People generally assume that if you’re experiencing feelings of lust for someone other than your partner that you must be either a bad person or someone in an unhappy relationship. However, what people don’t always understand is that whilst you may love someone, this does not mean that they will necessarily fulfil each and every aspect of your desires and longings, which can leave your sexual needs unsatisfied. I suppose you could say that this depicts my situation, though it isn’t really my boyfriend’s fault – as a young, lusty 21-year-old with double D breasts and a love for dirty fantasies and kinky fucking, you could very well say that I am almost insatiable. It barely seems fair to say that my poor boyfriend can’t keep up with me, though I had never considered cheating on him – that is, until I met Robert…

One thing you ought to know about me is that, in a sense, my life is a double act. By day I am the admirable student: academic, articulate and an able member of our prestigious church choir. But at night, on the other hand, I become a filthy sex kitten, loving nothing more than a night of hot, sweaty grinding on the dance floor pressed up against a raging hard-on in a club, and what better way to follow this than several hours of rampant fucking? Whilst Tom, the guy I live with, loves me and does his best to satisfy me, his idea of a fun night has recently been a DVD and couple of cans on the sofa – needless to say, our sex life has dwindled over the past months. I have no shame in admitting that I now spend several nights of the week satisfying myself, stroking my moist pussy into a frenzy whilst I fantasise over indiscriminate hard dicks and big, juicy tits with erect nipples. These adulterous thoughts were mostly random at first, although it did not take long until I found someone real to fantasise over, and someone from a most surprising source, too!

Everyone at church was disappointed to hear of the retirement of our organist and choirmaster, as he had been with us for so long and was endowed with such exceptional talent that I, along with everyone else, thought that he would be irreplaceable. When his replacement Robert arrived, I admit that he did little to change my preconceptions; he was young (around 27, which is practically infantile in comparison to his elderly predecessor), though rather than appealing to me, his youth just made me scorn his inexperience. This, along with his glasses, sandy hair and slightly awkward mannerisms utterly disappointed me, as I confess that it had entered my mind that our new master could potentially have been a sexy, hot guy (just to look at, of course!). I supposed that he seemed a good enough teacher, and I admit that I was quite surprised at how this slightly nerdy young man could command the respect of the choir so easily, but he was still a bit of a drip and, in my naïve mind, far beneath my notice. How wrong I was!

We usually perform twice on a Sunday and once on a Thursday evening; I usually commit myself whole-heartedly to my singing, as despite my lustful longings I am passionate about my music, although I do sometimes wryly wonder how my peers would react if they knew about my ‘other side’. In fact, I often go out with friends after Thursday evensong, meaning that underneath my traditional and almost saintly robes I am wearing the most outrageously sparse outfits, though as they are so well concealed I usually figure it is safe to do so. It was on one of these Thursday evenings that Robert approached me before the service started.

‘Hello Kate,’ he said, in his soft yet well spoken voice. ‘I was wondering if you would mind page turning for me at the end of the service as my assistant can’t make it tonight.’

I was pleased, as I secretly rather liked going up into the organ loft and surveying the soft shadows of the beautiful building from up high.

‘Yeah sure, that’s fine with me,’ I replied. ‘I’ll come straight up after we finish.’

Therefore, after the service I removed my flowing robes and made my way over to the organ loft; I ought to have registered that whilst he may be a church organist, he was still a man, and my heaving bosoms and tight ass in size 8 jeans may not have escaped his attention, but I just sauntered up there without a second thought, sex being, unusually, the one thing not on my mind. He had already started the piece – Bach, fast paced, fervently passionate, with deep notes that throbbed through my entire frame – and his long, sensual fingers caressed the keys with such a firm yet gentle precision that they moved like liquid. So lingering and throbbing were the notes that the vibrations seemed to transfer themselves straight from the long pipes into my body, sending tremors from my exposed neck and chest down through my clit and into my curling toes. Both flushed and slightly taken aback by the sensation, I lifted my eyes to Robert’s face; beads of sweat slid down his forehead into his furrowed brow as he lifted himself from his seat in exhilaration, shaking with the ardour of his performance. He was not the only one to feel excited now; I was surprised to feel my breath shudder with stimulation as I leaned over him to turn the page, noticing as I did so that my luscious breasts, nipples slowly hardening, were just inches from his moistened lips. It was far too soon for my liking that Robert brought the piece to a throbbing climax, pitching his hands at the keys with an unequalled passion and with dramatic flourishes that sent the arousal from my nipples all the way down to my pussy in warm, quivering tendrils. Feeling both surprised and slightly shameful, but with my perception of Robert most favourably altered, I chatted to him in a manner that I hoped did not betray the now considerable wetness of my lacy thong, before saying goodbye and exiting the church door.

