In the course of the following tutorials, Simon taught Ramona a great deal about chemistry—how various elements can combine to produce exciting new materials, either in slow, gentle ways, or sometimes in sudden, explosive ways. They explored a similar variety of experiences in their own personal and sexual interactions, and the “chemistry” between them grew ever stronger and more complex.

Each week, Simon set an academic task for Ramona to complete and submit to him in advance of their next tutorial. She worked very hard and diligently at these tasks, and her efforts were duly noted by her parents, who ensured that she worked under exam-like conditions. They were very impressed with her commitment and determination to please Simon, though unaware how far she took that determination in private!

Simon was also genuinely impressed with her work, and could see significant academic improvement from week to week. Ramona requested her 'reward' for her work each week, usually in the form of exploring new ways to achieve an orgasm for herself or for Simon, or usually both.

Simon complied willingly with any requests, but their time together was very limited, so their sexual encounters were sometimes more hurried than both would have liked. Her academic work always took priority, so she endeavoured to present good work which always met Simon's high standards, leaving as much time as possible for her to be rewarded.

The Second Tutorial.

In their first week, Ramona had simply asked for Simon to fuck her. She was not a virgin, but her sole experience of full sex had been very cursory and unsatisfactory. She had practised and developed her oral skills with local boys, and demonstrated those skills to Simon in their very first tutorial. He had returned the compliment by going down on her. That had been an entirely new and very satisfying experience for her.

Now she wanted full penetrative sex and Simon had cautiously agreed. He knew that she had only had one (unsatisfactory) experience, with a young boy, who had (technically) taken her virginity, though perhaps 'stolen' would be a better description, as he had given her nothing in return!

Once Simon had approved Ramona's work, they relaxed and settled down to address the reward she wanted. He felt that they should adopt a simple Missionary position, for her first real experience, and take as much time as possible. Ramona excitedly agreed to that, and almost tore off her clothes to stand naked in front of him, claiming she would save time.

Simon was amused by her impatience, but it was clear that she was fully prepared; her pussy was already leaking its juices, and opening to accept whatever might be offered. She undressed him with the same impatience, only slowing a little to take care as she removed his briefs to reveal his erect cock.

She had studied him closely before, but this time she stared wide-eyed and said. “My white girlfriends always talk about 'BBC', but I will have to tell them about your 'BWC', I think.”

“I think I understand the modern jargon,” said Simon, “though in my home town of London, 'BBC' means the British Broadcasting Corporation!”

They both laughed and Ramona lay back on the rug on the floor, spreading her glistening thighs to welcome Simon, as he knelt between her thighs, then sat back on his heels. He stared fascinated by her bright pink slit, gleaming wetly at him from between her deep black, open pussy lips.

Then he reached forward, to raise her ass up onto his thighs. His cock pressed against her slit, and he slid himself up and down, to coat himself in her juices; she jumped each time the head of his cock pressed against her clit.

When he was well lubricated, he lowered her to the floor again and covered her with his body. She shuddered in anticipation as she felt the head of his cock engage with her vaginal opening, and one hand reached down to feel the length and thickness that was yet to come.

“Oh Simon,” she said, “please be gentle with me. It is quite frightening to think of that enormous cock forcing its way inside me! You are so much bigger than the boy who fucked me before.”

“Don't worry,” said Simon, “I will be gentle, at least at first. You may want me to become more forceful once you have adjusted to me.”

Simon slowly edged the head of his cock inside her wet cunt, and inched further and further forwards, until the thick root had stretched her wider than ever before, and his body pressed firmly against her throbbing clit. He lowered himself onto her, his chest cushioned by her young breasts, and kissed her passionately, their tongues entwining and dancing between their lips.

He lay still for a minute or two, and Ramona felt the firmness of his cock by squeezing her vaginal muscles around him, while she wrapped her arms around his body and clasped him close. But she could not remain still, and her hips began to rock subtly beneath him, encouraging him to thrust in and out of her.

Simon understood all these signals and withdrew his cock to almost full length, before slowly entering her again, and again. The movements were so smooth, but despite the extreme lubrication, the sensations both felt were delightful; nerve-tingling friction of every fibre in Simon's cock and Ramona's cunt, as they pressed through against each other.

