Scarlet Afterglow

Movie nights with my sister were a tradition between us, going back well over a decade. The unspoken rule was that they were only for us. Even at times when we hardly spent any other time together, it maintained some kind of special bond between us.

The kind of funny thing was that Naomi used to always fall asleep later in the evening. She was apparently so cozy and safe next to me that she just couldn't help herself.

It had become a point of pride for Naomi at some point that she stayed up all the way through. Perhaps she was tired of the teasing about she couldn't last until the end.

She'd regressed since then, pride failing against the stresses of adult life. I had to admit it felt nice knowing I was her refuge from it all, and that snuggling with me had returned to being a near-foolproof way of putting my sister to sleep.

A little more confusingly, Naomi had also started sucking her thumb in her sleep. I couldn't remember how long ago it had been since she'd done anything like that. But like clockwork every week now she fell asleep and sucked her thumb while cuddled up warmly against me.

I tried one week, just to see what would happen, pulling her hand gently away from her mouth. Naomi's cute face took on a slight frown in her sleep and her lips kept looking for something. If I released her hand, it would slowly return and she'd comfortably return to sucking her thumb.

Because apparently I just couldn't let something like this go, I moved Naomi's hand again and this time left my hand next to her lips. It was an even slower thing, but my sister found one of my fingers and happily sucked it into her mouth.

It was an odd feeling having my little sister sucking on my finger. Intimate in a way I wasn't sure I was comfortable with. Not with her. But she did seem happy after all, and it wasn't unpleasant, just weird.

It became something of a game for me the rest of the night. Swapping out my fingers, or putting two in at once, or withholding them a while. Just to see what Naomi would do, or if she'd wake up.

I did feel kind of bad for messing with Naomi while she was sleeping like that, but that went away when she woke up.

"Welcome back," I said.

"What?" she asked blearily.

"You fell asleep again," I teased.

"Max! I did not!" Naomi said.

I frowned slightly. "You most certainly did."

"I think I'd know," she insisted, even as she wiped drool off her cheek.

"Oh yeah?" I said. "So what happened at the end of the movie then?"

"They kissed and lived happily ever after," Naomi said promptly.

I narrowed my eyes. "Lucky guess. More detail?"

"Nuh uh," she said. "I think you were asleep. You tell me more detail."

I most definitely hadn't been asleep. The annoying thing was I'd been so busy playing with my sister that I'd been ignoring most of what had been going on in the movie.

"Um... an argument," I mumbled. "And, like, a legal thing, and a misunderstanding...."

"Wow, so convincing," Naomi said, rolling her eyes hard. "Try and stay awake next time Sleeping Beauty."

****

The way Naomi had irritated me last time meant that I'd lost all reservations about messing with her again next movie night.

Granted my scheming only went as far as buying a pacifier in the interim, with the intention of having her wake up with it in her mouth and try to explain how she 'definitely didn't fall asleep.'

"Try not to drool on me when you fall asleep this time, Maxxy," Naomi told me as we started our movie.

"I'm sorry, do you think I drooled all over you?" I asked incredulously.

"Well yeah," she said. "Could at least drool on yourself instead."

I shook my head and didn't fight it. My plan was a go, and we'd see what she could possibly try and do to wriggle out of admitting that she fell asleep later.

It started out exactly according to how I'd imagined. Naomi fell asleep, tried to suck her thumb, and I replaced it with a pacifier. Easy peasy, bing bang boom.

My sister sucked on that thing a little too eagerly though, and in her contented, sleeping state she caught my arm that I'd wrapped around her shoulders before I could withdraw it. She hugged my arm rather cutely to herself as though it was a teddy bear or a pillow or something. Incidentally, a little distressingly, holding my arm such that my hand was right on her tit.

I couldn't tell if things were more cute or more weird at that point. Not that I didn't enjoy my sister's tit. It was lovely and soft under my hand. But she was my sister after all. It wasn't the sort of thing I was meant to enjoy.

But... she was sleeping. My sister was totally oblivious to it. She had, in fact, put me in that position to start with. I'd freed up both of our hands entirely by giving her something else to suck on, so arguably it was partly my fault, but she'd actually made the forbidden contact herself.

