I didn't mind Lexi hanging out in my room. I truly didn't.
Back when I'd received my first Nintendo, Mom hadn't wanted it in the living room, so I got to have it conveniently tucked in the corner of my bedroom. I'd had to let Lexi play sometimes, but it wasn't that bad. Unlike some of my friends' siblings, my little sister was generally pretty respectful of my space, and only occasionally a bit of a brat.
My setup had evolved since the early days, in consoles and tvs. The size of my screen had expanded to the point where it was genuinely comfortable to play while sprawled out on my bed. The height of luxury, given the right mood. I didn't mind Lexi emulating me there either, lounging on my bed like it was her own while she played either with me or by herself. Even using my room while I wasn't there was fine. She'd remained a model room-guest over the years, and there'd been no change to that as she reached her late teens.
What bothered me, rather frustratingly and counter-intuitively, was that Lexi had grown up.
It happened to everyone, I supposed. I'd grown into my body ahead of Lexi, being the elder sibling and all. It wasn't like I expected her not to follow suit, albeit in a somewhat more feminine way. It was just that there had never come a time when natural barriers got thrown up to protect us from one another.
I knew Lexi was aware that she'd grown up. I saw the way she changed around her friends, around boys, around Mom and Dad, even. She acted differently, talked differently, and dressed differently.and connect to the porn site ( szaab.com ) sometimes.And yet, somehow, she thought nothing of bouncing into my room on a Saturday morning in her sleep shirt and panties and flopping onto my bed while firing up whatever game had her attention at the moment.
Sleep outfits were often the worst offenders of all her outfits, since they nearly always lacked proper bottoms. Skirts could be just as bad, though, or tight jeans or shorts, or tops that either hugged her too well or not well enough.
I honestly, truly tried my very best not to look at her that way. I made a very conscious effort. But in spite of my best efforts, there were only so many times I could wake up to her casual state of partial undress before I had to acknowledge that yes, in fact, my sister's butt looked pretty good, and was just as interesting to stare at as if she hadn't been my sister.
Following from there, naturally, was the forced acknowledgement that Lexi possessed all the other physical attributes an eighteen year old girl generally does, all the same interesting-to-stare-at kind of bits. Bits I really wished didn't look quite so good on my sister.
Lexi was cheerfully oblivious to my problems, which was infuriating at times. I could almost think that she was doing it on purpose, showing off her butt to me just for fun, but that wasn't like her. She'd never, to my knowledge, deliberately teased me with her body. I didn't think it even occurred to her that she could.
And so, once again, I woke up one Saturday morning to the shifting of my bed as Lexi got all comfy, lying down facing toward the tv and away from me. She was quiet about it, had muted the tv and everything, but she couldn't help disturbing the mattress as she lay down on her tummy. Not for the first time I wondered if there might have been subtle benefits to having a narrower bed, if only so I wouldn't wake up to her butt in my face, and all associated problems..
I feigned sleep for a while. I didn't have to get up yet, and I didn't much want to either, partly because I had some inconvenient morning wood. Not because of Lexi, but just because.
Unfortunately for my attempts at being good, the way the two of us were lying, Lexi's butt was directly in my eyeline if I opened my eyes. I could keep them closed, sure, but that was boring, and I kind of like watching her play. She'd only recently discovered Breath of the Wild, and it turned out she loved it. There was a delightful innocence of sorts to watching her explore.
"Mom's making muffins," Lexi said. "They might be ready by now."
I stayed quiet for a moment, then, "How'd you know I was awake?"
"The way you breathe."
"You've been listening to my breathing?"
"Kinda. Kinda can feel it through the mattress too."
"Oh you can not."
Lexi shrugged. "'K."
I sat up, leaving my covers strategically draped over my lap. "You just guessed, didn't you? You know I don't stay asleep long once you start playing."
"That's probably it." She took the opportunity of a brief lull to look over her shoulder and flash me an impish grin. "Not like I've known you for years and can tell these things."
"Not through super vibration senses. Or whatever."
"Doesn't take super senses. Just takes some basic awareness."
Lexi was back at her game, eyes glued to the screen once again. I let the argument drop. I didn't really know if she was telling the truth or not. There was just enough believability in what she said to make it confusing. On the other hand, I couldn't remember her ever correctly calling me out on being awake without checking before. But on the other other hand, how many chances did I give her? Not many.
I was happy enough to be distracted from my mental circling by watching her play. Then a little less happy when I was further distracted by what she was wearing. Her top was riding up a bit, leaving a gap between it and her panties. Her lower back was uncovered. Not strictly arousing on its own, but rather by proximity and potential. And she did have such beautiful soft skin...
I reached over and tugged Lexi's top down. It only halfway covered her panties even after my adjustment, but it was better. She gave me a lopsided grin for my troubles.
"What was that for?"
"What was what?" I asked, electing to plead ignorance.
"You just pulled a 'Mom'."
"Nuh uh."
"Yuh huh. She's always fiddling with my outfits too."
"That's not what I was doing. Your shirt was riding up. That's all."
"So you fiddled with it."
"I fixed it."
Lexi nodded sagely. "That's what Mom calls it too."
I frowned, but she didn't glance back again. I opted not to carry on arguing on the basis that I'd only get myself in trouble. Pointing out that I wasn't acting like Mom at all because Mom wouldn't have been fascinated by the small of Lexi's back seemed like a bad move.
Just to make things more difficult, Lexi shifted during a lull in the action and her top rode up again, more or less where it had been to start with. What ever happened to the days when it was all baggy shirts at bedtime? When did these smaller, cuter tops start making such an appearance? Oversized t-shirts wouldn't ride up like that.
Aaannnd now I was thinking like Dad. Fantastic.
I should probably have just given up then. I could have just walked out, left Lexi to her game, and gone to check on those muffins she'd mentioned. That wasn't what I decided to do.
Instead, I tickled the bottom of Lexi's foot. She squealed and kicked at me. I tickled her other foot, resulting in more kicking and protesting.
