#18 of I Love You Twice

After a long week in classes, Dave Parrish thinks he has an idea for an after-school activity that will help him and his beloved sister Kelly wash away their stress and begin to enjoy the weekend.

The nice thing about timing my last story for getting posted on April Fool's Day is that I get the rest of the month to work on stuff. So here we are again, early in May, joining our favourite pair of kitties in a rather more explicit story than last time. I kept hinting at shower stories in the ends of previous chapters anyway, so I figured I owed you guys. ;-)

Special thanks to RoninDrake for helping smooth out the flaws with the story. n_n


I Love You Twice: Coming Clean By Green

As ever, there were audible sighs of relief when the final bell of the day rang. David Parrish, a tall, handsome black cat, gathered his books and stood up as the teacher told them which chapters to read over the weekend. English wasn't Dave's favourite subject, but at least he was good at it; he tried to push the chemistry test next week as far out of his mind as he could. It was Friday, so he had a whole week before he had to deal with those horrible arcane symbols and gibberish formulas. Handily for him, his locker was right outside his English class, and as he emerged into the hallway of Andrew Stanton Secondary School, he saw his best friend, a lop-earred rabbit named Danny McDuff, come out of his own last session of the day, a geography class. Danny came over and leaned against the wall next to Dave, tilting his head back and closing his eyes. "Man," he said, "they should make the dude who invented weekends a saint. Feels like a miracle to me, anyway." Dave gave his friend a sideways glance as he put his textbooks in his backpack. "You been planning that one for a while?" he asked, good-humouredly. Danny laughed to himself and shrugged. "Well, you need something to keep your mind occupied during Mr. Castner's lectures," the rabbit said, "Man! The first day in his class, I thought he was kidding, doing an impression of Ben Stein from Ferris Bueller or something!" Dave gave him a grin as he stood up, glancing through his locker to make sure he hadn't missed anything. His eyes lingered on the blank inside of the door; he'd considered putting a photograph there, maybe a group shot to avoid looking odd, but in the long run he couldn't risk it. Trying to put his frustration out of his mind, he hefted his bag onto his shoulder and secured the lock, swallowing a sigh of frustration. It was just another thing he'd come to accept with his unique lifestyle. Together, the friends made their way down the hallway, through the noisy, milling crowd, heading around the corner to the main stairwell, coming to a nice view of the main atrium, a large, open area where all the looping halls in the school met; Danny's locker was in the identical hallway directly underneath the one Dave's was in.

As they descended, trying not to be jostled by the sudden flow of students going up and down the stairs, Dan turned to his friend, regarding him faux-suspiciously. "You still coming over tomorrow?" he asked, "Or is something else going to suddenly come up?" Dave made a dismissive noise and shook his head. "Come on man, don't be like that," said the cat, now feeling genuinely apologetic, "You know I'd rather be hanging out with you than helping my old man clean out the garage or driving Kelly to some stupid party." Tuesday night, Dave had in fact been distracted by his younger sister, but it had not been to act as her chauffeur. "I know, I know," acknowledged Danny, "It's just... three times now, man! You were supposed to come over for co-op last Saturday, and it keeps getting pushed back, I feel like I never get to see you anymore. Now I know you haven't suddenly lost your love of shooting aliens in the face, so I was just worried that, I don't know, that I'd done something to piss you off, or Clover had said something to you..." he trailed off, looking away. Lop-ears didn't really change much for body language, but Dave couldn't help but think that the low-hanging appendages really emphasized the rabbit's awkward embarrassment. "No, it's fine, dude, we're cool. Haven't seen your sister since Valentine's Day anyway," he said, trying to sound encouraging. It was a simple fact that Dave was no fan of Danny's college-aged sister, and that the feeling was mutual. While living on-campus, she'd joined a 'Traditionalist' lifestyle that believed Morphics should be more in touch with the ways of their feral ancestors - though not to the extent of the 'wildkin', who tended to live naked in the wilderness - and in doing so, had gone from calling herself 'Veronica McDuff' to 'Cloverleaf', which was apparently a traditional rabbit name, and adopted a vegetarian diet. It also meant that she firmly believed that prey species like rabbits should not mingle with predator species like cats, and openly frowned upon her brother's friendship with Dave. "Trust me, Danny," Dave continued, "Even if Veronica had said something to me, I'd just try to get tighter with you just to piss her off." He sighed, shaking his head. "I hope your Dad's right about this being a phase, she was fine before she turned into a hippie," he muttered, then turned to his friend as they headed down Danny's corridor. "Anyway, yeah, I swear, even if the girl of my dreams tries to get into my pants tomorrow, I will be coming over to your place. No more excuses!" Daniel smiled at that. "Well hell, Dave," he said, smirking, seeming more himself, "if the girl of your dreams tries to get into your pants, bring her over! Maybe if you're good I'll let you use the guest bedroom..." The two friends laughed at that, and bumped fists together. Dave meant that, too, even though Danny had no idea that Dave had already found his soulmate, and it was entirely possible that she really would try and get into his pants on Saturday. 'The sacrifices you make for friendship...' he thought. As they arrived at Danny's locker and the rabbit knelt down to put down his books and attend to his lock, nose twitching with his concentration, Dave looked down the hallway and found his gaze lingering. "Speak of the devil..." he murmured.

Clustered around another locker about half-way down the hallway were three girls, slightly younger than Dave and Danny. One was a black-haired human, looking especially shy, leaning against an un-tended locker and looking down at her feet when not being spoken to by one of her companions. The tallest among them was a lynx, who was currently bent over, sorting through her locker the same as many of the other students around them. But the third, the one who had caught Dave's eye with her happy laughter, was a slender feline, backpack firmly on, a nice skirt showing off her shapely legs and the brown, patterned fur that was the hallmark of the Maine coon breed. She was, in his eyes, the most beautiful girl in the school, perhaps the world, and in fact was the previously-alluded-to girl of David's dreams, with whom he had started a secret romantic relationship.

She was also Dave's younger sister, Kelly Parrish, which explained the 'secret' part.

Suddenly, Danny's voice cut through the fog of adoration that clouded Dave's mind. "What was that?" he asked, "Didn't quite catch that." Suddenly averting his eyes, as if anyone in all the commotion of the end of a Friday would notice one student gazing lovingly at a member of his family, Dave coughed, hoping his blushing wasn't too visible. "Uhhh, nevermind, Dan, just thinking out loud," he said. Glancing down the hallway beyond the love of his life and two of her friends, Dave noted that the athletics hallway next to the gym, which was located at a right angle from this one, opposite the atrium, was totally deserted. "Hey, wasn't there gonna be a football game or something today?" he asked. Danny leaned back, still on his heels and shrugged. "No, man, the football team's going to a game at another school, don't remember which one," the rabbit said, pushing one of his floppy ears away from his face. After a second, the lapine gave his friend an odd look. "Since when do you have the slightest interest in the school football team, anyway?" Danny asked. Dave snickered and grinned quite genuinely. "Oh yeah, I'm way into school spirit," he said, then followed it up with the flattest, least enthusiastic "Gooooo Argos" anyone had ever uttered on school grounds. In truth, there was a plan now running through his mind, and it had very little to do with Danny. "Uh, listen, we're still on for tomorrow," said Dave, "but I've just remembered something I've got to ask Kelly about before we leave, so I should go catch her before she wanders off with her friends." Standing up with his bag and following Dave's gaze to the group of girls, Danny nodded understandingly. "Sure, sure. Convenient that that fine lynx's locker is right over there," Danny said, his eyes unsubtly tracing the curves of the girl's rear as she bent over again to pick up her backpack. "I've got a bunch of homework to do tonight anyway, didn't want Mom nagging me about it while we're gaming tomorrow." After Danny closed up his locker, he and Dave shared another fistbump, and Dave wished him luck. Then, as the rabbit turned to go wander out the front door of the school, Dave turned further down the hallway, carefully working out exactly how to word things. This was going to be tricky.

