Billy had been working in the local department store for 5 years after leaving school. He started at the bottom, sweeping floors, but his pleasant, easy manner with the public soon got him noticed by management. Soon he was promoted to junior manager of the footwear department. He soon found that women love shoes, and developed a good rapport with many of his female clients, selling a lot of expensive high end shoes to wealthy women. His 6"1' lean muscular frame and boyish good looks certainly helped and also meant his job was a good way to meet women from a romantic point of view. However, he quickly learned that mixing business and pleasure was a bad idea, as the end of a private relationship with a customer could quickly turn into a loss of sales with both that particular woman and all her friends.

In the end Billy decided to keep his interactions with the ladies down to innocent flirting, enough to keep the woman happy and coming back for more shoes, but not enough to lead them on in any way. Unfortunately this led to a rapid downturn in his social life, as the long hours he worked meant he had difficulty meeting women outside of work.

However, things were about to change. One fateful Monday morning Billy was called in to the general manager's office.

"Billy, I have called you in here to congratulate you on the good work you are doing in footwear," the manager said. "Sales have doubled since you have taken over, and we have received many glowing recommendations from happy customers, in particular the female ones."

"Thank you sir, I aim to please," Billy replied cheerfully.

"However I think we have another challenge for you to take on now," the manager continued. "We would like you to move on to the underwear department and see if you can work your magic there. Sales are down quite a lot recently, and we need to make more of that area of the business."

"I don't really know much about underwear sir," Billy said nervously. "Perhaps a woman would be better in that job, I don't think our female customers would be very happy with a man giving them advice on underwear."

"Nonsense son," the manager replied. "Out lady customers seem happier with you than any of our female staff, and you will be the manager of the department. It is not as if you will be measuring their bra sizes, you will have female staff for that."

"Well if you think it will work sir," Billy replied, still not completely comfortable with the idea.

"Excellent, you can start today," the manager said.

So began Billy's career in the underwear department. It turned out the manager was correct, Billy quickly found his feet and the department sales began to rise rapidly. The main problem Billy noted was the previous range of underwear was very plain and unattractive. While there was always a place for that type of thing, Billy discovered that most women liked at least some sexy underwear for "special occasions" as well as their everyday garments. He began to stock sexier, more revealing ranges of both underwear and swimwear, while at the same time publicising these more exotic garments heavily. Soon the sales of normal everyday underwear had doubled, and the sexier ranges were selling out regularly. He also started promoting men's underwear in the same way, as he found many of the women bought sexy boxers even thongs for their boyfriends and husbands while choosing their own underwear.

Billy soon found his new job even more enjoyable. As a manager, his direct contact with the customers was reduced. However he was still on the shop floor for several hours a day, and on most days his opinion was sought on how a particular undergarment looked, from a man's point of view. While on these occasions he enjoyed looking at some very lovely ladies in skimpy underwear, he always maintained his rule of not dating customers, and made sure a female member of staff was with him in the changing rooms with customers.

One Thursday morning however, things were going to change. Billy arrived to find out that both his female staff members were off ill and he was alone in the department. "OK," he thought. "Thursdays are not normally too busy, I can serve the customers myself, and if any fitting is required I will just have to ask the customer to come back another day."

Most of the day went smoothly, right up until 5.30 when the shop was about to shut. Billy was alone at the till when a young woman walked into the department. She approached the till and smiled shyly.

"I was wondering if you could help me choose some underwear," She said, obviously nervous about speaking to a man about this.

"Certainly," Billy said, "I hope you don't mind but I have no female staff today so I will have to help you myself. Are you OK with that?"

"I suppose so," she said, again very nervously. "My name is Laura."

Billy looked her over quickly to get an idea on what would be best for her figure. It was quite difficult as she wore a heavy coat, wool sweater and trousers. She was quite petite at around 5 foot with medium length dark hair, which was tied up. She wore fashionable rimless glassed and very little make up, however her face had a fresh-faced innocence that Billy found very appealing. He was sure he had seen her before.

