"So... how do we start, Jace?" asked my twelve-year-old sister, Danna, as we stood there in her bedroom together.
"I don't know for sure," I admitted. I was only fifteen myself and wasn't really prepared for this.
It was really a kind of bizarre situation anyhow. My sister and I had been hanging out together downstairs, playing a video game and chatting as the rain poured out of the dark summer skies.
Somehow we'd gotten onto the topic of sex. I don't really remember who first brought it up, but we did talk about it. We both were virgins, neither of us had done more than kissing with someone of the opposite sex and, as we talked, we learned that both of us masturbated.
This brought us onto the inevitable questions from me about how girls did it and from her about how boys did it. I found her descriptions interesting, but they didn't make all that much sense to me, and I was pretty sure she was thinking much the same thing.
So it was that Danna finally brought up the idea of the two of us masturbating in front of each other so that we'd both learn how boys and girls did it. I tossed the idea around in my head and found that I liked it. Now we were both in her bedroom trying to figure out the best way to get started.
"I guess we should probably get undressed," I finally said.
Danna nodded. "Like all the way naked, do you think? Or like we just unzip?"
"Well, if we just unzipped, would you be able to do anything?"
"No," she admitted. "I guess we should get all the way naked, then."
"Ok," I said with a nod. "So do you wanna go first or should I?"
"How about we go together?" my sister said after a moment.
I was very nervous as I started undressing in front of Danna. The only thing that kept me going was the fact that she was probably just as nervous as me. Well, that plus the fact that I'd get to see a naked girl.
As soon as all my clothes were off I stood up straight, letting my sister see my naked fifteen-year-old body, the first time I'd ever been naked in front of anyone else. I wasn't much, I guessed. I didn't work out, I was kind of pale, very scrawny. I had a nice penis, though, I thought. It was about six inches long and very straight.
And as my sister stood up, giving me my first ever view of a real life naked girl, my penis gave a little twitch. She was only twelve, so it wasn't like she was some sex goddess or anything, but she did look nice. Her breasts were still small, but noticeable, she had smooth skin, a thin waist, and just a little hair between her legs. She was certainly one of the most beautiful sights I'd ever seen!
"You look nice," I offered.
"So do you," she replied.
"So... I guess we just sit down and get started?"
"Ok. Let's sit on my bed."
Feeling a little shy and embarrassed I sat down at the foot of my sister's bed while she sat up at the other side. We sat there and sort of checked each other out for a little bit. Then Danna said, "So should we get started?"
As I reached down and took hold of my erect penis, stroking it slowly, my sister spread her legs, giving me my first view of a girl's vagina. She put her hand down there and started rubbing all over, moving in a slow, steady rhythm not unlike mine.
"That looks cool," she said, looking at me.
"Yeah... you look cool, too." It wasn't the most scintillating dialogue, but it was true.
Mostly my sister ran her fingers along the sides of her vagina and around a little knob at the top (her clit, I guessed). But as we kept masturbating, I watched my sister press a finger against her vagina and then to amazement, slip it up inside. I experienced a surge of pleasure seeing that. She had her finger inside her vagina! That's where a boy's penis was supposed to go! My pulse quickened.
"Are you enjoying this?" Danna asked.
"Yeah. Are you?"
After a few more minutes of watching each other masturbate, I said, "Uh... Danna?"
"Do you have... an old sock... or some Kleenex... or something?"
"What? I think so. Why?"
"Because... because... I... ooh.... oooooh!" My whole body shook as the most intense orgasm of my life hit me. The sperm blasted out of my penis at barely subsonic speed and ended up all over my nude body.
My sister looked at all this with wide eyes, one hand still holding the sock she'd picked up off the floor. She opened and closed her mouth a couple times and then said, "Well... I guess that answers that question."
"Sorry!" I gasped out.
"Is that... sperm?" she asked.
"Yeah." I took the sock from her hand and wiped my cum. "Sorry again."
"That's ok, Jace." My sister leaned back and started playing with herself again. "I'm gonna finish up real quick."
