[Fiction] My Step-Sister Becky

[coderider]

This is my first post, and the first time I've ever posted a story online. I've written before, but I've never posted anything.

I'm curious to know what you think. Please give me your feedback.


================================================== =

Chapter 1

When my dad started dating again a few years ago, I was a little freaked out. Ok, I was freaked out A LOT. But now, I'm glad he did. He's much happier now. And so am I.

My name is Brian, and today, I'm 16. My parents got divorced when I was twelve. Most of the things I remember about my mom are not good. I remember a few good things, but dad says even on her good days, mom would usually mess things up with her drinking. Eventually my dad got tired of the chaos, so he moved out of the house and took me with him. Mom's never been part of our lives ever since then.

But that's ok. Because now I have a really cool step-mom. And an even cooler step-sister. Becky, my step-sister, and I have grown quite close. She's also 16, and in the same grade as me at Truman High School. We look nothing alike, and we have fun telling people we're "twin" brother and sister. It's funny watching people look at us, trying to see the resemblence. We just smile and don't bother to explain. We figure it's none of their business.

When Becky and I first met, it had been after dad had been dating Angie, my step-mom, for several months. Dad has always been very open and honest with me, and I could tell things were getting pretty serious between them. I just wanted my dad to be happy, so I accepted Angie and Becky.

Growing up as an only child, I'd always wanted a sibling, and the prospect of having a sister was very interesting to me. But when I met Becky for the first time, I was stunned. Becky was beautiful. She had shoulder length, straight brown hair, chocolate brown eyes, a thin face and a smile that could melt steel.

I wasn't prepared to be attracted to my sister. Your sister isn't supposed to be HOT. And she's only gotten better looking since we first met. More about that later. I don't want to get ahead of myself.

So dad and Angie got married. Becky and I became brother and sister. We were both 14 at the time. Shortly after that, my dad took a big promotion with his company, so we moved to a new town. This drew us closer together as a family, since we didn't know anyone in the new town.

Becky and I accepted each other as brother and sister. I tried to hide my attraction to her, but it was no use. It was that smile of hers. She would look at me and smile and I'd go weak in the knees. But I'd always play it off, and play the silly goof role. Which of course made her laugh and smile at me more.

We moved to our new house during the summer while school was out. Our new house was huge, with a secluded pool and a big back yard in a pretty exclusive neighborhood. My dad must have been bringing in the big bucks to afford a house like this. Angie was very busy establishing herself in the local real-estate market, so Becky and I found ourselves alone in the big house frequently.

It was a hot July day and both our parents were gone. With nothing better to do, Becky and I found ourselves outside in the pool. Becky, of course, looked fantastic in her swim suit. It was a cobalt blue suit, and actually quite conservatively cut. It wasn't the suit that made Becky look good, it was Becky that made the suit look good. Becky was very fit for her age. She was several inches shorter than me, but her breasts were beginning to swell from her chest. She was already at least a B cup.

At first we swam tentatively together, but before long we were splashing each other, playing some friendly volleyball and playing h-o-r-s-e with the in-pool basketball hoop. And then things got more competitive with a game of one-on-one basketball.

Becky was a good shooter, but eventually I took the lead by several baskets. She was starting to get frustrated because I was beating her to all the rebounds. I'm a pretty good swimmer, having been on the local swim team back in my old town. I was the second strongest on the team, which was really good when you consider that most of the other guys were two years older than me.

I had started puberty at around 9, which is way early for a guy, so for 14, I was pretty developed. I was already 5'8", had a lean build and I was already shaving.
I surged ahead of Becky to get yet another rebound, when suddenly my swim trunks were around my knees.

Becky squealed with delight, and covered her face with her hands. Everything but her eyes, which were grinning at me as she laughed behind her hands.

"Hey!", I said. "That's a foul I think!", as I quickly pulled my trunks up.
At first I was kinda mad, then I was just embarrassed.