"Cut it out!"
"I'm not doing anything."
"You're tickling me. Stop!"
I stopped. That wasn't what I wanted anyway. Instead, I place my hand square on the small of Lexi's back. There was only a small strip of skin between her camisole and panties, the rest of my palm lay with the fabric of her top between us. I didn't dare go for her butt.
Lexi didn't protest my hand placement. I hadn't been sure either way, though I expected at least a questioning look or something. She ignored me entirely, to all appearances.
I was being so very stupid. I knew it, but it was one of those things I just couldn't help, despite knowing better. That small, sneaky feel of my sister. That illicit touch. It was the tactile equivalent of all those times she'd made me stare at her butt. It got to me the same way, made me feel things that weren't at all proper for a brother.
"What ya doing now?" Lexi asked.
"Nothin'."
"Nothin'?"
"Yeah."
"Huh."
And still she didn't tell me to move my hand, nor even glance over her shoulder at me. Just kept playing. Letting me leave my hand on her back. Though, I supposed, it wasn't really objectionable yet. Since she couldn't see into my mind, all she knew was that I had a hand on her back. Odd, but not yet fully weird or worthy of argument.
It made me question myself though. Why I was doing any of this. Yes Lexi had a nice butt. Yes I'd been forced to acknowledge that thanks to her lack of awareness around me. Yes she had lots of other interesting qualities too. And yes it felt nice just having my hand there, resting, drawing her warmth through my palm. And... and...
I shook my head, having rather lost my train of thought somewhere back there. I needed to snap out of it. It was early, that was all. Not thinking straight.
"I'm gonna go check on those muffins," I said.
"Good idea. Bring me one if they're ready?"
She beamed such an innocent, hopeful smile that I could hardly refuse. I amended my earlier thought about how she didn't realize what she did to me. In certain specific ways, she certainly did. How hopeless would I be if she ever explored beyond adorable, impossible-to-resist smiles?
I threw on a shirt and headed to the kitchen. I could smell fresh-out-of-the-oven baked goodness even before I got there.
"Morning, Aiden," Mom said. She was just setting the last of a tray of muffins onto a cooling rack. She smiled. "You do have a sense about these things, don't you?"
"It's why I get up every morning."
I gave her a kiss on the cheek in passing, then snagged a couple small plates from the cupboard.
"Are you taking one to your sister?"
I nodded. "Yeah. She's in my room. Probably not coming out for a while."
Mom chuckled softly. "Where else? I don't understand that girl. She never wanted a Nintendo of her own, you know. Never in all these years."
"I think she's just clever and realizes she doesn't need to spend money or presents on a setup of her own when she can just use mine, and maybe pick up a few games here and there that she wants to play."
"Probably so," Mom agreed. "When you take those up, ask her if she wants some juice?"
"I'm not room service," I grumbled.
Lexi hadn't moved since I'd left her. She might as well have been frozen in time, if not for the progress she'd made on screen.
"Thanks, bro," she said with another beaming smile as I set her muffin next to her.
"No crumbs," I warned her.
"No worries. I'll sweep 'em all on the floor."
"That's not at all what I said."
"Mmhm," she replied absently while carefully breaking off a bit of muffin and popping it in her mouth. "Ow! Hot!"
"Yeah, doofus. Just came out of the oven."
"'oo din' tell me 'at."
I sighed dramatically. "Yeah, my bad. You want juice?"
"'es p'ease!"
I shook my head and made my way back to the kitchen. Mom already had two glasses of juice sitting on the counter, though she'd disappeared in the interim. I scooped up the glasses and escorted them back to my room. Apparently I was room service this morning whether I wanted to be or not.
Lexi took a long drink of her juice upon delivery, then paid me with yet another angelic smile. "Thanks."
I sat and watched her play for a bit while we both ate our muffins. It was easier not to stare at things I shouldn't when I had food to distract me, so that was nice. Once I'd finished eating, I ran into trouble again.
Another muffin would have been good. I probably should have grabbed two to start with anyway. But that would require some small amount of motivation, and I was already comfortable, and Lexi's cami had pulled up again...
There was a solid band of skin between the bottom of her shirt and the top of her panties. Wider even then when I'd tried to fix it before. Like she was doing it on purpose. I watched her carefully for a moment, but I still didn't think it actually was deliberate. Just careless. Totally unconcerned around me, for some reason.
Well, not for some reason. Because I was her brother, and she assumed she could trust me not to perv on her. I felt horrible that she wasn't correct in that assumption. And yet, somehow, not horrible enough to look away.
Since I'd already gone for it before, and it hadn't worked out too badly, I was quicker this time to scoot close to Lexi and put my hand on the small of her back.
"You want another muffin or anything?" I asked, just to pretend to myself like I would take an excuse not to feel up my little sister.
"No," said Lexi in an absent tone. "I'm good."
She was good. I had my hand on her back, not quite on her butt, and she could have sent me away if she wanted. But she was good. Interesting.
I rubbed a small circle over her lower back, partly directly on her skin, partly through the thin material of her camisole. Still no reaction. I carried on with another circle, then just kept going. Maybe I could spin it as just giving her a back rub if confronted, which in a sense was exactly what I was doing, so I had the technical truth on my side. But that was only if I was confronted, and thus far she didn't seem to have any interest in such a thing.
My low-key, impromptu back rub continued, gradually expanding its radius of influence. I made sure not to actively grab her butt at any point, though my pinkie strayed across the line of her panties more than once.
It was both fascinating and confusing that Lexi was just letting me do it. It was possible, I supposed, that it might just feel nice. Strictly speaking, back rubs didn't have to be weird or sexual. Maybe she was genuinely enjoying it and didn't realize I might have less wholesome motives.
I truly didn't know how far I was prepared to push it, and luckily I didn't have to find out. Our dad called for me, interrupting my pervy, daydreamy back rubbing.
"Aiden! Are you in your room?"
I jerked my hand away from Lexi, then tried to play it off like I hadn't been caught in the cookie jar, so to speak.