Ramona began to gasp with every thrust into her, and she wrapped her legs around Simon's back, encouraging harder and harder clashes. The speed, depth and force of every thrust steadily rose, until Simon was hammering into her with massive energy, and every clash of his body against her clit began to cause Ramona to squeak out loud.

“Fuck me, Simon, fuck me!” she squealed, then began to shout, “Cum, Simon, cum into me, cum now, now, now...”

Simon could refrain no longer, and gave a final deep, deep crash into her, the head of his cock kissing her cervix, then pumping pulse after pulse of cum inside her. They clamped their bodies tightly together as he emptied himself into her, and rocked sensuously against each other, rolling side to side on the hard floor.

Slowly, their tremors subsided and their bodies melted together, as their breathing returned to normality.

Simon lay there, softening inside her, while they talked.

Ramona said, “That was just fantastic! It couldn't have been more different from my first experience. I just wish it had been you who had taken my virginity, Simon! I felt so FULL of your cock, banging inside me, and now I feel so FULL of your cum. I could not possibly be more satisfied than I feel right now!”

Simon relaxed and slipped out of Ramona, allowing a rush of white cum to flow from her pussy, and streak her black thighs.

“Mmmm,” said Simon, “that looks so delicious, Ramona. Just like strawberry and vanilla ice cream melting in an oval black dish. You have such a gorgeous body!”

They were running out of time, though, so they gathered themselves rapidly and dressed to return Ramona to her parents. Simon passed her her next academic assignment for next week's tutorial, and she pocketed it while she kissed him deeply.

“I will have to think about next week's reward,” she grinned, as they left.

The Third Tutorial.

Ramona's work needed some discussion that week, to ensure that she really understood the more difficult issues. That meant even less time was available for her reward on this occasion, but there was a little.

With that in mind, Ramona said, “I would love to see you cum, Simon. I have sucked you off, and you have cum so deep inside me, but I would like to watch your cum shoot out from that magnificent cock of yours. Perhaps it would help me understand something about male anatomy?”

“There is no need to justify it, Ramona,” laughed Simon, “if you would like to do that. It would make me very happy, but I would love to see your beautiful naked body, to help build my excitement to a peak.”

“Of course!” said Ramona, and began to dance in front of Simon. It was the sexiest, most erotic slow striptease he had ever seen, as she swayed sinuously in front of him, removing each item of clothing until only her brief panties remained. Then she turned away from him and bent herself double, easing her panties down to her ankles before stepping out of them. Her firm round ass swayed hypnotically in front of him, and by the time she turned to face him, he was already hard.

“Spectacular!” said Simon, “but I can't compete with that, Ramona; I'm no stripper.”

Instead, he opted for speed and efficiency, and in no time at all, he stood completely naked if front of an equally naked Ramona, whose eyes were fixed upon his erect cock pointing to the sky. She knelt in front of him, and took him in hand, then in both hands, stroking gently but firmly downwards, while she looked up at him.

When she broke eye contact, to study his cock, he was freed to study her firm young breasts and admire their perfect round nipples, already standing proud. That is where his gaze remained, while Ramona stroked him more and more firmly.

She leaned forwards to lick the head of his cock, and swirl some saliva around it, for lubrication. Then she returned to stroking him downwards, always downwards, admiring the way the head seemed to bulge and grow with each stroke. She was closely studying the bulging veins as they became firmer and firmer on the outside of his rock-hard cock, and the swollen head seemed to throb with each heartbeat.

Simon's legs began to tremble, and as one of Ramona's hands slipped down to cushion his balls, she looked up at him again and said, “Are you ready, Simon? Ready to cum for me?”

Simon could not speak, but had to throw his head back and look away. His hips began to rock, forcing his cock even harder, even faster, through Ramona's tightening grip.

A moment later, Simon let out an animal roar, prompting Ramona to take one last firm stroke and then hold Simon's cock tightly at the thick root. She sat back a little, and her eyes widened as she felt his balls tighten to his body.