Walking up, he turned his smile down to medium and greeted his sister in what he hoped was a perfectly ordinary, brotherly way. He admitted he'd lost a bit of perspective since he fell in love with his only sibling. "Hey Kels. Ladies," he opened, nodding to the lynx, who'd noticed his approach as she stood back up. Kelly turned to face him, and Dave found himself rather enjoying the split second where her face just lit up with that beautiful smile of hers, before she, like him, dialled it back a bit and tried to look proper in front of witnesses. "Hiya Davey," she said, "what's up?" The lynx girl, Kelly's friend Barbara Murphy, nodded politely to the black cat. "Hey," she said, simply, acknowledging Dave. The two of them hadn't interacted on many occasions, so they didn't have much to say to each other. Dave was pretty sure Danny had asked her out once and been shot down, but that was his only connection to Barb outside of her being one of his sister's best friends. The human girl, Chelsea something, on the other hand, was newer, been living in town less than a year, and Dave barely knew anything about her. She said nothing, if anything she shrunk a little bit more into herself, blushing and avoiding looking at Dave for some reason. He shrugged it off and looked back to his sister. "Sorry to interrupt," he said, "but Ms. Grayson said she wanted to talk to you. Something about studying anatomy next week, I think." Kelly's ear twitched to the left, and her facial expression darkened for just a second, but she quickly recovered, smirking at her brother and shaking her head just slightly, in an endearing oh, you kinda way. "Oh yeah?" she asked, sounding pretty sincere, "I have been trying to talk to her about my biology grade, I'd better come check it out. You girls don't mind, do you?" "Nah, go ahead, Fluff," said Barb, gesturing dismissively, "Chels and I were gonna go meet Nina and watch bad movies at her place. Hamsters have the best snacks, it's a proven fact." Chelsea just nodded vaguely, staring at her shoes with an intensity normally reserved for prison guards watching for signs of trouble amongst inmates. There was something oddly familiar about Chelsea's behaviour, but Dave couldn't quite put his finger on it. Besides, his mind was occupied with other thoughts, and seeing that his plan was working, he held an arm out, gesturing down the hall, and walked with his sister away from her friends.

As the siblings walked away, Dave glanced back and saw that Barbara and Chelsea were leaving, Chelsea acting embarrassed and Barbara laughing about something, though the important thing was that they were heading the other way, and not towards the Parrishes. Gently grabbing his sister's arm, he led her past the door that lead to the corner stairs and nodded in the direction of the athletics hallway. Now well out of hearing range, Kelly shot her brother a Look, though her grin never faltered. "Dav_eeeey_, you said you weren't going to use that line anymore!" she complained, "Every time you talk about 'studying anatomy', you make me all paranoid that someone's going to know!" The Maine coon sighed exaggeratedly, then gave her lover a sideways look. "We're studying evolution in biology, not anatomy, and Nina's in my class," she said, poking Dave in the arm, "What would you have done if she'd been there to call you on your stupid joke, smarty pants?" "Why, I would have dazzled her with my rugged handsomeness and told her about the extra credit you were working on," he replied, winking as she giggled. "You're incorrigible," she said, in no way sounding like that was a bad thing, "So you wanna let me in on where we're really going? I doubt you're taking me to watch football practice or something." Dave grinned at her and gestured to the darkened, empty office on the corner that the athletic faculty shared separately from the rest of the campus staff. "As it happens, actually," he said, trying to sound suave, "I've been informed that the football team is away and thus the locker rooms are to be free of... interruptions." Kelly snickered and rolled her eyes, but he'd known her long enough to see that she meant it light-heartedly. "Oh my, the locker room," she said, pretending to swoon, "Golly, Davey, you spoil me with these expensive, high-class dates. Is that really the idea? If you just wanted to -" she suddenly cut herself off and looked around to make sure they were really alone. "...If you just wanted to fool around," she said, in a lower voice, "we could just go home, why the school locker room?" Dave grinned and came to a stop, as they had finally reached the matching doors to the men's and women's changerooms. "Maybe I should have been more specific. I don't really care about the locker room as much as I do... the connected shower room." As Kelly giggled, tail flitting back and forth in excitement, he winked at her. "What do you say, babe? 's been a long day, I could use a nice, hot rinse..."

Now onboard, Kelly quickly suggested they use the girls' locker room, as it was probably cleaner, and Dave found no reason to argue. Stepping inside (and locking the door behind them, as they weren't feeling that crazy), the Parrishes took stock of the room, which was painted a bright, garish pink with faded paint that could use a touch-up, and a large, equally faded Stanton Argonauts logo that was presumably meant to be inspiring. Setting his backpack down on a bench, Dave noted that there was no ancient gum stuck to the lockers in here, that the floor seemed less bacterial, and that not even one of the locker doors was missing. The Argonauts logo was also on the opposite wall from where it was in the boy's room, but that wasn't really related to his more important observations. He nodded to himself, smirking. "Huh," he muttered, "It is nicer in here." He quickly found himself blushing, however, as he glanced into a nearby garbage can and saw the unmistakably feminine proof-of-life of a discarded tampon, though his mind was quickly taken off of such things as his sister embraced him from behind, hugging him tight and nuzzling against his back. "Mmmm, Davey," she said, already purring quietly, "you couldn't have picked a better day for this, my classes were so boring and my mind kept wandering to you... I'm gonna be honest, if you hadn't done this I would have jumped you as soon as you got home." She loosened her grip long enough for him to turn around and return her hug, laughing softly as he leaned in to kiss her. When he broke it off, he began running a hand up and down her back, holding her close with the other. "You know," he murmured, "I like a girl who shows initiative like that." Kelly didn't say anything, and he realized she was opening his fly. As she slid a delicate, white-furred hand into his pants, he chuckled, grinning even wider. "Make that, I love a girl who shows initiative like that..." He sucked in a hissed breath as his sister's delicate fingers worked their way into the 'sleeve' of his boxers and then made a beeline for his genitals, biting his lip as Kelly took hold of his flaccid penis and began to gently knead. "Hello, Little Dave," she said, sounding absolutely delighted, "It's been a while since I got to feel you all soft and cute like this, hasn't it?" Despite his best efforts to get her to stop, Kelly still took a great deal of amusement in talking to her brother's manhood as they began foreplay. Even as he reacted to her touch, beginning to twitch and grow in his sister's warm grip, Dave couldn't help but shake his head with a smirk. "Just out of curiosity, Kels," he asked, "what exactly would you do if my dick talked back for a change?" Kelly looked up and gave him a Look, but it was undermined by her giggle. "Well then," she answered, "I guess that would make it a threesome." As she continued to rub and tease at his growing flesh with her fingertips, she knelt down and began to nuzzle against his groin through his pants, her enthusiasm easily matched by her eagerness. Seeing her adoration for him, Dave leaned back, seeking something to lean against, as his knees were beginning to feel weak. "God, Kelly, you're really getting into it..." he murmured, unable to take his eyes off the spectacle, "I - I think we should get undressed, though, unless you're planning on making me come in my pants." He'd said it as a joke, but as Kelly paused in her stroking and looked up at him, he swore from the look in her eyes that she was actually considering the idea. In the brief silence that followed, Dave asked himself if he would just stand there passively and let his sister make him cream his jeans... and was unable to come up with an answer. Fortunately for him, she finally grinned and stood up, releasing her grip on his cock, if a bit reluctantly, moving her hands to his belt as she leaned in to kiss him again. Leaving her hands to do their work, Dave reached up and simply let his rest on her sides for the moment as he enjoyed the feeling of her tongue against his.

