At long last, Fiona clicked “Save” on her final statistical analysis report of the current academic year and could finally turn her thoughts towards going home. As a senior member of the department's research team, she very much had the run of the ancient university, and she took advantage of this each summer to escape the madness of the city's annual comedy festival by getting along on with her work in the quiet oasis of her second-floor office.

With the possible exception of the Christmas break, this was very much Fiona's favourite time of year. All the lecturers and students were away until September, allowing her to bask in the solitude afforded her when the few staff who had remained were also absent. A major reason for this being that, for all her prim and proper demeanour, Fiona was at heart a perpetually horny, dirty young pervert: one who enjoyed indulging her various kinks in situations where there was a distinct possibility she might be discovered; often coming to work having “forgotten” to don any underwear before leaving her flat.

On these occasions, Fiona would often complement her commando state by dressing in light, flowing skirts or dresses, where any strong waft of air lifting her hem to reveal her bare bottom or pussy was a very real risk.

Today, however, was one of those special days reserved for when she released an important statistical report, made even more special when it coincided with an occasion like the Festival, where she had an excuse to spend the entire day dressed in her old school uniform—full commando underneath, of course, with the added bonus of the summer heat lending her a perfect excuse to leave her unflattering blazer at home.

As it was, looking at her reflection in the mirror above the basin as she freshened herself up in the faculty restroom before leaving, Fiona saw how her thin school blouse was leaving very little to the imagination. Whilst her breasts her still modestly pert and succulent, they had certainly matured since her schooldays, and now pressed tightly against the lightweight garment, her coral-tipped nipples clearly visible to anyone brave enough to look carefully at them.

“Hmmmm... not too shoddy, even if I say so myself,” Fiona mused as she admired the sexy young lady looking back at her in the mirror. She felt a tingle of arousal teasing from between her legs and watched her reflection's nipples harden beneath her now immodestly tight blouse.

Ordinarily, when she felt herself becoming aroused like this, Fiona would quietly make her way home to take care of it, or seek out a fellow lesbian in a bar and find a secluded corner somewhere where her new lover could hopefully help ameliorate her parlous state. But on this occasion she held her breath momentarily, to ensure there were no sounds of anyone else nearby, then wet her fingers under the cold tap before touching them to the tips of her breasts through the thin cotton.

Fiona watched in sensuous delight as the thin cotton acted like blotting paper, soaking up the water and turning those areas of her blouse tantalisingly translucent. As she watched, her nipples appeared to blot up this cool water too, burgeoning before her eyes into achingly hard erection, which she started plucking and cajoling into vibrant, succulent cherry stones.

Then, leaving one hand to continue fondling her breasts, Fiona grabbed the hem of her school skirt and, with well-practiced efficiency, promptly tucked it straight into the waistband. Her shaven pussy was now laid bare, and Fiona could actually see its slit glistening back from her reflection. Going commando in public ordinarily made her moist, but being able to spend the whole day in school uniform, sans any under-garments at all, seemed to make her bare-arsed pussy even doubly so.

With her cunt pulsing in arousal, a provocative thought then entered the horny young lesbian's mind. Her heart pounding with excitement, she hurriedly unzipped her skirt entirely and let it slide down her long legs to puddle around her feet, sending a swirl of air kissing delightfully through her legs.

Having always been slender and long-legged, especially so during her school days, Fiona had grown even taller since gaining adulthood, and her school blouse now covered only the upper half of her abdomen. From its hem to the tops of her white knee-length socks, Fiona was now completely and excitingly naked and cleanly shaved.

A rush of lust rushed through her when she considered this: she was in a semi-public place where she might, theoretically at least, be discovered at any moment.

Her pussy churned, crying out to be touched, and she could deny it no longer. Watching herself in the mirror, Fiona smoothed her hand down over her pubis and sent a probing finger deep into her glossy slit.

Unable to prevent herself, she ejaculated a bright, exultant gasp, which echoed around the restroom and, presumably, through to the corridor outside. Fiona froze, her breath caught, her senses straining for any indication she had been overheard.

She lasted a full five seconds before giving out under the pressure of having a stationary hand in her cunt. Expelling a hearty sigh of exultant satisfaction, the oversexed beauty continued on from where she had left off, earnestly scrubbing at her sopping wet quim like the sluttish whore she often fantasised herself to be.

It struck Fiona then that university security should be doing their rounds around now, which sent a frisson of excitement through her vulnerably exposed young body. With a sense of exquisite urgency, she thrust a hand up under her school blouse and onto her firm-fleshed breast, trapping its rubbery nipple tightly in the crook of two fingers as she began massaging and palpating the supple, sensitive mound.

Between her legs, Fiona's fingers took on a palpable sense of urgency. As she massaged her oily slit, she began bumping the heel of her hand regularly and enthusiastically onto her tumescent clitoris. Fireworks began erupting in Fiona's libido: at first modestly, but speedily building inside her, promising to ignite very soon with explosive power.

Then a curious thought struck Fiona, to try using the firm flesh of her palm heel to crush and grind her plump little clitoris as she bumped it, using the same technique as when she was kneading her homemade bread.

The intensity of sensation was immediate, a heady cocktail of pain and profound pleasure, causing Fiona's head to swim and a strangled yelp to escape her lips. She squeezed and twisted her nipple as she crushed down hard on her clit again, and sent two fingers spearing deep inside her bubbling-wet cunt, right up to her pristine though much-fingered maidenhead.

It was almost enough. She could sense her orgasm like a sentient being hovering closely nearby. Waiting for one tiny spark to finally ignite its fireworks.

In her mind's eye, Fiona saw the restroom door swing open and a security guard enter. It is old David, a man a few years past his official retirement age, but a man that Fiona had secretly been fantasising about for longer than she cared to remember.

