"Did you want something?" he asked after an awkward moment of silence.
"Oh, right." Cat snapped back to reality and padded closer. "I just wanted to see if you were ok. After, you know, this morning. Kinda feel like you've been avoiding me."
"I kinda have."
Cat looked disappointed. "Oh."
"We needed a little space, is all."
"I see."
"Stop looking sad. You know things got too weird this morning." Laine rubbed his face. "And you know, it would have been nice if you didn't put your cuffs on before coming to talk."
"Yeah, I didn't mean to. Mags kinda just did it. I think she thinks that I like it better when someone makes me."
"Don't you?"
Cat blushed and looked down. "Well I didn't say she was wrong."
Fuck she was adorable with her hands restrained, her skimpy night outfit, and that cute blush. And sexy. Adorably sexy. Laine hoped some of that was just his interrupted masturbation session talking.
"Maybe we could talk more tomorrow?" he hinted in an attempt to get her out of the room.
"Yeah, maybe," Cat agreed. She did not, however, make any move to leave.
"Did you need something else?" Laine asked, hoping desperately that she didn't.
"Um... like... were you jerking off just now?"
"I'm not answering that. That's not even... it's not... just... please go now."
"I mean, I know you were," she continued as though he hadn't spoken.
"You're just making this worse for me. You know that, right?"
"Sorry. Just... were you thinking about me?"
It wasn't an accusation. Laine could tell by the tone of her voice. If anything, it sounded like a legitimate question. Like Cat was really curious whether her big brother was jerking off while thinking about her. That failed to surprise him as much as he might have liked.
"If I say yes, will you leave?"
Cat's eyes lit up. "Really?"
"Oh my god. Don't you dare be excited by that."
"I'm not."
"You are. Your eyes are practically glowing."
"Oh." Cat, with conscious effort, reset her expression to something more neutral. "How's this?"
Laine rolled his eyes. "This is why I was avoiding you. Things are getting seriously confused."
"They're not." Cat fidgeted, then stepped closer still. "I just... I maybe kinda like that I'm not the only one having weird thoughts. Bad thoughts."
"Well--"
"And I'm actually really glad that you're turned on--"
"Cat!"
"--by what happened instead of, like, being grossed out. That would have been way worse, I think."
"It would have been a more proper response."
"I guess. But it really woulda sucked if you'd, like, seen me piss myself and then been utterly disgusted by me and not wanted anything to do with me and--"
"Jesus, Cat. Slow down."
"Sorry."
Laine sighed. He patted the bed next to him, having given up on a speedy end to the conversation. "Here. Sit down."
"'K."
Cat plopped down semi-gracefully next to her brother. She didn't give any indication of minding that he was still blatantly concealing an erection. Granted, it had softened a bit, but still.
She looked far too innocent for what went on in her head these days. That was probably part of the problem he'd been having. He could look at her and see his baby sister, or he could see a sexy little minx who was grappling with her sexuality and slowly winning. It confused him that she was, in fact, both of those girls.
Now he had to navigate between those two distinct facets of her being without crashing.
"So," Laine began. "You know handcuffing you was never meant to be... sexual... or anything."
"Yeah, obviously. That would have been weird."
"Ok, well it was kinda weird anyway when it started being something you enjoyed in that kind of way."
Cat shrugged. "It kinda was right from the start, if that helps any."
"It doesn't. Either way, me and Mags thought we might need to, like, help you tone it down a bit. And that didn't work out very well."
"Sure."
"And now we're here...."
"Yep."
"And I kinda just don't know what to do with you at this point. It wasn't even so bad when you were parading yourself around every now and then, because at least I could almost pretend like I didn't know what you were doing. But actually being involved... it's tricky."
"I really didn't mean for this morning to happen," Cat said. "It was an accident. In more ways than one."
"Yeah, I get that. But what about right now? I mean, you know I was jerking off, yet you're still here. And trying to get details about what I was thinking about no less."
Cat at least had the grace to look slightly bashful about that. "I guess I'm still a bit confused about this morning too. 'Cept in a different way from you, I think." She looked at Laine with big, worshipful eyes. "I thought it was gonna be basically the worst moment of my life, at the time."
"Oh come on. It wasn't that bad."
"Maybe. But a big part of what bothered me was that I thought you were gonna think I was such a baby for pissing myself like a little kid. And you didn't. You actually got crazy turned on."
"Well I wouldn't say--"
"It meant a lot to me, is what I'm saying. So if you were still thinking about it, that's pretty much ok with me. That's all."
"Uh... I think this might be some more of things getting confused. You shouldn't really be encouraging me to think about you that way."
"Duh. I know that." Cat shrugged, a movement hindered slightly by her restrained arms. "But I'm really starting to like the idea, and nothing you say is really gonna change that."
"That's... probably true." Laine slumped in defeat.
"You're still gonna feel bad about it though, huh?"
"Yup."
"Well, hopefully you get over that. I absolve you of your sins, if it helps any."
"It doesn't."
Cat nodded and hopped off the bed. "Well, have fun masturbating anyway. I know I will."
Laine couldn't help himself. "Cat?"
She stopped at the doorway. "Yeah?"
"How exactly do you masturbate with your hands behind your back?"
She grinned a teasing little smile. "Curious, huh?"
"Despite myself, yes."
"You could come see, if you wanted."
Laine sighed. "Yeah, I thought you might say something like that. Good night, Cat."
"But really, if you--"
"Good. Night. Cat."
She giggled. "Night, Laine."
Laine waited to make sure she was really gone, then shut the door and lay back on his bed, picking up where he'd left off. Thanks to Cat's newfound assertiveness, his need to get off really hadn't gone anywhere, it had just changed shape a little.
He couldn't believe he'd inadvertently given her a new confidence in flaunting her sexuality around him. That wouldn't have been his first guess as to the result of the bathtub debacle. Then again, he'd come away from it as horny as she had, so he could kind of understand her point of view.
It would have been nice if neither of them had reacted like pervy weirdos. That was all.
****
Catria couldn't believe her own boldness any more than her brother could. She really hadn't intended to interrupt him jerking off, nor show her interest in it, but she had. She'd only meant to make sure he wasn't having serious regrets about that morning.
The brief flash of his hard cock before he'd covered up and the guilty look in his eyes had told her all she needed to know. He was thinking about her. She made that happen.
Catria had felt something very different from usual; warmer and fuzzier, but no less exciting than the shame, guilt, and embarrassment she was used to getting off to. It made her feel incredibly sexy that she could make Laine so horny. Her own brother.
She'd half hoped he'd take her invitation and come watch her while she rode her vibrator after their conversation. She was pretty sure he wouldn't, but just the chance that he'd burst in at any moment made her all the hotter.
She woke up early the next morning. She was splayed every which way, blanket kicked off the bed, vibrator still right in the middle of the bed. Apparently she'd fallen asleep pretty hard.
Still feeling a bit naughty, Catria got out of bed and snuck into Laine's room. He was on his back snoring away, chest partly uncovered by his uneven blanket. She wondered if he was naked underneath, but didn't quite dare to find out.
Instead, she balanced on one leg and dragged his covers down with her other foot just enough so she could slip in underneath. She curled up next to her brother and drifted off again.
She only dozed this time, and so was awakened almost immediately when Laine started moving. He was being quiet and moving slowly, clearly assuming her to still be asleep. He carefully climbed over her to get out of bed.
In the process, Catria discovered that he was, indeed, naked. His semi-hard cock dangled near her face for a second before he was across her. She forced herself not to roll over, even though it meant she couldn't see anything.
There were sounds of Laine dressing, then she was picked up and cradled in his arms. She kept her eyes closed for the familiar trip of being carried back to her bed.
She was deposited gently on her mattress, and she risked opening her eyes to slits. Laine reached across her and grabbed her vibrator. She felt a nice little pang of embarrassment as he examined her toy before then setting it on her dresser.
Next he took her wrists and unlocked her cuffs, setting her arms free for the remainder of her 'sleep.' She wasn't quite as into that, but she left her arms limp and continued acting unconscious.
There was a brief lull in activity. Catria strained her ears, trying to figure out why Laine wasn't moving. Then, surprising her enough that she almost jumped, his hand went to her butt and gave it a quick squeeze.
Luckily he didn't notice the uncontained grin on her face as he draped her blanket over her and tucked her back in.
****
Part Three: Cat's Out Of The Bag
****
Catria spent the next several weeks exploring her new boundaries. She was totally free to walk around the house in her cuffs whenever she wanted, that much was clear. But there were other things that were a bit less certain.
