Just one Kiss

Ryu found that stroking himself was simultaneously the most embarrassing and most intense masturbation he could ever remember. He didn’t need to be embarrassed about it, Luna was rubbing her pussy in her own bed too. But he hadn’t done anything quite like this before. Not with nearly the same emotional mix.

They didn’t know it at first, but they each helped the other to an insane orgasm. Both making big messes, and leaving themselves weak and panting afterward, still just thinking about each other.

****

Luna actually found herself humming cheerfully the next morning when she got up, and even sang to herself in the shower. She only thought about Terrence when she realized that she didn’t want to dwell on her breakup. Didn’t have that destructive urge to pick it all apart in retrospect.

Just Ryu. That’s all she wanted to think about. Ryu and… and that kiss. And what led up to it, of course.

She’d been so horny after. Rubbing herself in bed, thinking about her brother. Thinking about him stroking himself while thinking about her. It was a deliciously vicious cycle.

Even now, standing under the decadent warm shower spray, Luna had the urge to play with herself, or bring down the shower head and turn it on her pussy. Or something. She’d had a really good cum last night. She shouldn’t be worked up again already, even just at a low level.

But Ryu though….

What she’d give to have him in the shower with her right now. Not that they could do that. Obviously. But she could think about it. Thinking was fine. Sort of.

His hands on her, his eyes on her, his… other things on her….

Luna flushed just at her own imagination. Going too far with it. Like… sex was out. She could picture it in her mind so very easily. All kissing and rubbing up on one another, all slippery and horny. And… and maybe Ryu would slip somewhere he shouldn’t. Maybe right inside her. Luna didn’t think she’d stop him if he did. That was a scary thought.

She gave in and grabbed the shower head. She leaned back against the wall and pressed the spray to her pussy, finding her clit and biting her lip as it hit her forcefully. It was often too much to go so aggressive on her clit just like that, but this morning it felt so, so good. Needed.

Luna felt that she just needed another cum. That was all. Clear her head. She came up with wild and impossible fantasies all the time when she got in certain moods, and getting off usually made them go away. That was just how horniness worked.

Luna whimpered softly as she got closer and closer, her little noises mostly muffled by the shower. She leaned back heavily against the wall, trusting her legs not to give out entirely on her. Her tummy tightened a little, warmth and tingles running through her, then the explosion of a much needed orgasm giving her what she needed, making her happy, flushing out most of her nerves and leaving her much calmer afterward.

She hummed to herself as she dried off. Ryu was still in her head, but not in quite such an urgent way as before. That was something.

Still, as Luna took a look at herself in the mirror, she wondered what he’d think. She was pretty sure she knew. She knew how he looked at her with her clothes on, or with her tits out. If he saw her naked it’d be close to the same, only… more. So she hoped, anyway.

Luna wrapped a towel around her fresh and damp body. She padded out of the bathroom, intent on her own room to get dressed. The allure of Ryu’s room was too strong, though. She stopped at his door instead, barely clothed, mind whirling, excited at the possibilities despite just getting herself off.

She wasn’t going to do anything, though. Just say good morning. That was all.

Luna cracked the door open and peeked her head in. “Hey, you up? Or– oh!”

Ryu threw his covers back over himself. Quick, but not quite quick enough. Fast enough that Luna only got a flash instead of a full look, at least.

“Don’t you knock?” Ryu asked without any real malice in his voice.

“Were you masturbating?”

“… no?”

“You were, though.”

“Ok, yes.”

“Didn’t you just do that last night?”

“Yeah. And I was doing it this morning. So?”

Luna blushed. “Thinking about me?”

Ryu flicked his gaze away for a second, but it was quickly drawn back to his little sister, freshly showered and toweled. “Obviously.”

“Oh.” Luna fidgeted. “I had to this morning too,” she admitted. “I don’t usually have to again so soon.”

“Like… how often would you have to? On average?”

“I don’t know. A couple times a week maybe?”

“Not even once a day?”

Luna snorted. “That’s way too much.”

“Disagree.”

“Yeah, well, you’re a boy. It’s different. You get hard, you just want to touch it. I know how that works.”

Ryu laughed softly. “Not quite that simple, but… maybe not far off I guess.”

Luna shifted her weight. She was halfway in her brother’s doorway. She really should just leave again. Or go in. Standing halfway was just asking to get caught.

“Are you gonna keep going?” Luna asked.

“That’s the plan.”

“… after I leave?”

“Well of course. What kind of boy do you think I am? I’m not gonna jerk off in front of my sister.”

“Mmhm.”

Luna fidgeted some more and checked behind her to make sure the coast was still clear. She grinned wickedly, the grasped her towel and carefully lowered it to flash her tits without revealing anything more.