I sat back and watched my sister as she slipped a finger back into her vagina and finished masturbating. It was really interesting! Her body shook a lot like mine had when her orgasm hit. She got this really wonderful look on her face. It was pretty obvious that it felt wonderful!
"Wow, that was hot," I said with a grin.
"Thanks..." she said, smiling a tired smile of her own. She pulled her finger out of her vagina. It was all wet and slick. "We better get dressed," she said, as she reached for her clothes.
We dressed in silence, both of us a little weirded out by what we'd just done. At least I was a little weirded out. I wasn't sure what Danna thought. Once we were dressed we both walked out of her bedroom and downstairs.
"I had fun, Jace," Danna said after a bit.
"Really?" I grinned. "Me, too."
"Maybe we can do it again sometime?" she asked shyly.
Danna and I didn't really say much to each other for the rest of the day. We just went about our normal lives, ate dinner when our parents came home, watched some TV and eventually went to bed. Before I fell asleep I, of course, masturbated. And when I did so the only thought in my mind was Danna.
* * *
The next day I didn't see too much of Danna until the early afternoon. She'd gone out and done some stuff earlier in the day. But finally she came back and, after going up to her room and dropping off her things, came in and sat down next to me on the couch.
"Anything good on?"
We watched something stupid in silence for about twenty minutes. Then Danna said, "Jace?"
"I had fun yesterday. You know. With what we did?"
"Yeah, me too."
She was quiet a little longer and then said, "Jace?"
"You wanna do it again?"
"Sure!" I said, and then tried to reign in my enthusiasm. "I mean, if you want to."
"Well, it might be fun," she said.
"More fun than doing it by ourselves, anyway."
"That's for sure."
"So you want to?"
Quietly my sister and I walked up to her bedroom. Once there, she shut the door and without saying anything we started getting undressed. As soon as we were both naked we sat back down on her bed and started fondling ourselves again.
"You know, it's really cool we can do this together," I said.
"Yeah. I've always wondered about how boys do it."
We masturbated quietly for a few moments and then Danna said, "What does it feel like?"
"Uh... well, it feels good, of course."
"No, I mean, what does... you know... your penis feel like?"
"Oh!" Now I got it. "Uh...well, its smooth, and kind of hard and soft at the same time. And it's pretty warm."
"What does your vagina feel like?" I asked, my eyes locked onto the item in question.
"Well... it's kind of wet and when I have my finger inside, it's even more wet and very warm and tight."
"Cool," I breathed as the pleasure built up inside me.
"Oh, god," I whispered. "Here I go again..."
This time my sister was much faster. She whipped out a washcloth from under her pillow and tossed it to me just as the first burst of sperm shot from the end of my penis. I let out a series of low, moaning gasps as I spurted into the cloth.
As I finished cumming, my sister started, moaning and groaning a little as her hands moved in a blur, riding her orgasm to the finish and obviously enjoying every single moment of the experience.
After we were done cumming, Denna giggled. "You look so cute when you do that."
I laughed, feeling none of the post orgasmic tension that had come up last time we had done this. "Yeah, well, you do, too."
Neither my sister nor myself made any more at all to sit up or get dressed. I held the washcloth in my hand, not sure what I should be doing right then. We just sort of sat there for a few moments, looking at each other's naked bodies.
During this time I was really aware of everything. I could smell the scent of my sister and her bedroom. I could hear the faint rustle of her posters as the A/C blew them around. I could feel my heart beating fast. I didn't know what I wanted to do right now, but I knew I didn't want this moment to end.
"You have a really nice room," I finally said, for lack of anything better to say.
"Thanks. I like it."
"You got a nicer bed than me, too."
My sister laughed. "Thanks!"
As we sat there, and I looked more at my sister's naked body, especially since her legs were still somewhat parted, my penis started to get hard again. Danna noticed this and laughed a little.
"You're ready to do it again?"
I laughed. "I'm sorry. You're just having an effect on me." I made no move to cover up and she did nothing to suggest that I should.
"I do?" she asked shyly.
"Well, yes. You're cute," I mumbled.
My sister got up onto her knees and struck a pose. "Gorgeous!" she said in a sultry voice.
