@4 - Taboo Incest sex stories

Her siblings didn't uncuff her to eat. Instead, they sat her in the middle of the couch, sandwiched between them, and took turns feeding her. It was kind of a babying experience, particularly when a bit of food missed the mark and she had to be wiped up.

Maggie kept Catria claimed the rest of the evening, and ended up taking her to bed as well. Catria was pretty worn out by bedtime, but she wasn't really made to exert herself anymore.

Somewhat surprisingly, once Catria lay down on Maggie's bed, her legs were gently pried open and Maggie settled down between them. Maggie kissed her pussy, then gave it a long lick before pausing to consider.

"You don't have to do that," Catria said softly, wanting to forestall any sense of obligation her sister might feel to do something she didn't really want to.

"I know," Maggie said. "I want to."

"Do you?"

Maggie kissed the inside of Catria's thigh. "I really do."

Catria nodded. "Ok."

Unlike before, there were no games being played, nor any real internal conflict on display. Maggie was a little hesitant and unsure at first, but she got into it. She licked Catria's pussy slowly, tenderly, and with all the sisterly love she possessed.

Catria was brought to the slowest, most luxurious orgasm of her life. It was so different from what she was used to. It was somehow unexciting in the best way possible. Nothing but constant, gentle licks over and over.

Catria was practically falling asleep once she came. She smiled wide and lazy at Maggie, and accepted a kiss tinged with her own flavour.

The sisters curled up naked together and drifted blissfully off to sleep.

Part Five: Revenge of the Sis

****

Laine was pretty used to coming home to a casually misclothed Cat. It barely even registered as odd anymore, though he still very much appreciated it when he took the time to look.

He was not, however, used to finding her sitting out on the back step with no bottoms, lazily fingering herself as though it was the most private place in the world.

"What are you, like, trying to seduce the neighbours now?" Laine asked after he'd parked and exited his car.

Cat smiled. "Nope. Don't worry, no one's watching."

"How could you possibly know that?"

"Well... I don't, I s'pose. But someone would have to be awfully nosy to get a good look at me."

"They'd really just have to peek over the fence."

Cat shrugged. "And so far, no one has."

"That's not really a good argument."

"Ok, so assuming someone sees. So what?"

"What?"

"Like, you know, what're they gonna do? Call the police because someone's masturbating on their own property?"

Laine shook his head wearily. "You know what, I can't even argue this right now."

He patted Cat's head and stepped past her to go inside. She leapt up and tagged right along after him.

"I try to be good, you know," Cat said.

"I don't know that I believe that, but sure."

"I do. I just get bored. There's nothing to do when you and Mags are both still at work."

Laine arched an eyebrow. "I think there's plenty to do if you really wanted to. Like, you know, hanging out with your friends."

"I just did that yesterday." Cat hesitated. "Or maybe the day before."

"Homework."

"Well...."

"Housework. Netflix. Reading a book. Mowing the lawn. Playing with yourself indoors like a normal person. Making supper."

"Ok, ok," Cat said, squirming under the barrage of suggestions. "So maybe I was horny and hoping someone'd be home soon."

"Ah. Yes. I thought it might be something more like that."

"And it worked! You're home now."

Laine stopped and studied his sister. She was practically bouncing with excitement.

"What did you do?" he asked.

"Hm?"

"I mean, you're always horny, but not usually like this. Not to the point of playing with yourself outside for the extra thrill."

Cat clasped her hands behind her back and wiggled a little in what might have been an innocent pose, if not for her total below-the-waist nudity. Bare pussy really limited a good-little-girl act's effectiveness.

"So..." Cat said, "I mighta, like, wore my butt plug to school today."

Laine's cock twitched. "Did you indeed?"

"Mmhm. I had to take it out at lunch. It got kinda uncomfortable after a while." Cat flushed. "And a little messy."

"That'll happen."

"But I'm all showered and clean now...."

Laine folded his arms and glared with mock severity. "So all this time you were waiting, you were just hoping your lack of pants and your story about wearing your plug to school were gonna make me want to fuck around when I got home?"

"Well... yeah. Basically." Cat beamed angelic and hopeful. "Did it work?"

"Of course it did." Laine pulled her in and kissed her. His hand snuck around to her naked bum and gave it a firm squeeze.

Cat melted into his arms. She returned his kiss passionately while sticking her butt out for more groping.

"Wearing my plug was so fun," Cat said as she nuzzled Laine's neck. "I felt it every time I sat down, and I sometimes couldn't help just, like, grinding around in my seat."

"You didn't play with yourself at school, did you?"

"I might have." She put her mouth to his ear. "My panties were so wet by the time I took my plug out," she whispered. "I took them off for the rest of the day."

Laine scooped Cat up in his arms, unable to wait any longer. She squealed and kicked in delight at being carried off to his bedroom for naughty times.

Laine tried to take his clothes off once they got to his room. Cat helped, which made the process take quite a lot longer than it should have. They eventually fell into bed together in mutual states of near-nudity. Their few remaining clothes came off as they wriggled around kissing and fondling one another.

"You really are horny today," Laine said. "Even for you."

"I warned you," Cat said.

"Yeah, you did."

Cat giggled as Laine kissed a line down her neck to her breasts. He nuzzled and sucked on her tits, then carried on downward.

Her legs spread wide for him as he made it to her pussy. He licked her wet slit, tasting her arousal. His baby sister was unquestionably in need of some play time.

Cat mewled happily and ran her fingers through Laine's hair while he gave her little pussy some loving attention. His fingers penetrated her easily, and he licked and fingered her to a nice, quick orgasm.

Laine lifted his head, chin wet from her juices. She grinned back through half-lidded eyes, still very much ready for more.

"So," he said, "you've been playing with your butt lately."

"Well you don't need to say it quite like that," Cat said.

"Why not? You have been, haven't you?" Laine kissed her inner thigh. "You've been a naughty little sister, playing with your butt so much."

He got exactly the reaction he expected. Cat flushed and bit her lip, while simultaneously spreading her legs subtly wider. He was starting to get the hang of how her deviant side operated.

"I thought you'd like it," she murmured.

"I do. But I don't believe for a second that you don't. Not after you bragged about your school adventures today."

Laine grabbed Cat's hips and rolled her onto her front. She shrieked and offered a token protest, wriggling in his grasp as he spread her ass cheeks.

A sharp smack on the butt settled her down, and a few more followed just for good measure. Her hips lifted a little more with each slap of his hand on her ass. She got her knees under her, but didn't move her top half. Laine gave her a final spank, then just sat and admired her wantonly raised bottom.

Laine had gotten better at using discarded shirts to tie Cat's arms back. Her cuffs weren't always handy, and besides the crude bondage had a certain charm all its own. It was less formal and effective as a restraint, but she loved it all the same.

Cat was getting all wiggly again by the time her arms were secured. She was stuck in her face down, ass up position, and clearly ready for some more fun.

Her butthole was right there, laid bare before Laine. He leaned down toward it and dragged his tongue along the cleft between her ass cheeks. Given her recent shower, it tasted mostly just like skin, with maybe just a hint of a fruity soap of some kind.

Cat giggled as he kept licking. "That's my ass, Laine."

"Yes, I know."

"You shouldn't lick it."

"Oh? And what should I do with it, exactly?"

That shut her up. A quick glance at her face revealed that she almost certainly had some ideas, but was reluctant to actually vocalize them.

Laine pressed a finger to Cat's tight hole. She gasped softly, but didn't protest.

"Would you rather I put a finger in?" Laine asked, gently circling her butthole.

"I don't know," she said in a soft whine. "Maybe."

"Maybe?"

Laine pressed a bit harder and felt her asshole nearly give way, but not quite. He probably could have done it with just his spit lubricating her, but that was unnecessary when he had some of the real stuff to use.

He felt Cat's eyes on him as he got out of bed long enough to grab his bottle of lube. It wasn't clear whether she was merely anticipating what was to come, or whether his naked, erect form was just that tantalizing to her.

He knew for sure that he liked seeing her all naked and tied up and patiently waiting. There was a time he wouldn't have admitted any more than that his baby sister was pretty cute. Nowadays he couldn't even pretend not to think she was adorable, the right amount of slutty, and just the sexiest little thing he could ever hope to have in his bed.

"You're staring," Cat accused.

"I am."

Her face had gone red. "Why?"

"Because you're beautiful. And in another timeline, I never would have seen it."

Cat squirmed. "All you can see is my butt."

"I can see more than that." Laine knelt being her and kissed her bottom where it was still warm from her spanking. "Though I do like your butt."

Cat squirmed some more, but she was fighting a grin.