Ryu’s expression was exactly what she’d hoped for. He’d seen her tits the night before, but she wouldn’t have known it by the surprised and awed look on his face.

Luna stuck her tongue out, then arranged her towel and skipped away, only barely remembering to shut the door behind her. Let him jerk off to that. It was a much fresher memory for him.

Ryu groaned as Luna twirled around and left. That was so unfair. Leaving him with such a brief flash. Making him wonder about everything else under her towel. As though he wasn’t already far too obsessed with his sister while masturbating.

If she was going to do something like that, she could have at least given him a proper look. He’d seen plenty of her tits already, after all. Felt them up to his heart’s content last night. This was such a tease in comparison, just exactly the way she wanted.

Well… he didn’t have to let her get away with it.

Ryu hopped out of bed and stuffed himself into his boxers. He struggled into a shirt while moving, risking being in the hall with an obvious boner for the sake of exigency.

He barged in to Luna’s room just before she dropped her towel. She spun around, alarmed and confused for a brief second before taking in the sight of her chaotically dressed brother.

“What are you doing?” Luna asked, eyes firmly on the tent in Ryu’s underwear.

“What do you think?” Ryu said.

“I don’t– hey!”

Ryu casually flipped the front of Luna’s towel down, and she only just barely managed to hold the rest of it mostly in place. Her boobs were out, and the rest of her only scantily protected.

Ryu grinned and felt his cock twitch at uncovering his little sister’s chest again. How was she so damn perfect anyway?

“You can’t just do that whenever you want, you know,” Luna said, making no move to recover herself.

“Sure I can,” Ryu said. “I get one kiss, don’t I?”

“What does that have to do with my boobies?”

Ryu’s smile widened, matching the sudden increase in size of Luna’s eyes. He ducked his head, placing a soft hand on one of Luna’s breasts while approaching the other with his mouth. He kissed her tenderly just above her nipple, then trailed more kisses across her sensitive skin.

Technically speaking, it probably didn’t count as one kiss. Ryu knew that even as he did it. But it was pretty close. His lips stayed pretty firmly attached to Luna, and to her pretty tits.

“On my mouth!” Luna said, gasping at the sudden flood of sensation and arousal. “You get a kiss on my mouth.”

Ryu shrugged and kept teasing her with his mouth. He traveled from one breast, across the gap between them, and onto the other. He kissed them everywhere, tactically not focusing on the nipple, as per their previous conversation.

“This is cheating,” Luna whined, while simultaneously sticking her chest out and nearly losing her precarious grip on her towel.

Again, Ryu only shrugged and kept kissing. More like sucking, at times. And definitely some licking. But it could arguably be considered kissing. Luna didn’t dare think about what it would mean to call it anything different.

Although… he’d played with her tits a lot last night. Like a lot. And she’d happily let him. If she let this not count as a kiss… that would mean she’d still get one from him at some point. But it would also imply that her big brother could march in, pull down her towel or pull up her shirt, and suck on her boobies whenever he wanted. That sounded like a dangerous precedent to set.

But oh god was she tempted. The thrill and electric arousal dancing around inside her pushed her to just do it. Just let Ryu do what he wanted.

And then what? Could she… could she do stuff to him too then? Oh god, what would she do with that kind of power?

Ryu, temporarily oblivious to any thoughts milling through his sister’s head, felt an increasingly urgent need to get back to playing with himself. He wasn’t brave enough to do it right there in front of Luna, though making himself cum while sucking on her tits was tempting as all hell.

His cock throbbed in its constrained prison. He felt the dampness of precum soaking into his boxers. Only the continued siren song of Luna’s beautiful titties kept him from racing back to his room and sorting it out.

She was so soft, so delicious, so fresh and clean and adorable. Her protests all came with increasing physical touches to urge him on, making her words a bit ridiculous. Telling him to stop while pushing her chest to his face, and pressing a thigh to his erection, practically letting him grind on her.

Ryu finally raised his head, meeting Luna’s big, emotion-filled eyes.

“You got me all spitty,” Luna said.

“Sorry.”

Luna left her towel where it was, her breasts fully uncovered and shining from their recent oral attentions.

“You know what’s really unfair about that though?” she asked.

“I don’t suspect I do.”

“Now I only have one kiss left for the whole day. You went and used yours on my boobies. And that’s not even a proper kiss. One kiss all day, Ryu!”

“Sorry,” Ryu said again. “How about if tomorrow I definitely give you a proper kiss?”

“Promise?”

“I promise.”

Luna felt better immediately, already looking insanely forward to tomorrow, despite it being so early yet in today.