Sometimes she snuck into Laine's bed. He didn't complain much about it. She wasn't sure if he knew it was deliberate now or not. Either way, she usually just got dumped back in her own room with very little ceremony.
Every now and then she got a bit of a fondle while she feigned sleep. Those mornings were her favourites and tended to leave her in a very good mood the rest of the day.
She knew that she shouldn't really let that sort of thing keep happening, that it should remain a fantasy only, but it was just who she was. She liked being attractive to her brother, and she really, really liked when he couldn't help himself around her.
Catria's schoolwork improved with her change in attitude, and she spent more time with her friends as well. Being able to be happy and free at home in a way she'd never been before made everything better. Granted, she still fell into naughty daydreams fairly often, but she was able to work around them.
She came home one evening to a house that at first appeared deserted. That was strange, though not totally unheard of.
Being fairly hungry by then, not having eaten since lunch, Catria went to the fridge and discovered a plate of supper thoughtfully left for her by Maggie. She heated it back up in the microwave, then wandered to the living room.
She heard sounds as she approached. Someone must have been home after all and just hadn't responded to her arrival.
Laine was slumped lazily on the couch, game controller in his hands, eyes glued to the tv. He was playing a game that Catria didn't immediately recognize, not that that meant much.
"Oh. Hey," Laine said, barely glancing at her.
"Hey yourself. Mags gone out?"
"Yeah."
"Cool."
Catria sat down and balanced her plate on her lap. She ate in small, careful bites so as not to drop anything. She watched Laine's game progress as a substitute for a show or movie.
"This game involves an awful lot of watching that dude's butt," she remarked.
Laine turned his head a few degrees toward her. "Is that a hint that you want me to stop playing?"
"Not at all. I kinda like watching you play. You don't do it as much anymore."
"I guess."
"And I'm not opposed to watching cute guy butts running around and climbing and shit."
"Of course you're not."
Laine's character didn't move for a moment. He seemed to be waiting for something else, but when nothing was forthcoming, he resumed play.
Catria kept watching while slowly working on her dinner. She actually quite liked playing games vicariously through her brother. He was better at them than she was, and it was a lot less stressful than trying to tackle them herself.
"So are you playing Mr. Tomb Raider or something?"
Laine paused the game. "What?"
"Well I don't know. Like, you're climbing a lot, and then shooting some guys. Like Tomb Raider, right? Except you're a dude."
"So you think it might be called Mr. Tomb Raider?"
"I dunno. Maybe? How'm I s'posed to know what his name is."
"Hang on, do you think Tomb Raider's main character is actually just called Tomb Raider?"
"Um... is she not?"
Laine sighed. "I just don't know where I went wrong with you sometimes." He started playing again. "Lara Croft. Not Mrs. Tomb Raider."
"Oh, yeah. I think I knew that."
"And this would be a totally separate game series anyway. Uncharted. Which, come to think of it, is not dissimilar in some ways." He nodded to the screen. "And that would be Nathan Drake, not Mr. Tomb Raider."
"Well how'm I gonna know that?"
Catria finished eating and set her plate aside. She rearranged herself, tucked her feet snugly up under her butt, then leaned against Laine and rested her head on his shoulder.
"We really could watch a movie or something if you want," Laine said.
"No. I'm good."
"You sure? You're getting awfully cozy just to watch me derp around."
"I like being cozy. And I get the feeling like you could use some cuddle time."
"And why's that exactly?"
"I dunno." Catria shrugged. "I guess partly it's just 'cause you don't play games much anymore except when you had a bad day."
Laine was quiet a moment. Then, "well, it was kind of a rough day at work."
"Thought so."
"But I'm fine. You don't need to worry about me or anything."
"Who's worried? I just want to help my bro out. That's all."
"If you say so."
Catria really had only intended to snuggle, but gradually got more playful. It was kind of fun nuzzling and tickling her brother while he was trying to focus. He swatted at her occasionally and grumbled about her behaviour, but she could tell he was enjoying it too.
"You're really just not gonna let me play, are you?" Laine finally asked.
"I'm not doing anything," Catria protested while running a fingertip across the top of his ear.
Laine pushed her arm away. "Ok. Fine. You win."
"I do?"
"Yeah. Go bring me your handcuffs."
Catria perked up immediately. That hadn't been her intention, but if Laine insisted....
"Ok!"
She bounced to her feet and skipped happily off to her room. Time for some real fun.
She decided to change before returning. It probably wasn't what Laine meant, but there was no point passing up the opportunity. Besides, she'd gone shopping with a friend a couple days ago and she had some new underwear she wanted to try out.
Catria pulled one of her new pairs of panties out of its drawer. Up until now, her panties had mostly been functional rather than sexy. Some were cute, sure, but they all covered her naughty bits pretty effectively. These ones less so.
Her heart beat faster even just from staring at the panties. She hadn't quite been brave enough to just start wearing them around the house. They weren't quite a g-string, but they had very little material in the back. She'd be showing off most of her butt.
Trembling slightly with contained nerves, Catria stripped naked and slid into her tiny new panties. They fit beautifully. Her friend had assumed they were for a secret boy since they were skimpy and impractical for much of anything other than looking hot. Said friend had been basically correct, but would never have guessed who the lucky boy was.
Next she pulled out a new camisole that had also been purchase with seduction in mind. Unlike her others that were simply comfy night clothes, this one hugged her body and showed off some cleavage.
Catria couldn't be sure how Laine would react to her outfit. She hoped he'd like it. In fact, she hoped he really, really liked it. She'd just have to test it out and see what happened.
She walked slowly as she returned. She wanted to make sure Laine got a look at her as she approached. He just glanced at first. Then almost immediately took a longer second look.
"You didn't have to change for bed," Laine said.
"Well I might as well. Otherwise I'd have to get uncuffed and recuffed, and it'd be a whole thing."
"Uh... ok."
Catria finally permitted herself a broad smile when she handed over her cuffs and turned around. She was pretty sure he'd liked the view of her front side, and was even more certain about the back. Even though she kept her eyes forward, the long delay heavily suggested that he was staring at her barely covered ass.
She waited patiently, unmoving, allowing Laine to take all the time he need to stare at her butt. Eventually he jerked into motion and snugged her handcuffs into place.
"You like my new panties?" she asked as they sat back down.
Laine gave her a look. "I kinda had a feeling you wore those on purpose," he said.
"Mighta. What do you think?"
"I can't help feeling like you already know the answer."
"Maybe. I wanna hear you say it."
Laine fiddled with his game controller, and Catria thought he wasn't going to respond. She kept staring at him anyway.
"Fine," Laine said. "They look good on you."
"Really?"
"Of course really."
"Then why don't you sound happy about it?"
"You know why."
"Because I'm your sister?"
"Yeah."
"And you really like my butt, but you don't like admitting to it?"
"... yes."
Catria smiled and settled back in next to Laine. "Well I like hearing you say it anyway."
"Yeah. I got that."
Laine resumed his game. Catria behaved herself and simply cuddled and watched his on-screen character.
"It's not fair, you know," Laine said.
Catria frowned at the apparent non sequitur. "What's not?"
"You enriching your ass to weapons-grade like that. Not fair."
She giggled. "Ooh, I like that. Weapons-grade butt."
"Thought you might."
Catria boosted herself up a little awkwardly without her hand and kissed Laine's cheek. "I really appreciate it," she said softly. "I know you don't like admitting things like that."
"Seems like I might have to get used to it." He smiled crookedly. "It helps that you don't seem to mind me thinking about you that way."
She considered the point. "I guess I should, shouldn't I?" She shrugged. "That's just not how I turned out."
"No. Indeed it isn't."
Laine returned his focus to his game. He glanced sidelong at Catria from time to time, but mostly she was just a spectator.
She was content with her role this time around. Now that she had her cuffs on, clothes half off, and some nice snuggle time, she was pacified. All felt right in her world. It was probably, she suspected, similar to how dogs viewed lap time.
Actually, speaking of lap time, her legs were getting a bit tired of being scrunched under her. She repositioned to stretch out and use more of the space available to her on the couch. Her head, somewhat because of her line of thought, ended up on Laine's lap.
Laine had to hold his controller a bit differently and not rest it in his lap now that there was another occupant, but he didn't complain.
Catria was nice and comfy, and pretty well settled in. She let her eyes fall partly closed, just relaxing and keeping a lax eye on the proceedings on the tv screen. She wasn't expecting anything to happen, and that was fine with her.
However, something did happen. Her eyes flashed wide open in delighted shock as Laine's hand came to rest on her breast.
