Up the Creek
Alex Hawk

“This is the spot, Matt! Right here!” called out my sister Cindy. She was twelve, a year younger than my thirteen years.

“Alright!” I said, following her over a small hill. We’d been walking for about thirty minutes, exploring the land our family had bought a few weeks ago. We’d moved out here to the midWest after spending most of our lives in Seattle, and it was really neat having all this land to explore! Since it was summer vacation we’d have plenty of time to look around and see our property.

“See! Right here!” she said, pointing to a small creek. We’d known it was somewhere on the land, but we hadn’t known exactly where.

“Oh, yeah!” I said, coming down the slope to join her. “Hey, cool. I wonder if there’s any fish in here?”

“Maybe. I saw a turtle down here earlier.”

“A turtle? Cool!”

We walked along the creek, looking into the water to see if we could spot anything of interest, but there didn’t seem to be much there. It was still pretty cool to see that we had our own little river here on our land!

Cindy and I paused under a large tree of some sort. I didn’t know what kind of tree it was. We were used to evergreens and anything beyond that was just outside our purview. It was big and shady, though, and that was what mattered, cause it was getting kind of warm.

I took a sip from the bottle of water I was carrying with me and leaned back against the tree. It was very nice outside.

“I like it here,” Cindy said.

I laughed a little. “I was thinking something like that myself.”

“It’s nice.”


Cindy looked at the creek. “I wanna go wading. I don’t think it’s deep enough to swim, but I think I can at least splash around a little.”

“That sounds like a good idea.”

My sister was wearing her jeans. She tried pulling up the legs, but they were really tight. Looking over at me, she said, “I’m going to take them off and go in my panties. Do you care?”

“Not really,” I said.

“Ok.” Cindy stood up and unbuttoned and unzipped her jeans, wiggling until they were off her, leaving her in a pair of light blue panties. She set her jeans aside and waded out into the water.

“Oooh! It’s kinda nice in here!” She said, walking back and forth.

“It is?” I asked.

“Yeah. Nice and cool.”

I was becoming aware of how hot I was. After watching Cindy splash around for a bit, I said, “I’m going to come in, too.”


My jeans weren’t quite as tight as my sister’s, but I didn’t feel like wearing them. I got out of them and my t-shirt and waded into the water in my boxers. As I got out into the middle of the water, I let out a happy little sigh.

“You’re right, Cindy. This IS nice.”

“See, I told you.”


I wanted to just lower my whole body into the water, but that would have left me with wet boxers, and I didn’t want to deal with that all day long, so I just suffered. Cindy seemed to be having the same thoughts. A couple times I saw her start to sit down in the water, but stop herself when she realized she was going to get wet.

Finally after too much of this nonsense, I said to my sister, “Look. You wanna splash around full-on, right, but not get your clothes wet?”

“Yeah, how did you know?”

“Because I wanna do the same thing,” I said with a little smile.

Cindy giggled. “Ok. So what do you wanna do about it, Matt?”

“Well… you know what skinny-dipping is, right?”

“That’s where you swim naked?”

“Yeah. We can maybe do that.”

Cindy seemed to consider this for a bit. “I don’t know… I guess it might be ok. We’ve seen each other naked before, after all.”

I dimly remembered us seeing each other naked like four or five years ago. I was surprised she remembered it at all. “Well, yeah. I mean, it’s been a long time, but it’s not any big thing, right?”

“Yeah, I guess…”

“So, you wanna try it?”

“Yeah… ok, I guess it’s ok.”

“Cool.” I stood up and got out of my boxers, tossing them onto the shore. Now naked, and somewhat aware of my sister looking at my body, I settled down into the water, hissing a little as the cold came into contact with my virgin penis, but then relaxing. It felt really nice.

As I got comfortable, Cindy took off her shirt and her panties. I found myself looking idly at her as she stripped. Really all that I was thinking about when I came up with this idea was how nice it would be to get really wet. I had no sexual thoughts whatsoever about Cindy. Why would I? She was my sister, after all. But now as I looked at her naked body, I realized I was getting a major hard-on.