“You know I’m gonna have to masturbate again thanks to you,” Luna said. “Three times in, what, twelve hours?” She poked Ryu in the chest. “You’re a bad influence, big brother of mine.”

“You know I’m only gonna feel proud of that.”

Luna softened. “I know.”

She stared at him a moment, then launched herself at him. Luna’s arms wrapped around Ryu, she pressed herself close, including feeling his erection poking urgently at her. Quickly, decisively, perhaps recklessly, she kissed him.

Luna’s towel fell off in the process. She knew it. Knew she was pressing herself nakedly against her brother. He knew it too. His hands were on her back, down to her butt, squeezing, groping, then back up her spine. Ryu couldn’t see while they were kissing, but he knew her towel had come off.

Bad as it was, Luna loved it. Loved being held by Ryu without any of her clothes on. It wasn’t on purpose. Dropping the towel had been pure accident. But she felt so naughty, so appreciated, and so safe, held nakedly by her big brother.

Ryu enjoyed it too, from the opposite side. Luna all naked in his arms, kissing him fiercely, rubbing up on him.

Her tongue flashed over his and he met her, moaning into her mouth. Why did she do this to him? Of all the girls possible, Luna for fuck’s sake. They’d hardly even done anything. Just kissing, mostly. And playing with her tits a bunch.

Sure she was naked now. Naked and loving up on him. But he was pretty sure it wasn’t intentional, that she was just rolling with it. Like him, she probably didn’t know what to do about it once this kiss was over.

“My towel fell off,” Luna murmured, finally letting their lips separate.

“I noticed,” Ryu said.

“Close your eyes.”

“Why?”

“So you don’t see me.”

“I can feel you.”

“I know. Just… close your eyes.”

Ryu closed his eyes. It was hard to keep from peeking. Nearly impossible. He heard Luna scrambling, knew she wasn’t covered yet, knew he could probably get away with a quick look, but he didn’t.

“Ok, you can look.”

Ryu opened his eyes. Luna had her towel back around her, looking somewhat modest and innocent again. Her flushed cheeks and wild eyes gave her away, as did the oh-so-recent memory of her body against him.

“You know I’m gonna see you naked sooner or later,” Ryu said.

Luna blushed even redder. “Maybe.”

“Definitely.”

She bit her lip. “Jeez. You know I’m worked up already. Don’t have to keep it up.”

“I did notice,” Ryu said. “Didn’t think you’d use your kiss already.”

“Grr, me either. Now I’ve got nothing left to look forward to all day. Thanks for that.”

“Not my fault.”

“It is, though. You’re… you’re ruining me.”

“Oh?” Ryu raised an eyebrow.

“Making me lose control. No one does that to me so bad.”

“Just needed the right guy maybe.”

Luna crossed her arms and chewed her lip. “You?” she asked softly.

“I mean… not specifically. But maybe.”

“You’re gonna get such an ego on you. That you could do these things to me. Your sis-ter.”

Ryu considered the point. “Well… what about you doing these things to me?”

“That’s different. You’re hornier anyway.”

“Yeah, but… I’ve never felt like this.”

Luna’s heart beat harder in her chest. “Really?”

“Yeah. Really. Was it not obvious?”

Luna tossed her hair flippantly. “Well, you know, a boner’s a boner.”

“Not necessarily,” Ryu said quietly. “And it’s not all about the boner.”

Luna squeezed her arms tighter around herself. Her tummy was so fluttery, and she was desperately trying not to tremble.

“Tryin’ to sweet talk me now?” Luna asked.

“Nope. Just sayin’. I mean, I got what I was after already.”

“Oh really? Just my boobs is all you want, huh?”

“And your kisses. And other stuff. I just don’t really expect to get other stuff.”

Luna felt herself shaking despite her best efforts. “Like what other stuff?”

Ryu felt his face heat up. “I can’t say.”

“You can.”

“You’re my sister.”

“Doesn’t seem to stop you.”

Ryu stepped closer and put his hand under Luna’s chin, lifting it slightly, gazing into her eyes.

“You’re lucky I’m out of kisses,” he said. “Or you’d be in trouble.”

Luna let out a small whine. “You can kiss me.”

“I’m all out.”

“Nooo… maybe… maybe you can do one.”

“I can’t.”

“Just… kissing my boobies doesn’t count. Has to be my mouth.”

Ryu smiled. “Is that the rule?”

“Yeah. Of course. We get one kiss a day. But you have to do it right.”

Luna watched Ryu nervously. She didn’t know what she was doing. Not really. Only that she needed his lips on hers again. She needed it so badly. And she wasn’t sure Ryu would go for it. The rules were being stretched to breaking point. How long had it even lasted? A couple days? Brutal. How was it so hard to be good around her damn bro-ther?