A cutscene was playing in his game and he didn't need both of his hands at the moment. That was a small thought inside Catria's head. The big thought was she was actually straight up getting fondled by her brother.
He wasn't even looking at her. Just resting his hand on her chest, idly flicking his thumb across the small bump of her nipple.
She forgot to breathe for a moment, though physiology caught up with her quickly enough. She was so stunned she didn't know what to do. Even though he snuck a feel sometimes when he thought she was sleeping, she hadn't been at all prepared for the same thing when he knew she was awake. It had a whole different set of connotations.
It was like he'd decided he had free rein of her body and he might as well make use of it. If so, he wasn't wrong.
The cutscene ended, and Catria let out a small, imperceptible sigh of disappointment as Laine's hands went back to his game controller. She hadn't dared move or say anything while he was touching her just in case she scared him off. Little leftover tingles danced through her body while her breathing and heartbeat slowed back down.
She waited impatiently for another break in the action, becoming somewhat fidgety when it didn't happen right away. She wanted more attention, but was in a tricky position of not being able to say or do anything about it.
Her restraint was eventually rewarded. The next chance he got, Laine was playing with her tits again. It was still little more than idle stroking and teasing, but he was growing perceptibly bolder.
Catria was getting thoroughly horny. Not only was she getting some open, albeit intermittent, action from her brother, but he was really just using her as a toy. Something to keep his hands busy when he wasn't playing his game.
That lack of being treated as a person, let alone his sister, was thrilling in ways she didn't fully understand. She knew it was only because she'd goaded him into it, but it also wasn't too much of a stretch to pretend he'd cuffed her and forced to lie there and be his plaything. Her pussy burned as her mind ran wild with the imagined scenario.
In some ways, her cuffs represented a surrender of control to her brother. There was more to it than that, but it was a convenient simplification. Viewing her current easy acceptance of playing a sex toy as an extension of the fetish she'd previously figured out helped her wrap her head around what she liked about it.
"Hey, Cat?" Laine said.
She startled a bit. She'd been lost in her own little world, luxuriating in alternating states of delicious teasing and aching denial.
"Yeah?" she said.
"Would you mind going to get me some water?"
"Oh. Uh... sure."
"Thanks."
Catria reluctantly left her cozy spot and padded out of them room. She'd forgotten all about the skimpiness of her panties. Only a brief image of Laine staring at her ass in her peripherals as she turned the corner reminded her what kind of show he was getting when she walked away.
Goddamn she wished she could stick a hand down her panties and relieve some tension. But she couldn't. And the fact that she couldn't made her need all the stronger.
She tried to concentrate on completing her somewhat difficult task instead of her internal smoldering desire. She had to push a chair up to the counter to be able to reach a glass from the cupboard, and then got her hands and the outside of said glass all wet while trying to fill it without being able to see very well.
But at least once that was done and she'd dried off, she was able to return victorious. She stepped close to Laine and turned around to present his water.
"Oh, thanks," he said, taking the glass from her.
"You're welcome."
Catria stood there, intending only to let her brother get another few seconds to check out her butt. She squeaked in surprise as he instead grabbed her ass without warning.
She looked over her shoulder at Laine. He was gazing appreciatively at her nearly-bare bottom while also fondling it with one hand. She bit her lip and tried not to lose her balance. She'd become a little unsteady with the sudden, unexpected attention.
"Yup," Laine said. "Weapons-grade alright."
Catria blushed. "Thanks."
Laine pulled his hand away, then patted his lap. "Here. Come lie back down."
"Ok."
She tried to retake her former position, but Laine had a bit of a different idea. He maneuvered her even further across his thighs than before. She surrendered easily to being adjusted like a pillow.
In all the excitement, such as it was, Catria hadn't realized that Laine had put his game away until he started a movie playing. She was about to protest that he really didn't need to do that, but his hand landed on the small of her back, and she thought better of arguing the point.
He wanted to play with her some more. Thrills ran up her spine at the realization. He wouldn't say so aloud, but between moving her closer and freeing his hands and attention, that had to be his intent.
Catria rolled just a little to get comfortable, subtly sticking her butt out a bit more in the process, just in case. Once settled she went still and waited.
Soon enough, Laine got busy feeling her up again. He started out pretty slow, at first just rubbing her lower back. His fingers eventually slipped under her top to rub her bare skin.
Her camisole got pushed higher and higher up her back as her brother explored the smooth flesh between her ass and shoulder blades. It was nice, in a comforting and familial kind of way. It would be the perfect way to be lulled to sleep. Catria couldn't imagine a more secure or loved sensation to drift off to.
The only problem was it wasn't nearly naughty enough. She was too damn horny to put up with mere back rubs for too long. She knew Laine was aroused too, thanks to being laid across his lap. There was no way to hide an erection when it was poking straight into her tummy.
Catria rocked her hips, but there was nothing to grind against. She was unable to help herself out and was entirely reliant on Laine, who seemed in no hurry at all.
"Stop squirming," Laine said.
"I'm not."
"You are. You're being all wiggly."
"Well you... you're...."
"I'm what?"
"You're being a tease."
"I'm the tease?" Laine plucked the back of Catria's panties and let them snap gently back against her butt. "You're gonna try and tell me you didn't wear these specifically to make me look?"
"Um...."
"Yeah, that's what I thought."
Laine gave her ass a quick, sharp smack. She yelped, but then lifted her hips in case there might be a second spank coming. There wasn't.
At least he didn't totally ignore her needs. His hand stayed on her bum, rubbing its small circles there instead of her back. That was a definite improvement.
Catria was pretty sure her panties were getting damp. She couldn't check to make sure. Eventually Laine might get there and find out for her. Maybe. Could she let him do that? Feeling her up was one thing, but her pussy....
Oh who was she kidding. She'd totally let him.
Unfortunately for her pervy fantasies, Maggie arrived home and spoiled any chance of Laine getting too carried away with fondling her.
Catria expected Laine to make her sit up and act like they were being good... ish. However, he didn't make her go anywhere, and she was perfectly fine with remaining sprawled across his lap, so she was still there when Maggie joined them.
"Hey, guys," Maggie said.
"Hey," Laine and Catria chorused back.
"Aren't you cozy," Maggie said. She lifted Catria's legs, making her little sister giggle as she was rearranged, then settled in with them.
"Yeah, we're pretty snug," Laine agreed.
Catria bit her lip and waited for some comment about her underwear, or being on Laine's lap, or... something. She knew it was coming. It couldn't be that bad if Maggie hadn't reacted right away, but it was still going to be something.
Sure enough....
"Was someone being a naughty little sister?" Maggie asked.
Catria flushed and tried to think of a good answer.
"Yeah, she kinda was," Laine answered instead. "I got her mostly under control."
"Uh huh. I notice you didn't make her go change."
"How well do you think that would have worked?"
Catria listened to the back and forth. They were acting like she wasn't even there, or indeed listening to every word they said.
Probably they were just teasing her. Maggie wasn't overtly upset, and Laine had already accepted and enjoyed her choice of underwear.
Catria stiffened as her butt was grabbed. It wasn't even Laine this time. The fingers were noticeably more feminine than his. Maggie was getting a feel? That was a bit of a curve ball. Not a bad one though.
"Isn't that right, Cat?" Maggie said.
Catria realized belatedly that she'd missed some of the back and forth between her siblings. She was lacking context for the question she'd been asked.
"Uh... what?" she said.
"I said you're not going to be this bad all the time, right?"
"Oh. Uh... no?"
"Good answer. I hate to think what you'd do to your poor brother showing off your butt like that every day."
A final pinch, then Maggie left Catria's bottom alone again.
'Poor brother' indeed. His cock was still jabbing Catria's tummy. She smiled to herself. That could just be between her and Laine. Maggie didn't need to know just how bad they were being.
****
Later on that night, Maggie was getting ready for bed. Her mind had been occupied with Laine and Cat ever since she got home. Finding her siblings in such a compromising position right in the middle of the living room was gnawing at her.
She couldn't help wondering if there was more going on than she thought there was. There was obviously some sexual tension happening. The whole house had been filled with it ever since Cat had discovered her predilection for handcuffs. It had only been increasing as her sister had become more confident and experimental.
The problem was that Cat seemed to have figured out how much control she could exert over her brother. Laine was practically helpless when she wanted his attention, which was interesting given that he wasn't the one in handcuffs.
Maggie was worried about one of them going too far or getting hurt, though she wasn't sure which of her siblings she should be more concerned for. She also wasn't certain where 'too far' was. Light bondage, showing off, and even some questionable touching had become normal for them, and that wasn't supposed to be the case for siblings. There really weren't any societally approved guideline for their situation.
