The App

[Namb]

I was encouraged to republish this story here by a fellow member (SuperEvil7)

A girl invents an application for her phone that causes boys to get an erection. She tries it out on her lab partner, Greg. Things get more complicated when she becomes romantically involved with her subject.

-=In the Lab=-

Greg Walters looked at his watch. “Oh good, I got plenty of time and I don’t have to rush to get to Chem Lab,”

As he pushed open the door to enter the lab, he saw that his lab partner, Eileen Scott was already there

He liked having Eileen as a lab partner. She was the most brilliant student in the class – the most brilliant student in the whole school.

There were a few girls in the school that got a jump start on puberty and they knew it. They were the ones with the pretty faces, the shapely figures and they flaunted it by pushing the boundaries of the school’s dress codes with tight blouses and short skirts.

Eileen was like almost every OTHER girl in the school. She had a pretty face, not one that would launch a thousand ships, but nice enough. If she had a figure, it was hidden by a modest blouse, jeans and sneakers: the baggy sort of wardrobe that most of the girls seemed to favor.

About the only thing about her that made her different was what Greg thought looked like oversized glasses that made her look more nerdish than she deserved.

She was also a bit on the shy side and that added to her reputation as a brainiac.

Greg was glad to have her as a lab partner. She was helping him get a good grade. So what if she was a girl?

“Did you get the answer to question 6?” Greg asked her. “I couldn’t work out the valences.”

“Well, you have Sulfur, and it has 6 electrons to spare. Think of it like the atom has a north, east, south and west side and each side has a box that can contain a maximum of only two electrons.

Now suppose you want to spread those 6 electrons out as evenly as possible. How would you do that?”

Greg thought about it for a couple of seconds and said, “Two electrons in two boxes and one electron in the remaining two boxes.”

“Exactly! Now you have the Oxygen atoms. They have two electrons to share. Electrons in the outer shell always want to pair up with atoms from other atoms except for the noble elements. Their table is full, so to speak, so they don’t form compounds with anything.

So the two of the Oxygen atoms pair up with the two boxes on the Sulfur that have two electrons, so they’re happy.

The other Oxygen atom and its two electrons, has to mate up with the boxes that have only one electron each. Got it?”

“So a total of six Oxygen electrons matches up with the six from the Sulfur atom.”

“You got it, Greg! So what you have is Sulfur Trioxide: SO3.

When you mix it with water, H2O, the atoms shuffle around and you get H2SO4 or Sulfuric Acid.”

“It all sounds so simple when you explain it. I wish old Ms. Bellweather could explain it that well.” Greg appreciated that Eileen was never condescending when she explained what was obviously simple to her in terms that he could understand.

The bell rang and Eileen poked at her phone, apparently to silence it in accordance with school policy.

As Greg opened up his lab book, he felt a stirring in his pants. He was getting an erection. There was absolutely no reason for it, it was just happening. He hated when that happened, sometimes it would just stiffen as if it had a mind of its own.

He figured that it would go away once his mind was distracted by the experiment Eileen and he were about to perform.

He donned his lab apron early hoping to hide the bulge in his pants.

Normally, erections of this kind go away in five or ten minutes tops, especially with his mind attempting to concentrate on another task.

Unfortunately, that didn’t happen. His penis stayed hard for at least half the class and then it slowly abated. He could feel the wetness of his precum in his underwear.

He made it to the boy’s bathroom after class, got into a stall, blotted up the outside with a paper towel and put a wad of toilet paper inside to keep his penis dry. He was glad he was wearing dark pants so the staining was barely noticeable. It was almost as bad as a wet dream.

-=o=-

Meanwhile, the girls’ bathroom was a cacophony of girlish chatter.

“Did you see the boner on Brian?” one girl exclaimed.

“No, I was busy looking at the one on Timothy.”

Almost every girl had a comment about one of the boys in the chemistry lab and how each of them seemed to have a bulge in his pants.

One of the girls, Sharon, exclaimed. “There seemed to be an epidemic of hard-ons. Maybe someone put Viagra in the water. Hey, maybe we can put Viagra in the swimming pool. Can you imagine what the boys’ swim team would look like in their speedos?

Too bad the boys wore a protective apron for most of the class. I can’t wait to get to my next class. I’m going to check out all the boys to see if they still got a woody going.”

Eileen noted that a couple of the girls mentioned Greg’s name. She didn’t fail to notice his erection, but unlike the other girls and even the boys themselves, she knew why.

-=o=-

The kids at school were not the only people to recognize Eileen’s academic abilities. Her parents were also tuned into both her intelligence and interests. Because of her brilliance, she was advanced a grade, making her at least a year younger than her classmates. She could have advanced some additional grads academically, but her parents were smart enough to hold her back for the sake of her emotional development. She needed to attend school with children close to her own age.

First, get her through middle school then maybe have her start college a year early. They had no doubt that she would win a scholarship.

In the meantime, they did all they could to help her develop herself intellectually. She expressed an interest in potentially becoming a doctor, so her parents bought her an account that granted her access to medical papers and the libraries at several medical schools.

But Eileen was also a tween and her interest in the male gender was shifting. At the moment, she had no specific romantic interest, but she was curious about boys.

She could hardly remember when she learned about “the birds and the bees.” Her parents were good at answering her questions, and she had both a medical curiosity and a schoolgirl interest about human reproduction. As precocious as she was, she asked questions early.

She had a girl’s body and experimented with it and knew what it was like to be female. She wanted to know more about what it was like to be male.

