Date: Mon, 6 Jul 2015 09:42:44 +0100 From: John McQuillium Subject: Uni mate's 16 year old sister Uni mate's randy little sister part 1. The following is a true account of me having sex with a mate's 16 year old sister when I was 23. It only contains straight sex so if that's not your thing don't read any further Comments gratefully received at johnmcquillium@hotmail.co.uk Usual blurb about don't read if you are underage, etc. Also why not make a small donation to Nifty so they can keep up the good work. Paul and I were mates from our University rugby team. He was as fit as fuck with a hunky body, dam sexy face and big cock. Unfortunately he was 100% straight and a real chic magnet. He knew I had the hots for him and would often tease me by saying things like "I bet you're fantasising about my big cock fucking you now" or flashing me out of bounds fruit. It was all in a friendly teasing way. The gayest thing Paul had ever done was have a threesome with me and a girl we picked up in a club. She couldn't decide which one of us she fancied the most so I suggested she take both of us. Paul was unsure at first but booze and hormones soon wore him down. The poor girl didn't know what hit her when we got back to Paul's place. The biggest cock she'd had before had been 8 inches now she was faced with my aerosol can thick 10 inch cock and Paul's slightly slimmer but still thick 11 inch cock. We tag fucked her twice each with Paul going in first. During the first round she screamed a lot unsure of whether she was enjoying being fucked by two big cocks or not. Her tight pussy had adapted for the second round though with both Paul and I making her cum. After a brief break we then double penetrated her pussy stretching it to bursting point. Feeling Paul's big cock rubbing against mine with her hot cunt surrounding them felt great. Half way through the fuck and my cock slipped out and "accidentally" slipped up her arse popping her anal cherry. At first she wanted me to stop but I didn't and talked her around. The pain of losing her anal cherry to such a big thick cock as another huge cock pounded her pussy didn't last long as she ended up having an earth shattering orgasm that she herself admitted was the best she'd had. Her orgasm made her pussy and arse spasm which set mine and Paul's orgasm off flooding her lithe body with yet more cum. After that I left them to it and they became an item for a while but in an open relationship. Unfortunately the threesome was a one off. In the Christmas holidays of our final year Paul invited me back to his parent's place as his Dad had secured tickets for a rugby game. His family were very welcoming especially Paul's 16 year old sister. Casey was so sexy in a sweet innocently cute way she could turn the campest queen straight. She had shoulder length brown hair with natural blond streaks in it. Her lightly tanned face was flawless and looked sweet innocent schoolgirl cute. She had dreamy hazel eyes, a cute button nose and thin pink lips that always seemed to be turned up in an innocent yet sexy smile. Despite it being an English winter she was dressed for the summer. She was wearing a vest like top with thin shoulder straps with the neckline only just being above the top of her pert perky breasts. The nubs of her nipples showed through the stripped cotton material so it was obvious she wasn't wearing a bra beneath. Not that she needed one as her breasts were about a size 32B and very firm and pert in the way only a teenage girl's breasts can be. She had long slender, lightly tanned arms and dainty hands. Below she was wearing a very skimpy pair of dark blue cut off jeans showing off slender but shapely legs honed from playing hockey. She was dressed like a slut but had the face and body of a virginal 16 year old schoolgirl. As I would later find out just like me when I was her age we used our innocent Dr Jekyll appearances to hide the sexually deviant Mr Hyde underneath. The only time I wear underwear is when playing sport so I was thankful I was wearing baggy cotton tracksuit bottoms as the sight of Casey had me boned up. Paul's Mum and Dad were also quite tasty for 47 year olds so it was obvious where Paul and Casey got their stunning good looks from. The five of us chatted for a few hours before Paul's parents got ready to go to the opera. As we chatted away I was getting more and more certain Casey was eyeing me up and giving me flirtatious glances. However I put it down to wishful thinking and besides she was only just barely legal being 7 years younger than me and my mate's sister as well. It certainly meant I faced a conundrum when it came to that night's obligatory wank as I didn't know if I should fantasise about Casey or Paul. The three of us stayed up until midnight watching films before we went to bed with me in the guest room. Their parents were staying in a hotel after the opera so they weren't due back. After doing my nightly ablutions I wanked off as I sucked my knob fantasying about fucking Casey's tight teen twat with my aerosol can thick 10 inch young man cock. My fantasy switched to sucking Paul's straight boy cock when I started pumping my thick cum into my mouth. Sexually slatted and tired from the long journey I fell into a deep sleep. During the night I awoke feeling my cock warm and moist. Groggily coming awake I realised my cock was being sucked. My first thought was at last I've turned Paul but then I felt hair on my thighs and as Paul's hair is short