"Have I served you before?" he asked.

"No, but I was in with Alison a few times."

Now he remembered. Alison was the local beauty queen, currently at college studying law. She was smart, rich and had every local boy lusting after her. She also spent huge amounts of money in the underwear store on sexy underwear. Several times she had indicated to Billy that she would welcome a sexual advance on his part, but he was honestly not interested. He found her beautiful, but shallow, vain and too high maintenance for his tastes. He also had his rule about never dating customers.

Laura was the proverbial "plain friend" that Alison kept around to make herself look even better. Laura worked at the local library and always wore very sensible plain clothes with little make up, as today. If he were being honest Billy would have had to say he had never really noticed her before, Alison always grabbed all the attention. However looking at her now, there was something in her shy smile that he found attractive, and he was surprised he had not noticed her before.

"Is there anything you were looking for in particular?" Billy asked.

Laura smiled nervously again. She had never done anything like this before and it had taken her weeks to work up the courage. She was used to living in Alison's shadow, buying the same unadventurous bras and pants every few months. However recently she had been getting tired of being the plain friend and after turning 21 had decided to do something for herself for once. Now she was standing in front of this gorgeous guy that even Alison had not been able to hook. He looked as if he really wanted to help her as well. She had fancied Billy from afar for as long as she had been coming to the store with Alison. She loved his tall athletic body and infectious smile, as well as his easy way with woman. He was dressed causally in black trousers and an open necked shirt, which made him look less intimidating than if he had been in a suit. Despite herself, Laura felt herself getting more relaxed in his presence, even though there were no female staff present. She decided to press on anyway before she lost her nerve.

"Well... I was thinking about something a bit more adventurous than I would normally wear. I have seen some of the beautiful underwear Alison has, and I think I might like something a bit like that. I don't know if it will really suit me though. I am not anywhere near as pretty as she is."

"That has nothing to do with it," Billy replied. "Sexy underwear is there to make you feel good about yourself, no matter what you look like. I am sure your boyfriend will appreciate it as well."

Laura laughed. "I am afraid I don't have a boyfriend. Alison gets all the boys; I am too plain next to her. Still I think I would feel better about myself if I had something pretty on underneath my clothes."

"Excellent," Billy said. "Let's look at some styles. I am afraid, as there is no female staff we can't take any measurements today. Do you know your size?"

"Yes, I think so. It has been a year or two since I was measured though," She replied.

They both walked over to the changing rooms. Billy beckoned for Laura to go inside.

"It might be useful if I could see what you are wearing just now, to give me an idea on what we are starting with," Billy said. He knew he was on dangerous ground, as he usually never went anywhere near the women in their underwear without female supervision, but something about this girl was drawing him onwards. He knew it had taken tremendous courage for her to come in today and he felt sure that if he made her come back later she would not return.

"OK then," Laura said nervously. The thought of stripping to her underwear in front of a man gave her goosebumps, but she also felt a shiver of excitement. With trembling fingers she slowly slipped off her jacket and kicked off her shoes. Then she reached down and slowly pulled her sweater over her head. Finally she unbuttoned her trousers, letting them fall to the floor. Now she was standing in front of a man in only her underwear. She felt her face flush and tried to avoid eye contact. "What do you think?" She said in a quiet voice. She quickly turned around to give him a view of her back and sides.

Billy just stood there speechless. He was staggered at how good a body this demure girl had been hiding under her baggy unflattering clothes. Though she was no super model, she was much slimmer than he had anticipated. Her legs were long and well toned with a nice swell to the calves and thighs. Her pants were very unflattering, high waisted and low cut, but even through them her buttocks looked soft and round, just how he liked them. She had a lovely stomach, not perfectly flat, but with a nice swell to it like a real woman rather than the stick insects he was used to seeing in the store. However what really caught his attention was her chest. Even though she was wearing a very unflattering full cup bra with thick straps, it was obvious she was very busty. The bra looked too small for her as well, which made Billy doubt the accuracy of the size. Despite his surprise, Billy's professionalism did not desert him.

