Cassie came home from her job at Starbucks in the afternoon.
"Jake? Miranda?" Her roommates weren't home yet. Good.
Cassie was twenty years old and a virgin and didn't believe in sex before marriage, but she still had sexual urges. All afternoon her pussy had been tingling. She'd even been brazenly flirting with some of the male customers, something she'd never normally do. But now she was home and could relieve herself.
She went into her room and was about to close the door, but then she thought what the heck and left it open. Even though no-one was home, the open door made it more exciting. She took off her clothes in front of the mirror, admiring her naked self. Then she lay down on the bed. At last.
She placed one hand on her tit and started rubbing in circles around her nipple.
"Oh yeah," she muttered. She placed her other hand on her other nipple and spread her legs a little wider. Soon both her nipples were very erect. Then she put her right hand onto her pussy and started massaging her clit. This felt so good and so right.
She closed her eyes and pushed her pelvis forward. Then she took her left hand off her nipple and pushed one finger into her dripping wet pussy. It felt so good the moment it was in there.
She spread her legs as far apart as possible and stuck another finger in. She began pumping them in and out of her.
"Oh oh," she murmured. Then she remembered there was nobody in the house and began groaning and moaning louder.
It didn't take her long to climax, and when she did she felt her pussy juices flow all over her hands like the waves of pleasure flowing all over her body. She took her hands out of her pussy and put them in her mouth. She tasted her juices.
"Mmm," she licked her fingers clean.
She felt tired then, so she turned on her side and went to sleep.

Jake stood in the doorway, his hand frantically jerking his cock in his trousers. He couldn't believe what he had just witnessed.
Cassie turned her key in the front door, expecting her love to rush to greet her as usual when she was home first. Laura had had an important shoot with a big client this morning and had decided to leave the rest of her day free allowing her to come home put some music on, and get on with the editing. Cassie pushed the front door open, puzzled by the lack of an excited Laura bounding down the stairs, she always ran down to kiss Cassie to welcome her home. Cassie could here music. She must not...
The work day is finally over and I can’t wait to go home and take a nice long shower. It has been a long week and I am so glad it’s finally come to an end. I have not been able to think of anything but my night with Jacob. It has been 2 weeks since our last encounter. I replay that night over and over in my head making myself so wet just at the thought. Each night there has been a note taped to the inside of my private elevator door from Jacob telling me about all the things he wants us to do...

My mother and dad had divorced, dad was gone and we lost the house, well apartment really. Mom had moved in with her brother Uncle Mark.