it could only mean it was Casey. Sure enough when my eyes eventually opened and focused there was Casey totally naked on her knees and elbows between my legs sucking my limp but rapidly inflating cock. From the light of the full moon shining through the window I saw her shoulder length hair swept back with a sexually mischievous cock sucker's grin on her lightly tanned sweet innocent girlish face. Considering Casey was only a 16 year old schoolgirl she sucked cock like a gay pro. She had the kind of tongue that could tie a knot in a cherry stem and she was currently dancing it around my rapidly inflating knob with the shaft of my cock swelling and growing between her soft warm hands. My cock was more awake than I was and it was quickly growing to its full fat 10 inches. Casey was holding my gaze as she bobbed her hot wet sucking mouth up and down the top couple of inches of my big cock and lashed it with her tongue. Seeing such a sweet innocent girlish face doing something so adult and sexual was a real turn on. Seven years back and it would have been me in her position sexually pleasuring someone older. In Casey I recognised a kindred spirit, someone who knew how to use their sweet innocent appearance and in depth sexual knowledge to sexually satisfy someone older. The fact she was a good mate's 16 year old sister slurping away on my big thick 23 year old cock with him asleep next door should have made me stop her but it didn't as she was doing such a good job. Now fully awake and realising what was happening I turned on the bedside lamp to get a better view. Her dreamy hazel eyes sparkled with a sexual mischief that belied her tender young age as did the blow job she was giving me. Her pink lips were stretched to the max around my deeply tanned and eye wateringly thick 10 inch cock as she strongly and expertly sucked it whilst swiping it with her talented tongue. "Wow you have a massive cock, I've never seen one so big." Casey whispered with lustful admiration in her girlish voice as she rubbed her soft warm hands up and down the thick throbbing shaft of my cock. "Thanks and you sure know how to work it." I replied causing a sexy smile to spread across her stunningly cute face. "Kneel up." I added. Casey knelt up so I could admire her flawless schoolgirl beauty. Her shoulder length brown hair framed a stunningly cute, sweet innocent girlish face that was flawless and studded with two dreamy hazel eyes and pink pouty lips. She had firm pert perky 32B breasts studded with two pointy pinkish brown nipples surrounded by small halos. Her body was lightly tanned but you could see the paler area of her breasts that had been covered by a skimpy bikini top. There was a hint of a tan to her breasts so she must have gone topless sometimes but paler than the rest of her. Her stomach was flat and firm and led to a small, sparse but broad bush of brown pubes. The pink fleshy lips of her aroused teenage pussy were already exposed and glistening with love juice. "Wow you are so beautiful." I said as my eyes kept scanning up and down her naked slender but sports toned teenage body. "Thank you and I moment I saw you I knew I had to have you." She lustfully said the adult words sounding strange in her girlish voice. "Maybe this is a bad idea as your brother is next door." I half heartedly said with reason trying to battle with animalistic sexual urges. "He's used to it, he has such sexy friends and I seduce most of the ones he brings over. Besides he sleeps with most of my girlfriends, they think he is such a hunk." Casey said as she continued to gently wank my big thick cock between her petite hands. Mentally I agreed with her but didn't say anything in case Paul hadn't told her I was bi bordering gay. Seeing a randy eager naked 16 year old schoolgirl knelt before me was certainly bringing out my bi-sexual side. Casey had only just turned legal and she was a mate's younger sister so logic should have made her strictly off limits but what chance does logic have over lust. How could I possibly turn down the chance to have sex with such a stunningly cute, beautiful, fit 16 year old girl even if it meant stuffing up my friendship with Paul and being slung out of their parent's home miles from my own. "Spin around so we can 69." I said giving into irresistible temptation. An eager grin knowing she had bagged another of her older brother's friends spread across her cute face. Casey spun around so she was in the 69 position above me. With her schoolgirl sex was above my face its horny aroused teenage scent hit me and I drank it in deeply. As I admired her pussy up close Casey resumed sucking my cock causing waves of pleasure to course down it. Her talented tongue was swirling all over my swollen sensitive knob which was rewarding her with copious amounts of pre-cum. Her hot wet mouth expertly sucked my cock as it bobbed up and down the top few inches before the meaty girth got too much for her. At the same time I took in the sight of her fleshy pink labia tinged with brown and glistening with love juice. At the top was her small bullet hard pink clit. Tilting my head back I saw her firm pert shapely arse which had the pale V of skin from wearing skimpy bikini bottoms. Her pinkish brown arsehole looked small and tight and I wondered if it had ever been licked or fucked. After admiring her schoolgirl sex and drinking in its horny aroused scent I had to taste it. To start off with it was gentle little flicks of my tongue from