Volunteering at Dilworth Private School for Girls 2
The Best Show on Earth

Prologue:

My name is Luci, and I am Sophie’s younger sister. After the success of the Advanced Interactive Health Class for junior girls, a new scheme was developed at Dilworth – an idea for a seventh grade study project. This is my story:

                                                                           *

The Dilworth school science lab smelled as you’d expect; of the lingering residue of a thousand experiments and a million chemicals. But the 22 girls weren’t there to conduct an experiment. We were there to participate in a study – a special pilot study sanctioned by the Australian Government – by the Minister of Education herself. And the Minister of Education just happened to be the sister of our principal at Dilworth Private School for Girls – Principal Tate.

Five 15 year old boys from St. Stephen’s stood at the front of the lab room. The boys looked smart in their white shirts and ties. But they looked smart and nervous, except one; Daniel Petrie. He looked pissed, big time. He glared at Principal Tate as she spoke to them; as she laid down the law. Tate told them that they must participate in the study and that they must follow all instructions, or there would be serious consequences. And she told them that they knew what she meant ... Tate had chosen the five boys carefully, as she had something on all of them. She was an expert blackmailer.

Every year, the seventh grade girls at Dilworth form groups to research and prepare study projects. The best projects are presented to the entire school and some win prizes. My study project had been my big sister Sophie’s idea. She said the study would be the best show on earth, but I wasn’t quite sure what she meant.

Sophie and I share the same birthday, but exactly one year apart. Sophie is 13 going on 14, and I’m 12 going on 13. And we have a younger sister, Bella who is 11. Our sultry Italian/Australian mother is 35 and beautiful. She produced us three girls in her early twenties, one after the other. Our father is 40, and last year he’d been hospitalized with a heart condition. At the time I’d overheard someone joke that he’d had a heart-attack after banging our hot mother non-stop for fifteen years.

So anyway, I needed an idea for my project, and Sophie suggested a study of teenage boys’ sperm.

“Luci, trust me,” she’d said. “The feminists’ will love the idea. They’re always telling us girls how life isn’t fair, that things are unequal, that it’s the boy who penetrates the girl with his penis and that he can just cum and walk away, but it’s the girl who gets pregnant, blah, blah, blah.” Sophie’s eyes sparkled as she talked. She said she wished she was back in the seventh-grade and could join in the project. “Luci, seriously, this sperm study will give more power back to us girls, like it did with Daniel volunteering in our health class.” Sophie’s eyes glazed over as she remembered.

“You should have been there Luce. It was an incredible feeling seeing him standing there butt naked with his dick sticking up and exposed for 32 junior girls to gawk at. “And it was me who made him cum – like I forced him – like he had no choice.” She whacked me on the shoulder. “But a sperm study will be even better – it will be the best show on earth, and Principal Tate and the government will love it.”

So it was arranged. For the study project, we would collect samples and scientifically study the quality of the boys’ sperm. Principal Tate decided that to get a good selection, the study would need five samples, so we’d need five boys under 16 to volunteer, with a junior girl in charge of each boy. But once word got out, more and more girls wanted to join the project. Soon it was two junior girls in charge of each boy, and then three, and finally four. So finally, we needed 20 seventh grade girls in total. We told Principal Tate we needed plenty of girls to observe the study process to make sure it was done right. And she agreed. The school allowed me to choose girls for the project from different classes, and Sophie helped me recruit the prettiest seventh-graders at Dilworth. “You need hot girls,” Sophie said. “Or the boys might not get boners and you won’t get any sperm.”

The recruiting was super-easy, as the girls were keen see naked boys and to join the hottest girl group in the seventh-grade. But to be honest, I was still the prettiest of them all. Now you may think that this sounds arrogant, but it’s true nonetheless – a fact is a fact. I am even prettier than Sophie, and she is considered a 9/10. We both have the olive complexion of our mother and usually wear our long dark hair in a ponytail at school. It’s just that the symmetry of my face is a little better than Sophie’s. Some would say it’s perfect. And ever since I can remember, my sisters and I have been told how attractive we are. Over the years, talent scouts have approached our parents about signing us up but they always said no. And a lot of boys tell me that I’m the prettiest girl they’ve ever seen – that I’m a 10/10. And boys usually get nervous around me.

I looked around the science lab. Like me, the 19 other juniors wore their bluey- green tartan uniforms with short, wide ties, black shoes and white socks. Two of girls still wore their straw hats, even though we were instructed to remove them when inside. The other two girls were 14 year old freshman; Cara and Tanja. They wore dark-blue skirts with blouses and long ties. They had taken off their blazers. The two girls had been chosen by Principal Tate to oversee our seventh-grade project. Cara had been chosen because she is Principal Tate’s niece. And Tanja is the daughter of our deputy principal. Cara is better looking than Tanja, but not by much. I’d say that Cara is about an 8/10, and Tanja a 7.5. Cara is a slim blonde and well developed for a 14 year old, with obvious large breasts that pushed out her blouse. I’m sure the boys had noticed. Tanja is a long-haired brunette. She wore black-rimmed glasses that gave her a cute, librarian look.

