She is 23, about 5'4", with auburn wavy hair and bright green eyes. Her skin is a little pale, and she has a hint of freckles on her face and shoulders. Kim has a thin build, with perky B cups and a tight apple ass. The first time I saw her walk away from me in tight little panties, slightly sucked up between her hard cheeks, I was hooked. I am three years older, 6' even, muscular but not huge. Kim likes when I have a beard, so I keep a trimmed one that matches my short brown hair. Kim's little sister Katie has fallen on hard times. Frankly, she's a bitch. I don't often use that term, but she really is. Drugs, skipping school, sexting, all before she even came close to graduating high school. She got kicked out when she tried to seduce a teacher for an A. Once Katie hit 18, her parents kicked her out, and now she is living on Kim's couch. Now she is causing Kim stress. Now she is causing me not to get laid. "Come on, Kim, let me relax you with a nice shoulder rub... and then I'll lick you until you cum." Just a head shake no. I was trying to kill two birds with one stone, but I missed. Kim loves when I talk dirty. Maybe I'll try that. "How about we put on that porn where the Asian chick takes on a couple? The one where her face is covered in pussy juice and it drips off her chin?" Kim is in a phase lately where her fantasy is to have a girl on her face while I fuck her. When I bring it up during sex, she licks her lips in anticipation. But not now. "She's just sitting around. She promised to be looking for a job. I feel like her parent, and I'm sick on not being able to relax on the couch after work. She doesn't even make her 'bed' anymore." It's true. Katie sleeps on the couch, and has been getting sloppier by the day. She started out so clean and neat, picking up after herself. Two weeks later and she leaves her clothes all over the place. She also dresses more scantily by the day. It's summer in Las Vegas, but the apartment is air conditioned. Still, Katie is starting to hang out in panties and a long t-shirt. Kim almost lost it when Katie ditched the t-shirt for a tank top. I guess having your boyfriend around your little sister while she's exposing her tight little ass in cute panties was too much. That, or the low cut tank top that revealed her D cups. I hope Kim is not jealous. "You want me to talk with her? She sort of listens to me. She's just ignoring you at this point." "Sure," Kim replied, "give her a stern talking to I guess. But not now, let's go to sleep. Tomorrow." In 10 minutes, Kim was out. I decide to go to the kitchen for a drink. Water, maybe. Maybe I'll have a beer and watch some TV. Fuck, Katie's on the couch. Man, she really ruins everything. As I head to the kitchen, I hear some movement on the couch. I hope Katie is not bringing guys over to fuck. That's the last thing we need. As I walked past the backside of the couch, I glance over. Katie is sprawled, her legs askew with one up and one extended. The blanket is barely up to her mid things. I see one hand on her inner thigh, right up where the edge of her panties barely covers her lips. I could swear her fingers glistened in the moonlight, but it's probably wishful thinking. As I pull my eyes away, feeling guilty from staring so long, I take a glance at her big, firm tits. Hard nipples poke through the thin cotton of her t-shirt. I feel guilty, but not from checking out such a nice rack. I'm a man, after all. I hesitate coming back out from the kitchen. I definitely hear something now. A slight moan. A wet slurping. "You little slut" I think to myself. She had to know I went by. I drink my glass of water, thinking frantically. I want to take a peek, but I certainly don't want to get caught. Kim is a dynamite girl, and she's a sexual savant to boot. Why screw that up to catch a hot 18 year old fingering herself on the couch? Still, I wait several minutes before heading out. As I stand there, I get the familiar scent of wet pussy wafting through the air. Wow, that's intoxicating. Similar to her sister, but just different enough to notice. Kim tastes divine, and I love when she cums on my face and drips as I suck her pink lips. I can imagine Katie tastes wonderful, and from the sound of it she is sopping wet. As I come back into the living room, I make a slight cough as a warning. Katie is not moving when I look at her, but her panties are slightly askew and I catch a glimpse of the edge of her lips. She is wet, soaking her panties and making her fingers glisten. I take in a big smell as I stare, and as I do I hear her moan. A soft moan, but definitely a moan. I sniff again, and she moans again, this time her lips slightly parting in desire. Damn, Katie is such a dirty girl. As I walk away, I hear the distinct sound of Katie sucking her fingers. I know the sound so well because Kim loves it when I make her taste her own sweet pussy juice off my fingers. I love when Kim does it, and my cock has a bit of pre-cum at hearing Katie do it. One last moan before I head into the bedroom. Kim is asleep, but Katie's little games have left me almost bursting. Kim wakes up to me licking her pretty little pink pussy, lips spread wide so I can get to her little nub. She wakes up horny, and as soon as she's up I push her down and enter her harshly. I smack her ass loudly, and she yelps in pain and