When you've been fucking your little sister and your dog, it's amazing the sort of depraved acts that you can find yourself participating in. I pondered on this fact for a moment as I watched Jenna feel up our unconscious mother. She had pulled mom's bra to the side, exposing her tits, and was now playing with her rosy nipples and grinning at me.

"See, she's out like a light," my sister assured me. "You know how she gets when she's been drinking. I bet I could even..." Deciding actions were better than words, Jenna leaned over our mom and began to suckle one of her nipples.

It's hard to be an unbiased judge of how hot your mom is, but the erection in my pants told me that she looked pretty good. Even so, I felt hesitant about actually fooling around with her while she was passed out. Jenna, however, obviously had no such qualms; after she had finished sucking on her tits, she moved a bit further up and actually licked our mother's lips. When she met no resistance, she shoved her tongue into the unresponsive woman's mouth.

"Yuck," she said when she had withdrawn from the one-way kiss. "I can still taste the booze on her. Come on Timmy, the whore deserves to be fucked like this."

Jenna's words startled me, and for a moment I wondered if they were genuine or whether she was just trying to get a rise out of me by talking dirty. If it was the latter, however, I was ashamed to admit that it worked; Jenna knew how to press my buttons too well. "Help me get her undressed," I said, and my sister squealed in delight.

Together, we unbuttoned her pants and pulled them off, followed by her panties. Unlike Jenna's bare crotch, mom had a dark patch of well-groomed pubic hair above her pussy. Suddenly it hit me that I had a full grown woman before me, unconscious and totally at my mercy, and my hesitation began to melt away. Getting down on my knees, I spread my mom's legs wide and gave her pussy a big, long lick. It was the second human pussy I'd ever had, and I couldn't help but notice it tasted slightly different than Jenna's.

While I worked my tongue into our mother's vagina, Jenna turned to survey the coffee table. It was covered with beer cans, mostly empty, although a few were still unopened. She grabbed one of the unopened ones and pulled on the tab, then tilted her head back and took a big swig of the stuff. When she had swallowed a few mouthfuls, she stuck out her tongue and made a face.

I looked up from mom's crotch and licked my lips. "I thought you said said 'yuck' earlier."

Jenna shrugged. "It is gross, but I guess I could get used to it." She took another defiant swig of beer, probably more as an act of youthful rebellion than any actual desire to drink. Under different circumstances I might have told her to stop, but since we were also in the middle of molesting our mother, I figured I'd let her do as she pleased.

While Jenna finished off her can of beer, I decided to skip the rest of the foreplay and get right down to it. Unbuckling and dropping my pants, I grabbed my cock and positioned it at the entrance to mom's wet pussy, rubbing the head against her and smearing her labia and clit with pre-cum. Then I took a deep breath and committed the ultimate act of incest, plunging my rock hard cock back into the woman who had given birth to me.

My sister pushed her lithe body up against me, close enough that I could smell the alcohol on her breath, and moaned "Ooooh," in excitement; she had her hand jammed down her pants and was playing with herself furiously. "Do it, Timmy. Mommy wants it hard," she said in a husky whisper.

Since mom was in no position to object, I took Jenna's suggestion. I slammed my cock all the way into her tight tunnel in one go, then pulled all the way back out and slammed it in to the hilt again. Mom lay totally limp underneath me, her tits jiggling wildly as I used her body. Jenna was going wild rubbing up against me, kissing my neck and cheek and nibbling on my ear. Every time I pulled my cock out of our mother's body, I could feel her pressing against me, urging me to thrust it back in.

The situation was intense, and I did my best to hold out for as long as I could, as much for Jenna's benefit as my own. All of a sudden, however, Lucy was there, jumping up and down excitedly and trying to push her head in between us. I shifted to the side to let her in, and was rewarded by the feel of her wet tongue. The nosey dog eagerly licked the spot where I was joined incestuously with my mother, her tongue running along my mom's spread labia, as well as my shaft and balls. Jenna sank to her knees to get a better look, giggling uncontrollably and masturbating.

Lucy's probing tongue proved to be too much, and I knew my orgasm wouldn't be too far away. Instead of slamming my cock all the way into my mom's pussy, however, I changed to short, shallow strokes, allowing Lucy to lick more of my shaft. Then it happened; my vision blurred a bit, and I let out a deep grunt as I began to shoot my load into my mom. Jenna, realizing what was happening, cheered me on from below. "Fill our slutty mom up and let Lucy eat it out. Give her more, Timmy!"

