Chapter 2709 - NIGHT OWL SISTER

I don't think I've ever been more nervous in my entire life. I was standing right outside my sister's room, my heart pounding. It was about 5 in the morning, and everybody was sleeping. I knew my sister was a night owl and would probably be in a very deep sleep phase right now. My rational mind knew that. My rational mind knew that my chances of getting caught were essentially zero. But essentially zero and truly zero are two different things. If she caught me sneaking around in her room, I'd never hear the end of it. It's even possible that she'd tell my parents.

Groaning, I suddenly wondered if she'd tell our friends at school... What 18 year old guy needed his sister to tell everybody that he was a creep, spying on her as she slept... But no, she wouldn't. Despite being sister and brother, we got along OK. We were not really friends, nor did we share some special connection because we were twins. But we were not fighting all the time and even helped each other with school stuff. Recently, we'd even begun talking about relationships. No, I'm sure Jenna wouldn't talk about this at school. Then again, being sure and knowing something for a fact were two different things!

Taking a deep breath, I tried to calm myself. Tried my best, because after all not entering wasn't even a possibility. I had to do it, I had to go into my twin sister's room before she woke up. She and I were close, but I don't think she'd react well if she found what I left in her room... Another breath. At least, waking my parents wasn't really an issue as they were not there. And in case, even though their room was right next to my sister's, they were really heavy sleepers. "So is your sister!" my rational mind told me again. I, alone of my family, was a very early nightbird. Why was that? I was her twin for God's sake! How could Iā€” I stopped and shook my head. I was procrastinating!

I finally grabbed the door handle, closed my eyes and took one last deep breath. As I began turning the knob, I was extremely careful as I knew it squeaked pretty badly. I think it took me five minutes to turn it fully open, but it didn't make all that much noise. After that, another 5 minutes to push the door open. Inside, utter darkness. Of course, I thought, the sun hadn't yet risen, and my sister had very thick blinds on her window. Shit. Would I be able to find it? I had a pretty good idea of where it was, but I couldn't really drop on all fours and feel around with my hand, could I? That would make too much noise. "But, but, but!" my mind said one last time, as if it had any chance of convincing my fear-filled mind, "you could say her name out loud and she wouldn't wake up!"

It was true. From time to time I'd had to wake her up, and it was borderline funny just how hard it was. I smiled, thinking about those memories. Then I thought back to the last time I had to wake her up. It was about two months ago, and she must have forgotten to put her alarm on. Mom asked me to wake her up or else she would be late. I knocked and called her name a few times, although I knew it wouldn't work. Entering her room as she was sleeping was always a bit stressful. What if she was naked, with the covers off? And while this possibility was scary because of the implications (I couldn't wake her up, couldn't walk back downstairs and tell my parents I had seen her nude...), it was also intoxicatingly erotic. But it had never happened.

Even on that last occasion, she hadn't been naked. But she might as well have been. Two months ago, after coming in, I had seen two pieces of lingerie on the floor. Two very small pieces of lingerie. Making sure Jenna was still asleep, I had knelt and looked at them. They were bright red, made from very fine lace and I'd guessing that they must have cost a fortune. Who was the lucky guy this month? Grinning, I got up and had looked up at my sister. While the comforter had been pushed on the floor, Jenna had still been completely covered by the blanket. Yet, the sight had been extraordinarily erotic nonetheless.

Clearly the blanket was very thin, and as she was sleeping she must have tucked it under her. Her body had been in obvious relief, and I felt a pang of desire. She was rather tall, with long lean legs, flat belly and great breasts. They had been unmistakeable then, even when squashed down by a taut blanket. It hadn't the first time I felt such forbidden desires while looking at my sister. As any hot-blooded brother was won't to do, I had tried to sneak peeks at her as she would change, come out of the shower, bend over, etc... But I hadn't had much luck. Truthfully, except for one very special moment, I'd only had as much luck as anybody else who'd seen her in a bikini.

But once, only once, I had gotten a gift. I had been lucky probably because it really happened by accident. I had dropped my spoon during dinner and had had to kneel on the floor to reach it under the table. Looking up, I'd seen my sister's legs right in front of me, and seen that she hadn't worn panties that day. Her legs had been demurely closed, but I saw a few golden hairs of her blonde bush. I'd quickly prayed, asking the Gods of luck to make her open her legs. No help. I'd also known that I couldn't stay there long, so I had to pull out. I still carry that memory preciously...

But as wonderful as seeing her bush had been that day, my sister's best asset were her breasts. Last summer, after a long fall, winter and spring of exponential mammary growth, her breasts were transformed. Jenna had been a late bloomer, frustrated by her small breasts most of her teenage years. Last year though, everything had changed. She went from using 32B cup bras to her current 34E cups. I wasn't guessing, as rummaging in her underwear drawer was one of my secret guilty pleasure.

In any case, I shook my head and focused on the present. Even if it had required a lot of shaking to waked her up that day (as my eyes had been glued to her moving breasts), I was afraid of waking her up now. In perfect silence in her room, where I wasn't supposed to be, looking for that specific object, I was afraid that my breathing would wake her up. No use for it, I had to get my thing back. I walked in and silently cursed that even my dark-adjusted eyes couldn't make sense of anything. I knew her room's layout, and slowly made my blind way around her bed.

Very slowly I knelt down, using my hands to feel around on the floor. Nothing. I knew I had to start again, more slowly this time, but my heart skipped a few beats every time the floor was creaked. If only I had a small light! Then it hit me: use your phone! But my phone was back in my room, in my jeans' pocket. Taking a slow but deep breath again, I got up and carefully walked out. Making sure to set my phone correctly in my room, I walked back to Jenna's room. As time was passing by I went in a bit faster. Kneeling on the other side of her bed, I was ready to turn the light on, knowing it was a big risk. Well, at least it wasn't as big a risk as letting Jenna find that thing in her room.

Shaking my head, before turning the light on, I tried again to understand why I had acted so foolishly. Last night, all alone in the house, I had indulged in one of my most intense fantasies. When Jenna's breasts bloomed last year, my fantasies of her had bloomed as well. I had never touched her, nor tried to manage an "accidental" contact. I wanted her badly, but I wasn't about to go full lecher on her either. In my mind, though, things were very different.

One of the best ways I had of satisfy these fantasies was what I had done last night. Grabbing my fleshlight and some lube (I had found Jenna's own bottle, but hadn't dared to use it yet...), I made my way to her room, then to her lingerie drawer and then to her bed. with some of her panties and bras on my chest and face, I used and abused my fleshlight in her bed, surrounded by her scent. I knew it was bad, it was really bad, but it was better than trying to fondle her or install hidden cameras... At least, that's what I told myself. I knew that if I ever got caught doing this I would be in really, really deep trouble.

And that's exactly what almost happened. My parents had been gone for the week-end, so no worries there. And Jenna had left on a date with her current boyfriend. The guy was pretty cool, and I enjoyed his presence when he came around. The only thing that bothered me was the fact that every time he shook my hand, my mind reminded me that that same hand had touched my sister's breasts, ass and pussy. In any case, he was a night owl like my sister and I had known that Jenna wouldn't be back until very late.

When I'd made my way to her bed, it had been only 9:30. I should have had hours in front of me. As it turned out, I did not have hours. When I'd heard the door being thrown open violently, I had just climaxed, my hand and belly sprinkled with cum. I had been grinning, relieved that none of my sperm had reached Jenna's lingerie. My fleshlight had been discarded on the floor, as I'd wanted to make sure that any sperm remaining in it wouldn't stain the blankets.

I'd jumped up in surprised, and barely registered my sister's swearing downstairs. I'd had to move really fast, and so I did. Jumping up I'd grabbed her lingerie, trying to keep them sperm-free, and pushed them in her drawer. They didn't end up exactly where they had been, but that drawer wasn't perfectly ordered in any case. Moving back to the bed, I'd made it as best as I could in 3 seconds. Now my biggest problem was that I'd been naked with cum on my chest. I'd walked outside her room and peaked around the corner of the wall leading to the stairs. When I'd seen Jenna walking briskly to the kitchen, I'd darted to the bathroom. I was safe. Safe, except for the fact that I had completely forgotten about the fleshlight.