Granted she was asleep and I wasn't, so we were probably back to it being more my fault than hers.

I couldn't get away from her though. Not that I tried overly hard, I didn't want to wake her, but Naomi only clung tighter to my arm when I tried to move it.

Sighing, disbelieving of my own decision making, I rotated my arm a bit instead and fully cupped my little sister's breast. If I was stuck I might as well enjoy it, I supposed.

I could argue that maybe I was trying something silly to make her release my arm, but that wasn't true. I was actually just curious about my sister's tits now that I'd had this brush with them.

"Dammit," I whispered.

My cock had reacted. Like yes I was feeling tits, so technically it was appropriate to get hard, but this wasn't really the time for that.

But I had made the decision to feel Naomi up, so blaming my penis at this point probably wasn't going to be productive.

Naomi wasn't helping anything either. The more I fondled her, the tighter she hugged my arm, and even started making adorable little moaning noises while sucking on her pacifier.

"Going to hell?" I asked out loud.

I pinched Naomi's nipple very, very softly. She moaned even louder and her pacifier dropped out and tumbled to the floor.

"Yeah," I murmured. "Going to hell."

I tried to reach down to grab the pacifier again, but only knocked my sister's head to my lap, and still wasn't able to reach anything. She let go of my arm at least, giving me some freedom back. But I still wasn't going anywhere without waking her.

I really didn't have any excuse to feel my sister's tits anymore. I kind of wanted to anyway, but I had more restraint than that. At least sort of.

I tried to watch the movie that was still playing. Not that I was able to pay any real attention. Apparently I would still rather watch Naomi as she brought her hand to her mouth and resumed sucking her thumb.

It was a long, agonizing few minutes before I gave in and put a hand back on her tits. They were right there. I'd tasted the forbidden fruit and I couldn't leave it alone now.

It wasn't fair. Naomi had such perfect little tits to play with, and even though she was dead asleep she kept making horny little noises while I touched her too. I wanted to be a good big brother, but I didn't get a lot of opportunities to play with boobs and I was getting really turned on.

Not that any of that was a good excuse or anything.

Even less excusable was the next horny thought that came to my mind. Naomi wanted something to suck on, so....

I fought it as long as I could, but horniness and curiousity were a powerful combo that had led to many a bad decision for me personally, and I suspected society at large.

I unzipped the front of my jeans, moving as slowly and carefully as I could. If ever there was a time not to accidentally wake my baby sister up, it was while I was in the middle of sticking my penis right in her face.

Everything was ok. She barely stirred as I got my cock out. The transition as I nudged her hand away from her mouth and replaced her thumb with my cock was nerve wracking. Again, not a good time for her to wake up.

But I was ok. In fact I was great. Naomi was still asleep, and was sucking even more happily away than ever before, and it was with her lips wrapped innocently around my penis.

Holy fuck it felt good though. Like it wasn't exactly a proper blowjob or anything, but it was certainly a cute girl sucking on my dick, and that was pretty close. Even if she was sucking on it more like it was candy than a cock.

The best I'd previously done in my sex life was receiving a few mediocre handjobs. Like I could jerk myself off way better than the girl who'd attempted to do the same for me. I appreciated it at the time, and it felt good to have someone else touch me instead of doing it myself, but it paled in comparison to my sister right now.

I closed my eyes and leaned my head back, sighing quietly in sheer pleasure. My sister's mouth was one of the very best things I'd ever felt in my life. She just kept sucking on me. No hurry, no slowing down, just moving her lips in a constant, heavenly rhythm.

I watched most of the rest of the movie that way. Leaning back comfortably, getting my cock sucked by my little sister, freely feeling up her tits whenever I wanted. If I was going to hell anyway, I might as well get my money's worth.

Naomi did eventually make me cum. The constant movement of her lips on me was the slowest and most decadent of buildups in my entire life. Using my hand meant I could control when I came a lot better. With Naomi doing it, I didn't dare so much as move a muscle to urge her onward.

I'd thought there were bad times for her to wake up earlier, but I had to admit that if my sister woke up just as I was cumming into her mouth, that would be by far the worst of all possibilities.