"I think we can definitely improve this," He said. "I have to say your bra does nothing for you at all. I don't even think it is the correct size. Most girls want to make themselves look bigger in that department, all you need to do is emphasise what you already have."

Laura blushed. "Thanks you," she said, "but I really don't think I want to show off my chest too much. Alison says that doing that makes men think you are cheap and I don't want that."

'That explains a lot,' Billy thought. Alison was nothing special in the boob department, and was forced to wear push up and padded bras to make the most of what she had. The last thing she would want was her Plain-Jane friend to out shine her in that area.

"Definitely not," Billy said. "You just trust me, I know my job. If you try a few on I am sure we can get something you are happy with. As I said we can't take any measurements today, but I am sure that bra is too small for you. I think even an educated guess will be better than what you have."

"Well, if you think so," She said, her face going even redder. "This has been my bra size for a while now, but I suppose I might have got a bit bigger."

Laura felt a bit uncomfortable talking to a man about her bra, as she been self conscious about her chest for a long time. Still the tremors of excitement were there also and she knew she had gone too far to back out now.

"Yes, I am sure we can improve the fit considerably," Billy said. He walked over to a rack and picked out a black lacy bra and matching panty set. "Here try this, I reckon this size will be much better for you. It will be more comfortable and sexier as well."

"I don't know about black," Laura replied. "They look a bit skimpy as well."

"Nonsense," Billy said, eager to see this lovely young woman in the more flattering underwear. "This is just an ordinary every day underwear set, nothing too risky. Just give it a try."

She took the bra and panties as with a final nervous smile ducked into the changing room. Billy stood outside sweating a bit himself. He had never felt this way over a woman at work before. The combination of Laura's body and demure manner was something he found intensely exciting. He knew he would need to get a hold of himself or there was likely to be trouble.

"I am ready, coming out now," He heard from the changing room. The curtain opened and Laura stepped out. "What do you think?"

Billy was stunned. The lacy black French style knickers contrasted perfectly with her pale white skin and emphasised the length and tone of her legs and buttocks. The bra fitted almost perfectly and supported her large bosom much better, causing her breasts to stand out proudly for all to see. The bra was a quite conservative full cup design, but much better than what she had worn earlier. He looked her in the eye and saw she had noticed his appreciative glances.

Laura felt surprisingly comfortable. The bra did not dig in like her normal one, and she was sure from the look on his face that Billy found her attractive wearing it. She had never felt desired before, and loved the feeling of power. "Do you like it?" She asked.

"Very much, you look great," Billy stammered out. He felt the beginnings of a twitch in his groin and knew he was loosing control. Still he could not stop himself from pressing on. "That is an everyday underwear package, but I know you came here looking for something a bit special. Are you game to try something a bit more daring?"

"Why not," Laura said, enjoying the moment. She was gaining more confidence by the second from his responses towards her.

Billy walked over to the shelves and looked through the stock. He had intended on picking out a mildly revealing teddy, but his cock was getting the better of him and he found himself picking out the most revealing sheer white push up bra and thong set that the store stocked in her size.

"Do you mind trying a thong?" He asked tentatively, as if testing the water.

"OK, I will try anything you want," Laura said simply. All thought of Alison had gone out of her mind. She would do whatever this man asked of her.

