because it's weird and we're smushed in together.
She jokes that with the candles and the dim lighting it's almost romantic in a weird way, and I joke that all we need now is banjo music.
"Ewww, that's too far! hahaha! I can feel your stuff on my back!" "Then get out!?" "Well I'm already in here now!"
This went on for a while, joking and calling each other freaks etc. She asks me if I'll wash her back seeing as I'm there anyway. Fine I will. She gets up and leans forward onto her knees to grab her washcloth from near the tap. I saw her ass and pussy for about 2 seconds illuminated only by dim candlelight but the view was excellent, innie slit, bald with just a slight bit poking out at the top.
Obviously I pop a throbbing boner. She says "Uhm... That better be a shampoo bottle?" "I wish it was" "EWWWW hahaha! What the fuck! Why!?" "It's because I saw your ass when you got up, you could have warned me to look away or something." "Wow, you weren't kidding about the banjos haha, I didn't know you were such a freak. Should I be worried?" I tell her to shut up and I can't help it, wash her back with the wash cloth, then we both shampoo and rinse, then get out of the tub and get dressed.
We joke about it and make banjo noises whenever things get quiet, making us laugh. Around 11pm I get tired of reading, put out the fire, take a candle and go up to go to bed. Power is off, so no heating at all, it's really inside. It is so far below freezing that as soon as the residual heat from the chimney breast is gone it's ridiculously cold, I can't stop shivering. I didn't own any thick pyjamas because A/C and they were uncomfortable, but I wished I had them with how freezing it was.
10 minutes later my sister opens my bedroom door and asks "Hey, you awake? There's no way you're asleep yet." "Nope, far too cold." "Then move over because I'm freezing in my room!"
With two of us under the sheets the bed starts to get a little warmer. As the room falls silent again for a few moments, she makes a banjo noise again. We both start laughing, "First you get into my bath, now my bed? Da-da-dang-dang-dang!"
She nudges me and says "You're the one getting a stiffy seeing my ass, Cletus."
"You're the one who put it in my face, Brenda-Lee."
"Whatever you say Cletus, maybe I should put 2 pairs of shorts on for safety."
"Better make it three, and a belt."
"Wow Cletus! That good for you?"
"Oh yeaah. Better stop making me think about it or you'll give me a shampoo bottle."
I start laughing again with her wheezing "what the fuck, you're so gross!"
Laughter dies down again and after some more jibes here and there we fall asleep.
I woke up around 10am, get up and go about my day, mostly just shoveling the snow off the driveway and backdoor patio onto the lawn/garden, reading, charging our phones, calling mom to let her know we're fine, keeping the fire burning etc. Sister helps out with the shoveling but mostly sits around reading because there's just nothing else to do.
Night time rolls around again after an uneventful day mostly trying to keep us warm and fed. I smell like sweat because of the repeated shoveling to keep the driveway clear. Fill up again the pasta pot a few times, wait for it to boil, take it upstairs, fill the tub until it's full and hot, light the candles on the sink. Get in.
Hear stomping up the stairs, then the door knob turns:
"Da-da-dang-dang-dang!" We start laughing.
"Do you mind?" Tell her fine just don't be weird about it; she gets in and we soak for a while in silence, the back of her head to my face, her back between my spread legs.
"This is weird." she says, giggling.
"Yesterday you said it was romantic?"
"Cmon! you're making it worse!"
"Then wait and make your own bath?"
"Noooo I'll drop the pot and burn myself!"
"Then deal with it." After a bout of silence, she says "Can you imagine telling anyone about this?"
"No fucking way!"
"See? It's weird!"
"I know it's weird, I'm just going with it."
"Like, no matter how you tell it, it's pervy, right?"
"You make it sound way worse, we're just sharing a bath. We did this all the time when we were little."
"Yeah but you were little and cute and I didn't have boobs or hairs."
"From what I saw yesterday you don't have any hairs."
"Well I do."
"Not from behind you don't!"
"Ewwww it's on the front you perv! How hard were you looking!?"
"Shampoo bottle hard?"
"What the fuck!? Why!?" she says as she laughs.
"Why are you telling me about your 'scaping?"