“My my, what do we have here, then?” said David in his rounded Glaswegian brogue. “No, don't stop; the question was rhetorical. I know exactly what you were doing, you horny little cunt, having a sly little wank before you fuck off home.”

There was a momentary pause before he continued. “Mind if I join you? Not that you have much say in the matter.”

Fiona was mortified. Here she was, standing with her breasts and pussy completely on display, caught with her hand not only in the proverbial cookie jar, but determinedly continuing to finger-fuck it. She desperately wanted to stop masturbating, but David had ordered her to continue. Even worse, he was now unzipping his fly and walking purposely towards her. In seconds he was standing right before her.

Having been a card-carrying lesbian ever since she had first kissed another girl in school all those years before, Fiona had never seen a penis before, let alone a grey-haired old man's. Small wonder, then, that she couldn't take her eyes off David's when it lurched out through his open fly, already ominously half-erect.

Seconds later, the unwelcome security guard had unbuckled his belt and his dark trousers dropped to the floor. A pair of plain grey boxer shorts swiftly followed, and as David hurriedly divested himself of his uniform jacket, Fiona found herself confronted with a candidly unrestricted view of the old man's cock and balls. Surprisingly, perhaps, it was larger than she would have expected, maybe even bigger than a strap-on that a girlfriend had tried to force into her a few months before. Except that David's intimidatingly hefty cock was made of flesh, not latex—and a little too much of that, she thought, though how was she to know that the veiny sleeve of skin she was looking at would tighten around the shaft when it became fully erect? Similarly, the wrinkled, turkey-wattle scrotum hanging loosely between his legs would tighten up considerably when showtime arrived. How was any dyed-in-the-wool lesbian supposed to know that?

Without realising, Fiona must have been so transfixed by the sight that she had paused in her masturbation, causing David to snarl at her threateningly. “I told you not to stop,” he said, dumping his jacket on the floor and unclipping his work tie before tugging at the buttons on his shirt. “But as you have, let me get a good look at you before you start wanking again. I watch you walking past me every day, and I've often wondered what those perky little tits of yours actually look like. And while you're at it, sit right up on that sink unit, would you? Spread your legs, so I can get a good look at your juicy young cunt as well.

“Fuck me, that hand of yours is soaking wet, girl, you must be dripping down there! Put it in your mouth and lick it clean. Do it slowly, like you're tasting one of your girlfriends. That's it, slow and sexy, one finger at a time, like you're sucking a cock—or a dildo, I should say.

“And yes, I know you're a lesbian, we all do. Is that why you shave yourself down there, so you're all pretty and clean for when your girlfriends queue up to tongue-fuck your drooling wet cunt?”

But, as disconcerted by David's presence as she was, Fiona was embarrassed to realise her body was responding to his foul, provocative language: her breasts ached to be groped and fondled again: and yes, she did, indeed, have a drooling wet cunt, as he'd said. Sitting up on the sink as ordered, she could feel its juices leaking down over her anus and through the crack of her bottom. She felt so wanton, knowing that David could see all this and, though she hated herself for doing so, Fiona spread her thighs even wider than he had requested, as if she were offering herself to this toilet-mouthed old pervert voluntarily.

Without even pausing as he thumbed open his shirt buttons, David shuffled himself closer still, until the glossy, angry-purple tip of his penis was barely two hands' breadths away from her unprotected opening. She watched, intimidated but fascinated nonetheless, as David's penis inflated even further before her very eyes, stretching out now into full erection. The loose collar of prepuce that had been concealing the bulbous end of David's penis tightened and peeled back, revealing its shining, balloon-taut glans. And as she watched, a small hole at its tip pouted open and sent down a glistening bead of pre-cum, which just hung there, as if suspended on a silver string.

The reason for this last surge of arousal became evident when Fiona noticed the old security guard's nostrils flare open. Fiona was mortified: was he actually filling his lungs with her sexual odour?

He was! The disgusting old pervert thumbed open his uniform shirt and shrugged it off his shoulders, sending it to the floor. He was now naked from the bald spot in his thinning grey hair right down to his ankles.

“Ah,” he said. “The delicious aroma of an aroused young cunt, I love when it fills a room with its scent. And I could smell yours, my dear, halfway down the corridor.”

He then sniffed the air, as if he were a connoisseur, adding, “Ah, do I detect a hint of virgin in your musk, or do you just pretend to be a lesbian so the boys try even harder to get into your knickers?”

Fiona's face flushed at this, but more out of indignation than embarrassment. “No, I am a real lesbian, you horrible old man!” she barked. “And yes, I'm still a virgin, though it's no business of yours.”

Despite his age, David moved like a cat, startling Fiona when he grabbed into her left breast, disgusting her when his cock head nosed along the inside of her thigh, leaving a trail of pre-cum slime where it had rubbed her skin. Scaring her when she felt his finger plunged rudely down her slit and force itself inside, probing sickeningly deeply within her cunt until it encountered her membrane.

“Well, looky here,” David said in a low, almost soothing voice. “You really are a virgin, aren't you? And a hot little one, too, judging by how juicy you are.”

He lifted his fingers up to his face, studying the oily coating on them. Fiona's intimate lubrication... her private pussy juice.

To her horror, Fiona saw David smell his fingers, then methodically lick each finger clean. Looking her square in the eye.

“Nice,” he said when he'd finished. “It'll be even nicer in a while, when I'm lapping it up straight out of your cunt.”

The old man paused momentarily, deliberating over his options. A tear of fear and humiliation sprang from Fiona's eye and ran down her cheek, swiftly followed by a second. In response, David caressed her breast tenderly, sending Fiona's mind into a heady maelstrom of conflicting emotions.