After cleaning myself off, I walked downstairs and found my sister being both very sad and very angry. I'd sat next to her, rather awkwardly, and had asked what was wrong. Remarkably, the hour long discussion that had followed had brought us closer than ever before. She had told me that her boyfriend, now ex-boyfriend, had tried to convince her to let him come sleep here, knowing that our parents were away. He had been really insistent about it even though she had said no. Not that she hadn't wanted to, Jenna told me, but our father had been very explicit about this rule. The discussion turned into an argument and a fight. Things were really bad, but when he said that if she didn't let him come, he would break up, Jenna exploded and stormed out of the restaurant.

Thinking about all this, kneeling in my sleeping sister's room, I knew I was procrastinating again. Then again, I thought back on how surprised I had been to learn that she and her boyfriend had never had sex. They had fooled around quite a bit, and were on the verge of going all the way. Not anymore. In the very intimate atmosphere, I had dared to ask her if she was a virgin. She wasn't. She had had sex a few times with her last boyfriend, and while it had been interesting, it hadn't been really fun. Jenna had thought that with Carl it could have been a better "take two" attempt, as much fun as it was when she imagined when she masturbated. Jenna had paused and reddened, as if she had just realized she was talking to her brother and not one of her friends. I reddened as well, but we both smiled at each other.

So that's why I was feeling like a true creep right now. Not only was I in my sister's room, acting like a consummated stalker, but I had defiled her bed last night. Well, I smiled, that was rather overly dramatic. With one last deep breath, I turned my phone on. Seconds later I found my fleshlight, squeezed between her bed and her nightstand. She probably hadn't seen it. And then it hit me: of course she hadn't seen it! If she had, she would have exploded again and demanded explanations! As stressed as I was, I felt a deep wave of relief engulfing me. Why had I been so afraid that she could have seen it?

This adventure could have ended right there. I could have grabbed the fleshlight, turned the light off and walked back to my room. But life had something else planned for me. I considered the fact that turning my phone off would render me blind, my eyes not dark-adjusted anymore. So I got up with the phone on, and saw what I shouldn't have seen.

The faint glow of my phone illuminated my sister's body, which was partly covered by her blanket. Partly covered. She was lying on her belly, her head turned away from me and her arms under her pillow. The blanket was pulled sideways, covering all of her upper body, but precious little of her left buttock and both legs. My eyes focused on that buttock, and I felt them widening. Wandering down voraciously, they then slid to her hip and thighs, then calves and feet. Damn! Even her feet looked sexy!

I felt my stress and anxiety turning into desire, forbidden desire. The illicit access to what little skin her bikini bottom normally hid only added to the thrill. With a will of their own, my eyes were now back on her ass, on the perfectly rounded and smooth skin I had fantasized about for so long now... Granted, I would have given anything to see her on her back, to feast on her glorious breasts, but this was nothing short of a worthy gift. I realized that I had remained perfectly still since getting up, and took a slow and deep breath.

My first thoughts were of turning my phone off and leaving the room. Getting caught like this, my phone-camera in my hands, would have been even worse than for simply sneaking in. My seconds thoughts were of staying here for the entire night, watching her as she moved around, hopefully revealing even more of herself. Before being able to think any further, my erection made itself very obvious, painfully obvious actually, as it pushed hard against my boxers. I had to leave. But my body didn't want to. I was still frozen there, a deer in headlights. Eventually, my rational mind reasserted itself and reminded me of the hell I'd pay if I was caught here. Very carefully, I moved away and left the room, one last look at the glorious sight that was receding back into darkness.

Back in my room, my heart felt like it was head banging to power metal music, and I felt every beat in my cock. Grabbing my bottle of lube quickly, I began shaking my head, wondering why I hadn't leaned in closer in case I could have seen her pussy between her cheeks... Seconds later I was abusing my fleshlight again, regardless of the fact that it was still half-full of my sperm. I came in less than a minute. I headed to the bathroom to wash it and myself thoroughly, and still my heart was racing. What a wonderful accident, with no consequences! I would live with memories of this sight for a long time, feed it into my fantasies for months!

I was grinning like a maniac as I walked back into my room. But as I crossed her closed door again, another thought hit me: will this be nothing more than a one time deal? As I reached my room and locked the door behind me, my mind blossomed with myriad plans and ideas, many excuses if ever I was caught, websites that could inform me about the best low-light cameras, ways to convince her to always sleep naked and risk assessments of the possibility of actually touching her... As I saw the sun rising through my opened window, I was still grinning, thinking that I had stumbled by accident on a treasure trove...

After Jenna woke up at around 10, I greeted her a good morning. While we talked as she was eating, I tried to detect anything out of the ordinary. I was now pretty sure she hadn't seen the fleshlight, but I wanted to be as sure as possible. She was dressed as she usually dressed in the morning, with a long shirt, panties and some sort of sport's bra. Nothing out of the ordinary, but this morning I felt a lot more attuned to the curves and skin that was revealed. But I was suddenly extremely distracted. When she finished her last bite, she cleared her throat and asked me a very direct question, "So, little brother, now that you know a lot more about my sex life than before, are you still a virgin yourself?"

Before I could even process her question, or even consider responding to her long-running "little brother" running tease, I had to try and recompose my mind. For some reason, I never thought that my own sex life could be the subject of a discussion with her. Stupid, I know, but there it is... I coughed, trying to stretch time and think of a reply. Jenna laughed, making it clear that she had known how I'd react. "Oh you little..." I said, laughing with her. "You got me there!"

"What? You misunderstand me brother! I had a pretty good idea of how you'd react, but I was serious. I opened up yesterday, so, how about you?"

I shook my head, still smiling, and took a deep breath, realizing that I had taken an awful lot of deep breaths today. "Er, OK. Well, yes I am. Fooled around a bit with my last two girlfriends, but nothing really sexual. Not even oral, given or received..."

I was red faced when I finished, but she was still smiling at me very warmly. "See? That wasn't so difficult? We're brother and sister, twins even... Maybe we could help each other?"

"Help each other?" I asked, dubious.

"Yes. I'm sure you have a lot of questions about girls that you can't exactly ask Dad. And I know you can't get good answers from the net. Gods no! There's a huge desert between abstinence websites and porn. Maybe porn isn't as bad as some people make it out to be, but you have to know it's all show and not real life! Right?"

"Yeah, I knew that..." I said, what I'd call a grey lie. Quickly, I added "You want us to talk about this to each other? Right now?"

"Why not?" Jenna asked, seemingly perfectly at ease about her idea.

"Er... well... I'm not sure that it's..." A pause, a dose of forced courage, and then "Well I'm not sure it's such a good idea to talk about such things while I'm wearing nothing but my boxers."

Now I was red faced again, probably more then a minute ago. I was already feeling the slightly tingling sensations in my penis, felt a small trickle of blood flowing in. I knew that if I kept talking about sex with Jenna, most of her naked legs stretched out in display, I would have a real erection. An erection that would, as a matter of fact, be just as much in display as those legs. I was surprised to see puzzlement on Jenna's face. It took her a few moments to realize what I meant. "Oh!" was what she said when it clicked. "You mean that you'd get an ā€”" All I could do was nod, and try to keep my smile from turning into a childish giggle. "Oh!" she said again. "But I thought guys only had erections when looking at girls they found hot." I groaned, completely trapped, looking away from her. And she said "Oh!" again.

I was more uncomfortable than a fish out of water. I hadn't said a single word in the last two minutes, but she had figured out something I would have killed to keep private. Why did I have to talk about boxers? "You see!" I said, my voice rising in stress, "I knew it wasn't a good idea!" And then I got up and left, hiding my growing erection with my body as I walked up the stairs.