I groaned out loud as my long-delayed orgasm finally erupted, and I had a moment of panic as Naomi choked on the cum that suddenly flooded her mouth. Luckily she was fine and swallowed in her sleep just the same as she'd kept right on sucking on me through it all.

Some cum did leak out from her lips, but mostly Naomi just accepted it unconsciously and drained me so nicely dry. Including continuing to suck every teeny little bit that stubbornly remained until the end.

I had to pull out of her mouth after that. I was sensitive anyway, but she was so gentle that it kind of felt nice even so. The problem would be if I let her get me hard again, I'd just have to let her keep going. I had already pushed my luck way beyond the breaking point.

It was a struggle to get my penis away, my pants done up again, and to find and kick the pacifier from earlier under the couch with my foot, all without waking my sister.

I breathed a sigh of relief when the end credits came up on our movie, and Naomi then rolled over a little and stretched as though it was a trained response for her to wake up to the credits rolling.

"Good movie," she said.

I snorted. "Did you see any of it?"

"Yeah! The whole thing!" Naomi said firmly. "Why?"

I thought about testing her again. She'd been deep asleep after all, and I knew it. But given that she'd just given me the best and indeed only head of my life, perhaps discretion was the valorous path in this case.

"Enjoy it then?" I asked instead, going along with her.

"Yeah," she said. "I don't know why exactly. I feel really content after watching it."

I bit my lip to avoid saying something stupid. I knew exactly why I felt good afterward. I couldn't speak for her feelings.

Naomi found some of the cum on her face that had escaped her filled mouth earlier. I experienced a half-second of existential terror before she sucked it right off her finger again. Her brows furrowed.

"What snacks were we eating earlier?" she asked.

"Um...."

"That's such a nice taste, but I don't remember eating anything like it," Naomi said, puzzled.

Feeling somewhat dazed I tapped my cheek, mirroring some more cum on her face. "There's a little more there."

Naomi wiped her cheek off and sucked her finger clean again. Totally surreal to watch my sister eat my cum right in front of me without being even slightly aware what she was actually tasting.

"Well whatever it is, maybe we'll have it again next week," Naomi said.

I nearly let out a big, involuntary groan. Again, I knew I was the one being bad, but she just made it unfair. Saying things like that of all possible combinations of words she could have chosen.

"Gee, bro, sure hope you cum in my mouth again next week."

For fuck's sake.

Naomi, oblivious to my lewd thoughts, stretched again and started padding away. "Anyway, off to bed. My turn to pick a movie next time, right?"

I thought about responding, but couldn't. What was there even left to say?

****

I spent most of my week daydreaming about my sister. That was worrisome. I just really, really wanted to put my penis in her mouth again. And I could not for the life of me find anything at all that distracted me enough from those thoughts.

Movie night came up again, finally. It was the most I'd ever looked forward to anything, I thought. Even beating out Christmas when I was younger.

Not even the movie itself, of course, it was taking advantage of my sister that had my highest, most desperate anticipation. I was a very bad brother.

But Naomi was so cute and tempting when she fell asleep against me yet again. Her little mouth begging to have something bigger than her thumb in it.

I'd prepared a bit better this time around, knowing what I inevitably was going to do. I wore boxers to watch the movie instead of pants. Naomi raised an eyebrow at that initially.

"Looks like you're ready for bed," she teased. "Awfully suspicious for someone who 'doesn't fall asleep'."

I stared at her in disbelief.

"I... I just wanted to be comfy," I said, covering for the fact that she'd short-circuited me by totally misinterpreting my reason for under-dressing.

"Relax, bro, I'm messing with you," Naomi said. "What's up with you tonight? You're all weird."

"Um...."

"I think you're right though," she said, and slipped her own pants off and only leaving her panties and a thin shirt on. "Maximum cozy for Max and Naomi," she said in a sing-song tone, making 'cozy' rhyme deliberately with her own name.

"Sure. Right," I said, trying desperately to look anywhere other than my sister's panties.

"Problem?" Naomi asked with the most wicked of grins on her face.

"No," I said.

"Oh good. Because I thought maybe you decided you could show up in your underwear but you were going to get all embarrassed if I did the same," she said.