"I'm so sorry!", Becky laughed into her hands. "I had no idea your trunks were so loose."

Any upset feelings I had quickly left me as she laughed and smiled at me with those big brown eyes.

"I'm really sorry. I didn't know that was gonna happen. I swear!" she said.

"No big deal. Now you've seen my best side," I replied. I turned and shook my butt at her under the water.

She jumped on my back and threw her arms around my neck. I pretended to panic and flailed my arms and call for help as Becky clung to my back. I could feel the swell of her breasts rubbing up against my back as hung on and giggled at my antics. We wrestled around in the water for a bit, which felt strange, because even though we were now "brother and sister", we'd never actually touched each other until now.

But at the same time, it was strangely comfortable and natural, since it was my sister I was wrestling with. I let Becky dunk me few times and she sensed that I was giving up the game. As I came up from out of the water, she had the strangest smile on her face.

"I know something I can beat you at," she said.

"I doubt it," I laughed.

"No really. I bet you I can," she said.

"What is it? Toenail painting?" I cackled.

"I'm not gonna tell you. You have to bet me first," said Becky, grinning as if she knew something I did not.

"Is it a sport?" I asked.

"It's definately a sport," she said. "Do you wanna bet me?" she smiled. Then sticking out her lower lip she challenged me with mock baby-talk. "...Or is the big boy too chicken?"

OK, I was feeling a little annoyed at this point. What did this girl think she could beat me at. There was no way. I was bigger and stronger than her in every way. Becky did have a natural athleticism to her, but... there was no way she could beat me at any sport I could think of.

"It's a real sport you say?" I said, still suspicious.

"As real as any Olympic sport," she replied, the began clucking like a chicken and laughing. "Come on, bet me chicken."

"OK, OK," I said. "I'll bet you. How much? 10 bucks?"

"Nah," there was that smile again. "Something else..."

"What then?"

"The loser has to do whatever the other person says," she smiled.

"No way!" I protested, "I'm not doing your laundry or washing your feet or any crap like that."

"What's the matter? Chicken?" she replied and started with the chicken noises again.

"Besides," she added, "If you win, then I have to do whatever you say."

Well. I liked the sound of that. Besides, I knew I was gonna win.

"OK, I bet you," I said, sealing my fate. "Shake on it," I offered my hand to hers. "And you better not weasle out of it when you lose."

"Don't worry," she said, shaking my hand. "I won't lose."

So with the bet made and the handshake out of the way, I asked. "So what's the sport?"

"I bet you that I can do a better dive from the diving board than you can," she said smiling.

So that was it? That was her ace in the hole? I smiled back at her, because I had done a little diving myself, before I'd decided to concentrate on swimming. And she didn't know that.

"Oh, this is gonna be easy," I said. "Ladies first," I held up my hand and offered her the diving board.

"Oh no," Becky said. "We bet I could do a better dive than you. So you have to go first."

I hesitated, feeling like I had just been suckered somehow.

"OK, we'll do it your way," I said, before she could start with the clucking noises.

I swam over to the side of the pool and climbed up the ladder. Water streamed off my body as I strode confidently to the diving board. The best I could do was a one and a half summersault with a full twist, back when I was diving. But sometimes, I'd blow that dive too.

I turned my back to Becky, and went through the motions in my mind. Could I do it? Or should I just play it safe and leave the twist out? I hadn't practiced diving in over a year. If I failed the dive, I'd flop into the water out of control, making it easy for her to beat me. I practiced the dive once more in my head, and decided to go for it.

I turned to seeing Becky's wet head bobbing in the water as she smiled at me. I quickly blocked her out and focused my dive. I walked to the end of the board, and bounced a little, getting a feel for it's strength. Then went back on the board, focused, strode forward and sprung into the air.

I nailed it! As I felt my feet slip under the water, I realized that it may have been the best dive I've ever executed. When I surfaced, I heard Becky clapping.