Dave let himself get lost in the moment, but when he felt his pants become loose and start to drift down his thighs, he leaned back, moving to return the favour. Roughly tugging Kelly's shirt out of her skirt, he moved to the zipper that kept it intact and worked it down, slipping the skirt off of her as she pulled down his boxers, exposing his cock to the harsh light of the locker room; it was at half-mast and rising, and just as light grey as the rest of the skin on a black cat's body. Dave wanted to make off with her shirt, but found he had to stop her from continuing her dalliances with his pants halfway off like that, lest he lose his balance and fall down. Hurriedly stepping out of his jeans and underwear, turning one of the pant legs inside out in his rush, Dave stepped forward to kiss his lover again, even as he reached behind her to unclip the fastener on the rear of her panties that kept the garment closed above the hole for her tail. He hadn't noticed her opening the similar snap on his own underwear, but then Kelly's reflexes, Inherited from their feral feline progenitors, were technically slightly superhuman, so he was rarely surprised when she managed to do something more quickly and subtly than he did. Instead of immediately pulling her panties down, Dave cheekily pushed his hand under the waistband, giving her butt a spirited groping before pushing his hand beneath her and cupping it over her treasures from behind. Kelly let out a surprised noise into the kiss they were sharing, eyes fluttering open at the unexpected, but not entirely unwanted feeling of her brother's fingers playing over her warm, moistening lips. Dave didn't linger there long, merely wanting to tease her, though in truth, he sometimes felt that he could spend the rest of time just playing with his sister's body. With a farewell caress of the hood that protected her clitoris, which had yet to emerge, he pulled his hand free of her underwear and moved both his hands to lift the hem of her shirt over her head, leaning in as he tugged the shirt up and off to kiss the supple curve of her stomach. Kelly giggled softly and brought her hands up to cup the back of his head, even as he continued to move northward, dropping the shirt on the bench next to them and then bringing his hands around to her back, to work on the latch on the dark blue bra she was wearing. He still found the garments difficult to work with, but a few seconds of focusing on his task brought him victory, and soon he had the latch open and was able to free his sister's girls from their confinement. As he moved up to kiss and nuzzle at her breasts, Kelly began to scratch behind his ears. "You see?" she asked, playfully, "I told you you just needed to practice."

For a few moments, Dave focused entirely on licking and suckling at Kelly's nipples, his hands gently kneading her breasts and teasing and tweaking whichever nipple his mouth wasn't attending to at any given time. The Maine coon's purring grew louder as he tended to her; she didn't need to put her appreciation into words. To his surprise, though, after a short while she pushed him away from her chest, and Dave looked up in dismay, unable to keep his ears from folding back in disappointment, unable to look away from those firm mounds and pointy nipples, still shining from the saliva he'd lovingly bathed them in. He was just about to whimper with need, wanting more than anything to continue pleasing the vision of feminine perfection who stood before him when she reached forward and grabbed onto his shirt, which in his haze of lust he'd actually forgotten he was wearing. "Might seem a little suspicious," she said, "if you walk out of here with a soaking-wet shirt on, Davey." Without saying a word, Dave glanced down towards Kelly's own shirt, which was mostly white, and then let his eyes dart towards the showers, where - "Don't even think about it," she said, sounding more worried than intimidating. He grinned at her, glancing down at her bust once again. "...Did I ever tell you, little sister," he said, unable to hide the playfulness in his voice, "that even before I started messing around with you, I preferred girls with boobs your size? Of course, there's nothing wrong with being stacked, or having a flat chest, I mean those girls can be good-looking too, but there's something about having that perfect handful that really revs my engine..." Blushing, Kelly self-consciously crossed her arms over her girls, as if she wasn't used to the black cat leering at her this way. "I - I'm glad you like them, Davey, but I don't feel like showing them off to the school!" Shaking his head with a smile, Dave held up his hands in surrender. "I'm kidding, I'm kidding," he laughed, "I just wanted to see you blush is all. That kind of perfection, I wanna keep alllll to myself." His smile was only slightly weakened by the well-deserved punch to the shoulder that followed.

After that, Dave needed to get his lover back in the mood, so he took her hand and gently pulled her down with him as he sat down on the bench, setting her down in his lap. She shivered and giggled excitedly as she felt his erection press against her rump, settling in to hot dog her brother's rigid prick between her buttocks, the thin material of her panties the only thing separating her from Dave's hardness. Leaning in, Dave kissed along his sister's sensitive throat, her giggles quickly giving way to sighs of pleasure as his hands reached forward, not to embrace her, but to gently lift one of her legs, slowly, almost sensually tugging the sock off her foot, and repeating the gesture on the other side. Meanwhile, he took advantage of the uniquely feline trait of exchanging pain for pleasure as he leaned back enough to nip and tease at the loose skin at the base of the back of her neck. "Mmmm..." she sighed to herself, "Damn, big brother, you've never made taking off my socks seem so sexy before." He parted his lips, not to speak, but to let his own purring sound off louder in the room. They weren't quite there yet... After a moment, he kissed behind her ear and chuckled. "You make it so easy, sis," he whispered to her, "Even your feet are beautiful." As one of his hands cupped itself over one of hers, lacing their fingers together with a squeeze, the other wandered down towards her inner thigh and began to trail a finger up and down just outside of the area covered by her underwear, occasionally teasing his nail under the fabric, but never close enough to make contact with her slit. "Oh, Kelly... I could just touch you all day..." he whispered, enjoying the shudder that ran down her spine, "Actually, yeah, I don't have anything to do this afternoon, what do you say we get dirty before we get clean?" Whimpering at his touch and her own clearly growing need, Kelly swallowed before answering. "Oh - oh God, I'd love that so much..." she murmured, pushing back against her lover's hardness, "but - I'm sorry, Davey, I don't exactly bring condoms to school with me, we don't have protection. Ohhh..." She moaned quietly as he finally moved his hand to where she wanted it most, gently resting on her pelvis, cupping her almost possessively, one extended finger beginning to tease up and down her slit through the panties, which immediately began to darken as her arousal soaked into them. "I know, baby, me neither," he purred into her ear, "I was thinking something a bit more mathematical, since we're at school, hmmm?" She giggled, though even her laugh was tinged with need. "Y-you mean a - a sixty-nine, don't you?" she asked, her voice barely above a whisper. "Mmm-hmm," he confirmed, nuzzling against her blushing cheek, "Nothing too elaborate, I'll just lie down on this here bench and you take your beautiful self and -" To his surprise, she cut him off, groaning somewhere between desperation and frustration as she did so, grabbing hold of the hand that endlessly teased her and holding it down, preventing his fingers from moving. As much as he enjoyed the way her squirming felt against his manhood, this was not the reaction he'd expected. "No, Davey, we can't..." she moaned, "If you - if you come before we shower, we'll have to wait for you to, um, recharge or whatever you call it... we'll be in here for ages. What if the janitor tries to come in here to wash up? Even if he d-doesn't see anything, it probably looks really bad for the two of us to be locked in here alone..." Turning her head to look him in the eye, she pouted adorably. "And I wish you would stop getting me so worked up while I've got my panties on, I've got to walk out of here wearing these, you know..." She managed a smile. "You know, considering how many times you've denied it, you sure act like you've got an underwear fetish..." Suddenly Dave was the one blushing, and he pulled his hand away as she giggled. "You - I don't..." he mumbled, before coughing and changing the subject, "Okay, we can skip the sixty-nine, you raise a pretty good point." He couldn't resist pinching her through the thin fabric, enjoying the way she yelped and jumped slightly. As she turned to frown at him, he winked at her. "Next time." Despite the pinch, Kelly laughed at that, raising her eyebrows as she regarded her lover. "What, next time we're in an empty locker room all by ourselves?" she asked, her tail twitching in amusement, "I don't know how often you expect this situation to come up, Davey, but alright..."

With that, Kelly got up off her brother's lap, smiling as he immediately tugged her sodden panties down, and giggling as his hand darted out to tease against her treasures as she lifted one leg, then the other to step out of her underwear and free herself from the last of her clothing. When she turned around, Dave hurriedly tugged his socks off to join her in nudity, and she extended her hand as he got up, enjoying the feeling, however silly they might look here, as they walked hand-in-hand to the showers. Dave noted with a fair amount of appreciation that this area was significantly less grody than the boy's shower room (a place that made him thankful his only exposure to it was after gym class), and paused a moment as Kelly stopped to ponder the various shower heads. "Hmmm..." she muttered to herself, "that one never has hot water, but that's near the beginning of the day, maybe it's got some more now? And that one has crappy pressure, just forget about it. Maybe the corner, we could lean in and get support..." Dave, for his part, was silent, knowing absolutely nothing about the quality of the different showers in this room, and was biding his time by leaning back and checking out his sister's butt, currently accented by her fluffy tail swishing back and forth as she concentrated on her decision. Finally, she suggested a shower to the right, and Dave walked up with her and turned the water on, both Parrishes instinctively stepping out of the way as the cascading water came out frigidly cold at first. Dave hesitantly stuck a hand into the flow, waiting for it to warm up, and when the chill had worked its way out, he grinned at his sister, and they stepped under the flow together, embracing immediately and just standing there, directly in the middle of the downpour as they kissed and ran their hands over each other. As Dave took one of her buttocks into his hand and gave it a nice firm squeeze, Kelly broke off the kiss and sighed happily, reaching up to move her long, brown hair out of her eyes. "It sounded so stupid," she murmured, "but I've gotta hand it to you, Davey, this was a great idea. We - Aah!" As she cried out, the fluffy female arched her back, pressing her breasts against her brother, as Dave's hand suddenly moved slightly northward, coming to rest on her lower back, just above the base of her tail, where he immediately began to scratch at the skin with no more intensity than he'd use to scratch behind her ears. Blushing, ears lowering, Kelly shuddered in his arms, biting her lip in that way that always made Dave suspect she was swallowing a moan. "N-no fair..." she whimpered, suddenly hunching over and pressing her cheek against his chest, nuzzling with a bit more force than usual. At the same time, she began to shift her feet around, unable to sit still for long.