Laine smeared some lube around her butthole, massaging the tight opening. He poked his finger in and out a few times, gradually transitioning into a slow finger-fuck. She was still pretty tight, but more accommodating that he recalled. Her self-training seemed to be paying off at least a little.

Two fingers went in almost as easy as one. Cat moaned softly at being doubly finger-fucked.

"You know what I really want to do?" Laine said.

"No," Cat said faintly.

"Yes you do. You've been expecting it. Possibly trying to tempt me into it, for all I can tell."

"Well it's been forever since you played with my butt the first time. And you still weren't, like...."

"Fucking it?"

Cat was bright crimson. She went quiet, but still held her ass up in the air.

"All you had to do was ask," Laine said.

"Why would I?" she mumbled. "You're the one who wants it."

"Don't try that game with me. I know better."

Laine thrust his fingers harder. Cat definitely seemed ready for him, and goddamn was he ready for her. He'd been wanting to try out her sweet little ass, but the time had never seemed quite right. Now that she was doing her whole 'passively begging for it but pretending she didn't care' thing, it was happening.

"So maybe I've thought about it," Cat admitted.

"You don't say."

"And maybe it'd be nice to know what it feels like."

"So what you're saying," Laine said slowly, "is you'd like your big brother to fuck you in the ass."

Cat tensed and arched her back even higher. Her eyes closed for a second, then opened all the brighter and wilder. "Please big brother. Please fuck my ass."

Laine grinned broadly. "I can't believe you just said that."

"Shut uuup," she whined. "Don't be mean."

"I wouldn't dream of it."

A few more thrusts of his fingers, then Laine pulled out. He grabbed the lube and got his hard, impatient cock all nice and slippery.

Cat watched with barely contained anticipation. Her eyes bounced from Laine's cock up to his face, then back again. Her hips were getting all wiggly by the time he was ready.

Laine grabbed Cat's ass to steady her, and she managed to restrain herself. She inhaled sharply as he pressed his cock to her butthole, then gasped aloud as he pushed it in.

He went gentle and slow, but still his cock disappeared inside Cat much faster than expected. Her ass accepted the intrusion like they'd been doing it for years.

"You really have been practicing, haven't you?" Laine said.

"Mmhm." Cat rocked back against him, eyelids fluttering in response to her anal impalement. "I told you I was."

"I guess I didn't realize how serious you were about it."

He fucked her a little harder, which in turn made her push back more firmly. If anything, Cat seemed less worried about going too fast and getting hurt than he was. But then, she knew her limits better than he did. Particularly if she'd been playing with her butt even more than he'd guessed.

Laine didn't fully let himself go. As prepared as Cat may have been, she was still new to anal. He did, however, allow his senses to be lost in the moment, and the sheer, amazing pleasure.

It was kind of insane that he was actually fucking his baby sister's ass. It was tight and warm, and so deliciously naughty. Even better, she seemed to be loving it just as much as he was.

Cat's eager writhing and rocking was one of the best parts. She was impaling her own ass almost as energetically he was, and only seemed to get more into it the longer they went.

"Does this really not hurt at all?" Laine asked.

Cat thought about it a moment. "A little, I guess," she said breathily.

"We can slow down if--"

"No," she said in a firm tone. "Keep going."

It was a bemusing request, but Laine was happy to abide by it. His sister's ass was addicting and compelling, and he really didn't want to stop. Besides, everything about her demeanor and expression screamed that, pain or no, she was fully enjoying herself.

Time slipped away. Laine gradually lost track of anything except for how amazing Cat made him feel, and how much he liked the little mewling noises she made when he fucked her just right.

Eventually, inevitably, Laine came hard in Cat's butt. His cock pulsed and spewed hot cum deep inside her. She let out an animalistic whine and kept rocking well after he'd finished and gone still.

He had to pull out, much to his sister's disappointment. He lay down next to her and reached a hand out to stroke her hair.

Cat, full of hope, stayed put for a moment after, then gave in and rolled to her side, then scooted right up next to him. He wrapped his arm around her as she nestled into his embrace.

"You came in my butt," she said.

Laine couldn't help smiling. "Yeah. I did."

"It was weird."

"Good weird?"

"Mmhm. Very nice. Weird, but in a sexy way."

"I'll have to do it again then."

"Yes," said Cat seriously. "You will."

Laine idly rubbed her arm up and down from elbow to shoulder. He was pretty happy that she wanted to do more butt stuff, and despite his post-orgasmic state, was kind of turned on by the idea. Naked cuddles probably contributed.

"Your graduation's coming up," he said.

"That's true."

"Excited?"

Cat thought about it. "Yes and no. I'm kind of excited, but kind of nervous too. And I'm not sure I'm really happy about not going to school anymore."

"Really? I didn't think you liked it that much."

"I didn't. But, like, all the pressure's off now. I made it through grade twelve." Cat shrugged. "So I kinda wouldn't mind still going."

"That would be what post-secondary education is for."

"Yeah, but then there's pressure again. Plus my friends are all going to different schools, and I've partly just been enjoying school more lately because I haven't been seeing them as much."

Laine kissed her shoulder. "You've been spending too much time with me and Mags. You're allowed to hang out with your friends as much as you want. In fact, you should."

"Yeah, I guess."

Laine didn't know exactly what his sister was thinking. Her face was less readable than usual. He was quite certain, however, that she would never entertain the idea of going away to college, even if it wasn't too late for that this year.

"We could see about signing you up for the local college," Laine said. "You must know some people going there."

"Maybe."

"Or not. Just a thought."Cat giggled softly. "Don't worry. I'll be fine. I'll have more free time to do friend-type stuff. I'd be so bored waiting around for you and Mags to get home every day."

"You really would."

They both went quiet. Laine could feel his sister's soft heartbeat. He felt so close to her, and not just physically. He could have lain there in silence for hours, just being with her.

"You're coming to my graduation, right?" Cat said.

"Of course I am," Laine said. "You didn't really think I'd miss it, did you?"

"I wasn't sure. That's all. I know they're kind of boring."

"They are," Laine confirmed. "I know mine was. But Mags had some good ideas to make it more interesting."

Cat lifted her head and gave him a funny look. "What kind of ideas?"

"Oh, you know. Stuff like making you go naked under that robe thing you'll be wearing."

"What?"

"And then she was gonna recruit some of your friends, so that just before you go on stage they can pull your robe off and you'll have to go up totally naked."

Cat squeaked and shook her head. "You're making that up!"

"Of course I'm making that up. Can you even imagine? You'd get in such trouble."

"Yeah. Trouble."

Cat relaxed back against Laine. Her heart was sped up from before, and it only slowly returned to a becalmed state. Even for a while afterward, Laine could see the wheels turning.

"You're thinking about actually doing it, aren't you?" he said.

"No."

"Ok, let me rephrase. You're imagining me and Mags making you do it."

She buried her head against him. "Maybe," she said in a muffled voice.

"My god, Cat. I don't know what to do with you sometimes."

Cat rolled away and struggled up to her knees. She shook her head tactically to get her hair back in some kind of order. "You're the one who started it. I never had any plans for being naughty at graduation."

"That's a fair point, actually." Laine patted her thigh. "But I promise, we're not gonna make you go up on stage naked. No matter how much you beg."

"I wouldn't even," Cat mumbled. "That'd be too many people. And none of 'em would mean anything like what you and Maggie do."

Laine smiled and sat up. He kissed his adorable, slightly flushed little sister. His hand stayed on her cheek a moment, then trailed gently away. "Guess it's settled then."

Cat nodded. She looked at him and bit her lip. "Could you, maybe, lie back down?"

"Sure I could. Why, though?"

Laine lay back without waiting for an answer. He should have been able to guess anyway.

Cat carefully shifted her weight and swung a leg across him without falling over. It was pretty obvious what she was after once she was straddling his waist, aroused little pussy closing in on his cock.

He'd been half hard again anyway after that stupid fantasy he'd thrown out on the spur of the moment. It actually wasn't so far from reality to imagine Cat up on stage, totally nude and insanely horny.

Other than the stage part, he had the rest of that descriptor directly before him. Cat lowered herself to grind awkwardly on his cock, coaxing it back to full stiffness with her warm, wet slit.

"Do you want your hands untied?" Laine asked.

"Why would I?"

"You know, to balance easier."

Cat gave a small, lopsided grin. "You still don't quite get it, do you?"

Laine snorted. "I will freely admit that I may never totally get it."

Cat scooted forward a tiny bit more, then lowered her butt. She had to adjust her position a few times, and even once she had her asshole lined up, she couldn't quite get Laine's erection to actually penetrate her. It kept sliding away and up her butt crack.