Her access to the medical data gave her much more knowledge than her contemporaries. Many of the girls had brothers and knew what penises looked like. There were a few poor girls who didn’t and they had to make do with the stick figures in their Human Development textbooks.

Eileen knew the fine details. She knew the inner workings of the penis and even had cross sectional views of the tissues and tubes. She had the scientific name of every part of the penis memorized.

She knew what a penis looked like literally inside and out even though she had never actually seen one.

Not only did she know the anatomy, but she also studied the physiology: how the organ worked.

So she knew about erections and how, from a medical standpoint, they and ejaculations were caused.

She also learned some about the pathology: things that can go wrong like venereal diseases, Peyronie's disease and erectile dysfunction.

The latter fascinated her and she researched the topic extensively.

This research led her into other areas of medicine outside of the physical body: namely, human sexuality. None of the material she had access to was outright pornographic, but when she studied the psychology of sex she found a lot of it was very explicit even if clinical including things like fetishes and practices such as female domination.

But it was the TV commercials that steered her interest in researching erectile dysfunction. She learned that in many cases, erectile dysfunction was psychological in nature and could be treated with therapy, some cases were cured with “better living through chemistry” e.g. Viagra and similar drugs and some cases required surgery and in some cases, the system just needed a “nudge” with a non-surgical procedure.

One such procedure was “wave therapy.” Wave therapy uses ultrasonic vibrations to stimulate body parts. It has application in the healing muscles damaged by injury or surgery and it can also be used to stimulate bone growth in fractures.

It was all a matter of getting the right frequency for the body part to be stimulated. She discovered the frequency to cure erectile dysfunction in her research.

Her next project was to program an oscillator to produce that signal and transfer it to an app on her phone.

She had no way to know whether it would work, until she tried it.

Her experiment in the lab proved her success. Unfortunately, the app ate power at a very high rate and drained her phone. She could only run it for about 30 minutes until her phone went dead. She had to spend the rest of the school day with essentially a brick in her purse.

-=It’s a Date=-

“So, how did you do on the math test?” Eileen asked Greg after the last class of the day for both of them.

“I got a B+ and I supposed that’s not bad, but I think if I pushed just a little harder, I could get an A. The problem is, it takes so long to figure the word problems out.”

“It’s really not that difficult. There are only a handful of different types of problems. Once you figure out which kind of problem you are working on, it all falls into place. What you have to do is look for some key words like ‘of’ or ‘more’ and you’ll know when to multiply or divide or add or subtract.”

“So what you’re telling me is that I need some kind of a dictionary.”

“Well, it’s not quite that simple. You have to develop a sense for the question being asked: some are ratio problems, some verbally describe an equation, some are even a matter of eliminating the impossible Sherlock Homes style. There are only a handful of types. Once you’ve seen a dozen or so, you’ll catch on to what kind of a problem you are working on.”

“It all seems so confusing.”

“No, it’s not. If you want, I can walk you through some examples. Once you catch on, you’ll find that it’s really simple.”

“You’d do that for me?”

“Sure, why not? Why don’t you come over my house tomorrow morning; it’s Saturday and it’s supposed to rain anyway? We’ll go through some problems and work on them together. I’ll show you what to look for.”

“Yeah, OK, but don’t make it too early. I like to sleep in.”

“How about 10 o’clock?” She laughed.

“It’s a date,” Greg said, but wondered, “Does this really count as a date? After all, I am seeing a girl outside of school hours. OK, it’s a ‘study date’ but it’s still a date, sort of.

Eileen is a girl and she’s my friend, but does that make her my girlfriend?”

Greg put the thought aside as he packed up to go home.

-=o=-

Greg got up the following morning, ate breakfast, took a shower, brushed his teeth and got dressed. He said to his mom, “Mom, I forgot to tell you, I’m going over a friend’s house to study for my math test. I don’t know how long this will take, so I may be late for lunch.”

“So who is she?”

“She?”

“The she you’re going to study with. You don’t take a morning shower and get dressed that nicely to go study with your male friends. In fact, you never study with your male friends at all.”

Greg laughed, “OK mom, you got me. Her name is Eileen. She’s also my lab partner in Chemistry.”

“Eileen Scott?”

“Yes, that’s her. How do you know her?”

“First of all, I saw her name on one of your papers. Secondly, her mother volunteers down at the shelter where I work. She seems like a nice woman. If her daughter is anything like her, you should do well.”

Greg gave his mom a peck on her cheek and ran off. She shouted after him, “Thanks for the warning. You’re on your own for lunch.”

-=o=-

Greg arrived at Eileen’s house right on time. He was a bit surprised when she answered the door. Instead of her normal school clothes, she was dressed in a tight T-shirt and very short shorts. The girl did have a figure and very long and shapely legs. She definitely did not conform to the dress code outlined by the school, but this was her house and she could wear anything she wanted.

He was also impressed by her house. It was a bit more upscale than his own and they even had their own swimming pool in the backyard.

Eileen introduced him to her mom. Mrs. Scott replied, “So this is Greg. I’ve heard a lot about you from your mother. I’m pleased to meet you.”

Dad’s not here. He’s on temporary assignment for a couple of months in Saudi Arabia with his job, so mom’s staying here so I can continue my education uninterrupted.

Let’s go to my room so we can study.”

Greg felt intimidated. First, he’s at a girl’s house and now he’s in a girl’s room. Unlike his own room, which was sort of disheveled, Eileen’s room was quite orderly. It seems like she had shelves for everything. Mostly they contained books, but they also contained pictures, stuffed animals, dolls and figurines.