"Yeah, Dad," I called back. "What's up?"
"Can you come help me with something?"
"Ok. Give me a minute, I'll be right out."
My heart pounded a little too fast in my chest. It wasn't like I'd been caught or anything. Dad hadn't even come to my room. But I'd been doing something I shouldn't, and it could easily have gone worse.
"Guess that's the end of that back rub, huh?" Lexi said.
"Uh, yeah, I guess so."
"That's too bad. It was kinda nice."
I stared at her, but she didn't even glance my way. Her tone was utterly lacking in guile or sarcasm. So far as I could tell, she meant exactly what she'd said. Which was, after all, what my hope had been. Something didn't sit quite right with me about it, but I didn't have time to worry about it right now.
"Keep your eyes on your game," I said.
"Why?"
"Gotta change, don't I? You heard Dad."
"So what, you thought I'd peek?"
"Maybe. I dunno. Just keep your eyes averted, yeah?"
Lexi snickered. "You're being so weird this morning. When have I ever looked?"
"I dunno. Just don't start now."
I was pretty quick about getting dressed, and it was really only a few seconds while I changed boxers that mattered anyway. I rarely slept in anything more than underwear, and what with Lexi's early morning gaming, she'd seen me like that too many times for it to even register.
She was still just lying there staring fixedly at the tv screen when I left.
****
I was pretty convinced I'd been temporarily insane that morning. Once I'd gone through some of my normal life, the urges I'd felt seemed ridiculous and not a good idea to act on at all. Then again, that was often how urges experienced while horny seemed once the moment had passed.
Luckily, I hadn't broken anything. Nothing had changed. I'd acted a bit weird, but judging by Lexi's lack of reaction through the rest of the day, she'd barely given it any thought.
It was late that evening before I was given any sign that I'd made an impression.
This time, I was the one playing a game. Lexi came into my room near-silently, except for the faint squeak of the door. I didn't give her much notice at first since that morning was out of my mind, I was otherwise absorbed, and her walking in whenever she wanted wasn't unusual, so long as I hadn't left the door fully closed. She was better than our parents about respecting a shut door, and I made sure to leave it cracked most of the time so as not to push my luck and ruin a good thing.
Rather curiously for Lexi, she slipped around behind my chair and stood leaning against the back of it, arms draped loosely around my neck. When she didn't do anything more than that, I got too curious not to say anything.
"What ya doing there?"
"Nothin'."
"Nothin', huh?"
"Yep."
"You trying to freak me out just hovering like that? You know I'm not gonna give up and let you play instead just because you're being weird."
"Perish the thought." Lexi shifted slightly. "No, I had a thought like maybe I could rub your shoulders or something, but it's not a very good angle. Then it turned out it's kind of a comfy spot."
"Comfy, or just amusing because you're lurking behind me?"
"Both." She moved her chin closer to my ear. "It was kinda weird you just rubbing my back out of nowhere, you know."
My heart jumped. She didn't sound like she knew exactly why I'd done it, but she was being a bit hard to read too. "Oh?"
"But it was nice."
"Oh. Good."
"So I thought it might be nice if I did something for you too."
"Really? Is that what this is?"
"I dunno. It was a thought. People like shoulder rubs, I think. I never saw the appeal really. Back rubs just seem better. Mighta been a good chance to find out for sure, though."
"Well I mean if back rubs are on the table..."
"Can't do that either, smarty-pants."
"Maybe not right here, but I possess the mystical power of locomotion."
I slid smoothly out of my seat and onto my bed without ever taking my eyes off my game. I emulated Lexi's favourite game-playing pose by resting on my tummy with my elbows propping me up near the very foot of the mattress.
"Wow," Lexi said with all due sarcasm, "that's a neat trick."
"I thought you'd like it."
"Buuuttt what if I just steal your chair now that you're out of it?"
"That would be cruel, and I would be forced to be slightly annoyed at you."
"Oh. Well then."
Lexi seemed to still consider being a chair thief for a moment, but opted against it. She came over to sit with me instead.
She was once again in my blind spot. I could feel her, but couldn't see her without craning my neck around. I was forced to consider whether I'd made an error in playing along. Having her so close to me and not being able to see what she was doing did some very weird things to my imagination.
Somehow, Lexi's first move was not something I ever would have guessed. She shifted around, disturbing the mattress under me with her movements, then swung a leg over me and sat down straddling my butt.
"The hell are you doing?"
"What?" Lexi wiggled a bit, then settled in. "Seemed easier this way."
"What seemed easier?."
Her hands landed on my back. "This."
Lexi started rubbing the small of my back, slowly working up my spine. Admittedly, sitting right on top of me allowed for a remarkably even pressure distribution, but I still wasn't sold on it.
"I really don't think you needed to sit on me for this," I said.
"Of course I didn't need to. I chose to. I opted to. But no, I didn't need to." Lexi pressed more firmly, approaching more of a massage than a simple rub. "Or are you not enjoying it?"
"No I mean it's nice, definitely."
"Good." Lexi ran her thumbs all the way up my spine, then spread her fingers and dragged her hands back down. "It's supposed to be nice."
"And you're just gonna keep sitting on me?"
"Yep."
"Fair enough."
I couldn't really complain too hard about Lexi being weird. I'd started it that morning. There was no arguing that. And it genuinely was pretty nice getting a casual back rub while chilling together. Even better, it almost certainly meant she hadn't taken my morning weirdness as being anything to worry about. She wouldn't be reciprocating otherwise.
For a time, it was all good. Great, even. Getting to hang out and game like I'd wanted to anyway, but with the added bonus of getting a thorough, if unfocused, back rub. I only had to start questioning everything again when Lexi slipped her hands under my shirt.
"Ooh, you're really tense," Lexi said. "I couldn't feel that before."
I declined to mention that I'd only tensed up specifically because she'd gone under my shirt. I had enough to deal with trying to figure out why she'd done so.