"Whoa! Nicely done Brian!" she beamed. "That was an excellent dive. One and a half summersault with a full twist?" she asked.

"That's right!" I beamed back. Then it hit me. How did she know that?

"Well, I'll see if I can beat that," Becky said, climbing up the ladder.

"Hey!" I said. "How did you know that was a one and half full twist?"

"Hmmmm..." she said, pretending to be stumped. "I guess you're not the only one who's had a little diving training." And there was that smile again.

Becky looked totally amazing standing there on the diving board with water dripping from her darkly tanned skin. Her nipples puckered in the air and showed clearly thru her suit. But I didn't see any of it. My mind was reeling with the new knowledge that my "twin sister" may be an expert diver. Watching her confidently set her body for the coming dive, I knew I was in trouble.

She stepped forward and launched herself into the air and completed a perfect two and half summersault single twist dive, creating almost no splash as she entered the water. It was truely an awesome dive. I knew my goose was cooked.

Becky surfaced and swam over to me. Smiling the whole time.

"What did you think of that?" she asked.

I held out my hand. "Congratulations. You win. Your dive was way better than mine. More difficult and better executed. What can I say." I forced a smile. I didn't like losing.

She took my hand and held it for and awkward amount of time. But her hand was so warm and so soft, I didn't mind it.

"So what do I have to do now? You're dishes for a week?" I cringed at the thought.

"No..." she laughed. "Nothing like that," she said. She grinned from ear to ear.

"Well what then?" I asked.

"You have to..." she paused. "Forget it. It's stupid!" she said.

"No, I lost the bet," I said. "Fair is fair. I'll do what you say."

"You're gonna think it's stupid," she insisted. "And you won't do it any way. And then I'll feel stupid for saying it."

"No, really Becky. I'll do what ever you say."

"You won't laugh?" her eyes pleaded.

"I won't laugh. Just tell me what I have to do."

"Ok," she swallowed hard, building up the courage. "You have to swim from one end of the pool and then back again while underwater the whole time."

Well that's not so bad I thought. I do that all the time.

"And you have to do it naked," she blurted out.

I looked up at her as she sat on the side of the pool. Her eyebrows raised in a question, waiting to see if I would make her feel stupid. I did the only thing I could. Without a word, I collapsed under the water and swam to the shallow end of the pool. I looked back at Becky, still watching me with raised eyebrows.

"You sure about this?" I asked.

She nodded, and that smile started sneaking back in her eyes.

"OK. Here I go".

In one smooth motion, I removed my trunks under the water. I had been skinny dipping before, so I expected the glorious feeling of being nude in the water. I'm not sure why it feels so good, but I'm glad it does. Knowing that me sister was there in the pool with me, watching me, made it all that more exciting. I felt myself bobbing between my legs as I took a few deep breathes, and then plunged under the water.

I have no idea what I looked like as I moved myself under the water, but I could feel my penis bumping against me as I swam. As I quickly reached the deep end, I realised that I was swimming very fast without the suit to drag me down. I should have been able to make it back to the other end with ease, but with the excitement, my lungs were demanding air. Now!

Almost in a panic, I surged the last few meters, touched the side of the pool and popped up, gasping for breath.

"Good enough," I panted as I turned to face Becky.

"Yep," she grinned. She was staring at me. That's when I realized that the water wasn't covering my crotch, and she was staring right at my exposed nakedness.

I plunged my butt back under the water. Becky laughed through her hands that were now covering her face. I was too emarassed to speak. My sister had just seen me naked! As I reached for my trunks, there was a noise for the direction of the garage.

"Hurry!" Becky called quietly. "Someone's home!"

I scrambled back into my trunks and as calmly as I could swam over to the basketball. Becky slipped back into the pool and made her way under the basketball net.

As my dad came around the corner with his briefcase, Becky called out, "Four - Three - Two ..."

Instictively I shot the ball at the basketball net. As it looped thru the air, Becky finished the countdown.

