@3

Cat smiled broadly, though with a sleepy crookedness. Laine flicked off the lights, then padded back and slipped in next to her. He had to scooch her over a bit to make room. She really didn't want to get any farther from him than she had to.

"Thanks," she whispered as she nestled against him. "I just don't really feel like being alone."

"No?" Laine patiently gathered loose strands of her hair and brushed them back from her face. "Something wrong?"

"No. M'jus a li'l tired is all. Today was crazy."

Laine chewed on his lip for a second. "Was it... too crazy? I mean, you know you can tell me to stop anytime you want. Me or Maggie. We don't have to--"

"No!" Cat burst out with sudden fervor. She buried her face in his chest for a moment, then continued in a calmed tone. "No, it's nothing like that. I loved it. All of it. Anything you do. I love all of it."

"But you'd say if there was something you didn't like, right?"

Cat didn't answer.

"Right?" Laine prompted again.

"I dunno. Maybe."

"Cat, you have to tell me you would. Otherwise we'll have to stop. I don't want to do anything you hate, or that's gonna do some kind of damage to you. I just couldn't risk it."

Cat nodded. "Ok. I'll say if something bothers me."

Laine was pretty sure she was just saying exactly what he'd told her to say. But then, that was about all he'd expected.

"Are you sure you're ok?" he asked again, just to be sure.

"I am now."

Laine repressed a sigh. The way Cat was cuddling, he'd never be able to slip away. And he was still a little worried about her. Possibly, though, she really was simply worn out. He was so used to her being a tirelessly horny imp that he wasn't used to seeing her crash.

"Do you want your cuffs off?" he asked. "Just for tonight?"

"No. I don't think I could sleep without them. I'm so used to them now. And they make me feel safe." Cat shifted a bit and her head came to rest on his chest. "But you make me feel safer," she whispered. "Safe and snug."

Laine melted. Any trace of annoyance vanished like magic. Goddamn she had him in her pocket. For a girl who spent so much free time without the use of her arms, she'd learned to exert an awful lot of control when she wanted.

"Is that why you always used to sneak into bed with me?" he asked.

"No. That was sleepwalking. You know that."

"Yeah, no, I know that. I just mean, like, maybe unconsciously. Or whatever."

"If it's unconscious, how would I know?"

"Nevermind." Laine patted her head. "Go to sleep, little one."

Cat giggled softly. "Ok. Love you."

"Yeah. Love you too."

Laine held her for a while longer until she was breathing steadily, rumbling gently against his ribs. Even then he didn't move, just kept holding her, feeling her warmth.

He must have dozed off. The next thing he knew, he was still in bed with his sister, but his chest had a damp patch from where she'd drooled on him. That and his neck was complaining from holding an awkward position too long.

Laine considered going to his own bed, but it seemed like too much trouble. And, if he was being honest, he didn't want to leave Cat. In the dark, small hours of the night, he thought he understood what she meant about feeling snug and safe. Probably not quite the same as she felt, but enough so that he didn't want to move.

He loved her. He'd always loved her, of course. She was his sister after all. But never like this. Never with quite the same intensity and need.

Well, that's what sex did to a relationship, right? He'd mixed it with family, and now he felt entirely the wrong things about his baby sister. He spent a moment wondering if that bothered him, then decided it didn't. Partly because he was sleepy and foggy, and not really up to tackling moral quandaries.

He carefully rearranged himself to a more standard sleeping position without disturbing Cat, then threw his arm around her and went back to sleep.

****

After suckering Laine into sleeping with her that first time, Catria couldn't go back to sleeping alone every night. The whole point of the handcuffs had initially been precisely so she would sleep by herself, but none of the siblings had any illusions that they were about that anymore.

Catria tried not to give in to her urges. She was perfectly capable of staying in her room and leaving her brother and sister in peace for the night. Sometimes she was even successful.

But something had changed. Falling asleep in her brother's arms had been one of the most wonderfully soothing experiences of her life. He was so warm and snuggly, and it just felt right drifting off next to him.

Even waking up beside him was different now. It used to be she'd feel embarrassed, or like she was being a pain in the ass. Those feelings mitigated the warmth and comfort of sharing a morning bed. These days, she didn't feel any of the bad things, only the good.

On the nights when she couldn't help herself, Catria would sneak into Laine's room and simply crawl into bed with him. No asking, no hesitating. He never said no, not anymore. Usually he'd wrap an arm around her or even just let her roll halfway on top of him and never say a word.

The more surprising thing was the way Maggie has started acting. Unlike Laine's general passivity regarding sleep arrangements, she took a more active approach in getting some sister snuggles. As far as Catria could tell, she'd figured out much the same thing regarding sleeping alone versus with a sibling and how much better the latter was.

Even better, to Catria's mind, Maggie sometimes played with her a bit before sleeping. It hadn't progressed past some fondling and fingering, but those remained delicious treats when they happened.

Part Four: An Incestuous Triangle

****

Catria woke up in Maggie's bed. She stretched lazily, then looked over at her still sleeping sister.

Maggie was sprawled haphazardly next to Catria, lips slightly parted in a soft snore. Both her and Laine had a unique peaceful look when they slept, Catria had discovered, an expression they never wore at any other time.

She lay and watched Maggie for a few minutes, content to be hypnotized by the slow, gentle rhythm of her sister's breathing. After that, she kicked at the covers until they tumbled to the floor off the foot of the bed.

The sisters were mismatched in their clothing. Catria was bottomless, having a camisole but no panties. Maggie wore only panties, and her breasts were fully exposed to the soft morning light.

Catria contemplated her nearly-naked sister. She was still envious of Maggie's slightly larger tits, but that was mostly just a background desire.

The bigger issue for Catria was determining how much of a lesbian she was.

She was fully aware that that wasn't really how it worked. It wasn't a matter of being a certain percentage straight and a certain percentage gay. She just didn't really know a better way to think about it.

She didn't feel the same things when she looked at Maggie as when she looked at Laine, that much was certain. She was far more traditionally attracted to boys than girls, just generally.

But she loved it when Maggie played with her. Absolutely adored it. And Maggie knew some amazing things she could do with her fingers and Catria's pussy.

When Maggie acted a little bit more dominant that usual, she could totally make Catria soak her panties. If she was wearing any.

None of which really provided an answer to Catria's questions.

The longer Catria lay there staring and musing, the hornier she got. Thinking about how Maggie made her feel led her to thinking about what she could get away with right now.

She'd awakened Maggie by sucking on her nipples once. That had been pretty fun. Maggie had smiled and chastised her in the sort of way that was clearly only for show.

Catria's pussy tingled as she thought about doing that again. She could dive right into that lovely soft cleavage and lick and suck and wake her sister up in no time.

Or she could be naughtier.

She contemplated Maggie's sole article of clothing, those little panties, and what lay beneath. Did she dare go for it? She wasn't totally sure how she felt about it, let alone how Maggie would take it.

As so often happened with Catria, once she had something naughty in mind, she found it very difficult to shake the thought loose. Her sister's pussy was right there for the experimenting. She liked sucking Laine's dick, after all. It couldn't be that different on an emotional level.

Catria scooted down between Maggie's legs. It wasn't going to be easy taking those panties off. Maggie was on her back, which helped, but it was still a daunting task.

Catria carefully leaned in, folding her body up to help her balance. She nearly fell right on top of Maggie a few times, but she managed to snag a bit of the panties between her teeth without real incident.

The first tug made very little progress, just barely enough to keep her thinking it was doable. She tugged again, then moved to the other side to balance out her progress.

It was hard work and took quite a bit of focus. Catria didn't want to nip her sister by mistake or pull too hard and make a total fool of herself. She got so absorbed that when she next looked up, Maggie was staring back at her with a bemused expression.

Catria bit her lip and waited. Maggie said nothing, just kept watching through heavily lidded eyes.

Catria took that for permission of a sort. She resumed her work, though with more situational awareness this time. She must have looked like a newborn puppy the way she'd been wrestling with Maggie's panties before. All determination and a greater sense of fierceness than was deserved, with very little actual progress to show for it.

At last she got past the tricky parts where Maggie's weight held down her underwear. Sliding them past her knees and calves was comparatively simple, though it meant some awkward maneuvering of her body, given her head's limited ranged of movement.

Again Catria looked to Maggie for permission or denial, and again found little of either. Mostly there was just curiousity and a hint of amusement.

She lay down between Maggie's legs, getting comfortable on her tummy. She had to worm forward a bit to get her face to her sister's pussy, and given her prone position she practically went face-first into it without really meaning to.

"Feeling naughty this morning, are you?" said Maggie in a lazy, melodic sort of tone.