In my room again, with emotions profoundly different from those a couple of hours ago, I dropped on my bed. I was feeling so bad that my erection was fizzling away fast. How the fuck did this happen? How the fuck did I accidentally tell my sister I found her hot? I could have replied that simply talking about sex could also cause erections. No need for hot girls. Heck, I've even gotten them while talking about sex with my male friends! And while one of them was gay, it was not my case. But the fact that didn't say that, and remained silent instead, Jenna understood it as an admission of guilt. The guilt, or sin perhaps, of having the hots for your own sister. And now she knew.To my surprise, I heard her knock on my door. "Jenna, please leave me alone." I replied quickly. "I feel bad enough as it is. I'm really sorry..." To my greater surprise, she opened the door and walked in.

"Sorry? Why should you have to be sorry?"

"Well, I told you I thought you were hot. My own sister!" I said, still not looking up at her.

"Ryan. Look at me. You didn't say anything. I figured it out..." When she saw I was had nothing to add, she kept going. "One of the things you need to learn about girls is that we love compliments. And yes, that was a bit weird... But look. If you had been staring at my legs or breasts and said "Sister you're hot!", it would have been pretty bad... But that's not what happened. It was my fault. Bad sister!" she said with a grin. A very contagious grin. It nearly worked on me. "But you know what happened to me last night. Receiving a compliment from you was good timing, Ryan."

I looked at her, trying to be absolutely sure that she wasn't teasing me. "Are you serious? I understand that if I had only revealed that I found your really beautiful or fun to be around, that would have been OK. But that'sā€”"

"Do you?" she asked, her grin turning a bit playful.

This time I grin, shaking my head. "Of course I do! But that's not the point. What I said, or rather what you learned on your own, was different. And, precisely because of what happened to you last night, wouldn't that bother you to learn about it?"

"You believe that I think you're like that jackass of an ex boyfriend?" she asked, clearly stunned.

"Well, why not? Wasn't his unspoken message exactly the same?"

"Yes, but that's not what bothered me, little brother. What bothered me was that he couldn't take no for an answer and tried to blackmail me." She sighed, looking at me. "Look, Ryan, I didn't exactly learn that you thought I was hot this morning, you know. It's been rather obvious for a long while now. But stop, don't look away. It's not a problem. Listen. The fact that you've had the hots for me for a long while yet never tried anything stupid like hugging me too long, give me playful slaps on the ass as we play basketball, or try to make lecherous grabs seem like accidents, well that says a lot about you."

In the following silence, I felt both good and bad. While it was true that I had resisted many of these ideas and urges, I did spent a few minutes staring at her naked ass only hours ago. Nevertheless, she was looking at me with her dazzling smile and I finally returned it. "Ok then..." I said. "But clearly we can't exchange these question in our underwear. Half my mind is forcing the other half not to look at your thighs and the hem of your shirt!" I finished, laughing. She laughed with me, but didn't try to rearrange her shirt. "How about we ask these questions via email?"

"Deal!" was her quick answer. She then got up and opened her arms for a hug.

"Are you kidding me? You just said... Jenna, I think you missed something important about me, you, talk of sex and boxers, Jenna..."

"No I didn't. Now get up now before it becomes impossible!"

And so I did. Jenna and I barely ever hugged each other, so this was kind of a first. I was instantly overwhelmed by the sensations. Her naked thighs on my naked thighs were the first sensation. But very soon her large breasts moulding themselves on my naked chest threatened to unmake me. A normal hug lasts one or two seconds. This one lasted for at least ten. By the time she released me, my erection had nowhere to hide, and my sister would have had to be mentally retarded not to notice it. But she didn't say a word. Walking out of my room, she said, over her shoulder, "I'll go first. Check your emails in five minutes.

Left alone in my room, stunned, I had a huge stupid grin on my face. What the fuck had just happened? There had been a very naughty but specific plan in my head involving early bird visits to my sister's room, but somehow it had all changed into this sex-ed email thing. Sitting down at my desk, firing up my emailing app, I waited. A few minutes later, I got her first email. "Can guys cum more than once?" I grinned at the directness of her question, and sent her a quick reply. "Most of the times, yes. But not always. If the first climax is very intense, it may be game over. Of course, I don't know how it feels to have an actual girl try to revive a spent cock, but I know that sometimes after I cum nothing seems arousing. Sometimes though, a quick climax only leaves me wanting more."

I was pretty nervous when I pressed "Send", but laughed when received her reply. "Thanks little brother. I'm waiting for your question!" Turning around on my chair, I asked her, out loud, "Right now?"

"Sure, why not?"

Turning back to my computer, I typed my first question, one that I've been wondering about for a while. "Do bras hurt?" A minute later, I got her reply: "Most of the time, no. But it depends on a lot of things, like what we do, what type of bra it is and, of course, the size of our breasts. I've never heard Karen complaining about that, for instance." Karen was one of her friends who had pretty small breasts. "When you have larger breasts, you need to buy good ones, otherwise it's going to hurt at the end of the day. For example, the one I've put one as I was waiting for your question is very nice and I know it won't bother me despite the fact that I, well, I have rather large breasts. :-) "

I grinned at her last sentence, and the smiley face. When I sent her a thanks, she asked, aloud from her room, "Can I ask another one?" I agreed, and seconds later got a ping. "Is flaccid size always proportional to erect size?" Smiling again, I wrote my reply. "It depends. Some cocks are growers, some are showers. Some of the guys I've seen in the showers after gym class look absolutely huge. But some of these cocks only get harder, not longer, when erect. Other guys have really small flaccid cocks that double or even triple their length when erect. So you can't really know." It felt really weird talking about this with my sister, especially since I could hear her dressing in her room right as I was writing this. But we were both curious, so I sent her my answer.

"Thanks for the clarification, Ryan." she said from her room. I have time for one last question before I have to leave.

So I sent her this one: "Are all girls bi-curious?" I heard her laughing as she read it, so I was a bit nervous as I waited for her reply. "I'm sure they're not all bi-curious. But I think that girls feel more free to explore with each other than guys do. Seeing two girls kissing is a lot more common on TV than seeing two guys kissing. And porn is filled with bisexual girls. At least bisexual girls on screen. I know of a lot of girls that have tried, but for most of them it's only exploration, not something that will end up defining the rest of their sex lives."

As I finished reading her reply, she came into my room and kissed my forehead, saying "See you later!" She had chosen a very tight shirt, and I could even resolve the lace of her bra underneath. I could also see that her nipples were very erect, which gave me an idea for my next question.

The rest of the day was pretty uneventful. Our parents came back late that evening, around 9 or 10, very pleased with their trip. Having risen very early this morning, even for my standards, I crashed early and found sleep almost immediately. When I woke up, a quick look at my clock told me that it was close to 5 o'clock again. I sighed, took a deep breath and tried to transform this groggy state of near wakefulness into real sleep again. Then memories came flooding back through the grog and my eyes shot wide open. I had a mission this morning!

I got up, grabbed my phone and put on my boxers. I then opened the door to my room and try to detect any sound whatsoever. There were none, of course. I was the only early bird in the family. Carefully, I walked out of my room and crossed the hall to my sister's room. Part of me felt bad for invading her privacy like this, but another part of me was as thrilled as I've ever been thrilled in my life before. We could indeed learn from each other, be it in the form of questions, or visions... I grinned, then turned her door handle very slowly.

Once more I made my way inside slowly, trying to find and memorize the spots where the floor creaked the most. Minutes later I was next to her bed again, and I turned my phone's light on. Less spectacular. Jenna was still lying on her belly, but was this time fully covered by her blanket and her face was turned towards me. Maybe she always slept on her belly? I thought about going on the other side, but she was really close to this side. I kneeled down next to her carefully, thankful of the thick rug on this side of the bed. I spent many minutes like this, trying to make out all the curves and shapes through the blanket. But at some point, I realized that her bikinis had given me a lot more skin to look at...

Could I dare lift the blanket? Of course I could. My heart was still pumping harder than usual, and I was very nearly trembling with excitement. I gently placed my phone on her nightstand, aiming it at her but not her face. Delicately, I lifted the blanket from her arm, trying to minimize any new contact with her skin. Eventually most of her arm was freed, and I could see her shoulder, part of her back and, of course, the side of her breast. I imagine that girls with smaller breasts, lying in such a position, would completely cover their breasts. Not Jenna. In front of me, inches away actually, was the generous side of my sister's right breast. Of course I couldn't see her nipple, but the soft, pliable flesh was right there. I leaned in, maybe four inches away, staring at those curves.