"Oh God..." she gasped to herself, beginning to rub her thighs together. It wasn't exactly a secret that for feline females, whether morphic or not, the skin just past the base of the tail was a powerful erogenous zone; Dave had once watched a video of a particularly sensitive mountain lioness who (supposedly) brought herself to orgasm while fully clothed just by scratching herself there. Just placing your hand there on a feline woman was considered an extremely forward gesture, and would probably be considered sexual harassment if you weren't in a relationship with her. "Nnngh, you always go right for the spot, D-Davey, it's meeeean..." she moaned, her grip on his body tightening. He couldn't help but notice, though, that she had made absolutely no efforts to make him stop, so of course the only real reason she was complaining was that she was embarrassed, like so many other things, by how quickly 'the spot' got her turned on. Suddenly she pulled back and lunged forward, teeth bared, and closed her muzzle around her brother's shoulder. Dave flinched, but he didn't move; she barely put any pressure down, and what pinpricks he did feel were pleasurable to his feline physiology. It was a phenomenon called 'happy biting', when a feline expressed pleasure or happiness by nipping lightly at whoever was making them happy. Morphics, as a general rule, suppressed the instinct, finding it particularly uncivilized (and potentially painful if they got carried away), but sometimes, if they were feeling particularly safe and relaxed, and felt strongly enough towards a person, they would let it slide. Increasing the pressure of his rubbing, enjoying the unashamed moan of pleasure Kelly let out, Dave grinned, his fangs showing. "It's the video games' fault, sis," he said, "I've been trained my whole life that if something has a weak point, you go there first." Yowling with need, Kelly finally snapped her hand around behind her and grabbed her brother's wrist, pulling it away from her tail-base. He was expecting to be scolded, thinking he'd gone too far. "Enough, already, you've got me all hot and bothered!" she cried, desperation in her eyes. Dave's own eyes widened, and he grinned hungrily, as she brought his hand around in front of her and pressed it between her legs. "C-come on, Davey, I need this..."

Dave shivered, intensely aroused by his sister's blatant display of desire. Normally he had to tease her and play dumb as to what she wanted in order to get her to say things like that, so when she came right out with them, she really meant them. Swallowing, he leaned forward, holding her tight against him, enjoying the feel of her wet, though still soft fur against his aching, ignored prick. Though clearly, not as much as she enjoyed the feeling of his fingers boldly pushing past her labia and into her tight, wet heat. "Oh God!" she cried out, not even trying to hide her arousal, pushing back against her brother's fingers as he traced them along the contours of her vagina, friendly and familiar after all the time they'd spent together, and yet still so very, very exciting. "D-Davey, m-my..." she trailed off, grinding against his hand, looking into his eyes and whimpering. This seemed much more characteristic of Kelly Parrish's behaviour. He had a feeling he knew what she wanted, though, and extended his thumb, laying it squarely on her clitoris. Sure enough, Kelly gasped and held him even tighter, moaning gratefully as he began to tease and stroke at the sensitive nub while his fingers continued to probe her velvety depths, growling with desire as he felt her walls clenching down on his fingers appreciatively. As he continued to work his sister's pussy, Dave noted that, as ever, it felt different when they were standing under the water like this. For one, it was impossible to tell if he was sweating or not, as the liquid was already running and dripping across his entire body. It even prevented Kelly's juices from soaking into the fur of his hand, though the intoxicating scent of her arousal still filled the air, making him want her so badly he could taste it. Suddenly, the mewling female's knees buckled, and Dave shot his free hand down to catch her, grabbing hold of her butt in the process and lifting. Naturally, his 'occupied' hand slipped out of her as she moved, and he held her firmly to make sure she was okay, but she just blushed and grinned. "Guess you're doing something right, eh?" Kelly said, shrugging. She reached forward and took his hand, encouraging him to return it to her love tunnel. "C'mon, Davey," she pleaded, "Don't stop now, I was starting to get close... I promise I'll return the favour! Um, you can even, you know... shoot it on me if you like... you know, since we're in the shower anyway..." Despite this unusually generous offer, though, Dave, was distracted, looking down her body towards his other hand. As he'd grabbed her butt to keep her from falling on it, his middle finger had brushed against something under her tail, which had begun to fill his feline mind with devious ideas.

As his sister reached for his erection, Dave stepped back, taking hold of her wrist. To say she looked surprised by this reaction was an understatement. "D-Davey?" she asked, "Don't you wanna...?" she indicated his groin, as if he'd have forgotten what she was talking about less than ten seconds earlier. When he stepped forward again, he kept going, pushing her gently against the wall - and pushing his stiff penis against her belly, contact which traditionally really turned Kelly on. "I actually had something a little more involved in mind than just using our hands, little sister..." Dave explained, chuckling quietly. He noted their purrs; almost there, but not quite all the way yet. Kelly pouted and turned her head away as he leaned in, avoiding his kiss with a frustrated groan. "That's not faaaair, Davey, you know we don't have any condoms, and I hate it when you try to make me want to take the risk!" she said, sternly, sounding a heck of a lot more responsible than her brother. Suddenly she frowned, giving him a questioning look. "Wait a minute," she muttered, "You haven't tried to do that in forever, you've been really good about the condoms... you even pushed me off when I came home drunk after Nina's party last month and tried to climb on you without one. What are you really trying here?" Stepping back, Dave burst out laughing, shaking his head. "Damn," he murmured, sounding not-at-all displeased, "I didn't think you'd see right through me like that." He reached forward to stroke the backs of his fingers against her damp cheek, though she still looked at him somewhat suspiciously as he continued. "Sorry, Kels, I shouldn't play games like that," he apologized, "I was gonna get you even more hot and bothered, really want to go all the way, and, uh..." Dave shrugged self-consciously before he continued. "...I was gonna suggest we could try anal instead." Instantly, Kelly's cheeks, which had begun to lose their flush, turned beet red, and her ears swiveled around back, though they didn't quite flatten to her skull. "Anal? What happened to 'maybe on special occasions', huh?" she asked, crossing her arms over her chest. He winked at her. "So, what, our first time doing it at school isn't a special occasion?" he asked. Kelly said nothing, but her expression made it clear she wasn't buying it. "Oh, come on, Kels, please?" he begged, shamelessly, "I'm way more worked up than I thought I would be, I - I need something more than just hands!" Kelly's arms remained cross, but her face softened a little. "Hmph... does it have to be in the butt? What if I, you know, used my m-mouth on you?" she suggested, "I'll even swallow your stuff this time, if you want." Without saying a word, Dave put on the Sad Kitty Eyes that his species was blessed with and he was especially good at, his lip quivering, his ears lowering, and his whiskers twitching adorably as he looked forlornly at his lover. Kelly put on a smug grin and huffed at him, her breath scattering water droplets as she did so. "Well, even if I did want to let you, um, do that," she said, "it's not like I bring lube to school either, and I'm sure as hell not going to let you under my tail with nothing but water." Dave's facial expression evaporated, replaced with a frown. Crap. He hadn't considered that. Quickly turning around, his eyes darted back and forth across the locker area, as if he could see through the containers with X-ray vision, desperate to find something, anything, that could ease his sister's discomfort in such a union. As he left the warmth of the shower and walked, dripping, to the locker area, his lover sighed. "Come on, Davey, do you really expect to open one of those things and find a tube of K-Y?" she asked, gently, not patronizingly, "Even if we lived in a porno movie, this is the girls' locker room, all the lube would be next door." For a second, just one fleeting second, Dave considered dashing over to the change room next door, before he realized how insanely stupid that idea was and groaned quietly. He searched each locker, finding nothing useful; one held a single sock, another had the discarded wrapper from a chocolate bar, a third held the crumpled packaging for the morning-after pill, worryingly, but most of them were completely empty, save for dust. Finally, at the second-last locker, he found a plastic tube, and held it up triumphantly even as he shivered from the cold. "Aha!" he cried, catching Kelly's attention again. She'd gone back to focusing on the shower in hopes of encouraging her brother to come back, but now she looked at him disbelievingly. "WTF?" she said, spelling out the acronym in a verbal habit that normally made Dave cringe. Right now, though, he found he didn't care. "You actually found a thing of lube?!" she asked, incredulously, "Did you, like, place it there before we came in here? Is this a set-up, Davey?" He shrugged as he walked back over, looking down at the tube. "Man, I wish I'd thought of that," he muttered, "No, looks like this is skin lotion, I guess a human girl must have left it there. It should still work, though! Uhh, at least I think so..." Kelly giggled at his obvious excitement, and sighed dramatically. "You know what?" she said, touching his cheek with a smile, "Since it clearly means a lot to you, and you actually managed to find something, let's give this a try."