"Perish the thought," I said, repressing a groan as my sister turned and bent over briefly, giving me a full view of her ass pointed right at me.

My plan was about to backfire hard if I got an erection right now. I didn't know what happened, how I got myself in this position. All I did was sneak one little blowjob off my sister. And made plans to do it again. And did so without nearly enough care in the making of said plans.

Ok, so once again it was largely my own fault. I needed to do better.

But Naomi didn't make it easy. Some of the way she acted suggested she knew exactly what her hanging out in her panties was doing to me, and then some of it was just like we were chilling as usual with no weirdness.

Some of my own discomfort was purely the fact of how we were both dressed, which I'd started. I hadn't expected it to mean I'd be seeing my sister with her long, smooth legs and her perfect little barely-covered butt flashed around. Every time she needed to get up and pee or grab a snack or drink, I couldn't help myself but follow her movements wistfully.

Sharing a blanket with Naomi was actually a stroke of genius on my part. It covered my lap better so I could stop worrying so much about getting hard, and it covered her scantily clad body better. Most importantly, it encouraged my sister to settle down and really get cozy.

Which, deny it all she wanted, led to Naomi falling asleep midway through the movie again.

I'd actually been so focused on trying not to stare this time that I didn't notice her being asleep until I caught a very soft sucking sound. Naomi was sucking her thumb again.

I breathed a sigh of relief and didn't move for a while yet, just to be sure. But as soon as I tried putting a finger in her mouth, she was as happy as ever to suck on that instead.

It would have been interesting to know if my sister was having naughty dreams when she was sucking in her sleep like this.

"Naomi?" I called very quietly. "Nae-nae?"

No response. As expected and hoped.

I gently kicked our blanket off and laid Naomi down in my lap again. I switched hands for putting my finger between her lips so that I could use my nearer hand to rub her breasts. I even went bolder this time and put my hand right under her shirt to caress her bare tits. They was amazing and wonderful, and so soft and perfect.

Really all of this was my sister's fault, because who the hell was supposed to have to handle finding out how cute and sexy and perfect their little sister was anyway?

I sighed. No, it was still my fault.

But I kept feeling her anyway.

At least now I didn't have to worry about getting hard right in front of her. Which was good because I got hard quick. Practically just from cupping my hand to her breast.

And I definitely couldn't get harder once I managed to tug Naomi's shirt up and get a good look at her naked tits. Just as perfect to the eye as to my hand. They weren't big, but they had such a beautiful shape. Such a perfectly artistic set of breasts on my little sis. As if I needed that temptation of top of everything.

There was no point holding back any longer. I carefully got my cock out and fed it to my sleeping sister, sighing as her lips locked on to me again. God that felt good.

That was all I wanted these days. That one previous chance had ruined me. I just wanted my penis in my sister's mouth again. Which was not a noble pursuit, but it was still quite possibly the best, most pleasurable feeling of my life.

I leaned back and played with Naomi's perfect little breasts while she sucked on me with her same quiet, sensuous rhythm. It was like they were made for my hands. Just the most ideal, sexy, forbidden playthings.

I though I would be happy just with that, entertaining myself while I waited for Naomi's exquisitely slow blowjob to bring me to orgasm. But she got so wiggly and squirmy in her sleep, her thighs flexing and squeezing together.

Maybe my sister was having a naughty dream. It kind of looked that way. Or maybe not even a dream. Admittedly, having my cock in her mouth and playing with her tits might have something to do with her sleeping reactions.

Carefully, unsure if this would be the thing that got me caught, I moved my hand down Naomi's cute body. I gently slipped my hand between her closed thighs and rubbed my fingers over the front of her panties, over my little sister's pussy.

She sighed in her sleep and paused her sucking for a moment as I rubbed her. Her thighs loosened, giving me more room, and she quieted down almost entirely. It took a few moments but she also started sucking on my penis again.

I was learning some things. Figuring my sister out. All in the most inappropriate ways, of course.

It seemed like as long as I kept rubbing Naomi's pussy, she was utterly docile and content and kept right on making my cock feel good.

