Vanessa was a teacher at a private high school in the US, specialising in international organisations and relations. She was in her early forties, with an older boss she not only admired but had secretly begun to lust after. In the absence of a regular partner, her raging libido was threatening to overwhelm her at times, and she struggled to control herself at work whenever he looked at her. She hid it from her colleagues and from her boss himself. She hoped that he was also just behaving professionally, though, and was really suppressing a burning desire for her body.

Simon was a respected professor in his sixties, with a deep and wide-ranging knowledge of world history and politics. He was British, but visiting the US for a month or so, and had no plans for his final week. He had been in regular contact with Vanessa's boss, who had once, long ago, been his student in London and who now asked him to come and lecture at his college.

Simon was single now and still trying to overcome the death of his wife some time ago. They had had a long and very active marriage, and he was beginning to feel the absence of physical contact now, after several months.

Simon and Vanessa were put in contact via email at first, and she suggested that, being British, he could talk to her students about the history of the British Empire and its deep impact on global politics ever since.

That sounded like an interesting challenge to Simon, and their email exchanges developed the ideas, until they felt they needed some personal, face-to-face discussion. The outline was for a series of three lectures, covering the consolidation of the Empire under Queen Victoria, the appalling atrocities and ruthless exploitation both of peoples and of natural resources, and the important lessons to be learned by present-day America.

He began to discuss matters with Vanessa through Zoom meetings, and as well as finding her very intelligent and efficient, he had been taken by her appearance too. She had the brightest of eyes and a luscious-looking mouth. He did not have a good view of her body, but he caught occasional hints of very full breasts when she leaned earnestly towards the camera, and he found her very attractive.

In their final Zoom meeting, when they arranged to meet later in person, Vanessa removed her sweater, presumably because she was hot, but her low-cut top showed more than he had seen before. He would never impose himself on her, but he felt there was some reciprocal feeling between them, and her wide smiles encouraged him to think so.

Their first face-to-face meeting at her college was a little overwhelming, and both felt inhibited, not wanting to overstep any invisible boundaries. Apart from discussing the content of his lectures, though, they learned more about each other's circumstances at each meeting and began to relax in each others company day by day.

In private, afterwards, each of them fantasised about the other. Their meetings became more personal and flirtatious, though they both maintained professional decorum. It was clear that there was a certain sexual chemistry between them, and slight touches became more and more common; they were both highly sensitised to the slightest contact, which sent tingling thrills through their minds and bodies.

Vanessa helped Simon with practical preparations to give his lectures from a desk in the library, close to her classroom. She watched and listened as he talked so authoritatively about his subject, which was close to her heart, and observed her students' reactions; she was sure that some of her female students were swooning over this sixty-year-old man. He was well built, after all, and at six feet, her head hardly reached his chin.

Her lust built through his first lecture, and after the second, she had to relieve her tensions by masturbating furiously in private in her classroom after Simon had left. Little did she know that he had felt the same in the privacy of his hotel room.

After the third and final lecture, the students all left, thanking both of them profusely, and Vanessa stayed with Simon in the library to help him pack up his equipment. They both knew that this might be the last time they ever met alone and wanted to make it last.

She had provided a celebratory bottle of wine for them to share in the library, but no other staff were there. They sat and talked flirtatiously. Vanessa removed the sweater she wore over her light dress, and Simon removed his tie, unbuttoning his shirt.

Vanessa complimented him on his lectures and thanked him for giving his time to her and her students, placing the palm of her hand on his smooth chest. He placed his hand over hers and smiled down at her.

She said she was sure that some of her female students had found him very handsome and looked up into his face to add, “I certainly do, Simon!” She blushed a deep shade of pink as she said this, and her big, wide eyes roamed over his face. They had a pleading quality, and he thought he knew what she was silently pleading for.

They stood face to face, sipping their wine, and slowly inching closer together. She reached up, running her hands through Simon's long curly hair. She stroked his cheek with her thumb while her hand guided his face down to meet hers, and they kissed for the first time. At first it was an affectionate kiss on his cheek, but soon became a full kiss on the mouth, their tongues darting and flickering together, tasting each other for the first time.

He complimented her on her shapely curves, and she complimented him on his fitness, for a man twenty years her senior. They discussed their private lives (or lack of them), and Vanessa complained that it was so difficult to find a cultured and sensitive man, who genuinely knew how to please a woman. Her eyes flashed at him as she spoke, then looked demurely down.

