Puberty Lessons

It was around 4 o'clock in the afternoon and childhood friends Boruto and Sarada were walking home after school like they usually would do. Normally, Boruto would drop off Sarada at her house which was on the way to his own but because of a certain proposition, Boruto will be taking a visit to Sarada's house.

"So, what do you say about my proposal?" Boruto asked Sarada as they were walking. Sarada fixed her glasses before turning to look at Boruto.

"You're a pervert." Sarada retorted.

"But like I said, I'm just really curious. We've started the topic about puberty and there's no better way to know more about it than learning it in real life. Aren't you curious too?"

"I'm n-not." she tried to deny but Boruto could easily tell she was lying.

"Yeah you are. You just stuttered."

"No I did not!"

"Yeah you did. Come on. Everyone else is curious. And besides, it's just between the two of us. No one else will find out." he said as he gave a wink.

"Boruto, you're a real perv. I can't believe you're asking a girl this thing. You know, if you want you can just search it on the internet."

"Yeah I know, but it wouldn't be as informational. Besides, it's not like we haven't seen each other naked before." Boruto reminded her.

"Bo-boruto! Don't say stuff like that out here. Someone might hear you. I'll die of embarrassment if someone finds out about that."

"We were just kids and my mom gave us a bath along with Hima. It's not like I know about this stuff before. Now because of that lesson a while ago, I'm really, really curious. Come on, you gotta help me out. I know you're curious too." he pleaded.

Sarada didn't give an answer and continued to just walk. Even though she was denying, deep down she was truly curious too. But she also didn't want to have Boruto think she was a perv. She wasn't. She's never even considered doing something like this before until Boruto proposed it during lunch. She knew it would be very embarrassing to participate in what he was suggesting, but then it would be for him too so that would be equal right?

She was too deep in thought that she didn't realize they were already in front of her house.

"Hey, where are you going?" Boruto called out to the still walking Sarada. "Your house is over here."

Sarada turned back and indeed Boruto was right. She walked passed it. She quickly walked back to where Boruto was standing.

"You seem to be thinking hard. So, what do you say?" Boruto asked again, this time really hoping she'd say yes. Sarada tried to look conflicted but she already decided on what her response would be.

"Fine." she gave out a defeated sigh but deep down her heart was pounding crazy.

They made their way inside her house, leaving their shoes on the rack outside and wore indoor slippers. Sakura's father was usually away, and her mother worked as an emergency doctor. She wouldn't be home until her shift was over and usually that was past 6 PM. That would mean they would have the house all to themselves for the next 2 or so hours.

And so now, the two were inside Sarada's bedroom, looking at each other, waiting for one of them to make the first move.

"S-so, this is your idea. What are we gonna do?" Sarada asked shyly, as her cheeks were tinted red. She still couldn't believe she agreed to this but now there was almost no turning back. Her curiosity was preventing her.

"Well, we just study what our teacher talked about in class." Boruto answered, nervously. Even if he was the one who proposed it, now that they were standing face to face inside her room, the butterflies in his stomach were starting to go wild. "Uhm, do you have them yet?"

"Wh-what?"

"You know, the thing that girls get in puberty."

"You have to be specific."

"The blood. That once in a month thing."

"D-do I really have to answer?"

"Well you agreed to it. Besides, I'll answer any of your questions too."

"Ye-yes. I have it."

"Now?"

"No-not now. Like, two weeks ago." she said in almost a whisper.

"Since when?"

"Last year."

"Oh. Must be gross right?" Boruto chuckled.

"Did you ask me that just to tease me?"

"No. I'm just curious."

"Well, what about you? Do you… already have hair down there?" Sarada asked this time, trying to keep a straight face.

"A bit. What about you?"

"Yes, a bit too."

"Well we definitely didn't have them last time we took a bath together."

"That was a long time ago."

"What about up there? Are you already getting boobs?"

"B-Boruto!" she squeaked his name in shock as she cross her arms around her chest to cover it.