I flew too close to the sun in my sudden hubris of feeling like I had everything worked out sufficiently for my purposes. I made Naomi cum. I didn't mean to, exactly. It seemed like a nice thing to make her cum in return as long as she was doing it for me, but I hadn't thought it all through and hadn't really thought about the consequences.
But they didn't. Somehow I just kept rubbing my little sister's pussy, she had her cum, and then she settled down again to let me keep playing with her.

I sighed in relief, not daring to stop rubbing her now. For all I knew it was the only thing keeping her asleep in the wake of her orgasm.

It took a while and a lot of gentle coaxing to get her to roll back the way I needed so she could suck on my penis. As it turned out, pressing my cock to her face was what ended up working. She felt it, and her mouth sought it out, the rest of her body rolling back toward me a little to accommodate.

I carried on only edging her the same as she was edging me. Neither of us cumming for the longest time. Her body reacted to it, humping unconsciously against my hand for more. It was pretty hot how horny my sister could get even in her sleep.

By the time she actually got me off, it was the most wonderful flood of pleasure all through me, my body and soul aching for that release. I worried about drowning Naomi with the sudden surge of cum in her mouth, but despite it overflowing her lips again she mostly swallowed it all down without complaint.

Even though it was risky, I rubbed her clit until she came. I'd built her up enough that it was pretty quick getting her off too, and I had my little sister cumming on my fingers for the second time that night while she was cleaning up the last of my mess, other than what was drooled down her cheek.

Naomi curled into a happy ball in my lap. She tried to keep sucking on my penis, but I had to take it away from her. I wouldn't be able to stop myself if I let her go on.

Her brow furrowed in consternation as she found nothing to put back in her mouth, and I had to console her by providing my fingers. As a little treat I slowly scooped up all the cum I could find that she'd spilled and let her gradually clean herself up.

My sister was in such a deep, contented sleep by the time the movie finished that I had to gently shake her awake. Having done my best beforehand to make sure everything appeared as usual, of course.

"Wake up, sleepyhead," I said.

Naomi stretched and yawned. "Again with that nonsense?"

"What nonsense?" I asked. "You were deep asleep. You missed half the movie again. You literally drooled all over yourself. And me," I added, to cover for in case she noticed the wetness on my boxers.

Naomi wiped at her face with the back of her hand and frowned. "Circumstantial."

"Circumstantial?" I asked, disbelieving.

"Yeah. You heard me."

"I did, I just have no idea how you think that word is relevant here," I said.

Naomi knelt beside me on the couch, staring intently at me. It took a great effort of will not to let my eyes flick down to her panties. Or even to her tits, which also seemed to be drawing my gaze more than usual.

"Want to bet?" she demanded.

"Bet what?"

"That I fall asleep," she said.

"I mean... sure," I said. "But you just keep denying it, so...."

"We'll film it next time," she said. "And the watch it, and we'll see who's right. And if I win then you have to--"

"Um maybe not," I said, suddenly panicked.

Naomi frowned. "No?"

"No, I surrender."

"... weird. What got into you?" she asked curiously.

"Nothing. Just, you know, don't like to see myself on camera," I said, failing to sound nonchalant.

It wasn't quite a lie, it was just omitting details such as how much I would really, really hate to watch myself on camera while it was used as proof that I was taking advantage of my baby sister in her sleep.

I could have just not done that, I supposed, but I struggled to imagine any prize she might bestow that would be worth giving up my chance to have her asleep in my lap again so I could do what I wanted.

And that wasn't even taking into account if we proved that she did fall asleep every time, that she might take steps not to do so ever again. That would be an utter disaster, and all for the sake of winning a meaningless argument.

I'd claim I was starting to mature in my thinking, except I wasn't sure scheming to use my sister to make me cum really counted.

"You're up to something," Naomi said suspiciously.

"I'm not," I said.

"You think I don't know when you think you're being tricky?" she asked, arms folded.

"Um...."

"I'm going to figure it out," she said confidently.

I truly hoped she didn't.

****

I almost didn't do anything during our next movie night. I was paranoid that Naomi was on to me.

And she did seem to be acting like it at first, keeping her eye on me as much as the movie. But then she got comfortable next to me, and inevitably she fell asleep feeling cozy and cuddled and secure next to her big brother.