I laughed. "Oh, yes! Supersexy!" I got up onto my own knees and struck a manly pose.
We both dissolved into helpless giggles at how silly we were being and fell back onto my sister's bed where I smacked my head on the wall.
"Ow! Damnit!" I called out, sitting up and rubbing the back of my head.
Danna laughed. "Watch out there! Your head is so hard it my break my wall!"
I stuck my tongue out at her, and then wiggled my erect penis. "It's not the only thing that's hard."
Danna giggled again. "Yeah, I can see that, Jace."
Licking my lips, I said, "Well... if you want... we can do it again?"
"Do you want to?" she asked.
"Only if you do."
"Well, I do if you do."
I laughed. "Ok! I do!"
My sister and I sat back to watch each other as we started to masturbate again. It was almost feeling routine, I realized. After all, this was going to be the third time we'd see each other play with ourselves.
"Danna?" I asked after a few moments.
"Do you wanna..." I licked my lips. "Do you wanna try... touching each other? Just to see what we each feel like," I added quickly.
Danna considered this for a second. "Well... I guess it's ok. I mean, we're just playing around, right, so it's not like it's a big deal?"
"Ok. I guess we can touch each other, then. I mean, I am curious about it."
Neither of us moved even an inch towards the other.
"So... how do you wanna do this?" my sister asked.
"Uh... well, ok. I got an idea. Why don't you lay on your back and spread your legs? I'll go first and then you can touch me."
My sister did as I suggested and I moved closer, almost laying on my stomach between her legs as I got my face about six inches from her vagina. It was the most incredible thing I'd ever seen! It looked vaguely like some strange, tropical flower.
I placed my fingers above my sister's vagina and ran them slowly through the hair, down across her clitoris and onto the folds of her labia. The textures felt soooo cool under my fingers! Everything was so warm and so wet!
My questing fingers soon found the one spot that was especially warm and wet, and the tip of my finger sank inside a little. No doubt what this was. Very gently I pushed my finger forward, watching as it slowly sank into my preteen sister's tight, warm, wet, virgin vagina. Magnificent!
"Oooooh..." Danna whispered as her body tensed. "Oh, Jace... oh, that feels nice..."
Remembering how my sister had moved her finger inside her vagina, I started doing the same, slipping it back and forth, basically fucking her with it and really enjoying myself! Then I got an even better idea and started using my other hand to play with the area around her clitoris, again trying to do to her what I'd seen her do to herself.
"Oh, Jace..." Danna moaned. "Oh, don't stop..."
I continued playing around with my sister's vagina, wondering if she was going to wind up having an orgasm because of what I was doing. I really hoped that she would! The idea of making her cum was REALLY cool!
Turned out my instincts were right! My sister started moaning loudly, and her vagina began contracting hard around my finger as she began shaking and twitching. Having seen her cum twice before, I knew exactly what was going on, and felt more than a little pride at the fact that I'd given my own sister an orgasm!
I sat back and grinned at Danna as she tried to recover. "So, am I good, or am I good?"
"No!" she gasped. "You were great!"
I grinned. "Excellent."
"So," she said after a moment. "I think it's my turn now."
"Ok." Trembling with excitement and antici...
...pation, I leaned back on my sister's bed. She sort of crawled towards me and without any real hesitation put her hand around my erect penis. I let out a little gasp at the contact. No one but me had ever touched it before! This was soooo cool!
Then she started slowly moving her hand up and down the length of my penis, all the way from the tip to the base. It was all I could do to hold still and not wind up cumming after the first three seconds.
"Am I doing it ok?"
"Oh, god, yes," I whispered. "Go faster..."
At this point I was VERY grateful that I'd already cum earlier, cause if I hadn't, I would have been spraying everywhere. As it was, it was only a matter of a few minutes before I gasped out, "Oh, god, Danna, I'm cumming!" and felt my brain offline as my penis kicked and spurted in my sister's hand, my sperm flying out all over my body and hers. To say that it was the best orgasm of my life was to seriously understate things.
My sister was looking at me with a vaguely stunned expression on her face.
"Wow," she said. "THAT was interesting."