"You asked!"
"I didn't! You're just here telling me about your landing strip or whatever!"
We had a good laugh, then abruptly whilst the laughing was slowing down she stopped and said "You know what? Screw it. You already saw. Let me grab my cloth." She grabbed the sides of the tub and pulled herself forward onto her knees and lingered for a few moments longer than last time before snatching her washcloth and sitting back down.
I'm instant hard as diamonds, and it's pressed against her back. I'm speechless, can't think of anything, she did it on purpose this time and I'm not sure how to take it. My heart is racing, I got a really good look this time. Her ass really was perfect, round but firm. She's quiet too, probably embarrassed and scared that she stepped over a line. The room fell silent as we both sat still in the water. After a moment or two I blurt out "h-hah, you better put your washcloth on the sink next time, if you lean forward again, this is gonna go from PG15 to R real fast."
She very quietly said "nah... you wouldn't."
"... I'm kinda serious." My heart was pounding so hard at this point, like I knew she could feel it on her back. There was no way she couldn't.
She had to have known she was playing with fire.
"No you're not... watch." After a moment she very slowly leaned forward again. As her ass rose out of the water, my heartbeat suddenly got faster and harder. My cock was rock hard and pulsing because of how hard my heart was beating, as the water trickled down her thighs I saw her push her knees to the edges of the tub. It was like she was daring me to do something.
That was it for me. You know that feeling that you're about to do something seriously fucked up? That pull from pit of your stomach feeling that tells you what you're doing was wrong? Like when you place a stupidly risky bet? I could feel it and it was telling me to stop before this went too far, but as strong as it was I couldn't ignore what was in front of me.
I got up onto my knees and positioned myself behind her, she stayed perfectly still. As I grabbed her ass she flinched a little, but then pushed it back so that her lips pressed on my cock, it was wet, warm and I could feel it. Any semblance of sanity was gone at that point.
I wanted to give her one last chance: "You're gonna chicken out. I know it." I grabbed my cock and traced it up her slit until I felt the opening, then pushed myself in, her letting out a deep moan mixed with "ohhh-oh-ghad" as I slid in all the way to the base, after taking a very quick moment to realize what I'd done I began pumping her.
Slow at first, then grabbing her sides gently I started going harder, she was so wet and tight my cock was gliding and she was so hot inside I didn't care at all about of cold the air was. She was holding the sides of the bath, panting with every stroke, pushing herself back to meet every thrust, as we got more into it her breathing got louder and heavier. I could feel my balls slapping against her pussy with every thrust. I could feel her tightening up and bringing her knees in, and it brought us to the edge.
As she started shaking and cumming I grabbed her hips tightly, pumped deep until I could feel I was right against her cervix and blew my load. As I came, she shuddered harder and started panting louder, pushing herself firmly against my cock as I pumped my load into her. It was the most powerful load I've ever shot, nothing in my life has ever come close to that, I was in pure primal ecstasy.
I stayed inside her for what felt like ages, She was holding herself up with her arm over the edge of the tub and the other holding the tap. As the adrenaline wore off I slipped myself slowly out of her, watching her pussy closely as a big glob of cum slowly came out of her and dropped into the bath water.
"Inside?" she said, catching her breath and composing herself.
"Yeah, hah..." I said, pulling her down on top of me, back into the water.
"You better hope nothing happens, genius." What did she expect? With this primal fuck I didn't even think of pulling out. From the moment the tip of my cock touched her pussy there was no way I was going to pull out ever. She also pushed herself against my cock hard as I was cumming, so there's no way she didn't know what was happening.
As we came to our senses, I noticed the water was getting cold. So after a few minutes we got out, awkwardly toweled off in the dim candlelight, with a jab or two at what just happened and went downstairs to warm up by the fire.
The tension was thick and uncomfortable. We both knew we crossed the line and did something we couldn't take back, I wasn't sure how she felt about it and it made me feel a little nervous and guilty. After a few minutes of nervous, awkward silence sitting next to each other on the couch I just decided to break the silence, lay my cards on the table and said "That was way hotter than it had any right to be."
"RIGHT!?" she blurted "What the hell was that!?" Thank fuck she felt the same.