And smelling her skin. I had no smell fetish, but I had to admit that my sister's odour was very sweet that night. Pulling back, a huge grin on my face and a huge erection in my boxers, I looked downwards. A minute later I had pulled most of her her blanket up over her, exposing roughly half of her body to my small light. And hungry eyes. Once again I stared at her ass, round and full and, I knew because of all the swimming she did, firm.

My heart was racing as I feasted on her revealed silhouette. Kneeling right next to her, I pulled my cock out of my boxers and began caressing it slowly. Silently. If Jenna opened her eyes right now, I was a dead man. She was more open-minded about sex than I thought, but there were limits... A brother perving over her as she slept was way, way beyond that limit. By instinct, my free hand reached to her. Luckily, I managed to stop it in time. Then, as I was now truly pumping my cock, I wondered if I could pull it off. Could I touch her?

I knew my mind was being overloaded with sex right now. But on the other hand, I knew just how hard it was to wake her up. I dared. Slowly, I toucher her upper arm, inches away from her breast. Soft, warm, pliable... Delicious. This was so bad, and so good at the same time. I was very close to climaxing, and I knew I couldn't do it here. That would be a death sentence, as I knew how hard cum was to remove from clothing and blankets.

So I stopped and released my cock, leaving my hand on her arm. A few minutes later, my cock still rock hard but knowing I was not on the verge of climaxing, I removed my hand and let it hover just over Jenna's breast. And then, finally, I touched it. Sure it was just the side of her breast and I couldn't quite massage and maul it like I'd like. But I was in heaven. When my other hand grabbed my cock, I felt a surge of pleasure, and knew I had to leave. I replaced her blanket as slowly as I could, all the while my mind screamed that it wanted to reach orgasm. A minute later, alone in my own bed, my cock finally exploded into one of the best orgasms of my young life. I ended up with cum all over my belly, chest and even a few drops on my face. And one, I discovered a few hours later, on the wall behind my head. I laughed as I discovered it, then cleaned it carefully.

I was in a gloriously good mood the following morning, and my entire family asked me why that was. No reason, I said! It was now Monday, and they were all up by seven and a half. Jenna and I went to school, and I spent most of the day dreaming about my night. Once I even had to race to the bathroom and masturbate in a stall! When I met Jenna after school, as we were waiting for the bus, she grinned and said "What? No more questions?"

I laughed, having completely forgotten about the questions. Sitting in the bus side by side, which was highly unusual as we normally sat with our friends, she asked it again. "So, anything?"

"Actually, yes. I'll send it to you as soon as we get home."

"Oh come on little brother..." I grinned, realizing that I didn't mind that nickname anymore. "You're fully dressed now. Why don't you ask it now, it's not as if we have other things to do!"

I groaned, took a deep breath, and leaned in close to her. She was till wearing her very tight shirt, and I could see the curves of her breasts and the faint relief of of her bra's lace. Nonetheless, I asked her "Do girls' nipples really get hard when you're excited?"

Jenna grinned, then leaned against me, very close to my ear. In fact, she was so close that her breast was pushed against my arm. She whispered, "Yes they do. They actually can get painfully hard. That's why most girls I know love to have their nipples sucked on..."

I shook as Jenna went much deeper than I had thought, and pictured me sucking on her own nipples. But she wasn't done. "Of course, cold air can also make them hard, much like we get goosebumps for the same reason."

Looking quickly at her breasts, I could indeed see that her nipples were beginning to show. It hadn't been the case earlier. Noticing my glance, Jenna looked down. Giggling, she said, "Isn't it chilly here?" before laughing.

It wasn't. Not by a long shot. I grinned and laughed, knowing that she must be feeling exactly like I had yesterday, talking about boxers and erections. In fact, I was glad of my jeans and my packsack above it. Jenna leaned in again and said "My turn!" Placing her mouth very close to my ear this time, she said "Do all guys love anal?"

I nearly choked at her question, and a very clear image of a porn flick with a crazy anal scene popped into my mind. I groaned again, saying "I'm going to die... Or at least I'm going to hell...". Jenna laughed, knowing that none of us were really religious. I took a minute to think about it, then leaned in to try and answer her. "I think so... Most of the guys I know like it. In porn movies, at least. I think I only know two guys who've actually had sex. And none of them told me they had tried anal..."

"Hmmm, interesting... Most of my friends are afraid of it."

"Are you?" I asked, before I could really think about. Then, very quickly, I added, "Shit! I'm sorry Jenna... That's too personal, I'm sorry..."

"Well, it is quite a lot more personal. But I'm game to answer if you tell me what you think about it."

"Hmmm, OK."

"All I can say is that I'm really curious... I've never tried it, obviously, but I've done some... er, exploration... And I really liked it." Jenna's skin was really red, from her cleavage to the root of her hair. And her nipples were clearly very hard. But she had a small smile on her face, waiting for my own answer.

"Obviously I never tried it either, but I confess that it's one of the regular fantasies I explore with porn..."

"You watch porn?" she asked, faking surprise. I laughed with her, nodding. Then she added, "Often?"

"Er, yes..."

We laughed again together, and thankfully we were home and got out of the bus. Jenna laughed as she detected that my gait was somewhat different because of my hard-on. Throwing caution to the wind, I reached under my belt to rearrange my cock. She laughed even more. We spent a nice and uneventful dinner with our parents, then headed straight for our rooms. Two minutes later, I had sent Jenna a new question. "How often do girls masturbate?"

"Gosh, I don't know! Often?" she was teasing me because of my earlier answer. Then she added "I think it varies a lot. Some almost never do. You know Chloe? She told me last year that she had never done it. Ever. And some of my other friends, whose name I'll keep secret, do it more than once a day..."

"Wow! More than once a day! That's more than most guys!"

"Really? I though most guys masturbated whenever they had the chance!" was Jenna's quick reply.

"Nah... It ends up hurting!" I said, and seconds later I heard her laugh in her room.

"My turn!" she sent back. "What do guys love the most about bikinis?"

"Oh my Gods... How much time do you have?" I replied, laughing.

"No, I know you love them, but is there something specific, or a type of bikini? Do you prefer regular bikinis, string, with support up top, or just straight spandex, etc..."

"Jenna, you've thought about this a lot more than guys do! I guess for most guys, the more skin that is shown the better!"

I heard her sigh loudly in her room. "That's dumb Ryan!" she wrote back. "For example. If I got out of my room wearing my bikini, I guess you'd like that, right?"

"Er, of course..." I wrote back, not sure of where this was going.

"But if I came out wearing lingerie, would you like it more?"

Surprised by her question, I cried out "Are you serious? You don't know the answer to that?"

After she shushed me from her room, I replied, "Of course I'd like it more!"

"So then it's not just the amount of skin that's important..."

After reading her words, I stopped and thought about it. It would indeed be extremely different if she came out wearing only lingerie. As I was thinking about it, she popped another follow-up question. "Ok then, let's be more specific. What do *you* really like about bikinis? It can be something very specific..."

Once again we were on the side of personal questions... The thing is, I knew exactly what I liked about bikinis. "Well, since you ask, I really like when the bikini top doesn't go down all the way back to the girl's chest..."

Despite everything I still felt a bit of nervousness as I waited for her reply. I grinned when I read her reply. "Oh! You mean like my red top? When you can see a fine line of skin between the elastic and the chest?"

"Exactly!"

"You like that one? I was sure you preferred the black one..."

"Oh come on now, that's like asking a parent which of their children is there favourite!

I heard Jenna laughing out loud in her room. Then she wrote that she had to focus on her homework. So did I. But as I went to bed at 9:30, to the dismay of my parents, I was grinning, thinking about what wonders the next morning would bring.

Seven hours later I was up, and decided to refrain from putting my boxers on. It's not like it would alleviate the hell I'd get if ever I was caught. I was extraordinarily surprised and pleased by the way my relationship with my sister was growing, but I didn't even want to try and imagine a conversation in which I'd tell her about these nighttime visits...