"Want some help?" Laine asked just a tad smugly.

Cat had gone her typical shade of light red, and wouldn't quite meet his eyes. "Yes please."

With Laine's cock held steady, Cat was able to sink down onto it for more successfully. Her eyes rolled back as her butthole stretched and gradually swallowed his length.

She took a short break once she'd taken his whole length. She sat astride him, ass all filled up with brother-cock.

Her hips rocked back and forth in small, slow motions. Her breathing was already coming ragged.

"If you actually were going to make me graduate naked," Cat said, "how would you do it?"

Ah. So that was what she was thinking about. "Well, as I say, you'd already be naked under your robes."

Cat nodded like that part was a given. "Sure."

"And hell, probably we'd have your butt plug in underneath too."

Another nod.

"And we'd have to talk to a couple of your friends, get them to stand near you and wait until it's almost your turn to go up."

Cat's eyes went half closed, and she bit her lip. Her movements were getting bigger, more up and down than back and forth.

"They'd have to strip you quick, not give anyone a chance to react," Laine continued, kind of getting into the scenario as he described it. It was pretty hot, if totally unfeasible. "Get you all sexy and naked, and probably throw your cuffs on too."

Cat whimpered softly and closed her eyes all the way.

"You'd be up on stage in front of everyone," Laine said, his voice dropping slightly. "Naked, alone, handcuffed. Everyone from school, all your classes, all watching. And their parents, and your teachers."

She let out a full moan while practically bouncing on him.

"And you'd have to take the diploma with your mouth, like a dog, 'cause your hands are stuck behind your back." Laine smiled at the totally wanton way Cat was impaling herself. "I can only imagine the pictures people would be taking."

Cat whined and fucked ever harder, then her movements went kind of jerky and her ass tightened around his cock.

"Did you just cum?" Laine asked.

She nodded shyly.

"Huh. And I didn't even get to the part where Mags and I take turns fucking you on stage."

Cat actually cracked up at that point. She giggled uncontrollably for a bit, still bouncing on her brother's cock all the while.

It was a calmer, gentler fuck now that Cat had got some of the energy out of her system. Laine played with her tits or fingered her pussy, or sometimes just ran his hands over her lithe, naked body. He only occasionally added another little snippet of their school scenario, but he got a fun reaction every time.

Cat's next orgasm took a lot longer. Neither of them were in a hurry for it, and it only came after a slow, luxurious anal fuck session, interspersed with some more frantic moments when she got a little too horny.

Laine came shortly after, dumping a second load of cum in his sister's tight little ass. She seemed quite happy with it, and snuggled up with him again until hunger finally drove them out to seek supper.

****

Graduation day rolled around. Catria's nervousness and anticipation of the event had shifted from perfectly normal considerations to mostly sexual ones.

That story Laine had made up really stuck with her in the lead up to crossing the stage. While waiting for her turn, she couldn't help wondering if something naughty was planned.

Of course her friends weren't in on some scheme to strip her right before walking out in front of everyone. Of course they weren't. They were just hanging out, waiting, whispering and giggling the same as everyone else. Totally normal. Definitely not planning to tear her clothes off. Not even a little.

It was actually a bit of a let down for Catria when she got up, accepted her diploma, and walked off again with very little ado. Sure she didn't actually want to be naked in front of all those people, all her classmates, all their parents and teachers. Sure Laine and Maggie would never actually go that far. But still, it was anti-climactic.

Almost as soon as she got off stage, her siblings rushed over to her and started hustling her toward an exit off to the side and out of most people's direct line of view. It was the door everyone else who wanted to sneak out without being noticed was using, as per tradition.

"Ok, ok, I'm coming," Catria said. "If you wanted to leave that badly, you didn't have to come in the first place."

"Nonsense," said Maggie. "We wouldn't have missed it."

"So proud of you," Laine agreed, sneaking a kiss on her cheek.

"Thanks," Catria said, blushing slightly from the kiss and wondering if anyone had seen it. "So then why the rush?"

"Because, dear sister, the rest of the school is empty right now," Maggie said.

"Well yeah," Catria said. "Everyone's in here."

"Precisely," Maggie said.

Catria followed along, bemused but compliant as ever. There was clearly some kind of plan afoot. She wasn't quite sure what to expect just yet.

Laine got close as they made their way down the empty corridors. "Are you naked under that robe?"

Catria bit her lip, then shook her head. She'd definitely considered it, but the logistics just weren't there. Plus, neither he or Maggie had actually told her to do it, and she wasn't nearly so brave on her own initiative. "No. Sorry."

His hand cupped her butt. "Don't worry. We can fix that."

Her heart pounded faster as they kept walking. The sounds of the graduation ceremony had faded, and it was becoming more and more like they were the only three in the whole building. An entire school all to themselves. This was getting interesting.

They were pretty well at the far end of the building before Maggie picked a room basically at random, for all Catria could tell. The selected classroom was deserted, as expected.

"This looks good," Maggie said as she flicked on the lights.

"Good for what," Catria asked a little breathlessly. She had a pretty good suspicion already, but she needed to hear it.

"For you to take your clothes off," Maggie said, confirming Catria's assumption.

"Right here?" Catria squeaked.

"Not enough people around?" Laine asked. "See, Mags, I told you we should have done it back at the ceremony."

Maggie rolled her eyes. "Oh hush, you." She turned more firmly to Catria. "I don't see any stripping happening."

Catria's fingers trembled as she removed her gown, then her regular clothes underneath. She kept glancing at the doorway, certain that they couldn't get away with this. She was so used to the school being filled with students and teachers, with nary an empty room, let alone a whole wing.

Neither Laine or Maggie made any attempt to speed her along or help in the process. They just watched as their baby sister stripped totally naked in the school she'd only just graduated from.

Goddamn she loved them.

Having finished removing her clothes, Catria stood awkward and flushed while being thoroughly eyed by her siblings. She was excited and nervous, and so very eager to see what came next. Her arousal had lessened her fear of being caught, though it was still very much present in her mind.

Maggie had brought a large purse with her. To Catria's delight, and not particularly surprising her, her sister pulled her handcuffs out and dangled them enticingly.

Catria stood obedient and nude, hands behind her back. She knew she was risking being caught not only naked, but now cuffed as well. It was a scary thought, and not something that could be easily explained away. Nudity alone might possibly be dismissed as some kind of juvenile lark. Light bondage, not so much.

That was the thrill, of course. She hadn't felt sensual danger like this since her brother and sister had each accepted her kinks and her rather unfamilial love. Her little pussy was so wet she was actually dripping down her leg.

Laine took the cuffs and locked Catria in. He swiped a finger up her thigh and sucked it into his mouth. She bit her lip, meeting his gaze with shy but eager eyes.

Maggie, meanwhile, had been stuffing her purse with Catria's clothes. "Ready?" she asked.

"Yep," said Laine.

"Um... ready for what?" Catria asked.

Her siblings grinned, then abruptly wheeled around and took off. Catria stared after them for a moment, suddenly alone, naked, and cuffed in the middle of school. She was left bereft of even the security of numbers she'd enjoyed up until then.

"Wait!" she yelled desperately, then cut herself off from shouting anything more since it could possibly attract other attention.

The only thing she could do was to run after Laine and Maggie. They weren't quite out of sight by the time she left the classroom, and clearly weren't actually trying to lose her, but they weren't making it an easy chase either.

Her gait was necessarily awkward with her hands restrained and her shoes in Maggie's purse. She couldn't go anywhere near her full speed, which let her siblings stay nicely ahead of her without really exerting themselves.

Every corner was another opportunity to be surprised by some other wanderer of the halls, or someone patrolling to keep out the trouble makers. Every empty classroom had the potential to be filled as she dashed by. She was so scared, and so unbelievably turned on.

Maggie and Laine eventually stopped at another random classroom. Catria felt like she'd been frantically chasing them for so long that somebody should have found them by now, though in reality it had probably only been a couple minutes.

"You guys are mean," Catria panted as she stumbled to a halt by her smirking siblings.

Any further grievances were forestalled as Laine kissed her. She melted her supple, naked body against him, allowing and encouraging his caresses.

Maggie had to shoo them inside the classroom where they had some actual shelter from unexpected prying eyes. Once Catria started getting kissed and touched in her aroused state, she never wanted it to stop, danger be damned.

While Maggie leaned casually by the door to keep watch, Laine lifted Catria onto the teacher's desk. He kissed her again, then knelt in front of her.

Catria giggled insanely and spread her legs wide at the edge of the desk. She was pretty sure she was dripping and making a mess, but she didn't care even a little. So what if one of her teachers might discover a pool of her pussy juices? She'd be gone, free from any repercussions.