Catria squirmed. "Kinda. Is it ok?"

"I would have stopped you before now if it wasn't."

That was basically what Catria had assumed. She studied Maggie's pussy from an extremely close distance. She still wasn't sure. It didn't call to her the way cock did, but it was intriguing and inviting in its own way.

More importantly, she was committed now. She couldn't back down. Maggie was waiting.

Catria stuck her tongue out for a long, ungainly lick. It didn't taste bad, nor did it taste good. She tried another lick of a similar nature. Again, a more or less neutral experience.

Then Maggie moaned. It wasn't a loud moan, in fact it was barely audible, but it was an indication of pleasure. That alone increased Catria's enthusiasm by several degrees.

Her wet little tongue flicked across Maggie's pussy. She gradually probed deeper and more purposefully. She got more sensual noises as a reward, and the taste got significantly better once juices started flowing.

Catria lost herself in her cunnilinguing for a while and only realized with a shock just how long she'd been going when her neck started to ache. She let her face rest more on her sister to take some of the strain off, then focused more on deft movements of her tongue to hit the places that got the best reactions.

"That's a good girl," Maggie whispered.

Catria flushed with a mixture of emotions at the slightly patronizing compliment. Sometimes those were her favourite kind.

Maggie reached down and put her finger to her clit. She held it there until Catria slid her tongue over it. Maggie bucked her hips when her clit got a firm lick, so Catria decided to do it some more.

Toward the end Catria was licking her sister's little clitty like it was her favourite treat in the world. Her neck ached more insistently and her back muscles were complaining, but she was getting so much positive feedback that she just didn't care.

Making Maggie cum was such a rewarding feeling. Catria could feel the impact in the way her sister tensed and moaned and went a little crazy with her hips. She'd never experienced a female orgasm vicariously before, and it was both enlightening and pretty damn hot.

Catria levered herself back into a kneeling position. She sat on her heels and waited with a shy but proud grin.

Maggie sat up. She was a bit flushed from her orgasm and still deliciously naked. She extended a finger, the crooked it back in a beckoning gesture.

Catria obediently shuffled forward on her knees. Maggie gently took her cheek, then leaned in.

Maggie's tongue flicked out and traced Catria's bottom lip. She momentarily considered the taste of herself on her little sister's face, then moved in again for a soft kiss.

"Did I do ok?" Catria asked, unable to last any longer without some verbal confirmation.

Maggie smiled a mix of amusement and sexual satisfaction. "Yeah, Cat. You did good." She reached out and gently brushed her sister's nipple with the back of her finger. "That was a hell of a way to start the day."

"Do you want me to do it some more?" Catria asked, bouncing with unrestrained excitement.

"That would be tempting," Maggie said regretfully with a last caress of Catria's tits. "But we have things to do. You're going to be late for school if you don't get moving."

"Oh, right. School."

Catria deflated a little, but was still gleeful and horny as they got out of bed and she was unlocked. She stretched her arms and headed for the door.

She'd become so used to a lack of proper attire that she nearly forgot she was bottomless until she reached the doorway. She caught Maggie staring at her butt out of the corner of her eye as she swung the door open. She smiled to herself and gave her hips a bit more sway as she walked away.

The shower was already running before she got to the bathroom. She went in anyway.

"Morning, Laine," she called in a sing-songy voice while pulling off her camisole, the only clothing she'd been wearing.

"I suppose privacy for showering was too much to ask, was it?" he replied in a tone that suggested he already knew the answer.

"I'm gonna be late," Catria said as though that was really her reason for barging in. "Can I hop in with you?"

She stood there naked and horny, awaiting her brother's decision. She'd wait for him to finish if she had to, but she was really hoping for some play time. She was going to be a gooey mess all day if she had to go to school in her current state.

"Yeah, alright," Laine finally said.

Catria eagerly pulled back the shower curtain and jumped in with him. He was all wet and naked, as was she once she stood under the spray for a moment.

Laine's cock was already stiffening. Catria grinned and reached out to grab it and help it along. She slid her loose fingers along its slick, semi-firm length. Back and forth, back and forth. It pulsed and expanded in her hand, soon reaching full hardness.

It fascinated Catria the way her brother's penis went from soft to hard like that. She didn't usually get to feel the transition, and in her already horny state it was an extra little delight on top of everything else.

"I thought you were in a hurry," Laine said.

Catria looked back up at him, having halfway forgotten that he was still attached to his cock. "I guess I kinda am," she said regretfully. She turned around. "Can you wash my back for me?"

She started on her front while Laine got her shoulders and worked down from there. As she hoped, he didn't stop at her waist and simply carried on to her butt. He spent more time soaping, massaging, and rinsing her ass than necessary, and she enjoyed every second of it.

Only when he finished a very thorough cleaning of her bottom did Catria move from her statue-like stance. She took a careful step back, which pressed her butt nicely against her brother's hard cock.

"Not that much of a hurry, then," Laine murmured.

Catria smiled to herself and wiggled her ass. Laine's hardon slipped around a bit, then lodged itself in her butt crack. Her wiggling transitioned to more of a grinding motion.

She felt her pussy heating up even more the longer she toyed with her brother's penis. She was teasing herself as much as him.

Thankfully, Laine wasn't able to hold out any longer. Despite his apparent concerns for the swiftness of her shower, his hands snaked under arms and found her tits.

Catria giggled happily and gave her hips another firm thrust back against him. He was grinding as hard as she was now.

Their bodies rubbed sensuously together under the warm cascade of water. Brother and sister locked together in a wet, lustful embrace. His hands were all over her tits, while she reached behind her head to find his shoulders and neck.

Laine pulled away from Catria's butt. She tried to follow his movement, but he wasn't going far. When he pressed forward again his cock slipped beneath her ass and between her thighs, grinding on her sodden pussy instead.

That was way better. Catria cooed wantonly as her brother's dick rubbed all over her wet slit. She bounced around against it, squeezing every ounce of pleasure she could from the contact.

There were a couple moments where she was sure he was going to slide right in. They were both wiggling and grinding like crazy, and all it would take was his cock lining up just once. Laine probably wouldn't let it happen, she assumed, but if he did... well, she certainly wasn't going to stop him.

Catria eventually had to give up on her private little fantasy. It wasn't happening by accident, and she wasn't quite brave enough to try and force the issue, though it was a close thing.

She reached down and grabbed the end of Laine's cock where it poked through beneath her. She held it more firmly to her drenched cunt and slid her palm up and down, giving them both a little extra stimulation.

White gouts of cum spewed out of the tip of Laine's penis. Catria clasped her hand around it, feeling the tensing and pulsing of his orgasm. She stiffened, pressing harder, rubbing more furiously, and reached her own orgasm just as his was ending.

Laine's arms around her kept her from stumbling on the slippery floor and her own shaky legs. She leaned back against him until she could restabilize. Then, slowly, carefully, she turned around, pressed her slick breasts against his equally wet chest, and kissed him.The kiss was longer and deeper than Catria had really intended. She just didn't want it to end once she'd started. She felt so good, so goddamn magical, and she wanted the remnants of that sensation to last forever.

The moment was broken by the sound of someone peeing in the toilet practically right next to them. Catria and Laine turned their heads as one, and after a second of hesitation she started giggling uncontrollably.

"I really can't get any privacy," Laine complained without malice.

"I might feel bad about that if you didn't sound like you were having quite so much fun," Maggie retorted from the toilet. "I couldn't wait forever for you two to finish... whatever it is you're doing."

"Just getting cleaned up," Catria said innocently.

"Yeah. I'm sure," said Maggie in the sort of tone that suggested she'd sooner believe the world was flat. "Just don't be too long."

"We won't," said Laine. "But please don't flush until we're done."

"I might have to if I want to get you out before all the hot water's gone."

"You could always join us," Catria said, still in a slightly dazed state. In her head, being sandwiched between two naked, slippery siblings was even better than just the one.

"In your dreams," Maggie said.

There was the sound of the tap in the sink running, then footsteps out of the room.

"Guess we better finish up," Laine said, giving Catria's bum a final squeeze.

"Yeah. I guess."

****

Cat was gone by the time Maggie finished her shower. Laine was still hanging out in the kitchen, half-heartedly scrubbing at some dishes in the sink.

Maggie poured herself some coffee, then perched on the edge of the counter to sip at it. Her bare legs dangled whimsically, kicking gently to an unheard rhythm. She'd only dressed in a shirt and panties after her shower since she still had time before she needed to leave for work.

"Shower sex this morning, huh?" she said aloud.

Laine faltered and carefully set the plate he'd been holding back in the water. "It wasn't sex, exactly."

"You don't need to be defensive about it. I was just asking."