There was a reasonable chance this was some kind of slow-played payback. That maybe she knew my intentions had been somewhat less than honourable when I'd rubbed her back, and she was getting some kind of revenge now. Or, on a more hopeful note, maybe she was just messing around, emulating me on the assumption that I'd been doing likewise. Or it could even be something like she genuinely was just rubbing my back and thought that my shirt was interfering.
It was so hard to know what to do when I couldn't tell what Lexi was thinking. So I did nothing. It seemed safest.
She kept right on going. My shirt got pushed up further and further to the point where I lifted myself and let her roll it right up to my shoulders. I wasn't sure that was wise, but I was really kind of getting into it. As long as I ignored the question of her motives, it was extraordinarily pleasant.
I got so accepting of Lexi's back rub that I let it soothe and relax me, and let all my concerns about it drop away into the background. I was also rather unprepared for her suddenly hopping off me and exiting the room. I watched the doorway for a moment in case she was coming back, but it remained empty. I bemusedly tugged my shirt back into place and carried on by myself. Even though that had been my initial intent, it wasn't quite the same anymore.
****
Lexi returned as normal the next morning like nothing had happened. She snuck in and settled in on my bed on her tummy, wearing only panties and what appeared to be the same cami top as yesterday morning. She got Zelda going, and was soon fully absorbed in it.
I was glad things hadn't changed, but I also would have liked if she'd worn pants. Even a more modest pair of panties would have been nice. The ones she wore this morning were smaller and silkier than I was used to seeing on her, molding to her butt and not covering nearly enough of it to keep me from checking her out.
I feigned dozing for a while, using the time to stare at my sister's tight ass. Not a healthy or helpful option, but it was what it was.
Eventually, if only to stop my own perving, I stretched and carefully extricated myself from my covers, which was somewhat tricky just because of how Lexi was pinning them down on one side. I cunningly hid my morning boner by lying on my tummy next to her and watching her game.
"I was wondering when you were gonna move," she said.
"When I woke up."
"You've been awake for a while."
"Not this again."
"Look, dude, I know when you're awake. It's not a big deal."
"Bah, get out of here with your witchcraft."
"Shan't."
I shrugged, conceding defeat. "Fair enough."
I laid where I was, agonizing over the knowledge that my erection was unlikely to go down if I kept it pressed against the mattress, nor indeed if I kept lying so close to Lexi. Subtly grinding my hips both helped and didn't, for different reasons.
There really wasn't much chance of me staying good forever under the circumstances. I definitely couldn't just start massaging Lexi while fully erect though. That was insane far beyond even the boundaries I'd already pushed. I slipped out of bed and made my way to the bathroom, keeping my back to my sister until I was out of sight.
Upon my return I was in a much better state, still kind of horny, but on a much more manageable level, and without a telltale erection to give me away. I tried to play it cool as I positioned myself next to Lexi again and lowered a hand to her back.
Neither of us said anything as I rubbed small circles, then up and down Lexi's spine. I casually rubbed her back like it was no big deal, like it was something we'd always done.
I took a cue from Lexi and slowly pushed her top up, exposing more bare skin above her panties. I didn't dare push it quite as far as she had mine, but I got plenty of warm, smooth skin under my palm and fingers, and still she didn't say a word about it.
I half wished she'd balk, just a little. Just enough to keep me in line. Because as it was, I wasn't sure I could stop. There was something truly fascinating about touching my sister like this. In an ostensibly innocent way, that in reality was nothing of the sort. I felt guilty that she didn't know what was going on in my head, but not quite guilty enough to stop on my own.
It was one of those times when I should maybe have been more careful what I wished for. Although, admittedly, it was entirely my own damn fault.
It was a stupid move. No way around it. I was just horny enough to be an idiot, take things that little bit too far, and very nearly ruin everything. In this case, all it took was grabbing Lexi's butt.
Her facade of ignoring me dropped immediately, and she whirled her face around toward me, lips frozen in a shocked gasp. I stared at her for a long few seconds, still cupping her ass, then jerked away.
"Sorry! Sorry. Shit, sorry. Fuck."
"Aiden?"
Her voice was a mix of surprise and confusion. I didn't dare look right at her again. I stood up, facing away from her, very much wishing I'd thought to get dressed before now. Standing in my underwear was not making the moment any easier.
"I know, I shouldn't have done that," I said. "That was my bad. Totally. I really... I just... I'm sorry."
"Well you don't have to freak out that bad about it," Lexi said.
I almost smiled at the gentle chastisement, but wasn't ready for that yet. "I don't?"
"No. You caught my surprise, mostly. I didn't really think you'd do it." She paused. "But after yesterday... I kinda knew it was a possibility you'd do something like that."
I cautiously turned to face her. She'd paused her game and was sitting up cross-legged.
"You knew?" I asked.
"Kinda. I suspected. But, like, I didn't think I was right."
"And you didn't say anything?"
"I told you. I didn't think I was reading it right." Lexi shrugged. "And if I was, I kinda wanted to see what you'd do."
"Well, uh, I'm kinda confused now, then."
Lexi chewed her lip thoughtfully. She studied me with big, searching eyes. "You know, all those times I saw you looking at me... I thought it was just looking."
"Well-"
"I thought there's no way you'd be looking the way other boys do."
I flushed, fully ashamed of myself. "'Cause I'm your brother."
"Yes, partly that. But, like, I didn't think you saw me that way. Didn't think it occurred to you." She waved a hand at me. "Always being topless. Changing around me and stuff."
I looked down at my almost-naked body. "Wait, really?"
"Well duh."
"But... but... it's my room! You're the one always coming in wearing hardly anything."
"'Cause you hardly wear anything. I thought it was fine."
"So did I."
"Yeah?"
"Yeah."
"Good."
"Fine."
We both stopped for a second.
"I can't tell if we're still arguing," I said.
"Were we arguing?"
"I can't tell that either."
Lexi nodded. "Fair."
I looked down at myself again. "I'm gonna put on a shirt."
"Also fair."
I threw a shirt on, then sat down next to Lexi, but not too close. I still wasn't sure where we stood.