Well my name is Cassie and this is about my first time, it’s been a long time since then but I still remember it vividly and quite fondly as well too! My mother and dad had divorced, dad was gone and we lost the house, well apartment really. Mom had moved in with her brother Uncle Mark. I guess now in retrospect I should have seen the things that were wrong back then but at the age that I was and the sheltered upbringing that I had, well I guess I just hadn’t figured things out...
Well Mom never did “deal with me later” that caused me to start thinking. I remember all the fights as my parents broke up. One of the things my dad had said was “you’re in charge of everything, but aware of nothing” I now realized what he meant. As time went on I only became even more and more aware of it. That was a Thursday that the most spectacular day in my life had taken place on. Friday turned out to even be better. Mom bitterly announced that night, when she was supposed to be dealing...
CONTROLLING THE URGES By Charles E. Campbell Control. Looking back, I guess that's what it's always been about. Really about. Control.It's control over me. My control over it. When it would start. Keeping it incheck. What it would require of me to appease it. How long the urge would last.Keeping it as a long held private secret. Mine only. To know and fear, andyet, embrace. All of these things, and more, it has been for the better part of forty-fiveof my fifty-two years. But now, it is...
Secret UrgesBarefoot RunDave, a 13 year old eighth grader, grew up before there was an Internet and only a couple primitive computers existed in the whole country so he could not Google or search JackinWorld to discover what was happening to him and the dark urges he felt. It was before HIV. It was a time when schools did not teach sex ed and before gay lib made alternate lifestyles thinkable. Dave's parents like many parents at the time would not talk about sex and he couldn't dream of...
The earthquake lasted several minutes. That was all the time that was needed to bring down most of the houses in the neighborhood. Almost every other home was reduced to ruble. When the shaking started, Frank was up on a ladder painting his house. The vibrations almost knocked him over. He was a very muscular man and was able to hold himself in place against the house as the ladder teetered and swayed along the gutters of the roof. Being a fireman had its advantages and staying steady on a...
Robert Livingston had been a widower for about six months. He and his wife had been completely devoted to each other, and not once in their twelve years of marriage had either been unfaithful. "Compatible" is hardly a strong enough word to describe their relationship--their interests were almost identical, and they were truly friends who cared about each other. They were extraordinary lovers, too. They liked to do just about everything, with no guilt or embarrassment even when they sometimes...
Unholy UrgesbyStardog Champion©Thank goodness for the trace of warmth emanating from the computer screen on her cheeks because the rest of Kay Kellerher's body was growing clammy and numb. Even though it was late Summer and the humidity that plagued the Florida panhandle hadn't shown the slightest hint of letting up, the 47 year old woman might as well have been sitting on a chair of chisled ice as she stared, eyes agape, at the computer in front of her. "Please... nobody come upstairs," Kay...
Anna Morgan awoke knowing things weren’t right.That ache, low down. Different from the ache from her monthlies, which were at least two weeks away. Under the bedsheet, she was naked.No! She never slept naked.And why was she damp down there? Down in her dirty parts.Anna sat up and saw her pyjamas slung over a nearby chair.From downstairs came vague noises, one of them the chugging of the kitchen tap. She’d meant to have that fixed. Crazily, she connected the sound downstairs with her lower body....
Fantasy & Sci-FiI was no virgin. No amateur at this. I knew what I was doing. I may only be young but I knew damn well what to do. Knew how to pleasure myself and turn others on in the process. I looked into Joe’s eyes, saw lust and pleasure. He’d already cum twice, yet he still had a boner and was going for it again. I knew instantly he wouldn’t mind. So I laid back down and shoved the brush into myself. Pleasure and pain hit me simultaneously. I began to thrust the handle of the brush into...
Hello fellows, I am Sheela, a 53 years old widow with strong sexual urges. I am a mixed-race woman. My father was an Indian man, while my mother was a British woman. I married the man I loved with all my heart and soul, but he, unfortunately, passed away. Together, we made 6 babies before my husband’s untimely demise. As of now, I am a mother of 16 children (all mine, none adopted). But with yoga and gym, I have managed to keep myself in shape. I was doing the laundry one fine morning when I...
IncestDAUGHTERS HORNY URGES“This is perverted”, f******n-year-old Jessica told herself as she crept along the darkened back hallway of her house, moving closer to the soft moans coming from her parent’s bedroom. It was almost one o’clock in the morning, and Jessica, clad in her flimsy powder blue nightshirt had been fighting the urge to peek for ages. Images of being caught peeking flashed into her mind, the outrage of her parents, the embarrassment of being caught. But other images flashed into her...
a****l URGESI Awakening Upon awakening, my first sensation was of nausea. The difference, from the prior three occasions, only manifest in degree. Yet I did not have to open my eyes to know that, as before, I lay naked and covered in blood – hardly any my own – that was largely dried, especially around my face; eyes crusted shut, mouth tasting of blood, vomit, and I-dared-not-think what else. Not to mention the other vile bodily excretions in which I lay. Despite my being largely u*********s of...
A special thanks to KillerMuffin who worked long and hard editing my script. It was her Herculean efforts that made it as readable as it is in its current state. I accept responsibility for all the remaining spelling mistakes and poor grammar. I simply can't read it one more time. Idly, I reach across the desk and flick my index finger against the quartz desk clock and penholder. In spite of this stimulus, it does not increase its tempo, but rather continues its slow, methodical beat on this...
The first woman I ever found attractive was Catherine Zeta Jones and that crush has stood the test of time. Although I never copied it down in my journal, I remember watching The Haunting released 1999 in our exercise room. I sat on an exercise machine that felt like a piano bench cushion in the unfinished room. I watched the actress’s entrance up until this line:“So what about you? Husband, Boyfriend, Girlfriend?”Her last word was accompanied by a mischievous smile at the camera with her brown...
TrueA few months ago I was at a pool bbq party at my sister-in-laws house. My wife had always been close to her sister Mary, so we often found ourselves at eachothers homes on the weekends for various functions and get togethers. My wife, Miranda, is a beautiful woman, at 5’1” tall she had a glorious figure. Nice full C cup breasts, dark brown hair hanging past her shoulders, strong legs, a flat stomach and an ass men would kill for. Mary was a little shorter than my wife, with blonde hair and...
"Mark, not again!" I scolded Mark. His eyes were leering again at the checkout clerk. She was roughly 21 give or take based on her long blonde hair tied back behind her grocery store hat. Had a short top on underneath the apron, and thin tight jeans. Mark gave me a look of embarrassment. I just gave him away and called him out again. My head ached again. This was the third time today, earlier I had whispered when he checked out the brunette coffee babe as she handed him her coffee. I looked...
TranssexualJay knew from a young age. After finding that “Playgirl” magazine in a field near his house, he knew. As his eyes excitedly washed over the photos of nude men, he could sense his desires welling up, he could feel his attraction and lust swell his cock within his pants. Jay had seen naked girls in magazines before and been turned on, but this was something different, something altogether more powerful. He was drawn to the cock’s in the pictures. He found them beautiful and sexy, yes, but it was...
Older Men & Younger UrgesIt was an odd thought for a girl who had travelled the universe, gone through space and time, but the engagement party of Clara's friend, clearing out the local pub and filling it with music and shouted conversation, was proving too lively for her. She thought to go outside to clear her head, but first she ducked into the bathroom.There was a grimy feel to the inebriated air and pounding music, enough to make Clara sweat, and she wanted to quickly wash up before she...
Daddy Urges by rdwriter©Tom was looking at the vacation pictures his wife had sent him. Scrolling down the email screen he saw one with his daughter at a beach in South Florida. Jenna was wearing a hot pink two piece bikini. He found himself staring at the picture scrutinizing every inch of his daughter's body, he had not seen her with so little clothes on in a long time.Tom rarely had any sexual thoughts about Jenna but now realized she had blossomed into a very attractive 18 year old teenager...
Urges and Purges Being a crossdresser is kind of like being a ping pong ball in the gender game. As we go through our lives in guy mode the need to crossdress can come on like a tidal wave. Depending on our individual circumstances this urge can be quickly and easily addressed or might have to be sublimated indefinitely until the convergence of motivation and opportunity arrives. I think that many of us deceive ourselves and try to deny the urge to crossdress but despite all the...