I looked down at our mom, her clothing askew and her breasts bare before my eyes, her face tilted to the side in unconscious repose, and shamelessly pumped spurt after spurt of hot cum deep into her. The entire time, Lucy lapped away, desperately licking up all of the stray juices that were flowing from between our legs. When my orgasm came to an end, I carefully pulled back and allowed the dog to clean me off. When she was done licking my softening cock, Lucy turned to mom and began to lick her, shoving her tongue deep into the woman's used pussy in an attempt to get at the gooey load I'd left inside of her. Jenna squealed in delight and allowed the dog to have her turn before pushing her aside and burying her face in our mother's crotch herself. Not to be denied, Lucy whined and butted against her until my sister finally made some room. I simply sat back and watched the two of them, my dog and my sister, taking turns licking mom's creampie.

That could have been the end of it there, but Jenna and I decided to have a little more fun with the opportunity we'd been given. While Lucy busied herself with mom, my sister striped down naked - save for the dog collar she was wearing - and sat down on the floor while I recovered. Feeling thoroughly swept up by the circumstances now, I happily encouraged the further corruption of the sexy little girl by giving her a few more drinks, and soon Jenna was thoroughly buzzed, approaching full-on drunkenness herself.

"Wannnna fuck me again?" my preteen sister said. She took a swig of beer and spread her legs, giving me an eyeful of her bare pussy. "Hey, I gotta ideeeeeeea," she slurred. "We can do it right on top of mom!"

Without any hesitation, I stood my tipsy sister up and bent her over the arm rest of the couch so that her arms were resting on our mother's bare chest. As I set about placing the tip of my cock between my sister's juicy folds, she giggled and toyed with mom's breasts. Thrusting myself into her, I leaned over Jenna and told her "You shouldn't say such bad things about mom. Why don't you kiss her and show her you love her?" I punctuated the suggestion with a few quick slams.

Jenna turned her face to the side and moaned "I'm ssssorry I called you a slut mommy." Then the youngster kissed her deeply, only this time she didn't pull back immediately, apparently having become more accustomed to the taste of alcohol. Instead she gave the unconscious woman a very passionate, wet tongue kiss; I could hear the slurping and sucking sounds as my obedient little sister did her best to put on a real show for me. I showed my appreciation by stroking her hair and fucking her harder.

Suddenly there was another participant in our little romp. Max pushed Lucy aside and, after a couple of licks at the human pussy laid out before him, decided he wanted more. The dog jumped up and awkwardly attempted to mount our mother missionary. Jenna broke the mother-daughter kiss and looked at him in surprise. Then she burst out laughing. "C'monnnnn Max, you can do it boy!" she teased the dog. Max growled in frustration as he tried and failed to get his red cock into the woman, until at last he succeeded. Jenna cooed and rubbed her cheek against mom's bare flesh while staring up at the frenzied dog; her preteen pussy squeezed down around my shaft wantonly, and I could tell she was really getting off on this. I was too; I wondered how mom would feel if she woke up in the middle of being fucked by the family dog.

We continued on like this for some time, my stamina increased by having already cum so many times today, and Max showing no signs of tiring either. Jenna writhed underneath me, alternately watching Max and licking and nibbling our mother's exposed body. And then Max came to an abrupt stop, apparently having knotted with his passed out mate. "Ooh Timmy, he's cumming in her. Hurry, I want it in me too," she begged. Who was I to deny her? My fingers dug into her tender flesh as I pumped in and out of her, coming closer and closer to orgasm.

Just as I was about to cum, however, mom stirred. She groaned and brought her hand to her face, then mumbled what sounded like "Stop jumping on the bed," in a half-asleep drawl.

I froze immediately, as did Jenna. Max stood tall and satisfied, oblivious to the fact that anything was wrong. After a few short moments that felt like forever, my sister hissed "Hurry up and finish." The smarter decision would have been to grab our clothes and run for it, but mom was lying still again and I felt like I was going to explode. Desperate to cum at any cost, I redoubled my efforts, slamming Jenna much harder than I should have. It only took two strokes before I felt the sudden rush of climax and shot my little sister full of my incestuous seed.

Mom moved again, moving her head from side to side and blindly pushing her hand against Max as though she were trying to figure out what was on top of her. When my balls were totally emptied, I pulled out of Jenna and pulled back. The young girl lay there for a few more seconds, her head resting on one of our mother's breasts. Then she too rose and, giving our mother another quick kiss on the lips, whispered "I love you mommy," then grabbed her discarded clothing and one more can of beer. We both wasted no time high-tailing it out of there and back to our respective rooms, where we quickly shut our doors, leaving Max still knotted with our unwitting mother.

__________________________________________________________________________________________

We never found out whether mom woke up and found Max on top of her, or whether she continued sleeping and simply woke up the next day, half-naked and probably somewhat sore. If it was the former, she didn't show any sign of it. One thing she was not happy to see, however, was Jenna wearing a collar. A long shouting match ensued, until finally she gave in with a disgusted shrug. I had a feeling the issue was far from settled, but for now at least my sister had won.