Billy handed her the underwear and Laura retreated into the changing room. Once away from his gaze she sat down and let out a long breath. She quickly stripped out of the underwear she was wearing and pulled up the thong. She gasped as she looked at the brief garment, which barely covered her pussy. Luckily she had shaved down there the night before just in case, but her neatly trimmed bush could still be seen through the sheer fabric. The thong felt funny between her buttocks, as she had never worn one before, but at the same time was intensely arousing. She slipped the bra over her shoulders, did the clasp behind her back, and tried to get her breasts into the underwired padded cups. However she soon realised that the brief cups barely covered her nipples and there was no way she would be able to fit in fully. The bra forced her large melons into a shockingly revealing cleavage like she had seen in the wonderbra advents. She gazed at herself in the mirror turning from side to side, examining her swollen mounds of flesh forced up and out of the push up bra. Part of her felt very self conscious and did not want to leave the changing room, but another part was aching to see what Billy's response would be to seeing her in such sexy underwear. She turned face on again and gasped quietly as she noticed that her dark nipples were poking through the cups of the bra, obviously erect. She felt a slight moistness between her legs and for a second had an almost overwhelming desire to reach down and rub her clit, but quickly shook herself out of that daydream. She wanted to see what Billy though of her new look. She reached up and pulled the clasp out of her hair, letting it drop down to her shoulders. Then turned to the curtain of the changing room.

Outside Billy waited impatiently for her to emerge. His mind was conjuring up images of what she would look like in the skimpy underwear, and he was struggling to control his body even thinking about her. He was wearing tight boxer shorts under his trousers and felt his cock swelling slightly against the thin material. He was so turned on by this demure goddess that his rule of never dating customers was close to going out the window. He decided to just go with the flow and see where it took them. Then he heard a rustle of the curtain and looked over to see Laura emerge.

This time he was truly blown away. Her legs looked even longer now she only wore the brief high cut thong which barely covered her pussy, and through which her dark pubic hair was clearly visible. His gaze rose over the delicious curve of her belly, up to the skimpy white push up bra that was doing its best to contain her magnificent breasts. Her creamy white boob meat spilled out of the top and over the sides of the bra, while her nipples were barely covered by the cups at the front. Even then he could see the dark outline of her areolas through the thin material. Finally he looked up and saw a wide grin on her face. Then he realised her gaze was at the front of his trousers. The sight of her in such revealing attire had made him loose control of his cock, which had reared up inside its tight cotton prison and was now making a noticeable bulge in the front of his trousers

Laura had never felt sexier than at that moment. She had expected Billy to be appreciative of her, that was after all part of his job, but the obvious erection she had given him was even better. Then she saw he had noticed her staring at his groin, and they both looked away embarrassed.

"What so you think," Laura whispered quietly.

"I think you look wonderful," Billy replied. All pretence at professionalism was over. He didn't even care about his job anymore, or that she had seen his obvious arousal. All he wanted was to touch this woman.

Laura bent forward slightly causing her huge melons to fall forward against the bra. The tight padded cups pressed them together into a wonderfully tight cleavage that seemed to go on forever. Then she turned around slowly, giving Billy a good view of the sides of her boobs bursting out the bra, and then her full luscious buttocks completely exposed apart from the brief thong, which ran between them. When she turned back round Billy had taken another few steps closer and was now within touching distance. Part of her felt scared, she had never been this close to a man wearing so little, but another part was enjoying it thoroughly.

"Do you like my breasts in this bra?" She asked playfully, as she reached up to her magnificent melons and cupped them, pushing even more of the voluptuous flesh out over the cups. "Alison would think I looked like a cheap tart dressed like this, but I don't feel like one. I feel sexy."

"You look it too," Billy responded. "But I am still not sure if the bra is fitting you properly. I hope you don't mind if I just take a small measurement with you wearing it." He was still not sure exactly how far to take this. Laura did not seem very experienced, and he did not want to upset her. Still he felt an overwhelming desire to touch those luscious tits, and thought the pretence of measuring her would give him the excuse.

He got his measuring tape from his pocket and walked round behind her. She tried to follow him, but he reached out and clasped her head between his hands, turning it forward so she was looking at herself in the mirror, and he could see her reflection over her shoulder.

"You just look forward and relax, this will only take a second," He said, quietly in her ear. Billy quickly ran the measuring tape across her back to measure the width, then brought both hands round her front to pull the tape tight across her bosom. However, as he did this Laura move backwards, pressing her buttocks into his groin. He felt his cock twitch and swell up even more; there was no way that she had not felt it.