I continued: "I know it's fucked up, but it felt amazing. I never thought that could ever happen."
"Same! it was, agh! but, just, woah, y'know!?" She did her little fast tip-toe tapping thing on the wooden floor that she does, my sister really only does that if we're watching a really exciting movie or she's retelling a really crazy story or something so I knew she was being legit about it.
"When I got up after you I was half expecting you to turn around and clock me."
"HAH! I was teasing! I was dead sure if I got up again you'd chicken out. When YOU got up I thought you were trying to psyche me out!"
"Really?"
"YES! When you went in I was like "ohhhh my fuck he's really doing it! what have I done!?"
"So why didn't you push me off?" She sat there looking down smiling at her hands for a sec, then quietly said "I dunno, I just... didn't." then smiled at me and shrugged.
Hearing that got me going again a little, but I didn't want to push my luck so soon. I couldn't believe I'd just railed my sister. As awesome as it was it wasn't a story I could ever tell anyone. It was a strange feeling. I think above all else in that moment I was just glad that things were still relatively normal between us and what just happened didn't fuck up who we were to each other and make things awkward.
I put my arm around her and said "Well, I'm glad you didn't." She smiled and then rested her head on my shoulder and took a long, relieved sigh. She sat with her phone as she leaned on me. I sat with my thoughts and watched the fire for a while, which was interrupted by her saying she was going to go to bed whilst the fire was still burning and her room wasn't freezing. I went up around an hour after her, putting the fire out taking a candle up with me so I could find my t-shirt and bed shorts.
After I got dressed and got into bed, the gravity of the situation hit me and I couldn't settle. What if she does get pregnant? What if shit changes? What if she starts to hate me? Stuff like that just kept floating around, preventing me from sleeping. Before I knew it the heat had dissipated and the sheets just wouldn't get warm enough to be comfortable.
Eventually I heard noises from across the hall, so I knew she was awake too. I just stayed in bed and didn't disturb her figuring that she'd gotten up to take a piss or something. There was more noise, like pacing, until finally my doorknob started turning.
"Hey, you awake?" she whispered.
"You too cold to sleep too?" I answered back.
"Freezing." she sighed. "It's like a morgue in there."
She just kinda stood there at the door, I could tell she wanted to ask but felt weird about it with what happened. So I spared her the embarrassment and just asked "It got warm enough with you in here last night, wanna join me?"
"Yesss." she groaned as she play-stomped over to the bed and hopped into the covers.
I figured with how awkward she was being she would have wanted to sleep back to back, but she got in front first and wrapped her arms around me as she shivered saying "Warrmmm me upppp!" as she jostled for the warm spot I'd made with my body heat. Her nipples were hard from the cold and I could feel them rubbing my chest through our shirts.
"I can tell you're cold!" I joked.
"What? Oh. Hah, Shut up, don't be gross, yours are too, see?" She pinched one and I let out a fake "ughnn!" We both had a little laugh and she called me a dickhead, then hugged me tighter as the laughter died down. As she stopped shivering and settled in the sheets got nice and warm enough, and before long she was asleep. Having her in my bed snuggled up to me and snoozing kinda mellowed me out and stopped me overthinking things. The thoughts came and went until I fell asleep.
When I woke up it was morning and she'd gotten up to go to the bathroom. As the toilet flushed she was quickly shuffling back into the room whispering "cold cold cold cold!" and then raced into the sheets and snuggled back up to me shivering, wrapping her ice cold fingers around me.
"AGHH!" I yelped as she pressed them directly onto my sides.
"Sorry!" she squeaked "I didn't think!" As I was wide awake I got out of bed to go and start the fire, then came back upstairs and hopped back in whilst the house warmed up.
"You don't have to face away you know" she said from under the duvet.
"Don't want your ass in my face?" I said, jostling it around.
"Haha, no you're just warmer on the front!"
"ohhh" I said as I shifted myself around onto my back, and as soon as I did she threw her arms and head onto me and let out a loud "AHHHHH!!" and wiggled playfully under the sheets. I sat and started reading the local news on my phone, until my sister piped up.
"If the power still isn't on tonight, can we share again?"