There was also the issue that Maggie didn't want to be 'the mom.' She accepted some maternal responsibilities, and wanted her brother and sister to stay safe and happy, but she was nowhere near ready for actual parenthood yet, let alone starting with two grown-ass, technical adults.
Maggie stopped at Laine's room on her way back from brushing her teeth. She thought maybe talking with him would help. He was the second most parental of the three of them, after all.
She knocked on his door, then opened it. Laine was just pulling off his shirt in preparation for bed.
"You know," said Laine, "you and Cat really need start waiting a second after knocking. Kinda defeats the purpose otherwise."
"You gonna act shy now all of a sudden?"
"No. But I might start barging in on you two, see how you like it." Laine paused. "Actually, maybe just you. Cat probably wouldn't even mind."
"Ha, yeah. She probably wouldn't." Maggie smiled at the mental image of their little sister hanging out naked in her room, hoping someone would 'accidentally' walk in on her. Her smile faded as she realized it wasn't that far off reality. "Actually, I kinda wanted to talk about Cat."
"Oh. Good talk or bad talk?"
"Well... not necessarily either."
"I see."
Maggie glanced back toward the hall. "Maybe I should shut the door."
"I wouldn't worry about it. I just tucked her into bed."
"Ah. Right."
Laine frowned. "Are you annoyed about that?"
"No."
"Really? 'Cause your tone kinda says you are."
Maggie scratched her ear. "Well, maybe I am. A little. I don't know exactly what I'm feeling."
"Maybe it was a good idea to talk then."
Laine gestured to his bed. He and Maggie sat down next to each other. She gave him a crooked smile.
"You tell me I'm gonna be a good mom," she said softly. "But you've kinda got the dad thing down."
"What, just because I tuck Cat in sometimes? That's only 'cause of the cuffs. Gotta get her in bed, and make sure she hits the bathroom first and... oh goddammit, I am doing dad stuff."
"Yeah. You are."
"Well shit." Laine sighed. "Well at least she can still look after herself most of the time."
"Until she can con you into doing more for her."
"You say that, but honestly I think she's perfectly happy to do stuff if she gets asked the right way."
"You mean bribing her with cuff time?"
"That's one way. Or just, like, tell her. All dominant-like. She responds to that kind of thing."
"True. Too bad we're both pretty bad at being 'all dominant-like.'"
"Ha, yeah."
Maggie contemplated for a moment. "I'm not sure if I'm worried," she said, "or, like, kinda jealous, maybe."
"Jealous?"
"Yeah. You can Cat got a thing kinda going on. And I don't really fully understand what it is. And I don't know if I should be worried what it's doing to you, or envious because I'm not part of it."
Laine scratched his knee, then fiddled with the leg of his boxers. "You're probably right to worry a little," he finally said. "I know I do. But if you want to be more included in Cat's whole subby bondage thing... I mean, that's all up to you. She's been latching on to me so much lately just 'cause she figured out what she does to me. It's an attention thing as much as anything else."
"I don't think that's true. She loves her big bro, y'know?"
"Yeah, but she loves her big sis too. If you started showing more interest...." Laine shrugged. "I mean, I'm just guessing though."
"So, what, stare at her like you do when you think neither of us is watching?"
"Hey, now."
"Feel her up more?"
"I know you think you're being funny, but yeah. Stuff like that. Or start putting her to bed sometimes. Or just put her cuffs on during the day when she's not expecting it. Or whatever."
Maggie snorted. "Bondage bonding time, huh?"
"Basically, yeah."
She stood. "Alright. I'll have to think about it. Try and figure some stuff out."
"Ok. Don't be afraid to come talk some more if you need to. We're in this together, you know."
"We really are, aren't we." Maggie turned back for a second and smiled wanly. "Thanks for... you know. Being you."
"It's what I'm best at."
"Night, Laine."
"Night, Mags."
She left the room and closed the door behind her. She had some more things to think about, but her head felt a little less chaotic, so that was something.
Maggie decided to check on Cat before bed. Maybe her sister would still be awake and they could chat a bit. It would be nice to get a sense of how she was feeling these days.
That didn't really happen, however. Maggie opened the door to Cat's room and instead of finding her curled up under her covers, Cat was wide awake and kneeling on her bed. She was, in fact, straddling a pillow. A humming pillow.
Cat's eyes were wide, her face was slowly going bright red. She didn't say anything, but she didn't have to. Maggie was a little slow on the uptake, but she figured out what she was seeing.
"Laine might be right about the whole knocking thing," Maggie said aloud.
Cat remained silent and furiously blushing.
"I'll, uh, see you in the morning," Maggie said. "Maybe. Uh... yeah."
She closed the door behind her and leaned against it for a moment. Her own face felt about as warm as Cat's had looked.
Riding a vibrator though, that was pretty clever. Maggie had given no thought to masturbating without one's hands free, but in retrospect it would have been naive to assume that Cat just went without every night. Horny little thing that she was, she'd never get any sleep.
Hopefully they weren't both too embarrassed to look at each other in the morning. Hopefully.
****
Catria had been caught at her nightly masturbating. She could have pretended that it was unexpected, but honestly it was bound to happen sooner or later. If anything, it was overdue.
She'd felt a sense of embarrassment not unlike when she'd pissed herself in front of Laine. This time wasn't quite as humiliating, but still did lovely, tingly things to her insides.
She'd stared at her big sister while her vibrator whirred away under her pussy. Maggie had seen exactly what was going on and, if anything, might have been the more embarrassed of the two of them.
Catria's orgasm afterward had been one of her bigger ones. Certainly the nicest she'd had in the past week or so. Lots of pent up arousal from teasing and getting teased by her brother, then some added stimulus from her sister all melded nicely to get her off explosively.
Of course she'd have to make sure Maggie was ok in the morning. It was getting to be such a lot of work keeping her siblings' emotions in check.
She woke up the next morning to Laine sitting gently next to her on her bed. She smiled sleepily at him, then rolled over to have her wrists released.
"You really should put your sex toys away when you're done with them at night," Laine said.
Catria giggled. "Toy. Singular. It's the only one. And why should I care? Everyone's seen it at this point."
"I dunno. A sense of propriety." Laine put a hand on her lower back before she could retort. "Yes, I know how silly that sounded once I said it."
"Good. 'Cause we don't have much for propriety these days."
"No. Indeed we don't."
As emphasis to his agreement, Laine grabbed her ass. She was still wearing her tiny little panties, and he mostly got a handful of pure sister-butt.
"Ooh," Catria cooed.
She could get used to waking up to this.
Laine fondled her a little more, then gave her bottom a light smack. "Hey, Cat?"
"Yeah?"
"Go ask Mags to unlock you this morning, would you?"
Catria frowned. She wasn't averse to the request, but it didn't make much sense to her. "Why?"
"'Cause I think your sister would appreciate it."
"Really? I'm not sure. Last night there was kinda--"
"Cat?"
"Yeah?"
"Trust me on this one."
Laine gave her bum another smack, then left.
Well, she couldn't argue with that. Plus she needed to talk with Maggie anyway. Two birds, one stone. All that nonsense.
After lazing around another few minutes, Catria finally rolled out of bed. She grabbed her key and padded down the hall to her sister's room.
Her ass cheek still had just the faintest tingle from where Laine's hand had landed. She wondered if there was a visible mark, even just a warm little red spot. She peeked over her shoulder, but the angle was terrible and her arm was in the way. Oh well.
Catria entered Maggie's room quietly. Her sister was still sleeping, and she didn't really want to wake her. Then again, it probably wasn't a great idea to just stand there staring until she woke up either.
"Mags? Mags. Are you awake?"
Catria crept closer and called out again in the soft voice of someone trying paradoxically to wake someone else up without disturbing them.
Maggie cracked an eye open, then groaned. "What is it?"
"Um... Laine said to come get you to unlock me this morning."Maggie snorted. "He did, did he?"
"Yeah."
"You probably weren't supposed to tell me that part."
"Oh. Yeah. Probably not." Catria shifted her weight, bouncing from one foot to the other. "So, uh, will you though?"
"Ugh. In a minute maybe. M'not ready to get up yet."
"Ok."
Catria shifted feet again while looking around the room. There was nothing much to catch her eye other than Maggie, and she was trying really hard not to stare.
"Are you just gonna stand there?" Maggie asked.
"You said a minute. What else am I gonna do?"
"That was... forget it." Maggie pulled back the covers. "You wanna come lie down?"