"One - RRRRRRR - The buzzer sounds!" she called out, just as the ball went thru the basket.

"He makes it! The crowd goes wild!" I yell out in my excited announcer voice, as Becky let out a "Wooo wooo!".

Dad walks up to the edge of the pool. "Hey you two. Sounds like your having a good time."

"We sure are," beams Becky, a little too enthuesiastically.

"Well, you guys need to get out and dry off. Mom's bringing home Chinese and should be here in a few minutes," my dad says. He's in a good mood and I can here it in his voice.

"Maybe after dinner the four of us can get in the pool and continue the game you and Becky were playing," he says as he walks into the house.

I look over at Becky, and her eyes are as wide as mine.

"Somehow, I don't think that would be a very good idea," I mumble so only she can here me. We bust out laughing together.

Chapter 2
----------

That night at dinner was extremely awkward for me. Mom and dad talked about the usual stuff; work, the house, preparing for the new school year and stuff like that. I was kind of quiet and still feeling weird about Becky seeing me naked in the pool like that.

Every time Becky looked at me she smiled with this gleam in her eyes. I could swear she was thinking about seeing me naked every time she looked at me.

"Are you ok, Brian?" my dad asked, shocking me out of my own thoughts. "You seem quiet tonight. Is everything ok?"

"Yeah, I'm fine," I said, shrugging off his question. How do parents do that? It's like they have this sixth sense to know when something is going on.

"Maybe he got too much sun in the pool today," Becky giggled. I joined her with nervous laughter. I had to admit, that was funny.

Later that evening, as I walked by Becky's room, I heard Becky talking on the phone with one of her girlfriends that still lived back in our old town. Was she telling her about seeing me naked!? I knew I had to put a stop to this.

I pushed open her bedroom door, went in and flopped down in the chair opposite her bed. Becky gave me a dirty look as listened to her friend on the phone. I knew that I was being rude, but I didn't care. As I listened to the one-sided conversation, it was clear to me that they were talking about nothing more than clothes. Annoyed that I was in her room, Becky apologized and ended her conversation on the phone.

"Rude much?" she asked.

"I..." I didn't know what to say.

Becky's eyes softened. "Hey, if you're worried about the pool this afternoon, don't be. OK? Everything's fine."

"It's just that every time you look at me, I think you're thinking of me naked," I blurted.

"I am," she smiled.

My jawed dropped and my eyes must have been popping out of my head.

Becky laughed. "Don't worry," she pleaded. "It's cool. You looked fine."

"Fine!?" I repeated.

"I mean... You looked good," she offered, trying to clarify.

I couldn't believe I was having this conversation with my sister. I looked at her, stunned. Then she realized what she had just said, and her eyes looked down and she started blushing. Finally, I wasn't the only one embarrassed. She looked up at me with beautiful brown eyes, smiling. We laughed nervously together.

"So..." I said, nervously rubbing my knees as the laughter subsided.

"Look, I'm not going to say anything to anyone, ok?" Becky offered.

"Promise?"

"Yes, I promise!" she smiled. "Just don't be weird about it, alright?"

"OK," I smiled back. As I stood to leave, she got off her bed and hugged me with one of those sisterly hugs, like she had done a hundred times before.

"Everything's cool," she smiled.

"I'm relieved," I sighed. "I thought that..."

"Don't worry about a thing," she said, gently shuttling me out the door of her room.

"OK. Thanks for being so cool about this," I said from the hallway.

"Not a problem. Have a good night Brian. Maybe we can swim some more tomorrow," she said, smiling as she shut her bedroom door.

---

The next day was another hot one. Just another hot July day. Accept I kept thinking about going swimming. But my Dad was working from home, so I didn't even bother suggesting it to Becky. The day dragged on. I was killing time playing on my Xbox, when Becky stuck her head in my room at about 2:00 pm.