I looked over to Daniel Petrie. His body language was still angry, and he still glared at Principal Tate. Sophie had talked about him ever since the recent interactive health class. And I’d heard so much about his erect penis that I felt like I knew it personally. But then, I was still only 12, and I’d never seen an erect penis. Sophie had described Daniel’s in every detail; the size and shape and how it felt in her hand, with particular attention paid to his orgasm. We’d had a number of crowded sleepovers where Sophie had talked about his ejaculation to the mesmerized girls; how there had been four main spurts of cum that had shot out about three to six inches in the air; how some spurts were thicker and whiter than others, and that the last few emissions had just oozed out and down the shaft of his penis. And how his cum felt warm on her hand.

“Lucia.”

I turned at the sound of my name. Principal Tate had been talking to the junior girls, but I hadn’t heard a word.

She looked at me. “And last but not least, you, Taylor, Emily and Abigail will be partnered with Daniel, alright?”

“Yes Mrs. Tate.”

The principal paused then addressed the five boys again. They each had a sticker on their shirts with their name on it. “Remember boys, Cara and Tanja are freshman and they are in charge of this project today and have my full authority. Please do not make me come back here. And I remind you all that this is an empirical study. It is based on the scientific principles of collection and observation.

Principal Tate turned to leave. “Thank you girls. Any problems you can call me.”

“Thank you Mrs. Tate.” Cara smiled as she waited for the door to close and the footsteps to fade into silence. The five boys remained at the front of the lab room: their backs against the white board; their hands behind their backs. They shuffled their feet and looked at the floor. We 20 junior girls were bunched around the nearest science bench, about ten feet away from the boys. Cara thanked the boys for agreeing to participate is this study. She said it would help the junior girls, and in fact, all Dilworth girls with their understanding of human reproduction. And she added that this was a trial project which the government and the school would consider continuing next year if it was successful. Cara spoke quite well for a 14 year old, although she played with her blonde hair a lot, nervously putting it behind her ears. The boys remained silent.

“I guess we can get started,” she said. “But we have one question first.” Cara looked to Tanja and raised her eyebrows.

“What?” asked Tanja.

“Do you have the question?”

“You don’t know it?” Tanja took a clipboard from the bench and passed it to Cara.

“Why don’t you ask them?” Cara said.

“No way.” Tanja shook her head. “I never agreed to that. You ask them.”

Cara sighed and stepped closer to the boys. She hugged the clipboard to my chest. “Last week, in preparation for this study, you were asked to not – you know – jerk-off and stuff so that we’d get good samples today.”

A few of the junior girls sniggered. Cara continued. “So I need all of you to confirm that you haven’t done it in the last three days.”

The boys all shook their heads and mumbled to say they hadn’t done it. They couldn’t hold Cara’s eyes and looked at the floor. Except Daniel. He glared at Cara. “Kiss my ass, bitch.”

Cara smiled. “Thank you Danny. I don’t wish to kiss your ass just now, but maybe you can kiss mine later.”

Daniel said nothing.

“It’s masturbate,” Tanja said. Her voice was a loud whisper, like she didn’t want the boys to hear. But they could.

Cara turned to her. “It’s what?”

“You said jerk-off, but it’s masturbate. This is a scientific study and you should use the correct terms.”

“Oh well, excuse me,” Cara said.

“And you only asked if they jerked-off. Teenage boys have wet-dreams that they can’t control. So it’s possible that they’ve, you know, had an emission without doing it themselves.”

“An emission?” Cara said.

Tanja nodded to say, yes.

“Sorry boys,” Cara said. “Have any of you cum in the last three days.”

The boys all shook their heads to say no, they hadn’t. Except Daniel.

“It’s ejaculate,” Tanja said. “Cum is a slang term.”

“Tanja, give me a break.”

“I’m just saying,” Tanja replied.

“Kiss my ass, bitch,” said Daniel.

Cara glared at Daniel, then turned to Tanja. “Have you got those test tube things?”

“They’re in the fridge.”

“Maybe you should go get them – you think?”

“I’m not your slave,” Tanja said. “We’re both in charge here.”

“Just do it.”

Tanja retrieved a rack of test tubes and closed the fridge door. She placed the rack on the bench and passed one test tube to each of the teams of four girls in charge of each boy. The tubes felt cold and were made of glass. They had a wide funnel at the top with a test tube below with measurement markings.