"Sorry," she giggled. "The tape was a bit cold on my chest."

"That is OK," Billy replied. "I am almost done." He reached over her shoulders and tugged the bra straps a little to check the tension. Laura felt the cups tighten against her chest, which caused her nipples to harden up even more, she was sure they were going to pop out of the bra any minute if he kept that up.

"We could do with tightening the straps a little here," she heard him say. "With a bra like this the fit must be perfect if you want to avoid an embarrassing accident at the wrong time."

Laura felt his hands move from the straps forward and for the briefest of seconds the tips of his fingers ran over the top of her breasts. She felt a twitch from his cock wedged up against her buttocks, and let out a small moan herself. She arched her back up trying to keep the contact for as long as possible. However that was exactly the wrong thing to do wearing such a skimpy bra. As Billy had said might happen, the extra tension her arched back created overloaded the already straining cups, and with the shoulder straps not tightened correctly the bra slipped slightly, exposing her erect nipples.

Billy gasped as he saw those delicious little buds uncovered for the first time. He felt another twitch of his cock, now almost fully erect, and had to suppress the urge to put both his hands on her boobs and rub her hard nipples. However he knew this would be too aggressive a move with this inexperienced young girl and he doubted she would respond favourably. Instead he croaked out.

"I see you have had a little accident there as I predicted, I think we will have to adjust the fit a bit."

Laura looked confused for a second before she realised her bra had slipped, exposing her aching nipples to his gaze.

"Oh, I am so sorry," She gasped out, pulled and away and adjusting the bra to cover herself back up. "Perhaps this isn't for me."

"Nonsense," Billy replied. "You look wonderful in that outfit, certainly as good as any of the other girls I have seen in here, including Alison."

He looked her straight in the eye, his lust clearly evident. He was hiding nothing from her, and wanted to see if she would make the next move.

Laura's stomach was churning. It was obvious Billy desired her, but she had never been with a man before and did not know what to do. However she knew she had to do something, if she let this moment pass she would regret it for the rest of her life. She took a step forward and gathering all her confidence she slowly and tentatively reached out and touched the bulge in his trousers. She immediately felt another twitch from his engorged penis as she gently stroked it through his trousers.

"Yes, I can see you like me in this," she whispered quietly, trying to sound as sexy as she could. "However I think it would only be fair if I could see you in your underwear as well."

"I think that is fair enough," Billy replied. He reached for his belt and unbuckled it, before unbuttoning his trousers and pushing them to the floor. Then he pulled off his shirt and kicked off his shoes so he stood in front of her in only his tight boxers.

Laura gasped at she examined the huge bulge that was distorting the front of the boxers, amazed the sight of her body could do this to a man as attractive as Billy. She dropped to her knees so her face was only inches from his swollen groin.

"I see I am not the only one, who has trouble fitting into my underwear," she laughed, her nervousness draining away at the sight of his obvious arousal.

"I think you might be the cause of that," Billy replied. "I don't suppose you could do anything about it could you?"

Laura felt light-headed hearing that. Did he really want her to remove his boxers! She looked up at him and the ardent desire in his eyes gave her the answer. She took a deep breath and slowly reached for the waistband of his boxers, before slowly tugging them down to expose his erect manhood. This was the first erect penis she had ever seen in real life and she was not disappointed. It thrust out from his body aggressively, twitching slightly with every breath. Laura reached out her hands and slowly ran them over its entire length. When she reached the tip she felt another twitch, which told her she had hit the jackpot. She gently rubbed her hands over the tip with increasing vigour and she heard him moan and the twitching of his cock became more frequent.

Billy was loving her gentle touch on his cock but felt horribly close to cumming already. Normally premature ejaculation was never a problem for him, but this girl had got him so aroused he didn't think he could hold on too long. Also the fact he had not been with a woman for many months, since he had stopped dating customers, did not help. He had to stop her now or risk cumming all over her then and there.