side to side over her soft fleshy exposed labia. Then I would lick, suck and gently nibble her bullet hard clit making her muffle whimpers of pleasure that reverberated down my big thick throbbing cock that was in her mouth. Then I started really tongue fucking her soaking wet schoolgirl snatch, which was leaking loads of delicious teenage pussy juice. This was heaven and my body was alive with pleasure. There was the delicious taste and erotic smell of a 16 year old schoolgirl's soaking wet sex pressed against my face and nose as I eagerly licked it out. My hands were busy gently groping her firm silky smooth, sports toned arse. At the other end my big thick cock throbbed with intense pleasure from the expert blow job Casey was giving it. Her tongue felt like an electric eel snaking around my bulbous knob as her lips wanked the top of my thick throbbing cock shaft and her left hand wanked the base. In top of that there was the kinky thrill her older brother was asleep next door. For ten blissful minutes we 69ed, our oral stimulation of each other's genitals increasing the lust and sexual tension in us both. It was Casey who let go first. Her muffled whimpers of pleasure became longer and more frequent. Her tight teen body started tensing up and her pussy leaked even more delicious love juice. She endured my tongue fuck for a couple more minutes before the pleasure got too much for her. My tongue was alternating between flicking up and down her fleshy labia to stabbing in and out of her steamy hot, soaking wet schoolgirl sex as I vigorously rubbed her bullet hard clit. Then her sexy lithe young body locked solid and then began to shudder and shake as an intense orgasm hit her. If my big thick cock hadn't been in her mouth she would have been screaming with sexual ecstasy and release as waves of intense orgasmic pleasure coursed through her fit little body. Some girls don't produce much when they orgasm, others dribble but some gush and Casey was definitely a gusher. She powerfully squirted her delicious water girl cum into my open mouth where it immediately fired off my taste buds. My tongue continued stabbing in and out of her quivering orgasming pussy as I rubbed her clit. Her orgasm caused her to stop sucking my cock but it was still in her mouth and her orgasmic muffled moans of pleasure reverberated down it. Her orgasm was so wet it felt like she was pissing in my mouth but my taste bud told me it was definitely delicious girl cum. Gradually her shuddering body came to rest. As Casey savoured her orgasmic high I toned down the tongue fucking I was giving her. Instead of vigorously rubbing her bullet hard clit I gently stroked it as my tongue loving flicked her soft fleshy labia that was soaked with her girl cum. Casey had let my cock fall from her mouth and was resting her head on my right thigh. Casey's orgasm had been so intense it took her a few minutes to recover. When she did of her own accord she climbed off me, swung around and knelt between my strong sports toned legs covered with blond hairs. She gave me such a sweet innocent smile before she resumed her skilful blow job. It seemed impossible that such a young innocent looking face could be as skilled in the art of fellatio as Casey was. Seeing her sweet innocent virginal girlish face doing something so adult and erotic as sucking on the end of my big thick manly cock was such a turn on its own let alone the wonderful physical pleasures her talented tongue and strongly sucking mouth were lavishing on it. The erotic sight, the physical pleasures, the satisfaction of making her orgasm, the lingering taste of her pussy and girl cum on my tongue, its arousing aroma and the kinky thrill that she was seven years younger than me, barely legal, with her older brother asleep next door meant that I could only endure another five minutes of her expert blow job. Despite my pre-bed orgasm I could feel her skilful blow job had built up another massive load in my balls. Not many girls like the taste or texture of cum and even fewer let you cum in their mouth so I whispered a warning to Casey I was about to cum. Rather than pull away she started sucking and wanking my cock harder. It was like looking at a mirror back in time. Seven years ago I would have been the 16 year old knelt between a man's legs eager to have them cum in my mouth. Now the tables had been turned and I was the man but with a 16 year old girl between my legs eager to make me cum instead of a boy. If Casey wanted my cum she was about to get plenty of it. Her hot wet strongly sucking mouth and tongue snaking all over my swollen sensitive knob as her left hand wanked the base of my cock became too pleasurable to bear. My body locked solid and then began to shudder and shake as an intense and copious orgasm hit me. Normally I'm vocal when I cum but as I didn't want to alert Paul to our little tryst I bit my lower lip. My big thick cock throbbed like mad as it powerfully blasted spunk into Casey's mouth. Her dreamy hazel eyes bulged wide with surprise not only at the power of my orgasm but its copious volume too. The first ten long jets of thick cum blasted into her mouth and I felt it surround my knob. The last two jets splattered on his cute schoolgirl face as her mouth was already filled to the max by my creamy cum. When my orgasm ended I watched Casey swill and savour my spunk around her mouth as if she was tasting the finest wine, but unlike a sommelier she swallowed rather than