Catria stepped forward eagerly, but hesitated before actually getting into bed. "Does that mean you're not upset about what happened last night?"
Maggie gave Catria a crooked, sleepy look. "Upset was never quite the right word. But no, I'm not."
"Ok. Good."
Catria dropped her key on Maggie's dresser, then rolled into bed next to her sister and let the covers be draped back over her. It was snuggly and warm underneath from Maggie's body heat.
"I didn't mean to walk in on you like that," Maggie said.
"It's ok."
"It bothered me a little at first, for a few different reasons, but honestly, it wasn't like I didn't know you... did stuff...."
"Masturbated?"
"Yeah. I just never thought much about it." Maggie shrugged. "But after thinking about it and getting some sleep... I guess I really don't have much emotional investment in when or how you play with yourself."
Catria decided not to mention that it was kind of exciting talking about her masturbation habits. She'd never really done it before.
"Where'd you get it anyway?" Maggie asked.
"My vibrator?"
"Yeah."
"There's a shop about a twenty minute walk from school. Me and a friend went one time, kinda like daring each other. She couldn't believe I actually bought something."
"Huh. Braver than me, then. My first one came from an online store."
Catria grinned at the naughty secrets being shared. She supposed it was just girl talk, in some ways, and not really something she should be enjoying so much. But it was new to her.
Her friend and her had only visited that shop together once, and they'd never really discussed anything about it except to giggle maniacally about it a couple times. That felt like so long ago, like she'd grown up since then. Which she had, technically.
"Does that mean you have a lot?" Catria asked. "Like a whole box full?"
Maggie grinned, then chuckled. "Don't get too excited. I have a couple. And I'm not ready to go into detail about my toys with you."
"Aw."
"Maybe someday."
"Promise?"
"No. Just maybe is all."
"'K."
Maggie pushed some of Catria's unruly hair back from her face. Her fingers were soft and gentle. Catria had really been appreciating the differences between her siblings' touches lately.
"Roll over," Maggie said.
"On my back?"
"No. Do a one eighty."
Catria was confused until she did what she was told and felt Maggie snuggling up behind her. It all made sense then, though she was kind of surprised her sister wanted to spoon.
Maggie pressed right up against her, encircling her waist with one arm. Catria felt her warm breath on her neck. It was nice.
"I just want to lie here a while," Maggie said.
"Ok," Catria said faintly. She hoped her heart wasn't beating too hard and giving her away. She hadn't expected anything like this, but now that it was happening she didn't want to ruin it.
Maggie's hand pressed warm and soft against Catria's tummy. It circled and flexed, and slowly crept upward.
Catria held her breath as her sister came closer and closer to her breasts. She'd been so excited when Laine had casually started playing with her tits. It seemed improbable that Maggie would do the same, but Catria was full of hopeful anticipation anyway.
"You know what I've been wondering about?" Maggie asked.
"Um... no, not really."
"Sexual attraction."
"Oh." Catria wondered if she was supposed to say something meaningful in response. She decided just to wait and see.
"The thing is," Maggie continued, "that we all basically limit ourselves in who we look at, and think about, and lust after."
Catria inhaled sharply as a finger brushed the underside of her tits, then it was gone again.
"Like, Laine never used to check either of us out. Not really. He'd look every now and then, which was only fair. We didn't try overly hard to dress properly around the house when it was just the three of us."
Maggie's thumb flicked across one of Catria's nipples, provoking a small, muffled squeak.
"But now he stares at you practically all the time," Maggie said. "And I can't help wondering whether you've changed, or he has, or most likely some combination of both."
She cupped one of Catria's boobs in her hand. She rolled the soft flesh gently in her palm.
"Is it because you've become sexier?" Maggie whispered. "Or is it just that you've become more acceptable to him? Is your sexuality winning over familial boundaries?"
Catria muffled a moan and decided not to point out that she seemed to be winning over more than just her brother.
"Perhaps more importantly," Maggie said, "is what am I supposed to feel about all of this?"
Catria couldn't help herself. "Right now... seems like my tits."
Maggie giggled softly and gave her sister a light pinch on the nipple. "Yes, that's true." She gave one last squeeze, then put her hand back on Catria's tummy where it was safer. "I wanted to see what you'd do. And, admittedly, how I'd feel about it?"
Catria swallowed. "And?"
"It was nice. You have lovely little boobies. And you didn't seem to mind me playing with them, which I wasn't totally sure about."
"How could I possibly stop you?"
"Don't play innocent. You didn't say a damn thing. And don't think I couldn't feel the way your heart's pounding."
Oh. So it was obvious after all. Live and learn.
"Is it bad that I didn't tell you to stop?" Catria asked.
"Depends. Did you want me to?"
Catria hesitated, then shook her head. "No."
"Then it's fine. But Cat? If you ever want me or Laine to stop or... or whatever... you have to tell us, ok? I don't think either of us have a good sense of your boundaries these days."
"Ok."
"Ok." Maggie patted Catria's tummy. "Alright, let's get this day started. Up ya get."
Catria reluctantly got out of bed, followed closely by her sister. She held still while she was uncuffed.
"Go on then," Maggie said. "Get ready for school."
Catria nodded and started to leave. She hesitated, then turned back and hugged Maggie. "Thanks for putting up with me."
"You silly girl," Maggie whispered back. "You're my sister. I love you."
"Yeah. Me too."
Catria disengaged and left for real.
****
Laine was welcomed home by the divine scent of baking cookies that evening. He couldn't remember the last time he'd eaten a cookie that didn't come out of a package. Maggie must have been in a pretty damn good mood, he thought.
Even more unusually, however, he'd assumed the wrong sister. Cat was the one busy in the kitchen. Maggie was nowhere to be found. Huh.
"Well well," Laine said.
"Oh, hey," Cat said, feigning nonchalance.
Despite her apparent lack of enthusiasm for his arrival, Laine was pretty sure it was all planned. Either that or Cat had taken her pants off just for fun. Which actually wasn't entirely out of the question.
She was wearing another pair of panties that did precious little cover her bottom. Her hips swung back and forth slightly as though swaying to inaudible music.
"Look at you being a little baker," Laine said, deliberately not mentioning anything related to how good her ass looked.
Cat shrugged. "I'm just scooping out some store-bought dough onto pans. Pretty simple stuff."
"Still, though."
Laine walked up behind her and wrapped his arms around her waist. She giggled and leaned back into him. She was so soft. The smell of baking cookies surrounded them and combined with her own subtler scent to form an intoxicating mixture.
"I just wanted to do something nice," Cat said softly. "You and Mags have been so good to me. Especially this morning. You were right about going to see her."
"Is that so? What exactly happened?"
"She didn't tell you?"
"No."
"Then I guess it's girl stuff. Secret."
"That's not fair."
"It's not, is it." Cat turned toward the over as a timer went off. "That's the first pan. I gotta get them."
She slipped out of Laine's arms and handled the changing of the cookie sheets, only burning herself a little on the hot pan from the oven. He meandered over to the fresh cookies while she ran her finger under cold water.
"You should let them cool a bit," Cat warned.
"Eating them while they're still too hot is half the fun," Laine countered.
He changed his opinion almost immediately when his tongue encountered a molten chocolate chip.
"Told ya," Cat said.
"Stupid chocolate being so hot."
"Yeah, that's definitely the problem."
"Ok, ok. So maybe I should give them a minute."
Cat nodded, then went back to examining her finger.
"Does it hurt bad?" Laine asked.
"Nah. Just a little burned spot. It'll be fine."
"Cool." Laine eyed the pan of cooling cookies. "Hey, wanna load these all up on a plate and go pick something to watch?"
"What, the whole sheet?"
"Why not?"
"I... don't know." Cat grinned. "Yeah, sure. Let's make ourselves sick on baked goods."
"That's the spirit."
For the next little while, that was exactly what they did. Laine and Cat cuddled on the couch eating cookies, taking turns picking something to watch, and getting a bit handsy from time to time.
Cat cracked first and let out a long groan. "Ugh, I don't know why I thought this was a good idea. My tummy is not happy with me."
"Hm, yeah. Mine either, actually." Laine rubbed his stomach. "Maybe should have stopped sooner."
"No kidding."
The siblings, having eaten too many delicious treats, slumped in their seats and occasionally rubbed their bellies as though it would help. Laine wasn't in quite as bad shape as Cat appeared to be, and he couldn't help noticing the way her tits moved when she moved her hand beneath them. She wasn't really paying him any attention, and his sidelong glances turned into zoned-out staring.