They widened yet more, when the first spurt of cum shot from the tip of his cock to arc up above her head and fall back into her shiny black hair. The second spurt caused her to squeal when it hit squarely in the middle of her forehead, and as she tipped her head back, his cum dribbled down either side of her nose and over her cheeks. The third and later spurts only reached her chest, and ran down between her breasts, and across her belly, seeking its natural home between her legs.

All this took only moments, but Ramona was squirming on the floor in front of him. She seemed breathless with excitement as she milked the final drops of cum from Simon's softening cock, and squeezed his balls gently, to make sure she got every drop. She licked the final drops from him and tasted them again—so salty!

Simon needed to sit now, and took the opportunity to admire the shapely black body kneeling in front of him, now splashed with streaks of white cum from her forehead to her pussy. Rivulets of it had coursed downwards, and when she finally released her grip on his cock, her hands moved to smear his cum over her breasts and belly.

“I'm told it's good for the skin!” she smiled, “It certainly feels full of goodness!”

Simon sighed, and said, “What a mess! We need to get you home soon, Ramona, so we had better clean up quickly and get going.”

They both retreated to the shower for a quick hose down. Simon wished they could have taken a more leisurely approach, but time was pressing.

As they walked back to Ramona's home, Simon handed her her next assignment and suggested that they should refrain from 'rewards' on the next occasion. He wondered whether Ramona should divert her sexual energies into her work, because her final exams were approaching very soon now.

She understood what he meant and agreed that they should try to hold themselves back until the exams were over; it was only a couple of weeks after all!

In return, Simon suggested that if she performed well at the exams, they might try to arrange an overnight stay, to catch up on her outstanding rewards. That seemed to please and reassure Ramona, who thought she could persuade her parents to allow a 'sleepover' at a friend's house if the exams went well. She could arrange for her friend to cover for her, in return for a similar favour being returned sometime later.

So that became their plan, and Simon left her at her doorstep with her next assignment to be completed. It was the last one before her exams.

The Fourth Tutorial.

They had decided to refrain from any rewards at this, the final tutorial before the exams, so that all of Ramona's energies could be focused on her revision.

They managed to spend over an hour together almost without touching, and talking only about her academic work and the upcoming exams. Simon went over all the key points of revision, and they speculated about the questions that might be asked, and discussed how Ramona would best answer each one.

When they concluded, Ramona seemed to be feeling distinctly edgy, fiddling nervously with her hands and crossing and uncrossing her legs constantly. She was obviously nervous about her exams, but it was more than that, Simon thought.

He asked her how she was feeling, and she admitted that she was finding it difficult to refrain from any mention, let alone any act, of sex. She understood that the idea was to focus her on the exams ahead, but in fact, she was finding it more of a distraction. She had been fantasising about sex with Simon for the last few days, and masturbation hadn't seemed to resolve the issue.

Simon understood completely, and admitted that he might have been wrong to suggest that they should refrain, but now time had run out and he needed to walk her home to her parent's home at the agreed time.

They set off, and Ramona hugged him in the darkness as they walked. As they got closer, Ramona became increasingly agitated, saying she really didn't think she would be able to concentrate on her exams, because she would be so preoccupied with thoughts of fucking him.

All this was arousing Simon too. He stopped and faced her saying, “If I fuck you now, here and now, will you be able to take your exams? They start tomorrow, don't they, and spread over the week ahead, so this is absolutely our last chance!”

Ramona faced him and melted into his arms, saying, “Fuck me, Simon. Fuck me here and now, and I promise I will do my very best in the exams!”

There seemed to be no one around, though they were quite close to Ramona's home now, but there was a small grassy area off to one side, with a little group of huge trees providing cover only a few steps away.

Simon led Ramona across the grass to the nearest and biggest of the trees, and pressed her back against the trunk; he pressed himself against her, and she could feel his cock hard against her belly as he squashed her against the tree trunk.

“O God, Simon,” she gasped, “will you fuck me here? Please!? I promise I'll do well in my exams if you will!”