spat. Casey then pushed the two ropes of my cum from her face into her mouth. It was obvious she was as much of a jizz junkie as I was. Casey then climbed up my gym and sports toned body with her talented tongue leading the way. It flicked up the central cleft of my washboard abs before making its way over my shaved smooth sculpted chest to my left nipple which she licked, nibbled and gently chewed with an expression of sexual mischief on her otherwise angelically innocent girlish face. Casey then dished out the same treatment to my right nipple before she began to passionately kiss me despite my face, lips and tongue being covered in her girl cum which made me wonder if she maybe bi-sexual and liked to muff munch her mates. Even though I had just cum there was something about Casey's sweet innocent virginal appearances and petite yet sports toned teen body that brought out the sexual animal in me and I just had to fuck her senseless then and there even if her older brother was asleep next door. Still kissing I rolled Casey onto her back and thrust my really thick 10 inch cock forward. Her dreamy hazel eyes bulged wide when my prominent ridged bulbous knob popped into the tight O of her steamy hot, soaking wet and velvety soft schoolgirl sex. The hot wet walls of her tight teen twat caressed my swollen sensitive knob as her fleshy labia and tight O of her pussy wanked the thick shaft of my throbbing cock. Her dreamy hazel eyes bulged even wider and she muffled a moan of discomfort when my bulbous knob lodged into the even tighter entrance to her cervix. Despite the slut that Casey was her well used teenage pussy was still very tight. It felt like I had my big thick cock in a soft hot wet tight vice. For a brief while I held my 6 inch by 10 inch cock buried ball deep in Casey's hot wet tight schoolgirl sex to savour the pleasure of it. "Oh my, your cock is so big." Casey moaned in half pleasure and half discomfort at having parts of her pussy tickled that had never been reached before. "What's the biggest cock you've had so far?" I asked keeping my big thick cock buried ball deep in her hot wet pussy as I gyrated my hips with my bulbous knob working the even tighter entrance to her cervix. "My boyfriend and my piano teacher both have 8.5 inch cocks." She panted as she tried to adjust to the size of my big thick cock. "Does your boyfriend know you sleep around?" I asked as I started to fuck Casey. "No he thinks I'm his alone." Casey said with a mischievous smile on her stunningly cute innocent face. "How old is he?" I asked as I started to build up a steady rhythm of thrusting my really thick 10 inch cock into her. "He's an 18 year old prefect in the sixth form." She panted when my bulbous knob lodged into the entrance to her cervix again. "Does he fuck you in school?" I asked getting turned on by finding out about her promiscuous and precocious sex life let alone from the pleasure of fucking her. "Yes in the sixth form toilets at lunch time." Casey replied with the mischievous smile on her cute face growing even wider. Casey so reminded me of myself when I was her age, locked in a school toilet cubical sexually servicing an older boy. "I bet you like feeling his cum leak out of you in class afterwards." I said trying to take Casey's mind of the discomfort of being fucked by my big thick cock and remising about how I had felt in class after a lunch time fuck up the arse. "Yes especially as I don't put my panties back on." She replied with such a naughty smile that was at polar opposites to her sweet innocent virginal appearance. "Mmm kinky. I bet the smell of your fucked and seeded sex has all the boys sat around you hard and the girls jealous." I said getting turned on by finding out just what a cock loving slut she was. "Yes." Casey proudly confessed. For the first few minutes Casey really struggled with the very thick meaty girth and long length of my 10 inch cock. She would whimper and her cute face winced every time my bulbous knob lodged into the tight entrance to her cervix which had never been stimulated before. With her petite frame compared to my 6 foot height and 10 inch cock meant her internal organs must have been rearranged to accommodate me. Fair play to her though despite the fact she was in obvious discomfort she didn't ask me to stop. It felt so good fucking Casey it would have been really hard to stop but I would have done if she had asked. Maybe she felt she had no choice as it had been her decision to sleep with me in the first place. But I suspected the real reason was she was a cock loving slut who views taking a big cock like a scout earning a merit badge. To help take her mind of the discomfort of having her tight teenage pussy stretched to the max and penetrated deeper than any cock had reached before I asked her about her piano teacher. It turns out he was a right pervert, married with a teenage son and daughter. He would get Casey to dress up in his daughter's or Son's clothes and then fuck her in their respective beds. When it came to his son's room he would get Casey to tie up her hair and hide it beneath a baseball cap and bandage her tits flat and fuck her up the arse as she wore his son's clothes or get her to suck him off. That kind of turned me on the thought of watching a 41 year old man fucking a tom boy girl up the arse imagining he was doing his 16 year old son. By now Casey's whimpers were less frequent and her winces more subtle. Sensing she was adjusting to the