Laine dove in to her wet little snatch with no dicking around at all. Catria arched her back and scooted forward even more, balancing precariously at the edge of her perch to give her brother the very best access she could.

Maggie was smiling crookedly from her lookout position. Her eyes met Catria's every now and then, in between hallway checks. Catria wanted so badly to kiss her, but was unwilling to do anything that might interrupt Laine.

Her dedicated big brother was licking her more intensely than he ever had before. There was very little technique being employed, and he mostly seemed to want to get her off as quickly as possible.

It totally worked.

Catria exploded in a surging, shivering orgasm. Laine's eager, puppy-like lapping combined exquisitely with her excitement and anxiousness to produce a beautiful climax. She actually squirted on his face, which she hadn't previously been aware she could do.

It turned out being semi-publicly eaten out by her brother kind of worked for her. Who knew.

Laine came up for a kiss, which Catria hungrily returned. Her scent and taste were all over his face, which in her state only aroused her more. She tried to lick him clean, but only got a few swipes of her tongue in before he laughed and stepped away.

Laine and Maggie, by unspoken agreement, swapped places. Laine took up lookout duty, while Maggie approached her slutty little sister with gleaming eyes.

Catria anticipated another pussy licking, and firmly approved of the idea. Maggie, however, had a slightly different plan. Catria was booted off her perch, only for her sister to take her place.

Maggie lifted her skirt and revealed a total lack of panties underneath. Turned out she was being kind of naughty too. Not 'naked in the middle of school' naughty, but still.

"What are you waiting for, an order?" Maggie asked.

Catria flushed, but it was Laine who answered. "Well it wouldn't hurt, Mags."

"Hush, Laine. No one asked you." Maggie looked firmly into Catria's eyes. "Lick me, little sister. You don't get your clothes until I cum."

A sharp thrill took Catria's breath for a moment, but she was already kneeling into position. She was pretty sure her siblings wouldn't actually leave her naked if danger of discovery arose, but the threat still did lovely things to her. It gave a sense of urgency that added to her insane desire to pleasure her sister.

Every moment they stayed increased their odds of being found out. Catria knew that. Laine and Maggie had to know that. Yet here they were, Catria's tongue working away at her sister's pussy, all willfully oblivious to their acute danger.

Maggie's fingers tangled in her hair. She heard the soft moans, and felt the subtle twitches that confirmed she was doing a good job. For a few brief moments, her whole world became her sister's pussy; its taste, its wetness, its connection to the pleasure centers inside Maggie.

Catria licked and licked with single-minded determination until Maggie came. She received a small gush of nectar for her efforts, and her head was momentarily clamped between soft, sisterly thighs.

Catria accepted some head petting and praise from Maggie. She was torn, because now that she'd earned her clothes back she knew she should put them on, but she didn't actually want to.

Her previous orgasm felt like forever ago. She was primed and ready for more after eating out her sister in an empty classroom.

"Ready to get dressed?" Maggie asked, still gently stroking her hair.

Catria looked up from her kneeling position. She hesitated, hoping that the choice would be yanked away, that she wasn't going to be allowed to put her clothes back on yet.

"Maybe not just yet," Laine said, coming to the rescue. He walked over, already in the process of undoing his pants.

Catria tried her best to repress a smile. Maggie just rolled her eyes.

"Seriously?" Maggie said. "Come on, Laine. You know we're pushing our time as it is."

Laine shrugged. "When am I ever gonna get another chance at school sex?"

"I don't mind," Catria said in a small, hopeful voice.

"No, of course you don't," Maggie said. She shook her head. "Whatever. Don't blame me if you two end up in jail over this."

Despite her words, Maggie took up sentry position again without any further argument.

Catria struggled to her feet on slightly wobbly legs. She lay her torso down across the desk and widened her stance a bit to try and get as stable and comfortable as possible without the use of her arms.

Her tummy landed in the warm puddle she and Maggie had made together on the edge of the desk. She wiggled a bit at first, unsure whether she liked the feeling, but decided the knowledge that she was getting all messy with pussy juices made it acceptable.

Laine rubbed his dick up and down her sopping cunt, then pushed it in with very little preamble. None was needed. Time was of the essence, and Catria could hardly have been any more ready for him.

Fast, hard thrusts left Catria temporarily short of breath until she adjusted. She arched her back and gave Laine a better angle, but mostly just let him fuck her.

There was no romance here, just quick and dirty sex. A girl getting pounded by her brother in school while their sister watched. It was so deliciously depraved.

Laine pulled his cock out, which confused Catria. She didn't think he was done yet, and indeed no hot spray of cum graced her backside. He did, however, rub his pussy-lubed shaft all over her butthole. He went back a couple times for more, and by the time he actually pressed against her ass for real, she was prepared.

"Yes yes yesss," Catria hissed, her eyes rolled almost fully back.

Her brother was a goddamn genius. Practically the only way to make the day better or more perverse was to stick it in her butt, and that was exactly what Laine was doing.

Catria didn't think she could have felt sluttier, short of a line forming in the hall to gang bang her. Her ass protested in sharp stabs of pain as Laine went a little too fast, but her pussy gushed like crazy and her whole body shivered in delight. She pushed back, forcing him all the way inside her tight butthole.

"Jeez, guys," Maggie muttered from the doorway. "You're going kinda crazy on me here."

Catria giggled maniacally and thrust her bum out for more. She adjusted to Laine's girth as he fucked her with increasingly smooth strokes, but there was still enough of a sensual ache to send little electric tendrils jolting around her body with every movement.

Her anally-induced orgasm was a whiteout of blinding pleasure. Her ass clenched accidentally, mixing a fresh batch of pain with her overwhelming delight. She must have started making too much noise without realizing it, because she was cut off by Laine's hand clapping firmly over her mouth.

Laine came in her butt shortly after, while she was still coming down. Jets of hot brother-cum splashed inside her, reigniting small flames of illogical passion with every burst.

"Fucking hell," Maggie said softly. She had her skirt pulled up enough to play with herself. Apparently watching her baby sister get royally and incestuously ass-fucked turned her on a bit.

"Ok," said Laine with a lazy and satisfied grin. "We can go now."

Catria struggled to stand upright. She was even more unsteady than before. She looked at Maggie, at Laine, then finally at Laine's cock. "Not yet."

Her siblings frowned as one. "The hell you say?" Laine said.

But Catria was already back on her knees, just below him, tongue stretched out for his penis.

She actually was crazy. She knew that. It was a perfectly acceptable time to call it and get out of there.

Except... except not quite.

Laine was softening. His cock was nowhere near fully hard anymore as she sucked it into her mouth. She bobbed her head anyway, hoping he'd be able to recover quickly. As hot as she knew herself and the situation to be, she wasn't certain it would be enough.

"Damn, Cat," Laine said, his hand hovering just to the side of her head, torn between pushing her away and letting her continue. "I just came."

"Nevermind that," Maggie said, eyes locked firmly on her sister. "That dick was just in your butt." Yet she didn't stop fingering herself.

Catria was well aware she was sucking something that had just come from her ass. There was a definite hint of the resultant unpleasant flavour. Fortunately, the tastes of her pussy and Laine's cum were strong enough to keep her from regretting her decision. She kept right on working her brother's shaft until it grew hard again in her slutty little mouth.

Catria maintained as much eye contact with her brother as she possibly could. She couldn't manage it constantly, partly because she had to keep flicking her gaze over to Maggie, and also because of her occasional losses of balance, but she did her best. Freed arms would have helped considerably, but their restraint and her dependence on solely using her mouth were a big part of the charm for her.

She loved the way her big brother and sister looked back at her. Their surprise and awe, and especially their lust fueled her sluttiness. She worked Laine's cock with everything she had, using her tongue and lips with all the skill she'd amassed from practicing on him. She needed him to cum again, just once more.

"We've created a monster," Maggie whispered just loud enough to be heard.

Laine only grunted.

Catria was rewarded with a smaller, but sufficient burst of cum. A few sticky ropes scarred her face as she pulled back just in time to catch them. She kind of wished she'd thought to take her brother's first load on her face, but she also was deliriously happy to have his cum snugly in her butt.

Laine tucked his cock away more swiftly this time, getting it protectively out of reach of more sex while it was extra sensitive. He then helped Catria stand, since she just didn't have it in her to get back up unaided.

"Ok," Catria said, grinning dopily. "We can go now."

"Let me guess," Maggie said. "You're not going to let us clean you up first."

"Only if you feel it necessary," Catria said lazily.

She was basically out of it. She was still quite horny and ready for more if pressed, but she was also pretty much ready to just nap for a bit.