"So, this is a whole thing, huh?" Lexi said.
"Seems so." I tilted my head slightly. "Was my lack of clothes really a problem?"
"Not a problem, exactly. But it made me look sometimes. And made me feel things I didn't necessarily want to, you know?"
I nodded. "Oh boy do I know."
Lexi smiled slyly. "You were totally checking me out too, huh?"
"Constantly. Some days, it was like you wanted me to look at your butt."
She giggled softly. "I really didn't think you'd care. You know, 'cause you didn't care about what you wore around me. I liked being able to wear whatever around you. It was kinda fun."
"Fun?"
"Well, you know, a little naughty, but not in a way that would really mean anything." She shrugged. "But I guess I was wrong about that one."
"Yeah. Kinda." I shrugged back. "But then, I guess I got it pretty wrong too."
"Yeah."
"Yeah." I scratched my head. "So, uh, what do we do now?"
"You're asking me?"
"I am. I was really hoping you had something."
"Not so much."
"Alas."
I took a moment to consider our position. Somehow when I imagined disaster scenarios, or scenarios where nothing went horribly wrong, this particular set of circumstances never came up. I was unprepared for a reality where Lexi and I both felt some inappropriate things for one another.
"Well," I said slowly, "I guess we probably need to start by wearing more clothes around each other."
"Oh. Yeah, that makes sense."
"And the back rubs weren't ever a good idea."
"Probably not."
"And maybe first thing in the morning visits aren't so great."
Lexi nodded with reluctant acceptance. "'Cause of your boners."
"What?"
"What? Isn't that why?"
"Partly, yes. But that shouldn't be your reason. You weren't supposed to see them."
"I mostly didn't when you were awake. But I've come in often enough when you've got a little tent going under your blankets." Lexi grinned crookedly. "That's part of how I know when you're awake, actually. You shift a little to hide your erection."
"Oh."
"Yeah."
"Well then." I coughed awkwardly. "I didn't know that either."
Lexi shrugged. "If it helps any, they never really mattered one way or the other to me."
"They didn't?"
"Nah. I know it happens to boys. And I knew for sure they weren't over me, 'cause of how you were asleep and all."
"True."
"Although... actually no."
"What?"
"Nothing."
"No come on, what were you going to say?"
Lexi had gone a bit red. Her sudden reluctance and shyness really made me want to know what she could possibly have cut herself off from saying.
"It's kinda bad," she said.
"So?" I spread my arms. "So is this whole morning."
"Ok. Yeah. Fine. I just, like, I sometimes thought about maybe... touching it."
I sat back a little. "Oh."
"I didn't or anything. Just thought about it. Just 'cause it was there."
"Yeah, no, I get it."
"That's not too weird?"
"Lexi, I grabbed your butt. I didn't just think about it, I did it." I shrugged. "So no, you're not any weirder than me."
She nodded. "Ok."
"Which is not to say that either of us should be having these thoughts in the first place."
"That's the problem alright." Lexi sighed heavily. "So... pants time, I guess? For both of us?"
"Um... yeah, that's probably a good idea."
"Yeah. Probably is."
Lexi left to go get changed. I tried to resist the urge for one last peek, but still snuck a glance at her butt before she was out the door.
What an emotional mess this all was.
But at least we could be responsible adults about it. We could behave ourselves and dress and act properly, even if we'd needed a little nudge to remind ourselves of it.
****
As prim and proper as our behaviour was over the next week, which was to say adequately so, something didn't feel right about it to me. Lexi and I made sure to always be dressed around each other, the same as we would around anyone else. We also lapsed into polite formality at times when speaking to each other, though that had more to do with trying to crack each other up than anything else.
It took a few days for me to realize that I just wasn't seeing as much of her. She was still around, still present at meals and stuff, but not in the same way. She didn't, for instance, come to my room hardly at all except for one evening when she asked if she could come in and play a game. I didn't think about it at the time, but that might have been the first time in years that she'd actually asked instead of just wandering in and claiming my setup if I wasn't already using it.
I thought about talking to Lexi about our situation again a few times, but didn't quite work up to it. We still needed time to settle, or whatever, and technically things were going the way we wanted them to. Kinda. Sorta.
It took me by surprise when I woke up the next Saturday and found Lexi lying in my bed, playing Zelda in her shirt and panties like nothing had changed. I briefly considered the idea that I'd traveled backward in time somehow, then concluded that was insane. I blamed my sleepy brain.
"You forgot pants," I said.
Lexi didn't hesitate even slightly. "You forgot a shirt."
"I was sleeping."
"Yeah. Without a shirt."
"I'm in bed. This is how I sleep. I thought I was going to be alone."
"Why would you think that?"
"Because... you haven't been around as much."
"Yeah. And that sucked." Lexi shrugged. "So I'm here again."
"In your underwear."
"An' a shirt. I remembered mine."
"Thank goodness for that," I muttered. I shifted a bit so I could see the tv screen. It didn't distract me from Lexi's butt nearly enough, but it was an attempt. I was trying. "You know you're gonna make me stare."
"Not making you do anything. Tempting, perhaps."
"You're... are you doing it on purpose."
Lexi sighed. "No, not really. I just... I got up, and I really wanted to come play Zelda. Then I was just outside when I remembered that I wasn't s'posed to come in without pants. I didn't want to turn around and have to come back again."
"It's not that long a journey."
"No, but, like, it sucks, Aiden."
"Walking?"
Lexi paused her game and half turned around toward me. "This, Aiden. This whole thing with us. I felt all week like I couldn't just come in anymore. I didn't like that feeling."
"You still can. Anytime. Just... with pants on."
"Yeah. Not the same, though."
I blinked slowly. "That's a deal breaker for you?"
"It's a symbol."
"A symbol?"
"Of our self-oppression."
"Um..."
"And I mostly really didn't want to go back for them."
"Again, not that long a walk."
"More of an emotional trial than a physical one."
"Huh?"