It was a little after seven when my iPhone buzzed, letting me know I had a text message. I had it set on silent ring, since I was studying in the university library, which had been my practice for the past several weeks. Courses were getting much more difficult since I'd gotten into my major. The first two years were a breeze, but now I really had to study.The text message was from my sister, Cassie. She's in her first year at the same university where I'm a third year student. We're only one...
Cassie and Wendy Find a Maid Author's Note: I decided Cassie and Wendy (from Meteor Strike) needed more than their brief appearance in that story. Seemed like I could make several people happy with this! I hope you enjoy it. Cassie woke up Saturday morning feeling a bit depressed. She had spent the previous night trawling the bars looking for someone to bring home for some sexual calisthenics but nobody that she found interesting enough was available, and the ones that were available...
I had just discovered that my k** sister schemed to get me to have sex with her because she wanted to have my baby. She had been charting her ovulation for the past several months, and knew that she was fertile this particular weekend, so she got me back to her apartment for sex. After discovering her plan, I confronted Cassie in the kitchen, where she was preparing dinner. Cassie, still nude, slowly walked over to me and placed her hands on my shoulders. "You remember a few minutes ago when...
Nearly two weeks after Zack and Ellen moved into their new apartment there came a knock at the door. It was a bit of a surprise, since their place was at the end of a two-story building and offered a nearly private entrance for them and the one other apartment on the end.“El, can you get that?” Zack called from the second bedroom. He was attempting to assemble a TV stand and desk in what was going to be an office for him.“Okay!” Ellen dried her hands and went to the door. She glanced toward the...

Chapter 2 Crashing Bobby’s Birthday Party Written By: Mr. Mongo Cassie left the homeless man in her dust as he still held onto his pecker. She laughed to herself at the thought of that. Now is the time to try to figure out where she is. Cassie knows the mall is at least ten miles from her house, she had run that distance before, but that was with sidewalks and the roads fully clothed.

Chapter 1 Stripped By Miss Piggy Written By: Mr. Mongo Despite a bad head cold Cassie took a shopping trip to the mall on her Fourth of July vacation. She hoped to take advantage of the fact everyone is at the beach or barbequing in his or her backyards it gave her a near empty shopping mall.