“I better do it right, then,” Ryu said after what felt like an eternity.

Luna squealed as Ryu gently pushed her back, his lips meeting hers mid-stride, then the two of them tumbled onto her bed. Technically their kiss came apart mid-fall, but neither counted that. They picked right back up lying together, Ryu on top, heavy and warm on top of her, comforting and sensual.

Luna ran her hands up Ryu’s shirt. She wanted it off, but there was no way to remove it while they made out, and she wasn’t giving that up for anything.

Her towel came undone as they felt each other up and wiggled around together. She let it be. If it fell off again, then it fell off, and that was fine.

Ryu was aware of Luna’s towel falling open. First little flashes of her bare skin could be felt, then more and more. He waited patiently at first, but soon slipped a hand down to help her towel along. He cupped one of Luna’s tits in his palm and caressed it lovingly, all the while locking lips and dancing tongues with his cute and mostly naked little sister.

“Don’t stop,” Luna begged.

“I think I have to,” Ryu said regretfully. “I’m gonna cum.”

“More,” Luna insisted. “You can cum if you need to.”

“On you?”

“… if it happens it happens.”

“Dammit Luna.”

Ryu kissed her more aggressively. Definitely breaking rules by now. Unquestionably. But he couldn’t stop. Nor did Luna want him to. He could only imagine the look of disappointment and betrayal he’d get if he stopped kissing her now.

“Lemme get your shirt off,” Luna hissed.

“You’re really pushing this one kiss thing,” Ryu said.

“… shush.”

Luna was mildly annoyed at Ryu pointing that out. Mostly because it was totally true. The time it took to get his shirt off definitely meant they were starting another kiss after. But if he hadn’t said it, it would be much easier to pretend otherwise.

The other notable concern, not that Luna minded, was that Ryu got a full glimpse of her as his shirt came off. At least down to her waist. His lips curled in a possessive smile as his eyes bounced down her body, then back up. Her towel wasn’t even a consideration anymore as far as covering her.

“You’re so naked,” Ryu said.

“I know.”

“With your brother.”

“I knooowww.”

“Seems bad.”

“For who?”

Ryu shrugged. He didn’t have an answer for that. It seemed all good to him, actually.

He kissed Luna again, molding his body to hers. He lay atop her, holding his weight off somewhat at first, but she happily accepted him and he settled fully along her length.

Luna couldn’t have been more thrilled and aroused. With Ryu of all people. She was naked beneath him. It was crazy. But he kept kissing her, and feeling her tits, and grinding on her. She was lost to it. Just as happy and loved as could be.

“You’ve still got boxers on,” Luna whispered.

“I’m aware.”

“Should take ’em off.”

“Then we’d both be naked.”

Luna felt electricity inside, squirming at the excitement. “You say that like it’s a bad thing.”

“That’d be very close to having sex, Luna.”

Luna whimpered and kissed Ryu deeply. “Well obviously we can’t do that,” she said.

“Obviously.”

“But you need to cum. You don’t want to make a mess.”

“I’d make a mess on you in that case.”

Luna’s eyes fluttered closed and she struggled to breathe. “Yes,” she said faintly. “You would.”

Ryu grunted and thrust harder on his sister. He couldn’t take it. This was too much. Too horny. Too crazy. But oh god he wanted it. He wanted to cum on Luna. To make that mess he’d threatened. And she only encouraged him. It was so bad.

Luna struggled with Ryu’s boxers, tugging them down, feeling his cock suddenly slide against her. All slick with precum, and only getting more slippery as his precum smeared around on her skin.

Luna grabbed Ryu’s butt and urged him on. He was going to cum. He was going to cum on her!

Ryu grunted and tensed, trying to hold back. He couldn’t. Luna was too much. His own little sister. The way she just kept kissing him….

He wasn’t sure he’d ever felt more desired in his life. No one had ever been quite so manic about kissing him, nor wanted him to cum so badly that they didn’t care about the mess. Or actively sought it? Either way.

And he was right there with Luna. Wanting more of her. Wanting to give her what she wanted. Wanting to make her feel good.

But not sex. Fuck, not that. The temptation was there. Ryu kept his cock safely on Luna’s tummy so as not to accidentally do anything they’d both regret. The implication being that they wouldn’t regret what they were already doing.

“You can cum,” Luna said in a surprisingly gentle voice. “It’s ok.”

“Luna….”

“It’s ok,” she repeated, then kissed him again, going deep with her tongue right away.