I let her just suck her thumb for a while, and then my finger. But it wasn't like I could let that go on and not desperately want her lips to be wrapped around my cock again.

So I succumbed to my desires again, despite the increased risk of doing so. She couldn't be vigilant while she was asleep, after all.

Naomi sucked me to completion in the adorable, sleepy way that she did, and I held off on making her cum until she did so, rewarding her unconscious self for the pleasure she gave me.

I did the same going forward, every chance I got. It felt less and less dangerous again as Naomi stopped thinking that I was up to something, and she kept waking up after our movie feeling amazing and relaxed. On some level we seemed to be conditioning each other.

I got stupid about it. Of course I did. I was horny and had an opportunity to push a little further, so of course I couldn't hold myself back forever.

It started out small. Slipping my fingers in my sister's panties instead of rubbing her over top of them. Her pussy was so fun to play with. So different feeling it directly, and with the added temptation of being able to put my fingers inside her.

Naomi kept reacting so well to everything. As far as I knew she didn't have any real sexual outlet other than me, so we were kind of together on getting our fun with each other one night a week. Even though she didn't strictly know that's what we were doing.

Then came an evening where she made me cum much faster than usual. I didn't know why, really. It didn't feel like anything was different. Maybe it was just the excitement in my own head because I'd been thinking of getting my little sister's panties off her entirely. Maybe just that thrill was all it took.

Since I then had time to spare, I used it.

I let Naomi keep sleeping, sucking her own thumb cozily on the couch, remnants of the taste of my cum on her tongue while she dozed obliviously. I managed to get out from under her without disturbing anything.

It was a stupid idea to actually take her panties off, since if she woke up it would be impossible to get them back on quickly and without notice. But I had to admit, all my dumbest ideas lately had also been the ones that had worked out best for me. I had no idea what lesson to take from that.

It actually wasn't that difficult getting Naomi's panties off, once I got her lying the way I wanted her anyway. I couldn't do anything with her all curled up. I needed her legs more or less straight out.

But then I had it. My sister's bare, exposed, very wet pussy.

I wasn't sure if I was surprised at how perfect and tempting it was. I was most definitely in awe though. For my sister of all people to have this effect of me, over and over in somewhat different ways. Every new discovery I made just drew me tighter in to this web of misbehaviour.

Naomi was smoothly shaved. I'd kind of known that from feeling her, but seeing it up close made it more real somehow. I couldn't really be sure why that would be the case, because if there was no boyfriend involved then it seemed like a lot of effort to maintain just for herself.

But then again I kept my pubic hair trimmed fairly close, and that was only for my own preferences. Or perhaps in case Naomi ended up waking at the wrong time one of these nights. People had their own reasons for things.

It was the cute and delicate appearance of Naomi's pussy that had me just staring in amazement and arousal for the longest time. Maybe it was just that it was my first pussy I"d seen in real life that made it so fascinating for me. It had a different impact that what I'd seen online. It was more real in significant but indescribable ways.

I ran my fingers so delicately over my sister's soft mound. I knew what she felt like, and I enjoyed it, but again it was different when I could see what I was doing. When I could freely see the soft indent my finger made as it pressed her skin, the way her pussy opened or closed just a little depending on how I touched her, the way her wetness made her glisten as I spread it over her intimate areas.

I put my tongue on her. Just the barest touch, the meagrest taste. It was only fair I do that for her. She'd been orally pleasuring me and tasting quite a bit of my flavour. I should do the same.

It was a pretense to think of it that way. Yes I could argue fairness, that I owed my sister some cums on my tongue. But the truth was I wanted to. I wanted to taste her, to lick her, to eat her. I didn't know why people made such a fuss about not wanting to do things like that. I fully had the option to do whatever I wanted, and I was excited to choose licking her out.

It was a treat for me. An extra bonus on top of what I was already getting away with. I could almost feel good about it, even if that was only in a relative sense. It was less ignoble of me to lick my sister's pussy than to have her suck my cock. At least that was what I decided in my own personal court of morality.

I was doing it anyway, justifications be damned.

