I first noticed my sister a little over a year ago, when she was in the seventh grade. I remember her coming up to me, and saying in her sweet, unintentionally arousing voice, “Hey, big brother, can I ask you something?”

“Sure,” I said, not quite sure what else to say. Me and my sister are pretty close. We’re not best friends or anything, but we talk about our lives to each other, and she sort of idolizes me.

“All of the boys at school are always talking about which girls are the hottest,” said Kelly. “And I have no idea if I’m hot, or ugly, or what. And I figure, you know, you wouldn’t lie to me. So, you know, am I, well, hot?”

I looked at my sister. Regardless of what she actually looked like, I would have said that she was very pretty. But I suddenly realized that she was actually quite attractive. Of course, at the time, I would never have admitted that I thought my thirteen-year-old sister was giving me a boner.

“Oh, yeah,” I said. “You know, I’m your brother, so-“

“What difference does that make? You’re still a guy, aren’t you?”

I laughed nervously at my sister’s stubbornness. “Yeah, you look pretty good for someone your age,” I said. “You’ll probably be really- really pretty when you get to high school.” I did not mention the fact that she already looked better than a lot of girls in my class.

“How about these?” asked Kelly. She pulled up her sweater and undid her bra to reveal her tits. They were already big (although still developing then). They were perfectly shaped. Her nipples were small and hard. My boner got even bigger.

“Yeah, Kelly, they’re really… nice,” I stuttered. “Listen, Kelly-“

“Are they big enough?” she said in an inquisitive tone of voice.

“Oh, Kelly, of course,” I said. “They’re perfect.”

Kelly giggled. “Do you want to touch them?”

“Kelly, listen, you’re my sister. We really shouldn’t be…”

Kelly giggled again and grabbed my arms, placing them on her firm tits. “Don’t be shy, big brother,” she said. “Feel your little sister’s tits.”

“They’re nice,” I said, pulling away. “Listen, Kelly, you’re my sister, and you’re four years younger than me. Just trust me, you’re a pretty girl. You don’t have to worry about anything.”

“Well, fine, then,” said Kelly. She picked up her bra and redid it, and then pulled her shirt back on. “I’ll see you later.” She sounded kind of annoyed.

“Kelly, listen, I…” I started, but she was already gone.

A year had passed since then. Kelly was now an eighth grader, and looked more amazing than ever. I was now an eighteen-year-old senior, and I was noticing my little sister more and more. I knew how wrong it would be to ever get with my sister, but since that day a year ago, I had been fantasizing about it more and more. I half-wished that I had done so a year ago. If I had offered to let my sister give me a blow job, I was sure that she would have complied. But I couldn’t do that. Because incest was wrong.

Right?

Part of the reason I was lusting after my sister was that at eighteen, I was still a virgin. I had made it to third base, but I was anxious to go the rest of the way. I also tended to find that I was into younger chicks. My last girlfriend had been a freshman, which a lot of my friends thought was kind of weird. I didn’t care that much, though. But Kelly was a whole different matter. She had just turned fourteen, and I was sure that she had never so much as given a blow job before. Plus, she was my sister.

But I could hardly stop thinking about her. I snatched bras from her dresser and jerked off in them. I watched her from the window every time she went into the hot tub. I gave her rides to all of her volleyball games just so I could see her in her Spandex.

One day, when I arrived home, Kelly was sitting on the couch. She had her head in her hands, and it looked like she had been crying.

“Kelly, what’s wrong?” I asked.

She took her beautiful head out of her hands, and stared up at me with those beautiful, knowing eyes. “Dave, no one’s asked me to the winter dance, and it’s in only three days. I think all the boys think that I’m ugly.”

“Don’t worry, you’re gorgeous,” I said, truthfully- at that moment, I was picturing her naked. “Guys will be all over you once you get to high school.”

“But I want to go to the dance,” she said. “And if I go by myself, I’ll look like a loser.”

I sighed deeply, and mustered all my courage. “Kelly, I can with you if you want me to. You know, we’re friends and whatever.”

Kelly’s face broke into a smile. “Really?”

I sighed again. “Yeah, sure,” I said.

Kelly hugged me, I pulled her away quickly so she wouldn’t feel my boner against her side. “You’re the best brother ever!” she said.

“I know,” I said, feeling the need to spend a long session in my room with only a certain C-cup to keep me company.

The night of the dance, I stood by the door, waiting for Kelly to come downstairs. I felt like a loser. It was 9:00 on a Friday night, and I was taking my little sister to a middle school dance. I had never wanted to go back to middle school dances after middle school. But there I was. I consoled myself with the fact that at least no one I knew would be there. I didn’t know any of Kelly’s friends or their parents.

“I’m ready,” called Kelly. She came towards me, and I was stunned. She looked completely grown up. She had a black, low-cut dress on that showed quite a bit, and her dress came only to her knees. Her hair was pulled elegantly into a bun.

“You look nice,” I stammered.