"No, you weren't just asking. I don't know what you were implying, but it wasn't an innocent question."

Maggie toyed with the accusation. "You might be right." Her legs went still and she gripped her mug with both hands. "I guess I've just got Cat on my mind. She's been getting bolder. Practically every day it feels like. Wearing fewer clothes all the time."

"It doesn't even surprise me when she turns up naked for no discernible reason," Laine agreed. "Or when she decided just to hop in the shower with me."

Maggie smiled faintly. "You know she ate me out this morning?"

Laine gave her a slightly incredulous look that slowly morphed into something more thoughtful and interested. "I didn't think she swung that way."

"Neither did I. But then, it's very hard to tell. She responds better to dominance and naughtiness than gender or any particular sexual activities." Maggie shrugged. "At least from what I've seen. I've got a pretty small sample size to work from. But for what it's worth, she tried to get at my vagina while I was still sleeping this morning."

Laine nodded slowly. "Well, that is quite naughty."

"Isn't it though. She was lucky I was in the right mood for it, or I would have had to kick her out of bed. I can just imagine the sad puppy look she'd give me."

Laine gave up on his dishes and let the water out of the sink. He wiped his hands on a towel. "She's not going to grow out of this, is she?"

"Not for the foreseeable future. It's only getting worse. Or better, depending on your point of view."

"So what do we do?"

Maggie sipped her coffee. "Embrace it."

"Embrace it? Isn't that what we've been doing?"

"More or less. But I mean really accept it for the long term. Not just play along until she has a change of heart."

"Ah. I see." Laine considered. "And what does that entail, exactly?"

"Well, for starters, Cat's graduating high school soon."

"Yeah?"

"And it might be a good time to get her a present."

"Ok. But that would be true regardless. Graduation presents don't have anything to do with our situation in particular."

Maggie smiled faintly. "Just trust me on this one."

****

A couple days later, Laine was staring bemusedly at the sign of a sex toy shop. "You know, this really isn't what I thought you meant when you said you wanted to get Cat a graduation present."

Maggie took his hand and guided him to the entrance. "I know it isn't. But if you have a better idea, I'm open to it."

"I really don't. It's probably a good idea, it's just... weird."

"How so? You can't be that embarrassed about giving her a sex toy."

"I'm not. I'm embarrassed about shopping here for one sister while accompanied by another."

"Oh, yeah. I guess that is kinda weird, isn't it? I wasn't even really thinking of that angle."

There was one other customer in the store already, but they were at the register and presumably on their way out. Laine was relieved by that. He'd had a horrible image of several people milling through the shop, one of whom would recognize him and Maggie and get very curious about them being there together.

"You can let go of my hand now," Laine whispered.

"Not yet," Maggie whispered back.

"Why not?"

"Because I'd rather look like a couple than like siblings."

"I really don't think that's where most people's minds would go."

Still, Laine felt better knowing that he wasn't the only one feeling a bit strange about their visit. Shared discomfort was preferable to lonely discomfort.

He and Maggie browsed the selection of toys and miscellany. Neither of them were totally sure what they were getting. It was the right place to look, though. Laine could admit that, even if he wasn't totally happy about it.

"What about a new vibrator?" Laine asked. "Her old one's been putting in some hours."

"I dunno how much she actually uses it these days," Maggie said. "She's been sleeping with one of us more often than alone."

"Oh yeah. That's true."

Maggie released his hand and started picking up and examining toys. She was far more curious and thoughtful than he felt. He really kind of just wanted to pick something semi-normal and get out of there.

Whenever he wasn't looking toward the girl at the counter, he imagined her watching the two of them with an amused expression. That was unfair, he knew. She'd showed no sign of being anything other than professional. She'd have to be if she didn't want to scare of the more nervous of the clientele, working at a place like this.

Still, Maggie was in no hurry. Laine had time to get over his initial hesitation and begin examining the merchandise with a more critical eye. And his mind had a chance to warm up and start picturing some of the toys being used on Cat. There were some very interesting possibilities.

****

Catria was totally unaware of her siblings' shopping trip. It wasn't uncommon for either or both of them to be late getting home, though she wasn't much a fan of those occasions. She much preferred having either Maggie or Laine around to tease or play with, or even just to be a presence in the room.

The house was too lonely when she was by herself. It used to be that a little time with the run of the place was a nice treat. These days, there really wasn't anything she could be doing by herself that she wouldn't rather do with her brother or sister. Or both.

There was no thrill at all to wandering around partially or fully naked when there was no one to see her. She'd gotten into the habit of dressing in a shirt and no bottoms on a semi-regular basis, and that's exactly what she wore while waiting for someone to get home. It just wasn't exciting by itself the way it used to be.

She still enjoyed her naughty attire. It was fun when the moment finally came for her to feign boredom when Laine or Maggie walked in and realized she wasn't really dressed. She just wished it did something for her in the meantime, was all. Casual nudity had lost some of its magic.

That was ok, though. Nothing stayed quite as exciting as it started. And there were always new thrills to discover.

But for now, Catria was bored. She'd tried to take advantage of her alone time to do some school work. That had kept her busy for a little while. She'd made it more interesting by lying in the middle of the living room with her books and papers in front of her and her ass tactically pointed toward the doorway.

There'd been no payoff, though. No lustful siblings arriving to find a slutty, half-naked sister waiting for them.

Catria had proceeded to stare out the window for a bit, as though watching the driveway would make a car appear faster. It didn't.

She'd even tried one of Laine's games. She'd started it up without bothering to change the game that was already loaded. It didn't make much difference to her since she didn't really keep up on that sort of thing. It hadn't mattered anyway. It had taken forever to start a new game and get through all the introductions and cutscenes and such. By the time she was allowed to play, she'd lost interest.

It was a little depressing in some ways that this was what her life was reduced to. It used to be that she was fairly independent of her siblings and didn't need them around to entertain her.

On the other hand, when they were around she was happier than ever, and more excited about new possibilities. Catria wouldn't trade back for anything.

She ended up eating a mopey supper alone in front of the tv. Microwaved pizza pockets, with their traditional swirls of not quite warm bits right next to molten lava bits. Picking at them without burning herself kept her mind occupied, at least.

Maggie finally walked in the front door followed closely by Laine. She held the door for him since he had a bag in each hand.

"Finally!" Catria said, bouncing out to meet them. "You guys took forever."

"We had some shopping to do," Maggie said, stopping to hug her excited little sister. "Then we stopped for some food. Didn't you get our texts."

Catria drooped. "Oh, right. I might've left my phone in my room."

"If you'd wear pants now and then, you'd have pockets for carrying your phone in."

"Yeah, but I'd have to wear pants."

"So you would." Maggie swatted Catria's butt. "Give us some room, would you?"

Catria stepped back while her siblings decided whose bag was whose, then proceeded off to their respective rooms. She tailed along, slightly hurt that they weren't paying her enough attention. "So what'd ya get?"

"That, dear sister, is none of your business," Maggie said.

"It's a secret," Laine added.

"Dammit, Laine," Maggie said. "Don't tell her that."

"A secret?" Catria asked, perking up a little. "What kind of secret? Something for me?"

"See?" Maggie said. "Now she's gonna be even nosier."

Laine chuckled. "Sorry."

"Hey, don't ignore me," Catria said. "What kind of secret?"

"You must not understand how secrets work," Maggie said before tromping definitively off to her room and shutting the door.

Laine was probably the weaker link anyway, Catria decided, so she continued to shadow him instead of laying siege to her sister's room. She slipped into his room right behind him before he could even think about barricading himself inside as well.

"You should just tell me," Catria said. "I'll have to bug you otherwise."

"I can't. I answer to a higher authority."

Catria frowned. "Like... a god of some sort?"

"No. Maggie. She'd be very annoyed if I spoiled the surprise."

"How come she gets to be the higher authority?"

Laine arched an eyebrow. "Are you really asking that? You who takes every opportunity to submit to our authority whether we want you to or not?"

"That's not what I do."

"Uh huh." Laine sat on his bed, clasped his hands, and gave her a steady look. "Take off your shirt and go fetch your cuffs."

Catria automatically reached for the bottom of her shirt before realizing he was making a point. "Oh." She bit her lip. "Ok, so maybe I kinda do." She straightened up and set her jaw. "But I could be authoritative if I wanted."

"Yeah? Try it."

"Ok." Catria cleared her throat and adopted her firmest tone of voice. "Show me what you bought."

"Or what?"

She hesitated. Was there meant to be an 'or?' "Or... or... I'll spank you?"

Her tone had become rather meek and uncertain toward the end, rather ruining any effect it might have had, which probably wasn't much based on the way Laine was grinning.

