I Love You Twice: Nocturnal Intermission

By Green

David woke up. Without moving anything except his eyes, he glanced up towards the window on his wall. Pitch black. He glanced "upward", toward the clock on his bedside table. In harshly glowing red numerals, it informed him that it was a few minutes before five in the morning. He could find no reason he would have woken up.

_ Okay. So why the hell am I awake?_

He was about to shrug it off and go back to sleep, when he sensed more than saw movement near his feet. Immediately his pulse jumped and every muscle in his body stiffened. There was someone else in the room with him.

Someone laid a hand on his tail, through the blanket, and a voice softly cut through the darkness.

"So you're finally awake."

His confusion only deepened. He tried to keep his voice low.

"Kelly? What the hell are you doing here?! It's the middle of the night! You scared the crap out of me!"

David reached over and turned on his reading lamp. His room was softly illuminated, and he saw that he wasn't crazy; his younger sister really was sitting on the edge of his bed. A calm smile rested on her lips, and the yellow light of the weak bulb made her fur seem almost luminous.

Kelly was 15, two years younger than David, and while nobody would mistake either of them for anything other than cats, they really didn't look like siblings. She most closely resembled a Maine coon; her fur took after her mother's, and was a mixture of soft whites, browns and blacks, not really forming any consistent pattern, with stripes running the entire length of her tail. She let her deep brown hair grow long, and it currently rested just below her slender shoulders. David, on the other hand, looked much like his father, who was jet black from ears to toes, although David also had a patch of white fur right in the centre of his chest in the shape of a four-pointed star, over his heart. He had been told he probably got that from his grandmother, who had been as white as morning snow. His own hair, he kept trimmed fairly close to the length of the rest of his fur. He was a good deal taller than Kelly, as well, though he wasn't exactly a towering behemoth. All in all, they really didn't look they were even distant cousins, let alone brother and sister.

And now this brother was trying to wrap his head around his sister's inexplicable presence in his room. It is an automatic response, when a person is looking at another person, to take inventory on what they are wearing. So it wasn't really David's fault when his eyes dropped from hers and travelled to her chest. Even if she was just wearing a flimsy white T-shirt and her nipples showed through quite clearly. He was only really half awake, so it came as no surprise when blood began flowing into his penis the instant he recognized what he was looking at.

_ Oh God, no! Not now! Please, not now!_

David forced his eyes away from his sister's breasts, and ever so slowly began to raise his left knee. This pulled the blanket, which was resting tight against his body, off of his groin.

"Davey, I came here because I... I have something to tell you. Something important."

He gave her the kind of look all brothers give their sisters from time to time, momentarily forgetting the fact that he was at half-mast because of her.

"And it couldn't wait past 4:55?"

Kelly smiled that odd smile again and averted her gaze as if embarrassed. She held up one hand. Hanging from it was the Emergency Keychain, which contained spares to the keys for every lock in the house. Their mother had insisted on it. She hadn't even let her children put locks on their doors at all until they were 12, in case there was a fire. Ordinarily, the keychain was kept on a peg right next to the front door, and was not to be used unless it really was an emergency. And now Kelly was casually, calmly, holding the keychain up by the copy to David's room key. If Dave had been more awake, it probably would have occurred to him earlier that Kelly shouldn't have been able to get in at all.

"Actually, I've been here since 4:30. You're a pretty heavy sleeper, Big Brother."

She shifted her legs, and David realized, much to his shock, that she wasn't wearing her usual black, baggy pyjama bottoms. The only thing she was wearing below the waist was a purple pair of panties. The thought immediately jumped into David's head: his sister had been on his bed watching him sleep for the better part of half an hour in her underwear. He was now as hard as steel, and it wasn't going down any time soon. He was finding it difficult trying to continue a conversation with her with his dick straining against his pyjama pants.

"I can't think of a way to be subtle about this, so I'm just going to come out and say it, okay?"

_ I'm gonna guess that's a rhetorical question._

She took a deep breath (which had a delightful effect on her breasts, David noticed with equal parts pain and delight), steeled her eyes, and finished.

"I know you've been - been touching yourself with my panties."

David simultaneously felt his heart skip a beat and his stomach drop like there was no bottom. Every muscle in his body tensed once more, and this time he was more afraid then when he thought a prowler had come into the room.