“Aw, did the nasty man interrupt you before you managed to crack one off?” David said mockingly. “Never mind, you can cum for me instead.”

With that, he cupped Fiona's pussy and slid his digit back inside, deftly finger-fucking her as his thumb expertly rubbed back her clitoral hood, exposing her sensitive nub.

She let out a guttural groan when his thumb closed over the clit itself and started rolling in exquisite rotation, perfectly timed to coincide with each in-out finger fuck.

Much though his invasion of her privacy had reviled her, Fiona couldn't deny the wonderful sensations the old security guard was able to rekindle inside her. She hated to admit it, but he was managing somehow to make her feel almost as good as if she was masturbating herself.

As if he was listening in on her very thoughts, David squeezed down voluptuously on Fiona's breast and slid a second finger into her, then started finger-fucking her in earnest.

Fiona gasped and bucked as if something was happening to her insides. 'Fuck!' she thought. 'Forget about almost...'

Before she knew it, her orgasm was upon her. Her mind imploded, and a great surge of profound pleasure erupted somewhere deep within. Euphoria overwhelmed her. She couldn't speak, she couldn't think. She felt her pussy turn to liquid, then bubble over...

For a moment, Fiona thought she might black out with the intensity of sensation that had come crashing through her. Admittedly, she had been made to wait for her orgasm, but this was, she had to admit, quite some compensation.

With her mind starting to clear, Fiona thought to ask David about how he had learned to do whatever it was he had just done to her. But before she could gather her words together, she felt the old man's fingers start their now-familiar work on her pussy again.

Fiona reached down between her open thighs and tried to stop David from masturbating her. She closed her hand over his, hardly believing how slimy and wet she had made him.

“That's ok,” she said. “You can stop now. I've had my orgasm, thank you.”

However, David's response was not what she expected. Despite Fiona's pathetic effort to hold his bony but surprisingly strong hand still, he continued masturbating her.

“I don't care,” he said, without a hint of emotion. “I need you to cum again, quickly if you can.”

Fiona was perplexed. “Why?

“Because I'm not a complete cunt, that's why,” he said. “It's been a long time since I popped a cherry, and as I'm no spring chicken anymore, so I doubt very much that another one's going to fall into my lap like this anytime soon. If I time it right, it shouldn't hurt at all.”

The import of what he was saying hit Fiona like a kick in the belly.

“What, you're going to rape me?” she said, aghast. “You'll go to prison.”

David simply shrugged his shoulders. “I'd better make it worthwhile, then.”

With that, he smiled kindly at Fiona, then bent to her chest, where he sumptuously traded kisses from one breast to the other and back again, before latching onto her flat little nipple and suckled on her as heartily as any hungry baby.

At the same time, David intensified his finger-fucking, using his strong, bony digits to work open the channel to her virginal tunnel as covertly as he knew how. He smiled when he noticed her hips beginning to churn around his hand.

'Good,' he thought. 'She's starting to respond. Hopefully, she'll be turned on enough to forget about what's coming next.'

Unfortunately, Fiona wasn't quite yet that aroused, though she was definitely getting there. “But when you came in you asked...” she said plaintively, her mind beginning to swim again with arousal. “You just wanted to... at the same time...”

David recalled his words precisely. 'Mind if I..?' meaning that he had wanted to strip off and get down and dirty along with her; it was she who had misinterpreted it. But rather than ridicule her, he allowed her to believe she had been correct. Because the disgusting old security guard was, by his own admission, not quite a complete cunt.

Fiona groaned when she felt David's mouth transfer to her other breast, drawing her tumescent nipple in over his teeth. Holding it firmly between his incisors, he ravaged his tongue over it for a good few seconds before abruptly breaking off to answer Fiona's heartfelt plea.

“But I do intend to wank along with you,” he said reassuringly. “It's just that I'm going to use your cunt to stroke my cock with.”

Leaving his words hanging in the air, David threw his face back onto Fiona's breast and reclaimed her turgid nipple back into his mouth, lavishing his tongue over it while the fleshy pad of his thumb began vibrantly worrying over her clitoris.

A throaty growl tore through Fiona's lips as she basked in the raw, brutal pleasure. Without warning, the heady rush of a second cum appeared as if out of nowhere, the pretty young lesbian welcoming it without a thought to any consequence.

Recognising the signs of impending orgasm, David moved swiftly to prepare Fiona for her inevitable fate. Scarcely missing a beat of his continued masturbation of her, he lifted her bare feet onto the sink unit on either side of her. Using a puddle of her own making for lubrication, David slid Fiona's bottom forward towards him, until only his hand obscured the magnificent sight of her completely exposed genitals delicately perched on the edge of the sink unit.

Swiftly moving his mouth from Fiona's breast to directly beside her ear, David seductively whispered, “Cum for me, my beautiful girl. Let it crash through you. Cum for me now...”

He then covered her breast with his hand and started squeezing it rhythmically as if she was lactating. Milking her,

This was all the trigger Fiona needed. Clamping her teeth shut, she began trembling violently as the orgasm rushed through her. Moving his sopping wet hand away from her pussy, and without missing a single beat, David slotted the bulbous head of his cock directly into the mouth of Fiona's vagina and pushed himself forward.

The young woman's eyes snapped open as she felt the blunt, unfamiliar cockhead enter her, then bump into her hymen. She felt her insides being stretched. All this happening in the very epicentre of her orgasm...

Fiona gulped in some air and opened her mouth to cry out. But David had anticipated this and quickly sealed his lips over hers, encouraging her to scream into his mouth instead. Which she did, heartily. Once.. twice...

But her third scream dissolved, somehow transforming into a passionate, completely unexpected kiss. David accepted it for what it was and returned Fiona's passion with his own. Though he used the embrace to slide his arms around Fiona's waist and pull her into his hips just as he jolted forward.

