Keywords:inc,fic,erotic,hot Leif burst into his sister's room, filled with the sort of petty rage that only a sibling could inspire. Celia had their shared laptop in front of her on her bed. She remained totally engrossed in the screen despite his abrupt entry. "I don't know what's worse," Leif muttered aloud. "That you always manage to sneak off with the computer when I need it, or that it's always so you can watch porn." Celia only barely glanced at him. Earbuds trailed from her ears down to the laptop, and her hand moved slowly, but rhythmically between her legs. "Close the door," she said. "I'm not closing the door, dammit." Leif marched over, flipped the laptop shut, then grabbed it away before Celia could stop him. "Honestly. Some big sister you are." "Hey!" Celia pulled out her earbuds and scrambled after Leif as he walked away. She beat him to the door and physically blocked it. "Come on, that's mean. I was busy." "Yes. I know. I saw." Leif's eyes flicked downward. "I can still see, for that matter." Celia flushed and tugged her shirt down more firmly over her panties, which only helped her modesty a little, given that she had nothing else on below the waist. "I let you jerk off whenever you want," she said sulkily. Leif flushed in turn. "At least I wait until nighttime. Not middle of the afternoon." "Well we can't both use the computer at bedtime, can we?" Leif met Celia's gaze. They stared each other down for a tense several seconds. "I got school stuff to do," he said. "Yeah, well-" "Can't you just look stuff up on your phone or something?" Celia frowned. "The screen's so small. And then I gotta use one of my hands just to hold it, and-" Leif threw his spare hand up between them. "Really don't want to know any details. I'm sorry I brought it up." He tried to slip past Celia, but she was quick enough to block him. He was at a disadvantage since he was holding the laptop, and she was only half dressed and had just been fingering herself. He didn't want to get too physical under the circumstances. "Ten more minutes?" Celia said. "No." "Come on. You can wait just a little bit." "I could. But it sets a bad precedent. And besides, you weren't even that into it yet. It'd take you way longer than ten minutes." Celia grinned impishly. "You know that much about how I masturbate, do you?" Leif went even darker red. "Unfortunately, yes." "Hm, does that mean you've been watching me?" "No, just-" "Maybe the reason you always need the computer when I have it is you want an excuse to-" "Nope!" "-come in and-" "Stop!" "-see a little-" Leif thrust the laptop toward Celia. "Good god. Take the damn computer! Just stop talking." Celia beamed wider as she accepted the laptop back. "I'm right though, aren't I?" "Cel, seriously, shut up." Celia leaned in and kissed Leif on the cheek. "I'll be quick, promise." "Yeah, yeah. If I don't see the laptop in twenty minutes, I'm coming back, and I'm not going to be so accommodating." "Uh huh. Looking for another excuse already, I see." "I... you... shut the hell up." Celia laughed as she bounced back to her bed and opened the laptop back up. Leif shook his head and slammed her door on his way out. He really shouldn't have to put up with shit like that, he felt. Catching her masturbating should make her more uncomfortable than him. That was only right. And yet, Celia was Celia. She was just weird. **** It was nearing twenty-five minutes later when Celia popped into Leif's room, laptop in hand. He hadn't been able to muster up enough righteous irritation to march into her den of sin a second time, so he was glad she hadn't gone even further over his time limit than that. "Here you are," she said in a sing-songy voice. "One laptop for important school work." "Great," Leif said with a roll of his eyes. "Thanks ever so much." "You're welcome." Leif cringed slightly as he opened the computer up, but Celia had been good and cleaned up whatever porn she'd been watching beforehand. He was just starting to settle in and open up the stuff he needed when she bounced onto his bed beside him. He examined her out of the corner of his eye, deciding whether he needed to chastise her some more. At least she'd put pants on. That was something. "Can I help you?" Leif asked. Celia shrugged. "I thought you might want help, actually." "Me?" "Yeah. You're doing homework or something, right? Well, I've been through all those classes already. Maybe I could make it easier." "You want to do my homework?" "No, no. Just help. If you want." Leif narrowed his eyes and considered. "Are you feeling guilty?" "I wouldn't go that far." "You are too, aren't you." Leif chuckled. "Alright, fine. How 'bout you get us a snack or something then. We'll see how it goes." Celia flipped her hair over her shoulder, bit her lip, then nodded. "Yeah, alright." She flounced off, and Leif got back to his work for a while. His respite didn't last long. Celia returned with a bowl of popcorn, fresh from the microwave. She settled in next to him, propping their snack between them. "So what are we doing?" Celia asked. "I hope it's not physics. I was never any good at that stuff." Leif rolled his eyes. "You don't need to be involved at all if you don't want to." "No, I said I'd help." "Yes, but-" Celia jabbed her finger at the screen. "Hey, Napoleon. I know that guy. History, is it?" Leif sighed. "Yes, it's history. Got an essay due tomorrow." "Ah. So it wasn't really an emergency. You just procrastinated." "Like you never do." "Oh I totally do. Everyone does." Celia shrugged. "But if you'd planned better, you wouldn't have had to interrupt me." "Can we please not talk about you playing with yourself anymore?" "Hey, you brought it up." "What? No I didn't. That was you. Literally, like, twenty seconds ago." Celia grinned and popped some popcorn into her mouth. "Oh yeah." Despite his sister's 'help,' Leif got some progress made on his assignment. Enough that he was confident he'd be finished by sometime that evening. Celia went quiet for a while, which went mostly unnoticed by Leif as he typed away. She lay on her back and gazed thoughtfully at nothing. "Hey, Lee, can I ask you something?" Celia said. Leif shrugged without taking his eyes off the screen. "I don't see why not." "I'm not ugly, right?" Leif turned his head to stare at Celia, hardly blinking for several seconds. "What?" "I mean, I don't think I am." "Then why ask?" Celia wriggled uncomfortably. "'Cause you'd tell me if there was something weird about me, yeah?" "Everything's weird about you." "No, for real, though." Leif ran a hand through his hair. "No, Cel, nothing's weird about you. Not physically. Mentally, you might want to get checked out." "You're sure?" "'Course I'm sure. I've seen way more of you than I ever wanted to. I think I'd know." Celia sat up. She chewed on her lip a moment. "What about my tits?" "What do you..." Leif trailed off. Celia had pulled her shirt up, and was holding it above her breasts. "Like, they aren't weird either, right?" "I..." "I know my left's a tiny little bit smaller than my right, but you can hardly even notice, really." Leif shook his head, snapping his eyes shut to block out his sister's bare chest. "Dammit, Cel. Put your boobs away." "Ok, but-" "Now!" Leif peeked out through lidded eyes, then opened them fully when he saw that Celia had complied. "The hell's the matter with you?" "You wouldn't have looked if I hadn't tricked you." "You say that like it's a good excuse." "Not 'good' exactly, but yeah. An excuse. Or a reason, actually." Leif closed the laptop and pushed it aside. "Ok, listen, you better tell me what the hell's going on here. That, or I'ma have to seriously kick you out." Celia twirled some of her hair nervously around her finger. "Yeah, fair enough." Leif waited a moment. "So?" She shrugged. "It's not that simple." "Ugh. Just tell me why you felt the need to flash me just now. I mean, come on, Cel." "I needed to know, ok? I'm trying to figure out if something's actually wrong with me." "But why? Why would you suddenly think there's something wrong? And, more importantly, why ask me? Why not, like, Brian maybe?" Celia's face clouded at the mention of her boyfriend's name. Leif, in turn, frowned in puzzlement at the reaction. "We're, uh, not together anymore," Celia said while studiously examining Leif's bed sheets. "Oh." "Yeah." "Since when?" Celia shrugged. "Couple days." "And it's, like, definitely over?" "Yeah. Pretty much definitely." "Shit." Leif coughed awkwardly. "So you're, uh, feeling insecure now? Or something like that?" "Well... kinda. I tried not to be. Brian said some pretty mean things at the end. They've kinda stuck with me. I know he was just trying to hurt me, but... you know." "Christ. Ok, seriously, forget what he said. You're right. It was all just to hurt you." Celia laughed bitterly. "Not that easy, unfortunately." "No, I guess not. But I really do think he's full of shit, for whatever that's worth." Celia managed a shy smile. "For real?" "Yeah. For real." "Even my tits?" Leif groaned. "Ugh, fine. Show me them again." Celia lifted her shirt, and this time Leif looked at her breasts deliberately. He tried to ignore his sister's face and pretend he was just being shown some random boobies. In that context, it would have been quite an enjoyable assignment. As it was, he was still decidedly unsure about it. "Yeah, they're good," he said. "Good?" "You've got nice tits, Cel. Promise. Put your shirt down." Celia slowly lowered her top and smoothed it out. "Not weird or anything?" "No. Perfectly lovely, I assure you. I'd be praising whatever gods were listening if you weren't, like... you know... my sister." "Yeah, sorry about that." Celia brushed some of her hair back coyly. "I know it's kinda awkward for you. But hey. Boobs are boobs, right?" "In a sense, sure. Buuuttt... sister boobs are still different." "Have it your way." Celia hopped off the bed. "Maybe I'll let you get back to it, then." "That'd be nice of you." "Try not to let the thought of sister boobies distract you." Leif stared after her long after she'd left the room. Thanks to her parting shot, he couldn't think of anything except her breasts. "Goddammit," he muttered. **** Leif spent the evening regretting his decisions. He regretted them while finishing his homework, through supper, and afterward. It had seemed like the right way to proceed at the time. But now... Celia was annoyingly chipper. She'd catch his eye at times and give him a quick wink, which he found insufferable. She knew he was thinking about her chest, and it was all her fault. It wasn't right. Leif spent some time before bed sulkily playing video games in the living room, since at least they distracted him from images of the forbidden tits. His parents seemed to recognize that he wasn't in a good mood, even if they didn't have any idea what had actually occurred. At least, he very much hoped they didn't. They left him alone, at any rate. His sister, however, didn't want to take a hint. Celia came in and sat down on the far end of the couch. She pulled her legs up half-curled so that her feet just barely infringed on his half of their shared seat. "Whatcha doin'?" Celia asked. "Is that a serious question?" "No, not really. Wanna play something together?" Leif sighed. "Not really." "Oh." She chewed on her lip. "Are you mad at me?" "A little, yeah." "Just because I-" "Well don't say it." Leif glanced around, but he didn't see any sign of their parents. "I mean, come on. No one else needs to know." "Mom and Dad are sitting outside drinking wine. We're fine." Celia leaned in closer. "I can talk about my boobies if I want." "Cel..." "Boobies boobies boobies!" Leif glared at her. "I swear to god. If you-" "Boobies!" Celia grinned broadly, her expression slightly manic as her eyes dared him to do something about it. "Why are you like this?" Leif asked. "I mean, seriously." "Like what?" "All weird about stuff." Leif rubbed his face. "It's been bad recently. And today especially." Celia looked slightly hurt. "You know why. I told you." "Yeah, Brian, I know. But, like, that doesn't explain everything. It doesn't explain why you're shoving your boobs in my face yet again." Celia looked down at herself. As she leaned forward, she displayed an inappropriate amount of cleavage. She examined her situation, then shrugged. "That really wasn't on purpose. Not this time." "Ah, right. Well that's ok then." Leif went back to his video game. Celia slumped back against her corner of the couch. She pouted for a few minutes before speaking again. "So you didn't actually like my tits at all, did you?" she said. "Oh for fuck's sake, Cel." "You were just trying to make me feel better." "Yes, of course I was trying to make you feel better. But I wasn't lying. Your tits are fine. Good. Lovely, even. They're just... you're just..." "Your sister?" "Yeah. That." "So you're trying to tell me you'd like my tits, except they kinda gross you out?" "No!" "'Cause it sounds like-" "I haven't been able to stop thinking about them, ok? I mean, it's your fault. But just... ugh. Like, that's not what I want in my head." Celia arched an eyebrow. "You're still thinking about them?" "Yeah. I was distracting myself pretty well until you showed up again." "Oh." She considered, then sat back with a satisfied smile. "Good." "Good?" "Yes. Good." "You're a jerk." "No, I'm insecure. There's a difference." "You can't be that insecure." "Why not?" Leif saved his game and closed it out. He wasn't going to be getting anywhere at this rate. "You know what I think?" "What?" "I think you just want an ego boost." "Yeah. That's what I've been saying." "No. You've been saying you think your body's all weird, 'cause of what your ex said. I think you know it isn't, but you really want someone