"Hey, wanna go swimming!" she asked excitedly. I turned and noticed she was already in her suit. "Dad just left. I'll meet you in the pool!" She darted off, not even waiting for my reply.

When I arrived at the pool, Becky was laying on a large air float in the middle of the pool. I knew I shouldn't be thinking it, but she looked sexy. She was wearing her blue one-piece again, and I could see the swells of her breasts topped by the subtle bumps of her nipples. What really drew my attention was the mound that formed below her flat stomach and swelled to the split of her legs.

Becky's head popped up and she looked at me. "What are you doing?" she smiled.

Stunned out of gawking at her, I knew I'd been busted for staring. I did the only thing I could do. I tossed my towel on the nearest chair and threw myself into the pool, yelling like I was a madman possessed. The splash and wave knocked Becky into the water, and this lead to the inevitable splash fight and squealing.

After 10 minutes of that, I swam several laps in the pool to burn off some excess energy. Becky joined me for a short time, but swimming isn't her thing, and she stopped after a couple of laps. When I finished, I leaned my back against the side of the pool to catch my breath.

Becky climbed up the ladder in the deep end and went to the diving board. She looked glorious in the wet suit. As I began swimming to the deep end, she set herself at the end of the board, and executed another near perfect dive. She surfaced only a few feet from me, and we treaded water together, slowly circling each other.

"So, you think I look good, huh?" I asked. I had been trying to figure out how I was going to ask her that question. I chose the throw-it-out-there approach.

"I knew you were gonna ask me that!" Becky's eyes were wide. "Why can't I just keep my big mouth shut!"

We circled in the water for a few more rotations before I was finally forced to pursue. "Well?" I asked.

"I'll answer you, but then you have to answer a question for me," she said, smiling.

"Oh, a little game of Truth or Truth?" I joked. "Why don't we just get right down to business and play Truth or Dare?"

"Yes," she said.

"Yes you want to play?"

"Well, yes, that to. But yes to your first question," she smiled and looked at me, waiting for it to sink in.

"Oh...." I said. Then "OOOHHHH..." I said louder, fully understanding the meaning of both.

"So now answer me this," she hurried on, as if trying to change the subject. "Do you think I look good?"

Her plan worked. She threw me off guard with her question, and I was immediately trying to figure out what to say. I suddenly realized how difficult it must have been for her to answer the same question about me.

"Well?" she asked.

"Yes, you look good," I blurted out. I knew it was no use. I was going to have to say it sooner or later.

We circled each other in the deep of the pool for a bit longer, not making eye contact. I looked at Becky, and when she finally looked over at me, we both started laughing.

"Look, I know I'm not supposed to think stuff like that about my own sister", I started.

"It's ok," Becky said. "We're obviously thinking along the same lines. So if we're weirdos for thinking it, then we're weirdos together." She mad a weirdo face and so did I, and we laughed together again.

"So what made you think to ask me to swim without my trunks in the first place?" I asked.

"I dunno... Sometimes my mind just jumps to these weird thoughts.... Ok?" Becky said. I could see she was a little embarrassed.

"OK, you're turn to ask me a question," I said, letting her off the hook.

"Ok..." she paused and searched for a question. “Have you ever swam naked before yesterday?"

"Yeah, twice before", I said. Once with my dad at the lake, we were by ourselves and it was night time. And a week ago in this pool. I snuck out late at night, nobody was around, so I ditched my trunks."

"Man... You're bold," she said, shaking her head. "I'd be too scared."

"I was at first, but then I realized it was no big deal", I said.

"I dare you to do it again!" Becky challenged me, her eyes browse raised.

"Wait a minute," I said. "You asked the last question, so it's my turn to ask you. Besides, everyone knows you can't make the same dare twice when playing truth or dare."

So the questions began to fly, as Becky and I asked questions we never thought we could ask anyone. I learned that Becky and kissed two boys before, she masturbates almost everyday, she's never been past first base, I'm the only "boy" she's ever seen naked other than pictures, she has pubic hair and she doesn't shave it, and she thinks me and my dad are good looking.