Fiona felt her hymen tear, then her insides stretching a lot further than before as David's hefty penis shaft speared through, deep into her womb.

To her surprise, having a cock inside her did feel strange and uncomfortable, but not nearly as painful as she had feared, so David's plan had actually succeeded. Then he brought his hips back, sliding his cock nearly all the way out, before resheathing it into her.

“Aaaahhhh...” Fiona sighed, unused to the sublime pleasures of being fucked. “Feels... good...”

David pulled back once again, then slammed his cock back in, this time completely. Fiona gasped when his pelvic bone crashed into her clitoris, instantly falling in love with the sensation.

His next stroke came moments later, as David started to build up a fucking rhythm in the freshly deflowered virgin. Again, then again, gradually increasing in speed until his cock was soon plunging methodically into Fiona's tight hole, each time with his pelvis thumping into her clit.

Soon sweat stood out on David's brow as testament to the effort he was expending. He was, after all, well past retirement age, but nothing wasn't going to hold back on this golden opportunity: if he was going to die here now, he mused, there's nothing more he could possibly wish for than to be buried in a pretty girl's cunt.

To his credit, David lasted for another five more minutes before the clasping tightness of Fiona's vagina made it impossible for him to hold out any longer. Sweat streamed from his forehead and fell in spatters onto Fiona's vibrant, heaving body. He was breathing heavily now, but even in the heady euphoria of impending orgasm, he could still demonstrate some small semblance of decency.

“Gonna.... cum... soon...” he said, albeit somewhat unsteadily as he continued to pound his cock into the lovely young girl. “Where... do you... want it..?”

Being a lesbian, Fiona had never had to deal with the issue of a man's ejaculation before. But, despite the fact she was being raped, a man's penis was as meaningless to her as dildo – and, looking down her body to where David's cock was pistoning into her recently virgin pussy, this was one dildo she didn't want returned to its box just yet.

“Don't care...” she managed to gasp. “Cumming soon...”

David nodded, assuming she had posed him a question, releasing a shower of sweat over Fiona's perfect young breasts. She peered downward, seeing David's wobbling man-boobs and his unkempt mat of grey pubic hair. This triggered something visceral inside her, a stark reminder of how she was being violated by a man easily old enough to be her grandfather: a long-cherished fantasy rung true.

Fiona could barely remember the last time she had enjoyed three orgasms in a row, but this was promising to be one for her diary—for the “cumming again” she had mentioned was, in fact, referring to herself. Because it was already bubbling away inside her and set to blow very soon.

Lesbian or not, David couldn't believe what an astonishingly good fuck Fiona was turning out to be. He'd been a handsome lad in his time, and his cock had enjoyed no end of tight young fucks, but Fiona's cunt was out there on its own, tighter even than some asses he'd had the pleasure of buggering. It was as though she had a little hand inside her, gripping his shaft as he chopped away in her super-tight cunt.

Sucking away on Fiona's lovely young teat, David bit into her nipple, and she squealed with unfettered delight. A thought rushed through his mind: 'Ah, so she's kinky too? Nice.' But this was immediately interrupted by her snug little pussy tightening even further on him, squeezing David's cock, trapping him in her cunt, restricting his strokes until he could barely fuck his cock head to and fro through along its own foreskin. Damn, that felt sublime!

David had never fucked anyone this tight before. It was like wanking himself off inside her. Try as he might to make it last, this was it, he was done. Beads of sweat spat from his brow onto Fiona's young body as David felt his balls kick, sending his cum squirting out through his cockhead and splashing against the walls of Fiona's womb. He had never been blessed with having creamy-thick semen, his sperm came out more like milk. But what he may have lacked in quality was more than made up for in quantity and power. David's party-piece was to pull out and finish himself off by hand, painting his partner's face, throat, breasts and belly with the copious gouts of cum he managed to pump out onto her.

As for Fiona, she had already been close to orgasm again when David bit down on her nipple. The stab of sexual pain was as unexpected as it was fabulous, firing a bolt of erotic lightning directly through Fiona's erogenous circuitry. She felt her cunt muscles spasm involuntarily, and as David's frantically pulled and pushed to free its movement, this seemed somehow to be directly linked to her clitoris. She had never experienced such an exotic stimulation before.

Then Fiona's senses became assailed with a torrent of sensation. She felt her highly sensitised tits being spattered across with old man sweat, just as David's animalistic grunts bellowed out. His cock seemed to swell within her constricted passage, and a flourish of urgent cock stabs inside her pussy suddenly released jets of liquid squirting fabulously against the walls of her womb.

It was too much. The poor young thing was being overwhelmed by a hailstorm of unfamiliar yet utterly exquisite sensations, and Fiona found herself launching into yet another orgasm. She felt a flood of fluids suddenly and inexplicably expel from her pussy, then fell back, exhausted and drenched in perspiration, in a semi-faint back against the sink unit mirror. Her feet slipped down over the edge, leaving her lying there, naked and slumped, her thighs thrown apart and her breasts and pussy on full, beautifully obscene display.

With her eyes still closed, Fiona slowly emerged from her post-copulatory torpor, completely satiated yet troublesomely undecided about an issue which demanded immediate attention.

“David,” she began sleepily. “What you've just put me through was a complete violation. I've always thought of you as being a thoroughly nice guy. But after this... what can I say? You must know I have to report you to HR and to the police. No matter that I ended up enjoying it. Loving it, in fact...”

The silence that followed was deafening. “Well?” she demanded. “Have you nothing to say about your disgraceful behaviour just now?”