“So boys, we need a sample from each of you,” Cara said. “And as Principal Tate told you, this is an empirical study which means the girls must observe your delivery into the tubes to be a hundred per cent certain we have the correct sample from each of you.” Cara smiled a mean smile, like a crocodile. “Any questions?”

Silence. The boys looked terrified. Even Daniel. The silence continued. The junior girls all looked at each other nervously. The boys shuffled their feet again.

My eyes went past the girls and out through the lab windows. It was April in Australia; Fall in the southern hemisphere, and the school grounds looked spectacular in autumn colors.

“So who wants to go first?” asked Cara.

Daniel said, “Why don’t you just give us the fucking tubes, we’ll take them home and give you the samples in the morning.”

Cara stomped over and stood in front of him. “Do you want to go first?” They eyeballed each other.

“It’s all about scientific observation,” Tanja said. “Remember all those cyclists like Lance

Armstrong who gave other people’s urine for drug tests? For this study to be accurate, we need to certain that it’s your sample.”

Cara stepped away from Daniel. She folded her arms under her breasts. It made them look bigger. She stared at the lineup of five boys. “We’ll start with Marc.”

Marc was a blonde headed boy at the left-end. All the boys were 15, but Marc was the youngest looking. He was kind of cute with an innocent face. I wondered what Principal Tate had on him, but it must be something significant. Cara gestured for the four juniors in charge of Marc to come forward. They stood in front of him with the test tube ready. The four girls looked even more innocent that Marc. A few of the junior girls had turned 13, but most were still 12.

“You’ll need to take down your pants.” Cara said.

Marc shook his head. He looked too terrified to speak.

Cara reached forward and began to unbuckle his belt. Marc doubled over. Cara tried to yank his pants down. Marc dropped to his knees and hunched up.

“You have to take them off!” Cara tried to pull him to his feet. But he stayed on his knees. Cara whacked him on the head. “Take them off!”

“Leave him alone you bitch!” Daniel shouted.

“Don’t hit him,” Tanja said.

I couldn’t stand it any longer. I stepped over and knelt beside Marc. “Come with me.” I grabbed his arm and dragged him over to a storeroom and opened the door.

“What the hell are you doing?” Cara shouted.

“Just give me a minute.”

My hand pushed the door closed and I hit the light switch. The florescent lights plinked, then the small rectangular room lit up nice and bright. Storage racks and shelving lined the walls. I pulled Marc down to the end of the room and pushed him up against a corner. “Marc, you’re going to have to do it.” His body shook. He just stared at me. I gave him my best little smile. “So what do you think of me?”

He stammered, “You’re the prettiest girl I’ve ever seen.”

The door opened and the four girls appeared. “What’s happening?”

“Tell Cara one more minute and then you can come in.”

The door closed. I turned to Marc. “Guess what?”

“What?”

“I’m taking down your pants, and you’re going to let me.” I undid his belt, buttons and zipper and pulled his pants to his knees. He didn’t resist, so I yanked down his boxers. His penis was limp so I pressed my body against his and kissed him. He kissed me back and I soon felt his penis stiffening.

                                                                                          *

Now I’m still only 12, but you may be surprised to know I’ve kissed boys before. In fact, I’ve been kissing Ben for the last month. He’s the good looking 17 year old son of one of our neighbors. We meet up at night in the back garden where our properties join up. It’s just open mouth French kissing that sometimes goes on for 20 minutes. Sophie and I used to flirt with Ben, but then after her experience with Daniel in the interactive health class, Sophie began kissing him. And then she started jerking him off. She said she really likes watching him cum. And a few weeks ago she started sucking his cock. Sophie says she enjoys sucking it, and Ben loves cumming in her mouth, so it’s a good arrangement.

But the truth is, I only began kissing Ben by chance. One night Sophie couldn’t make her rendezvous, so I went to tell Ben and he grabbed me and kissed me. He told me that I’m the most gorgeous girl ever. So now Sophie and I take turns to meet up with him at the back fence. Ben wants to do a lot more with me than just kissing, but I won’t let him. He always presses against me so I can feel his erection. Lately I’ve allowed him to finger me, and sometimes he tries to get a second finger inside, but my little pussy is too tight. And he always asks me to touch his penis, but I always say no. The last time we kissed he rubbed against me and came in his pants. And that’s when I left and went home.

                                                                           *

I broke the kiss with Marc and looked down at my first erect penis. It had grown bigger than

I’d expected from the limp size – about five inches long now and quite thick. It stuck up on about a 45 degree elevation.

The door opened again. Cara said, “What the hell’s going on?”

“Marc’s ready. Tell the girls to bring the test tube.” The four girls joined me and we crowded around Marc in the back corner.

Cara said, “Hurry up,” as she left and closed the door. The girls’ eyes dropped straight down to Marc’s erection. I wondered if they’d seen a real one before. Marc instinctively put his hands in front of it.