Months passed and my sister and I settled into our new lifestyle. From that point forward mom drank much less frequently, which was actually somewhat disappointing; we were both eagerly awaiting another chance to molest her together. Jenna, on the other hand, had apparently taken to the idea of alcohol. It was with some guilt that I allowed her to continue the habit, but the results were just too great to pass up - whenever she was drunk, she was also incredibly horny.

Jenna was far from the only object of my affection, however. My sister wasn't available for sex all the time, but Lucy always was. When our mother or friends were around, she was very well behaved, but when I called her into my room and shut the door, she would wag her tail excitedly and make a beeline right for my crotch. And when Jenna and I would fuck, she sometimes seemed almost jealous, whining and butting in between us until we both had to stop and attend to her.

Then one day mom told us that our aunt and uncle were going on a cruise together to celebrate their 20th anniversary, and that their daughter Katherine - our cousin - would be staying with us for a month. When Jenna heard that Katherine would be sharing her bedroom, she was all smiles, but I knew that inside she was quite distressed at the idea of losing all of her privacy for so long. On nights that I didn't sneak in there to fuck her, she had fun with Max.

I was pretty happy about it, though. Katherine and I were the same age, and I had to admit that she was a real beauty. She lived upstate, but the whole family was fairly close and we saw them each year around the holidays. As mom explained the arrangements, I pictured her in my mind - medium length raven black hair, an ample bust for her age that she often failed to hide behind her thick clothing, and curvy hips that displayed a maturity Jenna hadn't yet come into. Realistically, I was certain that nothing would happen, but I knew I would be fantasizing about her nonetheless.

__________________________________________________________________________________________

"I can't believe she's gonna be here for a whole month!" Jenna whined. "And in my room. Whyyyyyyyyyy?"

We were home alone - mom had gone to pick Katherine up at the bus stop. I reclined on my bed and pictured my sexy cousin naked while Jenna paced back and forth. "It won't be that bad," I assured her. "You can always sneak into my room when she's asleep."

Jenna turned towards me suddenly, her skirt whirling and giving me a quick glimpse at her undies. "You wanna fuck her, don't you?" she said with a smirk.

Big surprise there, I thought to myself. Compared to the things we'd been doing, sex with my cousin almost seemed vanilla.

"It's not like it'll ever happen," I said. "I know you're a perv, but Katherine is a good girl."

Jenna stomped her feet. "Awwwww come onnnnn, don't give up, that would be so perfect! Instead of having to sneak around for a month, we'd have a whole new plaything. Come on, let's think of a plan."

While Jenna schemed, Lucy wandered into the room and jumped up onto my bed. The timing couldn't have been more perfect - hearing my sister refer to our cousin as a 'plaything' had my cock rock hard. I got on my knees and, unzipping my pants, pulled out my raging erection. Lucy tilted her head a bit and began to lick me without any further provocation. I pet her head and scratched behind her ears while she serviced me.

"Do you two want some privacy?" Jenna said teasingly.

"You know you're always welcome to watch," I told her. Then I grabbed Lucy's muzzle and gently held her jaws open as I inserted my penis into her mouth. It was a new trick I had been teaching her. The dog sat obediently as I fucked her muzzle slowly. The inside of her mouth was warm and inviting, and she allowed me to push the entire length of my cock into her without complaint.

Jenna was kneeling by the side of the bed. She watched me and Lucy intently, but inside her head she was trying to think up some evil scheme to get Katherine to join in on our incestuous fun.

"We could get her drunk," she suggested. "I'll bet we could talk her into fooling around then."

I frowned and shook my head. "Even if that worked once, what would happen when she sobered up? No way."

My orgasm was approaching far too quickly, so I forced myself to pull out of Lucy's mouth. As badly as I wanted to shoot my load down her throat, Lucy's canine pussy called to me. I tried to roll the dog over onto her back; panting happily, she wrestled with me for a bit before she finally lay still with her hind legs splayed wide. I went to rub her belly, my hands moving lower and lower, playing with each of her little nipples before I found her pussy and stuck a finger inside. Lucy allowed me to pump my finger in and out for a bit, until I withdrew it and brought it to my mouth to suck her juices off. The forbidden taste of animal pussy drove me wild, and I knew the time had come.

"Maybe we could get Max to do something, and then walk in on her," Jenna continued to muse. That idea would never work either, I knew; it was like the lame plot to a bad porno story. "Even if we could somehow make Max do that, Katherine doesn't like dogs," I reminded her. Katherine was a cat person.