eye watering thickness and impressive length of my fat 10 inch cock I started gradually fucking her faster and harder. Any moment I expected to awake and find it was all a wet dream. There I was a 23 year old gym and sports toned man fucking a sweet innocent looking but slutty 16 year old schoolgirl with her older brother, who was a good mate of mine, asleep next door. My eyes drank in the sweet innocent virginal looking beauty of her cute girlish face with only her dreamy hazel eyes hinting at the sex mad slut beneath. My nose drank in the heady erotic aroma of man on teen girl sex, the mix of man sweat and pheromones mingling with that of a schoolgirl and her soaking wet sex. Her firm pert 32B breasts with bullet hard nipples jiggled against my smooth sculpted chest as I fucked her. Our pubic bones ground together and our pubes locked like Velcro. Her fleshy labia and tight O of her pussy was wanking the thick throbbing shaft of my 10 inch cock as I thrust it into her with increasing vigour and force. The velvety soft walls of her steaming hot, soaking wet schoolgirl sex caressed and stimulated my swollen sensitive knob before tightly clamping down on it when it forced its way into the entrance to her cervix. The fact Casey was a stunningly beautiful and incredibly cute 16 year old girl was erotic enough but the fact she was a mate's younger sister gave it a kinky edge. After about 10 minutes it seemed Casey had adjusted to the size of my big thick cock. Her whimpers of discomfort were now purrs of deeply penetrated pleasure. My cock was a good inch and a half longer than her two previous biggest cocks but also a dam sight thicker. Her sweet innocent looking face was no longer wincing but had a slutty fuck me expression at odds to its virginal appearance. Her dreamy hazel eyes burned with lust and sexual hunger that my blue eyes returned in equal measure. We alternated between passionately kissing and complimenting each other. Casey told me that the moment she saw me she wanted sex with me and I told her likewise but I never expected it to happen and certainly not by being seduced by her coming into my bedroom unbidden and sucking my cock while I was asleep. Casey told me she loved my deeply tanned all over rugby and gym buff body while I complimented her on her stunningly cute beauty and fit little teen body. She told me how good my really big thick cock was making her tight teenage twat feel and I told her how good it was making my manhood feel. Now that I knew Casey could take my big thick cock I decide to see just what she could handle. Without warning I launched into a fast furiously hard fuck. Normally when I fuck a girl I hold back and I am gentler than when fucking a guy's arse but Casey's sweet innocent virginal schoolgirl appearance brought out the sexual animal in me and I fucked her at full speed. Her dreamy hazel eyes bulged wide with stunned surprise and her mouth dropped open. A domineering thrill coursed through me from being a 23 year old man towering above a petite 16 year schoolgirl who I was fucking as if trying to break her. Whimpers and winces of discomfort returned to her cute face from the brutal battering the entrance to her cervix was taking from my big bulbous knob. The headboard of the bed was repeatedly banging against the wall dividing the guest room we were in and her older brother's bedroom. At any moment I expected Paul to burst in and beat the shit out of me before throwing me out naked into a freezing winter's night a hundred miles from my home. Despite that real possibility it was a well worth risk to have the opportunity to fuck such a dam cute sexy schoolgirl. It had been over a year since I last fucked a 16 year old girl. She was a tom boy skater chic who could hold her own against any boy in terms of skateboarding tricks or arm wrestles. But when she went into the bushes you knew she wanted to be fucked and she refused no-one. Depending on how many had been in before you, you would find her sprawled naked on a discarded gym mat with a puddle of cum between her legs. She loved drinking cum and liked being fucked up the arse as much as her pussy and as she was such a tom boy I wondered if she had gender issues being a gay boy trapped in a girl's body. Anyway I digressed so back to the unbelievably cute, dam sexy seductive Lolita beneath me. Despite the harshness and obvious discomfort my brutally hard fucking was giving her she didn't ask me to stop. My really thick 10 inch cock was alive with intense pleasure. Casey's fleshy labia and tight O of her pussy was wanking the long thick throbbing shaft of my cock as I rapidly and repeatedly slammed it in and out of her soaking wet schoolgirl sex. The velvety soft, hot wet walls of her pussy stimulated my swollen sensitive knob as if giving it mild electric shocks. An explosion of pleasure coursed down my cock every time my big bulbous knob slammed into the even tighter confines of the entrance to her cervix. Her firm pert 32B breasts and bullet hard nipples jiggled against my muscular chest. There was no doubt that Paul knew I was fucking the hell out of his little sister but he didn't intervene. He knew what a slutty sexual minx his younger sister was and he was well accustomed to her seducing his mates. Besides he was just as much of a tart pulling a different girl or woman every time we went out not to mention he screwed Casey mates. Realising I was safe I fucked Casey still harder. She started saying "oh" in