It was a nice body to be sure. Her breasts were still pretty small, but very nice, and she had only a couple strands of hair between her legs. I could see a beautiful little slit other than that. It was very cool seeing her like this, and it did make me horny, I’ll admit. I figured the thoughts would go away soon enough, though.

Cindy sat down in the water across from me. I saw her nipples harden as the cold hit her. She sucked in a breath, but then soon relaxed.

“Oh, this is very nice, Matt. What a good idea!”

“Thanks,” I said. “I like it.”

Cindy grinned an innocent grin and suddenly moved her arm, sending a nice splash of water directly into my face.

I sputtered and spit out water. “What the hell was THAT for!”

“Because, dummy, that’s what you do in water like this.”

“Says who?” I asked, moving my arm slowly.

“Says- ACK!” she cried out as a wave of water hit her right in the face. “You dork!” Cindy said, and launched herself at me.

Giggling and splashing, we fell together into the water, wrestling around under the surface, trying to dunk each other and just generally having a good time of it. The entire time my penis was very hard, but I didn’t really pay any attention to it, figuring that it would calm down and behave itself in time.

Meantime there was the wrestling to concentrate on! At one point Cindy managed to get me onto my back and dunked my head under the water while straddling my waist. I wasn’t about to put up with this and quickly flipped her over. With a little squeak she fell onto her back. I quickly laid on top of her, holding her down with my body positioned between her legs.

“Say uncle!” I said.

“Never!” Cindy replied. She sucked in a bit of water and sprayed it out at me.

“Oh, gross!” I said, and started moving around, trying to get a hold on her so that she couldn’t move. Cindy fought back, and as we moved I started to become aware of the tip of my penis pressing against something very warm. I was still an ignorant virgin and made no connection at all.

Still giggling, Cindy shifted her body under me and I shifted mine on top of hers. Suddenly I the felt the strangest sensation of my penis pushing into a very soft, warm, tight, yielding place unlike any I’d ever been in before. Reflexively, I pushed forward until I was completely inside, wondering just what the hell was happening. Whatever it was, it was certainly incredible!

Then I looked down at Cindy’s wide-eyed face. She had the strangest look of shock, surprise, confusion and pleasure. I couldn’t really describe it any more than that. It wasn’t anything I’d ever seen before.

That was when I made the connection. I looked down, but I couldn’t see anything clearly under the water because my body was in the way. So I pulled back a little with my hips and then pushed forward, experiencing the most incredible pleasure I’d ever felt in my life. Cindy let out a little whimper in response and I suddenly knew what had happened.

Somehow during the wrestling and fun, my thirteen-year-old virgin penis had wound up positioned just perfectly to enter my little sister’s twelve-year-old virgin vagina. When we’d moved around, well… so now I was actually inside her! Oh, god, it felt wonderful! Then my brain kicked in about just how wrong the situation was.

Quickly I pulled back, feeling a shock of cold water on my penis as it withdrew from Cindy’s vagina. I sat down hard on the bottom of the creek and stared at my sister, trying to get my breath back. She sat up a little and looked back at me.

Feeling that I had to say something first, I began with, “I’m really sorry, Cindy! I didn’t mean for that to happen! Please don’t be mad!”

“Were you just… were we… did you…” She didn’t seem to be able to really think right now.

“I’m sorry, I’m sorry! I didn’t mean for it to happen!” I was getting on the verge of panic right now.

Cindy stood up and quickly walked over to shore, grabbing her clothes and putting them on. I got out and started getting dressed, too. She began walking fast back towards the house and I had to really MOVE to keep up with her, constantly apologizing as we walked, and getting more and more worried as she ignored me.

When we were about halfway to the house, Cindy stopped and turned towards me.