surprise. Kim loves to be handled firmly, with a little choking and slapping and hair pulling. I don't hold back when I fuck her, slamming into her as she tries desperately to push her ass up in the air and fuck me back. I usually last a long time, but I'm so worked up by my sexual frustration and Katie's show that I know I won't last long. "I'm going to cum down your throat, Kim!" I yell at her. "Oh yeah, fuck my face and cum in my mouth!" she exclaims, excited by the sudden dirty talk. Man, any dirty talk makes her hornier. "My cock will be covered with your pussy juice when I fuck your face. Lick it all off." I command. "Mmmm yeah I love to taste my pussy juice, baby! Give me that cock!" I pull out of her pink and bring my cock up to her face. She quickly licks all her juices off before taking it deep in her mouth. Within 30 seconds, I am ready to explode. "Swallow my cum, baby! I'm going to cum.. I'm cumming!" I erupt in her mouth, my cock shooting blasts of my seed into her tiny little mouth. Kim's only recently started taking my loads in her mouth, and a little bit slips out of the corners of her mouth and she valiantly attempts to swallow it all. "Oh yeah, that tastes so good, baby!" she cries once she's swallowed most of it down. "I love the taste of my juice and your cum together!" As she says this, we hear a bump in the hallway. "What was that? Was that Katie?" Kim asks. "I don't know" I say, while secretly hoping that it is. "If it is, she now knows how slutty her sister is." "Only for you, baby. Only for you. I'm going to check it out." Kim slides on her panties, and I fall asleep to the hypnotic view of her pantied ass swaying away. I woke up early, and Kim was still asleep. I headed out to find Katie already up. "Coffee?" she asks? I am a little surprised to see her holding a cup out for me. She looks adorable with short shorts, a tiny tank top, and knee-high socks. "Sure, thanks. I'm surprised you know how to make it." As I take a sip, I run my eyes up and down her body, which is turned away to pour herself a cup. The socks are a nice touch, accenting her smooth legs and giving her a naughty schoolgirl look. As if I needed more reason to think about her after last night. Oh, Katie, you're killing me. I sat down to catch a college football preview show. Katie sat on the couch as well, and as I looked over I noticed the same pink and gray striped panties she had on last night jammed in the couch cushions, just a hint of fabric peeking out. Fuck, I would love to get those. No, no, no. I just fucked Kim like she was a whore last night, because she is my whore and she's amazing. I can't be thinking about the cute little panties that her little sister soaked last night. Still, I wonder if she listened to us fuck last night. Throughout the morning, Katie is helpful. She cleans, she cooks, and she is polite. What's going on? For one thing, I swear she's teasing me. Sure, she's cleaning, but must she bend over so far, exposing just a bit of underwear through the leg of her tiny shorts? Or does she have to wipe her hands off on her shirt by rubbing her palms over her tits? Or drop some eggs down her shirt and clumsily retrieve them by almost popping her boobs out of her top? Kim comes out about an hour after I first did, and she immediately notices how clean the living room and kitchen are. "Cleaning are we? After you had no energy to finish me off last night?" I can't believe how open she's being about our sex life in front of her little sis. "No, it wasn't me! Katie did all of this; she's been a real superstar this morning." "Well, she must think a lot of you for her to listen to you. Does every girl just do what you tell them to or is it just girls in my family?" Kim asks. "So, Kim, you always do what he tells you? Anything at all?" Katie asks with a raised eyebrow. "I knew you were listening last night!" Kim exclaims. "What are you talking about? I was asleep last night. Not like I haven't heard you two going at it before, but I haven't for a while. Besides, no one asked me to clean. I decided to help out. And I'm fully clothed!" "Yeah, barely you slut!" Kim teased. "Now, ladies, I'm sure you're both as slutty as you want to be, but I'm trying to watch a show." I say this hoping they will continue. "Whatever, we're going shopping. Come on, Katie, let's see if we can find something for me that will keep this guy awake long enough to satisfy me." Ouch. Fall asleep once, and a thousand pussy eatings disappear, apparently. After the girls are gone, I lay out on the couch and smell something familiar, something delicious. I see the cute little panties that Katie left stuffed in the couch and just stare. My cock starts to swell. I try to look away, but I'm only human. I pull them out and I am almost overwhelmed by lust as I smell the sweet young pussy that soaked them. After a few minutes, I put them back and try to forget about it. Later that night, I again go to the kitchen for a glass of water. This time, I smell pussy as soon as I get to the living room. I see Katie laying on her stomach, a hand definitely in her panties; I can see a little movement at the crotch. Once again I am in the kitchen for a few minutes listening. This time, Katie moans a bit more. I hear her fingers slide in and out almost violently, fucking her little hole and sloshing around her