After having a few drinks with my girlfriends, during which time I barely spoke, for some reason enjoying myself less than usual, I arrived home to an empty house, smiling coyly at the recollections of what had passed in the church. My heart was still racing from my shock over being so aroused by a man who was, in a sense, my teacher, but all this did was heighten how turned on I had been as I had leaned over him. I savoured this thought as I felt myself tingling with pleasure, then, with a shuddering gasp, flung myself on the bed and ran my fingers over my nipples, which were now standing erect at the mere thought of him. I slid my hand under my bra and caressed them, enjoying the sensation of the soft skin of my breasts underneath. Gently rubbing my hard nipple between thumb and forefinger, I thought of Robert’s sensual fingers and how effortlessly they had commanded the keys whilst wondering what they could do for me. I was so aroused at the thought of him running those hands over me that I felt my pulse quicken, my breath now coming short and fast. Feeling that I had now been teased long enough, I slipped my other hand under the waistband of my jeans and drenched thong, and, with a slight moan of pleasure, began to stimulate my smooth, aching pussy that had longed to be touched all evening. I smiled at the thought that Robert probably just thought I was another good little church girl; he had no idea of the dirty slut I really was. Relishing the notion, I slid my forefinger inside my dripping cunt, whilst slowly circling my clitoris with my thumb until it stood up, firm and poised. Thoroughly enjoying the advantages of an empty house, I fingered myself for all I was worth, beginning to gasp and cry out as I stroked myself faster and faster, my juices covering my fingers more and more until I came all over myself, exultant with guilty pleasure over my very naughty fantasies.

Over the next days I could not rid my head of these thoughts, wrong as they were, because I now knew that what attracted me most to Robert was that he was the forbidden fruit. Unlike the men in bars and clubs who would practically drool at the sight of my lithe, sexy body and luxuriant dark eyes and hair, he was righteous (it even entered my head that he might be a virgin, as it seemed unlikely that his shy manners and unassuming nature would attract a lot of women), and was therefore unlikely to think of me in that way. This thought began to drive me crazy! Some hidden demon within me wanted to throw myself at him, tear off his clothes and fuck him senseless, teaching and him and showing him how intense filthy sex could be. I spent a lot of time idly wondering if he ever masturbated, and if he did, then did he think of me? The idea of him picturing me whilst he touched himself was almost too much, and my cunt would tingle tantalisingly at the thought. I would often find myself pondering over the size of his dick as he was teaching me, speculating whether or not any dirty fantasies resided under that cultured veneer, and if so, what made him hard? I began wearing more revealing outfits to church, offering to page turn for him at each opportunity so that he could get a glimpse of my deep cleavage and a whiff of my seductive perfume every time I bent over him. My skimpy skirts attracted some mutterings from the congregation, but the dirty slut in me just did not care – I was a woman obsessed, and I had to have him…

Although I had initially thought that a man like Robert could never be interested in a girl like me (particularly if he found out how filthy I was), I began to notice a slight, though perceptible, change in his behaviour towards me. I was not sure whether it was just my desire for him that was making me see things that weren’t really there, or whether they were genuine, but I began to notice Robert looking my way more often than was necessary and finding excuses to come over and talk to me after rehearsals. This continued for a few weeks, with my fantasies about him growing increasingly dirty. I constantly thought about straddling him and teasing myself by rubbing his big cock over the entrance to my pussy, enjoying the idea of suddenly thrusting him inside me and hearing his gasps of mingled pleasure and amazement that fucking a kinky girl could feel so damned good. I loved the idea of pressing my breasts around his hard-on, stimulating him and rubbing up and down until he exploded hot, sticky cum all over my chest, destroying any wholesome impressions he had of me. So very dirty were my imaginings that it was with a slight blush that I responded to a question he posed for me one Sunday morning:

‘Ah, Kate, just the person I wanted to see,’ he said, smiling in a way that made me want to melt. ‘We need someone to perform a couple of arias during next month’s programme, and we’d be delighted if you’d accept the offer. It will mean more rehearsing, though- possibly on a one to one basis.’ He looked at me questioningly, with his sandy-haired head slightly to one side.

‘Yes, thank you, I’d love to!’ I replied eagerly. He looked pleased, though a little surprised at my enthusiasm, and began suggesting times to meet for practice. We soon had a date booked in, and our first meeting took place after our weekly evensong service, in the practice room opposite the church.