The main colors were pink and purple and everything seemed to have a frilly and feminine appearance.

Greg had seen something similar through the doorway to the bedroom of one of his female cousins, but that was “no man’s land;” he was forbidden to enter.

Now he was in the Holy of Holies of one of his classmates. It just made him feel uneasy.

“Let’s sit at my desk and I’ll get my math book. We’ll go over all the problems, not just the ones assigned for homework. In case you didn’t notice, Mr. Bean likes to use non-homework problems on the test.”

She pushed her laptop from its center position to the side and placed the textbook in front of Greg.

She sat next to him. Not close enough to touch, but close enough that he could feel the heat from her body. It was also then that he noticed her scent. Was she wearing some kind of perfume? He wondered if there was more date than study in this study date.

Eileen was all business as she had him read the problems and then made comments on them and then questioned him on them. Not only did she know her stuff, she was a good teacher. She led him to the point where he could make his own conclusions about the problem.

Soon he was stepping through them easily.

“Wow, Eileen, you were right. This is simple once you see it.”

“We’re done early,” she said. “How about we hit the kitchen for a snack and if you want, we can do next week’s math so you can breeze through it.”

“That sounds great,” Greg said.

As they were sitting at the table in the kitchen, Eileen’s mom came in. She was wearing a very revealing tennis outfit. Greg immediately thought of the song, “Stacy’s Mom.” This woman was a knock out. Too bad she was 25 years too old for him. When he looked at her, he could see what the future Eileen might turn out to look like. It was a pleasant thought.

She smiled at them, “I just got a last-minute invite to play tennis with Mrs. Bridgeford. She’s a major donor at the shelter. I want to stay in her good graces.

I’ll be gone for a couple of hours. Greg, if it’s OK by you, would you mind staying on? I don’t like the idea of Eileen being in the house alone.”

“It’s OK Mrs. Scott. I already told my mom that I would be late for lunch.”

“Call your mom and tell her you’ll have lunch here. I’m sure Eileen can take good care of you. There’s plenty of baked ziti in the refrigerator, all you have to do is heat it up.”

The kids finished their snacks and cleaned up the kitchen.

-=In Her Lab=-

“Let me show you something,” Eileen said. Instead of leading Greg back to her bedroom, she led him to the basement.

Greg was amazed. She had a complete laboratory there!

She plugged in her phone. “This thing uses so much power.” She lamented. She gave it a couple of taps and set it down.

“Let me give you a tour of the lab.

I don’t normally let people see this,” she explained. “This is my private world. This is where I would spend all my time, if mom and dad didn’t insist on my coming up for meals and to attend to my school work.

They’re pushing me to get out more and make friends. I have friends, but they’re all at school. I think mom and dad are right. I do need more of a social life.

You’re the first friend I’ve had to the house since we moved in. I was hoping you could be my friend and maybe through you, meet your friends.”

“I don’t know if you’d like them. They’re all boys. Some of them are not interested in girls and others are interested in girls in the wrong kind of way.”

“I know. Boys don’t find nerdy types attractive and intelligent girls scare them off.”

“Well, I’m not afraid of you.”

“You’re not, aren’t you?”

“Well, first of all I know you. Secondly, you’re nicer than you are smart. Don’t take that the wrong way, you ARE smart, but you’re also very nice.

There’s something about you that makes you – you. You’re not out to impress other people with a fake personality.”

“You mean like Gina Piccard.”

“Her and most of the rest of the cheerleading squad.” Greg laughed. “If you added all their IQs together, they still wouldn’t be half as smart as you. I’m not sure that they’d be smarter than my dog.

You’re smarter than me, but you are willing to share your smarts with me. You don’t lord your intellectual superiority over me, you actually use it to help me. How can I be afraid of that?”

Greg enjoyed talking with her, but maybe it was the fact that he was having conversation with a real girl as a girl and not just his classmate or maybe the way she was dressed was having an effect on him. At any rate, he was getting another unbidden erection just as hard as the one he got in class.

“Oh, Greg, I really do want you to be my friend and not just because I help you with your schoolwork.”

“I like that, but I like you too.”

Greg saw Eileen blush. “What’s the matter?”

She giggled, put her hand to her mouth and with the other, pointed to his crotch. “You have an erection, don’t you?”

It was Greg’s turn to blush.

She seemed to enjoy his discomfort and pressed on. “Just like yesterday in the lab.”

“You saw that?”

“Every girl saw it. We girls have signals we give one another when we see boys with hard-ons. It wouldn’t do to be the only girl in the class to miss out on the action.

Oh, don’t worry, you weren’t the only boy with one. All of you had them.

You didn’t notice?”

“Um, I’m not in the habit of checking out other guy’s junk. I’m not gay or anything.”

“I guess girls are just more attentive than boys then.”

Greg was very uncomfortable with the turn the conversation was taking. Also his erection showed no sign of going down and it was getting downright uncomfortable.

“So how does it feel when you have a boner?”

“I don’t know, it’s just there. Most of the time I’m not even aware of it unless it gets very hard.”

“And are you very hard now?”

Greg swallowed and nodded.

“Poor boy. I’m glad I’m a girl and I don’t have to put up with those things. Eventually, I’ll have to put up with my period, but that’s only a couple of days a month. It seems boys are hard every day.”

Greg could feel his underwear getting damp. “Eileen, can I use your bathroom?” He intended to do his blotting and padding exercise again.