* * *

Early one morning eight months ago, Dave walked into the bathroom, ready to take a shower. He was already in the process of opening his bathrobe when he opened the door - to be greeted by the sight of his little sister, just stepping out of the shower, clad only in fur and steam. She, in turn, got an eyeful of her big brother, as his robe was hanging wide open. Both of them froze for an instant, then embarrassment took over and he ducked out of the room, muttering apologies. They both took the usual teenage response to embarrassment; they pretended it never happened. Kelly never forgot to lock the door again. But to David's surprise, he couldn't stop thinking about it. He first realized that it wasn't just embarrassment when he was masturbating one night and the image of Kelly, surprised look on her face, reaching for a towel, popped into his head just as he came. His orgasm suddenly became much more intense. After that, he caught himself staring at Kelly several times a week. He stared when she came home from the gym in her sweatpants and sleeveless top. He stared when she came by with friends, in any one of her outfits that were as unique as they were stylish. He stared when she came downstairs in the morning, in shapeless, form-hiding PJs and a serious case of bedhead. He didn't have to be a rocket scientist to realize that he was attracted to his sister. He'd looked around the internet for advice, and was surprised that rather than being confronted with a million cries of "incest is devilry!" he found a vast sea of people who shared an interest in in-family relations, as well as numerous erotic fiction archives dedicated to the subject. He found himself emphasizing with an extremely common thread in the stories he read: he'd never thought of Kelly in anything remotely close to a sexual way before he saw her naked. There had been "girls", and there had been "his sister". Two very, very separate categories that only recently started to blur. He found himself using "normal" porn less and less, and incest porn more and more. He generally didn't bother with mother/son or father/daughter stuff, and not having any feelings for other guys, he just stuck to the category that was closest to home: brother/sister relations. It didn't matter whether the story he was reading was about a pair of leopards, foxes, or even manatees, whenever he finally came, he was thinking about himself making love to Kelly. And his orgasms were more powerful than at any other point in his life.

And then it happened. Three weeks after he saw her, on a Friday, he was going through a big pile of laundry because he'd left his cell phone in the pocket of his shorts. He found the shorts, but sitting on top of them was a pair of pink panties with hearts printed on the elastic waistband. He wasn't sure why he did it, but after hesitating a moment, he grabbed the panties and shoved them into his pocket. He quickly took the cell phone and went straight up to his room. He took the panties out of his pocket and stared at them. He turned them inside out and examined the crotch closely. There was a slight sweat stain, since there had been a heat wave at the time, but that only served to prove to him that they had in fact been worn.

_ This fabric has touched my sister's - has touched Kelly's pussy._

He was already rock hard, and he hadn't even undressed yet. He knew what he was doing was wrong, at least on a moral level, but his arousal was so strong that he couldn't bring himself to stop. Of course, even if he could, he wouldn't have wanted to. With one hand, he wrangled his clasp and zipper open, and pulled down his pants and boxers. With the other, he brought Kelly's panties up to his muzzle, and took a hesitant sniff. Since the scent was pleasing instead of punishing, he pressed them right against his nose and took a deep breath. The smell of his sister's intimate parts was intoxicating; he couldn't ever remember being so hard before. He grabbed for the hand lotion on top of his dresser, and then hastily lubed himself up. He stroked himself hard and fast, keeping the panties tightly pressed to his nose. Kelly's most personal scent filled every part of his being, as if it were a wonderful drug.

_ I'm probably the second person ever to smell this, including Kelly!_

Dave went weak in the knees and dropped to a kneeling position, his hand continuing to stroke back and forth across his aching, throbbing penis. Finally he reached the peak of his pleasure, and it was all he could do not to roar at the top of his lungs as he erupted, spurting his come like it was a distance competition. He'd had entire orgasms in the past that had brought him less pleasure than each individual spurt this time. His mind was completely empty, and he was completely happy. He kept on stroking, and his manhood kept on throbbing, it felt like it would continue until the end of time. After what seemed like an eternity, it was finally over, and he fell back, sitting on the carpet. For a few minutes, he just sat there, his head spinning, trying to sort out the tornado that was happily re-arranging his mind.

The first thing he did, apart from cleaning up the mess he'd made, was throw the panties in his old footlocker. There was no part of him that didn't think it was wrong, but he made no effort to stop himself. That night at dinner, he found himself unable to look his parents in the eye, or even glance in Kelly's general direction. All he could do was think about what he had done. It became so much worse the one time she directly addressed him.

"Hey, Davey, could you pass the salt?"

_ I know what your pussy smells like._

"Here."

_ I know what your pussy smells like._

"Thanks."

_ I know what your pussy smells like._

It was a very good thing that his face was covered in fur, because he was blushing like it was going out of fashion. Fortunately for Dave, his father Alan's boss, who wasn't exactly his best friend, had made a terrible business decision, and Alan was quite happy to rant about it without his son's participation.

He found, over the next day, that his mind kept drifting back to the panties in his locker. It got to the point where he realized he'd read the same e-mail about 20 times, and he still had no idea what it said.

_ Oh, to hell with it._

He opened up the locker and removed the panties with as much reverence as an archaeologist discovering a long-forgotten relic. He immediately brought them back up to his nose, and was disappointed to discover that the smell of his sister's musk had diminished significantly. The scent that lingered, however, was still strong enough to set every cell in his body to tingling. Inspiration struck him and he removed his clothes again. After one last deep sniff, he took the panties away from his muzzle and tenderly wrapped them around his growing penis. He began to vigorously rub his genitals with the panties that had touched his sister's. The delicious friction this caused sent electric waves of pleasure from the tip of his erection all the way up his spine. He kept rubbing the panties over his swollen flesh like his life depended on it.