Naomi whimpered and rocked her hips in small, sleeping motions as I licked her. I loved how horny she could get without even knowing it. Somehow that in itself turned me on. It made everything just that much more fun and exciting.

I had a sense by now of how she reacted and how she moved and sounded as she got closer to cumming. I'd learned that from rubbing her. I got to use that same experience as I licked her, so I had an idea how close she was.

Making Naomi cum this way was scary. Her cute, sexy noises sounded more intense than when I'd fingered her. There was more of a chance that I might wake her, I thought.

What was really bad was the idea of it was starting to turn me on more than it was scaring me. The fear of it made the thrill even higher. Some part of me wanted to see if I could make my sister cum and have her open her eyes and see me with my mouth on her pussy.

It was fucked. The consequences of doing something like that were just so not worth it. I'd lose all this fun for sure, and probably entirely ruin the relationship I had with my sister at the same time.

Yet I couldn't stop. I found myself sucking on Naomi's clit. I felt a bit like my sister in that moment with her sleeping oral fixation. I had her in my mouth, and just gently but persistently sucking on her felt right to me. It was soothing and nice along with being super hot and fun.

Naomi came for me, and I waited, heart pounding, for her to open her eyes. I felt as though she must. She made such noises and her body arched so dramatically. Even her pussy squirted me a little and made a mess, which made me perversely proud of myself.

It didn't exactly count as being good at sexy things. Naomi wasn't awake to give me that validation. But also... it had to kind of count, at least a little.

I even kind of wanted that acknowledgement from Naomi. Some stupid part of me wanted her to wake up and catch me sucking on her pussy, and even though she'd never want to be near me again to at least tell me I'd done a really good job eating her out though.

Just utter nonsense, essentially.

But I kept sucking on her anyway. Just tenderly. Enough to make my sister let out soft little coos from time to time.

I kept that up until she got too restless and the more pragmatic and intelligent part of my brain--a low bar these days to be sure--took over. I managed to get Naomi's panties back on and get us both settled again before she woke up.

"It's weird how relaxed I feel," she murmured.

"Oh?" I said.

"Yeah, do you ever feel that?" Naomi asked me. "Like... like as if just cuddling and being together kind of makes everything feel nice. Mellow. Like everything's ok."

"Sort of," I said.

I felt that way when she sucked me off, but that was hardly just cuddling. I wondered how much she'd hate it to realize that what was making her feel so good wasn't the cuddling either. Or at least that wasn't the main thing.

Naomi giggled.

"What?" I asked.

She poked her finger at my chest. "Looks like someone fell asleep and drooled all over himself," she teased.

I tugged at my shirt. It wasn't drool, it wetness from where she'd squirted on me. My baby sister was making fun of me for having her pussy all over the front of myself.

"Quite a mess," I mumbled. "Probably spilled a drink earlier or something."

Naomi laughed. "Sure, bro. I'm sure that's all it is."

I tried to shrug it off, and Naomi dropped it after teasing me a little more.

"Hey Nae, do you really feel that good from watching movies together?" I asked.

She nodded and hugged herself to me, glomming on tight. "Yeah, Max. Of course. I always did, although I'm really feeling it lately. I feel so safe and relaxed, and like it really resets all the stress I feel from other things in life."

"Ah," I said.

"Why?" she asked. "You seem weird about it."

"Well just... I don't know, what if I did something that made you feel a lot less safe?" I asked.

"Pff, silly brother," she said. "You couldn't do anything that would make me feel unsafe with you."

I groaned softly. "I think I probably could."

"Hehe, what, like you're such a bad boy all of a sudden? Mister drools all over himself while cuddling and watching movies with his sister?" Naomi gave me a terribly impish grin. "Nah, Maxxy. You could do pretty well anything. I trust you."

Her words cut me, somehow in two very different directions at once. I almost felt for a moment like maybe she'd understand if I explained what I'd been doing. If I edited myself carefully in the telling. But then again, it might crush her that much more to know the truth.

"You shouldn't say things like that to people," I said.

"Not to people. Just to my brother."

"That's...."

Naomi snuggled against me. "You get privileges other people don't."

"Um...."

"You know that, right?"