"That is great Laura, but you must stop now," he moaned. "I am too close to cumming and don't want that till I have given you some pleasure."

Laura smiled mischievously; glad her ministrations were having the desired effect. She gave a couple of hard tugs, taking his to the brink of orgasm, before stepping back.

"What do you have in mind," She said, eager to explore her newly found sexuality.

Billy pushed her back into the changing room quickly and drew the curtain. He sat her down on the seat before kneeling down in front of her.

"I think we had better do this in here," he said. "The shop is shutting in 5 minutes, but I don't want us disturbed before then."

He reached down between her legs and gently parted them so he could gaze at her pussy, still covered by the thin sheer thong. He could see the material was already a bit damp from her juices, but wanted her a lot wetter than that. He slowly lowered his head to just in front her pussy and began slowly licking her through the thin material.

Laura was delirious with desire. She didn't know that men did that to women and could barely stop herself reaching down and ripping the thong off so he could get even closer to her. She arched her back pleasure and felt the bra tighten across her swollen nipples again.

"I have got to take the bra off Billy, it is too tight" she gasped.

However Billy didn't want that yet. He stopped his tender licking between her legs and looked up.

"Not yet love, keep those gorgeous tits in their prison a bit longer. I will come to them later."

Then he started between her legs again. By now the front of the thong was soaked through and her pussy lips were clearly visibly, as was the swollen nub of her clit. Billy reached up and quickly pulled the thong to one side to get better access. Her pussy was wonderful, her neatly trimmed pubic hair framing her wet pussy lips, with her erect clit throbbing away at the top. He gave the clit a light lick and felt the beginnings of an orgasm welling up.

"Oh Billy, do that again. That feels wonderful," Laura gasped. She had rubbed her own clitoris when masturbating, but it hadn't felt anything like this. Billy gave another lick, while at the same time inserting a finger between the folds of her vagina. Laura felt another pulse between her legs and knew it would not take much more for her to cum. However at that moment she knew it would not be enough to satisfy her rampant desire. She needed to feel his cock inside her.

"Stop Billy," she gasped and lifted his head up from her pussy so she could look him in the eye. "I need to feel you inside me, please make love to me."

Billy was astonished to hear this. It was quite obvious from the tightness of her pussy, and her manner earlier that she was a virgin. He could not believe she was willing to give her virginity less than an hour after meeting him.

"Baby, there is nothing I would like to do more. However I think we should do something about those wonderful tits first."

Billy reached up and gently cupped her tits though the tight bra. He massaged the exposed upper part of her breasts while with his thumbs he rubbed the front of the cups where he knew her nipples must be. He felt them harden, even through the bra, as she moaned loudly.

"Oh Billy take it off please, I need you to suck my tits now. I can't take any more."

Billy lowered his head into her magnificent cleavage and licked the tops of her breasts, gently at first, but then with more aggression, moving closer to the edges of the cups. Then he reached for the clasp at the back of the bra and expertly undid it, but instead of removing it, he held the bra tight over her tits, despite her moans to remove it. Finally he inched the bra down, again exposing her erect nipples to view, before throwing the bra to one side and gazing at her now finally uncovered chest.

He almost came than and there at the sight of those magnificent mammeries. They sagged slightly due to their size now they were unsupported by the bra, but Billy though they were the most beautiful pair of tits he had ever seen in his life. The creamy white boob meat seemed to go on forever and the light brown areolas and nipples that topped them just begged to be sucked. Billy cupped her tits in both hands and pushed them together so he could alternately lick each nipple from side to side. He bit lightly on them one at a time while Laura gasped in pleasure. Then he felt her hand move down between his legs and once again start rubbing on his rock hard cock.