juices. Every minute or so I hear her sucking her fingers and I want to run out and fuck her. But I resist. After a few minutes, I walk out. This time Katie is on her stomach, panties pushed to the side, fingers in her pink slit, and her ass just begging to be smacked. Once again, I wake up Kim with a tongue bath and conclude by shooting a load in her mouth. This time, I talk dirtier. "You're such a little slut!" "You want your pussy juice in your mouth, don't' you?" "Swallow my load, cum slut!" Kim cums as I fuck her, and I cum in her mouth. I swear I hear a noise in the hallway, but this time Kim is too worn out to hear it. But I know. The next night I again sneak out for a drink of water. This time, Katie has her shirt pushed up, her right tit out and her fingers pinching her erect nipple. Her left hand is in her panties, and she appears to be rubbing her clit in circles. Before I can head to the kitchen, she pulls a wet finger out and rubs it around her nipple. Then Katie takes her right tit into her mouth and moans. As she does so, she opens her eyes and sees me. She does not miss a beat, but locks her eyes with mine as she pulls her panties to the side, exposing her dripping pink slit. "Mmmmmm" she moans as her finger goes back to her pussy. She is no longer looking at me, but has her eyes screwed shut. I stand, watching. "I'm such a little slut... I'm a cum slut!" she moans as puts two fingers in her snatch. Soon, her shirt is up and both tits are exposed. She spends some time playing strictly with her tits, her body contorting with pleasure. As she looks at me again, she glances down to my crotch, which is hidden behind the couch. I step around, my dick clearly outlined in my boxer briefs and a wet spot where my pre-cum has oozed out. As she stares at my cock, she reaches down to spread open her pink pussy lips, and I get a beautiful view at her wet hole. Damn, she looks remarkably similar to Kim Kim! I think to myself. I shouldn't be staring at Kim's 18 year old little sister masturbating. I take one more look at Katie, her pussy spread open and thrust up off the couch, and head back to the bedroom. This time, I awaken Kim by rubbing my cock on her face, putting pre-cum on her lips. We end up in a 69, with my cock erupting in her mouth as I clamp down on her clit. She cums as she swallows, and I drink up her dripping juices. "I think Katie needs to get fucked." Kim says. "What?" "I found her panties in the couch. They were... let's just say she was definitely having a good time with them. Didn't you notice it's smelled like pussy out there for a couple of days?" "Where did you find them?" I ask. "In the chair. Don't tell me you didn't see the green panties, you horn dog!" Green panties in the chair? I must have missed them. "No, I did not! I always notice yours when they're snugged up to your pussy, but otherwise I haven't noticed any panties." "Well, if she's behaving so well after getting off every night, I need to make sure she doesn't get bored. She needs some dick!" "Ha! I thought it was my commands that made her behave?" I teased. "Oh, maybe the commands made her horny. After all, you know how being bossy to me makes me gush!" In that moment, I was convinced that if I told Kim and her sister to fuck me, I would have them both dripping and ready to go. I love girls that get off on taking orders! The next night, I again went for a glass of water. This time, Katie was just teasing her soft teenage body. Her fingers traced over her thighs. She traced around her nipples through her shirt. She made eye contact with me early, and glanced down. Again, I stepped around the couch and she stared at my cock, held back by my boxer briefs, as she pulled her shirt up and began playing with her tits. She fondled them. She kneaded them. Katie even licked them before really going to town on her nipples. "Sit down, please?" She asked hesitantly. I wanted to say no, but just the she pushed her hand into the top of her white and pink panties. They had little bows on them, and I could see her labia through the thin fabric. I saw down, half reluctantly and half excitedly. Her hand manipulated her pussy inside her panties and I sat and watched, mesmerized. Her eyes were barely visible over her heaving chest, and she would occasionally squeeze and play with her right boob. "Please let me see your cock, sir!" Katie said almost breathlessly. "Please, sir, I want to see it. I will be a good girl if you let me look at your throbbing cock." With that, I froze. On the one hand, Kim would probably be pissed if I showed my dick to her little sister, barely 18. On the other hand, it's just a look. Soon, my boxer briefs were down my thighs, my thick cock throbbing with each heartbeat. Katie sat up on her knees and I instinctively pulled back. "I just want to see it," she said, "honestly. I just want a good look at what you're giving Kim every night." "Be a good little girl," I commanded, "and you can take a close look." She practically jumped up onto her knees, her head bent forward. "I'll be a good little girl for you," she moaned, "just let me look." She was within inches of my cock, her lips pursed in concentration. I noticed one of her hands between her legs, although between her D cups and her shirt I could not see anything. Her breath hit my balls, warm and moist. I felt it on