‘Hello, Kate,’ he said, smiling his warm, reticent smile. ‘Please come through and sit down at the piano.’

I entered the room and did as he had asked, trying to hide my delight when he came and sat down next to me. Sitting side by side on the piano stool it was hard to avoid his touch and I experienced a thrill of pleasure and arousal at the feeling of our thighs brushing together. Although the old wooden room was dimly lit by lamps and the moonlight streamed in through the high, old-fashioned and uncurtained windows, did I see him blush at the motion too? As he began to play for me, singing was the last thing on my mind, I wanted him so fucking much; I had been careful to wear my sluttiest outfit yet: a tight fitted red top that my breasts almost spilled over and a dark black skirt that came above my knees. However, I tried to keep things casual – after all, I had a boyfriend and fucking the church choirmaster would be a new low for me, despite my abundantly kinky sexual conquests. Therefore, when he made a mistake I pointed it out with a fluttering laugh, and stirred my hand across the piano to put it right. However, with a flush of surprise I felt his warm fingers under mine, and realised that he had automatically moved his hand there too. There was a flurry of electricity between us, and as I looked up I caught his eye; the expression on his face was both confused and hopeful, though a rosy glow still seemed to be covering his cheek.

I did not know what to say. I was almost determined to just collect my music and go home when the familiar tingling of my pussy reminded me of all my sexual frustrations, longings, and filthy desires. In that instant I threw caution to the wind and, as if in answer to his questioning look, I placed my free hand on his thigh and slowly and gently began to stroke it up and down. Though his face was still coloured, this appeared to inspire him on, and before I knew it he was kissing me – deep, long, desperate kisses that shook me throughout and sent wisps of pleasure into my every crevice. Whilst our tongues were busy exploring each other’s mouths, our hands eagerly explored the other’s body. As I had so long fantasised, I tore off his neat tie and began unbuttoning his crisp shirt, revelling in the sight of his smooth chest and exposed nipples.

‘I’ve been wanting to do this to you for so long,’ I murmured into his ear, as his hands hovered nervously on the clingy fabric underneath my breasts.

‘To me?’ he said, with a look of surprise. ‘But you’re so young and beautiful and I’m just, Robert…’ he trailed off.

‘Yes, well,’ I answered with a coy smile, never taking my hands off him, ‘there’s a lot about me you don’t know, especially what a dirty girl I can be. You have had sex before, haven’t you?’ For a moment I thought that I had said the wrong thing, as his expectant glow faded and he looked embarrassed.

‘Yes, of course I have. But not for a few years and it was only ever with one girl who was nice, but just...’

‘Boring?’ I ventured. ‘Well that’s certainly not me.’ With that I sat up, pulled off my tight top revealing a sexy, black lace bra and placed his nervous hands on my eager breasts. At this, he let out an uncontrolled moan of pleasure, which turned me on more than anything yet. I now knew that I was going to have him, to teach him, and, most importantly, to dominate this young man out of his sexual naivety. With this thought I reached down to the now palpable bulge in his trousers, which had not escaped my notice, and unzipped them to reveal a raging hard-on, the like of which I had never seen before. Admiring his 9-inch cock that was already beginning to glisten with moisture at the tip, my pussy began to pulsate with pleasure and intensified arousal; right then, Tom and my dwindling sex life could not have seemed further away. My delight must have registered in my face, as it seemed to give him the confidence to begin caressing my breasts, kneading them and slipping his hands under my bra so he could play with my erect nipples whilst breathing warm, loving breath on my neck. As those sumptuous hands that had caressed the organ keys with such fluidity caressed me in the way I had so long desired, I had to fight the temptation to ram myself over his cock right then. However, I wanted to wait and draw him out, so instead I ran my fingers teasingly over the end of his dick to make my attentions firmly known, if not yet carried out; he gasped with delight, so I sat up invitingly and, taking my hands off him for a moment, unhooked my bra and gently guided his head to my tits as he so clearly desired to have some more fun with them, and sure enough, my nipples were soon in his mouth as he sucked busily, his dick growing, if possible, harder underneath my firm grasp. I had now fully removed his shirt and loved the feeling of our semi-naked bodies pressed together.

‘Oh Robert,’ I moaned, ‘I need you to touch me.’

My pussy was dripping from underneath my skirt, so I deftly removed my panties and straddled him, with his head still nuzzled between my breasts whilst I kissed each part of him that I could reach. I secretly relished in the fact that he had not responded to my command; his inexperience only allowed me more room for instruction and dirty talk. Loving the fact that he clearly had no idea what to do next, I whispered in his ear, ‘How would you like to have me naked?’