“Just to make sure… I mean, I’ve never done anything like… well… I mean… you did have… you know… your dick… in me, right Matt?”

I hung my head. “Yeah… I didn’t mean to… I’m sorry…” I felt like shit and I could tell I was probably going to start crying soon.

“So you were… fucking me…” she said softly.

“I’m really sorry,” I choked out.

Cindy softened a little. “Look, Matt, I know it was an accident… I’m just… I don’t know… I know you didn’t mean to do it, though. I’m not mad at you.”

“You’re not?”


“I didn’t meant to hurt you,” I said, trying to hold back the tears.

Cindy shook her head. “You didn’t hurt me. It actually felt really good. I just… well, I hadn’t expected it, you know?”

“I didn’t expect it, either.”

“I’m sorry I got all mad at you.”

“It’s ok… I’m sorry I accidentally fucked you…” I said with a little smile.

Cindy smiled back a little. “Look… don’t tell Mom or Dad about this, ok?”

I laughed a ragged laugh. “I wasn’t planning to, Cindy, believe me. You won’t tell either, right?”



Cindy held out her hand and we shook on it. Then she said, “We should probably get back home.”

“Yeah, ok.”

Cindy surprised me by giving me a very tight hug and when we broke it, we started walking back to the house.

All through the day I kept feeling really weird about what had happened. I felt very bad about it and very guilty about it, and even worse about the fact that it felt so good to be inside my sister’s vagina and then even worse than THAT when I kept getting hard every time I looked at her.

Late that night when I was in my bed trying to sleep, my erection kept distracting me. Finally I realized that I would never sleep without jerking off. Of course when I did so, I kept thinking about how fantastic it had been to have my penis inside my sister’s vagina. I came buckets thinking about fucking her and then slept fitfully, consumed by guilt and very confused about everything.

* * *

Next morning after I woke up, I started masturbating again, thinking about how I’d basically fucked my little sister. I wound up cumming all over myself and felt very guilty about it. I was so confused, really. I mean, it had felt good and all, but I knew it was bad. I just didn’t know what to do, what to think or what to feel. It was driving me nuts.

When I went downstairs for breakfast, Cindy was already sitting at the table eating some cereal. I thought about just sneaking back up, but she saw me.

“Hey, Matt.”

“Hey.” I walked over and got some cereal, sitting down at the breakfast table with Cindy.

We ate in awkward silence for a while. I kept wondering what was going through her mind. What she felt about yesterday. If she was mad, if she was indifferent. I also kept thinking about how she’d mentioned that it felt good having me inside her. That thought made me nice and hard.

Finally Cindy said, “Look. We need to talk about yesterday.”

“I was just thinking that.”

She was quiet for a little longer and then said, “Do you think… did that count as… you know… sex?”

I picked at my food. “I don’t know. I mean… I had it in you and everything… but… I don’t know if it counts or not.”

Cindy nodded. “I don’t know either. I mean, I know sex is where, you know, a guy has his… well, his penis inside a girl… and you had yours in me… but…” She trailed off and shrugged.

“Yeah. I don’t know. I wish there was someone we could talk with.”

“Yeah. But you won’t be telling anyone, will you?”

“No. Will you?”

“No.” She ate a couple more bites of cereal and then said, “So what happens now?”

“With us?”


I sighed. “I don’t know,” I confessed. “I kept thinking about it all last night.”

“You did?”


“Me, too. What did you think?”

I shrugged. “I don’t know. I thought about a lot of things. What did YOU think about?”

Cindy shrugged back at me. “Lots of stuff. Mostly just that I hoped you weren’t, like, mad at me or anything.”

“Mad?” I echoed. “Why would I be mad?”

“I don’t know. Just because.”

Laughing a little I said, “Sounds like we’re both kind of confused about it all.”

“Yeah.” Cindy smiled a little and I felt some of the tension go away.

“Can I ask you a question?” I said as she stood and started clearing her dishes from the table.