Laine started to guide Catria toward the door.

"Hang on," Maggie said.

"No," said Laine. "We seriously need to go."

"I know that. I just need a second." Maggie pulled out her phone, aimed carefully, and snapped a couple pictures of her dazed, handcuffed, freshly fucked, cum-adorned little sister.

"That's a hell of a graduation photo," Laine said.

Catria thought that was hilarious and had to be shushed repeatedly as they tried to sneak back toward the front of the school.

Laine went on ahead to scout out their path while Maggie dragged Catria along as best she could. There'd been no real consideration for stopping to clothe their sister since she put up such a fuss when they suggested it.

"Ok, the ceremony's still going, but it looks like it's winding down," Laine said as Maggie and Catria caught up to him. "And there's no way we're getting to our car like this because a bunch of other sneaky buggers are already out there slipping away ahead of the crowd."

"Yeah, I didn't think we'd get away with that," Maggie said. "Would have been crazy. Cat parading naked through the parking lot...."

Catria smiled. "Nakey Cat parade," she agreed happily.

"No, Cat," Maggie said. "No nakey."

"No?"

"No."

"Oh."

In the interest of time and efficiency, Catria's robe was draped back over her and held in place as best as Maggie could manage without being too obvious about it. The siblings walked as slowly and casually as they could manage, doing their best to not get too close to anyone as they threaded through the cars in the parking lot.

They managed to pile into their car without anyone shouting in alarm, whereupon Laine gunned it out of there as fast as could safely be managed.

Maggie had taken the back seat with Catria, who refused to sit up and be buckled in.

"Cat, baby, sit up, please," Maggie said. "Don't be petulant."

"I'm not," Catria mumbled. She'd returned to sufficient coherency to sound just a bit shy. "I can't sit."

"You can't?"

"My butt hurts."

Maggie stared at her, totally incredulous for a moment, then laughed and dropped the subject. "Oh my poor, slutty sister." She stroked Catria's hair. "You're going to have to learn your limits."

"What fun would that be?"

Catria stretched out across the seat, as much as she could, and settled her head in Maggie's lap for more scratchies

"Yes," Maggie said softly. "What fun indeed."

****

It was late in the morning before Catria woke up the next day. She was kind of disappointed to find no siblings in bed with her, nor even her hands cuffed the way they usually were.

Honestly though, she'd been so exhausted by bedtime the night before that she didn't mind a little lonely lazing time for herself first thing. She wasn't ready for any sexy adventures right out of the gate. Plus her ass still ached.

Catria grinned as she remembered the previous day. Despite residual pains and sleepiness, it had all been totally, unequivocally worth it.

After getting home, she'd played pet for most of the rest of the day. She'd snuggled and cuddled and accepted head scratchies whenever they were offered. Maggie and Laine had fucked around with her some more too, at least until she was worn out to the point she couldn't muster proper enthusiasm.

And now she was free. No more school. Just her and her brother and sister. Except when they had things to do, of course. She probably couldn't demand that they both quit their jobs to stay home and play every day.

Catria finally dragged herself out of bed when her bladder became too insistent to ignore. A shower helped wake her up and get her in the mood for the day. It also gave her a chance to cleanse and prod some of her sensitive areas to gauge how much she'd recovered.

She didn't bother getting dressed before venturing off in search of siblings. She padded softly down the hall, all fresh, pink, and scrubbed.

There was a present sitting in the middle of the kitchen table. Catria sneaked close and bounced excitedly on her toes. It was a fancy glittery bag stuffed with tissue paper, and no amount of peeking and peering gave away what was inside. She wanted to tear into it like a child on Christmas morning, but wasn't quite sure if she should.

Maggie and Laine were playing video games in the living room. Or, rather, Maggie was playing and Laine was doing his best to instruct her. Catria guessed by the small, knowing smirk on her sister's face that she was playing deliberately poorly in order to annoy him.

Catria got appreciative glances from both her siblings as she walked in, but they carried on their silly game anyway. She didn't like that she could walk in naked and not get a reaction, but the feeling was also just demeaning enough to kind of work for her. She stood still and ignored for as long as she could, which wasn't long at all, and nurtured that interesting little seed of light humiliation.

"Morning," she said shyly once she could stand it no longer.

"Hey, Cat," Maggie said. "I'll just be a second. I'm kicking this guy's ass."

"You're barely winning and it's your third try," Laine said tiredly.

Maggie winked at Catria with the eye Laine couldn't see. "He's just jealous of how good I am."

Catria smiled, but she still wasn't being lavished with attention and lust, which just wasn't right. She clasped her hands behind her back and shifted her weight uncertainly. "There's a present on the table."

"So there is," Maggie agreed.

"Is it for me?"

"That depends," said Laine. "Did you graduate yesterday? And are you the sexiest baby sister living here?"

Catria brightened up. "Yes," she said firmly.

"Then that'd be your present, alright."

She dashed back to the kitchen, grabbed the bag, and practically skipped upon returning.

Maggie was already putting the game away, belying her and Laine's previous fascination with it over their slutty sister who should rightfully be getting all the attention. She made room for Catria in the middle of the couch.

Catria happily popped down in the vacated space, snuggling in between her brother and sister. She dug eagerly into the bag. She had no idea what to expect, aside from assuming it was a sex toy of some kind.

She was very confused for an instant upon pulling out what seemed like a very small belt. That didn't make sense to her at all. She quickly realized what she was actually holding, and her jaw dropped. Her head whipped back and forth between her siblings.

"For me?" she squeaked.

"Of course for you, silly," Maggie said, kissing her cheek.

"It seemed like the right thing to get you," Laine added while casually sneaking in a feel of her tits.

Catria felt actual tears brimming. "You guys are the best." She gave them each a big, naked hug. "I love you."

She pulled her hair out of the way and held statue-still while Maggie took the collar from her hands and snugged it into place around her neck.

"We love you too, little one," Maggie assured her. "Always."

Catria traced the line of the collar around her neck. It felt a bit odd to her, purely because she wasn't used to wearing anything there, but she absolutely adored it. She was their pet now. It was practically official. Their little sister-pet. The collar even had a medallion hanging off it that simply read 'Cat'.

"Did you get a funny look for getting a dog collar with 'cat' written on it?" Catria asked, her voice slightly distant along with her mind.

"It's actually specifically a people collar," Laine said. "But yeah, we kinda did. I think the guy wanted to make sure we weren't getting it for an actual cat, but he didn't ever dare ask."

"And we didn't volunteer," Maggie added. "None of anyone's damn business, really."

Catria giggled as she got double kisses on her neck and shoulders from both sides. Every movement drew her attention to her new adornment. She savoured the moment, because she knew it would fade with time, the same as her handcuffs were no longer the novelty they'd once been.

"You hungry?" Maggie asked.

Catria nodded. "Starving, actually."

"I'll see what I can do. Laine, you mind finding her cuffs?"

"Sure thing," Laine said.

It felt even better being securely handcuffed while still riding the thrill of her brand new collar. Catria snuggled wantonly with her brother while she waited for food.

Laine fondled her as his whims took him. He mostly played with her tits, though occasionally slipped his hand between her legs and fingered her.

Catria encouraged every little feel. She rubbed herself on him, closer and closer, until she was practically in his lap. She couldn't actually get his cock out by herself, but rubbing all up on him convinced him to do it for her.

After having his cock teased a bit, Laine grabbed her by the waist and dragged her on top of him. She giggled in delight, then sighed happily as he sank into her pussy.

Maggie rolled her eyes when she returned with Catria's breakfast, only to find her sister grinding on Laine's lap. She said nothing, however, and knelt down next to them.

She offered small pieces of food to Catria, who took them carefully with her teeth, then ate while still wiggling around on her brother's cock.

"I took the day off," Maggie said. "And Laine wasn't working today anyway. Is there anything you want to do?"

Catria chewed her bite thoughtfully. "Maybe just hang out," she said. "I'm not really feeling all that energetic right now." She bit her lip. "Do you think I'd be able to get away with wearing my collar outside? Like, just down the street or something?"

Maggie hesitated. "Is that something you actually want? Or something you're just wondering about?"

"I dunno. I guess just wondering right now." Catria shrugged. "I kinda want people to see it, but also don't want them to."

"It's not technically all that bad, really," Laine said. "It's not like it's necessarily sexual."

"No," said Maggie. "Not necessarily. But it is in this case. If you really wanted to show off, it'd probably be better to go somewhere people are less likely to know us."

Catria nodded. "That makes sense. I don't think I'm brave enough for that right now anyway. Just something I was thinking about."