Taking a deep, restorative breath, Fiona roused herself sufficiently to be able to sit up, open her eyes, and confront... no-one. The staff room was completely empty. The door was still closed, and there was absolutely no evidence that David had ever been there. But she could still feel him!

Fiona looked down and saw the stubby end of her dildo protruding from her still tightly clasping pussy, and a few telltale spits of blood on the sink top beneath. It needn't take Sherlock Holmes to deduce that, when she was masturbating, she must have slipped it out of her bag automatically and used it on herself, as she sometimes liked to do. But never before like this. Like that. Down there.

She must have been so horny, so wrapped up in playing with herself, that she had somehow imagined all this! Tossing her head back, Fiona started laughing, uproariously—and carried on laughing, her perspiration- slick breasts jiggling away, until she could scarcely breathe any longer.

Some twenty minutes later, after she had cleaned herself up sufficiently to be presentable again in public, and carefully washed away all traces of her recent activities, Fiona started putting her school uniform back on. Rather disconcertingly, however, her vagina was still resolutely clenched around the dildo and did not seem likely to releasing it anytime soon. She therefore had the stark choice of remaining here until her internal muscles chose to relax naturally, or go home and hope a bottle of wine and a relaxing bath would do the job.

After weighing up her options, Fiona sensibly settled on the one involving at least several glasses of wine. She finished dressing and, after first checking in the mirror that the dildo was not protruding below her immodestly short uniform skirt, she slung her bag over her shoulder and took her first tentative steps towards home.

Walking down the corridor, Fiona realised her gait needed adjusting, or she'd be orgasming every hundred metres or so, considering how the sex toy was stirring her pussy like a wooden spoon in a mixing bowl. Fortunately, the dildo itself was made of pliant latex rather than hard plastic, or she'd be trapped in the restroom for the duration.

Using the length of the corridor to experiment with, by the time Fiona reached the end she had almost perfected a method of walking without rolling her hips in the usual feminine way. Then she arrived at the first of three flights of stairs she would need to negotiate before she could finally cross the entrance hall and make her way outside.

As daunting as they first appeared, though, Fiona arrives at a solution relatively quickly. By holding firmly onto the bannister to balance herself, she reasoned she might simply hop down the stairs—and it worked, at least until the second set, when the dildo began jabbing up into her pussy in a decidedly arousing manner.

However, she did finally make it safely to the ground floor without sparking an actual orgasm, though the trickle of pussy juice creeping slowly down her inner thigh was testament to the erotic turmoil within her that she had sadly failed to subdue.

Taking a moment to gather her wits together, Fiona then looked across the entrance hall to the university's front doors – and beyond that, freedom! Well, an awkward hobble to the bus stop anyway, no doubt followed by a perilous ride home. With the comedy festival in full swing, she was unlikely to have the bus to herself. Then, even after she had somehow managed to negotiate its entry platform, there was likely to be standing room only, where the vibrations from the bus' travel would assuredly travel up her legs, directly through to the dildo lodged in her pussy.

The alternative would be to call an expensive taxi, but getting in and out without displaying herself to the world would be a nightmare.

Fiona's heart sank at either prospect. Nevertheless, she focused her courage and energy to getting home without any further embarrassment, and started making her way across the floor towards the main entrance.

“Goodnight, Miss Fiona.”

The friendly greeting caught Fiona completely by surprise. It came just as she had been passing the darkened security station inside the main door.s When she peered into the position, trying to identify whose voice it was, she was a little taken aback when a small light suddenly came on and she could see a face smiling at her from from behind the glass screen. David's face, the very man she had, just half an hour or so before, been carnally fantasising about.

“Oh, hi David,” Fiona said, her voice sounding distinctly more steady than she was actually feeling. She moved closer to the desk, and could see he had been watching a small array of dimly lit CCTV screens. “I didn't see you there in the dark. Sorry if I looked a bit startled.”

David shrugged his shoulders and smiled. “Oh, think nothing of it, my dear,” he said. “To be honest, you're one of the very few who even bother to acknowledge my existence. Most of the other members of staff just look on me as part of the furniture. You always manage to brighten up my day when you go past, though, you never fail to give me a smile and a kind word. That's why you've always been my favourite and I'll genuinely miss you when I'm gone.”

Fiona had been hurrying as best she could to get away from the university, but David was being even more warm-hearted and friendly than usual, and she found herself genuinely wanting to stay and keep him company for a while.

“So what's all this about missing me when you're gone, David?” she said, her voice laden with concern. “You're not ill, are you?”

Whether she was allowed to or not, Fiona stepped behind the security desk and laid her hands comfortingly on the kindly old security guard's shoulders.

Being an old-fashioned gentleman, David rose to his feet before shaking his head and letting out a quiet chuckle. “Ah, bless you, sweetheart,” he said softly. “No, I'm not dying. In fact, there's a whole lot of life still in me yet. But I am being put out to pasture as of this coming weekend, and being replaced by two young idiots who are patrolling the sports block right now as if they were Yankee marines storming Iwo Jima. So I'm glad I was granted this opportunity to say goodbye to you and thank you for, well, being you.”

Fiona tried to concentrate on what David was saying, but the thought of being caught earlier by these overeager young security guards unnerved her.

Unnoticed by the lovely young academic, David guessed at her distraction. It took him barely a second for him to arrive at the honourable conclusion, which was to volunteer a guarded confession.

Gently taking Fiona's hand, he said, “It's ok, my dear, you were perfectly safe. I made up a story about seeing some kids trying to break in over at the far end of the campus. And... yes, they're still over there, literally chasing shadows.” This last comment was punctuated by John turning his head to check one of the monitors on the bank next to him. When he looked back, he saw that Fiona's face had blanched.

“How? When? What do you mean?” Fiona's eyes looked nervously at the array of screens.