Laine finally grabbed Cat and pulled across his lap on her back. She giggled and happily let herself be thrown around.
"Let me do that for you," Laine said.
He spread his hand out over her tummy and rubbed in gentle circles.
"Mmm, ok," Cat said with contented, half-lidded eyes.
Laine knew he was getting dangerously obsessed with touching his sister. Not even necessarily in inappropriate ways. Just... feeling her. Cuddling with her.
Admittedly, the naughty stuff was nice too.
Cat lifted her burned finger up to her face and examined it. She didn't seem to be in any immediate distress about it, but was probably just checking.
"Your finger doing any better?" Laine asked.
"Kinda. Just stings a bit." Cat grinned mischievously and held her hand up toward him. "You could kiss it better."
Laine stared at the proffered finger for a moment, then leaned forward and brushed his lips against the reddish spot on it.
The expression on Cat's face changed. Her hand stayed in the air, then slowly pressed back to Laine's mouth.
He let her soft finger trace his bottom lip, then opened his mouth and let her fingertip inside. He sucked gently on her digit and caressed it with his tongue.
Cat stared wide-eyed up at him and thrust her finger in and out in small, rhythmic motions.
Laine wasn't quite sure what was happening, but it was turning him on. His cock was poking into Cat's back, trapped beneath her kind of painfully.
He switched from massaging her tummy to rubbing her tits. She moaned and pushed her finger even deeper into his mouth. She wiggled and squirmed in his lap, inadvertently grinding his erection.
Order devolved even further from there. All sense of decorum was abandoned between the two horny siblings.
Cat lifted Laine's shirt until he got the hint and removed it entirely. She bit her lip and rubbed his bare chest, then returned her hand to his mouth. She stuck two fingers inside this time. Once they were covered in his saliva, she stuck her hand down her panties and toyed with herself.
Laine watched his wanton little sister finger her pussy under her panties. His hand stayed busy on her chest. He eventually got bold enough to push her shirt up over her breasts and fondle them directly.
Her eyes glazed over from sheer lust. She thrust her chest up to meet her brother's inappropriate caresses, and her fingers only danced all the faster on her pussy now that she was practically topless.
Laine's gaze bounced between Cat's panties, her boobs, and the cute, overwhelmed expression on her face. She was hot and out of control, and dragging him right along with her.
He watched his sister cum right in front of him, right in his lap. Her lithe body tensed and trembled, and she made such adorable mewling noises.
"You're so beautiful," Laine said.
Cat looked up at him, her face all flushed and smiling shyly. "Thanks. I mighta got a little carried away there...."
"You did."
"Pretty bad, huh?"
"Yeah." Laine traced a line from her belly button up between her breasts. "You're kind of a bad little girl."
Cat had been starting to calm down, her breathing gradually normalizing. Her eyes lit back up. "A bad little girl?"
"That's what I said."
"So I guess I... shouldn't pull my shirt back down? Since I'm so bad?"
"You can leave it," Laine agreed. He booped one of her nipples.
"That must make you kind of a bad boy, then," Cat said.
"Because I'm not making you cover yourself?"
"That. Also you've been poking my back pretty hard."
"That's kinda just what you do to me."
"Mmhm."
Cat sat up, relieving some of the uncomfortable pressure on Laine's erection. Her perky tits were even closer to his face, though not close enough that he was tempted to do something brazen.
She settled in next to him, tits still proudly displayed, panties noticeably damp. Her hand went to his lap, at first settling tentatively over the bulge in his pants. She glanced sidelong at him, and seemed to gain confidence from his reaction.
Laine was probably letting his sister get away with more than he should. But then, that bridge had already been crossed. She'd masturbated right in his lap. It wasn't really a big stretch from there.
Cat was getting more forceful, really grinding her palm against his cock. It was nice, but it wasn't enough. If they were doing this, if it was going to happen, they needed to commit.
"I think my pants need to come off," Laine said.
Cat nodded absently. "Good idea."
She kept rubbing his cock.
"That means you need to let me stand up," Laine added.
"Oh. Right."
Cat jerked her hand away from her brother's hard cock and bounced off the couch. A bemused Laine followed a bit more slowly. He started to undo his pants, but she was faster.
Cat knelt down in front of him and tore at his jeans like it was a race. It was so much nicer once she got his pants pulled down his legs and his cock had more space to breathe. It was still contained in his boxers, but they didn't restrain it quite so tightly.
"You're awfully eager," Laine said.
That slowed Cat down a little. She had his pants off, and she was still kneeling in front of him. She was a picture of sexy innocence with her perky tits still out and a slightly hesitant look on her face.
"Is that bad?" she asked.
"No. Just... you know. Interesting."
She squirmed indecisively. "You're making it sound weird."
"Not weird. Not exactly."
Cat gazed up at her brother, a slight pout in her expression. "I wanna see it," she said. "I know you get hard around me, and I like that, but I never get to see. Or play."
"That's supposed to be how it works with siblings, you know."
"Yeah, but... it's different with us. And usually I have cuffs on when stuff happens, so I just wanna play a little." Cat made big puppy eyes. "Please?"
"Hey, don't look at me like that. I never told you to stop."
"No. I guess you didn't."
In fact, Laine had been a little worried that he was going to have to be responsible thanks to their conversation. He was just as eager as his sister, if not more so thanks to his teased and ignored erection.
He was horny, dammit. And it was all Cat's fault. Her and her soft titties and pouty eyes and wanton attitude and... everything really.
Cat's eyes were bright and excited as she pulled down Laine's boxers. Her mouth went adorably round and appreciative as his cock sprang free, nearly catching her across the nose from her proximity.
"Oh wow...."
Laine flushed. He wasn't as used to being examined as she was. It was nice, but also a little uncomfortable.
Fortunately, Cat seemed fantastically happy with the toy she'd found in his underwear. She ran her fingertips along his shaft, touching it oh-so-delicately while her warm breath caressed it from the front.
She really was fascinated. Laine's discomfort gave way to a dull pride as his little sister fondled and stroked his cock. Now that she'd started, he had an insanely strong need for her to continue. Not that she showed any sign of wanting to stop.
Cat played with his cock using both hands and a variety of grips and pressures. Her experimentation felt amazing, but was even better once she finally tried out her mouth.
Laine let out a low moan as her tongue flicked across the tip of his straining erection. She smiled at the response and licked again. She danced her nimble little tongue all around his shaft, over the head, the underside, all the way to the base. Her eyes met his frequently as she looked up for approval.
"Goddamn you're beautiful," Laine whispered. He put his hand on Cat's cheek and she leaned into it, nuzzling at his palm for a moment before returning to her exploratory licking mission. "The crazy thing is I never would have realized just how amazingly sexy you are if you hadn't become so obsessed with those handcuffs."
"No," she agreed. "And I probably wouldn't have wanted you to." She gave him a cheshire grin. "But it turns out I love you perving on me."
Still smiling wickedly, Cat clasped her hands behind her back, parted her lips, and leaned forward. She engulfed almost half her brother's cock in one go.
Laine's legs went weak at the sight of his little sister giving him a hands-free blowjob, tits still out, puppy eyes being used to full effect. She valiantly tried to get more and more of his cock in her mouth, though was limited by inexperience and her refusal to use her hands to help.
Laine was pretty sure she was simulating having her wrists cuffed, though he wasn't totally sure if that was for his benefit or hers. Probably hers. She liked those things more than he ever would. They did things to her, things he didn't fully understand.
"Good girl," he said on impulse. He stroked her hair. "Good little sister."
Cat's cheeks reddened and she bobbed her head faster.
He stepped back and sat down on the couch. His cock popped free of her mouth with a small explosion of saliva.
Cat frowned in annoyance that her penis had been taken away. She crawled forward on her knees and bent down to his lap to get back to work. She had to use a hand to steady herself, but she made a good effort of working without it as much as possible.
Laine ran his fingers through her hair, occasionally murmuring some small compliment or encouragement. She was dedicated and hardly so much as stopped for air.
Cat was so single-minded, in fact, that she seemingly forgot what she was working toward. Despite Laine's last-second warning, she still coughed in surprise and hurriedly pulled her mouth off of his cock once cum began shooting out of it.
Some semen got in her mouth, but most landed on her face, and some on his own lap. She knelt there panting for a moment.
"Oops," she said quietly.
"That was so good," Laine said, leaning back heavily.
"I kinda forgot about the end bit."
"Yeah, I figured."
"I wanted to get it in my mouth, but--"
"Cat?"
"Yeah?"
"That was amazing."