This morning, naked right next to her, I was already hard and my blood pressure was sky-rocketing: Jenna was on her back, her head turned away from me. I could already see the mounds of her breasts under the blanket, and knew that in mere minutes I would get my very first glimpse of them. More than glimpse, I was planning on staring. Kneeling on the floor next to her, I gently and slowly removed the blanket, and managed to uncover one of her breasts. I was in awe, I was in heaven. Even on her back, her breast was breathtaking. Part of my mind knew that age would rob it from some of it's perkiness. But right now, it was a overwhelming sight. I was sitting there on the mat, staring at it as if my life depended on it.And then my hand moved. And I didn't stop it. Seconds later, making sure that my hand wasn't cold and clammy, I delicately placed it on her breast. I was shaking, and knew I couldn't. Trying my very best to focus, I left my hand there but regained control of my breathing. Very gently, I squeezed her flesh and felt goosebumps rising all over my body. And hers. Even in the dim light I could see the tiny blonde hairs on her breast rising. And then, her nipple. In the space between my thumb and index, I saw her nipple growing. And growing! A minute later it was fully distended, rising clearly above the rest of her breasts, begging to be touched.

And so I did. Very gently, I touched her nipple with my fingers, squeezing it slightly. Now kneeling up, I was above her, playing with her nipple like someone afraid to make dominos fall. At some point I finally released it, in order to straighten my back and stretch the tensions away. Looking back at it, as hard as ever, I knew what I needed to do. Placing my hands carefully on the mattress, I leaned in. Leaned in and finally felt my lips close on my very first nipple. I almost fainted with pleasure, my blood pressure shooting wildly up. I knew I couldn't give in and really enjoy it, but I had to.. I had to! But I couldn't!

Somehow I managed to walk the fine line between teasing myself and waking Jenna up. As I pulled away, I could see my saliva glistening on her nipple. And then Jenna moved. I froze, my heart skipping quite a few beats. Luckily she didn't wake up, but simply moved in her sleep. Moved her legs. Apart. Quite a fair bit apart actually. And then, as mesmerizing as her breast and nipples were, my mind was focused on something else. Moving away from her side, I walked to the bottom of the bed. Carefully again, I pulled the blankets up. And up. And up until I revealed her pussy. Or, at least, her panties. I hadn't expected her panties, but it would still be pretty good.

Kneeling on the bed as carefully as was possible in my situation, I inched forward and leaned over her panties. And took a deep breath. My first whiff of pussy. Of an actual live pussy. It was intoxicating! I had smelled her panties once in a while, but this was something else. Very very gently, I kissed her panties right on top of her mound, just where I thought her clit was. Jenna moved again, making a small sound in her throat. I should have been scared off, but I was so excited that I didn't budge. In the ned, Jenna didn't move all that much, but I sat back on my feet and realized just how brazen I was. Looking at her nude body was something. Petting her, kneeling between her opened legs, smelling her pussy?

I pulled back, and stood there looking at her opened legs. I felt a low rumble at the back of my throat when my eyes focused on her pussy, and images of pulling them down filled my mind. Shaking my head, I knew I had to leave before I did something special. And so, led by my raging erection, I left her room silently and went to mine. Les than a minute later I was erupting again, covering my blankets with cum. Later, I was grinning like a fool as I was wiping the blankets with a damp towel, trying to clean my mess as much as possible.

Tuesday went by as usual, but while I was really looking forward to the bus ride home, Jenna was with her good friend and they sat together. She gave me a sad look as she saw me close by, but it would have been really weird for her to sit with me. We ate and spent a part of our evening with our parents, as they still wanted to show us more pictures from their trip. Jenna and I looked at each other and laughed a few times, both aware that we were indulging them. At around 9, we scampered to our rooms and I sent her the first question. "Are big cocks as much of a turn on for girls as big boobs are for guys?"

"Hmmm, You like big boobs? Hahaha! As for your question, I don't know. One of those friends who masturbate a lot told me that her boyfriend had a huge cock, something like 7 or 8 inches. I'm not sure I believe her, but in any case she says she loves it. I just don't know what most girls believe, Ryan. I'm sorry. Er, if I may ask, why do you care? ;-) "

I grinned as I read her last question, and tried to let a smiley face answer her own. "No reason... :p"

"You have a large cock?" was her cheeky reply. I paused after reading it, not replying instantly. Two minutes later I heard her say, "Come on, don't wuss out on me now!" from her room.

I finally wrote, "How do you define large?"

"Well, anything around 7 inches is pretty big."

"In that case, yes."

I heard Jenna laughing in her room, before she replied "Nice! And good to know... Now, my question! Do guys prefer girls who are shaven down there?"

"Hmmm, porn movies certainly seem to think so. But I'm not sure." I said. Then decided to plunge into the personal. "I prefer one long strip of hair above the pussy, trimmed short. And maybe a bit more hair on blonde girls than brunettes..."

"Wow Ryan, that was rather precise!"

"Hey, I do what I can to please!"

"Thanks for the answers little brother."

"No problem."

We spent the rest of the evening apart, and once again I went to bed early. I got up at around 4:30, which was very early even for me. I knew I'd be tired later today, but right now I was as awake as could be. Naked again, I creeped in my sister's room, taken by surprise by a lit lamp. It was a small desktop lamp, across the room from her bed, but it was till quite a bit brighter than my phone's light. Jenna must have fell asleep as she was reading, not bothering with the light. All the better for me! Jenna was on her back again, but this time both her breasts were already uncovered. Soon I was kneeling beside and above her, staring at her skin, her flesh, her nipples, her curves, her slow breathing... Bending forward, I grabbed one of her nipples in my mouth again, making my tongue twirl around it.

As soon as I did, Jenna moved, and I pulled away just barely quickly enough so that she didn't touch me. She turned on her side, her face just on the edge of the pillow and bed. Both of her breasts were mostly hidden by her arms and blanket, but as soon as I looked at her face, I saw that my cock was only inches away from her mouth. I grinned, not sure I was game to do it... But I knew I could kiss her. Kneeling way lower than before, I moved in slowly and kissed her lips. I had kissed a few girls before, but this was a first, a first kiss with my sister. Utter strangeness, utter delight.

As I kneeled back upwards, I knew I had to do it. Pushing my hips forward, I placed my glans less than an inch from her mouth. The sight was breathtaking. I began masturbating slowly, making sure not to touch her. Taking a pause, I relaxed a bit, taking deep breaths. One of her hands was just dangling over the bed, and I scooted down towards it. Slowly, I pushed my cock down under her hand, and let the natural upward tension do it's magic. For the first time in my life I felt a girl's touch on my cock. Sure, it wasn't a hand job, but the jolt I got from the feeling was still amazing.

Moving back up, I kneeled in front of her face again and brought my cock back next to her mouth. As I began masturbating again, I felt the tip of my cock touching her lips. I froze, convinced that she'd wake up. She didn't. Pushing it back once more, I left it there and enjoyed another stolen first: the first lips on my cock. Pulling back, I let a glob of my saliva drop on the glans and spread it all over. When I touched her lips again, the lubrication made everything a thousand time better. I was now rubbing the tip of my cock against my sweet sister's lips. By pushing just a bit more, I parted her lip and felt her teeth. When Jenna moved her arm back under the blankets, I pulled away, scared stiff. Well, stiffer.

Jenna then yawned. My eyes widened as I saw her mouth opening wide, even if I knew she was going to close it in seconds. I could force my cock in right now, but that would result in instantaneous wakefulness. And hell. So I resisted. On the other hand, I discovered with joy that the pillow prevented her from completely closing her mouth. When I pushed my cock back against her lips, I felt her jaw giving in. As it happened, I had a decently large cock, with erections somewhere between 6.5 and 7 inches. I moved sideways to get the best angle and decided to push in a bit further. At first it was peculiar. In one way it was utter delight and pleasure. But her teeth on my glans was rather unpleasant. Until I pushed through.

