Olivia took a deep breath, shook herself a little to try to calm the nervous trembling that quivered inside her, and pressed the door bell. She waited only a minute, even less, and the door opened.

"Oh hi Olivia," the man at the door said. It was her next door neighbour in the small, quiet street. A bit of a mystery man, though well-liked by everyone, forty-ish, single, rarely said much at all about his private life, and all the neighbours respected that. No-one was even sure just what he did for a living, but they all knew he had plenty of money, was generous with friendly loans on many occasions, was very, very intelligent, and held great parties. His name was David and over the last few years he and Olivia had become good friends. She was a straight-A student at her university, doing an advanced course in physics, and was recognized by the uni as a star student with a huge future. Olivia was an extremely intelligent girl, and she allowed quite readily that a proportion of her academic success was due to the help that David gave her. Not that he ever actually did her work for her, she would not have dreamed of asking that, and he would have refused if she had. But he was brilliant at explaining things, at asking the right questions, the sort of questioning that slowly guided the learner to the solutions.

David looked at her now, as he always did, seeing a very pretty young woman, dark blonde, almost brown hair, slim. Despite her beauty, of which she did not seem to be aware, Olivia never seemed to have a regular boyfriend. She was a loner, living with her mother next door, totally committed to her academic career. Despite his respect and liking for her, as usual David could not stop himself from admiring her looks, her slim legs that emerged so prettily from beneath the mid-thigh length denim skirt, the smallish (probably a 32 b, he had decided a fair while ago) breasts, today concealed under a grey T-shirt with a heavy-metal rose and heart type motif on the front. He was surprised to discern that she did not appear to be wearing a bra, and was angry at himself for noticing.

"Hi David," Olivia chirped brightly, watching his eyes in their quick tour of her body. She had noticed a while ago that David admired her, especially at the pool parties when all she was wearing was the modest blue bikini she liked so much. She liked that he admired her, liked him and trusted him, and was often annoyed that he was too well-mannered, or too afraid, or too conscious of the difference in their ages, to have ever done any more than look at her admiringly. There had been several parties when she would not have said no if he had suggested anything more than the involved scientific discussions they often indulged in, and there had been one party when she had thought she had done a lot to encourage him. But perhaps he had just dismissed it as her having had too much to drink.

That would change today, this afternoon, she hoped, as her physical loneliness, and an overwhelming curiosity about something, had given her the courage to be here now, standing waiting for him to ask her in.

David saw that over her shoulder, Olivia had the bag which usually contained her files and books, whatever was relevant to the problem she was trying to solve. Nothing 'untoward' had ever happened between them, and with a twinge in his belly he had to concede that nothing ever would.

"Come in, Olivia, it's nice to see you again," he said, standing back to let her through the door, watching her cute bum wiggle under the skirt as she walked automatically to the table where they usually sat. He had noticed some sort of tension in her face. "You look like you have a big problem that needs solving."

"A very big problem," Olivia said softly, annoyed at the slight tremble in her voice. "An experiment-a difficult experiment-that I just have to do, and I know you are the only person who can help me with it. I just hope you won't say no."

"Now why would I say no," David laughed. He went to the fridge and took out a jug of lemon squash, some ice, made two long drinks of it and brought them over to the table. Olivia wished he had offered her something stronger, but no, she needed to keep her mind clear for this.

"So," David continued, "what's this problem that has put that frown on your face?" He lit a cigarette, offered Olivia one, was puzzled that her fingers trembled slightly as she accepted it. She was normally very confident about everything.

"Well, it's...there's something I need to find out," and Olivia became very annoyed with herself that she was struggling to find the words. Ever since she had decided on this, a few days ago, she had rehearsed over and over in her mind how she would make the suggestion to David. Ever since that enlightening conversation with several of the young women who were as close as she came to having best friends. It had been at a bar, and they were all a little drunk, and Olivia had been amazed and fascinated by some of the admissions the others had made about their sexual activities.