Intensely aware of Jenna's eyes watching our every move, I hunched over Lucy's furry body and rubbed the head of my cock against her pink slit. The dog whined and looked up at me, waiting. Then I pushed my shaft into her warm folds as slowly as I could. Bracing myself weight on my elbows, I lowered myself down and thrust myself in to the hilt. It was odd, but strangely hot, fucking a dog missionary. The position had several benefits however - Lucy licked my cheek affectionately, and I was surprised I didn't explode right then and there. Instead, I kissed her on the nose and began to rock my hips back and forth, fucking her gently.

I couldn't quite see from where I was, but Jenna looked flushed and I suspected she was playing with herself. "Awwwww, she loves you so much," my sister cooed.

"Good doggy," I whispered. "I love you too."

Further thoughts of Katherine were erased from my mind as I focused solely on the task of humping my canine lover. The tempo of my thrusts increased until I was slamming into her fast and hard. I was probably being a bit rougher than I should have been; she was an animal, after all, and the last thing I wanted to do was hurt her - or make her hurt me! I was totally lost in the heat of the moment however, well past the point of being able to exercise good judgment, and Lucy didn't show any signs of discomfort, so I just kept going.

My sister was very obviously aroused now. One hand clutched at the bed sheets and her other was out of sight, her arm shaking furiously as she pounded her pussy. "Cum in her Timmy," she said urgently. Her glassy eyes told me that, like me, she was on the cusp of orgasm.

Lucy lay on her back in total submission and allowed me to pump myself in and out of her tight hole. I looked back at her; when our eyes met, she whined and licked at my face again. This time I opened my mouth, and the dog's tongue pushed its way inside. It was an intensely different experience from tongue kissing Jenna, but somehow the carnal act of allowing my dog to lick the insides of my mouth while I fucked her felt right. There was no doubt about it - I was definitely a zoophile.

By this time I had hit my limit - heck, I'd gone way past my limit. Still making out with Lucy, I drove my cock deep into her tight doggy cunt and held it there. Moments later I shuddered and exploded, sending thick cum flooding into her. After the first spurt, I began to thrust into her again, a series of short, swift strokes timed to match each new jet of cum. When I had finally deposited my entire load inside of her, I slumped down on top of her heavily. It was only when my cock had gone completely soft that I slipped out of her and rolled over to lie down beside her on the bed.

I'd completely lost track of Jenna during my powerful climax, but from the way she was resting her head lazily on the mattress, it was plain that she had cum too. She brought up one hand, her fingers glistening wetly, and offered it to Lucy. The dog happily lapped at my sister's sweet juices until her fingers were completely cleaned off.

"You two put on a good show," Jenna said dreamily.

I looked at the clock. "We need to clean up and get dressed, mom will be back soon," I said. Then I gave her a wicked smile and directed her attention to Lucy's cum-oozing pussy. "But first, why don't you help clean her up?" The kinky preteen climbed onto the bed and eagerly buried her face in the dog's gooey pussy. With her butt raised up in the air, I could see that underneath her short skirt Jenna had removed her panties, and I wondered if I'd have time to cum once more.

__________________________________________________________________________________________

Katherine arrived a short time later. We greeted each other with a hug; it was a perfectly normal hello between cousins as far as anyone else could tell, although I was intensely aware of her breasts when they pressed against my chest. Then Max and Lucy bounded into the room, their tails wagging excitedly at the new visitor. Katherine made a face and endured their attention until mom finally ushered them out. Having thus said all of our hellos, we set about helping her unload her luggage from the car.

As it turned out, Katherine had brought another passenger with her - her cat Sourpuss. Despite his silly name, Sourpuss was the friendliest cat I had ever met. And what's more, he seemed immediately enamored with Max and Lucy. For their part, the two gentle dogs were quite confused and more than a little alarmed when this cute little black and white fuzz ball trotted up to them and began to roll around on the ground playfully. Within hours, however, the three of them were acting as if they'd always lived together.

The first week of Katherine's stay passed without incident. She hung out with me and Jenna, we went and did family things with mom, the usual. It was a lot of fun, but the whole time I had to consciously stop myself from openly staring at my cousin's tits and ass. The girl was sexy - she didn't flaunt it, but neither could she hide it.

Jenna, however, was getting quite frustrated. As she had feared, having Katherine sharing her bedroom was a large interference in her sex life. Max and Lucy had to be kept out of the room, and Jenna had to be absolutely sure that Katherine was sound asleep before she quietly slipped out of her bedroom and into mine.

The up side was that all of that pent up frustration led to some fantastic sex. I would pound her hard, and she would whisper all of the naughty things she thought I should do to our sleeping cousin. My sister would cling to me and tell me how she wanted to jack me off until I blew my load all over Katherine's face while she slept, or how we should just hold her down and let Max have his way with her. I knew she was just trying to get me riled up so that I'd be more inclined to drag Katherine into our sex games, thus freeing her to indulge her perversions more freely for the next three weeks, but I had to admit that it was working.