However, when he got in the bathroom, his erection was too much to bear. It was leaking precum at an alarming rate. Was something wrong with him?

He knew of only one way to quench it. He pulled his pants down to his knees and knelt before the toilet. It took only a couple of strokes for him to ejaculate. It was a very forceful cum.

It took him a while to calm down. Eileen was waiting for him when he got out.

She smiled smugly at him and said, “I know what you did in there.”

Greg blushed again.

I didn’t hear any peeing. Instead I heard some heavy breathing and some grunting. Also I peeked under the door. I thought boys stood up to pee. You were kneeling.

Let’s take a look, shall we?”

She went into the bathroom and lifted the seat. “Come here Greg, take a look!

What’s that stuff on the back of the seat? Were you so excited you shot it that far?”

“How do you know about this stuff?”

“I read a lot,” she giggled.

“I think I better go.”

“You can, but if you do, you are in for some more embarrassment at school.”

“What do you mean?”

“What if you had erections all day long at school? Would you like that?”

“No.”

“I can make you and all the boys around you have an erection.

Would you like a demonstration?”

“What kind of demonstration?”

“You’ll see. Tell me, are you still hard?”

She got a nod as a response.

“And that’s immediately after beating off. Wow!

Come with me. I have something to show you.”

She led him across the room and picked up her phone.

“See this app here?”

“Yes.”

“Watch what happens when I turn it off.”

“Nothing’s happening.”

“Give it a minute.”

She tapped her foot and hummed a tune to pass the time.

“So, how’s it hanging. Are you still hard?”

“A little.”

“It’s gone down since I turned the app off.”

“That’s just a coincidence.”

“OK App on.”

Greg sweated as he waited. Slowly his penis started rising again.

“OK, OK you win. Turn it off.”

“I thought boys liked having hard-ons.”

“Sometimes, but not constantly. It’s very annoying if it lasts more than a couple of minutes without … well, you know.”

“I DO know. I just saw the effect it had on you.”

“What’s going on here?”

“I developed an app that sends out a sound wave that stimulates the nerves and such that cause erections. It was a matter of finding the resonant frequency and then …

I can explain all the details if you want.”

“I’m sure I wouldn’t understand it. Sound waves, you say? I didn’t hear anything.”

“That’s because the frequency of the waves is well outside the range of human hearing.”

“It was weird. Just like in the lab. I was getting hard and I couldn’t do anything about it. It was like some thing or some one else was taking control.”

She giggled again, “Someone else did take control: I did and I did it with this,” she added waving her phone. “Back in the lab, it affected all the boys. Us girls, not having penises, were immune.

I wonder what the reaction would have been if I kept it up – if I kept all you boys up – longer.”

“Why are you doing this to me?”

“I need your help.”

“What kind of help?”

“I don’t have a penis, so I need yours.”

He looked at her in shock.

She laughed, “No I’m not going to castrate you or anything like that. I just need to see how this thing works with penises. I still have some fine tuning to do.”

“So what do I have to do?”

“Get naked.”

“What?”

“It’s just the two of us. It’s for science. It’s the only way I can get some of the measurements I need.”

Greg felt put out at being used as a lab rat for Eileen’s experiment. “What’s in it for me?”

“I’ll only give you an erection if you want one. Admit it. You had a great time in the bathroom a while back. I can make that happen at will.”

“At YOUR will, not mine. Are you going to get naked, too?”

“I can’t.”

“Why?”

“Seeing a naked girl, even me, might give you an erection without the use of the app. It will skew the results.”

“Please don’t do this to me, Eileen.”

“Come on, Greg. We’re friends. I’m not going to harm you. I just need some data. I’ll be gentile and you might even like what I’m doing. Let’s at least try it and if you don’t like it, we’ll stop.”

“Are you sure I have to get naked for this?”

“Absolutely.”

“I can’t believe you are even asking me to do this.”

Eileen started crying, “Greg, I wouldn’t do it if I had no other choice. I’d do it to myself except I don’t have the parts. You’re the only boy I can trust. I don’t think I could do this with another boy.”

Greg gave in. “OK, we’ll try it once, but you can’t tell anybody about this.” Secretly, the idea of exposing himself to Eileen frightened him, but it also intrigued him. It was unprecedented: he had never been seen by a girl naked, yet her confidence and trust in him made him feel proud.

“I won’t. I promise!” Eileen vowed. Inside she was excited. She tried to tell herself that it was because her experiment was a success and that she now had the tool to continue it, but she knew that was the prospect of seen Greg naked that tickled her in her special spot. She was about to see her first “real” penis and it was on a boy she genuinely liked.

Greg felt funny taking down his pants and underwear for the girl. Eileen was all eyes. Even though she had seen pictures and knew what to expect, she was still excited when her first “in the flesh” penis came into view.

She urged him, “Take all your clothes off, you’ll be more comfortable.”

“Can’t you get what you want with what you see. I’m showing you everything!”

“I don’t want you tripping over your pants. Plus the shirt is in the way. I need an unobstructed view for my observations.”

Greg saw some sense in this and would up with only his shoes and socks on. Eileen accepted that.

“I’m going to need you in the flaccid state. We can do that now, or we can do that later.”

“Might as well get done whatever you’re going to do sooner than later,” he sighed.

“Well then make it go down!”

“I can’t. Turn off your machine.”

“It’s not on. Something else must be causing the erection.”

Greg looked at her up and down.

She suddenly got it, “It’s me! You’re getting hard because of me! But how? I’m not naked or anywhere near naked.”