By some sort of reflex, Jenna closed her lips around my cock for a few seconds and began breathing through her nose. She even moved her tongue inside her mouth, just a bit until it was settled again. I stopped all movements, as the last thing I wanted was to cum in her mouth! Well, not the last thing I wanted, but I knew I couldn't do it. I was getting my first sleepy blowjob. I placed my hand on her head and began fucking her mouth with extreme slowness. I didn't go far, at most 3 inches. I didn't even think about the fact that her continued sleep was bizarre. I was in heaven. Then she closed her mouth around my shaft again, and pressed her tongue against the underside of my cock. She was still sleeping, and must be in some sort of erotic dream caused by my actions.

I was ready to die here, but knew I couldn't stay any longer. I gave three or four more pushes and pulled out. Looking at my cock, I saw that it was glistening with her saliva, and that every single vein on it was distended. It was pulsing with every heartbeat, and I knew I had come very close. Jenna moved again, turning on her back, with her left leg pulled up and sideways, making her knee poke from under the blanket. I stood there staring at her for a long while, waiting for my cock to return to a normal erection.

After that, I moved down the bed, standing at her feet. Gently, with more control now, I pulled the blankets away from her legs. I was pleasantly surprised by the fact that Jenna had gone to bed fully nude tonight. So once again I was treated to another first: my very first sight of a girl's pussy. Despite my overwhelming feelings of lust and appreciation, I found myself grinning. Jenna's pussy was trimmed exactly like I liked. She was blonde, and now had a nice trim of pussy hair right above her lips. Maybe it was a lucky coincidence, maybe it was a twins thing, or maybe she had shaven it according to my preferences...

I shook my head, knowing that that was impossible. But as I kneeled down on the bed, pushed one of her legs away and looked closer, I could clearly see that she had shaved herself very recently. In fact, it seemed extremely fresh: I couldn't see a single trace of a stubble. I grinned again, realizing that I didn't exactly have an unusual preference. I had a feeling that most girls who were not fully shaven were either completely untamed or had this strip... And so I kneeled down and leaned in very close. Again her scent filled my nose, but this time I was fascinated by the sight. It was not that I was learning anything new: porn had made sure that I knew what a pussy looked like. But this one was live, real, warm and even a bit wet. That dream must be good! It was also my sister's. Forbidden and illicit, so of course extraordinarily thrilling.

If placing my cock against her lips had been the obvious thing to do earlier, tasting her pussy was the obvious thing to do now... How could I do anything else? I leaned forward, craned my neck at a strange angle, and, very slowly, touched her pussy with my tongue. The contact was electrifying. As I pulled my tongue back in my mouth and tasted her, I was floored. Jenna tasted slightly spicy, very savoury and it reminded me of her specific odour. Very similar to the smell of her sweat, but different as well. I laughed as a strange thought crossed my mind: I was pretty sure I would have recognized her by taste!

Moving forward a bit more, I opened my mouth and began exploring more deeply. Jenna was definitely wet, and pretty soon I had her juices all over my lips and cheeks. I was trying my best to contain and slow down my movements, but an alarm was ringing at the back of my mind. How the fuck could she still be asleep? From all I'd learned, some of it from porn, admittedly, Jenna should be writhing in pleasure right now. But she was just there, sleeping. And breathing hard. As I paused to look up, seeing her breasts rising perkily upwards, I could see her eyes were still closed, her mouth slightly opened still.

Before I plunged back in, my alarm rang again, a lot louder now, but I just couldn't stop myself. Could a girl climax during sleep? Shit! I should have asked her that! My tongue was now deep inside her pussy, pushing the walls of her vagina open. Suddenly, another alarm surprised me: I was about to cum. Unconsciously, I had been rubbing my hard cock against her bed, and I was taken unawares by a developing climax. I pulled away from her and off form the bed, looking around in panic. No tissues, or socks anywhere in sight. Damn! I should have kept my boxers! I could try to contain it with my hand, but I was pretty sure I'd overflow.

The first thing I saw was a pair of her panties, probably the ones she'd had on today. I grabbed the flimsy pink fabric and wrapped it around the head of my cock. Just in time! I did my best at containing my cries and moans as I was ravaged by my climax. At that point I was standing right next to Jenna's bed, legs spread for balance. Once that last spasm of pleasure and ejaculation was done, I grinned, looking down at her panties. They were full. But as far as I could tell I had succeeded: I couldn't find a single drip anywhere.

I was now coming down from the lust phase, but as I looked at her slightly opened mouth, I knew I had to do something else. I dipped my pinky in the pool of my sperm and placed it just inside her lips. Rubbing my finger against her tongue, I smeared a tiny drop of my cum into her mouth. By reflex, she closed her mouth and swallowed. My cock hardened again at the sight. Then, Jenna stretched, pushing her hands down and squeezing her breasts together in the process. Looking down, she cupped one of her hands around her pussy for a second or two before relaxing into sleep again.

I couldn't believe it: I was rock hard again, ready to fuck so soon after a climax, and Jenna was right there, her legs opened, her pussy all wet and obviously in an aroused but sleeping state. Putting her soiled panties on the floor, I walked back to the foot of the bed, in awe of the sight before me. I kneeled on the bed again, inching forward between her legs. Suddenly, she reached down again to her pussy, masturbating right in front of me. She then whispered, "Oh Elliot..."

Elliot was one of her exes, maybe the one she'd had sex with. I was staring at her, mesmerized, as she kept masturbating harder and harder. At one point she pulled her knees up and kept on rubbing at her clit. I moved forward even more, and was eventually right above her pussy. If I opened my own legs, I would drop to her level. Which I did. I then pushed my cock down and felt it touching her very wet pussy, just below her fingers. Seconds later I felt my glans opening her lips and slipping inside her.

And here I was, with my cock finally inside a girl's pussy. All I wanted to do was push in completely, but I knew it would mean that I would instantly wake her up. I had about two inches of my cock inside her as she writhed around it, moaning louder now. She grabbed one of her breasts, squeezing it hard, and soon did the same with her pussy. Jenna then froze for a second, and arched her back upwards. As she crashed down, she was obviously having her climax.

And I knew that was when I had to pull out. By a miraculous effort of will, maybe because I had just orgasmed, I did pull out. Pulled out and stood up as I watched her body slowly wind itself down. I was still painfully hard, with my sister's pussy juices on my cock. I walked away as quickly as I could, closed the door behind me and was masturbating even before reaching my bed. I came again, not as profusely as the two previous nights, but still in utter delight. As I drifted to sleep, I counted my blessings: I had seen my glorious sister fully nude, I had kissed her, caressed her breasts, sucked her nipples, touched her ass, eaten her pussy, pushed my cock inside her mouth and now even inside her pussy. I fell asleep in a daze, grinning like a fool.

When I woke up about an hour later, I thought about all this again, and had to masturbate one more time. Then I thought about it all, and felt somewhat depressed... Sure I could try and do that again as many times as I wanted, but I couldn't go any further... I had been very lucky to trigger a sex dream and catch her masturbating in her sleep. How the fuck would I be able to put my cock inside her again?

The family breakfast was as normal as could be, and Jenna seemed to be in a good mood. Of course, I thought, after such a climax! She was dressed rather sexily this morning, with a very generous cleavage. I wondered if Mom would say anything, but she didn't. We rode together in the bus to school, and she suddenly leaned into me "Do you have any more questions?"

"Er, sure... You sure you wanna do this here? The morning bus is not as noisy as the afternoon one..." I looked around, and there were only 8 other people with us.

"Why not?" she asked, a strange expression on her face. "All we have to do is sit even closer together..." And so she did, scooting right up against me. "So? Shoot!"

"Hmmm. Do you watch porn?" I asked, not even realizing that I was asking a very personal question.

Jenna didn't react to that fact either. "Of course! Not all girls are innocent angels!" she replied into my ear, laughing.

"What's your favorite?" I asked, already excited, my cock getting harder.

"You first!" was her reply.