increasing volume and pitch every time my bulbous knob slammed into the entrance to her cervix. This went on for about five minutes before her "oh's" turned into "fuck's." Then her lithe young body locked solid and her hazel eyes grew saucer wide. Casey then began shuddering as if being electrocuted as an intense orgasm hit her. Her tight teenage twat spasmed uncontrollably around my pile driving penis as she gushed girl cum on it that leaked out and soaked my balls and the bed sheet. Casey screamed with sexual ecstasy and release as an intense orgasm coursed through her fit young body. Her stunningly beautiful, innocently cute young face looked even sexier in the throes of orgasm. Her saucer wide hazel eyes had an orgasmic glazed look and her cute face had an expression of part stunned surprised and part sexual ecstasy. Feeling her soaking wet, steamy hot orgasming pussy spasming around my big thick cock felt out of this world. Despite that intense pleasure I was still a long way off from my own orgasm. Poor little Casey had to endure another half hour of rough hard fucking before I was ready to cum. By then Casey had become well accustomed not only to my harsh vigorous fucking style but also the thick meaty girth and impressive length of my big cock. Check out the porn stars Steven Prior and Devin Moss to get an idea of the thick meaty monster I was using to fuck my mate's younger, only just legal, sister with. Her well used but still very tight teenage pussy had never been so abused before but there was now no pain only pure hard fucked intense pleasure the likes of which she had never experienced before. Despite the sex mad slut she was, no-one had fucked her as hard as I did or penetrated her pussy as deep as I had. Having a hot, hard thick throbbing 10 inch cock harshly pounding her tight teenage twat for so long proved too much pleasure and she succumbed to a second intense orgasm. Her lithe young sports toned body shuddered from the intensity of her orgasm. Her steamy hot, wet pussy gushed schoolgirl cum onto my pounding cock. Feeling that warm watery rush coupled with her tight little cunt spasming uncontrollably around my thrusting manhood set me off. My bulbous knob slammed into the even tighter confines of the entrance to her cervix proved the final trigger. My cock head swelled stretching the entrance to her cervix still wider as it powerfully blasted a long thick bolt of cum deeper into her than any had reached before. As her orgasm began to fade I fucked her with short deep hard thrusts as I pumped her pussy full of cum. 12 long thick jets of cum were squirted deep into her soaking wet schoolgirl sex. Waves of intense sexual pleasure coursed through me as I bred my mate's barely legal younger sister. As I drained the copious contents of my highly productive balls into Casey I realised it was a mistake. Not because she'd only just turned 16 or that she was a good mate's little sister, who I was fucking in their parental home, but because I was becoming infatuated with this seemingly sweet innocent virginal yet slutty sex mad schoolgirl seven years my junior. My stay was to last but a week and I knew when I returned to my home for Christmas, despite the festive cheer, I would be pinning for Casey's company and the feel of her fit little body beneath mine with my big cock stuck in her steamy hot, wet and tight teenage pussy. When my orgasm ended I collapsed on top of Casey in a sweaty heap with my eye wateringly thick 10 inch cock buried ball deep in Casey's pussy that was full of girl and guy cum. "Wow no-one has ever made me cum twice from being fucked." Casey said in a dreamy voice on the tail end of her orgasmic high. "Sorry if I was too rough, you are just so sexy I lost it." I said as post orgasm guilt hit me. It had been obvious at stages Casey wasn't enjoying it but I carried on regardless. But I wasn't some selfish heterosexual fucker but a bi-sexual who had often been on the receiving end of a long hard fuck and had empathy with Casey. Sure at times it was painful but in the end it was out of this world pleasure that made it well worth it. "Yeah I'm going to have a sore pussy but wow they honestly were the best three orgasms I've ever had." Casey said dreamily looking into my face. "Hopefully not too sore to fuck you tomorrow." I said as I pulled my cock from her hot wet cum filled pussy. "If it is you can always do me up the arse like my piano teacher." She mischievous said with a cheeky grin on her cute face. That thought was such a turn on I almost did it then and there but after prolonged and vigorous sex and intense orgasm coupled with the long day of travelling had drained me. We spooned together with my deflating sex slimed cock in the crack of her very firm, hockey toned arse with my left hand gently groping and massaging her pert perky left breast and tweaking her bullet hard nipple. As we drifted off to sleep we talked about each other's sex life. Casey's sexual education had come from her older brother but not incestuously so. When Casey was 11 she watched, from her bedroom window at night, Paul stood against his car as a girl sucked him off. Immediately she wanted to be that girl, not that she had any plans on her brother. Casey and Paul knew each other were good looking but that was as far as it went. Neither wanted to sleep with the other but both agreed if they weren't siblings they would have. Instead it was the yearning for the feeling of a hot hard throbbing cock in