_ I may not be able to smell her anymore, but this is like, one step removed from fucking her!_

That thought filled his mind with the most vivid image yet of himself making love to Kelly. He could almost hear the noises they were making, practically taste the sweat that was soaking into her amazingly soft fur. It was that image, more than the actual stimulation, which made him unable to last as long as he normally did. He groaned out loud, and quietly gasped his sister's name as he ejaculated, soaking the cotton underwear with his seed. It took a lot out of him. He allowed himself to fall backwards, lying naked on the floor of his room, and panting like he'd just ran a marathon. He lay there, quite peacefully, for several minutes. Meanwhile his penis, still wrapped in the come-saturated panties, slowly shrank back to its normal size. The stimulation he received as his member dragged itself out of the underwear was enough to cause some minor "aftershocks", his flaccid member throbbing slightly, releasing some leftover semen. Finally he opened his eyes and sat up. He felt like a different person than the hormonally-driven beast he was a few minutes ago, filled with guilt as he stared down at himself, realizing what he'd done. He gingerly picked up the panties - his little sister's underwear! - now drenched in his juices. What the hell was he going to do? His parents weren't stupid. If they found this in the laundry, it would be obvious that it was soaked in come, and it certainly wasn't his father's. On the other hand, if he hid it in his footlocker, sooner or later, Kelly was going to notice that a pair of her panties was missing. He came up with a plan as he got dressed, the panties sitting on his desk like a smoking gun. He threw them into the footlocker, and went to bed.

Over the next few days, David lived his life as normal, to the best of his abilities. Out of embarrassment, he avoided contact with his sister, but it wasn't like they hung out every day anyway. He started walking past the laundry room on a regular basis, making casual conversation with his parents when one of them was in there cleaning clothes, until finally, he came across his mother loading her and Kelly's underthings into the washer. She was never the sort to trust her husband with "delicates" so she always did that wash herself. Dave went upstairs and watched the door, and what seemed like days later, his mom finally walked out of the laundry room, the machine loudly filling itself with water behind her. He dashed into his room and opened the footlocker. There were the panties, much as he had left them, though now the semen was dried on. He tucked the underwear behind the waistband of his pants and hurried downstairs. Now shaking with anxiety at the thought of getting caught so close to freedom, he closed the door of the laundry room behind him and added the sperm-saturated panties to the wash.

Sure enough, the washer and drier did their job and obliterated all trace of what he had done. Kelly didn't notice that one of her pairs of panties had been missing for a week, but then, underwear is not very high on most peoples' priority list. And so, Dave's life returned to what it was. Sort of. A couple of weeks later, Dave realized that he had become unhappy with regular masturbation. The orgasms he got from just using his hands were much weaker than either of the ones he'd gotten from Kelly's panties, one using his sister's smell as incentive, the other using her underwear as stimulation. And the thought popped quietly into his head, quite uninvited.

_ You didn't get caught the first time, why not try it again?_

At first he banished the idea from his mind, actually ashamed he was even thinking this. But as the days passed, the concept came back again and again, and what started out quiet got louder and louder in the back of his head. Finally, one day when he was particularly horny, he gave in and stole another pair of his sister's panties from the laundry.

And so it began. Every couple of weeks he would steal a pair of Kelly's panties from the laundry, and carry out the same ritual. He'd masturbate while smelling them, and later masturbate with them. He'd seen clothing fixations all over the Internet, but to him, this wasn't about the panties, it was about who had worn them. Still, there was at least a small part of him that saw that masturbating with your sister's underwear is not something most people do. Dave began rationalizing his actions to escape from the guilt, and at that, he succeeded.

"It's not like it's hurting anyone. I could be sneaking into her room at night and touching her in her sleep or something." He'd say to himself.

"I always return them, and no one else even has to know."

He took extreme care never to get caught. He wouldn't even go for the panties if all three people he lived with were home. He was always very careful to return them to the washing machine so that any trace of what he did was removed. At first he would only put the underwear directly into the wash himself, but later, as he got more and more comfortable with what he was doing, he realized that his family didn't pay particularly close attention to the clothes going into the wash. Once, he waited until his stuff had dried, and put the panties in the laundry with the rest of the dirty clothes. Although he was unbelievably nervous that day, no one said a single word about it. Emboldened, he put the next panties he swiped into the laundry bag as soon as he was done with them, still glistening with his semen. The delicates wash was days away, and his seed had long since dried by the time it came time to be handled by someone else. He gradually became comfortable with his secret ritual. Comfort eventually gave way to confidence. He believed he'd found a system that worked, and as long as he was careful, it would stay his secret. The thing about confidence, of course, is that it leads somewhat inevitably to making mistakes.

* * *

And now, Kelly had silently entered his room, waited until he awoke, and told him she knew what he'd been doing. It was the most horrible thought in the world. She knew. Her big brother, the one she'd idolized as a child, the one she still looked up to as a positive example, had used her underwear for sexual release. She knew. A part of David realized that whenever he'd imagined getting caught, it played out in his mind as his father walking in on him doing the deed, or his mother catching him in the laundry room snatching a pair of panties. He'd never considered the idea that Kelly would be the one to discover him. Somehow, though they were still horrible fates, his father's rage and his mother's disappointment were unimaginably better in his mind than the simple idea that _his sister knew. _ Dave was petrified with fear in a way he hadn't felt since he was six and had snuck downstairs in the middle of the night to watch the slasher movie his parents didn't want him to see. With good reason, as it turned out. But this feeling wasn't a child's irrational fear of a fictional axe murderer who posed them no real threat. It was an adult's fear of the very real possibility of losing his family's respect and love, getting kicked out of the house, possibly even being disowned. They probably wouldn't press charges. Probably.