"Ok... Remember yesterday when you asked me about anal? Well, one of my favorite scene is about that. It's very short, and before you say anything I know it's impossible to do that without preparing beforehand... But still, I was floored. Two girls are talking in a club, sitting on barstools, wearing very very short skirts. One of the them says that she'd like to be sodomized right there and then. Suddenly, one of the guys in the bar walks up behind her, pulls her towards him on her stool and pushes her dress around her waist. Two seconds later, he's hilting his cock in her ass and proceeds to fuck her ass in front of everyone."

When I moved away from Jenna's ear, I could see that she was flustered, and that the fantasy had had quite an effect on her. "Gods!" she whispered... "That was so hot!" she leaned in, adding, "Of course you were right, you can't do that without preparing beforehand... But damn that was hot!" After taking a deep breath, she shook her head, grinned at me and said "Ok, now me. I had another scene in mind, but yours reminded me of one of my favourites. They're quite similar, actually."

As she was talking, she was leaning very, very closely against me. Her breast was pressed hard against my arm, and I could feel it's warmth and firmness every time she moved. I could also feel her warmth breath against my ear, and her lips touching me from time to time. "Picture this..." she said. "You have a nude girl lying on a blanket, head propped up on her hands as she's reading a book. She has earphones on. Suddenly, a naked guy appears in the background and walks towards her slowly. At one point he's just standing there above her legs, his erect cock fully ready. When the girl doesn't react, he squats down, pushes his cock into her pussy and slides in completely. The girl jumps in surprise, then grins as he begins fucking her..."

I was writhing in my seat, trapped between the window on one side, and her thigh and breast on the other. I must have been just as flustered as her. But before I could reply, Jenna said, "My question now. Do you like the taste of pussy?" I froze. A second ago, I was beginning to enjoy the strange mix of tension and pleasure, talking about this with my sister in the bus, her body nestled against me. It was uncomfortable and fun at the same time. But now, when I heard her question, my mind flashed back to a couple of hours ago when I was licking her pussy.

Trying to be cool, thankful that the school was in sight, I said "Well, yes... It's very different than I had imagined... But I do like it."

"Really? Not all guys do... Tell me, who did you taste?" she asked, not looking at me.

"Well, that's another question... And in any case we're here, so we have to stop." I replied quickly.

"Hmmm... Saved just time, little brother. But, "she paused, then looked directly into my eyes as we were getting up, "didn't you tell me that you never had oral sex a few days ago?" I froze again, and she added "So either you lied to me then, or you tasted a pussy recently. Very recently... Which do you want to confess?"

And with that she stepped away from our seat and walked down the aisle and out of the bus. I didn't manage to catch up to her, and in any case I'm not sure I wanted to. I spent the entire day trying to figure out if she knew about my early morning visits. Of course not... We were more open to each other, but I had no illusion that she would be interested in going so far... Fuck it! I had put my cock in her mouth! Had she woken up with the taste? And as she was climaxing, did she fake being sleeping? Shit! Can girls climax during sleep? I sure can, having woken up with cum in my boxers many times. Can girls have wet dreams? Shit! She knew! No... She wouldn't act so normally.

As I thought back to this morning, trying to remember every detail, it suddenly hit me. Her panties. FUCK! I was in math class and nearly fainted. I had filled her panties with my sperm after eating her pussy, thinking that I would clean them afterwards. But instead, I had climbed back onto her bed and pushed my cock inside her pussy as she masturbated. Shit!!! I had forgotten them on the floor! She fucking knew!!! I felt sick, lying on my desk, feeling a huge pit open beneath me. It was all over, I was going to hell...

But as I closed my eyes, trying to contain my emotions, I remembered that she had acted normally this morning. She had been in a very good mood and had even continued with the questions and answers. Fuck, she had even asked if I liked the taste of pussy. Her pussy! She knew and she liked it! Straightening up in my chair, I took a deep breath and felt my mood changing dramatically. I tried to find her during the rest of the day, in vain. She eventually found me as we all crowded, waiting for the bus. I tried to act as normally as possible, but I think I failed.

As the bus finally pulled out of the school's parking lot, she grinned, looking at me. "So?" she asked, as innocently as she could given the nature of the question.

"What?" I asked, feigning ignorance.

"Which is it? Did you lie to me a couple of days ago, did you lie about tasting pussy, or did you taste one recently?"

I grinned, unable to resist. But I didn't know what I could answer yet, so I said as much, "I'm not sure I can reply... Not sure the girl in question would like it if I told you her name..."

"Oh. I see..." she was still grinning. But as she opened her mouth to ask another question, I cut her off.

"I have a question for you. Have you ever been taken during sleep?"

Somehow I managed to keep a straight face as my sister's eye nearly bulged out of her sockets. She stared at me for a long while before smiling. "Well, yes, actually. And I liked it. A lot."

We were both smiling, but had nothing else to say. She knew I had done what I had done. I now knew she knew, and had accepted and wanted it. And now she knew I knew that she knew. That's a lot of shared knowledge! It was also very strange. Sweet, but strange. We arrived home, ate with our parents and went to our rooms. I was sitting at my computer, hoping for an email from her. Nothing. Then again, I didn't feel like asking her another question either. When I went back down to the kitchen to find something to eat, I found her there. She grinned at me, but again we didn't talk. We both looked at the clock, knowing that the night would be... interesting. The only thing she said before going back up to her room was that she going to hit the shower and go to sleep early tonight.

I was left alone in the kitchen, somewhat dumbfounded. I think we were as close to being honest about everything as we could, without actually saying it. As I walked up the stairs a minute later, already feeling an influx of blood in my cock, I had one last moment of doubt. I confronted the fact that I was drunk on lust. Maybe I was interpreting everything she was saying wrong? Was her question about the taste of pussy just a coincidence? Could be. Then again, what about the cum filled panties? Is it possible that I kicked them under her bed and she hadn't found them yet?

I spent the next hour in my bed, wondering what was going to happen. Usually I was the first to fall asleep, but tonight I remained awake until I was sure everybody else was. Looking at my clock, it was now 11, and the house was perfectly still and silent. I took a deep breath and got up. Stripping down completely, if I was going to do this I was going all in, I carefully walked out of my room. Following my routine I walked inside Jenna's room and closed the door behind me. Pitch black. Shit. One more moment of doubt. When my eyes adjusted, I spotted Jenna's phone on her desk, and used it to create a light.

As soon as I illuminated her bed, my doubts evaporated. Jenna was completely naked on her belly, her blankets nowhere in sight, and she had placed one of her panties on the bed next to her. On them, in bright red letters, was the phrase "Fuck me!". It couldn't have been clearer. But Jenna was sleeping, or at least faking sleep. It looked like we were going to play this game one last time.

I walked around her bed, and admired her body for a few minutes. Playing with the light from her phone, I illuminated her thighs, ass, the darker space between her cheeks, her slim lower back and the curve of one of her breasts. I was already as hard a a rock, but I wanted to take my time. Not too much though. Turning the light off and discarding the phone, I kneeled on the bed above her feet and dropped on all four above her. Slowly, savouring the thrill, I leaned down. I was grinning like a fool, enjoying the pleasure of this illicit moment all the while knowing she had allowed me here. Maybe even from the first time. Had she seen my fleshlight and allowed everything that followed?

I grinned again until I was surprised, in this darkness, by her ass hitting my nose. Jenna's scent filled my senses, a sweet mix of her own scent and traces of soap from her shower. Not mindful now of waking her up, I pushed deep, burying my nose, mouth and cheeks in her dark and deep cleft. I felt my nose against her asshole and angled my head so that my mouth finally touched her pussy again. As I opened my mouth and licked her lips, I heard a small moan from her. I smiled against her pussy and kept going, knowing that she was awake.

I did the best I could. I alternated between deep pushes against and inside her, burrowing in the tight space between her thighs and ass before pulling up to breathe. I had both hands on her asscheeks, massaging and mauling them, opening them wide to give me better access. I drank her, I drank her in, tasting her juices like a man dying of thirst. I felt my nose and cheeks covered with a slick mix of saliva and pussy juice as I slid even deeper.