Before being married, I was living in a house with two artist students. My then girlfriend lived in her own house share. Ours was a very large house with spare rooms we’d use for studio space, open areas for communal get togethers and all in all we were a happy group of three young guys, committing to our creative lives and generally having a good time. We decided after some time that one of the smaller, unused rooms may as well be used for another flatmate to reduce our expenditure. The word...
Note : This story is completely fictional! Cassie Hole Pt 6 The pool shimmered in the heat, the clean blue water undulating restlessly against the sides of the tiles. Michael worked some business ledgers and the cell phone that was always at his side. The sun that embraced the L.A. mansion that day was harsh and full, the shadows long and high. “Has he been picked up yet?” He asked into the cell. “Good.” He set back the phone, dismissing it and looking at his watch. A good forty-five minutes or...
IncestAn ignorant part of me still persisted: “I’m feeling up a REAL girl’s tits, this was so much better than it was with Cassie”. It wasn’t the truth of course, but I made myself believe it. Gail and I never had sex that day. She was way too nervous to have sex, but I got the opportunity to explore an actual vagina. I’ll never forget the sweet memories I had with Gail that day. She taught me a lot: spots to pay attention to, how to finger a girl, and a ton of foreplay. They say you never...
Note : This story is completely fictional! As she waited there on the floor, she could sense them collect themselves, pulling up their pants and zipping up and quietly move out the door. She stood and went back to the living room and checked her sluttish face in the mirror and gaped in the last few strings of jizz onto her tongue. She made her way upstairs and went to the bathroom to prepare herself for HIM. As she stepped out of the shower the phone rang and she flung herself over the bed as...
IncestCassie McCaffery nearly dropped her coffee cup when her best friend made his request. "Th-Three way?" She gasped, putting the cup down with a shaking hand. "You have got to be kidding!" Mark Benson grinned wickedly at his childhood buddy. "Cass, I thought you'd be overjoyed!" The busty redhead felt her face grow warm. "Overjoyed, he says?" She took a deep breath. "You can't be serious! Tracy is my friend too! She isn't just my roommate! She's also your fiancée! She'd hate us...
Note : This story is completely fictional! Cassie woke up and reached for her Daddy, Michael, remembering HIS fat cock after her tease with Salazar, her perfect posing cunt candy opened to Daddy’s business partner, wanting desperately to have Salazar fuck and use her for HIM, because she knew Daddy wanted that. When HE interrupted and all Cassie got was a hot thick juice load on her face, and HE came in then took her back and fucked and abused her tender fuck holes, she just smiled and thrilled...
IncestCasandara Wilcox stepped out of the shower and stared at her image being reflected back to her in the full length mirror on the back of the bathroom door. Most women would kill to possess the feminine attributes Cassie took for granted, large heavy breasts, a flat wash board stomach, long lean legs, a tight but full bottom, a lovely face framed by medium length brown hair, and of course a large lipped succulent vagina! After twenty three years, however, Cassie still sometimes broke down crying...
Introduction: Must read part one first As we were laying there recovering from the best orgasm ever, I asked Cassie when was the last time her mom kissed her down there. She told me that when Tracie and her moved in with me. She told me we couldnt do that anymore because I might find out. If I found out I would have Tracie put in jail and she would never see her mom again. As I was laying there thinking about what Cassie just told me, Tracie called to let us know she would be home in about an...
Cassie's day couldn't get any worse, she had flown halfway around the world to see her boyfriend who was studying in England, and she had found out that he was sleeping with a girl on the same course. Needless to say she had packed her bags and walked out. So this was how she found herself walking alone through the streets of Leeds with no idea where she was going or what she was going to do. The first thing she needed was a drink and a bite to eat. Across the road was a wine bar that served...
LesbianCassie was a looker. And she knew it. She had that kind of look that turned men’s heads when she walked down the street, and she always dressed to get attention.Her usual style of dress was either skin tight trousers, high heels that made her long legs look even longer and slimmer, and tops that did little to hide the swell of her breasts.If it wasn’t the trousers, it was mini skirts. They didn’t actually display the pleasures hidden beneath, but every man I know would have done anything to...
If you asked Cassie now why she started it, she would probably not be able to give you a straight answer; it seemed it was just something that happened of its own accord. It wasn’t as if she didn’t have a great sex life. Indeed, for a fourteen-year-old her sex life was amazing. Her Grampa had been fucking her and licking her puss at least four times a week for several weeks since she went to live with him while her Mom and Dad tried to sort out their marital problems and he gave her at least...
As I was laying there thinking about what Cassie just told me, Tracie called to let us know she would be home in about an hour. I talked with Cassie some more about what just happened. I told her she must never let anyone know what we just did not even her best friend or she would never see her mom or me again. She said she understood and wouldn’t tell anyone. I then asked her if she would like to do what we did again but have her mom join us. She had a grin on her face you could see from a...
Note : This story is completely fictional! Cassie and Michael walked into the mall, and she tugged him into a shop called Rave, a hip store that catered to young girls, rather something more than that, a store that specialized in fashion that was on the edge of MTV and the more subtler side of porn, some of the sunglasses and types of clothing actually had sponsors like Metro or Anabolic or Vivid Films which he recognized as porn distributors. They went in and Cassie immediately squeezed hard...
IncestNote : This story is completely fictional! Cassie had practiced this. HIS wife’s, her mommy’s car started up and went down the stone driveway, pausing to open the security gates and flowed through. That was the key for Cassie as she moved out of her bed and went to her shower, cleaning the scum that collected on her firm young thighs from masturbating the night before, the gelled dildo still twisted in her bed sheets as she cleaned up and stepped out. She pulled her robe on and sat down to do...
IncestIt was a Thursday night and still being single and a bit lonely, not getting as much sex as I was use to having a girlfriend, I decided to message Cassi to see if she would be keen to meet up for the day. She was indeed keep and as we chatted she said she would meet by my house just after 9 tomorrow morning. She seemed rather excited and we continued messaging each other for a while before saying goodnight. I almost immediately fell asleep after my last message to Cassi. Waking up Friday...
It was my Dad. He sounded half asleep. “His Lordship’s daughter just rang,” he said. “She needs a lift home, Can you get her do you think?” “She’s in town, twenty one A Braithwaite Street.” “Look I got lectures first thing and how’s she going to like being fetched in my Mini?” I asked. He sort of pleaded, “Well your rooms are about a mile from her and I’m twenty five miles away, and I have a six thirty start myself, are you sure you can’t help?” “OK,” I agreed. That was the trouble, dad...
"Oh my god! Jenny! You didn't say he was THIS big!" Cassie, your girlfriend's best friend, only heard good things about you from Jenny. About how... productive you are, especially in the bedroom. Of course, she told you only good things about Cassie. Oh she'd brag about how hot she was, she could be a porn star, especially with her massive tits... but for some reason she didn't show you any of her pictures. You could only idly wonder if she bragged about your cock with the many MANY dick pics...
FetishWhen I look at Cassie Ibiza, my first question is, what hole do I stick it in first? I can tell by her content on Twitter where Cassie would like me to start: her asshole. But holes have long been at odds with one another.The Greatest Debate Ever KnownLet's take this argument orifice by orifice, starting with the mouth. I want all gents on our little blue ball to pat themselves on the back for a job well done right now. It took many moons, but we finally changed human society to reflect the...
Twitter Porn AccountsIntroduction: sorry about the story set up, I don't like giant walls of text. “Knock it off already.” Cassie had the remote control firmly entrenched in her hand and was doing her best to keep it out of reach. The TV was stuck on basketball, which sucked. I knew that there had to be some combination of leverage and brute force that would cause my sister’s fingers to open and let me gain command of the remote. Getting up and walking to the TV was simply out of the question.“Knock what off?,” I...
The strange thing about what happened, between my daughter's best friend and me, was that it seemed so perfectly natural, so utterly ordinary. It was never a destination that either of us chose, but it was a place that both of us were happy to travel to. More than happy in fact, ecstatic - at least in my case. You'd have to ask Cassie about her recollection of the events of last year. Most of all, it didn't seem strange and it didn't seem wrong, though it was clearly the former and more than...