Laura felt his cock give a twitch and knew he was as aroused as she was. She could see her breasts were driving him crazy and knew how to get him even more excited. She gently pulled back from him, giving him a coy smile, before sliding down his body till her chest was level with his cock. Then she cupped her huge melons and pressed them round his rock hard erection, before slowly sliding up and down. Billy gasped with pleasure as he felt his cock slide inside her warm silky cleavage. Precum seeped out of the head of his cock, lubricating it as it dipped between those mountains of luscious boob meat. Billy felt his balls beginning to tighten and knew he would not be able to take much more of this.

"Laura, you have the most wonderful set of tits I have ever seen," Billy said, his voice thick with lust. "I think I could cum just looking at them." He put both hands round her head, lifting her up to his level and kissing her full on the lips. He ran a finger back down between her legs and gently rubbed her engorged clitoris thorugh the thong, feeling it throb as he did. Laura moaned and broke the kiss, looking him directly in the eye.

"Please don't tease me any longer baby, put your lovely cock in me!" Laura gasped. She couldn't believe she was saying this to a virtual stranger. A small voice in her head was crying out at her to be sensible. Not only was she a virgin, she was not on any form of birth control and had absolutely no experience in this sort of thing. However the ache between her legs was now unbearable and she knew only full sex would satisfy her now.

Billy's mind was also in turmoil. He badly needed so sink his twitching rampant cock into her sweet pussy, but knew this was her first time and didn't want to take advantage of her any more than he had. He also was pretty sure she was not on the pill, and as he had no condoms, any sex with her would be risky. "I will just have to pull out before I cum," he thought. "She seems pretty horny, I should be able to hold on until she had came. Then I can safely pull out and cum over her tits."

With this flimsy justification in mind, Billy reached down reaching down, pulling her flimsy thong off completely and exposing her luscious pussy. He moved forward so the tip of his cock gently rubbed against her pussy lips, but with enormous willpower stopped him from thrusting into her.

"Are you sure you want this?" He asked her gently.

"Oh yes Billy, please don't stop. I need this so bad," Laura moaned. She arched her back again, thrusting her tits against his chest and pushing the tip of his cock between her pussy lips. Billy couldn't take any more. With one almighty thrust he pressed his cock deep into her pussy.

Despite the tightness of her pussy, she was so well lubricated his cock slipped in quite easily. Laura felt the momentary sharp pain that told her she was no longer a virgin, but after that a deep feeling of pleasure began to radiate from her clitoris, onto her pussy and right up her whole body. She gasped and began pushing against him, eager to get into a rhythm. Billy felt her moving against him and knew what he had to do. He slowly pulled back so his cock almost withdrew completely, before pressing back in equally slowly.

"Billy, please," he heard her gasp. "Push into me harder and faster, don't tease me!"

Billy was only too happy to obey. He reached up with both hands, cupping her heaving tits and massaging them roughly, and then he began gradually increasing the rhythm of his thrusts, going deeper and deeper into her hot wet pussy with every stroke. Laura was in ecstasy, her pussy was on fire and waves of pleasure racked her body as her clitoris was stimulated by each thrust. She began pressing back against him herself, arching her back and thrusting her huge boobs into his hands at the same time. Then she reached between their bodies and took his throbbing balls in her hand, gently squeezing them with every thrust. After only a few minutes of this Laura felt the spasms of pleasure getting more frequent and knew she was on the verge of cumming. However at that moment a very irrational desire came over her. She wanted him to cum inside her. Even knowing she was on no birth control and had no protection from possible pregnancy, the thought of his hot sperm pumping inside her was unbelievably exciting to her.

"Oh Billy I am so close, keep going baby I need you so much," She moaned.

Billy was beginning to gasp in pleasure himself. He could feel every spasm of her internal muscles gripping the sensitive head of his cock and the friction against the ridges of her vagina was forcing him closer to his own orgasm. He very rarely has sex without a condom, and felt his self-control beginning to desert him. Still he knew he had to pull out before cumming.