else to tell you that, and for some reason you've picked me." "Well... maybe." "So cut it out, dammit." Celia folded her arms. "Or what?" "Or... I'll be annoyed, I guess." They stared each other down for a moment, then Celia smirked and slowly reached for the bottom of her shirt. Leif grabbed her wrists and restrained her movements. "No," Leif said. "I wasn't gonna do it." Celia squirmed and tried to get free. "You're so paranoid." "It's not paranoia if you've already done it, and were just about to do so again. That's just called learning." "Hmph. Whatever." Celia jerked her arms again, and this time Leif let her go. "I really wasn't gonna do it again, though. Once was enough." "Twice." "Yeah, right. Twice was enough." "You're so damn weird." Leif got up and started walking out of the room. "Hey, Lee?" Celia said in a soft voice. "Yeah?" "You were right. I did just want someone to tell me what I already knew." "Thought so." "Sorry for being weird." Leif shrugged uncomfortably. "That's ok. I mean, honestly, I probably shouldn't be complaining about seeing tits. It's not like girls are typically lining up to show me their boobies." "No. They probably aren't." Celia bit her lip. "If you want-" "Please don't finish that sentence." "It wasn't-" "Don't care. Don't wanna hear it. Night, Cel." "Yeah, ok. Night, Lee." **** Leif began to relax over the next few days. Celia didn't flash him again, and she managed to be subtler about her 'computer time' too. He still had confusing images of her in his head, but he could deal with it. He was less impressed when Celia invited her friend Kara over on the weekend, and the two of them hung out in the backyard suntanning. It had never much bothered him seeing his sister in a bikini before, but the context was different this time. Rather unfortunately, Leif's mom, Cindy, caught him watching the girls out the window. She came to the wrong conclusion, but it was still rather embarrassing. "You know," Cindy said, "I'm sure they wouldn't mind if you went outside too." Leif jumped and turned around guiltily. "What?" "I'm sure Kara would prefer it to you staring at her through the window," she continued, giving him a meaningful look. Leif wanted to protest, but what he'd actually been thinking was worse. He couldn't very well explain to his mother that he was staring at his sister in her skimpy outfit rather than her friend. "Well, I-" Cindy gave Leif a gentle, but quite firm, push toward the door. "Outside with you. Girls prefer you try talking rather than just peeping from a distance. It'll be good practice." "Mom! Come on. It's not even like that. And Kara wouldn't-" "That's why I said practice. It'll be good for you one way or another." Rather awkwardly and miserably, Leif shuffled outside and over to where the girls were hanging out. Neither seemed to mind his approach, although they did pause their conversation when he got within earshot. "Hey," Leif said. "What's going on?" Celia shrugged. "Not much. Gettin' some sun." "Wanna tan with us?" Kara asked with a teasing smile. "I think Cel's got a spare swimsuit." Leif was a bit slow on the uptake, what with his mind being a bit preoccupied, but he belatedly shook his head. "No, that's ok." Kara frowned slightly. "What's up? You seem a little out of it." "I kinda am." Leif slumped down onto the end of Celia's lounger. "Maybe didn't get enough sleep," he fibbed. "Uh huh. Sure," Celia said. She peered at him suspiciously, even as Kara continued to appear concerned. "No, really, I'm fine," Leif said. "I might just chill out here for a while, if that's ok." He shrank a bit as he continued to be assailed by the steady gazes of both girls, but Celia finally leaned back and closed her eyes. "Yeah, whatever. That's all we're doing anyway." Kara nodded slowly. "Yeah. Just chilling. Hey, Cel?" "Yeah?" "Mind grabbing me some water?" Celia groaned. "Can't you get it yourself?" "I could, but I'm invoking guest privileges." "You're a lazy bitch is what you are." "Oh really? Well... maybe you're right. But maybe I also know what you-" Celia bounced to her feet. "Fine, fine. I'll get you some damn water." "I was just going to say-" "Well don't." Celia marched away, still grumbling to herself. Leif made a conscious effort not to watch her ass as it swayed beneath her bikini bottoms. He didn't need any mental comparisons between it and her boobs running around the mess his head already was. "What was that about?" he asked, partly to distract himself. "Oh, nothing," Kara said airily in the sort of way that suggested the exact opposite. "Nothing, huh?" "Weeelll... maybe I wanted a chance to talk to you." "Dare I ask why?" Kara glanced toward the house, ensuring they were alone, then leaned forward conspiratorially. "I saw you watching us," she said. "Until your mom kicked you out." Leif tensed. "Oh. Sorry. I, uh, you know..." He shrugged helplessly. "It's a weird time, right now." "Yeah, I bet." Kara pursed her lips in thought. "Now the real question is who were you actually watching?" Leif flushed warmly and turned his head away in what he hoped was a nonchalant manner, but probably wasn't. "What?" "Cel's been saying some stuff, and-" "What kind of stuff?" Leif interrupted defensively. "What'd she say?" Kara grinned wickedly. "Nothing specific. But you're doing a good job convincing me my suspicions are true." Leif balled his fists, then let out a long, deliberate breath. "So you're gonna pick on me about it now? Is that it?" "Hell no. Well, maybe a little. But hey, it was my idea in the first place. I didn't think Cel would actually flash you or anything, but if she-" "Wait wait wait, what?" Kara shrugged. "It's a good ego boost." "It... you... the hell are you saying?" "Chill, little dude. All I'm saying is Cel needed some compliments and reassurance. Why not from you?" Leif stared at Kara in total confusion and disbelief. "How is that possibly a good idea? I'm her brother." "Exactly. No ulterior motives, no chance you'll be total bastard about it. Perfect." Kara brushed her hair back and smiled coyly. "That's why I show off around the house sometimes," she said more quietly. "Works like a charm." "You... your brother... you do?" "Sure. Nothing gross or anything. Just little peeks here and there. Get him all red and embarrassed like you are right now." Kara laughed softly. "I told Cel she should flash you, partly as a joke. She was going on and on about what Brian said about her tits." She jabbed a finger at Leif. "Now that guy's a dick. Don't you ever be that way about a girl's body, no matter how annoyed you are, yeah?" "Um, yeah, sure." "We got enough problems with the media and society and porn and shit already. Don't need specific targeted insults on top of that." Leif shook his head and tried to focus. "This is so weird." "I imagine it is. But just remember, all that you have to worry about is seeing a girl-" "My sister." "Your sister, yes, but still a girl. It's not like it's anything actually bad. Relax and enjoy." Kara smirked. "You can even perv on me too, if that helps." "What was stopping me from doing that before?" "Nothing, really. But now you have permission. At least temporarily." Celia returned with Kara's water before Leif could press the argument any further. Celia handed over the glass, then scooched back into her seat while maneuvering around Leif's disconsolate form. "What'd I miss?" she asked. "Nothin' much," Kara said even as she directed a subtle wink at Leif. "Your brother says he likes my outfit." Leif startled and opened his mouth to protest the lie, but realized Kara was just teasing and it was probably preferable to the truth anyway. Plus, Celia didn't appear to believe her friend's claim. "Fine, don't tell me," Celia said. "See if I care." She settled back for some more tanning. One of her legs stretched across Leif's lap in the process. It didn't occur to him to feel awkward about it until he caught Kara's smirk. He rolled his eyes at her, but couldn't do much more than that without making things even more uncomfortable. **** Leif knocked on Celia's door that evening and waited for a response before entering. He slowly pushed the door open, making sure his sister was fully clad before walking in and closing it behind him. "Hey," Celia said. She was lying on her bed, laptop open in front of her. "You looking for the computer?" Leif shook his head. "No. You can have it for the evening, if you want." "I mean, sure, I'll keep it if you don't want it. I've basically finished with it for now, though, if you wanted a turn." Leif sighed. "You mean you just finished watching porn again?" "Basically, yeah." "I wish you'd try and hide that stuff better." "I know. I like how uncomfortable you get, is the thing. It's adorable." "Yeah. About that." Leif sat down on the edge of Celia's bed. She rolled on her side and propped her head up on her hand. "What's up?" Celia asked. "I had a talk with Kara earlier. Or, rather, she had a talk with me." "What about?" "You. Obviously. All this stuff you do..." Leif waved his hand in a vague circle. "Is it really all just to get a reaction from me? Are things that desperate?" Celia bit chewed her lip as she considered the question. "I wouldn't say desperate, exactly. I mean, flashing you kinda was. I'll admit that." "And all the times you 'accidentally' let me catch you... doing things?" "That mostly wasn't on purpose. Mostly. Not at first anyway." Celia had the grace to look slightly guilty, though still not as guilty as she should have been. "I was kinda embarrassed the first time you, uh, walked in on me. 'Cept you were even more embarrassed than I was, and that was kinda funny." "Hilarious," Leif said dryly. "Then, I dunno, I just stopped worrying about it. I know it's supposed to be a whole thing, not wanting anyone to catch you playing with yourself, but I honestly didn't mind. And it was still good for a chuckle sometimes." "Uh huh." Celia scratched her chin, then continued. "I guess recently... I kinda have been looking for something more. You know, like a li'l ego boost." "Yeah, I got that." "I know you like to act like you hate it, but I didn't think you'd mind. Not really." Celia peered intently at Leif. "Do you?" Leif was suddenly at a bit of a loss. It was a good question, actually. Did he mind? On the surface, yes. She was his sister, and she was acting totally inappropriate around him. But was that how he truly felt, or just how he thought he should feel? "I mean... it's not that big a deal, I guess," Leif said. "I wish you'd be more discreet, is all." "I know. But I probably won't be. I really like not having to hide who I am from you." Celia tilted her head. "You know, other than Kara, I'm probably more honest with you than anyone. That's kinda strange, isn't it? But still nice, I think." "Um... maybe?" Celia giggled. "I know, you still think I'm a weirdo. That's ok. I kinda am." Leif broke a smile and chuckled softly along with her. "You definitely are." A slightly awkward silence descended afterward. Leif shuffled from foot to foot and glanced toward the door. "Guess I should get going," he said. "You could hang out," Celia offered. "Yeah, I could. I'm not sure that's a good idea right now." She gave him a look. "Dude, I'm not gonna do anything. I haven't ever since I flashed you, right?" "No, that's true." Celia patted the bed next to her. "Come on. Let's watch a movie or something." Leif hesitated, then started walking forward. "Yeah, ok." He was a bit tense as he got comfortable next to Celia, but that gradually faded. Her total ease helped him get over some of what he was feeling. "What do ya wanna watch?" Celia asked. "I dunno. It was your idea." "Yeah, but I don't want to put on anything you won't be interested in." Leif shrugged. "I'll only be half paying attention anyway." "Ok, fair enough." Celia nudged him with her shoulder. "I'ma get you chilled out again sooner or later. Just you watch." "I really hope you do." As Celia got the movie started, Leif let his whirling thoughts take over. He only stared in the general direction of the laptop, eyes unfocused, totally absorbed in his own emotions. Weirdly, Celia's proximity actually helped. Even though she was the primary cause of his anxieties, she was also a soothing presence. He didn't protest when she pulled him closer and made him cuddle against her shoulder. He relaxed into it, letting her warm softness and subtle scent lull him into a feeling of security. Time passed in a pleasant and confusing haze. Leif was dimly aware of the sound and flicker emanating from the laptop, but far more aware of every little thing about his sister. She seemed enraptured by the movie, but still took the time to hold him and toy with his hair. Her breaths caused just the slightest brush of her breasts against him. Leif truly had no idea how he'd let himself get seduced into this comfy snuggling. It seemed like the last thing he should have allowed, and yet here he was, enjoying himself. He closed his eyes for a time and pretended he was elsewhere, dreaming of a more suitable scenario. "Hey," Celia whispered. "You still awake?" Leif cracked his eyes open again. "Yeah. Just thinking." "Still?" Celia gave a crooked smile. "I was tryin' to get you to stop that for a bit." "I know. It's kinda working." "Yeah?" "Yeah." Leif tried to pull away a little, but Celia pulled him right back to her even more firmly. "I haven't figured out why I'm letting you." "'Cause it's nice?" "Well, yeah, but that's not enough. Not right now. Not with... you know." Celia ruffled his hair. "You silly. It's still just me. Just your big sis." "Kinda. I guess. Mostly." She kissed his cheek. "Totally," she said softly. "Always will be." "Yeah?" "Yeah." Leif faced her, studying her expression intently. She seemed