“Well… you said that, you know, it felt kind of good when I was in you?”

Cindy shook her head. “No. I didn’t say that.”

I blinked. “You didn’t?”

“No.” She grinned a little. “I said it felt REALLY good when you were in me.”

I laughed again and started clearing away my dishes. “Ok, ok. You’re right, that’s what you said.”

“So what was your question?”

“Well… did it feel good for you?”

“Yeah,” she said with a nod as I began rinsing my dishes. “I mean I was a little shocked at first, but then it felt very nice.”


“What did it feel like for you?”

I looked directly into Cindy’s eyes. “It was the best thing I’d ever felt in my life.”

Cindy blushed a little. “Really?”



We walked into the living room together. Cindy quietly said, “Can I tell you something, Matt?”


“Last night when I was in bed I was… well, touching myself… and I kept thinking about you… and how it had felt when you were inside me…”

“You did?”


I smiled a little. “I did the same thing.”



“Cool!” Cindy giggled.

“I wish we knew if it counted as sex,” I said.

Cindy said, “I know… well, let’s figure it out. What exactly is sex?”

“Don’t you know?” I asked, briefly confused.

Cindy rolled her eyes. “Of course I know, Matt. I want to hear you give me a definition.”

“Sex is when a boy has his penis inside a girl’s vagina,” I said. Using the real words made me sound a little more knowing than I actually was.

“Ok, so you had your penis inside my vagina, but you took it out really quick.”

“Yeah… I think you also have to, like, actually move it in and out for it to count as sex.” The conversation was giving me a massive hard-on.

“I felt you moving it a little,” Cindy said.

I nodded. “Yeah. I moved it in and out once cause I wasn’t sure where I was or what I was doing. I figured moving might tell me.”

“Did it?”

“Yeah. When I saw your face it was pretty easy to put two and two together.”

“Ok. So you moved it in and out once. Does that count as sex?”

“It might,” I said with a shrug. “I think also for it to be sex maybe the boy has to shoot his sperm into the girl?”

“You didn’t do that, did you?”

“No, I wasn’t even close to doing that.”

Cindy thought about this. “No… that doesn’t work because you had your penis inside my vagina and you moved it in and out, even if it was only once. Even if you didn’t shoot your sperm into me… I think we did it.”

“So we had sex?” I asked, my penis throbbing.

“Yeah.” Cindy took a deep breath and nodded. “We had sex.”

“Ok.” I sat back on the couch, my mind whirling. “Wow. So we’re not virgins anymore.”

“Yeah, I guess we aren’t.”





“You wanna do it again?” I blurted out.

Cindy was silent for a very long time. Finally she slowly said, “I don’t know, Matt… I mean, I do want to cause it felt really good… but we’re brother and sister, so I don’t think we should.”

“Yeah, but we already did it once,” I countered. “So why not do it again?”

“But we did it by accident then… I don’t think we should do it again.” She sounded unconvinced.

“Look, what can it hurt, Cindy? I mean, my penis was already in you once. What does it hurt if I’m in you again?”

“I don’t know…”

“How about if we try it just once?” I asked in near desperation. “If we don’t really like it, we don’t ever have to do it again. But since we had sex once and we’re not virgins anymore, we might as well really honestly DO IT all the way just once, you know? So that we know what it’s really like.”

“Yeah… well, I guess if it’s just once, it can’t hurt.”


Cindy thought a little longer and then finally shrugged. “Ok. We can try it once more, but not ever again unless we both really want to, ok?”

“Ok!” I said, prepared to agree to just about anything if it meant my penis could return to the paradise that lay between my little sister’s legs. “So where do you wanna do it?”

“How about my bedroom?” Cindy said after a bit.

“Ok.” I stood up.

Cindy rather shakily got to her feet and we walked up to her bedroom. Once we were inside, she shut and locked the door and we stood there next to her bed looking at just about everything except for each other.

“So I guess we should get naked?” I said, desperate to move things along.