my dick, and a little pre-cum oozed out. "Ooooh!" she exclaimed, "that looks tasty." Her head got closer, but when she looked up I shook my head no. "But I want a taste!" she said. I again shook my head no. "I need to taste something!" she almost moaned. I often compare sexual situations to a roller coaster. There is great anticipation on the way up, and at some point you hit a tipping point. Going over the top, there is no going back, and the ride will be exhilarating and bring you through twists and turns. Just then, Katie brought me to the point of no return. As if in slow motion, she slowly brought her right hand up from between her thighs. I could see her sticky juice like a spider's web between her first two fingers. She first rubbed her juices into her puffy lips, her tongue snaking out and taking a taste. "Mmmmm," went the low, guttural moan from her throat. Her tongue then shot out and licked her first finger, and I could see her juices coat her tongue. "Oh fuck!" I said out loud, unable to help myself as my girlfriend's little slutty sister tasted her own pussy juice. Katie took that as a sign, and she smeared the pussy juice on her second finger on my balls. Before I could even protest, her tongue was licking it up. She snaked her tongue up my shaft and back down, again taking in my balls before moving back around my cock. As she reached the tip, her tongue scooped up my pre-cum and she savored it in her mouth. Never using her lips, just her tongue, she proceeded to lick my cock up and down. My eyes were closed, my head tilted back, and I enjoyed the sensation of Katie's eager tongue. I heard another moan, but it wasn't coming from Katie. Alarmed, I looked up to see Kim, only wearing a blue thong, standing not ten feet away. She was staring at her little 18 year old sister lick her boyfriend's cock. For a moment, I braced for the worst. Kim wasn't even looking at me, though, she was transfixed on Katie. Her eyes wandered from Katie's head to her ass, sticking up off the couch, her pink and white panties taught on her firm ass. Just as Kim started to move slowly around the couch, Katie took my cock in her mouth, her lips touching me for the first time. Kim was staring at Katie's ass. She sunk to her knees, her face level with Katie's surely dripping pussy, covered in only flimsy material. From what I had seen earlier, I knew Kim could see Katie's labia through the material as it hugged her folds. I watched as Kim, almost in a trance, leaned in and inhaled Katie's scent. She shuddered, her hands going to her B cups and tugging on them roughly. She looked at me for just a moment, her eyes almost begging for permission. "Go for it," I say softly, "go for it you dirty slut." I was talking to Kim, but Katie moaned as if I was calling her a slut. What a filthy family. If only Katie knew what was to come. Kim pressed her face forward, and her mouth gave Katie's pussy a delicate kiss through the cotton fabric. Soon, Kim was making out with her sister's slit, her tongue pushing against the fabric and her lips teasing the exposed outer edges of her lips. "Mmmm, yeah," I heard Katie mumble with my dick in her mouth. Kim reached up, and in the slowest undressing I've ever seen, she pulled those pretty little panties off her sister's ass and down her legs. Kim pulled the panties up to her face, taking in the scent, and then tossed them at my head. I caught them, pulling the soaked garment to my mouth and getting just a little taste. Divine. Almost like her sister, but maybe a bit thicker and sweeter. I saw Kim reach out to spread her sister open before sticking her face in. Katie increased her pace, moaning as she got eaten out, the moans reverberating on my cock. I heard Kim's slurping sounds, as if she was trying to suck her sister dry all at once. I looked down as Kim pulled her face back, her bee stung lips swollen with pleasure and covered in her sister's juices. That did it. Kim's Sister the Slut Pt. 02 I sat back on one leg of the sofa, recovering from the most intense orgasm of my life. Just moments earlier, I erupted inside of my girlfriend's little sister, my cum filling her 18 year old mouth and spilling out of the corners. I had watched as my girlfriend, Kim, and her sister, Katie, shared a cum-filled kiss. I felt paralyzed as I watched them grope at each other wildly, Katie fully naked and Kim wearing her usual tight cotton panties. As they settled down into a sort of nipple sucking 69, my head cleared enough to take in the scene before me. Kim's legs were resting at a 90-degree angle on mine, her knees wide, exposing the damp crotch of her panties. I always loved the way her panties seem to be a ½ size too small, clinging to her folds and leaving just enough to the imagination to make me shudder. Her thighs are creamy white, smooth, and probably not quite thin enough for a runway model. They lead up to womanly hips that give her the hourglass silhouette. Kim still has a cute gap that I can see when she stands. Her ass is probably her best asset, at least the best one viewable with clothes. It's tight, apple shaped, and just begging to be spread. Katie was on top of Kim, sucking on her older sister's hard nipples. Kim's areola are light brown, leading up to beautiful hard, sensitive nipples, and they form the peak of her firm B cups. Sometimes I like