"Very good effort," he said.

"No it wasn't."

"No, you're right, it wasn't."

He reached out and grabbed Catria. She squealed and fought him a little just for show, but went docile pretty quickly as he dragged her across his lap.

Laine gave her a few quick, light slaps on her bare butt. Not enough to hurt or even sting, just a playful little spanking. She giggled and kicked her feet, hoping for more.

"You're about as submissive as they come," Laine said. "And you're not shy about it, or about what you want. It's an odd combination, really."

"It is?"

"It is," he confirmed. "And I kinda love that about you."

Another couple smacks, then Laine let Catria go. She stayed right where she was. She gave her bottom a little shake just in case it would tempt him into spanking her some more.

"I'm happy," she said. "With you and Mags. With everything. And I think...." She paused to consider, then decided she meant what she'd been going to say. "I think I wouldn't be this way with anyone else. It's just 'cause it's you two, and I know I can trust you with anything."

"Of course you can," Laine whispered.

Catria smiled. "I like surrendering control and just seeing what happens. And sometimes I like making something happen myself, because let's face it, you're both gentler with me than you need to be."

"You're our sister. Of course we're gentle. I keep half expecting you to change your mind and decide you don't actually want to be messing around with either of us. And if that days comes--"

"It won't!"

"If it comes," Laine repeated, "I really hope that we haven't gone too far already." He patted her butt reassuringly. "Maggie's working on convincing me that we aren't going back."

"She always was a little quicker than you."

Catria's teasing quip earned a much sharper smack on the ass. This one stung a bit and made her yelp. Her pussy felt that much warmer all of a sudden.

"Maybe I'm just the responsible one," Laine said. "Ever think of that?"

"I dunno. I think that might be Maggie too."

"Great. So what do I get to be?"

Catria pretended to think hard. "The token boy?" she suggested.

Laine sighed. "For someone who's trying to get information out of me, you're being awfully sassy."

"Ooh, I almost forgot about that. So what did you get me?"

"I guess that's my own damn fault. Shouldn't have said anything."

Catria wiggled on Laine's lap. "Tell meee," she whined.

She smiled privately at the way her tummy was jabbed when she moved the right way. He was so hard.

"You reeeaaallly want to know?" Laine asked.

"Yes!"

"Because I definitely can't tell you the main thing without Maggie getting quite perturbed. But we did end up going a little overboard...."

"Ooh, does that mean there's more than one surprise?"

"Kinda, I s'pose." Laine's hand rubbed small circles on Catria's butt. "The problem is I'm not sure how you'll feel about what I have in mind."

"I feel really good about it."

"You don't know what it is."

"So tell me. Then I'll feel really good about it."

Laine continued to toy with Catria's bum. His fingertips danced between her cheeks and flitted across her asshole. She was kind of intrigued, but didn't think much of it beyond that.

"How do you feel about, like, butt stuff," Laine asked.

"Like what you're doing now?" Catria asked. "It's pretty nice."

"No. Like, real butt stuff."

Her eyes widened as Laine's fingers brushed her butthole again. "Like... inside butt stuff?"

"Yeah."

Catria swallowed, her mouth suddenly dry. Nervous butterflies swarmed her tummy with an abrupt vengeance. She'd been caught almost entirely unprepared by the question.

Laine loved her butt. She knew that, and kind of adored it about him. She, in turn, was quite happy to show it off and let him play. But actual, for real butt stuff was something else entirely.

"Yes," she croaked before her mind had really caught up.

"Yes?"

Catria nodded. "I'm ok with it."

She wasn't yet totally convinced herself, but that didn't really matter. She felt nervous and horny and a little bit scared. A combination that did wonderful things to her insides, and which she didn't experience nearly enough lately.

"You don't sound sure," Laine said.

"I'm sure. I just haven't really done it before."

Laine's finger pressed against her tight little hole. He didn't seem to be actually trying to force entry yet, which was good because there was absolutely no lubrication to help him along yet.

"We don't have to or anything," Laine said. "It's just something I was thinking about."

"Oh my god," Catria said. "I told you I want to."

"That's not what you said."

"Well... I'm saying it now."

Laine was quiet a moment, though he kept fondling Catria's bottom. "Fine," he said. "Hand me that bag, would you?"

The bag he'd come home with lay next to his bed. Catria was just barely able to reach it without falling off his lap. It was tempting to tear it open and peek inside, but that might annoy him, so she was good and handed it over. He peered inside, then pulled out a brand new bottle of lube.

"Of course, Maggie thinks that playing with your butt is more to satisfy my own interests than to do something nice for you," Laine said.

"Well that's true, isn't it?" Catria asked.

"Yes and no. I mean, it's definitely kind of a selfish gift, I can't really argue with that. But I think it's the sort of thing you'll enjoy."

"You think I'm the sort of girl who's gonna really enjoy anal?"

"I think you're the sort of girl who really enjoys doing naughty things with her brother."

Catria had to admit that he had a point there. Whether or not she ended up enjoying the physical sensations, she was already pretty turned on by the mere act of lying across her brother's lap and waiting for him to do severely inappropriate things to her butt.

She tensed instinctively as cold lube was drizzled over her asshole and the surrounding area. The shock went away quickly. Once Laine started rubbing it in, she folded her arms under her head and settled in to enjoy the feeling.

"You really like my butt, huh?" Catria said softly.

"You know I do."

Laine's middle finger had been circling its target. Now it probed gently at her butthole, testing her defenses.

"How long have you been thinking about this?"

"I'm not sure, exactly." Laine paused to consider. "At least since you started wandering around the house naked from the waist down. That's been driving me kinda crazy."

Catria giggled softly. "That was the idea."

Her mouth formed a small circle as Laine's finger finally slid in. It was only the barest of penetrations, just past the outer ring. She waited to see if her body would tell her it hurt.

In fact, it neither hurt nor felt particularly pleasant. It was quite a neutral sensation, physically speaking. Mentally, however, it was so much more.

Catria arched her back, then calmed herself with some deep breaths. She didn't want to tense up.

Laine pulled back, picked up some more lube, then returned even deeper. His finger wiggled inside her, ever more intrusive.

She'd secretly hoped it would be more dramatic. That it would hurt terribly to be even gently fingered, or perhaps that it would make her whole body tingle and she'd cum within minutes. Or, indeed, that she'd feel horribly embarrassed and have to remain silent through an agonizing ordeal.

But such was her comfort with Laine that she didn't feel any mental anguish, to her disappointment. It was fun lying there and being a bad girl, letting her brother finger her ass, but it wasn't much more than that. She was used to him seeing her unclothed, and to his touch on her intimate parts. This was a novelty, and that was all.

"Is that ok?" Laine asked.

Nearly his whole finger was in by that point.

"Yeah, it's fine," Catria said.

"You almost sound disappointed."

She shrugged. "I dunno. I thought it'd be more intense."

"Intense, huh?"

Laine pulled his finger out, then pressed a second finger right up next to it. Together, they didn't slip right back in.

Catria stretched away from the extra intrusion. "Well that's too much."

"One's not enough, two's too many?"

"Seems that way."

Laine placed his free hand on the small of Catria's back. He let its weight sit there, solid and comforting.

"They'll fit," he said.

Catria shook her head. "They won't."

"Trust me."

She bit her lip. Her heart was speeding up and she was getting nervous tingles. That was more like it.

"Ok," she said faintly.

The delicious anxiety that turned Catria on like crazy was usually more a fear of emotional pain than physical. This, it seemed, was going to be different.

Part of it was her own fault too. She deliberately psyched herself out and anticipated something much worse than she actually believed in. It got her so damn wet.

Laine took his time. Even more so than his first, single-digit penetration he applied gentle pressure alternated with soft circling and stroking. He took long enough that some of Catria's carefully nurtured tummy butterflies went back to sleep while waiting.

Then, catching her very much off guard, Laine's pair of fingers popped in.

Catria raised her head, mouth opened in advance of a shriek. There she froze, right on the verge of making some terrible noise, before slowly subsiding again.

It hurt a little. Enough that her reaction was more than just shock, but not so much that she felt compelled to end it. She bit her lip and pulled over Laine's blanket to bury her face in.

"Oh shit, that hurt, didn't it?" Laine said, quickly withdrawing.

Catria didn't answer. Laine rubbed her butt without approaching her asshole.

"A little," she grudgingly admitted.

"Sorry."

Catria shrugged. She lifted her hips and wiggled them.

"You can't be serious," Laine said.

Still she said nothing.

He couldn't resist. She knew he couldn't. He held out a little longer, then his fingers pressed to her butthole again.