Simon bent and reached up under Ramona's skirt, pulling it up around her waist. He cupped her ass in his hands and lifted her bodily, so that she could wrap her legs around his waist, while her arms moved over his shoulders, to wrap tightly around the back of his neck. She was now sandwiched between Simon's body and the rough bark of the tree trunk, clinging to his body like a limpet, with her arms and legs.

He reached between her legs to grasp the crotch of her panties and pull them roughly aside—there was a tearing sound as they ripped, giving his hand access to her dripping pussy. Then he unbuttoned himself and somehow pulled his hard cock out into the cold night air—that was stimulating!

Ramona also felt the cold air around her wet pussy and squeaked with the sharpness of the feelings.

Simon lifted her a little, to allow his rigid cock to find its way between her legs; it needed no further guidance to find its way to her welcoming pussy, and he lowered her slowly onto himself, until she was fully impaled. They both sighed with deep satisfaction as her clit rested on the root of his thick cock, and the swollen head pressed firmly against her cervix.

They stayed still like this for a moment, before Ramona began to wriggle her hips against him while remaining fully impaled upon him. Simon looked down and kissed her deeply; their mouths opened and their tongues engaged with each other as their kisses became ever more passionate and their bodies squirmed against each other.

She pulled away and said, “Simon, if you fuck me now, I will last until after the exams, then we can fuck all night!”

Simon supported her ass with his hands and lifted her a little, pressing her back hard against the rough bark of the old tree to suspend her there. He began to move his hips now, thrusting his rigid cock steadily in and out of her, while she gasped with every stroke.

He could feel her body begin to respond, her hips countering the movements of his own, to emphasise the clash at full depth, and she groaned louder and louder. But suddenly they both froze still and silent, as they heard a voice in the darkness, saying, “Hello, is there someone there? Are you OK?”

They could hear the rustling of leaves as someone seemed to approach, muttering to themselves. They almost stopped breathing, but Ramona could feel Simon's cock throbbing inside her, in urgent need of relief, and she gripped him with her vaginal muscles. “Wait,” she whispered, “just wait a minute, and they will go away! Then you can explode inside me!”

Simon heard a female voice say, “I don't think there's anyone there, Bill. Come back to the house now. Ramona will be home soon, I think.” It was Ramona's Mom calling Bill! Realising this, Simon's erection almost failed instantly, but Ramona gripped him tightly again, and he recovered himself as he heard her parents moving away.

He looked down into her startled face and kissed her once more, before they resumed fucking. Their movements became more and more rapid, more and more urgent, and their kisses more and more passionate. Ramona squeaked in pain as her back rubbed against the hard rough bark of the tree, but the pain was worth the pleasure she felt welling up from her clit to fill her entire body with trembling warmth.

Simon contributed to that feeling by pumping his hot cum deep inside her, while they both held still. They felt it trickle from her, over his balls and down her swollen pussy lips, and when he released her to stand on her own two feet again, it ran down her inner thighs to her knees.

They composed themselves and adjusted their clothing to hide any sign of illicit behaviour, and stood facing each other for a moment.

“Thank you so much, Simon, “ said Ramona, “I will blast through these exams now, and when I pass everything with flying colours, we can fuck all night!”

They continued the very short distance to Ramona's house, where her parents were already waiting at the open door, with the porch light shining brightly.

“Ah,” said Bill, “we were wondering when you would get back. We heard some suspicious noises nearby, but it seems to have been nothing; you can't be too careful in the dark nowadays, so thank you for walking Ramona home, Simon. Did your lessons go well?”

Ramona looked a little sheepish, but Simon simply said, “Yes, Bill. Ramona has performed excellently, and I'm sure she'll do well in the exams. Be sure to let me know the results as soon as you hear them.”

Bill nodded, “Of course, Simon,” and Ramona smiled demurely, saying, “I'll tell you as soon as I know, Simon.” Then they closed the door behind them leaving Simon to walk back home, thinking that they had escaped by the skin of their teeth!

The evening of Ramona's sleepover.

With all of the academic preparation, and the personal motivation burning deep inside her, Ramona performed beyond all expectations in her exams—she only had to wait a day or so for the results, and both she and her parents were delighted when she passed with distinction. Bill immediately told Simon, and invited him to a celebratory dinner in honour of Ramona, and of course, of his tuition.