I said, “Marc, you either do it in here, or you do it out there.”

He stared at me with a terrified face. He was about to jerk-off for five very pretty junior school girls. I forced his hands away to reveal his stiff cock again. “Here, let me help you.” I put my left thumb and finger around the shaft and put his right hand around mine. My hand began jerking back and forth and I soon felt him helping me.

About 20 silent seconds went by. I said, “Tell me when it’s going to come out.” Marc made a groaning sound and I knew it wasn’t far away. “Is it coming?” Marc nodded his head and groaned again. We kept jerking back and forth. My little finger banged against his warm balls.

I said, “Hold it closer,” just as the first white spurt came out. It hit the inside of test tube funnel. And then another spurt, and another. About five seconds passed before it stopped coming out.

The door opened and Cara entered. She shouted, “Have you finished? You’re not even supposed to be in here.”

“We’re done,” I said.

“Well, come back out then.”

Marc pulled up his boxers and pants and we walked back out to the lab room. Cara snatched the test tube and held it up. Some of Marc’s semen had collected in the bottom of the tube. The rest slowly ran down the glass. “Did you see it coming out?”

The four girls nodded to say ‘yes’, they had watched Marc cum into the test tube.

“I saw it too,” I added.

“Luci, you’re partnered with Daniel and you shouldn’t have been helping with Marc.”

“Yes, but Luci did get Marc’s sample,” Tanja said. “Which is more than you did.” Tanja took the test tube from Cara, stuck a label on it and put it in the rack.

“Well, did you measure his dick?” Cara’s had her hands on her hips.

I went back over and stood with in front of Daniel.

“Penis,” Tanja said. “Not dick.” She pushed her black framed glasses firmly to her nose and gave Cara a little smile.

“Whatever,” Cara said.

“You never said we had to measure it,” one of the juniors said.

“Well, you do,” Cara replied. “And you have to time how long it takes to go soft again. It’s all part of the study.”

“Flaccid,” Tanja said. “A penis in its normal state is called flaccid, not soft.”

“Just shut up!” Cara’s voice echoed around the lab.

“And when it’s fully erect it’s called a phallus,” Tanja added.

“No it’s not,” Cara said.

“Yeah, it is,” Tanja countered.

“No,” Cara said. “Phallus and penis mean the same thing.” She stepped over to Marc. “The girls have to measure it and time how long it takes to go soft again.”

Marc’s white shirt hang out over his pants. Cara lifted the shirt up, undid his belt, buttons and zipper. Marc put up some resistance, but Cara was determined. Soon his pants and boxers were around his knees. Marc covered his penis with his shirt and hands. Cara slapped his butt cheek. It sounded painful. “The girls have to see it!”

“Don’t hit him you bitch,” Daniel said.

“Don’t worry Dan – your turn’s coming.”

Cara forced Marc’s hands away. She undid the lower buttons and spread his shirt around his penis. She stood back. His erection hadn’t gone down at all, and now it stuck out into the lab room for all the juniors to see. The girls stared in amazement and I could feel the tension in the room rising. Marc’s face went bright red. He stared at the floor. I glanced around the lab. Every girl’s eyes were glued to Marc’s erection. And his balls. Some of the girls whispered to each other, then giggled as they stared at his stiff cock again. Cara issued measuring instructions. The girls stepped forward and used a tape to measure his length and girth. Tanja wrote the numbers down. “We should measure their phalluses before ejaculation because they can deflate quite quickly afterwards.”

Cara gave Tanja a sarcastic smile. “It’s so great that you’re Dilworth’s resident penis expert.”

“I’m just saying.”

Cara pointed to Marc. “His cock still looks fully hard to me.”

“You mean his penis looks fully erect,” Tanja said. “And how can you be sure?”

Cara gestured with her hand. “Girls, Luci – come here please.” I stepped over and stood near Marc with the other four girls. “Is it still fully hard or has it gone down.”

We focused on Marc’s erection. It looked the same as when he’d cum into the test tube. Some semen still oozed from the hole. A white gooey drop hung from the head, threatening to drip onto the floor. We all agreed it was still the same size.

Cara looked at Marc. “Is your penis fully erect?”

Marc’s eyes remained on the floor. He couldn’t look at Cara. He mumbled something.

“What was that?” Cara leaned in. Marc mumbled again. Cara stepped back. “He said it’s as big as it gets. So there.”

Tanja cleaned her black framed glasses then put them back on. “But we should still measure their phalluses before ejaculation. Just to be sure.”

One of the juniors spoke up. “I just Googled phallus and the dictionary says it means the same as penis, but it also means an image or symbol of an erect penis.”