This time they went in easier, and already the pain was a dull echo of before. Catria clung to that small ache, letting it feed her masochistic little pussy.

Laine pushed deeper with the smallest, gentlest thrusts of his fingers. They didn't get sharply wider after the initial penetration, so there wasn't as great a need for going slow anymore.

This time Catria enjoyed feeling him get deeper inside her much more than before. Now it meant something. Now she could really feel it, both the pleasure and pain.

She rocked her hips in sync with Laine's thrusts. Neither of them moved particularly hard or fast, but participating in her own anal training gave her a bit of that slutty feeling that she lusted after.

Her finger-fucking got smoother and more rhythmic as her ass adjusted. Her nervous thrills gave way to a calmer but no less enjoyable sexual pleasure as her brother toyed with her bum. His fingers were just enough wider at the base that she still experienced a slight stretch at the end of every cycle, before then tightening up again when he pulled back.

Catria was really getting into it, and was therefore disappointed when Laine stopped fingering her bottom. She looked back over her shoulder with a pout all ready for him, but he forestalled her objection by pulling something interesting from his shopping bag.

"You did get me something," she said with barely contained excitement and curiousity.

"We've already established that."

"I know. I was kinda worried you were gonna call a bottle of lube my present."

Laine snorted. "That was more a present for me."

Catria stretched out, taking the break as an opportunity to rearrange herself slightly and get more comfortable. "I liked it though."

"Did you? Or are you just saying that because you know it turns me on?"

"Both."

Catria watched with curious anticipation as Laine unboxed her new toy and took it out of its plastic. After learning how well her butt could take his paired fingers, she was pretty sure she could handle this too. That didn't stop her nervous uncertainty from returning, however.

"It's a butt plug," she said.

"Sure is."

"It looks kinda big...."

"It's really not." Laine held the plug against his hand for comparison. "It's maybe a bit wider than my fingers. And that's only at the widest part."

"Yeah, but still."

Laine was already lubing up the plug. "Are you telling me you don't want to try it?"

Catria squirmed. Part of her was saying exactly that. The rest of her was all gooey at the idea of her brother somehow sticking that butt plug inside her.

"No," she whispered.

"No you're not saying that, or no don't do it?"

"The first one."

Laine patted her butt. He grabbed an ass cheek with one hand and spread her a little while he pressed the plug to her butthole.

"You want this inside you, don't you?" Laine said.

Catria nodded. Her pussy was on fire at the thought of being such a little butt slut. "Yes."

The tip of the plug popped pat the outer ring of her ass. It was more than a finger, but less than she'd already handled so far.

"All the way in," Laine whispered, his voice taking on a more excited tone.

"Yesss," she hissed.

Still more of the plug slid inside. It was getting wide now. Wide enough for it to start affecting Catria in a physical way.

"There it goes," Laine whispered with intense fascination. "Like you're already a pro."

It was a nice idea. Catria knew it wasn't nearly true, however. They met resistance at the widest part of the butt plug and had to slow down.

She wondered if that was what she was destined for. To be a 'professional' little sister butt slut. Whether Laine was going to want to do stuff like this all the time now that she'd assented once.

God she was bad. She was already imagining more, and they weren't even done.

Catria moaned and gradually transitioned to more of a whine as the widest part of the plug stretched her ass out, but didn't quite make it. She was almost there. She was determined now, and had no intention of quitting.

Laine's patience helped. He was so careful about watching and listening, going slow and gentle. He didn't rush things. The small instances of pain never passed beyond an enjoyable level.

"I can do it," Catria said.

"I know you can. You're so close."

She smirked over her shoulder at him. "You know, if you weren't so interested in my butt, you wouldn't have let this get so far. You would've been too afraid of hurting me."

"Maybe I'm starting to figure out what you can handle."

"Yeah. Or maybe you're just horny."

"Maybe I am."

Laine gave Catria's butt a sharp smack. She giggled happily. However, she also bucked her hips in what was meant to be a playful acceptance and desire for more, but ended up accidentally pushing the butt plug the rest of the way in. It popped smoothly into place once the widest part slipped past the former barrier of her anal ring.

Catria lay frozen in shock for a moment. Once again, there was a flash of pain that she couldn't quite decide how to handle; whether to scream out or grind her pussy against Laine's leg.

"Cat?" Laine asked with a note of worry.

"I'm ok," she breathed.

"You went kinda quiet there."

"I know."

Catria squeezed and relaxed her various muscles. Now that the plug was fully embedded, any little shift in the area felt really quite interesting.

Her pussy begged for attention. It had been ignored so long while her desire mounted. Her filled bum made it all the more jealous.

"It's too much," she whispered.

"You want me to pull it out?"

"No. I need to cum."

"Oh." Laine laughed. "Well I'm right there with you."

Catria had somehow restrained herself enough to not rub herself silly. She wanted Laine to play with her and get her off. The anticipatory wait was exquisitely excruciating.

She squealed her protest as she was thrown off her brother's lap. That was the opposite of what she wanted.

"Hey!" she said.

"What?"

Laine stood and began pulling off his clothes. This immediately mollified Catria who proceeded to curl up and watch the show.

She liked seeing him naked. Even better that he was getting naked specifically for her. Better still, more naughtiness was coming.

Catria kind of hoped that he'd want a blowjob. Although actually, her body was practically demanding some pussy play time by this point, so maybe he'd eat her out first. Mmm. That'd be nice.

She bit her lip, vibrating in impatient anticipation. Laine was nearly tearing his clothes off, and it still wasn't fast enough for her.

He finally pounced back onto the bed, fully naked, fully hard. He landed next to her and immediately sought a kiss. She returned it, though still squirmed for more.

"I want you so bad right now," he whispered.

"Me too." Catria ran her hands over Laine's chest. "My pussy needs you," she murmured in his ear.

His cock poked her thigh. His hips moved in small, needy motions, grinding against her.

"You're bad," he said.

"I am."

"Lucky for you, I might just be as bad as you are tonight."

Catria didn't believe that, but she wasn't about to argue. She assumed they were on the same page, and that she was going to get some desperately needed pussy licking. She was wrong, but in just about the most wonderful way possible.

She gasped and instinctively wrapped her arms around Laine as his cock bumped closer to her hot little cunt. It could have been just an accident, but she knew it wasn't. He was pressing, thrusting, getting ever closer. It was actually happening.

Catria reached down and grabbed her brother's full, throbbing erection. She guided the tip to her wet, eager slit, then gasped as a small thrust of his hips parted her pussy lips.

"Yesss," she hissed.

Laine kissed her fiercely, nipping at her bottom lip as they parted. She grabbed his neck and pulled him back for more.

There was an urgency to the rolling of their hips, a lust that needed to be satisfied. Catria's pussy swallowed every little bit of Laine that he gave her. His initial small thrusts gave way to longer and deeper movements, made all the more powerful as she pulled him into her.

Catria purred her satisfaction as Laine bottomed out inside her. Her little snatch was all filled up by her big brother. His cock and her butt plug rubbed together with only a thin layer of her own body between them. It was truly naughty little sister heaven.

"You're inside me," she whispered.

"I am," Laine agreed.

Catria gazed at him adoringly. "I love you."

He smiled back, then kissed her. It was probably their longest, most lingering kiss yet. Neither wanted to break it. They took small pauses for breath, but their lips never fully parted.

Catria writhed sinuously and purposefully beneath Laine. She wanted to touch him everywhere, to feel their bodies pressed as close as possible. Her hips were in constant motion, acting in time with his.

She was totally in love with the feel of his cock thrusting in and out. The small empty feelings when he pulled back only made the moments of true fullness that much better. The instant when he'd buried himself in her and still had a little extra momentum like he could keep going if only physical constraint allowed, that was her favourite.

Every now and then she gave her hips a bit of extra kick to make their contact harder, and just a tiny bit painful. She cherished the ache and hoped she'd feel it for days to come. She wanted a reminder of fucking her brother for the first time that lasted days, if not weeks. Foolish, romantic sentiment though it may have been, it drove her crazy thinking about it.

Catria came forcefully, propelled by vaginal and anal stimulus working in harmony, as well as the omnipresent thrill of being with Laine. Waves of incestuous pleasure overcame her, ruling her body in her mind's absence.

Laine slowed his thrusts as she came back to reality. He pushed up to his knees, his cock reluctantly sliding out of her.

"You don't have to stop," Catria said in a lazy, satisfied voice.

"I know. I just wanted to look at you for a minute."

She blushed and averted her eyes, then peeked back shyly. She felt special and sexy that Laine would actually take the time in the middle of fucking her to just look. But she also wanted him to keep going.

"Take your shirt off," Laine said.