The fluffier of the two (though it was hard to tell, given how wet they both were) giggled as her brother's face lit up with glee. Stepping out of the spray of the water, she rolled her eyes, though her grin didn't diminish any. "Boys. What are you gonna do?" she asked, semi-reluctantly turning around and raising her tail. Dave shook his hands to try and rid them of as much water as he could, with the stubborn substance clinging to his fur. That accomplished as best he could, he squirted some of the pleasant-smelling cream onto his fingertips, and reached forward, gently pressing his fingers against his sister's anus. She immediately stiffened and yelped. "Ahh! That's really cold..." she muttered, shivering. "Sorry, Kels, it'll warm up, I promise," he replied, as he began to massage the cream into her flesh, "I mean, how could it not? It's you, after all." She snickered at his blatant flattery, though it sounded a little forced, which was understandable. He tried to work both thoroughly and quickly, and soon, after getting more of the cream, started applying pressure, his fingers pushing into his sister's tight rear and smearing the lotion against her walls as she whimpered. Turning her head over her shoulder, and yet not actually looking at him, Kelly blushed as she asked a question quietly, barely loud enough to be heard over the water they were wasting. "Oh Davey... last time I spent all that time getting myself, uh, cleaned up inside. What if..." she trailed off, and unlike most times when she had to say something embarrassing, this time she closed her eyes tight and just shook her head, unable to bring herself to say it at all. This was fair, given that Dave didn't particularly want to think about it himself. As he continued to prepare her, adding another finger to help her muscles relax, he leaned in and whispered to her. "Don't worry, little sister, we're already in the shower. Even, er, in the worst case scenario, we just get cleaned up and pretend nothing ever happened." Making direct eye contact again, she grinned shyly, and then looked back at the tile wall as if searching the grout for mildew. Deciding that his sister's backdoor was as lubricated as it was going to get, he pulled his fingers out and switched hands, squeezing a generous dollop of the skin cream into his palm before gripping his cock and rubbing it up and down. He suppressed the urge to moan, surprised at how nice it felt as his hand glided up and down his shaft, working the lotion in. Maybe the humans were onto something. In any event, it didn't take long for his prick to get nice and slick, so he dropped the tube at his feet and leaned forward. "So, I'm gonna put it in here so the water doesn't wash the stuff away," he said, "and then we can sort of, uh, shuffle back into the water, okay?" Kelly grinned back at him, but she looked nervous again. "Okay, Davey," she agreed quietly, "G-good thing there's no one else around, we're gonna look real silly." Stepping in close behind her, Dave took his manhood firmly in hand, lined it up with Kelly's rear entrance... and hesitated. After a moment of that minute touch, with no pressure, Kelly looked back at him once again, probably expecting him to want her to beg for it, but instead she found him just staring at the point of their impending union with an uncertain look on his face, biting his lip. "What's wrong?" she asked, quietly. "I - suddenly I'm not so sure about this," he admitted, "I mean, this is skin cream, it isn't really meant to be used as lube, and we've only done it the one time, so, uh, so what if it hurts you? M-maybe you were right the first time and we should just use our hands..." As he glanced back down at his erection, which he could feel slowly losing its stiffness from his anxiety, Kelly took a hand off the wall and reached back, gently taking hold of his wrist. He looked up at her face and was somewhat surprised to see such a warm smile there. "Come on, big brother," she said, softly, "don't chicken out now, I had just talked myself into this, I was gonna enjoy it too... and besides, you've earned it." When he continued to just stand there, she began to wiggle her butt back and forth, her tail flagging high and swishing back and forth enticingly, though it flicked water onto the floor with every flick. "You know I'll tell you if it hurts or I want to stop, right? Just relax, Davey, you aren't going to break me. If the lotion just doesn't work we can just try something else." Finally relaxing, Dave grinned at her behaviour and placed a hand on her rump, getting a nice feel of her soft buttock, and felt himself returning to full hardness as she purred louder at his touch. Lining up his prick with her tight entrance once more, Dave winked at his lover with a smirk. "You always know exactly how to get me going, little sister..." he murmured, "You asked for it, so here goes nothing!"

Kelly hurriedly turned back around, bracing both of her hands against the wall as Dave began to apply pressure to her backside. Nowhere near as much as he'd use during more normal lovemaking, but then there was far less resistance, and far more experience, in that department. Kelly tensed up, which didn't help matters, but after a moment, she relaxed, leaning in to prop her forearms against the wall, as if she needed more support, pressing her cheek against the cool tile, eyes closed as if mentally preparing herself. Just like the last (and only) time they'd done this, there was absolutely no progress for the first short while, but Dave patiently kept it up, increasing the pressure slowly. The feral part of his brain knew (and kept reminding him) that he could overcome this resistance and get inside her right now if he just rammed it in as hard as he could, but Kelly might never forgive him, and if she was sore in the morning, he'd never hear the end of it. Finally, he felt the stubborn ring of muscle begin to yield, spreading as the head of his prick pressed slightly deeper, and Kelly shivered and made a noise somewhere between a moan and a whimper. She tensed up again, and Dave leaned forward (carefully making sure the movement didn't transfer to his hips) and licked her cheek before whispering in her ear. "It's okay, little sister," he said, softly, "Remember, I love you twice." Kelly grinned ever-so-slightly, her muscles relaxing, though her eyes remained clenched shut as she answered, her voice slightly strained. "I love you t-too, big brother... both ways." Dave lifted a hand from her hips and placed it over hers on the wall, cupping it gently, and he took a deep breath and pressed even harder. Kelly shuddered and moaned quietly as Dave finally managed to overcome the ring of muscle altogether, burying his stiff cock in his sister's rump, inch by inch, her warm inner walls clenching down on him even tighter than he remembered. "Oh, K-Kelly..." he whispered, trying to keep his movements smooth. She gasped as he pushed just a little too hard, responding by clenching down on his prick so hard it nearly hurt him, and he stayed right there, kissing her cheek and murmuring encouragement to her about how well she was doing. It wasn't until he gave her hand a squeeze, though, that she sighed and he felt her stop trembling. Pressing forward once again, he didn't stop until his fuzzy scrotum brushed against her buttocks, and he was fully hilted in Kelly's rear.