“So there,” Cara said. “Phallus and penis are the same. So I’m right, you’re wrong. Eat that.”

“Why don’t you girls just fuck off and leave us alone,” Daniel said.

Cara stepped over to Daniel. “Happy 16th birthday for tomorrow Danny. What a shame; one more day and you’d be too old to volunteer.”

“Fuck off.”

“That’s not very nice Danny.”

“I’ve done this bullshit already – in that fucking interactive health class.”

“Yes – we heard all about it. But you ejaculated your semen all over the classroom floor Danny. And you had to get down on your hands and knees to clean it up, didn’t you?” Cara smiled like a crocodile again. “But this time we need you to cum in a test tube.”

“Fuck off.”

“That’s not very nice. I might tell Principal Tate that you’re being abusive and uncooperative. And she might tell her sister, the Minister of Education. And gee, you might lose your scholarship Dan. Wouldn’t that be a shame?”

Daniel said nothing more.

There was a moment of silence. Cara breathed deeply and her breasts went up and down. She stood in front of the line-up of boys. “So far we’ve only got one sample and if we don’t hurry up we’ll run out of time.”

The three boys in the middle had obvious bulges in the front of his pants. All the girls had noticed, including Cara. “You three can all go together.” She turned to Daniel who didn’t have a bulge. “But we’ll save you for last.”

Daniel stared straight ahead and said nothing.

“Can we do it in the storeroom?” one of middle boys asked.

“No,” Cara said. “You have to do it out here. So you can all take your pants down. And don’t dilly-dally.” She turned to the juniors. “Girls, you can come forward with the test tubes.”

My eyes looked at Marc’s exposed erection and then at the three middle boys’ bulges. I wondered how their penises would compare to Marc’s. We were about to find out and the excitement and tension in the lab room had increased again. The junior girls positioned themselves for a good view.

My mind went back to the last few summer months. I’d seen a few boys with bulges in their swim shorts and underwear and knew they’d had erections. At the time I’d wondered what the boys would look like naked, and now I knew. Some of boys’ erections had been caused by me, and some by Sophie.

Cara was having trouble getting the middle three boys to drop their pants. But a few more threats and spanks on butt cheeks and it was done. Now four 15 year old boys stood before us; their heads down, their faces red, their erect penises and testicles fully exposed for the viewing pleasure of 20 Dilworth junior girls. The erections varied in size and shape as you’d expect. One stood up on a 45 degree elevation similar to Marc’s. Another was just above horizontal, and the last one was nearly vertical against the boy’s stomach.

Cara agreed with Tanja that the girls should measure before ejaculation. There was only one measuring tape, so Lexi, Holly, Abigail and Mia were up first as they were in charge of Josh who stood next to Marc. Lexi and Holly still wore their straw hats. The girls are known as the twins, but they’re not really twins, they just look similar and are always together. And if I was the hottest girl there, then Lexi and Holly were the cutest, with pretty faces and long brown hair in pigtails and ribbons.

The four girls couldn’t agree as to who would do the measuring. They began laughing and acting up. Cara told them that this was a serious study, and they had to act maturely. The girls performed paper-rock-scissors to decide and Holly lost, so she was the measurer.

Tanja said, “Don’t forget this is a scientific study. We have to make sure the boys are fully erect before we measure.”

The room went quiet for a few seconds, with just a few whispers.

“Holly,” Cara said. “You’ll have to ask.” Now the room went dead silent.

Josh’s erection was the one on a similar 45 degree elevation to Marc’s. Holly nervously played with her pigtails. She went to ask Josh but burst out laughing as she opened her mouth. Then all the juniors laughed with her.

“Come on Holly,” Tanja said. “Be serious. We’re running out of time.”

More silence as Holly built up her courage again. Then she asked in a sweet voice, “Josh, is your penis fully erect?” She doubled over giggling again and more laughter filled the lab room.

I felt sorry for Josh. The combined focus of 20 junior girls’ eyes on his stiff cock must have been unbearable. He nodded to say ‘yes’ to Holly’s question. So Holly stepped forward and measured his length and girth. Lexi kept whispering and pushing her from behind the whole time and they had more fits of giggling. Josh’s face went even redder during the measuring – if that were possible.

Then Holly’s straw hat came off. It fell straight down and caught on Josh’s erection. It hung there, as if on a clothes hook.

Now even more laughter filled the lab room. It went on for about ten seconds. Some girls doubled over as they pointed and gasped for air. Josh looked devastated; his face now redder than a beetroot.

But soon the laughter was over. The other two middle boys were asked the humiliating question: is your penis fully erect? They both said ‘yes’ so their erections were measured. Now all three middle boys began masturbating together, and I wondered which boy would cum first. The assigned junior girls stood in front of them with the test tubes ready, patiently watching and waiting for their ejaculations.