to alternate sucking on them for twenty minutes, getting her ready to explode at any touch. Her auburn hair was strewn behind her on the couch. Kim's lips, glazed with Katie's pussy juice and my cum, are wrapped around Katie's right nipple. Katie's nipples are paler brown, almost a dark pink. Katie's areola are wider than Kim's, and her nipples are wider and lower, like a plateau as opposed to a hill. Her full D cups look soft as they hang in Kim's face. My girlfriend was in a personal nirvana, her hands squishing her little sister's tits in her face. Kim was practically devouring Katie's young breasts. I wonder how long she secretly harbored the desire to feast on those soft pillows? Katie's skin is a bit darker; she obviously tans or lays out, although she lacks any tan lines. After what I've seen over the last few nights, I would believe that she lays out in her parent's lawn naked. Her flesh has that baby fat glow to it, the girlish softness that seems to trigger a wanton lust in those around her. Her ass stuck up in the air as she buried her face in Kim's tits. It was probably about the same size as Kim's, but with just a touch of sag. Almost a baby fat look, I bet her butt folds over just a tiny bit when she stands. You know, the type where you could hold a pencil underneath each cheek, but in a good way. Katie's full lips are wrapped around Kim's left nipple, suckling like she hungers. Katie's hair is dark brown and straight, although it had a charming bed head look as it sprawled across Kim's stomach. As I lay there, my boxer briefs around my ankles and cock half-full, half-drained, time seemed to stand still. My girlfriend, fresh off catching her little 18 year-old sister sucking her boyfriend's dick, just got done tasting her barely legal pussy and sharing a hot, cum-filled kiss. Looking back, I could almost piece together a puzzle leading up to this moment. A month ago, Kim got the idea to surprise me with the gift of porn. Not just any porn, but 2 girls and a guy porn. I took that as a good sign, of course, because what guy doesn't want to experience such Sapphic delights? She played a video of a young Asian girl babysitting for a young "couple." Pornos do what pornos do, and soon the "wife" was cumming hard on the Asian girl's face, with strings of pussy juice going from pink lips to pink lips. That part always sets Kim off. Well, that, and when I smack her face, or choke her lightly, or talk dirty to her, or smack her tits, or pound her up against a wall... Three weeks ago, after a long week of dirty fucking, Kim started sending me dirty texts. "I'm tweaking my nipples at work and they're poking out I think everyone can see." "The secretary definitely stared at my tits I'm going to flash her my panties." The secretary at the doctor's office that Kim manages is a cute little Latina who dresses very sexy. Professional, but sexy. Her usual outfit, according to Kim, is a tight pencil skirt that shows off her curvy hips, a blouse that showcases her ample cleavage. Is Kim into her or just getting aroused by being an exhibitionist? "I just bent over in front of Rita I think she saw up my skirt." Kim was getting bold. "Don't get fired lol." I replied, half-seriously and half-jokingly. "Mmm conference call with door closed panties around my ankles." At least the door is closed. "So wet want to see?" "Of course, send pics!" I had no illusion that she would actually do it, but within 2 minutes, I had 5 pictures. The first was a view of pussy, her tight lips mostly closed and a little hint of dew near the bottom of her pink slit. In the second, she was pulling her lips apart with her right hand. The third picture showed her pushing 2 fingers inside. She must be really wet; usually it takes a few minutes to work a second one in. In Kim's fourth picture, her fingers were out and a little string of juice went from her fingers to her pussy. The last picture, though, was amazing. I saw her wet, sticky fingers getting licked by her pink tongue. "So tasty, you want sum?" Of course I did! I sent her pics of my cock, now hard and throbbing. She especially loved the picture that showed some pre-cum sitting on the tip. "mmm I want to lick that up give me a taste!" I hope she's not missing anything on her call. "Come over to the office at 6 exactly!" She texted. It was 4:30, and that last hour before I left work (early, I'm not missing an invitation like that!) seemed to last forever. Kim sent me more pictures, including her wet panties laying on the floor, a sticky spot clearly visible. I arrived 5 minutes early. "Is Kim available?" I ask Rita, noting her curves as she walked around the counter. "No, sir, she's on the phone, sorry. I think she will be done soon. What are you doing here so early?" "I, uh, want to get an early start on dinner. I figured I'd meet her here. And I've told you, you don't have to call me sir!" "Habit, I suppose. Sorry, sir, won't happen again, sir." I laughed. "Okay, okay." "Where are you guys going to dinner?" This small talk is going to catch me up in a lie if I don't stop thinking about sex and start thinking clearly. What I wanted to say was "I'm going to dine at Kim's juicy pussy and fuck her for desert!" But that wouldn't be very, um, polite. Or appropriate. Still, the thought crossed my mind, and I understand Kim's desire earlier to be