‘I’d be lying if I said I hadn’t thought about it,’ he replied.

Smiling seductively at him I murmured, ‘I knew you were just a man, Robert Waslin.’

And with that, I deftly removed his trousers and boxers and looked at him expectantly. It was now his turn to smile as he unzipped my skirt and looked down for the first time at my smooth, shaven pussy, engorged with arousal and dripping with sweet juice.

‘Now, Robert, that’s what it looks like when a girl is so hot for you that she’s going to fuck you senseless. But first, you’re going to give me a little treat, ok?’

He murmured his eager assent so I guided his fingers down to my moist, warm clitoris, instantly sighing with long awaited pleasure as I felt them make contact. He appeared to take my uncontrollable noises as a sign of encouragement, as he slowly began to manoeuvre his deft fingers between my legs.

‘Spread them wider,’ he said, in a breathy whisper that made me shudder. His initiative both excited and impressed me, and I obediently spread my legs over the stool so that he could view and touch me at his leisure. His fingers now slid rapidly over my hard clit, that stood as erect as my nipples, and I relished in the intensity of the sensation as he rubbed me back and forth. I let out an involuntary whimper of surprised gratification as I felt him enter two fingers into my sticky cunt; my fervent response was to gyrate my hips so that he slid in and out of me, finger fucking me like the dirty slut I was. Each time he slid in and out of my lubricated slit he teasingly made contact with my hardened clitoris, excitement and passion clearly coursing through him as he continuously played with my breasts with his free hand. As I felt his fingers collide again and again with my sensitive pussy wall, I could feel my entire body beginning to give in to shuddering spasms of sexual pleasure: if I didn’t stop him I was going to cum, and it was far too soon for my liking.

With a remorseful gasp I slid myself off his fingers, telling him that it was now his turn to revel in some sexual indulgence. This time, I took control, pushing his sexy, naked body down onto the piano stool, whilst I crouched over his erection. Kissing his neck slowly and seductively, I began to stroke his pulsating cock with my warm palm, enjoying watching his eyes widen with pleasure. I then took his wide shaft and gently but firmly began to pump him up and down, hearing his breath quicken as I did so. I teased him like this for some time, pumping his cock with a tantalisingly slow fluidity whilst he gasped and moaned underneath me. When his moaning began to suggest he could not take much more, I deftly removed myself from his body, now crouching near his feet at the end of the stool. Robert looked at me with frustration, and I could tell what he was thinking: that I was a dirty little cock tease. Well at least now he knew I was no virgin! I had been good to him so far, but if he wanted more, he would have to ask.

Spreading his legs so that my head was positioned alluringly near his groin I said, with my warm breath purposefully straying across his balls and shaft, ‘Now, I know how young men don’t like to be left unsatisfied, but how am I to know what you want? I am just a young girl, after all.’

I’m sure he saw straight through my wicked smile, but the twitching in his rock hard dick seemed to spur him on as he looked at my moist lips perched just inches from his moist and glistening head.

‘Please Kate, go down there,’ he said, a trace of embarrassment still apparent in his voice.

‘Sorry Robert, you’ll have to be a little more specific than that,’ I responded, lightly pressing my breasts against his groin.

He let out an almost indistinguishable sound of frustrated pleasure, so I decided to taunt him just a little more, ever so gently running my tongue over the tip of his engorged cock whilst visibly caressing my own breasts. This appeared to be too much for him.

‘For fuck’s sake, give me head!’ he cried out, now apparently unable to control either his sexual desires or his public school boy manners. ‘I want you, Kate, I want my dick inside your mouth, ok?!’

Delighted with my triumph, I immediately plunged his dick into my moist mouth, feeling my already swollen clit engorge with the naughty feeling of having the choirmaster inside me. As I did so, my own frustrated pleasures came forth in a deep and throbbing moan of delight, which vibrated through his cock so that he gasped and cried out uncontrollably. His dick was so big that I barely thought I could take it all in, but I thrust my greedy lips forward and took him in a deep throated movement that seemed to exhilarate us both. So as not to allow him too much gratification yet, I alternated between deep throating the entire length of his substantial cock and tormenting him with the gentle yet precise flickers of the eager tongue and lips that had sung his fine music. I suddenly realised that Robert’s hands were woven in my hair; no longer submissively enjoying my sucking on his cock, he was holding my head, even beginning to guide me back and forth to make sure that I gave him exactly the blowjob he wanted. Thrilled by the idea that I could be pleasuring him so much, I pressed my hot, wet tongue up against him as he gyrated back and forth into me, moaning with pleasure all the time. I now realised that he was in fact fucking my mouth, and the tip of his prick momentarily pressed against my lips every time he withdrew. Enough was enough. Now, I simply had to have him.