My first real opportunity came at the opening of the second week. Jenna and mom were out, leaving Katherine and me alone for a few hours.

My cousin was a pretty perceptive girl, and she could tell that something was bothering Jenna. We were chatting in the kitchen, Katherine playing with Sourpuss in her lap while I fixed us lunch.

"Jenna's kinda been giving me the cold shoulder," Katherine was saying. "Did I do something to piss her off?"

Obviously I couldn't tell her the truth, I thought. Or could I? After giving it a moment's thought, I decided to throw caution to the wind and test the waters.

With my back turned to her, I spread mayonnaise on a slice of bread and gave a nonchalant shrug. "Oh you know how it is. You two are sharing a room. She's at that age."

I was being intentionally cryptic, and Katherine took the bait. "What age?" she asked, curious.

"I think she just wants some 'alone time' at night, you know what I mean?" It was risky, but I decided to hammer the point home and see how she reacted. "She can't exactly fool around with herself with you sleeping on the floor next to her."

There was a long silence as Katherine digested what I'd said. I wanted badly to turn around so that I could gauge the look on her face, but I forced myself to continue making our meal as if talking about my sister's masturbation habits was the most normal thing in the world.

When the answer came, I breathed a silent sigh of relief. "You think she does that stuff?"

"I know she does that stuff," I said. "Doesn't everyone?"

"Well it's not like she has to hide it from me then. Heck, I bet I could teach her a few things!" She said it jokingly, but of course the image was now burned into my mind indelibly.

Suddenly I realized that the sandwiches were done. Having nothing left to use as a distraction, I put on my best poker face, scooped up the two plates, and delivered them to the kitchen table. Now face to face with my cousin, I continued to probe. Matching her joking tone, I replied "I dunno, I think she knows a lot more than you give her credit for."

Katherine laughed and dug into her sandwich. Between bites, she gave me a coy look and said "You sure sound like you know a lot about what your sister does at night."

If only you knew, I thought. Out loud, however, I said "Jenna and I are pretty close. We've never felt weird talking about that kind of stuff with each other." After a short pause, I bit the bullet. "Heck, we've even masturbated together before."

Katherine very nearly choked. Her face turned beet red and she forced herself to finish swallowing her food. "Excuse me?" she said incredulously.

"We were both curious, so we did some fooling around. Now we're a lot closer because of it, and we've learned a lot of new things about ourselves too." Calling what we did 'some fooling around' was a lie of omission at best, but I didn't want to shock Katherine too badly.

There was a long silence. Still obviously shocked and embarrassed, my cousin studied me as if she was seeing me in a whole new light. Then, probably not knowing how else to react, she resorted back to her earlier humor. "So Jenna has even more experience than me now?" she said, rolling her eyes. "That's just great."

"Maybe I could teach you a few things, then," I said, making my intentions perfectly clear. Leaning across the table, I reached over towards her and seductively lay my hand on top of hers. She looked like a deer caught in headlights, but I couldn't help but notice that she didn't pull away from me. She looked so pretty, so vulnerable, I knew I couldn't turn back now.

Seconds later I was all over her; Katherine barely had time to squeal as I leapt out of my chair and kissed her directly on the lips. She sat there stiff as a board while I pawed at her breasts through her shirt. Her lips parted ever so slightly and I seized the opportunity to push my tongue into her mouth. That triggered a response; my cousin began to kiss me back timidly. Then she arched her back and pushed her chest up against my hands.

Moaning into Katherine's mouth, I reached down and tried to slip my hand underneath her shirt, only to end up with a handful of fur. Sourpuss - I'd completely forgotten that the cat had been napping in her lap, and now he was blocking my access to my sexy cousin's tits. Reluctantly, I broke the kiss and looked down to see the kitty yawning sleepily. Katherine's eyes were closed and she sat there in a daze with her mouth still open a bit, her lips glistening with saliva and her pink tongue sticking out ever so slightly. Then she snapped back to reality; her eyes opened slowly, and she followed my gaze down towards the cat in her lap. We both laughed nervously.

"Time to move, buddy," I said, scooping the cat up and depositing him on the floor.

The interruption had given Katherine just enough time to start having second thoughts. Still gazing down at her lap, she said "Tim... you're my cousin. Jenna... Jenna is your sister. This is bad."

"It's not bad. In fact I'm gonna make you feel really good." I shot her a mischievous grin. "Isn't that what family is for?"

She couldn't help but laugh. "You perv, that's gross," she said, but she was smirking, and to my relief she pushed her chair away from the table and began to undress. Our lunch completely forgotten, I moved to help her, pulling her shirt over her head, then unsnapping her bra strap. She wiggled out of her tight cut-off jeans, leaving her wearing only a pair of black panties. "You're the first boy to see me naked," she mumbled, blushing.