faintly amused, and maybe just a little antsy for some reason. He couldn't figure out why until she leaned in and kissed him again, this time pressing her lips directly onto his. "Cel..." he mumbled around her mouth. "Shhh." "Don't." Celia ignored him. Her lips were too soft and inviting for him to pull away. He needed her to stop, but she wouldn't. Leif found himself kissing back, pressing more insistently against her. She made a small growl into his mouth, then rolled halfway on top of him. Her breasts pillowed on his chest, her hair fell ticklishly around his face. There was a brief pause for breath. Celia pulled away fractionally, just enough to get their mouths of out each other's way. Her eyes were wide and searching, waiting for some clue from Leif's expression. That was his moment, he knew. If he wanted to stop, he had to say it then. He had the words, they were ready, but they caught in his throat. He didn't want to stop. They made out some more, the intensity evening out to a slower, gentler tempo. Leif moved a hand to his sister's tits, she slid one of hers under his shirt. Only Celia stretching her leg and accidentally kicking the laptop to the floor shattered the moment. Both her and Leif went stiff and alert at the sound of the crash, then sagged into a flurry of nervous giggling. "Well shit," Celia said as she crawled to the edge of her bed and scooped the computer back up. "Guess I should have seen that coming." "Is it ok?" Leif asked. "I think so. Movie's still running." "Ah, well. Good then." Celia flipped the laptop closed. There was a moment of silence between them. "I didn't mean for that to happen, you know," she said quietly. "Yeah, I know." Leif toyed with a loose thread on his shirt. "It wasn't bad, though." Celia smiled crookedly. "No, it wasn't." "Please just tell me it wasn't one of Kara's suggestions." Celia shook her head. "No. I don't think even she'd go that far." "But we did." "Yes. We did." Celia chewed on her lip for a moment. "I don't know where it came from. I mean I do, but I don't. You know?" "Kinda, yeah." Leif gazed at his sister's cleavage. He'd both seen and felt her tits now. Oddly, if anything, he was less uncomfortable about it now that he'd had a feel. He had no idea why. "You're not gonna tell Kara, right? Or anyone?" "I'm... not sure. I definitely won't if you don't want me to. I usually tell her most stuff, though. And I might need to talk to you more if you don't want me telling her." Celia pushed back her hair from her face. "You might not believe this, but I really have no idea what to think of... all that. The stuff we just did." Leif breathed a sigh of relief. "Good. Then it's not just me." "It definitely isn't." After another small pause, Celia leaned in and kissed Leif softly again, just a brush of their lips. He swallowed hard as she pulled away. "Stop that," he said weakly. "I should, shouldn't I?" "It's... you know... like..." Leif faltered altogether as his sister's face moved closer. He gave in and met her halfway. They fell together onto the bed, him somewhat on top of her this time. He slipped a hand under her shirt, exploring her suddenly fascinating skin as he sought out a more intimate connection with her breasts. She ran a hand over his lower back, then down further to grab his butt. They writhed together, Leif grinding against Celia as his cock grew hard and needy in his pants. He was going crazy for his own sister. He needed to be close to her in a way that didn't make sense, and that he never, ever had before. "I really need to go," Leif mumbled around her frantic kissing. "Mmhm." "No, for real, though." "I know." Celia rolled on top of him, and he let it happen. She felt so good, so soft and inviting. Her shirt was hitched halfway up, exposing most of her bare tummy to his caresses. Leif surrendered to her enthusiasm for the next little while. He let things happen and stopped trying to half-heartedly slip away. Every kiss, every feel, every small pressure on his uncomfortably hard cock made him happy to be right where he was. That was enough. They finally broke apart one last time. Celia rolled onto her back without breaking eye contact. Her face was flushed, her eyes shining with lust, her mouth open in a soft pant. Leif felt much the same as she looked. "I should be careful," she murmured. "I could get used to that." "That's the last thing we need." "Don't I know it." Celia bit her lip. "I really should let you go. But, like, thanks for that. I think I needed it." Leif frowned in confusion. "You needed it?" "Yeah. Just, for like, feeling normal and shit." "That was about as far from normal as-" Celia waved her hand. "Yeah yeah, I know how that sounds. It made sense in my head." She shrugged. "I dunno. I thought I was over it. Then we were cuddling together, and it felt nice not being alone, and it's you..." "Yes, me. Your brother. Remember?" "I do. You still kiss like a boy, though." Leif shook his head. "Oh good lord." "Well you do. And it can just be... just what it is. Right?" "I don't know how to answer that." "Fair enough." Celia glanced at the laptop. "Hey, you want the computer? 'Cause I kinda want to use it again, but it'd really be only fair if you wanted a turn." Leif was pretty sure she was planning on masturbating again. He actually would have liked a chance to look up some porn and get off, but he didn't want to admit it. Not that she wouldn't be able to guess. "No, you keep it," he said. "You sure?" "Yeah. I'll be fine." "Ok, thanks." Celia grinned. "A parting gift, then." "A wha-" Leif stopped short as Celia lifted her shirt, exposing her beautiful breasts to him. He knew better what to expect this time, and was over some of his knee-jerk uneasiness. He drank in the sight, storing it away for his imminent play time. "Something to help out," she said quietly. He managed to smile and nod. "Yeah. I guess so." He reached forward and gently cupped one of her tits, just for a moment. "Still amazing." "Amazing, eh? I might have to keep flashing you if my tits get better every time." "I think I might be ok with that." Celia's return smile was wide and genuine. "Good." **** In fact, Leif's next few evenings' sessions involved many images of his sister, mostly of her boobs. Other than that, there was also just the memory of the way she felt, and how he imagined her totally naked. He felt a little guilty stroking himself while thinking about her, but those feelings didn't last long. She wanted him to, after all. It wasn't like he was perving without her permission or anything. Confirmation if confirmation were needed, Celia interrupted Leif one weekend morning while he was lying in bed idly jerking off before he started his day. He just barely had time to cover himself up with his blanket before she burst in, but the look on her face suggested that any attempt at acting casual would be futile. "Hey," she said, cat-like grin growing all the wider as her gaze flicked down to his lap and back. It was like she could see right through his covers. Or maybe he was just too obvious. "Kara and I were thinking about going shopping today." Leif, feeling rather self-conscious, replied far more grumpily. "Yeah? So?" "So do you wanna come with?" "Why would I want to do that?" "I dunno. Just to hang out. Carry our stuff for us." Celia sat down on his bed and put her hand on his leg, dangerously close to his semi-hidden erection. "Maybe help me pick some clothes I look good in?" "That, uh..." "Or we could do some other stuff too. We don't hang out enough." "I really wish I thought you were saying that for normal reasons." "Ha, no you don't." "Yes I do." Leif squirmed a bit. "Although..." "It's tempting, right? It'd be like a date almost." "A date?!" "Well, not like that. Like a date for siblings. Who've done some stuff. But, like, I dunno. Just an innocent one." Celia flipped her hair casually over her shoulder. "I mean, Kara'll be there to chaperone, if you're worried." "I wouldn't say worried exactly." "Good. Settled." "Hang on, I absolutely didn't say that-" "Now, you better get a move on. Not that we're leaving for a bit, but if you gotta finish up here and all..." Celia winked, then flipped her top up to show off her breasts. Leif felt like he'd gone about as red as possible throughout the conversation, but his sister's easy manner and overt showing off kind of flipped things around for him. Focusing on her tits also made it harder for his embarrassment to maintain its power. "You're gonna get me addicted," he said with a hint of false irritation. Celia giggled cheerfully. "That's ok. I don't mind showing you more often if you want." "No, I bet you don't." Leif traced his fingers up her tummy and over the soft mound of her nearer breast. "You'd probably let me just, like, walk up and pull your shirt up if I wanted." She considered a moment, then nodded. "Yeah, I think I would. Not around anyone else, obviously. But then, you wouldn't do it around anyone anyway." She smiled crookedly. "I really do like the way you look at me," she said more quietly. "Makes me feel nice." "What, when I go all slack-jawed and drool like a freshly pubescent teenager?" "Give yourself more credit than that. But yeah, the way you stare." Celia wiggled a little in a mixture of self-consciousness and delight. "Getting my own brother to look at me like that. It's a hell of a thing." "How'd you put it before? I'm your brother, but I'm still a boy? Something like that." "True. Very true. And maybe it's overstating things slightly to say your motives are pure-" "Definitely overstating things." "-but I think it's fair to say your reactions are genuine." Celia glanced down to where Leif was toying with her nipple. "You make me feel sexy. Even if it's in kind of a naughty way." "Sexiness is always naughty." "You know what I mean, brother dear," she said, emphasizing 'brother' slightly. She stood and pulled her shirt down. "Anyway, you coming with us later on?" "Yeah, sure. What the hell." "Good. I'll leave you to it then." "I'm not..." Leif sighed and gave up. "Yeah, ok." **** Leif remained ambivalent about his decision even after meeting up with Kara at the mall. Partly, he simply wasn't sure he wanted to be around both her and Celia at the same time right now. Kara was the only one who had a sense that not all had remained platonic between the sibs. She didn't actually know any of the really questionable stuff, which was the only thing that allowed Leif to manage his emotions at all. He really needed to sort himself out. He couldn't go around always worrying that someone would discover he'd made out with his sister. That was a recipe for never having any mental peace again. Leif zoned out a bit as the three of them meandered through the parking lot and inside. He startled back to awareness when Kara latched onto his arm. "It's good you came along," Kara said cheerfully. "You can be my boyfriend for the day." "I... what?" Leif asked stupidly. "I mean you can carry my bags, silly," Kara said with a giggle and a teasing grin. "Why else would we ever bring boys along?" "Oh. Right." Celia, however, wasn't going to let it drop there. "Hey, he's my brother. If anything, he should be my 'boyfriend'." Kara stared at her, still with an amused expression. "Whoa there. Don't be saying that too loud." Celia grabbed Leif's other arm and started walking. "You know what I mean." "Sure I do. But other shoppers might get the wrong idea. And we wouldn't want that, would we?" Leif remained deathly quiet between the girls as they argued back and forth. He didn't care about anyone overhearing Celia call him her boyfriend. Not nearly so much as he worried that it'd clue Kara in that something wasn't quite right. Well, that and the implications for him. He and Celia definitely, definitely were not a couple. No way. She'd just been playing along. And yet, it was one of those jokes that meant something to him, even if it didn't actually mean anything at all. It was fuel for the fire of his already confuzzled brain. Things didn't get much better when the girls started browsing for clothes. They seemed to sense weakness, and made sure to keep asking him how he thought they'd look in certain skimpier outfits or underwear. Luckily, they didn't go so far as to model anything inappropriate for him. Celia took Leif aside when Kara had disappeared into a changing room to try some things on. She glanced around, then spoke in a low voice. "Hey, you doin' ok?" Leif shrugged. "I dunno. It's kinda just a lot of teasing for me right now. In my mental state and all." "Oh. Is that all." "What's that s'posed to mean?" "Exactly what it sounds like. It means I think you're being silly. We're only picking on you 'cause we love you. And 'cause it's fun." Leif gave his sister an annoyed and disbelieving look. "Yeah, that doesn't really make it better." "Sure it does." Celia looked around again, then stepped closer and pressed her lips to his. The kiss was soft, and only lasted a moment, but it was enough to stun Leif into silence. "I want you to enjoy yourself too. We'll lay off if you're really not having a good time, but just try and see the good side of it all." It was Leif's turn to glance around wildly. "You can't do that here," he hissed. "No one was watching." "You don't know that." Celia grinned and tried to move in again. Leif stopped her, holding her back while she giggled and tried to worm past his defenses. She didn't really get anywhere. Instead of continuing to try for a kiss, she slipped her hands to his waist and up under his shirt. Her gentle touch on his bare tummy was both pleasant and anxiety-inducing. He gave up and stopped fighting, finally allowing her to kiss him again on the basis that getting it out of her system might actually be the safest bet. "You