“It will have to be next weekend, Simon, if that's OK with you,” said Bill, “Ramona has arranged a celebration of her own at a sleepover with one of her girlfriends on the other side of town. We think she deserves it, but we've told her not to go too wild!”

Simon could only accept Bill's offer, and try to hide his guilty conscience, knowing that Ramona would actually be spending her sleepover with him, and probably would be going wild! She had already called Simon to say that she would be joining him on Saturday through Sunday, and her Mom had approved her celebration. She might not have approved if she had known the full truth!

Ramona arrived by cab at Simon's house looking stunningly glamorous, in a black sequined dress just above the knee, black silk stockings and ruby red high heels to match her crimson lips and nails. Her black hair curled down to her shoulders, and her black skin glistened with health, and no doubt with fashionable moisturiser too.

As soon as she entered, she rushed over to hug him tight, repeating, “Thank you, Simon, thank you,” over and over again.

He said that it was her who had passed the exams, not him! He may have helped, but it was all down to her own efforts, really.

She understood that, but said he had provided her with the motivation as well as the knowledge, and she would be grateful forever. From the beaming smile on her face, it seemed she wanted to show her gratitude straight away.

She held his hands and stepped back, saying, “I have a present for you, Simon! Would you like to unwrap it straight away?” and she guided his hands to her hips. It was very clear what she meant when she turned her back on him and reached around to unhook the dress at the top and tug it open slightly, to start the zipper in motion downwards.

She looked over her shoulder at him and said, “Do you need any more help, Simon?”

Of course he did not.

He pressed himself against her back and rested his chin on her shoulder, breathing hot breath into her ear, then flicking her earlobe with his tongue, before sucking it between his lips and teasing it back and forth. She felt herself turning to jelly as one hand tugged her zipper slowly down her back, all the way to her ass.

He parted the dress over her shoulders, and it fell down to her hips. She wriggled and it easily fell to the ground, where she stepped out of it. He wrapped his arms around her and pressed his hard cock against her ass, saying, “I see there are several layers of wrapping, Ramona! I will take my time, if you can wait.”

She bit her lip. She really wanted him to hurry, but at the same time, she wanted him to be slow. It was an exasperating contradiction, but provoked a trembling excitement within her.

Beneath her glittering dress, a tightly laced corset was revealed, emphasising her hourglass shape. It was made in the deepest purple satin trimmed with black lace, between her purple bra and panty set, above black hold-up silk stockings. When he unhooked her, he peered over her shoulder as her pronounced cleavage slowly relaxed into her lacy bra, and he set the corset aside.

They were both delighting in the slow revelation of the body she wanted to give to him.

He turned her to face him and pulled her close, while he unhooked her bra and cast it aside. He weighed her beautiful breasts in his hands and teased her erect nipples with his thumbs. His hands slid down her sides, feeling her natural hourglass shape, then slid round to her firm ass and pulled her hard against his own body.

She looked up at him and said, “How would you like to fuck me, Simon?”

He admitted that his favourite position was 'doggie style,' as he found it gave him the very deepest penetration possible. Ramona had never experienced this. The missionary position with Simon had been her first real experience, and she found it difficult to believe that even deeper penetration could be possible, but she was very willing to find out, and allowed Simon to guide her.

She now wore only the briefest deep purple panties and black hold-up stockings. Simon led her to sit and took each leg in turn, raising it up to rest on his shoulder while he slowly rolled her stocking down and peeled it from her foot. Then he made her stand while he kneeled before her, and rolled her panties over her hips and down to the floor. As he did so, he took the opportunity to plant a firm kiss on her shining black pubic mound, and briefly flick his tongue between her legs. She squealed when his tongue stroked her erect clit as it passed; so he did it again!

Now he took the wholly naked Ramona by the hand and led her to his bedroom. He wanted her first experience of being fucked from behind to be a fulfilling one.

She was a little uncertain, and let Simon guide her to kneel on the end of the bed with her feet sticking out, then to fall forwards onto all fours. He stood between her legs, and she could feel the full hard length of his cock press between the ample cheeks of her ass. He squeezed them together around himself and slid slowly back and forth, prompting her pussy to drip in anticipation. She was already wet and open, but now she was really ready for action, and her moans and groans excited Simon beyond belief! He felt bigger and harder than ever.