Simon nodded. “I'm sure that is true, Vanessa. I know you admire your boss, and he is only ten years your senior, so you might find him sensitive to your needs, if you can only break the ice?” he said.

“Being realistic, Simon, I don't think he can give way to that, without damaging relationships amongst the staff here. Probably, they ALL lust after him!” said Vanessa.

Simon said he could understand that, but if he were her boss, it would be difficult for him to resist her.

She pressed herself against him, her head below his chin, and sighed, “Simon, could you give me the benefit of your experience? There would be no commitment, because you are leaving very soon, but I would love to feel the experienced touch of an older man. I know you are sensitive and considerate and would treat me kindly.”

Simon was a little taken aback by the frankness of her words but felt a swelling pride in himself and in his cock at the thought of this beautiful woman pressed against his body, making herself readily available to him.

“I have to leave tomorrow!” he said, hesitatingly, “but... we are alone here, aren't we?"

She assured him that everyone else had left, and she had the only keys, being trusted to lock up at the end of the day.

“There's no time like the present,” said Vanessa and looked up at him with her wide eyes shining, while her breasts pressed harder against his chest and her hands slipped around his body to pull his hips against her belly. “Can I feel something stirring down there, Simon?” she smiled.

He nodded and grinned. They slowly undressed each other, their eyes savouring each revelation, and talking constantly, a little nervously.

He was a little overawed by her curvaceousness, not only her ample breasts but also her hips and ass, and she shuddered as he ran his hands over every area he revealed, complimenting her throughout as he reduced her to complete nakedness in front of him. He noted her erect nipples and her pale areolae; he rolled her panties over her rounded ass and extracted the damp crotch gently from between her thighs. He also noted her waxed pubic mound, seemingly freshly done, and wondered if she had prepared herself specially for this very occasion.

She followed suit, blushing slightly at her own nakedness, and removed his shirt before kneeling at his feet to unbutton his jeans, She gasped with shock, and perhaps delight, when she revealed the swollen head of his cock (and an inch or so of hard shaft) already protruding above the elastic waistband of his briefs. She sat back on her heels to admire that view, then gingerly stretched the elastic to free him, and lowered his briefs to the floor. In doing so, her cheek brushed against his exposed cock, and as she passed, her pointed tongue flickered out.

She sat on her heels below him and looked upwards. “My God, Simon," she said, “you are... large! In every dimension, I mean... this is beyond my expectations of you!”

They were both completely naked in the library now. Vanessa wondered whether she would ever be able to work in the library again, without the vision of Simon's cock haunting her, teasing her, making her wet.

She sat up slightly to cradle Simon's cock between her large breasts and press them around him, then bent forward to take the bulbous head between her lips and suck loudly, looking up into his eyes. She did not take his cock deeply but slurped noisily around the head, and her moans vibrated his cock while one hand held the shaft, squeezing gently, and the other teased his tight balls with the saliva which dripped down to them. She squeezed and stroked them with her wet fingers.

Simon reached down to cup her chin and jaw, holding her still for a moment. He was sorely tempted to thrust his cock deep inside her willing mouth, but instead he lifted her from his cock. She looked up in surprise, her beautiful eyes questioning 'why?' and Simon just said, "I don't want this to finish yet, Vanessa!”

He guided her to her feet and bent his head low to kiss her deeply on the mouth, and their tongues danced together, licking and playing. Then he turned her head aside, and his tongue darted around her ear, probing briefly inside before he took her earlobe between his lips and sucked gently. He played with it as if it were her clit, sucking and flicking it with his tongue, occasionally nipping it gently between his teeth.

“Oh, Simon!” she said, “that is sooo sensual!”

He grinned and said, “ I know what would be even more sensual!” Then he lifted her onto a Library desk, and guided her to lie back, with her knees dangling over the edge. He gently spread her thighs apart, and stroked them with his long fingers, lightly running them upwards from her knees, over the soft skin of her inner thighs, and touching her outer labia briefly before returning to her knees.

He studied her in detail. Her labia were shaped like orchid petals, mauve in colour, and already dripping wet, swelling and opening under his delicate treatment. He slowly teased them apart, running his finger the length of her slit, to reveal the bright pink interior leading up to her darker pink clit, already proud and engorged. He did not touch her yet, but parted her inner lips to seek out the darker well of her cunt, overflowing with slick juices.