know, you're acting just as weird as me today," Leif said. "Except, you know, in a different way." Celia nodded easily. "Guess I probably am." She flipped her hair back casually. "Just in that kind of mood." "Couldn't you at least wait until we got home?" Her smile widened. "You mean you want to-" "No! No, I didn't say that. Just... if you had to... like..." Celia leaned in and brushed her lips on his cheek. She whispered in his ear. "Yeah, you want to." Leif flushed warmly. The way she was pressed against him didn't help anything. Her body was becoming so damn interesting to him. It was hard to remember that she was his sister and her boobies were not meant to evoke such feelings in him. Not in public, at any rate. Kara popped back out of her changing room, which bought Leif some much needed space. Celia darted back over to her friend so they could go over the minutiae of her outfit. Leif took the opportunity to wander off and pretend to be shopping the men's section for a while. "Hey." Leif jumped slightly and whirled guiltily toward Kara, who'd managed to sneak up on him while he'd been idly browsing. "Uh, hey," he said. "What's up?" She nodded her head back toward the change rooms. "Help me for a sec?" "Uh... sure?" Leif followed Kara back to her change room, totally unsure what she could possibly need his assistance for. He was unprepared for being dragged right in with her. "No, hang on, wait," he said. "I'm not allowed in here with you." "Why not?" Kara said as she locked the door behind them. "Do you see any clothes police watching?" "No, but... I'm not, though. That's all." She gave him a look. "Whatever. Don't be a wuss. Help me with this dress, would you?" Without any more warning than that, Kara pulled off her shirt, then wiggled out of her bottoms. She still had underwear on underneath, but Leif automatically averted his eyes, only to discover that looking at the mirror in the room didn't actually help, it just gave him a different angle while she disrobed. "What are you doing?" he asked. "What does it look like?" Kara sighed. "Don't be a baby. I'm not naked or anything." "You know what I mean. You have never, ever pulled shit like this before." "Yeah, no, you're right." Kara started working herself into the dress she'd selected. "Seriously though, give me a hand, here." Leif found himself holding the dress awkwardly, then zipping up the back. He tried not to let his hands or his eyes actually touch Kara's bare skin, but there was a limit to what he could do. "So, uh, yeah," she said as she examined herself in the mirror. "Here's the thing. If you and Cel are gonna be all kissy kissy in public like that, then-" Leif went bright red. "We didn't... I wasn't... don't..." "Go on. Tell me it's a misunderstanding. I dare you." Leif stayed quiet. "Thought so," Kara said, still adjusting herself in the mirror. "What do you think? Not enough cleavage?" She shifted her boobs a bit with her hands. "I, uh... what?" "Nevermind. Anyway, I think it's good Cel's getting over Brian. All I really wanted to say is I think it's important that you consider what you're getting into." "You think I haven't? That's basically all I've been doing is thinking about this stuff." "I suspect you've been worrying more than thinking. You're a worrier." "Seems like the correct response to me." "Maybe." Kara shrugged. "You may find that just thinking about stuff without assuming all of the bad things might be more helpful, though. And I think it'd be better for Cel too. I don't want you hurting her." "Me?" Leif was so incredulous that some of his embarrassment faded instantly. "I haven't done anything. None of this is my fault." "Never said it was. I am, however, saying that your sister needs you right now. You don't need to react a certain way, I'm not saying that, but I am definitely saying that you need to consider her feelings no matter what path you choose. And I'm including this 'lack of decision' when I say make a choice. Because that's a choice all on its own, weirdly enough." "I don't know what that means." Kara gestured back toward her zipper, then started sliding back out of the dress once Leif had pulled it down for her. "It means that Cel might just want a bit of fun, or she might want more. You might just want to keep being the hapless brother caught up in some emotional nonsense, or you might want to actually step up and actively help her out, whatever she needs." "But what if she needs, like, you know..." "More kissy kissy? Or something more than that even? Then I guess that's up to you." "She's my sister. I can't do that. Not more. Not even what we've already done." Kara rolled her eyes and pulled her shirt back on. "Obviously not true. You can do whatever you want. You're both agents of your own lives." "And you think that makes it ok?" "Nothing to do with what I think. But yes, I do." Kara gave him a shy smile. "Trust me, I know what can happen." "How?" "How d'you think, dummy?" Leif's eyes widened. "You and... no, Cel said you only... but she wouldn't know if..." "Don't you be telling anyone," Kara warned him. "What me and my brother do is just for us. Got nothing to do with anyone. I wouldn't even tell you, except Cel needs you right now, and I need you to stop worrying about the wrong shit." "But how far did you-" "None of your business. For real. Just like I don't ever expect to know what you and Cel get up to. Other than kissy face stuff, obviously. 'Cause good lord, apparently that girl doesn't understand subtlety." "I knew that was a bad idea," Leif mumbled. "In a store. I mean come on." "She knows it too," Kara said. "Don't forget she's the same girl she's ever been. If she's acting out a bit, that should tell you something." "Yeah. Maybe it does. I dunno." **** Somehow, Leif had even more on his mind than before. He'd already been looking at his sister in entirely different ways thanks to their more sexually charged relationship, and Kara had dumped even more considerations on top of that. He'd already known that Celia was looking for something from him as a result of her break up, that she'd been acting weird, and that she was possibly doing things they'd both regret later. Kara had added a few twists and managed to make everything more complicated. That really wasn't what he'd been looking for. Leif didn't want to have to figure out his relationship with Celia. He wanted it to be simple and easy. The same as it ever had been. Not this emotional minefield with sporadic sexy times thrown in. Although the sexiness wasn't bad, exactly. Not unpleasant in any physical way. Just... what the hell. Leif watched Celia more closely than before. He examined her expression for clues while she rifled through racks of clothes, or sipped a drink at the food court, or even just idly perused store windows as they passed. He had no idea what he was looking for, and he sure didn't find it. It was only later, once he'd mainly stopped worrying about it, that he able to achieve some peace on the matter. He managed to slip away from the girls for a while and into the relative seclusion of a games store. It was a little more his speed anyway, and it offered very little in the way of romance, sisters, or a combination of the two. Celia still managed to find Leif and snuck up on him as he was exiting the store. She slipped right up beside him and took his hand before he could raise his defenses again. "Hey there," she said. "Gettin' tired of girly shopping, huh?" "Kinda, I guess," Leif said. "Or tired of me?" "No. I mean, not like that. Just..." Leif paused and made sure no one was close enough to easily overhear. "Kara said some stuff, and there's been stuff between us anyway, and it's all just, like, a lot." "Yeah, I know. I'm sorry about that." Celia squeezed his hand. "I appreciate everything, though. It's been really nice having you around. Doing stuff. Feeling like I'm not a total mess." "You don't need me for any of that, do you?" "I dunno. Maybe not. It's made things easier, though." Leif shrugged. They kept walking with no particular destination in mind. He found he didn't mind holding hands with Celia, though he was very conscious of it, in a low-level kind of way. "Cel?" "Yeah?" "Is this real?" "I don't know what that means." "Like, is this a weird-ass rebound that's going to end badly one way or another? Or is it for real?" Celia bit her lip. "That's not an easy question answer." "No, it isn't. But, like, nothing about this has been easy for me either. You know very well I don't know what I'm doing." "True." Celia mulled it over for a few moments. "Lee, I don't want to hurt you." "I know." "This whole thing has been pretty selfish of me." "Sure." "But I kinda, like, don't want to stop." Celia gave Leif a sidelong glance. "I know that's not really an answer." "No. It kinda isn't. But I get it." "Yeah?" "Yeah." "And you're gonna be ok?" "I think so, yeah. You're my sister." Celia frowned slightly. "What does that mean in this context?" Leif squeezed her hand. "Nothin'. Just that you are, is all." She nodded slowly. "Ok. I can work with that." **** In a weird sort of way, Leif found Kara's acceptance and advice becoming kind of helpful instead of troubling. It eased some of the mental pressure over the next few days and let him concentrate more on what he wanted to do and how Celia was feeling than on his fear of the potential consequences. He found he was able to deal with stuff pretty easily that had previously been odd and complicated. Letting things happen with the understanding that they didn't fundamentally change how he and Celia felt about each other made the days go much more smoothly. His new attitude also meant that it didn't bother him at all the next time he entered Celia's room to retrieve their shared laptop and found her sitting entranced by the screen with her hand down the front of her panties. Celia looked up at Leif and pulled out one of the earbuds she was wearing. "Oh, hey, need the computer?" "Kinda, yeah," Leif replied easily. He sat on the bed next to her. "It can wait." Celia was a bit surprised, but smiled at him as he joined her. "Whatever you say." She offered him the earbud she'd removed, and he accepted it. Only after it was in place and he'd settled in next to her did he start paying attention to what manner of porn she'd been watching. "Aw, come on. Two guys?" Celia chuckled. "Well I wasn't expecting company. 'Sides, they're cute together." "Still, though." "Alright, alright. We can change it. Any preferences?" "I dunno. Something with more girls and fewer guys, anyway." "Picky picky." Celia tapped the laptop with her fingertips as she considered, then brightened and began typing for real. "Ooh, I've got an idea." "Yeah? What is it?" "I thought you didn't care." "I don't. I just wanna know, is all." "Well... you know how porn sites are all filled with those incest roleplay things these days..." Leif groaned. "Oh no." "What?" "Isn't that a little too on the nose for us?" "I dunno. We haven't really, like, done anything. You know? We could live vicariously through them." "That's so weird." "Too weird?" "Um... maybe." Leif sighed. "I'm not sure, really. Queue it up. Let's see how it feels." Celia got a video playing, then snuggled back with Leif to watch. "This is a good one. I think you'll like it." "Are you seriously telling me you've already watched this stuff?" "How is that a surprise? I mean, we made out, dude. This is like a step down from that." "Yeah, but-" "And honestly, I had to see how I felt about seeing this kind of thing before I ever really did anything with you." Leif turned toward his sister, but she was still watching the start of the video. He was a bit surprised by her admission, though perhaps he shouldn't have been. It made sense that she'd have insecurities about it just like he did. She must have gotten a head start on dismissing them, was all. That would explain a lot about why it seemed like nothing about it bothered her. "Did you watch a lot of these videos?" Leif asked. Celia smirked. "If you ever checked the browser history-" "I tried not to." "Fair enough. Let's just say yeah, I've seen a few." "It's not gonna be gross, is it?" "Gross how? They're attractive porn actors doing sexy things. They pretend like they're sibbos, is the only difference from other porn." Celia gave Leif a funny look. "Do you think making out with me was gross?" "No. Not at all." "Then this should be fine." Leif remained unconvinced, but he was willing to give it a shot. He tried to focus on the video, and not the subtle motions of Celia's fingers in her underwear. The acting was passable. Better than one could usually expect from a porn video, but not as good as in a real movie. The pretend brother and sister hung out in a bed for a while, just talking a building the scene. Gradually, they started touching a bit, and kissing, then taking clothes off. "They're good together, right?" Celia said. "They're ok," Leif said. "Uh huh. Don't act like you don't like it. I see you getting hard." Leif squirmed. "Well she's got her tits out," he said defensively. "Yeah. And she's got her brother feeling her up and kissing her and shit." "Fake brother." "Still though." Celia was clearly entranced. Leif wasn't sure if she just really liked the actors that much, or if it was something else. Like, perhaps, if she was imagining the two of them doing similar things. Leif finally got over his initial hesitation and joined his sister in masturbating. He had to take his pants off first, which attracted her attention, but after that the two of them had hands busy down their underwear, even as they sat cozily together on her bed. "You can take 'em off if it's more comfortable," Celia said. "No thanks. I'm not ready for that yet." "Didn't think so." Leif and Celia