her mouth Casey craved rather than it being specifically her brother's. Then on another night she watched her older brother fuck a different girl on the bonnet of his car. Just has her mouth had yearned for a hot hard cock in it when she saw her older brother being sucked off her virgin pussy yearned for cock when she saw Paul fucking a girl. A couple of months later Casey put the sexual knowledge she had gleaned from watching her older brother being sucked off and fucking another girl to good use when she seduced a 14 year old virgin boy on holiday. Her 18 year old boyfriend was a naive, geeky straight A student but with a cute face, despite the glasses and a sexy lean sinewy cross country runner's body and impressive 8.5 inch cock. Due to his geeky appearance and painful shyness he was still a virgin at 18. However he was the kind of geek that if you took off the glasses and stripped him naked turned into a sexual butterfly, it was his shyness that had held him back for so long. How could a sex mad slutty 15 year old schoolgirl meet a wallflower shy 18 year old virgin sixth form prefect? By the latter finding the former sucking off a 15 year old boy off in the boys' toilet. In order to stop him reporting them to the head teacher Casey offered the prefect a blow job too. Casey was impressed by the size of his cock, the amount of cum he produced and could see beneath his geeky exterior. Besides he became besotted with Casey and showered her with gifts blissfully unaware of the slut she was. He thought Casey was his alone despite the fact she was regularly being fucked by her piano teacher for free lessons, continuing her lunchtime sexual trysts with schoolboys but relocated to the girls' toilet and now in my bed with my cum deeply planted in her pussy. Casey was definitely a female version of me when I was her age. As for me I kept the gay and bi-sexual side of me varied sex life out of the conversation just mentioning the actual straight sex I'd had as well as inventing some more to give her an idea of the slut I was. In due course I would sound her out on her sexuality but I didn't want to ruin possible further sex by confessing me bi- sexuality too early. It was a wise decision as although Casey had no qualms about kissing me after she had cum on my face or I licked her out she was 100% straight. The after sex need to flush out our systems hit us both so we went to the toilet together. Afterwards I expected Casey to return to her bed but instead she climbed into mine. Sexually slatted and with empty bladders sleep took hold of us with me spooned behind her. The following morning I was woken with a blow job. Like the night before I groggily came awake realising a hot wet sucking mouth was working my hard cock. "Morning sleepy head." Casey said with a cheeky smile on her stunningly cute face. "Come here you horny little minx." I replied. Casey kissed her way up my six pack stomach and over my sculpted chest to kiss me. We had a passionate snog as I groped her firm pert petite arse. Her sex was already wet, aroused and pressed against my hard throbbing cock. "How's your pussy?" "Sore" "Too sore to fuck?" I asked. "I have a piano lesson today so if you fuck me again I might be too sore for him." "OK. After your lesson go see your boyfriend so I can have sloppy thirds." I suggested. "Mmm kinky, I've never done them both on the same day before." Casey said with a mischievous grin on her cute face. "It looks like it's going to be your arse then." I said as I gave her pert bum a playful slap. "I don't know about that. If my pussy is this sore my arse will hurt." Casey said with worry. "Don't worry I won't be as vigorous as last night. I'll wear a condom so I can cum in your mouth afterwards." I said as I used the middle finger of my right hand to tickle her arsehole which started to quiver. It took Casey a couple of minutes to come around to the idea but she did. Casey knelt up so that her pert shapely arse was stuck up in the air with her right cheek and shoulders down on the bed. It was a very erotic sight. There were the round firm pert globes of her two tone arse. The outer parts were lightly tanned with the inner bits a pale triangle of flesh that would be hidden by her skimpy bikini bottoms whenever she sunbathed. Her pinkish brown wrinkly pucker looked small and tight. Beneath that were the fleshy pink lips of her aroused schoolgirl snatch. It looked a tasty and erotic sight so I dragged my tongue up between her wet fleshy labia and over her arsehole. Then I started lapping away at Casey's arsehole. "Oh wow no-one has ever done that before, even when my piano teacher fucks my arse." Casey said in a voice that seemed half in disgust and half in pleasure. "It's called rimming." I said taking a brief break before resuming. Casey didn't ask me to stop so I carried on. My licks became shorter as I homed in on her quivering arsehole. Casey might have been slightly disgust at having her shitter licked but that soon evaporated when she realised how good it felt. Then I started stabbing my tongue in and out of her arse like a small dick, trying to worm it in as deep as I could. To finish off I sucked and chewed it which had Casey purring with pleasure. When I thought Casey was ready I rolled a condom onto my huge cock and generously lubed it up. Then I finger fucked some lube into Casey's tight little arse. Taking my time I started with the middle finger of my right hand and as her arse started to loosen I