“You too,” she said sweetly. “Let’s go.”

On the drive over, Kelly turned down my music.

“Dave, I need to ask you… kind of a favor,” she said.

“What?” I asked reluctantly.

“It’s just this,” said Kelly. “I sort of told all my friends that you’re my boyfriend, not my brother. Because if I told them you were my brother, they’d all think that I was a loser. I told them you’re a senior at Creekwater High School. They were all really impressed. So if you could pretend that we were going out, I’d…”

I groaned. This would be bad enough if I wasn’t secretly strongly attracted to her. “I don’t know, Kelly…” I said.

Kelly gave me a cute, begging face. “Pretty please…”

I couldn’t refuse her. “Fine,” I said. “But next time you want me to go with you to a middle school dance, count me out.”

The two of us entered the school gym. We passed the teachers at the front, who gave me kind of strange looks, but I look kind of young, and they might have thought I was only two or three years older than my date, rather than four. They also almost certainly didn’t suspect that we were siblings. I felt like an idiot.

“What am I supposed to do?” I asked her.

“Just come with me,” she said. She grabbed my hand and pulled me over towards her friends. I was holding my hands with my sister. Was that sexual? Or was she just pulling me in the right direction? Well, maybe if I wasn’t pretending to be her boyfriend, I would have been less worried.

“This is my boyfriend, Dave,” said Kelly. “He’s a senior at Creekwater.”

“Hi,” I said. Two of Kelly’s friends blushed and giggled. They clearly thought that I was hot. I remember middle school well enough to know that.

The next hour was pretty boring. I just stood next to Kelly, holding her hand as she talked to her friends. I was about to ask her when we could get out of there when she announced that she had to use the bathroom and hurried off. I tried not to watch her tits bounce up and down as she left.

That left me with her friends. It was pretty awkward. I didn’t know what to say to them, and they didn’t know what to say to me. Finally, the boldest of them said to me:

“So you’re the Dave that Kelly is always talking about?”

I was mildly surprised. “She’s always talking about me?”

“Oh, yeah,” said Kelly’s friend. “She won’t shut up about you. She always mentions how hot you are, and how much she likes you.”

I wondered about this for a moment. Was Kelly actually attracted to me? No, she must just be bragging to impress her friends. That was it. An image of Kelly naked, begging for me to fuck her harder, filled my mind. I quickly pushed it away.

“So,” continued Kelly’s friend, “have you two done it yet?”

“What?” I asked, suddenly realizing what she was saying. “No! Nothing like that.”

“Really?” asked the friend. “I think that she wants you. You have no idea how many boys she turned down in our class to go with you. She turned down Duke Hawthorne! I would give anything to be with him.”

What? Kelly had turned down other boys to go with me? What was she doing? Was she honestly attracted to her? What would I do if she was? I couldn’t go with her. That wouldn’t be right. I was not going to fuck my fourteen-year-old sister. I couldn’t. I never would…

Kelly returned, but I didn’t have time to say anything to her. “This is my favorite song!” she shouted, as some poppy tune blared. “Let’s dance!” She pulled me out onto the middle of the floor.

She pressed her body up against mine as we danced. I smelled her strong perfume, and felt her hair in my face. She was smiling…seductively? I didn’t know.

“Kelly, what’s going on?” I asked. “Your friend told me that…”

“Shhh, we can talk about it later, Dave,” she said. She pressed my body even further up against me. I had a huge boner by now. As I looked into her sweet face, it became harder and harder to resist. She was everything I wanted in a girl, everything I had dreamed of for a whole year. But I couldn’t have her. I shouldn’t have her.

I looked into her beautiful blue eyes, and she looked into mine. And as the song ended, our mouths somehow moved together (I can’t say who initiated it), and we started kissing. Our tongues moved together, and intertwined. The kiss lasted for almost a minute. When we broke apart, I was staring at her, and she was staring at me. I think maybe there were other people looking at us, I don’t know, I don’t care.

“I want you,” I whispered.

Kelly silently grabbed my hand and pulled me out of the gym doors and into a small hallway. She pulled me into a classroom, turned on the light, and shut the door.

“This is Mr. Elmi’s old room,” she explained. “No one ever comes in-“ I didn’t wait for her to finish. I pressed my mouth against hers, and my body against hers, and we started to make out again. After a while I decided to get adventurous, and I started unbuttoning the back of her dress. As I did this, she reached into my pants and pulled my long, hard, eight-inch dick out of my pants. To make it easier for her, I unbuttoned and unzipped my pants, pulling them down. I then pulled her dress down and let her continue to finger my cock.

Our embrace broke briefly. “It’s huge,” she said.

“All because of you.”

I got my first real look at Kelly’s body, which was naked except her bra and underwear. She was very skinny, but not unhealthily so. There were some freckles across her skin, which was light but not pale.

Kelly giggled. “Like what you see, bro?”

“Sure do, little sis,” I said. “But let’s see your tits now.”