"Yeah..." I said, breathlessly.
She looked at the white gooey mess on her fingers. "So this is sperm?" She sniffed it. "Smells salty."
Danna regarded her fingers some more, then gave a little shrug and put her hand between her legs. Before my startled eyes she slipped her sperm-covered fingers into her vagina and moved them around a little bit before pulling them out, now free of the white fluid.
My sister grinned. "There."
My eyes widened. "You shouldn't have done that," I protested. "You might get pregnant."
Danna shook her head. "There's not enough of it for that, I don't think." She swirled her finger around in the small puddle of sperm on my stomach and then stuck it back inside her vagina. "Besides, this feels cool."
Before Danna could get anymore ideas, I grabbed the washcloth and wiped up what remained of my sperm, trying not to think about how erotic it was that some of my sperm was inside my sister's vagina.
"This was fun," I said as I stood up. "You wanna do it again tomorrow?"
Just as I was about to reach for my clothes, Danna stood up and put her arms around me, pulling me close in a very warm, very cozy, very affectionate and above all very NAKED sibling hug. My penis jumped as I touched her nude body against mine.
"I'm happy I have a brother like you. Otherwise I probably wouldn't have done anything like this for a long time."
"I'm happy I have a sister like you, too," I said with a grin. "And for the same reason."
My sister giggled. We both got dressed and went about the rest of our day.
* * *
The next morning I woke up to the strangest dream. In my dream there was a small aardvark who was whispering things into my ear and masturbating me. When I woke up completely, I saw that it wasn't entirely a dream. My sister was sitting, naked, on the edge of my bed toying with my erect penis through the sheet that was covering me.
"Good morning, Jace!" she said, sweetly.
"Hey, Danna," I said, wiping my eyes. "What's up?"
"Well, I thought we'd start our morning right." She grinned. "Plus I thought it would be cool to play around in your bedroom for a change instead of mine."
I chuckled sleepily, but waking up rapidly. "Sounds good."
I did and my sister got into bed next to me, snuggling up to me and taking my penis in her hand, stroking it slowly. In response I put a hand between her legs and worked a finger up into her vagina, moving it around as she masturbated me.
It was strange, I thought, that I was doing this stuff with my own sister. I knew it was wrong. It had to be. It was basically incest after all. Danna could call it "playing around" all she wanted, but I knew it was more than that. Not that I minded, you understand. I hadn't been joking last night when I said that if I wasn't doing it with her, it wouldn't have been likely to happen at all for me. At least not anytime soon.
"Stop for a second and lay on your back. Spread your legs."
I tossed the thin sheet off our naked bodies and looked down at my sister as I crouched between her legs. It was a wonderful sight!
Licking my lips, I said, "I wanna try something, ok, Danna? If you don't like it, tell me to stop, alright?"
"What are you going to try?" she asked, sounding tense.
"Are you going to put your penis in me?" Her voice was barely above a whisper.
Startled at the question, I said, "No. I have something else in mind."
I moved my face down towards Danna's vagina. Reaching out with my fingers, I played with her clitoris a little before slipping my index finger into her. All well and good so far, and from the noises, she was liking it. I hoped she liked my next plan as much.
Taking a deep breath, I stuck out my tongue and licked it along my sister's clitoris, eliciting a surprised gasp from her. Then I really went wild, licking everything that I could, even sticking my tongue as deep into her vagina as I could get it. I wanted to make sure she REALLY enjoyed this.
Judging from the way she was quivering on my bed and clutching at the back of my head, I must've been doing something right. She started moaning my name as I continued, which left no doubt in my mind that I was having a good effect.
Finally Danna said, "Oh... Jace... stop, ok?"
I lifted my face up from between her legs. "Ok... why?"
"It feels... too good..."
I actually sort of understood that. I nodded and moved my body up so that I was laying on top of her. "I'm glad I made you feel good."
"Oh, yes, you did."
Reaching down between our bodies, I took my penis and laid it against my sister's vagina. I was doing it because I wanted to keep laying on top of her like this, cause that felt good, but I didn't want to take a chance on accidentally slipping it inside her.