added more and more digits until I was using all five down to the base knuckles. When I thought Casey was as ready as she'll ever be I got ready to mount her. After shuffling forward so that I was knelt behind Casey I aimed my fat 10 inch deeply tanned cock at her arse. Seeing my big bulbous condom covered knob next to Casey's small pinkish brown knob it looked like there was no way it was going to go it. "Oh fuck that stings." Casey squealed followed by several pants of pain. Casey's upper body bolted upright so that she was in the doggy position. Her hands clenched the bed sheet so tightly her knuckles went white. To give Casey time to get over the pain of having her arse breached by such a fat cock I held still. For me it had been great. Her really tight sphincter slid down the increasing tapper of my bulbous knob before popping past its prominent ridge to tightly clamp around my fat cock shaft in a vice like grip. Even though I was wearing a condom the hotness of Casey arse soaked into my sensitive knob. When Casey's upper body crashed back down onto the bed I started slowly forcing more of my fat 10 inch cock into her tight little arse. Casey groaned in discomfort and clenched the bed sheet but she didn't ask me to pull out. When I felt my bulbous knob touch the entrance to Casey's colon I stopped. Casey had taken about two thirds of my 10 inch cock so I held still to give Casey time to adjust to having her arse stuffed so full of fat cock. It gave me time to savour the hot tightness of her overstretched arse. When I felt Casey's arse loosen a bit I started to fuck her with slow gentle thrusts always stopping when my knob touched the entrance to her colon. Casey whimpered and moaned in discomfort but she didn't ask me to stop. To help take her mind off the pain in her arse I frigged her bullet hard clit with the middle finger of my left hand. Her whimpers of discomfort start to be interspersed with purrs of pleasure. A combination of her arse starting to adjust to the thick meaty girth of my cock coupled with me frigging her clit meant I could gradually start to pick up the pace. Normally it takes me ages to cum but I knew Casey wouldn't be able to take a long anal fuck so I willed myself to reach orgasm earlier than I would have otherwise. Not that I was lacking physical stimuli despite wearing a condom. The heat and tightness of Casey's arse soaked into my fat throbbing cock through the condom. As I thrust my big thick cock back and forth Casey's tight little sphincter gave it a great wank job. There was also the erotic sight of my gaze flitting between watching my tanned fat cock slowly thrusting between her pert two tone buttocks to looking up at her cute innocent looking girlish face. Several minutes into the fuck Casey started getting used to it. She no longer needed to grip the bed sheet so she started to finger fuck her soaking wet sex and I frigged her bullet hard clit. Moans of sexual pleasure began overriding her groans of discomfort. Her petite lithe young body began building sexual tension. About fifteen minutes into the fuck the familiar pleasure of fingering herself as a young man fucked her arse and rubbed her clit got to Casey. "Oh fuck I'm going to cum." Casey squeaked before the sound of watery girl cum splattering on the bed sheet. Her lithe young body violently shuddered from the intensity of her orgasm. With each spam in her soaking wet sex Casey squealed with sexual ecstasy. When Casey's orgasm ended I pulled my cock from her arse. Her once pinkish brown small pucker was now red, swollen and gapping open. As Casey was drained from the intensity of her orgasm and lost on an orgasmic high it was easy for me to flip her body over. Then I pulled off my condom and straddled Casey's chest. Her stunningly cute, sweet innocent looking face was flushed red from orgasm. With an all too familiar grip I began wanking my cock with my left hand. My tanned foreskin frop-fropped over my big bulbous knob. My familiar tight grip made my big thick cock throb with pleasure. On top of that there was the erotic sight of Casey's sexy face. After a couple of minutes I was ready to blow. "Open wide." I said. Casey opened her mouth ready to accept my load. "Here it comes." "Cum in my mouth." Casey said with an open mouth. The first large bolt of cum exploded out of my cock and scored a direct hit in Casey's open mouth. Then eleven more large ropes of thick white cum exploded out of my cock. Most of it went into Casey's open mouth but some splattered on her cute face. My moans of sexual ecstasy and release mingled Casey's purrs of pleasure at the taste of my cum. When my orgasm ended Casey closed her cum laden mouth and swilled and savoured my spunk before swallowing it. Then I used my tongue to steer my cum from Casey's face into her mouth. Then with us both sexually slatted I rolled over to lay beside Casey. "So are you going to do both your piano teacher and boyfriend?" I asked. "Yeah it sounds kinky." Casey said with a cheeky smile on her cute face. We then went and showered separately before going down for breakfast. Paul was already there and seemed to have no problem that I'd spent the night fucking his younger sister. Paul wanted in on the action and asked Casey to arrange a sleep over with his favourite of his sister's mates who was a busty red head. Casey then went off to her piano lesson whilst Paul and I went to the gym. I hope this one got you off and you're sat there splattered in cum.