“You are dressed provocatively enough, besides it’s not the outfit, it’s the girl. You’re good looking but you are also my friend. I probably look at you and see you prettier than you actually are.

Also, you are dressed and I’m not. For some reason the embarrassment of the situation is making me hard.”

It was Eileen’s turn to blush.

“I’m sorry,” she said.

“Don’t be. It’s just going to take more time.”

“How about we do this the other way? I’ll get you erected and while you are in that state, conduct the measurements I need when you are hard. Then we’ll deal with getting it down later.”

“OK.”

Greg was surprised when she didn’t walk to the desk where her phone was. Instead, she approached him.

She looked him straight in the face, grabbed his penis and started stroking it. “I want you to remember this,” she told him. “I’m your first, aren’t I?”

He nodded and soon he was almost as hard as when he was on the machine.

“That’s good enough,” she said, stopping her masturbation. “It looks like that’s about as big as it is going to get. Time for me to take my measurement.”

Greg could understand why she might have a ruler in her lab. It could come in handy to measure things for some sort of construction project. He could not understand why she had a tape measure: the cloth kind used for sewing. He could not think for what it would be suitable to measure other than the circumference of a penis. It did not seem to have any other practical use in the lab. He came to the conclusion that this whole incident was premeditated.

Eileen went to work measuring his organ. He was excited and leaking precum. “You’re getting my equipment wet,” she complained with mock indignity.

“I’m sorry, but I can’t help it.”

When she recorded the figures she stated, “Do you know that you are slightly bigger than most boys your age?”

“How do you know that?”

“Like I said, I read a lot. Now it is time to make your hard on go away.”

“It’s going to take a while.”

“Not if you beat it off.”

“You mean here? In front of you? While you watch?”

“Yes, I need to get a baseline of the natural condition. She wasn’t sure what she was going to learn by observing him masturbate, but she did expect it to be entertaining.

Greg didn’t know what to do or how to feel. One the one hand was the extreme embarrassment of being naked in front of a girl. More than naked, he was under her control. On the other hand, he did enjoy having erections, it was the embarrassment that they caused that annoyed him.

Then he thought more about it. He fantasized about girls when he masturbated. Now he had one right in front of him. OK, so she wasn’t naked, but she was pretty. Also, in spite of the humiliation she just put him through, he liked her.

Even without the enhancement from the application, he was at maximum hardness. He knew it was the situation that was causing it.

“Can I lay down to do this?” he asked.

“Do you have to?”

“No, but it’s most comfortable that way. Mostly I do it in bed, but I’ve done it standing in the shower, sitting at the computer and even kneeling in front of a toilet as you already know.”

“Sure, let me clear off the couch.”

“He sat down and then laid across the couch. Due to the lack of space, his legs were arched and his knees were in the air. He had to splay his legs wide open to get access to his organ. This also gave Eileen an excellent view of what he was doing.

He wrapped his fingers around the shaft of this penis and started pulling its skin over the head.

Eileen leaned in and readjusted her glasses. She had read about masturbation in its various forms and got a good description and recognized the technique he was using was colloquially known as “jerking off.” She wondered that, since he was circumcised, whether he would have enough slack in the skin to do it this way. He obviously did.

At first, he seemed to be routinely tugging at it, but as he progressed, his body became stiffer and his breathing became more irregular. At the start, he was jerking about once per second, but he was gradually increasing the tempo as time went on. For the last 30 seconds or so, his hand was almost a blur.

Then it happened: what she had only read about before and now was seeing right in front of her: an ejaculation.

For her, as an outside observer, it was an ejaculation. For Greg, it was an orgasm. He lost control over his body. His back arched. Eileen could see it. His movements were spastic, his breathing had stopped and he grunted and moaned incoherently.

He managed to keep pumping and produced jet after jet of his semen. Finally, the show was over and he slumped back with a sigh.

Eileen was gob smacked. She had expected it to be exciting, but not at all like this. She knew that it would be a long time before this fascination would wear off.

She could feel the beat of her heart in her temples and hearing it throbbing in her ears. Her inner core was in turmoil. She was on the verge of getting sick but there was a part of her that felt especially warm and tingly. She wondered if she were starting her period. No, that couldn’t be. That was supposed to be an uncomfortable feeling. This was pleasant, if not a bit messy. She could feel a wetness in her panties and she didn’t think it was urine.

Even as she reveled in what she just witnessed she thought of how she needed to connect equipment to Greg to measure his heart rate and blood pressure. Both must have bounced off the ceiling before crashing down.

Both the girl and boy sat there in silence for several moments.

Eileen was the first to recover. “Wow, that was great!

Let me get you something to clean up. Then you can get dressed.”

“What about those measurements you wanted to take?”

“We’ve done enough today. They can wait.”

As he got ready to go, she leaned over and gave him a kiss on the cheek. “I’d like very much if I could be your girlfriend. Will you be my boyfriend?”

“Uh, sure.” Greg managed to gulp out.

-=o=-

When he got home, his mom asked, “So how did it go?”

“Great! Eileen’s a really smart girl, she taught me a lot.” That was certainly true.

-=At School=-

That week at school, Greg and Eileen got along as they always did except that they both smiled a lot more when they saw each other and they would also blush just a little when they saw each other. Part of it might have been normal infatuation, but there was also the remembrance of what they did with each other. He remembered being naked before her and masturbating as she watched. She felt a mixture of embarrassment for his sake and what she put him through and the fact that she LIKED it.