bold. I wonder if Rita really noticed. "Just Ray's. Nothing that special." "Ah, okay. Kim seems really eager to see you; I think you two will have a fun time tonight." Innuendo or just playful banter? I really want to keep playing up the game, if that's what it is. The flirting is quite a turn on, to be frank, and I'm already on edge from Kim's pics and texts. "We will. We've been looking forward to this all day. Dinner, that is. I'm starving, I can't wait to get tasting." "You make we wish I had a dinner date tonight." Rita replied. Did she just insinuate she wants to get fucked? Well, I mean, who doesn't? I hope that she goes home and fucks herself hard. Or calls over her friend with benefits, or puts on a peepshow for a neighbor. "Kim's off the phone, I'll walk you over." I follow Rita as her ass sashays down the hall. She has nice calves, I notice, before my eyes lock on her firm butt. She could probably break walnuts between her ass cheeks, and I would bet she is not an anal virgin. Something about her just suggests to me that she loves it a cock buried in her naughty hole. The door was closed as we arrived. Rita knocked, and Kim invited us in. "Rita, hey, glad you're here! I have a couple of projects for you. Just a second, babe, I won't be long." As the ladies huddled over some documents, I noticed a faint hint of pussy in the air. Mostly, I smelled some faint perfume, but definitely some pussy. Did Kim try to cover up the obvious aroma? Oh, Kim, how dirty you are! Rita was bent over slightly, leaning in towards Kim, who sat in a chair. I watched Kim's eyes flick down to Rita's ample breasts every few seconds. I hope I'm not that obvious, but I probably am. What can you do? Looking around, I see Kim's panties on the floor, right underneath her seat. Nice cover up, Kim, you missed a spot, I thought. As the ladies were finishing up, Rita looked down. She definitely noticed the panties; I saw her shoe poke at them just a little bit. As Rita walked out of the office, she looked directly at me. "Have a good time, sir. Don't wear her out too much." She winked as she sauntered past, and I turned and made no attempt to hide my stare at her derriere. Closing the door, I turned to Kim. She was sprawled in her chair, her hands feeling up her breasts through her shirt. "I've been waiting for you all day, baby! I need you to touch me. I need you to lick me!" I walked over and stood behind her, my hands plunging into her shirt and groping roughly at her tits. Her head turned and kissed the bulge of my pants lightly. "Yeah, baby, I've been a bad girl all day long." "I think you're naughtier than you know. Your panties are on the floor. Rita saw, you know." "Oh, no!" I couldn't tell if she was genuinely alarmed or secretly excited. "How do you know? Did she react at all?" "She poked at them with her foot; there's no way she missed them. She gave me a wink on the way out. She definitely knows we're going to be fucking in here." "Mmm." Kim shuddered a bit, maybe from the thought of Rita knowing or maybe from me tweaking her nipples. "Did I tell you I flashed her earlier? I think she noticed my hard nipples through my shirt, so I managed to bend over enough where my skirt popped above my waste. I think I was even wet when I did it." "You're such a bad, bad girl." I spun around her chair so Kim was facing me. Her tits were hanging out of her shirt, and her skirt hiked up so high that it barely covered her. Kim's lips parted slightly in lust. I rapped my hand sharply (but within the bounds we had established the previous month as playful) across her face. "Acting like a slut in front of your secretary!" Another slap. Kim moaned. "Your pussy is on fire and you can't control yourself, can you?" This time, I twisted her left nipple. "Mmm... no, sir, I can't control myself. I am a litle slut!" When Kim said "sir" I had an image of Rita's red lips and heaving bosom, her eyes looking up at me as she leaned back on her knees. "I can't control my pussy, it just gets so wet and horny. Please lick me! Please make me cum!" Kim is so hot when she begs, and I'm not sure if I've seen her hornier. "Does this bad girl deserve a licking? Why would I want to lick my little slut?" "Because I'm so wet and tasty. Don't you like my tasty little cunt?" Cunt! I've never heard that word out of her mouth before, and, frankly, it's not my favorite. But in the moment it's so dirty coming from her mouth. "Are you so tasty? What do you taste like?" Kim recently got into this game because she knows how much I like it. Really, though, I think she likes it herself. "Let me show you, sir, how good my pussy tastes." Kim pulled her skirt all the way up and scooched into a slouch on her chair. She brought her right foot up on the chair, knee high up. Her right hand reached around her ass and pulled her pink lips apart. She knows what I like. I saw a little stickiness string between her opening before she pushed two fingers of her left hand inside her. Kim made a scooping motion, probably to rub her g-spot. She moaned as her fingers worked, and her eyes closed in pleasure. I could hear the familiar sloshing sound of wet pussy being penetrated. When Kim pulled her fingers out, she held them up for me to see. Wet. Sticky. They smelled wonderful. Taking her first finger, she licked each side, moaning as she did