_ Where the hell did I screw up?! I was so careful!_

He stared in horror at his little sister, leaning back and resting on his forearms, unconsciously trying to put some distance between the two of them, his erection forgotten like the details of his birth. His mind was replaying every detail of the last time he'd done it, just that afternoon. Or at least trying to. He was a bit distracted by the part of his mind that insisted on creating scenarios of what could now happen, each one worse than the last. He felt he should defend himself, should deny it, should say something, but with his thoughts going a hundred miles an hour, he couldn't come up with anything coherent. Nonetheless his mouth insisted on trying.

"Kelly, I-I... I..."

Dave trailed off. He swallowed, hard, and forced himself to speak, tears in his eyes.

"I'm so, so sorry, sis. I don't know what came over me! I-I promise I'll never, never do it again, but please, please don't tell Mom and Dad, they'll kill me, they'll kick me to the curb, oh God, I'm so sorry!"

Dave didn't know whether to cry, throw up, or pass out. He was very close to having a full-blown panic attack. So he can be forgiven, with all this chaos going on inside, for not paying attention to things going on outside. Kelly had just uttered words that, regardless of outcome, would change both their lives forever. She knew a dark secret about him, one that would result in disgust and loathing in most households. And yet she did not look angry with him. Did not look disgusted with his behaviour. In fact, she was sitting quite calmly at the end of the bed, watching him yammer apologies at her, and she was smiling. She was legitimately amused by his reaction.

Without responding to his comments, and without being prompted, Kelly, who was blushing under her fur, began to tell a story of her own.

"After we saw each other in the bathroom, my mind started wandering. I hadn't seen you naked since we were little kids, and I never really thought about you as a sexual person. But then, I didn't know you had such a nice body... or such a nice cock."

David felt encouraged by the fact that she was still talking to him and dared to hope that he might somehow survive this with his parent's love intact. Despite the fear he felt, he still noted that it was a major turn-on to hear his sister talk about him that way. He didn't think he'd ever heard her say the word 'cock' before, much less talk about his. She continued.

"One day, I was surfing the net, and I, uh... I was masturbating..."

Obviously embarrassed, she had to force the word out.

"...but I couldn't find anything that, you know, did it for me. Then I found this one specific video that I really liked. The girl was just some big-boobed golden retriever who was obviously faking it. But the guy was this... tall, handsome panther."

She had suddenly become very interested in her hands, which sat, fidgeting, in her lap.

"Davey, after I ca-"

She closed her eyes, unable to finish that sentence. Dave began to realize that coming here, talking to him like this, was a real effort on her part. Did she hate him so much? If so, what was with the weird smile? And why in God's name was she talking to him about Internet porn?! Now that he thought about it, he was pretty sure she was blushing, but the light was too dim to really tell.

"...after I... finished... I realized something. When I was, uh, going at it, I wasn't thinking about the girl. I usually imagine what it must be like for the girl, you know, being with the guy, but... uh... what I mean to say is..."

Apparently realizing she had just been discussing her fantasy life with her older brother, her eyes snapped open, and now it was her turn to look panicked. She glanced over at the door, obviously considering just bolting.

"Calm down, Kels. Deep breaths. Take it slow."

Dave marvelled at the fact that, even after the bombshell that had started this conversation, he still found himself automatically comforting her.

_ I guess I'm still her brother._

She smiled, but returned her gaze to her wringing hands.

"I just wanted to say that this time, I was thinking about me. About being with the panther, thinking about what his body would feel like on mine, his fur under my hands, his breath on my neck, his thing inside me..."

Dave inwardly burst into tears. Listening to Kelly talking like that was one of the hottest things he'd ever experienced.

_ Okay, it's official. I am_ never losing this hard-on.

"...and then I realized, I wasn't thinking about the panther, Davey. It was just the black fur that was the same. I was thinking... about you."

For a fraction of a second, every part of David just... stopped. Every muscle ceased what it was doing, every thought evaporated like a puddle in the desert, even his heart skipped a beat. He felt like he'd been punched in the stomach. And yet, Kelly was looking at him, waiting oh-so-anxiously for his response.

"You were thinking about me? About... us?"

She nodded.

"I never really noticed before we saw each other, Dave, but... heh... you're really good looking. Every day after that I would... think about you and wish you felt the same way about me that I felt about you, but there was no way I was going to ask! I had just about accepted the fact that there was something wrong with me... and then, earlier today, when I was walking out of my room, I saw you come out of the laundry room."

Kelly's room was on the upstairs landing, directly overlooking the hallway around the laundry room.