For herself, Olivia rarely bothered with it. Occasionally, if the mood was right, and the guy was nice, she went along with it all and normally it was all ok, though she had never experienced the mind-blowing bells, stars, explosions, however it was worded, that sex was apparently meant to be if it was done 'right'. Often she wondered if those sorts of reactions were in fact reality, or just made up stuff in novels and movies.

Anyway, she had gathered from the conversation that there were experiences she had so far missed out on, Mandy's hand on her thigh several times had convinced her that there was an opportunity to experiment that way, but it was another sort of activity that had intrigued her more, and she could only think of David as the person who could help her explore it. But she had to admit to herself that she might also be running the huge risk of earning his anger, or even contempt. All she had to go on was the way she often caught him looking at her, and her belief that most men would never say no. But also at the back of her mind was the certain knowledge that David was not most men.

She had spent hours the evening before researching on the internet everything she felt she should know about it, had even taken notes-typical me, she had laughed derisively at herself-and now it was just a matter of having the courage to ask him.

"It's not...the usual sort of thing I ask you..." and her trepidation was obvious. David was now very intrigued. They had a good relationship, friends, perhaps mentor and student, nothing formal, no money ever changed hands. So why was she so nervous about this.

"Well, you know I am always here to help you out," David tried to reassure her. "It's so wonderful seeing you doing so well in your studies."

"This isn't really related to them," Olivia almost whispered, and tried to laugh to calm herself. "It's more a personal thing." Even more intrigued now, David decided that she must be wanting boyfriend advice. He encouraged her with a smile.

"Well I hope whatever it is, that I can help Olivia, you know that," he said, and he wanted to pat her hand as her fingers drummed softly and insistently on the table. But he didn't.

"Ok...well...ok," and Olivia took a deep breath again, and decided there was no other way. "It's...some friends of mine were talking the other night...some things they said...made me curious...I really need to know...sort of like research you know..." she laughed to cover her flusteredness, "I really need to know what it's like to..." another deep breath and nervous, soft laugh, " to be fucked in the bum." And she looked deep at his eyes to gauge his reaction, "and I was hoping you would...you know..." Very flustered now, she trailed off, happy though that his reaction was not one of shock or amazement. His eyes said that he liked what she had proposed.

For a few moments there was silence. David was in fact amazed, stunned, at what she had said. Could it be that all those fruitless nights of fantasizing over what it would be like to spend the night in bed with her were about to become reality? Not that he had ever imagined that she would suggest this particular activity, but even so.

Olivia rushed on, not wanting any more silence, still afraid he would laugh at her or something.

"I've done a lot of research," she was scrabbling around in her bag, pulling out a file, and a small tube, "I've prepared myself...you know...the sites suggested some things...I have this...they said it would be a good idea," and she pushed the tube of lubricant to the middle of the table, and opened the file, "I even made up a list of questions that I want to know the answers to...need to know..."and again she trailed off, her voice very quiet now, she looked down at her knees, not wanting to meet his eyes, in her mind begging him to say something.

David felt sure now that there was no harm at all in touching her. He reached over the table and took her hand. His mind raced in its search for the right words, to tell her he loved the idea and wanted to help her, but at the same time to be careful not to appear insensitively over-eager to see her naked, to touch her, to fuck her, even though these were things he was very eager to do, and had been for several years now.

"I think that would be a great experiment for us to do together," he said softly, annoyed at the thickness that came into his voice, and squirmed a little to placate the erection that had sprung to life as she had been talking.

"Really?" Olivia asked, the relief was enormous, she felt a flood of warmth rush through her, and an easing of tension in her body such as, up till now, she had only ever felt after masturbating. And even more pleasurable was the growing in her of a new kind of tension, a much more pleasant kind, the thrill of anticipation.

The edginess that had been in the air just now had dissipated, and again they were a pair of enquiring minds, at the beginning of a new adventure into learning something as yet unknown. They lit more cigarettes. Her voice was calm now, though her body wasn't. Deep in her belly she felt tingling and a twitching. A delicious twitching and tingling.

"David...may I ask...do you have any...um...experience...in this sort of research?" and she laughed-she had a beautiful laugh, he had always thought that-she laughed at how she had worded her inquiry.