"She can't last much longer," He thought to himself. "I just need to hold on another minute or so." Still the pressure on his balls was becoming unbearable, especially with her squeezing them with every stroke, and he knew when he did come the load would be massive. Suddenly he felt a further tightening of her vaginal walls and knew her orgasm was imminent.

"Ahh baby I am cumming," Laura moaned. "Please cum with me, I need to feel you spurt inside me."

As she shouted this pussy began rapidly spasming against his cock, and she squeezed his balls hard. Billy felt them contract and knew he had to pull out now, but her shout of encouragement had forced all rational thought out of his mind and instead of withdrawing he pushed into her as deep as he could, so the tip of his cock was almost against her cervix. His balls gave an almighty pulse and the first spurt of cum was forced from deep in his balls up his quivering cock and deep into her unprotected womb. Laura felt it immediately and gasped in pleasure.

"That is it love, please don't stop, I need you to cum in me."

Billy was lost in the throes of his orgasm now; all thought of birth control was gone. Pulse after pulse of potent semen spurted from his cock deep inside her virgin womb. At the same time the contractions of her orgasm sucked his semen deeper and deeper toward her fertile eggs. This was the best orgasm he had ever experienced and it seemed to go on forever, more and more cum spurting from his cock with every thrust.

Finally he felt the spasming of her vagina lessen as her orgasm finished and some form of rational though returned to his mind.

"What have I done," Billy though in horror, pulling out as quickly as he could. He looked down and saw the last few spurts of cum splash from his cock onto her pussy and belly. However he knew the bulk of his load was now deep inside her, the sperm swimming towards her eggs, nothing in their path to stop them.

"Oh Laura I am so sorry, I didn't mean to do that. I couldn't help myself. Are you on the pill?" Billy said, in false hope, already knowing the answer.

"I am afraid I am not Billy," She said quietly. The enormity of what they had done was now hitting home with Laura as well. However she was not angry at Billy, she had egged him on and had not given him a chance to withdraw. She knew she was as responsible for the situation as he was. "It is OK Billy, I don't blame you," she continued. "That was the most wonderful thing that has ever happened to me, and I am willing to live with the consequences, whatever they are."

She looked down the saw his semen leaking out of her pussy. At the same time a wonderful warm feeling of contentment washed over her.

They lay there naked in the changing room for several minutes before getting dressed quickly, not saying a word. Laura put on her original underwear and clothes before walking to the door. Billy didn't know what to say. He had broken his cardinal rule, taken advantage of an innocent young girl and felt ashamed. However he badly wanted to see her again. Sex with her had been the best he had ever known, and already he wanted her again. However before he could think of anything sensible to say he turned around and she was gone. "I must have upset her," Billy thought guiltily.

Billy spent the next few days in anguish, unable to get the image of Laura out of his head. He was also worried about the possible consequences of their unprotected sex, and did not want her to think he did not care. He finally worked up the courage and went to see her at the library. He brought with him a parcel.

As soon as he walked in he saw her at the desk. She looked up and smiled as he walked in. This gave him some hope, as she seemed pleased to see him.

"I have brought you a present," Billy said nervously, handing her the package. She opened it to find the thong and bra set she had worn that fateful night. "I don't really think we could sell this now," he laughed.

"Billy, I am so glad to see you," Laura said happily. "I am sorry I ran off that night, but I didn't know what to say or do. I wasn't sure if you though you had made a mistake or if you even wanted to see me again."

"Laura, I definitely want to see you again," Billy laughed. "As often as possible."

They started going out immediately, much to the annoyance of Alison and her "in crowd" friends. After several weeks it became obvious that Laura was pregnant with Billy's child, and they moved in together. Billy continued to improve the sales in his department and was soon promoted to assistant manager of the whole store. However he always remembered his time at the underwear department very fondly, and took an active role in the running of that department. He frequently brought home the newest and sexiest underwear lines for Laura to try in the privacy of their own home, and they both enjoyed these "special fittings" almost as much as the first one.