_ That_ was my mistake. I forgot to look up last time!

"You looked nervous, so I figured you weren't sorting clothes. I know it was snooping, but I was curious, and I am a cat, after all."

Despite the astonishingly out-of-the-ordinary situation, the siblings shared a smile at one of the cheesiest, oldest jokes shared by morphic felines.

"I found a pair of my panties on top of the pile, but I knew I hadn't worn them since last week, since I'd changed into them after my workout at the gym that Saturday. They should have been washed already, not at the top of a new pile."

David frowned, confused.

"How can you remember the last time you wore that specific pair?"

Kelly smirked.

"When I was getting dressed, the girl next to me was wearing the same ones, and we talked about fashion for a few minutes. Anyway, I might not be the most worldly girl in town, but, uh, it was kind of obvious what you had done."

_ Mistake number two: not waiting until they were dry._

"Dave, I know this sounds weird, but I found a pair of my underwear covered in my brother's stuff, and instead of being gross and nasty, it was one of the best moments of my life! It meant you feel for me like I feel for you. And don't try to deny it, you've had a boner since you woke up."

David was caught, yet he absolutely didn't care. His world had become a very different place since he went to bed.

"I... I don't know what to say, Kels."

His sister smiled, and sat up a bit straighter. Without warning, she pulled her legs up on the bed and began moving towards him on all fours. Dave wasn't particularly worldly himself, but an idiot could read the look in her eyes.

_ Holy mother of God._

He felt a sudden urge to back away from her, one last piece of his mind telling him this was wrong, wrong, wrong. He told that part of himself to go to hell. Her tail was silently swaying back and forth like a pendulum (drawing his attention to the fact that he had never seen this pair of panties, purple with a butterfly pattern, before) as she finally reached the other end of the bed and lay down next to him, her brown eyes inches from his green ones.

"You don't need to say anything at all, Davey."

And with that, she snaked her arms around him, pulled herself in close, and, with only a little hesitation, kissed her brother.

Kelly's mouth was warm and inviting, and Dave was absolutely thrilled to be exploring every inch of it with his tongue. At first, having no experience, he was absolutely paranoid about letting her down.

_ Do I have bad breath? I didn't use mouthwash before I went to bed. Wait, can you taste bad breath? Maybe she wouldn't even notice. Am I pressing too hard with my tongue? Or am I not pressing hard enough... maybe I'm moving around too much._

And so on. Eventually, though, all the fears and worries he had about the act slowly melted away until all there was in the universe was the act itself, pure warm bliss. Time seemed to stop, as Dave kissed his sister for what seemed like forever. After a while, it occurred to David, somewhere in the back of his mind, that his hands were just sitting there, giving Kelly a loose hug. Filled with joy and anticipation, Dave ever-so-slowly lowered his hands and brought them up under her shirt, where he began running them back and forth across her back.

_ My lord, is her fur ever soft._

Soon he could feel her hands exploring his back. His fur was a lot shorter, coarser than her own, but she seemed to enjoy his feel as much as he was enjoying hers. Changing the angle of his head, which changed the feel of the kiss ever so slightly, Dave made a daring move and brought his hands around from her back to her stomach. He wouldn't have thought it possible, but somehow, her fur was even softer there.

Now, Dave had his eyes shut. Not his idea, he would have loved to get a visual on what he was doing, but the impression he'd gotten from the Internet was that only freaks and weirdos left their eyes open during a deep kiss. He had no idea if that was true or not, but he didn't want to take any chances with being a weirdo.

_ Granted, I'm kissing my sister, but the concept is still sound._

So his eyes were tightly shut, which meant he missed seeing Kelly's eyes snap open when he touched her stomach. Not with anger or fear, but with shock and surprise. Had he been more experienced, he would have noticed she also momentarily stopped moving her tongue and hands. He did notice that her face suddenly felt warmer. After a second, she closed her eyes, and focused on the experience again.

He hadn't noticed until he was actually running his hands over her belly, but Kelly was softly purring. He mentally gave himself a high-five. He was not purring himself, but apparently she was more at ease than him, having had all day and not, say, half an hour, to get used to this idea. He ran his hands across her fur, spreading his fingers wide and letting them get slightly tangled. He took a deep breath and ran his hands upwards, under her shirt, towards her breasts. Kelly's eyes fluttered open again, but closed almost immediately. David noticed that her purring was now audible. Having no idea what he was doing, he started by cupping one in each hand and giving a gentle squeeze. She moaned softly, directly into his mouth. It was an interesting sensation. Playing things by ear, he lightly ran his fingers over her nipples, marvelling as he felt them get harder. If his mouth hadn't been otherwise occupied, Dave would have swallowed hard, as he built up confidence within himself for a difficult task. He let his right hand begin to drift lower down her body as his left remained behind to play on her chest. Inch by inch, he moved across her gorgeous curves, until he passed her navel, and s-l-o-w-l-y pushed his fingers under the elastic band of her panties. Suddenly, Kelly broke off the kiss and pulled away from him, sitting up on the bed.

_ No. This can not be happening. This is_ not okay.