"Yes I do," and David laughed with her. They were both totally relaxed now, and both totally enjoying these quiet moments in anticipation of the intimacy they were about to share.

"Then," and Olivia put out her cigarette, she didn't normally have two so close together, and she wanted to keep her mind completely clear, to appreciate fully this new experience.

David looked with amusement at the list of questions typed on the one sheet of paper in the file. It was so like the scholarly young woman she was, there were a lot of questions, and they were arranged in groups and sub-groups. He smiled to himself that it would be just like her to want to pause frequently during their 'experiment' to make notes. He was sure he wouldn't mind that.

There was an air of lightheartedness now, now that what was going to happen had been assigned a name, it was an experiment, and they had done a lot of those together.

Olivia rose from her seat, and walked around the table and sat herself on David's lap. It was the first time their bodies had ever made any sort of contact, and it was special to both of them. Feeling much more relaxed now, and cheeky, she wiggled her arse on his lap, felt his erection through their clothing, liked it.

"Well, it seems your equipment is prepared for our experiment," and she giggled and wanted to kiss him. David laughed with her, fighting against the urge to push the bulge in his jeans back at her bum. He wondered if kissing her would be consistent with the experiment. Olivia put an arm around his shoulder, and she smelt beautiful, a light, seductive perfume, he inhaled the scent of her deeply. The way she was sitting with her arm across his shoulder he could see into the short sleeve of her t-shirt, and he looked closely for a few seconds at the sexiness of her armpit, smooth and white, with that intriguing mound in it, a reflection of another mound he knew he would be seeing soon. This thought made his cock twitch, she must have felt it because she giggled, and wriggled her bum on it again, and then she went on, "And like I said, I've prepared my um...equipment," and they both laughed again.

There was a brief pause now, who would bring it up first, the moving to the bedroom? Olivia assumed that would be where they would go. She knew he was too much of a gentleman to just bend her over the table and 'do it', though that was an exciting prospect too. Yet another thrill of heat tingled deep through her belly, and down between her thighs.

"You know," David said a little nervously, "in this sort of um...experiment, it will be a big help to you if you are very aroused." He hoped he hadn't sounded too practical, too eager.

" I knew you would be the best partner for my experiment," she replied, very excitedly. "Oh yes, I know that. My research told me that, while there might be a fair bit of...um, while it be uncomfortable, it isn't so bad if I'm um...as you said, aroused," and with her tone, matching his, it could have been that they were discussing theories for a new method for splitting the atom. "That's why I decided to ask you to help me with this research. Because I know you believe so strongly in doing things um..." she couldn't find the word, she didn't want to say methodical, she was genuinely interested in finding out what anal sex was like, but she didn't want it to be too impersonal, too disinterested. "Thorough," she went on. It would have to do, though it still wasn't really the word she was looking for either. She definitely wanted this to be fun, and the tingling deep down in her belly was telling her she was expecting more than that too. David felt her body tremble on his lap, and he looked at her, and she looked back at him, and their eyes made an important new understanding, and she bent her head and put her lips on his.

David's arm moved from the table, and his hand rested on Olivia's leg, just above her knee. Her skin was warm and smooth, and his hand slid up her thigh, slowly, stopping just under the hem of her skirt, then back to her knee again. In response Olivia pressed her tongue at his lips, they opened, and their tongues tangled gently, exploring, kissing softly, each exploring the scent and taste of the other's mouth. Olivia took a deep breath, waited for David's hand to venture further, wanting it too, loving the feel of it on the firm smooth skin of her leg. She squirmed a little, David understood the signal, his hand went under Olivia's skirt, and his fingertips stroked gently at the softer sensitive skin at the top of her inner thigh. Her tongue went deeper into his mouth, and she pressed her arse down hard on the bulge in his jeans. The sensation of his fingers on her thigh, the knowing how close they were to her delicate entrances, was wonderful, and she was so glad she had had the courage to ask him to help her with this research.

The kiss broke off.

"Shall we move into the laboratory," David asked her with a smile, and she laughed very softly, and stood up, missing the feel of his hand on her thigh, trembling with the anticipation of what was coming. David stood and took her hand.