Ryu was right there anyway. Whether she’d said anything or not. Since she had once again encouraged him, he was done.

Ryu took solace and comfort in Luna’s mouth as pleasure welled inside him, intense and almost painful, but releasing in such a rush of ecstasy as to be overwhelming. The constant reminder throughout that it was Luna he was cumming on. That she had halfway made him do it.

And it was such a mess. Ryu could feel it all over the both of them. A shared, slick, sticky disaster. Damn it felt good though.

“You came on me,” Luna cooed.

“You knew that was going to happen.”

“I did.”

“So now what?”

Luna shrugged. “I dunno.”

“I can’t get up.”

“Why not?”

“… you’re naked.”

“Right. Well… that’s fine.”

“You didn’t want me to see you like that,” Ryu pointed out.

“You got cum all over me. I think we might be past that.”

“Oh.”

Ryu sat up. His and Luna’s tummies were indeed quite messy. His eyes were only for Luna, though. Her shy, beaming smile, impish eyes, perfect, perky breasts, and her cute, slippery tummy that led to forbidden areas as his gaze followed it downward. Areas he couldn’t actually see while still straddling her, but could well imagine.

Luna didn’t let that stop her. Once Ryu was upright, she sneaked a hand under him and rubbed her pussy while her brother still sat atop her.

Luna bit her lip and fingered herself, feeling her own touch all the more intently for Ryu’s proximity and gaze. And, indeed, her first full body look at him without clothes on. It was intense and electric, so unreal and dream-like.

“Ryu?”

“Hm?”

“This is ok, right?”

Ryu cocked his head. “Little late to be asking that, isn’t it? You kinda told me it was.”

“I know. But just… your turn to tell me, ok?”

Ryu nodded slowly. “It’s ok, Luna. It’s all ok.”

Luna smiled at the reassurance, letting her eyes half-close and her gaze soften, still locked firmly on to Ryu. “Thanks.”

“You do things to me, Luna,” Ryu said, lazily running his fingers up her soft skin, deftly avoiding cummy swathes.

“Oh?”

“I don’t quite know what to make of that.”

“You’re supposed to be telling me it’s ok!”

“It is,” Ryu said soothingly. “It’s me and you.”

“Yeah,” Luna breathed. “Me and you. That’s right.” She eyed Ryu cautiously, needing more from him, but not sure if she dared take things further. How could she dare? And yet, how could she not? “I love you,” she said, trembling, feeling butterflies inside, fighting a painful need in her clit.

“Yeah. Me too, Luna.”

“No, I mean, I think I love you, Ryu.”

“Like….”

“Like how the fuck am I supposed to find anyone else like you? Like… like why can’t I love my brother anyway? Who made that rule?”

Ryu felt himself shaking, very much the same as Luna. He hardly dared touch her, knowing he’d give away some feelings in doing so. But he couldn’t bear not to touch her.

“I don’t know,” he said. “I don’t have any answers at all for you right now.”

“Jeez. And after you already cummed on me, even. Horny again already?”

“I don’t think it’s about being horny, Luna. I mean… parts of it are. Obviously.”

“Obviously,” Luna agreed, still rubbing her pussy.

“Just, like… you confuse me. You know that, don’t you? You’ve been turning some things in my life all upside down.”

“You started it.”

Ryu grinned crookedly. “I guess that’s true. Then… maybe this started a ways back. I don’t know when.”

“Me either,” Luna said. “I can’t imagine when I ever would have had feelings like this, but… it’s so easy to just let them happen.”

“It really is.”

“I love you, Ryu.” Luna smiled. “It feels so good just to say it.”

“Goddamn, Luna. I… I love you too.”

Luna whimpered and threw her head back, trying desperately to keep some order to the way she was rubbing herself. She could cum. Just a little more….

“Again.”

“What?”

“Say it again! Please?”

Ryu leaned down, knowing full well what he was doing, but unable to help himself. “I love you,” he repeated, then kissed Luna softly, tenderly, lovingly on the lips. Showing affection both physically and verbally. His brotherly love for her.

Luna came. The most perfect cum she could imagine. Well… almost. Perfect enough.

Ryu’s touch, his kiss, his love. Her poor little pussy exploded in happy pleasure, making almost as much mess of her sheets as Ryu had of her tummy. Her legs tensed and shook and her toes curled. She moaned and clung to Ryu, needing his mouth on hers for as long as possible. Needing something to hold on to while she drowned in her own physical pleasure and a storm of emotional connection and adoration.

Too much. Way too much all at once. But so very perfect.

Her perfect big brother. Who could have suspected?

****

“You know, we should clean up at some point,” Ryu said.

“I know,” Luna said. “But I want to just lie here.”