"What? I thought we can ask each other any question."

"F-fine. Yes, they're starting to show."

"May I see them?" Boruto asked innocently.

"Wh-what?! N-no!" came the immediate refusal from Sarada.

"Why not? It's just the two of us. And I've seen you naked before."

"Like I told you, that was when we were kids. I didn't have them yet."

"They're still the same part I saw before, just getting bigger I suppose. But like I said, I'm just curious."

"Well, then you go first."

"Me? But I'm a guy. I don't have boobs to show."

"Well it's your idea to get naked and show each other our private parts."

"Fine, fine." Boruto agreed to Sarada's point and took off his shirt, showing her his bare upper body. It wasn't that much to look at though. "But like I told you, it's not like something you haven't seen before. I don't grow boobs and I don't have chest hair. So, will you show me your boobs now?"

Sarada pouted. It was unfair. Boys' upper body weren't sexual in nature, and here Boruto was asking her to show him her upper body. She was fidgeting in place and undecided on what to do next. But Boruto made his way closer to her.

"Come on. It will be both of us naked sooner or later. Or do you want me to take it off for you?" Boruto teased.

"No. I'll… I'll do it myself, if that's what you want, you big pervert." And Sarada did as she said. She took a deep breath before taking off her shirt which revealed her upper body in just her bra.

"Oh! So you're already wearing a bra." Boruto said in wonder.

"Because I'm already developing. I started using it 6 months ago." she explained. It was still more of a baby-bra than a full sized one.

"Take it off. I wanna see your boobs." Boruto requested, failing to hide the excitement in his voice.

"Alright. Why are you so eager, you perv?" Sarada said with a roll of her eyes. Earlier she was unsure about doing any of this, and then when she took her shirt off she felt embarrassed. But now that she was about to take off her bra, a different feeling swelled up inside her.

Thrill.

She reached back with both hands and unstrapped her bra. Then she let it fall to the floor, revealing her breasts all for Boruto to see. The boy in front of him had his eyes glued on her chest and it made her feel a bit conscious. She was still small in that department, while her other classmates were early bloomers.

"So, are you gonna stare at them all day or what?"

"S-sorry. It's just my first time seeing one in real life, sans my mom when I was baby." he said. He could see the beginning shape of the breasts but it wasn't what one would really call boobs yet. His own mother, on the other hand had a very huge rack.

"Well, you've seen them so I may get dressed already, right?"

"Wait. I want to touch them, please?"

"T-touch them? N-no." she refused.

"But we're supposed to study right? And besides, you've shown them already, might as well let me feel them for a bit."

"Grrr. You're such a pervert. Fine. But after this you'll let me 'study' you too."

"All okay with me." Boruto smirked and got even closer to Sarada. Carefully he brought his shaking hands and cupped both her boobs. He could feel the small soft protrusion from her chest, like what he expected. It made his fingers tingle as he was finally touching a girls boobs for the first time.

"Awesome." he whispered under his breath. He began to caress them and his thumbs flicked on her nipples, which made Sarada moan out.

"Does it feel good?" he asked. Sarada cheeks were a deep red as she realized that she just let out a sultry moan because of the touch of a boy, her childhood friend nonetheless. It felt good, a new sensation she's never felt before. If she didn't have any sense of embarrassment, she would have let Boruto touch her more. But she wasn't gonna say that out loud or else die from humiliation. She grabbed both of Boruto's arms and pushed them down. She knew she might ask him to do more if he continued for longer.

"Okay, you've felt them. Happy now?"

"Yeah. I suppose."

"So, it's my turn now, right?" she clarified.

"Yeah. Your turn."

"Okay. Show me your penis then." she said quickly and in almost a whisper.

"Wait, what was that?" asked Boruto, who pretended to not hear her.

"You heard me."

"No. You spoke too fast. What do you want me to do?" he asked again, feigning ignorance. Sarada could clearly see in his expression he was teasing her. Making her say it again just so he could hear it again.