"No, Davey, I-I can't. Not yet."

She hadn't run away, or slapped him, just made him stop exploring her. She looked back at him, and this time seemed embarrassed, but not in the same way she was earlier.

"We don't have protection. I don't want to take any chances at all."

Dave was beginning to see where her embarrassment was coming from. Siblings having sex without a condom was an example of amazingly bad planning.

"This was your idea, why didn't you go out and buy some stuff before you came here?"

She gave him a sheepish grin and shrugged.

"I didn't think that far ahead."

A few seconds of awkward silence followed, in which Dave truly understood for the first time why men hate "cockteasers" more than any other type of women. A girl who'd do this to a guy on purpose must be pure evil.

"...I don't suppose we could risk it just this once?"

He immediately regretted saying that, as the withering look he received almost made him forget how horny he was. Almost. Kelly smiled again, a sarcastic grin she often wore when talking to her brother.

"Why, Davey, I had no idea you wanted to be an Uncle-daddy! I guess if fathering a child with your own sister means that much to you we could -"

"Okay, okay, I get it, hands-off. So I guess you're going back to your room now?"

Kelly's smile widened, and her eyes narrowed, her pupils huge and black.

"I said we couldn't have sex. I didn't say anything about 'hands off', now did I?"

Suddenly, she lunged forward, reminding him of a feral pouncing on a mouse, and before he knew what was happening, she was copping a feel of his package through his pyjama pants. She acted as if nothing was out of the ordinary.

"No, I think a hands-on policy will be a wonderful finish to the night, don't you?"

_ Where in God's name did she pick this stuff up? This is my little sister?_

A thought struck him, and he had to force himself not to laugh. Kelly, who'd lived with him her whole life, picked up on this. She looked somehow even more embarrassed than before.

"Too cheesy?"

He ran a hand through her long, dark hair.

"No it's not that, it's just... We just made out, and now you're admiring the goods. I've had dreams like this."

Naturally, once the words were spoken, he was gripped by the terrible, if irrational, fear that this was a dream, and that he would soon awaken, alone in his bed. It soon passed, as Kelly, now with a huge, confident grin on her face, opened the buttons on his fly.

Kelly pulled Dave's pants down to his knees before she stopped, about the same time Dave realized he was holding his breath. He wasn't sure how to react, since Kelly hadn't done much in the way of reacting herself. He hadn't really expected one of the silly comments women made in porno when men whipped it out. 'My God, it's so huge!' But Kelly hadn't said anything at all, she was just... staring at him, moving her head ever so slightly to different angles, like he was a piece of artwork she didn't quite understand.

"You know, if you take a picture, it'll last longer."

She gave him the kind of blistering gaze that only women can produce.

"Har dee har har. That joke's collecting its retirement fund."

She gave a little shrug.

"It's just that I've never had the chance to see one in the flesh before."

Dave's eyes widened slightly.

"Then I'm honoured to be the first."

Finally, Kelly reached out and wrapped her hand around her big brother's penis. For a few moments, she was content merely to hold it, before slowly dragging her hand up and down her brother's aching flesh. The room became silent, all thoughts of banter forgotten by both siblings as Kelly began to stroke faster and faster. Suddenly, David gasped - in pain.

"Ah! ...Don't squeeze so hard, Kels! You're pulling the skin."

Kelly's ears flattened back towards her head, chastised. She stopped stroking, loosened her grip, and then glanced up at Dave, who nodded, trying to look encouraging. Soon she was masturbating her brother with confidence, teasing the loose skin at the base of his shaft and running her fingertips over his straining head. Dave leaned back, settled into his pillows, and let himself fall into the experience. Physically, it was identical to when he did it himself. Not as good, actually, due to Kelly's lack of experience. But it was the mental aspect that made it so much better, just the thought that someone else was doing it instead of him. As Kelly fell into a rhythm, Dave began to smile widely.

_ Could I ever get used to this! _

Suddenly she stopped. Before he could protest this, he was softly hit in the face with... something made of fabric. He opened his eyes and sat up.

"The hell was..."

Dave trailed off, for a very good reason. He realized, without having to look, that the object he had taken off his face was his sister's T-shirt. Kelly now sat back on her knees, naked from the waist up, awaiting her brother's approval.

"I just thought since I've already seen you..."

Eight months ago, David had caught a short glimpse of Kelly's body, and it had fuelled his fantasies in a way nothing else ever had. Now she was freely showing it off to him, and he just sat there and stared, taking in her beauty. The fur on the front of Kelly's body was a much, much lighter shade of brown than elsewhere. He could practically see how it was softer. And it was shorter as well, perfectly framing her breasts, which were making it very difficult to look at anything else. They weren't particularly large, but Dave had never been a fan of huge boobs to begin with. They were the perfect size, in his opinion. A fluffy white tuft was nestled nicely between them, something Dave had always found incredibly attractive in feline girls.

"...Um, wow. Wow. Really, sis, I knew you were hot, but... you're gorgeous!"

She looked a little embarrassed, and a lot flattered.

"Do you really mean that, Davey?"