With a last slurp of his delicious cock, I removed my sweet, sticky lips and rose myself to a standing position, allowing Robert to survey my young, curvy body with enjoyment. I turned to the side, with my back pressing against the piano keys, and held out my hand invitingly. He rose obediently and turned to face me, so that his face was inches from mine and I could feel his warm breath on my neck. He urgently kissed the lips that had so recently been wrapped around his prick before allowing his hands to stray to my waist and begin caressing my firm ass. I reached into him and said softly but assertively, ‘You do know I’m going to fuck you now, don’t you, Robert?’

His expression said what his words clearly could not, but I knew that he wanted this just as much, if not more than I did, and perhaps had done so for quite some time.

With that I placed my hands behind me, so that I was leaned against the piano, and allowed him to continue caressing me, delighted when his hands now strayed to my pussy without my guidance. After a few tantalising moments with my clit, his hands, which now dripped with my cum, forced my legs apart and, with a last, lustful look, Robert thrust his dick inside me, sending pulsating spasms of fire right to the ends of my each and every finger. I clenched my pussy around him, feeling his entire length sliding smoothly inside my walls then slamming up against my sensitive spots. It felt so fucking good, but I wanted him to know just how good it could be. I pulled my hips back tentatively, so that the tip of his cock momentarily rested on my clit with a sensation that made me gasp with joy before slamming it deep back in me with a commanding movement. Each time I did this I looked at his long, hard shaft, thrusting it back and forth as Robert emitted his own little cries that mingled with my own aural expelling of pent up longing as I fucked him. I had worried that my tight, young pussy would not take him, but his cock, coated in our mixed cream, glided in and out of me perfectly. Biting down on my lip to control the intensity of my arousal, I glanced up at his face to see his eyes alight with passion and boring into mine, perspiring in a way that set his whole body on fire as it gyrated against me.

‘Oh Kate!’ he gasped, now apparently devoid of embarrassment. ‘Oh fuck! Oh fuck do you feel good! So warm and deep around my cock! Just you keep on fucking me, please don’t stop, whatever you do, you sexy, dirty girl!’

As he pounded me faster and faster, increasing the volume of my cries and sending tremors between us, I grabbed his ass and pulled him ever deeper into me, crying out louder and deeper as he penetrated me in ways that I had never been penetrated before. He was no longer the mild-mannered choirmaster, but a filthy, horny, sexual beast who was just as desperate for an earth-shattering orgasm as I was. We both increased in rhythm, our hands frantically fondling every part of each other that we could find whilst his stiff cock pounded in and out of me over and over again, the piano keys emitting a frenzied chorus of notes as Robert pounded my ass against them. Perhaps fearing that someone may overhear the discordant notes, he withdrew his dick, picked me up in a single movement and lay me down on top of the piano. In an instant he was on top of me, spreading my pussy lips wide before re-entering with a powerful thrusting motion that almost made me sob with pleasure. One hand was lovingly wavering through my hair and on to my neck whilst the other stimulated my clitoris. My response was immediate and I let out a resounding cry of pleasure as I felt my orgasm beginning to build: ‘Oh, Robert! I’m going to cum so hard on your dick!’

‘Then cum with me, you sexy slut!’ he cried, with a resounding shudder that shook him from him trembling lips to his immense, throbbing cock that pulsated so wonderfully within me.

With a mutually momentous gasp of pleasure, we exploded in a simultaneous orgasm that made us shake throughout, his wonderful body pressed against my breasts as I felt his cock releasing jets of hot, sticky cum all up inside my now slack and lubricated pussy. With a final shudder I felt Robert relax inside me, as my own racing heartbeat began to slowly return to normal.

For a few moments we lay there without speaking, both too astounded by what had just happened to verbalize what we were thinking, until he broke the silence.

‘I could lose my job,’ he muttered, his nervous demeanour beginning to return.

I smiled coyly – wonderful as it had been, did he really think I was going to tell anyone?

‘Robert, I have a boyfriend and you have a job. We both have a lot to lose. However, it’s obvious that we both have desires that need fulfilling, so where’s the harm in us lending each other a hand every now and then?’

It was now his turn to smile, before replying, with a newfound poise that impressed me: ‘I can think of nothing more charming. So, on with the arias?’