"Ughh! Show me your penis." she repeated, loudly and clearly this time. Boruto smirked at her.

"Okay then, since you wanna see it that much."

"Hey, I don't wan-" She was about to deny but Boruto had brought down his pants along with his underwear and out sprung his semi-erect dick which stopped Sarada as she took in the sight.

There it was. A penis. Right in front of her. Just as Boruto stared at her breasts, she couldn't take her eyes off it. She's seen Boruto's penis before but that was when they were kids and she didn't think much about it. Plus, it was way small back then. This one was a bit bigger than what she's seen before. And like Boruto said, he was starting to get hair down there. They were still short and few, and they were blond just like the hair on his head.

"It's not that big yet but hey, I'm just starting puberty you know." Boruto immediately said. He feared Sarada might tease him by saying it was small. His voice brought Sarada back to the real world and she finally took her eyes off it and looked up to face Boruto.

"Well, it doesn't appear to be like what our teacher told us on how long it should be." she commented, just as Boruto predicted she would. "They said the average was around 5 and a half inches, yours is like around 4 and thin."

"Sorry it isn't what you expected." Boruto pouted at her. "Like I said, it's not yet fully grown. So don't worry about its size okay. I was not commenting about your boobs being small a while ago was I?"

"W-well you just did, baka." Sarada threw back, covering her boobs with her hands at Boruto's remark.

"Okay, okay. Let's just forget about that. So, what do you wanna do, besides stare at it?"

"Huh?"

"You let me touch your boobs, so I'll let you explore it. I'm sure you're also curious about something you don't have right?"

"Well, I am a bit curious."

"Have a look at it then. I'll sit here on the bed. But then afterwards, you let me see your pussy."

"Boruto! Don't say that word. It sounds so dirty."

"What? It's what it's commonly called. What do you want me to call it? Vagina? Pee pee? I'd sound like a kid."

"Fine." Sarada groaned in defeat.

Just as Boruto said, he sat on the bed, fully naked with his dick standing in attention. Sarada sat down on the floor so she was level with it and looked at it inquisitively.

"You're hard, right? That's the erection they were talking about in class?" she asked.

"Yeah."

"So that means you're aroused, aren't you?"

"Well duh! I just stared and felt up your boobs a while ago, it's a natural reaction for boys."

"Hey, something pink is poking out."

"It's the head of my dick. You gotta pull back my foreskin to expose it."

"Okay. May I touch it?"

"Of course."

And then Sarada slowly brought her right hand to take hold of his dick. Her hand was shaking but that's just because even her heart was beating crazy fast. The touch of her hand made Boruto shiver and his dick twitched. He's never had a hand other than his own touch him there before.

"Wow. It really is hard. And warm." Sarada whispered in awe. Boruto said she had to peel down the foreskin to show the head. She didn't know what to do so he just pulled the skin down and there came out the pink head of his dick. She saw a small opening that she's not seen before. After all, Boruto's dick was soft before and his foreskin covered it when they were kids.

"Is this where you pee?" Sarada ask out of curiosity as she looked up to face Boruto.

"Yeah."

"I wanna see it. How you pee?"

"Wait, what? You wanna see me pee?"

"I've never seen a boy pee before. Your penis is definitely different from what I have so I'm curious."

"It can't be helped then. Though it's kinda hard to pee when it's hard."

"Let's go to the bathroom." Sarada suggested.

"Okay then. But you have to show me how you pee too."

Boruto then pulled up his pants to cover his dick. Sarada put her bra back on as well as her shirt. Seeing this, Boruto followed and donned his own shirt too. Then the two of them went out of her bedroom and went inside the bathroom down the hall. Once inside, they locked it.

Luckily, the trip made Boruto's dick turn back soft which would make it easier for him to pee. Sarada was there ready to watch him and it kind of made Boruto feel excited. He dropped his shorts and underwear down again and out came his now limp dick.