so. "Mmm, it tastes so good. I love how my pussy juice tastes. Do you want some?" She asked, holding out her middle finger. I took her finger into my mouth, savoring the familiar taste. "You are tasty, and I'm going to tongue fuck you, my little slut! Get undressed" I commanded. Kim likes a commander. As she finished removing her clothes, I took off my dress shirt, stripping down to just dress pants, shoes, and a belt. I cleared out a spot on her desk. "Get on your hands and knees, girl, and spread that pussy for me." Kim complied eagerly, sticking her tight little ass in the air. Face down, ass up! She reached back around her left ass cheek and spread herself, revealing not only her pinkness but her tightly puckered asshole. One day I'm going to fuck that ass, I thought. But not now. I leaned in and blew on her, causing her to shudder. "Please, please, please, I'm such a horny little slut I need to cum! Eat me finger me fuck me make my cunt cum all over your face oh please oh please!" Kim was really begging, and I loved every second. I started by sucking on her lips, getting off every bit of her sweet nectar. Next, my tongue traced around her hole, avoiding her clit. I then straightened my tongue and pressed it slowly into her hole. Pulling out, I retracted my tongue and enjoyed the thick juices I found inside her. "Mmm, I'm such an insatiable whore, I need more I need to cum so hard! Eat my pussy! Taste my pussy. I want to taste my cum on your face!" I decide to satisfy her. I make out with her lips, my tongue darting around and inside, occasionally brushing her clit. I move my mouth over to her clit and gently suck on it, two fingers driving into her and finger fucking her slit. "Mmm... yeah fuck my dirty little hole!" "No more instructions, slut, you cum when I want you to cum." I emphasize my point by putting my juice covered fingers in her mouth as I suck hard on her clit. Kim moans deeply as I force her to taste herself, not that she minds. After a few minutes, I pull my fingers out of her mouth and switch my position. I rub my thumb over her clit hard, knowing that Kim is close to climaxing. I park my mouth over her opening and work my tongue inside again. Kim pushes back hard, practically jamming her pussy into my face. I feel her build up, her moans coming in louder and deeper, more guttural, as her orgasm approaches. "Oh yeah, eat my pussy! Eat my cum! I'm cumming, baby! Ohhhhhh!" Her torrent of juices hit my mouth, a warm sweet (and slightly bitter) concoction that I crave. It gets in my mouth, and some drips off my lips to the desk. I pull my thumb off her clit after a few; I'm not a monster. Kim remains in her position for a few minutes recovering. I lean in to kiss her, and she licks my lips. Slowly, languidly, her tongue explores my mouth and tastes herself. As I stand up, I notice a little puddle of her juices is on her desk. Kim stands up, then pushes me back in her chair. I feel that the chair is slightly damp; Kim's slit was drooling in it for a while. Kim, now on her knees, wastes little time pulling off my pants and boxer-briefs. Her energy and enthusiasm back, she licked her lips at seeing my hard cock. "You have such a beautiful dick," she says, grabbing it in one hand, "I just want to feel it on my face." Kim made out with my cock, her lips kissing and rubbing all over. She moved down to my balls, delicately licking and sucking as her right hand pulled my dick against her face. Kim was rubbing her face on my cock, just enjoying the heat and hardness. As a bit of my pre-cum oozed out, she delicately took it into her mouth. For some reason, she savors those little bits of semen. As much as I love Kim's slow play, I am almost bursting and craving her talented cocksucking skills right about now. "Suck my dick, Kim, suck it like the fucking slut you are!" No woman I've ever met gets off more on being told, harshly, what to do. Kim wasted no time in putting my pole into her mouth, her tongue swirling away around the head. As she begins to bob, she takes it in a little deeper each time until I'm going into her throat. I grab the back of her head and push her down; she purrs in appreciation. I only give her a few minutes before I pull her off; I want to fuck her. "Get up here, you little cocksucker, and ride me!" Kim slithered up my body, leaving a trail of licks and kisses as she went. As we kissed, she lowered her hot snatch on me and started grinding. My hands grabbed her tight ass and helped push her down further with every thrust. I felt Kim's tits pressed against me, hard nipples rubbing against mine. I lean in to suck on her neck as she talks. "Fuck me, baby, fuck this little pussy up! Pound that pussy, make it yours." I don't think I can last much longer, but I want to fuck her more. Looking for an alternative, I see the little pool of Kim's juices on the desk, glistening in the office fluorescent light. "Get up," I tell her, "and bend over with your hands on the desk." Kim complies, but she's far too upright. I push her head down to the desk and pull her ass up. "Show me where you want to be fucked." I say. "Show me where you want my fat cock." "Right here," she says, reaching back to spread her pussy, "pound that pussy, baby, fuck that cunt!" Wow, again! I take her invitation, easing into her hole. As soon as I'm fully inside her, I start