Kelly panted slightly with the decidedly contradictory exertion involved in relaxing her muscles, and Dave leaned forward to kiss her neck again. "There we go," he said, "How're you feeling?" She opened her eyes and looked back at him, blushing. "L-like I've got my brother up my butt," she replied, her voice sounding a little strained, "I think I'll b-be okay... kinda wondering why I talked you back into this, though..." Despite her words, she had forced a smile onto her lips, and he chuckled as he nuzzled against her, reaching his hand around to lay it on her belly, where he began to rub, up and down, encouraging her to purr, stopping just before he reached her treasures on the down-strokes. "Maybe it's because you love your big brother, and want to make him feel good," he said, playfully, "or maybe it's because you remember that last time, I made sure you walked away as satisfied as I did." As he said these last words, he let the tip of a single finger graze her sensitive clitoris, and enjoyed her sharp intake of breath. "Nnngh, Davey, don't tease me..." she moaned, writhing against him, "please, if you're going to - to play with me, just touch me, I already let you under my tail, don't be mean..." Dave had to admit she had a fairly solid point there. "Okay, babe, I'm just funning around," he said, "Let's move under the water so we can get started, okay? No more teasing, I promise." With that, he leaned forward to kiss her cheek once more, and then focused on a much less dignified task. Moving his hand back up to her stomach, to try and hold them in the same relative position, Dave carefully extended his leg and took a step. "Ready, Kels?" he asked. She said nothing, but nodded, and soon, they were both awkwardly shuffling across the floor towards the water, both of them snickering and giggling as they went at the unseemly display they were putting on for the benefit of the shower room. Finally, they'd reached the water, Dave still firmly buried in Kelly, and they both stood up straight to let the warmth cascade down their shivering forms, washing away the cold and restoring their energy for the lovemaking to come. When they were properly warmed up, Kelly reluctantly leaned out of the direct spray of the water, against the wall, resuming the position she'd been in before. Enjoying the feel of the water running down his back, Dave thought about angling the showerhead to spray between their bodies so Kelly could get in on that warmth too, but then worried the water would wash away the skin lotion on his dick when he pulled out. Putting theoretical worries out of his mind, he told his sister to prepare herself, then slowly drew back until only the head of his cock was still inside her, getting squeezed very tightly by her anus, which was still none too happy about his presence there, and waited a moment, giving her time to adjust to the sensation before his hips pushed forward again and he slid back into her tight embrace. Kelly's back arched slightly and she quietly moaned a long, low ohhhhh from the time he started this movement to the moment he was hilted in her again. Without pausing this time, he drew back again and waited only a split second once he was nearly out before pushing back in, shaking his head and marvelling at the sensation. And he thought her 'flower', as she liked to call it, was tight... "You - you doing okay, little sister?" he asked, starting to breathe harder as his arousal took a toll on him. She swallowed before answering, and her voice sounded even more strained than before. "Y-yeah, it doesn't hurt anymore... but it still feels so - so weird..." she said, taking deep breaths between thoughts, "I don't understand how there are g-guys who can get off to just this..." Dave paused in his thrusting there, though he hadn't meant to. He was just really put off by what she'd said. He had a vague understanding that there was some kind of gland or something in that region in men but not women, one which supposedly caused intense pleasure when rubbed the right way, but not having any interest whatsoever in that kind of thing himself, his knowledge on the subject was rather foggy. No, he had stopped because he was surprised that Kelly, of all people, had even heard of the idea. Looking over her shoulder, presumably to see why he'd stopped, his lover saw the look on his face and laughed softly even as she blushed. "Oh, come on, Davey," she said, chidingly, "I've been on the Internet too. Don't guys look at, like, lesbian porn? It's the same thing!" For just a moment, Dave was struck with dismay by the idea of his sweet little sister, his precious love, browsing the same kind of filthy pornography he'd seen online (with the exception of 'genre', obviously), and then he realized the contradictive irony of that statement, given that his erection was buried in her backdoor at the moment. Shaking it off, he gave her a weird look, but couldn't keep a smirk off his face. "Yeah, but when's the last time I talked about watching porn while we were... you know, doing it?" Smiling back at him, Kelly clenched down on his prick, and he shivered. "What was it you were saying to me earlier?" she asked, surprisingly playfully, "Oh yeah... just relax, big brother, just go with it."

Grinning back at his lover, feeling her purring beneath his fingers, Dave chuckled, and went back to the motion that came naturally, and despite the tightness and the resistance inside, he soon got into a rhythm of thrusting and withdrawing that had both Parrishes groaning quietly. As Dave increased his speed, grunting as he pushed home each time, he felt his scrotum begin to sway, gently bumping into Kelly's body, which reminded him he had more to do here than just focus on not hurting the slender feline. He moved a hand to the tuft of fur between and above her breasts, which at the moment had 'melted' into a barely-noticeable bump thanks to the dampness, and pressing there, encouraged her to stand up a little more straight, stepping forward and standing right behind her, his chest pressed against her back. "Davey?" she asked, curious, though not objecting, as to why she was being re-positioned. Nipping the back of her neck, earning himself a gasp of pleasure, Dave took his hands off her hips and moved them around to her front, lingering on her belly. "Just wanted to make it easier..." he murmured, as he pulled back and then pushed back in, "to do this with my hips." He continued thrusting into her, and, carefully waiting for a moment when Kelly's eyes were closed, he suddenly trailed his hand down her belly, leaving a flattened path along her wet pelt behind him, finally reaching the pink lips peeking out from the fur between her legs, and ran his fingertips quickly down and up her slit, flicking her love button as he reached the top. As Kelly gasped and tensed up against him, he leaned forward to nibble her ear. "...Because," he whispered, "It frees up my hands to play with your sexy, sexy body. Mmm-mmm!" Kelly whimpered, not from discomfort this time, as he began to play his fingers up and down her slit, wondering how much of the moisture he felt on her labia was water and how much was arousal. Meanwhile, his other hand moved to paw and grope at her breasts, and Kelly clearly approved, letting her head loll back with a groan as he began to gently rub and squeeze at one of her nipples . Thus encouraged, he continued thrusting into her as his fingers pressed between her lips and into her wet heat; simply by design, Kelly's vagina wasn't as tight as her rectum, but it was even hotter, and so, so much wetter, the fleshy walls totally slick with what could only be her desire at this depth. As he played his fingertips along those walls and felt her clenching down on the two fingers he'd slipped into her, he opened his mouth just enough to let his purr sound out, nuzzling against his sister from behind. "Jesus, Kelly," he whispered to her, "I wish that I'd planned all the way ahead, brought a rubber, I just love your pussy..." "Daveeeeey..." she whined, as he'd known she would. "I know, I know, you don't like me talking about your pussy," he said, pointedly, beginning to thrust a little faster, getting more worked up himself as he touched his sister's body, "But I can't help it, you're so hot and wet and alive... the first time I ever felt you clenching down on my fingers, I nearly came on the spot." That was a white lie, in fact, as that event had occurred minutes after Kelly had given him his first handjob, so he was nowhere near ready to come again, but then being completely truthful wasn't the point of talking dirty. He felt her shudder against him and moan, and he stopped talking to focus on touching her inappropriately, adding another finger to explore her depths and using his thumb to stroke her throbbing clitoris even as he tweaked one of her nipples between thumb and forefinger. As he continued this relentless assault of pleasure, Kelly resorted to mewling wordlessly, lost in the moment. It was only when she started pushing back against his thrusts that he realized even that was enjoyable to her, at least a little, once she'd gotten used to it. His own need boiling up inside, he leaned forward to nip and lick at the loose skin on the back of her neck, inhaling sharply through his nostrils to enjoy the natural scent of his sister, his lover, and throwing back his head to yowl with desire as he throbbed within her, his pre-come no doubt easing his thrusts just a little more. It was hard to hear over their panting breath and the water hitting the smooth tile floor, but Dave suddenly realized that their purring had synchronized, something that was almost entirely unheard of for their kind but came naturally to the incestuous couple every time they made love. Closing his eyes with a shudder, Dave grinned. That was how he knew they'd really hit their stride. "Oh, Kelly..." he moaned again, breathlessly, before abandoning talk altogether and losing himself in the sensations of lovemaking.