"Shall we bring the file with the focus questions?" he asked, and they both laughed happily at the ridiculousness of it.

"No," she laughed, "we both have good memories. We can make our notes afterwards." David led her to his bedroom.

It was a large room, with French windows opening out on to the huge patio area which surrounded his pool. Olivia had swam in that many times, and told herself that today, after the experiment, she would ask if he would mind her swimming naked in it, something she had long wanted to do. Of course, she had never been in his bedroom before, and her belly tingled at the awareness of why she was there now. She slipped her sandals off and sat on the bed.

David had been barefoot anyway, and he knelt up on the bed, behind Olivia. She breathed deeply as she waited, expectantly. In his jeans, David's cock twitched and jumped, he felt little shards of heat racing through his belly, through his cock. This beautiful young woman was waiting for him to undress her, to touch her, and to be very intimate with her. It was taking all his years of experience, with many women, and all the power of his innate good manners and considerateness, to remind him to keep it all slow and gentle.

She turned her head to his, their lips met again, and his tongue slowly slid around inside her mouth, taking in all the sweetness of her breath, and the warmth of its excitement. As he kissed her, he moved his hands to her hips, his fingers closed gently on the hem of her t-shirt, and he lifted it up, slowly, over her belly, the edges of his hands making contact with the smooth warm skin of her belly for the first time, it was electrifying, and Olivia felt that way too, her body trembled, her tongue pressed at his, as he lifted the t-shirt over her breasts.

David looked down, his tongue still playing with Olivia's, and his mind sighed at the sight of her breasts for the first time. They were beautiful, firm and upright, pushing out from her chest, the nipples that beautiful reddish-tinted brownish colour, erect from her anticipation. Olivia broke off the kiss, and watched his eyes as they took in the beauty of her breasts. His hands moved a little, and cupped underneath them, and for a second she tilted her head back and closed her eyes. The softly tender way his hands were just cupping under her breasts, his thumbs very gently stroking at the sensitive skin, reassured her that this was going to be very different from the mashing they were used to from the young men she had been with up till now.

David moved his thumbs to Olivia's nipples, so hard they felt, and began making firm little circles over them, around and around. At the first touch, Olivia had gasped, and now her breathing change, and she felt a moisture between her thighs, and she stroked his hair as his thumbs rubbed little circles into her nipples, and the tips of his fingers scratched so softly at the delicate skin on the undersides of her breasts.

"Mmm," she was moaning softly. With another kiss to her lips, David lifted Olivia's t-shirt over her head, and dropped it on to the bed. His hands closed over her breasts again, and he let the skin of his palms savour the feel of them. Olivia's tongue flicked at his lips. Arousal was not going to be a problem, she could feel the building in her belly, soft and just hinting at the moment, hinting that it was getting stronger, and would only get better and better.

She knelt up on the bed now, and smiled at him, her chest pushed out a little, encouraging, and David bent his head and his tongue flicked first at one nipple, then the other. Then his lips closed over her right nipple, and he tugged softly at it, his tongue licking at the tip of her nipple, sensing the little split in it, his mouth moved, his lips closed around more of her breast, tasting the beautiful skin, his nose inhaled deeply the scent of the skin of her breast. Olivia sighed softly, her hand pressed down on his head, she bent and kissed his hair, little kisses, his hair smelt recently shampooed, already there was a new tenderness between them, she sighed softly over and over, her mind and body reacting to the sensations of his lips and mouth tugging so amazingly gently at her breast, it was if he wanted to take all of it into his mouth, she moaned again, kissing his hair. David's hand moved from her hip, down under her skirt, his fingertips traced along the inside of her thigh, she gasped again as his thumb brushed at her panties, brushed delicately at the fabric, just where her entrance was covered by the soft fabric, his thumb pressed a little, she arched her back, pressing her breast at his mouth, as his fingers went in the leg of her panties, pressed gently in, and Olivia gasped again when one of his fingers found her clit, started rubbing on it, she inhaled deeply at this first touch of him so intimate.