"The bed? Yeah."
"... no. the other thing." As soon as she said it, my heart started beating faster and the beast below started perking up
"Sure."
She had her head pressed against my chest, so she must have heard the reaction. She giggled kinda smugly and joked "oh so it's like that now is it?"
"You have a nice ass. Sue me."
"Eww you have a crush on me now or something? That's sick."
"Shut up. You liked it too."
"Yeah as like a one time thing!" Then she pushed her arm down until it hit my cock and said "EWW I knew it! you're hard! You were thinking about it!"
She laughed and wriggled around and I smushed her head onto my chest whilst she laughed trying to conceal my embarrassment.
"Can I touch it? I didn't even touch or see it last night."
"OK perv. Go nuts!" This couldn't be worse that the bath episode, right?
"Fine I will!" She wasted no time reaching into my boxers and gripping it tightly
"It's so weird!" Of course she started trying to jerk it and my abs jerked in response
"HAHAH! Wow that's wild!"
"Are you trying to jerk me off?"
"No I'm just playing with it!"
"He doesn't know that!" She put on a stupid voice and shook it as she said "I'm just playing with you!" I reached down into her shorts and grabbed her ass cheek in retaliation.
"HEY!" she giggled.
"Hey yourself!"
"You know what? It's getting toasty in here"
"Wanna get up?"
"Nah, watch this." She rustled under the covers for a moment, then put her head back on my chest.
"What did you do?"
"Nothing." she giggled.
I went to grab her ass again and noticed that there was no pyjama bottoms, she'd taken them off! She gripped my cock harder and giggled mischievously. I reached down lower between her thighs and she was soaking wet down there.
Without saying a word I put my head under the covers, got on top of her and stared into her eyes. She had this devious, cheeky smile on her face.
"Well? What are you gonna do?" She asked grinning at me. I pulled my T-shirt off and she did the same, giggling and smiling. She pulled her legs up and rested them on my back. my cock was just below her pussy so I reached down and put it in position. She reached around the back of my head, and as she pulled it down I pushed my cock into her slowly and she let out a deep, hard moan as she gripped the back of my neck and my side.
Her body was roasting hot and in the moment I just couldn't think. Our bodies were so close I could feel her tits bouncing lightly against my chest as I was pumping deeper and harder than I did the night before. She was so wet and warm all I could think about is how amazing it felt. She was underneath me, gripping me hard and writhing underneath me, every thrust was met with a loud, horny moan and as my head was right next to hers it was super loud and it drove me wild.
As we went at it more, I could feel her tightening up and digging her nails into my back, then as she went over the edge she dug her nails into my back as she hugged me hard and locked her legs around my ass as she shuddered and came. Her pussy tightening up around me, I grabbed her breast and started pumping faster and harder, I could feel and hear my balls slopping against her pussy as her moans got shallower and quicker, then in six long, hard strokes I emptied everything I had into her. I could feel powerful, thick ropes surging through my cock in every thrust.
Finally I lay down on top of her, completely spent, She was smiling as she was catching her breath, petting my hair and giggling between breaths
"Are you trying to knock me up or something?" she laughed.
"No"
"You've GOTTA stop finishing inside me." I smiled on the inside when she said that, the implication being that she didn't think this would be the last time. Of course, I didn't want this to stop anytime soon either. As fucked up and twisted as it was, it was the best.
No promises"
"OK Cletus." she smiled, "When it comes out with a tail you can explain it to mom."
"That's fine. It'll play the banjo." She burst into laughter and said "Ewww! C'mon! Don't say that! You're still inside me!"
As I got up to slide out, she pulled my head down and gave me a long, wet kiss on the lips, then stuck her tongue in my mouth. As she awkwardly swirled her tongue as she smiled, I got instantly hard again.
When she felt it against her thigh she laughed "Think you can let me clean up a little first?". I smiled and traced my cock up her slit, "Guess that's a no!"
We fucked a couple dozen times over the three days until our parents managed to come home.
When they were back, we'd run to my room and strip off any time we could; in her car under the pretense of getting Wendy's, sometimes in the basement behind the stairs.
It's never stopped.