For a few minutes, they coupled in relative silence, their breath coming hard and fast, punctuated by grunts, gasps, and moans. Dave had spooned himself tight against his sister's back and continued to play with her, but he had to admit a lot of his focus was on the delicious sensation of her tight walls rubbing back and forth along the sensitive skin of his achingly stiff penis. It briefly occurred to him to wonder how much water they'd wasted, but he told that part of his brain to get with the program and start worrying about the warm, naked girl in his arms instead of the school's facilities bill. Burying his nose against the back of his lover's neck, he partook of her scent again, as if he needed to remind himself who he was joined to. "My sweet little sister..." he murmured, shivering from the indecent thrill that ran through him. She didn't say anything in response, but, apparently more comfortable with what they were doing, she moved a hand down from bracing herself against the wall and just laid it gently on the hand he was using to explore the depths of her love tunnel; she wasn't aiding or interfering with him, just touching the hand that was pleasuring her. Even though it wasn't the usual method, Dave felt just as close to his sister as he did when they were being more 'vanilla'; they could only go on 'dates' infrequently, going to the city where there'd be less chance of being seen by someone who knew them, and they had to restrain themselves from behaving like a couple when they were out in public. What they did behind closed doors might have seemed like just a perverse kink to outsiders, but making love was one of the only ways Dave and Kelly had to really express their feelings for each other, so it shouldn't be all that surprising that they did it as often as they could manage. It wasn't too long, though, before the extra tightness started to work against Dave, and he could feel his climax building up. "Nnngh, Kels... are you getting close?" he asked, ever the gentleman. Kelly tried to answer, coughed, and leaned back a little to get her muzzle in the water spray and wet her parched tongue before trying again. "N-not quite, Davey..." she managed, "but I can feel it, um, building up... Please don't stop..." He leaned in and kissed her cheek quite chastely, considering what they were doing. "Never, love," he whispered, and then slowed down his thrusts, bought himself a little more time as he really focused on fingering his only sibling.

He began to nip at the back of her neck again, playing on the pain-for-pleasure impulse as his fingers started moving more energetically, his thumb becoming more merciless as it rubbed and stroked at her throbbing clitoris. On the other side of her body, Kelly's tail began to lightly bump against Dave's side, flicking back and forth in her pleasure. Normally this would be an almost-unnoticeable thwap, but with all the water in her plush, dense fur, it had been rendered into a heavy, wet slap. Dave didn't pay much attention, though, so focused was he on his lover, who was very clearly appreciative of his efforts. "Ohhhhh, God, b-big brother, that feels so goooood..." she moaned, returning both her arms to the wall so she could rest her head against them. Dave said nothing, for his mouth was occupied behind her neck, working her loose skin back and forth between his front teeth, careful not to let his sharp teeth pierce though and actually injure her. With a groan of need, Kelly's leg began to twitch and dance below them, and Dave started to wonder if her knees were going to give out again. As he worked her love button without mercy, his fingertips sought out the more receptive regions inside her; despite enthusiasm and effort, they hadn't yet managed to locate Kelly's G-spot, but there were points on her inner walls that were more sensitive than others. Dave was now getting so worked up himself that even at this slower pace, he had to release the hold his teeth had on her in order to breathe harder through his mouth. Soon enough, Kelly was whimpering and shuddering against him, bowing her head down and moaning unashamedly; it was always when Kelly no longer got embarrassed by the noises she made that Dave knew she was really getting close. Thrusting home especially hard just once, making her gasp, Dave leaned in close to the Maine coon's ear. "Come for me, little sister," he whispered, though with his lust it came out almost as a hiss, "Come as hard as you can for your big brother."

With that, Kelly stiffened against him, every muscle in her drenched body tensing up, and with a shudder, she let out a strangled cry of pleasure, wordless but passionate, just before her orgasm exploded from within her. As she moaned in pure relief, Dave felt her inner walls clench down on his fingers, the hot flesh rippling rhythmically as if trying to draw him in further, and her clitoris began to throb, hard, in time with the spasms of her pussy. He continued to stimulate her, rubbing her clit and fingering her as best he could with the walls squeezing in on him like that, but admittedly, he was distracted by the other side of her pelvis; as Kelly came, her rear also clenched down in time with her other pleasures, meaning she was squeezing his drooling prick harder than ever. It wasn't as 'sophisticated' as it felt when she came when he was still inside her during their usual trysts, that beautiful rippling sensation that seemed custom designed to pull him over the precipice of release with her, but he couldn't deny the fact that suddenly his penis was experiencing a tightness he hadn't known was even possible, so with a growl, he began to rut his lover's backside with extremely quick, shallow thrusts, his sac bouncing off her pelvis again and again, though if this new movement bothered a quivering Kelly, she didn't complain. Before very long at all, Dave hilted himself in his sister's rump one last time with a long, low groan, closing his eyes as his own climax arrived. Instantly, his steel-hard prick began throbbing and spasming inside her in time with his grunts, spurting out thick gouts of hot, gooey feline seed that jetted forth to paint Kelly's bowels with his come. For her part, Kelly, whose pleasures were tapering off, whimpered and moaned at the sensation of her brother emptying his balls into her; for obvious reasons, the Parrishes relied on condoms far more often than not, but she often talked of how very kinky she felt when she could feel her brother ejaculating inside her. Naturally, even when that feeling was under her tail, it still made her toes curl up on the wet tile beneath them.

Soon enough, their ecstasy had come to an end, and brother and sister stood there, panting hard, leaning on each other as much as the wall for support, the soothing water replacing the usual sweat and love fluids that dampened their fur after such a vigorous lovemaking session. "Ohh... oh damn..." murmured Dave, "Kelly, that was so good." He leaned in and gently kissed his lover on the cheek, enjoying the sound of their synchronized purring. Kelly sighed contentedly and looked over her shoulder at him. She looked tired, but happy. As she smiled at him, she reached down and cupped her hand over her brother's, which was still buried inside her, as he simply hadn't thought to move it. She didn't do anything, just held Dave's hand against her as if savouring the sensation for as long as she could. At least, that's why Dave would be doing it, and that's why he hadn't yet pulled his slowly softening penis from her backside. As if she had read his thoughts, Kelly squeezed down on him and giggled. When she finally spoke, her voice was soft, calm, and very, very relaxed, if a bit tired out, and her purr sounded through in her words. This was an immensely satisfied cat. "I'm glad I let you talk me into this, Davey," she said, not even blushing as she did so, "I thought it was gonna be all about you, and I was okay with that, but once I got used to it, I actually enjoyed myself." Dave couldn't help but grin back at her, moving his free hand from her breasts to her belly, just feeling the vibrations from her purring. "Happy to hear it, babe," he said, "...does that mean we can do it more often?" Kelly gave him a Look, but there wasn't much fire behind it, and she smirked as she shook her head in mock exasperation. "Daveeeeey..." she giggled, "Come on, you aren't getting tired of - of the other way already, are you?" Dave just laughed and kissed her cheek again. "I could never get tired of loving you, Kels. Not if we did it every day for a million years," he paused for a moment, putting on a thoughtful expression. "In fact, if we could arrange that..." Kelly giggled again and moved his hands away. Dave quickly moved his fingers to his lips, placing them in his mouth and savouring the taste of his sister's juices before the water could wash them away. Kelly didn't see this as she'd turned back around, but only long enough to gently pull away from him, his half-hard cock sliding out of her backside and slapping against his scrotum. Glancing down, Dave was quietly relieved to see that it was visually spotless, but he was still going to give it a good scrub, assuming they hadn't used up all the hot water in the county by the time they finally got around to actually cleaning themselves. For now, though, he was more concerned with Kelly, as she turned around to face him and leaned back against the wall, reaching out and pulling him into her embrace so she could kiss him, deeply and passionately, the one thing that had been missing from their lovemaking. He was only too happy to oblige her and fill in the blank.