                                                                                          *

Now like I said, over the summer I saw a few boys with penis bulges. Some were at our swimming pool at home, and some others were in an old windmill on a farm. The ones at home were caused by Sophie – mostly, with me and young Bella helping out. We invited a bunch of boys around for a swim. Sophie had tampered with her one piece swimsuit and removed some padding in just the right place. Her one-piece was a light blue color with Hawaiian flowers on it. The removal of the padding made her black bush visible, with a nice little camel toe for the boys to stare at. And stare they did. They couldn’t get enough of it, especially when she lay on her towel with her legs open. We asked the boys to carry us in the pool on their shoulders, and they loved having our 11, 12 and 13 year old pussies pressing against their necks. There were six boys, and without exception, they all got erections as they carried us.

                                                                           *

The sound of groaning snapped me back to the lab room. Two of the middle boys ejaculated into the test tubes, almost at the same time. The test tubes were labelled by Tanja and placed in the rack. One boy tried to pull up his pants. He complained that he’d provided his sperm sample and should be allowed to go. But Cara spanked his butt and told him the girls had to monitor his erection right to the end. So the boy continued standing there with his head down and his manhood fully exposed. And twenty 12 and 13 year old junior girls continued enjoying the sight of his still stiff cock and balls. Josh hadn’t cum yet and continued jerking back and forth; his hand a blur of movement. Daniel still had an angry look on his face. He knew he was up next, and he was pissed off about it.

                                                                           *

Now the other penis bulges I saw were caused by me – definitely. Over the summer break my family stayed at a vacation house in a small seaside town. We met up with other kids in the area – some who we knew from staying there before. A group of us had arranged to go ride our bikes in the countryside, but on the day, Sophie and Bella and the other girls didn’t come, and it ended up being just me and four boys. At the time I was just over 12 and a half, and yes, I am a super-pretty girl and I knew the four boys really liked me. Two of the boys were 12 and two were 13 and they all stared and talked about me a lot, which I complained about of course, but secretly enjoyed. The summer sun had darkened my olive skin and my big brown eyes are mesmerizing – or so I’m told.

The weather was hot, and I dressed in a provocative manner to give the boys a treat. I chose a very short skirt that would regularly reveal my favorite panties: skimpy light-yellow cotton briefs with pink hearts on them. And the small white tank top I wore was too tight because it belonged to Bella. But I borrowed it because that’s the look I wanted.

All last year and up until the start of summer, my breasts were just puffy mounds, but at the beginning of summer they’d begun to grow suddenly, and back then, at just over 12 and a half, my breasts had become much more prominent with large pink nipples. Mom had brought me some bras but of course that day I didn’t wear one and Bella’s white tank top allowed me to showcase them nicely. I checked in the mirror before I left the house. The mounds of my breasts pushed out the tank top noticeably, and my large pink nipples were clearly visible through the thin cotton. But of course, I was just an innocent young girl with my long dark hair in a ponytail and was totally unaware of the sexual tension my body would cause. At least, that’s what the boys and any men who happened to see me would think.

                                                                                          *

Josh ejaculated with a groan and a shout. I watched his semen spurt and ooze into the test tube because the four girls stood on the far side of him, leaving my field of vision unobstructed. Josh was about 15 feet from me, but even from a distance his ejaculation seemed to be thicker and whiter and more voluminous than the other boys. His test tube was labelled and racked, and now it was Daniel’s turn. Cara told him to take down his pants, but Daniel remained motionless. She repeated the order over and over, but to no effect.

Now Cara gave me an order, so I stepped forward and unbuckled Daniel’s belt, unbuttoned his pants and pulled them down to his knees. Cara issued another order, and I pulled his boxers down. Daniel’s limp penis hung there, long and thick. But then, I already knew what his limp penis looked like, because I’d seen it before.

Last year I attended Daniel’s sister’s 11th birthday party. Daniel’s older cousin had played a trick and pulled down Daniel’s swim shorts while he held a tray of glasses. There were about 15 eleven year old girls watching, and we all enjoyed the sight of Daniel’s cock and balls as we laughed and shrieked in shock. The image stayed in my mind and still does, and it was that night that I had first started masturbating. When I went to bed I took a teddy bear with long silky fur and placed it between my legs as I lay on my stomach. I rubbed the bear up and down as I ground and humped on it. I still remember the wonderful feelings and sensations that surged through my body for the first time. And all the while, I had image of Daniel’s penis in my mind.

I stepped away from Daniel and glanced around the lab. Every girl’s eyes were on the large limp dick that hung there, motionless. There was a moment of silence again, then an innocent junior girl asked, “Is there something wrong with it?” Laughter burst into the lab from every girl’s mouth, but none of the boys laughed, especially not Daniel. He just stared straight ahead, and tried to remain calm, but I could tell his was humiliated – big time. His body trembled.