She flashed her familiar shade of red in a mix of pride and embarrassment. "Well I mean, I could do better...."
"With practice, sure." Laine pulled her up into his lap. "Don't worry about that right now."
"Ok," she said faintly.
Laine pulled her in for a soft, loving kiss. She melted against him.
"We should probably clean up," he said.
"Mmhm," came her reply, muffled against his chest.
"You kinda have cum all over your face. Or I guess a lot of it's on my shirt now."
"S'ry."
Laine waited. Cat didn't move.
"Or we could sit her a bit longer," he said.
She nodded. "'K."
"Yeah. Thought so."
Laine held his sister, cradling her lovingly in his lap. She certainly didn't seem to want to go anywhere at the moment, and the longer he held her, the more he concurred. Thoughts of cleaning up became distant secondaries to how nice it was having her all warm and snuggly pressed against him.
Her shirt was still hitched up over her breasts. One of his hands found the small of her back and he spread his fingers over her irresistibly smooth skin. He rubbed her back slowly and soothingly.
Cat's hips began to rock gently in response. The longer she was held and caressed, the more noticeable her movements became.
Laine moved his hand down a bit and patted his sister's tight, barely covered ass. Then he gave up on subtlety and grabbed her butt with both hands.
She moaned into his chest and shifted around so she could grind on his thigh instead of empty air. She lifted her head and opened her bright, lustful eyes. Streaks of drying cum still marred her face. She looked sluttier than ever before, but no less beautiful.
Laine shifted a hand to the front of his sister's panties. She happily ground against his palm instead of his leg. He pressed harder, providing a more firm contact for her.
Cat's mouth fell open in a soft pant. Her pussy was in constant motion against her brother's hand. She was a desperate, horny little thing.
Laine let her rock for a while, then eventually slipped his fingers into her panties to feel her pussy directly. She only became wilder as he touched and fingered her. Searching for her clit was tricky because he couldn't see and it was a constantly moving target, but he soon realized she'd be able to line it up better than he would.
She came on his fingers in a last, brief flurry of wiggling, moaning, and burying her face in his shoulder. Her hips gradually slowed, then stopped. It was longer still before she pulled her head back far enough to look at him.
"I mighta got a li'l carried away there," she croaked.
Laine smiled. "I loved it."
He kissed her tenderly, little more than a brush of his lips on hers, but the way she beamed afterward made it seem like much more than that.
"Seriously though," he said. "You really need to get cleaned up."
"Aww."
Laine rolled his eyes, having already suspected he'd have to bribe his reluctant sister. "And then once you've showered and changed, we can put your cuffs on."
Cat perked up. "Oh. Ok then."
And off she went, humming cheerfully to herself.
Laine watched her butt sway until she left the room. He looked down at himself and the disorder of the couch in general. He didn't feel like tidying, but he should do a little, he supposed.
Maybe later.
****
Catria couldn't believe what had just happened. She got herself off again in the shower just thinking about it.
She stood there, all warm, wet, and naked, showerhead pressed to her clit. She could still taste Laine's cock on her tongue. He'd actually let her suck him off, then exploded all over her. The memory made her shiver in naughty delight.
She desperately wanted to try it again, except with her handcuffs on. At the time, she hadn't dared break the magic to rush off and get them. There had been a chance Laine would change his mind and decide they probably shouldn't fool around quite so much. He'd been as horny as she was, so maybe the chance wasn't all that high, but he did sometimes feel the need to be 'responsible.'
After her shower masturbation and subsequent squeaky cleaning, Catria dried off and headed to her room to get dressed. She padded naked through the hall, and only after she reached her room realized what she'd done. It used to be that she would have been thrilled and scared to do something so daring. Now it almost didn't even register.
She saw no reason to dress too modestly. She was really getting to enjoy flaunting herself around Laine, and maybe around Maggie too in a slightly different kind of way.
Panties and cute little tops were all she needed around the house anyway. They covered her enough that neither of her siblings chastised her about her outfits, but also showed enough skin to be exciting. Especially when she wore her newly purchased tiny panties and low-cut camisoles.
Laine and Maggie both knew exactly what she was doing. She knew that. But they had yet to stop her, and the rate her and Laine were going, he certainly wasn't going to be a problem. Maggie still might be. Maybe.
Catria pondered about her big sister as she slipped into her top and pulled her panties tight up around her butt. Laine was pretty simple these days. They were both horny little things, and they wanted to tease and mess around, so they did. It was only going to get more interesting, she assumed.
But Maggie... well, she wasn't quite sure what she wanted from her, nor vice versa. It wasn't quite as exciting showing off for another girl, even her sister. And certainly she never caught Maggie staring the way Laine would, or trying to hide a bulge in her pants, or generally just being a boy instead of a sibling. Because she wasn't.
Although, Catria admitted, she definitely loved Maggie, and she liked when her big sister got a little naughty. And being bad around both her siblings was fun too, since then there was the whole three way dynamic going on, and so much more uncertainty.
Catria missed the uncertainty she used to feel. Those first days of figuring out what a little handcuff slut she was were treasured memories. There was plenty of fun still to be had, but nothing that made her tummy flip quite the same.
She was still musing as she scanned her room for her handcuffs. It was just a casual look around at first, but gradually escalated until she was digging through her clothes and peering under the bed. She couldn't find them anywhere.
Luckily she recalled that she'd left them in Maggie's room that morning before she got too frantic. She hurried down the hall to her sister's room and burst in, eyes already whirling as the door opened.
What Catria hadn't counted on was that Maggie was currently occupying the room and was, in fact, in the process of changing. She must have just come home.
The sisters stared at each other for a moment. Catria was torn between ducking back out, and dashing in just long enough to grab her cuffs. She settled for the classic indecisive move of standing perfectly still and waiting for a brilliant moment of clarity that would never come.
Maggie was first to move. She was completely topless, having presumably taken for granted that she'd be all alone in her room for a few minutes. She pulled on her change of shirt and covered her breasts.
"Yep," she said. "Laine's definitely onto something with the whole knocking thing."
Ice successfully broken, Catria stirred as well. "Um... I kinda just came for my cuffs."
"Did you, indeed?"
"Yeah. Laine said he'd lock me up early."
"Mmhm." Maggie gave her a piercing stare. "You two must have been having fun."
"Well, you know, kinda."
"Uh huh." Maggie sighed. "Alright, come here."
Catria obediently walked over and turned around. There was a satisfying double click, then she was all handcuffed up the way she loved.
"Thanks, Mags," she said.
"You're welcome. Knock next time, would you?"
"Sure. You have nice tits though."
"Yes, I know. That doesn't mean you get to walk in and stare at them whenever you want."
"Or maybe--"
"Cat, get the hell out of here before I throw something."
"'K."
Catria returned to her brother who was looking presentable again. She bounced down on the couch next to him and snuggled right up.
"So Maggie's back," she said.
"Yeah, I know. She cuff you?"
"Yup. I accidentally saw her tits. They were nice."
Laine gave her a funny look. "I imagine they would be. Why are you telling me?"
Catria shrugged. "I dunno. Just felt like it." She was quiet a moment, lost in thought. Then, "Do you think hers are nicer than mine?"
He sighed. "I was afraid that might be where this was going."
"You were?"
"It was a distinct possibility, yes. You just had that kind of look on your face."
"Really? Huh." Catria considered that. "Maybe I did." She looked down at her chest. "I guess it's just that now that I've seen Mags' boobies, I kinda wish mine looked like hers."
"Well maybe you should talk to her then. Get some booby growing tips."
"So you do think hers are better?"
"Cat, I swear to god. I am not doing this." Laine grabbed one of her tits and gave her nipple a sharp pinch. "I love your boobs, and just because Maggie's are a little bigger--"
"And nicer."
"Bigger," Laine insisted. "Bigger is all they are. You don't need to worry about it."
"Maybe it's just because you haven't seen her topless," Catria mused. "Maybe we should--"
"Please don't finish that sentence."
"No, please," said a voice from across the room. "What should we do about my boobies?"
Catria and Laine both looked over at Maggie who was leaning casually against the doorway. The looks on their faces were almost identically guilty.
Catria, however, had gained much experience with being embarrassed around her siblings. In some cases, it only made her stronger. Despite her red face and nervous tummy, she barely faltered.
"I hope mine keep growing a little," she said. "That's all."
"Just because you saw mine for, like, half a second?" Maggie asked.
"It was several seconds at least," Catria said. "I mean, we kinda just stood there for a bit. I can't quite get them out of my head now." She gave her sister a hopeful look. "Do you think I could feel them?"