Where Jenna's body was just barely budding into womanhood, Katherine's was blossoming. She wasn't skinny, but neither was she overweight - not by any means. The only word I could think of to describe her curves was voluptuous. Her tits weren't huge for her age, but they were certainly more than I was used to having, and they had a youthful perkiness that my mom's had lacked. "You look amazing," was all I could say, and was rewarded with a bashful smile from my cousin.

Breathless with anticipation, I hooked my fingers around the elastic band of her panties and began to pull them down. Katherine slumped down a bit, shimmying sexily and allowing me to remove her last garment. When it was gone, Katherine spread her legs and allowed me to gaze upon her tender teenage pussy; it was crowned by a neatly groomed horizontal bar of black pubic hair, and her lips moist lips were parted ever so slightly from arousal. It was mouth-watering.

Kneeling between her legs, I looked up at my cousin and said "Just relax and let your cousin show you how much fun this is." She nodded, either warming up to the idea of incest or too horny to care, and I dove in. She flinched and let out a soft moan as I dragged my tongue up her labia and flicked it against her clit. I repeated this a few times, then pushed my tongue in between her wet folds and tried to probe deeper. She twisted and whimpered in response to my every move; I could tell she was going to be a noisy one, and it turned me on even more. When I added a finger into the mix, plunging it into her pink tunnel while my tongue lashed at her clit, the whimpers became full on cries of pleasure. Totally swept up in the moment, Katherine grabbed a fistful of my hair and urgently pressed my face to her crotch.

I ate my cousin out for as long as we both could handle. It was hard to tell just how much time passed with my tongue jammed against her pussy, but it must have easily been twenty minutes. I was loving every minute of it, but eventually my tongue got tired. Katherine groaned in disappointment when I finally pulled away from her dripping pussy. "Noooo," she whined lustily. "Keep going."

Suddenly I had a very naughty idea. She seemed totally past the incest thing by now, so I decided to see if I could drag her further down the path of depravity. "Sit down on the floor," I instructed her, and she did so without a word. Propping herself up on her elbows, she lay back with her chest heaving and her legs spread wide, while I stood and went to the table. There I found a stick of butter, left out from breakfast hours ago and soft from being at room temperature. I collected a decent amount on my fingers, then knelt by my cousin.

"What are you doing?" she said, confused but too horny to protest as I smeared the butter all over her pussy.

My plan worked even better than I had anticipated. Sourpuss came running almost immediately; my cousin's cat loved the taste of butter, and it apparently didn't bother him at all that it was mixed in with Katherine's feminine juices. "No, Sourpuss, bad!" she cried. When she tried to close her legs, however, I forced them back open, and she looked at me in shock. "What the heck are you doing?"

"Relax and go with the flow," I said soothingly. "Just trust me, let Sourpuss have a little bit of fun too."

"Timmmm, not my cat," she protested feebly, but it was too late. There was a sharp intake of breath as the cat's sandpapery tongue contacted with Katherine's sensitive flesh. "Ahhh," she gasped. "Oww, it's rough!"

Sourpuss continued to lap away at his master's pussy, avidly going after the butter while stimulating her at the same time. Katherine wasn't struggling anymore, so I let go of her legs and she kept her legs spread, allowing the cat access to her privates. She was panting and gasping like crazy again, the slight pain of Sourpuss's rough tongue being eclipsed by and melding with the pleasure she was feeling.

Pleased with how easily she had taken to letting her cat eat her out, I started to play with her tits. I squeezed them gently, then traced my fingers around her pink areolas and tweaked her nipples. "Why don't you tell Sourpuss what a good kitty he is?" I suggested.

"Mmmmmmmmmmnnnnn, good kitty," she moaned shamelessly. "Keeping licking, Sourpuss, I need to cum."

It was a good thing we were home alone, because Katherine was getting pretty loud. Lying down beside my cousin, I escalated the nipple play by taking her left breast into my mouth and suckling on it. At the same time, I found her hand and guided it to my crotch. Her strong reactions were really turning me on, and my cock had formed a very obvious tent in my pants. She grasped it through the fabric, then fumbled sightlessly for my zipper.

When she had unzipped my pants, she reached inside, found my throbbing member, and began to stroke me wantonly. I pushed myself closer to her until the head of my cock rubbed against the side of her thigh, smearing pre-cum along her bare flesh, just inches away from where Sourpuss was sitting and licking her clit.