She finished her breakfast, gently riding Laine all the while. By that point she was horny enough that she had to fuck him harder and get herself off. She had a nice little cum while Maggie was sitting right beside her, trying to pick out something to watch.

Maggie's outward indifference was, in fact, too much to resist. Catria went for her next, getting all nuzzly and kissy at first, then trying to get at her pussy. The latter turned out to be nearly impossible. She basically could not get into her sister's pants with only her teeth.

Maggie struggled to hold a straight face at Catria's hopeless, sexy antics. She finally relented and took her bottoms off, then sat back spread-legged and let Catria get at her vagina.

Laine took over the selection of a show both he and Maggie could agree on. The two of them debated vigourously, despite Catria's best efforts to distract her sister to the point of incoherency.

The occasional stroke of her hair was about all the recognition Catria was given. She looked up at Maggie from time to time, but was studiously ignored. Maggie was getting seriously good at pushing her buttons.

Catria got more and more desperately horny as she tried to lick her sister's pussy skillfully enough to get some acknowledgement. The occasional soft whimper or clenching of thigh muscles around her head were worth more than all the lavishing of praise she could have expected from normal sex. Maggie was trying not to give her anything, which made the slip ups all the more genuine.

Only after Maggie came did her act break down entirely. She pulled Catria to her lap and kissed her deeply while also grabbing her butt.

Catria submitted happily to kisses and fondling. She felt sexually victorious after having defeated her sister's feigned nonchalance with nothing but her tongue and an excess of determination. The downside was that she was left even hornier than before, and her attempts at grinding on Maggie's lap didn't really work out.

Catria was so into her wiggly snuggling that she didn't notice Laine taking off his pants until he grabbed her and dragged her off of Maggie. She squealed indignantly for form's sake, while actually enjoying the hell out of it.

She was bent unceremoniously over the arm of the couch, facing her still bottomless sister. Maggie wasn't even looking, seemingly unaware or uninterested. It was no less an act than before, but it was convincing enough.

Catria tried to emulate Maggie. She stayed still and pretended to watch tv while Laine rubbed his cock over her slit. She couldn't totally hold back her reactions, but she did pretty well. Even when Laine penetrated her, she managed to only bite her lip and hold back her instinctive moan.

It was a fun little game playing a living fuck doll. She enjoyed the physical aspects of sex with her brother just as much as she ever did, and the mental thrill of acting like he could do whatever he wanted with her whenever he wanted to was absolutely amazing. Wearing both collar and cuffs, the better to help her feeling of submission, was a nice bonus.

Laine eventually came all over Catria's butt. Her composure totally broke down at that point, and she hissed and wiggled in deviant pleasure as hot streaks of cum lanced across her ass. She loved the feeling on every conceivable level.

Catria stayed right where she was, acting overly obedient and submissive, as Laine retook his seat. He glanced at her with a raised eyebrow, and she pretended not to notice. She remained bent over, pussy nicely presented, like it was her job.

Laine rolled his eyes and took hold of the small ring on the front of Catria's collar. He dragged her back around onto the couch like he was maneuvering a puppy who'd escaped its leash somehow.

It took some work finding a comfortable position. Catria couldn't sit down without making a cummy mess, so she ended up lying more or less on her side, legs curled up a bit, hands still firmly behind her back. Her butt was in Laine's lap, and her head in Maggie's.

Laine's finger traced small, lazy spirals across her ass. The patterns got slippery every time he intersected a line of cum. Occasionally he'd scoop some up and probe at her butthole, though not hard enough to actually penetrate yet.

"We should make a doctor's appointment," Maggie said.

"We should?" Catria asked, unsure where the apparent non-sequitur had come from.

"You really should be on birth control," Maggie said. "If we're going to keep doing things like this. And I don't doubt that we are." She slid a delicate fingernail up Catria's side, making her giggle and flinch away. "I, for one, don't want to end up raising an accidental incest baby."

"Good call," Laine said. "No point risking it."

Catria went a different direction in her head. She knew Maggie had a good point, but she couldn't help twisting it into her sister helping her out a different way; which was to say, making it acceptable for Laine to cum in her pussy.

It had never really been part of her fantasies before, since sperm anywhere near her uterus was just something ingrained in her as being bad. She supposed she'd been a little slow in realizing that since there were various options for birth control out there, not just condoms, she probably could have been looking into it on her own.Now that the subject had been broached, Catria was already planning out scenarios where she could get her brother to cum in her pussy and ass, and then once more in her mouth. Her mouth would have to be last for sure, since she couldn't hold cum in there nearly as long.

Great. Now she was horny again.

Laine was helping a little. His finger had gone partway up her butt, which was at least an interesting feeling, even if it wasn't really sating her desires.

Catria knew she wouldn't be able to hold out forever without some more physical play time than that, but she was too comfy and settled to want to move just yet.

****

Laine was having a pretty good day. Cat's new look with the addition of her collar really was the culmination of her recent sexual journey. He absolutely loved seeing her wear it.

It wasn't just that the collar looked pretty hot on her, in a fetish-y kind of way, but also the way she clearly enjoyed wearing it. He caught her in the bathroom at one point just admiring herself. She blushed shyly at being noticed, but didn't stop posing for herself.

Cat didn't know it yet, but there was a leash that went with the collar too. He could only imagine how excited she'd get over that. Hell, he was excited, and he wasn't nearly so into the whole bondage thing as she was.

Otherwise, the morning was basically spent doing nothing of any real consequence, other than toying with Cat. Laine and Maggie took turns with her, or sometimes shared her as events warranted.

Laine saw a lot of Maggie, and vice versa, since neither of them much bothered trying to preserve modesty. It would have been a fool's errand. He wasn't quite sure how to feel about it, though it generally just didn't bother him as long as Cat was present to act as a buffer.

He appreciated Maggie's body, but she was still purely his sister in his mind, rather than the sister and sex partner combo Cat had become. The caveat being when Maggie and Cat were doing stuff together. He thoroughly enjoyed watching them, with none of the conflict that Maggie alone made him feel.

Possibly Laine's favourite part of the morning came when Cat was eating out Maggie, and he started fucking her from behind. It had been a moment where he wasn't even thinking about how weird it might be to technically engage in a threeway with both his sisters. He'd just been aroused from watching their antics, and had been caught up in the game of 'treat Cat like a sex toy' they were all playing.

Maggie had seemed amused when they'd made eye contact while each using one end of their sister. Laine had shrugged and tried to focus on Cat's butt rather than Maggie's face. The actual end result had been a compromise wherein he spent a lot of time staring at where Cat was licking Maggie's pussy.

There had been a break afterward where Cat was temporarily uncuffed and sent to clean herself up. Laine and Maggie sat on the couch, only barely clothed at all, and studiously not looking at one another.

"Do you think we're taking this too far?" Laine asked.

"No," said Maggie. "Cat's loving it. She's--"

"No, no. Not Cat. I meant just, like, us."

Maggie was quiet a moment. "You mean like how we're sitting here half-naked together?"

"Yeah. That kind of thing." Laine risked a hesitant glance. "I mean, we've seen each other plenty at this point, but I'm not sure if that's a good thing or not."

Maggie shrugged. "Me either." She met Laine's gaze. "You don't want to do stuff with me, do you?"

"I... don't think so?"

"Good. Let's try and keep it that way."

"The classic 'look but don't touch'?"

Maggie gave a half-smile. "Something like that." Her eyes flicked down to Laine's mostly soft cock. "I mean, you're alright to look at and all, but you're still my brother, you know?"

Laine nodded gratefully. That was more or less the position he'd arrived at too. "I get ya. Cat's our sister, but she's... like...."

"She's Cat," Maggie finished for him. "She's unique. She's an outlier, and not to be taken as an example for how to behave with family."

"Yeah. That."

****

Laine had to run out and do an errand after lunch, which left Maggie in charge of Cat.

Lunch itself had involved Maggie getting her strapon out and making Cat ride her while being fed by Laine. That had been kind of fun.

Once Laine took off, Maggie had something else she wanted to try. Something, admittedly, not quite so directly sexual, but that would hopefully push Cat's buttons the right way.

"You know what you're going to do now?" Maggie asked Cat as she unlocked her handcuffs.

"No," Cat said, breathing noticeably shallow in anticipation.

"Well, the dishes have been piling up a bit."

Cat frowned, confused. "So?"

"So you're going to clean up the kitchen."

Cat's frown didn't go anywhere. "I am?"

"You are."

"But... but...."

"And I'm going to watch you," Maggie said with what she hoped was the correct inflection to achieve the desired effect.

It seemed to work. Cat bit her lip and considered, then eventually nodded.

"Ok," Cat said.