I was shaky when I stood up from the keyboard. Adrenaline coursed through my veins. Her response was swift, arriving before the adrenaline wore off. She didn't know I could be that assertive. After acknowledging her surprise, she played the proper submissive and promised to follow my instructions. We would meet in less than 24 hours. I loved my wife, so I couldn't tell her about my game with Sharon. She wouldn't have understood, but I was merely playing a game. I knew I wouldn't step...
Katelyn and I hired a caterer for her parents' fiftieth wedding anniversary at our spacious home which sits on two acres. Everyone had a good time eating, drinking and dancing. The last guests left at midnight and by that time, she had a steady buzz going from the Sweet Riesling wine she drank. My buzz came from consuming my favorite beer, Hacker-Pschorr Weiss. By one-thirty in the morning, the catering staff had everything cleaned up. As soon as they left, the two of us rushed to our master...

Note : This story is completely fictional! "Mom I'm home i shouted!" I had already come home from college having graduated pre med. I couldn't wait to see my mother. She was a lawyer working for a major law firm. "Honey, you have to learn to stop being impatient", my mom said. I looked at my mom walking down the stairs. She was 42 and had a very lovely body. She had hair, nice legs, firm tits and a sweet ass. When I was growing up I always imagined her as a young Linda Hamilton. I had a hard on...