"What exactly does that mean?" I squeaked.

"Ha, damn bro, you went all red just then," Naomi laughed. "What's up with you anyway?"

"I wish I knew," I said honestly.

****

I wanted to not take advantage of my sister anymore. I really did.

But she made it so impossible for me. If she hadn't been sleeping, I would have sworn it was on purpose.

It was like I was training her unconscious self too well. If I didn't have my hand on her somewhere inappropriate, she'd slowly collapse on me more and more forcefully. Cling to me needily so that I could hardly move. Yet if I grabbed her tits, rubbed her pussy, or gave her something to suck on, she was content.

I felt like I was making that up to justify things to myself, but every bit of testing I did confirmed it. I was stuck in a position of having to grope my sister, stick my penis in her mouth, and make her cum while she slept.

An all too convenient excuse for my proclivities, really.

I did a couple more weeks that way, pretending like I was going to stop or at least slow down, letting myself be 'convinced.' The acts of a guilty person who wants to act as though they aren't as terrible as they really are.

It just felt so good with Naomi. Every single thing. And she kept coming back for more.

My sweet sister even showed up in increasingly skimpy tops and ever scantier panties. I couldn't quite work that one out, because those were decisions she made while she was quite awake. She never had any particular explanation for it either.

"It's just what's comfy," Naomi said. "Why?"

"They're just... small," I said, trying not to look at the cleavage bared by her cami or the way her panties invited one to imagine what lay just beneath.

Naomi snorted. "Are you getting uncomfortable with your sister now? I know boys get horny about anything, but I mean really."

"No no," I said unconvincingly. "Perish the thought. Just, you know, when you fall asleep against me--"

"I don't fall asleep," Naomi said.

"Sure, right, well when we sit close together anyway... there's a lot of bare skin."

Naomi clasped her hands behind her back, smirking cat-like at me. "You are uncomfortable! I knew it."

"I really wouldn't put it that way," I said desperately as I tried my best not to notice how cute and enticing she was very deliberately making herself look just then.

"I tell you what though," Naomi said. "I love you, and I want only the best for you."

"Uh huh," I croaked.

"So if you admit right now you're uncomfortable, I will go put on the baggiest pyjamas you've ever seen."

The silence hung thick for a moment. I could see the gleam in Naomi's eyes from her knowing that no matter what I said she was going to enjoy it.

"Awfully full of ourself, aren't we?" I ended up saying. "I'm amazed you think I care at all."

"No of course you don't," Naomi purred, swinging her shoulders back and forth. "Big strong brother would never be uncomfortable with his little sister. That would be silly."

"Right," I said. "Yeah. Mmhm."

Somehow we ended up on the couch with Naomi fully sitting in my lap. She was still reveling in the idea that she could make me feel inappropriate things and that I couldn't admit to any of them. Compounded of course by just how inappropriate my thoughts about her could be. Fortunately she didn't know how bad it was.

Though she might if she was going to keep sitting across my thighs like that. I could deflect a certain amount, but I was pretty sunk if she felt me get an erection beneath her. Hard to laugh that off as nothing.

I did my best to focus on the movie. It helped distract me from Naomi, at least a little. But every little shift made me aware of her all over again.

"I could see it, you know," she murmured, nuzzling against me. "When you say I fall asleep. Maybe I doze off for a moment here and there. You make it so easy to feel perfectly safe and relaxed."

"Maybe not perfectly those things," I said.

"Nah, it's true though," Naomi mumbled sleepily. "Wrap your arms around me more. I could just be...."

She may have been relaxed enough to not even finish her sentence, but I was the opposite. I was so tense. My cock was stirring, and nothing I did was stopping it. I poked her butt and winced my eyes closed, waiting for her to say something.

Then, after way too many minutes passing and me only doing my best not to move my hips or flex my cock even slightly, there came a soft snore from my sister.

Thank fuck, she'd fallen asleep before realizing her alleged safe person had gotten all horny for her. Granted knowing she was asleep only got me more turned on, since apparently I'd trained my own reactions just as much as I had hers. Sister asleep next to me--or on top of me--meant my favourite part of my week was here. My body knew that even better than my mind.