“After that stealing incident a few years ago, HR had discreet cameras installed all over the campus,” David explained, then flicked a switch on his console, and the output from another set of cameras were displayed on the monitors – including, she was horrified to see, two separate feeds from the room she had just been in.

Fiona's heart sank like a stone, and she tried to pull away, but David's strong hands held her fast as he sought to console her.

“Hush, sweetheart,” he soothed. “There's no need to panic. I'm the only one who bothers to check all the various outputs, and as soon as I saw what you were starting to do, that's when I sent Starsky and Hutch away on their wild goose chase. No-one else has seen it, I promise. And no-one ever will; I'm in charge of the recordings, and I know how to erase them. Accidentally, you understand.”

Fiona stared into David's eyes for long seconds, trying to divine what lay there. Men had a reputation for not giving things out of the kindness of their hearts—and with women, that usually meant getting into their knickers. Fiona gave a thin, wry smile: if her knickers were his target, he was welcome to them. They were miles away, safe in her underwear drawer at home.

“That's better, Miss Fiona,” David said, misinterpreting her smile. “I didn't mean to upset you, I just wanted to warn you, because I'll be gone soon and someone else will be overseeing all of this.”

Sensing the old man was being genuine, Fiona started to relax, and even turned her wry smile into a genuinely affectionate one.

“Thanks, David,” she said. “You're a real sweetie.” Then, after a short pause, added, “So you watched me, then?”

He didn't need to answer; it was written across David 's face.

Fiona should have been shocked, but she couldn't help chuckling at his expression. “You naughty boy,” she said, jokingly.

“Hey,” David said, smiling. “You're calling me naughty, but you're the one who was merrily jilling away in work!”

Fiona was surprised.

“Yes, I know what jilling is!” he said, sardonically. “I wasn't born an old fart, you know, I've had a life. I've been a hippie, a drummer in a rock band, plus a host of other things. You youngsters think you invented sex, but we were at it almost before we were out of short trousers. No AIDS or chlamydia back then, if a girl was up for it, you could fuck each other senseless if you had the energy. Drugs were organic too, unless you dropped tabs or were into the hard stuff; nothing like today, where kids get blasted as quickly as they can on whatever snow or GM crap they can lay their hands on.”

David caught himself before he rambled on any longer.

“So yes, my darling Miss Fiona,” he added, “I did watch you strip off and masturbate, and what a fabulous sight it was. That David you were talking to on your phone is a lucky guy, you can tell him that from me. If I was twenty years younger, I'd be fighting to steal you from him, believe me.”

At first, Fiona couldn't quite understand what he had been talking about. But then the penny dropped: when she had been carried away by lust and had that all-too-vivid fantasy about him, he must have thought she had been sexting a boyfriend. Well, that saved a lot of awkward explanation, she was relieved to conclude.

Then, after a pause for thought, David continued, “You know, Miss Fiona, that problem with your vagina? My wife suffered the same sometimes. If she was enjoying herself a little too much sometimes, her pussy would just lock in spasm. Whether it was my finger, one of her vibrators, or especially when we were fucking, she'd just suddenly clamp down on me. It took me ages to work out how to relax her again.”

Rather than feigning outrage at his impertinence, Fiona simply swallowed her pride and accepted the fact that David had been privy to, well, everything she had been doing since his shift had started and he had first manned the CCTV console that day: her stripping naked, her fabulously bohemian masturbation... her hobbling all the way downstairs to here with a sex toy stuck up her quim.

“All things considered,” she said, “I think we can dispense with the 'Miss Fiona' bit, don't you? So tell me, David, you're married? You've never mentioned this before. You can tell her from me, she's a lucky girl for having you – and I'd never dismiss you as being an old fart. I find older men very attractive, in fact, so she'd better watch out!”

David gave a wan smile, and Fiona immediately realised she had unwittingly stepped right onto a raw nerve. “My darling Fiona,” he said evenly. “Thank you for for those kind words, but I regret to inform you that my sweet Susan died just after last Christmas, after having put up with me since before either of us had been old enough to grow pubic hair.”

Hearing this, Fiona's heart went out to David. Without saying a word, she slid her arms around him and drew him into a warm, affectionate hug. Not that her act was entirely altruistic: nestling her face into the old man's broad chest gave Fiona such a wonderful feeling of comfort and safety, she soon found herself pressing her whole body into his. Even when she felt David's erection developing between them, she didn't feel threatened; if anything, she just took it as a compliment.

Being a gentleman, of course, he apologised and tried to pull away, but Fiona hugged him even tighter, telling him not to worry, that it was perfectly natural.

Fiona felt David relax, and for the first time in her life she felt a man's penis as it hardened against her, albeit through his clothes.

“Are you sure you don't mind?” David asked. “That thing's got a mind of its own, I'm afraid; especially after seeing you earlier, it probably thinks its luck's in.”

Fiona chuckled, inadvertently caressing David's tumescence in gentle vibration, causing him to stiffen even further.

“Ooh, I felt that”, she said, chuckling even more. “I think I'm the lucky one – or your wife was, rather, having you all to herself for all those years.”

David was silent for a while, content to be allowed to feel his erection pressing against a pretty young woman again. Someone he admired and cared for, someone he felt comfortable reminiscing about his lost wife with.

“You know, Fiona,” he said quietly. “Thanks to Susan, I lost my virginity even before I knew what the stiffies I'd started experiencing were properly for. And she lost hers at the same time, of course: just two kids, innocently rubbing their bits against each other, simply because it felt nice. After that, we just couldn't get enough of each other. Never mind rabbits, we were fucking like bonobo monkeys almost every day until her heart finally gave out.

“We loved each other so much, we were happy to see the other with different people. With other couples, too; as many as could fit on our oversized bed sometimes. The only rule we had was that we did it where the other one could see.