snuck glances at each other while ostensibly masturbating to their porn video. Their eyes met occasionally, and they exchanged shy little smiles. Leif found the video helpful for getting him going, but his sister interested him more on a slightly different level. She was real, for one, not just set in front of him for the purpose of getting him off. Plus there was their whole relationship change of late. The hornier he got, the more he thought about the things they'd done, and what they might still do. "Oh god," Celia whispered. "Look at the way she looks at him." The girl on screen was, indeed, making some very big eyes at her 'brother' while giving him a slow, deliberate blowjob. Leif had to admit that it was pretty hot, even if she was only simulating the emotion behind her smoldering facade. Again, Leif turned to Celia, trying to gauge exactly what was going on in her head. She was focused on the screen, hand moving frantically on her unseen pussy. She bit her lip as she watched, then only belatedly seemed to realize she was being stared at. The turn of Celia's head was what did it. Her eyes were big and full of emotion and lust. It wasn't the same purposeful gaze the girl in the video had used, but it was similar in its effect. Leif was drawn to her by an intangible, but irresistible force. Their lips met softly at first, then with growing insistence. Leif's hand came out of his boxers as he went for his sister instead. She reached for him at almost the same instant, and they fumbled at each other with a passionate lack of coordination. Leif's hand ended up on Celia's breast, with his other trapped awkwardly between them. She went for his hair, pulling his mouth firmly to hers, then down his back to grab his butt. They wrestled around a bit, grabbing and fondling wantonly, lips locked together all the while. Leif groaned into Celia's mouth as his hard cock pressed against her soft, welcoming body. She grinded back against him, encouraging his noises of pent up sexuality. Leif, with the last of his presence of mind, popped out his and Celia's earbuds, kicked the laptop closed, and scooted it to the corner of the bed, out of the way. He rolled on top of her, cock pressed against her pussy, separated only by their underwear. Celia growled eagerly and dragged her fingernails up Leif's back, pulling his shirt up along the way. They had to break long enough for her to remove the article of clothing, and Leif took the opportunity to flip Celia's shirt up over her boobies. She laughed as he dove head-first into her cleavage. "Mmm, yeah. Get right in there," she giggled. Her giggles turned to soft moans as Leif nuzzled and sucked her tits. She tangled her fingers in his hair and caressed his cheek while he orally toyed with her chest. Celia let him play a while, but her impatience to try some things of her own eventually won out. She squirmed around to get some leverage, then rolled him over and got on top instead. She kept her boobs pressed to his face, while gaining more flexibility to grind on him and slide her hands along his half-naked body. The horny siblings writhed around together in a confused tangle of lips and limbs. Their grinding grew more and more insistent as desire triumphed over what dregs of caution remained to hold them back. Celia went for Leif's underwear and had it halfway down his legs before he could muster any kind of response. His instinct was to protest and cover up, or at least it would have been if he hadn't been quite so turned on. As it was, the fiery look in his sister's eyes as his cock sprang into sight made him decide it was probably alright. Celia dove between his legs as soon as his boxers were clear. She made eye contact as she wrapped her fingers around his shaft and gave the tip an experimental lick. Leif had to cover his face with his hands for a moment, overwhelmed by the sensations and what little sense of morality still struggled for life within him. "Oh god." More little licks trailed the underside of his erect shaft, despite his attempt at hiding from reality. Celia's hand slid gently up and down in between swipes of her tongue. "You taste pretty good," she said softly. Leif risked peeking again. Frantic desire was still clearly evident in his sister's face, but her actions were calm and deliberate. She licked, stroked, and kissed his cock in carefully measured motions. "Good to know?" he said. Celia giggled. "I'm not scaring you off, am I?" "I wouldn't say that, no." "Good. Because goddamn, Lee, I want this right now." Leif nodded. "Yeah," he said, his voice cracking slightly. "Me too." Her smiled went wide across her lips. "Good." That was about the end of her restraint. Leif's cock disappeared between her lips as she swallowed it whole. She maintained eye contact most of the way down his shaft until she gagged slightly on the tip. She bobbed her head up and down while running her tongue all over. Leif groaned and arched his back as Celia worked his cock with her soft, wet mouth. It felt absolutely amazing, and he couldn't tell if that was in spite of her being his sister, or partly because of it. Celia sucked Leif off with a manic enthusiasm. She went totally crazy on him, and he couldn't do anything much more than just enjoy the ride. Horny as he'd been right from the start, Leif didn't last long under his sister's dedicated oral attention. He exploded in her mouth, filling it with incestuously obtained cum. For her part, Celia again maintained adoring eye contact as her mouth was coated, and she casually swallowed everything he gave her. "Damn, you were really ready to go off," Celia said. "Yeah. Sorry about that." "No no. That was the point. Had to get the first one out of the way." "What does that mean?" Celia grinned wickedly. "It means I want the next one to take longer." Leif's eyes widened as Celia shimmied out of her panties. She discarded her top as well, leaving her totally naked and endlessly fascinating to his horny little self. Usually cumming once was enough to sate him for a while. His sister's sensual, nude form was cause for exception. Celia slipped in for more kisses, dragging her smooth, naked body along Leif's as she maneuvered into position. Her tongue tasted like him, but not strongly enough to bother him. Not in comparison to everything else she offered. A feral growl emanated from Celia as her thigh rubbed against Leif's returning erection. She shifted just enough to press her pussy against it instead, grinding around a bit while continuing to make out with him all the while. "Are we doing this?" Leif asked breathlessly. "For real?" Celia pulled back enough to look at him with searching eyes and an open, panting smile. "I think so." Leif bit his lip, then nodded. "Ok." He gripped Celia's butt with both hands, squeezing it gently as she rocked back and forth. She was so wet, and her little slit was getting closer and closer to finding the tip of his cock at just the right angle. A particularly determined twitch of Celia's hips lined them up, and Leif gasped as she sank onto him faster than he'd expected, even after all the lead up. She groaned into his mouth, then pulled her head back and stared at nothing, mouth wide open, as she took him deeper. Their connection was made complete in steady increments, and Leif had to remember to draw breath again. He was totally inside his sister. She'd straddled and engulfed him, leaving them joined in a way siblings were never meant to be. Celia grunted and thrust her hips, slowly establishing a rhythm. She braced her hands on Leif's chest, holding him firmly in place while she rode him. "So good," Leif whispered. Celia quirked her lips. "Yeah it is." She sped up that much more, even squeezing her pussy around Leif's cock as a show of just how good it could be. Her eyes rolled back as she gave in fully to her need for loving yet forbidden pleasure. Celia fucked her brother hard while he ran his hands over her warm, naked body. She rode him at an increasingly frantic pace until she managed to push herself over the edge and fall into a well-earned orgasm. Leif let her enjoy herself until she slowed down a little too much for his liking. He was too horny to wait for her to pick up the pace again, so instead he gently rolled over on top of her. Celia stretched out happily beneath him, beaming lazily up at him when they made eye contact. She wrapped her arms around him and pulled him close as he found a rhythm of his own. It was even more insane to Leif when he was in charge. He was actively fucking his big sister. It put an even sharper focus on the emotional impact of their sexual union, and how good it felt to give in and do what made them happy. Celia ruffled Leif's hair and whispered in his ear. "I love you." Leif kissed her softly. "Love you too." With each sibling now having taken the initial edge off, they were free to proceed at a slower, more amorous pace. Their bodies entwined, physically connected in the most delicious way. Leif kept a steady pace in and out of Celia's wet little pussy. He relished the extra control and time to enjoy every sensation there was to discover. Then, too, there was the way Celia looked at him. Her eyes were so deep, so full of emotion. They widened fractionally every time he bottomed out in her. He could see the love she'd verbally expressed to him just by meeting her gaze. "I'm gonna cum," Leif said quietly, not wanting to break the moment just yet. "Ok," Celia said back in the same hushed, reverent tone. "Is it ok if it's, like, on you?" She shook her head. "In me." "Um..." "Please? Just once." Leif wanted to argue. It wasn't a good idea by any means, but he felt a lot of the same desire that Celia did. The animalistic side of him wanted to bury his cock deep inside his sister and fill her up. His rational side screamed at him not to do it. The way she looked at him though... Leif buried his face in Celia's neck as he came inside her, the way she and his sexual self wanted. She cradled him and whispered love and reassurance in his ear. His body tensed a few final times, squeezing out the last of his cum, then relaxed all at once. They lay together, just holding and nuzzling one another in the afterglow. Leif felt like he should move, but absolutely didn't want to. Celia's warm body felt better to him than the softest of beds on the laziest of mornings. "Is that gonna be ok?" he asked. "What?" "What I did. Inside you." Celia nodded. "It'll be fine. I'm still on birth control from... before." She kissed his forehead. "I know it was still kind of a stupid risk, but I really wanted to feel it. Just once. We shouldn't do it again." Leif wrestled with disappointment, unsure if it was warranted. "Any of it, or-" "Just the last part. I mean, technically we shouldn't do any of it again, but..." Leif smiled and closed his eyes. "But how could we not?" he finished for her. **** Sex changed everything. Or, perhaps more accurately, it accelerated the path Leif and Celia had already been on. They'd been spending more time together and developing some very questionable feelings for one another. Now, they were inseparable. Their shared laptop became more of an excuse than ever. It became something of a joke between them to walk in on the other watching porn, and more often than not they'd simply join in. Any and all awkwardness had about it had vanished now that they'd taken things several steps beyond masturbating next to each other. Their parents couldn't help but notice the sibs' newfound closeness. They were spending so much time together that it would have been almost impossible not to. Even though he hoped otherwise, Leif wasn't surprised to get ambushed and Talked To about it. Naturally, his mom picked a time when he didn't have sisterly backup to subtly bring the conversation up. Even worse, it was first thing in the morning, before he was really awake yet. "There you are," Cindy said casually as he stumbled into the kitchen, "how you feeling this morning?" Leif shrugged. "Not sure yet." "Is you sister up?" Stan, his father, asked from the other side. Leif shrugged again, not yet aware enough to be worried about the flank attack. "Dunno." "You do seem to be spending a lot of time together lately, though," Cindy suggested lightly. "A lot," Stan agreed. Dawning realization crept through Leif's body. "Yeah? So?" "Just... we're concerned," Cindy said. "About what? Cel's been through some rough stuff lately. But it's getting better. Nothing more to it." "Rough stuff?" Stan asked. "He means the breakup," Cindy supplied helpfully. "And you're right, Leif, she does seem to be doing better." "Good. Then what's the issue?" "Well... she's latched onto you pretty hard," Cindy said. "It might not be the best thing for her right now," Stan said. Leif rolled his eyes. "Ok, I'm going back to bed. It's too early for this." "You'll be late for school," Cindy argued. She gently took Leif's arm. "Come sit, I'll get you some breakfast." "No more interrogation?" Leif asked. "So dramatic," Stan said. "This isn't an interrogation." "Coulda fooled me." "All we're saying is maybe it would be better if Celia spent more time with her other friends. Or some other boys," Cindy said patiently. "First of all, why not tell her that?" Leif grumbled. "Secondly, like, what, you want her to get stuck in an unhealthy rebound?" "Not at all," Cindy said. "But maybe... maybe it's not so healthy her spending all this time with you either." Leif tensed, but tried not to show it. "How so?" "Well... she wasn't in her room one evening when I went to check on her," Cindy said. "She was with you," Stan added. "In bed." "It was very cute," Cindy said. "You two all cuddled up together, sleeping so peacefully. I just don't know if I like that happening regularly. Not at your