After a short time the siblings spent just enjoying the moment, enjoying each others' closeness, Dave broke off the kiss and stepped back, grinning at his sister. He looked down at his naked wrist as though he were wearing a watch, then winked at the Maine coon. "We have been in here kind of a while now," he said, "We'd better clean ourselves up and get out of here." Nodding, Kelly pushed herself off the wall and stretched, letting out a satisfied yawn as her brother ogled the effect arching her back had on her breasts. "Alright, Davey," she said, smiling back, "We might as well get out of here before they lock the doors for the night." As she stepped under the shower, Dave looked around, shrugging to himself. "I guess the girls' room doesn't have any shampoo either," he muttered, before speaking up and turning to his sister. "That's fine, though, we can just rinse off now and get cleaned up properly when we get home." To his surprise, Kelly turned and frowned at him, blushing slightly. "Davey, I can feel your stuff running out into my fur, if you think I'm just gonna leave it there all the way home, you're crazy." Grinning even wider, the black cat waggled his eyebrows ridiculously and slipped a hand out to caress her butt. She put on a disapproving face, but he knew she was secretly enjoying it; her Inherited reflexes were faster than his, so if she hadn't wanted him to touch her, her hand would have been wrapped around his wrist before it reached its destination. "Crazy about you?" he asked, leaning in for a kiss as she giggled. Instead of playing to his advances, she suddenly leaned in, playfully licked his nose, and stepped past him, stopping just outside the reach of the showerhead. "Wouldn't have you any other way," she replied, grinning back, "Just a sec, big brother, wanna get nice and clean before we leave." Dave watched her go, confused to the point where he only briefly leered at her butt before frowning slightly. "Where are you going, Kels?" he asked, "There isn't even any soap here. Come on, we'll be fine." The Maine coon shivered, crossing her dripping arms and holding them close to her chest as she hurried towards their things, still piled on the benches. "Davey, forget just feeling gross," she said, raising her voice slightly to be heard across the room, "if we don't clean ourselves properly, someone could smell us on each other before we get home." That didn't really answer Dave's question, so he started to protest this as she opened her backpack with trembling hands. "But - " was as far as he made it, as she quickly produced a bundle wrapped in a plastic bag. "Aha!" Kelly cried triumphantly, reaching in and fishing around. Catching a glimpse of the team logo of the Andrew Stanton Argonauts, Dave realized the bag contained his sister's gym clothes. She pulled out a light pink plastic bottle with a silhouette of a woman standing seductively next to a logo he couldn't quite read from this distance. "Come on Davey," she said, grinning at him, "a girl's got to be her best even at school; I bring this with me on gym day. Now we can wash off all the evidence!" Dave found himself blushing slightly, stepping back as she walked up. "Aww come on, Kels," he protested, "you always get the girliest-smelling shampoo, I don't want to smell like lavender or whatever all day!" Before he could react, she squeezed some of the goo from the bottle, just as pink as its container, onto her palm and smushed it against his chest, rubbing the fragrant substance into his fur as he groaned in embarrassment. "Actually," she said, helpfully, "it's 'rose petal sensation'." As she giggled and began to lather up his chest, Dave looked up to the concrete ceiling as if asking for celestial guidance, and accepted his lightly-perfumed fate with a sigh.

It didn't take all that long, all things considered, for them to clean up once they'd actually started focusing on the things a shower is normally used for. Dave and Kelly helped each other get nice and lathered up, working the shampoo in deep (much to Dave's chagrin, as the scent would linger all night) before rinsing it away. Kelly needed more time and attention than her brother, not because of Dave's semen, as she'd complained about, but simply because her fur was so much longer and thicker than the comparatively sleek black cat's. Finally, though, the Parrish siblings were clean, and they hurried to turn off the water and duck into a couple of the fur dryers that lined another room off the changeroom. They'd never leave if they started fooling around again while the hot air jets were working on their pelts, so the secret lovers reluctantly took separate booths to dry themselves off. It helped, though, that these particular fur dryers were tiny and cramped, making the unit they had at home feel positively spacious by comparison. Trying to make room to fool around would have been more trouble than it was worth. When they were acceptably warm and dry again, they moved to collect their clothing, relieved that the room no longer felt freezing cold. After pulling his boxers on, Dave sat down on the bench for a moment, just watching his sister get dressed. She looked up when he sighed after she got her underwear in place. "Davey?" she asked, a blankly curious expression on her face. She hadn't made the connection. Blushing, not wanting to admit the somewhat primitive reason for his disappointment, he averted his eyes and improvised. "Oh, well it's just..." he muttered, "now we have to leave and pretend to be, you know... normal." Kelly sat down next to him and leaned over, resting her head on his shoulder and extending her arm around him. "Awww, come on, Davey," she said, soothingly, "It's not that bad, is it? You've still got me, after all. I'm not going anywhere. And just because we can't act like it in front of people..." she nuzzled against his cheek and smiled at him softly. "...It doesn't mean I don't love you twice." He looked back, genuinely cheered up by that even if he hadn't really been dwelling on the point. Nuzzling back, he picked up his socks and continued getting dressed. "I love you too, Kelly," he replied, before they finished the thought in unison. "Both ways."

Soon, the door to the girls' changeroom was unlocked from within, and the door gently, slowly swung open, to reveal a hastily-combed Kelly Parrish peeking out to make sure the coast was clear. The hallway was still deserted, so she nodded to her hidden companion and quickly exited the changeroom with her brother. They strode quickly away from the door as if leaving the scene of a crime, Dave having to resist the urge to hold her hand and they strolled to the end of the hallway and left. As they walked down the hallways of their school, a calculated distance between them, they kept shooting each other quick grins. Sometimes it was hard, emotionally, to mislead their friends and family, but sometimes, having this wonderful secret together was strangely exciting. As the rose petal-scented siblings walked out the side door of the school and began to loop around to the front, Dave leaned in towards his sister, lowering his voice after making sure no one else was nearby. "Say, Kels, I was, uh, going a bit energetically there towards the end," he whispered, "Everything okay?" Kelly blushed as she looked down towards her feet and fiddled with her tail, blatantly displaying her discomfort. "W-well, I'm actually a little bit sore," she muttered, "b-but that's okay, it's not that bad." He thought about looking around again and then giving her a quick kiss on the cheek, but resisted the urge. He couldn't take a risk like that when they were out in the open like this, where someone could glimpse them from a distance and ruin everything. "Good," he said, simply. They could discuss it in more detail, and they almost certainly would, once they had returned to the privacy of one of their bedrooms.

As they continued walking towards the main entrance of the school, Kelly looked over at him; she was still blushing, but her ears had risen up again, and the sly grin on her muzzle told Dave that she was blushing from a much more positive emotion. "...Davey," she finally said, "As it turns out, I could use your help with my anatomy homework tonight." Stifling his grin down to a reasonable smirk, Dave gave his lover a sideways glance. "Oh yeah?" he asked, "What kind?" The Maine coon giggled quietly, then coughed to regain her transparently false composure. "Well," she said, sounding perfectly sincere, "I could really use your help... locating the G-spot. Those, uh, diagrams are really vague... You know, since you keep offering to help." Dave felt himself twitch in his pants, the very idea of spending the afternoon with his fingers buried in his sister turning him on. He laughed softly, focusing his thoughts on more mundane things so he wouldn't get an obvious tent while walking home with his sister. "I would love to help you, Kelly," he said, brightly, "and I'm glad you're, ah, seeking out my help in your education." He glanced as she did, and when their eyes met, they both snickered excitedly, before looking away and calming themselves. As they came around to the front, the main parking lot peeking around a corner, Dave was not surprised to find the front of the school mostly deserted. They'd been in there a long time. "Hmmm..." he thought out loud, "Definitely won't be able to mooch a ride off anyone." Kelly shrugged and subtly rubbed her butt, giggling again. "That's alright," she said, quietly, "I can use the walk home to walk off the ache in my butt." Dave was about to make the obvious joke about being a pain in the ass when something startled him bad enough to make his tail poof out.

"There you are!" came a loud, enthusiastic voice, "Hi, kids!" After exchanging an incredulous glance, both siblings put on carefully relaxed expressions and turned to discover both Alan and Sara Parrish standing by the family minivan in the parking lot. "Mom! Dad!" greeted Dave, "What brings you guys here?" He smiled at them, trying to hide his growing disappointment that he probably wouldn't be able to spend the afternoon lovingly fingering his soulmate after all. Adjusting his glasses, his father, who looked an awful lot like Dave, beamed at his son. "Well, my boy, we think it's time you started thinking more about college," he said, confirming and worsening the other black cat's woes. "Keene University is holding tours every Friday this month," added his mother, a Maine coon like Kelly, though the exact pattern of her fur was of course very different. Alan nodded at his wife and finished the thought. "It just so happens that this is the only time our schedules give us the chance to go, so we thought we'd surprise you." As their father unlocked the van and stepped back inside, Sara chuckled to herself, beaming with pride. Dave hesitated on the sidewalk, looking to his side to see that Kelly looked even more profoundly disappointed than he did. "You can come too, Kelly sweetie," Sara said, beckoning them over, "You'll be going off to college before too long yourself!" As the siblings reluctantly and remorsefully walked over to the van, exchanging a brief glance that was no less meaningful for its silence, Sara giggled again. "I can't wait to see the facilities," she said, "This is going to be so much fun!"