The relentless stimulations all along her body, and possibly the kinkiness of the entire situation, finally pushed Katherine over the edge. Her body went stiff as a board and her chest heaved violently as a powerful orgasm overtook her. Throwing back her head, she managed to utter a strained "Oh fuck," which was followed by a series of deep gasps and primal cries that were beginning to border on shouts. Most of the butter I'd smeared between her legs had been replaced by her own feminine juices, but Sourpuss seemed to like the taste just the same. Completely oblivious to the girl's fit of pleasure, the cat hungrily lapped up her juices. I continued nursing at her tit and grinding up against her as she rode out the waves of pleasure.

When it was over, her body went limp. Totally over stimulated by this point, she lazily reached down and tried to get Sourpuss to stop licking her. It took a little prodding, but eventually the cat got the message and sat down a few feet away to give himself a bath. I unlatched from her nipple and lay there, stroking her hair soothingly.

"That was soooo... weird," was all she could say.

"But you loved it," I teased her.

Now that her head had cleared she didn't want to admit it, but it was obvious that she had. Not half an hour ago she had seemingly been a good girl, pure and innocent; now she was lying naked next to her cousin, having just been gotten off by her cat. It must have seemed absolutely surreal to her. If she could have seen what was going through my head at that moment, however, it would have been even crazier - I was already wondering how I could get her to fuck Max.

But before any of that could happen, I was going to have my turn. After I'd given my cousin sufficient time to recover, I got up and positioned myself between her legs. Katherine looked up at me, then down at my rock hard cock. She looked nervous, and it occurred to me that this was probably her first time.

"Are you a virgin?" I asked her.

She nodded bashfully, then added "But I broke my hymen doing gymnastics years ago." Then she looked up at me. "You have to use a condom."

Ah hell. Despite the fact that I knew it was stupid, I'd never used a condom with Jenna. Consequently, I didn't even HAVE any condoms. I leaned over her and looked directly into her eyes. "Let's just do it like this. Just this once. It'll be fine, okay?" The tip of my cock brushed against the lips of her pussy ever so slightly, a subtle promise of the intimacy - and danger - of having nothing in between us.

Katherine frowned at first, reluctance plain on her face, but then she gave in. "Umm... okay... but only once."

I felt a little bad for taking advantage of her inexperience and naiveté. At the same time, however, I felt a strong surge of satisfaction at her submissiveness. I already had her eating out of the palm of my hand, and I had a feeling it wouldn't be long before Jenna joined me in dragging Katherine further down the path of depravity. The image of my younger sister dominantly pushing her older cousin's head down between her legs suddenly popped into my mind; she was going to have a lot of fun.

Then I snapped back to the present as Katherine shifted underneath me apprehensively. I smiled reassuringly at her, then bent lower and gave her a soft peck. Her body arched upwards, and I felt her breasts press against my chest. Our lips locked, tongues dancing wantonly. Reaching down between our legs, I struggled to guide my cock to her entrance; when I found it, I pushed my way inside.

Katherine moaned into my mouth and almost bit my tongue in response to her first penetration, but otherwise took it well. The walls of her pussy clenched down around my shaft, but it nevertheless slid easily into her inviting depths. When I'd thrust my entire length into her, I stopped and allowed her to get used to the sensation. She'd thrown her arms around my back, and she was squeezing me tightly against her body. We lay there together for a long moment, locked in an incestuous embrace.

I looked down at the beautiful girl lying beneath me and couldn't believe how lucky I was - again. Her long, dark hair had somehow remained nice and neat, save for a few strands that had fallen over one of her eyes in a fashion that I found incredibly alluring. "How does it feel?" I whispered to her.

She responded with a moan. "Mmmm... it's good... you can start moving now."

That was all the encouragement I needed. Her fingers clenched in anticipation as I began to thrust, slowly at first. It was her first time and I wanted to go easy on her. More importantly, I was afraid that if I went all out I'd cum immediately, and I really wanted to savor this first time. Jenna had turned out to be just as twisted as I was, and Katherine had had an innocence she'd lacked. Coercing her into such taboo acts was giving me a certain sense of wicked satisfaction beyond the visceral sensation of sexual pleasure.

As impure and selfish as my intentions were, Katherine was really starting to get into it. She twisted and grunted underneath me, and she had begun to gyrate her pelvis up against me in, encouraging me to fuck her harder and faster. I obliged her, but only slightly, pleasuring her and teasing her at the same time. In desperation, she lifted her feet up from the ground, wrapped her legs around me, and began to try to push me deeper into her.

Satisfied with her display of lust, I stopped holding myself back and gave her exactly what she wanted. Without any warning, I pulled nearly all the way out, then slammed my shaft all the way back into her. Katherine's eyes flew open and she let out a cry of surprise, but I stifled the sound by pressing my lips to hers as I hammered her tight pussy. She picked up this new rhythm quickly, her body rocking in time with mine, her hips bucking forward to meet each of my strokes.