ages." Such a mix of emotions and sensations surged through Leif. He couldn't imagine when he and Celia had been caught, but it wasn't like he could deny it. How the hell they'd managed to come off as it being a purely innocent thing, he had no idea. In all likelihood, they'd been naked under the covers at the time. "She was having trouble sleeping," he muttered. "Yes, we're concerned about her too," Cindy said. "But she'd been doing much better lately, and it might be better if you two had some space, is all." Leif sighed and rubbed his forehead. If only his mom and dad had any concept of exactly why Celia was doing better. That she had, in fact, turned to him for more than either parent could imagine. "What exactly do you think's gonna happen?" he asked. That, as he'd hoped, quieted the deluge for a moment. "Um..." said Cindy. Stand coughed. "Well..." Leif shook his head slowly, partly for effect, and partly to help hide his expression. "You'd think you'd be happy your kids were so close. That we actually care about each other. But no. You gotta make it weird." "I wouldn't say that, exactly," Stan mumbled. "No, I know. You'll just hint and vaguely threaten some kind of disaster." Leif shook his head again. "It's too early for this. I'm gonna go get ready. I'll have to grab breakfast on the way." "No, no. I'll make something," Cindy said. "You get dressed. It'll be here when you get back." Leif shrugged. "Yeah, alright." He held his face in check until he was out of the room, then breathed a huge sigh of relief. Somehow, he was pretty sure he'd gotten away with it. Still, suspicion was mounting. That wasn't good. Celia was still dozing as Leif crept into her room. He laid a soft kiss on her lips, then pulled back in time to watch her eyelids flutter open. Her lips twitched into a lopsided smile. "Hey, you," she said as she stretched out lazily. Her bare tits popped out from under her blanket, and she made no move to cover up again. "Hey yourself," Leif said. "So, listen, Mom and Dad kinda just ganged up on me in the kitchen." Celia's smiled turned to a confused frown. "What?" "You know. About how close we've been lately." "How is that any of their business? Why would they even care?" Leif shrugged. "I mean, to be fair, we have kinda been doing all sorts of sexy stuff. Which is what I think they're worried about, even if they wouldn't come right out and say it." "Ugh. Of course they are. They couldn't just let a good thing be, could they?" "They might not see it as a good thing at all." "Yeah, well... yeah. Goddammit." Celia pouted. "It was so nice waking up like that. Why'd you have to bring reality into it?" "Sorry. Had to give you fair warning, since I really need to get going." "I guess." Celia tilted her head up. "One more kiss?" Leif nodded and bent toward her again. This kiss lasted significantly longer than the quick wake-up one. It was tempting just to fall into bed with her, but that would be asking for way more trouble than he was prepared to deal with. "I'll see ya later, ok?" Celia nodded. "Sure. Guess we'll have to be sneakier for a while though, huh?" "Yeah. We sure will." **** Apparently, part of Celia's plan to be sneakier involved picking Leif up from school later on. He hadn't been expecting something like that at all, but he also didn't question it too hard. It was nice to spend some time with her away from the suddenly prying eyes of their parents. "What's the occasion?" Leif asked as he settled into the passenger seat. "I don't remember you ever picking me up before, unless one of the 'rents made you. And somehow I can't see that happening today." Celia quirked a smile as she pulled away from the curb. "We're being sneaky, remember? We might have to not fuck around at home for at least a few days." Leif felt a burst of disappointment, even though he'd basically been thinking the same thing. It was worse to hear it out loud, somehow. "So... what, then?" "Well, we could grab some food. Hang out somewhere else for a while. Officially, I'm hanging with Kara this afternoon. You know, to avoid suspicion." "Right. Sure. And what am I doing? 'Officially?'" Celia shrugged. "I dunno. Make something up and call home though, would you?" "Right. Of course." Leif made up a story about working on a school project for the afternoon, rolling his eyes at Celia's attempts to distract him while he was on the phone. Despite her sudden and childish kidnapping, he was actually pretty happy to have some time with her away from prying eyes. The thought was nice, even if the execution left something to be desired thus far. The restaurant they arrived at wasn't terribly busy, being the middle of the afternoon and all. That was fine by Leif, who was just a little anxious about being on a pseudo-date with his sister. It wasn't like anyone would know that's what it was, and it wouldn't really be any different from them just grabbing a bite any other time, but that didn't stop his mind from conjuring a vague sense of unease. Celia helped defuse his tension by seeming totally unconcerned and acting like everything was normal. Which it was, more or less. "Don't look so nervous," she said. "It's just us." "Yeah, I know," Leif said. "But, like, it's different, too." "Well... kinda. Maybe." Celia shrugged. "I like it though. Kinda neat that nobody knows." "Sure. But super-worrisome that someone might know." She giggled. "You're overthinking it." Leif conceded that he probably was. No one paid them any special attention at all, even when Celia started playing footsie with him under the table, just to tease him. He picked at his food once it arrived. It was early for supper, and he'd already had lunch, so he wasn't overly hungry. Celia toyed with her meal as well, though somewhat more artfully. "Is this a date?" Leif asked. Celia considered the question. "Not sure. Kinda, I guess." "'Cause I don't know what else to call it." "I mean, it could be. We're not doing amazingly so far if it is, though." "We're not, are we." Celia chewed on her lip for a moment. "No," she decided eventually. "It's not a date." "Just like that?" "Well, this way we can just be a brother and sister eating out a bit awkwardly. That's better, right? Better than an awkward and confused date?" Leif shrugged. "I guess." Celia threw her hands up. "Bleh, whatever. I don't know. This all made more sense in my head." "Yeah, no, it was a good thought. Just... I feel like there's too much pressure here to, like, do something. Or not do something. I'm not even sure which." "You might be right." Celia stabbed another forkful of food. "Wanna finish up and get out of here? I had another idea that's probably better." "Oh yeah? Like what?" She grinned mischievously. "You'll see." **** About half an hour later, Leif did, in fact, see. "Kara's house?" he asked, somewhat baffled at the choice of venue. "Yep." "But... why? How is that possibly any better?" "Because no one's home." Celia walked brazenly through the yard, headed around the house. "Come on." Leif, left with no other good choices, followed. "I don't know about this." "It'll be fine. Trust me. No parents, ours or Kara's, and no Kara either. No one watching. Just us." Leif liked the sound of being totally on their own. However, any comfort derived from their solitude was offset by being in fairly unfamiliar territory. Celia was far more at ease. She'd been to Kara's house enough times over the years that it may as well have been a second home for her. She led her reluctant brother around to the backyard without any sign of hesitation or tension. Clearly she had complete confidence in her plan for alone time. "What happens if someone sees us?" Leif asked. "So what? How would anyone know you're my brother?" "I mean, like, Kara or her parents? They'd know." Celia shrugged. "Kara promised it'd be all clear for a while. We'll be fine." "But-" "Come on, Lee. Please just give it a chance?" Celia turned and met his gaze with pleading eyes. "I'm so tired of having to hide all the time. I mean, it's fun, but it's exhausting too, you know?" "I do, actually, yes." Celia stepped toward Leif and slipped her arms around him. She gave him a soft, lingering kiss. "It'll be good. You'll see." Kara's backyard featured a pool, which Leif had been invited to use a few times over the years, which was the main reason he had any familiarity at all with the property or Kara's family. Celia made a beeline for the water once she felt she'd sufficiently convinced him to give their trespassing a shot. "Now what?" Leif asked as Celia started shedding clothes. "Swimming, duh," she said as though it was obvious. "I thought you wanted to, like, hang out." "We can do both." Leif rolled his eyes. "I didn't bring a suit." "Neither did I. Did you already forget that we're all alone?" Celia finished with a lascivious wink as she pulled down her panties without any consideration at all for being in someone else's yard in the middle of the day. Her shameless stripping worked quite well, however, as her naked form was enticing enough for Leif's mind to shift gears. He stepped closer, but she giggled and dove into the water before he could reach her. He had a decision to make at that point, and all of a sudden it seemed much simpler than it had a moment ago. Naked sister trumped possible embarrassment and scandal. Not even a fair fight. Celia watched from the side of the pool as Leif stripped out of his clothing in turn. He wasn't quite as sure or graceful about it, but he quite liked the glint of lust in her eyes as he revealed himself. Leif dove in after Celia, surfacing somewhere in the middle of the pool. He wiped water from his eyes just in time to see her swimming for him and latching on. Her naked breasts pressed to his equally nude chest as she wrapped him up in a delightfully slippery kiss. He grabbed her butt while simultaneously trying not to lose his balance and go under. Thankfully, Celia only held him for a short time before pushing away and flashing like a mermaid as she swam the other way. Unlike such a mythical creature, she made quite a teasing and erotic sight from behind as her legs kicked and alternated showing and hiding what lay between. Leif was fully hard already and grateful for the slightly obscuring effect of the water. He still hadn't quite adjusted to the idea that no one else was going to sneak up and catch him totally perving on his sister while she did likewise to him. He belatedly swam after Celia by the time she was almost to the far edge already. She waited for him to catch up, and they shared another slippery, naked embrace before she again darted away. Leif grinned, beginning to get into the game. She wasn't making it hard for him to get some action, but the extra playful element added some sensual fun that they'd never really had a chance to explore previously. Celia's escapes grew shorter and shorter between getting caught again. Her false resistance crumbled until she was doing little more than wiggling around in Leif's grasp, rubbing her slick naughty bits all over him and causing his hands to roam even more wildly. She was finally trapped in the corner of the pool. She had nowhere to run, not that she had any interest in doing so. Leif pressed in on her, rubbing against her and grinding his hard cock on whatever soft part of her it could find. She kissed and groped him hungrily while rocking her hips right back. They were so close to fucking, right there in someone else's backyard pool. If Celia hadn't been so slippery and hard to find purchase against, Leif was sure he would have taken her right there, previous fears be damned. A low growl formed in his throat, vocalizing his need for his sister. He had an image of picking her up and throwing her onto dry land, then rolling around together in the grass, joined together in blissful sibling sex. Instead, his heart skipped as he caught sight of a form in his peripheral vision. He whirled his head and found Kara sitting calmly at the pool's edge, watching the two of them with an amused smirk on her face. "What the fuck!" Leif tore away from Celia, moving to cover himself, then changing his mind and looking toward his clothes, then finally settling for looking desperately at his big sis for help. Celia rolled her eyes in total disgust. "Seriously, Kara, you told me we could have this place to ourselves for a bit." "Yeah, sorry 'bout that," Kara said, not sounding the least bit apologetic. "I couldn't help myself. I had to see." "You most certainly did not." "Easy for you to say." "Yes, it is easy for me to say. You don't just interrupt like that because you're curious." Celia splashed Kara, who in turn ducked away, but didn't otherwise move. "Goddammit. It was going so well, too." "I could see that," Kara agreed. Celia splashed her again, then climbed out of the pool. Leif forgot some of his indignation and embarrassment at the sight of his sister's lovely, dripping wet body catching the late afternoon sun. Celia smoothed back her hair and shook off some of the water droplets clinging to her. She gave her butt an unconscious little wiggle in the process, further luring Leif in to stare at her. "Come on, Lee," she said. He glanced up at her face. "What?" She gestured out of the pool. "Come on." "Where are we going?" "We're gonna go mess around on Kara's bed." "We are?" Leif asked. "You are?" Kara likewise demanded at almost the same instant. "Yes," Celia said. "We are. Since apparently leaving us be for an hour was too much to ask." She shrugged. "That or your parents' room, I guess. Good luck explaining the mess we make in there." Kara rolled her eyes. "Ugh. I just wanted to know for sure. You don't have to be mean about it." "I do, actually." While the girls squabbled, Leif climbed out of the pool. He was rather