“That’s all we’ve been doing for… how long has it been?”

“No idea.”

“I think I’m super late for work.”

“Probably.”

“You don’t care at all, do you?” Ryu accused.

“Nope,” Luna said.

“Ah. Well… me either, actually. Though I should probably shoot a text and hope I’m not in massive trouble over it.”

“Probably.”

“… you’re not gonna let me go, are you?”

“Not without a fight.”

“‘K.”

Luna sighed happily as Ryu failed to move. “You know I just showered and everything. Now I have to clean up again.”

“In comparison, I think mine’s a bigger bother.”

“Wasn’t a competition.”

“Just saying.”

****

Ryu and Luna didn’t make much progress on figuring things out for a few days. Which was fine with them, really. They probably needed to make some decisions, but it was so much easier and more fun just not to.

Ryu found his days obsessed with Luna, and she right back at him. The sort of obsession that comes of seeing each other naked, and cumming, and lots and lots of kisses. More than that, though, even just regular time spent together had new meaning. New, beautiful, deeper meaning.

“What’s going on with the two of you anyway?” Will asked one day.

Ryu startled and tried not to panic at his father’s question. “What?”

“You and Luna,” Will said. “We knew your sister was seeing someone she didn’t want us to know about, but now the two of you are acting all secretive and happy.”

“Hush, darling,” Adrianna said. “You shouldn’t just give away Luna’s secrets like that. She talked to us in confidence.”

“I’m not giving anything away,” Will protested. “They’d tell each other stuff way before they’d tell their poor old parents. Ryu probably knows who Luna’s seeing, don’t you?”

“I’m uncomfortable with this,” Ryu said honestly.

“Don’t worry about your father, dear,” Adrianna said, rolling her eyes. “Luna’s on a journey of some kind. And maybe it’s a good idea and maybe it isn’t, but that’s not for us to decide for her.”

“Oh,” Ryu said. “Well… good, then.”

“It’s infuriating not to know,” Adrianna admitted. “But we’re going to respect her privacy, aren’t we?” she asked, looking meaningfully at Will.

“Yeah, yeah. Privacy,” Will grumbled. “Overrated!”

“You don’t think so when its ours we’re talking about,” Adrianna said with a sly smirk.

Ryu’s eyes flashed. “Please tell me that wasn’t a hint of something I don’t want to know about.”

“Ok,” Adrianna said. “I won’t tell you.”

“Aaannnd I’m out,” Ryu said. “I’d say this exchange was fun, but….”

“Urgh, you always ruin my interrogations,” Will said as Ryu retreated.

“Darling, you shouldn’t be interrogating our children.”

“Well if they wouldn’t keep secrets….”

“It’s what children do, I think you’ll find. Very healthy for their development.”

“Then I’m helping them hone that development.”

“Yes, darling, of course you are.”

Ryu shook his head as he got safely out of earshot. His parents were cool, generally, but with a knack for being absolutely mortifying when they so chose. Often not for reasons they’d ever consider.

How red had he gotten during that brief talk anyway? Hopefully not bad enough to give anything away. He and Luna needed to be more careful, it seemed. And yet….

Ryu sighed wistfully just thinking about Luna. How could they be more careful? They were doing all the could to be sneaky while still getting their time together they so desperately needed.

It just wasn’t fair how complicated loving his sister was.

****

“I don’t think we need to worry,” Luna said.

“Oh you don’t?”

“Nope.”

“So even though Mom and Dad fully know we’re both seeing someone–“

“They suspect,” Luna corrected. “They don’t actually know anything.”

“Leaving that aside for the moment… we also spend a lot of time in compromising positions. We could be caught at basically any time.”

Luna frowned. “How do you mean?”

“I mean we’re sitting outside, and you’re in my lap again with your shirt up over your boobs and keep teasing me like you’re going to kiss me.”

Luna grinned. “Well it’s one of my favs. And not just because I could use a little tanning on my boobs.”

“I am aware. I love it too.”

“You love my boobies,” Luna corrected.

“I do,” Ryu said. “And I love you. Possibly in that order, as you pointed out.”

“Hey! No, I never… you have to love me first, then my boobies. In that order.”

“I shall do so, then.”

“Good.”

Ryu took the time to kiss Luna’s tits, trailing kisses across them with all due brotherly care.

“I’m right there with you,” Ryu said. “Don’t get me wrong. I don’t want to stop anything we’re doing. Just… how do we not get caught?”

“You think I know?”

“No. I’m just asking.”

Luna tangled her fingers in Ryu’s hair and encouraged his face back to her chest. She sighed happily as he kissed her tits some more.