Lexi tilted her head and made direct eye contact. "If I turned around, I might not have come back."
"Oh. Is it that bad?"
"I dunno. Kinda. I never ever felt like I couldn't be in here before. Never felt like there was a problem between us. I don't like it."
"Yeah. Me either."
Lexi chewed her lip and fidgeted a moment. "So, like, an amnesty morning? Or something?"
"I don't feel like I've been given much of a choice."
"You could kick me out."
I shook my head. "Never."
"Good."
Lexi went back to her game. I went back to staring at her butt. Somehow, I wasn't entirely convinced we'd made the correct decision.
I eventually sat up, mainly just because it made it harder for me to absently check out my sister. She glanced at me as I rose, then turned away again when I stopped making such a disturbance.
"You're welcome to get dressed if you want," Lexi said.
"I have to even though you don't? Not hardly fair."
"You don't have to. Just saying you could."
"Well... not just yet."
"No?" Lexi was quiet a moment, then giggled to herself. "Oh, right, morning wood, huh?"
I flushed slightly. "It's not that funny."
"It's a little funny, though. I mean, boners, right?"
"That's what constitutes humour for you?"
"Sometimes."
"You must be so popular with the boys."
Lexi gave me a funny look. "Did you just call me a slut?"
"What? No! Because of the, you know, laughing at dicks. And such."
"Uh huh."
"You know that's what I meant. Don't be difficult about it."
"You're right, I do." Lexi grinned at me. "See what I mean about it being funny?"
I rolled my eyes, but she was already looking away again. As revenge, without really thinking it properly through, I smacked her butt. Just a quick, light slap.
Lexi gasped in indignation. She fixed me with an accusing glare, but I met her gaze neutrally and serenely.
"Rude!" she said.
"Or is it funny?"
"Nope. Just rude."
"It seems we have some differences of opinion this morning." I slapped Lexi's butt again.
"Hey!"
"What? Amnesty morning, right?"
"That's not how that works."
"Isn't it?"
"It isn't."
"Oh." I raised my hand yet again, but Lexi swung her fist and connected solidly with my thigh before I could spank her. "Ow!"
"Amnesty morning," she said calmly as I rubbed my leg where she'd hit it.
"Now who's abusing it?"
"Both of us, I guess."
I continued to rub my leg, though it honestly didn't hurt after the initial jab. It was an excuse to keep my hand to myself, which wasn't the worst thing. In spite of my playfulness about it, I had genuine concerns about Lexi's attitude this morning, and indeed my own possible reactions.
The flip side was that I was happy to have her back. It didn't feel right always waking up undisturbed, no scantily clad sister-butt to guilt over. Didn't feel normal. That was probably a sad indictment of my life, in some respects, but it was what it was.
Just to see what would happen, I slowly moved my hand toward Lexi again. I didn't go for more spanks or anything, but rather simply set my hand on her back. Just let it lie there, gentle and unassuming.
"You're kinda pushing it," Lexi said.
"I know."
"I might have to go get dressed."
"You say that like it's a threat, even though it's exactly what I wanted this whole time."
"Is it, though?"
"Yes."
Lexi gave me a disbelieving glance, only for a second. I knew I wasn't making a compelling argument at the moment, but it genuinely wasn't my fault she'd shown up in her shirt and panties this morning.
I moved my hand just a little, drawing the smallest of circles with it. I rubbed in gradually broader strokes, waiting for a reaction from Lexi. It was unclear even to me why I was pushing my luck like this. Why I would risk it. But then, it was unclear too why she'd returned without being properly dressed. There was probably some truth to the explanation she'd given, but I couldn't imagine it was the whole truth.
I pushed Lexi's shirt up her back, baring the lower half of it to be rubbed directly. She bit her lip very noticeably, but didn't turn or say anything. Just let me massage her.
Once I'd started, I couldn't easily stop. Regardless of what my original goal had been, either in theory or reality, I was sucked in by something much less than innocent. Lexi's warm skin under my fingers, so silky smooth to my caresses. The subtle tensing and relaxing of her muscles, the small, barely audible gasp I caught only because I was listening for something, anything.
I grew even bolder, far too daring for my own comfort, really, but being horny could do that to me. I moved to my knees, swinging one leg over Lexi to straddle her and get a better angle. My erection was all the more prominent from that position, and I was careful not to drop too low and poke her with it. I really hoped she wouldn't turn around, which was probably a good indicator that I should stop.
Instead, I kept pushing. I rubbed Lexi's back with both hands, sliding her shirt incrementally further up toward her shoulders. It was barely covering anything, though since she was on her tummy, she wasn't actually indecent or exposed. Kind of.
Her panties looked even smaller, tighter, and less appropriate with so much of a gap. Nothing but bare skin to either side; long, stretched out legs one way, the soft line of her spine the other. Her butt tempted me more than ever, barely covered and so easy to reach.
I resisted a little longer, but only a little. In spite of the further trouble I expected it to cause, I couldn't control myself for ever. I swooped both hands downward in synch, grabbing firm handfuls of her ass and holding there just for a moment. I moved away again, back up to her shoulders, still awaiting a delayed reaction that just wasn't coming.
She wasn't going to say anything? Interesting.
Lexi was very clearly aware of what I was doing. She couldn't possibly miss it. Plus there was the tension in her muscles, and the way she stared a little too fixedly at her game. She was deliberately hiding her reactions as best she could, but wasn't entirely succeeding. Her efforts only made me want to try harder and get something out of her, even though any word from her was as likely to put an end to the fun as anything.
Nothing about it was strictly rational. Nothing at all.
I rubbed Lexi's back, taking incrementally longer and longer breaks to fondle her bum. I grew daring enough to venture along to the sides of her breasts as well. If she hadn't been lying on them, I might have gone even further.
"Aiden?"
I paused, hands halfway onto Lexi's butt. I slid them a down a little more and snuck in a last squeeze, just in case.
"Yeah?"
"I think I'm gonna go grab breakfast now."
"Oh."