“Yeah, I guess.”

I moved first, starting by taking off my shirt. Cindy took of hers a few seconds later and soon both her and I were naked. Cindy’s eyes went straight to my hard penis while my eyes went right to the smooth slit between her legs.

We started at each other until Cindy said, “So… how do we do it?”

I put some thought into it and said, “I’m not really sure. I guess you just lay down and I’ll get on top of you and put it inside.”

“Ok,” Cindy said as she laid down on her bed, parting her legs.

I got on top of my sister, resting my penis against her preteen vagina. I was very nervous at the thought of what I was about to do, but I was also really eager to see what it was like to really FUCK and not just stick it in and pull it right out again.

Looking down between Cindy’s legs, I saw what I figured was the right place. I took my teenage penis in my hand and pressed the tip against the spot. “Right here?”

“A little higher,” she whispered.

“Here?” I said after adjusting.


“Ok.” Taking a deep breath I pushed against the spot, imagining my penis sliding easily into place just like it had before.

That didn’t happen.

What did happen was that my penis just pressed against her but didn’t seem to penetrate at all. Scowling a little I pulled back a tiny bit and then pushed forward again. Still nothing.

“Are you sure I’m in the right place?” I asked.

Cindy gave me a look. “Trust me.”

“Ok, so why aren’t I going in?”

“I don’t know. Keep trying.”

I was pleased that at least she wasn’t going to insist that I stop. I readjusted myself and applied pressure once more. This time I felt it. A very slight yielding sensation around the tip of my penis. Encouraged, I pushed a little further and looked down to see the tip disappearing into my sister.

Cindy gripped my arms. “Oh! I can feel you going in!”

“Yeah…” I whispered. I pushed again and pulled back a little to get my balance. Then when I pushed forward once more it was the same strange slide into pleasure, my little sister’s vagina almost sucking my penis into her. I let out a gasp of pure delight as the last of my shaft sank into her, my body pressing directly against hers. Looking down I could see only my pubic hair against her mostly bare pubes. I was inside my sister once again.

“Oh, Matt,” Cindy whispered, looking up into my eyes. “Oh, you’re in me again…”

“Yeah…” I whispered back. “Do you like it?”

“Yes,” she moaned. “Oh, yes… god, I like it…” Cindy wrapped her legs around mine and pulled me down on top of her, my bare chest pressing against her small breasts.

Doing my best not to cum too soon, I said, “Can I start moving?”


I began flexing my hips, moving my teenage penis slowly back and forth within my sister’s wonderful preteen vagina. Now I knew I was certainly having sex! There was no question anymore. I was officially fucking my sister, and GOD was it wonderful!

Cindy started moving under me as I fucked her. The wet and tight magic surrounding my penis started getting even wetter and tighter. It was pretty obvious she was really enjoying the sex. I was happy to see that, cause it certainly increased the chances of me getting to do it again!

Deep within my penis, though, I could feel my orgasm approaching. As I fucked Cindy, I managed to whisper to her, “I can’t… hold back… I’m gonna… cum soon…”

Cindy may or may not have known exactly what I was talking about. All she did was nod and moan a little. That was enough for me! I lost all control and pushed deep inside my sister’s vagina as my penis began firing off sending several blasts of incestual sperm up into her waiting body. I gave no thought at all to the possibility of getting her pregnant. All I cared about was the total bliss my body was experiencing.

Cindy must’ve felt much the same thing, because under me she began moaning in earnest and I felt her vagina suddenly clutch and grip at my penis as she held tight onto my naked body. I didn’t know for sure that girls had orgasms, but what Cindy was going through certainly had to be one!

When we were both done cumming, we looked into each others eyes, our minds whirling. I slowly pulled my penis out of Cindy and rolled over to lay on her bed next to her. We hadn’t meant to fuck the first time. We’d certainly intended to the second time. And now I knew it wasn’t going to be the last time.