“No,” Cara said. “I don’t think there’s anything wrong with it. But let’s find out.” Cara removed her tie and began unbuttoning her blouse.

Tanja said, “What are you doing?”

Cara didn’t answer. She took off her blouse and stood there in the white bra that held her big breasts in place.

“Cara,” Tanja said. “This is a scientific study. I don’t think you should be doing this.”

Cara ignored Tanja and stood in front of Daniel. He was trying not to look, but couldn’t help himself. Cara reached behind her back and unclipped her bra strap. “This is scientific, because for every action ...” She let her bra fall off and revealed her large naked breasts. They were a nice natural shape with big nipples. I wanted to touch them myself. We all watched in awe as Daniel’s limp penis began to jerk as it filled with blood. Cara smiled. “Like Albert Einstein said, for every action, there is an opposite and equal reaction – or something like that.” Daniel closed his eyes. He looked furious and embarrassed that he couldn’t control himself.

I was the closet girl to Daniel, and I couldn’t take my eyes off his growing cock. It jerked and expanded, and soon stood up on about a 60 degree elevation. It was an impressive erection, and now I knew what Sophie had been talking about. And Daniel’s balls were bigger than the other boys.

“Geez Danny,” Cara said, her eyes on his stiff dick. “You didn’t even put up a fight.”

The girls kept talking, but I didn’t pay much attention. Someone complained that now all the boys were fully hard again, and that the timing of their erections back to a flaccid state was a waste of time. Then Tanja corrected Cara, telling her the quote she used was from Isaac Newton, not Einstein.

But my eyes stayed glued to Daniel’s cock. Sophie had told me that it was six inches long. It had a slight bend and the head was a little larger than the shaft. Drops of clear fluid appeared from the hole and ran down the front of the shaft. I knew it was pre-cum, because Sophie had told me all about the natural lubrication. I tried to imagine what it would be like to have him pump his penis in and out of my little pussy and cum inside me. Maybe I’d find out someday.

I stood off to the side of Daniel, about five feet away. And I didn’t know why, but I suddenly felt the need to look up. Daniel intense eyes met mine, and I knew he had been watching me staring at his cock – watching helplessly, that is. Sophie had spoken about catching his eye as she’d ogled his naked body and the strange feeling it had given her. A new feeling that she enjoyed. And now I was enjoying it too. I couldn’t describe the feeling, but the fact that I was fully dressed in my school uniform, and his pants were at his knees with his erect penis and testicles were fully exposed gave me a tingling sensation.

I held Daniel’s eyes for a few more seconds, then smiled and deliberately lowered my eyes to his erection again. I just loved knowing that he was watching me stare, and there was nothing he could do about it.

“Well I know one thing for sure,” Cara said. “Daniel gets the prize for the biggest balls.”

There was more laughter in the lab room as all eyes focused on Daniel’s testicles. Then Cara said that time was running out and that we needed to get Daniel’s sample. The other three girls whispered to me that they’d hold the test tube if I did the measuring.

So we stood in front of him. Daniel stared straight ahead, trying to pretend we didn’t exist. I held the measuring tape and asked in my sweetest voice, “Daniel – is your penis fully erect?”

But Daniel didn’t flinch. He said nothing. So I asked him again. And he said nothing, again.

“You’re not being very helpful,” Cara said.

Daniel didn’t respond.

“Tanja, what do you think?” Cara asked. She’d put her bra and blouse back on, but hadn’t done up the buttons.

“It looks pretty hard to me.”

“Is ‘pretty hard’ a scientific term?” Cara asked.

“Whatever,” Tanja said.

Cara turned to the other junior. “Girls – do you think Daniel’s penis is fully erect?”

The girls all nodded to say ‘yes’.

So I measured. I got some pre-cum on the tape as I wrapped it around the thickest part of the shaft. Daniel refused to masturbate, so Tanja gave me some medical gloves and told me to do it for him. I put on the gloves and stepped to Daniel’s side. My left hand pulled his erection down on an angle just above horizontal, and I started jerking back and forth. His foreskin moved up halfway over the head each time I pulled forward.

                                                                                          *

As I was saying, the four boys and I rode our bikes out into the countryside to Beacon’s Hill, about three miles from town. The boys followed my every move like puppy dogs. Whenever we stopped our bikes I made sure one of my feet was high on a pedal so my panties were on show. And I pretended not to notice when the boys positioned themselves to get an eyeful of light-yellow cotton and pink hearts. And of course my breasts and nipples were on permanent display through the thin white cotton, and I knew the boys were loving the view.

On the way back we trespassed on a farm and entered an old disused windmill. It had a musty smell that I loved. A vertical wooden ladder rose up to some kind of landing above. I decided to climb up first so the boys could check out my butt and panties from below – which they did of course.