Lexi turned her game off, wiggled out from under me, and fixed her shirt as she sat up. She grinned crookedly at me, and as I looked down at myself, I belatedly realized my cock had slipped out the front hole of my boxers at some point without me noticing.
"See, you shoulda wore pants," Lexi said gently. She reached over and calmly tucked my erection back into my underwear for me.
"That, uh..."
"Must be very embarrassing having your penis fall out like that."
Lexi gave my cock a squeeze through my boxers, then kissed me on the cheek. I stayed frozen, kneeling right where I was, but followed her with my eyes until she was out of the room. She stayed long enough to put her controller away and turn off the tv, then padded out without so much as a glance my way, but the smallest, most knowing of smiles on her lips.
After she was gone, it still took a few moments for me to shake myself into action. First thing was to stumble over to my door and make sure it was firmly closed. Next thing, drop the boxers. Then, naturally, fall back into bed naked and horny, and wrap my hand around my hard, pulsing cock.
Lexi's brief, soft touch was fresh on my skin and in my head. She'd grabbed my cock so decisively I couldn't have managed a protest if I'd wanted to, and being honest, I really wouldn't have wanted to.
My head was full of my sister as I jerked off in me bed where she'd been lying so shortly ago. I thought of her scantily clad body, the way she felt, how she'd let me play with her.
I wanted more. I wanted her hand wrapped around my cock again, to feel her stroking me. That brief touch had been such a tease.
It was so easy to imagine Lexi doing more. To picture her sneaking back in, kneeling next to me in just her panties, giving me a look of mock disapproval even as she reached for my cock. I so badly wanted to let her jerk me off. Thinking about what it would feel like just wasn't the same as experiencing it. Not even close.
The door opened while I was still lost in my incestuous daydream. I hadn't been listening for anyone approaching, and usually I could at least expect a knock first, even if it was the classic parental knock where they didn't give me enough time to hide whatever I was doing before opening the door.
Lexi poked her head in a mere fraction of a second after I'd pulled my blanket over my lower half. Her eyes flicked toward my hastily covered erection, but I didn't think she could see it. Not that it mattered. She knew what I'd been up to. Along with her having already seen my cock slip out, me covering myself wasn't accomplishing a hell of a lot.
"Mom wants you to come down," Lexi said in a professionally casual tone. "We're all gonna have breakfast together."
"We are? Why?"
"Dunno. Just telling you what she said."
"Uh..."
"Should I tell her you're busy?"
I glared at Lexi. "No, you ass. Just... ugh."
A smile escaped her otherwise perfectly controlled lips. "Shoulda jerked off faaasteeerrr," she said in a sing songy voice.
"Not helping."
"I know. But it's fun."
"Well can you just, like, let me get dressed then?"
"Yeah, I guess I could." Lexi grinned even wider. "Don't take too long, or I'll be back."
"I believe you would, too," I muttered as she left.
Jamming my cock into a pair of pants really sucked. It sucked even more trying to arrange it somehow so my boner wasn't obvious. But it was necessary, thanks to my darling sister. In more ways than one, even.
I made it through breakfast ok. I started out eating fast and without tasting much of anything, with the idea that I could escape again as soon as possible, but that didn't work very well. Lexi and I kept meeting each other's gaze. That was all it took. Knowing what she knew, being reminded of it several times a minute, none of that was helpful. I softened somewhat, but not entirely, thanks to her presence.
It got worse toward the end because Lexi started giving me deliberate little smiles. I didn't know exactly what they meant, but the uncertainty didn't help any, it just made me imagine possibilities.
I escaped back to my room afterward. I wasn't quite as horny as before, but still felt the urge to jerk off. It wasn't quite clear whether I should bother or not, given that I was all dressed and everything now, but I was leaning toward doing it anyway. Luckily I still had my pants on when Lexi popped by again.
"You're going to make me think you're trying to catch me with my pants off," I said.
"Maybe stop taking 'em off then?" Lexi replied with a casual shrug.
"You want me to masturbate with my pants still on?"
"Hey, man, that's all up to you. I have nothing to do with that."
"You kinda do, actually."
Lexi grinned crookedly. "Perv."
"Did you need something?"
"Nah. Not really. Guess I should probably give you some, uh, alone time, huh?"
"That'd be nice."
"Hell, maybe I should go play with myself too."
My cock twitched at the thought of my sister with her hand down her panties. "Maybe you should."
"After all, someone wouldn't stop feeling me up this morning."
"Well-"
"Kinda gets to me after a while, you know?"
"Yes. I think I do."
"I bet."
"Well have fun."
"Yeah. You too, I guess."
I began questioning what had just happened after Lexi was gone. It all seemed pretty straightforward, in one way, but in another I couldn't quite reconcile that we were both, presumably, about to masturbate while thinking about each other. Unless she was just teasing or something, which was possible. I, certainly, was going to jerk off to my sister. Whether she did or not was up to her.
It was an odd state of affairs, at any rate.
****
My only other questionable interaction with Lexi that day-as if more were needed-came that evening. I was, initially, watching a movie with Mom and Dad. Or, rather, I was watching, Mom was flitting back and forth doing other things and asking me what happened while she was gone, and Dad was fighting his evening battle with falling asleep in his chair. Generally a losing battle, as it was this time.
So despite there being three of us ostensibly watching, I was the only one to take note when Lexi slipped in to join us. I didn't think anything of it at first. She just sat and behaved herself, rather deflecting my attention away again.
Lexi crept closer on the couch with such small, sneaky movements that even though I caught the individual shifts, she was practically right next to me before I realized that she had a purpose in mind. I gave her a curious look, but she stared evenly straight ahead at the tv until I gave up. I knew she was looking when she thought I wasn't, but I didn't challenge her on it.
She leaned in against me, just gently, not with her full weight. I said nothing. I remained mute when her hand crept up to my head and she started running her fingers through my hair.