“I loved watching her being fucked, seeing her from different angles; the little things I didn't notice when I was fucking her myself. The way her breasts seemed to blossom when she was about to orgasm, the way her toes curled when she had a large cock enter her from behind.

“She loved watching me with other girls, too. Lying there masturbating as I entered other girls in front of her - I adore watching you girls jilling yourselves, or each other, it's a beautiful thing to see. Lying there while a girl I was fucking ate her out at the same time, or sat on her face so she could lick them out as I fucked her vanilla-style. Putting her face in my crotch and eating whichever of a girl's holes I wasn't fucking.

“Damn, I loved that woman so much I thought my heart would crush in my chest when she left me. Some nights I still do.”

Fiona didn't quite know how to respond to this, so she just did what came naturally: reaching up on tip-toe, she gently kissed David on the cheek. Then, after a moment's consideration, just once, softly, on his mouth.

“She sounds like an amazing woman,” Fiona said with undisguised admiration. “I think I'd have happily spent hours making love to her, or having her make love to me.”

Then a thought entered mind. “The spasm thing you mentioned,” Fiona said guardedly. “I hope you don't mind me asking, but just how did that manifest itself with her? And did she ever find a way to prevent or even cure it?”

David discreetly disengaged himself from Fiona's embrace: to answer her, he felt he needed to address her directly.

“You're asking for yourself, I assume?” he said. “Sadly no, I'm afraid we never did manage to fully cure it, though medicine has advanced so much during the past decade or so, that they might well have come up with a solution by now. However, I did actually stumble across a method which relaxed her pussy muscles and allowed whatever, or whomever, had become trapped in her to slide out again.”

Unsurprisingly, Fiona's face lit up on hearing this, but David had a little more to say.

“Don't get your hopes up just yet, though, my lovely lass,” he added, somewhat ominously. “What I did was rather intimate, and you'd need to trust me implicitly. Plus, of course, there's no guarantee it would even work with you.”

Fiona considered this for a whole two seconds before deciding.

“Anyone else would have used the situation to take advantage of me,” she said. “But here you are, actually trying to talk me out of it. So I think the issue of trust has already been answered.

“As to the question of intimacy, you've watched me naked and masturbating to multiple orgasms, and here you are, being as gentlemanly as ever, knowing full well that I'm standing here with a dildo stuck up my pussy, which is, quite frankly, starting to get on my nerves. So how do you want me, just bare-bottomed or fully stripped?”

David admired Fiona's candour, and was equally forthright in his response.

“I'd be lying if I said I didn't want you in just your birthday suit,” he said, smiling. “But just skirt off and shirt unbuttoned would be fine. And kneeling up on the desk, I think, if you don't mind.”

At that, the old security guard stepped out from his station, closed and locked the entrance, then returned to find Fiona trying vainly to clamber up onto the desk.

“That damned dildo getting in the way?” he asked. “Don't worry, I'll lift you up in a moment. But first, do you see this monitor showing my two young colleagues patrolling the sports block? Try to keep an eye on it. They're a good twenty minutes away, so if you see them heading back just mention it to me. But you can relax; whenever I've sent them out there before, they've always found an excuse to stay out for at least an hour, and usually longer. Now...”

David stepped up to Fiona and, squatting down, he wrapped his arms around her legs before standing up again, carefully lifting her with him and straight onto the desk.

“Kneeling should be fine,” he reminded her, “but do try to keep your thighs well apart, ok? Now, do you want to undress yourself, or shall I do it for you? Oh, and I'll need you to orgasm, so just let yourself go and enjoy it as much as you can. And don't worry about me trying to fuck you afterwards, I respect you too much to try to do that. Now, your clothes...”

Much against all she held dear, Fiona found herself being aroused by everything that was happening. When David started unbuttoning her school blouse, her nipples were already achingly erect – and, realising her naked pussy was now on a level with his mouth, obscured from his view only by her thin school skirt, she felt a drop of juice escape from her pussy and run tickling down her inner thigh.

For the life of her she couldn't understand why she was being affected her like this; no man had even come close to turning her on. But Fiona then realised, this was no normal man. This was an old and handsome man. David, the man she had just enjoyed having a vivid fantasy about. She was now feeling so horny, she felt she was about to burst.

With her blouse fully unbuttoned and her school tie unknotted and now simply draped around her neck, David gave the monitors a final glance, just to reassure himself they would not be disturbed. He then deftly unfastened the catch and zip on Fiona's skirt. A muted “swoosh...” of fabric later and it promptly slid down to the desk.

The young lass was now naked from the waist down, and standing before the only man outside her family who had ever mattered to her, her bare pussy directly level with his mouth, so close she could feel his breath gently lapping into her pubis. In short, Fiona's senses were as alert as she had ever known; having had that damned dildo stirring away in her pussy for all this time, the horny young thing was a powder keg fit to explode. She daren't even kneel down as requested, just in case.

“Ah, what a pretty little cunt you have,” David said, then slid his hands up under Fiona's blouse and swept both sides apart as he might a pair of curtains, rending her as naked as makes no difference.

“Pretty little tits too,” he added. “But, of course, I've already seen those, when I was watching you as you fucked yourself upstairs”.

David's words were designed to arouse Fiona, but being stripped naked and in closely intimate view of her fantasy man had already brought her close to boiling point with lust.

But it was when he started caressing her breasts and rubbing her nipples generously between his fingers that she finally succumbed, cumming loudly and flamboyantly right there in front of him.

Fiona was understandably a little embarrassed when she descended into the aftermath. But David would hear none of it.