Maggie had never tried using her sister's proclivities to get housework done before. Or for any kind of constructive purpose, really. But it made sense, in its own way. It was slightly demeaning, and at least a little bit sensual since Cat would still be naked and collared.

Maggie did just what she'd said and sat down at the kitchen table while Cat got to work. Bizarrely, helping out would probably have had a lower success rate. By just watching and acting bored, she could feed into Cat's fantasies and make chores interesting for her.

That was the hope, anyway.

There would have to be experimentation done, to determine how to get the best results. In this case, Cat kept peeking over her shoulder to see if Maggie was paying attention. She seemed to quite like when Maggie was staring at her butt, but she wiggled for attention if she wasn't getting it, which hurt productivity. If Maggie met her gaze, she'd whip her head back around, sometimes with an embarrassed squeak.

Overall, the process took longer than if Maggie had just washed the dishes herself, so that needed to be worked on. Ideally she'd be able to get Cat working independently, perhaps simply with the occasional walk by or the promise of a reward at the end. It wouldn't matter so much if a task took twice as long as it should, so long as Cat could be persuaded to work away without constant supervision.

Cat let the water out of the sink while Maggie was still daydreaming. She padded closer, then stood with her wrists held behind her back for recuffing.

"So was this a game?" Cat asked. "Or did you just not want to do dishes?"

"Why can't it be both?" Maggie wrapped her arms around Cat and kissed her neck. "I hope you realize I expect more chores out of you than what you've been getting away with."

"Like... a lot more?"

"Yeah. A lot more. Even when I'm not around to stare at your butt while you do them."

Cat shrugged awkwardly. "I'll try."

Maggie's hand slipped down to Cat's pussy. She idly fingered her sister's wet little slit. "Don't worry, I intend to make it fun. It's a work in progress, is all."

Cat melted back into Maggie as she was caressed and teased. "I kinda liked it when you were watching," she admitted softly.

"Yes, I know. But I can't watch all the time." Maggie drew a small circle around Cat's nipple, carelessly smearing some of her own pussy juices across her breast. "So we'll have to be more creative than that."

"Ooh."

Maggie toyed with her a bit more, then stepped away. Cat almost fell down, but only stumbled a bit. The way she pouted at the sudden betrayal and cessation of sexy time was too adorable for words.

"Perhaps," Maggie suggested thoughtfully, "if you fetched your butt plug...."

Cat's eyes lit up, her pout fading away like a summer breeze. "Really? But you never--" She stopped and shook her head slightly, as though realizing she might be arguing herself out of something fun. "Ok," she said instead.

Cat scampered off eagerly and returned moments later. She cradled the plug Laine had got for her in her hands. She bit her lip and held it out for Maggie.

"Uh uh," Maggie said. "I don't want it." She pulled out a chair. "Set it here."

Cat tilted her head uncertainly, but did as she was told. She set her butt plug on its base, facing up.

"Perfect," Maggie said. "Now, then. You're going to sweep the floor."

Again, Cat's face registered confusion, and perhaps a little disappointment. "I am?"

"You are. And once you're done, you're going to get one chance to insert your plug." Maggie waited until Cat had processed and was about to speak. "Without using your hands."

That preemptively shut Cat up. A small, shy smile spread across her lips as she figured out at least some parts of what her sister was asking of her.

"Do I get a try first?" Cat asked.

"Nope. One room swept, one try. You know where the broom is." Then Maggie leaned back and let the fun happen.

Maggie was quite certain Cat had never, ever swept the floor with such enthusiasm. She didn't even keep checking in to make sure she was under constant observation. The promise of something interesting afterward seemed to have helped significantly. It still wasn't a fast process, exactly, but some more experience would help that.

"So... no hands?" Cat asked upon completion. "Are you sure you don't--"

"I can't cuff you, little one. Because I'd just have to uncuff you again to do the next room."

"And what if I do it first try?"

"Then I guess you'll have outsmarted me."

Maggie wasn't particularly worried about the possibility, though admittedly it would monkey with her plans a bit. Cat's plug was a decent size, as far as she understood these things, and she was confident it would take some work.

Cat tried her best. She knelt down and just stared at the plug for a moment, no doubt mentally strategizing. She then carefully licked and sucked on it, drooling all over it just as much as could.

Maggie wouldn't have wanted to let something that had been up her butt anywhere near her mouth, but it turned out Cat had no such qualms.

After slobbering copiously over her toy, Cat straddled the chair on which it sat. She braced her hands on the back of the chair and began to lower herself.

"No hands!" Maggie said sharply.

"But...." Cat blushed. "Sorry."

She took her hands off the chair and tucked them behind her back as though they were cuffed together. She tried lowering herself again, but only succeeded knocking her butt plug over. The dismay that washed over her face was almost enough to make Maggie burst out laughing.

"Better grab the broom," Maggie said lightly.

Cat pouted and cast a wistful on her plug, but she got to work and did the next room. She made even better time, relative to the size of the rooms, than she had with the kitchen, and was soon back for another try after Maggie reset her toy for her.

Again Cat sucked and slobbered, but this time she was more careful with her anal approach. She managed to land on her butt plug without knocking it over, but she hadn't lined it up well enough. Her attempt at lowering herself further pushed the plug away from her asshole instead of into it.

"I know, I know." Cat sighed. "Next room."

Maggie nodded, and was unable to hide the small smile that crept over her.

And so Cat progressed through the house. She got better at hands-free butt plug insertions, but quickly ran up against the limitations of spit as a lubricant, and her butthole's need to be gradually stretched out to accommodate her plug.

Cat almost got her it in after the last room, but couldn't quite make it past the widest bit without hurting herself. She pouted with pleading, frustrated eyes.

"I almost got it," she whined.

"Yes, you did," said Maggie. "Almost. I guess you're gonna need another try."

Cat reluctantly nodded. "But I'm all out of floors to sweep."

"So you are."

"So then... what do I do?"

"You tell me."

Cat thought about it while standing up and letting her butt plug pop back out. "I could... make my bed?"

"Uh uh. A real chore. Don't give me nonsense like that unless you want me to decide for you."

Cat shrank back. "Um... what about...."

"Quickly, quickly, little sister."

"I can make cookies," she said with a hint of panic. "I could... if...."

Maggie held in her agonizing suspense for a moment, then nodded. "That sounds fine. But you'll clean up after yourself afterward. That will give you two tries, if you need them."

"Ok. I mean, I haven't really made them from scratch before. Not by myself. I might need some help."

"You'll do fine," Maggie said firmly, forestalling any further attempts at dragging her into assisting. That wasn't the point of the exercise, after all. "Remember, your plug is waiting."

Cat nodded and bounced away with fresh energy and determination. She had a recipe book out and the oven preheating before Maggie could even sit down.

It was really working out now. Cat had gotten into the game more than Maggie had hoped. The challenge of plugging herself was more of an impetus than expected, as Cat seemed to view each failure as a petty annoyance that needed rectified, so to speak.

Maggie had honestly only expected Cat to enjoy the pleasure and humiliation of trying unsuccessfully to stick something up her butt while being watched. It was very interesting to note other motivators, and she fully planned to make use of similar challenges in the future.

Despite her own goal of getting Cat to work by herself, Maggie found herself hypnotized by her naked, collared sister as she padded back and forth around the kitchen. Part of it was that she was daydreaming and scheming, and Cat was merely a convenient eye-catcher. Another part, though, was the way Cat moved when she focused on something other than sex.

Maggie really hadn't spent much time with Cat while she was both naked and not looking for attention of some kind. It was a beautiful and more natural look for her, and made Maggie feel some odd but very pleasant things.

Once Cat had the cookies in the oven, she immediately set to work on the dishes and tidying up without being told. Maggie couldn't help herself at that point. After disappearing briefly, she returned with a bottle of lube and snuck up behind Cat.

Cat giggled as Maggie fondled and nuzzled her from behind. She kept washing up, but her progress slowed dramatically.

Maggie nibbled and teased a little more, then opened up the lube. She normally didn't have all that much interest in participating in anal play, but Cat had earned some help.

She easily inserted a slippery finger into Cat's warmed up butthole and thrust it gently. Cat stuck her bum out, eagerly accepting some sisterly ass-fingering.

Maggie didn't go so far as to lube up the butt plug as well. That was still Cat's responsibility.

It was enough, though. After slobbering all over her plug yet again, Cat finally managed to insert it, by herself, no hands.

Cat's eyelids fluttered and her mouth opened small and round as she sank the last little bit into the chair, then she was all smiles.

"I did it," she proclaimed as though Maggie hadn't been watching the whole thing.

"So you did," Maggie concurred.