She pressed herself back against him and he forced the head of his cock down, to lodge just inside her pussy. Looking down, he saw the exciting sight of his long white cock poised to enter the bright pink gash of Ramona's pussy, between her swollen black lips, as she angled her ample ass to accept him.

He put his hands on her ass cheeks and steadily pressed his cock into her, closely watching each hard inch as it disappeared inside her softness. As he slowly withdrew again, he marveled at the slick, shiny coating his cock had acquired inside Ramona, preparing him to thrust more energetically into her.

He leaned forward and pressed her shoulders down to the bed, her face turned to one side, breathing heavily. He began to thrust harder, faster and deeper into her while she tried to press back against him, when each thrust moved her forward. She was squealing with each hit of her cervix as he pounded into her again and again. Her ass shook with the impact each time, cushioning the strike a little.

Simon reached around her hips to tease her clit with his long fingers while he continued his hard thrusts into her, and she responded with screams of pleasure, and perhaps a little pain. Her screams became louder and her hips ground more quickly against him, until he felt her pussy spasm around his cock and she let out one very loud, long scream.

He gave one final deep thrust into her and stopped with the thick root stretching her to her widest, while he pumped his cum deep into her and her cunt milked him, as one hand squeezed his balls. He stayed motionless for minutes, it seemed, while she gently rocked her hips to draw every last drop from him.

He folded forwards over the soft black cushion of her ass, and kissed her between the shoulder blades, while his hands reached around to cup her breasts. Then he withdrew, and they both rolled alongside each other. Ramona glowed with pleasure, and she smiled a 'Thank you' to Simon before they fell fast asleep in each other's arms.

It was late when they both woke, and Simon led Ramona to the shower, for a more leisurely clean-up than they had had before. They sprayed and washed each other meticulously, in every nook and cranny, and Simon took great delight in soaping Ramona's breasts. He played with her soapy nipples and enjoyed the sight of white foam flowing over her glistening black body. She enjoyed soaping his cock clean, and so did he.

When he asked how she felt about her first experience of 'doggie' sex, she said that she had felt how much more deeply Simon had thrust into her, and in fact, she felt a little bruised and battered by the deepest strokes. She felt she needed a little more recovery time before they fucked again.

Simon was apologetic, but she laughed and said, “Simon, I loved it! But it's not something I could do every time, unless you could restrain your deepest, hardest thrusts a little.”

While he gently dried her body with fluffy white towels, he said that she should be more in control next time. Instead of him fucking her, she should fuck him. They headed for bed, wrapped in towels, but only to sleep for the night. In the morning, Simon would introduce her to the 'cowgirl' position which would let her have control.

The morning of Ramona's sleepover.

When they did wake, Simon already had a natural hard-on which Ramona discovered almost instantly, and she was delighted, because they didn't have much time. She was supposed to be on a sleepover at a girlfriend's house, so she would have to get home by lunchtime. That meant booking a cab to take her the short distance home, because she was supposedly arriving from her friend's house on the other side of town.

“You were going to teach me a different way to fuck?” she said, “One that would put me more in control?”

“I would love to give you free rein in the cowgirl position!” said Simon, and rolled onto his back, throwing the bed covers aside. His cock was proudly waiting, and Ramona took him in hand, pointing it vertically to the ceiling, and marveling at the throbbing veins and swollen head, and at the length and thickness of it. She wondered how she had accommodated it all last night, but then recalled that she had felt rather bruised by the clashes against her cervix when Simon was in the final throes of passionate thrusting from behind her.

Her first instinct (that is, after stroking him firmly a couple of times) was to drop her head and take him into her mouth, but Simon stopped her doing so. He asked her to straddle him, across his belly, and said, “You just need to take me inside you, Ramona, and use me for your own pleasure, as fast or slow as you like, and as hard or gently as you like. Whatever you do, I assure you that I will be enjoying it! If you feel a climax building, and want to delay it, just pause awhile. I think I will know when you are ready for me to cum inside you again.”