“Ok, so like, if we had to… we could stop with the inappropriate stuff,” Luna said.

“Uh….”

“Just if we had to, I said. Not that I want to. But… I don’t know, Ryu, you make me happy. I want the sexy stuff, but it’s not as important as you are.”

“Luna….”

“… I didn’t say you had to stop kissing me.”

Ryu grinned wickedly, looking up at Luna, abandoning her tits for the moment. He went for a proper kiss instead, caressing her lips with his, starting tender and affectionate. He went deeper, sought out her tongue, poured his love into her.

The kiss, as often happened between them, lasted as long as their breath held out.

“Well, that’s my one for the day,” Ryu said.

Luna squirmed in his lap. “Remind me why we’re still doing that? It’s not like we even stick to it most of the time.”

“Because that’s the rule. One kiss a day.”

“I don’t think I like that rule anymore.”

“Gotta have rules. Where would we be otherwise?”

Luna pouted. “But I already used my kiss today.”

“I know.”

“What am I gonna do, wait ’til tomorrow?”

“Seems unlikely, doesn’t it?”

“Maybe… maybe I just find something else to kiss.”

Ryu groaned at the look in his sister’s eye. The fact that only kisses on the mouth counted, as per their increasingly stretched rule, forced them to be inventive. Which was, honestly, one of the best reasons for even pretending to stick to their ‘one kiss.’

Luna did, indeed, get inventive with it. She kissed all along Ryu’s neck and collarbone, up to his ears, then down his chest. She took his shirt off to make things easier, then started undoing his pants as well when she got low enough.

“Where you goin’, Luna?”

“You’ll find out,” Luna teased.

“… is it in my pants?”

“Maaayyybe.”

“I only ask because you seem to be trying to get in pants, is all.”

Luna nodded. “And if you’d just help out for a second, I’d have them off already.”

“Remember what I said about compromising positions?”

Luna waved Ryu’s concern away. “You worry too much.”

“I don’t. Usually you worry more. Just… I don’t know, Mom and Dad are onto us. Kinda. I really don’t need them finding out about this.”

Luna looked up at her brother from her knees, beaming as she got his pants down and his cock freed. She stared up at him as she took a gentle hold of his erection, leaned in, and gave the softest of kisses right underneath the head.

Ryu groaned and his cock twitched in Luna’s hand. “That’s where you wanted to kiss, huh?”

Luna nodded. “Mmhm!”

“… well you can do that some more if you like.”

“What makes you think I didn’t just want one?”

“That wouldn’t be nice.”

“I mean… really I should put your penis away before we get caught.”

“Lunaaa.”

“Yes?”

“Play nice.”

“Sooo… you want another kiss?”

“Yes please.”

Luna nodded and kissed Ryu’s cock again, just down from the first one. Again, she gave him only one, then just looked at him, still holding and gently teasing his shaft with her fingers.

“Are you going to make me keep asking?” Ryu asked.

“Depends. Do you want your sis-ter to keep kissing your penis?”

“Unf. Goddamn, Luna. Seriously.”

Luna quite enjoyed being able to drive her brother crazy like this. She was getting really good at it, she felt.

Ryu quite enjoyed it too, for that matter. Enjoyed it enough to put thoughts of their parents aside and have eyes only for Luna, kneeling before him, looking a perfect mix of falsely innocent, coy, and deviant. A look his little sister shouldn’t be able to pull off so well.

Luna leaned in like she was going to kiss him again, then flirted away, so close that he could feel her breath on his sensitive skin, but not close enough to touch.

“Seriously,” Ryu repeated.

“Yeah, seriously,” Luna said. “What do you want? You gotta tell me.”

“The same thing I want all day, every damn day. More kisses from my little sister.”

Luna whimpered softly at hearing Ryu say it out loud. She had to reward him with another naughty kiss for that. Had to. Then another one.

Ryu sighed happily as Luna showered his cock with kisses. He tousled her hair adoringly as she kissed all over. All along his shaft, the head, and down to his balls even. All the illicit attention a boy could ask for.

“Creativity is good sometimes,” Ryu murmured.

“Like when it gets my mouth on your dick?” Luna asked.

“Yeah. Kinda like then.”

“That’s a baaaddd big brother.”

Ryu bit his lip and declined to argue that, in fact, Luna was the one kissing his cock all over. It seemed counter-productive.

Luna enjoyed the control she had over Ryu, while also making him feel good. Just kneeling in front of him, giving him her most sultry little sister eyes, and smothering his cock with kisses. It was fun and effective, and made Ryu twitch and leak precum all over.