For the boys, their relationship meant almost nothing aside from some childish chiding from some of the less mature boys. Greg was not a “big man on campus” so who he went out with was of little interest to the male population. Eileen was not one of the “bombshell” girls so his being with her was equally boring.

However, other girls did notice and not only did their relationship make her a minor celebrity, but Greg’s reputation with the girls also went up.

Eileen was sitting with some of the girls in her class at lunch when one of them asked, “So, you and Greg. What is it? Are you going together?”

“Well, sort of. He’s a nice boy. We’re good friends. I like him a lot.” Eileen did not want to commit herself.

“Anything romantic going on?” another girl asked. There were rumors about some other girls in the school who went “All the way” with their boyfriends.

“If there was, you wouldn’t know about it, Sharon. I’m not a kiss-and-tell kind of girl.”

The girls kept asking questions in no particular order.

“How did you get him to do it? I mean how did you get him to be your boyfriend?”

“I don’t know. I helped him with some of his school subjects and it just sort of happened. I’m sure he appreciated that.”

“So what’s in it for you?”

“He’s a nice guy. He’s not like other boys. He likes me for me. I think he’d like me even if I didn’t help him with his schoolwork. I didn’t think boys could be like that. You know – just like a girl for who she is.”

“You got that right. Other boys are so full of themselves. They are so wound up in their egos that they don’t pay attention to us girls.

“I think they’re only interested in one thing: sex!”

“I know what you mean. If you don’t have boobs, boys aren’t interested in you. Sheesh.”

“Well, Greg is not like that and I’m glad. Let’s face it girls, I don’t have a lot in that department.”

One of the girls, Carolyn said, “Don’t be so hard on yourself. Most of us girls here are at least a year older than you and we’re just starting. You’ll get there.”

Another girl asked, “Are you sure he’s not gay?”

“I don’t think so. Why would he be interested in me if he were?”

“You got a good one there, Eileen,” Sharon stated. “Remember the day all the boys got boners in the Chemistry Lab? It looked like Greg had one of the biggest. How big do you think he is?”

The other girls tried to shush her.

“Oh, come on girls. If boys judge us by how big our boobs are then it’s only fair that we judge them on how big their things are.”

Sharon was noted for being one of the bolder girls and liked to make shocking statements both to embarrass her friends and make herself feel important.

Eileen was particularly annoyed with her at the moment and shot back, “They’re called penises, Sharon. Every boy has one and I imagine that every boy would like to have information about it, like its size, secret. So even if I did know, I wouldn’t tell you or anyone else. I respect Greg too much to do that.”

Inwardly, Eileen smiled; she did know!

Sharon said, “Well, if you’re not going to do anything with him, why don’t you let me have him. I can think of a few things to do with his – PENIS – that will make him happy.” She got up and left on that note.

Carolyn comforted her. “Don’t listen to Sharon, she’s kind of crude. She doesn’t know half as much as she thinks she knows. She’s all talk. I bet she doesn’t even know what a penis looks like.

You’re a lucky girl, Eileen. I think a lot of boys could learn a thing or two from Greg.”

Eileen smiled and thought to herself, “And there are still a thing or two I could learn from Greg. If these girls only knew.”

-=The Next Experiment=-

The next time Greg arrived at Eileen’s house he saw that she had staked out markers in the backyard.

“What are those for?” he asked.

Eileen was almost bubbling with excitement. “Those are for a test I want to do with you later. First get naked. There’s so much I want to do today.”

Greg removed his clothes.

“Oh, you’re partially erected. We’ll have to fix that. I tell you what, let me turn on the app and get you hard and you can beat it down.”

Greg felt put out by the way she was ordering him around without even consulting him. He checked is anger and politely said, “Eileen, this is my body. Don’t I get a say in what you do to it.”

Eileen blushed, “Of course, you are right. I’m sorry. I’m letting my excitement get ahead of me.

There *are* a lot of things I want to do with you today and some of it has to be done when you’re flaccid.

If you are willing to masturbate to accelerate the process, I’d appreciate it.”

Greg actually laughed, “It’s OK, I know you meant no harm. I want to do these things too, but let’s do them together. You may be the smart one, but I can have ideas of my own.

To tell you the truth, I don’t think I could get it down on my own without jerking off. If I had known you wanted me soft, I would have taken care of it before I came over.”

“And deny me the opportunity to watch you do it?” she giggled back. “No, doing it here is fine. I should have told you. But there is nothing wrong. I *do* like watching you do it. You get the funniest look on your face.”

“You’re looking at my face? I thought you would be looking at … well, you know.”

“Oh, I’m interested in watching you ejaculate, what girl wouldn’t be? But your orgasm is a whole body experience; it’s more than just your penis. I want to see it all.”

“Well, then. I guess I better get to it,” Greg said, grabbing his penis.

“Do you want me to turn on the app?”

“No, I think I can do this one on my own.”

Greg laid down on the couch in a semi-reclined position. He wanted to give Eileen the best view he could of his body as he masturbated for her.

He had a very satisfying orgasm – they were always better with Eileen than without her.

“Lay down and relax,” Eileen suggested, “Recover a bit.

Let me get a wash cloth and I’ll clean you up. Would that be OK?”

“Normally, yes,” he responded, “but if you want me to stay flaccid, I better do it myself.”

Eileen now had him in the state she wanted him: relaxed and flaccid.

“We never got that flaccid measurement I wanted. There is nothing too scientific about it. A sample of one is meaningless. However I do want to compare you to other measurements made with literally thousands of men.

She took time out to do the measurement.

“So how do I stack up?” Greg asked.