She wriggled with impatience. He told her to relax, lie back, and just enjoy what was to come; she groaned and bit her lips, saying, “Please, Simon, I want you to fuck me soon.”

Instead, he dropped his head between her thick thighs and his wet tongue followed the same route that his fingers had before. But when his mouth reached her pussy lips, he lingered there, scenting her and tasting her arousal. He licked each of her outer labia from back to front, then more firmly, her inner pink lips, before his mouth clamped firmly around her swollen clit.

She gasped as he sucked her clit between his lips, just as he had with her earlobe, and flicked it with his tongue. Pressing harder, he introduced one long finger just inside her cunt, while he continued to tease, flick, suck and nip her dark pink clit.

Vanessa was becoming more and more agitated, moaning loudly and rocking her hips against him. She reached down to hold his head, and ran her fingers through the curls of his long hair. He knew that she would soon reach a climax, and his finger moved deeper inside her cunt, to massage her inner wall and find her most sensitive spot. The pace quickened; he moved his finger in and out, while his tongue flicked and his mouth sucked. His spare hand moved up over her belly to reach one breast and play with the nipple, pinching it tightly.

Her climax came suddenly. She squealed and shook, while her cunt gripped his finger and convulsed around it. Her body trembled, while Simon stopped all movement, and allowed her climax to pass before removing his finger from her and lifting his head from her pussy.

She looked down at him and he smiled as she said, “That was wonderful, Simon! Thank you so much. When I have recovered a little, please fuck me slowly and gently, at least at first; I think I am too sensitive to accept your cock at the moment... it might be painful!”

Simon said, “It shouldn't take too long, if I am gentle. I do need to get inside you with more than my finger, though! Sit up now, on the edge of the table, and we can hug for a minute or two.”

They did, but Simon would not let her touch his throbbing cock yet. If she was allowed to, he was sure she would quickly bring him to orgasm too, and he wanted to delay that as long as possible. This evening would be their first, and their last, after all.

They both calmed, but Simon remained hard, thinking of entering Vanessa's beautiful pussy, and feeling her large breasts press against his body. As she sat on the edge of the table, his hard cock pressed against her belly, and she looked down to see how far it might penetrate her. She gasped with anxiety, feeling his cock , as hard as steel, but pulsing, throbbing, twitching against her belly.

Vanessa said, “ It isn't just the length, Simon, but the thickness! I can feel your blood pumping through my hands when I hold you tight, and I know it will be a tight squeeze into my pussy, even though I am already so wet for you. I would like you to enter me very, very slowly”

“I will,” smiled Simon. “I want you to feel every inch of me as I enter you.”

She sat at the edge of the table, leaning back a little, as Simon positioned the swollen head of his throbbing cock between her outer pussy lips, and moved it slightly back and forth, to coat it with her slick juices.

She trembled with anticipation, and tried to suppress her feelings that her orgasm would return even before Simon fully entered her!

Simon was true to his word. He positioned himself at the entrance to her cunt, and edged slowly forward, while she threw her head back and tried to breathe calmly. However, she squealed as the head, the first inch, located inside her, and opened her wide for what was to follow.

“One,” Simon said, then looked down and edged further forward, saying, “Two,”

then a little further...

“Three.”... and Vanessa moaned as she felt his cock opening her wider.

“Four,” he said, and smiled as Vanessa gasped, “How much more, Simon!”

“Five,” he said, and she moaned again.

“Six,” he said and looked down to see the remainder waiting to enter her.

“Nearly there!” he said... “Seven.”

“Oh God!!!” moaned Vanessa as she felt the thick head throbbing so deep inside her, deeper than anyone had ever been before, she thought.

Simon may have exaggerated a little when he made his final push into her, announcing, "Eight!" But by then, the root of his cock pressed hard against her swollen red clit, and the bulbous head was pressed against her cervix.

Vanessa could feel his whole length inside her, throbbing and pulsing against the tight walls of her cunt. She had never felt so FULL in her life. “That feels SOOO good, Simon! But, please be gentle at first, until I've adjusted to you.”

“Don't worry!” he said and raised her body from the desk to clasp her close to him, then raised her legs to wrap around his hips. Somehow, Simon stood, with Vanessa deeply impaled on his strong cock, while she clung to him like a limpet, arms and legs wrapped tightly around him.

She looked up, with her moist eyes shining quizzically, and said, “What now!?”