It might just have been her version of carrying on whatever it was we'd been up to that morning. Maybe it was just something she felt like doing. I couldn't imagine it was totally innocent, not with the context of what had been going on between us, but I wasn't yet convinced that it was anything I needed to stop. It didn't hurt that it felt really nice having her play with my hair.
"You sure you wanna be this close when Mom comes back?" I whispered.
"Why wouldn't I be?" Lexi whispered back. "M'not doing anything wrong."
"Sure, but this isn't something you normally do either."
"So what? It's cute."
"Is it? Not suspicious, you don't think?"
I was forced to concede, however, that judging by Mom's expression when she came back in, Lexi and I probably did look cute together. Outwardly innocent too, it seemed. Good enough.
Lexi stuck around and cuddled for a while, then flounced off again on some schedule known only to her. Maybe she'd just been trying it out or something. Testing the water on being subtly naughty when it wasn't just the two of us.
****
I smiled to myself the next morning upon waking up with Lexi next to me. Her bare legs were the first things I saw, meaning that she hadn't done a damn thing about dressing more appropriately. That was fine.
The hell with everything else; it was fun first thing on a weekend morning. If she was gonna keep coming in like that, I was going to enjoy it.
I rolled onto my back and closed my eyes again. I reached a hand out to my sister's calf and gently ran it up and down her lower leg. That was all I did for a while, other than listen to her play, as she'd turned the volume up once I'd awakened.
As I allowed myself a slow, lazy waking up process, I gradually scooted my way to where I could let my hand travel up Lexi's thigh, and eventually her butt. She didn't outwardly react as I fondled her ass, not that I'd expected her to.
It was only when I finally sat up and took a full look at Lexi that I realized her panties were, in fact, the only clothing she had on at all.
"Where the hell's your shirt?"
Lexi shrugged "Where's yours?"
"You know I don't sleep with one."
"I do. So why should I wear one if you aren't gonna?"
"You're a girl."
"Good catch."
"You have boobs."
"You can't see 'em."
It was true, in a technical kind of way. Since she was lying on her tummy, I couldn't actually see her tits, other than the barest hint of side boob. Still, though.
"What about when you want to leave?" I asked.
"Dunno, really. Guess we'll figure that out at some point."
I didn't really believe that Lexi had nothing in mind. She wouldn't have just walked in topless without some kind of plan or agenda.
Her top was on the floor by the bed, as I belatedly spied. So she hadn't come from her room like that, and she could probably reach it and slip it on without me actually seeing much of anything. Although I could 'accidentally' kick it out of reach, if I wanted. That was a thought.
"Pretty soon you're not gonna be wearing anything at all," I said as I ran my hand up Lexi's bare back.
"And wouldn't you love that."
"I might."
"You would."
I grinned and grabbed her ass. "Ok, I would."
"So I really couldn't do that."
"No?"
"No. Look at how handsy you get when I'm just lying here being good."
"Excuse me? Good?"
Lexi stuck her tongue out at me over her shoulder. "Yes, good. Not now, obviously, but most of the time." She turned to face front again. "I can only imagine what you'd try if I was lying here naked."
A thrill ran through me at the thought of it. I shook my head to try and clear it, which didn't really work.
I shifted again, moving to straddle Lexi as I had the day before. I rubbed her back with both hands, going slow and firm like I was professionally massaging her. Though, rather unprofessionally, I snuck little feels of her side boob as I ran my hands over her soft skin.
"I can't believe you'd think such things of your own brother," I said.
"Oh you can believe it."
"So harsh."
"Fair as can be, dude."
"I guess we'll just have to see about that, won't we?"
Lexi tensed beneath me. "We will?"
"Yes. For science."
I slipped my fingers into Lexi's panties with the intent of pulling them down. She reached back and gave one of my intruding hands a vicious slap.
"None of that, now," she said.
"Ow. Not nice."
"You're trying to steal my panties."
"Well... yeah."
I grumbled to myself and went back to massaging Lexi, while she in turn went back to pretending to ignore my decreasingly subtle groping of her ass and the sides of her tits. I tried pulling her panties down a few more time, but got slapped again with unerring accuracy.
If I really wanted to, I could strip Lexi anyway. If she truly had to fight me off, she'd have to roll over, and in that case I'd be in a no-lose kind of scenario. That wouldn't be right, though. If she wanted her underwear left on, then on it would stay.
Mine however...
My heart sped up as I slipped my boxers off. This was very nearly as risky as stripping Lexi, and without any of the immediate feedback from her that would have let me stop before committing.
I was so hard, and precum was leaking from my erect cock. I looked down at my sister, so very nearly naked below me. She was entirely right about the things I might want to do to her, under the right circumstances. She tempted me so badly.
I had no idea if Lexi knew that I was naked or not. She hadn't looked, so far as I'd seen, but she might well have guessed what I was up to, since I'd been squirming around awkwardly behind her. She hadn't said anything, though.
Either way, I was going to try. Just to see what I could get away with. I rubbed Lexi's back, returning to my regular pattern, carefully keeping my cock away from her at first. It wasn't easy.
Slowly, so slowly, I lowered myself until I was just pressing against her butt. She tensed at the feel of my cock, though I still didn't know whether or not she knew it was free of any covering. I didn't get slapped, at any rate.
I kept rubbing her, getting her back to a relaxed state before sitting down more firmly. I wedged my cock between us, sitting it firmly in the faint cleft in the middle of her panties. That made her tense right back up, of course, but by proceeding slowly I kept things more or less balanced out.
Although, really, in spite of her tension, I couldn't say for sure that I wasn't doing exactly the sort of thing she expected me to. It was unclear which of us was in control of the situation, if indeed either of us were.
I rocked my hips ever so gently, testing her reaction. She didn't say anything about it or swat at me, which was encouraging.
It felt really nice grinding on Lexi's butt. I was glad she wasn't stopping me, because once I'd started I really didn't want to quit. I rubbed my cock back and forth, sliding on the smooth material of her panties, slowly pushing them deeper into her butt crack.
Lexi was actually getting better at ignoring me the longer I went. Possibly she just couldn't help