Catria smiled and sat up to pull her top free. "Sure."

Laine took her shirt and began twisting it up. "Roll over."

"What? Why?"

He didn't bother explaining. He simply took hold of Catria and bodily flipped her over.

She shrieked and giggled, then got her knees under her and lifted her butt in the air. She wiggled wantonly with her face still down on the bed. If that was all her brother wanted, a different angle of penetration and a better look at her ass, she was perfectly happy to oblige. Thrilled, even.

Laine took her wrists and placed them both behind her back. She obediently held them in place while he tied them together with her shirt. It wasn't a great rope, and she was pretty sure she could have worked free with a few seconds of hard tugging, but she let her arms rest loosely against their bonds. It wasn't too much of a stretch to pretend that she was tied up and helpless to being further ravished by her brother.

Catria moaned long and low as Laine sank back inside her. It was a subtly different experience being penetrated from behind, physically speaking. More important and exciting were the mental aspects.

It felt so much more like Laine was in control and getting what he wanted, which was at least partly true. Catria was bound and plugged, with her pussy presented submissively for her brother to use as he desired. She loved it.

Laine's fingers dug firmly into her hips and ass. He used the added purchase to thrust into her all the harder.

Catria moaned her encouragement and moved along with him, not making any attempt to wrest control back or set a different pace. She'd be a good little sister and let her brother get off any way he wanted. Though considering how much the thought turned her on, it wasn't exactly a selfless gesture.

Both siblings moaned and breathed harder as Laine pounded Catria's soaking pussy. There was no talking, no thinking, not even much for love or romance remaining as they were overruled by lust and need.

Catria gasped as her butt plug was pulled out to almost the widest part, then allowed to slide back into place. Laine did the same thing a couple more times, then pulled it back even further so that it popped past her anal ring.

She came again while getting fucked in both her ass and pussy. She mewled and alternated stiffening and relaxing as each pop of her butt plug sent a little extra jolt through her already pleasure-wracked body.

Laine's pace had become frantic, and he seemed to lose control even further as Catria's pussy spasmed around his dick. He pounded her hard and deep, then abruptly pulled out.

Hot cum splashed across Catria's ass. She bit her lip and her eyes rolled back in total sexual overload. Brother-cum on her butt on top of everything else. Delicious.

Laine crawled over to the side of the bed and slouched with his back to the wall. Catria fell on her side and curled her legs up partway to her chest. They stared at each other for a few moments.

"I'm sleeping here tonight," Catria said, just in case there was any question.

"Fair enough," Laine said. He reached out and ruffled her hair. "I didn't really expect anything else."

Catria wormed a little closer so she could get better head scratchies. "I liked my present."

Laine snorted. "What part of it?"

"All of it. Everything." She smiled with a lack of any particular focus. "It was wonderful."

Laine twirled a lock of her hair around his finger. A smile grew wide across his lips. "It was, wasn't it?"

****

The siblings didn't much move from Laine's bed that evening. Laine sent Cat to the bathroom and made sure she got cleaned up and ready for sleep, then retied her arms with her twisted up shirt. He thought she'd prefer her handcuffs, but apparently, so she claimed, it would be too much work to go find them.

That was fine. She seemed happy enough with her arms in their makeshift binding, and a total lack of clothing other than that.

Cat fell asleep long before Laine did. He stayed up, propped up on his pillow and headboard, little sister nestled against him. He watched her sleep, and occasionally toyed gently with her hair or traced her soft, delicate skin.

He didn't feel even a little bit bad about what they'd done, much to his relief. A large part of his fears had always been about how he'd feel after something happened, rather than how worried he was before or during.

It felt right. That was all he could figure. He and Cat had definitely gone a bit crazy, a bit overboard, but that didn't have to be a bad thing. She'd fallen asleep with the happiest smile he could ever remember on her, and even now her peaceful expression contained traces of her pre-sleeping joy.

He loved her so much it actually hurt.

Laine didn't stir when the door creaked open. Possibly he should have felt guilty, should have tried to hide what he'd done from Maggie, but he didn't much care to. He simply looked up at her with one curiously arched eyebrow.

"She's asleep," Laine said softly.

"Yeah. I can tell," Maggie replied in an equally quiet tone. "I noticed she didn't get her cuffs yet. Thought she might want them."

"I tied her arms. Apparently that was good enough tonight."

Maggie padded closer, a wry grin dancing on her face. "I'm surprised she could make do."

"Well, you know, she's kinda wore out."

Laine waited to see if that would provoke a reaction from Maggie. It didn't seem to have much of an obvious effect.

Maggie sat down gently on the edge of the bed. Cat lay naked and beautiful between them. She'd fallen asleep on the covers, and Laine hadn't had the heart to disturb her for the sake of arranging the blankets properly.

Maggie brushed back some of Cat's hair that Laine had been playing with. Her eyes were full of some kind of emotion, but Laine couldn't quite tell which. It was a good one, he thought. He hoped.

"You had sex, then," Maggie said. It wasn't quite a question.

"We did," Laine admitted.

"First time?"

"Us? Or her?"

"You two. Together."

"Then yes."

Maggie nodded. "I take it she's even more smitten with you now." Again, not really a question.

"You'd have to ask her," Laine said, just a little evasive in his answer.

"I just might."

Maggie sat there a little while longer, mostly just watching Cat sleep. Laine didn't mind, that was basically all he'd been doing after all. There was definitely something going on in Maggie's head though.

"Do you want to talk?" he asked. "I can maybe slip out without waking her."

Maggie abruptly shook her head and stood up. "No. No, I should probably head to bed soon too."

"Ok." Laine bit his lip a moment, toying with a bit of an odd offer. Since he had their parents' old bed, there was enough room for three, if need be. "You could sleep with us, if you wanted."

Maggie gave him a wry, somewhat disbelieving look. She also seemed amused rather than annoyed or melancholy, so Laine was fine with whatever mild scorn he took.Probably not a great idea," she said. "That could get... confusing."

Laine didn't fully understand what she meant by that. Ordinary life these days was pretty confusing all on its own.

"You might be right," he said, wholly unwilling to bring it to an argument. "It's a real offer though, if you change your mind."

Maggie flipped her hair and gave Laine a strange smile. "Thanks, but still no. See you in the morning."

"Yeah, ok. Night."

She left, helpfully hitting the lights and closing the door on her way out. Laine was alone with Cat once again.

He still wasn't quite ready for sleep. And now his mind was busy wondering whether Maggie was jealous. That was a strange thought all its own, though not nearly as strange as it would have been once upon a time.

Laine hoped it wasn't anything like that, but there wasn't much he could do about it either way.

****

Catria came home from school the next day to find Maggie sulking on the couch. It looked like she had Downton Abbey playing, but Catria wasn't sure she was paying much attention. It didn't look good.

"Hey," Catria said, starting out upbeat and chipper just in case she was reading her sister wrong. "What's going on?"

Maggie shrugged. "Not much, really."

"Cool, cool."

Catria pulled her socks off even as she neared the sofa. By the time she perched on the arm of the couch, she was down to shirt and panties; her casual house wear. Maggie was hogging the actual sitting space on the couch by lying across it, slightly curled in on herself.

"Get off work early?" Catria asked.

"Didn't go. Took a sick day."

"Oh." Catria didn't much care for that answer. "Well are you feeling better now?" she asked in a final, insane bid for a happy ending.

Maggie sighed and gave her a look.

"Yeah, didn't think so," Catria said.

She got down on the floor, sitting with her back to the couch. She rested the back of her head on the cushion just in front of Maggie's chest. With great patience, she waited until Maggie finally gave in and started playing with her hair.

"You're not a puppy, you know," Maggie said with a promising hint of humour.

"I know. I'm a Cat."

"Very funny. I mean you shouldn't just sit in front of me and expect to be petted."

"It's got a remarkably decent success rate."

"That's entirely not the point."

"If you say so."

Despite Maggie's apparent exasperation, she kept stroking and playing with Catria's hair. Catria sat still and pretty while being caressed.

"Do you want to tell me what's wrong?" Catria asked.

"I really don't know," Maggie said.

"Oh. So it is about me. I thought it might be."

"There could be other reasons why I don't want to tell you."

"Yeah, but it's not that you don't want to tell me. You said you don't know if you wanted to."

Maggie was quiet a moment. Her fingers dropped lower and tickled Catria's neck. "You're remarkably perceptive sometimes."

"Thanks."

"But I genuinely don't know if I want to tell you. Or anyone. I haven't really worked out how I feel, let alone how to explain it."

Catria nodded. "Ok."

She was happy enough to sit there and get head scratchies. She was pretty sure she was helping Maggie, functioning as a therapy pet of sorts.