Danna apparently mistook my intentions. "Are you going to put your penis in me now, Jace?"
That was the second time in the last few minutes my sister had asked me that question. As my mouth went dry I moved my hand away from my penis and managed to say, "Do... do you want me to?"
"Yes." Very certain. Very matter-of-fact.
Seemingly of it's own accord, my hand moved back down and took hold of my penis. I rubbed the tip up and down along my sister's vagina.
"Are you sure?" I asked in a quiet voice.
"Yes... but if it hurts, you have to stop, ok?"
All thoughts that this was my sister and that this was horribly wrong melted away under the blowtorch from my hormones. I lined up for penetration and pushed forward just slightly with my hips, feeling a wonderful warm wetness around the tip of my penis.
I swallowed hard. Knowing that my sister was a virgin, I wanted to make her first fuck as wonderful and painless as I could. But since I was still a virgin myself, I wasn't sure how to do this. I figured it would be best if I just slipped into her slowly and waited to see what happened.
So that was what I did. I pushed forward very slowly, and very gently, and gradually, inch-by-inch, worked my fifteen-year-old virgin penis into my little sister's twelve-year-old virgin vagina, keeping an eye on her face as I did so. When I finally stopped I was all the way inside her.
"Oh, god, Jace..." were my sister's first words as a non-virgin.
"Yeah..." was mine.
"Fuck me..." she whispered.
Far be it from me to turn down a request like that! I began slowly moving back and forth inside my sister, feeling the wonderful clingy texture of her vagina around my teenage penis. It was far better than ANYTHING! Even better than when she'd made me cum last night.
Looking down between our nude bodies, I could see where my penis disappeared up into my sister's preteen vagina. As I pulled back, I saw the shaft, all wet and shiny, and then when I pushed back in all that I could see was my pubic hair crushed against her almost bare pubes.
"This is so nice..." Danna whispered. She smiled at me. "I can't believe... I'm getting fucked... by my brother..."
I grinned back and kept thrusting slowly. "I can't believe... I'm fucking... my sister..."
I laid my head down on her shoulder after that, feeling her small breasts against my bare chest as I fucked her with greater speed. I knew that when I came the smart thing to do would be to pull out, but I also knew there was no way I could make myself do that. I'd end up just having to cum inside her and hope she didn't get pregnant.
"Uh... uh... yeah...?"
"When you cum... cum inside me..."
That was it. Now I couldn't hold back any longer. My body tensed, I drove my penis as deep into Danna's vagina as I could get and let out a series of gasps as my orgasm hit and hit hard. I never came so much in my life! I shot so much sperm into her vagina, I was thinking she'd be leaking for a week! Oh, GOD it was amazing! What was really weird was that there was one part of me that really hoped I'd get her pregnant.
"Oh, Jace," my sister whispered as I laid on top of her, my penis still in her vagina as I tried to get my breath back. "Oh, Jace..."
From that day on the barrier was broken. My sister and I spent all our spare time having sex with each other. We fucked in every position we could, at least two or three times a day, and in every room of the house, including fucking in our parents bed on several occasions. There was something really kinky about that.
Unfortunately, it wasn't long before my sister and I became parents ourselves. We hadn't given any real thought to birth control. I think there was an unwritten desire between us to have a baby. Our parents were not happy when they found out Danna was pregnant, and even less happy when they found out I was the father. There was a lot of fighting, a lot of threats and lots of punishment. In the end, though, it didn't matter. She was pregnant, and that was that.
We ended up with twins, a son and a daughter, born just before my sixteenth birthday. We hadn't gone to any trouble to conceal who the father was. My friends were all shocked, as were other people we hung out with. Strangely the authorities didn't really bother us about it, which was good.
My sister and I kept up our affair after our children were born. We certainly didn't stop fucking. In fact, we had another child three years later, a son. After she turned eighteen, we took our kids and moved to another town, where we pretend to be married. We've talked about having another child and probably will.
We're deeply in love with each other, and as far as we're concerned it's no one's business if we're brother and sister. It started as just playing around, but now we're in love. And as long as there's love, that's all that matters.