Maggie walked closer, her eyebrow arched sardonically. "How exactly would you do that with your handcuffs on?"
"Oh yeah. Well maybe--"
"Guess that are some downsides, huh?" Maggie sat opposite Laine on Catria's other side. She casually reached out and fondled her little sister's breast. "Whereas I can get any kind of feel I want."
"I guess that's true," Catria said faintly. She bit her lip and tried not to look too much like she was enjoying it.
After a moment, Laine resumed groping her other breast where he'd left off. Catria had both her brother and sister feeling her up at the same time.
There were two of them against defenseless little her. She couldn't have stopped them if she wanted to. Which, of course, she didn't. But still.
They could do anything they wanted. She was helpless yet again. Doubly helpless this time. She looked back and forth between Laine and Maggie while they massaged her soft little titties.
Laine was always the easier one to read. She truly believed that he enjoyed playing with her boobies. He was a boy, after all.
With Maggie, it could have been a couple different things. It might just have been a bit of fun, or maybe she also enjoyed breasts in a naughty kind of way. It might even just have been a power thing. Some establishing of dominance over her baby sister. Catria didn't think it was necessary just because she'd burst in on Maggie changing, but one never could tell with these things.
Whatever the case actually was, Catria sat still and compliant for as long as her brother and sister wanted to play with her. Mostly they rubbed her tits with varying degrees of enthusiasm as the mood struck them, but she also happily spread her legs when Laine wanted to have a feel of her pussy.
She giggled maniacally when Laine nuzzled her neck and dropped a sporadic barrage of kisses. She was pretty sure he was getting horny again from the way he was acting. That was fine with her. She'd never stopped being horny.
Maggie was a little more teasing in her approach. Sometimes she just watched Laine play and sometimes she stroked Catria's tits, but occasionally she explored other areas. She traced fingers through her baby sister's hair, over her ears and neck, across her tummy and up her shirt.
It was all light, loving caresses until Maggie found a ticklish spot. Catria laughed and squirmed as her sensitive flank was attacked. Fighting only made Maggie tickle her all the fiercer.
The girls wrestled, with Catria at a severe disadvantage. She tried to wriggle away, but didn't have much room to maneuver. Her only weapons were her feet, so she ended up turned ninety degrees, butt toward Maggie, fending off further tickles with tactical kicking.
Maggie countered by targeting Catria's feet instead, which produced another flurry of helpless laughter. They were trickier targets though, and the girls eventually reached a stalemate of sorts and settled down again.
Catria was stuck in a more or less prone position across Laine and Maggie's laps. This turned out to be convenient for her siblings.
Laine was able to comfortably rest his hand on her breasts, and he took full advantage of the opportunity. With his other hand, he stroked her hair and occasionally traced her cheek and neck. Sometimes, when he got close enough to her mouth, she parted her lips and sucked on a fingertip for a few seconds before he withdrew again.
Maggie ran her hands over Catria's bare legs. She no longer tried to tickle her little sister, and instead explored a more sensual route up her inner thighs, and eventually to her panties.
Catria's breathing and heart rate grew fast and ragged under the combined assault of her siblings. There were so many hands and fingers running all over her at the same time. She couldn't keep up with everything, and eventually she gave up even trying.
She ended up focusing most of her attention on Maggie's fingers probing at her wet little pussy. Her big sister was being soft and exploratory, and generally just making her crave more.
Maggie took her sweet time. She rubbed up and down the front of Catria's panties until the material formed a small, damp valley along her sister's slit. She seemed curious as to what she was allowed to do, apparently not yet realized that the answer was basically anything.
It was true, Catria realized. She was ok with either of her siblings doing pretty well anything with her. Partly that was because she trusted them and knew she was always safe. Partly, too, was how much she liked being slutty around them.
She loved lying there being touched and felt by both Laine and Maggie at the same time. She loved that could both see just how wanton and compliant she was. She could be their slut. Their little sister-slut. The thought made her giddy.
The next time Laine's fingers approached her mouth, Catria caught one of them between her lips. Unlike previous occasions, she took it all the way in and sucked possessively. Laine regarded her curiously, but let her suck on his finger without trying to pull it away.
Maggie got her fingers under Catria's panties. She rubbed her sister's pussy with ever increasing confidence and boldness.
Catria rocked her hips gently, just enough to encourage Maggie's progress. She wanted more. She wanted some inappropriate sisterly attention. Some tender fingering. If it got rougher, that was ok too.
She moaned around Laine's finger as Maggie found her clit. That was the stuff. Getting her clit rubbed and tits played with, having something to suck on, being surrounded with sibling affection....
Catria's moaning turning into a muffled squeal of surprised excitement. Her panties were being tugged down her legs. She was perfectly fine with it, even if she hadn't expected it. She still squeezed her eyes shut at first, being slightly nervous to see Laine and Maggie's reactions to her revealed pussy.
"Aw, she's shy," Maggie said in a soft, teasing voice.
"Nah," Laine said. "She just acts that way." He removed his finger from Catria's mouth and wiped it on her shirt. Quite a bit of saliva had accumulated from being sucked on so long. "I'm quite sure she likes you looking."
"I have no doubt," Maggie agreed.
Catria shook her head while keeping her eyes tightly shut. Her face was delightfully warm, as was her pussy.
The brother-sister tag team was enhancing everything that would have been fun with just one of them. Teasing, embarrassment, sensuality, nervousness, and lust. They were all magnified, all made that much more potent when she was ganged up on.
Laine pulled Catria's top up past her breasts while Maggie fingered her wet little pussy. She gasped and wriggled while slender fingers penetrated her from one end, and slightly rougher fingers flicked and pinched her nipples from the other.
Catria was as exposed, helpless, and teased as she'd ever been in her life. She risked the occasional peek out between firmly shut eyelids just to make sure both her siblings' attention was on her, which it always was. She couldn't watch for long. Being essentially naked under constant scrutiny was thrilling and embarrassing enough without watching her watchers. She couldn't handle eye contact right now.
Maggie's fingers wormed about as deep as they were going to get inside Catria's tight pussy. Maggie wiggled them around experimentally, adjusting according to the way her sister moaned and writhed and clenched.
Catria couldn't believe the things Maggie was doing to her. Some of the sensations were beyond what she even knew were possible. Clearly she had some things to learn from her big sis.
It was really only a matter of time before Catria came. It was amazing she'd lasted as long as she had, really. She wanted to last longer, to feel more of what Maggie could do with her pussy, and generally just to soak in the heady mixture of intense feelings that surrounded and consumed her.
But her body needed release, and her pussy clenched and released repeatedly on Maggie's fingers as she came uncontrollably. She moaned incoherently and nearly rolled onto the floor by accident. Luckily Laine caught her before she fell.
She wanted to curl right up into a ball afterward. She felt so tired and spent, and more than a little vulnerable. It was one of the few times she regretted being handcuffed.
Her vulnerability and need to hide herself didn't last long. Her brother and sister changed back from sexual tormentors to their usual loving selves. Laine pulled her camisole back down and stroked her hair. Maggie left her panties wherever they'd ended up, but at least pulled a blanket over her lower half, providing both warmth and modesty of a sort.
Catria needed some cool down time. She wasn't sure if they understood that, or if they were just satisfied with making her cum the one time. Either way, she snuggled as comfortably as could be with them, and let their soft, familial caresses lull her back to a sense of security and love.

Laine uncuffed Cat that night so she could get ready for bed. He waited for her in her room while she finished up in the bathroom.
Cat was moving slowly and yawning pretty hard when she returned. Maggie hadn't given back her panties, and she hadn't grabbed a new pair, so she was still wandering around bottomless.
Laine tried not to stare at his sister's pretty little pussy despite how tantalizingly it peeked out at him. She'd had a busy evening and was clearly exhausted.
Cat walked up to him and turned around, assuming a familiar pose that had become second nature to both of them. She presented her wrists, he locked them together. She was all set.
He stayed and helped her get all tucked into bed, then gave her forehead a soft kiss.
"Good night, Cat."
"Mmm. Night."
Laine turned to leave and was just reaching to shut off the lights when he was called back.
"Laine?" Cat whispered.
"Yes?"
"Would you stay with me? Just for a bit?"
Laine hesitated. He was pretty much ready for bed himself. He was still in t-shirt and boxers, not totally stripped down but ready to fling off his remaining clothing a fall into bed.
But Cat was looking at him with big, needy eyes. They were practically shining up at him. She looked so adorable and lost. His brotherly instincts flared up.
"Alright," he said. "Just for a bit."