She didn't have much idea what was going on in the show Maggie was watching. She only half watched, and mostly just daydreamed away.

They were onto the next episode before Maggie spoke again.

"I think I got jealous," Maggie said.

"Of Laine?"

"Of you and him, yes."

Catria frowned. "But you don't need to be. We're not--"

"I'm perfectly aware I don't need to be, thanks. That's part of what bothers me, and why it's so hard to explain."

"Oh."

"I like that you're happy," Maggie said softly. "And I like that Laine makes you happy. I guess maybe it bothers me that I can't make you as happy as he can."

Catria decided she probably couldn't carry on the discussion while facing away. She got to her knees and turned around, then sat back on her heels. Maggie's expression stayed more or less neutral, but with a hint of sadness to it.

"That's not true," Catria said.

"Isn't it?"

"No!"

"So you wouldn't rather do sexy stuff with him?"

Catria frowned. "That's a whole different thing. I like boys. Laine's a boy. It's not fair turning that into him making me happier, or whatever."

Maggie sighed. "I know. I'm really not explaining myself very well."

She went quiet again. Catria really didn't want to wait for another attempted explanation. That wasn't good enough this time.

Catria lifted herself higher while remaining on her knees. She prodded her sister. "Make some room."

"What?"

"Lemme in."

"It's not that big a couch."

"Good thing I'm only little."

With some determination and a lack of fear of coziness, Catria managed to squeeze onto the couch without Maggie moving too much. She lay parallel to her sister, with her backside pressed snugly up against Maggie's front. She pulled Maggie's arm around her as per classic spooning etiquette just for good measure.

"So what's this going to accomplish?" Maggie asked.

"Nothing. We're cuddling. That's all."

"Why?"

"Same reason as any other time. 'Cause I like it."

"You think this is gonna cheer me up, don't you?"

Catria shrugged and declined to answer, though in fact that was exactly what she thought.

"You're lucky you're the baby, you know that?" Maggie said. "Your whole thing wouldn't work otherwise."

"My whole thing?"

"Yeah. Your cutesy helpless thing. Your puppy act."

Maggie's hand had been dangling over Catria's midriff. It gradually slid over until it cupped a palmful of tit instead.

Catria grinned to herself as she was gently felt up by her sister. "You think I'm cute and helpless?"

"That's not what I said. You act that way, is all. And it works because you're our little sister."

"I dunno. I think Laine might like it even if I wasn't his sister at all."

"Well of course he would. He's a boy." Maggie pinched Catria's nipple. "You being all sexy and adorable and desperately in need of his big strong manliness would win him over sooner or later regardless of who you were."

Catria giggled as Maggie found a sensitive spot under her breasts. "Now you're just being silly."

"I wish I were."

"Well, I mean, you don't even like girls anymore than I do, right? How come you're worrying about what I think about Laine or what he thinks about me?"

"Do you realize how weird that sounds? Considering that your tongue has been firmly entrenched in my vagina."

"Well yeah, but... I mean...." Catria squirmed, which mostly just made her and Maggie's bodies rub together. "I like doing stuff with you. Even if you're a girl."

"Yeah. Exactly."

Catria considered. "So are you saying that it's not that you're jealous, but more like... you're maybe just confused? Sexually speaking?"

"Maybe. Partly. Are you not?"

"Oh I totally am. But as long as I'm having fun, it's hard to worry about it too much."

"Uh huh." Maggie was now fully caressing and stroking Catria's boobs. "So is that what I should do? Just have fun and not worry about it?"

"I dunno. Maybe."

"How very helpful."

Catria didn't feel the need to argue against her sister's sarcastically made point. Given the way Maggie was feeling her up, and actually starting to grind on her a little, she knew she really was being helpful. No one could stay truly melancholy when they had a nice pair of tits to play with.

Maggie fondled Catria's boobies and occasionally rubbed her tummy. Her fingers slipped under her sister's shirt more than once, and she gradually tugged the garment higher and higher.

Eventually Catria's shirt was pulled up pretty securely over her breasts, to the point where she might as well have been topless. She hadn't given any outward indication that she even noticed, though she was perfectly thrilled to be touched and exposed, as per usual.

Another episode of Downton Abbey passed with Catria only catching bits and pieces. She lay languid and still, very nearly falling asleep, while being constantly held and stroked and fondled by her sister.

It amused her to imagine herself as a toy; a stress reliever of sorts. An inanimate object to be posed and squeezed as much as one desired.

Catria's pussy tingled as her little fantasy went further. In her head, Maggie played with her a while longer, only to eventually grow tired. Catria was left immobile, all by herself, until Laine found her, whereupon he threw her over the arm of the couch and fucked her limp body like that was all she was for.

Good lord she had issues. Sexy, hedonistic issues.

She bit her lip and rolled her eyes back in silent ecstasy when Maggie finally made it to her pussy. Her big sister's fingers slid easily into her damp panties and made delicious contact with her wet little cunt.

Maggie was still in no real hurry. Her middle finger lethargically traced Catria's slit up and down, then she toyed with the clitoral region, but she didn't really focus on actually getting her sister off, or indeed put much energy into it.

"I love this, you know," Catria said quietly.

"Love's a strong word," Maggie said. "I'm not even really doing much. Are you sure you don't just mean that you enjoy this?"

"No, I know what I mean. I think I might actually like it better when you're just toying with me."

Maggie snorted. "Is this you trying to cheer me up still?"

"Partly. But it's true. I mean, my sister, who's not even a lesbian or anything, will happily cuddle and finger me just for something to do. I genuinely love everything about it."

Maggie kissed Catria's shoulder. Two of her fingers pressed Catria's pussy, and slowly sank into her slick hole. "You're a slutty little thing, aren't you?"

Small thrills ran up Catria's spine. "Mmhm."

"You get off on goddamn everything."

"Well... not everything."

"I could probably tie you up naked in the front yard all day where everyone could see, and you'd still enjoy it."

Catria's eyes widened involuntarily. That was a far more daring image than even she tended to think about. But no less exquisite for its origin.

"Do you think about doing that?" Catria asked breathlessly.

"No, Cat. That was an example. Obviously I'm not going to do that."

"Oh." Probably for the best, but still disappointing.

"Such a slutty little sister."

Maggie thrust her fingers in deep. Catria let out a series of small, utterly contented moans as she was properly finger-fucked at last.

"Yesss," Catria hissed.

After so much teasing, she was more ready for the assault on her pussy. Maggie's fingers moved hard and fast, sending shocks of delicious pleasure through Catria's horny body.

Catria rolled her hips uncontrollably in response to her sister's stimulus. She found that if she wiggled just right, she could grind her clit on Maggie's palm. It was a moving, inconsistent target, but when everything lined up it was heavenly.

She mewled and writhed and enjoyed every second of her sisterly fingering. She was eventually brought to a lovely orgasm by Maggie's hand buried between her legs.

They cuddled a little while after. Maggie offered her pussy-soaked fingers for Catria to suck on, which she obliged without hesitation. Maggie nuzzled at her neck and planted the occasional soft kiss on her shoulder as well.

"Do you want me to lick your pussy now?" Catria asked.

Maggie chuckled softly. "You know, despite everything, it's still weird hearing you say things like that sometimes."

"Is that a yes?"

"Actually," Maggie said, interspersing her words with another kiss on Catria's shoulder, "I think I'd like you to go get your cuffs--"

"Ok!"

"I wasn't finished. There's something in my room that I want you to bring back with you too."

"Uh, ok. What is it?"

"You'll see it. I had it out on my bed earlier. Don't know why, really. I wasn't in the mood until now."

"Sure, sure. But what is it?"

"Cat, my darling, I promise you'll know as soon as you walk in. I don't want to spoil the surprise."

"Ooh. Another present for me?"

"Of a sort. Something I picked up when Laine and I went shopping."

Catria was truly excited now. Her butt plug had been quite a fun new toy, and now there was another one! And she was pretty sure neither of them was even the main surprise, assuming that was something her siblings wanted to give her together. Though that was mostly an educated guess.

She bounced to her feet and skipped off to find out what fun thing Maggie had bought.

"Oh, and you don't need to bother with clothes when you come back," Maggie called after her.

Catria was even more excited now. She kind of wished Maggie had given her a command to return naked rather than a thinly veiled suggestion, but it was still a nice thought.

She happily discarded her shirt and panties in her room, then snatched up her handcuffs. She twirled them in her hands as she padded naked over to Maggie's room, anticipation building delightfully in her chest.

Maggie had been right, of course. Catria knew exactly what she'd been sent for practically as soon as she opened the door.