Cat wiggled around a bit, then stood up. "I'll be able to do it better next time. I kinda got the hang of it now, I think."

"I'm sure you do. But if you get too good, we'll just have to find new challenges."

Cat's grin only widened. Apparently she didn't mind that idea one bit.

****

Laine arrived home to fresh-baked cookies, which was always nice. Even better when there was a little sister-slut around somewhere waiting to be played with some more.

He was getting as bad as Cat. He needed to watch himself. Or actually, he probably didn't. The pervier he thought, the happier she'd likely be.

Case in point, Maggie and Cat were right back in front of the tv. Cat was snuggled up in her sister's lap, looking for all the world like an actual kitty who'd found itself suddenly human and didn't know what to do except revert to old habits.

"Someone's been having a good time," Laine said. He munched on his second cookie as he sat down next to the girls.

"We've been playing a fun game," Maggie confirmed. "Haven't we?"

"Mmhm," Cat said.

"Motivating the little one to do some chores," Maggie added. She grabbed Cat's ass cheek and pulled it to expose the base of the butt plug hidden up her ass.

"My my," Laine said, arching an eyebrow in genuine surprise. "It really was a fun game."

Cat giggled and snuggled more securely into Maggie's lap.

Laine decided they were probably having a moment of sorts, and that it was best not to interrupt just yet. There was no rush. Cat wasn't going anywhere.

Indeed, there was quite a lull in activity for the next little while. Cat was, as always, totally happy to be touched or played with, but didn't quite seem to have the energy to play back. Laine mostly let her rest, though he did occasionally feel her up a bit just for fun.

It was well into the evening by the time Cat was back to her unmanageably horny self. She lured Laine to her room, which didn't really take much persuasion, and they were soon fucking around like she hadn't had any sex all day.

Cat still wore her collar, as Laine had expected. He was glad to see that he and Maggie had done well and hadn't accidentally bought one that dug in or chafed too bad.

Laine experimented with controlling Cat via her collar. The results were actually scarily good. With his finger stuck through the collar's ring, he could basically move her head around as he liked. Cat could be sucking him off, and if he gently eased her away, she'd be good and not even fight him, though she would adopt an annoyed, pleading look with her mouth held enticingly open.

He could only tease and play so long before he had to actually fuck her. Cat purred happily as she was positioned on her bed with her ass up in the air, then pounded from behind by her beloved big brother.

Laine had no idea how long Maggie was watching for. All he knew was at one point he happened to glance at the doorway, and there she was; watching, smiling, bottomless, strapon dangling casually from one hand. They stared at each other a moment, then Laine nodded his head toward Cat in invitation.

Maggie glided over and sat down in front of Cat. She scooted closer until her pussy was positioned for licking.

It was insanely casual, really. All three siblings just kind of falling into bed together, like it was a normal thing to do. Nothing about it was normal. And yet, it was comfortable. Nice. And crazy hot.

Every time he saw it, Laine became further convinced that he loved watching Cat lick Maggie's pussy. He couldn't help it. He just did. Maybe it was the expression of love and lust that he could never see from the outside between he and Cat, or maybe it was just the basic girl on girl action that worked for him. He didn't really know one way or the other.

Laine came all over Cat's ass and lower back. She hissed and arched her back, then wiggled her butt in case she could coax any little bit more out. Maggie wouldn't let her stop licking long enough to do any more than that.

Laine switched places with Maggie after that. Maggie attached her strapon, then took over dominating their sister's vagina. It was pretty hot, but Laine still preferred watching her and Cat's oral action.

His cock had gone too soft and sensitive to simply shove down Cat's throat the way she almost seemed to expect. She made do with small, adorable, teasing licks. She slowly cleaned Laine's shaft up while he, in turn, slowly hardened back up.

Cat got well fucked from both ends for a while. Laine lost track of the total number of times she came, but she had basically been in a state of near-permanent ecstasy ever since she'd started getting double teamed by her sibbos.

All three of them were wearing down by the time Laine came again. He shot his load into Cat's mouth, then sagged back, pleasantly tired and spent.

Cat tilted her head up and opened her mouth to display her now-gooey mouth. Laine chuckled and patted her head.

"Swallow," he said.

Cat closed her mouth, then opened it again. It was empty.

"Good girl," Laine said with another loving pat.

Maggie had been down to a slow, gentle rhythm by then, and she took Laine's finishing as a convenient stopping point. She pulled out and sat back, then traced her fingers along Cat's damp thigh, admiring her work.

With no siblings left inside her, Cat curled up between Laine and Maggie. "Is it bedtime?" she asked, just before trying to stifle a yawn.

"Very nearly, I think," Maggie said. "I know I won't be up very late tonight."

Cat nodded with half-lidded eyes. Then, abruptly she bit her lip and opened her eyes wide and disarming. Her gaze flicked back and forth between her siblings. "Would you both stay here? Like, for the night?"

Laine and Maggie exchanged a glance.

"You want us both to sleep with you?" Laine asked.

"Yeah. Just tonight. I know it's weird for you guys." Cat contrived to look even more pleading and adorable. "I think it'd be nice."

"Your bed's not really that big," Maggie said.

"It's big enough," Cat protested. "I won't take up much room. I'm only little."

Laine eyed Maggie, sizing up her mood and how real her protest was. "We can use my bed. It's bigger."

Cat smiled cautiously.

"Really, Laine?" Maggie said. "That might be even worse. It'll be weird. Cat's bed's one thing, but yours?"

"It won't be weird," Cat insisted before Laine could say anything. "I'll stay in the middle."

"Damn straight you will." Maggie hopped off the bed. "Well, if we're doing this, I'm not going to bed with my snatch hanging out."

"I won't look," Laine said.

"Yeah, I'm sure you won't," Maggie said, flipping him off over her shoulder as she left the room.

"Thanks, Mags," Cat called after her.

"Both of us, huh?" Laine said.

Cat squirmed. "Well... yeah. It just feels like it would be nice, you know? It was such a good day and all...."

"I kinda get that."

"You do?"

Laine nodded. "I think so. Like how cuddling after sex is nice, and you've been doing sexy stuff with me and Mags basically all day, so... yeah."

Cat grinned sheepishly. "Something like that. You're ok with it, right? 'Cause you don't have to if you don't want to."

"Trust me, I know that." Laine leaned down and kissed her forehead. "Just don't expect this to happen again, is all."

"No, I know." Cat lay her head on Laine's thigh. "This whole day, and yesterday, they've been wonderful. And I know it's not gonna last. I know you and Mags have been treating me special. It's been wonderful." Cat looked up with heart-melting eyes. "I just want one night with both of you. That's all."

"Goddamn, Cat," Laine whispered. "It's not fair being that cute."

"Sorry."

"Yeah right." Laine sighed as he scooted off the bed. He really didn't want to move. "Come on, we better get you cleaned up."

"Do we have to?"

"Yes. You still have cum on your butt, and I don't want that all over my sheets."

"Fiiine."

Cat acted reluctant, but Laine was pretty sure she enjoyed having him clean her up. She held still in the shower like she'd never washed herself before, and somehow Laine found himself easily slipping into some kind of caretaker role. Even after he realized what was happening, it didn't bother him enough to stop. Plus, it wasn't like he minded running his hands all over his sister's tight, wet body.

Once Cat was basically rinsed off, Laine took some time to examine her neck and wrists, the areas her bondage equipment had been occupying off and on all day. Her wrists were basically normal, as they were used to it, albeit perhaps a little paler than the surrounding skin. Her neck seemed a bit red, with some faintly indented marks that he could only detect with his fingertips.

"How's the collar fitting?" Laine asked.

Cat reddened slightly, but she also smiled wide. "I love it!"

"I know that. But is it, like, uncomfortable? Digging in maybe?"

"Only a little sometimes. But I kinda like that it reminds me it's there."

"Of course you do." Laine gave another cursory finger inspection of Cat's neck. "We can get you another one sometime if you want. One that we try out before we buy."

But Cat shook her head firmly. "I like the one you got me. It's mine."

"Yes. I thought you might think that way."

Laine patted them both down with towels, then escorted Cat to his room. He cuffed her, but left her otherwise naked for the night. She didn't argue about wearing her collar, which was good, because he had no intention of leaving it on her overnight until she was more used to it.

Cat was clearly fading fast. She rolled haphazardly into the middle of Laine's bed, and there she stopped. Laine smiled and lay down beside her. He didn't bother with the covers just yet since they were expecting Maggie still.

In the meantime, Laine lay quiet and still too, just watching Cat. She was so beautiful, and she did things to him that no one else had ever made him feel. Not even sexual things, necessarily. Although, really, they were mostly sexual to some degree.