Since that first one, Jenna didn't moan anymore, but I felt her twitch and spasm against me. She was clearly awake, but kept up the game. Wanting more, I dove as deep as I could one last time and slowly pushed upwards. My tongue was hard against her hole, her lips and then brazenly, slowly, I licked my way directly across her asshole. Jenna shivered again, but didn't make a sound.

On all fours again, I walked higher over her until my cock was right above her well lubricated pussy. I whispered, still in game, "Oh my God Jenna... I'm going to fuck you. You're going to be my very first, I'm giving you my virginity. And you're never going to know it because you're asleep. I'm going to take you, take your very sweet pussy... Last night was a peak, a first hesitant taste... Now, I'm going all in. Gods..." Holding myself up with one arm, I pushed my cock downwards with the other. When I felt my tip touch her burning hot pussy, I closed my eyes an pushed in. One or two inches in, just like the last time. Then I let myself fall upon her, burying myself as deep as I could go.

This time Jenna moaned, then grabbed my arm. "Fuck me harder little brother..." I was overwhelmed, thrilled beyond all belief. I knew she knew I knew... but hearing her whisper it! Damn! Closing my fists in the blankets, I pulled upwards and ground myself against her. I felt her asscheeks being crushed by my lower belly as my cock drove itself as deep as it could. When I pulled nearly completely out and rammed back in, the sound of her flesh being slapped made me grin. After I did it again, Jenna whispered, "Shhh... Mom and dad are on the other side of the wall..." I paused, eyes wide open, but mostly because of the added thrill. Releasing the blanket, I forced my hand under her body and grabbed her breast. At the same time, I pushed my cock back inside her and heard her moaning. Picturing my mom and dad sleeping a couple of feet away, I grinned and fucked her harder.

At the same time, I knew I couldn't hold on for much longer. A virgin on his first fuck? No way was I going to hold as long as I wanted. With an effort of will I pulled out and lay down next to her, on my back. It didn't take Jenna much time to understand. Kneeling up next to me, she turned the lamp on. In glorious light, I saw her naked, moving beside then above me. Squatting over my cock, she grabbed it and placed it against her glistening lips. As she impaled herself, I felt her burning hot flesh moulding itself around me until her lips were spread wide at the base of my cock. Then she rose up. I was staring at he majestic breasts, swaying and dancing as they were, when she let herself fall back down upon me.

Surprising me, Jenna asked, "So, little brother... You think you can put your cock in a sleeping girl's mouth without waking her up?" Before my stunned silence, she added, "Or lick and suck her pussy? Or even putting your cock inside her pussy?" She was fucking me slowly as she talked, probably aware that otherwise I would cum really quickly. "Hmmm, dear brother. You just can't, silly. When I found your fleshlight, my first reaction was one of utter surprise. I picked it up, smelled it and was about to show it to our parents and have fun with you. Then I paused and touched the soft pussy. And felt your sperm on my finger..."

She was grinning, slowly moving upon me, both up and down and side to side, teasing me. "And then, finally, I tasted it. It just happened. I think I was very excited on that morning, and I probably didn't masturbate because I had woken up too late. But here I was, with your sperm in my mouth." She kept fucking me as she talked, and I had to stop her, holding her down with my hands on her hips. "Ooohh," she cooed, "my little story has an effect on you? Well then. Listen, little twin brother. Do you think you're the only one of us to try and sneak peaks at the other? Oh yes, I'm pretty sure I know about most of your attempts at seeing me naked, or the times you try to find excuses to talk to me when I sunbathe with my bikini. And yes, I even remember when you looked at my pussy from under the table."

"What??"

"Oh come on... When you got up your entire face was red. And I knew I hadn't worn any panties, knew you had a good angle and I even opened my legs a bit wider for you."

"What? Really? Why?"

"Why not?" Jenna said, smiling at me from above. She then leaned forward and pressed her breasts on my chest. "As I said, I do enjoy when you don't wear a shirt..." she said, caressing my chest with her breasts. "I think that I decided to keep your fleshlight incident private was because..." she paused, taking a deep breath, "I masturbated in your bed a couple of times myself!"

"What?" I repeated again, flabbergasted.

Jenna laughed at my reduced vocabulary. "Cat got you tongue?"

"Well yes... not a cat, but your pussy. Think my tongue still tastes of you?"

Without warning, Jenna pressed her grin onto my mouth and we kissed our first real kiss. As I felt the surge of sensations and emotions flowing through me, her tongue dancing with mine, I grabbed her hips and lifted her up. I felt her firm flesh under my fingers and pushed her down at the same time I drove my cock upwards into her. I knew I couldn't hold on for a long time, but I didn't care. Breaking the kiss momentarily, Jenna whispered, "Keep quiet, but fill my pussy with your sperm brother... I want to feel it overflowing all over your cock so that I can lick it all up when your done."

Which was, obviously, much more than I needed to climax. My climax was painful at first, as if my entire body wanted to course through my cock and nestle inside my sister's pussy. Jenna kept her mouth on mine, not really kissing but making sure I wouldn't cry out. Somehow we succeeded, and I only spasmed, trembled and twisted under her as I came and came in silence.

As I was finishing with a few last spurts, I felt Jenna raising herself slightly up, making sure my sperm didn't go too deep. Gently, very gently, she pulled away some more as I twitched like a crack addict in detox. Finally, my cock popped out and slapped against my belly, but Jenna didn't move. Instead she hovered right above me, and I felt my sperm dripping down on my cock. Suddenly, she broke the kiss and moved downwards over me, whispering "Put a pillow over your head and bite hard!"

In my current state I couldn't even form another "What?", and looked around for a pillow, contented and dazed by the shock of the climax. When Jenna's tongue touched my cock, my eyes opened wide in surprise. As she was lapping up my sperm, she looked up and said "I rather like sperm, little brother. A lot, actually... Wanna feed my fetish?" This time I didn't even try to answer. Instead I grabbed the pillow, squashed it over my head and bit hard. Jenna proceeded to lick and suck all my cum from my cock and belly, and then, seeing that I was still relatively hard, took my cock into her mouth.

In seconds I was hard again, enjoying my first blowjob. My first blowjob from a girl who was both delightfully talented and my sister. By now I had both my hands pressing the pillow over my head, trying my best not to cry out in pleasure. As I felt a second climax growing in my cock, I couldn't believe my luck and abandoned myself to my cum loving sister. My second climax wasn't as intense or copious as the first one, but Jenna was latched onto my cock like a bloodsucking vampire onto a neck. I shook and spasmed until I couldn't take it anymore.

Throwing the pillow on the ground, I grabbed my sister's head with both hands and pulled her off of my cock. Then, holding her shoulder, I pulled her up and onto her back on the bed. When she opened her legs, I rolled above her, my still hard cock against her pussy. "Put it in!" she moaned.

"I'm done! I'm spent!" I replied, my breathing still ragged.

"No you're not! You're still hard, and I'm wet enough to take three cocks at once! Put it inside and just stay there..."

The mix of pleasure and pain that I felt as I pushed inside her once more was overwhelming. I knew I couldn't climax a third time, but as I settled inside her, feeling her arms holding me tight, I knew that this night was not the culmination of my nightly explorations. Instead, it was the beginning of something completely new, and so much better. But soon I discovered that Jenna could come again. "Oh gods... My little brother's sperm in my belly, my mouth, on my lips..." she was trembling under me, pushing her clit against me. She really had a sperm fetish! When her climax exploded, even though I was above her, I had to hold on hard. She was trashing like a madwoman, and I was surprised, amused and thrilled all at once.

Eventually she quieted, her own climax spent. "Jenna," I whispered into her ear, "want me to fill you with cum every night?"

"Hmmm... Why only every night? There are a couple of secluded spots at school... Wouldn't that be even better?"

I shook my head against her neck as she laughed, and even though I realized right then that my sister had a very high libido, I would learn later that I had profoundly underestimated it. As the years went by, with girlfriends and boyfriends entering and leaving our lives, this secret bond held firm. I ended up learning more about sex, love and myself from her than from any of my other girlfriends. And to think it all started with a forgotten fleshlight...