"I'm pretty sure I'm the luckiest guy in the world tonight."

Kelly began to purr again, and returned her attention to what she was doing. David sat back as his sister's hands ran over his throbbing manhood, and it wasn't too long before the inevitable build-up of pleasure began. He figured Kelly wouldn't appreciate him leaving it a surprise. He just had to get past the embarrassment of actually telling her.

"Uh, Kels? I'm almost, uh, that is, I'm going to, to come soon."

Kelly slowed down, then smirked, tightened her grip, and began pumping her brother's erection in her fist even faster than before.

"Go ahead, Davey. I'm doing this for you, after all."

She had literally given him permission, but following his male pride, he still tried to resist. Tightening his muscles, thinking about golf, his usual strategies for delaying weren't working, because he wasn't the one in control.

"Are you sure, Kelly? It's just that I, I, I..."

The last "I" stretched off into thin air as Dave finally boiled over. He let out a hard, low groan as his back went rigid, his hips thrust forward of their own volition, and his penis began spasming, sending hot jets of semen spurting out into the cool night air. Kelly stopped at first, seemingly mesmerized by her brother's orgasm, and then began pumping again, hard and fast. Dave's vision clouded over until all there was in the world was his tool and his sister's oh-so-soft hand.

After what felt like about four million years, all the "aftershocks" were over, and Dave came back to the world of the living. He became aware of the stucco ceiling of his room, and then sat up. Kelly lay on her side at the foot of the bed, one hand supporting her head, the other dangling before her, playing with the sticky substance on her fingers. A huge, self-satisfied smile had spread across her face. She tilted her head to the side and winked at him.

"Gee, big brother. Was all that for li'l old me?"

She glanced pointedly at his chest, which was now fairly coated in his come. Even Dave himself was impressed; it was much more copious than what he normally produced.

_ Jeez, I hope I still have some left!_

Involuntarily, a smile of his own appeared on his muzzle.

"Damn, Kels. If I knew you could make me come like that, I wouldn't have walked out of the bathroom! Hey, do me a favour and pass me that towel, would you? I really don't want this stuff drying on me."

Kelly reached behind her and grabbed the towel draped across the side of Dave's dresser, taking a moment to wipe off the come that had dribbled onto her hand. As she tossed it to him, her smile grew slightly wider.

"You know, Davey, I could have sworn I already did you a favour tonight. I just can't seem to recall what it was."

Dave cleaned himself up and put his pants back on. He looked over at his sister, feeling on top of the world.

"Thanks, Kels. You have no idea how happy I am that you feel the same way I do. Could... could you come here? I just wanna hold you, if that's okay."

Her eyes seemed to shine as she responded.

"Of course, Davey. Nice to know that you like to cuddle."

Kelly crawled across the bed as Dave sat up and leaned his back against the wall behind his bed. She turned around and pushed back into his chest, her butt firmly pressed into his groin. He wrapped his arms around her in a warm bear hug. The siblings merely sat together, enjoying each other's company, each other's presence, in silence only broken by their mutual breathing. David ran the past hour back through his mind, still shocked at how quickly his life had changed. He leaned forward and inhaled the scent of his sister's hair.

_ Smells almost as good as the fun parts of her._

With that thought in mind, Dave glanced down at the girl in his arms. She hadn't put her shirt back on, but she was still wearing her panties. Without saying a word, he moved his hand down from her shoulders, where his arms were wrapped around her, down her body, towards those panties. When she felt her brother's hand reach between her legs, Kelly pushed it away and began to wriggle in his arms, whimpering in frustration.

"Oh God, Davey, don't do this to me! I want it so bad - want you so bad - but we can't, not without protection!"

He used his other hand to stroke her hair, gently scratching the skin behind her ears. There were some things ferals and morphics shared in common. The sensitivity of that particular spot was one of them.

"It's okay, Kels. I'm just... doing you a favour."

She let go of his arm, and let him reach down her body, but her breathing quickened. He realized that she was just as anxious as he'd been when she first saw his cock. Nevertheless, she kept her face carefully casual, like she hadn't a care in the world.

"Well, I d-do appreciate a man who returns his favours."

Dave pressed his palm flat against Kelly's stomach, which allowed him to feel that her purring was still going strong. Then he slowly slid his hand downwards, until he reached the elastic waistband of the butterfly panties. Her breathing was way faster than it had been moments before, so he continued stroking her hair to calm her down as his hand slid down to cup her groin through her underwear. He began by feeling around at random, getting himself 'acquainted with the terrain', so to speak. Soon he was tracing the line of her slit through the thin purple fabric, up and down, over and over again. He then travelled just northward and felt for the bump of his sister's clitoris, toying with it once he found it. Kelly's hips jumped a little bit, and she let out a quiet moan. As he continued to play with his sister's body, Dave noticed the cotton becoming damp. He lowered the hand that was stroking her hair just for a moment and squeezed her left nipple. Kelly gasped and her entire body jumped. He took a deep breath; he loved Kelly's smell - not just the secret smell from her panties, though that was nice too - the regular everyday scent that emanated from every inch of her fur, the kind that probably wouldn't even be noticeable to a human. More than that though, he loved feeling her body against his, feeling her warmth close to him. In order to touch as much of her body as possible, he snaked his tail out from under his leg to gently rub against Kelly's own tail, which was twitching back and forth like it had been plugged into a wall socket. There was absolutely no mistaking it: Kelly's panties were getting soaked. He could feel her juices soaking into the short black fur on his fingers.