Up on the landing we lay in a circle on the old wooden floor and I asked the boys if they wanted to play truth or dare. They were unsure what to do or say, so I took the lead. I asked them if they got hard-ons, and they had to tell me the truth. The boys were embarrassed to answer, but they all said they got erections all the time. But none of them had had an ejaculation yet.

I asked, “Who’s the prettiest girl you’ve ever met?” But of course I knew the answer, and the four boys each told me that I was the prettiest girl they’d ever met. And I pretended to be surprised. Then I asked them if they’d ever seen a real girl naked. One of them said that he’d seen a 14 year old girl naked. He’d been in the living room of a friend’s house when his friend’s sister had walked in. She hadn’t been expecting them to be there. She’d just had a shower and was looking for clothes their mother had ironed. He said he liked seeing her boobs and bush. Two other boys had seen their sisters naked, but only when the girls were seven or eight.

The musty smell in the windmill made me feel intoxicated and excited. I asked the boys if they wanted to see me naked. They didn’t answer at first, so I told that it would have to be a secret, a super-secret, and they couldn’t tell anyone, and that they had to blood-swear to silence. One of the boys had a Swiss Army knife and we all nicked out fingers and touched our hands together with smeared blood.

So I stood up in my white tank top and short skirt. I told the boys to stand up and take off their shorts – but they could leave their underwear on. The boys obeyed, and I saw the penis bulges I told you about earlier. I didn’t know how big 12 and 13 year old boys penises were, but each boy had an obvious erection. Then I told them to kneel down, and again, they obeyed. Then I turned around and lifted up my short skirt to expose my butt and panties. Then I slowly pulled my panties down and bent forward. I knew my slit would be fully exposed, but I wanted the boys to see it. I stepped out of my panties and stood up straight again.

Next, my hands pulled my tank top up over my head and I dropped it on the floor. Now all I was wearing was my short skirt, and the boys had a view of my bare back. My fingers removed the tie that held my ponytail, and my long dark hair fell on my bare back. Next, my hands lifted my skirt up again to expose my bare butt cheeks. Cute butt cheeks that is, or so I’m told. I stood there for about thirty seconds and breathed in the sweet, musty air. The boys remained dead quiet as I turned around. I enjoyed watching their faces as they ogled my young boobs.

The boys knelt in front of me with wide eyes and open mouths. They stared up at me like I was some kind of nymphet goddess. My short skirt hung down just enough and I knew they couldn’t quite see my pussy. So I placed my feet a little further apart and slowly lifted up my skirt. Their eyes dropped straight down and they gazed in wonder. At just over twelve-and-a-half I had a kind of a bush. It was a nice small triangular shape, but with just a light covering of black hair. No doubt is would be a fuller black bush like Sophie’s in another year or so. But of course, the little lips of my sweet young vulva were on full display for the boys to stare at. And stare they did. They couldn’t believe their eyes. I felt powerful standing there, like a warrior princess, and I allowed the boys about a minute of viewing pleasure before I put my clothes back on. Then we left the windmill and rode back to town, and I wondered what would happen next summer.

                                                                           *

Daniel moaned and his body moved. He was close to ejaculation. Cara had been taunting him, saying she knew he was trying to hold back, but that he needn’t bother as I would keep going until we made him cum. Cara had told me to jerk faster and faster, and my hand was a blur.

Daniel groaned again and I watched his semen spurt into the test tube as I pulled his cock back and forth. And the spurts kept on coming. He shot out the most of any of the boys – nice and thick and white.

And then it was done. We had five sperm samples from five 15 year old boys. I stepped away from Daniel and checked out the line-up again. One boy’s erection had subsided, but the rest looked fully erect as before. I wondered what it would be like to suck all five penises and have each boy cum in my mouth.

Cara thanked the boys for volunteering and said we would let them know the results of the study in due course. Then she hesitated, and made them stand there for a moment longer, fully exposed for our viewing pleasure. “Okay,” she said. “We’re done.”

The boys all pulled up them pants and scampered from the lab as quickly as they could. My phone had a message from Sophie to meet her in a room near the school auditorium. When I got there she was sitting at a table with some other girls watching a video on a laptop.

“Check it out Luce,” she said.

The video was from the lab room I’d just left. It showed the five boys lined up at the front. Luci fast forwarded and stopped at the point where Josh was jerking off and cumming into the test tube. The high definition camera had zoomed in and clearly showed his semen spurting out.

“Holy crap!” I said. “You had cameras in there?”

Sophie pointed to one of her friends. “Morgan’s the techie. She set up the little cameras on the ceiling.”

I shook my head. “Seriously?”

Sophie smiled. “I told you it would be the best show on earth.”