Sarada was surprised at how different it looked now. It was smaller, like only 2 inches. It looked cute. But Boruto would probably kill her if she said that out loud.

"Okay then, watch the show." Boruto announced as he pulled his foreskin back a bit and started to pee. The yellow liquid flowed like water from a hose with a narrow nozzle, with Boruto aiming his dick at the side of the toilet bowl to keep the noise down and to avoid any splattering. Sarada watched mesmerized at the sight. It took around 10 seconds before Boruto finished peeing.

"There, filled your curiosity now?" he said as he shook his dick to get rid of the remaining droplets of his pee.

"Yeah. Must be nice to be able to pee while standing." she said.

"What, you want to have a dick for peeing?" Boruto teased.

"No. Of course not. I'm perfectly fine with what I have."

"Well, you've seen me all naked, touched my dick and watched me pee. It's your turn now, Sarada."

"Do I really have to pee in front of you?"

"I peed in front of you and let you have a close look. I just wanna see where your pee comes from."

"But haven't you seen a girl pee before? I mean, you have a sister. You must have seen her pee when you were younger."

"Yeah, I've seen her. I know you girls have to sit down on the toilet cause you don't have a dick to aim with, but it's not like I said, "Hey Hima, can your big bro watch you pee and take a close look at your pee-pee?" and then look closely at her pussy while she did."

"You have a point. And you did let me watch you so I suppose it's fair." Sarada said. Now it was her turn to take her shorts and panties off. She didn't hesitate this time anymore. The consciousness she had when she showed him her boobs a while ago was gone. Then she sat on the toilet bowl and spread her legs for Boruto to see her.

"Aw, it looks cute." Boruto said as he looked at her pussy. "Hey, show me the parts that we talked about at school. I always thought girls only had a slit there and that's it. I didn't know you had other parts inside when you spread it open."

"Okay then. Just, don't stare too much." Sarada agreed and she held her outer lips with each hand and spread them out, showing Boruto what was inside.

"Cool. It's the same color as the head of my dick. So, where do you pee from there?"

"I have a small opening near the top." Sarada looked down and brought her fingers near her urethra and then spread that part, making the opening a bit larger for Boruto to see.

"Oh. So that's where you pee. I thought you girls pee from that big opening." Boruto said in amazement.

"I also didn't know that before until I had my first menstruation. My mom explained to me that it's from the vagina where the blood comes from and that it's from the hole above where the pee comes out. I looked at it using a mirror."

"Oh. Show it to me then. I wanna see your pee come out."

"Alright. I'll try." And Sarada relaxed and then tried to pee. It took a few seconds and then there came a sprinkle of her pee which then turned into a stronger and more directed flow down the toilet. She had to turn her head away for doing such an embarrassing thing in front of Boruto, while his eyes were glued at the scene in front of him.

After a few seconds, the stream of pee turned into dribbles until no more came out. Sarada was about to look back to face Boruto but she squeaked as she felt a hand cupping her pussy.

"Bo-boruto! What are you doing?!" she called him in panic.

"I'm just taking a closer look. I let you hold my dick earlier didn't I?"

"You… yeah, but you could have asked me first."

"Hey, you actually have a little bit of hair on top." Boruto noted as he saw the short stubs of pubic hair on her mound. Then he brought his other hand and used both his thumbs to spread her lips, revealing the opening again like what Sarada did when she peed. "It's hard to believe girls are so different in this area. Like we don't look anything similar at all."

"How long are you gonna look at it perv?" Sarada asked impatiently.

"Wait, I'm just trying to see… there." he pointed out as he spread her bigger opening more. It wasn't like the ones he saw at the porn movies he secretly watched. Yes, he's watched porn before. He might not be that all familiar with the anatomy but he knows the more sexual purpose of a boy and girl's private parts. What he saw was her hymen, not that he knew what it was called. He wasn't even sure that was what he saw, but he just knew girls who aren't virgins anymore have bigger openings because a dick has already been inside. Not that he thought Sarada wasn't a virgin anymore. She wasn't really the type to do those things. She looked to be oblivious to that topic still.