self-conscious about his erection sticking out so plainly without even the distortion of the water to protect him, even more so when Kara's eyes drifted over to it momentarily. Celia took Leif's hand and led him away. He looked over his shoulder, verifying that Kara was still watching him as they walked away. "At least dry off first," Kara called after them a little sulkily. The last Leif saw before he entered the house, Kara was stripping down for a swim of her own. "We're not actually doing this, are we?" he asked. "I mean, this is really getting weird now." Celia looked defiant. "I'm not letting anyone ruin this. We were having fun, weren't we?" "Well, yeah, obviously." "And you wanna fuck around, don't you?" Leif couldn't very well deny that he did, not with his prominent hardon that had shortly before been grinding around Celia's pussy. "Yeah. But maybe we could just go home?" Celia shook her head. "Parents," she said simply. "Maybe they won't be there?" "Not likely." They stopped at the bathroom to dry off properly, after trailing a small shower of drips through the house to that point. Leif occupied himself with toweling off, and was caught halfway by surprise when Celia slipped in and gave him a fierce kiss while her arms encircled him. She was so warm and soft, and he was way too horny to resist any further. She was right, too, that the risk of being caught here probably was less than at home, even if it felt like the reverse to him, simply due to unfamiliarity. "Which way is Kara's room?" he asked. Celia beamed. "Thought so." She led the way, ass swaying in full seduction mode. Leif followed like a puppy and fell into bed with her as soon as they arrived at their destination. They picked up right where they'd left off at the pool with lots of making out, grinding, and groping. They rolled around, kicking the covers out of the way, and growling and moaning as the need arose. It was so liberating not to have to worry about being quiet and stealthy. Kara already knew what was going on, and presumably she was going to leave them be. Even if she didn't, Leif recognized that she wasn't likely to be any more a pain in the ass than she already had been. Inevitably, Leif's cock found its mark. Celia gasped loudly and arched her back as she was just barely penetrated. She bucked slightly under him, urging him on. He thrust deeper into her, then deeper again. He groaned happily at the feeling of burying himself fully inside his sister's tight pussy. "Go for it," Celia whispered. "Don't worry about holding back this time. I want everything." Leif kissed her firmly, then adjusted his position and gave her what they both wanted: free, unrestrained, untamed fucking. The bed creaked in protest as Leif hammered his sister's little cunt. She moaned and growled, and her pussy squelched with every hard thrust. Their mixed sounds of sex and pleasure echoed out of the room and down the hall, and neither of them particularly cared. It was all about them, their pleasure, and there was no one around to have to hide from. Leif fucked Celia as hard and long as he could before pulling out and spraying his cum all over her tummy. She smiled and watched the totality of his orgasm before running a finger through the mess he'd made. "Nice not having to be quiet, isn't it?" she said. He nodded with a lopsided grin. "It really is." They cuddled together a while, still in no hurry, or with any desire to get dressed or cover up. Celia toyed with her cummy tummy some more, while Leif nuzzled up to her boobs and rested his head. "Thank you for coming with me this afternoon," she said. "I needed this." "Mmm, yeah, I hear ya." Leif palmed one of her breasts just to feel its comfortingly soft weight. "You know, I assumed this thing between us wasn't going to last, that it was a phase for both of us maybe. But, like, are we ever stopping?" Celia was silent for a long moment. He let her be, certain that she was giving his question due consideration. "I could fall in love with you," she admitted. "I mean, I already love you and all, but getting closer lately... it's been kind of amazing. Way more than what I thought I was getting into. In a good way, I think." "That makes sense." "Yeah?" "Yeah. Kinda." Leif played with Celia's nipple. "I dunno. I like it too, and I definitely feel... something. It's a weird feeling, but not a bad one." "Mmhm. That'd be the one." They lay together a while longer. Celia eventually rolled over top of Leif in a smooth, easy motion. She straddled him, pressing her pussy to his restiffening cock. She rocked back and forth until he was hard enough, then slipped right onto his shaft. Her movements were steady and gentle. She rode him slowly, pouring emotion rather than energy into their second round of sex. Leif lay back and admired his sister's grace and beauty as she undulated atop him. There were things about her he'd never noticed that were now all too clear after she'd been stripped both physically, and emotionally. There was nothing separating them anymore, either literally or figuratively. Celia wiggled around on her brother's cock, eyes half-closed, but still looking down at him with a special half-smile. She dipped down and brushed his lips with hers. He held her in place when she tried to straighten up and kissed her back more firmly. Their lips and tongues said what their voices couldn't yet, what their bodies knew but their minds yet pondered. A faint shuffling sound caused both siblings to turn their heads at the same time; not in a quick, alarmed way, but rather a slow, disbelieving sort of way. "The hell, Kara?" Celia asked. "Not perving, I swear," Kara said as she dug through her dresser right next to them. "Carry on. Don't mind me." "I mean, for real though," Celia said. "You're being a shit friend today." "You're fucking your brother in my bed," Kara countered. "I'd say we're even." "She has a point," Leif said quietly. Celia fought to keep a straight face, then lost it. She snorted and shook her head. "Please just go," she said. "Give us another ten minutes at least." "Or twenty," Leif suggested. "Yeah right. Like you're gonna last that long," Kara said. She turned away, some clothes bundled in her arms. "I brought your guys's stuff in, just in case you decide to stop being naked at some point. I'ma go have a long, hot shower. If you're still here after that, I won't feel the least bit bad about interrupting again." "Off to play with the shower head, I bet," Celia whispered a little too loudly to Leif. "You know it," Kara said just before leaving the room. "And yet I'm not even the most wanton of the two of us right now. Go figure." Celia and Leif were left alone again. They'd been fully, unquestionably caught fucking each other, and yet nothing bad had really come of it. Then again, Kara was probably not the best benchmark for the reception they'd be likely to get from other people. After a long, quiet moment, Celia resumed rocking on top of her brother. Leif hadn't gone soft in her despite the interruption. Her pussy just simply hadn't allowed that possibility. "This is so messed up," Leif said. "What, screwing your sister?" "No. Well, yes, but I didn't mean that. More like I don't even care enough about Kara seeing us to want to stop. I'm getting used to being with you. It's getting normalized in my head." Celia tilted her head with a faint smirk. "Can't get enough of me, huh?" "That too." Leif slid his hands up her body, briefly fondling her breasts, then pulled her down toward him. Their kisses were long and soft, loving and revealing. They caressed, fondled, and enjoyed each other in the aftermath of their interruption. Consideration for anyone else faded once more as they lost themselves in their incestuous lust. Celia rode Leif until she came, savouring every last bit of the exquisite pleasure, then finished him off as well. The sated siblings snuggled together afterward, secure in each other's embrace, until Kara returned. She seemed a bit annoyed that they were still naked in her bed, and even moreso that they barely registered her attempts to kick them out. Eventually Leif gave in asked Kara for his clothes. She even turned around while he dressed, though it was a bit late for that to do any good. Celia followed suit, leaving all three of them more or less properly attired. They hung out together for a bit. It wasn't nearly as awkward as Leif expected, though Kara remained a bit perturbed since he and Celia mostly spent their time making eyes at each other in spite of Kara's best efforts to focus some attention on herself. Some last little bit of their former semi-normal life had snapped, and it probably wasn't going back together easily. **** It was just getting dark when Leif and Celia returned home that evening. They were still smiley and giggly on their approach, and had to calm down and put on straight faces before entering. Unfortunately, they forgot all about their cover stories, and how they'd claimed to be doing different things all afternoon. Their parents' faces upon walking in reminded them pretty quickly. "Well," said Cindy, barely contained tension all over her voice, "what have you two been up to?" Leif shrugged and did his best attempt to play it cool. "Oh, you know, just doing some stuff. Cel came and picked me up after-" "Oh I am so not in the mood for this shit right now," Celia said. Leif turned to her in pure shock. He'd been expecting a line like that from anyone except her. "Um... wha-" "I had a lovely afternoon. I don't need a fight to ruin it for me now." Celia pulled Leif in and kissed him in a definite, territory-claiming kind of way. "I need a shower," she declared as though she hadn't just started world war three, home edition. No one else made a peep as she strode past Cindy and Stan. Leif was left just as stunned as their parents, but also very outnumbered. "Yeah, so, uh..." Leif cleared his throat. "Like, you know..." "What the hell was that?" Stan demanded. "It was probably nothing," Cindy said desperately. "Maybe she just... maybe..." Leif experienced a moment of clarity as he watched his mom and dad try to resolve a passionate kiss between their children. He'd been afraid of the consequences of them finding out, but all along he and Celia had been more in control than anyone else ever could be. It was their life, their choices, their chance to set the story the way they wanted. Honestly, what was he afraid of? "So me and Cel have been, uh, messing around," Leif said, his voice sounding foreign to his own ears in the deathly quiet room. "Nothing to worry about. We've got it all under control." "What does that mean?" "What are you saying?" "How could this happen?" "Are you both crazy?" Leif smiled, shook his head, and walked right past the barrage of follow up questions. He didn't need to answer them. He'd wait for Celia. They could answer together, if at all. The shower was already running when Leif reached the bathroom. He didn't even hesitate at the closed door, and just walked right in. Celia poked her head out at the intrusion, but nodded when she saw who it was as though she'd been expecting him. "Sorry about leaving you out there like that." "Yeah, that was kinda awkward. You coulda stuck around for a minute." "I know. I just couldn't, is all. Like, the whole bullshit explanation, or the aftermath of the truth, I couldn't do that. Not yet." "Well it went better than expected, I think. Not good by any means, but better than it could have." "Good." Celia disappeared back behind the shower curtain. "Guess I owe you now, huh?" Leif let a slow smile creep over his lips. He started pulling off his clothes. "Yeah. I think maybe you do." There wasn't even a question of Leif joining Celia in the shower. It was happening, that was all. She made room for him and let him rinse off before getting all close and gropey. By mutual, unspoken agreement, they let the subject of their parents drop entirely. It was far more fun to mess around while cleaning up from their earlier sexy times than to worry about further repercussions. Slippery fondling and makeouts transitioned smoothly to snuggling in bed afterward. It had been quite a day, and neither sibling wanted to be without the other. Not only was there a security and comfort to sharing body heat and physical reassurance, but there was no chance of one of them getting ambushed alone by some desperate ploy from their parents. "This is really happening, huh?" Leif whispered. "Like, we're officially doing this now." "I think so, yeah," Celia whispered back with a shy smile. "I mean, Kara knows. Mom and Dad know. It's not really a secret anymore." "Not really, no." She bit her lip. "Is that ok? We never really talked about where this was going. Not in any kind of long term sort of way." "More than ok," Leif assured her. He kissed her softly. "It's so good." "Yeah?" "Yeah." Celia nodded and got even more firmly embedded against him for nakey snuggle times. "Good." **** Leif assumed the subject of he and Celia would be coming up again at some point. He hoped that it could be a calm, semi-rational discussion since the initial blowup seemed to have been averted. As it turned out, there was no followup at all coming. Cindy and Stan studiously avoided making any mention of what their children were up to. At first that was worse than shouting, because Leif had absolutely no idea what they were waiting for, and the uncertainty was killing him. Eventually the fear faded, and he realized they just really, really didn't want to talk about it. He could accept that, and it might honestly have been the best solution. It wasn't like anyone would have come away happy from the argument. Leif and Celia, in turn, remained as discreet with their fun times as possible. It got easier for them, since