Of course, I had to share the same. I had kissed only one girl (a quick kiss), I masturbate at least once a day, barely been to first base much less second base, I saw a naked woman once when I spied on my old neighbor in her bedroom, I have pubs and don't shave either (of course she knew that already), and I admitted that I thought she was hot. And her mom was not bad either.

I was getting tired of the truths, and decided to try a dare on my next turn.

"I dare you to take off your suit and swim from one end of the pool to the other," I said, trying to sound casual.

"Oh no," Becky protested. "You can't make the same dare twice. You're rules."

Dammit. She was right. So I shifted my thinking into high gear. "I dare you to take off your suit and then do a dive from the diving board naked," I said. Again, trying to sound as casual as I could.

Becky looked at me, her eyes searching my face. I could tell she was debating on whether she could trust me. I expected her to refuse. Without a word, she swam over to the ladder, and with her back to me, she slipped her swimsuit straps off her shoulders and removed her swimsuit. I couldn't believe she was doing it.

She ascended the ladder and I watched as the water slid down her naked back and bottom. Without looking at me once, she walked over to the diving board. Her breasts bounced slightly with each step as I looked at her budding nipples that were puckering into hard nubs. As she turned toward, my eyes greedily drank in the dark curls of her pubic triangle.

Without hesitating, she expertly hopped on the end of the board and launched into the air and completed a simple one and a half summersault dive. I blinked, hardly able to believe the beauty my eyes had just seen. She surfaced near me and her eyes were searching my face, looking for my approval. I smiled at her.

"That was awesome!" I said finally. "You are truly amazing! And beautiful!" I insisted. The relief on Becky's face was obvious, and she smiled.

"Now it's my turn," she said. "You have to take off your suit in the shallow end, then get out of the pool and walk to the diving board and then dive in." She smiled big at me, pleased with herself.

Of course, I knew I had to do it, so I swam over to the shallow and removed my suit. I looked back at Becky as I climbed the steps out of the pool, and watched her as I walked all the way around the pool to the diving board. She was smiling broadly as her eyes darted over my naked body. I felt a tingle in my penis as it began to stiffen as she stared at me.

I stepped up on the diving board, feeling the air on my naked ass and feeling myself bobbing freely in the air. I step forward and with a single jump and sprung into the air and did a simple head first dive into the water.

As I swam over to Becky, I realized that she was still naked under the water. When I surfaced, I found her smiling face waiting for me; her hand extended high waiting for a high five.

"Nice job bro," she said. I high-fived her.

We spent the next 10 minutes swimming naked, enjoying the excitement and laughing and giggling at each other. Then we decided to put our suits back on, before our parents came home.

I realized later that afternoon as I showered before dinner, that the summer might be almost over, but the fun with my new sister, was just beginning.

Very good story coderider. It's nice to see that there are still some authors that still write long chapters, pay attention to the English language with proper grammar and spelling. I did notice one error in Chapter 2 where you used accept instead of except. But you know, I know I have errors in my story as well probably my biggest being redundancy. Anyways, I like the content of this story. It's another controlling story to an extent but it hasn't turned into a mass produced bdsm story on this site and even if it does start to go that direction you do have a unique situation and have incorporated the elements of truth and dare. It has a nice pace you're not moving too fast. Having said that keep up the good work and I look forward to future installments.

[Saphir]

I totally agree with Komodo
And I love the length of your chapters, when you update then it's not like only 2 Minutes reading and then waiting again.

Looking forward to more

[slutjuice]

I love this story! The attraction but knowing that it's wrong, the slowness, (some writers speed to the physical)and of course the length of chapters. Keep writing!

[coderider]

Thanks for the comments and feedback! I'm glad people are liking it.

[Saphir]

Damn I thought there was a new chapter! :P