There, sitting on Maggie's bed in plain sight, was a dildo. And not just any old dildo either; it was attached to a harness. Maggie had bought an honest to goodness strapon. Holy fucking shit.

Catria grinned to herself as she pranced back down the hallway, cuffs in one hand, strapon in the other. Maggie must have been feeling much better if she wanted to break in a fun new toy like that.

Little fits of jealousy and insecurity were probably to be expected, in hindsight. Hopefully Maggie wouldn't go down that road again, but Catria made a mental note to try and watch out for such things in the future. She'd much rather be spending her time trying out new sex toys than tending to hurt feelings. But then, who wouldn't?

Catria felt a sudden pang of shyness as she returned to the living room. Not enough to slow her down much, but she did flush and hesitate just a little as she walked the last few steps. She wasn't quite sure whether to hand over the handcuffs or the strapon first, nor was she certain about what was going to happen afterward.

"That was quick," Maggie said. She was down to her shirt and panties, much as Catria had been previously. She was, indeed, looking much more confident and self-assured than an hour or two ago.

"Well it wasn't that far away," Catria mumbled. She bit her lip, then got close enough to hand over the strapon.

Maggie gave an odd, crooked smile. "Thanks." She began strapping herself in. "You know, I wasn't totally sure this was going to be a good purchase when I bought it. But after last night, I guess it's probably fine, huh?"

Catria shifted her weight awkwardly. "Is that why you were upset? 'Cause I had sex with Laine?"

"That was the catalyst, yes. But I don't think I actually have a problem with the sex itself. I mean, I knew it was coming sooner or later."

"Are we gonna have sex now?"

Maggie tilted her head, her lips still quirked in an enigmatic grin. "You sound so unsure about it. We don't have to do anything at all if you don't want to."

"No, no. It's not that," Catria said quickly. "I just wasn't sure what was happening."

"Well, my dear, you're naked, and I've got a dildo jutting out from my pelvis. How many possibilities do you think there are?"

Catria flushed. "You don't need to pick on me about it."

Maggie snaked a hand around her sister's waist and pulled her in for a soft kiss. "And here I thought you liked that sort of thing," she whispered.

"Well... I mean...."

Maggie took Catria's cuffs from her unresisting hands. Catria obediently turned around and presented her wrists for binding. As soon as she was all locked in, Maggie sprawled herself along the length of the couch, dildo sticking obscenely up toward the ceiling.

"C'mere," Maggie said, patting her lap.

It took Catria a few seconds to realize she was meant to climb on top of her sister somehow. Without her hands free, it wasn't an easy maneuver. She stepped next to the couch, then hesitated, unsure of where to put her feet.

"That's it," Maggie said. "There's a good girl."

Catria's face felt so warm. Maggie was doing it on purpose, she realized. Giving her a tricky task while she was all naked and helpless.

Her embarrassment and uncertainty transitioned from merely awkward to intriguingly arousing. Maggie's eyes were fixed on her, sweeping and studying. Not the slightest bit of physical help was offered. She was being teased and toyed with, just the way she craved.

Catria managed to get one of her legs across Maggie's body, then carefully shifted across until she could bring her other leg up and straddle her sister while kneeling. Maggie traced light fingers up her thigh and even tickled her pussy, but nothing more than that.

With a bit more shifting and shuffling, Catria positioned herself directly over Maggie's protruding strapon. She was so excited now that her heart was pounding and she imagined she could feel her pussy dripping. And the way Maggie just kept staring....

It took a few tries to actually land properly on the dildo. It kept sliding off instead of going in, which only added to Catria's embarrassment, and by extension her arousal.

It felt so good once she connected and began sliding down Maggie's dildo. She sank lower and deeper, bouncing a little as necessary on the way. Her eyes were half-lidded with pleasure by the time she had taken the dildo all the way to the base. She was barely even cognizant of her sister at that point.

Catria rested for a moment, enjoying the feeling of being filled up. She shifted her knees to get a slightly better angle, then started grinding back and forth while also bouncing a little. She worked Maggie's fake cock with increasing confidence while her sister lay back and did basically nothing.

"You enjoying that?" Maggie asked totally unnecessarily.

Catria nodded. "Mmhm."

"Good."

Maggie very deliberately turned her head and resumed her paused show. She gave every appearance of ignoring her little sister bouncing away on her lap.

Catria felt about as slutty and ashamed and turned on as she ever had. She knew what Maggie was doing, it wasn't particularly subtle, and yet it still had the intended effect. She was made to feel as though Maggie didn't care what was happening, and that it was her own uncontrollable urges that led to her essentially masturbating atop her sister's body.

What a hopeless little slut she was.

She could have stopped at any time. She could have refused to participate on the grounds that Maggie wasn't even watching. But she had no intention of doing that.

Catria rode Maggie with fresh determination. She thought that maybe enough of an effort would get her sister's attention. She writhed and wiggled her naked little body, doing extremely pleasant things to her own pussy in the process, but Maggie was steadfast.

It was a rather pitiful and insignificant feeling to be doing her best and getting nothing back. She knew Maggie couldn't actually feel very much of it, and indeed was being deliberately obtuse, but she also fed those internal emotions. She fanned her instinctive urge to be acknowledged, getting herself all worked up over something she knew to be a purposeful ploy.

They must have made quite the sight. Catria was naked and horny and rocking like crazy, while Maggie chilled beneath her without giving away any hint that anything at all was happening.

Catria brought herself to orgasm by her own efforts and imagination. She bucked a little more wildly and mewled in uncontrolled lust.

That was the first time Maggie acknowledged her since she'd started. Catria flushed hot and red when she realized her sister was watching her cum. Maggie's faint smirk made it all the worse, and all the more deliciously sensual. She was being blatantly toyed with and manipulated, and she was playing along just as hard she could.

"Slower, little one," Maggie said with a softly condescending tone. "You don't want to wear yourself out."

"Ok," Catria said faintly.

She slowed her pace, rocking gentle and smooth. Maggie played with her tits for a bit, then turned back to the tv and ignored her once more.

That was how they spent the next little while. Maggie treating Catria with a general air of indifference that totally got her off, and Catria riding her sister while longing for some attention, despite being thoroughly turned on by the lack of it.

Even Laine's arrival didn't stop them. Catria slowed down, then stopped as her brother came in the front door. Maggie, however, gently slapped her thigh a few times.

"Did I tell you to stop?" Maggie asked.

Catria bit her lip, then shook her head.

"Then why did you?"

Catria squirmed and glanced toward the doorway, expecting Laine to turn up any moment, but then resumed rocking. Every grind of the dildo inside her was magnified all the more by the anticipation of her brother appearing in the doorway.

As expected, Laine stepped into the room moments later. He stopped short at the sight before him.

"Hey," Maggie said in totally normal voice. "How was work?"

"It was alright." Laine crossed his arms and leaned against the door frame. "Seems like you two have been having a good time."

Catria felt the heat in her cheeks. She didn't know where to look. She didn't want to meet either of her siblings' eyes, but she was also desperate to gauge what they were thinking.

She peeked at Laine frequently, since she already had a decent idea what was going on with Maggie. Laine was curious and at least kind of interested, but he also hadn't approached yet.

And there she was, grinding away like a horny, naked sister-slut.

She felt Laine's eyes on her even when she wasn't looking. The longer he stared, the more intense the anxious feeling in her tummy got, and the stronger the urge to pleasure herself became. It was all she could do to maintain her calm, casual rhythm and not start pounding her sister's lap.

"You can't have Cat right now," Maggie said to Laine. "We're busy."

"Yeah, don't worry. I figured that out," Laine said. "Do you have any plans for supper?"

Maggie ran a fingernail up the centre of Catria's tummy and chest, right between her breasts. "Somehow I didn't get around to it."

"What a surprise."

They were so nonchalant about the whole thing. Catria was going a bit crazy about how casually her brother and sister discussed what to eat while she was acting the slutty little nymph in their midst. She was so turned on she actually ached.

Catria came again just before Laine left. The conversation died abruptly as both Laine and Maggie watched her twitch and convulse uncontrollably.

Laine smirked and left the room without saying anything else.

"You are a shameless little exhibitionist, aren't you?" Maggie said.

Catria slowly shook her head. "No. It wouldn't be any fun without the shame."

Maggie laughed, clear and unrestrained. She pulled Catria in for a kiss, which nearly toppled her delicate balance. "God I love you."

Catria didn't know how to respond. She stayed quiet and red, and shifted her weight to get back to ideal position. She resumed rocking her hips like there'd been no interruption at all.

Supper was a welcome break. Catria was still horny and ready to go, but her legs were tired and threatening to give out on her. She was content to stop, at least for a while.