Simon did not answer but turned to walk towards the library door, supporting her with his strong arms and cock. He opened the door and moved steadily down the corridor to her classroom. She felt every jolting step he took, putting pressure on both her clit and against her cervix, and her erect nipples rubbed against his body. But she loved every step and relished the slow journey to her classroom.

He opened her classroom door, saying, “I want to fuck you here, Vanessa, so that every day, you can look around and imagine that your students, your colleagues, anyone, might be watching and envying you and me!”

Simon laid Vanessa down on her desk, in front of the classroom, to relieve his body of her weight, and slowly withdrew his cock from her depths, eliciting a long, slow howl of delight as she imagined everyone watching them. They would see his long cock, shining with her juices as he withdrew. She squealed as Simon's cock sprang up to its vertical position, and splashed drops of their juices up over her belly.

“Simon, I want you to fuck me here, and I want it to be never-ending,” whispered Vanessa sweetly and waited for him to enter her again.

But he did not do so immediately...

“I do want you to remember this forever, Vanessa,” said Simon and guided her to roll over and kneel on her desk, then to drop onto all fours, with her beautiful round ass raised high, waiting for him. He stood at the end of her desk, the perfect height to fuck her from behind, and pulled her wrists back between her knees so that she was immobilised. She dropped her shoulders to the desk, and gasped as she turned her head to one side, realising how completely she was now exposed to Simon and to anyone else who might see them.

Simon held her wrists tight and her ankles were pressed between his legs so that her thighs and ass would grip him tightly. He looked down and positioned the head of his cock between the dripping wet, open lips of her pussy, engaging with her cunt.

This time, he did not enter her so slowly or count the inches, but pulled back on her wrists as he slammed full depth into her, and she screamed loudly.

He began pumping rhythmically in and out of her, looking down to see his slick, shiny cock thrusting in and out of her cunt, forced wide open by his thickness. He loved to hear the sounds of his belly slapping hard against the wetness of her ass, time and time again, with every long, deep stroke. He grunted out loud with every animal thrust into her.

The grunts and rhythmic slaps against her ass became almost hypnotic, like the ticking of a metronome, slowly increasing in pace.

He wanted to keep pounding into her forever, and so did Vanessa.

But she was getting louder and louder in her calls for him to cum, pleading with him to fill her. Her voice reached a crescendo, then she began to shake and tremble again, but this time, her tremors spread through her entire body and caused the desk to shake and rattle beneath her. She begged out loud, with one last call, “Cum, Simon, cum NOW! Fill me with your cum... pleeease!”

He could not maintain his detachment any longer, and the blood pounded in his temples as he put his head back and roared like a lion, with one last full, deep thrust into her, before he stopped still. His accumulated cum began to spurt inside her, and she could feel every pulse, every throb of his shaft, as it was delivered so deep into her. Those feelings re-energised her orgasm, and a second (or third) wave of tremors shook her body. She gasped and panted, fighting for breath, and began to cry with relief, sobbing with the release of pent-up emotions.

Simon looked down and could see his cum overflowing from her, escaping to run down the insides of her thighs to the desktop. He knew that when he withdrew, it would be like removing the cork from a bottle of champagne, and his cum would flood the desk.

As he slowly withdrew, Vanessa moaned sleepily but jolted when he left her completely. She felt the cum flow, but knew that so much more remained inside her. Nevertheless, she felt very empty now that Simon's long, thick cock had left her.

The experience of being fucked and filled so completely was quite overwhelming. She collapsed face down, full length along her desk, at the front of her classroom, as Simon finally released his grasp on her wrists, and stood back

He had to sit down, himself, in her chair and observe her. She truly was beautiful, he thought, and he felt proud to have pleased her so completely.

When she recovered sufficiently to sit up on the desk and face him, her flushed face beamed at him, and she thanked him for treating her so well. He thanked her for allowing him to follow his instincts.

They both stood, still naked and sweaty, to hug tightly face-to-face and comfort each other. They knew that Simon was leaving the next day and that they would likely never meet again, but it had certainly been a memorable encounter.

Simon had had a 'bonus' reward for his lectures, and Vanessa had retained a memento of the occasion in her classroom.

Although they tried to clean it away, the pools of cum on her desk had made an indelible stain at one end. It would remind her of Simon forever, and often, in the future, she would sit at her desk and idly stroke the stain while looking out at her students or her co-workers.

She would think, “If only they knew! If only they could have watched us! If only Simon could fuck me again.”