"Hey have you ever…" Boruto was about to ask her but then they heard the sound of the front door opening.

"Someone's here." Sarada whispered. Boruto quickly retreated and Sarada quickly stood up to bring her panties and shorts up. "It might be my mom. Stay here and I'll sneak back to my room."

"Okay."

Then quickly, Sarada went out of the bathroom and tiptoed towards her room, her heart beating rapidly at the thought of possibly being caught doing all those stuff she just did with Boruto. She opened her bedroom door and was about to go inside when she heard her mom call her name.

"Sarada, are you up there?"

Her heart almost skipped a beat as she heard her mom but she knew she had to act cool or else risk suspicion.

"Yes mama." she answered back.

"Is Boruto-kun here too? I saw another pair of shoes at the rack."

"Yes. He went for a visit. He's uhm… borrowing some of my PS4 discs." she said, making up an excuse on the spot.

"Okay then. I'll prepare you two some snacks so come down here in a few minutes when I call you."

"Okay Mama."

After a few seconds and her mom didn't ask her any more questions, she gave out a big sigh of relief. Then she heard the bathroom door open and out came Boruto. She signaled to him to go inside her room and the two of them went back inside.

"So, everything okay?" Boruto asked, a bit worried too on his side. He knew how scary Sarada's mom could be. If she ever found out what he and Sarada just did, that he saw her naked, touched her in those places and that he was the one to propose it, he might find himself 6 feet under ground

"Yeah. We're safe."

"That was close. I thought your mom doesn't come home at this time."

"She usually doesn't so I'm surprised too."

"So, today was fun. I learned a lot." Boruto grinned.

"You only found it fun 'cause you're a perv." Sarada threw back, rolling her eyes again.

"Come on Sarada. I'm just curious. And you definitely were curious too."

"Fine, Mr. I'm-not-a-perv-just-curious. Mom said she'll prepare snacks for us. And also, I told her you came here to borrow some of my PS4 games."

"An excuse for me to come here huh? That's actually a good idea. What games do you have?"

"Well, I do have Assassin's Creed Odyssey and Tomb Raider. You like those type of games right?"

"Yeah. And you have them? Man, I wanna play those. I didn't know you play adventure games." Boruto said excitedly.

"I like Greek Mythology and you can play as a girl in those games."

"You never told me about that. I have other games like that if you wanna borrow. I'll give you a list of mine and you give me a list of yours later. I can come by your house again tomorrow to pick them up."

"That does sound good. Okay."

"That's a deal then. By the way, there was something else I wanted to ask you a while ago in the bathroom, just before your mom arrived." Boruto said with a lowered voice.

"What is it? Another pervy thing you wanna 'learn' about?" Sarada whispered in return.

"Yeah. Have you ever masturbated before?"

"Huh?"

"You haven't?"

"I don't even know what that word means."

"Like touch yourself down there."

"Down there?" Sarada asked in confusion, but because of the things that happened, she got the gist Boruto was talking about her private part.

"Yeah, your pussy. Like, have you rubbed it before?"

"What? No. Why would I do that?"

"So you're really clueless about it huh?"

"What is it? Should I know about it?"

"You've gotten curious have you? I can tell you about it tomorrow. Let's meet here again. I'm sure the other girls already know about it. And I promise, you'll like it a lot."

Sarada scrunched her eyebrows at Boruto, not understanding most of what he was saying. But she was getting even more curious. They've already seen each other naked and touched each other, there's nothing more to hide and be embarrassed about.

"Okay. Let's meet here again after school."

"Sarada, Boruto!" they heard her mom call out from downstairs. "Snacks are ready. Come down here."

"Mom's calling us. We should go down."

"Alright, let's go."