Kelly reached back and pulled off her bra. Her tits were much bigger than a year ago, and they looked succulent. They were round and perfectly shaped. I touched them, felt them, embraced them. I couldn’t hold myself back. As she continued to feel my cock, I rubbed, even licked her enormous tits.

Kelly bent into a kneeling position. “Get ready,” she told me. I didn’t need to get ready. I had been ready since that day a year ago, even if I didn’t know it then. Kelly began kissing the end of my cock, stroking it and eventually licking and sucking it. I watched with amazement as she put the entire thing in her mouth, sucking it back and forth. No girl I had ever been with before, not even the ones my age, had accomplished this in my life. I continued to play with her tits as she sucked my cock.

“Come on, little sis! Suck harder!” I half-shouted. “Yeah! Yes!” The cum started to come out, and she was ready. With a few gulps, it was almost all down. As I withdrew my dick, she licked off the last drops from around her lips.

“Wow,” I said. “That was the best blow job I’ve ever had.”

“It was the biggest dick I’ve ever had,” said Kelly.

“I can’t believe we just did this,” I admitted.

“I can,” said Kelly. “I’ve dreamed about it for so long.”

“So have I, I guess,” I said, smiling. “So in your fantasy, what happens next?”

Kelly shrugged, sounding kind of embarrassed. “Well, I have this thing- well, I don’t know what you’d call it- but thinking about it really gets me horny- well, you know…”

“What is it?” I asked.

“You’re sure you won’t think it’s stupid?”

“Listen, I just took my fourteen-year old sister to a middle school dance, pretended to be her boyfriend, and ended up making out with her and getting a blow job from her,” I said. “I don’t think I can judge.”

“I just really like being spanked,” she said.

I smiled. “Just pull your underwear down.” She did so, revealing her nice ass and tight, shaved pussy.

“And let your hair down.” She complied, letting her beautiful, wavy blonde hair fall down around her shoulders. I added my shirt to the pile of clothes now lying on the floor.

I reached out and smacked her in the behind with my palm. She let out a sound halfway between a moan and a scream.

“You’re a bad little sister,” I yelled. “You’re a naughty, naughty, little girl.” I could tell that she was getting turned on. As I smacked her, she would scream, or shout.

“Oh, yeah! Oh, yes!”

“You’re a bad, naughty little girl, aren’t you?”

“Yes! YES!”

“You need to be punished!”

“Oh, YES! Come on!”

“You’re a bad little sister, aren’t you?”

“Yes, big brother! Yes!”

I turned around, and faced her. She was sweaty and her long hair was in her face. I must have been about the same. We were both unbelievably turned on. I grabbed Kelly and pushed her onto one of the tables in the classroom. “You ready?” I asked.

“Oh, God, yes!”

I shoved my dick into her unbelievably tight pussy and penetrated her hymen, taking her virginity. She screamed.

“Are you okay?”

“I’m fine,” she panted. “Just FUCK ME!”

I decided to do as she said, pushing back and forth as she screamed with pleasure.

“Kelly…Kelly!” I shouted. She screamed back. A pile of books that had been on the table were pushed off by her wild thrashing. She was absolutely out of control, and so was I.

“DAVE…DAVE!” Her tits bounced around, and her hips gyrated as I fucked her ferociously. There was a look of rapture on her face as she took it, yelling with pleasure. I was briefly worried about someone at the dance hearing, but it was way past eleven by now, and everyone was gone. I pushed in and out, and it was the best feeling I have ever felt. I couldn’t believe that after years of dreaming, I had finally taken my little sister’s virginity.

“OH, GOD, DAVE, HARDER!”

“Kelly…” And then her pussy became tighter and wetter…

“Bro…Dave…”

“Sis…”

And then we orgasmed spontaneously. It was perfect. Streams of cum pulsed from my dick into her pussy.

I pulled my dick out of her, and the two of us just laid there, panting for breath. I couldn’t believe what I had just done. I had fucked my little sister. What if someone found out? I glanced over at her. Her long, blonde hair still hung behind her head. She was looking at me with impressed satisfaction.

“I always knew you… wanted me,” she said, still struggling for breath. “We just needed the… the right situation.” She reached over and kissed me on the lips.

“You were incredible,” I said.

Kelly blushed a little. “Thanks. It was pretty amazing. We should probably get home soon. I’m sure Mom and Dad are freaking out.”

I laughed. “Yeah. I don’t think we should tell them what really happened.”

Slowly, we began to gather up our clothes. I helped Kelly put her dress back on and then put my own clothes on. We drove home together and didn’t say much the entire time. Not much needed to be said.

As we arrived home, my dad was standing there. “What took you two so long?” he asked. “It’s almost 12:30.”

I smiled. “Sorry, Dad, the car wouldn’t start.”

“Well, you’re an hour and a half late,” he snapped. “I hope you have better luck getting the car to start next time.”

“Actually,” whispered Kelly to me, “I think the car’s going to have quite a few problems in the next couple of weeks.”