Ramona understood, and reached between her legs to position Simon's cock. To begin with, she slid her spread pussy lips up and down the length of his cock, coating him in the juices which flowed from her. Then she reached down to force his cock upwards and locate the head in her vaginal entrance.

Moving backwards against him, she looked down to see the full length poised to enter her, and she sighed deeply, “What a big white cock you have, Simon! I want all of it inside me.”

Slowly, she pressed down on him and groaned as inch after inch slid inside her. When she reached the base, she was stretched open to her limits, she thought. She sat on him now, fully embedded inside her, and rocked her hips to and fro, finding that she could stimulate her clit against his body, and explore the inner depths of her cunt with the swollen head, rubbing it against her vaginal walls.

She realised that she really did have complete control of the situation and began to use it to maximise her own pleasure, rocking and rolling her hips, sliding up and down his cock, playing with her own clit, until she was ready to enter the final straight.

She pressed her hands down on Simon's chest, to give herself the leverage to ride him, and tensed her ass to tighten her thighs as they lifted and fell. She looked down at him and said, “I'm going to fuck YOU now, Simon! Don't cum until I say you can.”

With that, she began to rise and fall on Simon's cock, all the while maintaining eye contact with him. She told him to play with her breasts as they bounced in front of him and he was very happy to comply, taking the opportunity to squeeze, pinch and pull on her nipples while she rode him.

Her thighs gripped him now and she lowered her body over his, so that her hanging breasts swept back and forth, up and down his chest. Her movements were getting faster and faster, and Simon could feel her cunt starting to tense around him, as she forced him harder and deeper inside herself.

He could sense that she was about to cum, before she said anything, but then she blurted out, “Cum, Simon; cum, cum, cum now!” She rode him fiercely for several more strokes, before she rammed down hard on him and stopped suddenly. She sat on him and trembled inside, her belly and thighs tremored, and her breasts shook with sexual release, and Simon duly delivered his cum, in pulse after pulse, each one felt throughout her body.

She collapsed on him and it was some time before either of them stirred. When she did roll aside, she took his face in her hands and kissed him deeply. “Thank you so much, Simon,” she said, “You have taught me so much over recent weeks, I feel like a different person altogether. I think I owe you more than you can ever understand.”

Simon said that he was tremendously flattered, but of course, he had enjoyed their times together too! He thought she was a beautiful and sensual creature, and truly her Mother's daughter.

Now though, time was passing, and there was only the chance for yet another shower. It had to be quick this time, as the cab was already booked, and the doorbell could ring at any moment.

When it did, they were waiting, with arms around each other, to say goodbye for now. They did not know what might become of their relationship, but the next—and perhaps final—hurdle was for them to meet again at her parent's house, for their own 'Thank You ' celebration of Ramona's success and of Simon's help in that.

Epilogue.

The celebration with Bill and Ramona's Mom went by largely in a blur, for both Simon and Ramona.

Her parents were clearly delighted with Ramona, and very thankful for Simon's help in getting her over the hurdle of the exams, which she had passed with distinction.

Everybody was clearly very happy, but Simon and Ramona were perhaps a little withdrawn and uncharacteristically quiet. Simon did not flirt with Ramona's Mom at all, perhaps because the images in his mind of Ramona, in the full throes of sexual ecstasy, were too present, too recent.

At the end of the evening, however, her Mom took Simon aside, just before he left, and said, “I don't know how you did it, Simon, but you seem to have cast some sort of magic spell over Ramona! It's great to see how far she has come in such a short time. My little girl has been unrecognisable since her exams.”

Simon felt himself blushing as he looked her in the eye—she was SO like Ramona!—and said, “She isn't a little girl any more, she's a young woman, and ready to face the world. You should be very proud of her.”

Her Mom leaned forward and kissed Simon on the cheek as he left, and he felt a thrill run through his body.

When he walked home in the darkness, he could hear Diana Ross and the Supremes playing through his head. He tried to remember all the lyrics of 'Baby Love,' but they kept getting confused with the lyrics of 'Where did our love go?' ''

No one knows the answer.