I tore myself away from her mouth again and whispered obscenities to her. "You love getting fucked by your cousin?"

Totally caught up in the heat of the moment, she gasped. "Yes... give it to me Tim! Give it to me just like your sister."

The clever girl had obviously picked up on my incest fetish. It seemed to be working for her as well, in fact, as I felt her soft inner walls squeeze down harder against my pistoning cock. Katherine was clinging to me so hard that it was actually starting to hurt, and she had begun to shake slightly. I guessed that she was cumming again, her second orgasm of the day.

By the time hers subsided, I was about to blow my load. Although still in that post-orgasmic fog, Katherine must have guessed it, because she suddenly looked at me plaintively and said "Please don't cum inside me, Tim."

It would have been the easiest thing to ignore her and do it anyway, and in truth I really wanted to. The potential damage had already been done anyway; pulling out would barely mitigate the risk of pregnancy. Nevertheless, my guilt finally won out - maybe for the first time ever - and I decided to give her this one thing.

My cousin unwrapped her limbs from around me just in time. With a wet slurp, I pulled all the way out of her dripping pussy. I grabbed my cock, slick with her juices, and began to jerk it furiously while pointing it directly at Katherine's curvaceous body. She lay there, spread-eagle and panting heavily, and waited for what she knew was about to come.

With a grunt, I let my first spurt fly. Katherine squeaked and flinched in surprise as the powerful blast flew long and splattered against her, leaving a trail of sticky semen leading from her chin all the way down to the valley between her heaving breasts. The next spurt coated her tummy, then another.

When the last bit of cum had been squeezed out of me, I looked down at the erotic aftermath. The prolonged foreplay of undressing my cousin, making her cat get her off, then taking her virginity myself had left me extremely turned on, and so my load had been a bit larger than usual. Aside from her chin, Katherine's pretty face had been spared - unfortunately - but several dollops had landed on her breasts, including her left nipple. Her tummy was a complete mess, however; there was cum everywhere. I had even left a milky-white pool in her belly button. The streaks of semen led all the way back to her crotch, where some of it had seeped down into the dark strip of pubic hair just above her clit.

Katherine looked stunned, and I remembered that this was the first time she'd seen a guy cum - in person anyway. All she could say was "Whoa."

Scooping up a bit of cum from her abdomen, I lifted it to her lips. "Come on, just a little taste," I said teasingly. She eyed my gooey finger hesitantly, but finally curiosity won out and she took the digit into her mouth. "Hmm... it's not bad," she decided.

Nothing short of a shower was going to get Katherine clean at this point, so we had to postpone lunch even further. As Katherine gathered up her clothes, she said "Don't tell anyone about this, okay?"

There was no sense lying to her, so I told her the truth. "I'm gonna tell Jenna. But don't worry, she can keep a secret." In fact, I guessed that the two of them would have some secrets of their own come tonight.

"So you really... had sex? With your sister?" she asked, apparently okay with my keeping Jenna in the loop.

"Pretty regularly," I admitted. "If you want, I can tell you all about it after your shower."

Katherine rolled her eyes. "All this time you two have been total perverts and I didn't even know it. You weirdos."

I gave her a quick kiss on the lips. "You don't even know the half of it," I said jokingly.

_________________________________________________________________________________________

I didn't quite tell Katherine everything - for instance, how we'd molested out drunken mother. I downplayed a lot of our dog fun too, telling her that Jenna had let the dogs lick her just like she'd let Sourpuss do to her. Katherine still wasn't a big fan of dogs, but I was hoping that we'd be able to change her mind on that subject.

When Jenna got back later that evening, I pulled her aside and told her that 'something' had happened between Katherine and me. She excitedly demanded more details, but I told her it could wait until later tonight. Despite her pleading, I wanted to tease her a little bit. What can I say, I loved to torment her.

After midnight, when everyone had supposedly long since gone to bed, I quietly snuck out of my room and down the hall towards Jenna's room. Without so much as a knock, I turned the doorknob and slipped inside, wondering what I would find waiting for me. What I found didn't exactly surprise me.

Apparently Jenna had decided not to wait for me to give her the full details, but had rather had a little chat with Katherine herself. By the time I got there, they were both naked. My sister was sitting on the side of her bed with her little legs spread and our cousin's head working busily between them. Jenna had a fistful of Katherine's hair, giving the distinct impression that the kinky preteen girl was definitely the one in charge here.

Katherine didn't even look up from licking away at Jenna's hairless slit. My sister, however, turned her bliss-filled gaze towards me and smiled. "Hi Timmy," she said. "We were just having some girl talk. Wanna play?"

I knew one thing for sure. This time, I definitely wasn't going to pull out.