“I’ll do the calculations later. Right now I want more time with you.”

She gave him a smile and then said, “Let’s go outside.”

“Like this?”

“It’s OK, with the pool we have a privacy fence. Nobody will see us. I have an experiment set up out there. There isn’t enough room to do it indoors.”

She took the naked boy by the hand and led him to the backyard to where the markers were. She led him to the one that was in the middle.

“Stand here,” she said and then added, “please.”

She told him about the experiment. “I want to know the range on the application. So what I am going to do is turn the app on and see if you get hard. Then I will turn it off, let it get soft, move you to another marker and turn the app back on.

I’m sorry I have to do this, but I don’t have a penis so I can’t do it by myself. It’s either you or another boy. I’d rather have you.”

Greg blushed but nodded his understanding and his consent.

Eileen walked away from him and put her phone on a table. “Ready?” she asked.

“Ready!” he responded.

Eileen tapped on the app. Greg felt the stirring almost immediately. In less than a minute, he was fully erected.

She gave Greg a thumbs up and said, “That was great. I’m turning it off now. We’ll have to take a break while it goes down again.”

He walked up to where he was standing and said, “Frankly, I’m surprised, I didn’t think it would go out that far. Let’s try you out at the farthest marker and see how we do there.”

They stood at the marker for a couple of minutes making small talk and she glanced down. “You seem to be ready. Are you OK?”

Greg nodded and she went back to the table. “Ready?” she cried out.

Greg responded with a thumbs up and she switched on the app again.

This time Greg just stood there. A minute went by. Finally she called out, “Anything?” Greg shook his head no. Eileen let the app run for another minute and then shut it down.

“Nothing at all?” she asked.

“I thought I felt something, but it wasn’t enough to make me hard. Maybe I was just imagining it.”

“OK. Thanks for the feedback. It’s important to me.

Let’s try you out somewhere else.”

The pair spent nearly two hours with Eileen moving Greg around like a lawn ornament from marker to marker.

Finally she was done. “Let’s go inside,” she suggested.

-=Girl Plays With Boy=-

When they got indoors, Eileen stated, “You must be really tired with all that standing around that I made you do. Do you want to rest? Can I get you something to drink.”

“I’m not really that tired, but I am very horny. You had me erected over and over. I’ve never had so many hard-ons in an entire day as I did in the time we were out there.”

“Oh my God! I’m sorry. I didn’t think of that. I don’t have a penis, so I don’t know what it’s like.”

“It’s not painful, but it is uncomfortable. There’s a kind of tension there. It’s a bit like the moment when the roller coaster falls out from underneath you except that the feeling doesn’t go away.”

“Let me take care of it. I mean that. I want to take care of it. I’m responsible for the state you are in so I should be the one to fix it.

Would it be OK if I jerk you off?”

“Are you sure?”

“I’ve watched you do it a couple of times. I think I can do it. … If you’ll let me.”

Greg smiled back, “Sure!”

Eileen moved to his side and stood partially behind him. She cradled his body into hers. She was soft and warm. Greg even remarked, “You feel good.”

She giggled and said, “And now it’s time for me to make you feel good.” She reached around with her hand, gently cupping his penis in the palm of her hand. She moved her hand up and down under the shaft. She was not even stroking it in earnest yet.

Greg moved back into her body and she tightened her embrace.

She could hear him sigh and relax in her arms. It was almost as if he had surrendered his body to hers. Slowly she curled her fingers around his shaft and started pumping.

She whispered in his ear. “Let it go. I have you. You are safe. Let me do all the work. Let me give you the pleasure you deserve.”

The couple just stood there for an unknown moment of time. He was almost as passive as an infant in the arms of its mother, she stroking his penis with both a mixture of contentment and confidence.

Her body was attuned to his and she felt the first trembling perhaps even before he did. Moments later, he started to stiffen and she hugged him tighter in response. “I have you. Let go. Enjoy my touch,” she whispered warmly in his ear.

Greg could feel his orgasm coming from a great distance. It was amplified by the fact that it was not under his control. Eileen was controlling it and at the moment he was completely under her power. He did not fight it. He surrendered to her.

He ejaculated with a force he had never felt before. Eileen could feel it. She could feel it in her hand as his semen coursed through his penis. She could feel it in his body as it spasmed with his orgasm. She could feel it in her body like a wave of warmth washing over her. She felt like she was on the verge of an orgasm herself. The two bodies were acting almost as one.

She could see the semen ejaculating out of his penis, but that was only a part of the magic she was feeling. She shuttered along with him.

And when he was spent, she let go. She wished that she could prolong the moment indefinitely.

As she became more aware of where she was and what she was doing, she guided him to the couch and laid him down gently. Then she covered his body with hers and kissed him.

Eileen had never kissed a boy before. Greg’s experience was limited to a classmate of his when they were both 10. It was a dare and there was nothing romantic about it.

Nonetheless, they both instinctively knew what to do. Eileen parted his lips with her tongue and he allowed her in. He did not have the will to resist her. She was the aggressor and he complied with every one of her advances.

After a long moment, she broke the kiss and looked at his face inches away from hers and said, “I thought we were girlfriend and boyfriend, but I think we’ve gone beyond that. At least I have. I hope you feel the same.”

Greg’s response was to grab her head and push it down to his and kiss her passionately.

-=o=-

Greg was startled when Eileen shook him awake. “We better get going. Mom’s going to be home soon and we still have to clean up your mess.”