_ Guess it's now or never._

He brought his hand upward once again, flat against her stomach. For the second time, he pushed downwards. This time, though, when he reached her panties, he pushed under the elastic waistband, and found himself in the Promised Land. After silently thanking the twists of fate that had led him to this experience, he ran a finger along his sister's lust-slicked lips, and was surprised by how very hot her nether region was. He gently rubbed at her clitoris again and dipped a finger between her lips, and Kelly bit down on her tongue to keep from crying out her pleasure.

"Jesus, Davey, how often do you do this?"

He felt oddly proud of that response.

"Swear to God, I'm winging it."

She tilted her head back and looked him in the eyes.

"You could give lessons, big brother."

He moved his head to meet hers, and for the second time that night, the siblings shared a kiss, this one even more passionate than the first. As Dave began sliding his fingers in and out of her pussy, Kelly's tongue became much more active, she seemed so much hungrier than she had before. Now, as then, the entire universe faded away around them. All that existed to Dave was the wonderful person lying on top of him, the supple body leaning against him. Nothing mattered except her mouth, warm and inviting; her pussy, doubly so; and her amazingly soft breasts, where he had relocated his free hand, no longer needing to stroke her hair to bring down her anxiety. He continued to push his first and second fingers down into Kelly's vagina, as deep into the warm cavity as he could reach, tracing the shallow bumps and ridges along her inner walls with awe. With every plunge, she let out the tiniest of moans, making for a wonderfully vibrational feeling as she kissed her brother. They had reached the point where a 747 could have crashed in the backyard and they wouldn't have noticed. Pure bliss floating through their minds, the two cats finally gave into the feelings that had been boiling beneath the surface for months and months as they touched each other's bodies, tasted each other's mouths, and felt their lover's heart beating through their skin. Dave increased the speed of his fingers, and Kelly's breathing grew shallower, more erratic. She broke off the kiss and whispered directly into her brother's ear, her voice thick with need and raspy from force.

"Oh, Jesus, Davey... Oh God, I'm almost there. Ohhhh, Davey, I'm so close!"

David kept up his relentless assault on his sister's nether-regions, encouraged by her reactions. He broke his rhythm by suddenly flicking her clitoris with his thumb, and with that, Kelly let loose a long, low moan, arched her back, and tensed up every muscle in her body. Dave continued what he was doing at a slower pace, continuing the pleasure she was feeling, until finally her muscles gave out and she collapsed onto her brother, the both of them purring like a pair of finely-tuned engines.

Kelly turned over onto her stomach and snuggled into her brother, using his chest as a big black furry pillow. For a time they just stayed there like that, basking in each other's company. A few wonderful minutes later, Dave felt he had to speak up.

"Mom and Dad will be getting up soon. We really don't want to be here like this when they do."

Kelly frowned and stayed exactly where she was, hugging him a bit tighter.

"For months I've been wondering what the hell was wrong with me to feel the way I do about you. It's kept me up a few nights. Now I finally find out that you feel the same way, and you want me to leave already? I don't know about you, but I'm fine right here, thank you very much."

Dave reached down and gently tilted her head up towards his.

"Come on, Kels. We've got plenty of time to be together. We both live here, after all. We've gotta be careful and play it low-key. Or do you want to explain to Mom why her two darling children are nailing each other? How about this: I promise we'll pick up where we're leaving it as soon as we can."

He couldn't resist grinning impishly.

And next time we'll buy condoms first."

His sister finally let go of him and sat up.

"Alright, alright. Never thought I'd hear big brother Dave become the voice of reason."

She stood up, grabbed her t-shirt off the floor, and tugged it on as she walked towards the door, before stopping. She turned around, a Cheshire smile spreading across her face. She lifted up the hem of her shirt, exposing the butterfly panties.

"These are completely soaked, Davey. You're really good at stuff when you put your mind to it, you know?"

She glanced into the hallway, checking for signs of movement. Then she pulled her panties down her slim legs and off, standing proudly before him. Dave strained for a glimpse of that which he had felt but never seen, but her fur did too good a job of hiding her treasures away. Kelly held the panties up on the tip of one finger before tossing them to her brother.

"So you don't forget your promise."

Without another word, she turned and walked down the hallway, naked from the waist down, tail swaying in time with her hips. When David could think straight again, he slowly walked over to the door and closed it. It was still a few hours before his usual wake-up time, so he might be able to get some sleep. He lay back on the bed, holding his sister's panties in disbelief, and decided that probably wasn't going to happen. There was just too much to sort through in his mind. So much had changed in such a short time, and he wasn't sure how to feel about some of it. One thing was certain:

His life was about to become a whole lot more interesting.