“Nonsense,” he said. “A woman in orgasm is the most beautiful sight and sound in the world. I was already hard, but that wondrous display has made it almost painful. My old boy's positively straining to get out of my trousers. Would you mind very much if I released him?”

Fiona shook her head in agreement, unsure she could trust her voice just yet. After all, she thought, what were a man's genitals to her? As it transpired, that may well have been true of the rest of the male population, but when David unceremoniously dropped his trousers and boxer shorts to the floor, her mouth dried and her heart quickened when his pale, long and slender penis sprang out and stood erect from his groin.

His cock didn't look at all as gnarly and loose-skinned as it had in Fiona's fantasy, but smooth and surprisingly elegant, she thought, as if it is had become polished over the years from pistoning in and out of all those women the lucky couple had been sexually adventuring with. Against her natural instincts, she found herself quietly envying them.

Without actually realising she was doing it, Fiona was gazing longingly at David's erection when his soft voice stole into her quiet reverie.

“You're welcome to feel it inside you, if you like,” he said. “But let's get that pesky dildo out of you first, eh? That orgasm was exactly what I'd asked of you, but it came just a wee bit too quickly, before I'd managed to get ready for you.”

Before he could finish, Fiona blushed and meekly apologised. But, ever the gentleman, David would hear none of it.

“Don't ever make excuses for having an orgasm when you're with a man,” he chided Fiona with disarming charm. “Especially when it's been none of his doing. But I will need you to have another orgasm, if you'd be so kind; I promise to be ready for you this time!”

Then, after glancing at the screens once again, David continued.

“So tell me, my lovely young Fiona, would you prefer to jill yourself off, or would you like me to do it for you? If you squat down, I can fondle your tits while I finger you between the legs. Or you can remain standing, and I can kiss you like this...”

As he said it, David leaned in and delved his tongue directly into Fiona's pussy slit, licking through her until he had reached the intrusive dildo, lapping along the slender and deliciously moist fleshy leaves flanking the groove itself, before retreating to worry his tongue back and forth across Fiona's pea-hard clit.

Brought gasping into a near-swoon, the sexy young lesbian was forced to grab David's head, holding it in place in order to steady herself; though in doing, so she had clamped his face firmly against her cunt, seemingly encouraging David to bring her off on his mouth.

Accidentally guided there or not, Fiona's favourite old man did not let her down: he lapped at her cunt, then sent his hand up to her breast to caress and fondle her there.

Within minutes, and already approaching the height of arousal, Fiona started showing imminent signs of her impending orgasm. But David was ready for her this time: sending his free hand around her rear, he sculpted her firm young buttocks before scooping down over her anus and liberally coating his fingers how the copious fluids leaking from her cunt.

Then, when Fiona bucked and seized fully into her climax, he promptly thumbed open her anus and pushed two well-oiled fingers as deeply into her rectum as they could physically go.

Fiona found this uniquely and profoundly erotic, and pulled David's mouth up even harder against her cunt. But this was pure serendipity, because the fingers in her bottom had already massaged through her anal wall to locate the dildo, then stroked upwards to cap over the blunt end of the sex toy.

Then, quickly moving his other hand down from her breast to slide between her thighs, David grabbed the end of the dildo protruding from her vagina.

As he suckled on her turgid clit, Fiona found this all too stimulating and she vaulted into yet another climax. Coordinating his actions perfectly with the ebb of her orgasmic spasms, he pushed and pulled both ends of the device until, with a final liquid rush, the dildo at last slid free. Fiona buckled to her knees in complete exhaustion and toppled forwards into David's arms.

Fiona must have drifted into unconsciousness then, because she woke up some time later, still with her face in David's chest, but sitting on his lap, on his chair... with his erect penis poking up between her thighs!

“Did you just put that in me when I was asleep?” Fiona asked, though she surprised herself with her ambivalent tone. After all, she was a true lesbian; if he had taken her virginity while she had been unconscious, she was, if anything, simply a little miffed that she had missed such a unique experience. But, as it transpired, she had nothing at all to be concerned about.

“I'll have you know I don't put my cock anywhere it hasn't been given permission,” David said, somewhat disgruntled, and sounded more than a little hurt. “You're young and very attractive. You're also naked, and I have the smell of your body in my nostrils, the taste of your pussy in my mouth and juices from your quim still drying on my fingers, and I haven't had sex since the day before my wife died half a year ago. So I apologise for my erection, but I had to put it somewhere, and that's where it felt most comfortable and would disturb you.”

Fiona absorbed every word, then, after a somewhat charged, contrite silence, curled her body in against David's chest and touched his face gently before reaching up and giving him a lengthy, loving kiss.

“It was just a question, that's all,” she then said. “I didn't mean anything by it, honestly I didn't, and I wouldn't upset you for the world. I wouldn't have minded even if you had put it in me, after all you've done.

“Now... I have a confession to make. I'm a virgin. More than that, I'm a lesbian, and a virgin, at least where men are concerned. I have no boyfriend, and the David you'd assumed I was sexting with upstairs was actually someone I had fantasied about for quite a while. An older man. Called David.

“You,” she said, slipping her hand between her legs and around David's penis, which swelled and stiffened perceptively at the contact. “Now, you have a car, don't you?" she added with a developing smile. "Then might I suggest I call those two idiots of yours on the radio and tell them to get their arses back here, because I have a job for you at another site; where I'll need you for the duration of your shift, at least? Then, if you have no objections, you can drive me back to your place and, well, we'll see what might develop between us there.

“Oh, and that recording of me fantasising about you giving me the fuck of my life? Before you delete it, copy it onto a flash drive and slip it in your pocket, with my compliments. Now, I need a bath or a shower, so would you mind if I waited for you in your car after I get dressed? That is, if you don't mind it smelling of horny girl and extremely wet pussy, naturally.”