As he was getting up she said, “That was wonderful, Greg. I never knew that a boy could make me feel so good. I am proud that I am a girl, but you made me glad that I am a girl.

I really enjoyed kissing you. I hope you feel the same.”

Greg pointed to his erection and said, “I’m up for it.” She threw the washcloth at him.

-=Test Results=-

Eileen caught up with Greg at lunchtime at school later in the week. They sat at a table by themselves. By this time most of the kids knew that they were “an item” and left them to themselves when they could.

“I still can’t get over last Saturday,” she opened.

“Me neither. I get hard every time I think about it. I think your future experiments are ruined. There is no way I am not going to have an erection around you. I’m hard now – say, that’s not your doing, is it?”

“No Greg, I turned my phone off before the last class and forgot to turn it back on.”

“Then it is you,” Greg laughed, “and not the app. You don’t need that thing to get me hard.”

“Well, I’m pretty much done with my experiments, but I am not done with my relationship with you. I’ll never use the app on you again unless you want me to.”

She took a breath and continued, “Anyway, I analyzed the results of our last experiment. It turns out that the app is more effective than I thought.

I had you erected out to a distance of about 40 feet. And that was outdoors with random noises and no walls to bounce the signal back.

In a normal room, like the chemistry lab, all I need is about 10 feet. Our workstation is in the middle of the lab and there was no boy further away than 10 feet.”

“Congratulations … so?”

“What this means is that I don’t need to use as much power. Full power runs the battery down in 30 minutes. If I only have to cover 10 feet instead of 40, I can cut the power by a factor of 16 – inverse square law, you know - which means an 8-hour battery life.

It’s a good thing that the chemistry lab is a closed room. I would have given a woody to every man and boy in that wing of the school otherwise.”

“I don’t think I could take an 8-hour erection.” Greg laughed.

“I wouldn’t do that to you, although there are some boys I think that deserve it.”

“So what are you going to do next?”

“I’m not sure. I’m thinking about designing a directional antenna. If I can do that, then I can cut the power level even more. What’s more is that, if I can get a tight enough beam, I can target one boy instead of a whole room of them.

It will be like using a sniper rifle rather than a shotgun.”

-=o=-

Greg and Eileen continued their relationship throughout the school year.

Eileen could not develop the directional antenna. It was not beyond her design capabilities, but to make it work she would have to break open her phone and she didn’t want to do that. However, she did design a box with a parabolic dish inside it. It had a slot into which she could insert her phone. It increased the efficiency of the system to where energy consumption was lower than most of the other apps on her phone.

What was even better was the beam was about an oval about three feet wide and six feet tall at 10 feet. This meant that she could target a specific boy and make him hard without affecting the boy sitting next to him.

Greg was insistent on helping her test it. “Who else are you going to test it on? I’m the only one around here with a penis.

I know how important this research is to you. If it is important to you, then it is important to me. I’d do even if it were painful, and that it certainly is not.”

He was right, He got hard almost any time around her, but he also wanted to make her happy. So, for the purposes of the test, he had her milk him before each test. It was an excuse to get her to jerk him off: an activity they both enjoyed.

When she explained the principles of how the app operated, he even suggested an experiment of his own. “You know, getting an erection and keeping an erection are two different things.”

“I didn’t know that. As I keep saying, I don’t have a penis. I’m glad you have one and are sharing it with me. What are you getting at?”

“Do you have to have the device on all the time? Would it work if you got a boy hard and then turned it off for a while and then turned it back on? It would save even more power.”

“I don’t know. Do you have a boy in mind that we could test it on?” she giggled.

“You can try it out on me, but it’s going to be frustrating for me. I’ll need you to help me take care of my problem when we’re done testing.”

“Oh, you can be sure of that, but I’ll have to do a lot of testing to figure out when to turn it off and how long to leave it off before turning it back on again. I’ll make that programmable so I can vary it and see how it works out on you.”

Eileen developed the enhancement to her application and she and Greg experimented with it with her keeping him erected for up to 30 minutes at a time by bombarding it with pulses of her “erection ray” instead of a steady stream.

“This is great,” she said when they completed their testing. “Using the power intermittently, really saves battery life. I got it programed to give a high blast initially, then go into a cycle mode at normal power. The end result is, well, I ran a test when you were not around. I turned the app on, and let my phone run. I came back 12 hours later and I still did not have a low battery warning.

Thank you for being so great about putting up with my testing. I know it was hard for you in the beginning, if you pardon my pun, but I could not have done any of this without you.

You know you don’t have to do this anymore. You don’t have to get naked for me. If we do any more testing, I know I can rely on you to tell me if you are hard.”

“Are you crazy? I love getting naked for you. I love the way you jerk me off afterwards. I can’t do it as well myself, but mostly I like the way you hold me when you do it.”

Eileen blushed, “Well, if you like it so much then we’ll do it as much as you want. I have a confession to make: I love doing it as much as you like having it done.”

Eileen eventually “went public” with the application, selling it to other girls. These girls believed that by giving the boys around them an erection, they could control them. Some girls wanted proof that it worked and didn’t take Greg’s word for it. Out of respect for him, there was no way Eileen was going to volunteer Greg as a demonstration model.

So, Eileen challenged these girls to provide a boy of their own. Most of these demonstrations were done while the boy was clothed and without his knowledge: the girl would watch his crotch as the lump developed. A few experiments were conducted on a girl’s naked boyfriend much to Eileen’s delight. She wondered what other boys looked like and compared them to Greg in her mind. Mostly the comparisons were favorable to Greg.