to pound hard. She lifts her head up to start to say something, but I push her head down to the desk again, this time facing left. She can probably see her little pussy juice puddle. "You want that, don't you?" I ask her, watching her eyes look at the juices. "Oh yeah, I want that! Let your little dirty girl have it!" I begin to swirl a finger, wet with her juices, near her asshole. She's normally so squirmy and does not like it, but she offers only token resistance. "You want it so bad." "I need it!" "You can almost taste it, can't you?" As I tease her, my finger is swirling around the outside of her puckered hole, and I feel the resistance of going in. "If you want it, you have to earn it like a dirty little girl. You know what dirty girls do?" "They do anything!" She exclaims, moving her face towards the puddle of pussy juice. I grab her hair, leaving her mouth right above where she desperately tries to lick. I hold her there, and I notice my rhythm, my push, has waned. I start to pound her hard, my balls slapping, my finger putting slight pressure on her asshole. Each thrust, I see her tongue lap up a teensy-tiny bit of her juices, probably cold by now. "That's right, you slut, you'll do anything. I'm going to cum all over you." I push my finger, slowly, two knuckles deep in her tight anus as I push her face at the same speed towards her girl cum from earlier. As I watch her lick up her own cum like an animal, I feel pressure building in my balls. My cock starts to swell, and I feel like consciousness is slipping away. "I'm going to cum, baby!" I yell at her, not caring if anyone is working late at the office. "I'm gonna cum!" "Cum on my face! I want you to cum all over me!" At the last second, I pull out and Kim hits her knees. Her mouth is instantly on my cock, sucking with an eagerness I can't even fully appreciate. Just before my first spurt, she pulls my dick out and strokes my cock, her mouth open and waiting. I shoot my first spurt mostly into her mouth, some hitting her chin. The second shot hits her cheek. I aim the rest at her tits, watching as she rubs it into her firm breasts. Kim swallows what's in her mouth, and licks the rest off of her fingers. Wow, if only Rita could see that, I think to myself. Why did she pop into my head just then? Snapping back to the present, I see Kim and Katie sucking on hard nipples, hands roaming across soft flesh. They both have to be just dying to be touched, their pussies throbbing with pent up desire, but neither was making a move. Perhaps the fact that they are sisters is giving them second thoughts. Kim eagerly ate her sister's pussy, but that was in the heat of an electric moment. For me, knowing they are sisters gives it a little electric spark. For them, it's probably the opposite. Kim's Sister the Slut Pt. 02 I need to think of a way to make sure this keeps going. Already, I see a bit less of the chaotic energy that engulfed them when they shared my cum, and a bit more of a slow-burn make-out session (albeit almost naked, and with double tit-sucking, but still). Think, think. What could make them lose control and devour each other? "Kim, you love sucking on your little sister's titties, don't you? Those eighteen year old tits squeezing your face?" I see Kim squeeze her thighs slightly, her butt lift up just a tad. "Your slutty sister's pussy was just dripping all over your face, wasn't it? You like that taste?" I barely hear Kim's moan; it seems a bit subdued or muffled. D cups might do that. "Katie, if you want some more cock, show me you'll please your big sister. Give her that wet tongue you gave me." Not much of a reaction to that. "You want to taste your older sister, don't you? She tastes amazing, get your face in there." Katie picked up a bit at that. "You two sluts are sucking on your sister's titties! Look at what fucking dirty girls you are! You want your sister, don't you? You want to lick it all!" "Mmm... I heard from Kim. Katie moved her mouth slightly down Kim's stomach, her fingers running up and down Kim's smooth thighs. Kim's mouth moved from Katie's huge tits to her soft stomach, but her hands stayed latched on to her breasts. As Katie reached the top of Kim's panties, she placed a light kiss on the little bow at the top. Her hands gripped the waistband on the side of Kim's hips, and Kim gave a slight lift of her hips... Continued in Part 3. Kim's Sister the Slut "Suck his cock you little fucking whore! Get that cum and share it with your slut sister!" Kim has such a dirty mouth. My balls swelled up, my body stiffened, and I started to cum in a huge wave. I stared at Kim, her mouth covered by her sister's juices. I smelled Katie's panties. Mostly, I felt that hot, young mouth as I shot rope after rope of hot cum in Katie's mouth. She could not hold it all, and as she stood up it dripped on her tits. Kim was over in a heartbeat, her mouth licking her sisters firm D cups titties and lapping up my cum. They shared a dirty, cum filled kiss, tits pressed together as they grabbed and groped each other like sluts on a rampage. As I began to recover, I watched to two sisters suck on each other's tits in a 69. They started sliding down each other's bodies, Katie's big tits on top scraping down Kim's stomach as she kissed towards that sweet little pussy that I love to eat. More to come in Part 2.