their parents were extra careful about leaving them their privacy, but they still needed to get out of the house together a few times a week just to feel like they had space to be themselves. Despite her complaints and mischief making, Kara was fairly helpful in keeping Leif and Celia sane. Her house provided a much-needed sanctuary at times, and the simple fact of someone else knowing and generally accepting what the sibbos were doing was quite a relief. There was a lot of time just spent hanging out in their rooms too. Not even doing inappropriate activities necessarily, although there were plenty of those too. Just being together, watching movies, lounging around, whatever. And if one caught the other in a state of undress or playing with themselves, that had become entirely a non-issue. "You know what's funny?" Leif said one evening while lying with his head in Celia's lap. She shook her head, eyes remaining glued to the laptop in front of them. She had a fake-incest porn video playing even though they'd just finished messing around. "What's that?" "How annoyed I used to get when you'd use the computer to watch porn all the time." Celia snorted. "Yeah, you really got irked by it sometimes, didn't you?" "And now here I am watching with you like it's the most normal thing." "Well it never had to be as weird as you made it out to be." "So you've claimed." Leif nuzzled into a slightly more comfortable position on her thigh. "You might have had a point though." Celia smiled and ruffled his hair. "Maybe I did," she said softly. She closed the laptop and scooted it aside. Leif protested when she slid out from under him, but she ignored him and climbed across his lap anyway. He stopped complaining when she started grinding on him. "Again?" he asked. "I got worked up watching that vid. It was a good one." "It was alright. Their acting wasn't great." "It rarely is. That's not the point." Celia braced her hands on Leif's shoulders and rocked harder back and forth. His cock stiffened quickly as her slick pussy slid all over it. "Don't tell me you're not interested." Leif smirked crookedly. "No, I definitely wouldn't say that." Celia smiled back and leaned down to kiss him. Her hair fell across his face, and her breasts teased his chest. He pulled her tighter to him, savouring the feel of her body on his. "Definitely interested," he murmured. "Thought you might be." They kissed again, long and lingering. "Love you," Leif whispered. "Mmm. Love you too." Celia took his cock inside her, then rode him gently and unhurried. They'd already burned off their excess lust, so they were under no pressure this time around. They had the privacy of semi-understanding parents, their mutual love, and the rest of the evening to kill. Somehow, things had worked out just fine. **** Bonus Scene **** Kara perked up when she saw Reeve's car in the driveway. All this Leif and Celia nonsense lately had been leaving her with some mixed emotions, and some brotherly company would help her out with that. Their mom and dad were home too, but that didn't put too much of a damper on her enthusiasm. She wasn't looking for sexy times. Not yet, anyway. Reeve was in his room. He was lying on his bed, intently texting on his phone. He didn't bat an eye as Kara shut the door, padded over, and slipped onto the mattress beside him. "What up?" he asked. "Got something interesting, actually," Kara said coyly. She waited until Reeve put his phone aside and looked at her. "Like what?" he asked. Kara grinned. "Wellll..." "Don't do that. You wanna tell me, so tell me." She coiled some of her hair around her finger. "You know Cel?" "Of course." "And you know Lee?" Reeve frowned for a second. "Her brother?" "That's the one." "What about them?" Kara grinned wider and flicked her gaze toward the door to reassure herself that they had privacy. "They're totally banging," she said in a loud hush. Reeve's eyebrows shot up. "They are?" "Yep." "You're sure?" "Dude, I caught them almost going at it in the pool. Then they actually did it in my bed." "Your bed?" "Yeah, kinda annoying actually." Kara shrugged. "Young love, what ya gonna do?" Reeve snorted. "Yeah, 'cause you're so worldly." "Well... I'm not as anxious and excitable as they are." Kara thrust her chin out defiantly. "I wouldn't go around screwing on other people's beds." "Only 'cause you never had the chance." Kara punched Reeve's shoulder lightly. "S'got nothing to do with it." "If you say so." She grumbled and folded her arms. He remained calm and relaxed, stretched out in his reclined position. A moment of silence passed. "So I guess we're not the only ones now, huh?" Reeve said. "Not special anymore." Kara gave him a look. "Not special anymore?" "You know. Unique." "Pff, whatever. Our thing's still better." "Is it? On what criteria?" "You tryin' to be an ass?" "No. Just asking. Wondering if you're jealous." "As if." Kara turned her head away, arms still folded over her chest. Reeve sat up. He reached over to her chin and applied gentle pressure until she turned back to look at him. He kissed her softly. "You're right," he said easily. "They got nothing on us." "S'what I'm sayin'. They're just puppies, really. All eager and excited." "Puppies," he agreed. He kissed her again. Kara unfolded from herself as her brother's embrace worked on her. His lips caused such wonderful, tingly feelings. It wasn't like she needed those feelings. They weren't what she'd come here for. But once they started... She pressed against him, pushing him onto his back, then following him down. He felt so good, so comforting in the wake of her friend's new relationship. Reeve was always there when she needed him. "Did you tell Cel about us?" he asked. Kara shook her head. "Not all of it. She's always known some. May have guessed the rest." "Do you think you will? Now that she's all brother-happy and shit?" "I dunno. Maybe. If it comes up. Still not anyone's business." "No. It isn't. But it's nice not to be alone with things sometimes." "True." Kara shrugged. "We'll see." She kissed Reeve some more, making out with him in his bed in the easy, familiar way they had together. His hands slipped under her shirt, warming her skin where he caressed her. She luxuriated in his touch, in all the feelings it evoked within her. Clothes started coming off. Kara hadn't really been sure that it was that kind of make out session, but these things tended to work themselves out. She and Reeve had more than enough experience with one another to let their bodies basically decide for them. Doing what felt right was all it took. Kara became increasingly horny and excited as she got her brother naked, and he did the same to her. The crazy, early days of their relationship were long past, but she still reacted with much of the same fire when they were together like this. He still did things to her that she couldn't fully comprehend, but absolutely adored. Still, there was nothing desperate or rushed about their movements. They knew what was coming, that it took time to get there, just as it always did. Kara kissed Reeve, then down his neck to his chest. She nuzzled his shoulder as she felt his fingers tangle in her hair. She growled low in her throat as Reeve rolled her over. She accepted his kisses, then bit her lip as he dipped lower and sucked on her breasts. His tongue flicked over her nipples just the way she liked, the way that always got her anticipating more. He meandered lower and lower, arriving at her waiting pussy. His licks and kisses became all the more meaningful as he lapped at her wet slit and teased her little clit. Kara moaned and squirmed as her brother ate her out in his experienced and practiced way. He knew what she liked, what built her up, what got her off. His tongue was a sweet instrument of illicit pleasure in their incestuous play time. "Mmm, yeah," she breathed. She grabbed a loose handful of his hair in her fingers for some feeling of control, even though she didn't intend to guide him at all. He knew what she liked even better than she did. Reeve's licks focused more and more on her clit as she got closer. She whined and panted and pawed at his hair, then clapped a hand over her mouth as she came all over his skillful tongue. He gave her a few more long, gentle swipes to bring her down. The flat of his tongue trailed all the way up her pussy with only the barest caress of her sensitive clit, then dodging it altogether as she relaxed. A final kiss of her happy little pussy, then he crawled back up to her. Kara smiled lazily and pulled him in for a kiss, licking tastes of herself off his lips. They made out again for a bit before she rolled him over and took her turn on top. She sat up almost straight, hands braced on his chest, pussy pressed to his cock. He was deliciously hard against her. There'd been no doubt he wanted her, but his physical arousal was such a visceral reminder. She loved feeling her brother like that, and not just because of how horny it made her. Reeve grabbed her hips, urging her closer still. She grinned and rocked back and forth, spreading her wetness along his shaft. Teasing him like that was a fun was to get them both ready for penetration, plus he made such a cute face every time she almost took him, then slid back instead. Kara finally twitched her hips just that little bit extra and caught her brother's cock at the right angle. She sighed happily as she sank onto him, bouncing slightly to work herself all the way down. The moment when he was fully inside her was one of her favourites, and she paused briefly to savour it. Reeve seemed just as happy about being inside her. He smiled broadly and ran his hands up her tummy, over her boobs, then back down again. "Damn that's nice," he whispered. Kara nodded with a matching grin. "Always is." She rolled her lower body in slow, steady arcs, grinding on Reeve's cock in small but sensuous movements. She very gradually increased her speed and range of motion until she was sliding up and down and putting a bit of bounce into fucking him. She rode him good without undo rushing, letting a sheen of sweat develop over the course of her sexy workout. Eventually, when the time was right, she let him flip them over and get back on top. Reeve was all worked up now. Her teasing and slow fucking had him looking for more, just the way she knew they would. It was a predictable dance, but one that grew all the more intricate and subtle with every revision. He fucked her harder, spreading her legs wide in his quest for satisfaction. She moaned and held him, digging soft fingers into his back, sparing him her nails since they left marks that sometimes brought awkward questions. Kara came for a second time while Reeve grunted and pounded her little pussy. He was getting so close. She whispered affections in his ear and nuzzled his cheek, urging him to completion. She sighed in satisfaction and wrapped her legs around his waist, holding him in place as she felt hot brother-cum exploding within her. She loved it filling her all up like that. Such a tangible punctuation to an already amazing expression of their sibling love. They stayed tightly cuddled together afterward. Kara wouldn't let Reeve go until he'd softened nearly completely, and even after that she brought his hand down and made him cup her cummy pussy in a soft and comforting way. "I bet Cel and Lee aren't nearly so good together," Kara mumbled cozily. "No, I'm sure they aren't," Reeve said. "Are you patronizing me?" "A little, yeah." Kara snorted and snuggled tighter to his chest. "Why do I put up with you?" "Because you love me, and you love fucking me, and also you have no choice because we live together, and I know all your secrets already, and-" Kara shut him up with a long, deep kiss. "Hush. That wasn't a serious question." "I know." They lay together a while longer, until they heard a call from further in the house. Reeve groaned and rolled out of Kara's arms. "Well shit. Guess that's me," he said. "I didn't hear anything," Kara said, reaching for him. "Yes you did. Mom called me, and you know damn well we don't want her to come looking." "Ugh. Fiiine." At least she got to watch him dress, which was somehow almost as fascinating as watching him undress. Almost. Reeve blew Kara a kiss before slipping out the door, then she was left alone. She curled up by herself in her brother's bed, only his scent remaining to keep her company. She lay like that a while, hoping he'd be back, but knowing he probably wouldn't be. Not for a while. Besides, she'd gotten what she wanted already, even if some more cuddle time would have been nice. She reached down between her legs, slowly tracing a finger along her pussy and catching some of his cum. She brought it to her mouth and sucked her finger clean, smiling as the sexy taste hit her tongue. Kara stretched nude and catlike along the length of Reeve's bed, then rolled to her feet and scrounged up her clothes. She got dressed, smoothed out her hair so it looked more casually ruffled than sexually mussed, then padded out of the room. There'd be other chances, but for now it was back to pretending like she didn't fuck her brother on a semi-regular basis. It had worked for them so far. It might be time to really have a talk with Celia about all this family sex stuff going on. Let her in on everything. It wasn't like she'd be judgey about it. But then again, Kara really liked having her and Reeve's true relationship just between them. A perfect little secret, other than the hints Celia and Lee had about it. She shrugged and kept going. It might be one of those things that just naturally came up at some point. Or maybe it would never feel right. Either way was fine. She'd figure it out. For Pics visit:---->>> https://bit.ly/2ReHUJI