A lovely way to while away a late sunny afternoon into the evening. The question was how long she could go before Ryu demanded more of her. Or, indeed, before she felt a need to do more than just kisses.

Ryu got wiggly in his seat. Luna’s teasing was getting to him, in the very best possible way. And the way she kept looking at him, even through all those kisses….

She couldn’t maintain eye contact for every angle. Not at all. But boy was she doing her best.

There were ways a brother never expected his sister to look at him, and Luna had been getting very good at those exact ways lately.

“Lunaaa….”

“Hm?”

“Can you… maybe suck me a little?”

Luna gasped. “You want me to suck my brother’s pe-nis? That sounds baaaddd.”

Ryu groaned. “You’re killing me, Luna.”

“Kisses are one thing, but sucking? I mean–“

“Absolutely killing me. This act of yours–“

“You love this act of mine,” Luna said, grinning devilishly as she gave Ryu another tactical kiss on the tip of his cock.

“… true. But… please? I’ll kiss your pussy for you.”

Luna closed her eyes and let a delightful shiver run through her at the brotherly promise. “Hard to say no to that,” she admitted softly.

Luna kept kissing Ryu, but started sucking on him a bit instead of pulling away immediately. She let her sucking get longer and harder, still teasing her big brother as only a little sister could. Eventually she gave him what he actually really wanted, and took him in her mouth.

Ryu moaned in the sexiest way for her as she bobbed her head on his cock, working him deep. He had such an amazing flavour from all the copious precum.

Ryu was putty for Luna. She played him so exquisitely, building him up, making him helpless. He sent affection back, stroking her hair, meeting her eyes when she looked up at him. He felt such a mix of love and lust for his little sister. The sorts of things that he should never have felt, but were becoming all too common. But it all felt so right, though.

“Luna?”

“Hm?”

“I’m gonna cum.”

Luna’s nostrils flared and she sucked Ryu a little harder, working him toward completion.

“Where do you want me to cum?” Ryu asked.

Luna’s eyes rolled back for a moment, and she just kept aggressively sucking. Soon enough she wouldn’t have a choice.

But Luna knew where she wanted it already. She just didn’t want to take her mouth off her brother long enough to tell him.

As soon as Ryu started cumming, Luna pulled her head back and aimed at her tits. Getting them all covered. Just the way she knew Ryu would find exceedingly hot, and would do such wonderful things for her already well soaked pussy too.

Luna got a bit of a taste of Ryu’s cum before she pulled off, and she left it on her tongue until he was all drained.

Ryu experienced the tingles and surges of pleasure that came with orgasm, plus all the added benefits of Luna doing it. It was more intense, for sure, from Luna’s lips and tongue at first, trailing away to her soft, sisterly fingers pumping him dry. The after-effect of seeing her douse her own tits in his messy cum was a lovely bonus.

Luna nuzzled Ryu’s cock after and gave it a few more small kisses until he couldn’t take it.

“Ok, ok, I surrender,” Ryu said.

“Oh good,” Luna said. “‘Cause you owe me some kisses.”

“On your pussy.”

“On my pussy. Obviously. Already kissed me properly. Can’t do that any more.”

“No. That would be bad.”

“Exactly.”

Ryu and Luna switched places, including Luna ditching her bottoms in the process.

Luna was nearly naked now, same as her brother, and the sun felt good on her exposed skin. She was getting a real taste for nudity outdoors. Something she wouldn’t have expected of herself. Then again, until she and Ryu started messing around, there was no way she would have dared take her clothes off in front of him like this.

Luna tensed with anticipation as Ryu knelt between her legs and gently pushed them wider apart. She drew in a breath as she watched him get closer and closer, then shivered and made an embarrassing little squeak as he actually kissed her pussy.

“Again!” she commanded.

“Really? More than–“

“Again!”

Ryu grinned and kissed Luna’s pussy again. He started slow, but was soon showering her with naughty kisses. Once he had her taste, he couldn’t stop. His kisses got deeper, using plenty of tongue, becoming more licking than anything else.

“Lick meee,” Luna insisted.

“I am.”

“S’niiice.”

Luna cooed and encouraged Ryu, loving every second of his oral attention. He could make her feel so damn good. Just by being her brother. And especially while doing unbrotherly type things.

Ryu kissed and licked Luna to orgasm. He made her cum in that delightfully cute way that he loved. She moaned his name and caressed his hair, even squeezing his head between her thighs as she came.

Ryu gave her soft, slow kisses as she released him. Bringing her down gently and with all due adoration.

“I love how you kiss me,” Luna whispered.

“Proper kisses, or….”

“Both. Obviously both.”

“Too bad I have no more proper kisses for you.”

“I know. It’s not fair. I–“
